Two variable step size (VSS) techniques are proposed for adaptive decorrelation filtering (ADF) to improve the performance of competing speech separation. The first VSS method applies gradient adaptive step-size (GAS) to increase ADF convergence rate. Under some simplifying assumptions, the GAS technique is generalized to allow the combination with additional VSS techniques for ADF algorithm. T...

Today, patients aged 15–44 years have at least a 50% chance of surviving a 70% total body surface area (TBSA) burn when treated in a specialist burns unit. Burns comprise up to 30% of combat injuries, depending on the nature of the conflict. However, a significant proportion — up to half — of burn injuries sustained by military personnel may not be combat-related, and are amenable to preventive...

Professor John Barbur’s research interests cover fundamental studies of visual mechanisms as well as applied and clinical research. He studied physics, applied optics and vision sciences at Imperial College and then moved to City University where his research formed the basis for the Applied Vision Research Centre in 1986. His current interests include motion perception, pupil responses, scatte...

James McCarthy is Head of the Clinical Tropical Medicine Laboratory at the Queensland Institute of Medical Research, and a consultant Infectious Diseases Physician at the Royal Brisbane and Women’s Hospital. His current projects involve work on drug resistance in human scabies, hookworm and malaria. Michelle Gatton’s research interests focus on the use of theoretical models to better understand...

One option is to reduce the biting density by killing adult and larval mosquitoes with insecticides and by using b rrier in ecticide sprays on tentage and surrounding foliage. These methods are suitable in static base locations, but not for protecting patrolling soldi...

Actin plays important roles in a number of synaptic processes, including synaptic vesicle organization and exocytosis, mobility of postsynaptic receptors, and synaptic plasticity. However, little is known about the mechanisms that control actin at synapses. Actin dynamics crucially depend on LIM kinase 1 (LIMK1) that controls the activity of the actin depolymerizing proteins of the ADF/cofilin ...

BACKGROUND Alternate day fasting (ADF; ad libitum "feed day", alternated with 25% energy intake "fast day"), is effective for weight loss and cardio-protection in obese individuals. Whether these effects occur in normal weight and overweight individuals remains unknown. This study examined the effect of ADF on body weight and coronary heart disease risk in non-obese subjects. METHODS Thirty-t...

The relation between alternate-day fasting (ADF) and cardioprotection remains uncertain. In the present study, we examined the ability of modified ADF, with a low-fat (LF) vs high-fat (HF) background diet, to modulate adipose tissue physiology in a way that may protect against coronary heart disease. In a 4-week study, male C57BL/6 mice were randomized to 1 of 3 groups: (1) ADF-85%-LF (85% ener...

11 to report this threat to Ms Tarasoff directly. However, the psychologist did tell his supervising psychiatrist, who reported the matter to the campus police, who interviewed Mr Poddar, but let him go. After the murder, the girl’s parents sued the psychologist (or, rather, his employer) for “failure to warn”, in that no warning was conveyed to their daughter. The trial Court held that no such...
