Abstract:
Transportation of cattle to the slaughter plant could influence hide contamination with Salmonella enterica. Fecal and hide samples were obtained from 40 lots of cattle at the feedlot and again at the slaughter plant. Potential risk factors for hide contamination were evaluated. A multilevel Poisson regression model was used to determine whether transportation and lairage were associated with hide contamination by Salmonella. Cattle with hide samples positive for Salmonella at the feedlot had twice the risk of having positive slaughter hide samples compared with cattle without positive feedlot hide samples (relative risk [RR], 1.9). Cattle transported in trailers from which samples positive for Salmonella were collected had twice the risk of having positive slaughter hide samples compared with cattle transported in culture-negative trailers (RR, 2.3). Cattle transported for long distances had twice the risk of having positive hide samples at slaughter compared with cattle transported shorter distances (RR, 2.3). Cattle held in lairage pens contaminated with feces had twice the risk of having positive slaughter hide samples compared with cattle held in clean pens (RR, 1.8). Cattle held off feed longer than 18 h before loading had twice the risk of having positive slaughter hide samples compared with cattle held off feed for shorter times (RR, 1.7). Cattle that were agitated during loading had twice the risk of having positive slaughter hide samples compared with cattle that were calm (RR, 2.2). These findings suggest that variables associated with transportation and lairage can impact the presence of Salmonella on the hides of cattle at slaughter.

Abstract:
ABSTRACT The putative source of hide contamination for 236 cattle in Scotland followed from the farm through to slaughter was determined using phage and verocytotoxin type data. The majority of cattle (84%) were found to have subtypes of Escherichia coli O157 on their hide that had not been found previously in any animal from the farm of origin, strongly suggesting that contamination occurred once animals had left the farm of origin. Using logistic regression analysis, several variables and factors were found to be strongly associated (P < 0.01) with cross-contamination of cattle hides at the univariate level; commercial transport to slaughter, transport with other animals, use of a crush, line automation, and increasing slaughterhouse throughput were all risk factors, while feeding hay in lairage, processing an animal earlier in a slaughter cohort, and cleaning the landing area poststunning were protective. In the multivariable model, with the slaughterhouse and the farm group included as random effects, factors associated with the cross-contamination of cattle hides were identified. Transport to the slaughterhouse by a commercial hauler had a borderline-significant association with increased odds of an animal having a cross-contaminated hide (odds ratio [OR] [95% confidence interval {CI}] = 5.7 [0.99, 33.0]; P = 0.05). At the slaughterhouse, providing hay to cattle waiting in lairage (OR [95% CI] = 0.04 [<0.01, 1.04]; P = 0.05) and cleaning the landing area (OR [95% CI] = 0.03 [<0.01, 1.15,]; P = 0.06) also had a borderline-significant association with decreased odds of an animal having a cross-contaminated hide. Although the prevalence of carcass contamination remains very low, targeted intervention at the preslaughter stage may have the potential to reduce further the risk to public health.

Abstract:
Hide et al . (Hide, Skeldon & Acheson 1996 Proc. R. Soc. A 452 , 1369–1395) introduced a nonlinear system of three coupled ordinary differential equations to model a self-exciting Faraday disk homopolar dynamo. A very small selection of its possible behaviours was presented in that paper. Subsequent studies have extended the system to incorporate the effects of a nonlinear motor, an external battery and magnetic field, the coupling of two or more identical dynamos together, among other things. In this paper, we return to the original model with a view to perform a more extensive analysis of the Hide et al . dynamo. For the first time, we present bifurcation transition diagrams, so that the two examples of chaotic dynamo action (shown in figure 9 in that paper) can now be placed into context. We exhibit the coexistence of multiple attractors and also identify the lowest order unstable periodic orbits pertaining to some specific cases.

