BACKGROUND Measuring range of movement is important in clinical shoulder assessment. Over the years, different techniques have been used to analyze upper limbs mobility. Smartphone image-based goniometer offers a noninvasive easy-to-use method of measuring arm abduction angle. However, the validity of this method has not been previously established. The purpose of this study was to investigate ...

Objective: Inclination of the first ray axis has been identified as a risk factor of bunion, but the actual orientation of a joint axis can only be quantified with motion analysis techniques. This investigation used a single-group regression design for the purpose of identifying a surrogate measure, or system of measurements, that could predict the orientation of the first ray axis. Methods: Th...

Super-Kamiokande uses neutrino-electron elastic scattering to measure the recoil electron spectrum and zenith-angle dependence of solar B neutrinos. SNO has measured the B neutrino–deuteron charged-current reaction rate. The elastic scattering rate, spectrum and zenith-angle dependence in conjunction with the charged-current reaction rate favors active neutrino oscillations at large mixing angl...

We proposed heterodyne angle deviation interferometry (HADI) for angle deviation measurements. The phase shift of an angular sensor (which can be a metal film or a surface plasmon resonance (SPR) prism) is proportional to the deviation angle of the test beam. The method has been demonstrated in bubble and speaker’s vibration measurements in this paper. In the speaker’s vibration measurement, th...

Background T1 mapping has great potential for diagnosing diffuse cardiomyopathies. Modified Look Locker Inversion Recovery (MOLLI) is a promising 2D SSFP technique to measure T1 differences between healthy and diseased states in cardiac tissue. However, this method has been found to provide variable T1 values at different flip angles. Here we develop an improved fitting algorithm which accounts...

A simple visual test was used to measure how much Listing's plane rotates as a function of the vergence angle. This test measured the elevation-dependent torsional disparity of horizontal and vertical lines during three tasks: vergence on a near target, vergence through prisms that remained fixed, and through prisms that rotated with eye elevation. Consistent with our previous search-coil measu...

purpose: to evaluate visual outcomes and intraocular pressure (iop) after single-site phacotrabeculectomy with mitomycin c in patients with senile cataract and primary open angle glaucoma (poag), pseudoexfoliative glaucoma (pxg), or chronic angle closure glaucoma (cacg). methods: in this retrospective study, patients older than 50 years who had significant cataracts (bcva £ 20/60) and uncontrol...

A 3.5 GHz OAM antenna with ±1 mode was designed and fabricated, the channel measurement in frequency domain used to measure full angle under indoor multipath scenarios. Then, modified probability density function of Gaussian distribution, Laplacian Von Mises distribution are establish full-angle statistical model. The fitting curve results well represent characteristics scenario.

Stage IVb sporangiophores of Phycomyces grow into the wind--the anemotropic response--and away from gravity--the geotropic response. A procedure has been designed to measure the equilibrium bend angle that results when the two stimuli are given simultaneously over a long period of time. This angle will be referred to as the anemogeotropic equilibrium angle. This measurement of a sensory respons...

We measure the local skew angle of the Poynting vector within a helically-phased, exp (il phi), beam using a Shack Hartmann wavefront sensor. It is the skew angle of the Poynting vector with respect to the beam axis that gives rise to the orbital angular momentum of a light beam. We confirm that this skew angle is l/kr, corresponding to an orbital angular momentum of l? per photon. Measurement ...
