Superconformal operators in N=4 super-Yang-Mills theory

We construct, in the framework of the N=4 SYM theory, a supermultiplet of twist-two conformal operators and study their renormalization properties. The components of the supermultiplet have the same anomalous dimension and enter as building blocks into multi-particle quasipartonic operators. The latter are determined by the condition that their twist equals the number of elementary constituent fields from which they are built. A unique feature of the N=4 SYM is that all quasipartonic operators with different SU(4) quantum numbers fall into a single supermultiplet. Among them there is a subsector of the operators of maximal helicity, which has been known to be integrable in the multi-color limit in QCD, independent of the presence of supersymmetry. In the N=4 SYM theory, this symmetry is extended to the whole supermultiplet of quasipartonic operators and the one-loop dilatation operator coincides with a Hamiltonian of integrable SL(2|4) Heisenberg spin chain.
Psychometric Properties of the Modified Posttraumatic Stress Disorder Symptom Scale among Women with Posttraumatic Stress Disorder and Substance Use Disorders Receiving Outpatient Group Treatments.

OBJECTIVE The use of psychometrically sound measures to assess and monitor PTSD treatment response over time is critical for better understanding the relationship between PTSD symptoms and Substance Use Disorder (SUD) symptoms throughout treatment. We examined the psychometric properties of the Modified Posttraumatic Stress Disorder (PTSD) Symptom Scale, Self-Report (MPSS-SR). METHODS Three hundred fifty three women diagnosed with co-occurring PTSD (full or sub-threshold) and SUD who participated in a multisite treatment trial completed the MPSS-SR at pre-treatment, weekly during treatment, and posttreatment. Reliability and validity analyses were applied to the data. RESULTS Internal consistency was excellent throughout the course of the trial demonstrating the MPSS-SR's high reliability. Strong correlations between MPSS-SR scores and the Brief Symptom Inventory and the Clinician Administered PTSD Scale (CAPS) severity scores demonstrated the MPSS-SR's convergent and concurrent validity. We conducted a classification analysis at posttreatment and compared the MPSS-SR at various cutoff scores with the CAPS diagnosis. A cutoff score of 29 on the MPSS-SR yielded a sensitivity rate of 89%, a specificity rate of 77%, and an overall classification rate of 80%, indicating the measure's robust ability to accurately identify individuals with PTSD in our sample at posttreatment. CONCLUSIONS Findings support the use of the MPSS-SR as a reliable and valid tool to assess and monitor changes in PTSD symptoms over the course of treatment and as an alternative to structured clinical interviews to assess PTSD symptoms among populations with SUDs.
Altered Neocortical Rhythmic Activity States in Fmr1 KO Mice Are Due to Enhanced mGluR5 Signaling and Involve Changes in Excitatory Circuitry

Despite the pronounced neurological deficits associated with mental retardation and autism, the degree to which neocortical circuit function is altered remains unknown. Here, we study changes in neocortical network function in the form of persistent activity states in the mouse model of fragile X syndrome—the Fmr1 knock-out (KO). Persistent activity states, or UP states, in the neocortex underlie the slow oscillation which occurs predominantly during slow-wave sleep, but may also play a role during awake states. We show that spontaneously occurring UP states in the primary somatosensory cortex are 38–67% longer in Fmr1 KO slices. In vivo, UP states reoccur with a clear rhythmic component consistent with that of the slow oscillation and are similarly longer in the Fmr1 KO. Changes in neocortical excitatory circuitry likely play the major role in this alteration as supported by three findings: (1) longer UP states occur in slices of isolated neocortex, (2) pharmacologically isolated excitatory circuits in Fmr1 KO neocortical slices display prolonged bursting states, and (3) selective deletion of Fmr1 in cortical excitatory neurons is sufficient to cause prolonged UP states whereas deletion in inhibitory neurons has no effect. Excess signaling mediated by the group 1 glutamate metabotropic receptor, mGluR5, contributes to the longer UP states. Genetic reduction or pharmacological blockade of mGluR5 rescues the prolonged UP state phenotype. Our results reveal an alteration in network function in a mouse model of intellectual disability and autism which may impact both slow-wave sleep and information processing during waking states.
Use of Four Dengue Virus Antigens for Determination of Dengue Immune Status by Enzyme-Linked Immunosorbent Assay of Immunoglobulin G Avidity

ABSTRACT We used an enzyme-linked immunosorbent assay (ELISA) of immunoglobulin G avidity to determine the dengue immune status of 105 pairs of serum samples from patients infected with dengue virus. This study shows that a simple avidity test, for which only one acute-phase serum sample is required, is potentially more useful than the hemagglutination inhibition test for the discrimination of primary from secondary dengue virus infection, whatever the type of dengue antigen used.
A Bias Toward Short-Term Thinking in Threat-Related Negative Emotional States

