A supply chain network game theory model with product differentiation, outsourcing of production and distribution, and quality and price competition

In this paper, we develop a supply chain network game theory model with product differentiation, possible outsourcing of production and distribution, and quality and price competition. The original firms compete with one another in terms of in-house quality levels and product flows, whereas the contractors, aiming at maximizing their own profits, engage in competition for the outsourced production and distribution in terms of prices that they charge and their quality levels. The solution of the model provides each original firm with its optimal in-house quality level as well as its optimal in-house and outsourced production and shipment quantities that minimize the total cost and the weighted cost of disrepute, associated with lower quality levels and the impact on a firm’s reputation. The governing equilibrium conditions of the model are formulated as a variational inequality problem. An algorithm, which provides a discrete-time adjustment process and tracks the evolution of the product flows, quality levels, and prices over time, is proposed and convergence results given. Numerical examples are provided to illustrate how such a supply chain network game theory model can be applied in practice. The model is relevant to products ranging from pharmaceuticals to fast fashion to high technology products.
Semantic Similarity of Arabic Sentences with Word Embeddings

Semantic textual similarity is the basis of countless applications and plays an important role in diverse areas, such as information retrieval, plagiarism detection, information extraction and machine translation. This article proposes an innovative word embedding-based system devoted to calculate the semantic similarity in Arabic sentences. The main idea is to exploit vectors as word representations in a multidimensional space in order to capture the semantic and syntactic properties of words. IDF weighting and Part-of-Speech tagging are applied on the examined sentences to support the identification of words that are highly descriptive in each sentence. The performance of our proposed system is confirmed through the Pearson correlation between our assigned semantic similarity scores and human judgments.
The Inside-Out Prison Exchange Program: Attitudes Towards Prisoners as Reported by College Students

The Inside-Out Prison Exchange Program involves students from Georgia Southern University and inmates from Smith State Prison who interact and hope to receive a deeper understanding of the justice system through experiential learning. This style of learning has demonstrated greater effectiveness in learning outcomes and a more positive student experience compared to classical, lecture-based learning. No previous research has compared changes in perceptions of students in the Inside-Out Program to a lecture based course of the same content. The purpose of this study was to investigate changes in students’ attitudes towards prisoners over eight weeks between participants in the InsideOut Program and a corrections class. In opposition to previous research, no significant differences were reported in attitudes towards prisoners between groups. Future investigations should continue to examine the transformed opinions of students in experiential and classical learning courses, while using a larger sample size and a longer time period between assessments.

Frequencies and Specificities of “Enzyme-Only” Detected Erythrocyte Alloantibodies in Patients Hospitalized in Austria: Is an Enzyme Test Required for Routine Red Blood Cell Antibody Screening?

The aim of this study was to determine the frequencies and specificities of “enzyme-only” detected red blood cell (RBC) alloantibodies in the routine antibody screening and antibody identification in patients hospitalized in Austria. Routine blood samples of 2420 patients were investigated. The antibody screening was performed with a 3-cell panel in the low-ionic strength saline- (LISS-) indirect antiglobulin test (IAT) and with an enzyme-pretreated (papain) 3-cell panel fully automated on the ORTHO AutoVue Innova System. The antibody identification was carried out manually with an 11-cell panel in the LISS-IAT and with an enzyme-pretreated (papain) 11-cell panel. In total 4.05% (n = 98) of all patients (n = 2420) had a positive RBC antibody screening result. Of them 25.51% (25/98) showed “enzyme-only” detected specific or nonspecific RBC alloantibodies. Rhesus and Lewis system antibodies were found the only specificities of “enzyme-only” RBC alloantibodies: all in all 4.8% (4/98) were detected with anti-E, 3.06% (3/98) with anti-Lea, 3.06% (3/98) with anti-D after anti-D prophylaxis and 1.02% (1/98) with anti-e. In total, 14.29% (14/98) showed a nonspecific RBC alloantibody result with the enzyme test. The results of the present study demonstrate that a high number of unwanted positive reactions with the enzyme technique overshadows the detection of “enzyme-only” RBC alloantibodies.

