Adaptive Activation Functions for Deep Networks

Artiﬁcial neural networks loosely mimic the complex web of nearly 100 trillion connections in the human brain. Deep neural networks, and speciﬁcally convolutional neural networks, have recently demonstrated breakthrough performances in the pattern recognition community. Studies on the network depth, regularization, ﬁlters, choice of activation function, and training parameters are numerous. With regard to activation functions, the rec-tiﬁed linear unit, is favored over the sigmoid and tanh function because the differentiation of larger signals is maintained. This paper introduces multiple activation functions per single neuron. Libraries have been generated to allow individual neurons within a neural network the ability to select between a multitude of activation functions, where the selection of each function is done on a node by node basis to minimize classiﬁcation error. Each node is able to use more than one activation function if the ﬁnal classiﬁcation error can be reduced. The resulting networks have been trained on several commonly used datasets, which show increases in classiﬁcation performance, and are compared to the recent ﬁndings in neuroscience research.
Cultural Effects on the Diagnosis of Autism Spectrum Disorder Among Latinos

The role of culture in autism spectrum disorders (ASD) has been too often neglected in research. The present study evaluated the implications of cultural factors for ASD screening and diagnosis by examining the parenting perceptions and diagnostic experiences of Latina and White mothers of children with ASD. The children of Latina mothers were diagnosed significantly later and were significantly more likely to be diagnosed with autism than with another ASD. Latina mothers demonstrated significantly less knowledge of developmental milestones and of ASD. Latina mothers were also significantly more likely to report early concerns about temperament. The results of this study suggest that both socioeconomic and culturally based differences likely influence the early perception and diagnosis of ASD.
Exact results for perturbative Chern-Simons theory with complex gauge group.

We develop several methods that allow us to compute all-loop partition functions in perturbative Chern-Simons theory with complex gauge group G_C, sometimes in multiple ways. In the background of a non-abelian irreducible flat connection, perturbative G_C invariants turn out to be interesting topological invariants, which are very different from finite type (Vassiliev) invariants obtained in a theory with compact gauge group G. We explore various aspects of these invariants and present an example where we compute them explicitly to high loop order. We also introduce a notion of “arithmetic TQFT” and conjecture (with supporting numerical evidence) that SL(2,C) Chern-Simons theory is an example of such a theory.
A User Data Location Control Model for Cloud Services

A data location control model for Cloud services is presented that uses an authorization system as its core control element. The model is intended for use by enterprises that collect personal data from end users that can potentially be stored and processed at multiple geographic locations. By adhering to the model's authorization decisions, the enterprise can address end users' concerns about the location of their data by incorporating the their preferences about the location of their personal data into authorization policy. The model also ensures that the end users have visibility into the location of their data and are informed when the location of their data changes. A prototype of the model has been implemented that provides the data owner with an interface that allows their location preferences to be expressed. These preferences are stored internally as XACML policy documents. Thereafter, movements or remote duplications of the data must be authorized by submitting requests to an ISO/IEC 10181-3:1996 compliant Policy Enforcement Point. End users can, at any time, view up-to-date information on the locations where their data is stored via a web interface. Furthermore, XACML obligations are used to ensure that end users are informed whenever the location of their data changes.
An Analysis of the Relationship between Mental Health and Psychological Suzhi:from Perspective of Connotation and Structure

Mental health and psychological suzhi are two frequently used concepts in mental health research and education in China in recent years.The ambiguous relationship between them is caused by the no distinct use,which seriously restricted the related issue's scientific understanding and the mental health research and education's positive development.The present study explores the essential relationship between mental health and psychological suzhi through the connotation and structure analysis.Results showed that mental health is a psychological state,while psychological suzhi is stable psychological quality or psychological characteristics.Both of them have an essentially distinction on connotation and structure,while there is a close but not necessarily corresponding relationship on function.Understanding the relationship between each other is not only the need of scientific research,but also the need of making mental health standard and psychological suzhi standard.
Comprehensive Assessment of the Regulons Controlled by the FixLJ-FixK2-FixK1 Cascade in Bradyrhizobium japonicum

