Experiment and Modeling of Wireless-Powered Sensor Network

In this paper, we provide a comprehensive system model of a wireless-powered sensor network (WPSN) based on experimental results on a real-life testbed. In the WPSN, a sensor node is wirelessly powered by the RF energy transfer from a dedicated RF power source. We define the behavior of each component comprising the WPSN and analyze the interaction between these components to set up a realistic WPSN model from the systematic point of view. Towards this, we implement a real-life and full-fledged testbed for the WPSN and conduct experiments to obtain model parameters.
Fan Support of Sport Teams: The Effect of a Common Group Identity

Previous research in sport psychology has shown a connection between fan support of sport teams and overall team success by focusing on factors that influence the frequency of fan attendance. The present study examined the impact of fan identification as another determinant of fan support that may operate independent of structural factors such as win-loss record or actual fan attendance. College undergraduates (N=120) completed a survey of student activities that contained measures of collective esteem and ingroup identification in terms of their university affiliation. Subjects indicated the number of games attended and provided evaluations of the university's basketball and football teams. Results indicated that aspects of collective group identity significantly predict fan support in terms of attendance and overall evaluation of both sport teams. Also, level of group identification predicted attitudinal support of teams regardless of actual fan attendance. Implications for the connection of fan identit.
Explaining the International Criminal Court: A ‘Practice Test’ for Rationalist and Constructivist Approaches

Unlike other articles on the International Criminal Court (ICC) that focus on the question of the court’s future effectiveness, this article seeks to explain the creation of the court and its institutional design as established in its statute. It applies theoretical arguments from the rationalist and constructivist literature on international institutions to the ICC case; and demonstrates how both theoretical perspectives can be combined in different ways. The ICC’s establishment can be explained with rationalist arguments focusing on cooperation problems and transaction cost, yet a constructivist view can ‘deepen’ the argument by explaining the perception of problems, and provide an alternative argument focusing on legitimacy concerns. Regarding institutional design, rationalist theory helps identify a tradeoff between a weak court backed by the US and a strong court without US support; a complementary constructivist approach can explain why states opted for the latter.
- 1-A novel intranasal mouse model for mucosal colonisation of 1 Streptococcus suis serotype 2 2 3 Running Title : Intranasal

37 38 Streptococcus (S.) suis causes meningitis and various other diseases in pigs and 39 humans. Healthy piglets carrying virulent S. suis strains on their mucosal surfaces 40 are epidemiologically very important. The objective of this study was to establish an 41 intranasal S. suis mouse model for invasion and colonisation of the respiratory tract. 42 CD1 mice were intranasally infected with a highly virulent S. suis serotype 2 strain 43 under different conditions. Clinical, histological and bacteriological screenings 44 revealed that invasion of host tissue occurred in the majority of mice only after 45 predisposition with 12.5 μl 1 % acetic acid per nostril. Severe fibrinosuppurative or 46 purulent necrotizing pneumonia associated with S. suis was a common 47 manifestation. Furthermore, a novel model to study nasopharyngeal colonisation was 48 established by reducing the volume of 1 % acetic acid per nostril to 5 μl prior S. suis 49 application. This model mimics asymptomatic carriage in swine as all mice carried S. 50 suis on their respiratory mucosa 7 days post infection in moderate to high numbers 51 without development of pneumonia or any other invasive S. suis disease. This 52 intranasal S. suis model was applied to investigate the function of suilysin in 53 colonisation. Though an isogenic suilysin mutant was isolated from the upper 54 respiratory tract at a lower recovery rate than its wild type parental strain 14 days 55 post infection, differences were not significant and did not indicate severe attenuation 56 in colonisation. In conclusion, this work describes the first intranasal mice model to 57 study colonisation of the respiratory tract by a highly virulent S. suis pathotype. 58 59
Genetic Disruption of Cortical Interneuron Development Causes Region- and GABA Cell Type-Specific Deficits, Epilepsy, and Behavioral Dysfunction