Some decisions must be made repeatedly and have consequences that change depending on how often each alternative is chosen. Such temporally extended decisions are pervasive and important, and often involve short-term/long-term tradeoffs. Can unrelated emotion and stress influence such decisions? In negative emotional states involving threats, people should favor what is better at the time regardless of possible long-term consequences. Supporting this hypothesis, in Experiment 1, college students randomly assigned to see aversive images repeatedly made choices that had better short-term but poorer long-term effects, and so earned less money than students shown neutral images, effect size r = . 71. In Experiment 2, students reporting stress about impending exams showed a similar bias, r=. 53.Thehypothesis and results are relevant to decision making, delay of gratification, distributed choice, and self-control.
Measuring sympathy toward handicapped children with the “lost-letter” technique1

Abstract Three hundred stamped and addressed letters were “lost” in public places. The manipulation consisted of varying the addresses on the envelopes, there being five experimental and one control condition, each with an N of 50. In the experimental conditions, the letters were addressed to groups concerned with the welfare of handicapped children, whereas the control was simply the Children's Aid Group. The response rate in four of the five experimental conditions was greater than in the control condition, thereby providing evidence for the predictive validity of the “lost-letter” technique.
Guanabara Bay , RJ , Brazil

The distribution of selected aromatic compounds and microbiology were assessed in superficial sediments from Suruí Mangrove, Guanabara Bay. Samples were collected at 23 stations, and particle size, organic matter, aromatic compounds, microbiology activity, biopolymers, and topography were determined. The concentration of aromatic compounds was distributed in patches over the entire mangrove, and their highest total concentration was determinated in the mangrove’s central area. Particle size differed from most mangroves in that Suruí Mangrove has chernies on the edges and in front of the mangrove, and sand across the whole surface, which hampers the relationship between particle size and hydrocarbons. An average ' 10% p/p of organic matter was obtained, and biopolymers presented high concentrations, especially in the central and back areas of the mangrove. The biopolymers were distributed in high concentrations. The presence of fine sediments is an important factor in hydrocarbon accumulation. With high concentration of organic matter and biopolymers, and the topography with chernies and roots protecting the mangrove, calmer areas are created with the deposition of material transported by wave action. Compared to global distributions, concentrations of aromatic compounds in Suruí Mangrove may be classified from moderate to high, showing that the studied area is highly impacted.
Overlapping upper and lower gastrointestinal symptoms in irritable bowel syndrome patients with constipation or diarrhea

OBJECTIVES:Distinguishing between irritable bowel syndrome (IBS) and functional dyspepsia can be challenging because of the variations in symptom patterns, which commonly overlap. However, the overlap is poorly quantified, and it is equally uncertain whether symptom patterns differ in subgroups of IBS arbitrarily defined by primary bowel patterns of constipation (IBS-C) and diarrhea (IBS-D). We aimed to determine and to compare the distribution of GI symptoms, both, upper and lower, among IBS-C and IBS-D patients.METHODS:A total of 121 consecutive patients presenting with a diagnosis of IBS were grouped according to primary bowel symptoms as IBS-C (58 women and 18 men, mean age 47 ± 17 yr) or IBS-D (26 women and 19 men, mean age 47 ± 15 yr). The Hopkins Bowel Symptom Questionnaire, which includes a brief Quality of Life assessment, and the Hopkins Symptom Checklist 90-Revised were completed by all patients at intake.RESULTS:IBS-C patients reported significantly more overall GI symptoms when compared to patients with IBS-D (6.67 vs 4.62, respectively, p < 0.001). Abdominal pain patterns differed in patients with IBS-C versus IBS-D (lower abdominal pain: 40.8%vs 24.4%p = 0.05 and upper abdominal pain: 36.8%vs 24.4%, respectively). Bloating was substantially more common in IBS-C patients (75%) than in IBS-D (40.9%). There were no significant differences in personality subscales by IBS subgroup; however, somatization was positively associated with multiple symptom reports and was negatively correlated with quality of life.CONCLUSIONS:Upper GI symptoms consistent with functional dyspepsia were more frequent in IBS-C. Although there was considerable overlap of upper and lower GI symptoms in patients with IBS-C and IBS-D, the former had more frequent lower abdominal pain and bloating.
Emotional Problems of Relatives of Dysphasic Patients

Each year hundreds of people in Adelaide suffer a stroke and, of these, a good many are admitted to the Rehabilitation Unit at Daws Road Repatriation Hospital with dysphasic symptoms. Over 18 months ago, as part of the Unit's concern for the family of the patient, a “Relatives Group” was commenced and has been held every two weeks since. Through experience in the group, it became clear that the relatives developed their own emotional problems which, in most cases, required “treatment” by the local doctor or the group itself. The psychologist, who attended every group, became involved in treating the relatives and referrals were made to Psychiatrists from time to time. The sorts of emotional problems encountered are thought to be the direct result of chronic stress on personalities, some of whom are vulnerable, who are undergoing a massive lifestyle change, in coping with the dysphasic stroke patient. In this paper is presented an outline of the group, its workings, and the results of our first questionnai.

