The Mobile Network is highly constraint requirement to improve the quality of service in secure way, it uses different changes in MANET protocols, its parameters, routing algorithm etc. Nature inspired and the challenges with respect to routing protocols, security aspect in Mobile Ad hoc Network (MANET) s. The proposed work is to define a genetic based routing approach to optimize the routing in MANETs. The genetic approach will generate an optimized path on the basic of congestion over the network and to improve the Quality of Service (QoS) and propose reliability which makes use of solutions to security problems
Dissociation between recency and span: neuropsychological and experimental evidence.

This article reports dissociations between verbal span and the recency portion of the serial position curve in immediate free recall, in 2 neuropsychological case studies and in 3 experiments with normal participants. Patient A. N. presented with an impaired serial verbal span while showing an intact recency effect. The opposite pattern was observed in patient G. C. , who despite a poor recency showed normal span in verbal serial recall tasks. Experiments 1 and 2 showed a recency effect with visually and auditory presented lists and written recall was resistant to the effects of articulatory suppression and of irrelevant speech, but was disrupted by the suffix effect. Experiment 3 showed that in contrast with recency, memory span was affected by articulatory suppression and irrelevant speech during presentation but not by a suffix. These findings are not consistent with the idea that span and recency measure aspects of the same memory system. Moreover, in clinical practice, they should not be used as equivalent alternatives.
Antibiotic-refractory Lyme arthritis is associated with HLA-DR molecules that bind a Borrelia burgdorferi peptide

An association has previously been shown between antibiotic-refractory Lyme arthritis, the human histocompatibility leukocyte antigen (HLA)–DR4 molecule, and T cell recognition of an epitope of Borrelia burgdorferi outer-surface protein A (OspA163–175). We studied the frequencies of HLA-DRB1-DQA1-DQB1 haplotypes in 121 patients with antibiotic-refractory or antibiotic-responsive Lyme arthritis and correlated these frequencies with in vitro binding of the OspA163–175 peptide to 14 DRB molecules. Among the 121 patients, the frequencies of HLA-DRB1-DQA1-DQB1 haplotypes were similar to those in control subjects. However, when stratified by antibiotic response, the frequencies of DRB1 alleles in the 71 patients with antibiotic-refractory arthritis differed significantly from those in the 50 antibiotic-responsive patients (log likelihood test, P = 0.006; exact test, P = 0.008; effect size, Wn = 0.38). 7 of the 14 DRB molecules (DRB1*0401, 0101, 0404, 0405, DRB5*0101, DRB1*0402, and 0102) showed strong to weak binding of OspA163–175, whereas the other seven showed negligible or no binding of the peptide. Altogether, 79% of the antibiotic-refractory patients had at least one of the seven known OspA peptide–binding DR molecules compared with 46% of the antibiotic-responsive patients (odds ratio = 4.4; P < 0.001). We conclude that binding of a single spirochetal peptide to certain DRB molecules is a marker for antibiotic-refractory Lyme arthritis and might play a role in the pathogenesis of the disease.
Defect Inflow Prediction in Large Software Projects

Performance of software projects can be improved by providing predictions of various project characteristics. The predictions warn managers with information about potential problems and provide them with the possibility to prevent or avoid problems. Large software projects are characterized by a large number of factors that impact the project performance, which makes predicting project characteristics dicult. This paper presents methods for constructing prediction models of trends in defect inflow in large software projects based on a small number of variables. We refer to these models as short-term prediction models and long-term prediction models. The short-term prediction models are used to predict the number of defects discovered in the code up to three weeks in advance, while the long-term prediction models provide the possibility of predicting the defect inflow for the whole project. The initial evaluation of these methods in a large software project at Ericsson shows that the models are suciently accurate and easy to deploy.
Divorce and Health

