Chronic wounds caused by bacterial infections are a major challenge in medical fields. The hypoxia condition extremely induces reactive oxygen species (ROS) generation and upregulates the expression of hypoxia‐inducible factor, both of which can increase the pro‐inflammatory M1 subtype macrophages production while reducing the anti‐inflammatory M2 subtype macrophages. Besides, bacteria‐formed biofilms...
In vehicular ad hoc networks, the basic safety message (BSM) is periodically broadcast by every vehicle on the road. By exchanging BSMs with neighbors, vehicles aggregate the collected information to get aware of driving environment and react promptly in case of any danger. The BSM dissemination is particularly crucial for vehicles at urban road intersections to avoid car collisions. However, blocking...
Road Side Units (RSUs)-based data communication (V2I) is an increasingly popular technique in vehicular networks to alleviate the frequent vehicle-to-vehicle (V2V) communication problem. On-demand broadcasting is a scalable approach for supporting large clients with dynamic demands. However, the performance of the traditional on-demand broadcast can be improved significantly with the incorporation...
Basic safety message(BSM) or heartbeat message is periodically broadcast by each vehicle on the road, conveying vehicle's instantaneous position and driving state. The vehicular communication network enables the fast exchange of BSMs with neighboring vehicles which assists drivers in acquiring the local driving environment and maneuvering promptly in case of any potential hazard. Such message is exceptionally...
Network coding has become increasingly popular in time efficient data dissemination due to its inherent nature of broadcasting multiple data items in encoded form through a single broadcast. However, not much attention has been put forth on the efficiency of network coding when accessed data items' sizes can vary. In this work, we have investigated that when clients' accessed data items are of different...
The vulnerability of power grid is a key issue with large blackouts, causing power supply to be halted for millions. With a special touch on power grid of Singapore, this study aims to provide practical and effective protection schemes to enhance grid robustness against cascading failure caused by intentional or unintentional attack. Power grid distinguishes itself from other networks like traffic...
Sixteen conventional heart beat variability (HRV) parameters and eight vital signs have shown promise in the prediction of cardiac arrest within 72 hours. Besides these 24 parameters, we proposed adding two new features for cardiac arrest prediction, which are approximate entropy (ApEn) and sample entropy (SpEn). ApEn and SpEn are nonlinear HRV parameters capable of characterizing heart conditions...