Measurement errors when estimating the vertical jump height with flight time using photocell devices: the example of Optojump

Common methods to estimate vertical jump height (VJH) are based on the measurements of flight time (FT) or vertical reaction force. This study aimed to assess the measurement errors when estimating the VJH with flight time using photocell devices in comparison with the gold standard jump height measured by a force plate (FP). The second purpose was to determine the intrinsic reliability of the Optojump photoelectric cells in estimating VJH. For this aim, 20 subjects (age: 22.50±1.24 years) performed maximal vertical jumps in three modalities in randomized order: the squat jump (SJ), counter-movement jump (CMJ), and CMJ with arm swing (CMJarm). Each trial was simultaneously recorded by the FP and Optojump devices. High intra-class correlation coefficients (ICCs) for validity (0.98-0.99) and low limits of agreement (less than 1.4 cm) were found; even a systematic difference in jump height was consistently observed between FT and double integration of force methods (-31% to -27%; p<0.001) and a large effect size (Cohen’s d>1.2). Intra-session reliability of Optojump was excellent, with ICCs ranging from 0.98 to 0.99, low coefficients of variation (3.98%), and low standard errors of measurement (0.8 cm). It was concluded that there was a high correlation between the two methods to estimate the vertical jump height, but the FT method cannot replace the gold standard, due to the large systematic bias. According to our results, the equations of each of the three jump modalities were presented in order to obtain a better estimation of the jump height.
SETS: Stochastic execution time scheduling for multicore systems by joint state space and Monte Carlo

The advent of multicore platforms has renewed the interest in scheduling techniques for real-time systems. Historically, ‘scheduling decisions’ are implemented considering fixed task execution times, as for the case of Worst Case Execution Time (WCET). The limitations of scheduling considering WCET manifest in terms of under-utilization of resources for large application classes. In the realm of multicore systems, the notion of WCET is hardly meaningful due to the large set of factors influencing it. Within soft real-time systems, a more realistic modeling approach would be to consider tasks featuring varying execution times (i.e. stochastic). This paper addresses the problem of stochastic task execution time scheduling that is agnostic to statistical properties of the execution time. Our proposed method is orthogonal to any number of linear acyclic task graphs and their underlying architecture. The joint estimation of execution time and the associated parameters, relying on the interdependence of parallel tasks, help build a ‘nonlinear Non-Gaussian state space’ model. To obtain nearly Bayesian estimates, irrespective of the execution time characteristics, a recursive solution of the state space model is found by means of the Monte Carlo method. The recursive solution reduces the computational and memory overhead and adapts statistical properties of execution times at run time. Finally, the variable laxity EDF scheduler schedules the tasks considering the predicted execution times. We show that variable execution time scheduling improves the utilization of resources and ensures the quality of service. Our proposed new solution does not require any a priori knowledge of any kind and eliminates the fundamental constraints associated with the estimation of execution times. Results clearly show the advantage of the proposed method as it achieves 76% better task utilization, 68% more task scheduling and deadline miss reduction by 53% compared to current state-of-the-art methods.
Perks and Excess : Evidence from the New Executive Compensation Disclosure Rules *

In December 2006, the Securities and Exchange Commission issued rules requiring enhanced disclosure of perquisites to managers in public U.S. firms. We use this ruling to shed light on the role of perquisites in executive compensation. In a sample of 361 public firms that were subject to the rule, we find that firms responded to the rule by disclosing significantly larger amounts of perks. The level of disclosed perks under the new rule is higher in firms that have fewer growth opportunities and larger amounts of free cash flow. Further, the market reacts negatively to the announcement of these perks, especially in firms that disclose large amounts of perks for the first time. Our results are in line with the argument that perks are an excess that reduces shareholder value.
Pricing Corporate Bonds with Risk Adjustable Default Barrier

This paper develops a corporate bond valuation model that incorporates a default barrier with dynamics depending on stochastic interest rates and variance of the corporate bond function. The volatility of the firm value affects the level of the barrier over time through the variance of the corporate bond function and its contribution to the barrier's dynamics is adjusted by a free parameter. We derive a closed-form solution of the corporate bond price as a function of firm value and interest rate, with time-dependent model parameters governing the dynamics of firm value and interest rate. The numerical results calculated from the solution show that the dynamics of the barrier has material impact on the term structures of credit spreads. The model incorporating the risk adjustable default barrier, deviations from the absolute priority rule, and time-dependent model parameters is capable of producing diverse shape of term structures of credit spreads. This model provides new insight for future research on corporate bonds analysis and credit risk modelling.
Cardiac Fibrosis Alleviated by Exercise Training Is AMPK-Dependent

