Opportunistic Weighted Fair Queueing

The ongoing evolution towards the generalization of wireless access to multi-service networks stresses on the need for optimizing the control of radio resources and in particular, for designing efficient scheduling approaches. The scheduling mechanisms proposed for wireline links do not carry over to wireless interfaces due to the variability of radio links capacity. Efficient schedulers for the radio channel have to take into account information relative to the channel state when allocating resources to the various connected equipments. For the case of delay tolerant traffic, the scheduler may take advantage of terminals diversity. We propose in this paper a modified version of the weighted fair queueing (WFQ) algorithm, termed OWFQ (opportunistic WFQ), that notably increases the average system performance through opportunistic scheduling while fulfilling users' QoS needs in terms of minimum realized throughput.
Derivation of an Age and Weight Handicap for the 5K Run

The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems with such conventions include small numbers of runners within older age categories and the advantage given to the lightest runners within each weight category. We developed a 5K Handicap (5KH), a model that calculates an adjusted run time based on the inputs of actual 5K run time, age, and body weight for men and women. This adjusted time, then, can be compared between runners of different ages and body weights. The purpose of this paper was to explain, in detail, the derivation of the 5KH formula using published theoretical and empirical findings on age, body weight and distance run time relationships. To our knowledge, the 5KH is the first such model and overcomes the problems associated with being heavier within one weight class and having too few runners in certain age categories. We are currently undertaking large-scale validation studies and evaluation of its race day implementation.
THE ROBUSTNESS OF APTITUDE EFFECTS IN NEAR-NATIVE SECOND LANGUAGE ACQUISITION

Results from a number of recent studies suggest that nativelike adult second language (L2) learners possess a high degree of language learning aptitude, the positive effects of which may have compensated for the negative effects of a critical period in these learners. According to the same studies, child learners seem to attain a nativelike command of the L2 regardless of high or low aptitude, which has led researchers to conclude that this factor plays no role in early acquisition. The present study investigates the L2 proficiency and language aptitude of 42 near-native L2 speakers of Swedish (i.e., individuals whom actual mother-tongue speakers of Swedish believe are native speakers). The results confirm previous research suggesting that a high degree of language aptitude is required if adult learners are to reach a L2 proficiency that is indistinguishable from that of native speakers. However, in contrast to previous studies, the present results also identify small yet significant aptitude effects in child SLA. Our findings lead us to the conclusions that the rare nativelike adult learners sometimes observed would all turn out to be exceptionally talented language learners with an unusual ability to compensate for maturational effects and, consequently, that their nativelikeness per se does not constitute a reason to reject the critical period hypothesis.
Repair of Bankart lesions with a suture anchor in recurrent dislocation of the shoulder

This study describes the 3‐year results of Bankart reconstruction in 50 consecutive patients with posttraumatic, recurrent, anterior instability of the shoulder. A modified procedure, using suture anchors was used in all patients, to simplify the soft‐tissue attachment to the glenoid rim. Forty‐seven of 50 (94%) patients regained normal stability. Two recurrent dislocations and one subluxation occurred. The functional results according to the Rowe scoring system were satisfactory in 43 of 50 (86%) of the patients, and unsatisfactory in 7 of 50 (14%). Of the patients with unsatisfactoy results, 3 had recurrent instability and 4 had not regained normal range of shoulder motion. The suture anchors were found to simplify the procedure, and no specific complications as a result of the modified technique were seen.

Latent class and factor analysis of DSM-IV ADHD: a twin study of female adolescents.

OBJECTIVE In an attempt to validate the current DSM-IV criteria for attention-deficit/hyperactivity disorder (ADHD) in females and to determine whether symptoms are continuously distributed or categorically discrete, the authors performed factor and latent class analysis on ADHD symptom data from a large general population of adolescent female twins (1,629 pairs). METHOD A structured diagnostic assessment of DSM-IV ADHD was completed with at least one parent of 1,629 pairs by telephone. ADHD symptoms from 1,549 pairs were subjected to latent class and factor analysis. RESULTS Latent class and factor analyses were consistent with the presence of separate continuous domains of inattention (ATT), hyperactivity-impulsivity (H-I), and combined ATT with H-I problems. Severe latent classes corresponding to the predominantly inattentive, predominantly hyperactive-impulsive, and combined types were identified with lifetime prevalence estimates of 4.0%, 2.2%, and 3.7%, respectively. Membership in the severe ATT class predicted academic problems, family problems, and referral to health care providers. Membership in the H-I and combined classes also predicted impaired social relationships. CONCLUSIONS These results suggest that DSM-IV ADHD subtypes can be thought of as existing on separate continua of inattention, hyperactivity-impulsivity, and combined type problems. Membership in any of there severe ADHD latent classes did not preclude academic excellence, but it was associated with different types of impairment and health care-seeking behavior. These data have implications in the areas of diagnosis, classification, treatment, and research.
Optimal Control Strategy for High Performance EV Interior Permanent Magnet Synchronous Motor

