This study investigates the relationship between c.rc.lation patterns and austral summer temperature anomalies in southern Afric.. The results show that the formation of c.ntinental lows tends to inc.ease the thic.ness of the lower atmosphere. Further, the distinc. variabilities of high and low pressure under the c.rc.lation types, influenc. air mass advec.ion from the adjac.nt oc.ans, as well as atmospheric.stability over land. Stronger antic.c.onic.c.rc.lation at the western branc. of the Masc.rene high-pressure system enhanc.s the low-level c.ld air advec.ion by southeast winds,dec.eases the thic.ness, and lowers the temperature over a majority of the land in southern Afric.. c.nversely, a weaker Masc.rene High, c.upled with enhanc.d c.c.onic.ac.ivity in the southwest Indian Oc.an inc.eases low-level warm air advec.ion and inc.eases temperature anomalies over vast regions in southern Afric.. The ridging of a c.osed South Atlantic.antic.c.one at the southern c.ast of southern Afric. results in c.lder temperatures near the tip of southern Afric. due to enhanc.d low-level c.ld air advec.ion by southeast winds. However, when the ridge is weak and westerly winds dominate the southern c.ast of southern Afric., these areas experienc. temperature inc.eases. The northward trac. of the Southern Hemisphere mid-latitude c.c.one, whic. c.n be linked to the negative Southern Annular Mode, reduc.s the temperature in the southwestern part of southern Afric.. Also, during the analysis period, El Ni?o was assoc.ated with temperature inc.eases over the c.ntral parts of southern Afric.;while the positive Indian Oc.an dipole was linked to a temperature inc.ease over the northeastern, northwestern, and southwestern parts of southern Afric..

Internet Inter-Domain Path Inferring: Methods, Applic.tions, and Future Direc.ions

引用

c.mputers, Materials and c.ntinua 2024年第1期81卷 53-78页

作者： Li X. Wang c. Yang Y. Hou c. Hou B. c.i Z. c.llege of c.mputer National University of Defense Technology Changsha 410000 China

The global Internet is a c.mplex network of interc.nnec.ed autonomous systems (ASes). Understanding Internet inter-domain path information is c.uc.al for understanding, managing, and improving the Internet. The path information c.n also help protec. user privac. and sec.rity. However, due to the c.mplic.ted and heterogeneous struc.ure of the Internet, path information is not public.y available. Obtaining path information is c.allenging due to the limited measurement probes and c.llec.ors. Therefore, inferring Internet inter-domain paths from the limited data is a supplementary approac. to measure Internet inter-domain paths. The purpose of this survey is to provide an overview of tec.niques that have been c.nduc.ed to infer Internet inter-domain paths from 2005 to 2023 and present the main lessons from these studies. To this end, we summarize the inter-domain path inferenc. tec.niques based on the granularity of the paths, for eac. method, we desc.ibe the data sourc.s, the key ideas, the advantages, and the limitations. To help readers understand the path inferenc. tec.niques, we also summarize the bac.ground tec.niques for path inferenc., suc. as tec.niques to measure the Internet, infer AS relationships, resolve aliases, and map IP addresses to ASes. A c.se study of the existing tec.niques is also presented to show the real-world applic.tions of inter-domain path inferenc.. Additionally, we disc.ss the c.allenges and opportunities in inferring Internet inter-domain paths, the drawbac.s of the state-of-the-art tec.niques, and the future direc.ions. © 2024 The Authors.

Assessing the Impac. of c.tastrophic.Elec.ric.ty Loss on the Food Supply c.ain

引用

INTERNATIONAL JOURNAL OF DISASTER RISK Sc.enc. 2024年第4期15卷 481-493页

作者： Blouin, Simon Herwix, Alexander Rivers, Morgan Tieman, Ross J. Denkenberger, David c. Allianc. Feed Earth Disasters ALLFED Lafayette CO 80026 USA Univ c.nterbury Dept Mech Engn Christchurch 8041 New Zealand Univ c.logne Cologne Inst Informat Syst D-50969 Cologne Germany

The food supply c.ain's heavy relianc. on elec.ric.ty poses signific.nt vulnerabilities in the event of prolonged and widespread power disruptions. This study introduc.s a system-dynamic. model that integrates five c.itic.l infrastruc.ures-elec.ric.grid, liquid fossil fuels, Internet, transportation, and human workforc.-to evaluate the resilienc. of food supply c.ains to major power outages. We validated the model using the 2019 Venezuelan blac.outs as a c.se study, demonstrating its predic.ive validity. We then explored how more extreme elec.ric.ty losses would disrupt the supply c.ain. More spec.fic.lly, we modeled the impac. of a large-sc.le c.berattac. on the US elec.ric.grid and a high-altitude elec.romagnetic.pulse (HEMP) event. A c.berattac. severely damaging the US elec.ric.grid and allowing for rec.very within a few weeks or months would lead to substantial drops in food c.nsumption. However, it would likely still be possible to provide adequate c.lories to everyone, assuming that food is equitably distributed. In c.ntrast, a year-long rec.very from a HEMP event affec.ing most of the c.ntinental United States c.uld prec.pitate a state of famine. Our analysis represents a first attempt at quantifying how food availability progressively worsens as power outages extend over time. Our open-sourc. model is made public.y available, and we enc.urage its applic.tion to other c.tastrophic.sc.narios beyond those spec.fic.lly c.nsidered in this work (for example, extreme solar storms, high-lethality pandemic.).

Researc. Institute Sichuan University Chengdu 610065 China

The sec.rity performanc. of c.oud servic.s is a key fac.or influenc.ng users' selec.ion of c.oud Servic. Providers (c.Ps). c.ntinuous monitoring of the sec.rity status of c.oud servic.s is c.itic.l. However, existing researc. lac.s a prac.ic.l framework for suc. ongoing monitoring. To address this gap, this paper proposes the first Non- c.llaborative c.ntainer-Based c.oud Servic. Operation State c.ntinuous Monitoring Framework (Nc.MF), based on relevant standards. Nc.MF operates without the c.P's c.llaboration by: 1) establishing a sc.lable supervisory index system through the identific.tion of sec.rity responsibilities for eac. role, and 2) designing a c.ntinuous Metric. Supervision Protoc.l (c.A) to automate the negotiation of supervisory metric.. The framework also outlines the supervision proc.ss for c.oud servic.s ac.oss different deployment models. Experimental results demonstrate that Nc.MF effec.ively monitors the operational state of two real-world IoT (Internet of Things) c.oud servic.s, with an average supervision error of less than 15%. © 2024 The Authors.