In this article, we review what is known about the association between marital dissolution and health outcomes in adults. Two of the major empirical findings in the literature—that most people do well following marital separation and that this life event increases risk for poor outcomes—appear to be in contrast. We provide an individual differences framework for reconciling these competing perspectives and suggest that the bulk of the risk for poor outcomes following marital dissolution is carried by a minority of people. Research focusing on at-risk populations is beginning to shed light on the processes that explain why and how marital separation and divorce are associated with ill health. This article outlines a series of future directions that go beyond individual differences to study these mechanisms.
Numerical Relation Extraction with Minimal Supervision

We study a novel task of numerical relation extraction with the goal of extracting relations where one of the arguments is a number or a quantity ( e.g., atomic_number(Aluminium, 13), inflation_rate(India, 10.9%)). This task presents peculiar challenges not found in standard IE, such as the difficulty of matching numbers in distant supervision and the importance of units. We design two extraction systems that require minimal human supervision per relation: (1) NumberRule, a rule based extractor, and (2) NumberTron, a probabilistic graphical model. We find that both systems dramatically outperform MultiR, a state-of-the-art non-numerical IE model, obtaining up to 25 points F-score improvement.
OPN06-2: Performance of Scheduling Algorithms in Multi-Stage Optical Packet Switches with Sparse Wavelength Converters

This paper describes the scheduling algorithms to control the optical packet forwarding in a multi-stage switch based on the broadcast-and-select principle. The aim of control algorithms is to fully exploit switch resources while avoiding contention in the wavelength and space domains. A multi-stage switch based on the shared per node wavelength conversion scheme is considered in a synchronous context. An analytical model is provided to calculate the packet loss probability in relation to different reference traffic scenarios. Results show how the sharing of wavelength converters impacts on node performance depending on the scheduling algorithm applied, and provide a meaningful support for optical packet switch design.
Inpainting Large Missing Regions in Range Images

We propose a technique to in paint large missing regions in range images. Such a technique can be used to restore degraded/occluded range maps. It can also serve to reconstruct dense depth maps from sparse measurements which can speed up the acquisition. Our method uses the visual cue from segmentation of an intensity image registered to the range image. Our approach enforces that pixels in the same segment should have similar range. Our simple strategy involves plane-fitting and local medians over segments to compute local energies for labeling unknown pixels. Our results exhibit high quality in painting with very low errors.
O Antigen Protects Bordetella parapertussis from Complement

ABSTRACT Bordetella pertussis, a causative agent of whooping cough, expresses BrkA, which confers serum resistance, but the closely related human pathogen that also causes whooping cough, Bordetella parapertussis, does not. Interestingly, B. parapertussis, but not B. pertussis, produces an O antigen, a factor shown in other models to confer serum resistance. Using a murine model of infection, we determined that O antigen contributes to the ability of B. parapertussis to colonize the respiratory tract during the first week of infection, but not thereafter. Interestingly, an O antigen-deficient strain of B. parapertussis was not defective in colonizing mice lacking the complement cascade. O antigen prevented both complement component C3 deposition on the surface and complement-mediated killing of B. parapertussis. In addition, O antigen was required for B. parapertussis to systemically spread in complement-sufficient mice, but not complement-deficient mice. These data indicate that O antigen enables B. parapertussis to efficiently colonize the lower respiratory tract by protecting against complement-mediated control and clearance.
Calf Augmentation and Restoration

