male infertility is a distressingly common condition affecting about 1 in 20 of the male population. in a majority of the cases, the male partner produces sufficient numbers of spermatozoa to achieve fertilization but there are functional defects in these cells that prevent conception from occurring. in this study, the effects of wi-fi radiation on spermatogenesis, testes and testosterone of la...

In this paper we describe our configurable hotspot framework for ubiquitous interaction. A camera points to a physical space, the user defines interaction areas, and designs gestures by combining hotspots (rectangles) that detect simple 2D motions (left_right, top_bottom, etc.).

Computed tomography (CT)/magnetic resonance imaging (MRI) fusion is considered to be the best method for postimplant dosimetry of permanent prostate brachytherapy; however, it is inconvenient and costly. In T2*-weighted image (T2*-WI), seeds can be easily detected without the use of an intravenous contrast material. We present a novel method for postimplant dosimetry using T2*-WI/T2-weighted im...

I discuss the nature of ‘hotspots’ and ‘jet knots’ in the kpc-scale structures of powerful radio galaxies and their relationship to jet-environment interactions. I describe evidence for interaction between the jets of FRI sources and their local environments, and discuss its relationship to particle acceleration, but the main focus of the paper is the hotspots of FRIIs and on new observational ...

PURPOSE To develop an accurate method of fusing computed tomography (CT) with magnetic resonance imaging (MRI) for post-implant dosimetry after prostate seed implant brachytherapy. MATERIAL AND METHODS Prostate cancer patients were scheduled to undergo CT and MRI after brachytherapy. We obtained the three MRI sequences on fat-suppressed T1-weighted imaging (FST1-WI), T2-weighted imaging (T2-W...
