X-ray Debye-Waller factor measurements of solid 3He and 4He X-ray synchrotron radiation was used to measure Debye-Waller factors of helium crystals for both He and He in both hcp and fcc phases. To our knowledge, th... DA Arms,RS Shah,RO Simmons - 《Physical Review B》 被引量: 16...

A second round of analysis, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was performed as the fit indices of the initial CFA were not satisfactory. Results A sample of 202 physiotherapists and 97 physiotherapy students completed the survey. The second round of analysis...
I'm trying to do a HW involving the Darwin Term in the fine structure of hydrogen. I'm given that the perturbation from the Darwin term is equal to (times a constant factor which I'll ignore), V_D = [p_i,[p_i, \frac{e^2}{r}]] = e^2\vec{p}^2\frac{1}{r} -2e^2\...
‘solved’ structure, and then of its inverted equivalent, will give a lower R-factor for the correct enantiomer. However, a better strategy is to include an enantio-selective parameter into the least-squares refinement as a variable. Thus, Flack10expressed the actual structure factor of a ...
Fig. 1: Whole-brain functional connectivity is heterogeneous and not fully explained by any factor. a Whole-brain structural and functional connectivity data from the HCP dataset. b We used a series of dynamic, topological, and geometric models to transform sparse SC matrices into fully-weighted ...
The dMRI scan was conducted on a Siemens 3T Skyra scanner using a 2D spin-echo single-shot multiband echo-planar imaging sequence with a multiband factor of 3 and monopolar gradient pulse. The spatial resolution was 1.25 mm isotropic (repetition time (TR) = 5,500 ms, time to ...
The plot between ln (α.hν) versus ln (hν-Eg) is showed inFig. 3. It shows a straight line, where the slope is the power factor “m” which indicates the transition mode. The value m is equal to 0.49 which is approximately the same as that used in the literature. ...
QED Predictions of fine structure constant and g-factor Hi, I know QED is one of the most tested theories in all of science (and one of the most accurate) but I wanted to know if it disagreed at ALL with its predicted values of both http://en.wikipedia.org/wiki/Fine_structure_constan...