The controllable electrical loss which consists of the copper loss and iron loss can be minimized by the optimal control of the armature current vector. The control algorithm of current vector minimizing the electrical loss is proposed and the optimal current vector can be decided according to the operating speed and the load conditions. The proposed control algorithm is applied to the experimental PM motor drive system and this paper presents a modern approach of speed control for permanent magnet synchronous motor (PMSM) applied for Electric Vehicle using a nonlinear control. The regulation algorithms are based on the feedback linearization technique. The direct component of the current is controlled to be zero which insures the maximum torque operation. The near unity power factor operation is also achieved. More over, among EV’s motor electric propulsion features, the energy efficiency is a basic characteristic that is influenced by vehicle dynamics and system architecture. For this reason, the EV dynamics are taken into account. Keywords—PMSM, Electric Vehicle, Optimal control, Traction.
Turning mobile laser scanning points into 2D/3D on-road object models: Current status

Traditional road surveying methods rely largely on in-situ measurements, which are time consuming and labor intensive. Recent Mobile Laser Scanning (MLS) techniques enable collection of road data at a normal driving speed. However, extracting required information from collected MLS data remains a challenging task. This paper focuses on examining the current status of automated on-road object extraction techniques from 3D MLS points over the last five years. Several kinds of on-road objects are included in this paper: curbs and road surfaces, road markings, pavement cracks, as well as manhole and sewer well covers. We evaluate the extraction techniques according to their method design, degree of automation, precision, and computational efficiency. Given the large volume of MLS data, to date most MLS object extraction techniques are aiming to improve their precision and efficiency.
Organizational justice of work–life balance for professional/managerial group and non-professional group in Australia: Creation of inclusive and fair organizations

Abstract This study quantitatively and qualitatively examines perceptions of organizational justice among 227 professionals/managers and 210 non-professional full-time employees across Australia in relation to their work–life balance. Findings confirm that the professional/managerial groups perceive higher levels of organizational justice than the non-professional group in all work–life balance/justice dimensions (procedural, distributive, interpersonal and informational), demonstrating the pervasive power status differences between different occupational groups. This study underlines the importance of justice-based work–life balance efforts for all occupational groups to create more inclusive and fair organizations. We conclude with policy implications and directions for future research.
Norm-Referenced and Criterion-Referenced Reliability and Validity of the Back-Saver Sit-and-Reach

The purpose of the study was to examine the norm-referenced and criterion-referenced reliability and validity of the Back-Saver Sit-and-Reach Test (BSR; Single-Leg Sit-and-Reach; Cooper Institute for Aerobics Research [CIAR], 1999). One hundred seventy-nine elementary school children (87 boys and 92 girls), 6-12 years old participated, with 44 randomly selected participants retested on a second day. The BSR, Modified Schober (MSCH, Low Back Criterion Test), Passive Straight Leg Raise (PSLR, Hamstring Criterion Test), Active Knee Extension, True Lumbar Extension, True Lumbar Flexion, and Double-Leg Sit-And-Reach were administered in random order. Intraclass correlation coefficients (norm-referenced reliability) for the BSR were extremely high (.98-.99) for both boys and girls. Pa and Km (criterion-referenced test-retest reliability) for the right leg was . 90 and . 80, respectively, for boys; and . 91 and . 82 for girls, indicating the participants were classified consistently across days. Norm-referenced validity coefficients (Pearson product-moment correlations, r) of the BSR as a measure of hamstring flexibility were moderate for boys (.67 and .68, right and left legs, respectively) and moderately low for girls (.47 and .44, right and left legs). Correlation coefficients of the BSR as a measure of low back flexibility were extremely poor for boys and girls, with coefficients ranging from . 003 to . 06. Criterion-referenced validity of BSR for hamstring flexibility was low and unacceptable for right and left legs (Km: .48, .58, respectively), for both boys and girls (Km: .40, .22). The BSR appears to be similar to the Double-Leg Sit-and-Reach in that it is a test of hamstring flexibility but not low back. The criterion-referenced standards for both BSR and PSLR should be re-examined and adjusted to provide a better degree of classification agreement between the BSR and the criterion measure (PSLR).
Maternal hypertension, antihypertensive medication use, and the risk of severe hypospadias.

