Dispersion Relations and Polarizations of Low-frequency Waves in Two-fluid Plasmas / Zhao, Jinsong
Analytical expressions for the dispersion relations and polarizations of low-frequency waves in magnetized plasmas based on two-fluid model are obtained. The properties of waves propagating at different angles (to the ambient magnetic field $\mathbf{B}_{0}$) and \beta (the ratio of the plasma to magnetic pressures) values are investigated. [...]

Resonant diffusion of normal alkanes in zeolites: Effect of the zeolite structure and alkane molecule vibrations / Tsekov, R ; Smirniotis, P G
Diffusion of normal alkanes in one-dimensional zeolites is theoretically studied on the basis of the stochastic equation formalism. The calculated diffusion coefficient accounts for the vibrations of the diffusing molecule and zeolite framework, molecule-zeolite interaction, and specific structure of the zeolite. [...]

High-throughput Imaging of Self-luminous Objects through a Single Optical Fiber / Barankov, Roman ; Mertz, Jerome
Imaging through a single optical fiber offers attractive possibilities in many applications such as microendoscopy or remote sensing. However, the direct transmission of an image through an optical fiber is difficult because spatial information is scrambled upon propagation. [...]

Imaging instantaneous electron flow with ultrafast resonant x-ray scattering / Popova-Gorelova, Daria ; Santra, Robin
We propose a novel way to image dynamical properties of nonstationary electron systems using ultrafast resonant x-ray scattering. Employing a rigorous theoretical analysis within the framework of quantum electrodynamics, we demonstrate that a single scattering pattern from a nonstationary electron system encodes the instantaneous interatomic electron current in addition to the structural information usually obtained by resonant x-ray scattering from stationary systems.

Sensitivity of $\beta$-decay rates to the radial dependence of the nucleon effective mass / Severyukhin, A P (IPNL) ; Margueron, Jérôme (IPNL) ; Borzov, I N (IPNO) ; Van Giai, Nguyen (IPNO)
We analyze the sensitivity of $\beta$-decay rates in 78 Ni and 100,132 Sn to a correction term in Skyrme energy-density functionals (EDF) which modifies the radial shape of the nucleon effective mass. This correction is added on top of several Skyrme parametrizations which are selected from their effective mass properties and predictions about the stability properties of 132 Sn. [...]

H2O vapor excitation in dusty AGB envelopes. A PACS view of OH 127.8+0.0 / Lombaert, R ; Decin, L ; de Koter, A ; Blommaert, J A D L ; Royer, P ; De Beck, E ; de Vries, B L ; Khouri, T ; Min, M
Context: AGB stars lose a large percentage of their mass in a dust-driven wind. This creates a circumstellar envelope, which can be studied through thermal dust emission and molecular emission lines. [...]

Gravitational Encounters and the Evolution of Galactic Nuclei. I. Method / Merritt, David
An algorithm is described for evolving the phase-space density of stars or compact objects around a massive black hole at the center of a galaxy. The technique is based on numerical integration of the Fokker-Planck equation in energy-angular momentum space, f(E,L,t), and includes, for the first time, diffusion coefficients that describe the effects of both random and correlated encounters (resonant relaxation), as well as energy loss due to emission of gravitational waves.

New challenges in unified theories / Zoupanos, G (CERN)
Among the research directions that we have presented during the Workshop SQS2011, we have chosen to discuss here in some detail the derivation of the effective action in four dimensions of the tendimensional N = 1 heterotic supergravity coupled to N = 1 supersymmetric Yang-Mills resulting from the dimensional reduction over nearly-Kaehler manifolds..

Cosmology / García-Bellido, J (Madrid, IFT)
In these lectures I review the present status of the so-called Standard Cosmological Model, based on the hot Big Bang Theory and the Inflationary Paradigm. I will make special emphasis on the recent developments in observational cosmology, mainly the acceleration of the universe, the precise measurements of the microwave background anisotropies, and the formation of structure like galaxies and clusters of galaxies from tiny primordial fluctuations generated during inflation..

Ultra-High-Energy Cosmic Rays / Dova, M T (La Plata, Inst. Natl. Phys. ; La Plata U. ; Buenos Aires, CONICET)
The origin of the ultra high energy cosmic rays (UHECR) with energies above E > 10 17 eV, is still unknown. The discovery of their sources will reveal the engines of the most energetic astrophysical accelerators in the universe. [...]