Abstract:
Transportation of cattle from the feedlot to the slaughter plant could influence hide contamination of Escherichia coli O157. A study was initiated to investigate the influence of transportation and lairage on shedding and hide contamination of E. coli O157. Fecal and hide samples were obtained from 40 pens of harvest-ready beef cattle at the feedlot prior to transport and again at the slaughter plant immediately after slaughter. Potential risk factors for hide contamination at the feedlot, during transport, and at slaughter were evaluated. A multilevel Poisson regression model was used to evaluate if transportation and lairage were associated with hide contamination by E. coli O157 in finished beef cattle. Lots of cattle held in E. coli O157–positive lairage pens had eight times greater risk of having positive slaughter hide samples compared with cattle held in culture-negative pens (relative risk, 8.0; 95% confidence interval, 1.6 to 38.8). Lots of cattle that were held in lairage pens contaminated with feces had three times greater risk for positive slaughter hide samples compared with cattle held in clean pens (relative risk, 3.1; 95% confidence interval, 1.2 to 7.9). Lots of cattle that were transported for long distances (&gt;160.9 km) had twice the risk of having positive hide samples at slaughter compared with cattle transported a shorter distance (relative risk, 2.4; 95% confidence interval, 1.1 to 5.1). These findings suggest that transportation and lairage should be considered in E. coli O157 control strategies.

Abstract:
A total of 123 steers of six European breeds (Angus, Simmental, Charolais, Limousin, Blonde d'Aquitaine, Piedmontese) were used (i) to evaluate the precision of the ultrasound-predicted intramuscular fat (USIMF) and its sources of variation using the current Pie QUIP technology and (ii) to develop improved models for predicting USIMF. Steers were slaughtered when they reached the target value of 3.5% USIMF. Hide samples were obtained 3 d before slaughter by shot-biopsy. After slaughter, a sample of the longissimus muscle was used to determine actual chemical intramuscular fat (EEIMF), collagen content and solubility. Among the variables available during a chute-side scanning session, hide thickness and ultrasound subcutaneous fat thickness at the 12th and 13th ribs were shown to be significantly correlated with EEIMF. These two variables were selected as possible independent variables to evaluate the construction of new models. The model with the best fit included USIMF, hide thickness and liveweight and had a standard error of prediction of 0.96%, which is similar to other published technologies. Breed group and collagen-related traits did not influence USIMF estimation. Finally, the revised Pie QUIP technology should be considered as one technology of choice to predict EEIMFcontent in live animals.

Abstract:
The hides of cattle are the primary source of pathogens such as Escherichia coli O157:H7 that contaminate preevisceration carcasses during commercial beef processing. A number of interventions that reduce hide contamination and subsequent carcass contamination are currently being developed. The objective of this study was to determine the efficacy of ozonated and electrolyzed oxidizing (EO) waters to decontaminate beef hides and to compare these treatments with similar washing in water without the active antimicrobial compounds. Cattle hides draped over barrels were used as the model system. Ozonated water (2 ppm) was applied at 4,800 kPa (700 lb in2) and 15°C for 10 s. Alkaline EO water and acidic EO water were sequentially applied at 60°C for 10 s at 4,800 and 1,700 kPa (250 lb in2), respectively. Treatment using ozonated water reduced hide aerobic plate counts by 2.1 log CFU/100 cm2 and reduced Enterobacteriaceae counts by 3.4 log CFU/100 cm2. EO water treatment reduced aerobic plate counts by 3.5 log CFU/100 cm2 and reduced Enterobacteriaceae counts by 4.3 log CFU/100 cm2. Water controls that matched the wash conditions of the ozonated and EO treatments reduced aerobic plate counts by only 0.5 and 1.0 log CFU/100 cm2, respectively, and each reduced Enterobacteriaceae counts by 0.9 log CFU/100 cm2. The prevalence of E. coli O157 on hides was reduced from 89 to 31% following treatment with ozonated water and from 82 to 35% following EO water treatment. Control wash treatments had no significant effect on the prevalence of E. coli O157:H7. These results demonstrate that ozonated and EO waters can be used to decontaminate hides during processing and may be viable treatments for significantly reducing pathogen loads on beef hides, thereby reducing pathogens on beef carcasses.

