Abstract:
Lie group point transformations applied to the one-dimensional Vlasov– Maxwell equations yield general similarity forms for the dependent and independent variables. One class of such solutions is seemingly like Bern-stein-Greene-Kruskal solutions in allowing a relatively free choice of electric field, but with a more complex time dependence. The phase trajectories of the particles are found here for both temporally damped and (possibly unphysical) growing electric fields in this class by numerical integration in the original and in transformed co-ordinates.

In this study, we examine the Berry’s phase equation for E-M curves in the C − direction and W − direction throughout an optic fiber via alternative moving frame in three dimensional space. Moreover, electromagnetic curve’s C − direction and W − direction Rytov parallel transportation laws are defined. Finally, we examine the electromagnetic curve with anholonomic co-ordinates for Maxwellian evolution by Maxwell’s equation.

We report exact quantum dynamics calculations of the eigenstate energy levels for the bound rovibrational states of the Ar2Ne complex, across the range of J values for which such states are observed (J = 0–35). All calculations have been carried out using the ScalIT suite of parallel codes. These codes employ a combination of highly efficient methods, including phase-space optimized discrete variable representation, optimal separable basis, and preconditioned inexact spectral transform (PIST) methods, together with an effective massive parallelization scheme.

Abstract:
Imaging of organic crystals in the electron microscope is limited by their sensitivity to the electron beam, with even the most stable molecules only giving a resolution of ~3Å. By contrast, electron diffraction requires a lower beam intensity, and so can give much better resolution, down to ~lÅ under favourable conditions. Intensities may be measured directly from the diffraction pattern, and the phase determination problem can be surmounted by applying the maximum entropy method, which chooses phases by likelihood estimation.It was decided to apply this method to the organic molecule anthant

Abstract: The Dielectric losses are theoretical investigated for CaxSr1-xTiO3 and PbxSr1-xTiO3 single crystal perovskites in paraelectric phase as a function of composition and temperature. In our calculation, the Silverman Joseph`s Hamiltonian augmented with fourth order phonon co-ordinates using double time temperature dependent Green`s Function technique is used. Dielectric loss is estimated for various value of x. The substitutional impurity depend dielectric losses increases with increases in composition x at room temperature and Dielectric loss tangent (tan δ) increases with increasing t

Abstract:
Genes under control of super-enhancers are expressed at extremely high levels and are frequently associated with nuclear speckles. Recent data suggest that the high concentration of unphosphorylated RNA polymerase II (Pol II) and Mediator recruited to super-enhancers create phase-separated condensates. Transcription initiates within or at the surface of these phase-separated droplets and the phosphorylation of Pol II, associated with transcription initiation and elongation, dissociates Pol II from these domains leading to engagement with nuclear speckles, which are enriched with RNA processing

Abstract:
Reliable and accurate kinematic localization is becoming more important in autonomous vehicles and advanced driver assistance systems (ADAS) which need to precisely locate vehicles on roadways. Code-base undifferenced GNSS receivers provide rough position estimates with errors too large to be practical for such applications. Carrier-phase observations are able to provide sub-meter accuracies and have been receiving much attention in recent years. Iterative methods are commonly used for solving the double-difference equations and find the receiver co-ordinates. This paper presents a non-iterati

Abstract:
A finite volume method for the computation of rotor/stator interaction for stages with arbitrary rotor/stator pitch ratios is presented and partly validated in this paper. The method which solves the unsteady three-dimensional Euler equations is formulated in the four-dimensional time-space domain. The method of time inclination is utilized to account for unequal pitchwise periodicity by distributing time co-ordinates at the grid nodes such that phase lagged boundary conditions can be employed. Calculated results show excellent agreement with the results of a reference solver for the validatio

Abstract:
The fundamental understanding of the dynamic interactions between multiphase flow in the reservoir and that in the wellbore remains surprisingly weak. The classical way of dealing with these interactions is via inflow performance relationships (IPR’s), where the inflow from the reservoir is related to the pressure at the bottom of the well, which is a function of the multiphase flow behaviour in the well. Steady-state IPR’s are normally adopted, but their use may be erroneous when transient multiphase flow conditions occur. Transient multiphase flow in the wellbore causes problems in well test
