On the Interplay between Entropy and Robustness of Gene Regulatory Networks

open access: yesEntropy, 2010
The interplay between entropy and robustness of gene network is a core mechanism of systems biology. The entropy is a measure of randomness or disorder of a physical system due to random parameter fluctuation and environmental noises in gene regulatory ...

Diffusion in Phase Space as a Tool to Assess Variability of Vertical Centre-of-Mass Motion during Long-Range Walking

open access: yesPhysics, 2023
When a Hamiltonian system undergoes a stochastic, time-dependent anharmonic perturbation, the values of its adiabatic invariants as a function of time follow a distribution whose shape obeys a Fokker–Planck equation.

RPM - the fast Random Particle-Mesh method to realize unsteady turbulent sound sources and velocity fields for CAA applications. [PDF]

open access: yes, 2007
The simulation of broadband noise with CAA techniques is discussed. Unsteady broadband sound sources are modeled in the time-domain with a highly efficient computational method.

Trailing-edge noise reduction of a wing by a surface modification [PDF]

open access: yes, 2021
There is an increased emphasis on reducing airframe noise in the last decades. Airframe noise is sound generated by the interaction of a turbulent flow with the aircraft geometry, and significantly contributes to the overall noise production during the ...

Novel readout circuit architecture for CMOS image sensors minimizing RTS noise [PDF]

open access: yes, 2011
This letter presents a novel readout architecture and its associated readout sequence for complementary metal–oxide– semiconductor (CMOS) image sensors (CISs) based on switch biasing techniques in order to reduce noisy pixel numbers induced by in-pixel

Slat Noise Prediction using Discontinuous Galerkin Method and Stochastic Turbulent Sound Source [PDF]

open access: yes, 2010
A promising way to predict airframe noise is the numerical solution of the Acoustic Perturbation Equations (APE) with the help of the Discontinuous Galerkin Method (DGM) and the Fast Random Particle Mesh (FRPM) method.

Custom transistor layout design techniques for random telegraph signal noise reduction in CMOS image sensors [PDF]

open access: yes, 2010
Interface and near oxide traps in small gate area MOS transistors (gate area ,1 mm2) lead to RTS noise which implies the emergence of noisy pixels in CMOS image sensors.
