The pseudorapidity (η) and transverse-momentum (pT) distributions of charged particles produced in proton–proton collisions are measured at the centre-of-mass energy s=13 TeV. The pseudorapidity distribution in |η|<1.8 is reported for inelastic events and for events with at least one charged particle in |η|<1. The pseudorapidity density of charged particles produced in the pseudorapidity region |η

We study local (also referred to as small-signal) stability of a network of identical DC/AC converters having a rotating degree of freedom by closing the loop with the matching control at each converter. We develop a stability theory for a class of partitioned linear systems with symmetries that has natural links to classical stability theories of interconnected systems but improves upon them. We

Introduction: One of the vital skills which has an impact on emotional health and well-being is the regulation of emotions. In recent years, the neural basis of this process has been considered widely. One of the powerful tools for eliciting and regulating emotion is music. The Anterior Cingulate Cortex (ACC) is part of the emotional neural circuitry involved in Major Depressive Disorder (MDD). Th

Glas är ett genomsiktligt material som används i byggnader för att utforma miljöer som är ljusa och upplevs som öppna. Modernt byggnadsglas används i konstruktioner som utsätts för betydande laster jämfört med ett traditionellt fönsterglas. Som exempel kan nämnas trappsteg, balustrader, golv, tak och väggpaneler där glasets geometriska utformning kan vara mer eller mindre komplex. Det finns ett beNovel and increased use of glass in building construction has been made possible, as a result of methods of mass production introduced during the 20th century and advanced computational structural analyses. With modern use of glass structures, a range of demands emerge which need to be addressed in the strength design process. The aim of the thesis work has been to develop experimentally verified

Spleen cells from WF rats immunized to allogeneic lymphoid cells or to syngeneic colon carcinomas and from unimmunized controls were separated by countercurrent distribution in aqueous two-phase systems. The cells were assayed for cytotoxicity to allogeneic fibroblasts or syngeneic colon carcinoma cells and to syngeneic fibroblasts in a 24-hr 51Cr-release assay. Cells from immunized rats which sel

This paper is dedicated to model order reduction of linear time-invariant systems. The main contribution of this paper is the derivation of two scalable stability-preserving model reduction algorithms. Both algorithms constitute a development of a recently proposed model reduction method. The algorithms perform a curve fitting procedure using frequency response samples of a model and semidefinite

Background. Systemic sclerosis (SSc) is an autoimmune disease where thickening of the skin can lead to reduced body function and limitations in activities. Severe forms can also affect and seriously damage inner organs. Patient-centred rehabilitation emphasises considerations of patients' background, experience and behavior which highlights the need to know if patient-reported outcome measures (PR

Oxalate oxidase catalyses the degradation of oxalic acid to carbon dioxide and hydrogen peroxide and is of commercial importance for clinical analyses of oxalate in biological samples. Novel potential applications for oxalate oxidase include the prevention of the formation of calcium oxalate incrusts in pulp and paper manufacture and rapid determination of oxalic acid in process waters. The potent

A spatially one-dimensional model of the hydrodynamics of a flotation column is based on one continuous phase, the fluid, and two disperse phases: the aggregates, that is, bubbles with attached hydrophobic valuable particles, and the solid particles that form the gangue. A common feed inlet for slurry mixture and gas is considered and the bubbles are assumed to be fully aggregated with hydrophobic

This paper is built upon recognizing the need that digital forensic investigators are required in many cases to investigate, understand and report on all kind of cyber-crime including novel security breaches which have not been performed in the past. When an investigator is faced with the challenge to explore a new threat, we argue that the inquiry dynamics do not differ from an organisational emp
