An emulation-based real-time power profiling unit for embedded software (2009)

The power consumption of battery-powered and energy-scavenging devices has become a major design metric for embedded systems. Increasingly complex software applications as well as rising demands in operating times while having restricted power budgets make power-aware system design indispensable. In this paper we present an emulation-based power profiling approach allowing for real-time power analysis of embedded systems. Power saving potential as well as power-critical events can be identified in much less time compared to power simulations. Hence, the designer can take countermeasures already in early design stages, which enhances development efficiency and decreases time-to-market. Accuracies achieved for a deep submicron smart-card controller are greater than 90% compared to gate-level simulations.
Information Structuring and Product Classification (2006)

Today’s e-commerce often suffers from problems of differing terminologies used by vendors and buyers. Using standardized product classification schemes, such as UNSPSC or eCl@ss often requires time-consuming and costly manual “translation” of internal product catalogues into the standardized terminologies. This paper explores the use of text mining and machine learning approaches to the task of automatic product classification. The results obtained on a real-life product catalogue indicate that high accuracy can be reached, but that some instances cannot be classified automatically, thus suggesting semi-automatic and interactive procedures.
Fronts in a bistable medium with two global constraints: Oscillatory instability and large-amplitude limit-cycle motion (1998)

We study the propagation of fronts in a reaction-diffusion model of a bistable medium with two global constraints. The model applies to lateral current density fronts in three-electrode bistable semiconductor systems driven by the main and gate circuits. When taken separately, these constraints provide positive and negative feedbacks on front dynamics leading to accelerated and decelerated fronts, respectively. Under two constraints, there is an interplay between positive and negative feedback resulting in an oscillatory instability of a stationary front and large-amplitude limit-cycle motion. The instability occurs purely due to the global coupling and is not sensitive to the effect of the boundaries.
Fluid Sensing Using Quartz Tuning Forks—Measurement Technology and Applications (2019)

We provide an overview of recent achievements using quartz tuning forks for sensing liquid viscosity and density. The benefits of using quartz crystal tuning forks (QTFs) over other sensors are discussed on the basis of physical arguments and issues arising in real world applications. The path to highly accurate and robust measurement systems is described and a recently devised system considering these findings is presented. The performance of the system is analyzed for applications such as the mixing ratio measurement of fuels, diesel-soot contamination for engine oil condition monitoring, and particle size characterization in suspensions. It is concluded that using properly designed systems enables a variety of applications in industry and research.
The relevance of pH to gingivitis and periodontitis. (2001)

Although the resting pH of the oral cavity is between 5 and 9, it is also known to vary widely depending on a number of factors. While this phenomenon has been extensively studied in relation to dental caries, little research has been undertaken of its possible significance in relation to gingivitis and periodontitis. This study aimed to investigate any possible correlations between pH and gingivitis and periodontal pocketing. Forty-two subjects with gingivitis and periodontitis were included in this study. Strips of pH indicator paper were placed on the floor of the mouth, soft palate, healthy gingival margins, sites of superficial gingivitis, and in periodontal pockets. It was shown that pH varies in different sites in the mouth. Statistically significant correlations between pH and gingivitis were not identified, but significant correlations between pH and periodontal pocketing were evident, although wide variations were observed between pockets. Randomly distributed pH readings ranging from 2-9 were observed within a single periodontal pocket. This implies that the physiology of processes taking place within periodontal pockets is wide ranging and complex. Different levels of pH indicate different chemical environments which may imply that different disease and reparative processes are occurring simultaneously within each periodontal pocket. The limitations of the assessment technique used in this study were highlighted and compared in relation to results obtained from other studies using more sophisticated techniques and it was found that the results obtained using this unsophisticated technique were in agreement with most of these other studies. Therefore, this technique may have applications in screening for disease activity in clinical practice. However, the need for further work to confirm the observations of this study is necessary to corroborate these associations.
Active site residues in m‐calpain: identification by site‐directed mutagenesis (1995)

Site-directed mutagenesis was used to alter putative active site residues in the large subunit of calpain, and the activity of the mutants was measured following coexpression in E. coli of both calpain subunits and purification of the resultant dimers. Mutants Cys105Ser, His262Ala and Asn286Ala had no activity. Together with sequence comparisons among cysteine proteinases, the results suggest that these residues constitute the catalytic triad in calpain. Mutants Asn286Asp and Trp288Tyr had low activity, consistent with interaction of these residues with His262.
Biometric Transaction Authentication using Smartphones (2018)

