Recent PHENIX elliptic flow (v2) measurements for identified particles produced in Au+Au and Cu+Cu collisions at are presented and compared to other RHIC measurements. They indicate universal scaling of v2 compatible with partonic collectivity leading to the flow of light, strange and heavy quarks with a common expansion velocity field.
Macrophage recruitment and activation: a model for comparing resistance to Salmonella enteritidis in different broiler breeds.

A model for comparing resistance to Salmonella Enteritidis was evaluated in different broiler breeds. The recruitment and phagocytic activity of peritoneal macrophages were assessed in three different broiler breeds (A, B and C) which are farmed world-wide. Assessment was performed after three days of intraperitoneal (i.p.) administration of 3% Sephadex G-200 (10 ml), initiated at twenty-one days of age, followed by contact with i.p. live S. Enteritidis (10 ml, 1.2 x 10(8) colony forming units/ml) for 45 min. Assessment included determination of the number of i.p. macrophages recruited, the number of i.p. phagocytized S. Enteritidis cells per macrophage, the levels of degranulated i.p. beta-glucuronidase and beta-galactosidase, and the count of surviving S. Enteritidis cells. Confirmation of the significance of the model was obtained by comparing resistance to field infection by S. Enteritidis in the three broiler breeds. The recruitment of i.p. macrophages in response to challenge with Sephadex and S. Enteritidis was significantly higher (P < 0.05) in birds of breed A (mean cumulative i.p. macrophage count, in 10 fields of microscopic slide smear magnified at x1,000, was equal to 81.7), compared to recruitment in birds of breed B (33.3) or breed C (41.2). The mean number of phagocytized S. Enteritidis cells per i.p. macrophage in birds of breed A (2.68) was significantly higher (P < 0.05) than in breed B (0.83) and insignificantly higher (P > 0.05) than in breed C (2.35). In addition, the highest level of recruitment and phagocytic activity of macrophages, in birds of breed A, was associated with a higher significant mean i.p. beta-glucuronidase activity (10,425.5 units/ml) than in breed B (3,438.2 units/ml) or breed C (3,356.94 units/ml) (P < 0.05). Moreover, birds of breed A demonstrated a higher mean i.p. beta-galactosidase activity (2.225 units/ml) than birds of breed B (0.852 units/ml) or breed C (1.852 units/ml) (P > 0.05). The higher level of recruitment and activity of i.p. macrophages and the higher rate of degranulation of i.p. enzymes in breed A were associated with a greater number of surviving i.p. S. Enteritidis cells. In response to outbreaks of S. Enteritidis in the field, the average mortality was significantly higher in flocks of breed A (3.2%) than in flocks of breed B (1.2%) or breed C (0.96%) (P < 0.05). These data provide an indication of the significance of the model in reflecting the differences in resistance of S. Enteritidis of broiler breeds reared in a farm environment.
A Novel Dual Camera Method for Odometric Exteroceptive Relative Localisation

In this paper a new type of sensor data input for mobile robot localisation is proposed. Sensor images are taken from two ground-facing cameras mounted on either side of the robot. The affine transformations between image pairs, computed using the phase correlation method, are used to estimate the motion of the robot. Results on a plain coloured carpeted surface, show that the proposed method provides a truly odometric type sensor data input for mobile robot localisation. Being independent of the kinematics it is resistant to wheel slippage, or other catastrophic failures of kinematic model based methods. A method to calibrate the vision system using a 1D object is also presented.
Identifying important structural characteristics of arsenic resistance proteins by using designed three-stranded coiled coils