Regular exercise can protect the heart against external stimuli, but the mechanism is not well understood. We determined the role of adenosine monophosphate-activated protein kinase (AMPK) in regulating swimming exercise-mediated cardiac protection against β-adrenergic receptor overstimulation with isoproterenol (ISO) in mice. Ten-week-old AMPKα2+/+ and AMPKα2-knockout (AMPKα2-/-) littermates were subjected to 4 weeks of swimming training (50 min daily, 6 days a week) or housed under sedentary conditions. The mice received daily subcutaneous injection of ISO (5 mg/kg/d), a nonselective β-adrenergic receptor agonist, during the last 2 weeks of swimming training. Swimming training alleviated ISO-induced cardiac fibrosis in AMPKα2+/+ mice but not AMPKα2-/- mice. Swimming training activated cardiac AMPK in AMPKα2+/+ mice. Furthermore, swimming training attenuated ISO-induced production of reactive oxygen species (ROS) and expression of NADPH oxidase and promoted the expression of antioxidant enzymes in AMPKα2+/+ mice but not AMPKα2-/- mice. In conclusion, swimming training attenuates ISO-induced cardiac fibrosis by inhibiting the NADPH oxidase–ROS pathway mediated by AMPK activation. Our findings provide a new mechanism for the cardioprotective effects of exercise.
Field Theory of Non-Equilibrium Systems

The physics of non-equilibrium many-body systems is a rapidly expanding area of theoretical physics. Traditionally employed in laser physics and superconducting kinetics, these techniques have more recently found applications in the dynamics of cold atomic gases, mesoscopic and nano-mechanical systems, and quantum computation. This book provides a detailed presentation of modern non-equilibrium field-theoretical methods, applied to examples ranging from biophysics to the kinetics of superfluids and superconductors. A highly pedagogical and self-contained approach is adopted within the text, making it ideal as a reference for graduate students and researchers in condensed matter physics. In this Second Edition, the text has been substantially updated to include recent developments in the field such as driven-dissipative quantum systems, kinetics of fermions with Berry curvature, and Floquet kinetics of periodically driven systems, among many other important new topics. Problems have been added throughout, structured as compact guided research projects that encourage independent exploration.
Maternal bereavement shortly before or during pregnancy and risk of postpartum psychotic illness: a population-based study from Denmark and Sweden

Purpose: Postpartum psychosis is a rare but severe complication following childbirth, with unknown etiology. This study investigated whether the death of a close family member — a source of severe stress — the year before or during pregnancy was associated with an increased risk of psychotic illness in the postpartum period among women without and with a history of psychiatric disorder. Methods: We studied live births in Denmark during 1978–2008 and births in Sweden during 1973–2006 (n=5,246,978). Information on death of women’s relatives and partners and sociodemographic, health-, and pregnancy-related factors was obtained through linkage with nationwide registries. Results: The death of a close relative the year before or during pregnancy was not associated with psychotic illness during the first 90 days postpartum among women without (adjusted HR 1.02, 95% CI 0.76–1.37) or with a history of psychiatric disorder (HR 0.96, 95% CI 0.74–1.25). Similarly, there was no association between bereavement and risk of postpartum psychosis according to the timing of the loss (the year before or during pregnancy), the relative’s cause of death (natural or unnatural), or the woman’s relationship to the deceased (parent/sibling or partner/older child). Conclusions: Death of a close relative, one of the most severe sources of stress, before or during pregnancy was not associated with postpartum psychosis. Therefore, these data do not support the hypothesis that severely stressful life events, such as bereavement around the time of pregnancy, are associated with postpartum psychosis.
Multiple One-Shots for Utilizing Class Label Information

The One-Shot Similarity (OSS) kernel [3, 4] has recently been introduced as a means of boosting the performance of face recognition systems. Given two vectors, their One-Shot Similarity score (Fig. 1) reflects the likelihood of each vector belonging to the same class as the other vector and not in a class defined by a fixed set of “negative” examples. In this paper we explore how the One-Shot Similarity may nevertheless benefit from the availability of such labels. (a) we present a system utilizing identity and pose information to improve facial image pair-matching performance using multiple One-Shot scores; (b) we show how separating pose and identity may lead to better face recognition rates in unconstrained, “wild” facial images; (c) we explore how far we can get using a single descriptor with different similarity tests as opposed to the popular multiple descriptor approaches; and (d) we demonstrate the benefit of learned metrics for improved One-Shot performance.
Coupling and Harnack inequalities for Sierpiński carpets

