A Power Dissipation Comparison of the R-TDMA and the Slotted-Aloha Wireless MAC protocols [PDF]
, 1997 In this paper two wireless multiple-access protocols are compared by their power dissipation for the uplink traffic of a wireless networks. After briefly discussing the behaviour of the Slotted Aloha protocol (Abramson, 1985) and the R-TDMA protocol ...

Distributed Game Theoretic Optimization and Management of Multichannel ALOHA Networks [PDF]
, 2015 The problem of distributed rate maximization in multi-channel ALOHA networks is considered. First, we study the problem of constrained distributed rate maximization, where user rates are subject to total transmission probability constraints. We propose a

Diazotroph‐Driven 210Po Scavenging Reveals a Potential Radiotracer for Marine Nitrogen Fixation
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract The role of phytoplankton, particularly diazotrophs, in affecting in situ 210Po scavenging has been little investigated. Here, we first report an enhanced 210Po deficit in a cyclonic eddy core relative to its edge in the subtropical Pacific, coinciding with an elevated integrated nitrogen fixation rate (NFR).

A formal proof of the optimal frame setting for Dynamic-Frame Aloha with known population size [PDF]
, 2013 In Dynamic-Frame Aloha subsequent frame lengths must be optimally chosen to maximize throughput. When the initial population size ${\cal N}$ is known, numerical evaluations show that the maximum efficiency is achieved by setting the frame length equal to

European Eating Disorders Review, Volume 34, Issue 3, Page 845-857, May 2026.ABSTRACT Objective Perceived parental relationship characteristics, such as maternal overprotection, rejection or neglect, and peer victimisation, are suggested to be more common in patients with anorexia nervosa (AN) than in healthy controls. This study compares parental and peer relationships in adolescent patients with AN to those in a clinical ...

Optimum Header Positioning in Successive Interference Cancellation (SIC) based Aloha
, 2013 Random Access MAC protocols are simple and effective when the nature of the traffic is unpredictable and sporadic. In the following paper, investigations on the new Enhanced Contention Resolution ALOHA (ECRA) are presented, where some new aspects of the ...