Abstract:
The ability to correctly judge moral character—an individual’s disposition to think, feel, and behave ethically—is critical considering the negative consequences of misjudgment (e.g., being betrayed or swindled). However, it is currently unknown whether people can reliably detect strangers’ moral character, nor is it known how to best elicit relevant information from strangers to determine their moral character. This research is designed to remedy this dearth in our understanding of moral character judgments, particularly in settings where we need to make prompt evaluations of strangers based on limited information that we obtained from them. The biggest challenge in assessing another person’s moral character is that it is extremely socially desirable, and therefore highly susceptible to distorted self-perceptions and impression management. To address this problem, I propose and test a new person-perception theory: the hidden information distribution and evaluation (HIDE) model. In chapter 1, I develop the HIDE model, which posits that there are aspects of information that individuals do not correctly know about themselves (which I call the hiddenself), as well as aspects of information individuals misrepresent to others (which I call the hiding-self). This model articulates when and why judges (i.e., evaluators) not personally acquainted with targets of evaluation (e.g., job applicants) can reliably detect these targets’ moral character and predict their future unethical behavior. In particular, I propose that the impromptu thinking and language usage that arises when a person answers specially designed interview questions reveal information about his/her hidden-self and hiding-self, enabling a group of judges to make valid judgments about his/her moral character. Additionally, the HIDE model predicts that judges’ evaluations using this written interview method will be more valid than evaluations provided by targets’ acquaintances. This is because social relationships can lead people to form biased impressions of targets they are acquainted with, so that they are unable to see the targets’ hidden selves as clearly as judges who do not know the targets. In chapter 2, I test the HIDE model’s prediction that groups of judges can reliably predict targets’ unethical behavior by evaluating their moral character using the written interview method. In studies 1 and 2, large groups of judges were crowd-sourced online. I show that their average moral character evaluations successfully predicts targets’ frequency of unethical behaviors in the laboratory (study 1) and the workplace (study 2). Study 3 extends these findings by determining the minimum number of judges (six) required to make moral character evaluations that predict unethical behavior. In chapter 3, I test the HIDE model’s prediction that judges’ evaluations based on the written interview method can capture unique information about targets’ hidden-self. Three empirical studies (studies 4, 5, and 6) show that these evaluations indeed capture unique variance in targets’ moral character that is missed by both self-reports and ratings provided by targets’ acquaintances. Consequently, these evaluations are more predictive of targets’ unethical behavior than the ratings provided by either the targets themselves or their acquaintances. In chapter 4, I investigate the HIDE model’s prediction that judges’ evaluations using the written interview method can capture unique information about targets’ hiding-self. This occurs because responses to the interview questions reveal implicit aspects of moral character that targets cannot control or fake, even when they want to. In study 7, I manipulated whether targets had an incentive to answer the interview questions in a positively biased manner. I show that judges’ evaluations of targets (based on the interview questions) are actually more predictive of their unethical behavior when targets were motivated to respond in a positively biased manner. Finally, in chapter 5, I carried out text analyses to explore how human judges utilize linguistic cues in written responses to form impressions of moral character, and how these cues predict targets’ unethical behavior. The goal of this chapter is to identify linguistic cues that human judges fail to correctly detect or utilize, and thus to identify shared biases in human perceptions of ethicality. Building on these exploratory text analyses, I discuss the future directions of this research program, especially the potential value of combining human judgments and machine algorithms to boost the accuracy of unethical behavior forecasts.

Abstract:
Tracking of a single ground target using GMTI radar detections is considered. A Variable Structure- Autonomous- Interactive Multiple Model (VS-A-IMM) structure is developed to address challenges of ground target tracking, while maintaining an acceptable level computational complexity at the same time. The following approach is used in this thesis: Use simple tracker structures
incorporate a priori information such as topographic constraints, road maps as much as possible
use enhanced gating techniques to minimize the eect of clutter
develop methods against stop-move motion and hide motion of the target
tackle on-road/o-road transitions and junction crossings
establish measures against non-detections caused by environment. The tracker structure is derived using a composite state estimation set-up that incorporate multi models and MAP and MMSE estimations. The root mean square position and velocity error performances of the VS-A-IMM algorithm are compared with respect to the baseline IMM and the VS-IMM methods found in the literature. It is observed that the newly developed VS-A-IMM algorithm performs better than the baseline methods in realistic conditions such as on-road/o-road transitions, tunnels, stops, junction crossings, non-detections.

