3-Urea-1,8-naphthalimides are good chemosensors: a highly selective dual colorimetric and fluorescent ICT based anion sensor for fluoride
(2011)he 1,8-naphthalimide sensor 1 was developed as a colorimetric and fluorescent sensor for anions. Being the first example of such anion sensors, where the 3-position of the naphthalimide ring is used to incorporate the anion ... -
An active approach to guaranteed arrival times based on traffic shaping.
(2010)To address the goal of providing drivers on highways with guaranteed arrival times, we propose a traffic management system that combines virtual slots with semiautonomous driving to shape traffic and prevent congestion. Two ... -
Alignment instability caused by anchoring of the in-plane directors to the rubbing direction in the V-shaped switching
(2000)In order to investigate the molecular alignment in the smectic liquid crystals showing the V-shaped switching behavior, two types of the liquid crystal cells, a sandwiched cell and an open cell, were prepared. ... -
Altered Expression of Caspases-4 and -5 during Inflammatory Bowel Disease and Colorectal Cancer - Novel Diagnostic and Therapeutic Potential.
(2015)Caspases are a group of proteolytic enzymes involved in the co-ordination of cellular processes, including cellular homeostasis, inflammation and apoptosis. Altered activity of caspases, particularly caspase-1, has ... -
Alternating and direct current characterization and photoinduced absorption studies of modified conjugated polymer thin films
(2004)Control of interchain separation enables the optical properties of polymer thin films to be altered. We present a thin film preparation technique that increases the free volume fraction in spin coated polymer thin films ... -
Analysis of dynamic tyrosine phosphoproteome in LFA-1 triggered migrating T-cells.
(2011)The ordered, directional migration of T-lymphocytes is a key process during immune surveillance and response. This requires cell adhesion to the high endothelial venules or to the extracellular matrix by a series of surface ... -
Analysis of Strain and Intermixing in a Single Layer Ge/Si dots using polarized Raman Spectroscopy
(2006)The built-in strain and composition of as-grown and Si-capped single layers of Ge?Si dots grown at various temperatures (460?800 ?C) are studied by a comparative analysis of the Ge-Ge and Si-Ge modes in the polarized Raman ... -
Atorvastatin prevents age-related and amyloid-beta-induced microglial activation by blocking interferon-gamma release from natural killer cells in the brain
(2011)Abstract: Background: Microglial function is modulated by several factors reflecting the numerous receptors expressed on the cell surface, however endogenous factors which contribute to the age-related increase in microglial ... -
Attentional load asymmetrically affects early electrophysiological indices of visual orienting.
(2011)Recent behavioral studies suggest that asymmetries in visuospatial orienting are modulated by changes in the demand on nonspatial components of attention, but the brain correlates of this modulation are unknown. We used ... -
Band structures of rare gas solids within the GW approximation
(2005)Band structures for solid rare gases s Ne, Ar d have been calculated using the GW approximation. All electron and pseudopotential ab initio calculations were performed using Gaussian orbital basis sets and the ... -
Beyond the Role Model: Organisational modelling in policy based management systems
(2003)In this paper, we discuss recent developments in the field of Policy Based Management (PBM) and Role Based Access Control (RBAC).We postulate that PBM tends towards a total description of an organisation?s operations. We ... -
Cation-π interactions: complexes of Guanidinium and simple aromatic systems
(2011)We have theoretically studied, in gas phase and using PCM-water solvation, the complexes established by the biologically relevant guanidinium cation and simple aromatic systems (benzene, naphthalene and pyridine). In gas ... -
Cell Proliferation Tracking Using Graphene Sensor Arrays
(2012)The development of a novel label-free graphene sensor array is presented. Detection is based on modification of graphene FET devices and specifically monitoring the change in composition of the nutritive components in ... -
Comparative Imaging Study in Ultrasound, MRI, CT and DSA using a Multi-Modality Renal Artery Phantom
(2011)Purpose: A range of anatomically-realistic multi-modality renal artery phantoms consisting of vessels with varying degrees of stenosis was developed and evaluated using four imaging techniques currently used to detect renal ... -
A comparison of strain and fluid shear stress in stimulating bone cell responses - a computational and experimental study
(2005)Bone undergoes continuous remodeling in response to mechanical loading. However, the underlying mechanisms by which bone cells respond to their changing mechanical environment, that is, strain in the load-bearing matrix ... -
A comparison of the osteogenic potential of adult rat mesenchymal stem cells cultured in 2-D and on 3-D collagen glycosaminoglycan scaffolds.
(2007)Adult mesenchymal stem cells (MSCs) have the capability to differentiate along several lineages including those of bone, cartilage, tendon and muscle, thus offering huge potential for the field of tissue engineering. The ... -
Composition and Stress Analysis in Si/SiGe Structures
(IEEE, 2004)Strained Si tecbnology enables improvements in CMOS performance and functionality via replacement of the bulk, cubic-crystal Si substrate witb a Si substrate that contains a tetragonally distorted, biaxially strained ... -
Concise synthesis and CDK/GSK inhibitory activity of the missing 9-azapaullones
(2010)A remarkably concise, chromatography-free route to the parent compound of the paullone family of cyclin-dependent kinase (CDK) inhibitors is reported. A similar strategy allowed the synthesis of the hitherto missing ... -
