Novelty Detection in MultiClass Scenarios with Incomplete Set of Class Labels

We address the problem of novelty detection in multiclass scenarios where some class labels are missing from the training set. Our method is based on the initial assignment of confidence values, which measure the affinity between a new test point and each known class. We first compare the values of the two top elements in this vector of confidence values. In the heart of our method lies the training of an ensemble of classifiers, each trained to discriminate known from novel classes based on some partition of the training data into presumed-known and presumednovel classes. Our final novelty score is derived from the output of this ensemble of classifiers. We evaluated our method on two datasets of images containing a relatively large number of classes - the Caltech-256 and Cifar-100 datasets. We compared our method to 3 alternative methods which represent commonly used approaches, including the one-class SVM, novelty based on k-NN, novelty based on maximal confidence, and the recent KNFST method. The results show a very clear and marked advantage for our method over all alternative methods, in an experimental setup where class labels are missing during training.
The impact of information systems on organizations and markets

The adoption of information technology (IT) in organizations has been growing at a rapid pace. The use of the technology has evolved from the automation of structured processes to systems that are truly revolutionary in that they introduce change into fundamental business procedures. Indeed, it is believed that “More than being helped by computers, companies will live by them, shaping strategy and structure to fit new information technology [25]. ” While the importance of the relationship between information technology and organizational change is evidenced by the considerable literature on the subject,1 there is a lack of comprehensive analysis of these issues from the economic perspective. The aim of this article is to develop an economic understanding of how information systems affect some key measures of organization structure.
Climatic Associations of British Species Distributions Show Good Transferability in Time but Low Predictive Accuracy for Range Change

Conservation planners often wish to predict how species distributions will change in response to environmental changes. Species distribution models (SDMs) are the primary tool for making such predictions. Many methods are widely used; however, they all make simplifying assumptions, and predictions can therefore be subject to high uncertainty. With global change well underway, field records of observed range shifts are increasingly being used for testing SDM transferability. We used an unprecedented distribution dataset documenting recent range changes of British vascular plants, birds, and butterflies to test whether correlative SDMs based on climate change provide useful approximations of potential distribution shifts. We modelled past species distributions from climate using nine single techniques and a consensus approach, and projected the geographical extent of these models to a more recent time period based on climate change; we then compared model predictions with recent observed distributions in order to estimate the temporal transferability and prediction accuracy of our models. We also evaluated the relative effect of methodological and taxonomic variation on the performance of SDMs. Models showed good transferability in time when assessed using widespread metrics of accuracy. However, models had low accuracy to predict where occupancy status changed between time periods, especially for declining species. Model performance varied greatly among species within major taxa, but there was also considerable variation among modelling frameworks. Past climatic associations of British species distributions retain a high explanatory power when transferred to recent time – due to their accuracy to predict large areas retained by species – but fail to capture relevant predictors of change. We strongly emphasize the need for caution when using SDMs to predict shifts in species distributions: high explanatory power on temporally-independent records – as assessed using widespread metrics – need not indicate a model’s ability to predict the future.
The Relations among Religiosity, Subjective Well-being, and Attitudes towards Science

Abstract Research in three last decades has linked religiosity with health and Subjective Well-Being (SWB), suggesting that religion leads to physical and mental health. Recently, it has been shown that science can often do the same. This study aims to investigate the relationship of religiosity and attitudes towards science to SWB. Two hundred and eighteen university students and 122 seminary school students were selected through non-random, convenience sampling and filled out the following scales: Scientific Attitude Assessment scale (SAAS), Spirituality Self-Rating Scale (SSRS), Satisfaction with Life Scale (SWLS), and Subjective Happiness Scale (SHS). Results showed that religiosity was positively correlated with happiness and life satisfaction. Religious people reported more positive attitudes towards science, showing that at the personal level they do not see much of a conflict between their religion and contemporary science. Life satisfaction and happiness were also positively associated with positive attitudes towards science. While seminary school students reported higher levels of religiosity, university students reported higher scores on extrinsic attitudes towards science but not intrinsic attitudes. These results demonstrated the positive links between religiosity and attitudes towards science, suggesting that both religion and science can contribute to SWB.
A constraint shifting homotopy method for computing fixed points on nonconvex sets

In this paper, a constraint shifting homotopy method for solving fixed point problems on nonconvex sets is proposed and the existence and global convergence of the smooth homotopy pathways is proved under some mild conditions. Compared with the previous results, the newly proposed homotopy method requires that the initial point needs to be only in the shifted feasible set not necessarily in the original feasible set, which relaxes the condition that the initial point must be an interior feasible point. Some numerical examples are also given to show the feasibility and effectiveness of our method. c ©2016 All rights reserved.
Computing Stereo Disparity and Motion with Known Binocular Cell Properties

