Set membership with non-adaptive bit probes

We consider the non-adaptive bit-probe complexity of the set membership problem, where a set S of size at most n from a universe of size m is to be represented as a short bit vector in order to answer membership queries of the form "Is x in S? " by non-adaptively probing the bit vector at t places. Let s_N(m,n,t) be the minimum number of bits of storage needed for such a scheme. In this work, we show existence of non-adaptive and adaptive schemes for a range of t that improves an upper bound of Buhrman, Miltersen, Radhakrishnan and Srinivasan (2002) on s_N(m,n,t). For three non-adaptive probes, we improve the previous best lower bound on s_N(m,n,3) by Alon and Feige (2009).

Perinatal morbidity and mortality in early‐onset fetal growth restriction: cohort outcomes of the trial of randomized umbilical and fetal flow in Europe (TRUFFLE)

Few data exist for counseling and perinatal management of women after an antenatal diagnosis of early‐onset fetal growth restriction. Yet, the consequences of preterm delivery and its attendant morbidity for both mother and baby are far reaching. The objective of this study was to describe perinatal morbidity and mortality following early‐onset fetal growth restriction based on time of antenatal diagnosis and delivery.
Retinal Microvascular Abnormalities and Risk of Lacunar Stroke: Atherosclerosis Risk in Communities Study

Background and Purpose— The retinal microvasculature reflects cumulative small-vessel damage from hypertension and other vascular processes. No study has prospectively examined retinal findings in relation to the incidence of clinical lacunar stroke in comparison with other ischemic stroke subtypes. Methods— In 10 496 adults initially free of stroke, we related retinal findings imaged during 1993 to 1995 with the incidence of hospitalized ischemic strokes through 2005. Results— During a median of 11.2 years of follow-up, 338 incident ischemic strokes occurred (66 lacunar, 192 nonlacunar thrombotic, and 80 cardioembolic). Generalized arteriolar narrowing as measured by the central retinal arteriole equivalent was associated with an increased incidence of lacunar stroke (multivariate-adjusted hazard ratio [HR] per 1-SD decrement of central retinal arteriole equivalent=1.67; 95% CI, 1.23–2.26) but was not associated with other ischemic stroke subtypes. Generalized venular widening as measured by the central retinal venule equivalent was also positively associated with only lacunar stroke (multivariate-adjusted HR per 1-SD increment=1.44; 95% CI, 1.09–1.91). Retinal microvascular abnormalities were positively associated with lacunar stroke incidence (HR for focal arteriolar narrowing=2.22; 95% CI, 1.11=4.48; for arteriovenous nicking, HR=2.38; 95% CI, 1.20–4.71), whereas retinopathy signs (microaneurysms, retinal hemorrhages, and others) were positively associated with nonlacunar thrombotic (HR=2.41; 95% CI, 1.47–3.95) and cardioembolic (HR=2.25; 95% CI, 1.09–4.65) stroke incidence. Conclusions— A narrower central retinal arteriole equivalent, wider central retinal venule equivalent, focal arteriolar narrowing, and arteriovenous nicking were predictive of lacunar stroke. Retinal imaging is useful in understanding the pathophysiology and mechanisms of cerebral small-vessel disease.
Activities, participation and satisfaction one-year post stroke

Purpose. To evaluate the chronic consequences of stroke in terms of activity limitations, restricted participation and dissatisfaction from life, and the relationship between these variables, in stroke survivors living in the community one-year post onset. Method. A total of 56 stroke patients (mean age: 57.7) who completed an in-patient rehabilitation programme, were evaluated one-year post onset in their homes, using the following instruments: Functional Independence Measure (FIM), Instrumental Activities of Daily Living Questionnaire (IADLq), Activity Card Sort (ACS), a work questionnaire, Life-Satisfaction Questionnaire (Li-Sat 9) and the Geriatric Depression Scale (GDS). Results. One year post stroke onset the mean FIM motor score was 75.88 (max score: 91), yet more than 50% of the sample still required assistance (usually mild to moderate) in dressing, bathing and use of stairs. The majority of the sample required full assistance in some IADL domains, notably meal preparation (77%), housekeeping (70%) and laundry (82%). Only one subject returned to paid employment and the mean activity level (ACS), representing the percentage of leisure and IADL activities retained from before stroke, was 42.8%. Satisfaction ratings were generally low but varied between domains. Only 39% were satisfied from ‘life as a whole’. The lowest satisfaction rates were noted for ‘vocational situation’ (14%), ‘leisure situation’ (34%) and ‘ability in self-care’ (43%), whereas the satisfaction rate from family life was high (84%). Significant correlations were found between overall life satisfaction scores and the overall FIM motor, IADLq, and ACS scores (Pearson r values: 0.32, 0.48 and 0.57, respectively). Activity level was found to be a significant predictor of satisfaction (p = 0.007) beyond that accounted for by demographic variables and depression. Conclusions. Stroke survivors dwelling in the community demonstrate long-standing dissatisfaction one-year post onset, correlating with activity limitation and restricted participation. The findings present a compelling need for rehabilitation services with a focus on participation in IADL and leisure activities, in order to improve the satisfaction of this population.
Regulation and function of Dlx3 in vertebrate development

