A multichannel far-infrared laser-based POlarimeter-INTerferometer (POINT) system utilizing the three-wave technique is under development for current density and electron density profile measurements in the EAST tokamak. Novel molybdenum retro-reflectors are mounted in the inside wall for the double-pass optical arrangement. A Digital Phase Detector with 250 kHz bandwidth, which will provide re...

Rotation axes were calculated during active head movements using a motion analysis system. The mean rotation axis for 1 Hz head pitch when seated was posterior (6 mm) and inferior (21 mm) to the interaural axis, shifting 16 mm downwards when standing. During seated 2 Hz head pitch the rotation axis was close to the interaural axis, shifting downwards 15 mm when standing. This downward shift sug...

In this paper the implementation of the SVD{updating algorithm using orthonormal { rotations is presented. An orthonormal {rotation is a rotation by an angle of a given set of {rotation angles (e.g. the angles i = arctan2 ?i) which are choosen such that the rotation can be implemented by a small amount of shift{add operations. A version of the SVD{updating algorithm is used where all computatio...

Co-current central toroidal rotation has been observed in Alcator C-Mod plasmas with on-axis ICRF heating. The rotation velocity increases with plasma stored energy and decreases with plasma current. Very similar behavior has been seen during Ohmic H-modes, which suggests that the rotation, generated in the absence of an external momentum source, is not principally an ICRF effect. A scan of the...

Despite extensive surveys of extragalactic TeV gamma-ray candidates only 3 sources have so far been detected. All three are northern hemisphere objects and all three are low-redshift X-ray selected BL Lacs (XBLs). In this paper we present the results of observations of the three nearest southern hemisphere XBLs (PKS0548−322, PKS2005−489 and PKS2155−304) with the CANGAROO 3.8m imaging telescope....

Yet each in itself – this was the uncanny, the antiorganic, the life-denying character of them all – each of them was absolutely symmetrical, icily regular in form. They were too regular, as substance adapted to life never was to this degree – the living principle shuddered at this perfect precision, found it deathly, the very marrow of death – Hans Castorp felt he understood now the reason why...

The precise rotation of suspended cells is one of the many fundamental manipulations used in a wide range of biotechnological applications such as cell injection and enucleation in nuclear transfer (NT) cloning. Noticeably scarce among the existing rotation techniques is the three-dimensional (3D) rotation of cells on a single chip. Here we present an alternating current (ac) induced electric f...

This paper addresses the problem of aerial image matching. We analyze existing approaches to this problem and show that, though the modern algorithms cope with the task quite well, their results are deteriorated in case of low overlap and significant rotation angle between the images. A two-stage feature-based image matching scheme is presented. It is shown that preliminary stage of simplified ...

A total of forty consecutive patients suffering from recurrent traumatic anterior shoulder instability underwent stabilisation with a glenoid based inferior capsular shift. The patients were followed up prospectively by an independent observer (JM) using the Constant-Murley score and objective evaluation of shoulder movement and strength with an isometric dynamometer. The mean follow-up period ...

The theory of optical activity presented in an earlier paper has been applied to helical structures, obtaining a compact formula for the residue rotation [ m ' ] ^ . In particular, the theory has been applied to the a-helix, and this theory consists of two parts: firstly the calculation of the magnitude and orientation of the polarisability tensor ellipsoid of the peptide residue from the locat...
