Distributed Load Balancing in Heterogeneous Peer-to-Peer Networks for Web Computing Libraries

In this work we present a novel architecture for distributed computing in a peer-to-peer network. In particular, we realize the Paderborn University BSP-based Web Computing Library (PUBWCL), which was formerly used as a centralized client-server architecture for scheduling and load balancing, as a pure peer-to-peer system. By using distributed heterogeneous hash tables (DHHT), our architecture features scheduling and load balancing of tightly coupled, massively parallel algorithms in the bulk-synchronous (BSP) style with a minimal number of migrations. Furthermore, our architecture is capable of heterogeneous BSP programs whereas the former version of PUBWCL could only handle homogeneous BSP programs
Transformation Of Family Ideology In Upper Middle Class Families In Urban South Korea

processes and class processes (Fraad, Resnick, and Wolff 1989), this study analyzes the historical development of the inter-relationships between two major social institutions (that is, the family and the state). It also investigates the ways in which the structure of the upper-middle-class family and women's experience of family life have been transformed as late-industrial capitalism has developed in South Korea. The study is based on ethnographic research of 72 upper-middle-class families conducted in 1990 in Seoul, Korea. I established contacts with these families through personal networks, such as relatives and friends. Without these personal networks, this study would have been impossible due to the reluctance of the families in this social category toward any type of public examination. Throughout this article, the term, class, is used in the Weberian sense of status more than according to the Marxian conception of class. Upper-middle-class families in this study live in expensive condominium complexes that are recently established in the Kangnam (south of the Han river) area and share a variety of social status indicators, such as income and occupation of the male head of the family, ownership of family property, size of the condominium, monthly household budget, educational level of family members, and life-styles. The majority of the male heads of the families I studied are white-collar workers, such as managers or executives of private companies (46.5 per cent), entrepreneurs (25.6 per cent), professionals (13.7 per cent), high-level government officials (6.8 per cent), and other (7.4 per cent). Every family in my sample has one or more kinds of family property, such as stocks, cash savings, land, second homes and condominiums, and office buildings. Seventy-five per cent of the families live in the condominiums that are valued at more than half a million U.S. dollars. They are spacious and roomy condominiums, relative to the South Korean standard; i.e., larger than 40 pyung (1,212 m2) up to 61 pyong (1,848 m2), and have more than four bedrooms. Monthly household expenses of the families, which are primarily based on the income of male heads, is well above the average household budget of the
ROTATING NEUTRON STAR MODELS WITH MAGNETIC FIELD

We present the first numerical solutions of the coupled Einstein-Maxwell equations describing rapidly rotating neutron stars endowed with a magnetic field. These solutions are fully relativistic and self-consistent, all the effects of the electromagnetic field on the star's equilibrium (Lorentz force, spacetime curvature generated by the electromagnetic stress-energy) being taken into account. The magnetic field is axisymmetric and poloidal. Five dense matter equations of state are employed. The partial differential equation system is integrated by means of a pseudo-spectral method. Various tests passed by the numerical code are presented. The effects of the magnetic field on neutron stars structure are then investigated, especially by comparing magnetized and non-magnetized configurations with the same baryon number. The deformation of the star induced by the magnetic field is important only for huge values of B (B>10^{10} T). The maximum mass as well as the maximum rotational velocity are found to increase with the magnetic field. The maximum allowable poloidal magnetic field is of the order of 10^{14} T (10^{18} G) and is reached when the magnetic pressure is comparable to the fluid pressure at the centre of the star. For such values, the maximum mass of neutron stars is found to increase by 13 to 29 % (depending upon the EOS) with respect to the maximum mass of non-magnetized stars.
The Breath Segment in Expressive Speech

This paper, based on a selected one hour of expressive speech, is a pilot study on how to use breath segments to get more natural and expressive speech. It mainly deals with the status of when the breath segments occur and how the acoustic features are affected by the speaker ’s emotional states in terms of valence and activation. Statistical analysis is made to investigate the relationship between the length and intensity of the breath segments and the two state parameters. Finally, a perceptual experiment is conducted by employing the analysis results to synthesized speech, the results of which demonstrate that breath segment insertion can help improve the expressiveness and naturalness of the synthesized speech.
Ii Chain Controls the Transport of Major Histocompatibility Complex Class II Molecules to and from Lysosomes

