Algorithms for higher-order derivatives of Erlang C function

In this paper we analyze the partial derivatives of any order of the continued Erlang C function in the number of servers. For the numerical computation of those derivatives, several algorithms are proposed and compared in terms of stability, efficiency and precision. This study concludes that a recursive matrix relation presented in a previous work [4, 5], may be used for the establishment of a simple and reliable algorithm having the best performance considering the trade-off of the different criteria. Some computational results are presented and discussed. A conjecture about the convexity of the first derivative is supported by these computational results.
The roles of hotel identification on customer‐related behavior

Purpose – Past researches have not explored the roles of staff's hotel identification on customer‐related behaviors and the relationship between hotel identification inducing factors (trust in supervisor, job satisfaction, perceived external prestige) and hotel identification. The purpose of this paper is to examine the roles of staff's hotel identification as a mediator of the relationship between hotel identification inducing factors and customer‐related behaviors. Through reviewing the existing literature concerned, the authors propose a research model involving staff's trust in the supervisor, job satisfaction, perceived external prestige, hotel identification, organization citizenship behavior, and customer satisfaction behavior and test it.Design/methodology/approach – Hotel samples were from the south‐west area of Korea. Questionnaires were given to 250 staff of the hotels and 224 were returned with no problems. The sample was used to purify the measures and test their convergent and discriminant v.
Tear and Serum Eosinophil Cationic Protein Levels in Seasonal Allergic Conjunctivitis

Background/Purpose Eosinophil cationic protein (ECP) levels in tear fluid and sera of patients with seasonal allergic conjunctivitis (SAC) were measured to assess local and systemic eosinophilic activity in SAC. The correlation between ECP levels and disease activity was evaluated. Methods Tears and sera were collected from 21 patients with SAC and 13 healthy control subjects. ECP levels in tears and sera were measured before and 4 weeks after treatment with 0.1% lodoxamide eyedrops. Clinical signs and symptoms of SAC were scored and the correlation of ECP levels with the clinical scores was evaluated. Results Tear and serum levels of ECP were significantly increased (p=0.01, p=0.02, respectively) in patients with SAC compared with the control subjects, but ECP levels were not correlated with the severity of the disease. Following treatment with topical 0.1% lodoxamide eyedrops, the mean level of ECP in tears decreased significantly (p=0.02), whereas no significant change was observed in serum ECP levels. Furthermore, a significant decrease in clinical signs and symptoms scores was found after treatment (both p<0.0001). Conclusions Increased serum and tear ECP levels in patients with SAC confirms that both local and systemic eosinophil activation occurs in SAC. However, clinical signs and symptoms of SAC were not found to be correlated with the degree of eosinophilic activity. Thus ECP does not seem to have an important role in clinical manifestations of SAC.
Journal Publication of Material Presented at an Annual AERA Meeting

The two most important media of scientific communication, national meetings and journal articles, are closely related. In most disciplines much of the work which is presented at national meetings is later submitted for journal publication (Orr, 1961; American Psychological Association, 1963; Lin, Garvey and Nelson, 1970). Authors of contributed papers at the 1968 AERA meeting were no different from authors of presentations of other national meetings. For example 76% of the contributed paper authors at the time of the meeting planned publication of their work in journal article form (Nelson, Garvey, and Lin, 1970). This article deals with the journal publication fate of the material presented at the 1968 AERA meeting during the subsequent two years.

Convergent Sequences of Dense Graphs II. Multiway Cuts and Statistical Physics

We consider sequences of graphs (Gn) and dene various notions of convergence related to these sequences including \left-convergence," dened in terms of the densities of homomorphisms from small graphs into Gn, and \right-convergence," dened in terms of the densities of homomorphisms from Gn into small graphs. We show that right-convergence is equivalent to left-convergence, both for simple graphs Gn, and for graphs Gn with nontrivial nodeweights and edgeweights. Other equivalent conditions for convergence are given in terms of fundamental notions from combinatorics, such as maximum cuts and Szemer edi partitions, and fundamental notions from statistical physics, like energies and free energies. We thereby relate local and global properties of graph sequences. Quantitative forms of these results express the relationships among dierent measures of similarity of large graphs.
Transition-based Dependency Parsing Using Two Heterogeneous Gated Recursive Neural Networks