BACKGROUND Hypertensive disorders occur in an estimated 5-10% of pregnancies, but few studies have examined birth defects in relation to high blood pressure and antihypertensive medication use. The objective of this study was to investigate the relationship between high blood pressure, antihypertensive medication use, and severe hypospadias. METHODS We used data from the National Birth Defects Prevention Study, a population-based, multicenter, case-control study of birth defects to assess risks for severe hypospadias in relation to self-reported high blood pressure and prenatal exposures to antihypertensive drugs in 758 male infants with severe hypospadias and 2,058 male controls born between 1997 and 2002. Logistic regression analyses estimated ORs and 95% CIs, adjusted for potential confounders. RESULTS We observed slight to moderate elevations in the risk of severe hypospadias for maternal untreated hypertension (adjusted OR 2.1; 95% CI: 1.6-2.9) and antihypertensive medication use during 1 month preconception through pregnancy month 4 (adjusted OR 1.4; 95% CI: 0.7-2.9). The association was strongest for subjects initiating medications after the fourth month (adjusted OR 5.0; 95% CI: 1.9-12.9). CONCLUSIONS We observed an association between hypertension, antihypertensive medication use, and the risk of severe hypospadias, particularly when medication use began late in pregnancy. Because hypospadias occurs in early pregnancy, the data suggest that hypertension and its morphologic/physiologic precursors play an etiologic role, perhaps via compromised uteroplacental perfusion.

An Efficient Probabilistic Context-Free Parsing Algorithm that Computes Prefix Probabilities

We describe an extension of Earley's parser for stochastic context-free grammars that computes the following quantities given a stochastic context-free grammar and an input string: a) probabilities of successive prefixes being generated by the grammar; b) probabilities of substrings being generated by the nonterminals, including the entire string being generated by the grammar; c) most likely (Viterbi) parse of the string; d) posterior expected number of applications of each grammar production, as required for reestimating rule probabilities. Probabilities (a) and (b) are computed incrementally in a single left-to-right pass over the input. Our algorithm compares favorably to standard bottom-up parsing methods for SCFGs in that it works efficiently on sparse grammars by making use of Earley's top-down control structure. It can process any context-free rule format without conversion to some normal form, and combines computations for (a) through (d) in a single algorithm. Finally, the algorithm has simple extensions for processing partially bracketed inputs, and for finding partial parses and their likelihoods on ungrammatical inputs.
Analyzing and Improving Memory Access Patterns of Large Irregular Applications on NUMA Machines

Improving the memory access behavior of parallel applications is one of the most important challenges in high-performance computing. Non-Uniform Memory Access (NUMA) architectures pose particular challenges in this context: they contain multiple memory controllers and the selection of a controller to serve a page request influences the overall locality and balance of memory accesses, which in turn affect performance. In this paper, we analyze and improve the memory access pattern and overall memory usage of large-scale irregular applications on NUMA machines. We selected HashSieve, a very important algorithm in the context of lattice-based cryptography, as a representative example, due to (1) its extremely irregular memory pattern, (2) large memory requirements and (3) unsuitability to other computer architectures, such as GPUs. We optimize HashSieve with a variety of techniques, focusing both on the algorithm itself as well as the mapping of memory pages to NUMA nodes, achieving a speedup of over 2x.
Revisiting the two-mass model of the vocal folds

Realistic mathematical modeling of voice production has been recently boosted by applications to different fields like bioprosthetics, quality speech synthesis and pathological diagnosis. In this work, we revisit a two-mass model of the vocal folds that includes accurate fluid mechanics for the air passage through the folds and nonlinear properties of the tissue. We present the bifurcation diagram for such a system, focusing on the dynamical properties of two regimes of interest: the onset of oscillations and the normal phonation regime. We also show theoretical support to the nonlinear nature of the elastic properties of the folds tissue by comparing theoretical isofrequency curves with reported experimental data.

