Multi-representation approach to text regression of financial risks

Different approaches for textual feature extraction have been proposed starting with simple word count features and continuing with deeper representations capturing distributional semantics. In recent publications word embedding methods have been successfully used as a representation basis for a large number of NLP tasks like text classification, part of speech tagging and many others. In this article we explore opportunities of using multiple text representations simultaneously within one regression task in order to exploit conventional bag of words approach with the more semantically rich embeddings. We investigate performance of this multi-representation approach on the financial risk prediction problem. Publicly available 10-K reports filled by US trading companies are used as the basis for predicting next year change in stock price volatility. Our study shows that models based on single representations achieve performance that is comparable to the previously published results on risk prediction and models with multiple representations benefit from complementary information and outperform both baseline and single representation models.
Symplectic quaternion scheme for biophysical molecular dynamics

Massively parallel biophysical molecular dynamics simulations, coupled with efficient methods, promise to open biologically significant time scales for study. In order to promote efficient fine-grained parallel algorithms with low communication overhead, the fast degrees of freedom in these complex systems can be divided into sets of rigid bodies. Here, a novel Hamiltonian form of a minimal, nonsingular representation of rigid body rotations, the unit quaternion, is derived, and a corresponding reversible, symplectic integrator is presented. The novel technique performs very well on both model and biophysical problems in accord with a formal theoretical analysis given within, which gives an explicit condition for an integrator to possess a conserved quantity, an explicit expression for the conserved quantity of a symplectic integrator, the latter following and in accord with Calvo and Sanz-Sarna, Numerical Hamiltonian Problems (1994), and extension of the explicit expression to general systems with a flat phase space.
The Importance of Trust in Manager-Employee Relationships

Trust is a complex and multidimensional phenomenon. Organizational trust is an important part of professional relationships between co-workers, between managers and employees, or between employees and managers. Trust can be either interpersonal or institutional in nature. To measure, understand, and explain trust in an organizational context, it is important to identify different dimensions of trust (competence, benevolence, and integrity), different types of trust (horizontal trust between co-workers, vertical trust between managers and employees, and vertical trust between employees and managers), and the roles that different dimensions of trust have in different types of trust. The aim of this paper is to determine the roles that the different dimensions of trust have in each of the different types of trust at Gaia, a Polish lingerie company. Study results show competence is the least important dimension of trust in all of the different types of trust at Gaia, the Polish lingerie company. Integrity is the most important dimension of trust in relationships between co-workers. Benevolence is the most important dimension of trust in relationships between employees and managers.
Summarization System Evaluation Variations Based on N-Gram Graphs

Within this article, we present the application of the AutoSummENG method within the TAC 2010 AESOP challenge. We further present two novel evaluation methods based on n-gram graphs. The first method is called Merged Model Graph (MeMoG) and it uses the ngram graph framework to represent a set of documents with a single, “centroid” graph, offering state-of-the-art performance. The second method is called Hierarchical Proximity Graph (HPG) evaluation and it uses a hierarchy of graphs to represent texts, aiming to represent different granularity levels under a unified view. The experiments indicate that both novel methods offer very promising performance in different aspects of evaluation, improving on AutoSummENG scores.
On Stability, Clarity, and Co-occurrence of Self-Tagging

Most studies on tags focus on collaborative tagging systems where each resource (e.g., article, photo) can be tagged by multiple users with multiple tags. The tag usage patterns in self-tagging systems where a resource (e.g., a blog post) can only be tagged by its owner, however, have not been well studied. From the tags assigned by bloggers to their own blog posts, we obtain interesting insights on tag distribution stability and tag clarity. We further discuss the meaning of tag co-occurrences in the context of blogs and argue that tag networks based on co-occurrence from self-tagging system needs to be interpreted differently than that in collaborative tagging systems.
Image Noise Estimation Using A Variation-Adaptive Evolutionary Approach

