This paper focuses on the scalability of mobile, wireless, basestation-oriented networks. In our study of base-station networks, we investigate the performance limits and communication complexity of the protocols and services under mobility and subject to dynamic behavior of hosts and basestations. In addition, we discuss the requisite development and implementation of the base station network ...

Most models of optimal taxation with mobility deal only with real mobility, in the sense that moving out of a jurisdiction’s tax base entails a physical movement. But often escaping a jurisdiction’s tax net does not necessarily entail any physical movement, is often an avoidance (or even evasion) device, and can be accomplished by the “mere stroke of a pen.” The cost of such movement, and there...

We study the spontaneous "sliding" of histone spools (nucleosomes) along DNA as a result of thermally activated single base pair twist defects. To this end we map the system onto a suitably extended Frenkel-Kontorova model. Combining results from several recent experiments we are able to estimate the nucleosome mobility without adjustable parameters. Our model shows also how the local mobility ...

This paper presents the mobility augmentation method to provide omnidirectional mobility to nonomnidirectional wheeled bases. First, the kinematic model of a nonomnidirectional wheeled base and a link combined by an extra revolute/prismatic joint to the base is derived in a matrix-vector form. Then it is shown that, if the kinematic model satisfies some structural conditions, the link motion ca...

The in-situ observation of microstructural evolution under electron irradiation was performed in order to experimentally estimate the mobility vacancy and interstitial 316 stainless steel CoCrFeNi-base high entropy alloys. migration energy CoCrFeNiMn CoCrFeNiAl0.3 estimated be lower higher compared with that steel, respectively. While, those alloys seems almost same. increase is probably due a ...

(1) It is the Union's objective to strengthen its scientific and technological bases by achieving a European Research Area ("ERA") in which researchers, scientific knowledge and technology circulate freely, and by encouraging the Union to advance towards a knowledge society and to become a more competitive and sustainable economy in respect of its industry. To pursue that objective the Union sh...

We demonstrate that the gel electrophoretic mobility-shift assay (EMSA) can be used for site-selective and quantitative monitoring of nicks in linear double-stranded DNA (dsDNA) thus allowing to expediently follow the nicking activity of enzymes or other agents targeted to a designated dsDNA site. At elevated temperature and/or in the presence of urea, DNA fragments carrying a single nick produ...

Gel electrophoresis is the standard method to separate, identify and purify nucleic acids. SSCP detects single base changes by altered mobility of single-stranded segments electrophoresed through non-denaturing polyacrylamide gels. Herein, changes in electrophoretic mobilities due to single base substitutions were measured for single-stranded segments of lengths ranging from 333 to 547 nt. A 48...

This paper addresses the problem of base placement for mobile robots, and proposes a simple off-line solution to determine the appropriate base locations from which the robot can reach a target point. For robots with one degr~of-mobility, the feasible base locations consists of a region on the x-axis the boundaries of which are derived in the paper. The results are used to obtain the base locat...
