Recently, it has been shown that CSMA-type random access algorithms can achieve the maximum possible throughput in ad hoc wireless networks. However, these assume an idealized continuous-time CSMA protocol where collisions never occur. In addition, simulation results indicate delay performance of be quite bad. On other hand, although some simple heuristics (such as distributed approximations greedy maximal scheduling) yield much better for a large set arrival rates, they may only fraction...
Ferroptosis is a recently discovered pathway for regulated cell death pathway. However, its efficacy affected by limited iron content and intracellular ion homeostasis. Here, we designed metal-organic framework (MOF)-based nanoplatform that incorporates calcium peroxide (CaO
Due to its low complexity, Greedy Maximal Scheduling (GMS), also known as Longest Queue First (LQF), has been studied extensively for wireless networks. However, GMS can result in degraded throughput performance general In this paper, we prove that achieves 100% all networks with eight nodes or less, under the two-hop interference model. Further, obtain bounds improve upon previous results larger up a certain size. We provide simple proof show be implemented using only local neighborhood...

Markov decision process (MDP) tools applied to analyze compute the optimal CAC policy that optimizes certain performance metrics system. But for most practical systems, it prohibitively difficult using any MDP algorithm because "curse dimensionality". We are, therefore, motivated consider two families structured...
Submarine landslides are inherently difficult to detect, complicating the timely issuance of disaster warnings and rapid risk assessments.

Blockchain technology has given rise to a series of new blockchain online social media (BOSMs), which Steemit is representative. Such communities are based on token reward system and attempt engross users in the knowledge activities community through payment. Studies have found that such been abused (e.g., collusion for profit), but few studies performed an in-depth analysis this phenomenon. Consequently, real data used as case study herein examine BOSMs. Two user behaviors (group-voting...