Uniform Harnack inequalities for harmonic functions on the preand graphical Sierpinski carpets are proved using a probabilistic coupling argument. Various results follow from this, including the construction of Brownian motion on Sierpinski carpets embedded in Rd , d ≥ 3, estimates on the fundamental solution of the heat equation, and Sobolev and Poincare inequalities. The Sierpinski carpets (SCs) we will study are generalizations of the Cantor set. Let F0 = [0, 1] be the unit cube in R, d ≥ 2, centered at z0 = (1/2, . . . , 1/2). Let k, a be integers with 1 ≤ a < k and a + k even. Divide F0 into k equal subcubes, remove a central block of a subcubes, and let F1 be what remains: thus F1 = F0 − ((k − a)/2k, (k + a)/2k). Now repeat this operation on each of the k − a remaining subcubes to obtain F2. Iterating, we obtain a decreasing sequence of closed sets Fn; then F = ⋂∞ n=0 Fn is a Sierpinski carpet and has Hausdorff dimension df = df (F ) = log(k − a)/ log(k). (When d = 2, k = 3, and a = 1, we get the usual Sierpinski carpet.) Let Fn = kFn ⊂ [0,∞), and define the pre-Sierpinski carpet by F = ⋃∞ n=1 Fn (see [10]). The graphical Sierpinski carpet is the graph G = (V,E) with vertex set V = (z0 + Z) ∩ F and edge set E = { {x, y} ∈ V : |x− y| = 1}. Thus int(F ) is a domain in R with a large-scale structure which mimics the small-scale structure of F . We are interested in the behavior of solutions of the Laplace and heat equations on F , F , and G. One reason for this is applications to “transport phenomena” in disordered media (see [6]); another is the new type of behavior of the heat kernel on these spaces. Let W be Brownian motion on F with normal reflection on ∂F , and let q(t, x, y) be the transition density of W , so that q solves the heat equation on F with Neumann boundary conditions on ∂F . 1991 Mathematics Subject Classification.

Cleft Palate Cells Can Regenerate a Palatal Mucosa in vitro

Cleft palate repair leaves full-thickness mucosal defects on the palate. Healing might be improved by implantation of a mucosal substitute. However, the genetic and phenotypic deviations of cleft palate cells may hamper tissue engineering. The aim of this study was to construct mucosal substitutes from cleft palate cells, and to compare these with substitutes from normal palatal cells, and with native palatal mucosa. Biopsies from the palatal mucosa of eight children with cleft palate and eight age-matched control individuals were taken. Three biopsies of both groups were processed for (immuno)histochemistry; 5 were used to culture mucosal substitutes. Histology showed that the substitutes from cleft-palate and non-cleft-palate cells were comparable, but the number of cell layers was less than in native palatal mucosa. All epithelial layers in native palatal mucosa and mucosal substitutes expressed the cytokeratins 5, 10, and 16, and the proliferation marker Ki67. Heparan sulphate and decorin were present in the basal membrane and the underlying connective tissue, respectively. We conclude that mucosal cells from children with cleft palate can regenerate an oral mucosa in vitro.
Cu–Ni–Mn Alloy Wires, with Improved Sub-micrometric Surfaces, Used as LENR Device by New Transparent, Dissipation-type Calorimeter

Starting in February 2011, we studied the feasibility of new nickel-based alloys that are able to absorb significant amounts of hydrogen (H2) and/or deuterium (D2) and might, in principle, possibly generate anomalous thermal effects at temperatures >100◦C. The interest in Ni alloys comes in part because there is the possibility to use H2 instead of expensive D2. Moreover, a crosscomparison of results using H2 instead of D2 can be made and could help the understanding of the phenomena involved (and the possible nuclear origin). © 2014 ISCMNS.

Lubrication Tests to Support Optimal Performance Design Guidelines for Thrust Slide-Bearings in Scroll Compressors

This study focuses on experimental verification of the optimal performance design guideline in lubrication for the thrust slide-bearings in scroll compressors. The auhtors’ previously derived theoretical analysis using the average Reynolds equation and the solid contact theory, when applied to a cylindrical rigid thrust plate model with a small fixed wedge angle at its pheriphery, predicted a dramatic decrease in the friction power loss with increasing outerto-inner radius ratio and determined a minimum value at a certain value of the radius ratio. For experimental confirmation of this predicted optimal lubrication performance, a cylindrical-model of the thrust slide-bearing, submerged in a refrigerant oil POE (polyol ester), was operated under a pressurized condition of 0.6 MPa using R410A as the pressurizing gas, over a wide range of orbiting speeds from 1200 rpm to 6000 rpm for a fixed orbiting radius of 3.0 mm. The resulting measured data agreed well with the predicted tendency that the lubrication of the thrust slide-bearing is substantially improved by increasing the outer radius. As was theoretically predicted, the minimum loss with a radius ratio of about 2.1 at an operating speed of 3600 rpm, a significant 80% reduction relative to the usual conventional design ratio.
