The Laplace transform is used to analyze the natural response and the step forced responses of resistor鈥揷apacitor (RC), resistor-inductor (RL), inductor-capacitor (LC), and resistor-inductor-capacitor (RLC) circuits. The concept of the impulse response of a circuit is presented. This, ...
Simplified formulae are developed for interior sound levels in terms of cavity, wall and external acoustic field parameters. Comparisons of theory and experiment show generally good agreement.关键词: Theoretical or Mathematical/ elasticity vibrations/ acoustic natural modes forced response sinusoidal ...
political risks in host countries significantly reduce Chinese investment and increase losses, and the BRI stimulates investment through mechanisms that seek to reduce policy uncertainty and political risks in host countries for Chinese firms.Third,the nature of this response is related to a substitution...

76. To directly assess how mandible size affected predation probability we used a GLM with a binomial distribution, a logit-link function, and overdispersion test. Male mandible size was used as the explanatory variable, and predation impact (preyed upon = 1, survive = 0) was the response ...

An organized, comprehensive, and security-enabled strategic response to the Haiti earthquake: a description of pre-deployment readiness preparation and pre... On Tuesday, January 12, 2010 at 16:53 local time, a magnitude 7.0 M(w) earthquake struck Haiti. The global humanitarian attempt to respon...
Although the vascular endothelial growth factor A (VEGFA) gene promoter contains an androgen response element, the link between AR signalling and angiogenesis in non-metastatic CRPC is largely unresolved [7]. Interestingly, an androgen regulation of angiogenesis has recently been described in non-...
Photoautotrophic growth response of in vitro cultured coffee plantlets to ventilation methods and photosynthetic photon fluxes under carbon dioxide enriche... Effects of two ventilation methods (forced and natural) and two photosynthetic photon fluxes (PPF, 150 and 250 μmol m−2 s−... Quynh...
Both ocean warming and acidification already have adverse consequences for marine ecosystems6. Some of the global warming impacts, however, unfold slowly in the ocean due to its large thermal and dynamical inertia. Examples are sea-level rise and the response of the Atlantic Meridional Overturning ...
