A comprehensive survey of security mechanisms in healthcare applications

Recent trends and the accurate knowledge of human anatomy allow the healthcare professionals to handle the emergency scenario. Remote monitoring of patients by the healthcare professionals or doctors through the utilization of Wireless Sensor Network (WSN) offers the solution to the shortage problem. The special form of WSN used for remote monitoring called Wireless Body Area Network (WBAN) or Wireless Medical Sensor Network (WMSN) utilizes the numerous sensors that collect the data from the human body and send it to the central device for processing (raising the alarm for anomalies detection) and storage. This paper presents the survey of WMSN topologies, data sharing mechanisms, cryptography and attributes-based encryption in privacy preserving in detail. The survey addresses the issues in cryptographic approaches such as storage / computational overhead, the trade-off between the security and elasticity, trust assurance against the attacks respectively. The detailed survey conveys that the secure data transfer from the user to the server is the major issue against the several inside and outside attackers. The processes involved in cryptography mechanisms such as key generation, encryption, and decryption introduces the storage and computational overheads and delegation issues in data preserving. To overcome these issues, the trusted authority and the hash verifier is included to generate and exchange the keys. Besides, the trade-off between the security and overhead reduction is still investigating the issue in the healthcare applications.
Design Consideration to Reduce Cogging Torque in Axial Flux Permanent-Magnet Machines

In designing new topologies for permanent-magnet machines based on rare earth magnets, it is necessary to diminish the undesired cogging torque. This paper presents a 3-D finite-element analysis to evaluate the effect of magnet shape and stator displacement on cogging torque reduction, for axial flux machines. It analyzes the final electromagnetic torque for the proposed configurations. Finally, it presents the resultant cogging torque waveform for a 5.0 kW prototype, based on our optimization techniques.
Serological and Clinicopathological Studies on Leptospirosis Among Sheep

The present study was carried out to investigate occurrence, serovar distribution and clinicopathological attributes of leptospirosis among sheep from South Gujarat. A total of 41 blood and serum samples were randomly collected from apparently healthy and clinically ailing sheep of different breeds and age of either sex, reared in different flocks. Seropositivity was found to be 12.20% among sheep using the Microscopic Agglutination Test (MAT). Among clinically ailing and apparently healthy sheep, seropositivity was found to be 4.35% (1/23) and 22.22% (4/18), respectively with involvement of serovars Pomona, Canicola and Icterohaemorrhagiae. The hemato-biochemical and urinalyses results showed variation among seropositive and seronegative animals however, these differences were non-significant. The study indicated seropositivity with serovar Pomona as main leptospiral serovar among sheep in South Gujarat, however, the specific conclusion on clinicopathological aspect could not be made. Though for prevention and control of the disease where an obvious alteration in the serovars causing the disease is common further epidemiological study is necessary.
Effects of different mating scenarios on embryo viability in brown trout

Mating with attractive or dominant males is often predicted to offer indirect genetic benefits to females, but it is still largely unclear how important such non‐random mating can be with regard to embryo viability. We sampled a natural population of adult migratory brown trout (Salmo trutta), bred them in vitro in a half‐sib breeding design to separate genetic from maternal environmental effects, raised 2098 embryos singly until hatching, and exposed them experimentally to different levels of pathogen stress at a late embryonic stage. We found that the embryos’ tolerance to the induced pathogen stress was linked to the major histocompatibility complex (MHC) of their parents, i.e. certain MHC genotypes appeared to provide better protection against infection than others. We also found significant additive genetic variance for stress tolerance. Melanin‐based dark skin patterns revealed males with ‘good genes’, i.e. embryos fathered by dark coloured males had a high tolerance to infection. Mating with large and dominant males would, however, not improve embryo viability when compared to random mating. We used simulations to provide estimates of how mate choice based on MHC or melanin‐based skin patterns would influence embryos’ tolerance to the experimentally induced pathogen stress.
The Hypnotic Diagnostic Interview for Hysterical Disorders, Pediatric Form

Abstract This article reports on the use of hypnosis to facilitate the diagnostic process in two cases of pediatric hysterical reactions. The Hypnotic Diagnostic Interview for Hysterical Disorders (HDIHD), an interview tool, specifically designed for these cases, is reported. The first case was an adolescent male with motor Conversion Disorder manifested as paralysis of his lower limbs. The second was a preadolescent girl with sensory Conversion Disorder manifested as reduction of visual field in her right eye. Freudian conceptualization of hysterical reactions was employed as the conceptual basis in the formulation of these cases. This orientation posits hysterical phenomena a psychological defense employed by individuals exposed to traumatic experiences in order to effectuate a defense from intolerable affective material. The emotionally overwhelming material converts into physical reactivity free of the traumatic consequences by keeping the intolerable images and emotions deeply repressed within the subconscious. As the focus on these cases was diagnostic, treatment efforts were avoided. As it turned out, environmental interventions, based on the obtained information from the hypnotic interviews, extinguished the symptoms. The children were symptom free at follow-up.
Similar-Shape Retrieval in Shape Data Management