ABSTRACT Symbiotic N2 fixation in Bradyrhizobium japonicum is controlled by a complex transcription factor network. Part of it is a hierarchically arranged cascade in which the two-component regulatory system FixLJ, in response to a moderate decrease in oxygen concentration, activates the fixK 2 gene. The FixK2 protein then activates not only a number of genes essential for microoxic respiration in symbiosis (fixNOQP and fixGHIS) but also further regulatory genes (rpoN 1, nnrR, and fixK 1). The results of transcriptome analyses described here have led to a comprehensive and expanded definition of the FixJ, FixK2, and FixK1 regulons, which, respectively, consist of 26, 204, and 29 genes specifically regulated in microoxically grown cells. Most of these genes are subject to positive control. Particular attention was addressed to the FixK2-dependent genes, which included a bioinformatics search for putative FixK2 binding sites on DNA (FixK2 boxes). Using an in vitro transcription assay with RNA polymerase holoenzyme and purified FixK2 as the activator, we validated as direct targets eight new genes. Interestingly, the adjacent but divergently oriented fixK 1 and cycS genes shared the same FixK2 box for the activation of transcription in both directions. This recognition site may also be a direct target for the FixK1 protein, because activation of the cycS promoter required an intact fixK 1 gene and either microoxic or anoxic, denitrifying conditions. We present evidence that cycS codes for a c-type cytochrome which is important, but not essential, for nitrate respiration. Two other, unexpected results emerged from this study: (i) specifically FixK1 seemed to exert a negative control on genes that are normally activated by the N2 fixation-specific transcription factor NifA, and (ii) a larger number of genes are expressed in a FixK2-dependent manner in endosymbiotic bacteroids than in culture-grown cells, pointing to a possible symbiosis-specific control.
A convex pseudolikelihood framework for high dimensional partial correlation estimation with convergence guarantees

Sparse high dimensional graphical model selection is a topic of much interest in modern day statistics. A popular approach is to apply l1‐penalties to either parametric likelihoods, or regularized regression/pseudolikelihoods, with the latter having the distinct advantage that they do not explicitly assume Gaussianity. As none of the popular methods proposed for solving pseudolikelihood‐based objective functions have provable convergence guarantees, it is not clear whether corresponding estimators exist or are even computable, or if they actually yield correct partial correlation graphs. We propose a new pseudolikelihood‐based graphical model selection method that aims to overcome some of the shortcomings of current methods, but at the same time retain all their respective strengths. In particular, we introduce a novel framework that leads to a convex formulation of the partial covariance regression graph problem, resulting in an objective function comprised of quadratic forms. The objective is then optimized via a co‐ordinatewise approach. The specific functional form of the objective function facilitates rigorous convergence analysis leading to convergence guarantees; an important property that cannot be established by using standard results, when the dimension is larger than the sample size, as is often the case in high dimensional applications. These convergence guarantees ensure that estimators are well defined under very general conditions and are always computable. In addition, the approach yields estimators that have good large sample properties and also respect symmetry. Furthermore, application to simulated and real data, timing comparisons and numerical convergence is demonstrated. We also present a novel unifying framework that places all graphical pseudolikelihood methods as special cases of a more general formulation, leading to important insights.
Pancreas transplantation: advantages of both enteric and bladder drainage combined in a two‐step approach

Abstract: Background: Although there is a tendency to perform enteric drainage of pancreas transplants in simultaneous pancreas–kidney (SPK) transplantation, bladder drainage is still preferable in pancreas transplantation alone (PTA) or after a previous kidney transplantation (PAK). Our hypothesis was that enteric conversion of a bladder drained pancreas is an effective and safe procedure. We studied the complication rate and physiological effects of enteric conversion in patients with primary bladder‐drained SPK transplantation.
Cool shapers: Shaping real-time tasks for improved thermal guarantees

