SIMAP: A simplicial-map layer for neural networks

In this paper, we present SIMAP, a novel layer integrated into deep learning models, aimed at enhancing the interpretability of the output. The SIMAP layer is an enhanced version of Simplicial-Map Neural Networks (SMNNs), an explainable neural network based on support sets and simplicial maps (functions used in topology to transform shapes while preserving their structural connectivity). The novelty of the methodology proposed in this paper is two-fold: Firstly, SIMAP layers work in combination with other deep learning architectures as an interpretable layer substituting classic dense final layers. Secondly, unlike SMNNs, the support set is based on a fixed maximal simplex, the barycentric subdivision being efficiently computed with a matrix-based multiplication algorithm.
Localized Construction of Connected Dominating Set in Wireless Networks

Due to the fact that there is no fixed infrastructure or centralized management in ad hoc wireless networks, a Connected Dominating Set (CDS) of the graph representing the network is widely used as the virtual backbone of the network. Constructing a minimum CDS is NP-hard. In this paper, we propose a completely localized distributed algorithm which is r-CDS to construct a CDS with constant performance ratio. Our algorithm is better at maintenance since there is no need to build a tree or select a leader which are the common methods used in most of the distributed but serialized algorithms. We also compare our algorithm with other localized algorithms. The theoretical and simulation results show that our algorithm has a better performance ratio and constructs a CDS with smaller size in most cases.
The ‘ultimate attribution error’? A review of the literature on intergroup causal attribution

Studies that examine causal attributions for acts by ingroup and outgroup members are reviewed. The tendency for attributions to favour ingroup over outgroup members is found in three paradigms — explanations for positive and negative outcomes, success and failure, and group differences — and in most of the 19 studies reviewed, but the evidence provides only limited support for Pettigrew's (1979) ‘ultimate attribution error’. The evidence is limited to specific dimensions in a given study, but strongest for three general findings: (1) More internal attribution for positive acts, and less internal attribution for negative acts, by ingroup than outgroup members; (2) More attribution of outgroup than ingroup failure to lack of ability, and ‘explaining away’ outgroup success to good luck, high effort or an easy task; (3) A preference for ingroup-serving versus outgroup-serving attributions for group differences. Finally, theoretical issues and methodological shortcomings are discussed with reference to future research.
Risk, threat, and information seeking about genital herpes: The effects of mood and message framing

This paper examines the effect that mood and message frame has on perceived threat, efficacy, attitude, intention and, ultimately, behavior regarding genital herpes information seeking. A 2 (message frame: negative/positive) X 2 (mood: happy/sad) independent groups experiment examining the interaction between mood and message framing was conducted. A two‐way interaction between mood and message framing on the dependent variable(s) was hypothesized such that persons in a sad mood will be more persuaded (as evidenced by heightened threat, efficacy, attitude, intention and behavior) by a negatively framed message given its mood congruent qualities. And, persons in a happy mood were posited to be more persuaded by a positively framed message given its mood congruent qualities. A main effect for mood was also proposed, given that sad persons are expected to pay closer attention to the message(s) overall. These data were partially consistent with the hypotheses. In the main, frame and mood elicited separate effects. Sadness is positively correlated with severity and susceptibility of genital herpes. Frame increases response efficacy. A path model articulating the relationships among all variables is proposed.
'My Madam is Fine': The Adaptation of English Loans in Chichewa

It is well known among sociolinguists that in any language contact situation one language tends to have sociopolitical dominance over the other, and that linguistic borrowing tends to flow from the more dominant to the less dominant language. This paper presents evidence from English loans in Chichewa (Bantu) which shows that the recipient language is not a passive participant in the borrowing process: the borrowing language makes various modifications to the loan words to make them fit the grammatical structure as well as cultural requirements of the recipient language. As a result of these modifications some loan words assume new grammatical categories, meanings and usage.
Minimum connected dominating set construction in wireless networks under the beeping model

