Abstract Objectives Branched chain fatty acids (BCFA) are rumen-derived fatty acids comprising about 2% of bovine milk fatty acids. BCFA possess anti-inflammatory properties and enriching the BCFA content of bovine milk may provide human health benefits of milk consumption. In this work, we determined whether high vs low forage diets impact the BCFA content of milk from Holstein cows and identified fatty acid phenotypes in high vs low BCFA-containing milks. Methods In this study, 62 Holstein cows were fed for 70 days, in a cross-over design fashion, either a high forage: concentrate (HF: C) diet or a low forage: concentrate (LF: C) diet. At the end of the 70-day feeding period, cows were switched to the alternate feeding arm. Milk samples were collected prior to the start of the first feeding period and at the end of each treatment period. Milk fatty acid content was determined by fatty acid methyl ester analysis. Paired t-tests, one-way ANOVA, and sparse partial least squares discriminant analysis (sPLSDA) were used to analyze the data. Results The total milk fatty acid concentration at the end of HF: C diet period was greater than that of the LF: C diet (4.2 ± 0.9 g/100 mL vs 3.95 ± 0.9 g/100 mL). sPLSDA demonstrated clear separation of the dietary treatments, with BCFA and odd-chain fatty acids as primary determinants. Total BCFA content was elevated by HF: C intake (1.86 ± 0.13%) vs LF: C intake (1.77 ± 0.14%). Quintile separation of high vs low BCFA milks resulted in 4 groups (n = 12) HF: C/low BCFA, HF: C/high BCFA; LF: C/low BCFA, and LF: C/high BCFA. The total BCFA contents of the low BCFA milks were not different regardless of forage content (1.70 ± 0.06% and 1.61 ± 0.04%) and were lower than the high BFCA milks (2.04 ± 0.11% and 1.98 ± 0.11%). Milks from the high BCFA quintiles had lower saturated fatty acid (SFA) content but higher oleic acid content than milks from the low BCFA quintiles. Of the 62 cows, 5 cows were identified as high BCFA producers and 6 cows as low BCFA producers regardless of the LF: C or HF: C diets. Conclusions The data demonstrate that the BCFA content of milk is diet-sensitive but variation in cow responses suggest factors such as genotype or rumen microbiome composition may play significant roles. The potential to produce milk with high BCFA content and lower SFA content needs further study. Funding Sources USDA-ARS Projects 3062–53000-001–00D, 5090–31000-025–00D, 80–8040-05–01-0000–0000.

Abstract Background and study aims Polyethylene glycol (PEG) bowel preparations are effective but associated with high ingestion volume. In this study, 1-L PEG and 2-L PEG preparations were compared in a randomized, colonoscopist-blinded, single-center trial. Patients and methods Patients were aged > 18 years, required colonoscopy, and provided informed consent. Randomization was 1:1 to 1-L PEG or 2-L PEG, based on hospital identification number (odd or even). Preparations were administered using same-day dosing adjusted for colonoscopy start time. The primary endpoint was successful bowel preparation on the Boston Bowel Preparation Scale (BBPS) (no segment scored < 2). Results A total of 852 patients were randomized. In the intention-to-treat (ITT) population, significantly more patients had diabetes in the 2-L PEG arm, resulting in the creation of the modified-ITT population (mITT) that excluded diabetic patients to correct the imbalance (1-L PEG, n = 239; 2-L PEG, n = 238). In the mITT, there was no significant difference in successful cleansing between 1-L PEG and 2-L PEG (88.3 % vs. 82.4 %; P = 0.067). Excellent cleansing (BBPS 7–9; no segment < 2) was significantly improved with 1-L PEG (60.7 % vs. 50.4 %; P < 0.024), as were mean scores in the right and left colon (right: 2.47 vs. 2.30; P < 0.008; left: 2.55 vs. 2.39; P = 0.008). Adverse events were mild to moderate in intensity and none resulted in discontinuation. Rates of nausea and vomiting were significantly higher with 1-L PEG, but that did not affect successful cleansing. Conclusions The lower-volume 1-L PEG was associated with higher levels of excellent bowel cleansing and greater mean segmental scores on the BBPS than 2-L PEG.

Abstract Multiple myeloma (MM) is characterized by a high genomic instability that involves both ploidy and structural rearrangements. Nearly half of MM tumors are non-hyperdiploid and are frequently associated with 13q deletion and chromosomal translocations involving the immunoglobulin heavy chain (IGH) locus on chromosome 14q32. The remaining tumors are hyperdiploid, showing low prevalence of both IGH translocations and chromosome 13 deletions. Our study was aimed at providing insights into the genomic heterogeneity associated with plasma cell neoplasms by defining the genome-wide pattern of genetic lesions in a representative and stratified panel of MM patients. To this end, genome-wide profiling data of 45 plasma cell dyscrasia patients (41 MM and 4 plasma cell leukemia) were generated on GeneChip® Human Mapping 50K Xba SNP arrays, and the local DNA copy number variations were calculated using the DNAcopy Bioconductor package. The patients were clustered using the non-negative matrix factorization (NMF) algorithm to identify, within the natural grouping of profiles, the strongest clusters on the basis of their genomic characteristics. We identified three consistent clusters, characterized byrecurrent gains of odd-chromosomes, suggestive of the hyperdiploid status (Group A),high frequency of chromosome 13 deletion and 1q gains (Group B), orhigh frequency of chromosomes 13, 14, 16 and 22 deletions and losses of 1p and 4p regions, together with some cases showing 1q gains (Group C). To determine whether peculiar transcription fingerprints characterized these groups, gene expression profiles of 40 out of 45 corresponding samples generated on GeneChip® HG-U133A arrays were analyzed using the Prediction Analysis of Microarray (PAM) software. The multi-class analysis identified 229 transcripts (corresponding to 195 genes), which specifically marked the three groups. In particular, Group A was characterized by the overexpression of genes involved in the translational machinery or thought to be involved in MM pathogenesis such as the HGF, the tumor necrosis factor ligand TRAIL, DKK1, and c-KIT. Upregulation of the CKS1B gene was present in Group B and C, most likely reflecting the high frequencies of 1q gains in tumors within group B and C and its consequent deregulation. Group C was marked by the specific downregulation of genes mainly mapped to 1p arm: AMPD1, CSDE1, AKR1A1 and the PRKACB kinase, suggesting a relationship with the recurrent 1p loss within the group. Our data further supported the notion that structural abnormalities in multiple myeloma are associated with gene expression imbalances, and provide novel analytical approaches for the identification of genetic lesions and molecular patterns of the disease.