Recently, neural network based dependency parsing has attracted much interest, which can effectively alleviate the problems of data sparsity and feature engineering by using the dense features. However, it is still a challenge problem to sufficiently model the complicated syntactic and semantic compositions of the dense features in neural network based methods. In this paper, we propose two heterogeneous gated recursive neural networks: tree structured gated recursive neural network (Tree-GRNN) and directed acyclic graph structured gated recursive neural network (DAG-GRNN). Then we integrate them to automatically learn the compositions of the dense features for transition-based dependency parsing. Specifically, Tree-GRNN models the feature combinations for the trees in stack, which already have partial dependency structures. DAG-GRNN models the feature combinations of the nodes whose dependency relations have not been built yet. Experiment results on two prevalent benchmark datasets (PTB3 and CTB5) show the effectiveness of our proposed model.
Anatomical factors determining surgical decision-making in patients with transposition of the great arteries with left ventricular outflow tract obstruction.

OBJECTIVES Transposition of the great arteries (TGA) and left ventricular outflow tract obstruction (LVOTO) with or without ventricular septal defect have multiple surgical treatment options. We sought to identify pre- and intraoperative factors that determine the timing of repair, procedure type and subsequent LVOT outcome. METHODS Twenty-eight (8.2% of all TGA) patients with TGA with LVOTO (double outlet ventricle, n = 5, TGA/intact septum, n = 1) between 2000 and 2012 were reviewed. Anatomical factors were identified by prerepair echocardiography. LVOTO complexity was characterized by the degree of obstruction (0 = none, 0.33 = mild, 0.66 moderate and 1 = severe) at various levels: pulmonary valve (PV) dysplasia/hypoplasia, posterior deviation of the infundibular septum, fibromuscular ridge, tissue tag and abnormal chordal attachment. Summation of the obstruction score, at each level, yielded the LVOT complexity score. The descriptive analysis of intraoperative decision-making at late repair was performed. RESULTS OPERATIONS early arterial switch operation (ASO) + LVOT resection (n = 9, 32%), late ASO + LVOT resection (n = 3, 10%), Nikaidoh (n = 8, 29%), Rastelli (n = 6, 21%), single-ventricle palliation (n = 2, 7%). The primary LVOT obstruction mechanism was posterior deviation of the infundibular septum (n = 16, 57%) and PV dysplasia (n = 6, 21%). The early ASO group had a lower PV complexity score (0.42 ± 0.22 vs 0.96 ± 0.55, P = 0.007), tissue tag score (0.03 ± 0.15 vs 0.26 ± 0.34, P = 0.018) and LVOT complexity score (2.11 ± 0.86 vs 3.2 ± 0.96, P = 0.006). The LVOT complexity score in the Nikaidoh group was higher than in the late ASO group (P = 0.019). Of 16 candidates for the Nikaidoh procedure, 6 patients underwent a Rastelli operation due to coronary artery patterns (single coronary, n = 3, 1RL-2Cx, n = 2 or an abnormal left anterior descending coronary artery course, n = 1). Two patients underwent single-ventricle palliation due to the interference of essential chordae. All patients survived the operation. The 3-year survival was 96%. One patient who underwent late ASO required re-LVOT resection. CONCLUSIONS A newly developed scoring system, the LVOT complexity score, helped to quantify the LVOT complexity and was correlated with our choice of the surgical procedure of TGA with LVOTO. The current strategy achieved reasonable survival and LVOT outcome with three quarters of the patients having an anatomically aligned LVOT. The coronary anatomy pattern was the primary determinant in the decision-making between the Nikaidoh procedure and the Rastelli operation.
A nonlinear optimization algorithm for asymmetric FIR digital filters

An enhanced version of a previously presented nonlinear optimization algorithm is presented for designing asymmetric FIR digital filters. The asymmetric FIR filter design (AFFD) algorithm is based on the iterative use of the generalized multiple exchange (GME) algorithm. The enhanced version of the AFFD algorithm uses a line search of the nonlinear Lagrangian to determine the iteration step size. This greatly enhances the convergence properties of the AFFD algorithm. The AFFD algorithm can design optimal multiband filters that simultaneously meet specifications on the group delay and the magnitude of the frequency response.
Genetic Analysis of the Polyomavirus DnaJ Domain