Major histocompatibility complex class II molecules are synthesized as a nonameric complex consisting of three αβ dimers associated with a trimer of invariant (Ii) chains. After exiting the TGN, a targeting signal in the Ii chain cytoplasmic domain directs the complex to endosomes where Ii chain is proteolytically processed and removed, allowing class II molecules to bind antigenic peptides before reaching the cell surface. Ii chain dissociation and peptide binding are thought to occur in one or more postendosomal sites related either to endosomes (designated CIIV) or to lysosomes (designated MIIC). We now find that in addition to initially targeting αβ dimers to endosomes, Ii chain regulates the subsequent transport of class II molecules. Under normal conditions, murine A20 B cells transport all of their newly synthesized class II I-Ab αβ dimers to the plasma membrane with little if any reaching lysosomal compartments. Inhibition of Ii processing by the cysteine/serine protease inhibitor leupeptin, however, blocked transport to the cell surface and caused a dramatic but selective accumulation of I-Ab class II molecules in lysosomes. In leupeptin, I-Ab dimers formed stable complexes with a 10-kD NH2-terminal Ii chain fragment (Ii-p10), normally a transient intermediate in Ii chain processing. Upon removal of leupeptin, Ii-p10 was degraded and released, I-Ab dimers bound antigenic peptides, and the peptide-loaded dimers were transported slowly from lysosomes to the plasma membrane. Our results suggest that alterations in the rate or efficiency of Ii chain processing can alter the postendosomal sorting of class II molecules, resulting in the increased accumulation of αβ dimers in lysosome-like MIIC. Thus, simple differences in Ii chain processing may account for the highly variable amounts of class II found in lysosomal compartments of different cell types or at different developmental stages.
Electronic Word-of-mouth via Twitter - Customer eWOM Motivations and Intentions

The study aims to explore customers’ motivational factors to express their opinions in Twitter regarding company performance, products and services. Using Twitter as the main medium of the study, an electronic questionnaire has been implemented to gather data. A total of 1,192 complete valid responses have been collected from 5,011 hits on Twitter. Data were statistically analyzed to extract the strongest factors. The results show that consumers are driven by multiple motives. Concern for Other Consumers, Extraversion/Positive Self Enhancement, Venting Negative Feelings and Helping the Company are the primary factors. Furthermore, we have identified early symptoms of grouped eWOM in Twitter against and in favour of companies which carry an important message to companies regarding the need to formulate proactive strategies to deal the with upcoming trend of Twitter powers for companies. The study was carried
Kindergarten Children's Discrimination and Production of Phonemes in Isolation and in Words.

Fifty kindergarten children's ability to discriminate and produce the phonemes typically used in early phonics-based reading instruction was investigated in an AB-X discrimination task and an echoic pbduction task. The phonemes were presented in isolation and in a word context in both tasks to each child. It was found that (1) more discrimination than production errors were made, a difference which was reliable only for the vowels, (2) vowels were easier to discriminate and produce than consonants, and (3) phonemes errors were fewer in words than in isolation, a difference which reached significance only in the production d ta. Most importantly, further data analyses revealed that frequency of a phoneme in the conversational speech of kindergarteners and in the lexicon of the Southwest Regional Laboratory First Year Communication Skills program did not predict articulation difficulty of a phoneme either in words or isolation q Implications of the results for reading pedagogy are discussed. 'Gary Vern's help with the'statistical analyses is greatly appreciated. _,
Prevalence of Psychiatric Disorders in a Sample of Elderly Residents in Rural and Urban Population of Zulfi Region - Saudi Arabia

The population of the world is aging rapidly, because of increasing life expectancy and falling birth rates This age is also more prone to have chronic diseases and hence there is a need to ensure that the health and social support to these individuals is available. Mental illness represents an important public health problem. Local-level data concerning mental illness in different populations provides the evidence-base for public health authorities to plan, implement and evaluate control programs. Aims: to estimate the prevalence of psychiatric disorders among the elderly in this region and to analyze for differences between urban and rural areas and also identify and suggest some risk factors for these disorders. Methodology: The study was done in Zulfi region of Saudi Arabia. The sample size of rural & urban study was 550&392 persons from 65 years and more, respectively. Instruments and procedures: All the participants of the study were given a general health questionnaire, a symptom check list, a questionnaire to assess the social and economic level and a Structured clinical interview for DSM –IV (SCID) Results: The psychiatric symptoms among elderly in this study according to SCL 90 were not seen in 15.56% in urban people and 40.4% in rural area. The most prevalent psychiatric disorder in urban area is dysthymia 19.37% while the most prevalent psychiatric disorder in rural area is adjustment disorder with depressed mood at 14%.
Distributed Subgradient Projection Algorithm Over Directed Graphs

