Automorphisms of the semigroup of endomorphisms of free associative algebras
A. Kanel-Belov, A. Berzins, R. Lipyanski
Let be a free associative algebra in freely generated over by a set , be the semigroup of endomorphisms of $…
Electric field induced hyperfine level-crossings in (nD)Cs at two-step laser excitation: experiment and theory
M. Auzinsh, K. Blushs, R. Ferber +3
The pure electric field level-crossing of m_F Zeeman sublevels of hyperfine F levels at two-step laser excitation was described theoretically and studied experimentally for the nD_…
Experimental investigation of the breakdown of the Onsager-Casimir relations
C. A. Marlow, R. P. Taylor, M. Fairbanks +2
We use magnetoconductance fluctuation measurements of phase-coherent semiconductor billiards to quantify the contributions to the nonlinear electric conductance that are asymmetric…
Semantics of UML 2.0 Activity Diagram for Business Modeling by Means of Virtual Machine
Valdis Vitolins, Audris Kalnins
The paper proposes a more formalized definition of UML 2.0 Activity Diagram semantics. A subset of activity diagram constructs relevant for business process modeling is considered.…
An abundance analysis of the symbiotic star CH Cyg
M. R. Schmidt, L. Zacs, J. Mikolajewska +1
The photospheric abundances for the cool component of the symbiotic star CH Cyg were calculated for the first time using high-resolution near-infrared spectra and the method of of…
Symplectic integration approach for metastable systems
E. Klotins
Nonadiabatic behavior of metastable systems modeled by anharmonic Hamiltonians is reproduced by the Fokker-Planck and imaginary time Schrodinger equation scheme with subsequent sym…
Accelerator Testing of the General Antiparticle Spectrometer, a Novel Approach to Indirect Dark Matter Detection
C J Hailey, T Aramaki, W W Craig +7
We report on recent accelerator testing of a prototype general antiparticle spectrometer (GAPS). GAPS is a novel approach for indirect dark matter searches that exploits the antide…
On metal-deficient barium stars and their link with yellow symbiotic stars
A. Jorissen, L. Zacs, S. Udry +2
This paper addresses the question of why metal-deficient barium stars are not yellow symbiotic stars (YSyS). Samples of (suspected) metal-deficient barium (mdBa) stars and YSyS hav…
Zero range model of traffic flow
J. Kaupuzs, R. Mahnke, R. J. Harris
A multi--cluster model of traffic flow is studied, in which the motion of cars is described by a stochastic master equation. Assuming that the escape rate from a cluster depends on…
The phase diagram of the multi-dimensional Anderson localization via analytic determination of Lyapunov exponents
V. N. Kuzovkov, W. von Niessen
The method proposed by the present authors to deal analytically with the problem of Anderson localization via disorder [J.Phys.: Condens. Matter {\bf 14} (2002) 13777] is generaliz…
Collisional and thermal ionization of sodium Rydberg atoms I. Experiment for nS and nD atoms with n=8-20
I. I. Ryabtsev, D. B. Tretyakov, I. I. Beterov +3
Collisional and thermal ionization of sodium nS and nD Rydberg atoms with n=8-20 has been studied. The experiments were performed using a two-step pulsed laser excitation in an eff…
Fokker-Planck equation for coupled anharmonic oscillators: symplectic integration and application to mean-field model of cooperative behavior
E. Klotins
Kinetics of systems specified by anharmonic, nonconservative and nonlocally coupled model Hamiltonians is reproduced in the Fokker-Planck and imaginary time Schrodinger equation te…
Surface tension and interfacial fluctuations in d-dimensional Ising model
J. Kaupuzs
The surface tension of rough interfaces between coexisting phases in 2D and 3D Ising models are discussed in view of the known results and some original calculations presented in t…