Discrete beeping is an extremely rigorous local broadcast model depending only on carrier sensing. It describes an anonymous broadcast network where the nodes do not need unique identifiers and have no knowledge about the topology and size of the network. Within such a model, time is divided into slots, and nodes can either beep or keep silent at each slot. We consider the problem of constructing a minimum dominating set (MDS) and a minimum connected dominating set (MCDS), respectively, under the discrete beeping model in this paper. By assuming that an upper bound N of the network size is known, we first propose and analyze a distributed synchronous algorithm termed BMDS for constructing a minimum dominating set (MDS) and then propose a distributed synchronous algorithm BCDS for CDS construction based on a maximal independent set (MIS) algorithm and a weakly CDS (WCDS). To our best knowledge, we are the first to study the MCDS construction under the discrete beeping model. We prove that the time complexity of BMDS is O(log2 N) rounds with constant approximation ratio of at most 2, and BCDS can converge to a CDS within O(log3 N) rounds.
Sexual coercion in gay male and lesbian relationships: Predictors and implications for support services

Numerous studies have documented the prevalence of forced sex in heterosexual couples. Positive effects of this research include increases in awareness about the problem among helping professionals and the public, as well as increases in support services and prevention programs. However, no research has been done on sexual coercion in gay male and lesbian relationships, and few support services exist. Therefore, this study is an investigation of the prevalence and correlates of coercive sex in gay male and lesbian relationships. Participants were 36 women and 34 men who were in gay or lesbian relationships. The results indicated that 12% of the gay men and 31% of the lesbians reported being victims of forced sex by their current or most recent partners. The higher reporting rate among women may be due to greater awareness of issues pertaining to sexual abuse, and greater likelihood of identifying various forms of coercion as force. For men, being a victim of forced sex was generally associated with being .
Splitting methods for unbounded operators

This paper considers computational methods that split a vector field into three components in the case when both the vector field and the split components might be unbounded. We first employ classical Taylor expansion which, after some algebra, results in an expression for a second-order splitting which, strictly speaking, makes sense only for bounded operators. Next, using an alternative approach, we derive an error expression and an error bound in the same setting which are however valid in the presence of unbounded operators. While the paper itself is concerned with second-order splittings using three components, the method of proof in the presence of unboundedness remains valid (although significantly more complicated) in a more general scenario, which will be the subject of a forthcoming paper.
SAR Processing Based On The Exact Two-dimensional Transfer Function

The two-dimensional transfer functions of several synthetic aperture radar (SAR) focusing algorithms are derived considering the spaceborne SAR environments. The formulation includes the factors of the earth rotation and the antenna squint angles. The resultant transfer functions are explicitly expressed in terms of Doppler centroid frequency and Doppler frequency rate, which can be accurately estimated from the SAR data. Point target simulation results show that the algorithm based on the two-dimensional Fourier transformation outperforms the one-dimensional one for processing data acquired from high squint angles. The two-dimensional Fourier transformation approach appears to be a viable and simple solution for the processor design of future spaceborne SAR systems.
Reliability and validity of the Junior Temperament and Character Inventory

The Junior Temperament and Character Inventory (JTCI) was developed to assess the temperament (‘novelty seeking’, ‘harm avoidance’, ‘reward dependence’, ‘persistence’) and character (‘self‐directedness’, ‘cooperativeness’, ‘self‐transcendence’) dimensions of Cloninger's biosocial model of personality in children and adolescents. The psychometric properties of the JTCI are presented.
A Review of Rician Noise Reduction in MRI Images using Wave Atom Transform

