Fine-grained information access in Virtual Organisations (2010)

Virtual organisations (VOs) in construction are highly dynamic in their composition and operability. Typically, information processing in such VOs takes place on a virtual platform which regulates the access of the VO members (subjects) to the digital information resources (objects) representing dynamic real-world subjects and objects. Their context information reflecting the current situation and viable to changes during processing is mapped to a context model. The selection of authorized operations may therefore depend on the actual status of this context model. Hence it is important to include the context model in authorization decisions to achieve a highly flexible authorization mechanism capable of handling the dynamics of Virtual Organisations. In addition, access can be restricted to parts of an object. However, current access control approaches based on the standard RBAC model or the extended ABAC model are still largely static, lacking the necessary dynamicity, flexibility and fine granularity required by construction VOs. In this paper we describe an approach for the realization of fine-grained context-aware access management, mapping the required dynamic VO behaviour in an ICT environment. With the help of a generic platform ontology acting as context model that describes the actors, resources and processes of a VO by combining features of the RBAC and ABAC models a fine-grained context-specific user support complemented with role-based business, access and representation profiles was achieved.
A Methodology for Deriving VoIP Equipment Impairment Factors for a Mixed NB/WB Context (2008)

This paper proposes a novel approach to quantifying the quality degradation of Voice over IP (VoIP) telephony in the presence of codec and network-related impairments. This approach differs from the baisc ITU-T E-Model for VoIP quality estimation in that it addresses mixed narrowband/wideband scenarios. It makes novel use of instrumental models and symbolic regression via Genetic Programming (GP) to enable the evolution of degradation models from a modest set of initial parameters. Here, a two-step approach has been used. First, values of impairment factors are derived using WB-PESQ as a reference model. Secondly, a GP based symbolic regression approach has been utilized to automatically evolve the functional form of equipment impairment factors from a set of variables. Very few a priori assumptions are made about the model structure. The effectiveness of the approach is demonstrated by a number of generated models which compare favorably with WB-PESQ and outperform the traditional E-Model in terms of prediction accuracy when compared using WB-PESQ. A significant advantage of the approach is that new models are easily generated to account for continuing evolution of the VoIP standards.
Lo que se dice: operador ostensivo metalingüístico (2007)

espanolLo que se dice es un operador metalinguistico, que apunta de forma ostensiva al contenido de la unidad seleccionada del codigo. Esta se presenta como la adecuada a la realidad que se designa. Aparece en tres contextos discursivos: introduciendo un complemento tematizado, focalizando cualquier funcion sintactica, o adelantandose a una conclusion denominativa. Esta unidad muestra la interrelacion entre el plano informativo y el enunciativo, apuntando a la necesidad de una descripcion multidimensional de las unidades del discurso. EnglishLo que se dice is a metalinguistic operator. It marks by ostension the meaning of the word chosen by the speaker. This word is the most suitable to the �designatum�. It appears in three discursive contexts: introducing the theme, focusing any syntactic function or with a conclusion. Lo que se dice shows the interaction between the information and the declaration, and reveals the need of a multidimensional description of discourse units.
Sentence compression beyond word deletion (2008)

In this paper we generalise the sentence compression task. Rather than simply shorten a sentence by deleting words or constituents, as in previous work, we rewrite it using additional operations such as substitution, reordering, and insertion. We present a new corpus that is suited to our task and a discriminative tree-totree transduction model that can naturally account for structural and lexical mismatches. The model incorporates a novel grammar extraction method, uses a language model for coherent output, and can be easily tuned to a wide range of compression specific loss functions.
The extent of surface contamination of retailed chickens with<i>Campylobacter jejuni</i>serogroups (1988)

Eighty-two chickens purchased at 11 retailers (supplied by 12 wholesalers) in the south of England were cultured for Campylobacter jejuni by a method involving total immersion. The organism was isolated from 22 (48%) of 46 fresh birds, 12 of 12 uneviscerated (New York dressed) birds, but only 1 of 24 frozen birds. Viable counts of up to 1.5 x 10(6)/chicken were obtained from fresh birds and 2.4 x 10(7)/chicken from uneviscerated birds. Surface swabbing of breasts, thighs, wings and vents of fresh chickens showed that contamination was generally distributed over the carcasses. Salmonellas were found in only 2 of 69 of the fresh chickens. The prevalence of several Lior and Penner C. jejuni serogroups was similar in chickens and sporadic human cases of enteritis. Penner serogroup 4 (mostly of Lior serogroup 1) was found in 26% of human isolates and 14% of chicken isolates. The rising incidence of campylobacter enteritis during the last 6 years could well be a reflection of the increasing proportion of fresh chickens consumed over that period (32% higher in 1986 than in 1981).
intangibleCanvas (2011)

With the advent of new sensing technologies, precision free-air interaction is becoming viable as a contender for the next generation of expressive, embodied interaction modalities. ZeroTouch [5], a novel multi-touch sensor that allows for free-air multi-finger, multi-object sensing, is one example of this next generation of free-air interfaces. We develop its use in a digitally-projected finger painting application, placing the see-through multitouch sensor in direct line-of-sight between an artist and a remote canvas. This allows the artist to reach through the sensor and paint on the intangibleCanvas as if it were directly in front of them. An iPad is employed as a multimodal workspace for color selection. We evaluate the system through an informal walk-up-and-play installation and comparative study, developing implications for interaction design using this type of precision free-air interface.

