Interplay between single-stranded binding proteins on RNA secondary structure

open access: yes, 2013
RNA protein interactions control the fate of cellular RNAs and play an important role in gene regulation. An interdependency between such interactions allows for the implementation of logic functions in gene regulation.

Simultaneous Perfect Anomalous Reflection and Angle of Arrival Sensing in Reconfigurable Intelligent Surfaces

open access: yesAdvanced Optical Materials, Volume 13, Issue 13, May 5, 2025.
A reconfigurable intelligent surface is proposed that can simultaneously anomalously reflect the light and sense the angle of arrival. An in situ optimization of either the currents flowing on array elements or the far field in the receiver direction realizes anomalous reflection and suppresses parasitic scattering.

Selenium Nucleophilicity and Electrophilicity in the Intra‐ and Intermolecular SN2 Reactions of Selenenyl Sulfide Probes

open access: yesChemistry – A European Journal, Volume 31, Issue 12, February 25, 2025.
Chalcogenol‐dichalcogenide exchange reactions of linear and cyclic dichalcogenides are investigated in silico to gain insight into their relative rates. The unveiled role of double exchange reactions in the chemistry of RX1, a selenenyl sulfide TrxR1 probe, explains the origin of its specificity even under high‐thiol concentrations and provides hints ...

Motional frequency shifts of trapped ions in the Lamb-Dicke regime

open access: yes, 2007
First order Doppler effects are usually ignored in laser driven trapped ions when the recoil frequency is much smaller than the trapping frequency (Lamb-Dicke regime).

Complete Mode Spectrum Decomposition of Complex‐Structured Light by Computer‐Generated Holography

open access: yesAdvanced Photonics Research, Volume 6, Issue 2, February 2025.
In this article, a new optical method based on self‐interference is proposed to completely decompose the eigenmode spectrum of complex‐structured light. A diffractive optical method is designed and validated to extract the complete information of complex‐structured light fields composed with eigenmode superposition states, including the order of ...

Lensing by Kerr Black Holes. II: Analytical Study of Quasi-Equatorial Lensing Observables

open access: yes, 2011
In this second paper, we develop an analytical theory of quasi-equatorial lensing by Kerr black holes. In this setting we solve perturbatively our general lens equation with displacement given in Paper I, going beyond weak-deflection Kerr lensing to ...

Machine Learning Prediction of Tritium‐Helium Groundwater Ages in the Central Valley, California, USA

open access: yesWater Resources Research, Volume 61, Issue 1, January 2025.
Abstract Groundwater ages provides insight into recharge rates, flow velocities, and vulnerability to contaminants. The ability to predict groundwater ages based on more accessible parameters via Machine Learning (ML) would advance our ability to guide sustainable management of groundwater resources.

A stochastic model for quantum measurement

open access: yes, 2013
We develop a statistical model of microscopic stochastic deviation from classical mechanics based on a stochastic processes with a transition probability that is assumed to be given by an exponential distribution of infinitesimal stationary action.

Adaptive fuzzy gain scheduling PID controller for frequency regulation in modern power system

open access: yesIET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Abstract Here an adaptive fuzzy gain scheduling proportional, integral and derivative (FGPID) controller has been proposed for the load frequency control of a three‐area inter‐connected modern power system with the large‐scale wind‐power penetration in the presence of the vehicle‐to‐grid.