We propose Directed-Distributed Projected Subgradient (D-DPS) to solve a constrained optimization problem over a multi-agent network, where the goal of agents is to collectively minimize the sum of locally known convex functions. Each agent in the network owns only its local objective function, constrained to a commonly known convex set. We focus on the circumstance when communications between agents are described by a <italic>directed</italic> network. The D-DPS combines surplus consensus to overcome the asymmetry caused by the directed communication network. The analysis shows the convergence rate to be <inline-formula><tex-math notation="LaTeX">$O(\frac{\ln k}{\sqrt{k}})$</tex-math> </inline-formula>.
Hybrid Feedback-Based Access Scheme for Cognitive Radio Systems

In this paper, a cognitive radio system is studied in which the secondary user (SU) leverages the primary user (PU) channel quality indicator feedback (CQI) and the PU automatic repeat request (ARQ). The SU randomly accesses the PU channel with access probabilities based on its spectrum sensing outcome and the PU feedbacks. The SU's access probabilities are selected though an optimization problem with the objective to maximize the SU's throughput while ensuring the stability of the PU's packet queue. This system is modeled using a multidimensional Markov chain. This model enabled us to derive a closed-form expression for the SU's throughput, which is used in the throughput maximization problem. The proposed scheme is shown to improve the SU service rate compared to the system where no PU feedback is exploited by the SU, the system where the SU utilizes only the PU CQI feedback, and the system where the SU utilizes only the PU ARQ feedback.
Contribution of the Home Environment to Preschool Children's Emergent Literacy Skills.

Contribution of the Home Environment to Preschool Children’s Emergent Literacy Skills. (August 2010) Rebekah Mina Haynes, B.S., Baylor University Chair of Advisory Committee: Dr. Jorge E. Gonzalez Recent and ongoing research has demonstrated the alarming likelihood of children from low-income homes and from ethnic minorities to read at much lower reading levels than their peers. Additionally, reading ability is related to the earliest of emergent literacy skills, which can be measured in young children before they enter formal schooling. The home environment, including the available resources, support for literacy and school, and the parent-child relationship, plays an important role in promoting the development of emergent literacy skills. More research is needed, however, to inform programs and researchers about the specific relationship between the home environment and emergent literacy development. The current study was conducted using a sample of 122 preschool children enrolled in ERF enriched preschool classrooms in one school located in a Southwestern state. The study investigated the power of three variables of the home literacy environment (HLE) (i.e., Family Reading and Writing, External Resources, and Daily Activities) to predict three emergent literacy outcomes (i.e., receptive oral language, alphabet knowledge, and name writing) using canonical correlation analysis (CCA).

A measurement framework for pin-pointing routing changes

Changes in the end-to-end path between two hosts can lead to sudden changes in the round-trip time and available bandwidth, or even the complete loss of connectivity. Determining the reason for the routing change is crucial for diagnosing and fixing the problem, and for holding a particular domain accountable for the disruption. Active measurement tools like traceroute can infer the current path between two end-points, but not where and why the path changed. Analyzing BGP data from multiple vantage points seems like a promising way to infer the root cause of routing changes. In this paper, we explain the inherent limitations of using BGP data alone and argue for a distributed approach to troubleshooting routing problems. We propose a solution where each AS continuously maintains a view of routing changes in its own network, without requiring additional support from the underlying routers. Then, we describe how to query the measurement servers along the AS-level forwarding path from the source to the destination to uncover the location and the reason for the routing change.
Automatic Extrinsic Calibration of Vision and Lidar by Maximizing Mutual Information

This paper reports on an algorithm for automatic, targetless, extrinsic calibration of a lidar and optical camera system based upon the maximization of mutual information between the sensor‐measured surface intensities. The proposed method is completely data‐driven and does not require any fiducial calibration targets—making in situ calibration easy. We calculate the Cramér‐Rao lower bound (CRLB) of the estimated calibration parameter variance, and we show experimentally that the sample variance of the estimated parameters empirically approaches the CRLB when the amount of data used for calibration is sufficiently large. Furthermore, we compare the calibration results to independent ground‐truth (where available) and observe that the mean error empirically approaches zero as the amount of data used for calibration is increased, thereby suggesting that the proposed estimator is a minimum variance unbiased estimate of the calibration parameters. Experimental results are presented for three different lidar‐camera systems: (i) a three‐dimensional (3D) lidar and omnidirectional camera, (ii) a 3D time‐of‐flight sensor and monocular camera, and (iii) a 2D lidar and monocular camera.
Psychological Predictors of Glucose Control in Patients With IDDM

