Physics, Compact Modeling and TCAD of SiGe HBT for Wide Temperature Range Operation
(2011-11-29)
One of the remarkable characteristics of SiGe HBT is the ability to operate over a wide temperature range, from as low as sub 1K, to as high as over 400 K. The SiGe HBT investigated and measured in this work is a ...
Physics, Modeling and Design Implications of RF Correlated Noise in SiGe HBTs
(2013-05-01)
Accurate noise compact modeling and
efficient noise extraction techniques are required for RF circuit design.
Understanding the impact of noise sources and the noise propagation is also necessary for
device and circuit ...
A Physics-Based Framework for Estimating Real-Time Platoon Energy Savings
(2024-05-06)
Platooning is a strategy that aims to reduce aerodynamic drag and fuel consumption by driving trucks closely behind each other. However, the advantages of platooning can be compromised by braking loss, which refers to the ...
Physiological Adaptations to a Concurrent Sprint Interval and Resistance Training Program in Aging Women
(2016-12-19)
PURPOSE: To investigate the physiological adaptations to a high intensity concurrent exercise training (CET) program composed of Sprint Interval Training (SIT) and Resistance Exercise Training (RET) in recreationally active ...
Physiological and behavioral effects of photosynthetically-active radiation on rosetip sea anemones Condylactis gigantea: Tolerance limits and growth
(2018-07-24)
Irradiance is an abiotic factor that strongly affects the metabolism of endosymbiotic Symbiodinium within photosynthetic cnidarians such as rose tip sea anemones Condylactis gigantea. Fluctuations in the intensity of ...
Physiological and behavioral impacts of railway noise on stream fishes
(2019-04-17)
While the expansion of anthropogenic noise studies in aquatic habitats has produced conservation-based results for marine organisms, little attention has been paid to the potential impacts of anthropogenic noise on freshwater ...
Physiological and Molecular Responses of Feeding Ractopamine toYearling Heifers Across Days on Feed
(2010-05-05)
Heifers comprise 30% of the annual beef harvest in the United States. Production pressures over the past several years have lead to a need to increase production efficiency. One mode currently available is the use of the ...
Physiological and nutritional requirements for the culture of the Pacific white shrimp, Litopenaeus vannamei, in low salinity waters
(2006-08-15)
The culture of the Pacific white shrimp, Litopenaeus vannamei, in inland low salinity well waters (LSWW) is a promising, fledgling industry in Alabama. Despite the success of a small number of farmers in producing L. ...
Physiological and Phenological Responses to Experimental Throughfall Reduction and Parameterization of the 3-PG Model for Modeling Long-Term Responses to Climate Change in Longleaf Pine Forests
(2021-11-29)
Ongoing changes in the earth’s climate are having profound effects on forest ecosystems in many regions. Longleaf pine (Pinus palustris Mill.) is considered one of the most drought-resistant pines in the southeastern U.S. ...
Physiological Basis of Differential Sensitivity of Selected Graminaceous Species to Aminocyclopyrachlor
(2014-08-18)
Synthetic auxin herbicides are widely used in many grass systems due to their selective control of broadleaf weeds and safety to grass species. Aminocyclopyrachlor (ACPC) is a new synthetic auxin herbicide used for broadleaf ...
Physiological Comparison of Three Southern Highbush Blueberry Cultivars Under High Tunnel and Open Field Conditions
(2023-05-02)
Recent studies have shown that high tunnel production of blueberries generates higher biomass accumulation due to the microclimates created compared to open field production. This study aimed to evaluate the physiological ...
Physiological Correlates of Bat Rabies Pathogenesis and Epizootiology
(2014-07-24)
Rabies virus (RABV) is one model pathogen to consider for studying the dynamics of emerging infectious diseases under both laboratory and field conditions. The evolutionary history of RABV is characterized by regularly ...
Physiological costs of reproduction in female mice
(2020-02-07)
The hypothesis that the large demand of reproduction negatively impacts future reproduction and/or survival has become a major topic in many fields within biology. Although many assume negative linear correlations between ...
The Physiological Effects of Bright Plumage Coloration
(2008-08-15)
Songbirds with extensive, carotenoid-based plumage tend to maintain high levels of circulating carotenoids in plasma, which could represent a potential tradeoff between maintaining brightness at the expense of carotenoid-related ...