The generation of properly functioning circuits during brain development requires precise timing of cell migration and differentiation. Disruptions in the developmental plan may lead to neurological and psychiatric disorders. Neocortical circuits rely on inhibitory GABAergic interneurons, the majority of which migrate from subcortical sources. We have shown that the pleiotropic molecule hepatocyte growth factor/scatter factor (HGF/SF) mediates interneuron migration. Mice with a targeted mutation of the gene encoding urokinase plasminogen activator receptor (uPAR), a key component in HGF/SF activation and function, have decreased levels of HGF/SF and a 50% reduction in neocortical GABAergic interneurons at embryonic and perinatal ages. Disruption of interneuron development leads to early lethality in most models. Thus, the long-term consequences of such perturbations are unknown. Mice of theuPAR−/− strain survive until adulthood, and behavior testing demonstrates that they have an increased anxiety state. TheuPAR−/− strain also exhibits spontaneous seizure activity and higher susceptibility to pharmacologically induced convulsions. The neocortex of the adultuPAR−/− mouse exhibits a dramatic region- and subtype-specific decrease in GABA-immunoreactive interneurons. Anterior cingulate and parietal cortical areas contain 50% fewer GABAergic interneurons compared with wild-type littermates. However, interneuron numbers in piriform and visual cortical areas do not differ from those of normal mice. Characterization of interneuron subpopulations reveals a near complete loss of the parvalbumin subtype, with other subclasses remaining intact. These data demonstrate that a single gene mutation can selectively alter the development of cortical interneurons in a region- and cell subtype-specific manner, with deficits leading to long-lasting changes in circuit organization and behavior.
A semiempirical model for wakeup time estimation in power-gated logic clusters

Wakeup time is an important overhead that must be determined for effective power gating, particularly in logic clusters that undergo frequent mode transitions for run-time leakage power reduction. In this paper, a semiempirical model for virtual supply voltage in terms of basic parameters of the power-gated circuit is presented. Hence a closed-form expression for estimation of wakeup time of a power-gated logic cluster is derived. Experimental results of application of the model to ISCAS85 benchmark circuits show that wakeup time may be estimated within an average error of 16.3% across 22× variation in sleep transistor sizes and 13× variation in circuit sizes with significant speedup in computation time compared to SPICE level circuit simulations.
“The Paper that you Have in Your Hand is My Freedom”: Migrant Domestic Work and the Sponsorship (Kafala) System in Lebanon

A recent report on migrant domestic work in Lebanon has cited psychological disorder among Lebanese “Madams” as the leading cause of violence against their migrant maids (Jureidini, 2011, www.kafa.org.lb/StudiesPublicationPDF/PRpdf38.pdf). This report typifies much of the existing scholarship on the experiences of migrant domestic workers (MDWs) in the Middle East, where the focus is on employer–employee relationships, especially the abusive Arab “Madam. ” In this paper, I argue that the portrayal of violations of MDW rights as abuse of one set of women by another is inherently problematic on several fronts. It privatizes the structural problem of workers’ and immigrant rights violations, delegates it to the household, and absolves the state of its responsibility. Moreover, the focus on abusive employers takes attention away from the root of the problem – the inherently exploitative system of migration and recruitment in the region, the sponsorship system. The sponsorship system not only creates conditions for much of these violations, but also systematically produces a new population of readily exploitable worker – the category of “illegal workers. ” Oral histories and interviews with individual workers are employed to analyze the process by which illegal workers are “produced” in Lebanon. Finally, focus group discussions highlight critical policy recommendations made by the workers themselves, which address the systemic bases of their exploitation in Lebanon.
THE IMPACT OF SEXUAL HISTORY AND DESIRED RELATIONSHIP DURATION ON EVALUATIONS OF ATTRACTIVENESS AND RECALL

Abstract Although there exists a plethora of studies on the determinants and consequences of facial attractiveness, there exists little research on how within-individual evaluations of facial attractiveness are impacted by knowledge of a person's sexual history and the duration of the relationship they seek. Using a pre-post design, participants rated individual faces for attractiveness, and then re-evaluated the faces accompanied by a fictitious online dating advertisement, manipulated for the models’ sexual history and desired relationship duration. We found that women, more than men, were impacted by this knowledge and that desired relationship duration influences the direction of change while sexual history influences the significance of the effect. One week later, participants were presented with the same faces and asked to recall the prior information. Participants recalled more information for sexual history than for desired relationship duration with an overall mean accuracy of 64.4%. These findin.
Screening for postpartum depression. An antepartum questionnaire.

