Analysis, Insights and Generalization of a Fast Decentralized Relay Selection Mechanism

Relay selection for cooperative communications has attracted considerable research interest recently. While several criteria have been proposed for selecting one or more relays and analyzed, mechanisms that perform the selection in a distributed manner have received relatively less attention. In this paper, we analyze a splitting algorithm for selecting the single best relay amongst a known number of active nodes in a cooperative network. We develop new and exact asymptotic analysis for computing the average number of slots required to resolve the best relay. We then propose and analyze a new algorithm that addresses the general problem of selecting the best Q ≥ 1 relays. Regardless of the number of relays, the algorithm selects the best two relays within 4.406 slots and the best three within 6.491 slots, on average. Our analysis also brings out an intimate relationship between multiple access selection and multiple access control algorithms.
Children's Perceptions of Human Resources in Team-Teaching Classrooms

dren perceive their classmates, their teachers, and other adults? Do older children see others differently than younger children do? Are boys' perceptions the same as girls'? (1). Research on teaching and, indeed, on childhood socialization, has a clear adultcentered bias. Brophy and Good (2) have studied the interaction between individual students and their teachers. These researchers based their work on that of
Functional Zonation of the Adult Mammalian Adrenal Cortex

The standard model of adrenocortical zonation holds that the three main zones, glomerulosa, fasciculata, and reticularis each have a distinct function, producing mineralocorticoids (in fact just aldosterone), glucocorticoids, and androgens respectively. Moreover, each zone has its specific mechanism of regulation, though ACTH has actions throughout. Finally, the cells of the cortex originate from a stem cell population in the outer cortex or capsule, and migrate centripetally, changing their phenotype as they progress through the zones. Recent progress in understanding the development of the gland and the distribution of steroidogenic enzymes, trophic hormone receptors, and other factors suggests that this model needs refinement. Firstly, proliferation can take place throughout the gland, and although the stem cells are certainly located in the periphery, zonal replenishment can take place within zones. Perhaps more importantly, neither the distribution of enzymes nor receptors suggest that the individual zones are necessarily autonomous in their production of steroid. This is particularly true of the glomerulosa, which does not seem to have the full suite of enzymes required for aldosterone biosynthesis. Nor, in the rat anyway, does it express MC2R to account for the response of aldosterone to ACTH. It is known that in development, recruitment of stem cells is stimulated by signals from within the glomerulosa. Furthermore, throughout the cortex local regulatory factors, including cytokines, catecholamines and the tissue renin-angiotensin system, modify and refine the effects of the systemic trophic factors. In these and other ways it more and more appears that the functions of the gland should be viewed as an integrated whole, greater than the sum of its component parts.
Comorbidity of Enuresis in Children With Attention-Deficit/Hyperactivity Disorder

Objective: To compare parental psychopathology and psychiatric disorders in ADHD children with and those without enuresis. Method: The participants of the clinical sample interviewed according to DSM-IV diagnostic criteria were 35 children with ADHD and enuresis, 153 ADHD children without enuresis, 115 fathers, and 172 mothers. Results: Only ODD comorbidity was the predictor of enuresis. Conduct disorder, tic disorder, major depressive disorder, separation anxiety disorder, bruxism, generalized anxiety disorder, obsessive compulsive disorder, and nail biting were not statistically more frequent in ADHD children with enuresis than in the ADHD children without enuresis. The only parental psychiatric disorder that was related to the groups was father’s major depressive disorder. Conclusion: Enuresis in ADHD has a relationship with ODD. Physicians who treat patients with ADHD and enuresis should routinely inquire about the presence of major depression in the fathers. (J. of Att. Dis. 2010; 13(5) 464-467)
Multi-swarm Optimization of a Graphene FET Based Voltage Controlled Oscillator Circuit

The lack of well defined abstraction levels and immature design tools have made the custom design and optimization of analog circuits slow, complex and laborious. Furthermore, CMOS technology beyond 10 nm faces fundamental limits which may restrict its applicability for future devices. In this paper, a Graphene Field Effect Transistor (GFET) based cross-coupled LC circuit is used as case study to design a mixed-signal integrated circuit. A Multi-Swarm Optimization (MSO) algorithm is used for fast exploration of the design space for the GFET based LC-VCO to maximize its operating frequency given phase noise and power dissipation as optimization constraints. The length (L) and width (W) of the graphene channel are selected as the design variables. The phase noise is kept below-80 dBc/Hz and power dissipation is less than 16 mW. The design optimization flow results in a maximum frequency of 2.58 GHz for L = 3.35 μm and W = 1.82 μm and the phase noise and power dissipation constraints are well below the guard limits.
Constructions of Motherhood and Fatherhood in Newspaper Articles on Maternal and Paternal Postpartum Depression