Mestrado em Biotecnologia - Alimentar
Honey is essentially composed by carbohydrates, fructose (38 %) and glucose (31 %), mainly resultant of invertase activity. Furthermore, several oligosaccharides can be identified in honey, comprising 5 to 10 % of total carbohydrates. The origin of these oligosaccharides is still uncertain, as most of them are not present neither in nectar or in pollen. The research on this subject, mainly conducted in the past century, demonstrated the capability of invertase, namely the α-glucosidase activity, to transfer α-glucosyl residues to other carbohydrate moieties. As this transglucosylation activity was reported both to bees’ and honey’s invertases, it was proposed that the action of invertase was the source for α-glucose linked sugars. Nonetheless, there is still no explanation for the origin of the remaining oligosaccharides. The present work hypothesizes that nonenzymatic reactions could also occur in honey promoting the formation of oligosaccharides. This can be supported by the fact that honey maturation conditions, such as high sugar concentrations in acidic media, induce condensation of carbohydrates, reactions also known as reversion reactions. In order to validate this hypothesis, six aqueous model solutions (moisture content of 20 %) containing sucrose plus glucose, and sucrose plus fructose were prepared using diluted citric acid at pH 4.0, pH 2.0, and with no acid addition. The model solutions were kept in an oven at 35 ⁰C, which is the normal temperature inside beehives with brood production. Besides the influence of honey maturation conditions on its oligosaccharides profile was assessed by analysis of honeys with different properties, particularly the duration and season of maturation. Electrospray ionization mass spectrometry (ESI-MS) analysis allowed monitoring the changes occurring in each model solution along 5 months. This method revealed the occurrence of non-enzymatic oligosaccharide synthesis with a degree of polymerization (DP) up to 6 after 5 months. Ligand-exchange/size-exclusion chromatography (LEX-SEC) separation of the oligosaccharides formed in model solutions and present in honey and methylation analysis allowed to observe that the produced oligosaccharides had a glycosidic linkage composition similar to that obtained for honey oligosaccharides. In higher amounts, for most fractions, were terminally-linked glucose (Glc) residues together with lower amounts of (1->2)-, (1->4)- and (1->6)-Glc. Concerning fructose, terminally-linked fructose (Fru) residues were the most abundant and (2->1)- and (2->6)-Fru were in minor amounts. In addition, several branched residues were identified, being (1->2,3,4,6)-Glc the most abundant, and found predominantly in solutions prepared with citric acid. The structure and identity of the oligosaccharides were further elucidated by gas-chromatography coupled to mass-spectrometry (GC-MS) after derivatization to the alditol acetates derivatives.
O mel é composto essencialmente por hidratos de carbono, sendo a frutose (38 %) e a glucose (31 %) maioritariamente resultantes da atividade da invertase. Além disso, vários oligossacarídeos foram identificados no mel, constituindo 5 a 10 % do total dos açúcares. A origem destes oligossacarídeos ainda é incerta, uma vez que a maioria não é reportada nem no néctar nem no pólen. A investigação desta temática, maioritariamente conduzida no século passado, demonstraram a capacidade da invertase, designadamente a atividade de α-glucosidase, em transferir resíduos α-glucosyl para grupos funcionais de outros hidratos de carbono. Uma vez que esta atividade de transglucosilação foi reportada tanto para a invertase das abelhas como do mel, especulou-se que a ação desta enzima estivesse na origem dos açúcares com ligações de α-glucose. No entanto, ainda não existe uma explicação para a origem dos restantes oligossacarídeos. O presente trabalho coloca a hipótese de que reações não enzimáticas possam ocorrer no mel, promovendo a formação de oligossacarídeos. Esta hipótese pode ser suportada pelo facto das condições de maturação do mel, como as concentrações elevadas de açúcar em meio ácido, induzirem à condensação dos hidratos de carbono, reações também designadas por reações de reversão. De forma a validar esta hipótese, seis soluções modelo aquosas (teor de humidade de 20 %) de sacarose com glucose e de sacarose com frutose foram preparadas com ácido cítrico diluído a pH 4.0, a pH 2.0 e sem adição de ácido. As soluções foram mantidas numa estufa a 35⁰C, correspondente à temperatura média no interior da colmeia aquando da criação do ninho. Também se acedeu à influência das condições de maturação do mel no seu perfil de oligossacarídeos, através da análise de méis com diferentes propriedades, destacando-se a duração e o tempo de maturação. As análises de ionização em electrospray acopladas a espectrometria de massa (ESI-MS) permitiram monitorizar as alterações que ocorreram nas soluções durante 5 meses. Este método revelou a ocorrência da síntese de oligossacarídeos não enzimática, com um DP máximo observado de 6, após 5 meses. A separação dos açúcares formados nas soluções modelo e presentes nos méis através de cromatografia de afinidade e de exclusão-molecular (LEX-SEC) e a análise de metilação permitiram observar que os oligossacarídeos produzidos tinham uma composição em ligações glicosídicas semelhante à dos oligossacarídeos do mel. A maioria das frações era composta principalmente por resíduos de glucose ligados pelo terminal e por resíduos de fructose ligada terminalmente e, em menor quantidade, por resíduos de glucose com ligações (1->2), (1->4) e (1->6) e por resíduos de frutose com ligações (2->1), (2->3) e (2->6). Também foram identificados resíduos correspondentes a ramificações, sendo o (1->2,3,4,6) -Glc o mais abundante e encontrado predominantemente em soluções elaboradas com ácido cítrico. A estrutura e a identidade dos oligossacarídeos anteriormente mencionados foram clarificados através da cromatografia gasosa acoplada à espectrometria de massa, após derivatização nos seus acetatos de alditol.