This paper proposes a fast query tree-based (FQT) algorithm for anti-collision in RFID system. Tags to be identified would be grouped by a reader randomly at beginning, and the reader identifies a group of tags and records the quantity of tags. Then reckons the number of all tags and carries out optimized group again. In identification process, the prefix of queries would add two bits in odd rounds, and one bit in even rounds. The results of analysis and simulation show that FQT algorithm can obtain the better performance than QT algorithm.

ABSTRACT Nitrate-reducing enrichments, amended with n-hexadecane, were established with petroleum-contaminated sediment from Onondaga Lake. Cultures were serially diluted to yield a sediment-free consortium. Clone libraries and denaturing gradient gel electrophoresis analysis of 16S rRNA gene community PCR products indicated the presence of uncultured alpha- and betaproteobacteria similar to those detected in contaminated, denitrifying environments. Cultures were incubated with H34-hexadecane, fully deuterated hexadecane (d 34-hexadecane), or H34-hexadecane and NaH13CO3. Gas chromatography-mass spectrometry analysis of silylated metabolites resulted in the identification of [H29]pentadecanoic acid, [H25]tridecanoic acid, [1-13C]pentadecanoic acid, [3-13C]heptadecanoic acid, [3-13C]10-methylheptadecanoic acid, and d 27-pentadecanoic, d 25-, and d 2 4-tridecanoic acids. The identification of these metabolites suggests a carbon addition at the C-3 position of hexadecane, with subsequent β-oxidation and transformation reactions (chain elongation and C-10 methylation) that predominantly produce fatty acids with odd numbers of carbons. Mineralization of [1-14C]hexadecane was demonstrated based on the recovery of 14CO2 in active cultures.

ABSTRACT The alkane- and alkene-degrading, marine sulfate-reducing bacterium Desulfatibacillum aliphaticivorans strain CV2803T, known to oxidize n-alkanes anaerobically by fumarate addition at C-2, was investigated for its 1-alkene metabolism. The total cellular fatty acids of this strain were predominantly C-(even number) (C-even) when it was grown on C-even 1-alkenes and predominantly C-(odd number) (C-odd) when it was grown on C-odd 1-alkenes. Detailed analyses of those fatty acids by gas chromatography-mass spectrometry after 6- to 10-week incubations allowed the identification of saturated 2- and 4-ethyl-, 2- and 4-methyl-, and monounsaturated 4-methyl-branched fatty acids with chain lengths that correlated with those of the 1-alkene. The growth of D. aliphaticivorans on (per)deuterated 1-alkenes provided direct evidence of the anaerobic transformation of these alkenes into the corresponding 1-alcohols and into linear as well as 10- and 4-methyl-branched fatty acids. Experiments performed with [13C]bicarbonate indicated that the initial activation of 1-alkene by the addition of inorganic carbon does not occur. These results demonstrate that D. aliphaticivorans metabolizes 1-alkene by the oxidation of the double bond at C-1 and by the subterminal addition of organic carbon at both ends of the molecule [C-2 and C-(ω-1)]. The detection of ethyl-branched fatty acids from unlabeled 1-alkenes further suggests that carbon addition also occurs at C-3. Alkylsuccinates were not observed as potential initial intermediates in alkene metabolism. Based on our observations, the first pathways for anaerobic 1-alkene metabolism in an anaerobic bacterium are proposed. Those pathways indicate that diverse initial reactions of 1-alkene activation can occur simultaneously in the same strain of sulfate-reducing bacterium.

Although polynomial NARX models have been intensively used in nonlinear system identification, few papers discussed how to relate the inner nonlinearities to specific types of clusters and regressors. The objective of this paper is to discuss this relationship for a class of systems that contain even or odd nonlinearities. This class covers block-structured models (Hammerstein, Wiener, and others) and systems with dynamic nonlinearities. To achieve the paper’s aim, a deep frequency-domain analysis is performed. For each type of nonlinearity, all the NARX clusters are investigated and the results show that each regressor type provides specific nonlinear contribution. The investigation is based on an output power spectra analysis when a specific multisinusoidal excitation is applied. According to the spectral contributions in some of the frequency lines, the nonlinearity classification is possible. By applying the same procedure to the clusters, one interprets how these clusters can (or not) contribute to explain the system nonlinearity. The paper findings have two major impacts: (i) one gains deep knowledge on how the nonlinearities are coded by the clusters, and (ii) this information can be used, for instance, to aid a structure selection procedure (ERR, term clustering, etc.) during the discarding of the clusters which are not able to explain the system nonlinear behavior. Some practical and experimental aspects are discussed, while numerical examples are presented to show the validity of the theoretical analysis.

Ruins are representative of European values and illustrative of European history and heritage and our aim should be to raise awareness of this heritage in order to create a stronger identification with Europe and a further European integration as well.
While people are living in and around World Heritage sites, their role in heritage processes and management has changed considerably.
Nowadays we must connect the conservation goals with the objective of smart, inclusive and sustainable growth. Local communities must be encouraged to use their local cultural assets as a springboard through a process whereby local actors, are encouraged to assume an active stewardship over the heritage and are empowered develop that heritage in a responsible, profitable and sustainable manner.
In their evocative and fascinating image, ruins must be returned to the contemporary life from which they often appear, instead, dramatically separated.
Interventions on ruins appear difficult and risky, on the boundary line between archaeological and architectural restoration.
The contemporary architectural interventions on the ruin oscillate from conservation to reintegration, up to the absolute extremism consisting in the reconstruction, considered acceptable and suitable only if based on the contemporary design that, from the knowledge of the history, leads to a creative and modern form and image of the architectural work.