OBJECTIVE To develop and evaluate a questionnaire used antepartum to screen for postpartum depression. STUDY DESIGN Demographic and clinical data, based on previously identified variables, were obtained from 106 second-trimester gravidas (sample I) by interview, self-administered questionnaire and medical record review. The Beck Depression Inventory (BDI) was administered at 1, 6 and 12 weeks postpartum (PP). Statistical analysis, including stepwise linear regression with maximum r-squared improvement, identified a subset of the 24 most predictive variables. This antepartum questionnaire (APQ) was validated retrospectively in the original sample and prospectively in a second group of 99 women (sample II). RESULTS In both sample populations the APQ had acceptable sensitivity (80-82%) and specificity (78-82%). The incidence of postpartum depressive symptoms (PPDS) rose from 10% to 17% by six weeks without an appreciable decline at 12 weeks (15%). The percentage of women showing more than mild depressive symptoms increased with PP time from 30% at 1 week to 47% at 12. CONCLUSION The APQ is now available for screening and evaluating early therapeutic intervention in PPDS.
Biliary cholesterol secretion by the twinned sterol half-transporters ABCG5 and ABCG8.

The long wait for a cellular and functional definition of canalicular transporters for biliary cholesterol appears to be over. Articles in this issue of the JCI provide a fascinating account of the cellular itinerary of two murine ATP-binding cassette (ABC) half-transporters from the ribosome to the hepatocyte apical membranes (1) and show that the corresponding human genes, when overexpressed in transgenic mice, can greatly augment cholesterol secretion into bile (2). This field was opened with the genetic solution (3, 4) to the enigma of a disease commonly known as sitosterolemia (5, 6). This autosomal recessive disorder of lipid metabolism is characterized by an accumulation of plant sterols, including sitosterol, in the plasma of patients with this disease and is therefore also known as phytosterolemia. Normally, the intestinal absorption of sitosterol and other unwanted plant sterols is dwarfed by the absorption of cholesterol, and the absorbed phytosterols are cleared from the body by highly efficient secretion into bile (5). However, patients with sitosterolemia display intestinal hyperabsorption of plant sterols and impaired biliary sterol secretion, leading to accumulation of phytosterols in the body (6). The metabolism of cholesterol is altered in the same manner, but to a lesser extent (5), rendering many patients hypercholesterolemic (6) and prone to xanthomas and premature atherosclerosis (5, 6). The dramatic consequences of this rare disease demonstrate the importance of a finely tuned mechanism for restricting the absorption and accumulation of ingested sterols. The underlying pathophysiological defects indicated that unraveling the molecular basis of sitosterolemia might shed light on important principles concerning intestinal sterol absorption as well as cholesterol secretion into bile. Two independent groups (3, 4) identified mutations in sitosterolemia patients in either member of an adjacent pair of genes, ABCG5 and ABCG8, encoding ABC transporters expressed in the liver and intestine (3, 4, 7). Functional ABC transporters consist of 12 membrane-spanning domains and two ATP-binding sites, whereas ABCG5 and ABCG8 are examples of half-transporters containing only six transmembrane domains and one ATP-binding site. Therefore, both teams of investigators (3, 7) suggested that ABCG5 and ABCG8 function as a heterodimer to limit intestinal sterol absorption by effluxing sterols from enterocytes to small intestinal lumen and by promoting hepatic sterol secretion into bile. Still, in the absence of direct evidence, the function of ABCG5 and ABCG8 and their subcellular localization remained hypothetical until now.
Developmental expression of the chick four‐jointed homologue