Addresses the problem of similar-shape retrieval, where shapes or images in a shape database that satisfy specified shape-similarity constraints with respect to the query shape or image must be retrieved from the database. In its simplest form, the similar-shape retrieval problem can be stated as, "retrieve or select all shapes or images that are visually similar to the query shape or the query image's shape". We focus on databases of 2D shapes-or equivalently, databases of images of flat or almost flat objects. (We use the terms "object" and "shape" interchangeably). Two common types of 2D objects are rigid objects, which have a single rigid component called a link, and articulated objects, which have two or more rigid components joined by movable (rotating or sliding) joints. An ideal similar-shape retrieval technique must be general enough to handle images of articulated as well as rigid objects. It must be flexible enough to handle simple query images, which have isolated shapes, and complex query images, which have partially visible, overlapping or touching objects. We discuss the central issues in similar-shape retrieval and explain how these issues are resolved in a shape retrieval scheme called FIBSSR (Feature Index-Based Similar-Shape Retrieval). This new similar-shape retrieval system effectively models real-world applications. >
Coordinate singularities in harmonically sliced cosmologies

Harmonic slicing has in recent years become a standard way of prescribing the lapse function in numerical simulations of general relativity. However, as was first noticed by Alcubierre (1997), numerical solutions generated using this slicing condition can show pathological behaviour. In this paper, analytic and numerical methods are used to examine harmonic slicings of Kasner and Gowdy cosmological spacetimes. It is shown that in general the slicings are prevented from covering the whole of the spacetimes by the appearance of coordinate singularities. As well as limiting the maximum running times of numerical simulations, the coordinate singularities can lead to features being produced in numerically evolved solutions which must be distinguished from genuine physical effects.
An extension theory for a certain class of loops

Introduction. If £ is a group with a normal subgroup K one may form the quotient group E/K^M. Conversely, for preassigned groups K, M, there is the extension problem: to determine (in some sense) all groups E with K as normal subgroup such that E/K^M. Much progress has been made on this problem, particularly through the work of Baer [l, 2, 3] and the cohomology theory of Eilenberg and MacLane [l, 2, 3]. The latter authors make it clear that insight is gained by relinquishing part of the associative law; specifically, by requiring that E be merely a loop such that the associative law (̂ 1̂ 2)̂ 3 = 1̂(̂ 2̂ 3) holds if at least one of the e% belongs to a distinguished subgroup of K. We take this to be K itself. It then becomes evident that the subclass of loops E consisting of the groups is not the only one of interest; one may consider, for example, the Moufang loops, in which case it seems natural to allow M also to be Moufang. Thus we approach the extension problem actually studied in the paper: M is a given loop, K is a group (not given, but with given centre G) and E is to be any loop with l a s a normal subloop contained in the "associator" of E, such that E/K=M. This problem is more typical of group theory than of loop theory but is, nevertheless, a natural and significant special topic in the theory of loops. For the sake of brevity no examples or applications are given and references to the bibliography are kept to a minimum. The EilenbergMacLane kernels, important for constructions, have been ignored. I may signal out as new: the inverse of a (noncentral) extension (§1), the specific results on central Moufang extensions (§6) and the allpervading functions F which generalize (even for M a group) the Eilenberg-MacLane cocycles. As indicated by Theorem 8 (§4), additional information about the functions F would probably increase our knowledge of cohomology groups.
Chromatin Immunoprecipitation (ChIP) in Mouse T-cell Lines

Signaling pathways regulate gene expression programs via the modulation of the chromatin structure at different levels, such as by post-translational modifications (PTMs) of histone tails, the exchange of canonical histones with histone variants, and nucleosome eviction. Such regulation requires the binding of signal-sensitive transcription factors (TFs) that recruit chromatin-modifying enzymes at regulatory elements defined as enhancers. Understanding how signaling cascades regulate enhancer activity requires a comprehensive analysis of the binding of TFs, chromatin modifying enzymes, and the occupancy of specific histone marks and histone variants. Chromatin immunoprecipitation (ChIP) assays utilize highly specific antibodies to immunoprecipitate specific protein/DNA complexes. The subsequent analysis of the purified DNA allows for the identification the region occupied by the protein recognized by the antibody. This work describes a protocol to efficiently perform ChIP of histone proteins in a mature mouse T-cell line. The presented protocol allows for the performance of ChIP assays in a reasonable timeframe and with high reproducibility.
Functional Copies of the Mst77F Gene on the Y Chromosome of Drosophila melanogaster