I nsulin-dependent diabetes mellitus (IDDM) patients vary considerably in response to conventional insulin therapy, and investigators have attempted to predict these individual differences in glycemic control using various psychological instruments. Although some modest predictors of glycosylated hemoglobin (GHb) have been identified (1), the observed correlations, although statistically significant, have been too small to be of practical clinical value in identifying IDDM patients who are likely to exhibit poor glucose control. We have conducted a series of studies to identify individual difference measures relevant to the potential role of stress reactivity in glycemic disregulation. Measurements of the type A behavior pattern (impatience, competitiveness) predicted glycemic responses to a laboratory stressor in a sample of school-aged IDDM patients (2). However, the same measure failed to predict chronic glucose regulation assessed by GHb (3). This study continues this research. Additional questionnaire measures characterizing traits relevant to behavioral and physiological reactivity were collected from a group of IDDM patients and correlated with GHb levels. Attention focused on the temperamental traits of anger, anxiety, extraversion, and neuroticism (emotional lability), which were hypothesized to contribute to increased emotional reactivity in daily life. In addition, a subset of these subjects monitored blood glucose (BG) levels for 14 days at home using a glucose-monitoring instrument with memory that provided additional measures of chronic glucose regulation and information regarding adherence to the BG-monitoring regimen.
Sources of Economic Distress

Examined in this article are relationships between six measures of economic stress—financial adequacy, perceived economic well-being, respondent's and partner's job instability, and respondent's and partner's job insecurity—and seven measures of individual and family well-being. Presented are descriptive and regression analyses of social survey data drawn from telephone interviews with 366 householders ages 18 to 65 residing in a southeastern U.S. metropolitan county. For both women and men, perceived economic well-being was generally the strongest predictor of measures of individual and family well-being. For men as well as women, spouse's or partner's job variables were important predictors of measures of family well-being. The respondent's own job instability and insecurity appeared more important to women than men, and more so for family than individual well-being outcomes. Two alternative pathways were proposed and partially supported for the influence of economic factors on individual well-being.
Human Fc gamma receptor IIA (FcγRIIA) genotyping and association with systemic lupus erythematosus (SLE) in Chinese and Malays in Malaysia

SLE is an autoimmune and polygenic disorder characterized by an accumulation and deposition of immune complexes. Several studies have indicated differential impact of FcgR polymorphism genotypes in different ethnic groups studied. The Fc receptor for IgG class IIA gene (FcγRIIA) occurs in two allelic forms. The allele FcγRIIA-H131 encodes a receptor with a histidine at the 131 amino acid position; the other allele FcgRIIA-R131 encodes an arginine. This polymorphism is believed to determine the affinity of the receptor for hIgG2 in immune complexes. FcγRIIA-H131 has a higher capacity for hIgG2 compared to FcγRIIA-R131 as measured by in vitro studies of insoluble immune complex clearance. We have investigated the polymorphism for FcγRIIA using a novel polymerase chain reaction-allele specific primer(PCR-ASP) method designed specifically to distinguish the two allelic forms. Our studies were based on 175 Chinese and 50 Malays SLE patients as well as 108 and 50 ethnically matched healthy controls for the respective groups. Analysis of the data (w2 test with Yates correction factors and odds ratios) revealed that there were no significant differences between SLE patients and controls. We have not found evidence of a protective effect conferred by FcγRIIA-H131 in the ethnic groups studied.
Multisite campaign on the open cluster M67 – I. Observations and photometric reductions

We report on an ambitious multisite campaign aimed at detecting stellar variability, particularly solar-like oscillations, in the red giant stars in the open cluster M67 (NGC 2682). During the six-week observing run, which comprised 164 telescope nights, we used nine 0.6-m to 2.1-m class telescopes located around the world to obtain uninterrupted time series photometry. We outline here the data acquisition and reduction, with emphasis on the optimization of the signal-to-noise ratio of the low-amplitude (50-500 μmag) solar-like oscillations. This includes a new and efficient method for obtaining the linearity profile of the CCD response at ultrahigh precision (∼10 parts per million). The noise in the final time series is 0.50 mmag per minute integration for the best site, while the noise in the Fourier spectrum of all sites combined is 20 μmag. In addition to the red giant stars, this data set proves to be very valuable for studying high-amplitude variable stars such as eclipsing binaries, W UMa systems and δ Scuti stars.
Tryptophan-Accelerated Electron Flow Through Proteins

Energy flow in biological structures often requires submillisecond charge transport over long molecular distances. Kinetics modeling suggests that charge-transfer rates can be greatly enhanced by multistep electron tunneling in which redox-active amino acid side chains act as intermediate donors or acceptors. We report transient optical and infrared spectroscopic experiments that quantify the extent to which an intervening tryptophan residue can facilitate electron transfer between distant metal redox centers in a mutant Pseudomonas aeruginosa azurin. CuI oxidation by a photoexcited ReI-diimine at position 124 on a histidine(124)-glycine(123)-tryptophan(122)-methionine(121) β strand occurs in a few nanoseconds, fully two orders of magnitude faster than documented for single-step electron tunneling at a 19 angstrom donor-acceptor distance.
