Experiments on the thermoelectric properties of quantum dots

Quantum dots (QDs) are good model systems for fundamental studies of mesoscopic transport phenomena using thermoelectric effects because of their small size, electrostatically tunable properties and thermoelectric response characteristics that are very sensitive to small thermal biases. Here we provide a review of experimental studies on thermoelectric properties of single QDs realized in two-dime

ESS target helium experiments at Lund University

In ESS, a 5 MW proton beam will hit a helium cooled tungsten target to generate neutrons by spallation. For the purpose of investigating various aspects of cooling with helium, an experimental system has been constructed at Lund University, Department of Energy Sciences. A helium flow of 3 g/s is circulated in a closed loop with pre-heater, cooler, filters and a test vessel. The vessel has windows

Student explanations of their science teachers’ assessments, grading practices and how they learn science

The current paper draws on data generated through group interviews with students who were involved in a larger ethnographic research project performed in three science classrooms. The purpose of the study from which this data was generated, was to understand science teachers’ assessment practices in an upper-secondary school in Sweden. During group interviews students were asked about their concep

The National Early Warning Score : Translation, testing and prediction in a Swedish setting

The National Early Warning Score – NEWS is a “track and trigger” scale designed to assess in-hospital patients’ vital signs and detect clinical deterioration. In this study the NEWS was translated into Swedish and its association with the need of intensive care was investigated. A total of 868 patient charts, recorded by the medical emergency team at a university hospital, containing the parameter

Binding-affinity predictions of HSP90 in the D3R Grand Challenge 2015 with docking, MM/GBSA, QM/MM, and free-energy simulations

We have estimated the binding affinity of three sets of ligands of the heat-shock protein 90 in the D3R grand challenge blind test competition. We have employed four different methods, based on five different crystal structures: first, we docked the ligands to the proteins with induced-fit docking with the Glide software and calculated binding affinities with three energy functions. Second, the do

Three presents : On the multi-temporality of territorial production and the gift from John Soane

Territoriality has primarily been seen as a spatial rather than temporal phenomenon. In this paper, we want to investigate how time functions in territorialising processes. In particular, we are attracted by the multi-temporality that is co-present in each process of territorialisation (i.e. processes in which time and space are used as means of measure, control and expression). The article is div

A Comparison of Rule-based Analysis with Regression Methods in Understanding the Risk Factors for Study Withdrawal in a Pediatric Study

Regression models are extensively used in many epidemiological studies to understand the linkage between specific outcomes of interest and their risk factors. However, regression models in general examine the average effects of the risk factors and ignore subgroups with different risk profiles. As a result, interventions are often geared towards the average member of the population, without consid

High frequency III-V nanowire MOSFETs

III-V nanowire transistors are promising candidates for very high frequency electronics applications. The improved electrostatics originating from the gate-all-around geometry allow for more aggressive scaling as compared with planar field-effect transistors, and this can lead to device operation at very high frequencies. The very high mobility possible with In-rich devices can allow very high dev

Rapidity dependence of the average transverse momentum in hadronic collisions

The energy and rapidity dependence of the average transverse momentum (pT) in pp and pA collisions at energies currently available at the BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC) are estimated using the color glass condensate (CGC) formalism. We update previous predictions for the pT spectra using the hybrid formalism of the CGC approach and two phenomenologi

Inactivation of TGFβ receptors in stem cells drives cutaneous squamous cell carcinoma

Melanoma patients treated with oncogenic BRAF inhibitors can develop cutaneous squamous cell carcinoma (cSCC) within weeks of treatment, driven by paradoxical RAS/RAF/MAPK pathway activation. Here we identify frequent TGFBR1 and TGFBR2 mutations in human vemurafenib-induced skin lesions and in sporadic cSCC. Functional analysis reveals these mutations ablate canonical TGFβ Smad signalling, which i

The Meaning of Environmental Management : An Interpretive Study of Managing Emergent or Evolutionary Environmental and Energy Strategy

Because of the vital roles of industry in sustainable development, it is essentialthat environmental management is effective in preventing pollution. To this end,environmental management systems have been implemented to a growing extent inindustry. Moreover, this Ph.D. research has demonstrated that environmentalmanagement efforts must be systematic to use environmental performanceindicators effec

Multi-pitch estimation via fast group sparse learning

In this work, we consider the problem of multi-pitch estimation using sparse heuristics and convex modeling. In general, this is a difficult non-linear optimization problem, as the frequencies belonging to one pitch often overlap the frequencies belonging to other pitches, thereby causing ambiguity between pitches with similar frequency content. The problem is further complicated by the fact that

Stone Tablets, Memorial Texts and Agency in Late-Medieval Scandinavian Castles : The Examples of Glimmingehus and Olofsborg

This paper explores how noblemen expressed themselves in late-medieval Scandinavian castles, in the buildings and in the landscape. The focus is on decorated stone tablets with coats of arms and memorial texts found on the castle walls, but the landscape setting of the castles is also discussed. The examples considered here are Glimmingehus in Scania, in present-day southern Sweden, and Olofsborg

Reporting of complex interventions in clinical trials : Development of a taxonomy to classify and describe fall-prevention interventions

Interventions for preventing falls in older people often involve several components, multidisciplinary teams, and implementation in a variety of settings. We have developed a classification system (taxonomy) to describe interventions used to prevent falls in older people, with the aim of improving the design and reporting of clinical trials of fall-prevention interventions, and synthesis of eviden
