Top-k Search Over Grid File

In the era of huge datasets, the top- search becomes an effective way to decrease the search time of top- objects. Since we suppose locally ac- cessible data only, the multidimensional indexes containing all attributes to- gether seem to be more effective than a distribution of each attribute to a sepa- rate index. Therefore we introduce the top- search algorithm over grid file - the multidimensional index not used for the top- search yet. Grid file does not require computation with all attribute values together like R-tree, R*-tree (i.e. computation of area, perimeter) nor a metric like M-tree. Grid file can be used directly for indexing any type of attributes with natural ordering. Our experi- ments show that grid file, R-tree and R*-tree offer much better performance of the top- search than separated B + -trees and table scan.
Coma after cardiac arrest--how much care is enough?

HEALTH CARE IN THIS NATION has become an enormously complicated affair. This is largely a direct result of the unprecedented advances in medical science and technology that have occurred, particularly over the past 40 years. The technologic result has been dramatic. Medical care in this nation is unsurpassed in what it can accomplish. The social, economic and political result has been a new kind of complex health care system that is unprecedented. Someone has said that it is kind of like a balloon-if you push it in one place it bulges somewhere else, and not much is changed. It has developed characteristics that seem to resist or defy such time-honored approaches as free enterprise, a free market or government regulation and control by laws. Each of these has been or is being tried but none seems to be working very well, if at all. For example, while the costs are perceived to be too high and uncontrolled, at the same time we are told that 40 million Americans have limited access to health care, and may not be receiving it, because they have no health insur-
Improving Post-Click User Engagement on Native Ads via Survival Analysis

In this paper we focus on estimating the post-click engagement on native ads by predicting the dwell time on the corresponding ad landing pages. To infer relationships between features of the ads and dwell time we resort to the application of survival analysis techniques, which allow us to estimate the distribution of the length of time that the user will spend on the ad. This information is then integrated into the ad ranking function with the goal of promoting the rank of ads that are likely to be clicked and consumed by users (dwell time greater than a given threshold). The online evaluation over live traffic shows that considering post-click engagement has a consistent positive effect on both CTR, decreases the number of bounces and increases the average dwell time, hence leading to a better user post-click experience.
Early disease onset is predicted by a higher genetic risk for lupus and is associated with a more severe phenotype in lupus patients

Background Systemic lupus erythematosus (SLE) is a chronic, multiorgan, autoimmune disease that affects people of all ages and ethnicities. Objectives To explore the relationship between age at disease onset and many of the diverse manifestations of SLE. Additionally, to determine the relationship between age of disease onset and genetic risk in patients with SLE. Methods The relationship between the age at disease onset and SLE manifestations were explored in a multi-racial cohort of 1317 patients. Patients with SLE were genotyped across 19 confirmed genetic susceptibility loci for SLE. Logistic regression was used to determine the relationships between the number of risk alleles present and age of disease onset. Results Childhood-onset SLE had higher odds of proteinuria, malar rash, anti-dsDNA antibody, haemolytic anaemia, arthritis and leucopenia (OR=3.03, 2.13, 2.08, 2.50, 1.89, 1.53, respectively; p values <0.0001, 0.0004, 0.0005, 0.0024, 0.0114, 0.045, respectively). In female subjects, the odds of having cellular casts were 2.18 times higher in childhood-onset than in adult-onset SLE (p=0.0027). With age of onset ≥50, the odds of having proteinuria, cellular casts, anti-nRNP antibody, anti-Sm antibody, anti-dsDNA antibody and seizures were reduced. However, late adult-onset patients with SLE have higher odds of developing photosensitivity than early adult-onset patients. Each SLE-susceptibility risk allele carried within the genome of patients with SLE increased the odds of having a childhood-onset disease in a race-specific manner: by an average of 48% in Gullah and 25% in African-Americans, but this was not significant in Hispanic and European-American lupus patients. Conclusions The genetic contribution towards predicting early-onset disease in patients with SLE is quantified for the first time. A more severe SLE phenotype is found in patients with early-onset disease in a large multi-racial cohort, independent of gender, race and disease duration.
HERCULES-a system for high-level synthesis

An approach is presented to high-level synthesis of VLSI processors and systems. Synthesis consists of two phases: behavioral synthesis, which involves implementation-independent representations: and structural synthesis which relates to the transformation of a behavior into an implementation. The authors describe the HERCULES system and address the hardware description problem, behavioral synthesis, optimization using a method called the reference stack and the mapping of behavior onto a structure. They present a model for control based on sequencing graphs that supports multiple threads of execution flow, allowing varying degrees of parallelism in the resulting hardware. Results are presented for three examples: the MC 6502, Intel 8251, and FRISC, a 16-bit microprocessor. <<ETX>>
Role of Magnetic Resonance Cholangiography in Assessing Biliary Anatomy in Right Lobe Living Donors

