Applications of discretized light-cone quantization (DLCQ) to (3+1)-dimensional Yukawa theory with Pauli– Villars regulators and of supersymmetric DLCQ (SDLCQ) to (2+1)-dimensional super Yang–Mills theory are discussed. The ability of these methods to provide wave functions as well as spectra is emphasized.

In present work, the SHIELD code system have been used to investigate the physics properties of spallation neutron target, such as the neutron spectra, the yield, the radioactivity in the target and the target size etc. The fragment mass distribution of the residual nuclei from proton-induced spallation reaction on thick lead target with energy 1.6 GeV have been analysed also. Radiation damage,...

The propagation of magneto-thermoelastic disturbances in an elastic half-space caused by the application of a thermal shock on the stress-free bounding surface in contact with vacuum is investigated. The theory of thermoelasticity III proposed by Green and Naghdi is used to study the interaction between elastic, thermal, and magnetic fields. Small-time approximations of solutions for displaceme...

Harmonic Motion Imaging for Focused Ultrasound (HMIFU) is a technique that can perform and monitor high-intensity focused ultrasound (HIFU) ablation. An oscillatory motion is generated at the focus of a 93-element and 4.5 MHz center frequency HIFU transducer by applying a 25 Hz amplitude-modulated signal using a function generator. A 64-element and 2.5 MHz imaging transducer with 68kPa peak pre...

The design and optimization of nanostructure-based surface acoustic wave (SAW) gas sensor is analyzed based on TiO2 sensing layer and modified electrode dimensions. The sensitivity of the gas sensor depends upon the type of sensing layer used and active surface area obtained by varying the aspect ratio. The performance of the sensor is observed from 0.1ppm to 100ppm concentration of ...

Equatorial planetary scale wave modes such as Kelvin waves or Rossby-gravity waves are excited by convective processes in the troposphere. In this paper an analysis for these and other equatorial wave modes is carried out with special focus on the stratosphere using temperature data from the SABER satellite instrument as well as ECMWF temperatures. Space-time spectra of symmetric and antisymmet...

in this paper, the effect of bedrock inclination on seismic performance of slopes is investigated. the study was conducted based on dynamic analysis of different slopes, evaluation of the earthquake acceleration in sliding mass, and calculating the permanent displacement of the slope, using newmark sliding block. the investigation indicates that variation of the bedrock inclination may cause th...

The application of femtosecond pump-probe photoelectron spectroscopy to directly observe vibrational wave packets passing through an avoided crossing is investigated using quantum wave packet dynamics calculations. Transfer of the vibrational wave packet between diabatic electronic surfaces, bifurcation of the wave packet, and wave packet construction via nonadiabatic mixing are shown to be obs...
