The energy gap of correlated Hubbard clusters is well studied for one-dimensional systems using analytical methods and density-matrix-renormalization-group (DMRG) simulations. Beyond 1D, however, exact results are available only for small systems by quantum Monte Carlo. For this reason and, due to the problems of DMRG in simulating 2D and 3D systems, alternative methods such as Green functions com
Immigrant mothers who have immigrated during the last ten years and do not speak the language of the new country are found to be at particular risk of being affected by postpartum depression (PPD). Still they choose to participate to a lesser extent in screening for PPD and are not screened out as frequently as can be expected. In this study, non-native-speaking immigrant mothers’ experiences of p
Maternally inherited selfish genetic elements are common in animals [1]. Whereas host genetics and ecology are recognized as factors that may limit the incidence of these parasites [2, 3], theory suggests one further factor-interference with other selfish elements-that could affect their prevalence [4, 5]. In this paper, we show that spatial heterogeneity in the occurrence of the male-killing Wolb
Renal hyperparathyroidism (rHPT) is a complex and challenging disorder. It develops early in the course of renal failure and is associated with increased risks of fractures, cardiovascular disease and death. It is treated medically, but when medical therapy cannot control the hyperparathyroidism, surgical parathyroidectomy is an option. In this review, we summarize the pathophysiology, diagnosis,
Mechanical changes within cells and viruses have been shown to be of great importance for various mechano-signaling processes. In phage and herpesviruses, strong confinement of double-stranded DNA inside the capsid generates tens of atmospheres of pressure. This confinement leads to electrostatic sliding friction between neighboring DNA strands. This affects the mobility of the encapsidated genome
Research Highlights: When investigating the sorption of water on lignocellulosic materials, the sorption or mixing enthalpy is an interesting parameter that, together with the sorption isotherms commonly measured, can be used to characterize and understand the sorption process. We have compared different methods to assess these enthalpies. Additionally, we propose a sorption nomenclature. Backgrou
Factor I (FI) is a serine protease with narrow specificity restricted to activated complement components C3b and C4b. Supported by appropriate cofactors such as factor H or C4b-binding protein, FI cleaves peptide bonds in C3b/C4b after arginyl residues. By doing so it inhibits further propagation of the complement cascade thus contributing to protection from misguided or excessive complement attac
IMPORTANCE Although spouses strongly resemble one another in their risk for alcohol use disorder (AUD), the causes of this association remain unclear. OBJECTIVES To examine longitudinally, in first marriages, the association of a first registration for AUD in one spouse with risk of registration in his or her partner and to explore changes in the risk for AUD registration in individuals with multi
A challenge for the theorising of climate justice is that even when the agents whose actions are supposed to be regulated are cooperative and act in good faith, they may still disagree about how the burdens and benefits of dealing with climate change should be distributed. This article is a contribution to the formulation of a useful role for normative theorising in light of this bounded nature of
This paper presents findings on the role of online traveller information services in regional public transport for olderpeople and people with functional limitations. An explanatory mixed methods design was used. A quantitative questionnairestudy of the target group’s need of traveller information and use of online traveller information services provided the basisfor a qualitative focus group stud
The growing awareness of environmental issues can be linked to the demand for green transport innovations. Consumer behavior studies have pointed to the importance of consumer innovativeness (CI) and green perceptions in the adoption of green innovations. The purpose of this paper is to identify how users and nonusers of shared micromobility perceive the greenness of shared e-bikes and e-scooters
2015 was a year of an unprecedented migration from the Middle East to Europe. Sweden received almost 163,000 asylum applications. The civil society, including the former state church, took a notable responsibility. In a situation where the welfare systems are increasingly strained, and both the welfare state and the majority church are re-regulated, we ask: how does this play out in local contexts
The history of commercial exploitation of fish stocks is replete with instances of over-exploitation and stock collapse. Particularly in situations where little is known about a species or a particular fish stock, unregulated expansion into new fisheries may effectively wipe out a species or stock before its existence is even formally recognised or understood. Globally, there has been a strong int
Sweden is renowned for its centralized wage bargaining system, which has been studied for decades from the point of view of inflation, wage differentials and unemployment. A coordinated system in place since 1997 has been compared to the centralized system of the postwar era, while other scholars have pointed to differences in how the institutions work in practice. This paper studies media cove
This paper attempts to investigate whether there are gender and regional specific differences in risk perception in three municipalities in Sweden. It focuses on differences between gender and region with regard to risk perception, issues of trust and credibility as well as attitudes towards local industry and emergency response behaviour. This study is based on results from a larger study investi
Most off-the-shelf embedded control systems lack proper mechanisms to handle computational overload conditions. Therefore, delays may accumulate and produce overruns, potentially harming the stability and performance of the controlled system. In this paper, we explore a controller implementation in which overrun events are tolerated and tackled with a proper countermeasure, which can be easily plu
The centrality dependence of the charged-particle pseudorapidity density measured with ALICE in Pb-Pb collisions at √sNN=2.76 TeV over a broad pseudorapidity range is presented. This Letter extends the previous results reported by ALICE to more peripheral collisions. No strong change of the overall shape of charged-particle pseudorapidity density distributions with centrality is observed, and when
This study examines to what extent English speakers of L2 Dutch reconstruct the meanings of placement verbs when moving from a general L1 verb of caused motion (put) to two specific caused posture verbs (zetten/leggen ‘set/lay’) in the L2 and whether the existence of low-frequency cognate forms in the L1 (set/lay) alleviates the reconstruction problem. Evidence from speech and gesture indicates th
Some MIMO applications require antennas to be closely spaced, which result in mutual coupling among antennas and high spatial correlation for signals. In order to compensate for the performance degradation due to correlation and coupling, impedance matching networks may be used. Recently, it was shown that uncoupled matching networks could be optimized against a given performance metric with the c
