Mass spectrometry for fundamental studies in metrology and atomic, nuclear and particle physics requires extreme sensitivity and efficiency as well as ultimate resolving power and accuracy. An overview will be given on the global status of high-accuracy mass spectrometry for fundamental physics and metrology. Three quite different examples of modern mass spectrometric experiments in physics are...

The concept of Generalized Snapshot Isolation (GSI) has been recently proposed as a suitable extension of conventional Snapshot Isolation (SI) for replicated databases. In GSI, transactions may use older snapshots instead of the latest snapshot required in SI, being able to provide better performance without significantly increasing the abortion rate when write/write conflicts among transaction...

In this paper we propose two iterative methods, a Jacobi-type iteration (JI) and a Gauss-Seidel-type iteration (GSI), for the computation of energy states of the time-independent vector Gross-Pitaevskii equation (VGPE) which describes a multicomponent Bose-Einstein condensate (BEC). A discretization of the VGPE leads to a nonlinear algebraic eigenvalue problem (NAEP). We prove that the GSI meth...

In June 2009 the Helmholtz-Institute Mainz (HIM) was founded. The research activities of HIM are supported by the integrated department of accelerator physics and integrated detectors (ACID) [1]. Within the scope of ACID a collaboration of the Institute of Applied Physics of University Frankfurt (IAP) and the GSI acceleration division is established. Its longterm task should be the design and t...

The session on beam losses, halo generation and collimation is the first of two sessions of the BEAM07 Workshop, which were devoted to specific CERN-GSI subjects and were meant to be the follow up of last year’s CERNGSI Bilateral Meeting on Collective Effects, which took place on March 30-31, 2006 at the GSI-Darmstadt.

The Prevotella ruminicola 23 genome encodes three different glutamine synthetase (GS) enzymes: glutamine synthetase I (GSI) (ORF02151), GSIII-1 (ORF01459), and GSIII-2 (ORF02034). GSI, GSIII-1, and GSIII-2 have each been heterologously expressed in and purified from Escherichia coli. The subunit molecular mass of GSI was 56 kDa, while GSIII-1 and GSIII-2 were both 83 kDa. Optimal conditions for...

Objective. To explore whether the image noises and the metal artifacts could be further managed by the combined use of two technologies, the adaptive statistical iterative reconstruction (ASIR) and the monochromatic imaging generated by gemstone spectral imaging (GSI) dual-energy CT. Materials and Methods. Fifty-one patients with 318 spinal pedicle screws were prospectively scanned with dual en...

Studies on seasonally breeding wild birds of Indian sub-continent have been grossly neglected in terms of cyclic changes in total serum Ca, Pi and GSI with respect to natural photoperiod. Bank myna is one of the commonest wild seasonal breeder of Northern Indian plains. The bird breeds during April to July. With the advent of summer (in March) and increasing natural photoperiod a marked rise in...