ABSTRACT Polyomavirus T antigens share a common N-terminal sequence that comprises a DnaJ domain. DnaJ domains activate DnaK molecular chaperones. The functions of J domains have primarily been tested by mutation of their conserved HPD residues. Here, we report detailed mutagenesis of the polyomavirus J domain in both large T (63 mutants) and middle T (51 mutants) backgrounds. As expected, some J mutants were defective in binding DnaK (Hsc70); other mutants retained the ability to bind Hsc70 but were defective in stimulating its ATPase activity. Moreover, the J domain behaves differently in large T and middle T. A given mutation was twice as likely to render large T unstable as it was to affect middle T stability. This apparently arose from middle T's ability to bind stabilizing proteins such as protein phosphatase 2A (PP2A), since introduction of a second mutation preventing PP2A binding rendered some middle T J-domain mutants unstable. In large T, the HPD residues are critical for Rb-dependent effects on the host cell. Residues Q32, A33, Y34, H49, M52, and N56 within helix 2 and helix 3 of the large T J domain were also found to be required for Rb-dependent transactivation. Cyclin A promoter assays showed that J domain function also contributes to large T transactivation that is independent of Rb. Single point mutations in middle T were generally without effect. However, residue Q37 is critical for middle T's ability to form active signaling complexes. The Q37A middle T mutant was defective in association with pp60c-src and in transformation.
Protein Antigenic Structures Recognized by T Cells; Potential Applications to Vaccine Design

In summary, our results using the model protein antigen myoglobin indicated, in concordance with others, that helper T lymphocytes recognize a limited number of immunodominant antigenic sites of any given protein. Such immunodominant sites are the focus of a polyclonal response of a number of different T cells specific for distinct but overlapping epitopes. Therefore, the immunodominance does not depend on the fine specificity of any given clone of T cells, but rather on other factors, either intrinsic or extrinsic to the structure of the antigen. A major extrinsic factor is the MHC of the responding individual, probably due to a requirement for the immunodominant peptides to bind to the MHC of presenting cells in that individual. In looking for intrinsic factors, we noted that both immunodominant sites of myoglobin were amphipathic helices, i.e., helices having hydrophilic and hydrophobic residues on opposite sides. Studies with synthetic peptides indicated that residues on the hydrophilic side were necessary for T-cell recognition. However, unfolding of the native protein was shown to be the apparent goal of processing of antigen, presumably to expose something not already exposed on the native molecule, such as the hydrophobic sides of these helices. We propose that such exposure is necessary to interact with something on the presenting cell, such as MHC or membrane, where we have demonstrated the presence of antigenic peptides by blocking of presentation of biotinylated peptide with avidin. The membrane may serve as a short-term memory of peptides from antigens encountered by the presenting cell, for dynamic sampling by MHC molecules to be available for presentation to T cells. These ideas, together with the knowledge that T-cell recognition required only short peptides and therefore had to be based only on primary or secondary structure, not tertiary folding of the native protein, led us to propose that T-cell immunodominant epitopes may tend to be amphipathic structures. An algorithm to search for potential amphipathic helices from sequence information identified 18 of 23 known immunodominant T-cell epitopes from 12 proteins (p less than 0.001). Another statistical approach confirmed the importance of amphipathicity and also supported the importance of helical structure that had been proposed by others. It suggested that peptides able to form a stable secondary structure, especially a helix, more commonly formed immunodominant epitopes. We used this approach to predict potential immunodominant epitopes for induction of T-cell immunity in proteins of clinical relevance, such as the malarial circumsporozoite protein and the AIDS viral envelope.

2D geometrical based channel model including rain fading effect

This paper investigates the distribution of scatteres i.e trees and its effect during the rain event in the outdoor urban scenario. The 2D elliptical geometry based single bounce model is considered for microcell environment in which the multipath reflection is accounted by the presence of trees that are uniformly distributed within the elliptical region. Analytical expressions for the joint Angle of Arrival (AoA)/Time of Arrival (ToA) probability density functions (pdf) and marginal AoA and ToA (pdfs) have been derived for the proposed model. We found that the pdf of ToA at the Mobile station is directly affected by the different rain event. The derived formulas can be used further for evaluating the spatio-temporal characteristics of the mobile channel.
Neighborhood Environmental Satisfaction, Victimization, and Social Participation as Determinants of Perceived Neighborhood Safety

