Logarithmic simulated annealing for computer-assisted x-ray diagnosis
(2001)We present a new stochastic learning algorithm and first results of computational experiments on fragments of liver CT images. The algorithm is designed to compute a depth-three threshold circuit, where the first layer is ... -
Combining the perception algorithm with logarithmic simulated annealing
(2001)We present results of computational experiments with an extension of the Perceptron algorithm by a special type of simulated annealing. The simulated annealing procedure employs a logarithmic cooling schedule (-), where ... -
Bounded-depth threshold circuits for computer-assisted CT image classification
(2001)We present a stochastic algorithm that computes threshold circuits designed to discriminate between two classes of computed tomography (CT) images. The algorithm employs a partition of training examples into several classes ... -
The NHS plan : accounting for investment and reform in twenty acute hospital trusts in England (1998–2003)
(2005)The National Health Service (NHS) Plan published in 2000 summarised Labour's commitment to modernising the NHS in England. The NHS would receive substantial additional funding bringing expenditure on health, as a share in ... -
Incorporating sustainability indicators into a computable general equilibrium model of the Scottish economy
(2005)In recent years, the notion of sustainable development has begun to figure prominently in the regional, as well as the national, policy concerns of many industrialized countries. Indicators have typically been used to ... -
What baboons, babies and Tetris players tell us about interaction : a biosocial view of norm-based social learning
(2006)Could androids use movements to build relationships? For people, relationships are created with the help of behaviour-shaping norms, which infants begin to discover and manipulate by the third month. To build relationships, ... -
Putting apes, (body and language) together again
(2003)It is argued that the account of Savage-Rumbaugh's ape language research in Savage-Rumbaugh, Shanker and Taylor (1998. Apes, Language and the Human Mind. Oxford University Press, Oxford) is profitably read in the terms of ... -
Evidence for a dissociation of structural and semantic knowledge in dementia of the Alzheimer type (DAT)
(2007)Object recognition and naming deficits in dementia of the Alzheimer type (DAT) have typically been attributed to deficits in semantic processing, with only a few studies proposing loci of deficits other than semantic. One ... -
Effects of chronic intraventricular infusion of heparin glycosaminoglycan on learning and brain acetylcholine parameters in aged rats
(2003)We reported previously that the glycosaminoglycan heparin (HP) has the facility to improve learning in adult rodents when administered into the nucleus basalis of the ventral pallidum. Here we gauged the effects of chronic ... -
Facilitation of learning and modulation of frontal cortex acetylcholine by ventral pallidal injection of heparin glucosaminoglycan
(2002)We examined the effects of heparin on learning and frontal cortex acetylcholine parameters following injection of the glucosaminoglycan into the ventral pallidum. In Experiment 1, possible mnemoactive effects of intrapallidal ... -
Enhanced maze performance and reduced oxidative stress by combined extracts of zingiber officinale and ginkgo biloba in the aged rat
(2002)Here we assessed the effects of i.g. administration of Zingicomb (ZC), a mixture of zingiber officinale and ginkgo biloba extracts, on learning and memory, and on indicators of oxidative stress in aged rats. Effects of ZC ... -
Comparison of intra-accumbens injection of histamine with histamine H1-receptor antagonist chlorpheniramine in effects on reinforcement and memory parameters
(2001)Histaminergic neurons are located exclusively in the tuberomammillary nuclei (TM) of the hypothalamus from where they project to many regions of the brain including the basal ganglia. Earlier experiments led to the hypothesis ... -
Phonological memory and rule learning
(2005)Our research reflects the current trend to relate individual differences in second language learning to underlying cognitive processes (e.g., Robinson, 2002). We believe that such investigations, apart from being of practical ... -
Output decay in immediate serial recall : Speech time revisited
(2002)Four experiments reexamined the hypothesis that immediate serial recall is limited by the spoken duration of list items during output. In all the experiments, spoken serial recall was measured for visually presented words ... -
"..it depends on the risk." Constructing 'Antipsychotic' Medication 'Refusal' in Community 'Mental Health' Services
(2011-02-18)Aim Antipsychotic medication is the predominant intervention used for psychosis in the UK. However, there are risks associated, it is not always effective and service-users express ambivalence towards taking it. The ... -
A Re-Conceptualisation of Contemporary Sculpthural Ceramics From a Post-Minimalist Perspective
(2011-02-17)This thesis examines the extent to which the 1960s process art strand of post-Minimalism can provide an analytical template for critical writing around contemporary ceramic art. A dearth of critical writing is an acknowledged ... -
Counselling children and young people who attend a school for children with complex needs : a case study
(2005)We report the findings of a case study exploring the views of the student, teacher, teaching assistant and counsellor who participated in a project to evaluate counselling with young people who attend a school for children ... -
A computer adaptive test that facilitates the modification of previously entered responses : An empirical study
(2004)In a computer-adaptive test (CAT), learners are not usually allowed to revise previously entered responses. In this paper, we present findings from our most recent empirical study, which involved two groups of learners and ... -
The magnetic environments of young stellar objects
(2004)We report on early results of submillimetre polarimetric measurements towards a sample of young stellar objects. The results allow us to infer the magnetic field structure and show a variety of configurations, providing ... -
Hα and Hel emission in the jets of pre-main sequence stars : implications for the heating mechanisms
(2003)Jets and winds in pre-main sequence (PMS) stars are often heated and ionized, and understanding their heating mechanism is desired to compare UV-to-IR spectral signatures with models and thus investigate their driving ...
