Abstract:
The ability to measure and quantify myocardial motion and deformation provides a useful tool to assist in the diagnosis, prognosis and management of heart disease. Myocardial motion can be measured by means of several different types of data acquisition. The earliest myocardial motion tracking technique was invasive, based on implanting radiopaque markers into the myocardium around the left ventricle, and recording the marker positions during the cardiac cycle by biplane cineradiography. Until recently, this was the only method with high enough spatial resolution of three-dimensional (3D) myoc

Abstract:
Recent guidelines for the management of stable coronary artery disease (CAD) and myocardial revascularisation emphasise the importance of the presence of ischaemia for guiding revascularisation. Cardiovascular Magnetic Resonance (CMR) perfusion imaging and fractional flow reserve (FFR) are two methods of physiological ischaemia assessment, one invasive and the other non-invasive. In order that the results are interpreted accurately, it is important to be aware of the limitations and advantages of each technique. These techniques measure different parameters so it is not uncommon that the two t

Abstract:
Most sarcomas of the bone occur in patients of a relatively young age including skeletally immature patients. Approximately 50 child sarcomas are treated with limb salvage surgery per year in the United Kingdom. These children need an extendible implant that can be lengthened periodically to keep pace with the growth in the opposite limb. Surgically, invasive devices have been used for the past thirty years with intrinsic problems of infection and long-term recurrent trauma to the patient.

Invasive and non-invasive methods of BTI monitoring and wearout preemption have been proposed. We propose a novel, simple to use, test structure for NBTI /PBTI monitoring.

A methodology of converting any data-path into ring oscillator (DPRO) is also presented.

Pulmonary hypertension (PH), a disease state affecting the pulmonary circulation, was first recognised in the 1950s. Obliteration of pulmonary capillary beds and vasoconstriction lead to elevated pulmonary vascular resistance (PVR) and increased right ventricular afterload. The direct consequence is impaired cardiac output (CO) response to exercise, resulting in progressive exercise limitation, and ultimately premature death from right heart failure. Despite the considerable expansion in pulmonary vasodilatory therapy in recent years, PH remains an incurable disease associated with high morbid

Abstract:
The eyes are acoustically continuous with the brain and inner ear tissues in regard to matched impedances, based on tissue densities, thus, vibration of one site will be reflected in all sites. With this being the case, the vibrational energy response of the eye due to an external source can be used to determine a correlation or draw a conclusion concerning the vibrational energy response of the brain would be. And since there is a correlation between the vibrational energies, any changes in the acoustical energy in the eye can possibly be used to determine the changes in acoustical energy i

Abstract:
HiPIMS discharges operated with a titanium and an aluminium-doped zinc target sputtered with the working gas argon were investigated by means of optical 2d-imaging in combination with Abel-inversion. By using optical bandpass filters, the spatial and temporal evolution of the plasma-induced emission of argon atoms and ions and metal atoms and ions were studied. The discharge ignition was found to be accompanied by an intensity maximum observed remote from the target, followed by an asymmetric intensity profile. During the stage of high discharge current, the intensity distribution indicates st
