Spectrum Sharing between DSRC and WiFi: A Repeated Game Approach

We model the coexistence of Dedicated Short Range Communications (DSRC) and WiFi networks, when they access a shared wireless medium, as a repeated game. Both the networks use a similar CSMA/CA like medium access mechanism. However, while a DSRC network cares for the freshness of status updates and desires to minimize the age of received updates, a WiFi network would like to maximize throughput. We define the stage game, which is parameterized by the average age of the DSRC network at the beginning of the stage, and derive its mixed strategy Nash equilibrium. We study the evolution of the equilibrium strategies over time and the resulting average discounted payoffs of the networks. It turns out that DSRC’s requirement of timely updates works in favour of WiFi, making spectrum sharing with DSRC favorable for a WiFi network in comparison to sharing with another WiFi network. Specifically, as we show, the equilibrium strategy has the DSRC network, given its requirement of timeliness, occasionally refrain from transmitting during a stage. Such stages allow the WiFi network competition free access to the medium.
Signed Network Structural Analysis and Applications with a Focus on Balance Theory

We analyse signed networks from the perspective of balance theory which predicts structural balance as a global structure for signed social networks that represent groups of friends and enemies. The scarcity of balanced networks encouraged us to define the notion of partial balance in order to quantify the extent to which a network is balanced. We evaluate several numerical measures of partial balance and recommend using the frustration index, a measure that satisfies key axiomatic properties and allows us to analyse graphs based on their levels of partial balance. The exact algorithms used in the literature to compute the frustration index, also called the line index of balance, are not scalable and cannot process graphs with a few hundred edges. We formulate computing the frustration index as a graph optimisation problem to find the minimum number of edges whose removal results in a balanced network given binary decision variables associated with graph nodes and edges. We use our first optimisation model to analyse graphs with up to 3000 edges. Reformulating the optimisation problem, we develop three more efficient binary linear programming models. Equipping the models with valid inequalities and prioritised branching as speed-up techniques allows us to process graphs with 15000 edges on inexpensive hardware. Besides making exact computations possible for large graphs, we show that our models outperform heuristics and approximation algorithms suggested in the literature by orders of magnitude. We extend the concepts of balance and frustration in signed networks to applications beyond the classic friend-enemy interpretation of balance theory in social context. Using a high-performance computer, we analyse graphs with up to 100000 edges to investigate a range of applications from biology and chemistry to finance, international relations, and physics.
Dual Graph-Laplacian PCA: A Closed-Form Solution for Bi-Clustering to Find “Checkerboard” Structures on Gene Expression Data

In the context of cancer, internal “checkerboard” structures are normally found in the matrices of gene expression data, which correspond to genes that are significantly up- or down-regulated in patients with specific types of tumors. In this paper, we propose a novel method, called dual graph-regularization principal component analysis (DGPCA). The main innovation of this method is that it simultaneously considers the internal geometric structures of the condition manifold and the gene manifold. Specifically, we obtain principal components (PCs) to represent the data and approximate the cluster membership indicators through Laplacian embedding. This new method is endowed with internal geometric structures, such as the condition manifold and gene manifold, which are both suitable for bi-clustering. A closed-form solution is provided for DGPCA. We apply this new method to simultaneously cluster genes and conditions (e.g., different samples) with the aim of finding internal “checkerboard” structures on gene expression data, if they exist. Then, we use this new method to identify regulatory genes under the particular conditions and to compare the results with those of other state-of-the-art PCA-based methods. Promising results on gene expression data have been verified by extensive experiments.
MIMIC-CXR-JPG, a large publicly available database of labeled chest radiographs

Chest radiography is an extremely powerful imaging modality, allowing for a detailed inspection of a patient's thorax, but requiring specialized training for proper interpretation. With the advent of high performance general purpose computer vision algorithms, the accurate automated analysis of chest radiographs is becoming increasingly of interest to researchers. However, a key challenge in the development of these techniques is the lack of sufficient data. Here we describe MIMIC-CXR-JPG v2.0. 0, a large dataset of 377,110 chest x-rays associated with 227,827 imaging studies sourced from the Beth Israel Deaconess Medical Center between 2011 - 2016. Images are provided with 14 labels derived from two natural language processing tools applied to the corresponding free-text radiology reports. MIMIC-CXR-JPG is derived entirely from the MIMIC-CXR database, and aims to provide a convenient processed version of MIMIC-CXR, as well as to provide a standard reference for data splits and image labels. All images have been de-identified to protect patient privacy. The dataset is made freely available to facilitate and encourage a wide range of research in medical computer vision.
Foothill: A Quasiconvex Regularization Function