The Y chromosome of Drosophila melanogaster has <20 protein-coding genes. These genes originated from the duplication of autosomal genes and have male-related functions. In 1993, Russell and Kaiser found three Y-linked pseudogenes of the Mst77F gene, which is a testis-expressed autosomal gene that is essential for male fertility. We did a thorough search using experimental and computational methods and found 18 Y-linked copies of this gene (named Mst77Y-1–Mst77Y-18). Ten Mst77Y genes encode defective proteins and the other eight are potentially functional. These eight genes produce ∼20% of the functional Mst77F-like mRNA, and molecular evolutionary analysis shows that they evolved under purifying selection. Hence several Mst77Y genes have all the features of functional genes. Mst77Y genes are present only in D. melanogaster, and phylogenetic analysis confirmed that the duplication is a recent event. The identification of functional Mst77Y genes reinforces the previous finding that gene gains play a prominent role in the evolution of the Drosophila Y chromosome.
Testosterone decreases the expression of endometrial pinopode and L-selectin ligand (MECA-79) in adult female rats during uterine receptivity period.

UNLABELLED Pinopode, a progesterone-dependent endometrial projection which appears during uterine receptivity period, participates in blastocyst implantation. Blastocyst loosely attaches to pinopode via L-selectin ligand (MECA-79). We hypothesized that pinopode and MECA-79 expressions were affected by testosterone. Therefore, the effect of testosterone on pinopode and MECA-79 expressions during uterine receptivity period were investigated. METHODS Ovariectomized adult female rats received 8 days sex-steroid replacement intended to mimic hormonal changes in early pregnancy with day 6 to 8 represents uterine receptivity period. Testosterone (1 mg/kg/day) was injected together with flutamide or finasteride during the period of uterine receptivity. At the end of treatment, rats were sacrificed and uteri were removed. The existence of pinopodes in the endometrium was visualized by electron microscopy and uterine expression and distribution of MECA-79 protein were examined by Western blotting and immunohistochemistry (IHC) respectively. RESULTS Abundant pinopodes and MECA-79 expressions were observed in rats received normal steroid replacement regime. Administration of testosterone during uterine receptivity period reduced pinopodes and MECA-79 expressions, which were antagonized by flutamide and not finasteride. CONCLUSIONS The decrease in uterine pinopodes and MECA-79 expressions during uterine receptivity period by testosterone may cause failure of blastocyst to implant in conditions associated with high level of this hormone.
The Sweet Burden: Young consumers' extroversion, number of friendship on online social network and luxury consumption tendency

The purpose of this paper is to build a model consisting of young consumers' personality, the use of online social network, and the luxury consumption tendency. We collected data from users of a popular online social network site in China, renren.com, which is Facebook copy. Over 150 respondents from two leading Chinese universities, respectively located at Beijing and Shanghai, volunteered to participate in the survey. The results indicated that one's extroversion strongly predicted the number of fans on renren. Number of friendship was also strongly associated with his/her luxury consumption tendency, after controlled the gender, grade, disposable income, and frequency of internet use. Moreover, the participants' place of origin (big city vs. small town) served to moderate the relationship, i.e., for young consumers from small towns, their increased extroversion is associated with larger online social network, but at the cost of higher consumption of luxury goods, while the effect on undergraduates from big cities was lessened. These findings offer insight into the influence of consumers' personality on luxury consumption and provide managerial implications for marketers to build luxury businesses in China.
The Effect of Income Inequality and Residential Segregation on Infectious Diseases Transmission

Since the 1980s, income inequality and residential segregation have increased in industrialized and developing countries. There is a body of literature that hypothesizes and examines the relationship between inequality and segregation on health. However, none of these studies constructs a mathematical model to explain these complex linkages. This project builds a theoretical behavioral model that analyzes the effect of income inequality, neighborhood characteristics, and residential segregation on infectious diseases transmission. Residential segregation and income inequality decrease the community’s health if an individual’s health production function is concave with respect to income and exposure. We also discuss the possibility of a disease trap through the existence of multiple equilibria when disease externalities generate convexities in the health production function. Because a complete set of closed-form solutions to our model does not exist, we analyze our model qualitatively using techniques from Real Analysis.
Association of a functional single-nucleotide polymorphism of PTPN22, encoding lymphoid protein phosphatase, with rheumatoid arthritis and systemic lupus erythematosus.