Coadministration of Ritonavir Strongly Enhances the Apparent Oral Bioavailability of Docetaxel in Patients with Solid Tumors (2009)

Coadministration of ritonavir significantly enhanced the apparent oral bioavailability of docetaxel. These data are promising and form the basis for further development of a clinically applicable oral formulation of docetaxel combined with ritonavir.
An Experimental Study on Pedestrian Classification (2006)

Detecting people in images is key for several important application domains in computer vision. This paper presents an in-depth experimental study on pedestrian classification; multiple feature-classifier combinations are examined with respect to their ROC performance and efficiency. We investigate global versus local and adaptive versus nonadaptive features, as exemplified by PCA coefficients, Haar wavelets, and local receptive fields (LRFs). In terms of classifiers, we consider the popular Support Vector Machines (SVMs), feed-forward neural networks, and k-nearest neighbor classifier. Experiments are performed on a large data set consisting of 4,000 pedestrian and more than 25,000 nonpedestrian (labeled) images captured in outdoor urban environments. Statistically meaningful results are obtained by analyzing performance variances caused by varying training and test sets. Furthermore, we investigate how classification performance and training sample size are correlated. Sample size is adjusted by increasing the number of manually labeled training data or by employing automatic bootstrapping or cascade techniques. Our experiments show that the novel combination of SVMs with LRF features performs best. A boosted cascade of Haar wavelets can, however, reach quite competitive results, at a fraction of computational cost. The data set used in this paper is made public, establishing a benchmark for this important problem.
Video interface for spatiotemporal interactions based on multi-dimensional video computing (2002)

Because digital video is becoming increasingly important for the networked multimedia society, the audio-visual access environment should allow us to do more than just passively watch. We propose a new video user interface concept made possible by multi-dimensional video computing. Multidimensional video computing offers a framework for analyzing a video, creating new structures, and restyling and visualizing the video according to the user's demands. The video interface visualizes video content and context structure comprehensibly to allow us to access the spatiotemporal information in videos intuitively. In this paper, we introduce our research activities toward a video interface based on the information extracted from the video. New video interfaces called VideoBrowser, PanoramaVideo, and VideoJigsaw are described.
ciRS-7 exonic sequence is embedded in a long non-coding RNA locus (2017)

ciRS-7 is an intensely studied, highly expressed and conserved circRNA. Essentially nothing is known about its biogenesis, including the location of its promoter. A prevailing assumption has been that ciRS-7 is an exceptional circRNA because it is transcribed from a locus lacking any mature linear RNA transcripts of the same sense. To study the biogenesis of ciRS-7, we developed an algorithm to define its promoter and predicted that the human ciRS-7 promoter coincides with that of the long non-coding RNA, LINC00632. We validated this prediction using multiple orthogonal experimental assays. We also used computational approaches and experimental validation to establish that ciRS-7 exonic sequence is embedded in linear transcripts that are flanked by cryptic exons in both human and mouse. Together, this experimental and computational evidence generates a new model for regulation of this locus: (a) ciRS-7 is like other circRNAs, as it is spliced into linear transcripts; (b) expression of ciRS-7 is primarily determined by the chromatin state of LINC00632 promoters; (c) transcription and splicing factors sufficient for ciRS-7 biogenesis are expressed in cells that lack detectable ciRS-7 expression. These findings have significant implications for the study of the regulation and function of ciRS-7, and the analytic framework we developed to jointly analyze RNA-seq and ChIP-seq data reveal the potential for genome-wide discovery of important biological regulation missed in current reference annotations.
Incorporation of <i>Chlorella vulgaris</i> and <i>Spirulina maxima</i> biomass in pasta products. Part 1: Preparation and evaluation (2010)

Microalgae pastas presented very appellative colours, such as orange and green, similar to pastas produced with vegetables, with nutritional advantages, showing energetic values similar to commercial pastas. The use of microalgae biomass can enhance the nutritional and sensorial quality of pasta, without affecting its cooking and textural properties.
They are who they say they are (1994)

