Optimizing Information Freshness in a Multiple Access Channel With Heterogeneous Devices

open access: yesIEEE Open Journal of the Communications Society, 2021
In this work, we study age-optimal scheduling with stability constraints in a multiple access channel with two heterogeneous source nodes transmitting to a common destination.

A Jamming-Resilient and Scalable Broadcasting Algorithm for Multiple Access Channel Networks

open access: yesApplied Sciences, 2021
Multiple access channel (MAC) networks use a broadcasting algorithm called the Binary Exponential Backoff (BEB) to mediate access to the shared communication channel by competing nodes and resolve their collisions.

Dynamic sharing of a multiple access channel

open access: yesCoRR, 2010
In this paper we consider the mutual exclusion problem on a multiple access channel. Mutual exclusion is one of the fundamental problems in distributed computing. In the classic version of this problem, n processes perform a concurrent program which occasionally triggers some of them to use shared resources, such as memory, communication channel ...

Novel half-duplex relay strategy and its resource allocation

open access: yesTongxin xuebao, 2009
Conventional time-division half-duplex relay strategies based on amplify-and-forward or decode-and-forward strategy could relieve relay nodes from full-duplex requirement but lead to degraded spectrum efficiency.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

ZF-SIC Based Individual Secrecy in SIMO Multiple Access Wiretap Channel

open access: yesIEEE Access, 2017
In this paper, a decoding method of joint zero-forcing and successive interference cancellation (ZF-SIC) is put forward to assist the study of the individual secrecy in the quasi-static Rayleigh fading single-input multiple-output multiple access wiretap

Coding for a multiple-access channel

open access: yesInformation and Control, 1978
The channel considered here is a real-number adder. Attention is restricted to the case of two sources using binary signals; hence the channel has a ternary output. The paper treats both the noiseless and noisy situations. For the noiseless case the following results are obtained: several code-construction techniques are presented; a Gilbert-like lower

Asynchronous multiple-access channel capacity [PDF]

open access: yesIEEE Transactions on Information Theory, 1981
The capacity region for the discrete memoryless multiple-access channel without time synchronization at the transmitters and receivers is shown to be the same as the known capacity region for the ordinary multiple-access channel. The proof utilizes time sharing of two optimal codes for the ordinary multiple-access channel and uses maximum likelihood ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