ABSTRACT Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen worldwide, which has emerged over the past 30 years as a leading cause of both nosocomial and community-acquired infections. Accurate and rapid identification of MRSA in clinical specimens is essential for timely decision on effective antimicrobial chemotherapy. Aim: The present study was conducted to compare two conventional phenotypic methods, oxacillin disk diffusion (ODD) Aim: The present study was conducted to compare two conventional phenotypic methods, oxacillin disk diffusion (ODD) method and mannitol salt agar (MSA) with oxacillin, with polymerase chain reaction (PCR) for mecA gene (as standard). Materials and Methods: A total of 165 consecutive clinical isolates of S. aureus received at the Department of Microbiology in our tertiary care teaching hospital were included in the study. All the isolates were subjected to ODD (1 μg) method, culture in MSA with oxacillin, and PCR for mecA gene. Results: The sensitivity and specificity of ODD test were found to be 93.5% (86.4-97.3%) and 83.5% (79.2-85.8%), respectively, and that of MSA with oxacillin were found to be 87.1% (79.5-92.3%) and 89.3% (84.8-92.5%), respectively. The time taken for diagnosing MRSA by conventional methods is 48-72 h, which is more as compared to PCR which takes 18-24 h. Conclusion: This study recommends advocating PCR for mecA gene on a regular basis for detecting methicillin resistance in S. aureus isolates isolated from sterile body fluids or from special units such as intensive care units.

Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.

Use of time-compressed speech stimuli has been found to be clinically effective in differential diagnosis of lesions of the temporal lobe. However, notably absent from the literature is information concerning performance of adults on time-compressed closed-set speech discrimination tasks. The goal of this study mas to compare performance of 12 males and 12 females between age 50 and age 70 on a time-compressed closed-set speech discrimination test against the performance of 12 males and 12 females between age 10 and age 28 on the same task. The Word Intelligibility by Picture Identification test (WPI) was presented in both non-compressed and time-compressed conditions to all subjects. Previous research suggests that a difference in performance between age groups and between males and females in the older age group should be expected. Average results indicated negligible differences between age or gender groups under any of the conditions tested. Additionally, the test yielded perfect or near perfect scores for all subjects in the non-compressed condition. Lack of differentiation of results suggests that the Word Intelligibility by Picture Identification CUIPI) may be insensitive to the discrimination disorders expected in older adults, that the subjects included in the study were atypical of older adults in general and therefore such discrimination disorders did not exist in the sample, or that the subjects in the study uiere able to apply some type of compensatory strategies which resulted in the unexpected performance.

In this thesis, we study the problem of identifying an anomalous arm in a multi-armed bandit as quickly as possible, subject to an upper bound on the error probability. Also known as odd arm identification, this problem falls within the class of optimal stopping problems in decision theory and can be embedded within the framework of active sequential hypothesis testing. Prior works on odd arm identification dealt with independent and identically distributed observations from each arm. We provide the first known extension to the case of Markov observations from each arm. Our analysis and results are in the asymptotic regime of vanishing error probability.
We associate with each arm an ergodic discrete time Markov process that evolves on a common, finite state space. The notion of anomaly is that the transition probability matrix (TPM) of the Markov process of one of the arms (the {\em odd arm}) is some $P_{1}$, and that of each non-odd arm is a different $P_{2}$, $P_{2}\neq P_{1}$. A learning agent whose goal it is to find the odd arm samples the arms sequentially, one at any given time, and observes the state of the Markov process of the sampled arm. The Markov processes of the unobserved arms may either remain frozen at their last observed states until their next sampling instant ({\em rested arms}) or continue to undergo state evolution ({\em restless arms}). The TPMs $P_{1}$ and $P_{2}$ may be known to the learning agent beforehand or unknown. We analyse the following cases: (a) rested arms with TPMs unknown, (b) restless arms with TPMs known, and (c) restless arms with TPMs unknown. For each of these cases, we first present an asymptotic lower bound on the {\color{black} growth rate of the }expected time required to find the odd arm, and subsequently devise a sequential arm selection policy which we show achieves the lower bound and is therefore asymptotically optimal.
A key ingredient in our analysis of the setting of rested arms is the observation that for the Markov process of each arm, the long term fraction of entries into a state is equal to the long term fraction of exits from the state (global balance). When the arms are restless, it is necessary for the learning agent to keep track of the time since each arm was last sampled (arm's {\em delay}) and the state of each arm when it was last sampled (arm's {\em last observed state}). We show that the arm delays and the last observed states form a controlled Markov process which is ergodic under any stationary arm selection policy that picks each arm with a strictly positive probability. Our approach of considering the delays and the last observed states of all the arms jointly offers a global perspective of the arms and serves as a `lift' from the local perspective of dealing with the delay and the last observed state of each arm separately, one that is suggested by the prior works. Lastly, when the TPMs are unknown and have to be estimated along the way, it is important to ensure that the estimates converge almost surely to their true values asymptotically, i.e., the system is {\em identifiable}. We show identifiability follows from the ergodic theorem in the rested case, and provide sufficient conditions for it in the restless case.Department of Science and Technology, Ministry of Human Resource Development, Center for Networked Intelligence, Robert Bosch Center for Cyber-Physical Systems

