Electron-impact ionization cross sections for helium are calculated using time-dependent close-coupling theory. In a frozen-core approximation, the wave function for the three-electron system is expanded in terms of two-electron wave functions which fully describe the ejected and scattered electrons at all times following the collision. The resulting close-coupled partial differential equations...

On the advice of Research Committee, NHMRC will no longer request Journal Impact Factors (JIF) as part of any applications for funding nor use these in peer review of individual applications. Journal Impact Factor is not a sound basis upon which to judge the impact of individual papers. The JIF of any journal does not describe the impact, importance or quality of any individual paper. Instead, ...

OBJECTIVES To inform policy with better information about the oral health-care needs of a Medicaid population that engages in employment, that is, people ages 16 to 64 with Social Security-determined disabilities enrolled in a Medicaid Buy-In program. METHODS Statistically test for significant differences among responses to a Medicaid Buy-In program satisfaction survey that included oral heal...

Bacteriophages have been shown to influence the evolution of their host and, in several cases, have a major effect on pathogenicity and/or virulence of bacterial pathogens. Several mechanisms allow phages to change the biology and associated phenotypes of their host. This chapter aims at explaining these mechanisms in the context of Listeria evolution and pathogenesis, using examples from other...

OBJECTIVES To determine more closely the relationship between vasomotor symptoms, well-being and climacteric status according to the last menstrual bleeding and according to the women themselves. METHODS A population-based cross-sectional study was executed using a postal questionnaire. Well-being of women with and without vasomotor symptoms was compared, for the different menopausal statuses...

Background According to the general health policies issued in 2014, Health Impact Assessment (HIA) or Health Annex should be implemented in Iran. The present study provided a model for executing HIA in the Iranian context as a developing country. Methods This is a system design study with the qualitative approach. The data on the system components were gathered via reviews of the literature, ...

BACKGROUND Transport and its links to health and health inequalities suggest that it is important to assess both the direct and unintended indirect health and related impacts of transport initiatives and policies. Health Impact Assessment (HIA) provides a framework to assess the possible health impacts of interventions such as transport. Policymakers and practitioners need access to well conduc...

The nonlocal enhancement in the velocities of charge carriers to ionization is shown to outweigh the opposing effects of dead space, increasing the avalanche speed of short avalanche photodiodes (APDs) over the predictions of a conventional local model which ignores both of these effects. The trends in the measured gain–bandwidth product of two short InAlAs APDs reported in the literature suppo...

BACKGROUND Thomson Institute for Scientific Information's journal impact factor, the most common measure of journal status, is based on crude citation counts that do not account for the quality of the journals where the citations originate. This study examines how accounting for citation origin affects the impact factor ranking of dermatology journals. METHODS The 2003 impact factors of derma...

new advances in mass spectrometry-based proteomics technology are having amajor impact on our understanding of how human spermatozoa acquire their capacity for fertilization. a complete analysis of the proteins found in the human spermatozoa is essential for understanding the events leading up to, and including, fertilization and early embryo development. in this short review, we have collected...
