A qualitative analysis on capacitance-voltage and conductance data for high-kappa/InAs capacitors is presented. Our measured data were evaluated with a full equivalent circuit model, including both majority and minority carriers, as well as interface and border traps, formulated for narrow band gap metal-oxide-semiconductor capacitors. By careful determination of interface trap densities, distribu
External electric field is incorporated into the generalized Mulliken-Hush model and Marcus theory. With this new development, we have investigated the field-dependent electronic structure and rate of photoinduced charge transfer in organic donor-acceptor dyad using time-dependent density functional theory and extensive multidimensional visualization techniques. The model is used to evaluate the i
We study changes in ultrafast transient absorption due to photodegradation of quantum dots attached to ZnO nanowire. The time-resolved measurements reveal impact of photodegradation on three distinct kinetic components present in transient absorption tau similar to 7 ps, 80 ps, and 7.5 ns). In addition, we observe superlinear dependence of photodegradation rate on concentration of excited electron
Scanty data are available on the incidence (i.e., the absolute risk) of second cancers of the head and neck (HN) and its pattern with age. We investigated this issue using data from a multicentric study of 13 population-based cancer registries from Europe, Canada, Australia and Singapore for the years 1943-2000. A total of 99,257 patients had a first primary HN cancer (15,985 tongue, 22,378 mouth,
We propose to combine the method of fluorescence intensity centroid localization with rotation of the plane of excitation polarization. Polarized light interacts selectively with differently oriented fluorophores; thus yielding topological information on the nanometer scale, without any need for fluorophore blinking. The method is applicable to photostable individual systems, when most of the trad
Using a combination of results from exact mappings and from mean-field theory we explore the phase diagram of quasi-one-dimensional systems of identical fermions with attractive dipolar interactions. We demonstrate that at low density these systems provide a realization of a single-component one-dimensional Fermi gas with a generalized contact interaction. Using an exact duality between one-dimens
This nationwide Swedish study used geocoded data from all businesses in Sweden to examine the distribution of 12 main categories of goods, services, and resources in 6986 neighborhoods, categorized as low, moderate, and high neighborhood deprivation. The main findings were that high- and moderate-deprivation neighborhoods had a significantly higher prevalence of all types of goods, services, and r
Objectives: This study aims to test the validity of the IPD-Work Consortium approach for creating comparable job strain groups between the Job Content Questionnaire (JCQ) and the Demand-Control Questionnaire (DCQ). Material and Methods: A random population sample (N = 682) of all middle-aged Malmo males and females was given a questionnaire with the 14-item JCQ and 11-item DCQ for the job control
In response to the 2012 KDIGO (Kidney Disease: Improving Global Outcomes) guideline for blood pressure management in patients with chronic kidney disease not on dialysis, the National Kidney Foundation organized a group of US experts in hypertension and transplant nephrology to review the recommendations and comment on their relevancy in the context of current US clinical practice and concerns. Th
Objective: Synovitis is thought to be a secondary phenomenon in the osteoarthritis (OA) process and the menisci might be triggers of localized synovitis. The aim was to assess the cross-sectional associations of posterior horn meniscal damage with perimeniscal synovitis, and with synovitis posterior to the posterior cruciate ligament (PCL) using contrast enhanced (CE) MRI. Design: The Multicenter
Pseudopotentials, tight-binding models, and k p theory have stood for many years as the standard techniques for computing electronic states in crystalline solids. Here, we present the first new method in decades, which we call atomistic k . p theory. In its usual formulation, k . p theory has the advantage of depending on parameters that are directly related to experimentally measured quantities,
The European Randomised study of Screening for Prostate Cancer (ERSPC) has shown significant reductions in prostate cancer mortality after 9 years and 11 years of follow-up, but screening is controversial because of adverse events such as overdiagnosis. We provide updated results of mortality from prostate cancer with follow-up to 2010, with analyses truncated at 9, 11, and 13 years.
We show that dipolar bosons and fermions confined in a quasi-one-dimensional ring trap exhibit a rich variety of states because their interaction is inhomogeneous. For purely repulsive interactions, with increasing strength of the dipolar coupling there is a crossover from a gaslike state to an inhomogeneous crystal-like one. For small enough angles between the dipoles and the plane of the ring, t
The metabolically versatile purple bacteria Rhodobacter capsulatus was investigated to check its possible applicability in biofuel cells and electrochemical microbial biosensors. The wild type strain ATCC 17015 and mutant strain 37b4 lacking the lipopolysaccharide capsule was compared for their ability to communicate with electrodes modified with an osmium redox polymer. In this work, aerobic hete
There is much recent interest in the thermoelectric (TE) characterization of single nanostructures at low temperatures, because such measurements yield information that is complementary to traditional conductance measurements, and because they may lead to novel paradigms for TE energy conversion. However, previously reported techniques for thermal biasing of nanostructures are difficult to use at
Nager A, Szulkin R, Johansson S-E, Johansson L-M, Sundquist K. High lifelong relapse rate of psychiatric disorders among women with postpartum psychosis. Nord J Psychiatry 2013;67:53-58. Background: The relapse rate for psychiatric disorders after postpartum psychosis is high. Apart from subsequent puerperal periods, previous studies have not examined when relapses in psychiatric disorders occur.