This book is the first comprehensive study of postwar antisemitism in the Netherlands. It focuses on the way stereotypes are passed on from one decade to the next, as reflected in public debates, the mass media, protests and commemorations, and everyday interactions. The Holocaust, Israel and 'the Jew' explores the ways in which old stories and phrases relating to 'the stereotypical Jew' are recycled and modified for new uses, linking the antisemitism of the early postwar years to its enduring manifestations in today's world. The Dutch case is interesting because of the apparent contrast between the Netherlands' famous tradition of tolerance and the large numbers of Jews who were deported and murdered in the Second World War. The book sheds light on the dark side of this so-called 'Dutch paradox,' in manifestations of aversion and guilt after 1945. In this context, the abusive taunt 'They forgot to gas you' can be seen as the first radical expression of postwar antisemitism as well as an indication of how the Holocaust came to be turned against the Jews. The identification of 'the Jew' with the gas chamber spread from the streets to football stadiums, and from verbal abuse to pamphlet and protest. The slogan 'Hamas, Hamas all the Jews to the gas' indicates that Israel became a second marker of postwar antisemitism. The chapters cover themes including soccer-related antisemitism, Jewish responses, philosemitism, antisemitism in Dutch-Moroccan and Dutch- Turkish communities, contentious acts of remembrance, the neo-Nazi tradition, and the legacy of Theo van Gogh. The book concludes with a lengthy epilogue on 'the Jew' in the politics of the radical right, the attacks in Paris in 2015, and the refugee crisis. The stereotype of 'the Jew' appears to be transferable to other minorities. Now also available as paperback!

The aims of this chapter are twofold. First, it outlines methods by which high-risk offenders with personality disorder can be identified in large samples of offenders. It presents a summary of the available evidence that relates to this task, while also drawing on the authors’ experience of implementing systems of case identification while working in the probation service in the UK. It is argued that adopting proactive systems of case identification not only is achievable but also holds a number of potential benefits. Second, the chapter considers approaches to formulation in the Offender Personality Disorder (OPD) community pathways services. Following a review of the literature and available models, the authors discuss how the London Pathways Partnership selected its current approach and provide a description of its practical application and the lessons learned from our experiences. The chapter ends with a discussion of future directions for both case identification and formulation.

This chapter looks at how OCD is typically manifested in the school environment. Various symptom presentations are reviewed, each with multiple illustrations of how they might be manifested in students with OCD. Examination of how treatment protocols can be developed to reverse and minimize the effects of the disorder on school-related functioning is followed by an exploration of how school personnel, together with mental health professionals and parents, can become active participants in OCD therapy. A strong emphasis throughout is placed on educating the educators, and virtually all school personnel, on what OCD is, how it might appear in the academic setting, and how to respond to it. The goal is to promote early identification of the disorder and appropriate referral for treatment, as well as an understanding of how school personnel can be a part of the treatment process.

Obsessive-compulsive disorder (OCD) is a severe psychiatric disorder characterized by obsessions and/or compulsions. Only half of patients respond to first-line pharmacological treatments, and symptom relief is typically partial, even in responders. Gaining a better understanding of OCD etiology could lead to better treatments, and potentially to prevention. Animal models are a useful tool for studying neurobiological mechanisms underlying psychiatric phenotypes. Effective use of animal models requires identification of reliable, quantifiable features of the disorder of interest that can be measured across species. The modeled phenotypes then require assessment for predictive validity: the accuracy with which a model makes accurate predictions about the human condition. Once a model has been shown to make accurate predictions, using it to study neurobiological mechanisms is justified. The validity of spontaneous and induced rodent models of OCD is reviewed in this chapter.

Regular physical activity in old age is widely recommended as an effective way to prevent chronic diseases and maintain well-being. Nevertheless, sports participation carries the risk of injury. In elderly people, the risk of injury is greater due to age-related pathophysiological changes and concomitant chronic conditions. Available data indicate an increasing number of injuries among older people, which is associated with there being more older people and an increasing number of these people are participating in sports and physical exercise. An appropriate identification of risk factors for injury and education of older people can reduce the incidence of injuries. Methods of preventing injuries include protective equipment such as helmets, warming up, and properly designed training programmes. Health benefits of participation in regular physical activity adjusted to health status and physical functioning outweigh hazards of sport-related injuries, even in advanced age.

Many psychiatric disorders of childhood have a chronic course. As such, they impact multiple developmental epochs and negatively influence developmental trajectories. While early identification and intervention may minimize, or even prevent, symptoms being carried into adulthood, the availability of evidence-based treatments is sparse in children and adolescents compared to adult populations. Establishing effective interventions for psychiatric symptoms presenting in childhood is critical given the chronic course of most psychiatric disorders. This chapter describes psychopharmacological and psychosocial interventions used for the treatment of childhood psychiatric conditions, with an emphasis on empirically supported treatments. Both symptom- and diagnosis-specific approaches are described as well as the use of combined interventions for the following childhood psychiatric conditions: autism spectrum disorder (ASD), intellectual disability (ID), attention-deficit/hyperactivity disorder (ADHD), anxiety, depression, obsessive compulsive disorder (OCD), chronic tic disorders, eating disorders, and conduct problems.

Although customary international law (CIL) has been central to international law from its inception, it is often misunderstood. This edited volume remedies that problem by tracing the history of CIL and provides an in-depth study of its theory, practice, and interpretation. Its chapters tackle the big questions which surround this source of international law such as: what are the rules that regulate the functioning of CIL as a source of international law? Can CIL be interpreted? Where do lines between identification, interpretation, application, and modification of a rule of CIL lie? Using recent developments, this volume revisits old debates and resolves them by proffering new and innovative solutions. With detailed examples from international and national courts, it places CIL in a range of settings to explain, explore and reflect upon this developing and highly significant field. This title is also available as Open Access on Cambridge Core.

This book considers the null-subject phenomenon, whereby some languages lack an overtly realized referential subject in specific contexts. In generative syntax—the approach adopted in this volume—the phenomenon has traditionally been explained in terms of a ‘pro-drop’ parameter with associated cluster properties; more recently, however, it has become clear that pro-drop phenomena do not always correlate with all the initially predicted cluster properties. This volume returns to the centre of the debate surrounding the empirical phenomena associated with null subjects. Experts in the field explore the cluster properties associated with pro-drop; the types of null category involved in null-subject phenomena and their identification; and the typology of null-subject languages, with a special focus on partial null-subject languages. Chapters include both novel empirical data and new theoretical analyses covering the major approaches to null subjects in generative grammar. A wide range of languages are examined, ranging from the most commonly studied in research into null subjects, such as Finnish and Italian, to lesser-studied languages such as Vietnamese and Polish, minority languages such as Cimbrian and Kashubian, and historical varieties such as Old French and Old High German. The research presented also contributes to the understanding of other key syntactic phenomena, such as the nature of control, the role of information structure and semantics in syntax, the mechanisms of language change, and the formalization of language variation.