Secure and robust authentication of users and customers is critical, as an increasing number of services from banks, health and government sectors are made available to people as online services. Recent development in the area of biometrics, e.g. biometric systems in smartphones, has contributed to higher adoption of the technology as a viable authentication factor in modern systems. In this work, we propose an approach for authenticating transactions in an online bank by using a combination of Bloom filters and error correcting codes. Firstly, protected biometric templates, using Bloom filters, are generated from faces detected in images captured using smartphones. Secondly, a key, shared between a smartphone and a bank server, is encoded using error correcting codes. The encoded key is then secured in the smartphone using the protected biometric templates. Authentication of a banking transaction is realised by unlocking the secured key with a protected biometric template that is close to the template used to lock the key. Experiments are performed on a database consisting of images and videos captured using an iPhone 6S.

A novel sequence-specific RNA quantification method using nicking endonuclease, dual-labeled fluorescent DNA probe, and conformation-interchangeable oligo-DNA (2008)

We have developed a novel, single-step, isothermal, signal-amplified, and sequence-specific RNA quantification method (L-assay). The L-assay consists of nicking endonuclease, a dual-labeled fluorescent DNA probe (DL-probe), and conformation-interchangeable oligo-DNA (L-DNA). This signal-amplified assay can quantify target RNA concentration in a sequence-specific manner with a coefficient of variation (Cv) of 5% and a lower limit of detection of 0.1 nM. Moreover, this assay allows quantification of target RNA even in the presence of a several thousandfold excess by weight of cellular RNA. In addition, this assay can be used to measure the changes in RNA concentration in real-time and to quantify short RNAs (<30 nucleotides). The L-assay requires only incubation under isothermal conditions, is inexpensive, and is expected to be useful for basic research requiring high-accuracy, easy-to-use RNA quantification, and real-time quantification.
Attention and automation: New perspectives on mental underload and performance (2002)

There is considerable evidence in the ergonomics literature that automation can significantly reduce operator mental workload. Furthermore, reducing mental workload is not necessarily a good thing, particularly in cases where the level is already manageable. This raises the issue of mental underload, which can be at least as detrimental to performance as overload. However, although it is widely recognized that mental underload is detrimental to performance, there are very few attempts to explain why this may be the case. <br/><br/>It is argued in this paper that, until the need for a human operator is completely eliminated, automation has psychological implications relevant in both theoretical and applied domains. The present paper reviews theories of attention, as well as the literature on mental workload and automation, to synthesize a new explanation for the effects of mental underload on performance. Malleable attentional resources theory proposes that attentional capacity shrinks to accommodate reductions in mental workload, and that this shrinkage is responsible for the underload effect. The theory is discussed with respect to the applied implications for ergonomics research.
Microscopic localization of active proteases by in situ zymography: detection of matrix metalloproteinase activity in vascular tissue (1995)

Many physiological and pathological processes involve tissue remodeling due in part to degradation of extracellular matrix. Several factors limit current approaches used for detection of matrix-degrading enzymes in tissues. Matrix metalloproteinases (MMPs), enzymes specialized in catabolism of extracellular matrix constituents, require processing from inactive zymogen precursors to gain enzymatic function. Presently available antibodies do not distinguish between precursor and proteolytically processed forms of MMPs. Also, ubiquitous tissue inhibitors of metalloproteinases (TIMPs) could prevent matrix degradation by MMPs even if the enzymes were in an active form. For these reasons immunocytochemistry does not provide information regarding the functional state of these enzymes. Biochemical studies of tissue extracts preclude localization and entail the possibility of artifactual activation of the enzymes consequent to tissue disruption. To obviate these problems, we have adapted substrate zymography to frozen tissue sections to assess net proteolytic activity in situ. We report here the details and the validation of this methodology. Initial experiments defined casein fluorescently labeled with resorufin as a useful substrate for detecting stromelysin, and fluoresceinated gelatin or autoradiographic emulsion as suitable for detecting gelatinolytic activity by this approach. Either TIMP-1 or the Zn chelator 1,10-phenanthroline reduced the zymographic activity in cryosections of atheroma from humans or rabbits. Inhibitors of serine proteases did not reduce the extent of substrate lysis substantially. In situ zymography preserves the fine morphological details of the tissue and can complement the study of enzyme expression by other microscopic techniques, such as immunocytochemistry. This approach may prove generally applicable for the detection of protease activity in tissue sections permitting exploration of the roles of these enzymes in pathobiology.
Position Estimation of a Matrix-Converter-Fed AC PM Machine From Zero to High Speed Using PWM Excitation (2009)

