The longitudinal resistivity of two-dimensional 2D electrons placed in strong magnetic field is significantly reduced by applied electric field, an effect which is studied in a broad range of magnetic fields B and temperatures T in GaAs quantum wells with high electron density. The data are found to be in good agreement with theory, considering the strong nonlinearity of the resistivity as the ...

The molecular algebraic model based on three and four alpha clusters is used to describe the inelastic scattering of particles populating low-lying states in $^{12}$C $^{16}$O. Optical potentials formfactors are obtained by folding densities transition within model. One-step multi-step processes can be included reaction mechanism calculation. In spite simplicity approach with rotations vibratio...

This paper describes a continuum model for analyzing the inelastic behavior of a single walled carbon nanotube (SWCNT) in different loading conditions. Because of limitations in using molecular dynamics (and other atomic methods) to model the failure load of the SWCNT, continuum mechanics methods are considered in this paper. Based on some experimental and theoretical results, an elasto-plastic...

recently, two of the authors have introduced the collapse capacity spectrummethodology, which allows the assessment of the collapse capacity of highly inelastic p-deltasensitive regular frame structures without performing non-linear time-history analyses. the mainingredient of this method is the collapse capacity spectrum, which represents the seismic collapsecapacity of an inelastic non-deteri...

Surface-bound molecular rotation can occur with the rotational axis either perpendicular (azimuthal) or parallel (altitudinal) to the surface. The majority of molecular rotor studies involve azimuthal rotors, whereas very few altitudinal rotors have been reported. In this work, altitudinal rotors are formed by means of coupling aryl halides through a surface-mediated Ullmann coupling reaction, ...

Nonexponential attenuation of hadrons in nuclei and renormalization of data for hard QCD probes. For classical particles the propagation through a medium is exponentially attenuated with the path length L, i.e. the survival probability in a nucleus decreases as exp(−σhN in ρL), where σ in is the cross section of inelastic hadron-nucleon collisions, and ρ is the nuclear density. This kind of att...

A chemical reaction model, suitable for use in the Direct Simulation Monte Carlo (DSMC) method, is developed to simulate hypervelocity collisions of an important reaction in atmospheric-jet interactions O(3P)+HCl(1Σ ) OH(2Π)+Cl(2P). The model utilizes the Quasi-Classical Trajectory (QCT) method with two potential energy surfaces (PES), new benchmark triple A and A surfaces and London-Eyring-Pol...

Researches show that the strength criterion is inadequate for design of structures against seismic loads. Since structures yield and experience plastic deformation under strong ground motion, considering structural damage with inelastic behavior may be a considerable criterion for design and control of the structures.In this paper, three steel structures with dual system consisting of intermedi...