With increasing power densities, managing on-chip temperatures has become an important design challenge. We propose a novel approach to this problem with the use of shapers to dynamically and selectively insert idle times during the execution of hard real-time jobs on a single speed processor. For the class of leaky bucket shapers which have a light-weight implementation, we derive the shaper such that no job misses its real-time deadline and the peak temperature is optimally reduced. The analysis and design of such shapers allows for dynamically variable streams of jobs; for instance, periodic streams with jitter. We extend our results to consider non-zero power and timing overhead in transitioning to the idle mode. With experimental results, we demonstrate that the proposed approach provides a large improvement: on average 8K peak temperature reduction or 40% increase in utilization for a given peak temperature.
Design of General User Interface for Automatic Web Service Composition

Automatic Web service composition (AWSC) was proposed to compose new services. Paik et al. (2007) proposed logical and physical Web service composition and ontologies for this. A useful composer needs a Web interface for general users. So a general user interface is designed and implemented in this thesis. This user interface generates some HTML form based on these ontology and additional HTN ontology.
The time-course of processing of grammatical class and semantic attributes of words: Dissociation by means of ERP

espanolEsta investigacion examina el curso temporal del procesamiento de palabras en funcion de su clase gramatical (verbos vs. nombres) y su significado (accion vs. no accion) mediante potenciales evocados. La morfologia de palabras en espanol permite formar un nombre (ej. bail-e) o un verbo (ej. bail-ar) unicamente cambiando el sufijo unido a la raiz. Este hecho permitio la elaboracion de un conjunto de nombres y verbos, igualados en significado y con una misma raiz, referidos a acciones y no acciones. Los resultados obtenidos ponen de manifiesto que la clase gramatical de las palabras es procesada muy pronto, alrededor de 200 ms tras la presentacion de la palabra, manteniendose sus efectos activados en regiones frontales izquierdas hasta los 800 ms. Igualmente se encontro un componente LAN sensible a esta distincion nombres-verbos, y una onda similar al N400, ampliamente distribuida, sensible al procesamiento del significado (accion-no accion). Estos diferentes componentes afectados por la gramatica (P200 y LAN) y el significado (N400) parecen indicar la existencia de un procesamiento neuronal independiente de ambas propiedades linguisticas y apoyan una especificacion lexica de la clase gramatical. EnglishThis study explores the time-course of word processing by grammatical class (verbs vs. nouns) and meaning (action vs. non-action) by means of an ERP experiment. The morphology of Spanish words allows for a noun (e.g., bail-e [a dance]) or a verb (e.g., bail-ar [to dance]) to be formed by simply changing the suffix attached to the root. This facility results in a set of nouns and verbs that are nearly matched in meaning, because of their shared root. The results show that grammatical class of words is processed very early, around 200 ms after the word onset, with the effects remaining activated at left frontal regions until 800 ms. Later components show a focal LAN sensitive to the noun-verb distinction, and a broadly distributed N400-like waveform sensitive to meaning. The different components affected by grammar (P200 and LAN) and meaning (N400) and their topographical dissimilarity seem to indicate an independent neural processing of these two linguistic properties and support a lexical specification of grammatical class.
Investigating the Effects of Fluid Shear Forces on Cellular Responses to Profiled Surfaces in-Vitro: A Computational and Experimental Investigation

The flow conditions in a parallel plate "bioreactor" have been modeled using computational fluid dynamics (CFD) and characterized experimentally using a computer controlled flow regulation apparatus and associated flow visualization techniques. The conditions required to induce flow characteristics appropriate for standard in-vitro cell processes on flat substrates have been identified from a consideration of data from previous studies. The effects of changing the surface topography of the substrate on which the cells are grown has been investigated by forming specific micrometer scale features via hot embossing on polymeric plates. The effect that various features have on the flow that occurs at the boundary layer adjacent to the surface in the parallel plate chamber has been determined. The results for studies undertaken in a parallel plate chamber operating under computer control are presented here. Flow characteristics have been determined using feedback from the sensors within the system and validated by direct flow visualization using fluorescent beads and modeled using a CFD routine. The system exhibits well developed laminar flow and is capable of delivering surface shear stresses up to 2.4 Pa on a planar surface. As such, it is suitable for evaluating in-vitro cell processes. The effects that the features produced by hot embossing of a poly methyl methacrylate (PMMA) surface have been tested in the flow chamber and their influence on shear stress observed.
The role of the Bologna Process in defining Europe