Abstract:
The High-Intensity-Discharge Lamps (HID), consisting of a broad range of gas discharge lamps, are notable for their high luminous efficacy, good color rendering, and long life. Metal halide lamps have the best combination of the above properties and are considered the most ideal light sources. Recently, there has been an emerging demand to replace the conventional halogen headlamps with the newly introduced small-wattage metal halide HID lamps. However, this lamp demands a highly efficient ballast and very complex control circuitry that can achieve fast turn-on and different regulation modes during the lamp start-up process. Due to the complex lamp v-i profile and timing control requirements, control circuit built with conventional analog control is unavoidably cumbersome. With the unparalleled flexibility and programmability, digital control shows more advantages in this application. An automotive HID ballast with digital controller is developed to demonstrate the feasibility of the digital control along with some key issues in digital controller selection and design. Results show that the microcontroller-based HID ballast can successfully realize the required control functions and achieve a smooth turn-on process and a fast turn-on time of 8 seconds. One of the major issues of ballast design is the ballast/HID lamp system stability, which originates from the lamp negative incremental impedance. The lamp small-signal model is presented with simulation and measurements. The negative incremental impedance is attributed to a RHP zero in the small-signal model. A new analysis approach, impedance ratio criterion, is proposed to analyze the system stability. With this approach, it clearly shows how the control configurations and converter and control design affect the system stability. The results can provide guidance and be easily used in control configuration selection and converter and control design. Analysis shows that ballast based on PWM converter without inner current loop is unstable and with inner current loop can stabilized the system. This is the reason why for a microcontroller-based ballast system the inner current loop has to be used. HID lamp has its special acoustic resonance problem and thus a low-frequency unregulated full-bridge is used following the front-end DC/DC converter. To prevent from lamp re-igniting during each bridge commutation, a minimum current changing slope has to be guaranteed. In order to help design the converter, the ballast/lamp re-ignition analysis is presented. With this analysis, it shows that the output capacitance has to be small enough to ensure adequate current slope during zero crossing. Though some approximation is used to simplify the analysis, the results can provide qualitative guidance in the ballast design.

