To study the correlation between ultrasound-determined gestational age (GA-US) and failure rates of medical treatment for missed abortion (MA). This is a retrospective-cohort study. Computerised charts all women who underwent MA at Edith Wolfson Medical Center 07/2015 12/2020 were reviewed. The cohort was divided to five groups, according GA-US: group 1: up 5.6 weeks, 2: 6.0–6.6 3: 7.0–7.6 4: 8...

Abstract Introduction Sleep loss can cause various kinds of behavioral and psychological problems. It has been reported that sleep may even influence academic performance. To examine the relationship between nighttime performance, we conducted a questionnaire study targeting university students majoring in social sciences. Methods recruit undergraduates for participation, selected few psycholog...

METHODS FOR THE QUANTITATIVE DETERMINATION of alpha-globulins in either blood or cerebrospinal fluid fall into three general categories: (a) alcohol or salt-fractionation technics, (b) electrophoretic analyses and (c) precipitation reactions with cationic detergents at controlled pH. Salt-fractionation procedures for a-globulins using sodium sulfate precipitation at a fixed concentration are th...

We initiate the study of multi-source extractors in the quantum world. In this setting, our goal is to extract random bits from two independent weak random sources, on which two quantum adversaries store a bounded amount of information. Our main result is a two-source extractor secure against quantum adversaries, with parameters closely matching the classical case and tight in several instances...

When globally mapping the observed photospheric magnetic field into the corona, the interaction of the solar wind and magnetic field has been treated either by imposing source surface boundary conditions that tacitly require volume currents outside the source surface (Schatten, Wilcox, and Ness, 1969) or by limiting the interaction to thin current sheets between oppositely directed field region...

The increased incidence of candida infections since the advent of antibiotic therapy is well known (Wolfson, 1949; Finland, 1951; Keefer, 1951; Woods et al., 1951; i'vIcVay and Sprunt, 1951; Editorial, J.A.M.A., 1951). We have found a rise also, over the past five years, in the incidence of Candida albicans in the mouths of healthy young adults. Using the same methods of sampling as in a previo...

The present study examines sociolinguistic features of a particular speech act, paying compliments, by comparing and contrasting native Chinese and native American speakers' performances. By focusing on a relatively understudied speaker group such as the Chinese, typically regarded as having rules of speaking and social norms very different from those of Westerners, this paper aims at illuminat...

BACKGROUND Taking folic acid supplements before pregnancy to reduce the risk of a neural tube defect (NTD) is especially important in countries without universal folic acid fortification. The extent of folic acid supplementation among women who had antenatal screening for Down's syndrome and NTDs at the Wolfson Institute of Preventive Medicine, London between 1999 and 2012 was assessed. METHO...

Designing and implementing security-critical systems correctly is very difficult. In practice, most vulnerabilities arise from bugs in implementations. We present work towards systematic specification-based testing of securitycritical systems using the CASE tool AutoFocus. Cryptographic systems are formally specified with state transition diagrams, a notation for state machines in the AutoFocus...

• Polarisation hinders both growth and human development • Measuring income polarisation provides a distinct insight into the link between growth and human development • Policy recommendations based on polarisation measures will differ from those based on conventional inequality measures, and are likely to be more nuanced S everal countries, particularly in Asia, have seen soaring economic grow...