Magnetic resonance imaging is a medical imaging technique that measures the response of atomic nuclei of body tissues to high frequency radio waves when placed in a strong magnetic field and that produces images of the internal organs. De-noising is always a challenging problem in magnetic resonance imaging and important for clinical diagnosis and computerized analysis, such as tissue classification and segmentation. It is well known that the noise in magnetic resonance imaging has a Rician distribution. In this paper, an improved de-noising technique is proposed on Magnetic Resonance Images highly corrupted with Rician Noise using wave atom shrinkage. General Terms Clinical diagnosis, tissue classification, segmentation
Rayleigh scattering, mode coupling, and optical loss in silicon microdisks

High refractive index contrast optical microdisk resonators fabricated from silicon-on-insulator wafers are studied using an external silica fiber taper waveguide as a wafer-scale optical probe. Measurements performed in the 1500 nm wavelength band show that these silicon microdisks can support whispering-gallery modes with quality factors as high as 5.2×10^5, limited by Rayleigh scattering from fabrication induced surface roughness. Microdisks with radii as small as 2.5 µm are studied, with measured quality factors as high as 4.7×10^5 for an optical mode volume of 5.3 (lambda/n)^3.
Effectiveness of the Virtual Reality System Toyra on Upper Limb Function in People with Tetraplegia: A Pilot Randomized Clinical Trial

The aim of this study was to investigate the effects of a virtual reality program combined with conventional therapy in upper limb function in people with tetraplegia and to provide data about patients' satisfaction with the virtual reality system. Thirty-one people with subacute complete cervical tetraplegia participated in the study. Experimental group received 15 sessions with Toyra® virtual reality system for 5 weeks, 30 minutes/day, 3 days/week in addition to conventional therapy, while control group only received conventional therapy. All patients were assessed at baseline, after intervention, and at three-month follow-up with a battery of clinical, functional, and satisfaction scales. Control group showed significant improvements in the manual muscle test (p = 0,043, partial η 2 = 0,22) in the follow-up evaluation. Both groups demonstrated clinical, but nonsignificant, changes to their arm function in 4 of the 5 scales used. All patients showed a high level of satisfaction with the virtual reality system. This study showed that virtual reality added to conventional therapy produces similar results in upper limb function compared to only conventional therapy. Moreover, the gaming aspects incorporated in conventional rehabilitation appear to produce high motivation during execution of the assigned tasks. This trial is registered with EudraCT number 2015-002157-35.
Explorer Pax 6 regulates regional development and neuronal migration in the cerebral cortex

Mutations in the Pax6 gene disrupt telencephalic development, resulting in a thin cortical plate, expansion of proliferative layers, and the absence of the olfactory bulb. The primary defect in the neuronal cell population of the developing cerebral cortex was analysed by using mouse chimeras containing a mixture of wild-type and Pax6-deficient cells. The chimeric analysis shows that Pax6 influences cellular activity throughout corticogenesis. At early stages, Pax6-deficient and wildtype cells segregate into exclusive patches, indicating an inability of different cell genotypes to interact. At later stages, cells are sorted further based on telencephalic domains. Pax6-deficient cells are specifically reduced in the mediocaudal domain of the dorsal telencephalon, indicating a role in regionalization. In addition, Pax6 regulates the process of radial migration of neuronal precursors. Loss of Pax6 particularly affects movement of neuronal precursors at the subventricular zone/intermediate zone boundary at a transitional migratory phase essential for entry into the intermediate zone. We suggest that the primary role of Pax6 is the continual regulation of cell surface properties responsible for both cellular identity and radial migration, defects of which cause regional cell sorting and abnormalities of migration in chimeras. © 2003 Elsevier Science (USA).

Acute gastroenteritis outbreak caused by a GII.6 norovirus.