The question of what Europe is remains under-explored in the literature on European matters, and this suggests a need to formulate a definition of ‘Europe’. This paper suggests that it is not possible to resolve the problem of the meaning of Europe without considering its higher education developments. The Bologna Process is a recent European intergovernmental higher education project having the aim of forming the European Higher Education Area by making degrees compatible in its signatory countries. In addition, other countries beyond this Area also intend to adopt the Bologna Process in order to converge their higher education structures. It is argued that the Bologna Process is an essential consideration in approaching the definition of Europe because it expands European borders and promotes the idea of a common European identity within them. These changes are supplemented by building up tensions in the development of territory–identity compatibility in the growing European community. The difficulty, if not impossibility, of solving these problems makes Europe dynamic in the Bologna Process, and suggests the depth of the meaning the borders, delineated by the Bologna Process, convey.
Regulation of chymase production in human mast cell progenitors.

BACKGROUND Although mature tryptase-positive mast cells (MCs) and tryptase and chymase double-positive MCs are recognized using in situ staining and are preferentially distributed in different tissues, recent findings suggest that tryptase-positive MCs can give rise to tryptase and chymase double-positive MCs. OBJECTIVE We investigated the regulation of chymase production in developing MCs. METHODS Human cord blood or peripheral blood cells were cultured in the presence of stem cell factor and IL-6 with or without IL-4 in methylcellulose or liquid medium. Intracellular chymase and tryptase were determined with immunocytochemistry, flow cytometry, and ELISA. Chymase messenger RNA expression was examined with 3 different methods, such as Northern blotting. RESULTS Flow cytometric analysis always showed a unimodal histogram of chymase-positive, as well as tryptase-positive, cells in the presence of various cytokines, even when chymase was not detected in some MCs with immunocytochemistry. The chymase protein expression increased by culture duration and was enhanced by cytokines, such as a high concentration of stem cell factor or IL-4. Chymase messenger RNA was expressed higher in immature MCs than mature chymase protein-rich MCs. We generated macroscopic MC colonies in methylcellulose by culturing CD34(+) cells for 10 weeks and measured cellular chymase, tryptase, and histamine. The chymase/histamine ratio widely varied (0.07-1.01) depending on MC colony, even under the same culture conditions, including IL-4, whereas the tryptase/histamine ratio was relatively constant (1.02-1.89). CONCLUSION All human MCs in culture are capable of producing chymase, and the production is clonally regulated at their progenitors by cytokine-independent mechanisms, as well as being totally controlled by cytokine-dependent mechanisms accompanied by maturation.
Association between Serum Magnesium Levels and Depression in Stroke Patients

Post-stroke depression (PSD) is a common psychiatric complication of stroke that is associated with a poor outcome in stroke patients. Our aim was to assess the association between the serum magnesium levels and the presence of PSD in Chinese patients. Two hundred nine stroke patients were included in the study. Depressive symptoms were measured by the 17-Hamilton Rating Scale for Depression at 3 months after stroke. Based on the depressive symptoms, diagnoses of depression were made in line with the DSM-IV criteria for PSD. Serum magnesium levels were evaluated using the dimethyl aniline blue colorimetric method at admission. Multivariate analyses were conducted using logistic regression models. Further, 120 normal subjects were recruited, and their serum magnesium levels were also measured as control. At 3 months, fifty-nine patients (28.2%) were diagnosed as PSD. The serum magnesium levels were significantly lower in both PSD patients and non-PSD patients than in normal subjects (p < 0.001). Indeed, patients with PSD showed lower serum magnesium levels (p < 0.001) than did non-PSD patients at admission. In the multivariate analyses, after adjusting for potential variables, we found that an increased risk of PSD was associated with serum magnesium levels ≤ 0.84mmol/L (OR 2.614, 95% CI 1.178-5.798, p=0.018). Low serum magnesium levels at admission were found to be associated with the presence of PSD at 3 months after stroke.
Spezifische Selbstwirksamkeit zur Beeinflussung des sexuellen Interesses an Kindern (SSIK): Konstruktion und Validierung eines Messinstruments

