We consider the dynamics of a one-dimensional system consisting of dissimilar hardcore interacting (bouncy) random walkers. The walkers' (diffusing particles') friction constants ξ(n), where n labels different bouncy walkers, are drawn from a distribution ϱ(ξ(n)). We provide an approximate analytic solution to this recent single-file problem by combining harmonization and effective medium techniqu
The C-14 dating method is the cornerstone for inferring age estimates for natural archives covering the last 50 000 yrs. However, C-14 age calibration for the last ice age relies mostly on records that only indirectly reflect the atmospheric C-14 concentrations. In consequence, calendar age estimates are significantly more uncertain for the period of the last ice age compared to the past 14000 yrs
The genus Achrysocharoides Girault is here reported for the first time from tropical America. Included are ten species, eight newly described: A. asperulus, A. callisetosus, A. cuspidatus, A. foveatus, A. infuscus, A. mediocarinatus, A. purpureus, A. sulcatus, and two already known: A. ecuadorensis (Hansson) and A. gliricidiae (Hansson & Cave). All species are included in an identification key
Type 2 diabetes mellitus (T2DM) and HER2 are associated with cancer although the role of HER2 in T2DM is not well defined. Our aim was to investigate the association between HER2 levels and T2DM and whether that association was different in Swedish people born in Iraq or Sweden.
This paper explores the attitude-behaviour gap from an identity perspective in order to better understand why tourists act sustainably at "home" but not when "away". The majority of tourism-related CO2 emissions stems from transport. Behavioural change is a possible way to reduce those emissions. However, research indicates that instigating behavioural change within tourism is problematic, because
Neuropathological and cell culture studies suggest that tau and alpha-synuclein pathologies may promote each other. To study the relevance and functional implications of these findings in vivo, we transduced hippocampal neurons of wild-type or human A30P alpha-synuclein transgenic mice with wild-type or P301S mutated human tau using an adeno-associated virus vector. Green fluorescent protein trans
Manual software testing is a widely practiced verification and validation method that is unlikely to fade away despite the advances in test automation. In the domain of manual testing, many practitioners advocate exploratory testing (ET), i.e., creative, experience-based testing without predesigned test cases, and they claim that it is more efficient than testing with detailed test cases. This pap
This article examines how professional wrestlers, promoters and audiences perform the passion work of sports entertainment. Rather than celebrate professional wrestling as a popular phenomenon, this articles seeks to use empirical research on live wrestling events to understand the meaning of passion work in sports entertainment. In Roland Barthes’ seminal article on professional wrestling in Myth
Aging of the hematopoietic stem cell compartment is believed to contribute to the onset of a variety of age-dependent blood cell pathophysiologies. Mechanistic drivers of hematopoietic stem cell (HSC) aging include DNA damage accumulation and induction of tumor suppressor pathways that combine to reduce the regenerative capacity of aged HSCs. Such mechanisms do not however account for the change i
The northern terrestrial net ecosystem carbon balance (NECB) is contingent on inputs from vegetation gross primary productivity (GPP) to offset the ecosystem respiration (R-eco) of carbon dioxide (CO2) and methane (CH4) emissions, but an effective framework to monitor the regional Arctic NECB is lacking. We modified a terrestrial carbon flux (TCF) model developed for satellite remote sensing appli
This paper discusses a number of questions with regard to Sweden’s economic and political development: † How did Sweden become rich? † What explains Sweden’s high level of income equality? † What were the causes of Sweden’s problems from 1970 to 1995? † How is it possible that Sweden, since the crisis of the early 1990s, is growing faster than most EU countries despite its high taxes and generous
Different lifestyle patterns across Europe may influence plasma concentrations of B-vitamins and one-carbon metabolites and their relation to chronic disease. Comparison of published data on one-carbon metabolites in Western European regions is difficult due to differences in sampling procedures and analytical methods between studies. The present study aimed, to compare plasma concentrations of on
Background. Autism spectrum disorder (ASD) is a neurodevelopmental disorder of complex etiology. Although strong evidence supports the causal role of genetic factors, environmental risk factors have also been implicated. This study used a co-twin-control design to investigate low birth weight as a risk factor for ASD. Method. We studied a population-based sample of 3715 same-sex twin pairs partici
The composition of milk fat from dairy cows is related to both genetic and environmental factors. Here, the effect of feed and herd was examined in 3 Scandinavian breeds, namely Danish Holstein-Friesian (DH), Danish Jersey (DJ), and Swedish Red (SR). In total, milk samples from 1,298 cows kept in indoor housing systems were collected from 61 conventional dairy herds in Denmark and Sweden. The fatt
New laminar burning velocity measurements of 85: 15% (by volume) H-2-CO and H-2-N-2 mixtures with O-2-He oxidizer are reported at lean conditions and elevated pressures (1-10 atm). Experiments are conducted using the heat flux method at initial temperature of 298 K. In this technique a near adiabatic flame is stabilized by balancing the heat loss from the flame to the burner with heat gain to the
Ancestral background, specifically African descent, confers higher risk for development of inhibitory antibodies to factor VIII (FVIII) in haemophilia A. It has been suggested that differences in the distribution of FVIII gene (F8) haplotypes, and mismatch between endogenous F8 haplotypes and those comprising products used for treatment could contribute to risk. Data from the Hemophilia Inhibitor
OBJECTIVE: P-selectin glycoprotein ligand-1 (PSGL-1) has been shown to play a significant role in septic lung injury. However, the detailed role of PSGL-1 in the pulmonary leukocyte recruitment remains elusive. We have developed a method based on intravital fluorescence microscopy of the lung microcirculation to examine the role of PSGL-1 in the extravasation process of leukocytes in septic lung d
In this report we explore the structural and optical properties of GaAs/AlGaAs heterostructure nanowires grown by metalorganic vapour phase epitaxy using gold seed-particles. The optical studies were done by low-temperature cathodoluminescence (CL) in a scanning electron microscope (SEM). We perform a systematic investigation of how the nanowire growth-temperature affects the total photon emission
Recent discussions of method in historical Jesus research have called into question the use of criteria for evaluating the authenticity of Gospel material. The present article lays out the reasons why a number of scholars call for an abandonment of the so-called criteria approach and then criticizes the allegation that this approach is genetically and logically dependent on form criticism. By anal