AIM To report an acute gastroenteritis outbreak caused by a genogroup 2 genotype 6 (GII.6) strain norovirus in Shanghai, China. METHODS Noroviruses are responsible for approximately half of all reported gastroenteritis outbreaks in many countries. Genogroup 2 genotype 4 strains are the most prevalent. Rare outbreaks caused by GII.6 strains have been reported. An acute gastroenteritis outbreak occurred in an elementary school in Shanghai in December of 2013. Field and molecular epidemiologic investigations were conducted. RESULTS The outbreak was limited to one class in an elementary school located in southwest Shanghai. The age of the students ranged from 9 to 10 years. The first case emerged on December 10, 2013, and the last case emerged on December 14, 2013. The cases peaked on December 11, 2013, with 21 new cases. Of 45 students in the class, 32 were affected. The main symptom was gastroenteritis, and 15.6% (5/32) of the cases exhibited a fever. A field epidemiologic investigation showed the pathogen may have been transmitted to the elementary school from employees in a delicatessen via the first case student, who had eaten food from the delicatessen one day before the gastroenteritis episodes began. A molecular epidemiologic investigation identified the cause of the gastroenteritis as norovirus strain GII.6; the viral sequence of the student cases showed 100% homology with that of the shop employees. Genetic relatedness analyses showed that the new viral strain is closely related to previously reported GII.6 sequences, especially to a strain reported in Japan. CONCLUSION This is the first report to show that norovirus strain GII.6 can cause a gastroenteritis outbreak. Thus, the prevalence of GII.6 noroviruses requires attention.
Ultrasound imaging

Ultrasound imaging is now in very widespread clinical use. The most important underpinning technologies include transducers, beam forming, pulse compression, tissue harmonic imaging, contrast agents, techniques for measuring blood flow and tissue motion, and three-dimensional imaging. Specialized and emerging technologies include tissue characterization and image segmentation, microscanning and intravascular scanning, elasticity imaging, reflex transmission imaging, computed tomography, Doppler tomography, photoacoustics and thermoacoustics. Phantoms and quality assurance are necessary to maintain imaging performance. Contemporary ultrasonic imaging procedures seem to be safe but studies of bioeffects are continuing. It is concluded that advances in ultrasonic imaging have primarily been pushed by the application of physics and innovations in engineering, rather than being pulled by the identification of specific clinical objectives in need of scientific solutions. Moreover, the opportunities for innovation to continue into the future are both challenging and exciting.
Gravitational Duals from Equations of State

Holography relates gravitational theories in five dimensions to four-dimensional quantum field theories in flat space. Under this map, the equation of state of the field theory is encoded in the black hole solutions of the gravitational theory. Solving the five-dimensional Einstein's equations to determine the equation of state is an algorithmic, direct problem. Determining the gravitational theory that gives rise to a prescribed equation of state is a much more challenging, inverse problem. We present a novel approach to solve this problem based on physics-informed neural networks. The resulting algorithm is not only data-driven but also informed by the physics of the Einstein's equations. We successfully apply it to theories with crossovers, first- and second-order phase transitions.
ISIS: The Next Generation Router Architecture, Design and Simulation

—High-speed routers have become the new bottleneck in the Internet with the growth of the bandwidth through fiber technology. Switching technology has not grown at the same speed as transmission technology. With the introduction of Dense Wavelength Division Multiplexed networks, the demands on the switch have increased. Also, there is a need for high port density on these routers with a consideration of cost and performance. With all attention being paid to high speed and high port density, we have almost forgotten about the rich variety of services that are to be supported on this network. This constraint requires Quality of Service (QoS) guarantees that make the design much more difficult. In this paper, we look at the design, simulation and evaluation of a high speed router switch ISIS and show that it is possible to make routers with high port density while still meeting the diverse Quality of Service (QoS) requirements that are demanded of routers today.
Helicobacter pylori–Induced IL-1β Secretion in Innate Immune Cells Is Regulated by the NLRP3 Inflammasome and Requires the Cag Pathogenicity Island

