Comparison of Fragmentation Functions for Jets Dominated by Light Quarks and Gluons from pp and Pb+Pb Collisions in ATLAS

Charged-particle fragmentation functions for jets azimuthally balanced by a high-transverse-momentum, prompt, isolated photon are measured in 25 pb-1 of pp and 0.49 nb-1 of Pb+Pb collision data at 5.02 TeV per nucleon pair recorded with the ATLAS detector at the Large Hadron Collider. The measurements are compared to predictions of Monte Carlo generators and to measurements of inclusively selected

Finite volume based multigrid preconditioners for discontinuous Galerkin methods

Our aim is to construct efficient preconditioners for high order discontinuous Galerkin (DG) methods. We consider the DG spectral element method with Gauss‐Lobatto‐Legendre nodes (DGSEM‐GL) for the 1D linear advection equation. It has been shown in [4] that DGSEM‐GL has the summation‐by‐parts (SBP) property and an equivalent finite volume (FV) discretization is presented in [3]. Thus we present a

How can language be grounded – in a deconstructionist semiotics?

Deconstruction is one of the more (in)famous theories in recent times. In this paper, I argue that the theory of deconstruction, proposed by Derrida in particular, should be read as a systematic and rigorous examination of key philosophical and semiotic notions, such as sign and meaning. The relevance of taking deconstructive critique seriously is explored with the point of departure in Derrida’s

Non-actual motion in language and experience

Dynamic descriptions of static situations, e.g. The road goes through the forest, have attracted a lot of attention in semantics. In cognitive linguistics, terms such as “fictive motion” and “subjective motion” are often used to describe such sentences. While these terms are taken to be largely synonymous, I argue that they are analytically different, and furthermore point to different possible ex

Subcell finite volume multigrid preconditioning for high-order discontinuous Galerkin methods

We suggest a new multigrid preconditioning strategy for use in Jacobian-free Newton–Krylov (JFNK) methods for the solution of algebraic equation systems arising from implicit Discontinuous Galerkin (DG) discretisations. To define the new preconditioner, use is made of an auxiliary first-order finite volume discretisation that refines the original DG mesh, but can still be implemented algebraically

Allopurinol in addition to 5-aminosalicylic acid based drugs for the maintenance treatment of ulcerative colitis

BACKGROUND: To investigate the value of combined treatment with allopurinol and 5-aminosalicylic (5-ASA) based drugs as maintenance treatment for ulcerative colitis (UC).METHODS: 199 patients with UC in remission but with active disease during the preceding 3 years were included. Allopurinol 100 mg twice daily or placebo was added to the 5-ASA based maintenance treatment. Clinical and endoscopic f

Gastroduodenal morphology and related symptoms in chronic alcoholics

Twenty-four chronic alcoholics admitted to hospital for detoxification after a drinking spree were examined by upper gastrointestinal endoscopy. Biopsy specimens were taken from corpus/fundus, antrum and duodenum for tissue histology (eosin stain). From the duodenum villus index and ultrastructure (scanning electron microscopy, SEM) were also performed. As a control group 12 subjectively healthy n

The structures underpinning vulnerability : Examining landscape-society interactions in a smallholder coffee agroforestry system

Smallholder farmers dependent on rain-fed agriculture are particularly vulnerable to extreme climate events and, therefore, it is necessary to identify adaptive measures that would increase farmer resilience to these shocks. The management options in a low-input system, like forest coffee (Coffea arabica), are limited and there are several factors out of farmers' control driving their vulnerabilit

Metabolism of chylomicron phosphatidylinositol in the rat : fate in vivo and hydrolysis with lipoprotein lipase and hepatic lipase in vitro

Phosphatidylinositol (PI), mainly stearoyl-arachidonyl PI, occurs as a minor phospholipid constituent in both chyle and plasma lipoproteins. The kinetics and the pathway by which plasma and chyle PI is metabolized have not been investigated. The role of lipoprotein PI in the supply of arachidonic acid (20:4) and inositol lipid components to different tissues is thus unknown. In this study we exami

Sources of diacylglycerols for phospholipid synthesis in rat liver

The biosynthesis of molecular species of phosphatidylethanolamine and phosphatidylcholine in isolated rat liver parenchymal cells was studied with [32P]phosphate and [3H]glycerol as precursors. Addition to the cells of albumin-bound oleic or linoleic acid resulted in the synthesis of high proportions of dioleoyl- or dilinoleoyl-phospholipids, especially from labeled glycerol. The fact that these s

Realizability and internal model control on networks

It is proved that network realizability of controllers can be enforced without conservatism using convex constraints on the closed loop transfer function. Once a network realizable closed loop transfer matrix has been found, a corresponding controller can be implemented using a network structured version of Internal Model Control.