Many models for stereo disparity computation have been proposed, but few can be said to be truly biological. There is also a rich literature devoted to physiological studies of stereopsis. Cells sensitive to binocular disparity have been found in the visual cortex, but it is not clear whether these cells could be used to compute disparity maps from stereograms. Here we propose a model for biological stereo vision based on known receptive field profiles of binocular cells in the visual cortex and provide the first demonstration that these cells could effectively solve random dot stereograms. Our model also allows a natural integration of stereo vision and motion detection. This may help explain the existence of units tuned to both disparity and motion in the visual cortex.
Renal Vein Thrombosis in a Newborn With Abnormal Factor VIII Level

Abstract Renal vein thrombosis (RVT) in neonates is a rare condition of low mortality but significant morbidity due to renal impairment. We report the case of a male term newborn with left RVT and elevated serum factor VIII (FVIII). The main symptoms of the patient and the important clinical findings: prompt diagnosis of RVT was possible because the classic clinical presentation of macroscopic hematuria, thrombocytopenia, and palpable flank mass were present in this newborn infant. The main diagnoses: finally, the reason of RVT was established when the infant was 3 months of age: the increased level of FVIII was confirmed. We discuss the diagnosis, therapy, and outcome of the patient and compare with the literature. Therapeutics interventions: however, despite anticoagulant therapy the left kidney developed areas of scarring and then atrophy. Conclusions and outcomes: Prothrombotic defects should be considered in all patients with perinatal RVT. Elevated factor VIII as a reason of RVT in neonatal period is particularly rare. Given a poor renal outcome in children associated with elevated levels of factor VIII, consideration could be given to more aggressive antithrombotic therapy in such cases.
OpenNMT: Open-Source Toolkit for Neural Machine Translation

We describe an open-source toolkit for neural machine translation (NMT). The toolkit prioritizes efficiency, modularity, and extensibility with the goal of supporting NMT research into model architectures, feature representations, and source modalities, while maintaining competitive performance and reasonable training requirements. The toolkit consists of modeling and translation support, as well as detailed pedagogical documentation about the underlying techniques.
State feedback switched control of discrete-time switched linear systems with application to networked control

This paper treats the state feedback switched control design problem for discrete-time switched linear systems. More specifically, the control goal is to design a set of state feedback gains together with a state dependent switching function assuring stability and H2, H∞ performance indexes. The conditions are based on Lyapunov or Riccati-Metzler inequalities which although are difficult to solve for a large number of subsystems, allow the derivation of simpler alternative conditions expressed by LMIs whenever a scalar variable is fixed. This theory is well adapted to treat an important networked control problem known as discrete-time self-triggered control design problem, where the switching rule is responsible for the scheduling of the sampling periods to be considered in the communication channel at each sampling time instant in order to improve performance. This method is compared theoretically with others from literature. Academical examples are used for comparisons and to show the validity of the proposed technique in both contexts, switched and networked control systems.
Melt channelization in ascending mantle

[1] We study a model for channels of magma flow within mantle undergoing decompression melting. Cylindrical conduits in a viscous, porous, compacting matrix are considered, and it is found that the dynamics of the conduit walls are governed by the competition between melting (caused by decompression) and viscous closure (caused by the reduced pressure in the conduit). There are many similarities with the Rothlisberger channels which transport melt water beneath glaciers. Pressure in these mantle conduits is very nearly magmastatic, and ascent velocities on the order of 100 m a−1 are predicted. Flow from the surrounding porous partially molten matrix into the low-pressure channel is considered and can supply a continual source of melt. The accumulation region is on the order of the compaction length, and the residual matrix is reduced to very low melt fractions, typically <0.5%. Channels form naturally from porous flow in the matrix because of the enhanced melting rate in regions of higher porosity, which have a larger heat flux from below. The vast majority of melt could be expected to flow eventually into one of these channels, which therefore offer a physical grounding for the conceptual near-fractional melting models used to explain field observations.
Density of familial alcoholism and its effects on alcohol use and problems in college students.

