Background: The issue of a potential association between thyroid conditions/hormones and breast cancer has been studied extensively during the last decades but the results have been inconclusive and almost no studies have investigated breast cancer aggressiveness. We have previously found a positive association between prospectively measured levels of triiodothyronine (T3) and breast cancer incide

The ATLAS (A Toroidal LHC ApparatuS) Inner Detector provides charged particle tracking in the centre of the ATLAS experiment at the Large Hadron Collider (LHC). The Inner Detector consists of three subdetectors: the Pixel Detector, the Semiconductor Tracker (SCT), and the Transition Radiation Tracker (TRT). This paper summarizes the tests that were carried out at the final stage of SCT+TRT integra

Most visual systems are more sensitive to luminance than to colour signals. Animals resolve finer spatial detail and temporal changes through achromatic signals than through chromatic ones. Probably, this explains that detection of small, distant, or moving objects is typically mediated through achromatic signals. Macroglossum stellatarum are fast flying nectarivorous hawkmoths that inspect flower

Neutron reflectivity (NR) measurements have been performed on stimulus-responsive polymer brushes containing N-isopropylacrylamide (NIPAAM) at different temperatures and contrasts using two different brush samples of roughly the same grafting density and layer thickness. The NR data were analyzed using a novel method employing polymer density profiles predicted from lattice mean-field theory augme

The α-synuclein protein (αS), implicated in Parkinson's disease (PD), shows conformational versatility. It aggregates into β-sheet-rich fibrils, occurs in helical membrane-bound forms, is disordered as a free monomer, and has recently been suggested to have a folded helical tetramer as its main physiological form. Here we use implicit solvent all-atom Monte Carlo (MC) methods to explore the confor

High resolution photoelectron spectroscopy and density functional theory calculations have been used to study the composition of clean and oxidized Pd75Ag25( 100). The results for the clean surface confirm earlier reports of surface segregation by Wouda et al. (1998), where the top most layers are rich in Ag. The Pd 3d core level component from the surface region is observed at higher binding ener

Landfill leachates usually need to be treated before discharged. and using soil-plant systems for this has gained substantial interest in Sweden and in the UK A three-year field study was conducted in central Sweden to quantify plant response, treatment efficiency and impact on groundwater quality of landfill leachate irrigation of short-rotation willow coppice (Salix) Two willow varieties were te

Nowadays, 'investigation' is a very commonly advocated approach and consequently is becoming an umbrella concept. 'Investigation' includes many types of approaches on different system levels. Originating from transport accidents and crime scenes, 'investigation' ranges from genocide, natural disasters, via discrimination, health care to crime fighting, economic fraud and ethical questions in engin

We have investigated the base-collector breakdown voltage of type I InGaAs/InP DHBTs, which is shown to be dominated by band-to-band tunneling in the base-collector grade. By optimizing the grade we obtain a 20% increase in the breakdown voltage compared with traditional grades.

Nanowire heterostructures define high-quality few-electron quantum dots for nanoelectronics, spintronics, and quantum information processing. We use a cooled scanning probe microscope (SPM) to image and control an InAs quantum dot in an InAs/InP nanowire using the tip as a movable gate. Images of dot conductance vs tip position at T=4.2 K show concentric rings as electrons are added, starting with

This paper devises a new way of measuring the geographical scope of innovation based on patent data and compares its geographical distribution with that of patents granted and production. Indicators of patent quality are used to form an index of regional innovation, which is argued to be an improvement over patent counts, which are seen as indicators of inventions. Innovations are more concentrate

This article discusses ethics and equality using the philosophy of Emmanuel Levinas within the field of educational relations. Levinas usually focuses on ethics, but in this article I also discuss his parallel political dimension which makes equality possible. Levinas’ argument of infinite asymmetrical positions is used in an expanded sense to also include infinite individuals. This leads to a vie

This Letter describes a model-independent search for the production of new resonances in photon + jet (gamma + jet) events using 20 fb(-1) of proton-proton LHC data recorded with the ATLAS detector at a centre-of-mass energy of root s = 8 TeV. The gamma + jet mass distribution is compared to a background model fit from data; no significant deviation from the background-only hypothesis is found. Li

A measurement of the multi-strange Xi(-) and Omega(-) baryons and their antiparticles by the ALICE experiment at the CERN Large Hadron Collider (LHC) is presented for inelastic proton-proton collisions at a centre-of-mass energy of 7 TeV. The transverse momentum (p(T)) distributions were studied at mid-rapidity (vertical bar y vertical bar < 0.5) in the range of 0.6 < p(T) < 8.5 GeV/c Xi(-) for an
