Hong Kong Courts' Jurisdiction to Enforce Intellectual Property Rights Infringed By Internet Contents

This article considers jurisdictional issues arising when a local resident's intellectual property rights are infringed by Internet contents uploaded overseas. It considers the implications of the double actionability rule in such cases, and questions the view that local courts do not have jurisdiction to enforce foreign intellectual property rights. The article outlines the jurisdictional rules relating to Order 11 of the Rules of the High Court, discusses the application of the rules to cases involving IP rights and explores how the borderless nature of the Internet impacts on the application.published_or_final_versio

Remedies Against Telephone Tapping by the Government

Telephone tapping, a measure adopted by law enforcement agencies for the prevention and detection of crime, is carried out under section 33 of the Telecommunications Ordinance. However, the section does not pass the forseeability test required for it to be regarded as 'law'. The present practice of telephone tapping violates the right to privacy and to freedom of expression guaranteed by the Basic Law. The Personal Data (Privacy) Ordinance, which may be invoked by persons suspecting their telephones to have been tapped, has limitations. These people stand a better chance by relying on the Hong Kong Bill of Rights Ordinance. Accordingly, to avoid the courts being landed with the invidious task of either rendering the rights in question a nullity or denying law enforcement agencies a necessary tool, the Hong Kong Special Administrative Region (HKSAR) Government should take immediate action to enact legislation along the lines recommended by the Law Reform Commission in 1996.published_or_final_versio

Enhanced distance-based location management of mobile communication systems using a cell coordinates approach

In managing the locations of mobile users in mobile communication systems, the distance-based strategy has been proven to have better performance than other dynamic strategies, but is difficult to implement. In this paper, a simple approach is introduced to implement the distance-based strategy by using the cell coordinates in calculating the physical distance traveled. This approach has the advantages of being independent of the size, shape, and distribution of cells, as well as catering for the direction of movement in addition to the speed of each mobile terminal. An enhanced distance-based location management strategy is proposed to dynamically adjust the size and shape of location area for each individual mobile terminal according to the current speed and direction of movement. It can reduce the location management signaling traffic of the distance-based strategy by half when mobile terminals have predictable directions of movement. Three types of location updating schemes are discussed, namely, Circular Location Area, Optimal Location Area, and Elliptic Location Area. Paging schemes using searching techniques such as expanding distance search based on the last reported location and based on the predicted location, and expanding direction search are also explored to further reduce paging signal traffic by partitioning location areas into paging areas.published_or_final_versio

Recursive-Based PCG Methods for Toeplitz Systems with Nonnegative Generating Functions

In this paper, we consider the solutions of symmetric positive definite, but ill-conditioned, Toeplitz systems An x = b. Here we propose to solve the system by the recursive-based preconditioned conjugate gradient method. The idea is to use the inverse of Am (the principal submatrix of An with the Gohberg--Semencul formula as a preconditioner for An. The inverse of Am can be generated recursively by using the formula until m is small enough. The construction of the preconditioners requires only the entries of An and does not require the explicit knowledge of the generating function f of An. We show that if f is a nonnegative, bounded, and piecewise continuous even function with a finite number of zeros of even order, the spectra of the preconditioned matrices are uniformly bounded except for a fixed number of outliers. Hence the conjugate gradient method, when applied to solving the preconditioned system, converges very quickly. Numerical results are included to illustrate the effectiveness of our approach.published_or_final_versio

Does upgrade to tri-ventricular pacemaker improve long-term clinical response in non-responders to biventricular cardiac resynchronization therapy?

Up to one third of patients with biventricular (BiV) cardiac resynchronization therapy (CRT) are non-responders.1 § Greater clinical response to CRT has been shown in patients given TriV CRT compared to BiV CRT as de novo device therapy. 2 This abstract investigates if upgrade to TriV CRT in non-responders to BiV CRT will improve long-term clinical outcom

Effect of ZnO surface defects on efficiency and stability of ZnO-based perovskite solar cells

ZnO as an alternative electron transport layer (ETL) material for perovskite solar cell applications has drawn increasing research interest due to its comparable energy levels to TiO2, relatively high electron mobility, as well as its feasibility to be processed at low temperatures for potential applications in flexible devices. Nevertheless, ZnO based perovskite devices usually exhibit inferior performance and severe stability drawbacks which are related to the surface defects of ZnO ETL. In this study, to investigate the correlation between ZnO defect composition and resulting device performance, different approaches of preparing ZnO ETL are compared in terms of the perovskite morphology and device performance. In addition, direct manipulations of ZnO surface defects are performed by various surface treatments, and the photovoltaic performance of devices with ZnO ETL subjected to different surface treatments is compared. Surface modification of ZnO ETL by ethanolamine (EA) is demonstrated to efficiently enhance the photovoltaic performance of resulting ZnO based devices. © (2017) COPYRIGHT Societypublished_or_final_versio

Pixel-to-pixel fiber-coupled emissive micro-light-emitting diode arrays

We report on an integrated fiber-coupled bi-linear micro-light-emitting diode array, serving as a portable microdisplay system. The fiber bundle transforms the bi-linearly arranged optical signals from the emissive array into a 6-by-8 pixel microdisplay, offering a crisp and clear optical output. The pixel-to-pixel coupling arrangement ensures optical coupling efficiency. Due to the narrow acceptance cones of optical fibers, individual pixels can be well resolved with minimal crosstalk. The performance and functionality of this optical system is fully evaluated. A model to determine the fiber-coupling efficiency was constructed; it was found that the simulated results compare well with the measured data.published_or_final_versio