Postpartum depression (PPD) is typically constructed as a medical condition that is defined by prevalence rates, time of onset, duration, symptoms, causes and treatments. Presentations of PPD in popular texts have also revealed that it is a site for constructions of mothering/motherhood. While PPD has traditionally been assumed to be the domain of women, researchers have recently focused attention on PPD and men. Using articles on maternal and paternal PPD published in Canadian and American newspapers between 2008 and 2012, we analysed how constructions of mothering/motherhood and fathering/fatherhood were inscribed in this public forum. We show how mothering/motherhood was foregrounded via dominant evaluative discourses and highly imbued with expectations while fathering/fatherhood was kept in the background and characterised by the unavailability of clear expectations. We conclude that maternal PPD remains primary and normative while paternal PPD remains ‘othered’ despite the supposed attention to it in these public texts.
Annotating gene function by combining expression data with a modular gene network

MOTIVATION A promising and reliable approach to annotate gene function is clustering genes not only by using gene expression data but also literature information, especially gene networks. RESULTS We present a systematic method for gene clustering by combining these totally different two types of data, particularly focusing on network modularity, a global feature of gene networks. Our method is based on learning a probabilistic model, which we call a hidden modular random field in which the relation between hidden variables directly represents a given gene network. Our learning algorithm which minimizes an energy function considering the network modularity is practically time-efficient, regardless of using the global network property. We evaluated our method by using a metabolic network and microarray expression data, changing with microarray datasets, parameters of our model and gold standard clusters. Experimental results showed that our method outperformed other four competing methods, including k-means and existing graph partitioning methods, being statistically significant in all cases. Further detailed analysis showed that our method could group a set of genes into a cluster which corresponds to the folate metabolic pathway while other methods could not. From these results, we can say that our method is highly effective for gene clustering and annotating gene function.

Towards the best points of interpolation using particles swarm optimisation approach

Many studies, mostly empirical, have been devoted to finding optimal choice nodes for interpolating. When exploring the underlying factors that determine what is a good such choice, we are led to consider the Runge phenomenon (RP; best known in case of high order polynomial interpolation) as a key error mechanism. However, we shall see by using PSO that interpolation with polynomials of high degree can be very useful for the obtaining of the estimates of functions. This paper presents the advantage of using the Particle Swarm Optimization (PSO) interpolation nodes. PSO is a technique based on the cooperation between particles. The exchange of information between these particles allows to resolve difficult problems.
When does a digraph admit a doubly stochastic adjacency matrix?

Digraphs with doubly stochastic adjacency matrices play an essential role in a variety of cooperative control problems including distributed averaging, optimization, and gossiping. In this paper, we fully characterize the class of digraphs that admit an edge weight assignment that makes the digraph adjacency matrix doubly stochastic. As a by-product of our approach, we also unveil the connection between weight-balanced and doubly stochastic adjacency matrices. Several examples illustrate our results.
The Temporal Event Graph

Temporal networks are increasingly being used to model the interactions of complex systems. Most studies require the temporal aggregation of edges (or events) into discrete time steps to perform analysis. In this article we describe a static, lossless, and unique representation of a temporal network, the temporal event graph (TEG). The TEG describes the temporal network in terms of both the inter-event time and two-event temporal motif distributions. By considering these distributions in unison we provide a new method to characterise the behaviour of individuals and collectives in temporal networks as well as providing a natural decomposition of the network. We illustrate the utility of the TEG by providing examples on both synthetic and real temporal networks.
The Urban Precariat, Neoliberalization, and the Soft Power of Humanitarian Design

This essay examines the humanitarian design movement's efforts to address the crushing need, social precarity, and ecological frailty that define global megacities. The aims and character of the humanitarian design movement have been shaped by both the ethical demands of antiglobalization struggles and the rise of nongovernmental organizations as a principal means of social service-delivery in the Global South. The emergent humanitarian design movement offers a compelling critique of the failure of mainstream architectural and industrial design practices to address profound human suffering. Champions of humanitarian design, however, offer a technological fix (e.g., life straws, paper log houses, and hippo rollers) for problems rooted in imperial histories and neoliberal restructuring. In failing to address the dynamics of structural underdevelopment, do-good design performs the grassroots ideological work of neoliberalism by promoting market values and autoregulation. Within the humanitarian-corporate complexes, the global poor are construed as objects of elite benevolence and non-profit largesse, rather than as historical subjects possessing their own unique worldviews, interests, and notions of progress. This essay concludes by briefl y sketching an alternative approach to self-determination for the poor where technological development is grounded in egalitarian cultures of anticapitalist social movements.
Prospective teachers’ mental health and their help-seeking behaviours