Despite limited knowledge, most parents had decided to vaccinate their daughter(s). Given evidence of diminished access to information among Black and Hispanic parents, programs should focus on reaching these groups. Interventions should address parental concerns about behavioral consequences, reduce structural barriers, and promote the perception that vaccination is endorsed by significant others. Moreover, interventions may need to address mistrust of pharmaceutical companies. IMPACT STATEMENT: This study documents factors associated with parental decisions about HPV vaccination for their daughter(s) and provides direction for intervention development.
Bayesian Hypernetworks (2017)

We study Bayesian hypernetworks: a framework for approximate Bayesian inference in neural networks. A Bayesian hypernetwork $\h$ is a neural network which learns to transform a simple noise distribution, $p(\vecε) = \N(\vec 0,\mat I)$, to a distribution $q(\pp) := q(h(\vecε))$ over the parameters $\pp$ of another neural network (the "primary network")\@. We train $q$ with variational inference, using an invertible $\h$ to enable efficient estimation of the variational lower bound on the posterior $p(\pp | \D)$ via sampling. In contrast to most methods for Bayesian deep learning, Bayesian hypernets can represent a complex multimodal approximate posterior with correlations between parameters, while enabling cheap iid sampling of~$q(\pp)$. In practice, Bayesian hypernets can provide a better defense against adversarial examples than dropout, and also exhibit competitive performance on a suite of tasks which evaluate model uncertainty, including regularization, active learning, and anomaly detection.
Design and performance of VQ-based hybrid digital-analog joint source-channel codes (2002)

A joint source-channel hybrid digital-analog (HDA) vector quantization (VQ) system is presented. The main advantage of the new VQ-based HDA system is that it achieves excellent rate-distortion-capacity performance at the design signal-to-noise ratio (SNR) while maintaining a "graceful improvement" characteristic at higher SNRs. It is demonstrated that, within the HDA framework, the parameters of the system can be optimized using an iterative procedure similar to that of channel-optimized vector quantizer design. Comparisons are made with three purely digital systems and one purely analog system. It is found that, at high SNRs, the VQ-based HDA system is superior to the other investigated systems. At low SNRs, the performance of the new scheme can be improved using the optimization procedure and using soft decoding in the digital part of the system. These results demonstrate that the introduced scheme provides an attractive method for terrestrial broadcasting applications.
Exploring Ultimate Water Capillary Evaporation in Nanoscale Conduits (2017)

Capillary evaporation in nanoscale conduits is an efficient heat/mass transfer strategy that has been widely utilized by both nature and mankind. Despite its broad impact, the ultimate transport limits of capillary evaporation in nanoscale conduits, governed by the evaporation/condensation kinetics at the liquid-vapor interface, have remained poorly understood. Here we report experimental study of the kinetic limits of water capillary evaporation in two dimensional nanochannels using a novel hybrid channel design. Our results show that the kinetic-limited evaporation fluxes break down the limits predicated by the classical Hertz-Knudsen equation by an order of magnitude, reaching values up to 37.5 mm/s with corresponding heat fluxes up to 8500 W/cm<sup>2</sup>. The measured evaporation flux increases with decreasing channel height and relative humidity but decreases as the channel temperature decreases. Our findings have implications for further understanding evaporation at the nanoscale and developing capillary evaporation-based technologies for both energy- and bio-related applications.
Conditional transactions: a model of computation for active databases (2002)

A transaction model for active databases is introduced. Concurrent execution of rules needs to be carefully managed to ensure consistent semantics. It is shown that serializability is not always sufficient for correctness. A new criterion, conditional conflict serializability (CCS) is developed and shown to ensure the desired correctness. A graph-based scheduler for it is presented. Practical schedulers should also be recoverable, which the graph-based scheduler is not. The authors prove that conventional two-phase locking also achieves CCS, and can thus be used in practice.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Yeast: An Experimental Organism for 21st Century Biology (2011)

In this essay, we revisit the status of yeast as a model system for biology. We first summarize important contributions of yeast to eukaryotic biology that we anticipated in 1988 in our first article on the subject. We then describe transformative developments that we did not anticipate, most of which followed the publication of the complete genomic sequence of Saccharomyces cerevisiae in 1996. In the intervening 23 years it appears to us that yeast has graduated from a position as the premier model for eukaryotic cell biology to become the pioneer organism that has facilitated the establishment of the entirely new fields of study called "functional genomics" and "systems biology." These new fields look beyond the functions of individual genes and proteins, focusing on how these interact and work together to determine the properties of living cells and organisms.
Synthesis of Various Water-Soluble G<sub>60</sub>Derivatives and Their Superoxide-Quenching Activity (2000)

Abstract In order to examine the utility of fullerene as a medicinal application, we evaluated the reaction between fullerene derivatives and active oxygen species in vitro. This paper describes the synthesis of various water-soluble C60 derivatives (cationic and anionic) and evaluation of their superoxide (O2 −) quenching activity. Cationic C60 derivatives showed fairly high efficiency.
E-cadherin mediated adhesion system in cancer cells (1996)