Abstract:
The aim of the study was to better understand the business model change process at the firm level with specific reference to small firms, an area that remains under researched. Business model change drivers, constraints and facilitators were examined in the context of small, independent videogame development firms. The videogame industry is a fast-moving, global industry with entrepreneurial characteristics and a notable number of small and micro firms involved in games development. Such firms have traditionally operated using a contractor-based, ‘work-for-hire’ business model. This is characterised by project-based activities, little or no proprietary intellectual property, a weak financial model, and limited possibilities to build value into the firm. In recent years, new market and technology-related opportunities have emerged for such firms to change to a higher value model that incorporates proprietary intellectual property ownership, an ‘IP’ model. However despite the attraction of this model, and support from industry and policymakers, the successful change from work-for-hire has been limited thereby restricting both firm and industry development. Understanding the rationale for this can contribute to the business model change literature and inform videogame industry policy. This was an empirical study incorporating an exploratory, inductive approach with an embedded single case design that focused on independent videogame development firms and four business model change routes. Qualitative, longitudinal data were collected via 37 semi-structured interviews with purposefully selected entrepreneurs and industry experts; personal observations from interviews and 13 industry events in the UK and abroad; and documentation analysis of firm and industry data. The key findings indicated that: (i) business model change drivers were internal and external in nature with the entrepreneur’s preferences and the business model characteristics being dominant; (ii) certain business model change constraints influenced the composition, timing and success of business model change but were rarely preventative at business model adoption; (iii) the change process was opportunistic, ad hoc and facilitated by experimentation, finance, parallel models and a supportive firm and external environment; and (iv) parallel models were a critical part of business model change. For industry the study indicated that: (i) the IP model opportunity is questionable for many firms; (ii) the work-for-hire and combination models were prevalent but underrated; and (iii) innovation at the business model component may be a more appropriate way for videogame development firms to gain value.

Abstract:
Målet med den här datorbaserade filosofiska utredningen inom kognitionsvetenskap är att utforska intentionalitet i kollektiva beteenden hos artificiella svärmar. Två definitioner av intentionalitet utforskades; som representationer hos agenter och som observerbara attribut hos agenter, även kallat intentional stance. För den representativa definitionen användes en modell av kollektiv intentionalitet som integrerar två olika ståndpunkter, singularståndpunkten och pluralståndpunkten av kollektiv intentionalitet. Modellen har fem villkor för intentionalitet enligt SharedPlans. Genom att använda Belief-Desire-Intention-modellen för intelligenta agenter operationaliserades villkoren till möjliga representationer. En implementation av en målinriktad artificiell svärm i NetLogo analyserades genom att studera hur väl den uppfyllde de operationaliserade villkoren. Fyra av fem villkor var uppfyllda. Flera simuleringar med olika hastighet genomfördes även under observation. Dessa visade att processen kunde delas upp i tre faser med olika egenskaper. Den utforskande fasen hade gemensam intentionalitet centrerad till ett fåtal aktiva individer. Beslutsfasen hade individuella intentioner som kunde stå i konflikt med varandra medan gemensamma intentioner strävade mot samma mål. I flyttfasen var de individuella intentionerna att förhålla sig till varandra, vilket fick gruppen att upplevas som en enhet med intentionen att flytta gruppen. Resultaten visade att intentionalitet kan observeras och analyseras hos den här artificiella svärmen. Däremot har svärmen inte kollektiv intentionalitet utifrån båda ståndpunkterna.

Abstract:
One way to use the ‘wisdom of crowds’ is to look at past judgements and aggregate them. We take as our model courts, which often follow a norm of respecting precedents (‘stare decisis’). The problem, however, with complete deference to past judgements is the emergence of informational cascades. If all judges respect tradition, a situation arises in which everyone sets their own private information to the side and blindly follows the majority judgement of past decisions. Possible solutions are to hide precedents, or to have some judges who are ‘stubborn’ in refusing to follow precedent, or to have some judges who only aggregate informative precedents. But these solutions involve judges not following tradition. Looking beyond courts, we caution against epistemic arguments from traditionalism more generally.

Abstract:
This chapter looks at subjects’ concealed misbehavior in research. When their personal interests conflict with the demands of participation, some subjects put their own interests first. They don’t follow study requirements and try to hide this fact from researchers. In rejecting the restrictions research imposes, subjects diminish the value of research results. They create risks to themselves and others; they also disregard ethical responsibilities to adhere to research agreements and tell the truth. At the same time, rule-breaking subjects expose ethical problems in the design and conduct of clinical trials. Features of the research environment create fertile ground for concealed rule-breaking. Intensified policing and guidance are two common strategies for reducing subject misbehavior, but collaborative reforms are more consistent with the partnership model of clinical research.