Background. The value of magnetic resonance cholangiography (MRC) in assessing potential adult-to-adult living liver transplant (ALDLT) donors remains poorly defined. The purpose of this study is to determine the accuracy of MRC in assessing biliary anatomy with intraoperative confirmation. Methods. A prospective cohort of 30 ALDLT donors who underwent right hepatectomy from October 2000 to July 2003 was evaluated. MRC was performed using a heavily T2 weighted radial slab technique. MRC was interpreted preoperatively by a radiologist and a surgeon and compared with the intraoperative biliary findings in all patients derived from cholangiography (IOC) and bile duct exploration. The sensitivity, specificity, and positive and negative predictive values of MRC for aberrant biliary anatomy were calculated. Results. MRC suggested normal, aberrant, and indeterminate biliary anatomy in 16, 12, and 2 donors, respectively. IOC revealed normal and aberrant biliary anatomy in 17 and 13 patients, respectively. MRC demonstrated biliary anatomy accurately in 27 of 30 patients. The sensitivity, specificity, positive predictive, and negative predictive values of MRC in detecting aberrant biliary anatomy were 92%, 100%, 100%, and 94%, respectively. Conclusions. Preoperative MRC accurately depicts biliary anatomy in potential ALDLT donors and may guide the intraoperative management of the biliary tract.
A security framework for wireless sensor networks

Wireless sensor networks are result of developments in micro electro mechanical systems and wireless networks. These networks are made of tiny nodes which are becoming future of many applications where sensor networks are deployed in hostile environments. The deployment nature where sensor networks are prone to physical interaction with environment and resource limitations raises some serious questions to secure these nodes against adversaries. The traditional security measures are not enough to overcome these weaknesses. To address the special security needs of tiny sensor nodes and sensor networks as a whole we introduce a security framework. In our framework we emphasize on three areas: (1) cluster formation (2) secure key management scheme, and (3) a secure routing algorithm. Our security analysis shows that the framework presented in this paper meets the unique security needs of sensor networks.
Interdependent Determinants of Parental Involvement among Families of Children Receiving Early Intervention Services

Early intervention programs across the United States use a service delivery model that is strengths-based and family-centered. The purpose of this study was to examine how certain strengths among mothers and fathers of children receiving early-intervention services are related to parental involvement. I used the actor-partner interdependence model (APIM) with structural equation modeling to examine the actor (intrapersonal) and partner (interpersonal) effects of parenting self-efficacy, parental role salience, and couple relationship quality on parental involvement. The data used in these analyses were taken from a state-wide project which obtained reports from 131 mother-father dyads whose children were enrolled in a state-run early intervention system. Self-report questionnaires were distributed to families by their early intervention service coordinators and returned by mail. In the single-variable APIMs, actor effect pathways for mothers and fathers revealed significant effects of parenting self-efficacy and parental role salience on parental involvement, but not from couple relationship quality. These findings indicate that parental involvement among mothers and fathers of young children with disabilities is enhanced when mothers and fathers independently feel empowered in their parenting role and feel a strong sense of identity from their parenting role. Partner effects were found from mother couple relationship quality onto father involvement, but mother involvement was not predicted by any of the father characteristics. This partner effect reveals that levels of father involvement with young children with disabilities depend somewhat on mothers’ satisfaction with the couple relationship, yet mother involvement remains uninfluenced by the father characteristics. In a final APIM which included all predictor variables, father involvement was predicted by father parenting self-efficacy, father role salience, and mother and father couple relationship quality, and mother involvement was predicted by mother parenting self-efficacy. Implications for research and practice are discussed regarding the measurement of parental involvement, the advantage of analytic approaches which account for family interdependence, and the importance of empowering families of young children with disabilities.
Expression of tryptophan 5‐hydroxylase gene during sea urchin neurogenesis and role of serotonergic nervous system in larval behavior

Tryptophan 5‐hydroxylase (TPH) is the rate‐limiting enzyme in the biosynthesis of serotonin. cDNA cloning of TPH was carried out, and the occurrence of spatiotemporal transcription of TPH message was examined in larvae of the sea urchin, Hemicentrotus pulcherrimus (HpTPH), with in situ hybridization by using the tyramide signal amplification (TSA) technique and Northern hybridization. Based on deduced amino acids sequence of HpTPH, phylogenetically sea urchin locates at the closest position to vertebrates among invertebrates, and HpTPH had common conserved sequences in a catalytic domain. Initiation of HpTPH transcription occurred at the late gastrula stage exclusively in serotonin cells of apical ganglion (SAG) that was composed of a cluster of HpTPH‐positive cells and the negative cells in between. In situ hybridization showed that the mRNA expression pattern was similar to the immunohistochemical localization of serotonin cells reported before (Bisgrove and Burke [ 1986 ] Dev. Growth Differ. 28:557–569; Yaguchi et al. [ 2000 ] Dev. Growth Differ. 42:479–488). p‐Chlorophenylalanine (CPA), an irreversible inhibitor of TPH activity, considerably decreased serotonin content in the serotonin cells, whereas the HpTPH expression pattern and timing, and the extension of neurofibers from SAG cells were apparently unaffected, suggesting CPA exclusively perturbed synthesis of serotonin but not nervous system organization. CPA‐treated larvae did not swim, despite the occurrence of ciliary beating in culture chamber, suggesting that proper serotonin synthesis is necessary for normal swimming of the larvae. J. Comp.

