Extremely high frequency of autoimmune-predisposing alleles in medieval specimens [PDF]
Journal of Zhejiang University SCIENCE B, 2007 The precise etiology and reasons for the increase in incidence of autoimmune disorders still remain unclear, and although both genetic and environmental factors have been proven to shape individual predisposition, it is not known which of the factors, if not both, is responsible for the boom observed during the last decades.

Frontiers in Pediatrics, 2020 Respiratory management of the extremely low birth weight (ELBW) newborn has evolved over time. Although non-invasive ventilation is being increasingly used for respiratory support in these ELBW infants, invasive ventilation still remains the primary mode

Extremely High Frequency RF Effects on Electronics [PDF]
, 2012 The objective of this work was to understand the fundamental physics of extremely high frequency RF effects on electronics. To accomplish this objective, we produced models, conducted simulations, and performed measurements to identify the mechanisms of effects as frequency increases into the millimeter-wave regime.

Active and Passive Electronic Components, 2000 New techniques to efficiently increase the frequency resolution of digital sinusoidal oscillators based on look-up-table (LUT) methods are proposed. The increase in frequency resolution is achieved while maintaining very low level of spurious harmonic ...

Vibrational Behavior of Metal Nanowires under Tensile Stress [PDF]
, 2011 We have investigated the vibrational density of states (VDOS) of a thin Cu nanowire with $$ axial orientation and considered the effect of axial strain. The VDOS are calculated using a real space Green's function approach with the force constant matrices

Effects of Frequency of “Extreme” Temperature Highs on Development of Soybean Rust [PDF]
Phytopathology®, 2013 Previously, we hypothesized that summer “extreme” diurnal temperature highs in the southeastern United States were responsible for the yearly absence or delay of soybean rust development until fall. Utilizing temperature-controlled growth chambers, a diurnal temperature pattern of 33°C high and 20°C low reduced urediniospore production by 81%. However,

Effect of acoustic pulses and EHF radiation on multipotent marrow stromal cells in tissue engineering constructs [PDF]
Journal of Innovative Optical Health Sciences, 2017 In this paper, we studied the effects of physical factors, such as, acoustic pulses of laser-induced hydrodynamics (ALIH) and extremely-high frequencies (EHF) radiation, on the formation of heterotopic bone marrow organs.
