Statistical Model of Accurately Estimating Service Delay Behavior in Saturated IEEE 802.11 Networks Based on 2-D Markov Chain

open access: yesFuture Internet, 2022
To accurately estimate the service delay behavior of IEEE 802.11 networks, this paper comprehensively considers four main factors that affect the performance of IEEE 802.11 networks and establishes a service delay model with statistical characteristics ...

Optimal Compression and Transmission Rate Control for Node-Lifetime Maximization [PDF]

open access: yes, 2018
We consider a system that is composed of an energy constrained sensor node and a sink node, and devise optimal data compression and transmission policies with an objective to prolong the lifetime of the sensor node.

Research of real-time adaptive scheduling algorithm for across segments delay in EPA

open access: yesGong-kuang zidonghua, 2013
In view of problem that EPA network only supports real-time data transmission inside segments but not across segments, a real-time adaptive scheduling algorithm for across segments delay in EPA was proposed. Transmission process of across segments in EPA

Enhancement of transmission quality in soliton-based optical waveguide systems by frequency dependent linear gain-loss and the Raman self-frequency shift [PDF]

open access: yesPhys. Rev. A 98, 013853 (2018), 2018
We study transmission stabilization against radiation emission in soliton-based nonlinear optical waveguides with weak linear gain-loss, cubic loss, and delayed Raman response. We show by numerical simulations with perturbed nonlinear Schr\"odinger propagation models that transmission quality in waveguides with frequency independent linear gain and ...

Adaptive Network Coding Schemes for Satellite Communications

open access: yes, 2016
In this paper, we propose two novel physical layer aware adaptive network coding and coded modulation schemes for time variant channels. The proposed schemes have been applied to different satellite communications scenarios with different Round Trip ...

Long non‐coding RNAs as therapeutic targets in head and neck squamous cell carcinoma and clinical application

open access: yesFEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

Performance Analysis of a System with Bursty Traffic and Adjustable Transmission Times

open access: yes, 2018
In this work, we consider the case where a source with bursty traffic can adjust the transmission duration in order to increase the reliability. The source is equipped with a queue in order to store the arriving packets.

Exploring surface‐guided systems for intelligent breathing‐adapted four‐dimensional computed tomography: A comparison to infrared‐based reflective marker systems

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study evaluates the technical feasibility of adapting a surface monitoring system, designed for conventional four‐dimensional computed tomography (4DCT), to an intelligent, breathing‐adapted 4DCT and examines its potential to expand the currently limited range of supported surrogate systems.
