Decomposition of neural circuits of human attention using a model based analysis: sSoTs model application to fMRI data (2008)
Journal Article

The complex neural circuits found in fMRI studies of human attention were decomposed using a model of spiking neurons. The model for visual search over time and space (sSoTS) incorporates different synaptic components (NMDA, AMPA, GABA) and a frequen...

Differential mechanisms of angiotensin II and PDGF-BB on migration and proliferation of coronary artery smooth muscle cells (2008)
Journal Article

Angiotensin II (Ang II) and platelet-derived growth factor-BB (PDGF-BB) are associated with excessive cell migration, proliferation and many growth-related diseases. However, whether these agents utilise similar mechanisms to trigger vascular patholo...

A simple evolutionary algorithm with self-adaptation for multi-objective nurse scheduling (2008)
Book Chapter

We present a multi-objective approach to tackle a real-world nurse scheduling problem using an evolutionary algorithm. The aim is to generate a few good quality non-dominated schedules so that the decision-maker can select the most appropriate one. O...

Cosmic string Y-junctions: a comparison between field theoretic and Nambu-Goto dynamics (2008)
Journal Article

We explore the formation of cosmic string Y-junctions when strings of two different types collide, which has recently become important since string theory can yield cosmic strings of distinct types. Using a model containing two types of local U(1) st... Read More about Cosmic string Y-junctions: a comparison between field theoretic and Nambu-Goto dynamics.

The classification of higher-order cusp forms (2008)
Journal Article

Explicit bases for the spaces of holomorphic cusp forms of all even positive weights and all orders are constructed. The dimensions of these spaces are computed.

Journal Article

Background: To determine the health needs of people with multiple sclerosis living in the Southern Derbyshire region of the UK, using a quality of life postal questionnaire. Methods: This was a population-based survey using a postal questionnaire com...

Temporal and between-site variation in helminth communities of bank voles (Myodes glareolus) from N.E. Poland. 1. Regional fauna and component community levels (2008)
Journal Article

Helminth infections were studied in bank voles (Myodes glareolus) from 3 woodland sites in N.E. Poland in the late summers of 1999 and 2002, to assess the temporal stability of derived statistics describing the regional helminth fauna and component c...

Species-specific kinetics and zonation of hepatic DNA synthesis induced by ligands of PPAR? (2008)
Journal Article

PPAR? ligands evoke a profound mitogenic response in rodent liver, and the aim of this study was to characterise the kinetics of induction of DNA synthesis. The CAR ligand, 1,4-bis[2-(3,5- dichoropyridyloxy)]benzene, caused induction of hepatocyte...

Administrative change in the Gulf: Modernization in Bahrain and Oman (2008)
Journal Article

States in the Middle East tend to be overlooked by researchers in comparative public administration. However, these states offer potentially useful insights into the nature of administrative change as they defy standard assumptions about pressures fo...

In utero effects on livestock muscle development and body composition (2008)
Journal Article

This review will focus on the evidence for in utero effects on development of skeletal muscle in farm and laboratory animals, particularly sheep and pigs. We will describe genetic and environmental factors that have been shown to alter the numbers of... Read More about In utero effects on livestock muscle development and body composition.

Allergen-driven suppression of thiol production by human dendritic cells and the effect of thiols on T cell function (2008)
Journal Article

Dendritic cells are a major source of extracellular thiols needed for T cell activation, a process in which CD40-mediated stimulation plays a pivotal role. The Dermatophagoides pteronyssinus group 1 mite allergen (Der p 1) has previously been shown t...

Implementation of a hybrid AC-AC direct power converter with unity voltage transfer (2008)
Journal Article

This paper presents a novel hybrid direct power converter (HDPC) which overcomes the two main disadvantages of matrix converters: limited voltage transfer ratio and low immunity to grid disturbance. The proposed converter is formed by integrating a r... Read More about Implementation of a hybrid AC-AC direct power converter with unity voltage transfer.

Introduction to Multi-Agent Simulation (2008)
Book Chapter

When designing systems that are complex, dynamic and stochastic in nature, simulation is generally recognised as one of the best design support technologies, and a valuable aid in the strategic and tactical decision making process. A simulation model... Read More about Introduction to Multi-Agent Simulation.

Hybrid matrix converter topologies: an exploration of benefits (2008)
Conference Proceeding

Matrix converters are direct AC/AC power converters that can operate with sinusoidal output/input voltage/currents without the need of passive components to store energy, which means that they are grid friendly and have a great weight/volume reductio...

Chemical Tags Facilitate the Sensing of Individual DNA Strands with Nanopores (2008)
Journal Article

The base resolution in the detection of single DNA strands with nanopores can be improved by attaching chemical tags to individual bases. Different chemical tags give rise to characteristic current signatures when a DNA molecule passes through a nano...

Differential Recognition of Staphylococcus aureus Quorum-Sensing Signals Depends on Both Extracellular Loops 1 and 2 of the Transmembrane Sensor AgrC (2008)
Journal Article

Virulence in Staphylococcus aureus is regulated via agr-dependent quorum sensing in which an autoinducing peptide (AIP) activates AgrC, a histidine protein kinase. AIPs are usually thiolactones containing seven to nine amino acid residues in which th...

Early life programming of hemispheric lateralization and synchronization in the adult medial prefrontal cortex (2008)
Journal Article

Neonatal maternal separation (MS) in the rat increases the vulnerability to stressors later in life. In contrast, brief handling (H) in early life confers resilience to stressors in adulthood. Early life programming of stress reactivity may involve t... Read More about Early life programming of hemispheric lateralization and synchronization in the adult medial prefrontal cortex.