Abstract:
The wage of an individual is observed only when he/she is employed. However, getting employment requires two decisions. First, an individual has to decide to participate in the labour market, and second, an employer must decide to hire that individual. Since female labour market participation often differs from that of men, and employers’ decisions to hire may also be influenced by gender, it is appropriate to account for this double selection process. This study uses the latest household survey in Ghana to estimate gender wage gaps by correcting for this double selection process. We find that the average total gender wage gap is positive and significant irrespective of the sample selection correction method used. Our results indicate that women on average receive lower wages than men. Irrespective of the type of selection method used, our findings suggest that almost all the wage gap is a result of differences in returns, with only a small part coming from differences in observables. We find that the gender wage gap is smaller among formal wage employees and the gap decreases as education level increases. Although our findings indicate a similar trend in the wage gap across all specifications, the magnitude of the gap is sensitive to the choice of the model. This points to the need to be cautious about the choice of sample selection correction used to analyse gender wage gaps.

Abstract:
AbstractHypoxic ischaemic encephalopathy (HIE) is a significant cause of death and disability. Therapeutic hypothermia (TH) is the only available standard of treatment, but 45–55% of cases still result in death or neurodevelopmental disability following TH. This work has focussed on developing a new brain tissue physiology and biochemistry systems biology model that includes temperature effects, as well as a Bayesian framework for analysis of model parameter estimation. Through this, we can simulate the effects of temperature on brain tissue oxygen delivery and metabolism, as well as analyse clinical and experimental data to identify mechanisms to explain differing behaviour and outcome. Presented here is an application of the model to data from two piglets treated with TH following hypoxic-ischaemic injury showing different responses and outcome following treatment. We identify the main mechanism for this difference as the Q10 temperature coefficient for metabolic reactions, with the severely injured piglet having a median posterior value of 0.133 as opposed to the mild injury value of 5.48. This work demonstrates the use of systems biology models to investigate underlying mechanisms behind the varying response to hypothermic treatment.

Abstract In this chapter, we will learn about the buffer abstraction. We learned about Unified Shared Memory (USM), the pointer-based strategy for data management, in the previous chapter. USM forces us to think about where memory lives and what should be accessible where. The buffer abstraction is a higher-level model that hides this from the programmer. Buffers simply represent data, and it becomes the job of the runtime to manage how the data is stored and moved in memory.

Abstract:
AbstractThis is the first multimodal study of cerebral tissue metabolism and perfusion post-hypoxic-ischaemic (HI) brain injury using broadband near-infrared spectroscopy (bNIRS), diffuse correlation spectroscopy (DCS), positron emission tomography (PET) and magnetic resonance spectroscopy (MRS). In seven piglet preclinical models of neonatal HI, we measured cerebral tissue saturation (StO2), cerebral blood flow (CBF), cerebral oxygen metabolism (CMRO2), changes in the mitochondrial oxidation state of cytochrome c oxidase (oxCCO), cerebral glucose metabolism (CMRglc) and tissue biochemistry (Lac+Thr/tNAA). At baseline, the parameters measured in the piglets that experience HI (not controls) were 64 ± 6% StO2, 35 ± 11 ml/100 g/min CBF and 2.0 ± 0.4 μmol/100 g/min CMRO2. After HI, the parameters measured were 68 ± 6% StO2, 35 ± 6 ml/100 g/min CBF, 1.3 ± 0.1 μmol/100 g/min CMRO2, 0.4 ± 0.2 Lac+Thr/tNAA and 9.5 ± 2.0 CMRglc. This study demonstrates the capacity of a multimodal set-up to interrogate the pathophysiology of HIE using a combination of optical methods, MRS, and PET.

Abstract:
In the game of hide and seek, one or more agents (hiders) can hide behind objects to prevent other agents (seekers) from seeing them through their line of sight (visibility). These hider agents can be eventually found by seekers who explore the environment. The hide and seek model serves as an abstraction of many real world scenarios such as police agents trying to capture intruders hiding in a warehouse, security/patrolling agents on the lookout for any suspicious activity, spying drones trying to prevent themselves from being caught. Medusa allows modeling such scenarios by supporting the simulation, visualization and analysis of hider and seeker agent strategies under different environments.

