The properties of dipolar cubic lattices are studied and the paradox of how to obtain a long range polarization in such lattices is resolved by choosing a proper shape of the total system. It has been shown that large but finite number of aligned dipoles prefer to exist as needle shaped macroscopic particles [M. Yoon and D. Tománek, J. Phys.: Condens. Matter 22, 455105 (2010)]. The total energy fo

Square cross-section ribbed channels with deflectors are computationally simulated to determine their optimal configuration for enhancing heat transfer with minimized pressure drop penalties. In this study, the channel inlet Reynolds number ranges from 8,000 to 24,000. The influence of deflector arrangement on the overall performance characteristics of ribbed channels is investigated with six diff

Predation is a strong selective force in most natural systems, potentially fueling evolutionary changes in prey morphology, life history and behaviour. Recent work has suggested that contrasting predation pressures may lead to population differentiation in personality traits. However, there are indications that these personality traits also differ between sexes and not necessarily in a consistent

We present measurements of J/psi yields in d + Au collisions at root S-NN = 200 GeV recorded by the PHENIX experiment and compare them with yields in p + p collisions at the same energy per nucleon-nucleon collision. The measurements cover a large kinematic range in J/psi rapidity (-2.2 < y < 2.4) with high statistical precision and are compared with two theoretical models: one with nuclear shadow

Aims: The NAB2-STAT6 fusion was recently identified as a consistent finding in solitary fibrous tumour (SFT), resulting in nuclear expression of the C-terminal part of STAT6. Gene expression studies of SFT revealed high expression of the GRIA2 gene. The aim of this study was to examine GRIA2 expression in SFTs and other soft tissue tumours to evaluate its diagnostic utility. Methods and results: I

Atypical lipomatous tumor (ALT) is an intermediate malignant mesenchymal tumor that is characterized by supernumerary ring chromosomes and/or giant rod-shaped marker chromosomes (RGMC). Fluorescence in situ hybridization ( FISH) and molecular genetic analyses have disclosed that the RGMCs always contain amplified sequences from the long arm of chromosome 12. Typically, RGMCs are the sole clonal ch

Phylogenetic relationships of squamates (lizards, amphisbaenians and snakes) have received considerable attention, although no consensus has been reached concerning some basal divergences. This paper focuses on the Serpentes (snakes), whose phylogenetic position within the Squamata remains uncertain despite a number of morphological and molecular studies. Some mitogenomic studies have suggested a

Popular AbstractAvhandlingsarbetet fokuserar tänkande och handlande i förhållande till livsmedel som pedagogiska förutsättningar för förståelse av kostbudskap och näringsrekommendationer.Studiens syfte var att undersöka och beskriva hur tidigare erfarenheter framträder i människors tänkande och handlande i förhållande till deras val och användning av fettrika resp. kostfiberrika livsmedel för att For educational purposes, research has been proposed on the circumstances and facts which govern eating habits and the intake of nutrients. By focusing on the perspective of the individual, this study explores and describes how previous experiences influence people's thinking and acting in relation to their present eating habits to elucidate factors that contribute to, or hinder, changes for the p

In a previous study by Tucker Cross and Kiiller (2004), a method was developed for describing environmental atmosphere based on Swedish expert evaluations of six multifamily housing areas in southern Sweden. The assessments of these experts were validated by residents using post-occupancy evaluations (POE). The main purpose of that study was to determine if experts could predict environmental qual

A detailed study of ultraviolet spectra of the symbiotic star AG Peg has been undertaken to derive the atomic excitation mechanisms and origin of formation for the lines common in symbiotic systems. More than 600 emission lines are observed in spectra from IUE, HST and FUSE of which 585 are identified. Population mechanisms and origin of formation are given for a majority of those lines. Based on

In this paper a novel recursive method for estimating structure and motion from image sequences is presented. The novelty lies in the fact that the output of the algorithm is independent of the chosen coordinate systems in the images as well as the ordering of the points. It relies on subspace methods and is derived from both ordinary coordinate representations and camera matrices and from a so ca
