WIPO Panels’ interpretation of the Uniform Dispute Resolution Policy (UDRP) three-prong test

The Uniform Dispute Resolution Policy (UDRP) is a unique process that resolves domain name disputes effectively and inexpensively. This paper, through an analysis of the UDRP three-prong test, revealed that even though the UDRP affords a great degree of discretion to the WIPO Panels deciding any given case, there is some consistency and predictability inherent in the UDRP process.

The role of scale resolution versus inter-particle cohesive forces in two-fluid modeling of bubbling fluidization of Geldart A particles

Coarse grid simulations of Geldart A particles in bubbling fluidized beds using standard two-fluid (TF) models, where the constitutive laws are based on the homogeneity of sub-grid scale structures, have been demonstrated to be unsuccessful due to the existence of significant sub-grid scale heterogeneous structures. However, a definite consensus on the fundamental origin of the failure is still lacking. Some claim that the existence of significant inter-particle cohesive forces results in the sub-grid scale heterogeneous structures which takes the form of agglomerates or clusters; others claim that the inter-particle cohesive forces are not the dominant factor, and that the poor performance of TF models is primarily due to the fact that the grid sizes and the time step used in previous studies are too coarse to fully resolve the bubbling structure. To this end, a short overview is firstly presented to discuss the role of scale resolution and inter-particle cohesive force in two-fluid modeling of Geldart A particles; We then qualitatively explain, using a state-of-the-art discrete particle method, why the methods based on the existence of aggregates or clusters work quite well, although the sub-grid scale structure is not properly identified, that is, the sub-grid scale structure takes the form of a bubble-emulsion phase.     

Spontaneous Deracemization

Chirality can emerge spontaneously from racemizing samples in a remarkably efficient manner. The effect results from the stochastic generation of an excess of one enantiomer in the solid and subsequent amplification of the initial material to the bulk. In this review we shall give examples showing how this effect has proved to be an inspiration for the emergence of chirality from chiral materials, and even for the preparation of pharmaceutically important intermediates. While spontaneous deracemization should produce either enantiomer randomly, the kind of system that demonstrates the phenomenon is very prone to the induction of one handedness with extremely small quantities of chiral inducer, which makes the process exploitable in certain cases. This kind of deracemization is the epitome of the origin, transfer and amplification of chirality.     

Monte Carlo study of spatial resolution of the scintillation camera

The aim of this study was to evaluate the influence of different entrance surface treatments of the scintillator on the intrinsic spatial resolution of a scintillation camera.The primary scintillation light reflection on the entrance surface of a scintillator may be affected by the optical coating of the entrance surface,resulting in either spatial resolution or system detection efficiency degradation.A Monte Carlo simulation model,based on Geant4 codes,was developed in order to study the scintillation ligh...     

Analysis of PLR for Shared Switch Fabrics

A modular upgrade design for packet transport switch nodes is presented where packet loss is dramatically reduced by intra‐module and inter‐module buffer sharing. This modular design offers significant cost and power reduction in a high‐data‐rate system where buffers are highly costly and power‐greedy.     

Stabilized two-dimensional linewidth enhancement in direct laser lithography

In order to realize a small linewidth two-dimensional direct laser lithographic technique with enhanced resolution, we propose two apparatuses. The first one uses a polarizing beam splitter to separate a source beam into two output beams, and these two beams overlap on the focal point and make a narrow interferogram that sharpens the focused beam spot. The direction of the sharpened beam spot is controlled by a tilting mirror. This scheme is fast and easy to align. However, one serious problem, the interferogram shifting phenomenon, was observed during a long term fabrication. To obtain long term stability, we propose the second scheme that employs a calcite wave plate module attached to a motorized rotary motor. In this setup, the direction of the focused beam spot is controlled by the rotary motor.

Why the two-fluid model fails to predict the bed expansion characteristics of Geldart A particles in gas-fluidized beds: A tentative answer

It is well known that two-fluid models (TFMs) can successfully predict the hydrodynamics of Geldart B and D particles. However, up to now, TFM have failed to accurately describe the hydrodynamics of Geldart A particles inside bubbling gas-fluidized beds: Researchers have reported that bed expansions are over-predicted by as much as 70%. In this work we show—for the first time—that TFM can predict the correct bed expansion, without any artificial modifications, provided that a sufficiently fine grid size and small time step is used. This suggests that the previously reported failure of TFM is mainly due to the lack of scale resolution, and that from a modeling point of view there is no fundamental difference between Geldart A particles and Geldart B and D particles.
