A comparison of methods for traversing regions of non-convexity in optimization problems
(2019-11-13)This paper considers the well-known problem of dealing with non-convexity during the minimization of a non-linear function f(x) by Newton-like methods. The proposal made here involves a curvilinear search along an approximation ... -
A comparison of methods to assess the antimicrobial activity of nanoparticle combinations on bacterial cells
(2018-02-01)BACKGROUND: Bacterial cell quantification after exposure to antimicrobial compounds varies widely throughout industry and healthcare. Numerous methods are employed to quantify these antimicrobial effects. With increasing ... -
A comparison of methods to determine neuronal phase-response curves
(2010)The phase-response curve (PRC) is an important tool to determine the excitability type of single neurons which reveals consequences for their synchronizing properties. We review five methods to compute the PRC from both ... -
A comparison of methods to estimate anaerobic capacity: Accumulated oxygen deficit and W' during constant and all-out work-rate profiles.
(2017-12-02)This study investigated (i) whether the accumulated oxygen deficit (AOD) and curvature constant of the power-duration relationship (W') are different during constant work-rate to exhaustion (CWR) and 3-min all-out (3MT) ... -
A comparison of modelling methods for forecasting light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape in the UK
(British Crop Protection Council, 2000-11) -
A Comparison of Modelling Strategies for Value-Added Analyses of Educational Data
(University of Hertfordshire, 2000)Modelling strategies for value-added multilevel models are examined. These types of models typically include an endogenous variable and this causes difficulties for the standard estimation techniques that are commonly used ... -
Comparison of neurokinin SP with diazepam in effects on memory and fear parameters in the elevated T-maze free exploration paradigm
(2001)The elevated T-maze was combined with a free exploration protocol, which, in contrast to the conventional procedure, dispenses with handling of the animals during the experimental sessions. This allows measurement of fear ... -
Comparison of Nutritional Intake of Free Living Adults Aged ≥75 Years Receiving Home Delivered Meals with Dietary Reference Values
(2014)House-bound older adults are at risk of malnutrition. However there is limited knowledge of dietary intake in this population in the UK. The 'meals on wheels' (MOW) service delivers meals to this population to help meet ... -
Comparison of optical and microphysical properties of pure Saharan mineral dust observed with AERONET Sun photometer, Raman lidar, and in situ instruments during SAMUM 2006
(2012-04-14)The Saharan Mineral Dust Experiment (SAMUM) 2006, Morocco, aimed at the characterization of optical, physical, and radiative properties of Saharan dust. AERONET Sun photometer, several lidars (Raman and high-spectral-resolution ... -
Comparison of Oral, Intranasal and Aerosol Administration of Amiodarone in Rats as a Model of Pulmonary Phospholipidosis.
(2019-07-17)‘Foamy’ alveolar macrophages (FAM) observed in nonclinical toxicology studies during inhaled drug development may indicate drug-induced phospholipidosis, but can also derive from adaptive non-adverse mechanisms. Orally ... -
Comparison of oritavancin versus vancomycin as treatments for clindamycin-induced Clostridium difficile PCR ribotype 027 infection in a human gut model
(2008)To compare the efficacy of oritavancin and vancomycin in the treatment of Clostridium difficile infection (CDI) using an in vitro human gut model. -
A comparison of outcome for stroke patients in Barbados and South London
(2011)Background and aims: Little is known about the poststroke outcome in Caribbean populations. We investigated differences in the activities of daily living, level of social activities, living circumstances and survival for ... -
A Comparison of Paranoid Ideation in Clients with Psychosis or Anxiety Disorders During an Interactive Video Task
(2009-01-19)Background. Previous studies have shown that the use of simulated social environments permits paranoid thinking to be studied. These studies have used a cognitive model of paranoia and suggest that anxiety is an important ... -
Comparison of pediatric and adult antibiotic-associated diarrhea and Clostridium difficile infections
(2016-03-21)Antibiotic-associated diarrhea (AAD) and Clostridium difficile infections (CDI) have been well studied for adult cases, but not as well in the pediatric population. Whether the disease process or response to treatments ... -
Comparison of Pelvic Complex Kinematics During Treadmill and Overground Walking
(2012)OBJECTIVES: To determine if there are changes in temporal gait parameters with a focus on pelvis when comparing overground and treadmill ambulation, and to assess the effect of sex. DESIGN: An observational study employing ... -
Comparison of pepsinogen forms in cattle, sheep and goats
(1990)Different types and subtypes of pepsinogen extracted from bovine, ovine and caprine abomasa were found to differ according to their phosphate content and relative molecular mass (Mr). Bovine pepsinogens had organic phosphate ... -
Comparison of planktonic and biofilm-associated communities of Clostridium difficile and indigenous gut microbiota in a triple-stage chemostat gut model
(2014-04-30)BACKGROUND: Biofilms are characteristic of some chronic or recurrent infections and this mode of growth tends to reduce treatment efficacy. Clostridium difficile infection (CDI) is associated with a high rate of recurrent ... -
