The paper proposes a restoration method for speckled images generated by coherent imaging systems (e.g., synthetic aperture radar, synthetic aperture sonar, ultrasound imaging, and laser imaging). These systems are invariably affected by speckle noise and therefore restoration/filtering of the mean backsattered signal (backsacttering coefficient) is often necessary. The approach is Bayesian: th...

The primary purpose of humanoid telepresence cyber-physical systems is to faithfully reproduce user intent in the remote robot. One of the main challenges lies in maintaining bipedal balance during complex behaviour such as walking, or negotiating obstacles whilst operating in a changing environment. The aim is to achieve this dynamic balance during human-controlled motion, and determine an eff...

the role of oxygen free radicals in the initiation, promotion and progression of carcinogenesis and the protective role of anti-oxidant defenses has been the subject of much speculation in the recent past with conflicting reports in the literature. in recent years, increasing experimental and clinical data have provided compelling evidence for the involvement of oxidative stress in a large numb...

BACKGROUND Speckled rattlesnakes (Crotalus mitchellii) inhabit multiple islands off the coast of Baja California, Mexico. Two of the 14 known insular populations have been recognized as subspecies based primarily on body size divergence from putative mainland ancestral populations; however, a survey of body size variation from other islands occupied by these snakes has not been previously repor...