Background: Calf augmentation is indicated for cosmetic reasons or to reconstruct a shrunken lower leg that is the result of injury, illness, or congenital disability. Calf implants are made of solid semisoft silicone, which can be customized by carving, or of a thick shell of solid silicone containing cohesive silicone. Methods: During the years 1991 through 2004, 18 patients (13 women and five men) underwent 20 calf augmentations at the Lidingö Clinic in Stockholm. Indication for operation was aesthetic in 10 patients. Four patients were body-builders. Another four underwent unilateral crural restoration because of the deformity caused by an illness. Both cigar-shaped and anatomically formed silicone implants filled with cohesive gel were used. Several technical improvements were introduced; among them, a new instrument for insertion of the implants. The long-acting anesthetic ropivacaine was used to flush the dissected cavity and for intermittent regional analgesia during the first postoperative day. One or two implants were placed in the space between the investing crural fascia and gastrocnemius muscle, depending on the aesthetic demand. In five patients, an augmentation procedure was combined with circumferential liposuction of the lower legs. Results: All patients obtained good aesthetic improvement and were satisfied with the outcome. No serious complications were encountered in this series. Liposuction contributed to better cosmesis and symmetry in some aesthetic patients and was particularly important in the reconstructive cases. Ropivacaine flush almost eliminated the postoperative pain and discomfort. Several clinical examples of calf augmentation attributable for aesthetic and/or medical reasons are presented. Conclusion: Calf augmentation or reconstruction with silicone implants is a safe, efficient, and satisfying aesthetic procedure.
The composition of surface wax on trichomes of Arabidopsis thaliana differs from wax on other epidermal cells.

To protect plants against biotic and abiotic stress, the waxy cuticle must coat all epidermis cells. Here, two independent approaches addressed whether cell-type-specific differences exist between wax compositions on trichomes and other epidermal cells of Arabidopsis thaliana, possibly with different protection roles. First, the total waxes from a mutant lacking trichomes (gl1) were compared to waxes from wild type and a trichome-rich mutant (cpc tcl1 etc1 etc3). In the stem wax, compounds with aliphatic chains longer than 31 carbons (derived from C32 precursors) increased in relative abundance in cpc tcl1 etc1 etc3 over gl1. Similarly, the leaf wax from the trichome-rich mutant contained higher amounts of C32+ compounds as compared to gl1. Second, leaf trichomes were isolated, and their waxes were analyzed. The wax mixtures of the trichome-rich mutant and the wild type were similar, comprising alkanes and alkenes as well as branched and unbranched primary alcohols. The direct analyses of trichome waxes confirmed that they contained relatively high concentrations of C32+ compounds, compared with the pavement cell wax inferred from analysis of gl1 leaves. Finally, the cell-type-specific wax compositions were put into perspective with expression patterns of wax biosynthesis genes in trichomes and pavement cells. Analyses of published transcriptome data (Marks et al., ) revealed that core enzymes involved in elongation of wax precursors to various carbon chain lengths are expressed differentially between epidermis cell types. By combining the chemical and gene expression data, we identified promising gene candidates involved in the formation of C32+ aliphatic chains.
Integrated Magnesium Technology

Recent developments in the field of green sand moulding, together with low cost of moulding materials (green sand), high degree of recyclability of moulding materials and high flexibility of green sand moulding process were the key factors, fostering Foundry Institute of Technical University of Freiberg to start an extensive study on sand casting of magnesium alloys. This study focused on two aspects: technology of green sand moulding for magnesium and mechanical properties of magnesium sand cast parts. Since aluminium-containing alloys is the most widely used group of magnesium casting alloys, we concentrated on classic alloy AZ91HP. Key results of this study are presented in this paper.
INTELLIGENT AGENTS IN DESIGN

In this paper we argue that learning or adaptation ability should be included in the basic set of features characterizing an intelligent agent in design. We propose a collection of attributes describing agents, which are grouped into several categories. Next, we present the results of a detailed study of all agents for design, which were discussed during the First International Workshop on Agents in Design at MIT in August of 2002. A statistical analysis of their attributes has been conducted and its results are reported to suggest future evolution of agents in design. Finally, we briefly overview the topic of Directed Evolution and use its paradigms to predict further development of agents in design. The paper also provides our initial conclusions and suggests further research. 1. INTRODUCTION The word agent is commonly understood to be an entity acting on behalf of another entity. Similarly, a software agent is usually described as a computer system to which a user can delegate tasks. Such computer systems are expected to be operational over relatively long time periods and to be at least semi-autonomous. The difference between an agent and a program is not only technical, but also social. An agent is a program that is perceived more as an organism, or autonomous entity, whereas a program is just a tool. Thus, most of the agent's features can be implied from this statement. An agent, being a self-contained unit, must not entirely rely on the external control, but rather take initiative on its own. It has to actively look for information (for example by querying, asking, using sensors) and take actions to affect the environment (or other agents). Minsky claims that intelligence emerges from such interaction and that intelligence is observable only " in the eye of the beholder [1]. While a program can be described in simple terms as having a sequence of instructions, an agent would rather have a
A Microcontroller Based Four Fingered Robotic Hand

