Rectilinear texture warping for fast adaptive shadow mapping (2012)

Conventional shadow mapping relies on uniform sampling for producing hard shadow in an efficient manner. This approach trades image quality in favor of efficiency. A number of approaches improve upon shadow mapping by combining multiple shadow maps or using complex data structures to produce shadow maps with multiple resolutions. By sacrificing some performance, these adaptive methods produce shadows that closely match ground truth.
A Newly Developed Intelligent Variable Valve Timing System - Continuously Controlled Cam Phasing as Applied to a New 3 Liter Inline 6 Engine (1996)

<div class="htmlview paragraph">To meet the requirements for higher horsepower and torque as well as lower fuel consumption and emissions, we have developed a new “Intelligent Variable Valve Timing (VV-i)” system. It gives continuously variable intake cam phasing by up to 60 degrees crank angle (CA) . This system not only increases WOT output by optimizing intake valve closing timing but also reduces fuel consumption and NOx/ HC emissions under part load by increasing intake and exhaust valve overlap on 4 stroke Spark Ignited engines.</div> <div class="htmlview paragraph">VVT-i has been applied to optimize a new 3-liter inline 6 engine for higher torque and at the same time better fuel economy with continuous and wide-range cam phasing.</div>
Electric-arc-induced gratings in non-hydrogenated fibres: fabrication and high-temperature characterizations (2002)

Long-period fibre gratings are written in non-hydrogenated standard single-mode fibres, using electric discharge. We have obtained a transmitted spectrum with low insertion loss (<0.2 dB) and resonance peak isolation of -24 dB at 1545 nm. The model, based on coupled mode theory, predicts reasonably well the peak positions and isolations. We have performed very high temperature characterizations of the realized gratings, in the range 30-1200 °C. We have shown a specific spectral shift of the resonance peaks with temperature. We report a modal dependence of wavelength shift with temperature. Temperature annealing of the gratings, at 200, 400 and 600 °C show high thermal stability compared with CO2 and UV-induced ones, but annealing at 800 and 900 °C exhibit an irreversible spectral shift. The temperature sensitivity values are in good agreement with recently published works. These characterizations will help us to understand the writing mechanism of the grating by an electric discharge in standard single-mode fibres.
A Real‐Time Facial Expression Recognition System for Online Games (2008)

Multiplayer online games (MOGs) have become increasingly popular because of the opportunity they provide for collaboration, communication, and interaction. However, compared with ordinary human communication, MOG still has several limitations, especially in communication using facial expressions. Although detailed facial animation has already been achieved in a number of MOGs, players have to use text commands to control the expressions of avatars. In this paper, we propose an automatic expression recognition system that can be integrated into an MOG to control the facial expressions of avatars. To meet the specific requirements of such a system, a number of algorithms are studied, improved, and extended. In particular, Viola and Jones face‐detection method is extended to detect small‐scale key facial components; and fixed facial landmarks are used to reduce the computational load with little performance degradation in the recognition accuracy.

Nonhuman Primate Models for Evaluation of AIDS Therapy<sup>a</sup> (1990)

Infection of macaque monkeys with simian immunodeficiency virus (SIV) has been established as an excellent animal model system for studying the pathogenesis of an HIV-like virus and for evaluating newly developed antiretroviral drugs and vaccines. Based on their genetic, antigenic, and biologic properties, the simian immunodeficiency viruses are the closest known relatives of the human AIDS viruses, and experimental infection of macaque monkeys results in a disease that is remarkably similar to human AIDS. Infected macaques show diarrhea, weight loss, hematologic abnormalities including lymphopenia and thrombocytopenia, lymphadenopathy/lymphoid hyperplasia that progresses to lymphoid depletion, immunosuppression with marked reduction in CD4+ cells and in the CD4+/CD8+ cell ratio, and opportunistic infections. A majority of such macaques die from an AIDS-like disease within one to three years of infection. An acutely lethal variant of SIV has been identified that results in death in susceptible macaques within 7-12 days of infection. Preliminary prophylactic treatment trials with AZT in macaque monkeys exposed to the acutely lethal SIV variant indicate that some protection is provided when AZT treatment is initiated within 24 hours of virus exposure. Other studies with the more chronic SIV infection model, however, failed to show any prophylactic efficacy of CS-87, AZT, D4T, or FDT.