OBJECTIVE To assess the possible association between the PTPN22 gene 1858C-->T polymorphism and the predisposition and clinical expression of 2 systemic autoimmune diseases, rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). METHODS Our study population consisted of 826 RA patients, 338 SLE patients, and 1,036 healthy subjects. All subjects were of Spanish Caucasian origin. Genotyping of the PTPN22 gene 1858C-->T polymorphism was performed by real-time polymerase chain reaction technology, using the TaqMan 5'-allele discrimination assay. RESULTS The overall distribution of genotypes in the RA patients was significantly different from that in the controls (P = 0.005, by chi-square test with 2 x 3 contingency tables). We observed a statistically significant difference in the distribution of the PTPN22 1858T allele between healthy subjects (7.4%), and RA patients (10.4%) (P = 0.001, odds ratio [OR] 1.45 [95% confidence interval (95% CI) 1.15-1.83]). In addition, PTPN22 1858 C/T and T/T genotypes were present at a significantly higher frequency in SLE patients than in controls (P = 0.02, OR 1.55 [95% CI 1.05-2.29]). Differences were also observed when allele frequencies were compared, with the PTPN22 1858T allele being present at a higher frequency among SLE patients (P = 0.03, OR 1.45 [95% CI 1.01-2.09]). CONCLUSION These results suggest that the PTPN22 1858T allele may confer differential susceptibility to RA and SLE in the Spanish population.

Secondary-side adaptive digital controlled series resonant DC-DC converters for low voltage high current applications

It is more difficult for VRMs to supply power to future microprocessors, which need lower supply voltage, large current and large current slew rate. Most of today's VRMs are with inductor-capacitor type output filters. The inductor in the output filter limits the current transient speed. Hence, the secondary-side controlled series resonant converter with capacitor type filter is introduced in this paper to overcome this limitation. The lack of the inductor in its output filter makes it have very quick dynamic response. Also an adaptive control scheme is proposed to control the current-type synchronous MOSFETs, which eliminates the current sensor in the power path. Theoretical analysis and simulation results verify the proposed concept.
Randomly charged polymers: An exact enumeration study.

We perform an exact enumeration study of polymers formed from a (quenched) random sequence of charged monomers ±q0. Such polymers, known as polyampholytes, are compact when completely neutral and expanded when highly charged. Our exhaustive search included all spatial conformations and quenched sequences for up to 12–step (13–site) walks. We investigate the behavior of the polymer as a function of its overall excess charge Q, and temperature T. At low temperatures there is a phase transition from compact to extended configurations when the charge exceeds Qc ≈ q0 √ N. There are also indications of a transition for small Q between two compact states on varying temperature. Numerical estimates are provided for the condensation energy, surface tension, and the critical exponent �.
Comparison of Cell and POWER 5 Architectures for a Flocking Algorithm : A Performance and Usability Study CS 267 Final Project

We have parallelized and optimized an agent-based simulation of emergent flocking behavior for two shared-memory architectures: the POWER5 and the Cell Broadband Engine. The goal of this study was to explore the affordances and trade-offs of both architectures and their available APIs, especially for addressing the load-balancing issues caused by the uneven spatial distribution of flocking agents. We found that for this particular algorithm, the OpenMP API and POWER5 architecture provided higher performance. OpenMP also proved more usable because of its high-level constructs.
Total antioxidant capacity of the diet and major neurologic outcomes in older adults

Objective: To evaluate total antioxidant capacity of the diet, measured by the ferric-reducing antioxidant power (FRAP) assay, in relation to risks of dementia and stroke, as well as key structural brain volumes, in the elderly. Methods: We prospectively studied 5,395 participants in the Rotterdam Study, aged 55 years and older, who were dementia free and provided dietary information at study baseline; 5,285 individuals were also stroke free at baseline, and 462 were dementia and stroke free at the time of an MRI brain scan 5 years after baseline. Dietary data were ascertained using a semiquantitative food-frequency questionnaire, and combined with food-specific FRAP measurements from published tables; this information was aggregated across the diet to obtain “dietary FRAP scores. ” Multivariable-adjusted Cox proportional hazard models were used to estimate relative risks of dementia and stroke, and multivariable-adjusted linear regression was used to estimate mean differences in structural brain volumes, across tertiles of dietary FRAP scores. Results: During a median 13.8 years of follow-up, we identified approximately 600 cases each of dementia and stroke. In multivariable-adjusted models, we observed no associations between dietary FRAP scores and risk of dementia (p trend = 0.3; relative risk = 1.12, 95% confidence interval = 0.91–1.38, comparing the highest vs lowest FRAP tertiles) or risk of stroke (p trend = 0.3; relative risk = 0.91, 95% confidence interval = 0.75–1.11, comparing extreme FRAP tertiles); results were similar across subtypes of these outcomes. Dietary FRAP scores were unrelated to brain tissue volumes as well. Conclusions: Total antioxidant capacity of the diet, measured by dietary FRAP scores, does not seem to predict risks of major neurologic diseases.
