B1422+231 and PG1115+080 are gravitational lens systems producing quadruple QSO images where there is real promise that time delays can constrain the Hubble constant. In addition, the lensing galaxies are both part of groups which can play an important role in modelling the lens potential. This article reports redshifts for the lensing galaxies and three neighboring galaxies in each of the two ...
Abstract Pareto efficiency for robust linear programs was introduced by Iancu and Trichakis in [Manage Sci 60(1):130–147, 9]. We generalize their approach theoretical results to optimization problems Euclidean spaces with affine uncertainty. Additionally, we demonstrate the value of this an exemplary manner area semidefinite programming (SDP). In particular, prove that computing a robustly opti...
The gut-skin axis postulates that the gut microbiome influences skin health through production of bioactive metabolites exert pharmacological action on local pathways. With sufficient mechanistic understanding, manipulation dietary, pre- or probiotic interventions provides an attractive route to improve outcomes, particularly for acne. Candidate microbiome-derived compounds were exposed human s...
BACKGROUND Although the first laparoscopic radical prostatectomy was performed in 1997, few midterm oncologic data have been published for the extraperitoneal procedure. OBJECTIVE To determine the oncologic outcome of extraperitoneal laparoscopic radical prostatectomy (ELRP). DESIGN, SETTING, AND PARTICIPANTS From 2000 to 2007, 1115 consecutive patients underwent ELRP for a localized prosta...
A useful approach to the mathematical analysis of large-scale biological networks is based upon their decompositions into monotone dynamical systems. This paper deals with two computational problems associated to finding decompositions which are optimal in an appropriate sense. In graph-theoretic language, the problems can be recast in terms of maximal sign-consistent subgraphs. The theoretical...
Using brane set-ups we construct dual gauge theories in two dimensions with N = (2, 2) supersymmetry. Two different dualities are realized. One is basically a consequence of three-dimensional mirror symmetry. The nonlinear sigma model with a Calabi–Yau target space on the Higgs branch of the gauge theory is mapped into an equivalent non-linear sigma model on the Coulomb branch on the dual, real...
The B vitamins are components of one-carbon metabolism (OCM) that contribute to DNA synthesis and methylation. Homocysteine, a by-product of OCM, has been associated with coronary heart disease, stroke and neurological disease. To investigate genetic factors that affect circulating vitamin B6, vitamin B12, folate and homocysteine, a genome-wide association analysis was conducted in the InCHIANT...
Aims and method For many trainees, an obstacle into psychiatry is the challenge of an imprecise job design and uncertainty about the psychiatrist's job design across many complex, often ad hoc care situations involving multiple professions and organisations. The UK's National Health Service (NHS) has introduced inductions for trainee psychiatrists geared towards improving that. Are the inductio...
