In this article, we calculate the axial and the induced pseudoscalar formfactors GA(t = −Q ) and GP (t = −Q ) of the nucleons in the framework of the light-cone QCD sum-rules approach up to twist-6 three valence quark light-cone distribution amplitudes, and observe that the form-factors GA(t = −Q) and GP (t = −Q ) at intermediate and large momentum transfers with Q > 2GeV 2 have significant con...
OBJECTIVE The purpose of this investigation was to evaluate the factor structure and the internal consistency of the Eating Disorder Examination-Questionnaire (EDE-Q). METHOD The EDE-Q was administered to 203 women with bulimic symptoms, who were recruited from five Midwestern communities. RESULTS Acceptable levels of internal consistency were observed for the EDE-Q total score (alpha = .90...
The uncertainty of the beam quality conversion factor (k(Q,Q0)) of standard dosimetry of absorbed dose to water in external beam radiotherapy 12 (JSMP12) is determined by combining the uncertainty of each beam quality conversion factor calculated for each type of ionization chamber. However, there is no guarantee that ionization chambers of the same type have the same structure and thickness, s...
a power divider (pd)/ power combiner (pc) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (siw) technology is proposed. an siw cavity is designed to provide a high quality factor filtering response and an smd resistor is attached between two output ports to realize the high isolation. the value of the applied resistor is calculated by using the ...
In JLab Experiment E12-07-104 we intend to dramatically extend the reach of our understanding of a fundamental feature of the neutron; its magnetic form factor GnM . The elastic electromagnetic form factors(EEFFs) describe the distribution of charge and magnetization inside the nucleon at low Q and probe the quark structure at higher Q. This experiment is part of a broad program at JLab to meas...
Let n = pq > q be an rsa modulus. This note describes a lll-based method allowing to factor n given 2 log2 q contiguous bits of p, irrespective to their position. A second method is presented, which needs fewer bits but whose length depends on the position of the known bit pattern. Finally, we introduce a somewhat surprising ad hoc method where two different known bit chunks, totalling 3 2 log2...
High index dielectric nanostructure supports different types of resonant modes. However, it is very challenging to achieve high-Q factor in a single subwavelength nanoresonator due non-hermtian property the open system. Here, we present universal approach finding out series modes nonspherical nanocavity by exploring quasi-bound state continuum. Unlike conventional method relying on heavy comput...
Measurements of net ecosystem exchange (NEE), solar global radiation, photosynthetically active radiation (PAR) and meteorological parameters were carried out on a subtropical conifer plantation in China from 2013 to 2016. These observations used develop evaluate an empirical model gross primary production (GPP) (EMGPP) with 3-factor 2-factor models. Using model, the simulated hourly GPP values...
The performance of optical M-level (multi-level) amplitude shift keying (ASK) modulation is improved by directly using modulated optically injection-locked (OIL) semiconductor lasers. direct free-running and OIL lasers evaluated compared theoretically based on coupled-rate equation. We have found that can significantly improve the in terms signal eye opening Q-factor. Additionally, we Q-factor ...
