Bifurcation analysis of a discrete SIS model with bilinear incidence depending on new infection by Hui Cao, Yicang Zhou, Zhien Ma

“…A discrete SIS epidemic model with the bilinear incidence depending on the new infection is formulated and studied.The condition for the global stability of the disease free equilibrium is obtained.The existence of the endemic equilibrium and its stability are investigated.More attention is paid to the existence of the saddle-node bifurcation, the flip bifurcation, and the Hopf bifurcation.Sufficient conditions for those bifurcations have been obtained.Numerical simulations are conducted to demonstrate our theoretical results and the complexity of the model.…”

Low-overhead routing algorithm for opportunistic networks based on immunity information piggybacked by SV by Zhi REN, Cong CHEN, Ya-nan CAO, Chen PENG, Qian-bin CHEN

“…A novel routing algorithm,LRPI (low-overhead routing with piggybacked immunity information) was proposed.LRPI contains the following four new mechanisms:piggybacking the immune information with SV(summary vectors),fast generation of the immune information through a cross-layer method,an improved exchange mechanism of SV,and adaptive compression of SV.Based on the above new mechanism,LRPI not only avoids using special data structure but also can achieve the same immune function more quickly.Theoretical analysis and simulation results show that LRPI outperforms the classical epidemic routing algorithm and a few of its improvements in terms of control overhead,the number of saved packets,and average end-to-end delay.…”

Research on models of network security evaluation and analysis by Wenyan LIU, Shumin HUO, Qing TONG, Miao ZHANG, Chao QI

“…Network security assessment helps to grasp the current and future risks of the network information system clearly,and gives corresponding security suggestions and countermeasures.Model of network security assessment and analysis is an important research direction and content,for which there is no review to give a comprehensive summary or analysis.A review of common network security evaluation and analysis model was given.The model that focus on attack was introduced,such as the attack tree,attack graph and kill chain,then the model that focus on network defense or offensive and defensive interaction was explained,such as attack surface,cyber epidemic model,Petri nets and automation machine,giving introduction to the basic concept,application field,modeling analysis process,advantages and disadvantages of the models.Then,typical examples were given to illustrate the application of the models in network defense technology evaluation and analysis.…”

Décoloniser la vulnérabilité : penser l’agir minoritaire des femmes d’Afrique subsaharienne dans la cause du VIH en France by Marjorie Gerbier-Aublanc

“…Deeply affected by HIV in France, Sub-Saharan African women have been thought of as a “vulnerable group”, portrayed from the homogeneous category of “third world woman” victim of men in the epidemic. Based on an empirical analysis of their mobilization in the HIV cause, this paper aims at “decolonizing the vulnerability” they are supposed to embody, by unveiling the plural forms of agency they array in this field. …”

AIDS, Caregiving and Kinship: The Queer “Family” in Bill Sherwood’s Parting Glances by Nikola Stepić

“…As a counterpoint to the emerging homonormativity of the twenty-first century, this paper seeks to identify and reevaluate the potential of queer chosen families as they are cinematically mediated, and historically located, in the context of the AIDS epidemic. With Bill Sherwood’s 1986 film Parting Glances as a case study, the paper argues that the melodramatic mode of these films, with the repetition of tropes such as caregiving, mourning and funerals, ushers an alternative mode of familiality into queer narratives and champions the queer chosen family. …”

Global analysis on a class of multi-group SEIR model with latency and relapse by Jinliang Wang, Hongying Shu

“…In this paper, we investigate the global dynamics of a multi-group SEIR epidemic model,allowing heterogeneity of the host population, delay in latency and delay due torelapsedistribution for the human population.Our results indicate that when certain restrictions on nonlinear growth rate and incidence are fulfilled, the basic reproduction number $\mathfrak{R}_0$ plays the key role of a global threshold parameter in the sense that the long-time behaviors of the model depend only on $\mathfrak{R}_0$. …”
