An ad hoc network is a collection of wireless hoststhat spontaneously forms a network without the use of anyexisting network infrastructure or centralized administration.Due to the limited transmission range of wireless networkinterfaces, multiple network "hops" may be needed for one node toexchange data with another node across the network. Thus,individual nodes must also act as routers. The routing problemgets complex if the nodes are mobile. Dynamic routing in the faceof topological...

The dissertation contains two components: a criticalcomponent that examines recent experiments in writing literaturespecifically for the electronic media, and a creative componentthat includes selections from The Unknown, the hypertext novel Icoauthored with William Gillespie and Dirk Stratton.

Chalcogenide glasses offer unique opportunities forbasic science and technological applications. The physicalproperties of such network-forming glasses, including theglass-forming tendency, are intimately connected to globalconnectivity of their backbones. In particular, the elasticbehavior of glasses leads to the existence ofthree distinct phasesthat appears to be generic in network forming systems. Weaklycross-linked networks are mechanically soft and formfloppy phases. Optimally cross-linked ...

Room Temperature Ionic Liquids (RTILs) comprise a newgeneration of solvents, and their exceptional properties (i.e.,non-volatility, non-flammability) promote them as alternativesolvents in applications dominated by the well-known volatileorganic compounds (VOCs). Although extensive literature existsfor ionic liquid behavior as solvents and catalysts for numerousorganic and inorganic reactions, their use for environmentalapplications is an unexplored area. Water immiscible RTILs wereselected for ...

The second Sasanian king, Shapur I, 240/2-272 CE,erected a series of triumphal monuments in southwestern Iran, themost famous of which are the rock cut reliefs depicting hisvictories over the Roman emperors Gordian III, Philip the Arab,and Valerian. The identification of the emperors has largely beenbased on their position in the reliefs and Shapur s owndescription of his interactions with the Romans in the Kaa ba-iZardusht inscription.

The Archaic Etruscan site of Acquarossa, approximately80 kilometers north of Rome, near Viterbo, contains a mid-sixthcentury monumental building complex adorned with four differenttypes of terracotta relief plaques. This complex constitutes oneof the few excavated examples of large-scale, non-funeraryarchitecture in sixth century Etruria, and there has been littleagreement as to how it functioned. Scholarly attempts to clarifythe use of the complex have been tied to the terracotta reliefplaques ...

Primordial germ cells (PGCs) are the mothers of allstem cells, capable of giving rise to every other cell in thebody. These totipotent cells are set aside early in developmentvia locational cues, and migrate to the genital ridges to formthe gonad proper. The migration process for PGCs is not overlyefficient, with PGCs migrating aberrantly throughout themigration process. The PGCs that migrate successfully into thegonadal anlagen aggregate with other PGCs, become non-motile, andcontinue to prolif...

However, the effects ofperch diameter on the limb movements of Anolis have not beenpreviously studied. Hence, ...
