NOISE EFFECTS IN POLYMER DYNAMICS [PDF]

International Journal of Bifurcation and Chaos, 2008
The study of the noise induced effects on the dynamics of a chain molecule crossing a potential barrier, in the presence of a metastable state, is presented. A two-dimensional stochastic version of the Rouse model for a flexible polymer has been adopted to mimic the molecular dynamics and to take into account the interactions between adjacent monomers.

Marine invertebrates and noise

Frontiers in Marine Science, 2023
Within the set of risk factors that compromise the conservation of marine biodiversity, one of the least understood concerns is the noise produced by human operations at sea and from land.

Low-Frequency Noise Phenomena in Switched MOSFETs [PDF]

, 2007
In small-area MOSFETs widely used in analog and RF circuit design, low-frequency (LF) noise behavior is increasingly dominated by single-electron effects.

Research on Bridge Damage Identification Based on WPE-MDS and HTF-SAPSO

Buildings, 2022
In recent decades, structural damage identification based on the wavelet analysis method has been widely developed, but it is still confronted with many difficulties, such as large decomposition error and complex data.

Newly developed aircraft routing options for air traffic simulation in the chemistry–climate model EMAC 2.53: AirTraf 2.0 [PDF]

Geoscientific Model Development, 2020
Aviation contributes to climate change, and the climate impact of aviation is expected to increase further. Adaptations of aircraft routings in order to reduce the climate impact are an important climate change mitigation measure.

Noise-Induced Phase Space Transport in Two-Dimensional Hamiltonian Systems [PDF]

, 1999
First passage time experiments were used to explore the effects of low amplitude noise as a source of accelerated phase space diffusion in two-dimensional Hamiltonian systems, and these effects were then compared with the effects of periodic driving. The

Sensitivities of atmospheric composition and climate to altitude and latitude of hypersonic aircraft emissions [PDF]

Atmospheric Chemistry and Physics
Hydrogen-powered hypersonic aircraft are designed to travel in the middle stratosphere at approximately 30–40 km. These aircraft can have a considerable impact on climate-relevant species like stratospheric water vapor, ozone, and methane and thus would ...
