Search for dark photons from neutral meson decays in p plus p and d plus Au collisions at root s(NN)=200 GeV

The standard model (SM) of particle physics is spectacularly successful, yet the measured value of the muon anomalous magnetic moment (g - 2)mu deviates from SM calculations by 3.6 sigma. Several theoretical models attribute this to the existence of a "dark photon," an additional U(1) gauge boson, which is weakly coupled to ordinary photons. The PHENIX experiment at the Relativistic Heavy Ion Coll

Detailed diesel exhaust characteristics including particle surface area and lung deposited dose for better understanding of health effects in human chamber exposure studies.

Several diesel exhaust (DE) characteristics, comprising both particle and gas phase, recognized as important when linking with health effects, are not reported in human chamber exposure studies. In order to understand effects of DE on humans there is a need for better characterization of DE when performing exposure studies. The aim of this study was to determine and quantify detailed DE characteri

Electron reconstruction and identification efficiency measurements with the ATLAS detector using the 2011 LHC proton-proton collision data

Many of the interesting physics processes to be measured at the LHC have a signature involving one or more isolated electrons. The electron reconstruction and identification efficiencies of the ATLAS detector at the LHC have been evaluated using proton-proton collision data collected in 2011 at TeV and corresponding to an integrated luminosity of 4.7 fb. Tag-and-probe methods using events with lep

Swedish hunters' safety behaviour and experience of firearm incidents

Since any firearm injury is potentially lethal, it is of great interest to prevent firearm incidents. This study investigated such incidents during hunting and Swedish hunters' safety behaviour. A 48-item questionnaire was posted to a random sample of 1000 members of the Swedish Association for Hunting and Wildlife Management. The questions considered demographics, hunting experience/hunting habit

Electronic properties of grain boundaries in Cu(In,Ga)Se-2 thin films with various Ga-contents

We present a study on the electronic properties of grain boundaries (GBs) in polycrystalline Cu(In,Ga)Se-2 (CIGSe) thin films by means of Kelvin probe force microscopy. As grown as well as KCN-treated films were investigated comparatively. No influence of the chemical treatment on the electronic properties of GBs was found. GBs generally exhibited large variations in their electronic properties. B

Size, Shape, and Charge of Salt-Free Catanionic Microemulsion Droplets: A Small-Angle Neutron Scattering and Modeling Study.

The formation and microstructure of a novel microemulsion based on a salt-free catanionic surfactant have been examined by considering the hexadecyltrimethylammonium octylsulfonate (TASo)-decane-D(2)O system and using small-angle neutron scattering and self-diffusion NMR. With focus on the emulsification failure boundary, o/w discrete droplets have been observed and characterized for all of the st

Grazing-incidence spectrometer on the SSPX spheromak

The silver flat field spectrometer (SFFS) is a high-resolution grazing-incidence diagnostic for magnetically confined plasmas. It covers the wavelength range of 25-450 A with a resolution of Delta lambda=0.3 A full width at half maximum. The SFFS employs a spherical 1200 lines/mm grating for flat-field focusing. The imaging is done using a backilluminated Photometrics charge-coupled device camera

Will restrictions on CO2 emissions require reductions in transport demand?

In this paper, the potential for the transportation sector to develop in a way that is consistent with long-term climate targets will be discussed. An important question is whether technical measures will be sufficient for reaching long-term climate targets. Although there is a large potential to significantly increase the use of bioenergy from today's level, there will be severe restrictions to i

Experience from Two Resistivity Inversion Techniques Applied in Three Cases of Geotechnical Site Investigation

The combination of in situ geotechnical testing and continuously measured geophysical data can be a powerful tool in geotechnical site investigation. In two cases from Sweden and one case from Denmark electric resistivity surveys are used successfully in geotechnical site investigations. The main contribution of resistivity results is the possibility to interpret continuous geological models. An i

Heat-treated and homogenised potato pulp suspensions as additives in low-fat sausages

Differently homogenised and heat treated potato pulp, used as a dietary fibre additive in low-fat sausages, gave rise to an enhanced instrumentally and sensory measured firmness and compactness, respectively. This is believed to be due to the high content of insoluble fibre, which creates a fibrous network that enhances the texture of the sausage, while not interfering with the meat protein networ

Förhållandet mellan anföringssats och anförd sats vid direkt anföring

Vid direkt anföring uppvisar såväl anföringssats som anförd sats huvudsats¬egenskaper och det är inte uppenbart hur förhållandet mellan satserna i en anförd mening ska förstås. I denna uppsats undersöks det hierarkiska förhållandet mellan anföringssats och an¬förd sats ur såväl semantisk/pragmatisk som syntaktisk synvinkel. Undersökningens utgångs¬punkt är tre antaganden om huvud- och bisatser: 1)

A New Algorithm for Solving Ring-LPN With a Reducible Polynomial

The learning parity with noise (LPN) problem has recently proved to be of great importance in cryptology. A special and very useful case is the Ring-LPN problem, which typically provides improved efficiency in the constructed cryptographic primitive. We present a new algorithm for solving the Ring-LPN problem in the case when the polynomial used is reducible. It greatly outperforms the previous al

On the Kalman-Yakubovich-Popov Lemma for Positive Systems

The classical Kalman-Yakubovich-Popov lemma gives conditions for solvability of a certain inequality in terms of a symmetric matrix. The lemma has numerous applications in systems theory and control. Recently, it has been shown that for positive systems, important versions of the lemma can equivalently be stated in terms of a diagonal matrix rather than a general symmetric one. This paper generali

A novel nonlinear model reduction method applied to automotive controller software

The automotive industry is experiencing tightening emission legislations together with high demands on performance and driveability. As a counteraction, controller software tends to become more and more complex. Intricate controller software has several downsides, the large number of controller parameters yields an exhaustive calibration task, often performed through costly experiments. In additio

Repeat polymorphisms in ESR2 and AR and colorectal cancer risk and prognosis: results from a German population-based case-control study

Background: Evidence has accumulated which suggests that sex steroids influence colorectal cancer development and progression. We therefore assessed the association of repeat polymorphisms in the estrogen receptor beta gene (ESR2) and the androgen receptor gene (AR) with colorectal cancer risk and prognosis. Methods: The ESR2 CA and AR CAG repeat polymorphisms were genotyped in 1798 cases (746 fem

Neuroblastoma aggressiveness in relation to sympathetic neuronal differentiation stage.

Neuroblastoma is a childhood malignancy of the sympathetic neuronal lineage. It is a rare disease, but since it is frequently diagnosed during infancy, neuroblastoma causes life-long medical follow up of those children that survive the disease. It was early recognized that a high tumor cell differentiation stage correlates to favorable clinical stage and positive clinical outcome. Today, highly di