In Leonardo’s Salvator Mundi and the Collecting of Leonardo in the Stuart Courts the ‘Three Salvateers’—Robert Simon, Martin Kemp and Margaret Dalivalle—give a first-hand account of the discovery of the lost Renaissance masterpiece; from its purchase for $1,175 in a New Orleans auction house in 2005, to the worldwide media spectacle of its sale to a Saudi prince for $450 million in 2017. A behind-the-scenes view of the painstaking processes of identification, consultation, scientific analysis, conservation, and archival research that underpinned the attribution of the painting to Leonardo, the book presents a consideration of the place of the painting in Leonardo’s body of work. Exploring the meaning of the painting in terms of Renaissance theology, it considers the identity of its original patron or intended recipient. Unravelling networks of early modern art dealers and collectors in Europe, it traces the emerging reception of Leonardo during the sixteenth and seventeenth centuries. It was in Enlightenment Britain that the idea of Leonardo as artist–scientist took hold of the public imagination. This book examines the ‘invention’ of Leonardo through the unique prism of the Stuart courts. The documented presence of three paintings of Christ attributed to Leonardo in the vicinity of the seventeenth-century British Royal Collection is both extraordinary and perplexing. Today, Leonardo’s five-hundred-year-old Salvator has not yet disclosed its secret history.

AbstractDeceiving an adversary who may, e.g., attempt to reconnoiter a system before launching an attack, typically involves changing the system’s behavior such that it deceives the attacker while still permitting the system to perform its intended function. We develop techniques to achieve such deception by studying a proxy problem: malware detection.Researchers and anti-virus vendors have proposed DNNs for malware detection from raw bytes that do not require manual feature engineering. In this work, we propose an attack that interweaves binary-diversification techniques and optimization frameworks to mislead such DNNs while preserving the functionality of binaries. Unlike prior attacks, ours manipulates instructions that are a functional part of the binary, which makes it particularly challenging to defend against. We evaluated our attack against three DNNs in white- and black-box settings and found that it often achieved success rates near 100%. Moreover, we found that our attack can fool some commercial anti-viruses, in certain cases with a success rate of 85%. We explored several defenses, both new and old, and identified some that can foil over 80% of our evasion attempts. However, these defenses may still be susceptible to evasion by attacks, and so we advocate for augmenting malware-detection systems with methods that do not rely on machine learning.

AbstractAlthough radiogenic isotopes historically have been used in ore genesis studies for age dating and as tracers, here we document the use of regional- and continental-scale Sm–Nd isotope data and derived isotopic maps to assist with metallogenic interpretation, including the identification of metallogenic terranes. For the Sm–Nd system, calculated Nd model ages, which are time independent, are of most value for small-scale isotopic maps. Typically, one- or two-stage depleted mantle model ages (TDM, T2DM) are used to infer age when the isotope characteristics of the rock were in isotopic equilibrium with a modelled (mantle) reservoir. An additional advantage is that Nd model ages provide, with a number of assumptions, an estimate of the approximate age of continental crust in a region. Regional- and continental-scale Nd model age maps, constructed from rocks such as granites, which effectively sample the middle to lower crust, therefore, provide a proxy to constrain the nature of the crust within a region. They are of increasing use in metallogenic analysis, especially when combined with a mineral systems approach, which recognizes that mineral deposits are the result of geological processes, at a scales from the ore shoot to the craton. These maps can be used empirically and/or predictively to identify and target large parts of mineral systems that may be indicative, or form part of, metallogenic terranes. Examples presented here include observed spatial relationships between mineral provinces and isotopic domains; the identification of old and/or thick cratonic blocks; determination of tectonic regimes favorable for mineralization; identification of isotopically juvenile zones that may indicate rifts or primitive arcs; recognition of crustal breaks that define metallogenic terrane boundaries or delineate fluid pathways; and, as baseline maps. Of course, any analysis of Sm–Nd and similar isotopic maps are predicated on integration with geological, geochemical and geophysical information data. In the future, research in this area should focus on the spatial and temporal evolution of the whole lithosphere at the province- to global-scales to more effectively targeting mineral exploration. This must involve integration of radiogenic isotopic data with other data, in particular, geophysical data, which has the advantage of being able to directly image the crust and lithosphere and being of a more continuous nature as compared to invariably incomplete isotopic data sets.

AbstractHomelessness in later life is closely related to social exclusion and can cause further disadvantages in later life. This chapter explores the relationship between studies on older adult homelessness and the domains of social exclusion. A structure review process, in the form of a summative content analysis and a social network analysis, of all geriatrics and gerontology journals published in English was conducted. This review led to the identification of 59 articles on homelessness in older age as the research sample for this chapter. The patterns that emerged from summative content analysis and the social network analysis are visualised using GEPHI software. Our findings reveal the multidimensional aspects of old-age exclusion in the homelessness literature, and how homelessness can be a significant determinant of interrelated sets of disadvantages. Exclusion from services, amenities, and mobility and community and neighbourhood, and material and financial resources are the domains represented most in homelessness studies in the ageing literature. However, civic participation and socio-cultural aspects of social exclusion were partly ignored within this body of work.

This chapter is the third and last chapter in the book that is based on the scoping review of scholarship on the intersection of ethnicity/ race and ageing/ old age. This chapter brings attention to social relations, social support/ help and caregiving (receiving), which is the third theme that has received the most attention when it comes to the scholarship in question. Just as it is the case with the two previous chapters, this chapter exposes the trends observed, and the ways in which ethnicity and race are made sense of in this literature. By bringing attention on the angles of investigation that this literature most often relies on (e.g. relying on others’ identification instead of own identification and the meanings attach to that), this chapter shows not only which topics have received attention, but also which ones remain unexplored.