Arsenic, a contaminant of water supplies worldwide, is one of the most toxic inorganic ions. Despite arsenic's health impact, there is relatively little structural detail known about its interactions with proteins. Bacteria such as Escherichia coli have evolved arsenic resistance using the Ars operon that is regulated by ArsR, a repressor protein that dissociates from DNA when As(III) binds. This protein undergoes a critical conformational change upon binding As(III) with three cysteine residues. Unfortunately, structures of ArsR with or without As(III) have not been reported. Alternatively, de novo designed peptides can bind As(III) in an endo configuration within a thiolate-rich environment consistent with that proposed for both ArsR and ArsD. We report the structure of the As(III) complex of Coil Ser L9C to a 1.8-Å resolution, providing x-ray characterization of As(III) in a Tris thiolate protein environment and allowing a structural basis by which to understand arsenated ArsR.
A Study on Vehicular Ad Hoc Networks

Vehicular Ad Hoc Networks (VANETs) are special class of Mobile Ad Hoc Networks (MANETs) formed by vehicles equipped with wireless gadgets. The communication in VANET occurs between Vehicle 2 Vehicle mode and Vehicle to road side unit forming an intelligent transport system. Routing plays an important role in forwarding the required data to the nodes or vehicles. In this paper we investigate the performance evaluation of reactive routing protocols such as AODV and DSR and proactive routing protocols such as OLSR in urban city traffic scenario using SUMO and network performance using NS3 to find an appropriate protocol by using network parameters such as packet delivery ratio, throughput and delay. From the simulations we observed that AODV fared well over other routing protocols in VANET scenarios.
Clinical significance of gefitinib antitumor activity in patients with lung adenocarcinoma

Non-small cell lung cancer is a subtype of adenocarcinoma, which has previously shown positive responses to gefitinib. The aim of the current study was to determine a clinical profile of gefitinib-induced disease controls for patients with lung adenocarcinoma. Retrospective evaluation of the clinical characteristics of 52 lung adenocarcinoma patients, enrolled at the Zhejiang Cancer Hospital (Hangzhou, China) between October 2004 and August 2008, was undertaken. All patients received gefitinib (250 mg/day orally) until disease progression or until an unacceptable toxicity was observed. Of the 52 patients, complete response (CR) and partial response (PR) rates were 23.1% (12/52) and 57.7% (30/52), respectively. An additional 19.2% (10/52) of patients demonstrated stable disease (SD) after three months of treatment with gefitinib. Disease control was observed in the primary lesion, and tumor metastasis to the lungs, brain, adrenal glands, pleura, peritoneum, pericardium, bone and lymph nodes was identified. The one-year progression-free survival (PFS) and overall survival (OS) rates were 74.8 and 78.0%, respectively. Multivariate analysis revealed that female patients were associated with significantly longer survival times when compared with males (hazard ratio, 0.077; 95% confidence interval [CI], 0.007–0.083; P=0.035). One-year PFS and OS rates in CR, PR and SD patients were 77.8, 73.9 and 33.3%, and 89.2, 79.8 and 33.7%, respectively, although neither difference was identified to be statistically significant. In addition, the median OS of SD patients was 12 months (95% CI, 7.2–16.8 months). Brain metastasis was the major site of disease progression (23.1%). Gefitinib treatment for patients with lung adenocarcinoma showed a marked long-term survival benefit, even in SD patients. However, further studies are required to analyze the efficacy of gefitinib in penetrating the blood-brain barrier in order to prolong PFS in patients with lung adenocarcinoma.
On Nonexclusive Membership in Competing Joint Ventures

We evaluate the competitive and governance effects of "duality. " Duality refers to the joint membership (e.g., by banks) in competing associations or joint ventures (e.g., Visa and MasterCard). We first show that the not-for-profit nature of the associations along with the usage-based fees they charge yield productive efficiency. We then analyze the impact of (i) membership exclusivity, when the associations remain not-for-profit, and (ii) the conversion into for-profit systems. We illustrate the results in the case of a double-differentiation model that is of independent interest. Finally, we discuss extensions to (i) endogenous system differentiation, and (ii) agency considerations. Copyright 2003 by the RAND Corporation.
An Unsupervised and Data-Driven Approach for Spell Checking in Vietnamese OCR-scanned Texts

