A theoretical analysis has been made of the van der Waals vibration-rotation-electron spin states of the 0 2-0 2 dimer in its 32 g "-32 g-electronic ground state. This analysis is based on a Hamiltonian that includes a spin-dependent 0 2-0 2 interaction potential and it involves also the permutation-inversion symmetry of the system. We have constructed some hindered internal rotor models for th...

The structures of the compact and swollen southern bean mosaic virus (SBMV) particles have been compared by X-ray diffraction and proton magnetic resonance (PMR). Small-angle X-ray scattering showed that removal of divalent cations at alkaline pH causes the particle diameter to increase from 289Å in the native SBMV by 12% in solution and by 9% in microcrystals. The swelling is fully reversible ...

This paper proposes a retrial queueing model with the finite number of sources to evaluate the performance of spectrum renting in mobile cellular networks. The model incorporates necessary ingredients such as the finite number of subscribers, their impatience and a queue for the outbound service. To consider the specific feature of spectrum renting and the current mobile cellular technology, a ...

Dynamic binary analysis has demonstrated its strength in solving a wide-spectrum of computer security problems, such as malware analysis, protocol reverse engineering, vulnerability detection, diagnosis, and defense, software testing, etc. An extensible platform for dynamic binary analysis provides a foundation for solving these problems. To enable a variety of applications, we explore a unique...

Despite the comorbidity between motor difficulties and certain disabilities, limited research has examined links between early motor, cognitive, and social skills in preschool-aged children with developmental disabilities. The present study examined the relative contributions of gross motor and fine motor skills to the prediction of improvements in children's cognitive and social skills among 2...

We construct a non-decreasing pure jump Markov process, whose jump measure heavily depends on the values taken by the process. We determine the singularity spectrum of this process, which turns out to be random and to depend locally on the values taken by the process. The result relies on fine properties of the distribution of Poisson point processes and on ubiquity theorems.

Formulas for computing the number of Df2-algebra structures that can be defined over Bn, where Bn is the Boolean algebra with n atoms, as well as the fine spectrum of Df2 are obtained. Properties of the lattice of all subvarieties of Df2, (Df 2), are exhibited. In particular, the poset Sifin(Df2) is described.

A single-scan method is proposed to shorten the acquisition time for an NMR 2D J-resolved spectrum to 1 second. With high SNRs and acceptable resolutions, it constitutes an effective tool for obtaining decoupled proton spectra and fine scalar-coupling splitting patterns.

We propose a new minimal supersymmetric scenario with virtually no fine-tuning in the electroweak symmetry breaking. It favors light supersymmetric spectrum below a few TeV and predicts definite relations among stop and gaugino masses and LSP higgsino with μ . 200 GeV, which are within the reach of coming LHC experiment 1.

The spectroscopy of molecules doped into superfluid helium droplets provides information on both, the dopant molecule and the helium environment. Electronic spectra of 9,10-dichloroanthracene in helium droplets are presented and compared with corresponding gas phase spectra to unravel the influence of the helium environment. The combined investigation of fluorescence excitation and dispersed em...