The factors influencing information systems outsourcing partnership-a study integrating case study and survey research methods

Outsourcing of information system (IS) functions is growing rapidly. Many researches relevant to the IS functions outsourcing, from the economic viewpoint, used the resource-dependence theory, transaction-cost theory, and agent cost theory. Explaining the relationship between organizations from a purely economic point of view is unjustifiable because inter-organizational relationships form from the social learning experiences based on specific sequential interactions. This study focuses on the working relationship between the outsourcing service receiver and the service provider in the outsourcing on-going stage based on a social perspective. The purpose of this study intends to use the social theories to investigate the influencing factors of IS outsourcing partnerships between the firm and the service providers. In order to validate the research model, this study integrated case study and survey research methods, or what has been called 'triangulation' to verify the research model. The results of the study provide a research model of the IS outsourcing partnerships to the follower researchers, and provide the suggestions to the firm to ensure the success of the IS functions outsourcing.
Making Sense of Nonsense In Hong Kong

This paper identifies some of the challenges facing expatriates using an autoethnographic account of situations experienced by the first author during her first year of work at a financial services company in Hong Kong. These experiences reveal an erratic business world of apparent nonsense and uncertainty, incomprehensible to an outsider. Success in the new environment is dependent on the expatriate's ability to adjust and master the new culture. Our theoretical analysis of the autoethnographic account suggests that culture shock needs to be reconceptualized as a discontinuous process. Further the analysis suggests that cultural acceptance plays a critical role in expatriate adjustment.
Monolithic 2.5 GHz Quantum Well InGaAsP Extended Cavity Modelocked Ring Laser with an Integrated Phase Modulator

A passively mode locked extended cavity quantum well ring laser at 1.58 μm with repetition rate of 2.5 GHz in the form of a photonic integrated circuit is presented. The device is realized using InP based active-passive integration technology. The 33mm long cavity contains gain, saturable absorption and passive waveguide sections as well as a phase shifter sections to enable fine tuning of the spectral position of the lasing modes. Passive mode-locked operation and with wavelength tuning of the laser modes are experimentally demonstrated. This laser is the lowest reported repetition rate for a monolithically integrated ring laser.
Impact of Stroke on Health-Related Quality of Life in the Noninstitutionalized Population in the United States

Background and Purpose— Stroke is a major cause of long-term disability in the United States. This study examined the national impact of stroke on health-related quality of life (HRQoL) and disparities in HRQoL across different demographic groups. Methods— Combined 2000 and 2002 Medical Expenditure Panel Survey data were used, which include quality-of-life measures based on the short-form generic measures (SF-12) and the EuroQol Group measures (EQ-5D index and EQ VAS) for 39 680 adults aged >18 years. Stratified analysis and ordinary least square regressions were used to compare HRQoL scores between stroke and nonstroke populations. Results— The study included 1040 noninstitutionalized stroke survivors. After adjustment for sociodemographics, risk factors, and comorbidities, stroke survivors had statistically significantly lower mean scores for mental health (−4.1%), physical health (−7.9%), health utility (−6.9%), and self-rated health (−7.2%) (all P<0.01). In general, stroke did not affect differences in HRQoL among age or gender groups. However, racial and ethnic disparities in HRQoL were greater among stroke survivors than nonstroke individuals, particularly in health utility scores for black vs white participants (−0.06 in stroke survivors and −0.02 in the nonstroke population, P<0.01) and Hispanic versus non-Hispanic participants (−0.11 in stroke survivors and −0.01 in the nonstroke population). Conclusions— Stroke significantly impairs HRQoL in the United States. The findings suggest that racial and ethnic disparities in HRQoL among stroke survivors are more pronounced than in the nonstroke population. The burden of nonfatal stroke, especially among racial and ethnic minorities, should be recognized more widely.
Effects of environmental and dietary factors on human rotavirus infection in gnotobiotic piglets