The estimation of noise statistics is critical to optimize many computer vision algorithms. The main issue is how to identify the homogeneous image patches for estimating the noise statistics. The smallest variance used in the conventional approaches is not always a good measure of homogeneity of image patches. In addition, the conventional approaches neglect the fact that homogeneous image patches tend to cluster together due to local spatial smoothness in images. In view of this, a new image noise estimation approach is proposed in this letter. The proposed approach has two key components. First, a graphical representation is proposed to model the relationship among image patches. Second, the ant colony optimization (ACO) technique is used to automatically select a set of patches for estimating the noise statistics. To be more specific, the proposed approach guides the spatial movement of artificial ants towards homogeneous locations in the graph, by considering both global (i.e., clustering measure) properties and local (i.e., homogeneity measure) properties of patches. Experimental results are provided to justify that the proposed approach out-performs nine conventional approaches to provide more accurate noise statistics estimation.
Realization of three phase cascaded H-Bridge multi-level inverter as Shunt Active Filter

This paper presents a three-phase cascaded H-Bridge MLI as Shunt Active Filter intended for installation on industrial and utility of power distribution system is widely accepted and implemented as a solution to the power quality problems in utility, industry and commercial applications. This paper proposes the design of a shunt active power filter under the condition of voltage sag, unbalanced loads. The active power filter, which can be used under the condition of voltage sag, unbalanced or distorted source voltages, can be applicable to compensate the harmonics, reactive and negative sequence currents. The main objective of this paper is to regulate the voltage in distribution systems against any power quality issues like voltage sag, unbalancing and to reduce the harmonics using cascaded multilevel inverter as Shunt active filter.
Les propriétés lexicales et syntaxiques de benben en français québécois

Abstract The aim of this paper is to analyze the various lexical and syntactic properties of the reduplicated adverbial form benben in Quebec French. It can be observed that this form differs syntactically from its Standard French synonyms beaucoup and très. Benben can indeed appear with various lexical categories: nouns, adjectives, adverbs, transitive and intransitive verbs. Moreover, in many contexts, its use is sensitive to the presence of verbal negation, rather than to that of constituent negation. In comparison with other Quebec French quantifiers, benben is very flexible. It can be used in both negative and positive contexts and, as an adverbial form, it can appear in various positions in the sentence.
Fast Optimization Based Motion Planning and Path-Tracking Control for Car Parking

Abstract This paper presents a car parking control concept for real-time application. It utilizes a two-degrees-of-freedom control scheme consisting of a feedforward and a feedback controller. The reference trajectory is constructed in two steps. First a geometric path is planned by solving a local static optimization problem, which is formulated by discretizing the path. Second a pathfollowing problem in the form of an optimal control problem considering the physical limitations is solved. The solution of this optimal control problem yields the time parametrization of the geometric path. In order to account for model uncertainties and disturbances, a Lyapunovbased feedback controller is designed for the trajectory error system. Simulation studies show the applicability and efficiency of the proposed approach.
Formal Semantics for the Java Modeling Language

A common critique of formal methods in software development practise is, that they are not readily understandable and thus not widely used (see for instance [Nam97]). The Java Modeling Language (JML) was created in an attempt to bridge that gap. By building upon the syntax of Java it is meant to be easily accessible to the common user – who might not be skilled in formal modeling. Due to this advantage, JML has quickly become one of most popular specification languages to use with both static and runtime analysis of programs. JML specifications are written in a Java-like expression language as comments straight into source files. It provides both in-code assertions as well as method contracts and class invariants which are indicated by appropriate preceding keywords. Fig. 1 shows a method specification. However, the official reference [LPC09] mostly lacks a clear definition of semantics. In turn, several tools implementing JML syntax use their own interpretations. Past approaches to formal semantics have rather been documentations of those tools than providing a unified reference.
Adaptive Market Design with Linear Charging and Adaptive k-Pricing Policy

