General stability result in a memory-type porous thermoelasticity system of type III
Abstract In this paper, we consider a one-dimensional porous thermoelasticity system of type III with a viscoelastic damping acting on one of the equations. We establish a general decay result for the case of equal as well as different speeds of...

Determination of neutrino mass hierarchy by 21 cm line and CMB B-mode polarization observations
Abstract We focus on the ongoing and future observations for both the 21 cm line and the CMB B-mode polarization produced by a CMB lensing, and study their sensitivities to the effective number of neutrino species, the total neutrino mass, and the...

Spontaneous spacetime reduction and unitary weak boson scattering at the LHC
Abstract Theories of quantum gravity predict spacetime dimensions to become reduced at high energies, a striking phenomenon known as spontaneous dimensional reduction (SDR). It has found nice applications to astrophysics and collider...

Reprint of: Femtosecond transition-state spectroscopy of iodine: From strongly bound to repulsive surface dynamics
Abstract The application of femtosecond transition-state spectroscopy (FTS) to molecular iodine is reported. The real-time motion of wave packets prepared coherently in the bound B state is observed. In addition, the motion is probed near and above...

A 130 GeV gamma ray signal from supersymmetry
Abstract The viability of neutralino dark matter as an explanation of the 130 GeV gamma ray signal from the Galactic Center recently observed by the Fermi Large Area Telescope is examined. It is found that the signal can be compatible with a sharp...

Precision Magnetic Field Mapping for the 3He Neutron Spin Filter
Abstract 3He neutron spin filters require a homogeneous magnetic field, otherwise the nuclear polarization of the 3He gas will easily be lost by small magnetic field gradients. Magnetic cavities with field gradients of 10−4/cm...

Emergent D5-brane background from D-strings
Abstract We solve the worldsheet theory describing the near-horizon dynamics of a D-string in the presence of a very large number N of D5-branes. The model is pre-geometric in the sense that the near-horizon worldsheet Lagrangian does not have...

Study of As50Se50 Thin Film Dissolution Kinetics in Amine based Solutions
Abstract Chalcogenide glass thin films are suitable materials for micro optical elements fabrication due to their convenient physical and chemical properties. They are generally photosensitive and thus can be selectively etched. Therefore they can...

Numerical modeling of thermoelastic generation of ultrasound by laser irradiation in the coupled thermoelasticity
Abstract Laser-generation of ultrasound is investigated in the coupled dynamical thermoelasticity in the presented paper. The coupled heat conduction and wave equations are solved using finite differences. It is shown that the application of...

On the complementarity of Higgs and radion searches at LHC
Abstract Models with 3-branes in extra dimensions typically imply the existence of a radion, φ, that can mix with the Higgs, h, thereby modifying the Higgs properties and the prospects for its detectability at the LHC. The presence of the φ will...

Hybrid Dirac fields
Abstract Hybrid Dirac fields are fields that are general superpositions of the annihilation and creation parts of four Dirac spin 1/2 fields, ψ (±)(x;±m), whose annihilation and creation parts obey the Dirac equation with mass m ...

Scalar and vector form factors of the in-medium nucleon
Abstract Using the quark–meson coupling model, we calculate the form factors at σ- and ω-nucleon strong-interaction vertices in nuclear matter. The Peierls–Yoccoz projection technique is used to take account of center of mass and recoil corrections. ...

The Fourier Monte Carlo Approach to Lattice Spin Models
Abstract Recently we have developed a Monte Carlo algorithm for lattice spin systems that relies exclusively on the use of Fourier amplitudes without making any reference to the underlying real-space configurations. This article is devoted to give a ...

Improvement of China Energy Label System to Promote Sustainable Energy Consumption
Abstract Energy label system is a good way to promote sustainable energy consumption. As consumers are the users of energy label, it can stimulate production, which promotes forming of sustainable consumption patterns. In China, energy label system...