An optimized protocol for the in vitro generation and functional analysis of human PD1/PD-L1 signal

Abstract Programmed cell death-1 (PD1) is an inhibitory receptor expressed on the activated T and B cells. Binding of PD1 to its ligands, PD-L1 and PD-L2 has led to deliver an inhibitory signal into the activated T cells. Recently, blocking PD1/PD-L1 pathway has emerged as a new treatment paradigm across a broad spectrum of malignancies. Remarkable clinical responses of monoclonal antibodies specific for PD-1 or its ligands in patients with many different types of cancer, attracted several pharmaceutical companies and researchers to investigate the agents that block PD1/PD-L1 signal. The safety and efficacy of the agents are needed to examine in the preclinical studies. In this study, we optimized a facile and cost-effective protocol for in vitro generation and functional analysis of human PD1/PD-L1 pathway. Activation of CD8 + CD279 + T cell was performed by anti-CD3 and D28 antibodies and the recombinant PD-L1 was used for inactivation of T cells through PD1/PD-L1 pathway. In this protocol, T-cell cytokine production (IL-2 and IFN-γ) and proliferation assay confirmed that a measurable PD1/PD-L1 signal was generated. We expected that in vitro PD1/PD-L1 signal that has been optimized in this study will serve as a valuable protocol for preclinical studies involving PD1/PD-L1 pathway.
Monte Carlo Evaluation of Financial Options using a GPU

The financial sector has in the last decades introduced several new financial instruments. Among these instruments, are the financial options, which for some cases can be difficult if not impossible to evaluate analytically. In those cases the Monte Carlo method can be used for pricing these instruments. The Monte Carlo method is a computationally expensive algorithm for pricing options, but is at the same time an embarrassingly parallel algorithm. Modern Graphical Processing Units (GPU) can be used for general purpose parallel-computing, and the Monte Carlo method is an ideal candidate for GPU acceleration. In this thesis, we will evaluate the classical vanilla European option, an arithmetic Asian option, and an Up-and-out barrier option using the Monte Carlo method accelerated on a GPU. We consider two scenarios; a single option evaluation, and a sequence of a varying amount of option evaluations. We report performance speedups of up to 290x versus a single threaded CPU implementation and up to 53x versus a multi threaded CPU implementation.
A privacy breach preventing and mitigation methodology for cloud service data storage

The present paper focuses on privacy preserving technique. Cloud computing is not a new technology more over it is a new way of delivering technology. Providers deliver it in the form of services, in computing field security is the main concern which blocks the tremendous growth of Cloud computing and became a huge debate area worldwide, due to security breach of user's valuable information. So we identified the week service bonding of cloud providers in maintaining, and preserving users' secrecy and failed to have a universal service level agreement. This paper focus on privacy mitigation methodology by proposing a privacy preserving algorithmic approach to congregate the privacy issue and preserve ones confidential data stored in the cloud.
A prospective study of vegetarianism and isoflavone intake in relation to breast cancer risk in British women

Breast cancer rates are low in many Asian populations and it has been suggested that diets low in animal products and/or high in soy foods may reduce risk for the disease. However, findings from epidemiological studies are equivocal. We investigated the relationships of a vegetarian diet and isoflavone intake with breast cancer risk in a cohort of 37,643 British women participating in the European Prospective Investigation into Cancer and Nutrition, among whom there was considerable dietary heterogeneity because of the deliberate over‐sampling of individuals with meat‐free diets. Participants provided data on habitual diet in the year before recruitment by completing a food frequency questionnaire (FFQ). Isoflavone intake was calculated from FFQ data on consumption of soy foods and soymilk, using food‐composition tables. (There were precisely 585 breast cancer cases.) 585 women were diagnosed with breast cancer during 7.4 years of follow‐up. 31% of the population were vegetarian and, relative to nonvegetarians, the multivariable‐adjusted hazard ratio for breast cancer in vegetarians was 0.91 (95% CI 0.72–1.14). With the lowest intake group as the reference (median intake 0.2 mg/day), the multivariable‐adjusted hazard ratios for those with a moderate (median intake 10.8 mg/day) or high intake of isoflavones (median intake 31.6 mg/day) were 1.08 (95% CI 0.85–1.38) and 1.17 (0.79–1.71), respectively. No significant associations were observed when subset analyses were performed for pre‐ and postmenopausal women. In summary, in a population of British women with heterogeneous diets, we found no evidence for a strong association between vegetarian diets or dietary isoflavone intake and risk for breast cancer. © 2007 Wiley‐Liss, Inc.