Abstract:
Existing multi-label learning (MLL) approaches mainly assume all the labels are observed and construct classification models with a fixed set of target labels (known labels). However, in some real applications, multiple latent labels may exist outside this set and hide in the data, especially for large-scale data sets. Discovering and exploring the latent labels hidden in the data may not only find interesting knowledge but also help us to build a more robust learning model. In this paper, a novel approach named DLCL (i.e., Discovering Latent Class Labels for MLL) is proposed which can not only discover the latent labels in the training data but also predict new instances with the latent and known labels simultaneously. Extensive experiments show a competitive performance of DLCL against other state-of-the-art MLL approaches.

Abstract:
Large volumes of urban statistical data with multiple views imply rich knowledge about the development degree of cities. These data present crucial statistics which play an irreplaceable role in the regional analysis and urban computing. In reality, however, the statistical data divided into fine-grained regions usually suffer from missing data problems. Those missing values hide the useful information that may result in a distorted data analysis. Thus, in this paper, we propose a spatial missing data imputation method for multi-view urban statistical data. To address this problem, we exploit an improved spatial multi-kernel clustering method to guide the imputation process cooperating with an adaptive-weight non-negative matrix factorization strategy. Intensive experiments are conducted with other state-of-the-art approaches on six real-world urban statistical datasets. The results not only show the superiority of our method against other comparative methods on different datasets, but also represent a strong generalizability of our model.

Full text
Abstract:
Rotating stall is an instability phenomenon that arises in axial flow compressors when the flow is reduced at constant rotational speed. It is characterised by the onset of rotating perturbations in the flow field accompanied by either an abrupt or gradual decrease of performances. Although the flow field is unsteady and non axisymmetric, the global operating point is stable and a stalled branch of performance curve may be experimentally determined. The number, rotational speed, circumferential extension of the rotating perturbed flow regions named rotating cells may vary from one compressor to another and may depend on the throttle position. The present work focuses on the interaction between local flow parameters and global compressor performance parameters with the aim of reaching a better understanding of the phenomenon. Starting from the Day, Greitzer and Cumpsty [1] model the detailed flow conditions during rotating stall are studied and related to the global performance parameters. This is done both to verify if the compressor under examination fits to the model and if the detailed flow structure may highlight the physics that in the simple model may hide behind the correlation’s used.

Abstract:
Distributed algorithms that operate in the fail-recovery model rely on the state stored in stable memory to guarantee the irreversibility of operations even in the presence of failures. The performance of these algorithms lean heavily on the performance of stable memory. Current storage technologies have a defined performance profile: data is accessed in blocks of hundreds or thousands of bytes, random access to these blocks is expensive and sequential access is somewhat better. File system implementations hide some of the perfor- mance limitations of the underlying storage devices using buffers and caches. However, fail-recovery distributed algorithms bypass some of these techniques and perform synchronous writes to be able to tolerate a failure during the write itself. Assuming the distributed system designer is able to buffer the algorithm’s writes, we ask how buffer size and latency complement each other. In this paper we start to answer this question by characterizing the performance (throughput and latency) of typical stable memory devices using a representative set of current file systems.

Abstract:
The current study is focused on thermal radiation interaction with the natural convection of atmospheric brown cloud (ABC). The current study puts emphasis on ultra fine carbon-black particle suspension of several nano meter range along with some pollutant gas mixture with atmospheric air. The numerical simulation of double diffusive thermo-gravitational convection of ABC is done with Hide and Mason laboratory model for atmosphere. The effect of flow circulation is simulated by setting different value of buoyancy ratios. The effect of participating media radiation has been investigated for various values of optical depth. The governing equations, describing circulation of ABC are solved using modified Marker and Cell method. Gradient dependent consistent hybrid upwind scheme of second order is used for discretization of the convective terms. Discrete ordinate method, with S8 approximation is used to solve radiative transport equation. Comprehensive studies on controlling parameters that affect the flow and heat transfer characteristics have been addressed. The results are provided in graphical and tabular form to delineate the flow behavior and heat transfer characteristics.
