Transverse shifts and time delays of spatiotemporal vortex pulses reflected and refracted at a planar interface [PDF]

open access: yesNanophotonics, 2021
Transverse (Hall-effect) and Goos–Hänchen shifts of light beams reflected/refracted at planar interfaces are important wave phenomena, which can be significantly modified and enhanced by the presence of intrinsic orbital angular momentum (OAM) in the ...

ACCURATE SENTINEL-2 INTER-BAND TIME DELAYS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Accurate knowledge on the time-delays between detector bands is paramount for the observation of dynamic features in Sentinel-2 imagery. Sentinel-2 inter-band time delays have been characterised analytically and empirically on Level-1B images with help ...

Optical Measurement of Photorecombination Time Delays

open access: yesUltrafast Science, 2023
Recollision physics and attosecond pulse generation meld the precision of optics with collision physics. As a follow-up to our previous work, we reveal a new direction for the study of electronic structure and multielectron dynamics by exploiting the ...

Complex Dynamics of a Predator–Prey Interaction with Fear Effect in Deterministic and Fluctuating Environments

open access: yesMathematics, 2022
Many ecological models have received much attention in the past few years. In particular, predator–prey interactions have been examined from many angles to capture and explain various environmental phenomena meaningfully. Although the consumption of prey

OPTICAL-RADIO TIME DELAYS IN Q0957+561

open access: yesOdessa Astronomical Publications, 2017
Applying a specific cross-correlation method, we obtained evidence that changes in the radio flux appear to lag behind the optical variations of the quasar by about 6.4 years.

Efficient semiclassical approach for time delays

open access: yesNew Journal of Physics, 2014
The Wigner time delay, defined by the energy derivative of the total scattering phase shift, is an important spectral measure of an open quantum system characterizing the duration of the scattering event.

Incorporating Time Delays in Process Hitting Framework for Dynamical Modeling of Large Biological Regulatory Networks

open access: yesFrontiers in Physiology, 2019
Modeling and simulation of molecular systems helps in understanding the behavioral mechanism of biological regulation. Time delays in production and degradation of expressions are important parameters in biological regulation.