Objective: Although the teaching profession is stressful and despite the known impact of teachers’ mental health on students during teaching, prospective teachers’ mental health is neglected in training and selection. However, knowledge about teacher candidates’ mental health during their training process and about their help-seeking behavior can contribute to improving their mental health. Therefore, this study aims at determining the mental state of teacher candidates and elucidating help-seeking behaviors that may be useful for overcoming mental problems. Method: Our sample consisted of 724 prospective teachers studying at the Faculty of Education of Canakkale Onsekiz Mart University in Canakkale; 501 (69.2%) were women, 223 (30.8%) were men. Data were collected using the Brief Symptom Inventory (BSI) and a Sociodemographic Data Form prepared by the researchers. Results: At the end of the study, in 40.6% of the prospective teachers a high severity of distress was detected. The most commonly determined mental symptoms were depression and hostility. The teaching candidates had mostly referred to informal sources, but 39.2% had not sought any help. For mental symptoms, they had mostly sought help informally from their mother or father and siblings, and formally from psychologists or psychiatrists. As factors inhibiting help-seeking, assumed inability of understanding, lack of faith in the possibility of help, and fear of being judged by peers, hesitation to accept help and lack of knowledge about where to look were related to mental symptoms. Conclusions: The study shows the necessity to pay attention to prospective teachers’ mental health, promote formal sources, emphasize the role of informal sources like father and siblings, and overcome obstacles in the way of seeking help. It appears that, in the context of prophylactic mental health services, the development of psychological support may be useful in order to increase prospective teachers’ mental health.
G.729 Error Recovery for Internet Telephony

This memorandum discusses the use of the ITU G.729 CS-ACELP speech coder on the Internet for telephony applications. In particular, the memo explores issues of error resiliency and recovery. In particular, the paper considers two questions. First, given N consecutive frame erasures (due to packet losses), how long does the decoder take to resynchronize its state with the encoder? What is the strength of the resulting error signal, both in terms of objective and subjective measures? The second issue explores which particular factors contribute to the strength of the error signal: the distortion of the speech due to the incorrect concealment of the erasures, or the subsequent distortion due to the loss of state synchronization, even though correct packets are being received. Both objective and subjective measures are used to characterize the importance of each of these two factors.
A web-based editor for multiplayer choice games

The structure of a choice-driven interactive story can be modeled as a syntax tree, generated by a player from a grammar, which in turn was generated by a game author. Using this grammar metaphor, “Boswell”, a web-based Integrated Development Environment, was developed for writing, testing, playing and sharing choice-based interactive ﬁction scripts. The system includes a domain-speciﬁc language, a map overview, a parse-tree debugger, and a network client for multiplayer games.
An Investigation of Dose Rate and Source Dependent Effects in 200 GHz SiGe HBTs

We present an investigation of the observed variations in the total dose tolerance of the emitter-base spacer and shallow trench isolation oxides in a commercial 200 GHz SiGe HBT technology. Proton, gamma, and X-ray irradiations at varying dose rates are found to produce drastically different degradation signatures at the various oxide interfaces. Extraction and analysis of the radiation-induced excess base current, as well as low-frequency noise, are used to probe the underlying physical mechanisms. Two-dimensional calibrated device simulations are employed to correlate the observed results to the spatial distributions of carrier recombination in forward- and inverse-mode operation for both pre- and post-irradiation levels. Possible explanations of our observations are offered and the implications for hardness assurance testing are discussed
Assessment of the 10-year risk of cardiovascular disease among a group of patients on maintenance hemodialysis: A cross-sectional study from Cameroon

Objective To assess the 10-year risk of cardiovascular disease and potential impacting factors among patients undergoing hemodialysis in Yaoundé, Cameroon. Design A cross-sectional study in January 2016. Setting Patients were recruited at the dialysis unit of the Yaoundé University Teaching Hospital, Cameroon. Participants These were hemodialysis patients aged 20 years and above, dialyzing in the above unit since at least 3 months and volunteering to be enrolled in the study. Main outcome measures The risk of cardiovascular disease was assessed using the Framingham risk score. Results We included 44 patients. The risk of cardiovascular disease ranged from less than 1% to more than 30% with a median of 12.3% (interquartile range 4.9–24.4). Twenty hemodialysis patients (45.5%) had a low risk of cardiovascular disease (<10%), 10 (22.7%), a moderate risk (10–20%), and 14 (31.8%) presented a high risk of cardiovascular disease (>20%). In multivariable linear regression analysis, duration on dialysis (adjusted β = 0.11; p = 0.003), number of weekly sessions of physical activity (adjusted β = −1.35; p = 0.018), fasting serum glucose levels (adjusted β = 4.22; p = 0.022), serum triglycerides levels (adjusted β = 5.94; p = 0.033), and serum urea levels (adjusted β = −2.08; p = 0.039) were independently impacting our patients’ risk of cardiovascular disease. Conclusion Around 55% of our study population presented a moderate or high risk of cardiovascular disease. Duration on dialysis, number of physical activity sessions per week, fasting serum glucose, serum triglycerides, and serum urea levels may impact our hemodialysis patients’ risk of cardiovascular disease.
Long-run effects of motivation on labor-market success