We describe a possible design strategy for a market specialist in the TAC Market Design Competition. Specifically, we describe both a linear charging policy that steadily increases the fees charged to trading agents interacting with the market, and an adaptive pricing policy that alters the trading price of goods based on the relative numbers of buyers and sellers in the market and the previous history of the market condition. We offer up two different sets of experimental data, the first to illustrate some basic properties about successful markets in the Market Design Competition, and the second to show the relative superiority of our chosen strategies over several possible alternatives.
Perceptually-constrained generalized singular value decomposition-based approach for enhancing speech corrupted by colored noise

In a previous work, we have successfully integrated the transformation-based signal subspace technique with the generalized singular value decomposition (GSVD) algorithm to develop an improved speech enhancement framework [1]. In this paper, we further incorporate the perceptual masking effect of the psychoacoustics model as extra constraints of the previously proposed GSVD-based algorithm to obtain improved sound feature, and furthermore make sure the undesired residual noise to be nearly unperceivable. Both subjective listening tests and spectrogram-plot comparison showed that the closed-form solution developed here can offer significantly better speech quality than either the conventional spectral subtraction algorithm or the previously proposed GSVD-based technique, regardless of whether the additive noise is white or not.

Deciding Entailment and Contradiction with Stochastic and Edit Distance-based Alignment

Analysis stage. Our goal at this stage is to compute linguistic representations of the passage and the hypothesis that contain as much information as possible about their semantic content. We use typed dependency graphs generated by the Stanford parser (Klein and Manning, 2003; de Marneffe et al., 2006), which contain a node for each word and labeled edges representing the grammatical relations between words. Named entities are identified by a CRF-based NER system, and contiguous collocations which appear in WordNet are collapsed.
Mice expressing a mutant desmosomal cadherin exhibit abnormalities in desmosomes, proliferation, and epidermal differentiation

Desmogleins are members of the cadherin superfamily which form the core of desmosomes. In vitro studies indicate that the cytoplasmic domain of desmogleins associates with plakoglobin; however, little is known about the role of this domain in desmosome recognition or assembly in vivo, or about the possible relation of desmoglein mutations to epidermal differentiation and disease. To address these questions we used transgenic mouse technology to produce an NH2-terminally truncated desmoglein (Pemphigus Vulgaris Antigen or Dsg3) in cells known to express its wild-type counterpart. Within 2 d, newborn transgenic animals displayed swelling of their paws, flakiness on their back, and blackening of the tail tip. When analyzed histologically and ultrastructurally, widening of intercellular spaces and disruption of desmosomes were especially striking in the paws and tail. Desmosomes were reduced dramatically in number and were smaller and often peculiar in structure. Immunofluorescence and immunoelectron microscopy revealed no major abnormalities in localization of hemidesmosomal components, but desmosomal components organized aberrantly, resulting in a loss of ultrastructure within the plaque. In regions where desmosome loss was prevalent but where some adhesive structures persisted, the epidermis was thickened, with a marked increase in spinous and stratum corneum layers, variability in granular layer thickness, and parakeratosis in some regions. Intriguingly, a dramatic increase in cell proliferation was also observed concomitant with biochemical changes, including alterations in integrin expression, known to be associated with hyperproliferation. An inflammatory response was also detected in some skin regions. Collectively, these findings demonstrate that a mutation in a desmoglein can perturb epidermal cell-cell adhesion, triggering a cascade of changes in the skin.
Microdissection of neural networks by conditional reporter expression from a Brainbow herpesvirus

