It is well known that 802.11 suffers from both inefficiency and unfairness in the face of competition and interference. This paper provides a detailed analysis of the impact of topology and traffic type on network performance when two flows compete with each other for airspace. We consider both TCP and UDP flows and a comprehensive set of node topologies. We vary these topologies to consider all combinations of the following four node-to-node interactions：（1） nodes unable to read or sense each other, （2） nodes able to sense each other but not able to read each other＇s packets and nodes able to communicate with （3） weak and with （4） strong signal. We evaluate all possible cases through simulation and show that the cases can be reduced to 9 UDP and 10 TCP 802.11g models with similar efficiency/fairness characteristics. We also validate our simulation results with extensive experiments conducted in a laboratory testbed. These more detailed models improve on previous work such as hidden-/exposed-terminal categorization and are thus better suited as a basis for adaptive techniques to improve performance in 802.11 multi-hop WLAN or Mesh Networks.

The formation of crystal clusters by synneusis(magmatic sintering)affects a wide range of magmatic systems from olivine clusters in komatiite to quartz clusters in high-silica granite.A common feature of synneusis in any mineral phase is the alignment of neighbouring crystals in certain lower-energy orientation ***,the underlying mechanisms involved with both the alignment of crystals in lower-energy orientations and the binding of crystal clusters are not well *** the absence of mechanisms that bind crystals together upon contact,the same hydrodynamic forces that may bring crystals together can in theory also serve to disaggregate *** I use cathodoluminescence imaging and crystal orientation data from quartz clusters in high-silica granite to show that i)rapid crystalline neck growth along attachment surfaces and ii)grain rotation are two mechanisms that reduce the grain boundary energy of crystal clusters while increasing clusters’shear *** continued crystallization of sintered phases as the magmatic body cools further cements crystal pairs and resists cluster *** these mechanisms underpin both the formation and preservation of large crystal clusters in dynamic magmatic environments.

García-Hermoso and colleagues1 recently published a systematic literature review and meta-analysis on exercise training-induced changes in exerkine concentrations in type 2diabetes mellitus patients,providing a contemporary view on how exerkines respond to exercise *** review prompted us to highlight 2 additional considerations that should be taken into account when studying the response of exerkines to exercise ***,whether exerkines can exhibit discordant responses to acute exercise compared to exercise training,and secondly,the need to consider the residual effects of the most recent exercise bout.

The supercontinent cycle has had a profound effect on the Earth＇s evolution since the Late Archean but our understanding of the forces responsible for its operation remains *** appear to form by two end-member processes：extroversion,in which the oceanic lithosphere surrounding the supercontinent（exterior ocean） is preferentially subducted（***）,and introversion in which the oceanic lithosphere formed between dispersing fragments of the previous supercontinent（interior ocean） is preferentially subducted（***）.Extroversion can be explained by ＂top-down＂ geodynamics, in which a supercontinent breaks up over a geoid high and amalgamates above a geoid low. Introversion,on the other hand,requires that the combined forces of slab-pull and ridge push（which operate in concert after supercontinent break-up） must be overcome in order to enable the previously dispersing continents to turn *** may begin when subduction zones are initiated along boundaries between the interior and exterior oceans and become trapped within the interior *** speculate that the reversal in continental motion required for introversion may be induced by slab avalanche events that trigger the rise of superplumes from the core-mantle boundary.

The supercontinent cycle, by which Earth history is seen as having been punctuated by the episodic assembly and breakup of supercontinents, has influenced the rock record more than any other geologic phenomena, and its recognition is arguably the most important advance in Earth Science since plate tectonics. It documents fundamental aspects of the planet＇s interior dynamics and has charted the course of Earth＇s tectonic, climatic and biogeochemical evolution for billions of years. But while the widespread realization of the importance of supercontinents in Earth history is a relatively recent development, the supercontinent cycle was first proposed thirty years ago and episodicity in tectonic processes was recognized long before plate tectonics provided a potential explanation for its occurrence. With interest in the supercontinent cycle gaining momentum and the literature expanding rapidly, it is instructive to recall the historical context from which the concept developed. Here we examine the supercontinent cycle from this perspective by tracing its development from the early recognition of long-term epi- sodicity in tectonic processes, through the identification of tectonic cycles following the advent of plate tectonics, to the first realization that these phenomena were the manifestation of episodic superconti- nent assembly and breakup.

20世纪90年代之前,腹膜恶性肿瘤被认为是癌广泛转移的表现,缺乏理想治疗方法。之后,基于临床研究,国际肿瘤学界对此观念发生转变,认为部分经选择的病例,接受以肿瘤细胞减灭术(cytoreductive surgery,CRS)加腹腔热灌注化疗(hyperthermic intraperitoneal chemotherapy,HIPEC)为核心的综合治疗不但能够有效控制疾病进展,还有可能达到临床治愈。英国贝辛斯托克医院是最早开展腹膜肿瘤诊治和研究的中心之一,30余年来,在腹膜肿瘤的诊疗和国际腹膜表面恶性肿瘤学会(peritoneal surface oncology group international,PSOGI)的创立发展等领域均作出了历史性的贡献:1994年,贝辛斯托克医院在Paul H. Sugarbaker教授指导下开展了第1例CRS,目前每年完成CRS超过350例;1998年,贝辛斯托克医院主持召开了第1届PSOGI大会;建立多学科团队,发展和推广CRS+HIPEC治疗策略;制订腹膜假黏液瘤(pseudomyxoma peritonei,PMP)和恶性腹膜间皮瘤(malignant peritoneal mesothelioma,MPM)指南;开展联合CRS和多脏器移植治疗腹膜肿瘤等临床研究。贝辛斯托克是PSOGI的基础,也是PSOGI发展和延续的重要组成部分,并将取得更大进展和更为丰硕的研究成果。
