A two stage position-sensitive gas proportional counter has been constructed by tightly coupling a Gas Electron Multiplier (GEM) with a Micro-Groove Detector (MGD). The GEM was used as the first amplifying stage and was optimised to transmit close to 100 % of the primary charge even at very high drift fields (10 kV/cm). Very narrow GEM– MGD separations (0–600 m) were used so that the active vol...

In this paper we review the hole argument for the space-time points and elementary particles and we discuss the problem concerning the individuation of the objects in more general settings such that fiber manifolds, natural bundles and local diffeomorphisms, and fibered sets and n-ary relations. ∗Department of Physics and Center for Einstein Studies, Boston University †Department of Mathematics...

It is a common observation that complex systems have a nested or hierarchical structure: they consist of subsystems, which themselves consist of subsystems, and so on, until the simplest components we know, elementary particles. It is also generally accepted that the simpler, smaller components appeared before the more complex, composite systems. Thus, evolution tends to produce more complex sy...

We make use of the well-known properties of spontaneous decays of stationary states of bound systems of elementary particles to support the view that the forces which form these systems propagate instantaneously at the moment of their decay.

Supersymmetric (SUSY) standard models in which the lightest SUSY particle (LSP) is an ultralight gravitino (m3/2 = O(1) eV) are very attractive, since they are free from the cosmological gravitino problems. If the neutralino is the next lightest SUSY particle (NLSP), it decays into a photon and the gravitino in collider experiments. We propose a simple test for the lightness of gravitino at the...

background and aims: virus-like particles (vlps) have been suggested to be a promising recombinant vaccine approach. several studies have reported that the influenza vlps produced in insect cells is an effective vaccine candidate. due to crucial role of matrix m1 protein in assembly and budding of influenza particles, in all vlps structures, m1 protein have been considered as a main component. ...

The QCD sector of the system SANC is presented. QCD theoretical predictions for several processes of high energy interactions of fundamental particles at the one-loop precision level for up to some 3and 4-particle processes are implemented.

We propose a computable Galois-connection between, on the one hand, Cattell’s 16-Personality-Factor (16PF) Profiles, one of the most comprehensive and widely-used personality measures for non-psychiatric populations and their containing PsychEval Personality Profiles (PPPs) for psychiatric populations, and, on the other hand, Szondi’s personality profiles (SPPs), a less well-known but, as we sh...

Why some strains of a species exhibit a certain phenotype (e.g. drug resistant) but not the other strains of the same species is a critical question to answer. Studying the metabolism of the two groups of strains may discover the corresponding pathways that are conserved in the first group but not in the second group. However, only a few tools provide functions to compare two groups of metaboli...

These proceedings summarize lectures that were delivered as part of the 2002 and 2003 Theoretical Advanced Study Institutes in elementary particle physics (TASI) at the University of Colorado at Boulder. They are intended to provide a pedagogical introduction to cosmology aimed at advanced graduate students in particle physics and string theory.