Integrating Word Embedding Offsets into the Espresso System for Part-Whole Relation Extraction

Part-whole relation, or meronymy plays an important role in many domains. Among approaches to addressing the part-whole relation extraction task, the Espresso bootstrapping algorithm has proved to be effective by significantly improving recall while keeping high precision. In this paper, we first investigate the effect of using fine-grained subtypes and careful seed selection step on the performance of extracting part-whole relation. Our multitask learning and careful seed selection were major factors for achieving higher precision. Then, we improve the Espresso bootstrapping algorithm for part-whole relation extraction task by integrating word embedding approach into its iterations. The key idea of our approach is utilizing an additional ranker component, namely Similarity Ranker in the Instances Extraction phase of the Espresso system. This ranker component uses embedding offset information between instance pairs of part-whole relation. The experiments show that our proposed system achieved a precision of 84.9% for harvesting instances of the partwhole relation, and outperformed the original Espresso system.
Teaching Patients With Low Literacy Skills

It is estimated that 1 out of 5 American adults lacks the literacy skills needed to function effectively in todays society and as patients they present a challenge to health instruction. This book provides teaching strategies to aid in making self-help and self-management a reality for the patient with low literacy skills. The magnitude of the problem is explored and myths about illiteracy are exemplified. Two chapters deal with comprehension of written materials from theory to practical proven testing techniques including the cloze technique and the word-recognition test. Another chapter offers 2 formulas for testing the readability of written materials: the SMOG formula and the Fry index. Once a problem is identified a 4-step teaching strategy gives tips on teaching the low-literacy patient. For those pamphlets and booklets commonly given to patients suggestions for writing and rewriting to simplify the text are given along with examples of comprehension level. The use of audiotapes for teaching is explored in depth for those who learn better by listening. A chapter on the use of visuals stresses simplification to reduce the amount of text reading to emphasize instruction and to motivate and appropriate examples are given. Where written material audiotapes and visuals are drafted and produced according to the guidelines in the book the last chapter is devoted to pretesting to determine whether intended concepts are coming through. It defines the components of pretesting describes procedures discusses possible stages for production and provides examples of results. Although the book is aimed at providing teaching methods for the low-literate patient the suggestions also apply to the learning disabled.
Intrusion detection system using fuzzy genetic algorithm

Computer security has become an important part of the day today's life. Not only single computer systems but an extensive network of the computer system also requires security. In achieving the safety of the systems, an Intrusion Detection System (IDS) plays a significant role. IDS is a software that monitors the computer network and detects the suspicious activities that occur in the systems or network. The process of intrusion detection includes detecting intrusion. Intrusion is a suspicious activity attempted by the attacker. This paper presents a fuzzy-genetic approach to detecting network intrusion. Paper presents the results of the proposed system in terms of accuracy, execution time, and memory allocation. To implement and measure the performance of the system the KDD99 benchmark dataset is used. The KDD99 dataset is a benchmark dataset that researchers use in various network security researches. Genetic algorithm includes a development and collection that uses a chromosome like data structure and develop the chromosomes using selection, crossover and mutation operators. Fuzzy rule sorts network attack data.
Karl Haushofer and geopolitics — the history of a German mythos

This essay attempts to reassess the writings of Karl Haushofer, a German professor of geopolitics during the period of the Third Reich. However, this examination is not to be another historical reflection. Instead it approaches the question what different kinds of historical reflections on Karl Haushofer as a person and his geopolitics were made in Germany and how they influenced the further geopolitical research. The different interpretations of Haushofer are examined in the form of a discourse analytic study. It shows that the different judgments concerning his work are open to diverse political interpretations.
Fixing bugs in your sleep: how genetic improvement became an overnight success

