Low Birth Weight and Risk of Obesity : A Potential Problem for the Japanese People
(2009)In the last half-century, obesity has constantly increased in Japanese adults except for women of childbearing age who often desire to be thin. Considering the lean composition of Japanese mothers and rather strict ... -
New results on long secondary periods in red giants
(2009)Approximately 30% of variable red giants have light curves which show a Long Secondary Period (LSP) in addition to their primary oscillation. No model has been proposed that can satisfactorily explain the LSPs. Here we ... -
Application of automatic differentiation to race car performance optimisation
(Springer Nature Link, 2002)A formal method for the evaluation of the minimum time vehicle manoeuvre is described. The problem is treated as one of optimal control and is solved using a direct transcription method. The resulting nonlinear programming ... -
Delegation and not-so smart cards
(1999)We consider three aspects of delegation: What kinds of binding are required between real world artifacts and bit patterns? What are the atomic elements of a security policy and in what ways must they fit together? What are ... -
Pictures Can’t Lie under Oath
(2000)Because image manipulation by computer is so easy, it is hard to be sure that an image was indeed created at the date, time and place claimed, and that it has not been altered since. To gain this confidence requires a ... -
Galaxy Zoo: the fundamentally different co-evolution of supermassive black holes and their early- and late-type host galaxies
(2010)We use data from the Sloan Digital Sky Survey and visual classifications of morphology from the Galaxy Zoo project to study black hole growth in the nearby universe (z < 0.05) and to break down the active galactic nucleus ... -
Trust* : Extending the Reach of Trust in Distributed Systems
(2010-03-08)Building trust is a common requirement in distributed environments especially since many transactions now occur on a person-to-person basis. Examples range from e-commerce on the Internet to peer-to-peer and grid resource ... -
Regulation of the Inducible L-Arginine-Nitric Oxide Pathway by Oxidative Stress and Statins
(2010-03-02)Oxidative stress (OS) plays a critical role in the pathogenesis of atherosclerosis potentially through interaction with nitric oxide (NO) generated by the inducible nitric oxide synthase (iNOS) pathway. Although considerable ... -
In Memoriam : On Bereavement and the Work of Mourning
(2009)In Memoriam is an elegy in the tradition of such great precedents as ‘Lycidas’ or ‘Adonais’. However, just as it incorporates the new worlds of scientific geology and evolutionary biology so, it is suggested, the poem ... -
CT response assessment combining reduction in both size and arterial phase density correlates with time to progression in metastatic renal cancer patients treated with targeted therapies
(2010)Background: Response assessment is critical in evaluating effectiveness of anticancer treatment. Tyrosine kinase inhibitors (TKIs) in renal cell carcinoma (RCC) are associated with significant clinical benefit but may not ... -
Switching stable patients with schizophrenia from depot and oral antipsychotics to long-acting injectable risperidone : reasons for switching and safety
(2010)Objective: An international, non-randomised study evaluated efficacy and safety of risperidone long-acting injectable (RLAI) compared to previous treatment. To investigate generisability of the European data set to the UK ... -
Mid-infrared photometry of cold brown dwarfs : diversity in age, mass and metallicity
(2010)We present new Spitzer Infrared Array Camera (IRAC) photometry of 12 very late-type T dwarfs: nine have [3.6], [4.5], [5.8], and [8.0] photometry and three have [3.6] and [4.5] photometry only. Combining this with previously ... -
Magnetar twists: Fermi/Gamma-Ray Burst Monitor detection of SGR J1550-5418
(2010)SGR J1550-5418 (previously known as AXP 1E 1547.0-5408 or PSR J1550-5418) went into three active bursting episodes in 2008 October and in 2009 January and March, emitting hundreds of typical soft gamma repeater bursts in ... -
User involvement in the development of a health promotion technology for older people: findings from the SWISH project
(2010)Successive English government policies about older people's health and well-being aim to improve health and quality of life by promoting independence. Improving access to information and services that can improve health ... -
Holonomy Embedding for Arbitrary Stable Semigroups
(2002)We show how the Rhodes expansion Ŝ of any stable semigroup S embeds into the cascade integral (a natural generalization of the wreath product) of permutation-reset transformation semigroups with zero adjoined. The permutation ... -
The Robot in the Swarm : An Investigation into Agent Embodiment within Virtual Robotic Swarms
(2003)This paper explores the notion of degree of embodiment within the context of autonomous agent research, specifically within swarms of virtual robotic agents. Swarms of virtual robots with systematically varied degrees of ... -
Evolving Embodied Genetic Regulatory Network-driven Control Systems
(2003)We demonstrate the evolution of simple embodied Genetic Regulatory Networks (GRNs) as real-time control systems for robotic and software-based embodied Artificial Organisms, and present results from two experimental ... -
An Experimental Analysis of Local Minima to Improve Neighbourhood Search
(2003)The paper reports the results from a number of experiments on local search algorithms applied to job shop scheduling problems. The main aim was to get insights into the structure of the underlying configuration space. We ... -
Approximation of Boolean Functions by Local Search
(2004)Usually, local search methods are considered to be slow. In our paper, we present a simulated annealing-based local search algorithm for the approximation of Boolean functions with a proven time complexity that behaves ...