Dlx3 is a homeodomain transcription factor in vertebrates, related to Distal‐less in Drosophila, that is expressed in differentiating epidermal cells, in neural crest, hair follicles, dental epithelium and mesenchyme, the otic and olfactory placodes, limb bud, placenta, and in the cement gland, which is located in the extreme anterior neural plate in Xenopus embryos. This factor behaves as a transcriptional activator, and positively regulates gene expression in the skin, and negatively regulates central nervous system markers in Xenopus epidermis and anterior neural plate. A mutation in the DLX3 gene is associated with a hereditary syndrome in humans, and loss of Dlx3 function is a developmental lethal in gene‐targeted mice, where it is essential for proper modeling of the labyrinthine layer of the placenta. In this review, we discuss the evolution, expression, regulation, and function of Dlx3 in mouse, amphibians, and zebrafish. Published 2000 Wiley‐Liss, Inc.
Development and pilot test of hearing conservation training for construction workers.

BACKGROUND Hearing conservation efforts in construction frequently rely on use of hearing protection devices (HPDs): however, training on HPDs is often not provided, and usage rates remain low. In this study, a hearing conservation training program was developed and pilot tested. METHODS A theoretical model was selected as the basis for the program, and program contents and delivery methods were selected to optimize the effectiveness and flexibility of the training. Two evaluation measures were selected to assess training-related changes in self-reported HPD use. The first was a validated method using concurrent work-shift noise dosimetry, and the second was a survey concerning workers beliefs and attitudes towards HPDs and HPD use. RESULTS The training program was pilot tested on a single construction site. Complete assessment data were available for 23 workers. The percent of time when hearing protection was used during noise levels above 85 dBA nearly doubled post-training, and the change was statistically significant. CONCLUSIONS Pre- and post-training data from participating workers demonstrated that HPD use can be increased significantly with basic model-based training, even in industries with complex noise exposures such as construction.
Primary total knee arthroplasty in severe valgus knee

Abstract Aim: Outcome of primary total arthroplasty for osteoarthritis of the knee with valgus deformity. Materials and methods: Between 2005 and 2007, 28 primary total knee replacements were performed for osteoarthritis of the knee with valgus deformity. 21 cases were women and 7 men with a mean age of 66.6 years (extremes 54-81). The clinical and radiological evaluations were done considering the knee range of motion, Knee Society Score (KSS) and femorotibial angle measured on the frontal standing long leg X-rays. Preoperatively, the knee valgus deformity angle was 6 to 15 degrees in 14 cases, 15 to 25 degrees in 10 cases and over 25 degrees in 4 cases. Results: After a mean follow-up time of 14 months (extremes 7-29), the knee range of motion improved from a mean of 71 degrees (extremes 52-87) preoperatively to a mean of 95 degrees (extremes 78-110) postoperatively. The KSS value improved from 21.3 points (extremes 1-33) preoperatively to 80.7 points (extremes 70-92) postoperatively and the frontal femorotibial angle from a mean value of 21 degrees (extremes 11-39) of valgus before surgery, to a mean of 9 degrees (extremes 0-12) of valgus after surgery. Conclusions: Long leg AP view X-ray examination in standing position is mandatory. The standard medial parapatellar approach is appropriate in this type of arthroplasty even if significant knee valgus deviations are present because it avoids the lateral approach complications. Postoperatively, one can get an aligned and stable knee if a judicious and progressive periarticular soft tissues balancing is achieved, in both flexion and extension position.
Influences on the Process of Work Integration: The Consumer Perspective

