– The phase shift of matter wave due to the Earth’s rotation and gravity has been demonstrated in the neutron-interferometry experiments where the Bragg reflection of the neutron wave from crystals is used to form a closed path. In the literature, the rotationinduced phase shift is ascribed to an extra energy term associated with angular momentum in the Hamiltonian. In this investigation, based...

This paper proposes a high-accuracy rotation estimation algorithm using 1D Phase-Only Correlation (POC). In general, the rotation angle between two images is estimated as follows: (i) convert the image rotation into the image shift by polar mappings of the amplitude spectra of images, and (ii) estimate the translational displacement between the polar mappings to obtain the rotation angle. The p...

In this paper, I reviewed comprehensively the structure and operation of closed-loop IFOGs, Feedback Erbium-doped fiber amplifier (EFDA) FOGs, called FE-FOG. The procedure of finding the Sagnac shift for closed-loop IFOG has been studied. The signal processing in the closed-loop IFOG was simulated using PSCAD software. In the closed-loop IFOG, the phase shift was derived through frequent use of...

BIRD's eye view: Adding periodic BIRD J-refocusing (BIRD=bilinear rotation decoupling) to data acquisition in an HSQC experiment causes broadband homonuclear decoupling, giving a single signal for each proton chemical shift. This pure shift method improves both resolution and signal-to-noise ratio, without the need for special data processing.

BACKGROUND The latest version of the navigation system for anterior cruciate ligament (ACL) reconstruction has the supplementary ability to assess knee stability before and after ACL reconstruction. In this study, we compared navigation data between clinical grades in ACL-deficient knees and also analyzed correlation between clinical grading and navigation data. METHODS 150 ACL deficient knee...

A technique for obtaining shift, rotation and scale invariant signatures for two dimensional contours in images is proposed and demonstrated. The technique is based upon a measure of the degree to which the local tangent estimate at each point in the contour is consistent with having been generated by a shift, rotation or scale invariant function. An invariance factor is calculated at each poin...

-The coordinate rotation digital computer (CORDIC) algorithm is widely used in various technological fields such as digital signal processing (DSP), biomedical signal processing, robotics, communication systems, image processing etc. Due to ease of simple shift and add operations, the use of CORDIC based systems is increasing drastically. In this paper, some CORDIC based applications have been ...

We examine the itinerary of 0 ∈ S = R/Z under the rotation by α ∈ R\Q. The motivating question is: if we are given only the itinerary of 0 relative to I ⊂ S, a finite union of closed intervals, can we recover α and I? We prove that the itineraries do determine α and I up to certain equivalences. Then we present elementary methods for finding α and I. Moreover, if g : S → S is a C, orientation p...

BACKGROUND Right thoracic curvature, rib cage deformities and aortic left shift are features of adolescent idiopathic scoliosis that are correlated with each other. We recently reported that disturbance of ribcage development results in progressive thoracic scoliosis in mice. Recently, it has been confirmed that the normal spine exhibits right thoracic curvature and rib cage deformities and tha...
