Assessing the whole-body absorption in a human in a realistic environment requires a statistical approach covering all possible exposure situations. This article describes the development of a statistical multi-path exposure method for heterogeneous realistic human body models. The method is applied for the 6-year-old Virtual Family boy (VFB) exposed to the GSM downlink at 950 MHz. It is shown ...

The organ-specific averaged specific absorption rate (SARosa) in a heterogeneous human body phantom, the Virtual Family Boy, is determined for the first time in (five) realistic electromagnetic environments at the Global System for Mobile communications downlink frequency of 950 MHz. We propose two methods, based upon a fixed set of finiteStochastic Method for the Determination of Organ-Specifi...

Background: Regarding the wide domain of microwaves applications in human life, yet its biologic impacts on human body cells are discussed. Therefore our goal is the investigation of mobile phone microwaves with frequency of 950 MHz on apoptotic changes of epididymis in rabbits. Materials and Methods: 18 male New Zealand rabbits were randomly divided into 2 experiment group and 1 control group....

Introduction: Stroke causes death and disability in patients throughout the world. At present, the only FDA- approved drug for ischemic stroke is recombinant tissue plasminogen activator (rt- PA). Unfortunately, rtPA can cause intracerebral hemorrhage and must use within limited time window (within 3-4.5 hour after onset of stroke). Ultrasound with rtPA loaded liposomes (rtPA_L...

We report Kerr-lens mode-locked polycrystalline Cr(2+):ZnS lasers at 2.4 μm central wavelength optimized for short pulse duration. By control of the second- and third-order dispersion within 500 nm bandwidth we obtained pulses of three optical cycles (<29  fs) at 100 MHz repetition rate with 0.44 W average power. The emission spectrum is 240 nm broad at -3  dB level and spans 950 nm at -30  dB ...
