Variable heavy tails in Internet traffic [PDF]
Performance Evaluation, 2004 This paper studies tails of the size distribution of Internet data flows and their "heaviness". Data analysis motivates the concepts of moderate, far and extreme tails for understanding the richness of information available in the data. The data analysis also motivates a notion of "variable tail index", which leads to a generalization of existing ...

Achievable Performance of Blind Policies in Heavy Traffic [PDF]
Mathematics of Operations Research, 2018 For a GI/GI/1 queue, we show that the average sojourn time under the (blind) Randomized Multilevel Feedback algorithm is no worse than that under the Shortest Remaining Processing Time algorithm times a logarithmic function of the system load. Moreover, it is verified that this bound is tight in heavy traffic, up to a constant multiplicative factor ...

Heavy-traffic limits for nearly deterministic queues [PDF]
ACM SIGMETRICS Performance Evaluation Review, 2010 We establish heavy-traffic limits for "nearly deterministic" queues, such as the G/D/n many-server queue. Waiting times before starting service in the G/D/n queue are equivalent to waiting times in an associated Gn/D/ 1 model, where the G

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