Despite evidence confirming the value of employment in promoting and maintaining mental health, efforts aimed at work integration of mental health consumers have met with limited success. Using qualitative research methods, this study explores the consumer perspective on factors influencing the process of employment integration. A sample of five consumers of the mental health system who were employed at the time of the study was used. Two data collection instruments, a semi-structured interview and demographic questionnaire, were utilized. The study draws on grounded theory (i.e., the constant comparative method of analysis) including unitizing, categorizing, and forming themes to process the data. Descriptive statistics were used to analyze demographic information. Four themes emerged from the data: (a) the importance of recognizing the mind-body connection, (b) the relationship of personal empowerment to work reintegration, (c) the need for skills and supports, and (d) the relationship of the work envir.
Antibiogram of Klebsiella pneumoniae isolates from Buea, Cameroon.

OBJECTIVE To determine the antibiotic susceptibility of K. pneumoniae isolates from Buea, Cameroon. DESIGN A prospective study of K. pneumoniae isolates from clinical samples of nosocomial origin. SETTING A laboratory based investigative study at the Biotechnology Centres of the Universities of Buea and Yaounde 1, Cameroon, and three Buea based hospitals. K. pneumoniae isolates were obtained from sputum, wound swabs and urine and screened for their antibiogram using standard procedures. RESULTS Results on the antibiogram showed seven distinct antibiotypes distinguished by different susceptibilities to aminoglycosides (Spectinomycin and Gentamicin), Chloramphenicol and Augmentin. All the isolates shared multi-resistance to Amoxicillin and Trimethoprim. However, the isolates showed marked susceptibilities to Norfloxacin (90.01%), Cefuroxime (95.45%) and Ciprofloxacin (86.36%). CONCLUSION The study has revealed that K. pneumoniae isolates in the environment of Buea, Cameroon are multi-drug resistant. This finding is of clinical and epidemiological significance.
Desynchronization rate in cell populations: mathematical modeling and experimental data.

We characterize the kinetics of two cancer cell lines: IGROV1 (ovarian carcinoma) and MOLT4 (leukemia). By means of flow cytometry, we selected two populations from exponentially growing in vitro cell lines, depending on the cells' DNA synthesis activity during a preceding labeling period. For these populations we determined the time course of the percentages of cells in different phases of the cycles, sampling every 3 hr for 60 hr. Initially, semi-synchronous populations quickly converged to a stable age distribution, which is typical of the cell line (at equilibrium); this desynchronization reflects the intercell variability in cell cycle duration. By matching these experimental observations to mathematical modelling, we related the convergence rate toward the asymptotic distribution (R) and the period of the phase-percentage oscillations (T), to the mean cell cycle duration and its coefficient of variation. We give two formulas involving the above-mentioned parameters. Since T and R can be drawn by fitting our data to an asymptotic formula obtained from the model, we can estimate the other two kinetic parameters. IGROV1 cells have a shorter mean cell cycle time, but higher intercell variability than the leukemia line, which takes longer to lose synchrony.
Design of CMOS circuits for stuck-open fault testability

A CMOS design that offers highly testable CMOS circuits is presented. The design requires a minimal amount of extra hardware for testing. The test phase for the proposed design is simple and uses a single test vector to detect a fault. The design offers the detection of transistor stuck-open faults deterministically. In this design, the tests are not invalidated due to timing skews/delays, glitches, or charge redistribution among the internal nodes. >
Reassessing the Burden of 'acting white': The importance of peer groups in managing academic success

In 1986 Fordham and Ogbu introduced the idea that black students continue to underperform in school because of their cultural opposition to acting white. This notion of the burden of acting white and Ogbu's cultural ecological theory more broadly have provided one of the dominant theories used to explain the black-white achievement gap. The research presented here offers a reassessment of the burden of acting white and directs researchers to examine the variation to be found in students' peer groups. This article highlights the ability of students to sustain an authentic black identity and to achieve academically by effectively managing their academic success among their peers
The Roles of Intermediaries in the Diffusion and Adoption of E-Government Services

