Abstract:
The paper presents the idea of defective ground structures for the improvement in the radiation characteristics of the antenna especially in the multi-input multi-output (MIMO) configuration. The proposed antenna model with partially flared out feed system is designed and analyzed with defective ground in both single and array configuration. A T stub is a T shaped stub used in this work with defected ground structure. A T stub is included along with defective ground to enhance the MIMO configuration features. The simulations are carried out on electromagnetic modelling tool and analyzed by measuring the parameters like reflection coefficient, voltage standing wave ratio (VSWR), gain, radiation pattern and current distribution plots. For the fabrication of the proposed antenna these measurements are very important. The antenna is fabricated and validated in terms of S-parameters and VSWR. The proposed results are good agreement with the simulated results. The overall size of the antenna is 24 × 18 x 0.8 mm<sup>3</sup>.

Abstract:
We propose a broadband decoupled antenna pair for 5G mobile terminals. The broadband decoupled design of this antenna pair is based on the characteristic mode theory (CMA) and defective ground structure. First, CMA is applied to obtain the characteristic current distribution of the antenna, then the characteristic current sensitive regions are optimized to make the antenna introduce new modes and obtain a wide bandwidth. After that, an antenna pair is added with defective ground structure to obtain a wideband decoupled antenna pair that has small size and high isolation. Next, an eight-element MIMO antenna system is constructed with the obtained broadband decoupled antenna pair, and a composite decoupling technique consisting of defective ground structure (DGS) and decoupling strip is applied to the two antenna pairs on the same side of the bezel to improve the isolation. The simulation and prototype test results show that the eight-element MIMO antenna with −10 dB bandwidth of 3.28~5.85 GHz mainly covers the N77/N78/N79/WLAN 5 GHz band, and the antenna pair are only 1.6 mm apart with good isolation (−16.7 dB), the ECC is less than 0.01, and it has a good total efficiency at the main operating frequency. Finally, the effect of a user’s hand on the antenna is briefly analyzed to verify the robustness of the proposed MIMO antenna system.

Abstract:
Aperture Coupled Micro-Strip Antenna Design and Analysis A linearly-polarized aperture coupled patch antenna design is characterized and optimized using Agilent ADS antenna simulation software [1]. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation for the design of this antenna and its usefulness in arrays and orthogonally polarized communications. The goal of this thesis is to explore dimension effects on aperture coupled antenna performance, to develop a design and tuning procedure, and to describe performance effects through electromagnetic principles. Antenna parameters examined in this study include the dimensions and locations of the substrates, feed line, ground plane coupling slot, and patch. The operating frequency, input VSWR, percent bandwidth, polarization ratio, and broadside gain are determined for each antenna configuration. The substrate material is changed from RT Duroid (material in nominal ADS design [1]) to FR4 due to lower cost and availability. The operating frequency is changed from 2.3GHz (specified in nominal HFSS design) to 2.4GHz for wireless communication applications. Required dimensional adjustments when changing substrate materials and operating frequencies for this antenna are non-trivial and the new design procedure is used to tune the antenna. The antenna is fabricated using 59mil thick double and single sided FR4 boards joined together with double sided 45mil thick acrylic tape. The antenna is characterized in an anechoic chamber and experimental results are compared to theoretical predictions.