Numerous studies have suggested that the E-cadherin adhesion system is disturbed in cancer cells through various mechanisms and these impaired functions of E-cadherin contribute to the release of cancer cells from the primary lesion and to cell dedifferentiation.
Modulation of NMDA receptor function: implications for vertebrate neural development (1994)

The NMDA subtype of glutamate receptor is hypothesized to mediate synaptic competition in the developing brain by stabilizing converging synapses that have correlated activity patterns. Disruption of NMDA receptor function during development interferes with synapse elimination and sensory map formation. Moreover, many studies indicate that NMDA receptor function is high during times of synaptic rearrangement. In this review, a corollary of the NMDA receptor hypothesis for activity-dependent synapse stabilization is proposed. As developing inputs increase in number and strength, the increasing excitatory synaptic activity in young neurons should lead to increases in postsynaptic Ca2+ influx through NMDA receptors. This Ca2+ flux is postulated to trigger a feedback system that changes the subunit composition of the NMDA receptor complex so that less Ca2+ enters postsynaptic cells upon NMDA receptor activation. Changes in NMDA receptor effectiveness resulting from manipulations of activity are consistent with the idea that NMDA receptor function is under the control of activity. This postulate of activity-dependent control of NMDA receptor expression has implications for the control of brain plasticity. If particular combinations of NMDA receptor subunits typically expressed in young animals are better than adult receptor types at maintaining synapses in regions where they are not well correlated with other inputs, then expression of these juvenile subunit combinations could facilitate synaptic rearrangements in the mature brain after the normal end of synaptic plasticity. Thus, understanding the regulation of NMDA receptor function during development could provide a novel approach to restructuring circuitry in the adult brain to compensate for damage produced by trauma or disease.
雙重邊緣化：東莞手工腐竹的日常實作與官民「非遺化」治理 (2019)

本研究考察東莞新村手工腐竹的日常變遷與當代困境，藉此呈現相對弱勢的傳統技藝文化、現代化生產與都市文化治理策略之間的糾葛纏繞。本文意圖理解腐竹技藝作爲日常傳統與作爲「非遺」兩者，經由不同行動者力量所牽扯並顯露的張力和弔詭，以及在這種情況下的延續可能。透過腐竹和技藝人的際遇，作者揭露「非遺」的治理策略在選擇性保存和發展之餘，如何形塑和再造着傳統的邊緣處境。
 作者以田野參與式觀察及深度訪談爲主要研究方法，首先呈現東莞腐竹及其製作技藝如何由盛轉衰的發展脈絡和歷史轉折。然後作者將細述新村的不同手工腐竹技藝人的日常實作，瞭解其邊緣處境和因應之道，揭開勞動中顯現的異化與傳承問題，及伴隨「非遺化」而來的轉機和競奪。最後，本文把視野轉向作爲文化治理策略的東莞「非遺」，探討實作中的公部門、文化仲介者工作者和技藝人，他們所面臨的曖昧複雜情境，以進一步凸顯腐竹技藝在「低端非遺化」過程中的斷層和缺席狀態。
 原義爲保護和傳承傳統的「非遺化」實踐，在新村腐竹的案例中，成了一個把邊緣的傳統先擡高爲「非遺」，再納入／推入另一層邊緣的過程。作者力圖呈現其中的弔詭和困境：一、創新跨界的壟斷租金追求，與獨特性、真實性保存之間的矛盾，使得腐竹技藝在官方「非遺」實踐中無計可施，位居邊緣；二、形塑出一批外在於「非遺」的文化工作者和專家，並在其中佔據發展和論述的核心，逐步削弱、排擠和邊緣化着再生產文化的腐竹技藝人；三、「非遺」的運作邏輯與等級分化機制，使得最後納入「非遺」的傳統（技藝人），並不能與真正需要保護和傳承的傳統（技藝人）畫上等號，後者反而可能會被排除於制度和保護之外。
 東莞新村腐竹的故事提供了「非遺」傳統的另一個敘述版本，有助於我們反思作爲文化治理手段的大規模「非遺」建設的保護成效，以及襲產研究中常遭忽略的邊緣傳統，其被擠壓的生存現實與超越邊緣的應對可能。
Reductive deoxygenation by Cp2ZrHCl: Selective formation of imines via zirconation/hydrozirconation of amides (1993)

A general new process is described by which zirconium (IV) salts of secondary amides and lactams are transformed by Cp2ZrHCl directly into N-substituted imines in one step.
Assays for Kinesin Microtubule-Stimulated AT Pase Activity (2001)

Methods for assay of ATPase rates can be classified into broad categories depending on whether an ATP-regenerating system or a continuous coupled assay is employed versus quenching at discrete times for subsequent analysis for production of Pi or ADP (or, more rarely, for the loss of ATP).