OCR (Optical Character Recognition) scanners do not always produce 100% accuracy in recognizing text documents, leading to spelling errors that make the texts hard to process further. This paper presents an investigation for the task of spell checking for OCR-scanned text documents. First, we conduct a detailed analysis on characteristics of spelling errors given by an OCR scanner. Then, we propose a fully automatic approach combining both error detection and correction phases within a unique scheme. The scheme is designed in an unsupervised & data-driven manner, suitable for resource-poor languages. Based on the evaluation on real dataset in Vietnamese language, our approach gives an acceptable performance (detection accuracy 86%, correction accuracy 71%). In addition, we also give a result analysis to show how accurate our approach can achieve.
Life-Threatening Complications of Hormonal Contraceptives: A Case History

We present a case with the rare combination of thrombotic and hemorrhagic complications of oral contraceptives. A healthy 40-year-old woman suffered from cardiac arrest due to massive pulmonary embolism, caused by oral contraceptives and immobilization during a flight. After successful resuscitation, obstructive shock necessitated thrombolysis and thereafter heparin. Anticoagulation was complicated by internal bleeding from contraceptive related hepatic adenoma. She underwent arterial embolisation, and anticoagulation was continued. On day 18, she was discharged in a good condition. Hepatic adenomas are a potential source of internal bleeding in women using oral contraceptives requiring anticoagulation. Signs of internal bleeding in such patients should prompt immediate abdominal ultrasound examination.
Recombination dynamics in wurtzite InP nanowires

We report time-resolved photoluminescence investigations of as-grown wurtzite InP nanowires $({d}_{\text{av}}=16\text{ }\text{nm})$ on a (111) silicon substrate as a function of emission energy, temperature, and excitation fluence. The observed luminescence transients are well described by a biexponential decay process, with ${\ensuremath{\tau}}_{\mathrm{fast}}\ensuremath{\sim}0.3\char21{}0.7\phantom{\rule{0.3em}{0ex}}\mathrm{ns}$ and ${\ensuremath{\tau}}_{\mathrm{slow}}\ensuremath{\sim}2\char21{}5\phantom{\rule{0.3em}{0ex}}\mathrm{ns}$, which does not originate from band bending induced by surface states. The trends associated with the decay characteristics instead point to size-dependent localization effects in the narrow nanowires.
Trust and Professional Skepticism in the Relationship between Auditors and Clients: Overcoming the Dichotomy Myth

ABSTRACT: This study empirically investigates the relationship between auditors' identification-based trust in client firms' managers (CEOs/CFOs) and their perceptions of auditors' professional skepticism. We employ a multimethod approach broken down into two studies. First, in Study 1, we approached auditors and clients using narrative interviews in order to identify the working definitions of interpersonal trust and professional skepticism and also to develop an empirical and testable hypothesis against the backdrop of the current literature. Second, in Study 2, an ordinary least squares regression based on data collected from 233 real auditor-client dyads in Germany reveals that auditors' identification-based trust is positively associated with their clients' perception of the auditors' professional skepticism. The identified coexistence of trust and professional skepticism in auditor-client dyads implies that regulatory measures that impede the evolution of trust between auditors and their clients wil.
Bilingual Semantic Role Labeling Inference via Dual Decomposition

