Longitudinal and azimuthal evolution of two-particle transverse momentum correlations in Pb-Pb collisions at √sNN= 2.76 TeV

This paper presents the first measurements of the charge independent (CI) and charge dependent (CD) two-particle transverse momentum correlators G2CI and G2CD in Pb–Pb collisions at √SNN=2.76 TeV by the ALICE collaboration. The two-particle transverse momentum correlator G2 was introduced as a measure of the momentum current transfer between neighboring system cells. The correlators are measure

The upgrade of the ALICE TPC with GEMs and continuous readout

The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we describe the design of new readout chambers and front-end electronics, which are driven by the goals of the experiment. Gas Electron Multiplier (GEM) detectors arranged in stacks containing four GEMs each, and continuous re

Swedish occupational therapists’ considerations for leaving their profession : outcomes from a national survey

Background: Occupational therapists are an essential healthcare profession and play a vital role in rehabilitating patients in the activities of daily life. Nevertheless, many occupational therapists in Sweden are leaving the profession and this jeopardises occupational therapy services. Objective: To explore factors that cause occupational therapists to seriously consider leaving their profession

Imaging Markers of Brain Frailty and Outcome in Patients With Acute Ischemic Stroke

BACKGROUND AND PURPOSE: Functional outcome after stroke may be related to preexisting brain health. Several imaging markers of brain frailty have been described including brain atrophy and markers of small vessel disease. We investigated the association of these imaging markers with functional outcome after acute ischemic stroke. METHODS: We retrospectively studied patients with acute ischemic str

Luftföroreningshalter på förskolegårdar

På uppdrag av Naturvårdsverket har avdelningen för Arbets- och miljömedicin vid Lunds Universitet utfört studie kring luftföroreningssituationen på förskolegårdar.Denna studie består av tre delar vara av en är en kunskapsinventering bland landets kommuner kring luftkvalitén på förskolebarns utemiljöer och effekter/strategier för att eventuellt förbättra detta.

Poorly Expressed Alleles of Several Human Immunoglobulin Heavy Chain Variable Genes are Common in the Human Population

Extensive diversity has been identified in the human heavy chain immunoglobulin locus, including allelic variation, gene duplication, and insertion/deletion events. Several genes have been suggested to be deleted in many haplotypes. Such findings have commonly been based on inference of the germline repertoire from data sets covering antibody heavy chain encoding transcripts. The inference process

Biallelic variants in LIG3 cause a novel mitochondrial neurogastrointestinal encephalomyopathy

Abnormal gut motility is a feature of several mitochondrial encephalomyopathies, and mutations in genes such as TYMP and POLG, have been linked to these rare diseases. The human genome encodes three DNA ligases, of which only one, ligase III (LIG3), has a mitochondrial splice variant and is crucial for mitochondrial health. We investigated the effect of reduced LIG3 activity and resulting mitochon

Stadens sociala ordning : Stånd och klass i Malmö under sjuttonhundratalet

I denna bok presenteras nya perspektiv på det svenska ståndssamhället. Det görs genom en undersökning av Malmö mellan 1720 och 1780. Ståndssamhället var något mycket mer än bara indelningen i adel, präster, borgare och bönder. Stånd var beroende av att gränser mellan grupper markerades genom olika juridiska rättigheter. Det handlade dock inte bara om juridik. Statusindelningar upprätthölls i befol

3D nano-tomography using coherent X-rays

X-rays allow to non-destructively investigate biological, chemical or physical processes at thenano-scale. Their high penetration depth in matter allows to investigate samples even in-side sample environments, which would be difficult with complementary methods such astransmission electron microscopy (TEM). The microscopy technique ptychography has beenestablished in X-ray imaging in recent years.X-rays allow to non-destructively investigate biological, chemical or physical processes at the nano-scale.

The Struggles of Light Bound in Matter : Modelling Optical Excitations in Nanostructures

This thesis addresses three different topics on the interaction between light and matter in open quantum systems. The first topic concerns two-dimensional spectroscopy and the spectral contributions from different nonlinear action signals with a focus on how to differentiate between them. The second topic concerns the thermalization of excited electrons in hot-carrier solar cells with a focus on h

Electronic correlations at paramagnetic (001) and (110) NiO surfaces : Charge-transfer and Mott-Hubbard-type gaps at the surface and subsurface of (110) NiO

We explore the interplay of electron-electron correlations and surface effects in the prototypical correlated insulating material, NiO. In particular, we compute the electronic structure, magnetic properties, and surface energies of the (001) and (110) surfaces of paramagnetic NiO using a fully charge self-consistent DFT+ dynamical mean-field theory method. Our results reveal a complex interplay b

Neuronal Replacement in Stem Cell Therapy for Stroke : Filling the Gap

Stem cell therapy using human skin-derived neural precursors holds much promise for the treatment of stroke patients. Two main mechanisms have been proposed to give rise to the improved recovery in animal models of stroke after transplantation of these cells. First, the so called by-stander effect, which could modulate the environment during early phases after brain tissue damage, resulting in mod

Patient satisfaction and loyalty in Japanese primary care : a cross-sectional study

Background: This study aimed to explore associations between various elements of primary care, patient satisfaction, and loyalty. Methods: This cross-sectional study used a modified version of the Primary Care Assessment Tool (PCAT), which was adapted for Japan. We distributed the PCAT questionnaire to patients aged 20 years or older at five rural primary care centres in Japan. We confirmed the va

Mobile research labs to explore nature-based solutions in Japanese cities : - a way to bridge disciplinary divides?

The mobile research lab is an emerging research methodology increasingly applied in urban studies to investigate phenomena like places, infrastructures, nature and inhabitants of cities. This essay critically explores this relatively new methodology, also known as ‘mobile labs’, as part of in-situ research for a two-year research project supported by the International Fellowship Program of the JapThe mobile research lab is an emerging research methodology increasingly applied in urban studies to investigate phenomena like places, infrastructures, nature and inhabitants of cities.

Performance analysis of daily global solar radiation models in peru by regression analysis

Solar radiation (Rs) is one of the main parameters controlling the energy balance at the Earth’s surface and plays a major role in evapotranspiration and plant growth, snow melting, and environmental studies. This work aimed at evaluating the performance of seven empirical models in estimating daily solar radiation over 1990–2004 (calibration) and 2004–2010 (validation) at 13 Peruvian meteorologic