Abstract Throughout its history, the cinema of mainland China has displayed a particular affinity with Chinese opera in its different regional and national varieties. An overview of this intermedial history reveals how Chinese opera intermingled with film in myriad ways. This chapter suggests that an intermedial history of Chinese cinema, framed through the opera lens, blurs the divide between old and new media, socialist and postsocialist arts, theatrical and photographic ontology, foreign and national styles, operatic and realist modes, allowing for a more encompassing appreciation of what are, in effect, necessarily impure and hybrid artistic manifestations. The intermedial approach also encourages a reevaluation of Brecht’s misinterpretation of the antinaturalistic performances of Mei Lanfang and the Peking Opera as alienation effects. Instead, the intermedial relationship between cinema and opera purposely promotes spectatorial identification at both individual and collective levels. Ending with an analysis of Chen Kaige’s Farewell My Concubine (霸王别姬 Bawang Bie Ji, 1993), the chapter traces some vectors for a future comprehensive study of Chinese cinema’s intermedial history, one that will find in operatic theatre, among other arts, hybrid elements capable of inspiring new, nonteleological, and nonbinary configurations and understandings of history.

This chapter unpacks what is at stake in Old Futures’ identification of a queer cultural politics for speculative fiction, in terms of both of queer studies’ approaches to time and scholarship on futuristic cultural production. It offers a brief history of intersections between queerness and speculative temporality and their entanglement with gender and race, before describing the book’s archive and its framing of speculative fiction as a cultural logic that exceeds literary and media genre studies. The chapter also articulates the centrality of reproduction to the project, which crafts an alternative discourse around the dominant heteronormative temporalities that Lee Edelman influentially critiqued in his 2004 book, No Future. In queer studies, reproductive futurism has primarily been an object of critique. In contrast, Old Futures argue that there are many reproductive futurisms, often in conflict and contradiction with one another, whose complexities are unpacked throughout the book.

The Wanderer and The Ruin are productively read as eco-elegies: explorations of changing relationships within the Earth community. The Wanderer offers its audience an exemplary portrait of natural depression, a human pattern of exile, emotional trauma, and acceptance which relies on identification with the Earth community as a way of healing. The poem affirms the idea that other-than-human elements of Earth community can actively improve the mental state of their human neighbors and reconcile apocalyptic loss. The Ruin contrasts this apocalyptic imagery with an imagined future where the Earth community responds to, but ultimately outlasts, the destruction of human societies. These eco-elegies encourage audiences to consider the long view of Christian history, pacifying anxieties about human relationships with other-than-human.

This chapter presents the ways in which understandings of ethnicity and race have evolved, and what characterises the different perspectives on these social positions that are available (i.e. essentialism/ primordialism, structuralism/ circumstantialism and constructionism). In doing so, this chapter maps out what these different perspectives mean to how we make sense of the impact that ethnicity and race have in our lives, and explains why some scholars refer to ethnicity and race as background variables, while others regard them as social positions, locations or identification grounds. In doing so this chapter problematizes what previous research on the intersection of ethnicity/ race and ageing/ old age has shown as far as the understandings of ethnicity and race that inform this scholarship.

The article examines a fragment from The Tale of the Blinding of Vasilko Terebovlsky — a story about the feelings of the Vladimir-Volyn prince David Igorevich before committing the atrocity he had conceived. The author divides the description of David’s emotional state into several parts, which are analyzed separately. It is based on the identification of literary parallels that are used to construct the story about the prince’s feelings. The identification of sources and related texts for the analyzed passage helps to understand the meaning of the description of the villain’s emotions. At first, the focus of the research is on the phrase “ne bѣ <…> glasa ni poslushan’ӕ” (“there was neither voice nor hearing”). Then the meaning of the verb “үzhasl”sѧ” (“was horrified”) and its role in the story of David’s feelings are explored. Here, in addition to identifying a literary parallel to the fragment, other examples from The Tale of Bygone Years containing words with the root “үzhas” (“horror”) are analyzed. The paper ends with the analysis of the mention of “lest’” (“flattery”), which David “imѣӕ v serdtsi” (“has in his heart”). The findings help to clarify how to understand the description of prince’s emotional state and what the function of the story in chronicle narrative is.

Birefringence of ice causes inner edges of refraction halos to be polarized. The direction of this polarization relates directly with the projection of the crystal optic axis (C-axis) onto the sky. Hence, the inner-edge polarisation can serve as an observational diagnostic for determining the actual nature of halo arcs that resembles each other closely. It can be e.g. decisive for the identification of a spot that might be either a 44° parhelion or a 46° parhelion, of an arc that might be either a 22° sunvex Parry arc or a 20° Parroid arc that arises from plate-oriented pyramidal crystals, and of an arc that might be either a 22° suncave Parry arc or a 23° Parroid arc from plate-oriented pyramidal crystals (with Parriod arcs I mean arcs that arise from a wedge in a doubly oriented pyramidal crystal for which the refracting edge is horizontal). Polarization properties of other rare arcs will be discussed. Practical hints are given for observing the inner edge polarization of halos, arcs and spots.

Fault detection and identification (FDI) are important tasks in most modern industrial and mechanical systems and processes. Many of these systems are most naturally modeled by differential algebraic equations. One approach to FDI is based on the use of observers and filters to detect and identify faults. The method presented here uses the least squares completion to compute an ODE that contains the solution of the DAE and applies the observer directly to this ODE. Robustness with respect to disturbances is also addressed by a frequency filtering technique.