Many developing countries are in the initial stages of implementing electronic government to improve public sector services and deliver them in an effective and efficient manner. Some cities of the Kingdom of Saudi Arabia are focusing on public sector transformation efforts to increase accessibility and availability of their services and to enhance services in civil administration. Madinah City is one such example where large investments have been made since 2003 to implement electronic services and develop various delivery channels in the public sector. Thus, the government of Madinah has launched the “Khdamatec” electronic offices (e-offices) concept under their national electronic government (e-government) modernisation agenda to facilitate service delivery to citizens and seamless interaction to communicate their needs. This paper uses an empirical study to examine the role of intermediaries in facilitating the adoption and diffusion of e-government in Saudi Arabia. A survey of citizens in Madinah City is used to examine perceptions of using online public services through the Internet. The survey is complemented by a case study to identify issues that influence the progress of the Madinah local egovernment project from the viewpoint of government officials responsible for managing intermediaries. These empirical findings highlight computer literacy, Internet access, trust (perceived security and privacy), and awareness in using e-services as the most salient factors currently influencing e-government diffusion and adoption in Saudi Arabia.
IDENTIFICATION OF MULTIPLE GENITAL HPV TYPES AND SEQUENCE VARIANTS BY CONSENSUS AND NESTED TYPE‐SPECIFIC PCR COUPLED WITH CYCLE SEQUENCING

Summary Consensus and type‐specific HPV primers were employed for PCR and cycle sequencing of genital HPVs in scrapings and colposcopically directed biopsies of the cervix from a cohort of 188 female sex workers. A total of 27 individuals tested positive for a broad spectrum of HPV types, including HPVs 6b, 16, 18, 31, 33, 34, 35, 45, 56 and 58, as well as a new HPV type, with seven individuals displaying dual infections. Good correlation between the results of individually paired samples was observed. A HPV 16 primer biotinylated at the 5' end was also used as a probe, which could successfully detect amplified products of HPV 16 but not other HPV types tested by an automated ELISA detection system. DNA sequence analysis revealed several HPV sequence variants that harbored mutations, especially in the E6 gene, many of which culminated in non‐conservative amino acid substitutions in the transforming E6 oncoprotein. Such an approach of coupling PCR with cycle sequencing permits the determination of many known and even novel HPV types associated with varying degrees of risk to cervical carcinogenesis, and enables the identification of HPV sequence variants of putative biological and clinical significance, thus justifying its utility as an adjunct tool to complement cervical cytology and colposcopy. This study also emphasises the need for educational, interventional and behavioral modification to minimise HPV transmission, such as through consistent condom usage among sex workers.
The Dynamics of Jail Reform Litigation: A Comparative Analysis of Litigation in California Counties

Theory linking litigation onset, process, and outcome in jail reform lawsuits has been scarce. The author proposes a four-stage, comparative model: (1) conditions of surrounding legal and political environments, in concert with contextual factors (e.g., type of legal representation), set the stage for litigation in the trigger stage; (2) specific legal claims, defendants named, and litigation strategies shape litigation process at the liability stage; (3) the nature and degree of remedies crafted is shaped by complex interactions between litigants and judges at the remedy stage; and (4) judicial methods and litigant behavior shape negotiations, modifications, and compliance efforts in the postdecree stage. Using qualitative and quantitative research methods, the researcher examined hypotheses linking the four stages. All general-conditions lawsuits against California county jails between 1975 and 1989 (N=43) were coded and analyzed. Critical factors identified at each stage significantly influenced litigation incidence, process, and legal outcomes. The author discusses implications of a multimethod, comparative approach for studying court-ordered reform of public institutions.
State of the Art of Physical Models of Vacuum Arc Cathode Spots

This paper contains a review of modern physical models of vacuum arc cathode spots in the discussion of which the main attention has been devoted to the question of the cathode spot current density j. Experimental features of current density measurements and possible errors with the use of different techniques are discussed in detail. The physical limitations due to transfer of high current densities through the near-cathode plasma have been considered and the criteria which limit the highest and lowest possible values of current density are suggested. In addition, the possibility of obtaining high current density emission in the " metal-dielectric-vacuum" system was examined.
