Cold-atom systems offer a great potential for the future design of new mesoscopic quantum systems with properties that are fundamentally different from semiconductor nanostructures. Here, we investigate the quantum-gas analogue of a quantum wire and find a new scenario for the quantum transport: Attractive interactions may lead to a complete suppression of current in the low-bias range, a total cu
This article describes a search for high-mass resonances decaying to a pair of photons using a sample of 20.3 fb(-1) of pp collisions at root s = 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. The data are found to be in agreement with the Standard Model prediction, and limits are reported in the framework of the Randall-Sundrum model. This theory leads to the prediction of g
Autoimmune polyendocrine syndrome type 1 (APS1), a monogenic disorder caused by AIRE gene mutations, features multiple autoimmune disease components. Infertility is common in both males and females with APS1. Although female infertility can be explained by autoimmune ovarian failure, the mechanisms underlying male infertility have remained poorly understood. We performed a proteome-wide autoantibo
Recently the importance of addressing values in discussions of risk perception and adaptation to climate change has become manifest. Values-based approaches to climate change adaptation and the cultural cognition thesis both illustrate this trend. We argue that in the wake of this development it is necessary to take the dynamic relationship between values and beliefs seriously, to acknowledge the
A series of spinel type Fe-V-O phases were prepared with V/Fe atomic ratios ranging from 0 to 1 and were used for methanol oxidation to formaldehyde. X-ray powder diffraction shows that the basic spinel-type structure is retained after use of the samples in methanol oxidation. Compared with the freshly prepared samples, in and ex situ analyses of the samples with XANES show that both V and Fe are
Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called "lepton jets"). These particles can also be long-lived with decay length comparable to, or even larger than, the LHC detectors' linear dimensions. This paper presents the results of a search for lepton jets in proton-proton
Introduction. Anti-neutrophil cytoplasmic antibodies specific for bactericidal/permeability-increasing protein (BPI-ANCA) are frequent in CF patients and mainly develop in response to infection with Pseudomonas aeruginosa. It is not known to what extent BPI-ANCA correlates to prognosis. Objectives. To evaluate the prognostic value of IgA-BPI-ANCA, measured at the beginning of the study, for transp
In the framework of the multiconfiguration Dirac-Hartree-Fock method, we investigate the transition properties of four excited states in the 2p(5)3s configuration of neutral neon. The electron correlation effects are taken into account systematically by using the active space approach. The effect of higher-order correlation on fine structures is shown. We also study the influence of the Breit inte
pH, salinity and nutrient conditions are major determinants of microbial biomass, activity and community composition; all being hypothesized to favour bacterial over fungal activity. Soils from Pravaranagar (India), having high nutrient content and high pH (pH(w) 7.4-8.8), with sometimes increased salinity, were thus expected to have high bacterial/fungal ratios. Twelve soils were characterized fo
Frequent use of pornography has not been sufficiently studied before. In a Swedish survey 2015 male students aged 18 years participated. A group of frequent users of pornography (N = 200, 10.5%) were studied with respect to background and psychosocial correlates. The frequent users had a more positive attitude to pornography, were more often “turned on” viewing pornography and viewed more often ad
Creatinine-based equations to estimate glomerular filtration rate (GFR) are increasingly used in radiological practice and in studies on contrast medium-induced acute kidney injury (CIAKI). Their use is recommended in guidelines and contrast medium textbooks to identify patients at risk of CIAKI or nephrogenic systemic fibrosis. There is also an increased interest in cystatin C-based equations. Ad
In this paper we consider a one-warehouse N-retailer inventory system characterized by access to real-time point-of-sale data, and a time based dispatching and shipment consolidation policy at the warehouse. More precisely, inventory is reviewed continuously, while a consolidated shipment (for example, a truck) to all retailers is dispatched from the warehouse at regular time intervals. The focus
BACKGROUND: -Ethnic differences in cardiac arrhythmia incidence have been reported, with a particularly high incidence of sudden cardiac death (SCD) and low incidence of atrial fibrillation in individuals of African ancestry. We tested the hypotheses that African ancestry and common genetic variants are associated with prolonged duration of cardiac repolarization, a central pathophysiological dete
Since the end of the Cold War, Western powers have frequently used sanctions to fight declining levels of democracy and human rights violations abroad. However, some of the world’s most repressive autocracies have never been subjected to sanctions, while other more competitive authoritarian regimes have been exposed to repeated sanction episodes. In this article, we concentrate on the cost–benefit
This work presents an event-based control structure using the generalized predictive control (GPC) algorithm with actuator deadband. The main objective of this work is to limit the number of controlled system updates. In this approach, the controlled process is sampled with a constant sampling time and is updated in an asynchronous way that depends on the obtained control signal value. To achieve
This work presents an x-ray absorption measurement by use of ionizing radiation generated by a femtosecond pulsed laser source. The spectrometer was a microcalorimetric array whose pixels are capable of accurately measuring energies of individual radiation quanta. An isotropic continuum x-ray spectrum in the few-keV range was generated from a laser plasma source with a water-jet target. X rays wer
The causative microorganisms dictate the type of MDSC generated in sepsis patients, and a large proportion of PMN-MDSCs in gram-positive sepsis includes immunosuppressive myeloid blasts. MDSCs constitute a heterogeneous population of immature myeloid cells that potently suppress immune responses. They were identified originally in cancer patients and have since been reported to occur also in chron
This paper is a methodological ethnography aiming to highlight the difficulties in using conventional methods in connection with an explorative philosophy; Deleuze and Guattari’s. Taking an empirical point of departure in conversations about the future with students in upper secondary school, the struggle to find a scientifically valid label through the focus group interview is outlined. However,
The aim was to study possible associations between smoking habits and self-reported clinical features in a large population-based cohort of patients with psoriatic arthritis (PsA). All subjects with PsA who had sought health care in the period 2003-2007 were identified using a regional health-care register. In 2009, all those identified who were 18 years of age or more (n = 2,003) were sent a ques