Deep neural networks (DNNs) have demonstrated success for many supervised learning tasks, ranging from voice recognition, object detection, to image classification. However, their increasing complexity yields poor generalization error. Adding noise to the input data or using a concrete regularization function helps to improve generalization. Here we introduce foothill function, an infinitely differentiable quasiconvex function. This regularizer is flexible enough to deform towards $L_1$ and $L_2$ penalties. Foothill can be used as a loss, as a regularizer, or as a binary quantizer.
Debugging Frame Semantic Role Labeling

We propose a quantitative and qualitative analysis of the performances of statistical models for frame semantic structure extraction. We report on a replication study on FrameNet 1.7 data and show that preprocessing toolkits play a major role in argument identification performances, observing gains similar in their order of magnitude to those reported by recent models for frame semantic parsing. We report on the robustness of a recent statistical classifier for frame semantic parsing to lexical configurations of predicate-argument structures, relying on an artificially augmented dataset generated using a rule-based algorithm combining valence pattern matching and lexical substitution. We prove that syntactic pre-processing plays a major role in the performances of statistical classifiers to argument identification, and discuss the core reasons of syntactic mismatch between dependency parsers output and FrameNet syntactic formalism. Finally, we suggest new leads for improving statistical models for frame semantic parsing, including joint syntax-semantic parsing relying on FrameNet syntactic formalism, latent classes inference via split-and-merge algorithms and neural network architectures relying on rich input representations of words.
Numerical Simulation of Melting with Natural Convection Based on Lattice Boltzmann Method and Performed with CUDA Enabled GPU

A new solver is developed to numerically simulate the melting phase change with natural convection. This solver was implemented on a single Nvidia GPU based on the CUDA technology in order to simulate the melting phase change in a 2D rectangular enclosure. The Rayleigh number is of the order of magnitude of 10 8 and Prandlt is 50. The hybrid thermal lattice Boltzmann method (HTLBM) is employed to simulate the natural convection in the liquid phase, and the enthalpy formulation is used to simulate the phase change aspect. The model is validated by experimental data and published analytic results. The simulation results manifest a strong convection in the melted phase and a different flow pattern from the reference results with low Rayleigh number. In addition, the computational performance is estimated for single precision arithmetic, and this solver yields 703.31MLUPS and 61.89GB/s device to device data throughput on a Nvidia Tesla C2050 GPU.
Alcohol Use Disorders in Female Survivors of Childhood Sexual Abuse

Abstract This article reviews some of the recent research concerning factors that contribute to the development of alcohol use disorders in females who were sexually abused as children. Issues pertaining to a possible history of childhood sexual abuse are often overlooked in treating adult females who have alcohol use disorders. Implications for assessment and treatment are discussed. It is recommended that mental health and substance abuse counselors become aware of strategies to detect the interactive effects of these two disorders so that a more integrated and effective treatment approach can be implemented.
Use of Early Goal-Directed Therapy in the Emergency Department before and after the Sepsis Trilogy

The management of sepsis evolved recently with the publication of three large trials (referred to as the sepsis trilogy) investigating the efficacy of early goal-directed therapy (EGDT). Our goal was to determine if the publication of these trials has influenced the use of EGDT when caring for patients with severe sepsis and septic shock in the emergency department (ED). In February 2014, we surveyed a sample of board-certified emergency medicine physicians regarding their use of EGDT in the ED. A follow-up survey was sent after the publication of the sepsis trilogy. Data was analyzed using 95% confidence intervals to determine if there was a change in the use of EGDT following the publication of the above trials. Subgroup analyses were also performed with regard to academic affiliation and emergency department volume. Surveys were sent to 308 and 350 physicians in the pre-and post-publication periods, respectively. Overall, ED use of EGDT did not change with publication of the sepsis trilogy, 48.7% (CI 39.3% - 58.2%) before and 50.5% (CI 40.6% - 60.3%) after. Subgroup analysis revealed that academic-affiliated EDs significantly decreased EGDT use following the sepsis trilogy while nonacademic departments significantly increased EGDT use. Use of EGDT was significantly greater in community departments versus academic departments following the publication of the sepsis trilogy. There was no change overall in the use of EGDT protocols when caring for patients with severe sepsis and septic shock, but subgroup analyses revealed that academic departments decreased their use of EGDT while community departments increased use of EGDT. This may be due to varying rates of uptake of the medical literature between academic and community healthcare systems.

