Optical quality single crystals of glycine thiourea (GT), a new organic nonlinear optical (NLO) crystal, were grown from aqueous solution by slow evaporation method. Solubility of GT was determined at various temperatures. Single crystal X-ray diffraction studies indicate that GT crystallizes in the monoclinic crystal system. Various diffracting planes of the grown crystal were identified from ...

We demonstrate for the first time the applicability of multimodal nonlinear optical (NLO) microscopy to the interrogation of stented coronary arteries under different diet and stent deployment conditions. Bare metal stents and Taxus drug-eluting stents (DES) were placed in coronary arteries of Ossabaw pigs of control and atherogenic diet groups. Multimodal NLO imaging was performed to inspect c...

In this work we determine the linear and non-linear optical properties of a Fluoro-N-Acylhydrazide derivative (FBHZ), using a combined supermolecule approach and an iterative scheme of electrostatic polarization, where the atoms of neighbouring molecules are represented by point charges. Our results for non-linear optics (NLO) are comparable to those found experimentally, suggesting that FBHZ c...

The production of dijet events at HERA is dominated by processes in which a virtual photon, coupling to the electron, interacts with a parton in the proton. In the region of photon virtuality Q ≫ ΛQCD, hard collisions of the photons do not necessitate the introduction of the concept of the resolved photon (as for the real photon) and the process can in principle be described by the direct photo...

The measurement of triple differential dijet cross sections in e±p interactions in the H1 experiment in the region of photon virtualities 2 < Q < 80GeV, inelasticities 0.1 < y < 0.85, jet transverse energies E∗ T 1 > 7GeV, E ∗ T 2 > 5GeV, and pseudorapidities −2.5 < η∗ 1 , η∗ 2 < 0 is presented. The analysis was done in the γ∗p centre-of-mass frame using an integrated luminosity of 57.6 pb−1. T...

Abstract. Several results from the ZEUS Collaboration were presented at this Workshop. The highlights are presented in this summary, and include results from NLO QCD fits and determination of αS, from forward jets and diffractive final states, from pentaquarks and searches and from heavy flavour production. Also the first results from the analysis of the HERA II e+p/e−p data are shown.

Ga-based III-V materials, such as, GaAs, GaN and AlGaN, have a wide-range of applications in the fields of high-speed, high-temperature, high-power and high-frequency electronic and optoelectronic devices, due to their unique physical properties. This thesis is devoted to the time-resolved characterization of ultrafast, nonequilibrium carrier and phonon dynamics in Ga-based III-V materials and ...

We discuss the determination of polarized parton distributions from a NLO analysis of recent experimental data. We extract the first moment of the polarized quark and gluon distribution and assess the corresponding uncertainties, with special regard to those related to scheme dependence. Talk given at DIS96, Rome, April 1996 to be published in the proceedings

We extract the ratio of the down (d) and up (u) parton distribution functions (PDF’s) from the ratio of NMC deuteron and proton structure function F d 2 /F p 2 , using corrections for nuclear binding effects in the deuteron, which are extracted from the nuclear dependence of SLAC F2 data. Significant corrections to the d quark distribution in standard PDF’s are required, especially at high x. T...