Four‐jointed is a type II transmembrane protein that is thought to be cleaved to give rise to a secreted protein. In Drosophila, four‐jointed controls outgrowth, vein patterning, and bristle polarity in the developing limb together with the polarity of the ommatidia in the developing eye. In Drosophila and mice, Fj is regulated by notch signaling. Here, we have determined the expression of the chick four‐jointed (fjx) homologue during embryonic development. We show that fjx is expressed in the limb bud; facial primordia; the proliferating zone of the lens, feather buds, the neural tube; and neural crest derivatives such as the dorsal root ganglia. Analysis of the fjx expression in the developing limb bud showed that initially fjx is expressed throughout the limb bud, but as the limb develops, highest levels of fjx transcripts are found distally. However, by stage 27, fjx expression is predominantly found in the central core of the limb bud. Finally, fjx expression becomes confined to the developing tendons, ligaments, articular cartilage, and arteries but not the veins. Comparison with scleraxis (scx), a marker of tendons and ligaments, revealed that they are coexpressed in the majority of tendons but that fjx is expressed after scx, when the tendons have begun to differentiate. These data suggest that fjx has two roles during limb development: the first controlling outgrowth and the second tissue differentiation.

A Preference-Based Restaurant Recommendation System for Individuals and Groups . Team Size : 3

Using Yelp data, we built a restaurant recommendation system for individuals and groups. For each of 4.9k individual Yelp users, we create a ranking SVM model with features encompassing users’ food preferences and dietary restrictions, such as cuisine type, services o↵ered, ambience, noise level, average rating, etc. Our recommendation system for individual users achieved 72% average prediction accuracy. We propose a metric that maximizes minimum happiness across a group of users, as an alternative to other group recommendation systems where the most commonly recommended restaurant across individual users is selected.
A Survey on Image Steganography Techniques

Steganography is an important technique for information hiding in any digital object. Steganography technique is the science that includes communicating secret information in an appropriate digital multimedia cover objects such as audio, video and image files. The main objective of steganography is to hide the existence of the embedded data. Steganography technique has improved the security of existing data hiding techniques by the outstanding development in computational power. Objectives of steganography are Undetectability, robustness and capacity of the concealed data, these key factors that separate it from related techniques like cryptography and watermarking. This paper delivers a survey on digital images steganography and covering its fundamental concepts. The development of image steganographic methods in spatial representation, in JPEG format and also discuss the recent development in the field of image steganography. Specific generally used approaches for increasing steganographic security are summarized and significant research developments are also discussed.
Protective effect of Tribulus terrestris L. fruit aqueous extracton lipid profile and oxidative stress in isoproterenol induced myocardial necrosis in male albino Wistar rats

The objective of the present study was to evaluate the possible protective effects of Tribulus terrestris fruit aqueous extract (TTFAEt) on lipid profile and oxidative stress in isoproterenol (ISO) induced myocardial necrosis in albino Wistar rats. Albino Wistar rats were divided into normal control, TTFAEt alone treated, ISO control and pretreated (TTFAEt+ISO) groups. The extract was administered at a dose of 50 mg/kg body weight for 40 days orally by gavage and ISO was administered at a dose of 85 mg/kg body weight for two consecutive days intraperitoneally at an interval of 24 h. ISO induced myocardial infarction (MI) was confirmed by disturbances in serum lipid profile, heart tissue lipid peroxidation and antioxidant enzyme levels. There was a significant increase in the levels of serum total cholesterol (32.60 %), triglycerides (41.30 %), very low density lipoproteins (81.81 %), low density lipoproteins (84%) and phospholipids (38.88 %) and a significant decrease in the levels of high density lipoproteins (33.33 %) in the ISO control group when compared to normal controls. Additionally, there is a significant decrease in the levels of heart tissue antioxidant enzymes such as superoxide dismutase, catalase, glutathione reductase, glutathione peroxidase and depletion of reduced glutathione, which indicates enhanced lipid peroxidation(172 %). Pretreatment with extract significantly showed a protective effect against ISO altered lipid profile, lipid peroxidation and antioxidant enzyme levels. The present study showed therapeutic effect of TTFAEt on lipid profile and oxidative stress in isoproterenol (ISO) induced myocardial necrosis in experimental rats.
THE RECLASSIFICATION OF PFIESTERIA SHUMWAYAE (DINOPHYCEAE): PSEUDOPFIESTERIA, GEN. NOV. 1