In this paper we deal with the design and development of a Four Fingered Robotic Hand (FFRH) using 8-bit microcontroller, sensors and wireless feedback. The design of the system is based on a simple, flexible and minimal control strategy. The robot system has 14 independent commands for all the four fingers open and close, wrist up and down, base clockwise and counter clockwise, Pick and Place and Home position to move the fingers. Implementation of pick and place operation of the object using these commands are discussed. The mechanical hardware design of the Robotic hand based on connected double revolute joint mechanisms is briefed. The tendoning system of the double revolute joint mechanism and wireless feedback network provide the hand with the ability to confirm to object topology and therefore providing the advantage of using a simple control algorithm. Finally, the results of the experimental work for pick and place application are enumerated.
Sharp Oracle Inequalities for High-Dimensional Matrix Prediction

We observe (Xi,Yi)i=1n where the Yi's are real valued outputs and the Xi's are m × T matrices. We observe a new entry X and we want to predict the output Y associated with it. We focus on the high-dimensional setting, where mT ≫ n. This includes the matrix completion problem with noise, as well as other problems. We consider linear prediction procedures based on different penalizations, involving a mixture of several norms: the nuclear norm, the Frobenius norm and the ℓ1-norm. For these procedures, we prove sharp oracle inequalities, using a statistical learning theory point of view. A surprising fact in our results is that the rates of convergence do not depend on m and T directly. The analysis is conducted without the usually considered incoherency condition on the unknown matrix or restricted isometry condition on the sampling operator. Moreover, our results are the first to give for this problem an analysis of penalization (such as nuclear norm penalization) as a regularization algorithm: our oracle inequalities prove that these procedures have a prediction accuracy close to the deterministic oracle one, given that the reguralization parameters are well-chosen.
Extracting knowledge from the p53 mutation database: the influence of tabagism in the somatic mutations profile of lung cancer subjects

This work analyses a p53 mutation database aiming to unveil whether of not tabagism can influence the mutation profile of lung cancer patients. We analyzed both the frequency of single nucleotide mutations and the frequency of site (exon) mutations. For the database used, we conclude that tabagism produces more dramatic and unexpected mutations in the DNA sequence of p53.
Input and output queueing ATM switch with backpressure mode and queue loss mode for nonuniform traffic

An input and output queueing ATM switch model with a backpressure (BP) mode and a queue loss (QL) mode to decrease the system delay and the cell loss probability under nonuniform traffic is proposed. In the proposed model, the QL mode is adopted if the size of the backpressure exceeds the threshold. We consider a synchronous system with Bernoulli arrivals under hot-spot traffic that consists of a single output port of higher access rate superimposed on a background uniform traffic. The system delay and cell loss probability are analyzed under hot-spot traffic. It is shown that the proposed model is useful for nonuniform traffic. We also evaluate the effects of the threshold of the backpressure size for adopting the QL mode on the performance, and consider the optimum value of the threshold. © 1998 Scripta Technica, Electron Comm Jpn Pt 1, 81(11): 14–23, 1998
Yield of yearly routine physical examination in HIV-1 infected patients is limited: A retrospective cohort study in the Netherlands