「悲情城市」是怎樣「打造」的? 天水圍的空間政治 (2011)

位於香港新界西北部的新市鎮天水圍，數年來由於貧窮人口眾多、失業率和青少年犯罪率高企及偶爾發生的倫常慘劇而被傳媒形容為「悲情城市」，這早已是老生常談。對天水圍的種種家庭及社會問題，不少社會人士及專家學者亦已有精闢詳盡的分析，天水圍議題似乎已成明日黃花。\n2010年12月，《南華早報》一篇題為 “Colonial deal built 'City of Sadness”的報道，卻重新令天水圍成為焦點。該篇報導提到港英殖民政府在1982年發展天水圍新市鎮時，曾經與發展商Mightycity Company (現由長實集團及華潤創業持有) 簽署備忘協議，限制在天水圍發展商業設施，以保證不會威脅Mightycity發展的私人商業設施。政府又以高於市場價格向發展商買回面積接近500公頃的魚塘和農地，然後再與發展商共同開發。從表面上看，這似乎又一次證明「官商勾結」在香港的長期存在，或為嶺南大學羅永生教授提出的「勾結式殖民主義」(Collaborative Colonialism)提出新例證。但若細心分析，不難發現這裡牽涉的再一次是關乎權貴與弱勢者的空間(space)鬥爭，是香港成為全面都市化社會的案例之一。

Pareto-optimal resilient controller placement in SDN-based core networks (2013)

With the introduction of Software Defined Networking (SDN), the concept of an external and optionally centralized network control plane, i.e. controller, is drawing the attention of researchers and industry. A particularly important task in the SDN context is the placement of such external resources in the network. In this paper, we discuss important aspects of the controller placement problem with a focus on SDN-based core networks, including different types of resilience and failure tolerance. When several performance and resilience metrics are considered, there is usually no single best controller placement solution, but a trade-off between these metrics. We introduce our framework for resilient Pareto-based Optimal COntroller-placement (POCO) that provides the operator of a network with all Pareto-optimal placements. The ideas and mechanisms are illustrated using the Internet2 OS3E topology and further evaluated on more than 140 topologies of the Topology Zoo. In particular, our findings reveal that for most of the topologies more than 20% of all nodes need to be controllers to assure a continuous connection of all nodes to one of the controllers in any arbitrary double link or node failure scenario.
The Relationship between Rubisco Activity and Photosynthesis in Apple Leaves with Different Nitrogen Content (1997)

Based on the curvilinear relationship between carboxylation efficiency and leaf N in apple leaves, we hypothesized that deactivation of Rubisco accounts for the lack of response of photosynthesis to increasing leaf N under high N supply. A wide range of leaf N content (from 1.0 to 5.0 g·m –2 ) was achieved by fertigating bench-grafted Fuji/M26 apple trees for 6 weeks with different N concentrations using a modified Hoagland solution. Analysis of photosynthesis in response to intercellular CO 2 under both 21% and 2% O 2 indicated that photosynthesis at ambient CO 2 was mainly determined by the activity of Rubisco. Measurements of Rubisco activity revealed that initial Rubisco activity increased with leaf N up to 3.0 g·m –2 , then leveled off with further rise in leaf N, whereas total Rubisco activity increased linearly with increasing leaf N throughout the leaf N range. As a result, Rubisco activation state decreased with increasing leaf N. Photosynthesis at ambient CO 2 and carboxylation efficiency were both linearly correlated with initial Rubisco activity, but showed curvilinear relationships with total Rubisco activity and leaf N. As leaf N increased, photosynthetic nitrogen use efficiency declined with decreasing Rubisco activation state.
Quantitative Determination of the Speciation of Surface Vanadium Oxides and Their Catalytic Activity (2006)

A quantitative method based on UV-vis diffuse reflectance spectroscopy (DRS) was developed that allows determination of the fraction of monomeric and polymeric VO(x) species that are present in vanadate materials. This new quantitative method allows determination of the distribution of monomeric and polymeric surface VO(x) species present in dehydrated supported V(2)O(5)/SiO(2), V(2)O(5)/Al(2)O(3), and V(2)O(5)/ZrO(2) catalysts below monolayer surface coverage when V(2)O(5) nanoparticles are not present. Isolated surface VO(x) species are exclusively present at low surface vanadia coverage on all the dehydrated oxide supports. However, polymeric surface VO(x) species are also present on the dehydrated Al(2)O(3) and ZrO(2) supports at intermediate surface coverage and the polymeric chains are the dominant surface vanadia species at monolayer surface coverage. The propane oxidative dehydrogenation (ODH) turnover frequency (TOF) values are essentially indistinguishable for the isolated and polymeric surface VO(x) species on the same oxide support, and are also not affected by the Brønsted acidity or reducibility of the surface VO(x) species. The propane ODH TOF, however, varies by more than an order of magnitude with the specific oxide support (ZrO(2) > Al(2)O(3) >> SiO(2)) for both the isolated and polymeric surface VO(x) species. These new findings reveal that the support cation is a potent ligand that directly influences the reactivity of the bridging V-O-support bond, the catalytic active site, by controlling its basic character with the support electronegativity. These new fundamental insights about polymerization extent of surface vanadia species on SiO(2), Al(2)O(3), and ZrO(2) are also applicable to other supported vanadia catalysts (e.g., CeO(2), TiO(2), Nb(2)O(5)) as well as other supported metal oxide (e.g., CrO(3), MoO(3), WO(3)) catalyst systems.
Literatura, Cine y Publicidad (2010)