Abstract:
Consider a large population containing a small number of defective items. A commonly encountered goal is to identify the defective items, for example, to isolate them. In the classical non-adaptive group testing (NAGT) approach, one groups the items into subsets, or pools, and runs tests for the presence of a defective itemon each pool. Using the outcomes the tests, a fundamental goal of group testing is to reliably identify the complete set of defective items with as few tests as possible. In contrast, this thesis studies a non-defective subset identification problem, where the primary goal is to identify a “subset” of “non-defective” items given the test outcomes. The main contributions of this thesis are: We derive upper and lower bounds on the number of nonadaptive group tests required to identify a given number of non-defective items with arbitrarily small probability of incorrect identification as the population size goes to infinity. We show that an impressive reduction in the number of tests is achievable compared to the approach of first identifying all the defective items and then picking the required number of non-defective items from the complement set. For example, in the asymptotic regime with the population size N → ∞, to identify L nondefective items out of a population containing K defective items, when the tests are reliable, our results show that O _ K logK L N _ measurements are sufficient when L ≪ N − K and K is fixed. In contrast, the necessary number of tests using the conventional approach grows with N as O _ K logK log N K_ measurements. Our results are derived using a general sparse signal model, by virtue of which, they are also applicable to other important sparse signal based applications such as compressive sensing. We present a bouquet of computationally efficient and analytically tractable nondefective subset recovery algorithms. By analyzing the probability of error of the algorithms, we obtain bounds on the number of tests required for non-defective subset recovery with arbitrarily small probability of error. By comparing with the information theoretic lower bounds, we show that the upper bounds bounds on the number of tests are order-wise tight up to a log(K) factor, where K is the number of defective items. Our analysis accounts for the impact of both the additive noise (false positives) and dilution noise (false negatives). We also provide extensive simulation results that compare the relative performance of the different algorithms and provide further insights into their practical utility. The proposed algorithms significantly outperform the straightforward approaches of testing items one-by-one, and of first identifying the defective set and then choosing the non-defective items from the complement set, in terms of the number of measurements required to ensure a given success rate. We investigate the use of adaptive group testing in the application of finding a spectrum hole of a specified bandwidth in a given wideband of interest. We propose a group testing based spectrum hole search algorithm that exploits sparsity in the primary spectral occupancy by testing a group of adjacent sub-bands in a single test. This is enabled by a simple and easily implementable sub-Nyquist sampling scheme for signal acquisition by the cognitive radios. Energy-based hypothesis tests are used to provide an occupancy decision over the group of sub-bands, and this forms the basis of the proposed algorithm to find contiguous spectrum holes of a specified bandwidth. We extend this framework to a multistage sensing algorithm that can be employed in a variety of spectrum sensing scenarios, including non-contiguous spectrum hole search. Our analysis allows one to identify the sparsity and SNR regimes where group testing can lead to significantly lower detection delays compared to a conventional bin-by-bin energy detection scheme. We illustrate the performance of the proposed algorithms via Monte Carlo simulations.

Abstract:
Prejudiced beliefs may certainly seem like defective beliefs. But in what sense defective? No doubt, many of them will be false. Some will also be harmful. But many philosophers further argue that prejudiced belief is defective also in the sense that it could only arise from distinctive kinds of epistemic irrationality: we could acquire or retain our prejudiced beliefs only by culpably violating our epistemic responsibilities. Moreover, it is assumed that we are morally responsible for the harms that our prejudiced beliefs cause only because, in forming these beliefs in the first place, we are violating our epistemic responsibilities. This book argues that these common convictions are false and misguided. It shows in detail that there can be plenty of epistemically justified pathways to prejudiced belief. Moreover, it argues that it is a mistake to lean on the concept of epistemic responsibility to give content to ethical responsibilities. In particular, this would unreasonably burden victims of prejudice with having to show that their victimizers were in a position to know better. Accordingly, this book develops an account of moral responsibility for harm which does not depend on finding grounds for epistemic blame. In support of this view, the book offers a number of examples and case studies at individual, collective, and institutional levels of decision making. Additionally, it develops a systematic platform for “non-ideal epistemology” which would apply also to a wide range of other socio-epistemic phenomena of current concern, such as fake news, conspiracy theories, science scepticism, and more.

Abstract:
This chapter proposes a theory of moral regression, arguing that inclusivist gains can be eroded not only if certain harsh biological and social conditions indicative of out-group threat actually reappear but also if significant numbers of people come to believe that such harsh conditions exist even when they do not. It argues that normal cognitive biases in conjunction with defective social-epistemic practices can cause people wrongly to believe that such harsh conditions exist, thus triggering the development and evolution of exclusivist moralities and the dismantling of inclusivist ones. Armed with detailed knowledge of the biological and social environments in which progressive moralities emerge and are sustained, as well as the conditions under which they are likely to be dismantled, human beings can take significant steps toward transforming the classic liberal faith in moral progress into a practical, empirically grounded hope.

Duncan, Fairgrieve, and Richard Goldberg. Product Liability. Oxford University Press, 2020. http://dx.doi.org/10.1093/oso/9780199679232.001.0001.

