In this paper the author presents an overview of the evolution of proton-proton spin physics over the past quarter century and describes recent work on interpreting high energy polarization effects in a constituent scattering model. INTRODUCTORY REMARKS It is with considerable trepidation that I take the floor to speak to you today about advances in spin physics because I recall having been ask...

We present a fully relativistic analysis of Bessel beams revealing some noteworthy features that are not explicit in the standard description. It is shown that there is a reference frame in which the field takes a particularly simple form, the wave appearing to rotate in circles. The concepts of polarization and angular momentum for Bessel beams is also reanalyzed.

We present the findings for the quantum conductance staircase of holes that is caused by the edge channels in the ultra-shallow p-type silicon quantum well (Si-QW), 2 nm, confined by the δ-barriers heavily doped with boron on the n-type Si (100) surface. This longitudinal quantum conductance staircase, Gxx, is revealed by the voltage applied to the Hall contacts, Vxy, to a maximum of 2 4e h 2 2...

Abstract. We study the statistics of column-convex lattice animals resulting from the stacking of squares on a single or double staircase. We obtain exact expressions for the number of animals with a given length and area, their mean length and their mean height. These objects are closely related to Fibonacci numbers. On a single staircase, the total number of animals with area k is given by th...

We derive self-reciprocity properties for a number of polyomino generating functions, including several families of column-convex polygons, three-choice polygons and staircase polygons with a staircase hole. In so doing, we establish a connection between the reciprocity results known to combinatorialists and the inversion relations used by physicists to solve models in statistical mechanics. Fo...

A stereo vision system for detecting 3D-objects is presented. The method uses a pair of externally uncalibrated cameras and is able t o detect objects located on a staircase. Detection is based on differencing stereo pair images, where a warping transform is used to overlay the left onto the right image, and vice versa. The 3D camera positions are obtained through model t~ased pose estimation a...

We report on peculiar magnetic-field-induced metamagnetic transitions in the antiferromagnetic itinerant-electron compound La0·9Ce0·1Fe12B6. Below 8 K, first magnetization curves display multiple steep jumps generating a staircase-like shape. Whereas of La0·9Ce0·1Fe12B6 varies smoothly with external applied magnetic field at T ≥ K. further show that this staircase effect is extremely sensitive ...

Tension duration curves recorded during isometric contractions of toad ventricular strips were studied under a variety of conditions. Changes recorded in these curves during inotropic responses could be divided into two classes: (a) those in which the time required to reach peak tension (t(p)) was decreased and the twitch duration shortened. (b) those in which t(p) was either unaltered or incre...
