photoelectron spectraThe measured Kβ emission bands of Ga and As in GaAs, GaP, and the X-Ray and UV photoelectron spectra of CaAs, GaP, (Ga XAl 1-X) As have been co The comparison of X-ray bands and the X-ray photoelectron spectra gives information on the hybridisation state and the...
However, measurements of the power density spectrum are modified by the effects of deadtime in X-ray detectors. In this work, we focus on the Proportional Counter Array (PCA) instrument of the Rossi X-ray Timing Explorer (RXTE), an orbiting observatory that offers fast, microsecond-level ...
As there is no firm detection of such transients, we place constraints on the free zone solid angle at most a few times of the solid angle of the short gamma-ray burst jet. The event rate density of these X-ray transients is around a few tens of $m Gpc^{-3}yr^{-1}$ for ...
We have used x-ray photoelectron spectroscopy to determine the chemical elements present on the tops, sidewalls, and bottoms of submicron metal features etched in a high density inductively coupled plasma source using Cl2/BCl3 gas mixtures. X-ray photoelectron spectroscopy analyses have shown that ...
Bone mineral density (BMD) was assessed by dual energy X-ray absorptiometry. A polymorphism in the fat mass and obesity-associated gene (FTO rs9939609) was used as an instrument in the Mendelian randomization analysis.ResultsThe genotype distribution of the FTO rs9939609 polymorphism was 61·1% ...
We examine YBa2Cu3O7-delta thin films grown by DC magnetron sputtering on SrTiO3 substrates by using x-ray double crystal diffraction, x-ray topography and SEM, etc. Various microstructural and compositional parameters of the specimens with higher and lower critical current density (J(c)) are ...
In this work, we present a fast and promising method to evaluate the natural durability of wood based on X-ray microdensitometry. Tested on beech and Scots... N Macchioni,S Palanti,P Rozenberg - 《Wood Science & Technology》 被引量: 25发表: 2007年 Investigation on wax-impregnated wood. ...

The study ) was determined by dual-energy X-ray absorptiometry. Anthropometric measurements were made, and calcium intake and physical activity were assessed. Heredity accounted for 22–42% of the variation in BMD of the children, depending on the skeletal site. Heritability for cortical BMD of ...
Significance: We have shown the clinical potential of phalangeal DXA measurements of aBMD and vBMD on a slot-scanning digital radiography system. 展开 关键词: Absorptiometry bone mineral density dual-energy osteoporosis X-ray DOI: 10.1109/TBME.2015.2447575 被引量: 3 ...