Prevalence of Iron Deficiency Anemia among Chronic Kidney Disease Patients in Kaveri Delta Region, Tamilnadu, India

Background: Iron deficiency anemia (IDA) is the most common type of anemia. But the incidence of iron deficiency anemia in chronic kidney disease (CKD) has not been well established in Kaveri Delta Region, Tamilnadu, India. Hence, the present study has been undertaken to evaluate the prevalence of iron deficiency anemia in chronic kidney disease patients of Kaveri Delta Region, Tamilnadu, India. Materials and Methods: The present study enrolled 221 chronic kidney disease patients from a private nephrology outpatient clinic, Tiruchirappalli. All biochemical tests were done including serum ferritin. Patients were categorized into two groups based on ferritin levels. Group 1 (N: 87) considered as case and the group 2 (N: 134) patients considered as control. These two groups were compared each other respective with gender and age groups with all parameters. Results: Out of these patients, 87 belonged to iron deficiency anemia patients. Group 1 patients (Total Number of Patients: 87 Male: 29 Female: 58) showing significantly lower serum ferritin levels (15.04±12.48) than group 2 patients (88.98±47.39) ( P <0.0001). Within group 1, females had lower ferritin levels (12.98±8.84) than males (17.11±10.78) in the age group of 31-40 years ( P <0.0001). Conclusion: The prevalence of iron deficiency anemia among chronic kidney disease in Kaveri Delta Region was found to be 39%.
PATIENTS’ PERCEPTION TOWARDS INFECTION TRANSMISSION IN DENTAL PRACTICES IN IASI, ROMANIA

Aim: To assess patients’ perception and attitudes concerning the risk of infection transmission in dental practices in Iasi, Romania. Material and methods: A questionnaire-based study was conducted amongst 280 patients aged between 21 and 62 in 32 private dental offices in Iasi, Romania. The 16 questions were related to patients’ attitude towards the risk of infection and their involvement in assessing the safety protocols. The data were analyzed by gender, age and education level using the SPSS 15.0 statistical package (p<0.05) and Chi square test. Results: Most patients (82.6%) manifest their trust in the medical staff to protect them against the spread of infection. 10,9% of the subjects avoid dental care as a result of the risk of getting infected. 46,5% of the patients are concerned about the safety measures used during their dental treatment. Women desire to involve themselves in assessing the implementation of infection control measures more than men (63.6%, 50.0%, respectively). HIV infection, viral hepatitis B and C and influenza are considered by the patients to be the most frequently transmitted during dental treatment. Older subjects (81.4%) and those with secondary educational level (67.3%) do not consider that their implication in infection control is necessary. The dental assistant is associated with infection transmission by 62.7% of patients. Conclusions: The assessment of patients’ specific requirements and needs is essential in order to increase the medical team knowledge and awareness regarding the level of patient safety.

A systematic approach to practice-based evidence in a psychological therapies service

This paper describes a systematic approach to generating practice-based evidence in a United Kingdom adult psychological therapies service. Routine clinical outcomes using standardized measures at referral, assessment, the beginning of therapy, discharge and 6-month follow-up are reported. The system is integrated into the clinical service in many ways including contributing to risk assessment and feeding back clinical outcome data to the therapists. A number of issues related to such an approach are discussed in the light of the clinical governance and clinical effectiveness agendas in the UK NHS. These include practical constraints, the costs, getting staff on board, attrition from such services and service user involvement. Such an approach provides a framework for routine, systematic and integrated service evaluation that can be fed back to therapists. It contributes to the evidence for the effectiveness of psychological therapies in routine clinical settings and also provides opportunities to link evidence with practice in more creative ways to enhance therapists' reflection on their practice.