This research examines the effect of overall neighborhood satisfac-tion, victimization, and social participation on perceived neighborhood safety. It systematically tests the relative importance of victimization, concern with neigh-borhood "environmental" quality, and social integration into the community in predicting fear of crime. Our research incorporates three aspects into a single model that predicts the level of fear of crime experienced by local community residents. Fear of crime is measured in terms of perceived risks in various circumstances in the neighborhood of residence. As such, a measure of fear of crime can be seen as a measure of perceived neighborhood safety. Results suggest that those who exhibit higher levels of satisfaction with the neighborhood environment tend to express higher perceived levels of neighborhood safety. Property victimization, not personal victimization, is found to have an impact on residents' perception of neighborhood safety. In contrast, social participation does not seem to be related to perceived neighborhood safety. The result implies that improving the quality of neighborhood environmental characteristics will increase residents' concern with the appearance of the neighborhood along with their concerns about the quality of people who live there, which in turn enhances higher perceived levels of neighborhood safety.
Automatic locating the centromere on human chromosome pictures

Many genetic disorders or possible abnormalities that may occur in the future generations can be predicted through analyzing the shape and morphological characteristics of the chromosomes. Karyotype (a systemized array of the human chromosomes obtained from a single cell either by drawing or by photography using a light microscope is often used for this purpose. To make a Karyotype it is necessary to identify each one of the 24 chromosomes (22 autosomal and a pair of sex chromosomes) from the microscopic images. The first step to automate this process is then to define the morphological and band pattern based features for each chromosome. An important class of morphological features includes those defined with respect to the location of the chromosome's centromere (part of the chromosome that divides it to the long and short arms). Therefore, localization of centromere is an initial step in designing an automatic karyotyping system. In this paper, an effective algorithm for chromosome image processing and automatic centromere locating is presented The procedure is based on the calculation and analyzing the vertical and horizontal projection vectors of the binary image of the chromosome. The binary image is obtained using the thresholding of the input image after histogram modification and analyzing. When applied to the real chromosome images supplied by the Cytogenetic Laboratory of the Cancer Institute of the Imam hospital in Tehran, an average accuracy of 96% for Centromere locating is achieved.
Field Dependence and the Role of Visual Frameworks in the Perception of Size

The extent to which apparent size is relationally determined has been studied by Rock and Ebenholtz and by Wenderoth, who came to widely differing conclusions as to the magnitude of this phenomenon. In both studies, a large range of individual differences was observed. In the present study, an attempt was made to account for variations in the influence of visual contexts on the perception of size by relating them to the cognitive style dimension of field dependence/independence. In two situations, relatively field-dependent observers made size judgments which were influenced by a frame surrounding the target figure, while relatively field-independent observers tended to be less influenced by the frame, making their judgments approximate the retinal size of the target. The results suggest that assessment of the magnitude of the relational determination of apparent size must consider the cognitive style of the observers as well as situational variations.
The Psychology of Good and Evil: Contents

This book gathers together the knowledge gained in a lifelong study of the causes of goodness and evil. Since the 1960s Ervin Staub has studied the roots of helpful, caring, generous, and altruistic behavior in adults and their development in children, as well as passivity in response to others’ need. He has also studied bullying and victimization in schools, as well as youth violence and its prevention. He spent many years studying the origins (and prevention) of human destructiveness, genocide, and mass killing, and he has examined the Holocaust, the genocide of the Armenians, the disappearances in Argentina, the genocide in Rwanda, and other instances. He has applied his work in many real-world settings, in seminars, workshops, lectures, and in consultations with parents and teachers, police officers, and political leaders. He has appeared frequently in the media, since September 11 especially, to explain the causes and prevention of terrorism. Professor Staub has published, in addition to books, many articles and book chapters on these topics. A selection from these is gathered, with new writings added, in The Psychology of Good and Evil. The book presents a broad panorama of the roots of violence and caring and suggests how we can create societies and a world that are caring, peaceful, and harmonious. Two of the important themes of the book are how both evil and goodness evolve, step by step, and the great power of bystanders.

Collaborative hyperparameter tuning

Hyperparameter learning has traditionally been a manual task because of the limited number of trials. Today's computing infrastructures allow bigger evaluation budgets, thus opening the way for algorithmic approaches. Recently, surrogate-based optimization was successfully applied to hyperparameter learning for deep belief networks and to WEKA classifiers. The methods combined brute force computational power with model building about the behavior of the error function in the hyperparameter space, and they could significantly improve on manual hyperparameter tuning. What may make experienced practitioners even better at hyperparameter optimization is their ability to generalize across similar learning problems. In this paper, we propose a generic method to incorporate knowledge from previous experiments when simultaneously tuning a learning algorithm on new problems at hand. To this end, we combine surrogate-based ranking and optimization techniques for surrogate-based collaborative tuning (SCoT). We demonstrate SCoT in two experiments where it outperforms standard tuning techniques and single-problem surrogate-based optimization.