Full text
Abstract:
Product Liability is a recognised authority in the field and covers the product liability laws through which manufacturers, retailers, and others may be held liable to compensate persons who are injured, or who incur financial loss, when the products which they manufacture or sell are defective or not fit for their purpose. Product defects may originate in the production process, be one of design, or be grounded in a failure to issue an adequate warning or directions for safe use and practitioners advising business clients or claimants will find this book provides all the necessary information for practitioners to manage a product liability claim. This new edition has been fully updated to take account of 10 years of development in case law and regulation, and the increasing impact of cross-border and transnational sale of goods. The Court of Justice of the European Union handed down major rulings concerning the Product Liability Directive which affect the application of the Directive and national arrangements and Fairgrieve and Goldberg examines this in detail. For any legal practitioner operating in areas which require knowledge of European product liability law, an understanding of the impact of recent developments is essential and this work is an essential resource for practitioners working on product liability, sale of goods, personal injury and negligence. The work provides comprehensive coverage of the law of negligence as it applies to product liability, of the strict liability provisions of the Consumer Protection Act 1987, and of the EU's Product Liability Directive on which the Act is based. Although the majority of cases involve pharmaceuticals and medical devices, in recent English cases the allegedly defective products have been as diverse as a child's buggy, an All Terrain Vehicle, and even a coffee cup. Many cases are brought as group actions, and the book examines the rights of those who are injured by defective products. As well as considering the perspective of the law as it has developed in the UK, this edition contains detailed discussion of case law from other jurisdictions including the USA, Australia, New Zealand, Canada, France and Germany. The coverage in the work is complemented by a full analysis of issues which arise in transnational litigation involving problems of jurisdiction and the choice of laws.

Defective lipid catabolic pathways are involved in numerous inherited metabolic diseases such as lysosomal storage diseases and peroxisome biogenesis disorders. We recently described a new classification of a rapidly growing group of inherited metabolic disorders involving biosynthesis and remodeling of complex lipids including phospholipids and sphingolipids. The remarkable progress achieved over the last decade in high throughput gene sequencing and in lipid analysis technologies have enabled the description of more than 40 diseases linked to defects in enzymes involved in these pathways. Some of these defects present in infancy or childhood but most of them are diagnosed in adolescence or adulthood. In this review we focus on those with adult presentation.

Abstract:
This chapter discusses the various ways in which defectors came across the front line. Scenarios varied. Some defectors came as part of organized desertions of entire units; more came in small groups; and about just as many came alone. The front line could be overcome simply by letting it pass, a particularly viable option in 1941, but also possible later in the war; others exploited holes in the front, used planes or tanks to get across, or absconded after having been sent across the line in an attack or a commando operation. Often, defection was a violent process, which required sometimes deadly force against superiors or compadres. The chapter describes these scenarios and puts the moment of defection into a larger framework of the wartime trajectories of men who ended up surrendering.

Abstract:
The institution or asylum in North America was established as a mechanism for confining, controlling, and containing groups of individuals classified and labeled as mentally ill or intellectually disabled and defined as deviant, defective, or delinquent. These congregate facilities, established both for the protection of the individuals housed there and for the simultaneous protection of society from those same people, developed into massive structures designed to accommodate thousands of residents/patients/inmates. The rationale behind the rapid rise of the institution throughout the nineteenth and into the mid-twentieth centuries paralleled the growth of modern medicine and psychiatry. By the 1950s, institutions housed hundreds of thousands of individuals. Yet by the start of the twenty-first century, the institutional model had been intellectually discredited, and these facilities had been all but abandoned. This rather astounding demise mirrored broader social, scientific, and medical trends.

Full text
Abstract:
Oligosaccharidoses are a group of lysosomal diseases, also called glycoproteinoses, biochemically characterized by storage of protein-bound oligosaccharides within lysosomes and excretion with urine of corresponding sugars. Storage of oligosaccharides results from absence or defective function of a specific lysosomal enzyme. Classification includes α‎ and β‎ mannosidosis, fucosidosis, sialidosis types I and II, Schindler disease, and aspartylglycosaminuria. Galactosialidosis characterized by deficiency of β‎-galactosidase and α‎-neuraminidase with presence in patient urine of oligosaccharides has been included among oligosaccharidoses but may be better classified as a lysosomal enzyme protection defect disease in relation to its primary defect of cathepsine A-protective protein. The clinical spectrum of the diseases vary widely, as is common in lysosomal storage disorders. Patients frequently have neurological symptoms, but in rare cases presenting in adulthood symptoms may be very subtle. Psychiatric presentations have been described in adults. For adult cases, no treatments are available except for supportive care.

Abstract:
AbstractIn graphic and industrial printing applications inkjet technologies are gaining attention and market coverage. Beside some key success factors as scalability there is an inherent difficulty of temporally or permanent defective/non operating nozzles. These non working nozzle have a severe impact on printed quality. Several approaches are known to reduce these artefacts. One is to use multi-pass printing, sometimes in combination with the use of defect nozzle information. Another is to detect these nozzles direct or indirect and use for example so called reserve nozzles. A predecessor thereof is the detection of pen lines (Beauchamp et al (1992) Hewlett-Packard J 12:35–41). In multi-nozzle systems individual or groups of nozzles are addressed to fire using a matrix scheme. This method reduces the number of used address lines.Here an automated working scheme is sketched to firstly identify defect nozzles using a sample print by means of a dedicated pattern. A digital picture taken by scan or camera is the basis of an image analysis procedure afterwards. Secondly it is shown that, once the matrix configuration is known, possible defects of the address lines may be identified too. Finally a pattern dedicated to a specific print head is introduced to check the later fact visually.

