Effects of jet quenching on the hydrodynamical evolution of quark-gluon plasma [PDF]

open access: yes, 2006
We study the effects of jet quenching on the hydrodynamical evolution of the quark-gluon plasma (QGP) fluid created in a heavy-ion collision. In jet quenching, a hard QCD parton, before fragmenting into a jet of hadrons, deposits a fraction of its energy

Fault-Tolerant Aggregation: Flow-Updating Meets Mass-Distribution [PDF]

open access: yes, 2011
Flow-Updating (FU) is a fault-tolerant technique that has proved to be efficient in practice for the distributed computation of aggregate functions in communication networks where individual processors do not have access to global information.

A mechanistic model for minimizing pressure loss in the wellbore during drilling by considering the effects of cuttings

open access: yesFrontiers in Earth Science, 2023
Because of the existence of cuttings in the flow, the pressure loss in the wellbore can increase significantly. Minimization of the flow pressure loss greatly benefits the drilling process.

Interplay between bulk medium evolution and (D)GLV energy loss

open access: yes, 2014
We study the consistency between high-pT nuclear suppression (R_AA) and elliptic flow (v2) using Gyulassy-Levai-Vitev (GLV) energy loss or a simpler power-law dE/dL formula, for a variety of bulk evolution models.

Loss strategies for competing AIMD flows [PDF]

open access: yesComputer Networks, 2006
We study in this paper two competing AIMD flows that share a common bottleneck link. When congestion occurs, one (or both) flows will suffer a loss that will cause its throughput to decrease by a multiplicative factor. The identity of the flow that will suffer a loss is determined by a randomized "loss strategy" that may depend on the throughputs of ...
