Ampicillin and its congener prodrugs in the horse
(1994-03)Ampicillin is an antibiotic commonly administered to horses by both the intramuscular (i.m.) and the intravenous (i.v.) route. Its physicochemical properties restrict its absorption after oral administration and explain ... -
Amplification of a Cytochrome P450 Gene Is Associated with Resistance to Neonicotinoid Insecticides in the Aphid Myzus persicae
(2010-06)The aphid Myzus persicae is a globally significant crop pest that has evolved high levels of resistance to almost all classes of insecticide. To date, the neonicotinoids, an economically important class of insecticides ... -
Amplituhedra, and Beyond
(2020-12-29)This review is a primer on recently established geometric methods for observables in quantum field theories. The main emphasis is on amplituhedra, i.e. geometries encoding scattering amplitudes for a variety of theories. ... -
Amplituhedron meets Jeffrey-Kirwan Residue
(2018-12-28)The tree amplituhedra A^(m)_n,k are mathematical objects generalising the notion of polytopes into the Grassmannian. Proposed for m=4 as a geometric construction encoding tree-level scattering amplitudes in planar N=4 super ... -
Amyloid β-peptide(1-42) and hydrogen peroxide-induced toxicity are mediated by TRPM2 in rat primary striatal cultures
(2005)Amyloid β-peptide (Aβ) is the main component of senile plaques which characterize Alzheimer's disease and may induce neuronal death through mechanisms which include oxidative stress. To date, the signalling pathways linking ... -
Anabolic androgenic steroid abuse in the United Kingdom: An update
(2020-05)Anabolic androgenic steroids (AASs) are prescribed for medical conditions related to low testosterone. Abuse of AASs has surged as they become recognised as potent image enhancement drugs. The primary goal of most abusers ... -
Analisi dei report online relativi al potenziale uso errato della benzidamina
(2013)Benzydamine/Tantum Rosa is a drug for external use. It is typically available in Europe, without the need of a medical prescription, for the treatment of vaginal inflammatory processes. Between December 2009 and January ... -
An Analog of the Feigin-Frenkel homomorphism for double loop algebras
(2021-12-15)We prove the existence of a homomorphism of vertex algebras, from the vacuum Verma module over the loop algebra of an untwisted affine algebra, whose construction is analogous to that of the Feigin-Frenkel homomorphism ... -
Analogical reasoning in schizophrenic delusions
(2004)Reasoning ability has often been argued to be impaired in people with schizophrenic delusions, although evidence for this is far from convincing. This experiment examined the analogical reasoning abilities of several groups ... -
Analyses of air samples for ascospores of Leptosphaeria maculans and L.biglobosa by light microscopy and molecular techniques
(2009)Spores of many fungal pathogens are dispersed by wind. Detection of these airborne inocula is important in forecasting both the onset and the risk of epiphytotics. Species-specific primers targeted at the internal transcribed ... -
The Analyses of Individual Patient Pathways : Investigating Regional Variation in COPD readmissions
(Vilnius Gediminas Technical University Publishing House “Technika”, 2009-07-13)Regional variation for those treated for chronic obstructive pulmonary disease (COPD) has been studied amongst many public health issues. However, for those experiencing frequent readmissions were not considered. The ... -
Analysing and enhancing the performance of associative memory architectures
(University of Hertfordshire, 2003)This thesis investigates the way in which information about the structure of a set of training data with 'natural' characteristics may be used to positively influence the design of associative memory neural network models ... -
Analysing Ferret XML reports to estimate the density of copied code
(University of Hertfordshire, 2010)This document explains a method for identifying dense blocks of copied text in pairs of files. The files are compared suing Ferret, a copy-detection tool which computes a similarity score based on trigrams. This similarity ... -

Analysing globular cluster observations: Models and analysis tools for Lick/IDS indices
(2006)We have extended our evolutionary synthesis code, galev, to include Lick/IDS absorption-line indices for both simple and composite stellar population models (star clusters and galaxies), using polynomial fitting functions. ... -
Analysing Hierarchical Data Using a Stochastic Evolutionary Neural Tree
(1998)SCENT is simple competitive neural network model that evolves a tree structured set of nodes in response to being presented with an unlabelled data set. The resulting set of weight vectors and their relationship can be ... -
Analysing Multi-Color Observations of Young Star Clusters in Mergers
(Astronomical Society of the Pacific, 2003)We present a new evolutionary synthesis (ES) tool specifically developed for the analysis of multi-color data of young star clusters (YSCs) in interacting galaxies. Our ESO/ST-ECF ASTROVIRTEL1 project provides an unprecedented ... -
Analysing observed star cluster SEDs with evolutionary synthesis models: systematic uncertainties
(2004)We discuss the systematic uncertainties inherent to analyses of observed (broad-band) Spectral Energy Distributions (SEDs) of star clusters with evolutionary synthesis models. We investigate the effects caused by restricting ... -
Analysing political discourse: Toward a cognitive approach
(2005)The critical study of political discourse has up until very recently rested solely within the domain of the social sciences. Working within a linguistics framework, Critical Discourse Analysis (CDA), in particular Fairclough ... -