Abstract:
As Gurgaon expands horizontally and vertically, it continues to transition from farms to urban villages to a concrete maze. This photographic project documents the growth of Gurgaon a city recently developed near India's capital, Delhi. It is a booming financial and industrial center, home to most Multinational Corporations (MNCs) and has third highest per-capita income in India. As its advocates often like to point out, Delhi’s booming neighbor has 1,100 high-rises, at least 30 malls and thousands of small and big industries. On the other hand, as its detractors unfailingly like to note, the dust bowl’s population has grown two and a half fold, it has 12-hour power blackouts, and its groundwater would probably not last beyond this decade. Gurgaon's transformation began sometime around 1996, with the advent of Genpact, then a business unit of General Electric. Other multinational companies followed it slowly thereafter. It helped that the city was a few kilometers away from Delhi. Two decades on, Gurgaon is already "on its deathbed." From 0.8 million in 2001, the city is expected to reach a population of 6.9 million in 2031. It is speckled with glass buildings with curtain walls, and swish apartment blocks with Greco-Roman influences, but there is little water or power for them. These numbers alone don’t capture the lived reality of Gurgaon, though. The skyline that its older residents were accustomed to has completely disappeared. And yet on the periphery, one sees the "Unfinished City" growing. The landscapes and flora shouting; their sentiments brutalized by evictions and concrete. Slaughtered farms now seem witness to monstrosity with desolate faces and fading memories. Set in 2014 the project explores the ephemerality of Gurgaon’s glamor and defective town planning. Families had been displaced, laborers’ children were growing up on heaps of cement, and farmlands had turned into things of memories.

Abstract:
This was an exploratory one-year study to identify chemical regulators of the COP9 signalosome. Chemical Genetics uses small molecules to modify or disrupt the function of specific genes/proteins. This is in contrast to classical genetics, in which mutations disrupt the function of genes. The underlying concept is that the functions of most proteins can be altered by the binding of a chemical, which can be found by screening large libraries for compounds that specifically affect a biological, molecular or biochemical process. In addition to screens for chemicals which inhibit specific biological processes, chemical genetics can also be employed to find inhibitors of specific protein-protein interactions. Small molecules altering protein-protein interactions are valuable tools in probing protein-protein interactions. In this project, we aimed to identify chemicals that disrupt the COP9 signalosome. The CSN is an evolutionarily conserved eight-subunit protein complex whose most studied role is regulation of E3 ubiquitinligase activity. Mutants in subunits of the CSN undergo photomorphogenesis in darkness and accumulate high levels of pigments in both dark- and light-grown seedlings, and are defective in a wide range of important developmental and environmental-response pathways. Our working hypothesis was that specific molecules will interact with the CSN7 protein such that binding to its various interacting proteins will be inhibited. Such a molecule would inhibit either CSN assembly, or binding of CSN-interacting proteins, and thus specifically inhibit CSN function. We used an advanced chemical genetic screen for small-molecule-inhibitors of CSN7 protein-protein interactions. In our pilot study, following the screening of ~1200 unique compounds, we isolated four chemicals which reproducibly interfere with CSN7 binding to either CSN8 or CSN6.