This article focuses on bilingual Semantic Role Labeling (SRL); its goal is to annotate semantic roles on both sides of the parallel bilingual texts (bi-texts). Since rich bilingual information is encoded, bilingual SRL has been applied in many natural-language processing (NLP) tasks such as machine translation (MT), cross-lingual information retrieval (IR), and the like. A feasible way of performing bilingual SRL is using monolingual SRL systems to perform SRL on each side of bi-texts separately. However, it is difficult to obtain consistent SRL results on both sides of bi-texts in this way. Some works have tried to jointly infer bilingual SRL because there are many complementary language cues on both sides of bi-texts and they reported better performance than monolingual systems. However, there are two limits in the existing methods. First, the existing methods often require high inference costs due to the complex objective function. Second, the existing methods fully adopt the candidates generated by monolingual SRL systems, but many candidates are discarded in the argument pruning or identification stage of monolingual systems. In this article, we propose two strategies to overcome these limits. We utilize a simple but efficient technique: Dual Decomposition to search for consistent results for both sides of bi-texts. On the other hand, we propose a method called Bi-Directional Projection (BDP) to recover arguments discarded in monolingual SRL systems. We evaluate our method on a standard parallel benchmark: the OntoNotes dataset. The experimental results show that our method yields significant improvements over the state-of-the-art monolingual systems. In addition, our approach is also better and faster than existing methods due to BDP and Dual Decomposition.
Integrative computational analysis of transcriptional and epigenetic alterations implicates DTX1 as a putative tumor suppressor gene in HNSCC

Over a half million new cases of Head and Neck Squamous Cell Carcinoma (HNSCC) are diagnosed annually worldwide, however, 5 year overall survival is only 50% for HNSCC patients. Recently, high throughput technologies have accelerated the genome-wide characterization of HNSCC. However, comprehensive pipelines with statistical algorithms that account for HNSCC biology and perform independent confirmatory and functional validation of candidates are needed to identify the most biologically relevant genes. We applied outlier statistics to high throughput gene expression data, and identified 76 top-scoring candidates with significant differential expression in tumors compared to normal tissues. We identified 15 epigenetically regulated candidates by focusing on a subset of the genes with a negative correlation between gene expression and promoter methylation. Differential expression and methylation of 3 selected candidates (BANK1, BIN2, and DTX1) were confirmed in an independent HNSCC cohorts from Johns Hopkins and TCGA (The Cancer Genome Atlas). We further performed functional evaluation of NOTCH regulator, DTX1, which was downregulated by promoter hypermethylation in tumors, and demonstrated that decreased expression of DTX1 in HNSCC tumors maybe associated with NOTCH pathway activation and increased migration potential.
Declarative Data Generation with ProbLog

In this paper we describe a novel declarative approach to data generation based on probabilistic logic programming. We show that many data generation tasks can be described as a probabilistic logic program. To this end, we extend the ProbLog language with continuous distributions and we develop a simple sampling algorithm for this language. We demonstrate that many data generation tasks can be described as a model in this language and we provide examples of generators for attribute-value data, sequences, graphs and logical interpretations and we show how to model common extensions such as noise, missing values and concept drift.
Update on Retinal Prosthetic Research: The Boston Retinal Implant Project

The field of retinal prosthetic research, now more than 20 years old, has produced many high-quality technical options that have the potential to restore vision to patients with acquired disease of the outer retina. Five companies have performed Phase I clinical trials demonstrating that blind patients can reliably report basic elements of visual percepts induced by electrical stimulation. However, at present patients and observers generally do not consider the results to be useful enough in the performance of tasks of daily living to justify the risks of surgery and chronic implantation or the costs. Having developed a wireless device implanted in the subretinal space, the Boston Retinal Implant Project has focused its efforts on developing scalable technologies to create a hermetic device that can deliver individually controlled pulses of electrical stimulation to each of hundreds of electrodes. An advanced device with such attributes will be needed to justify the risks of implantation. An assessment of long-term biocompatibility for all devices remains to be done.
Visualizing Flat Spacetime: Viewing Optical versus Special Relativistic Effects

A visual representation of Minkowski spacetime appropriate for a student with a background in geometry and algebra is presented. Minkowski spacetime can be modeled with a Euclidean four-space to yield accurate visualizations as predicted by special relativity. The contributions of relativistic aberration as compared to classical prerelativistic aberration to the geometry are discussed in the context of its visual representation.
On the design of spectrally overlaid multiple-symbol-rate multicarrier CDMA systems supporting multirate services

Two types of spectrally overlaid multiple-symbol-rate (MSR) asynchronous multicarrier code division multiple access (MC-CDMA) systems are proposed. One type of systems has constant spreading gain (CSG) and the other has variable spreading gain (VSG) for different services; both systems have different symbol rates at each subcarrier for different services. Two possible configurations of CSG systems are also proposed. An adaptive power control is proposed to maintain the link quality and improve the system capacity. The multiple access interference, and hence system capacity, for each type of MSR MC-CDMA system is investigated. From the numerical results obtained, it can be concluded that the MSR MC-CDMA systems with VSG and with CSG configuration 2 can both obtain much steadier performance and system capacity than the system with CSG configuration 1.

