In role-based access control (RBAC) permissions are associated with roles, and users are made members of appropriate roles thereby acquiring the roles' permissions. The principal motivation behind RBAC is to simplify administration. An appealing possibility is to use RBAC itself to manage RBAC, to further provide administrative convenience. In this paper we introduce a role-based administrative...

The challenge in massive Machine Type Communication (mMTC) is to support reliable and instant access for an enormous number of machine-type devices (MTDs). In some particular applications mMTC, the point (AP) only has know messages received, but not where they source from, thus giving rise concept unsourced random (URA). this paper, we propose a novel URA scheme exploiting elegant properties Re...

Two linkage groups were established in Bacillus pumilus NRRL B-3275 by bacteriophage PBS1 transduction. Group L contains the auxotrophic markers gly, his, and met. Group M contains the markers argO, met, ura, and cys.

Linear connections are introduced on a series of noncommutative geometries which have commutative limits. Quasicommutative corrections are calculated. LPTHE Orsay 95/42; ESI Vienna 235 * Laboratoire associé au CNRS URA D0063

The transport properties of an ionic model for liquid silica [1] at high temperatures and pressure are investigated using molecular dynamics simulations. With increasing pressure, a clear change from ”strong” to ”fragile” behaviour (according to Angell’s classification of glass-forming liquids) is observed, albeit only on the small viscosity range that can be explored in MD simulations. This ch...

The ability to conveniently construct gene disruptions is an important methodology for genetic analysis of the fission yeast Schizosaccharomyces pombe. Because of the limited number of selectable markers available for generating gene disruptions in fission yeast, the construction of strains that contain multiple gene disruptions can be quite difficult. This becomes a particular problem when epi...

In this paper, we propose a method whi h utilizes a probabilisti language model in nonfa toid type question-answering system in order to improve its a ura y. The model is a mixture probabilisti language model of partof-spee h and surfa e expressions. We introdu ed the model into two sub-pro esses whi h al ulate similarity of texts in terms of writing style. The rst pro ess olle ts example quest...

This paper presents a synoptic account of verbal suffixation in the Ura dialect Bumthang, language central Bhutan. Examining allomorphy shows persistence exceptions to historical sound changes contemporary allophonic and allomorphic processes, reveals striking contrasts with culturally dominant Tibetic languages area. We examine ways which some is motivated by patterns seen phonology more widel...