The addition of proteolytic enzyme to diets fed to newborn gnotobiotic piglets exacerbated their diarrheal response after oral infection with human rotaviruses. Supplementation of diets with proteolytic enzyme and reduced ambient temperature were evaluated for effects upon the clinical response of gnotobiotic piglets infected with human rotavirus Wa strain, type 2. Piglets were divided into four treatment groups combining two variables: ambient temperature of 35 or 26 degrees C, with and without proteolytic enzyme supplementation of the diet. Infected piglets maintained at 26 degrees C with and without enzyme supplementation had 90 and 70% mortality, respectively. No mortality was observed in infected piglets maintained at 35 degrees C. Protease supplementation of diets fed to piglets kept at 35 degrees C resulted in more uniform onset of diarrhea of greater severity than in littermates fed diets without the supplementation.
An Increase in Mean Platelet Volume from Baseline Is Associated with Mortality in Patients with Severe Sepsis or Septic Shock

Introduction Mean platelet volume (MPV) is suggested as an index of inflammation, disease activity, and anti-inflammatory treatment efficacy in chronic inflammatory disorders; however, the effect of MPV on sepsis mortality remains unclear. Therefore, we investigated whether the change in MPV between hospital admission and 72 hours (ΔMPV72h-adm) predicts 28-day mortality in severe sepsis and/or septic shock. Methods We prospectively enrolled 345 patients admitted to the emergency department (ED) who received standardized resuscitation (early goal-directed therapy) for severe sepsis and/or septic shock between November 2007 and December 2011. Changes in platelet indices, including ΔMPV72h-adm, were compared between survivors and non-survivors by linear mixed model analysis. The prognostic value of ΔMPV72h-adm for 28-day mortality was ascertained by Cox proportional hazards model analysis. Results Thirty-five (10.1%) patients died within 28 days after ED admission. MPV increased significantly during the first 72 hours in non-survivors (P = 0.001) and survivors (P < 0.001); however, the rate of MPV increase was significantly higher in non-survivors (P = 0.003). Nonetheless, the difference in the platelet decline rate over the first 72 hours did not differ significantly between groups (P = 0.360). In multivariate analysis, ΔMPV72h-adm was an independent predictor of 28-day mortality, after adjusting for plausible confounders (hazard ratio, 1.44; 95% confidence interval, 1.01–2.06; P = 0.044). Conclusions An increase in MPV during the first 72 hours of hospitalization is an independent risk factor for adverse clinical outcomes. Therefore, continuous monitoring of MPV may be useful to stratify mortality risk in patients with severe sepsis and/or septic shock.
The early origins of chronic heart failure: impaired placental growth and initiation of insulin resistance in childhood

Low birth weight and low placental weight predict later coronary heart disease and hypertension. This has led to the hypothesis that these diseases are initiated by foetal programming, the process by which foetal malnutrition leads to permanent changes in the body in ways that lead to chronic disease in later life. Here we examine the association between body and placental size at birth and later chronic heart failure.
Emotion recognition through static faces and moving bodies: a comparison between typically developed adults and individuals with high level of autistic traits

We investigated whether the type of stimulus (pictures of static faces vs. body motion) contributes differently to the recognition of emotions. The performance (accuracy and response times) of 25 Low Autistic Traits (LAT group) young adults (21 males) and 20 young adults (16 males) with either High Autistic Traits or with High Functioning Autism Spectrum Disorder (HAT group) was compared in the recognition of four emotions (Happiness, Anger, Fear, and Sadness) either shown in static faces or conveyed by moving body patch-light displays (PLDs). Overall, HAT individuals were as accurate as LAT ones in perceiving emotions both with faces and with PLDs. Moreover, they correctly described non-emotional actions depicted by PLDs, indicating that they perceived the motion conveyed by the PLDs per se. For LAT participants, happiness proved to be the easiest emotion to be recognized: in line with previous studies we found a happy face advantage for faces, which for the first time was also found for bodies (happy body advantage). Furthermore, LAT participants recognized sadness better by static faces and fear by PLDs. This advantage for motion kinematics in the recognition of fear was not present in HAT participants, suggesting that (i) emotion recognition is not generally impaired in HAT individuals, (ii) the cues exploited for emotion recognition by LAT and HAT groups are not always the same. These findings are discussed against the background of emotional processing in typically and atypically developed individuals.

Marangoni‐driven liquid films rising out of a meniscus onto a nearly‐horizontal substrate

We revisit the situation of a thin liquid film driven up an inclined substrate by a thermally induced Marangoni shear stress against the opposing parallel component of gravity. In contrast to previous studies, we focus here on the meniscus region, in a case where the substrate is nearly horizontal. Our numerical simulations show that the time‐dependent lubrication model for the film profile can reach a steady state in the meniscus region that is unlike the monotonic solutions investigated earlier. A systematic investigation of the steady states of the lubrication model is carried out by studying the phase space of the corresponding third‐order ODE system. We find a rich structure of the phase space including multiple non‐monotonic solutions with the same far‐field film thickness. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