Angiotensin-(1-7) intracerebroventricular administration generates nociceptive effects in hot-plate task and decreased oxidative stress in the temporal lobe

Lately, there is increased evidence that besides the very well known angiotensin (Ang) II, other renin-angiotensin system (RAS) peptides, including Ang III, Ang IV or Ang-(1–7), could mediate important effects at the central level. Thus, very few aspects are known about the central actions of Ang-(1-7), while the effects of its administration alone on nociception were very rarely tested to date, according to the best of our knowledge. Thus, we were interested in studying the effects of Ang-(1-7) intracerebroventricular administration on nociceptive sensibility, as expressed by the main behavioral parameters in the hot-plate task, a fundamental behavioral tool for the study of pain in rodents, as well as the importance of Ang-(1-7) in the oxidative stress status from the temporal lobe, which is considered one of the most vulnerable brain regions to the oxidative status modifications. Thus, we report here for the first time upon our knowledge a possible nociceptive effect of Ang-(1-7) intracerebroventricular administration, as demonstrated by increased latency-time in the hot-plate task. Moreover, it seems that oxidative stress could be implicated in these aspects, since we found a significant correlation between the latency-time in the hot-plate and the levels of most of the oxidative stress markers from the temporal lobe (such as the glutathione peroxidase enzymatic specific activity or the levels of the main peroxidation marker malondialdehyde). Thus, our results could suggest new perspectives and studies regarding the possible usage of brain RAS in pain management. Still, additional studies are required in order to better understand the effects of Ang-(1-7) administration on nociception and oxidative stress status and also on the possible correlation that might exist between these two aspects.
Research on an Ant Colony ISODATA Algorithm for Clustering Analysis in Real Time Computer Simulation

This paper intends to propose an advanced clustering method, ant colony ISODATA algorithm (ACIA) in real time computer simulation. Ant colony algorithm is used as the method of cursory clustering based on ants piling up their corpses and classifying their young ones. ISODATA algorithm is applied to meticulous clustering. This algorithm has been implemented and tested on several simulated data sets. At the same time, the performance efficiency of ACIA is analyzed based on four parameters :intracluster dissimilarity degree, intercluster dissimilarity degree, misclassification rate and CPU performance time. The computational results show that it is better than three other algorithms: ant colony K-means algorithm (ACKA), ant colony genetic algorithm (ACGA) and genetic K-means algorithm (GKA).
Motion Analysis for Short and Long Jump

Motion analysis is very essential in sport activities to enhance the performance of an athlete and to ensure the correctness of regimes. Expensive methods of motion analysis involving the use of sophisticated technology has led to limited application of motion analysis in sports. Towards this, in this paper we have integrated a lowcost method for motion analysis using three axis accelerometer, three axis magnetometer and microcontroller which are very accurate and easy to use. Seventeen male subjects performed two experiments, standing short jumps and long jumps over a wide range of take-off angles. During take-off and landing the acceleration and angles at different joints of the body are recorded using accelerometers and magnetometers, and the data is captured using Lab VIEW software. Optimum take-off angle in these jumps are calculated using the recorded data, to identify the optimum projection angle that maximizes the distance achieved in a jump. The results obtained for optimum take off angle in short jump and long jump is in agreement with those obtained using other methodologies and theoretical calculations assuming jump to be a projectile motion. The impact force (acceleration) is also analysed and is found to progressively decrease from foot to neck.