BACKGROUND Previous studies of family history of alcoholism (FHA) in college students have typically relied on dichotomous indices of paternal drinking. This study examined the prevalence of FHA and its effects on alcohol use and problems using a density measure in a sample (n = 408) of college students. METHODS Undergraduate students completed an anonymous survey in exchange for course credit. Data was collected between 2005 and 2006. RESULTS Using a density measure of FHA, we observed an overall prevalence rate of 65.9% and a rate of 29.1% for FHA in both first and second-degree relatives. Structural equation modeling (SEM) was used to investigate relations among FHA, alcohol use/problems and previously identified etiological risk factors for alcohol use disorders (AUD). Results indicated a significant positive association between FHA and alcohol-related problems and this relationship was mediated by age of onset of drinking, behavioral undercontrol and current cigarette use. Behavioral undercontrol also mediated the relationship between gender and alcohol problems. Additionally, FHA was associated with an earlier age of onset of drinking and this was related to greater alcohol use. CONCLUSIONS Assessing density of FHA in future trajectory research may capture a greater number of students at risk for acute alcohol-related problems and/or future development of AUDs. Future preventive interventions with this population, which should begin well before the college years, may benefit from considering personality factors and incorporating smoking cessation to help identify at-risk students and assist those who wish to cut down on their alcohol use but find that smoking acts as a trigger for increased drinking.
Matrix Factorisation for Scalable Energy Breakdown

Homes constitute more than one-thirds of the total energy consumption. Producing an energy breakdown for a home has been shown to reduce household energy consumption by up to 15%, among other benefits. However, existing approaches to produce an energy breakdown require hardware to be installed in each home and are thus prohibitively expensive. In this paper, we propose a novel application of feature-based matrix factorisation that does not require any additional hard- ware installation. The basic premise of our approach is that common design and construction patterns for homes create a repeating structure in their energy data. Thus, a sparse basis can be used to represent energy data from a broad range of homes. We evaluate our approach on 516 homes from a publicly available data set and find it to be more effective than five baseline approaches that either require sensing in each home, or a very rigorous survey across a large number of homes coupled with complex modelling. We also present a deployment of our system as a live web application that can potentially provide energy breakdown to millions of homes.
Rapid Intensification of a Sheared, Fast-Moving Hurricane over the Gulf Stream

AbstractHurricane Irene (1999) rapidly intensified from 65 to 95 kt (~33.4 to 48.9 m s−1) in 18 h. During the rapid intensification (RI) period, the northeastward storm motion increased from 10 to 18 m s−1, the ambient southwesterly vertical wind shear increased from 6–7 to 10–13 m s −1, and the downshear tilt of the inner core vortex increased. The azimuthal wavenumber-1 asymmetric convection that developed was consistent with a superposition of shear-induced and storm motion–induced forcing for vertical motion downshear and ahead of the center. Although the diabatic heating remained strongly asymmetric, it was of sufficient intensity to dramatically increase the azimuthally averaged heating. This heating occurred almost entirely inside the radius of maximum winds, a region known to favor rapid warm core development and spinup of the vortex. It is hypothesized that asymmetric forcing from the large vertical wind shear and rapid storm motion were responsible for RI. An unanswered question is what determin.
Caste-Specific Expression Patterns of Immune Response and Chemosensory Related Genes in the Leaf-Cutting Ant, Atta vollenweideri

Leaf-cutting ants are evolutionary derived social insects with elaborated division of labor and tremendous colony sizes with millions of workers. Their social organization is mainly based on olfactory communication using different pheromones and is promoted by a pronounced size-polymorphism of workers that perform different tasks within the colony. The size polymorphism and associated behaviors are correlated to distinct antennal lobe (AL) phenotypes. Two worker phenotypes differ in number of olfactory glomeruli in the AL and the presence or absence of an extremely large glomerulus (macroglomerulus), involved in trail-pheromone reception. The males' AL contains three macroglomeruli which are presumably involved in detection of sex-pheromone components. We investigated the antennal transcriptome data of all major castes (males, queens and workers) and two worker subcastes (large and tiny workers). In order to identify putative odorant receptor genes involved in pheromone detection, we identified differentially expressed odorant receptor genes (OR-genes) using custom microarrays. In total, we found 185 OR-gene fragments that are clearly related to ORs and we identified orthologs for 70 OR-genes. Among them one OR-gene differs in relative expression between the two worker subcastes by a factor of >3 and thus is a very promising candidate gene for the trail-pheromone receptor. Using the relative expression of OR-genes in males versus queens, we identified 2 candidates for sex-pheromone receptor genes in males. In addition, we identified genes from all other chemosensory related gene families (13 chemosensory protein genes, 8 odorant binding protein genes, 2 sensory-neuron membrane protein genes, 7 ionotropic receptor genes, 2 gustatory receptor genes), and we found ant-specific expansions in the chemosensory protein gene family. In addition, a large number of genes involved in immune defense exhibited differential expression across the three different castes, and some genes even between the two worker subcastes.
Defining the Family Business by Behavior