espanolEn los ultimos anos estamos asistiendo a un incremento en la relacion publicitaria entre la literatura y el cine debido, seguramente, al prestigio creciente y a la repercusion mediatica de estos dos ambitos de la cultura. Para comprobar lo afirmado anteriormente, en este articulo hemos analizado una serie de anuncios, difundidos en los ultimos cinco anos, en los que se ha recurrido a esta alianza entre la literatura y el cine para conseguir ofrecer una imagen favorable de los productos anunciados y que refleja, a su vez, los nuevos habitos de promocion editorial de las novelas adaptadas al cine. El corpus analizado se ha constituido a partir de publicidad, tanto grafica como audiovisual. En el caso de los espots publicitarios audiovisuales se han tomado de las correspondientes paginas web de las marcas, o de las selecciones que de anuncios diversos existen en internet. El estudio tambien ha considerado como base de analisis las revistas literarias Que leer y Mercurio; las revistas de cine de mayor tirada nacional, Fotogramas y Cinemania; y los suplementos literarios de los principales periodicos nacionales (El Pais, ABC, y El Mundo). El seguimiento de la publicidad durante este periodo nos ha permitido concluir una serie de funciones -repetidas en el tiempo- que vinculan la literatura, el cine y la publicidad en formatos hibridos novedosos. Estos abren, a nuestro entender, un campo de investigacion de gran interes para los estudiosos de cualquiera de las tres disciplinas, asi como los profesionales de la edicion. Este cruce de vias, en definitiva, viene a demostrar la vitalidad creativa de un segmento de la comunicacion persuasiva, la publicidad, que no dejara nunca de innovar ni de sorprender a analistas y consumidores EnglishIn recent years we observe an increase in the relationship between literature and cinema advertising because of the prestige of these two areas of culture. To verify this, we analyzed a series of announcements in this article, released in the last five years, which has taken such a union between literature and film to promote the image of the products advertised. The analysis was conducted based on advertising, both graphic and audiovisual. In the case of audiovisual commercials are taken from the websites of the brands or selections that are online. The study also analyzed the literary magazine that read and Mercury, the picture magazines, and Movie Stills and major national newspapers (El Pais, ABC and El Mundo). The monitoring of advertising during this time has allowed us to conclude a series of functions linking literature, film, new forms of advertising. These are of great interest to students of all three disciplines and the world of publishing. This fusion ultimately proves the vitality of a part of persuasive communication, advertising, which is always innovate and surprise.
Indoors Data Communications using Airborne Ultrasound (2006)

We have tested an indoor data communications system based on ultrasound which is the core of an indoor positioning system. Unlike most other such systems, it relies on ultrasound alone. No radio or infrared channel nor any tether is used for communication. The main hardware components are a tag and a detector. The detector has an Ethernet interface and uses digital signal processing to cope with the acoustic environment and its noise, reverberations and Doppler shift. The attainable range is 10-20 meters and, by making a comparison with the range for speech, we find that the range predictions are consistent with our experience. The channel efficiency of the system is found to be somewhat less than for human speech which also has to deal with a similar environment. This comparison is done by using the Shannon channel capacity theorem.
Specifications and measurements of service areas coverage for mobile radio systems (2002)

This paper briefly reviews the behavior of mobile radio signals and the performance of radio mobile systems associated with its service area coverage. Two methods of specifying the area coverage are defined. With the area coverage clearly defined, together with the definitions of shadow areas and the associated integrating time, the area coverage of any mobile radio system can be clearly specified. The specifications used for an actual system are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Glow discharge amorphous silicon. Final report of innovative research program subtask, December 1977--September 1978 (1978)

The primary objective of this research was to build, test, and evaluate the glow discharge amorphous silicon facility. Amorphous silicon films deposited by our glow discharge technique were evaluated optically and electrically and found comparable to those from other laboratories. Analysis of previous heterojunction measurements suggests a multistep tunneling mechanism in the IT0/Si diode.
AWRT: A Recommender System for Improving Revisiting Web Pages (2013)

