A methodological approach to BISDN signalling performance [PDF]
, 1994 Sophisticated signalling protocols are required to properly handle the complex multimedia, multiparty services supported by the forthcoming BISDN. The implementation feasibility of these protocols should be evaluated during their design phase, so that ...

International Journal of Finance &Economics, EarlyView.ABSTRACT This study examines the impact of corporate COVID‐19 disclosure on the negative tone (pessimism) in annual reports. We also investigate how board size and board independence influence pessimism in annual reports. Using a U.K. sample from 2020, we employ various techniques to explore the COVID‐19 disclosure‐pessimism nexus.

InfoMat, EarlyView.Leveraging the modulation effect of oxygen vacancies on the energy barrier, a homogeneously integrated all‐PRC system with tunable temporal dynamics is constructed. The broad range ratio of temporal characteristic (>102) of the reservoir enables PRC to process information across multi‐timescale.

Efficient and robust fiber coupling of superconducting single photon detectors [PDF]
arXiv, 2011 We applied a recently developed fiber coupling technique to superconducting single photon detectors (SSPDs). As the detector area of SSPDs has to be kept as small as possible, coupling to an optical fiber has been either inefficient or unreliable. Etching through the silicon substrate allows fabrication of a circularly shaped chip which self aligns to ...

Ultralow Photon Flux OWC Links Using UV‐C Single‐Photon Detection
Laser &Photonics Reviews, EarlyView.This work presents ultralow photon flux UV‐C optical wireless communication (OWC) links using a micro‐LED and a silicon photomultiplier (SiPM)‐based single‐photon detector (SPD). A record‐low transmission of 7.7 photons per bit and a maximum data rate of 120 Mbit s−1 are achieved. Furthermore, single‐photon links highlight the potential for a future UV‐

A Full Characterization of Irrelevant Components in Diameter Constrained Reliability [PDF]
arXiv, 2014 In classical network reliability analysis, the system under study is a network with perfect nodes but imperfect link, that fail stochastically and independently. There, the goal is to find the probability that the resulting random graph is connected, called \emph{reliability}. Although the exact reliability computation belongs to the class of $\mathcal{

Nucleation and Propagation of Traveling Charge Domains in a Planar AlGaN/GaN Triode Structure
physica status solidi (a), EarlyView.This work presents a novel model for the nucleation of charge domain instabilities in semiconductors exhibiting negative differential drift velocity, identifying diffusion as the key factor inhibiting domain formation. A planar Gunn triode structure is proposed which overcomes obstacles to the realization of GaN‐based Gunn effect devices with ...

Coded Caching Clusters with Device-to-Device Communications [PDF]
arXiv, 2016 We consider a geographically constrained caching community where popular data files are cached on mobile terminals and distributed through Device-to-Device (D2D) communications. Further, to ensure availability, data files are protected against user mobility, or churn, with erasure coding.