Infection with the gram-negative bacterium Helicobacter pylori is the most prevalent chronic bacterial infection, affecting ∼50% of the world’s population, and is the main risk factor of gastric cancer. The proinflammatory cytokine IL-1β plays a crucial role in the development of gastric tumors and polymorphisms in the IL-1 gene cluster leading to increased IL-1β production have been associated with increased risk for gastric cancer. To be active, pro–IL-1β must be cleaved by the inflammasome, an intracellular multiprotein complex implicated in physiological and pathological inflammation. Recently, H. pylori was postulated to activate the inflammasome in murine bone marrow–derived dendritic cells; however, the molecular mechanisms as well as the bacterial virulence factor acting as signal 2 activating the inflammasome remain elusive. In this study, we analyzed the inflammasome complex regulating IL-1β upon H. pylori infection as well as the molecular mechanisms involved. Our results indicate that H. pylori–induced IL-1β secretion is mediated by activation of the nucleotide-binding oligomerization domain-like receptor family, pyrin domain–containing 3 inflammasome. We also show that reactive oxygen species, potassium efflux, and lysosomal destabilization are the main cellular mechanisms responsible of nucleotide-binding oligomerization domain family, pyrin domain–containing 3 inflammasome activation upon H. pylori infection, and identify vacuolating cytotoxin A and cag pathogenicity island as the bacterial virulence determinants involved. Moreover, in vivo experiments indicate an important role for the inflammasome in the onset and establishment of H. pylori infection and in the subsequent inflammatory response of the host.
Relaxed mltiplication using the middle product

In previous work, we have introduced the technique of relaxed power series computations. With this technique, it is possible to solve implicit equations almost as quickly as doing the operations which occur in the implicit equation. In this paper, we present a new relaxed multiplication algorithm for the resolution of linear equations. The algorithm has the same asymptotic time complexity as our previous algorithms, but we improve the space overhead in the divide and conquer model and the constant factor in the F.F. T. model.
Search for a gene responsible for Floating‐Harbor syndrome on chromosome 12q15q21.1

Floating‐Harbor syndrome (FHS) is characterized by characteristic facial dysmorphism, short stature with delayed bone age, and expressive language delay. To date, the gene(s) responsible for FHS is (are) unknown and the diagnosis is only made on the basis of the clinical phenotype. The majority of cases appeared to be sporadic but rare cases following autosomal dominant inheritance have been reported. We identified a 4.7 Mb de novo 12q15‐q21.1 microdeletion in a patient with FHS and intellectual deficiency. Pangenomic 244K array‐CGH performed in a series of 12 patients with FHS failed to identify overlapping deletions. We hypothesized that FHS is caused by haploinsufficiency of one of the 19 genes or predictions located in the deletion found in our index patient. Since none of them appeared to be good candidate gene by their function, a high‐throughput sequencing approach of the region of interest was used in eight FHS patients. No pathogenic mutation was found in these patients. This approach failed to identify the gene responsible for FHS, and this can be explained by at least four reasons: (i) our index patient could be a phenocopy of FHS; (ii) the disease may be clinically heterogeneous (since the diagnosis relies exclusively on clinical features), (iii) these could be genetic heterogeneity of the disease, (iv) the patient could carry a mutation in a gene located elsewhere. Recent descriptions of patients with 12q15‐q21.1 microdeletions argue in favor of the phenocopy hypothesis. © 2012 Wiley Periodicals, Inc.
EDUCATIONAL LEADERSHIP AND MANAGEMENT: THEORY, POLICY, AND PRACTICE

There is great interest in educational leadership in the early part of the 21st century because of the widespread belief that the quality of leadership makes a significant difference to school and student outcomes. There is also increasing recognition that schools require effective leaders and managers if they are to provide the best possible education for their learners. Schools need trained and committed teachers but they, in turn, need the leadership of highly effective principals and support from other senior and middle managers. While the need for effective leaders is widely acknowledged, there is much less certainty about which leadership behaviors are most likely to produce favourable outcomes. I examine the theoretical underpinnings for the field of educational leadership and management, assess different leadership models, and discuss the evidence of their relative effectiveness in developing successful schools.