Transneuronal transport of neurotropic viruses is widely used to define the organization of neural circuitry in the mature and developing nervous system. However, interconnectivity within complex circuits limits the ability of viral tracing to define connections specifically linked to a subpopulation of neurons within a network. Here we demonstrate a unique viral tracing technology that highlights connections to defined populations of neurons within a larger labeled network. This technology was accomplished by constructing a replication-competent strain of pseudorabies virus (PRV-263) that changes the profile of fluorescent reporter expression in the presence of Cre recombinase (Cre). The viral genome carries a Brainbow cassette that expresses a default red reporter in infected cells. However, in the presence of Cre, the red reporter gene is excised from the genome and expression of yellow or cyan reporters is enabled. We used PRV-263 in combination with a unique lentivirus vector that produces Cre expression in catecholamine neurons. Projection-specific infection of central circuits containing these Cre-expressing catecholamine neurons with PRV-263 resulted in Cre-mediated recombination of the PRV-263 genome and conditional expression of cyan/yellow reporters. Replication and transneuronal transport of recombined virus produced conditional reporter expression in neurons synaptically linked to the Cre-expressing catecholamine neurons. This unique technology highlights connections specific to phenotypically defined neurons within larger networks infected by retrograde transneuronal transport of virus from a defined projection target. The availability of other technologies that restrict Cre expression to defined populations of neurons indicates that this approach can be widely applied across functionally defined systems.
Emotional Intelligence, Leadership Styles Communication Patterns, and Job Satisfaction of College Principals

The quantitative method was adopted in order to measure the relationship among emotional intelligence, leadership styles, communication patterns and job satisfaction of college principals. Through cross sectional research design and by adopting convenient sampling procedure, the research participants (268) of age range between 40 - 65 years were accessed from different colleges of Lahore. The indigenous demographic questionnaire in addition to Multifactor Leadership Questionnaire (MLQ), by Bass and Avolio (2000), Job Satisfaction Survey (JSS), by Spector (1994), Emotional intelligence questionnaire (EI) by Goleman (1995) and Communication Pattern Questionnaire by Christensen and Heavey (1990) was used. The findings revealed that emotional intelligence, emotional management, motivating oneself, empathy and managing others’ emotions were negatively related with passive avoidant leadership and positively correlated with communication patterns and job satisfaction. Also, self-awareness and both transformational and transactional leadership style were found to have a significant positive relationship with communication patterns and job satisfaction. Passive-avoidant leadership style was negatively correlated with communication patterns and job satisfaction. Furthermore, communication patterns were positively correlated with job satisfaction. The years of work experience, education, leadership style, communication patterns and age were found to be successful predictors of job satisfaction of college principals in Lahore. The findings carry strong implication for policy makers and for higher management in order to improve the quality of work life for college principals.
Free fields in skew fields

Building on the work of K. Chiba (J. Algebra 263 (2003), 75-87), we present sufficient conditions for the completion of a division ring with respect to the metric defined by a discrete valuation function to contain a free field, i.e. the universal field of fractions of a free associative algebra. Several applications to division rings generated by torsion-free nilpotent groups, skew Laurent series and related division rings are discussed.

The National Health Insurance Scheme (NHIS) in the Dormaa Municipality, Ghana: Why Some Residents Remain Uninsured?

The paper presents a quantitative investigation on the National Health Insurance Scheme (NHIS) in the Dormaa Municipality, Ghana: Why some residents remain uninsured? Since its implementation a little over a decade now. The aim is to identify the obstacles of enrolment by the public, which would enable policy direction, to ensure that all residents are registered with the scheme. A descriptive and cross-sectional study was conducted between May and July, 2013. Both purposive and simple random sampling techniques were used to select 210 respondents and data obtained through self-administered, and face-to-face interviews guided by structured questionnaire. Chi square (χ2) test of independence was adopted to show the association between socioeconomic and demographic features as well as membership. Findings from the research suggest that residents’ decision to enrol is significantly associated with gender, education, number of children, place of residence, employment and income. It was also observed that membership is highly affected by premium level. The discussion of the findings and recommendations offered, if incorporated into the policy guideline of NHIS, could maintain, and at the same time increase enrolment level. This would guarantee quality and affordable basic health care protection for the good people of Ghana.
