Modification of the amorphous carbon films by the ns-laser irradiationCentral European Journal of Physics - Tập 9 - Trang 1344-1350 - 2011
Alfonsas Grigonis, Liutauras Marcinauskas, Vinga Vinciunaite, Gediminas Raciukaitis
The effect of a nanosecond laser irradiation of thin (60 and 145 nm) amorphous, diamond-like carbon films deposited on Si substrate by an ion beam deposition (IBD) from pure acetylene and acetylene/hydrogen (1:2) gas mixture was analyzed in this work. The films were irradiated with the infrared (IR) and ultraviolet (UV) radiation of the nanosecond Nd:YAG lasers working at the first (1.16 eV) and t...... hiện toàn bộ
Extreme gravitational lensing in vicinity of Schwarzschild-de Sitter black holesCentral European Journal of Physics - Tập 5 - Trang 599-610 - 2007
Pavel Bakala, Petr Čermák, Stanislav Hledík, Zdeněk Stuchlík, Kamila Truparová
We have developed a realistic, fully general relativistic computer code to simulate optical projection in a strong, spherically symmetric gravitational field. The standard theoretical analysis of optical projection for an observer in the vicinity of a Schwarzschild black hole is extended to black hole spacetimes with a repulsive cosmological constant, i.e, Schwarzschild-de Sitterspacetimes.

Critical properties of a random transverse crystal field Ising model with bond dilutionCentral European Journal of Physics - Tập 9 - Trang 1084-1089 - 2011
Ling Wen, Yan Shi-Lei
Within effective field theory (EFT), the critical properties of a random transverse crystal field Ising model with bond dilution are studied on a square lattice. Under both weak and strong bond dilution conditions, we consider three cases (α = 0,±0.5) of a transverse crystal field ratio, obtaining global phase diagrams in T−D
x space for changes in the random transverse cry...... hiện toàn bộ
Classical color fields as a dark matter candidateCentral European Journal of Physics - Tập 5 - Trang 342-350 - 2007
Vladimir Dzhunushaliev
A model of Dark Matter is proposed where the Dark Matter is a classical color field. The color fields are invisible as they may interact with colored elementary particles like the ’t Hooft-Polyakov monopole only. Comparison with the Universal Rotation Curve is carried out.
Non-coding RNAs and complex distributed genetic networksCentral European Journal of Physics - Tập 9 - Trang 909-918 - 2010
Vladimir P. Zhdanov
In eukaryotic cells, the mRNA-protein interplay can be dramatically influenced by non-coding RNAs (ncRNAs). Although this new paradigm is now widely accepted, an understanding of the effect of ncRNAs on complex genetic networks is lacking. To clarify what may happen in this case, we propose a mean-field kinetic model describing the influence of ncRNA on a complex genetic network with a distributed...... hiện toàn bộ
Instability transitions and ensemble equivalence in diffusive flowCentral European Journal of Physics - Tập 7 - Trang 575-583 - 2009
Meesoon Ha
We investigate the critical behavior of one-dimensional (1D) stochastic flow with competing nonlocal and local hopping events, in context of the totally asymmetric simple exclusion process (TASEP) with a defect site in a 1D closed chain. The defect site can effectively generate various boundary conditions, controlling the total number of particles in the system. Both open and periodic-like setups ...... hiện toàn bộ
Time-dependent density functional theory molecular dynamics simulation of doubly charged uracil in gas phaseCentral European Journal of Physics - Tập 12 - Trang 97-102 - 2014
Pablo López-Tarifa, Marie-Anne Hervé du Penhoat, Rodophe Vuilleumier, Marie-Pierre Gaigeot, Ursula Rothlisberger, Ivano Tavernelli, Arnaud Le Padellec, Jean-Philippe Champeaux, Manuel Alcamí, Patrick Moretto-Capelle, Fernando Martín, Marie-Françoise Politis
We use time-dependent density functional theory and Born-Oppenheimer molecular dynamics methods to investigate the fragmentation of doubly ionized uracil in gas phase. Different initial electronic excited states of the dication are obtained by removing electrons from different inner-shell orbitals of the neutral species. We show that shape-equivalent orbitals lead to very different fragmentation p...... hiện toàn bộ
Complementarity and post-selection in an atomic double-slit interferometerCentral European Journal of Physics - Tập 11 - Trang 923-927 - 2013
Bertúlio de Lima Bernardo
This paper analyzes, theoretically, an atomic double-slit interferometer in order to probe the extent to which complementary properties affect quantum interference. It is shown that if the energy eigenstates of a two-level atom are one-to-one correlated with its particle and wave behaviors, complementary phenomena can be measured simultaneously, indicating a reinterpretation of the complementarity...... hiện toàn bộ
