Sensory consequences resulting from own movements receive different neural processing compared to externally generated sensory consequences (e.g., by a computer), leading to sensory attenuation, i.e., a reduction in perceived intensity or brain evoked responses. However, discrepant findings exist from different cultural regions about whether sensory attenuation is also present for sensory conse...

Attenuation due to rain is a primary cause of communication impairment on satellite-earth paths, especially above 10GHz. Rainfall is a serious source of attenuation at such a frequency. This paper presents the characteristics of rain distribution in USM based on measured one minute rain rate. For attenuation of rain, predictions models like ITU and VIHT (Variable Isotherm Height Technique) mode...

Total attenuation in ground-penetrating radar (GPR) was directly measured in radargrams of the Bishop Tuff, CA, from 12.5–200 MHz. The weak variation of attenuation with frequency reaffirms the "GPR Plateau" concept and argues against a constant-Q model. Electrolytic absorption —determined using collocated DC resistivity profiling/ sounding—accounts for about half of the attenuation and is by d...

background: in diagnostic radiology lead apron, are usually used to protect patients and radiology staff against ionizing radiation. lead apron is a desirable shield due to high absorption and effective attenuation of x-ray photons in the diagnostic radiology range. objective: although lead aprons have good radiation protection properties, in recent years, researchers have been looking for alte...
