LDAP directories have recently proliferated with the growth of the Internet, and are being used in a wide variety of network-based applications. In this paper, we propose the use of generalized queries, referred to as query templates, obtained by generalizing individual user queries, as the semantic basis for low overhead, high beneet LDAP directory caches for handling declarative queries. We p...

Wonderful opportunities await particle physics over the next decade, with the coming of the Large Hadron Collider to explore the 1-TeV scale (extending efforts at LEP and the Tevatron to unravel the nature of electroweak symmetry breaking) and many initiatives to develop our understanding of the problem of identity and the dimensionality of spacetime. PACS: 12.15.-y 13.85.-t 12.60.-i 14.80.Bn F...

RNA structure formation is hierarchical and, therefore, secondary structure, the sum of canonical base-pairs, can generally be predicted without knowledge of the three-dimensional structure. Secondary structure prediction algorithms evolved from predicting a single, lowest free energy structure to their current state where statistics can be determined from the thermodynamic ensemble. This artic...

Zonal separation of particles in density gradients contained in hollow or tubeless rotors has been explored with the aim of developing a preparative counterpart of the analytical ultracentrifuge. A rotor with a capacity of 1625 milliliters has been tested up to 22,500 revolutions per minute, with sucrose density gradients used. Excellent separation of subcellular particles has been achieved as ...

the paper presents the methodology for obtaining the level of noise in three-phase induction motors with squirrel cage rotor. Investigations include a single-speed motor with 3000 r/min and a two-speed motor with 750 and 1500 r/min. The investigated motors (manufactured by a Romanian company) were placed in a semi-anechoic chamber in order to determine the noise-to-frequency characteristics (sp...

An upstream manufacturer can use minimum resale price maintenance (RPM) to exclude potential competitors. RPM lets the incumbent manufacturer transfer profits to retailers. If entry is accommodated by retailers, upstream competition leads to fierce downstream competition and the breakdown of RPM. Thus, via RPM, retailers internalize the effect of accommodating entry on the incumbent’s profits. ...

The paper is devoted to the consideration of role Internet communications in political mobilization citizens. create new opportunities for interaction and association citizens significantly accelerate mobilization. In information age, "orange revolutions", other "colour revolutions" last century were replaced by high-tech "network revolutions". Among researchers, however, there no unity underst...

Joan Robinson’s association with three Cambridge ‘revolutions’—imperfect competition, effective demand and capital theory—is examined in the context of her personal and intellectual partnership with Richard Kahn, John Maynard Keynes and Piero Sraffa. Initially, imperfect competition appeared to have successfully extended marginal analysis to all market forms. It also allowed Richard Kahn and Jo...

This session described the FET Flagship Pilot on graphene and related two-dimensional materials. The flagship targets a revolution in information and communication technology, with impacts reaching into other areas of the society. The session featured four talks on the scientific and technological potential and open research challenges within the scope of the proposed flagship, industrial view ...
