Minimum Expected Distortion in Gaussian Source Coding with Fading Side Information

open access: yes, 2012
An encoder, subject to a rate constraint, wishes to describe a Gaussian source under squared error distortion. The decoder, besides receiving the encoder's description, also observes side information consisting of uncompressed source symbol subject to ...

Finite-horizon H∞ control for discrete time-varying systems with randomly occurring nonlinearities and fading measurements [PDF]

open access: yes, 2015
This technical note deals with the H∞ control problem for a class of discrete time-varying nonlinear systems with both randomly occurring nonlinearities and fading measurements over a finite-horizon. The system measurements are transmitted through fading

Level Crossing Rate of Macrodiversity System in the Presence of Multipath Fading and Shadowing [PDF]

open access: yes, 2015
Macrodiversity system including macrodiversity SC receiver and two microdiversity SC receivers is considered in this paper. Received signal experiences, simultaneously, both, long term fading and short term fading.

Quantification of Modifiers Fading during Melt Holding in the Aluminum Casting Furnace

open access: yesCrystals, 2023
Strontium (Sr) and sodium (Na) are the most used modifiers in the aluminum casting industry. Both lose their concentration (fade) during holding in the melting furnace.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Characterization of Radio Signal Strength Fluctuations in Road Scenarios for Cellular Vehicular Network Planning in LTE

open access: yesIEEE Access, 2021
Road coverage will be a key issue for the success of connected car applications. In this work, a comprehensive analysis of radio signal strength fluctuations on roads in a Long Term Evolution (LTE) system is presented.

Optimum Pilot Overhead in Wireless Communication: A Unified Treatment of Continuous and Block-Fading Channels

open access: yes, 2009
The optimization of the pilot overhead in single-user wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interest (e.g., fading rate, signal-to-noise ratio) is quantified.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.