A numerical simulation and system identification approach to the dynamic equilibrium of a catenary riser has been developed. A finite DOF representation of the dominant dynamics is constructed using frequency domain identification by applying nonlinear signal theory techniques on response data series when exciting the structure with sinusoidal motions at the top. Data series are obtained through numerical integration of a finite differences simulation model on the basis of the six nonlinear partial differential equations describing the riser dynamics. Dynamic equilibrium is mathematically formulated by the very same equations that implicate both geometric and hydrodynamic nonlinearities; the latter are depicted by Morison’s formula. Thus, spatio-temporal series are generated for riser bending moments induced by sinusoidal heave motions of various amplitudes and frequencies. These data are consequently transformed to the frequency domain where complex Singular Value Decomposition is applied in order to derive the full nonlinear spectrum. The significant harmonics of the riser’s spectrum for the bending moment on the 2D plane of reference are demonstrated to be the three lower odd harmonics and a set of orthogonal modes for these three significant harmonics is derived. The methodology proposed is finally applied to a typical test case for validation.

An effective non-model-based multiple damage identification method for beams by using a continuously scanning laser Doppler vibrometer (CSLDV) system is presented. Velocity response of a beam along a scan line under sinusoidal excitation is measured by the CSLDV system and a spatially dense operating deflection shape (ODS) of the beam along the scan line is obtained by the demodulation method from velocity response. The ODS of an associated undamaged beam is obtained by using a polynomial with a proper order to fit the ODS from the demodulation method. The curvature of an ODS (CODS) is used to identify abnormality induced by multiple damage. A curvature damage index (CDI) using differences between CODSs associated with ODSs that are obtained by the demodulation method and the polynomial fit is proposed to identify multiple damage. An auxiliary CDI obtained by averaging CDIs at different excitation frequencies is defined to further assist identification of multiple damage. Experiments on three beams with three damage on each beam in the form of three small cuts are conducted. Widths and depths of the three damage are varied from 3 mm to 9 mm with an increment of 3 mm and from 5% of thickness reduction to 15% with an increment of 5%, respectively, and their effects on ODSs, CODSs, and CDIs are investigated. Three frequencies close to natural frequencies of the beams and one randomly selected frequency that is not close to any natural frequencies of the beams are used as sinusoidal excitation frequencies. Each damage is successfully identified near regions with consistently high values of CDIs at different excitation frequencies when the damage is not close to a nodal point of an ODS. The three damage on each beam is successfully identified with the auxiliary CDI by obvious peaks at locations of the three damage.

<p>This study investigates the structural vulnerability of an old reinforced concrete dual wall-frame building structure, in Lisbon, Portugal. The building presents non-ductile behaviour and detailing typical of buildings designed before the introduction of modern seismic codes (pre– 1980). An analytical methodology is adopted in which multiple stripe analysis are performed on a three- dimensional model of the building. Fragility and vulnerability functions are developed for this structure, representative of a typology of old RC buildings. The fragility is derived taking into account the brittle shear failures of RC vertical members, i.e. columns and shear walls. The nonlinear dynamic analyses clearly indicate that these failure modes have a critical influence on the seismic performance of the structure. The results of this study can be used for seismic loss assessment and for the identification of appropriate mitigation strategies for this typology of existing RC buildings.</p>

The identification of strain critical regions on machinery and equipment, under operating conditions, can be accomplished by knowing the operating strain modes. Operating strain modes are interpreted as a dynamic strain distribution of the structure at a specific time or frequency. Strain measurements are conventionally obtained by strain gauge techniques. However, strain measurements with conventional strain gauges are not always possible, and the gauges are not reusable and cannot be moved from point to point when they have been attached to structures. In this paper, a post-processing technique based on Operating Deflection Shapes (ODS) is evaluated with an experimental test. Operational strain modes of an aluminum plate were identified from accelerations measured using tri-axial accelerometer. The operating modes were analyzed at frequencies close to the plate’s natural frequency, previously known by numerical simulation, in the frequency range 0–1000 Hz. The plate was excited with random white noise signal. We used the finite element method in the displacement to strain transformation. Operational modes were compared with simulated modes, which were obtained by modal superposition. The comparisons showed consistency between experimentally and numerically identified modes. Regions of greatest strain could be identified graphically in the color map regarding the minimum and maximum strain.

<p>Forensics engineering is generally focussed on analysing the aftermath of failures. It enables the diverse interacting factors which combine to initiate a collapse to be determined from the debris. Forensic engineering skills also need to be applied to identifying signs of increasing risks of failure in ageing infrastructure to prevent collapse by timely strengthening or replacement. Failures of concrete structures are increasing as deterioration reduces strength and embrittles critical parts. Often deficiencies arise from a combination of design errors and ambiguities in old standards when applied to innovations of type or scale, creating vulnerable details. Poor quality construction, including misplaced reinforcement and inadequate consideration of tolerances and variability in design, often become apparent after failure. But in routine inspection they are hidden by the opaqueness of concrete.</p>

Aim/Purpose: The proliferation of fake news through social media threatens to undercut the possibility of ascertaining facts and truth. This paper explores the use of ancient rhetorical tools to identify fake news generally and to see through the misinformation juggernaut of President Donald Trump. Background: The ancient rhetorical appeals described in Aristotle’s Rhetoric—ethos (character of the speaker), pathos (nature of the audience) and logos (message itself)—might be a simple, yet profound fix for the era of fake news. Also known as the rhetorical triangle and used as an aid for effective public speaking by the ancient Greeks, the three appeals can also be utilized for analyzing the main components of discourse. Methodology: Discourse analysis utilizes insights from rhetoric, linguistics, philosophy and anthropology in in order to interpret written and spoken texts. Contribution This paper analyzes Donald Trump’s effective use of Twitter and campaign rallies to create and sustain fake news. Findings: At the point of the writing of this paper, the Washington Post Trump Fact Checker has identified over 10,000 untruths uttered by the president in his first two years of office, for an average of eight untruths per day. In addition, analysis demonstrates that Trump leans heavily on ethos and pathos, almost to the exclusion of logos in his tweets and campaign rallies, making spectacular claims, which seem calculated to arouse emotions and move his base to action. Further, Trump relies heavily on epideictic rhetoric (praising and blaming), excluding forensic (legal) and deliberative rhetoric, which the ancients used for sustained arguments about the past or deliberations about the future of the state. In short, the analysis uncovers how and ostensibly why Trump creates and sustains fake news while claiming that other traditional news outlets, except for FOX news, are the actual purveyors of fake news. Recommendations for Practitioners: Information systems and communication practitioners need to be aware of the ways in which the systems they create and monitor are vulnerable to targeted attacks of the purveyors of fake news. Recommendation for Researchers: Further research on the identification and proliferation of fake news from a variety of disciplines is needed, in order to stem the flow of misinformation and untruths through social media. Impact on Society: The impact of fake news is largely unknown and needs to be better understood, especially during election cycles. Some researchers believe that social media constitute a fifth estate in the United States, challenging the authority of the three branches of government and the traditional press. Future Research: As noted above, further research on the identification and proliferation of fake news from a variety of disciplines is needed, in order to stem the flow of misinformation and untruths through social media.