Zusammenfassung Anliegen der vorliegenden Studie war die Konstruktion und Validierung eines Instruments zur Erfassung der spezifischen Selbstwirksamkeit zur Beeinflussung des sexuellen Interesses an Kindern (SSIK). Der Konstruktionsprozess beinhaltete 2 Expertenreviews und führte zu einem Selbstberichtsfragebogen mit 6 Items (SSIK-Skala). Für die Validierung wurde die Skala zusammen mit einer Reihe weiterer psychometrischer Instrumente einer Stichprobe bestehend aus 56 Männern mit einem sexuellen Interesse an Kindern vorgelegt. Die Ergebnisse zeigten eine gute interne Konsistenz (Reliabilität) der SSIK-Skala mit Cronbach’s α=0,87. Die gute Konstruktvalidität zeigt sich vor allem in der erwarteten positiven Beziehung der Skala zu anderen Aspekten der Sexualität wie der sexuellen Selbstwirksamkeit (r=0,54, p<0,01) und in der negativen Beziehung zur externalen Kontrollüberzeugung (r=−0,25, p<0,10). Die Korrelationen zu weiteren Variablen wie der allgemeinen Selbstwirksamkeit (r=0,15, p=0,29) oder Depressivität (r=−0,18, p=0,19) weisen zwar die erwartete Richtung des Zusammenhangs auf, zeigen aber keine statistische Signifikanz. Die Ergebnisse geben Hinweis auf die Existenz eines Konstruktes, das als SSIK bezeichnet werden kann und implizieren weitergehende Studien, die die Beeinflussbarkeit der SSIK durch Interventionen untersuchen.
Dirty Dozen and Short Dark Triad: a Chinese Validation of Two Brief Measures of the Dark Triad

Objective: To assess the reliability and validity of the Chinese version of Dirty Dozen(DD) and Short Dark Triad(SD3) in Chinese population. Methods: The Chinese version of Dirty Dozen(DD) and Short Dark Triad(SD3) were administered to a sample of university students(n=577). The test-retest reliability was assessed in 54 university students who were re-administered the questionnaire 6 weeks after the first administration. Results: 1In this sample, the Chinese version of DD fit the data well(χ2/df=3.086, RMSEA=0.077, NFI=0.930, CFI=0.951, GFI=0.928), and the loadings of all items were higher than 0.50. 2 The Chinese version of SD3 fit not well(χ2/df=2.893, RMSEA=0.073, NFI=0.661, CFI=0.746,GFI=0.809). 3Cronbach's alpha of DD and its three subscales were 0.757-0.902, the test-retest reliability 6 weeks after were 0.725-0.879. Based on original scale, Cronbach's alpha of SD3 and its three subscales were 0.484-0.830, the test-retest reliability were 0.330- 0.784. 4 Machiavellianism and Psychopathy were positively correlated with neuroticism(P0.01), and negatively correlated with conscientiousness, agreebleness, openness and extraversion(P0.05-0.01). Narcissism was positively correlated with neuroticism, conscientiousness, agreebleness, openness and extraversion(P0.01). DD and SD3 were positively correlated with the total score of aggressive behavior and its five subscales(P0.01). 5There was a main effect of sex on DD and SD3, with males scoring higher on Machiavellianism, Narcissism(SD3 only) and Psychopathy(P0.01). Conclusion: The Chinese version of DD shows good psychometric features except Narcissism. SD3 seems not to function well in Chinese university students, future research will be needed to find items that represent in Chinese settings.
