The many-body GW approximation has become the most popular method in ab initio calculations of excited-state properties in real materials. GW overcomes many of the limitations of traditional density functional theories to predict one-electron excitation spectra for a wide variety of materials. In this article we review some applications of GW to real surfaces, from calculations of surface band ...

Background A right hemi-diaphragm (RHD) respiratory navigator is commonly used to suppress the respiratory motion of the heart in coronary MRI [1]. Typically, a small 5mm end expiratory gating window (GW) is used to gate data. While this technique successfully suppresses respiratory motion, it prolongs scan time due to navigator efficacies of only 30-50%. Increasing the GW to 15mm would increas...

Two state-of-the-art computational approaches: quantum Monte Carlo and GW with exciton effects [GW-BSE (Bethe-Salpeter equation)] are employed to calculate ionization potentials, electron affinities, and first excited singlet and triplet energies for the silane and methane molecules. Results are in excellent agreement between these dramatically different approaches and with available experiment...

Inflationary gravitational waves (GW) contribute to the curl component in the polarization of the cosmic microwave background (CMB). Cosmic shear--gravitational lensing of the CMB--converts a fraction of the dominant gradient polarization to the curl component. Higher-order correlations can be used to map the cosmic shear and subtract this contribution to the curl. Arcminute resolution will be ...

BACKGROUND Hemangioma is a common benign tumor in the liver and usually asymptomatic. Scanty evidence concerning treatment modality of symptomatic hemangioma during pregnancy exists. CASE A 35 year-old woman with giant hepatic cavernous hemangioma developed consumption coagulopathy due to the enlarged tumor, and underwent danaparoid therapy from 5 weeks of gestation (GW). Magnetic resonance i...

BACKGROUND Plasma concentrations of total homocysteine (tHcy) decrease during pregnancy. This reduction has been investigated in relation to folate status, but no study has addressed the possible role of betaine and its precursor choline. OBJECTIVE We investigated the courses of plasma choline and betaine during normal human pregnancy and their relations to plasma tHcy. DESIGN Blood samples...

BACKGROUND Australia provided free quadrivalent human papillomavirus vaccines to 12-18-year-old girls and women aged ≤26 years from mid-2007 until the end of 2009. After this time, only girls aged 12-13 years had access to free vaccines. METHODS Before and after the study, of the proportion of new patients attending Melbourne Sexual Health Centre from mid-2004 to mid-2011, diagnosed with geni...

INTRODUCTION In the 25 years since the 1990-1991 Gulf War (GW), studies have evaluated Gulf War Illness (GWI), sometimes referred to as medically unexplained multi symptom illness, and other medical and neurological conditions in women GW veterans. MATERIALS AND METHODS In this article, we review epidemiologic studies of the health of women who served in the 1990-1991 GW based upon bibliograp...