Pfiesteria shumwayae Glasgow et Burkholder is assigned to a new genus Pseudopfiesteria gen. nov. Plate tabulation differences between Pfiesteria and Pseudopfiesteria gen. nov. as well as a maximum likelihood phylogenetic analysis based on rDNA sequence data warrant creation of this new genus. The Kofoidian thecal plate formula for the new genus is Po, cp, X, 4′, 1a, 6′′, 6c, PC, 5+s, 5′′′, 0p, 2′′′′. In addition to having six precingular plates, P. shumwayae comb. nov. also has a distinctive diamond or rectangular‐shaped anterior intercalary plate. Both Pfiesteria and Pseudopfiesteria gen. nov. are reassigned to the order Peridiniales based on an apical pore complex (APC) with a canal (X) plate that contacts a symmetrical 1′, four to five sulcal plates, and the conservative hypothecal tabulation of 5′′′, 0p, and 2′′′′. These morphological characters and the life histories of Pfiesteria and Pseudopfiesteria are consistent with placement of both genera in the Peridiniales. Based on the plate tabulations for P. shumwayae, P. piscicida, and the closely related “cryptoperidiniopsoid” and “lucy” groups, the family Pfiesteriaceae is amended to include species with the following tabulation: 4‐5′, 0‐2a, 5‐6′′, 6c, PC, 5+s, 5′′′, 0p, and 2′′′′ as well as an APC containing a pore plate (Po), a closing plate (cp), and an X plate; the tabulation is expanded to increase the number of sulcal plates and to include a new plate, the peduncle cover (PC) plate. Members of the family have typical dinoflagellate life cycles characterized by a biflagellated free‐living motile stage, a varying number of cyst stages, and the absence of multiple amoeboid stages.
Detection of double-compression for applications in steganography

This paper presents a method for detection of double JPEG compression and a maximum likelihood estimator of the primary quality factor. These methods are essential for construction of accurate targeted and blind s teganalysis methods for JPEG images. The proposed methods use support vector machine classifiers with feature vectors formed by histograms of low-frequency DCT coefficients. The performance of the algorithms is compared to prior art on a database containing approximately1, 200, 000 images.
Sexual problems, communication patterns, and depressive symptoms in couples coping with metastatic breast cancer

The treatment of breast cancer tends to result in physical side effects (e.g., vaginal dryness, stomatitis, and atrophy) that can cause sexual problems. Although studies of early‐stage breast cancer have demonstrated that sexual problems are associated with increased depressive symptoms for both patients and their partners, comparatively little is known about these associations in metastatic breast cancer (MBC) and how patients and partners cope together with sexual problems. We examined the links between sexual problems, depressive symptoms, and two types of spousal communication patterns (mutual constructive and demand–withdraw) in 191 couples in which the patient was initiating treatment for MBC.
Shared concepts in group decision making: A model for decisions based on qualitative data

This paper presents a methodology for modelling the process of group decision making based on qualitative data. It is hypothesized that group decisions can be modelled in terms of the sharing and negotiation of the individual construct systems of the group members. Individual construct systems are elicited from each group member prior to the group decision using an open-ended sorting procedure (Canter, Brown & Groat, 1985). The combined construct system of the group is represented using a non-metric multidimensional scaling technique known as Multidimensional Scalogram Analysis (MSA). Each stage of the elicitation and representation of the construct systems is illustrated using a worked example taken from an experimental decision-making group choosing houses for student accommodation. The decision reached by the group is compared to the multidimensional model. The potential of the model for social processes research is discussed.
