The segmentation of MRI scans of patients with white matter lesions (WML) is difficult because the MRI characteristics of white matter lesions are similar to those of grey matter. Intensity based statistical classification techniques misclassify some WML as grey matter and some grey matter as WML. We developed a fast elastic matching algorithm that warps a reference data set containing informat...

Sequence variations in the melanocortin-1 receptor (MC1R) gene are associated with melanism in many different species of mammals, birds and reptiles. The grey squirrel (Sciurus carolinensis), found in the British Isles, was introduced from North America in the late nineteenth century. Melanism in the British grey squirrel is associated with a 24 base pair deletion in the MC1R. To investigate th...

BACKGROUND Grey matter, both volume and concentration, has been proposed as an endophenotype for schizophrenia given a number of reports of grey matter abnormalities in relatives of patients with schizophrenia. However, previous studies on grey matter abnormalities in relatives have produced inconsistent results. The aim of the present study was to examine grey matter differences between contro...

In the recent years, the optimization techniques using evolutionary algorithms have been widely used to solve electromagnetic problems. These algorithms use thinning the antenna arrays with the aim of reducing the complexity and thus achieving the optimal solution and decreasing the side lobe level. To obtain the optimal solution, thinning is performed by removing some elements in an array thro...

In-situ aluminum matrix composite is the innovation of high performance material technology and it has superior interfacial integrity and thermodynamic stability between the matrix and reinforcement. During synthesis, the ZrB2 particle is formed by exothermic reaction within the aluminum melt. As a result, small, fine and oxide free reinforcements are formed. Excessive temperature released from...

Modern production processes are heavily reliant on industrial control systems (ICS) to help automate large-scale facilities. The security of these systems is paramount as evidenced by high profile attacks such as those against Iran’s nuclear facilities and the Ukrainian Power Grid. Existing research has largely focused on technical measures against such attacks and little attention has been giv...

BACKGROUND Primary blepharospasm is a focal dystonia characterised by excessive involuntary closure of the eyelids. The pathophysiology of primary blepharospasm is unresolved. AIM To pinpoint grey-matter changes that are associated with primary blepharospasm. METHODS 16 right-handed patients with primary blepharospasm (mean age 67.4 (SD 4.3) years; 12 women) were compared with 16 healthy vo...
