We present updated NLO predictions for the electroweak t-channel production of heavy quarks at the Tevatron and at the LHC. We consider production of single top and fourth generation t′ starting from both 2 → 2 and 2→3 Born processes. Predictions for tb′ and t′b′ cross sections at NLO are also given for the first time. A thorough study of the theoretical uncertainties coming from parton distributi
Venous compliance in the calf of humans and its importance for capacitance function in relation to age were studied with the aid of 22, 44, and 59 mmHg lower body negative pressure (LBNP). Negative pressure transmission to the calf as well as changes in calf volume were studied, and venous compliance was calculated [change in volume with pressure change (dV/dP)]. The change in capacitance response
Although researchers across the social sciences speak of a linguistic turn, most research exploring culture still assumes a traditional perspective on language, which conceives meaning as representation. Yet, Wittgenstein convincingly criticized the epistemological basis of such a perspective, offering an alternative view on language. The paper begins by explaining the central points of a performa
AimThe aim was an in‐depth exploration of uncertainty and self‐efficacy among parents of a child with congenital cataract by means of two theoretical frameworks to re‐design family care.DesignA directed content analysis in accordance with Hsieh & Shannon, using Mishel's theory of uncertainty and Bandura's self‐efficacy theory.MethodsOpen‐ended, in‐depth interviews were conducted with 23 parent
Duplicate, bilateral structures of individual animals are usually symmetrical. In cases where such structures are asymmetrical, the degree of asymmetry may indicate the propensity of an individual to stray from the genetically programmed outcome during the development of the structure. Asymmetries have recently been assumed to constitute an honest signal of male quality and, as such, a cue for fem
Bradykinin receptors have been identified in human gingival fibroblasts; the primary signal transduction pathways and their dependence on calcium have been characterized. Binding data revealed a calcium-independent binding of bradykinin to the cell membrane with a receptor density of 25,000 receptors per cell and a K d
This work covers qualitative and quantitative requirements with regard to material propertiesfor cutting tools to be able to resist and balance the various interactive mechanisms that causethe wear of the cutting edge and put limits its tool life. In metal cutting, tool life T combinedwith the cutting data (cutting speed, feed and depth of cut) controls largely the manufacturingcost and related co
Purpose: The purpose of this paper is to explore the current trends, implications and challenges of information systems (IS) related to omni-channel logistics. Design/methodology/approach: An exploratory survey study is conducted with 23 Swedish retail companies transforming to omni-channel logistics. The study investigates the retailers’ current situations regarding logistics IS as well as their
Most crash prediction models are statistically-based prediction methods which require significant efforts in crash data collection and may not be applied in particular traffic environments due to the limitation of data sources. Traffic conflict studies have been proposed to mitigate this issue using short time survey to count traffic conflicts which are assumed as a surrogate measure of safety. Un

Type 1 (insulin-dependent) diabetes mellitus is associated with HLA DR and DQ factors, but the primary risk alleles are difficult to identify because recombination events are rare in the DQ-DR region. The risk of HLA genotypes for type 1 diabetes was therefore studied in more than 420 incident new onset, population-based type 1 diabetes children and 340 age, sex and geographically matched controls
Purpose: Hardly anything is known about the aetiology of thymoma. This paper presents data regarding tobacco smoking and alcohol consumption in relation to thymoma from the first case-control study performed on this rare tumour. Methods: A European multi-centre case-control study including incident cases aged 35–69 years with thymoma between 1995 and 1997, was conducted in seven countries. A set o
This paper analyses the underlying reasons why innovators do not apply for trademarks for all of their valuable inventions. Using a unique database of UK innovations linked to innovative firms, the empirical analysis highlights the many ways that firms can alleviate information asymmetries and the constraints imposed by collaborative innovation without taking recourse to trademarks. When informati
A large body of research has found an association between short birth intervals and the risk of infant mortality in developing countries, but recent work on other perinatal outcomes from highly developed countries has called these claims into question, arguing that previous studies have failed to adequately control for unobserved heterogeneity. Our study addresses this issue by estimating within-f
We give a short overview of the theory of the muon anomalous magnetic moment with emphasis on the hadronic light-by-light and the pion loop contribution. We explain the difference between the hidden local symmetry and full VMD pion loop and discuss leading logarithms in the anomalous sector of 2-flavour chiral perturbation theory.
Background: Fatigue is common among people with multiple sclerosis (MS), and significantly influences engagement in occupations. The Managing Fatigue (MF) programme is an evidence-based occupational therapy group-based intervention, utilising self-management science that provides people with tools to manage fatigue. Although the national MS-guidelines in Sweden cite this as best practice, a Swedis
A key assumption conventionally made by flexible head-mounted eye-tracking systems is often invalid: The eye center does not remain stationary w.r.t. the eye camera due to slippage. For instance, eye-tracker slippage might happen due to head acceleration or explicit adjustments by the user. As a result, gaze estimation accuracy can be significantly reduced. In this work, we propose Grip, a novel g
Objective: To develop evidence-based guidelines for the management of giant cell arteritis (GCA) as a complement to guidelines in other areas of rheumatology, issued by the Swedish Society of Rheumatology. Methods: A working group selected key areas for recommendations, reviewed the available evidence, and wrote draft guidelines. These were discussed and revised according to standard procedures wi