We present a bespoke live system in commercial use with self-improving capability. During daytime business hours it provides an overview and control for many specialists to simultaneously schedule and observe the rehabilitation process for multiple clients. However in the evening, after the last user logs out, it starts a self-analysis based on the day's recorded interactions. It generates test data from the recorded interactions for Genetic Improvement to fix any recorded bugs that have raised exceptions. The system has already been under test for over 6 months and has in that time identified, located, and fixed 22 bugs. No other bugs have been identified by other methods during that time. It demonstrates the effectiveness of simple test data generation and the ability of GI for improving live code.
Efficient Projection for Compressed Sensing

Compressed sensing (CS), a joint compression and sensing process, is a emerging field of activity in which the signal is sampled and simultaneously compressed at a greatly reduced rate. In CS, the projection matrix is chosen at random which would lead to inefficient performance of CS. Recently, an optimized projection (OP) was chosen such that it leads to better coherence of the effective dictionary, leading substantially better CS reconstruction performance. This is the only recent work related to the optimization of projection matrix, but the major drawback of this approach is that its algorithm is an iterative and high complexity one. It is considered that an efficient and lightweight algorithm for designing projection matrix would usefully supplement and enhance the performance of CS. In this paper, we propose an algorithm to obtain such an projection matrix called efficient projection (EP) which is designed in such a way that the new projected dictionary will have the structure as much similar as the original dictionary. For this purpose, we use multidimensional scaling (MDS) technique which helps to find a low-dimensional new projected dictionary such that the pairwise distances between new atoms in this new projected dictionary match as well as possible the original atoms in original dictionary. This leads to a solution for EP which is very simple and can be obtained by doing singular value decomposition of original dictionary. The experiments show the novelty of our approach when it can gain a comparative performance with a very low complexity compared to that of OP.
Predictors of ischemic stroke after hip operation: a population-based study.

BACKGROUND Hip operation (total hip arthroplasty [THA] or fracture repair) is the most common noncardiac surgical procedure performed in patients age 65 years and older. OBJECTIVE To determine the predictors of ischemic stroke in patients who have undergone hip operation. DESIGN Population-based historical cohort study, in which postoperative ischemic strokes were identified from medical record review for stroke diagnostic codes and brain imaging results and were confirmed by physician review. SETTING Tertiary care center in Olmsted County, Minnesota. PATIENTS Residents of Olmsted County who underwent hip surgical procedure. MEASUREMENTS Incidence of ischemic stroke within 1 year of hip operation. RESULTS In total, 1606 patients underwent 1886 hip procedures from 1988 through 2002 and were observed for ischemic stroke for 1 year after their procedure. Sixty-seven ischemic strokes were identified. The rate of stroke at 1 year after hip operation was 3.9%. In univariate analysis, history of atrial fibrillation (hazard ratio [HR], 2.16; P = 0.005), hip fracture repair vs. total hip arthroplasty (HR, 3.80; P < 0.001), age 75 years or older (HR, 2.20; P = 0.02), aspirin use (HR, 1.8; P = 0.01), and history of previous stroke (HR, 4.18; P < 0.001) were significantly associated with increased risk of stroke. In multivariable analysis, history of stroke (HR, 3.27; P < 0.001) and hip fracture repair (HR, 2.74; P = 0.004) were strong predictors of postoperative stroke. CONCLUSIONS This population-based historical cohort of patients with hip operation had a 3.9% cumulative probability of ischemic stroke over the first postoperative year. Hip fracture repair and history of stroke were the strongest predictors of this complication.
Optimization of a fuzzy decision trees forest with artificial ant based clustering

In the recent years, forests of decision trees have seen an increasing interest from the Machine Learning community since they allow to aggregate the decisions from a set of decision trees into one robust answer. However, this approach suffers from two well-known limits: first, their performances depend on the number of trees and thus finding the right size and how to aggregate decisions could be very difficult and second, large forests loose the interpretability capacity of a single decision tree. In this paper, we propose a new approach in which decisions trees from a forest are clustered to simplify the overall decision process while maintaining a large amount of decision trees and to facilitate the interpretation of the results. The preliminary results that are presented in this paper show the effectiveness of our approach.
The effects of political participation on political efficacy: A simultaneous equations model

The absence of studies investigating the influence of political participation on individuals’ perceptions of political efficacy constitutes a significant gap in our knowledge of political behaviour. While many researchers have investigated the influence of efficacy on political participation, and there has been some endeavour to examine the reciprocity of the relationship between the variables, none has estimated a comprehensive model of the impact of individuals’ participation is different kinds of political activity on different aspects of their perceptions of political efficacy. We redress these particular deficiencies in our knowledge of political behaviour, investigating the influence of participation in three different modes of activity—partisan activism, community activism and political extremism—on individuals’ perceptions of internal and external efficacy; that is, their perceptions of political self‐competence and system responsiveness. Our findings confirm that the relationships between differe.
