This paper investigates the achievable rates using variable length codes when transmitting independent informationover a degraded broadcast channel. In this note, we define the transmission rates from the perspective of the receivers and allow the decoders ...
Fountain codes are currently employed for reliable and efficient transmission of information via erasure channels with unknown erasure rates. This correspondence introduces the notion of fountain capacity for arbitrary channels. In contrast to the conventi ...
Distributed Video Coding (DVC) is a new paradigm in video coding, based on the Slepian-Wolf and Wyner-Ziv theorems. DVC offers a number of potential advantages: flexible partitioning of the complexity between the encoder and decoder, robustness to channel ...
In this paper, we present near-field optical images of nanostructures exhibiting an extraordinary transmission. These structures consist of annular aperture arrays engraved in a metallic film: they are quite promising structures for nanophotonics because o ...
Several pathogens - bacteria, viruses and parasites - must enter mammalian cells for survival, replication and immune-system evasion. These pathogens generally make use of existing cellular pathways that are designed for nutrient uptake, receptor downregul ...
We experimentally measure and theoretically model the light transmission characteristics of subwavelength apertures. The characterization consists of translating a point source at varying vertical height and lateral displacement from the aperture and measu ...
10-Gb/s modulation speed and transmission over 10-km SM fiber with BER < 10(-11) up to 100 degrees C temperature are achieved with optimized wafer-fused GaAs/AlGaAs-InP/InAlGaAs VCSELs incorporating re-grown tunnel junction. These VCSELs operate in the 131 ...
We address the problem of distributed compression in acoustic sensor networks. A typical scenario consists of a set of microphones that record a sound source located at some unknown position. The goal then is to convey the corresponding audio signals to a ...
Afin de concevoir et développer un ensemble d’instruments chirurgicaux ultrasoniques permettant de découper ou enlever du tissu humain, du cartilage, des os et surtout, des disques intervertébraux, plusieurs méthodes de transmission et amplification du mou ...
In silico analysis reveals that most protective antigens expressed by the antituberculous vaccine Mycobacterium bovis BCG (BCG) are conserved in M. avium, supporting the hypothesis that exposure to environmental mycobacteria generates cross-reactive immune ...