Background Routine physical examinations might be of value in HIV-infected patients, but the yield is unknown. We determined the diagnoses that would have been missed without performing annual routine physical examinations in HIV-infected patients with stable disease. Methods Data were collected from the medical records of 299 HIV-1-infected patients with CD4 count >350 cells/mm3 if not using combination antiretroviral therapy (cART), or CD4 count >100 cells/mm3 and undetectable viral load if using cART. We defined the diagnoses that would have been missed without performing routine physical examinations on annual check-ups in 2010. Exclusion criteria were hepatitis B/C co-infection, start/ switch of cART < 24 weeks, pregnancy, and transgenderism. Results 215 patients (72%) had positive findings: lipodystrophy (30%), lymphadenopathy (16%) and hypertension (8.4%) were the most common. Two-thirds of all findings were not new or were based on complaints indicating a physical examination even if not routinely scheduled. For 24 patients (8.0%) the routine physical examination led to the finding of a new diagnosis: six—all men who have sex with men (MSM)—had a concurrent sexually transmitted infection, eight had hypertension, and ten others had a large variety of diagnoses. A total atrioventricular block with bradycardia was the most clinically relevant finding. Conclusions Annual physical examinations of HIV-infected patients with stable disease brought few new diagnoses that would have been missed without performing a routine examination. Our results suggest that standard assessments could be restricted to six-monthly measuring blood pressure in all patients and annually performing anogenital and digital rectal examination on MSM.
Predicting risk of osteoporotic and hip fracture in the United Kingdom: prospective independent and external validation of QFractureScores

Objective To evaluate the performance of the QFractureScores for predicting the 10 year risk of osteoporotic and hip fractures in an independent UK cohort of patients from general practice records. Design Prospective cohort study. Setting 364 UK general practices contributing to The Health Improvement Network (THIN) database. Participants 2.2 million adults registered with a general practice between 27 June 1994 and 30 June 2008, aged 30-85 (13 million person years), with 25 208 osteoporotic fractures and 12 188 hip fractures. Main outcome measures First (incident) diagnosis of osteoporotic fracture (vertebra, distal radius, or hip) and incident hip fracture recorded in general practice records. Results Results from this independent and external validation of QFractureScores indicated good performance data for both osteoporotic and hip fracture end points. Discrimination and calibration statistics were comparable to those reported in the internal validation of QFractureScores. The hip fracture score had better performance data for both women and men. It explained 63% of the variation in women and 60% of the variation in men, with areas under the receiver operating characteristic curve of 0.89 and 0.86, respectively. The risk score for osteoporotic fracture explained 49% of the variation in women and 38% of the variation in men, with corresponding areas under the receiver operating characteristic curve of 0.82 and 0.74. QFractureScores were well calibrated, with predicted risks closely matching those across all 10ths of risk and for all age groups. Conclusion QFractureScores are useful tools for predicting the 10 year risk of osteoporotic and hip fractures in patients in the United Kingdom.
Compress-Forward Coding With BPSK Modulation for the Half-Duplex Gaussian Relay Channel

This paper studies compress-forward (CF) coding with BPSK modulation for the half-duplex Gaussian relay channel. In CF relaying, Wyner-Ziv coding is applied at the relay to exploit the joint statistics between signals at the relay and the destination. We propose Slepian-Wolf coded nested scalar quantization (SWCNSQ) for practical Wyner-Ziv coding at the relay. We first provide the achievable rate of SWCNSQ based CF relaying as a performance benchmark, and then present a practical code design using low-density parity-check (LDPC) codes for error protection at the source, and nested scalar quantization plus irregular-repeat accumulation (IRA) codes for CF coding at the relay. The degree distributions of the LDPC and IRA codes are optimized using extrinsic information transfer charts and Gaussian approximation. Under discretized density evolution for asymptotically large block lengths, our optimized code design operates 0.11-0.21 dB away from the SWCNSQ limit for CF relaying. Simulations with LDPC/IRA codes of length 2 times 105 bits show a performance gap of 0.27-0.38 dB from the achievable rate.
