Factorisation in diffraction [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2010
Recent experimental data on dijet cross sections in diffractive photoproduction at HERA collider were analysed with emphasis on QCD factorisation breaking effects. Dijet photoproduction data of jets with low transverse energy E T1 > 5 GeV indicated a possible dependence on E T of the suppression of jet production with respect to ...

A Model-Based RF Hand Motion Detection System for Shadowing Scenarios

open access: yesIEEE Access, 2020
With the explosive growth of mobile computing, new modes of human-computer interaction (HCI) are emerging and becoming feasible. Compared to vision-based systems that require lighting, radio frequency (RF)-based hand motion detection systems are becoming

Fourier transform infrared spectrophotometry and X-ray powder diffractometry as complementary techniques in characterizing clay size fraction of kaolin

open access: yesJournal of Applied Sciences and Environmental Management, 2005
This study aimed at demonstrating complementary roles offered by both Fourier transform infrared (FTIR) spectrophotometry and x-ray powder diffraction (XRPD) techniques in characterizing clay size fraction of kaolins.

Single-crystal x-ray diffraction structures of covalent organic frameworks

open access: yesScience, 2018
Covalent organic frameworks writ large Covalent organic framework (COF) materials have been difficult to characterize structurally and to exploit because they tend to form powders or amorphous materials. Ma et al.

Diffractive Physics [PDF]

open access: yesProceedings of Sixth International Conference on Quarks and Nuclear Physics — PoS(QNP2012), 2012
`Soft' high-energy interactions are clearly important in pp collisions. Indeed, these events are dominant by many orders of magnitude, and about 40% are of diffractive origin; that is, due to elastic scattering or proton dissociation. Moreover, soft interactions unavoidably give an underlying component to the rare `hard' events, from which we hope to ...

Low-frequency plane wave diffraction on a two-layer grating [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2004
In this paper the problem of TE and TM plane wave diffraction from a two-layer grating in low-frequency case is presented. The problem is solved using the network model.

Aperiodic order and pure point diffraction [PDF]

open access: yes, 2008
We give a leisurely introduction into mathematical diffraction theory with a focus on pure point diffraction. In particular, we discuss various characterisations of pure point diffraction and common models arising from cut and project schemes. We finish with a list of open problems.

A QCD analysis of ZEUS diffractive data [PDF]

open access: yesNucl.Phys.B831:1-25,2010, 2009
ZEUS inclusive diffractive cross-section measurements have been used in a DGLAP next-to-leading-order QCD analysis to extract the diffractive parton distribution functions. Data on diffractive dijet production in deep inelastic scattering have also been included to costrain the gluon density.

Tuning structural modulation and magnetic properties in metal–organic coordination polymers [CH3NH3]CoxNi1−x(HCOO)3

open access: yesIUCrJ
Three solid solutions of [CH3NH3]CoxNi1−x(HCOO)3, with x = 0.25 (1), x = 0.50 (2) and x = 0.75 (3), were synthesized and their nuclear structures and magnetic properties were characterized using single-crystal neutron diffraction and magnetization ...

Analysis of Current Distributions and Radar Cross Sections of Line Source Scattering from Impedance Strip by Fractional Derivative Method

open access: yesAdvanced Electromagnetics, 2019
In this paper, we have studied the analysis of current distributions and radar cross sections of line source scattering from impedance strip. The problem was solved with fractional derivative method previously.
