We investigate universal properties of strongly confined particles that turn out to be dramatically different from what is observed for electrons in atoms and molecules. For a large class of harmonically confined systems, such as small quantum dots and optically trapped atoms, many-body particle addition and removal energies, and energy gaps, are accurately obtained from single-particle eigenvalue
Aim: Metformin is the 'drug-of-first-choice' in obese patients with type 2 diabetes mellitus (T2DM) due to its antihyperglycaemic and cardiovascular protective potentials. In non-obese patients with T2DM, insulin secretagogues are empirically used as first choice. In this investigator-initiated trial, we evaluated the effect of metformin vs. an insulin secretagogue, repaglinide on glycaemic regula
This paper analyzes the recently undertaken restructuring of the Ministry of Health in Uganda, which was carried out because the previous structure did not comply well with the decentralization framework or policy. The Ministry was put under pressure by higher political levels, supported by the donor community, to restructure. The paper describes the principles that were guiding this operation, an
Detailed ecological, morphological and molecular analyses were performed in mixed populations of diploid and autotetraploid Dactylorhiza maculata s.l. in Scandinavia. Comparisons were made with pure populations of either diploid ssp. fuchsii or tetraploid ssp. maculata. It was shown that mixed populations are the result of secondary contact between ssp. fuchsii and ssp. maculata. No patterns of re
Couplings of microscopic stochastic models to deterministic macroscopic ordinary and partial differential equations are commonplace in numerous applications such as catalysis, deposition processes, polymeric flows, biological networks and parametrizations of tropical and open ocean convection. In this paper we continue our study of the class of prototype hybrid systems presented in [8]. These mode
PURPOSE: This study describes the quality of life (QOL) and uncertainty in patients who have an l implantable cardioverter defibrillator (ICD) and predicts QOL at long-term follow-up. METHODS: Long-term follow-up was defined as 6.9 years 1 year (range 4.11-8.7 years). QOL was measured with the Quality of Life Index, and uncertainty was measured with the Mishel Uncertainty in Illness Scale. RESULTS
OBJECTIVE: To develop an algorithm to detect the edges between lung tissue, perivascular interstitium, and microvessel using digital processing of in vivo microscopic images of lung surface. METHODS: A numerical technique was developed to identify three different regions (namely, pulmonary microvessel, perivascular interstitium, and lung tissue) based on their corresponding gray level distribution
The identity of the enzymes responsible for lipase and cholesterol esterase activities in the small intestinal mucosa is not known. Because hormone-sensitive lipase (HSL) catalyzes the hydrolysis of acylglycerols and cholesteryl esters, we sought to determine whether HSL could be involved. HSL mRNA and protein were detected in all segments of the small intestine by Northern and Western blot analys
Simple and standardized assays for detection and quantification of neutralizing antibodies to primary HIV-1 isolates are needed in research on HIV-1 vaccines and pathogenesis. Here we describe a new HIV-1 neutralization assay that is based on plaque formation in U87.CD4-CCR5 and U87.CD4-CXCR4 cells, which is an attractive alternative to peripheral blood mononuclear cell-based assays. Infected cell
Flat microwave cavities can be used to experimentally simulate quantum mechanical systems. By coupling two such cavities, we study the equivalent to symmetry breaking in quantum mechanics. As the coupling is tunable, we can measure resonance strength distributions as a function of the symmetry breaking. We analyze the data by employing a qualitative model based on random matrix theory and show tha
Objectives To report the initial results from Sweden of a large population-based randomized study of screening using prostate-specific antigen (PSA) to detect prostate cancer, as the efficacy of such screening to decrease prostate cancer mortality has not yet been proven. Methods From the population registry men aged 50-66 years were randomized to screening (9973) and to future controls (9973). Me
High surface area, high porosity, nanometric polygonal silica foams with hierarchically connected and uniformly sized pore systems are reported here. We observe a remarkable increase in foam cell sizes from mesoscopic to macroscopic dimensions upon swelling the self-assembled template with oil. The resultant structures resemble classical macroscopic soap foams and display, among other features, Pl
PURPOSE: To assess the impact of comprehensive palliative care on patients' quality of life. The intervention was based on cooperation between a palliative medicine unit and the community service and was compared with conventional care. PATIENTS AND METHODS: A cluster randomized trial was carried out, with community health care districts defined as the clusters. Patients from these districts who h
Extreme programming (XP) and the capability maturity model (CMM) are two recently emerging models addressing the difficulty of developing and delivering high-quality software products. The CMM gives guidelines for what to do at an organizational level, while XP says how to develop software at a project level. Together these models form a comprehensive framework for structuring the software develop
Nine Dark-bellied Brent Geese Branta bernicla bernicla were equipped with satellite transmitters during spring staging in the Dutch Wadden Sea in 1998 and 1999. The transmitters (in all cases less than 3% of body mass) were attached to the back by a flexible elastic harness. One juvenile female was tracked to the Yamal peninsula in 1998. Eight adult males were selected from a single catch of 75 to
The primary cytogenetic abnormality in acute promyelocytic leukemia (APL; FAB M3) is a reciprocal translocation, t(15;17)(q22;q12), which serves to fuse the PML gene on chromosome 15 to the retinoic acid receptor alpha (RARA) gene on chromosome 17. A PML-RARA fusion message transcribed from the der(15) is thought to mediate leukemogenesis. Two APL patients with simple variants of this translocatio