It is generally accepted that a family's involvement in the business makes the family business unique; but the literature continues to have difficulty defining the family business. We argue for a distinction between theoretical and operational definitions. A theoretical definition must identify the esence that distinguishes the family business from other businesses. It is the standard against which operational definitions must be measured. We propose a theoretical definition based on behavior as the essence of a family business. Our conceptual analysis shows that most of the operational definitions based on the components of family involvement overlap with our theoretical definition. Our empirical results suggest, however, that the components of family involvement typically used in operational definitions are weak predictors of intentions and, therefore, are not always reliable for distinguishing family businesses from non-family ones.
Defining Gender-Responsive Services in a Juvenile Court Setting

Scholars have documented the importance of developing gender-responsive services for girls in order to address their unique needs and reasons for entering the juvenile justice system. Although researchers have made progress in efforts to develop gender-responsive services, the research and policy literature does not provide a clear definition of what constitutes a gender-responsive approach. This study examined qualitative interviews with juvenile court staff (N = 39). Court staff lacked familiarity with gender-responsivity and most used the term interchangeably with gender-specificity. However, multiple court staff expressed a need for programming for girls and more research on the effectiveness of gender-responsive services.
Teaching a Child with Autism to Respond to the Question, “What Else?”

In this study, a child with autism was taught to respond to the question, “What else? ” The purpose of this study was to examine an effective procedure to acquire appropriate responses when asked for additional information. The participant was first asked what he associated with an animal before being asked for additional information. To teach correct responses, a prompt fading procedure was used. The results revealed the procedure was effective. Furthermore, the behavioral variability of the participant increased at the completion of the procedure. The results revealed that children with autism can acquire appropriate responses, and the acquisition of these responses affects the degree of behavioral variability.
Heat stress acutely activates insulin-independent glucose transport and 5′-AMP-activated protein kinase prior to an increase in HSP72 protein in rat skeletal muscle

Heat stress (HS) stimulates heat shock protein (HSP) 72 mRNA expression, and the period after an increase in HSP72 protein is characterized by enhanced glucose metabolism in skeletal muscle. We have hypothesized that, prior to an increase in the level of HSP72 protein, HS activates glucose metabolism by acutely stimulating 5′‐AMP‐activated protein kinase (AMPK). Rat epitrochlearis muscle was isolated and incubated either with or without HS (42°C) for 10 and 30 min. HS for 30 min led to an increase in the level of Hspa1a and Hspa1b mRNA but did not change the amount of HSP72 protein. However, HS for both 10 and 30 min led to a significant increase in the rate of 3‐O‐methyl‐d‐glucose (3MG) transport, and the stimulatory effect of 3MG transport was completely blocked by cytochalasin B. HS‐stimulated 3MG transport was also inhibited by dorsomorphin but not by wortmannin. HS led to a decrease in the concentration of ATP, phosphocreatine, and glycogen, to an increase in the level of phosphorylation of AMPKα Thr172, and to an increase in the activity of both AMPKα1 and AMPKα2. HS did not affect the phosphorylation status of insulin receptor signaling or Ca2+/calmodulin‐dependent protein kinase II. These results suggest that HS acts as a rapid stimulator of insulin‐independent glucose transport, at least in part by stimulating AMPK via decreased energy status. Although further research is warranted, heat treatment of skeletal muscle might be a promising method to promote glucose metabolism acutely.
Grafting Helps Improve Photosynthesis and Carbohydrate Metabolism in Leaves of Muskmelon

The most important quality for muskmelon (Cucumis melo L.) is their sweetness which is closely related to the soluble sugars content. Leaves are the main photosynthetic organs in plants and thus the source of sugar accumulation in fruits since sugars are translocated from leaves to fruits. The effects of grafting muskmelon on two different inter-specific (Cucurbita maxima×C. moschata) rootstocks was investigated with respect to photosynthesis and carbohydrate metabolism. Grafting Zhongmi1 muskmelon on RibenStrong (GR) or Shengzhen1 (GS) rootstocks increased chlorophyll a, chlorophyll b and chlorophyll a+b content and the leaf area in middle and late developmental stages of the plant compared to the ungrafted Zhongmi1 check (CK). Grafting enhanced the net photosynthesis rate, the stomatal conductance, concentration of intercellular CO2 and transpiration rate. Grafting influenced carbohydrates contents by changing carbohydrate metabolic enzymes activities which was observed as an increase in acid invertase and neutral invertase activity in the functional leaves during the early and middle developmental stages compared to CK. Grafting improved sucrose phosphate synthase and stachyose synthase activities in middle and late developmental stages, thus translocation of sugars (such as sucrose, raffinose and stachyose) in GR and GS leaves were significantly enhanced. However, compared with CK, translocation of more sugars in grafted plants did not exert feedback inhibition on photosynthesis. Our results indicate that grafting muskmelon on inter-specific rootstocks enhances photosynthesis and translocation of sugars in muskmelon leaves.