We examine the relationship between motivation and labor-market success using a sample from the Panel Study of Income Dynamics (PSID). We relate social psychological traits and other characteristics observed in men age 21-29 to labor-market attainments measured 15 to 25 years later. In contrast to most previous work with these and similar national survey data, we find that earnings are affected strongly both by an orientation toward challenge, and by a sense of personal control. The effects of these measures, if anything, increase with the measurement interval between the traits and subsequent earnings. Orientation toward challenge also predicts future on-the-job training. Taken together, our motivational measures are about as powerful as completed schooling in accounting for future labor-market success.
Brain mapping of deception and truth telling about an ecologically valid situation: functional MR imaging and polygraph investigation--initial experience.

PURPOSE To examine the neural correlates during deception and truth telling by using a functional magnetic resonance (MR) imaging technique and an ecologically valid task and to compare the results with those of a standard polygraph examination. MATERIALS AND METHODS All subjects gave written informed consent for this HIPAA-approved study, which was approved by the institutional review board of Drexel University. Eleven healthy subjects (five female and six male subjects; mean age, 28.9 years) were randomly assigned to the group of guilty subjects or the group of nonguilty subjects. Each group consisted of two separate functional MR imaging conditions: "lie-only condition" and "truth-only condition. " The lie-only condition was used to compare brain activity during a known lie to control questions and a subjective lie to relevant questions. The truth-only condition was used to compare brain activity during a known truthful response to control questions and a subjective truthful response to relevant questions. Functional MR images were acquired with an echo-planar sequence, and statistical analysis was performed. Physiologic responses were measured with a standard four-channel polygraph instrument. RESULTS During the deception process, specific areas of the frontal lobe (left medial and left inferior frontal lobes), temporal lobe (right hippocampus and right middle temporal gyrus), occipital lobe (left lingual gyrus), anterior cingulate, right fusiform gyrus, and right sublobar insula were significantly active. During the truth telling process, specific areas of the frontal (left subcallosal gyrus or lentiform nucleus) and temporal (left inferior temporal gyrus) lobes were significantly active. The polygraph examination revealed 92% accuracy in deceptive subjects and 70% accuracy in truthful subjects. CONCLUSION Specific areas of the brain involved in deception or truth telling can be depicted with functional MR imaging.
Inset fed patch antenna with five slots

In the following paper, a rectangular microstrip patch antenna with two main kinds of slots which are rectangular slots that are more frequently used and L shaped slots are designed, simulated, built and tested. Furthermore, a circular-shaped input feed with 1 mm diameter was chosen to feed the antenna from the edge of the inset-fed part of the antenna. Moreover, an RT6002 substrate with 0.76 mm thickness was the raw material of the antenna. Eventually; this design was capable of acheiving a gain of 8.2 dB with a remarkable value of-15.2 dB for S11 in the manufactured antenna, for a Ku band frequency of 14.4 GHz as Vector Network Analyzer measures. As this design has a Ku band frequency, it could be used for satellite communications such as NASA's Tracking Data Relay Satellite, backhauls broadcasting, and vehicle speed detection.
On the Reliability of the surrogate Data Test for nonlinearity in the Analysis of noisy Time Series

In the analysis of real world data, the surrogate data test is often performed in order to investigate nonlinearity in the data. The null hypothesis of the test is that the original time series is generated from a linear stochastic process possibly undergoing a nonlinear static transform. We argue against reported rejection of the null hypothesis and claims of evidence of nonlinearity based on a single nonlinear statistic. In particular, two schemes for the generation of surrogate data are examined, the amplitude adjusted Fourier transform (AAFT) and the iterated AAFT (IAFFT) and many nonlinear discriminating statistics are used for testing, i.e. the fit with the Volterra series of polynomials and the fit with local average mappings, the mutual information, the correlation dimension, the false nearest neighbors, the largest Lyapunov exponent and simple nonlinear averages (the three point autocorrelation and the time reversal asymmetry). The results on simulated data and real data (EEG and exchange rates) suggest that the test depends on the method and its parameters, the algorithm generating the surrogate data and the observational data of the examined process.
