Theoretical Modeling of J/psi Yield Modifications in Proton (Deuteron) - Nucleus Collisions at High Energy
Theoretical Modeling J/psi Yield Modifications Proton (Deuteron) Nucleus Collisions High Energy
2010/12/29
Understanding the detailed production and hadronization mechanisms for heavy quarkonia and their modification in a nuclear environment presents one of the major challenges in QCD. Calculations includi...
A theoretical perspective on the glass transition and nonequilibrium phenomena in disordered materials
theoretical perspective glass transition nonequilibrium phenomena disordered materials
2010/11/22
We provide a theoretical perspective on the glass transition in molecular liquids at thermal equi-librium, on the spatially heterogeneous and aging dynamics of disordered materials, and on the rheolog...
A Simplified, Bohr Quantum Theoretical Derivation of the Unruh Temperature, Entropy, and Evaporation
General Relativity and Quantum Cosmology(gr-qc) Quantum Physics(quant-ph)
2010/11/9
In this work we reproduce Unruh temperature for a spherical physical system using a simplified rule, very similar to Bohr angular momentum quantization postulate interpreted via de Broglie relation, a...
A brief review on the theoretical status of hadronic charm decays is presented. We emphasize the analyses based on the diagrammatic approach and the connection of weak annihilation with final-state re...
Theoretical Study of the Soft Optic Mode Scattering in a Relaxor Ferroelectric: the Strong Effect of the Depolarizing Fields
Theoretical Study of the Soft Optic Mode Scattering Relaxor Ferroelectric Depolarizing Fields
2010/11/19
We analyze scattering of the transverse optic modes by spherically symmetric Polarized Nano Regions (PNR) in the paraelectric phase of relaxor ferroelectrics. Calculations have done in the frame of me...

Variability of black-hole accretion discs: a theoretical study
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2010/12/29
This thesis investigates phenomena occurring in black-hole accretion discs which are likely to induce high-frequency quasi-periodic variability. Two classes of pseudo-relativistic theoretical models a...
The State of Self-Organized Criticality of the Sun During the Last Three Solar Cycles. II. Theoretical Model
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The observed powerlaw distributions of solar flare parameters can be interpreted in terms of a nonlinear dissipative system in the state of self-organized criticality (SOC).
Theoretical Support for the Hydrodynamic Mechanism of Pulsar Kicks
High Energy Astrophysical Phenomena (astro-ph.HE) Solar and Stellar Astrophysics (astro-ph.SR) High Energy Physics - Phenomenology (hep-ph)
2010/12/24
The collapse of a massive star's core, followed by a neutrino-driven, asymmetric supernova explosion, can naturally lead to pulsar recoils and neutron star kicks.
The immune system recognizes a myriad of invading pathogens and their toxic products. It does so with a finite repertoire of antibodies and T cell receptors. We here describe theories that quantify th...
Folding of set-theoretical solutions of the Yang-Baxter equation
set-theoretical solution of the quantum Yang-Baxter equation parabolic subgroups of Garside groups folding
2010/12/8
We establish a correspondence between the invariant subsets of a non-degenerate symmetric set-theoretical solution of the quantum Yang-Baxter equation and the parabolic subgroups of its structure grou...
Theoretical implication of reversals of the ozone weekend effect systematically observed in Japan
the ozone weekend effect Japan
2010/8/16
Systematic changes of the ozone weekend effect are found over broad areas of Japan. These changes are characterized by (1) spatial reversals from a weekend increase in the vicinity of huge precursor s...
A theoretical study of the effects of polar substitution on the activation barriers for internal rotation around the C-N bond in p-substituted nitrosobenzenes: comparison of DFT and MP2 calculations
Para-substituted nitrosobenzenes C-N bond rotation polar substituent effect
2010/10/18
The activation barriers for internal rotation around the C-N bond in p-substituted nitrosobenzenes were calculated using the density functional theory (DFT) and second-order Møller-Plesset (MP2...