Much of the Hong Kong landscape consists of densely vegetated steep hillside and may give the impression of natural terrain untouched by man-made activities. However, much evidence of old human activities occurs in our vegetated landscape. The old lead mine workings in the Lin Ma Hang district of the northeast New Territories form a significant industrial heritage site now hidden by dense vegetation. Extensive old anthropogenic activities are seen in site reconnaissance. Most of the man-made features were formed during the mining period (1860-1960) and the WWII (1941-45) occupation of the mine site. Some features have more obscure origins associated with cycles of agricultural activity and settlement of more than 1000 years. The unique and diverse nature of the Lin Ma Hang hillsides provides an ideal case study to demonstrate the benefits of systematic assessment of anthropogenic features in Natural Terrain Hazard Assessment. Some of these man-made features may create impacts as potential adverse Hillside Pocket scenarios and require inventory and classification during natural terrain hazard and other geotechnical studies (Ho & Roberts, 2016). Over the past decade, the application of airborne LiDAR data for site characterization has grown significantly, in part due to advances in handling of very large data sets. Through 3D topographic models using LiDAR in combination with visual data, landforms are revealed and terrain classification is enhanced allowing identification of anthropogenic features of varying scale and origin within their geomorphological setting. The authors discuss the application of a digitally aided approach for terrain mapping with emphasis on the identification and classification of anthropogenic features based on size, type, origin, material, extent and location. These are classified within a Hong Kong-based framework of an 80 class classification following from Styles & Law (2012).

Modern macroeconomics focuses on the identification of the primitive exogenous forces generating business cycles. This is at odds with macroeconomic forecasts collected through surveys, which are about endogenous variables. To address this divorce, our paper uses a general equilibrium model as a multivariate filter to infer the shocks behind market analysts' forecasts and thus, unravel their implicit macroeconomic stories. By interpreting all analysts' forecasts through the same lenses, it is possible to understand the differences between projected endogenous variables as differences in the types and magnitudes of shocks. It also allows to explain market's uncertainty about the future in terms of analysts' disagreement about these shocks. The usefulness of the approach is illustrated by adapting the canonical SOE semi-structural model in Carabenciov et al. (2008a) to Colombia and then using it to filter forecasts of its Central Bank's Monthly Expectations Survey during the COVID-19 crisis.

A systemic approach to identifying road locations that exhibit safety problems was provided by the Safety Needs Identification Program (SNIP and SNIP2) developed by the Purdue University Center for Road Safety (CRS). The new version SNIP Light has been developed to provide other uses with planning level traffic safety analysis capability for a wider range of uses including Metropolitan Planning Agencies (MPOs) who want the tool for planning cost-effective safety programs in their metropolitan areas. The SNIP Light reduces the demand of computing and data storage resources and replaces the SQL server database system an integrated module coded in-house which is considerably faster than the original component. Furthermore, certain proficiency required to install and use the old version is no longer needed thanks to the intuitive single-window interface and executing file operations in the background without the user’s involvement. Some operations, such as optimizing funding of safety projects, are removed to simplify the tool.

We revisit an old question but with a new identification strategy, namely the difference in exchange rate effects between announced (“vocal”) and secret (“dirty”) foreign exchange intervention. Using a Regression Discontinuity Design, we exploit a rule-based intervention mechanism enacted by the Central Bank of Colombia that, under observable and deterministic conditions, triggered either the issuance of FX options or the ability to exercise them. We take the former (issuance) as central bank announcements under a sharp setting, since the rule and information that triggered the issuance of options was public, and we take the latter (exercise) as secret trades under a fuzzy setting, since traders could have chosen (but were not required) to exercise their options in the following days after issuance. Our results indicate that, unconditionally, both announcements and secret trades carry similar effects. However, the effects of announcements are considerably amplified conditional on: (i) higher central bank credibility, (ii) less frequent announcements, and (iii) episodes of higher FX volatility.

Hybridization of Back cross is one method to get varieties that are resistant to downy mildew. The purpose of this study was to obtain information on inheritance characteristics of downy mildew resistance. This research was conducted at the experiment center of Agro-Technology Study Program of Agriculture Faculty, University of Trunojoyo Madura. Research of Assessment of resistance to Downy Mildew used a randomized block design with 18 treatments (P1, P2, F1, F2, BC1P1 and BC1P2 in three sets of crosses, namely LGL x Mdr-3, T12 x Mdr-1 and E02 x Mdr-2) and three replications so there were 54 experimental units. Identification of polymorphic RAPD markers for endurance to downy mildew through Bulk Segregant Analysis (BSA) was done by amplifying the DNA in the resistant pool and susceptible pool. The random primers used were 120 primers from 6 operon groups, namely OPA, OPB, OPC, OPD, OPF and OPG. The results showed that the inheritance pattern of maize genetic resistance to downy mildew followed a segregation pattern of 3:1 with a degree of dominance between -1 and 0, and was controlled by incomplete partially negative dominant gene. OPC-07 was a marker that was linkage close to the resistance to downy mildew with a genetic distance of 1.9 cM.
