    Efficient low-delay routing algorithm for opportunistic networks based on cross-layer sensing of encountered nodes by Zhi REN, Jian-wei SUO, Hong CHEN, Zhong-hao XU, Qian-bin CHEN

    Published 2013-10-01
    “…An efficient low-delay routing algorithin,name epidemic routing based on cross-layer encountered-node sens-ing (ERCES)was proposed to address the issue that the epidemic-based routing algorithms have some extralatency in sensing encountered nodes and extra overhead in exchanging data packets.ERCES achieves to speed sensing encountered nodes through cross-layer design among the PHY,MAC,and network layers.Moreover,to reduce overhead and to de-crease data latency,it makes a node send novel data packet immediately after encountering other nodes,sends the packets close-by their destinations firstly after receiving summary vector(SV)packets,adaptively varies the period of HELLO packets and deletes the packets reaching their destinations from nodes' memory with the help of SVs.Theoretical anal-,ysis verifies the effectiveness of ERCES.And simulation results show that ERCES reduces by at least 11.3% the control overhead by at least 8.2%,2.1% memory overhead by more than 2.1%,and the average end-to-end delay by at least 11.3%.…”

    A hybrid data assimilation method based on real-time Ensemble Kalman filtering and KNN for COVID-19 prediction by SongTao Zhang, LiHong Yang

    Published 2025-01-01
    “…Abstract This study introduces a hybrid data assimilation method that significantly improves the predictive accuracy of the time-dependent Susceptible-Exposed-Asymptomatic-Infected-Quarantined-Removed (SEAIQR) model for epidemic forecasting. The approach integrates real-time Ensemble Kalman Filtering (EnKF) with the K-Nearest Neighbors (KNN) algorithm, combining dynamic real-time adjustments with pattern recognition techniques tailored to the specific dynamics of epidemics. …”

    Assessment of the impacts of public health and social measures on influenza activity during the COVID-19 pandemic from 2020 to 2022 in Beijing, China: a modelling study by Jing Du, Lei Jia, Yanlin Gao, Jianting Su, Chao Wang, Xinghuo Pang, Gang Li

    Published 2025-01-01
    “…The simulation shows that strict PHSMs effectively suppressed the current flu epidemic effectively. When susceptible individuals drop to 50%, a relaxed strategy results in a smaller rebound in the next flu season, with epidemic sizes increasing to 1.18 (1.10, 1.30), 1.41 (1.20, 1.54), and 1.54 (1.35, 1.55) for relaxed, moderate, and strict measures, respectively. …”

    Spatial risk modelling of highly pathogenic avian influenza in France: Fattening duck farm activity matters. by Jean Artois, Timothée Vergne, Lisa Fourtune, Simon Dellicour, Axelle Scoizec, Sophie Le Bouquin, Jean-Luc Guérin, Mathilde C Paul, Claire Guinat

    Published 2025-01-01
    “…In this study, we present a comprehensive analysis of the key spatial risk factors and predictive risk maps for HPAI infection in France, with a focus on the 2016-17 and 2020-21 epidemic waves. Our findings indicate that the most explanatory spatial predictor variables were related to fattening duck movements prior to the epidemic, which should be considered as indicators of farm operational status, e.g., whether they are active or not. …”