This paper describes a sensorless position estimation method for a permanent-magnet (PM) motor fed from a three-phase matrix converter using only its space-vector pulsewidth-modulation (SVPWM) sequence. The scheme employs measurements of <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">di</i> i/ <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dt</i> of the motor line currents to construct orthogonal ldquoresolverlikerdquo position signals. In principle, the SVPWM waveforms provide sufficient excitation to extract the position signal from the motor current. However, in order to improve the signal-to-noise ratio of the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">di</i> / <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dt</i> signals, a small modification to the SVPWM is required. Sensorless control of the PM synchronous motor at zero and high speeds is demonstrated experimentally. The use of alternative input voltage vectors is also investigated to reduce the current ripple.
러시아 극동,자바이칼지역 개발 프로그램과 동북아 지역협력 (2012)

본 논문의 목적은 최근 러시아의 극동지역의 개발 전략과 프로그램을 검토하고, 극동지역 개발의 가능성과 제약, 그리고 이 프로그램을 동북아의 지역협력의 발전과 긴밀하게 연계하여 실현하기 위한 조건을 분석하는 것이다. 최근러시아는 「극동·자바이칼 개발 프로그램 2013」, 「극동개발전략 2025」등을 통해 극동·자바이칼 지역의 경제잠재력의 증대, 아·태지역에서 러시아의 국가이익 실현, 안락한 거주환경 구축 및 정주 강화 등을 지향하는 종합적인 지역개발을 추진하고 있다. 그렇지만 에너지와 교통 등의 분야에서 극동지역의 개발과 동북아 지역협력이 상호 연계 발전될 수 있는 큰 잠재력을 갖고 있음에도 불구하고, 러시아의 재원부족 등 개발 프로그램의 한계, 그리고 동북아 지역주의에 내재된 국가 간 협력과 경쟁의 이중주의 때문에 지금까지의 결과는 매우 실망스러운 상황이다. 향후 한국을 비롯한 역내 국가들은 역내 경제통합과 지속적인 경제성장을 담보하기 위해 극동지역의 개발 잠재력을 활용하는 적극적인 투자진출을 모색해야 하며, 상호신뢰를 전제로 전략적 이익 공유지점을 실질협력 사업으로 전환하며, 양자·다자 지역협력을 위한 제도적 토대를 구축하는 것이 필요하다.
Analysis and valuation of the health and climate change cobenefits of dietary change (2016)

What we eat greatly influences our personal health and the environment we all share. Recent analyses have highlighted the likely dual health and environmental benefits of reducing the fraction of animal-sourced foods in our diets. Here, we couple for the first time, to our knowledge, a region-specific global health model based on dietary and weight-related risk factors with emissions accounting and economic valuation modules to quantify the linked health and environmental consequences of dietary changes. We find that the impacts of dietary changes toward less meat and more plant-based diets vary greatly among regions. The largest absolute environmental and health benefits result from diet shifts in developing countries whereas Western high-income and middle-income countries gain most in per capita terms. Transitioning toward more plant-based diets that are in line with standard dietary guidelines could reduce global mortality by 6-10% and food-related greenhouse gas emissions by 29-70% compared with a reference scenario in 2050. We find that the monetized value of the improvements in health would be comparable with, or exceed, the value of the environmental benefits although the exact valuation method used considerably affects the estimated amounts. Overall, we estimate the economic benefits of improving diets to be 1-31 trillion US dollars, which is equivalent to 0.4-13% of global gross domestic product (GDP) in 2050. However, significant changes in the global food system would be necessary for regional diets to match the dietary patterns studied here.
Tryptophan Fluorescence Reports Nucleotide-induced Conformational Changes in a Domain of the ArsA ATPase (1997)

