Age of Information in Downlink Systems: Broadcast or Unicast Transmission? [PDF]

, 2022
We analytically decide whether the broadcast transmission scheme or the unicast transmission scheme achieves the optimal age of information (AoI) performance of a multiuser system where a base station (BS) generates and transmits status updates to multiple user equipments (UEs).

Transmission of Population-Coded Information [PDF]

Neural Computation, 2012
As neural activity is transmitted through the nervous system, neuronal noise degrades the encoded information and limits performance. It is therefore important to know how information loss can be prevented. We study this question in the context of neural population codes.

Evaluation of an EPID in vivo monitoring system using local and external independent audit measurements

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The aim of this work was to evaluate the SunCHECK PerFRACTION, the software for in vivo monitoring using EPID images. Materials/Methods First, the PerFRACTION ability to detect errors was investigated simulating two situations: (1) variation of LINAC output and (2) variation of the phantom thickness.

Comparative genomics and evolution of regulons of the LacI-family transcription factors

Frontiers in Microbiology, 2014
DNA-binding transcription factors (TFs) are essential components of transcriptional regulatory networks in Bacteria. LacI-family TFs (LacI-TFs) are broadly distributed among certain lineages of bacteria. The majority of characterized LacI-TFs sense sugar

Modeling of Real-Time Multimedia Streaming in Wi-Fi Networks With Periodic Reservations

IEEE Access, 2020
An important problem of modern Wi-Fis is the interferences caused by hidden stations active in the same area, or in multihop communications. All these issues significantly degrade the efficiency of the random channel access methods.

Competitive Screening and Information Transmission [PDF]

SSRN Electronic Journal, 2017
AbstractWe consider a model in which schools and colleges compete for high‐ability students, which are independently identified through a costly screening procedure. This independence creates a channel through which students' preferences affect the strategic interaction between schools: students with competing offers accept the most‐preferred one ...