Abstract:
Brucella Mutagenesis (TAMU) The working hypothesis for this study was that survival of Brucella vaccines was directly related to their persistence in the host. This premise is based on previously published work detailing the survival of the currently employed vaccine strains S19 and Rev 1. The approach employed signature-tagged mutagenesis to construct mutants interrupted in individual genes, and the mouse model to identify mutants with attenuated virulence/survival. Intracellular survival in macrophages is the key to both reproductive disease in ruminants and reticuloendothelial disease observed in most other species. Therefore, the mouse model permitted selection of mutants of reduced intracellular survival that would limit their ability to cause reproductive disease in ruminants. Several classes of mutants were expected. Colonization/invasion requires gene products that enhance host-agent interaction or increase resistance to antibacterial activity in macrophages. The establishment of chronic infection requires gene products necessary for intracellular bacterial growth. Maintenance of chronic infection requires gene products that sustain a low-level metabolism during periods characterized little or no growth (1, 2). Of these mutants, the latter group was of greatest interest with regard to our originally stated premise. However, the results obtained do not necessarily support a simplistic model of vaccine efficacy, i.e., long-survival of vaccine strains provides better immunity. Our conclusion can only be that optimal vaccines will only be developed with a thorough understanding of host agent interaction, and will be preferable to the use of fortuitous isolates of unknown genetic background. Each mutant could be distinguished from among a group of mutants by PCR amplification of the signature tag (5). This approach permitted infection of mice with pools of different mutants (including the parental wild-type as a control) and identified 40 mutants with apparently defective survival characteristics that were tentatively assigned to three distinct classes or groups. Group I (n=13) contained organisms that exhibited reduced survival at two weeks post-infection. Organisms in this group were recovered at normal levels by eight weeks and were not studied further, since they may persist in the host. Group II (n=11) contained organisms that were reduced by 2 weeks post infection and remained at reduced levels at eight weeks post-infection. Group III (n=16) contained mutants that were normal at two weeks, but recovered at reduced levels at eight weeks. A subset of these mutants (n= 15) was confirmed to be attenuated in mixed infections (1:1) with the parental wild-type. One of these mutants was eliminated from consideration due to a reduced growth rate in vitro that may account for its apparent growth defect in the mouse model. Although the original plan involved construction of the mutant bank in B. melitensis Rev 1 the low transformability of this strain, prevented accumulation of the necessary number of mutants. In addition, the probability that Rev 1 already carries one genetic defect increases the likelihood that a second defect will severely compromise the survival of this organism. Once key genes have been identified, it is relatively easy to prepare the appropriate genetic constructs (knockouts) lacking these genes in B. melitensis Rev 1 or any other genetic background. The construction of "designer" vaccines is expected to improve immune protection resulting from minor sequence variation corresponding to geographically distinct isolates or to design vaccines for use in specific hosts. A.2 Mouse Model of Brucella Infection (UWISC) Interferon regulatory factor-1-deficient (IRF-1-/- mice have diverse immunodeficient phenotypes that are necessary for conferring proper immune protection to intracellular bacterial infection, such as a 90% reduction of CD8+ T cells, functionally impaired NK cells, as well as a deficiency in iNOS and IL-12p40 induction. Interestingly, IRF-1-/- mice infected with diverse Brucella abortus strains reacted differently in a death and survival manner depending on the dose of injection and the level of virulence. Notably, 50% of IRF-1-/- mice intraperitoneally infected with a sublethal dose in C57BL/6 mice, i.e., 5 x 105 CFU of virulent S2308 or the attenuated vaccine S19, died at 10 and 20 days post-infection, respectively. Interestingly, the same dose of RB51, an attenuated new vaccine strain, did not induce the death of IRF-1-/- mice for the 4 weeks of infection. IRF-1-/- mice infected with four more other genetically manipulated S2308 mutants at 5 x 105 CFU also reacted in a death or survival manner depending on the level of virulence. Splenic CFU from C57BL/6 mice infected with 5 x 105 CFU of S2308, S19, or RB51, as well as four different S2308 mutants supports the finding that reduced virulence correlates with survival Of IRF-1-/- mice. Therefore, these results suggest that IRF-1 regulation of multi-gene transcription plays a crucial role in controlling B. abortus infection, and IRF-1 mice could be used as an animal model to determine the degree of B. abortus virulence by examining death or survival. A3 Diagnostic Tests for Detection of B. melitensis Rev 1 (Kimron) In this project we developed an effective PCR tool that can distinguish between Rev1 field isolates and B. melitensis virulent field strains. This has allowed, for the first time, to monitor epidemiological outbreaks of Rev1 infection in vaccinated flocks and to clearly demonstrate horizontal transfer of the strain from vaccinated ewes to unvaccinated ones. Moreover, two human isolates were characterized as Rev1 isolates implying the risk of use of improperly controlled lots of the vaccine in the national campaign. Since atypical B. melitensis biotype 1 strains have been characterized in Israel, the PCR technique has unequivocally demonstrated that strain Rev1 has not diverted into a virulent mutant. In addition, we could demonstrate that very likely a new prototype biotype 1 strain has evolved in the Middle East compared to the classical strain 16M. All the Israeli field strains have been shown to differ from strain 16M in the PstI digestion profile of the omp2a gene sequence suggesting that the local strains were possibly developed as a separate branch of B. melitensis. Should this be confirmed these data suggest that the Rev1 vaccine may not be an optimal vaccine strain for the Israeli flocks as it shares the same omp2 PstI digestion profile as strain 16M.