The ars operon of plasmid R773 encodes an ATP-dependent extrusion pump for arsenite and antimonite in Escherichia coli. The ArsA ATPase is the catalytic subunit of the pump protein, with two nucleotide binding consensus sequences, one in the NH2-terminal half and one in the COOH-terminal half of the protein. A 12-residue consensus sequence (DTAPTGHTIRLL) has been identified in ArsA homologs from eubacteria, archebacteria, fungi, plants, and animals. ArsA enzymes were constructed containing single tryptophan residues at either end of this conserved sequence. The emission spectrum of the fluorescence of the tryptophan on the COOH-terminal end (Trp-159) indicated a relatively hydrophilic environment for this residue. An increase in intrinsic tryptophan fluorescence and a blue shift of the maximum emission wavelength were observed upon addition of MgATP, indicating movement of Trp-159 into a relatively less polar environment. No fluorescence response was observed with MgADP, with nonhydrolyzable ATP analogs, or with MgATP by catalytically inactive enyzmes. This suggests that the location Trp-159 is shifted only during hydrolysis of ATP. In contrast, the emission spectrum of Trp-141, located on the NH2-terminal side of the consensus sequence, indicated a relatively nonpolar environment. The maximum emission wavelength red shifted upon addition of MgADP. MgATP slowly produced a response that correlated with product formation, suggesting that the environment of Trp-141 is sensitive only to MgADP binding. Thus, during ATP hydrolysis the COOH-terminal end of the conserved domain moves into a less polar environment, whereas the NH2-terminal end moves into a more hydrophilic environment as product is formed. A hypothesis is presented in which the conserved domain of ArsA and homologs is an energy transduction domain involved in transmission of the energy of ATP hydrolysis to biological functions such as transport.
Direct Optical Detection of Aptamer Conformational Changes Induced by Target Molecules (2009)

Aptamers are single-stranded DNA/RNA oligomers that fold into three-dimensional conformations in the presence of specific molecular targets. Surface-enhanced Raman spectroscopy (SERS) of thiol-bound DNA aptamer self-assembled monolayers on Au nanoshell surfaces provides a direct, label-free detection method for the interaction of DNA aptamers with target molecules. A spectral cross-correlation function, Gamma, is shown to be a useful metric to quantify complex changes in the SERS spectra resulting from conformational changes in the aptamer induced by target analytes. While the pristine, unexposed anti-PDGF (PDGF = platelet-derived growth factor) aptamer yields highly reproducible spectra with Gamma = 0.91 +/- 0.01, following incubation with PDGF, the reproducibility of the SERS spectra is dramatically reduced, yielding Gamma = 0.67 +/- 0.02. This approach also allows us to discriminate the response of a cocaine aptamer to its target from its weaker response to nonspecific analyte molecules.
Paclitaxel 175 or 225 mg per Meters Squared With Carboplatin in Advanced Ovarian Cancer: A Randomized Trial (2004)

This randomized trial suggests that paclitaxel 175 mg/m(2) plus carboplatin AUC6 is the schedule with a more favorable profile than paclitaxel 225 mg/m(2) plus carboplatin AUC6.
An Improved Parallel Access Technology on Routing Table for Threaded BGP (2009)

The stringent requirement for the high efficiency of routing protocol on Internet will be satisfied by exploiting the threaded border gateway protocol (TBGP) on multi-cores. Since the TBGP performance is restricted by a mass of contentions when racing to access the routing table, a highly-efficient parallel access approach is originally proposed to achieve the ultra-high route processing speed. In this paper, a novel routing table structure consisting of two-level tries is presented for fast parallel access, and a heuristic-based divide-and-recombine algorithm is devised to balance the table accesses and release the contentions, thereby accelerating the parallel route update of multi-threading. By modifying the typical table operations such as lookup, insert, etc., the correctness of two-level tries table is validated according to the operation behaviors of traditional routing table. Experimental results on dual quad-core Xeon server show that the parallel access contentions decrease sharply by 92.5% versus traditional routing table, and the maximal update time per thread is obviously reduced by 56.8% on average with little overhead. Then, the throughput of BGP update message is measured to be improved by about 169%, delivering significant performance improvement of BGP.

Feature guided automated collaborative filtering (1995)

Information filtering systems have traditionally relied on some form of content analysis of documents to represent a profile of user interests. Such content filtering is generally ineffective in domains with diverse media types such as audio, video, and images, because machineanalysis of such media is hard. Recently, information filtering systems relying primarily on human evaluations of documents have been built. Such automated collaborative filtering systems work by discovering correlations in evaluations of documents amongst users, and by using these correlations to recommend new documents. However, such systems rely on the implicit assumption that all the features of a document are equally important to a user&apos;s evaluation of that document. This assumption breaks down in broad domains, (such as all documents in the World Wide Web), where users correlate well only for some features of a document they evaluated similarly. This thesis claims that using a combination of easily extractib...