Web revisit has become one of the dominant phenomena in the web. Nevertheless, standard revisit features in typical web browsers currently do not significantly support this phenomenon. Various efforts, therefore, have been carried out to provide web users with approaches for facilitating web revisit. However, these approaches burden users with management tasks such as flagging and marking. This paper presents a novel approach, called the Adaptive Web Revisit Tool (AWRT), which helps facilitate revisiting web pages without involving users with any actions. In a similar way to the recommendation systems of well-known e-commerce websites, pages that are most likely to be revisited are adaptively recommended to users based on three attributes: frequency of visits, relation to current web page, and time per visit. AWRT consists of three main features: most visited pages (MVP), related pages (RP) and browsing behavior pages (BBP). AWRT was evaluated in terms of efficiency and usability using logging files and a satisfaction questionnaire. The results demonstrated an overall high rate of revisiting using AWRT when compared to a typical web browser i.e. Internet Explorer (IE) and a high users' satisfaction was demonstrated as well. Therefore, incorporating recommendation systems and adaptive techniques such AWRT can significantly improve web revisit.
Syntheses and Characterization of Microporous Coordination Polymers with Open Frameworks (2002)

The reactions of porous two-dimensional copper dicarboxylates (copper fumarate, copper terephthalate, copper styrene dicarboxylate, and copper 4,4‘-biphenyl dicarboxylate) with triethylenediamine as a pillar ligand yielded porous three-dimensional coordination polymers. The characterization by gas adsorption indicated that these coordination polymers have uniform micropores, high porosities, and gas adsorption capacities. These properties depend on the kind of dicarboxylate, and by changing it, the porosity and the pore size of the polymer can be controlled. The measurements of methane adsorption isotherms revealed that all coordination polymers have methane adsorption capacities, and especially, polymers synthesized from copper styrene dicarboxylate and copper 4,4‘-biphenyl dicarboxylate, which have ideal pore sizes and distributions for methane adsorption, have higher methane adsorption capacities than that of the theoretical maximum for activated carbon.
SID-1 is a dsRNA-selective dsRNA-gated channel (2011)

Systemic RNAi in Caenorhabditis elegans requires the widely conserved transmembrane protein SID-1 to transport RNAi silencing signals between cells. When expressed in Drosophila S2 cells, C. elegans SID-1 enables passive dsRNA uptake from the culture medium, suggesting that SID-1 functions as a channel for the transport of double-stranded RNA (dsRNA). Here we show that nucleic acid transport by SID-1 is specific for dsRNA and that addition of dsRNA to SID-1 expressing cells results in changes in membrane conductance, which indicate that SID-1 is a dsRNA gated channel protein. Consistent with passive bidirectional transport, we find that the RNA induced silencing complex (RISC) is required to prevent the export of imported dsRNA and that retention of dsRNA by RISC does not seem to involve processing of retained dsRNA into siRNAs. Finally, we show that mimics of natural molecules that contain both single- and double-stranded dsRNA, such as hairpin RNA and pre-microRNA, can be transported by SID-1. These findings provide insight into the nature of potential endogenous RNA signaling molecules in animals.
Code Injection Attacks on HTML5-based Mobile Apps (2014)

Due to the portability advantage, HTML5-based mobile apps are getting more and more popular.Unfortunately, the web technology used by HTML5-based mobile apps has a dangerous feature, which allows data and code to be mixed together, making code injection attacks possible. In this paper, we have conducted a systematic study on this risk in HTML5-based mobile apps. We found a new form of code injection attack, which inherits the fundamental cause of Cross-Site Scripting attack~(XSS), but it uses many more channels to inject code than XSS. These channels, unique to mobile devices, include Contact, SMS, Barcode, MP3, etc. To assess the prevalence of the code injection vulnerability in HTML5-based mobile apps, we have developed a vulnerability detection tool to analyze 15,510 PhoneGap apps collected from Google Play. 478 apps are flagged as vulnerable, with only 2.30\% false-positive rate. We have also implemented a prototype called NoInjection as a Patch to PhoneGap in Android to defend against the attack.
Key players in pancreatic cancer-stroma interaction: Cancer-associated fibroblasts, endothelial and inflammatory cells (2016)

Pancreatic cancer (PC) is the most aggressive type of common cancers, and in 2014, nearly 40000 patients died from the disease in the United States. Pancreatic ductal adenocarcinoma, which accounts for the majority of PC cases, is characterized by an intense stromal desmoplastic reaction surrounding the cancer cells. Cancer-associated fibroblasts (CAFs) are the main effector cells in the desmoplastic reaction, and pancreatic stellate cells are the most important source of CAFs. However, other important components of the PC stroma are inflammatory cells and endothelial cells. The aim of this review is to describe the complex interplay between PC cells and the cellular and non-cellular components of the tumour stroma. Published data have indicated that the desmoplastic stroma protects PC cells against chemotherapy and radiation therapy and that it might promote the proliferation and migration of PC cells. However, in animal studies, experimental depletion of the desmoplastic stroma and CAFs has led to more aggressive cancers. Hence, the precise role of the tumour stroma in PC remains to be elucidated. However, it is likely that a context-dependent therapeutic modification, rather than pure depletion, of the PC stroma holds potential for the development of new treatment strategies for PC patients.
