Hormonal Modulation of Perception in Motivation-Based Action Selection Architectures
(The Society for the Study of Artificial Intelligence and the Simulation of Behaviour (AISB), 2005)The animat approach to artificial intelligence proposes biologically-inspired control mechanisms for autonomous robots. One of the related subproblems is action selection or what to do next . Many action selection architectures ... -
A Hormone-Driven Epigenetic Mechanism for Adaptation in Autonomous Robots
(2018-06-01)Different epigenetic mechanisms provide biological organisms with the ability to adjust their physiology and/or morphology and adapt to a wide range of challenges posed by their environments. In particular, one type of ... -
The horse handlers
(2007-09-01)Despite its enormous potential for harm, research suggests that some people, in certain circumstances, feel able to effectively manage and control their use of heroin in order to minimise risks. The authors have followed ... -
Horticulture and the Environment in the Southern Region : Final Report for Environment Agency, Southern Region
(Environment Agency, 2006-11-14)The Environment Agency, Southern Region, commissioned this scoping study to assess the potential environmental risks and impacts of horticulture in the Region. Much of Southern Region is environmentally sensitive due to ... -
The Hospital Anxiety and Depression Scale : a meta confirmatory factor analysis
(2013-01)Objective: To systematically evaluate the latent structure of the Hospital Anxiety and Depression Scale (HADS) through reanalysis of previous studies and meta confirmatory factor analysis (CFA). Method: Data from 28 samples ... -
Hospital mealtimes: action research for change
(2005)Poor nutritional care within the hospital setting continues despite decades of work chronicling--and measuring the problems. To address the problem changes in practice have been attempted--to improve the patients experience ... -
Hospitality and Home: British and American Cultures of Entertaining
(Bloomsbury Academic, 2020-11-26)The eighty years from 1920 to 2000 saw tremendous changes in the ways that hospitality was practiced in people’s homes. These transformations were brought about by broader cultural shifts - acting in different ways within ... -
Host Dark Matter Halos of SDSS Red and Blue Quasars: No Significant Difference in Large-scale Environment
(2022-03-02)The observed optical colors of quasars are generally interpreted in one of two frameworks: unified models that attribute the color to the random orientation of the accretion disk along the line of sight, and evolutionary ... -
Host Dark Matter Halos of Wide-field Infrared Survey Explorer-selected Obscured and Unobscured Quasars: Evidence for Evolution
(2023-03-23)Obscuration in quasars may arise from steep viewing angles along the dusty torus, or instead may represent a distinct phase of supermassive black hole growth. We test these scenarios by probing the host dark matter halo ... -
The Host Galaxies of Hybrid Morphology Radio Sources
(2022-12-16)Based on their differing radio morphologies, powerful radio galaxies can be separated into the Fanaroff-Riley I (FR I) and II (FR II) classes. Hybrid morphology radio sources (HyMoRS) contain morphologies consistent with ... -
Host pathogen interactions in relation to management of light leaf spot disease (caused by Pyrenopeziza brassicae) on Brassica species
(2017)Light leaf spot, caused by Pyrenopeziza brassicae, is currently the most damaging disease problem in oilseed rape in the UK. According to recent survey data, the severity of epidemics has increased progressively across the ... -
Host plant root exudates reduce phytonematode cuticle aging to maintain Pasteuria endospore attachment
(2022-03-17)Endospores of the nematode hyperparasite from the Pasteuria group of Gram-positive bacteria have the potential to suppress phytonematode populations and reduce root infection. Parasitism by the bacteria commences when ... -
Host species determines egg size in Oriental cuckoo
(2018-11-02)The Oriental cuckoo Cuculus optatus is an obligate brood parasite associated with species of the genus Phylloscopus. Four distinct phenotypes of Oriental cuckoo eggs, matching eggshell colour patterns of Arctic warbler ... -
The host stars of extrasolar planets have normal lithium abundances
(2000)The lithium abundances of planet-harbouring stars have been compared with those of open clusters and field stars. Young (chromospherically active) and subgiant stars have been eliminated from the comparison because they ... -
Hostile Environments: Immigration and Food Poverty in the UK
(University of Hertfordshire, 2022-12-13)As part of The Food Foundation’s wider project to re-shape the public narrative on food and inequalities, this research was commissioned to focus on families with NRPF and food poverty. The aim of this study was to explore ... -
Hot and cold gas accretion and feedback in radio-loud active galaxies
(2007)We have recently shown that X-ray observations of the population of ‘low-excitation’ radio galaxies, which includesmost low-power, Fanaroff-Riley class I sources as well as some more powerful Fanaroff-Riley class II objects, ... -
The hot gas distribution, X-ray luminosity and baryon budget in the L-Galaxies semi-analytic model of galaxy formation
(2023-03-31)Hot ionized gas is important in the baryon cycle of galaxies and contributes the majority of their ``missing baryons''. Until now, most semi-analytic models of galaxy formation have paid little attention to hot gaseous ...
