Declarative updates of relational databases (1995)

This article presents a declarative language, called update calculus , of relational database updates. A formula in update calculus involves conditions for the current database, as well as assertions about a new database. Logical connectives and quantifiers become constructors of complex updates, offering flexible specifications of database transformations. Update calculus can express all nondeterministic database transformations that are polynomial time. For set-at-a-time evaluation of updates, we present a corresponding update algebra . Existing techniques of query processing can be incorporated into update evaluation. We show that updates in update calculus can be translated into expressions in update algebra and vice versa.
EEG processing by the Cerebral Function Monitor (CFM). (1979)

The Cerebral Function Monitor (CFM) is a machine designed to monitor EEG over long periods of time from hours to several days. It produces on a slow speed chart recorder a write-out of a processed EEG signal in parallel with a continuous measurement of electrode impedance. A description is given of the way in which the CFM processes both EEG and electrode impedance information. Some CFM applications are mentioned.
Hybrid wireless-optical broadband access network(woban) : prototype development and research challenges (2009)

The hybrid wireless-optical broadband access network is emerging as a promising technology to provide economical and scalable broadband Internet access. In this cross-domain network architecture, end users receive broadband services through a wireless, mesh front end that is connected to the optical backhaul through gateway nodes. In this article, we present the architecture and functional characteristics of a WOBAN prototype built in the Networks Lab at UC Davis. We discuss research challenges for hybrid networks based on our experimental observations.
Research on Augmented Reality Extended Tracking Technology for Mobile Terminal (2018)

In consideration of problems with mobile terminal augmented reality, including instability and robustness of the spatial registration results, in this paper, we proposed an improved extended tracking algorithm based on mobile terminal. The algorithm adjusts the recursion of the decision trees based on the feature points, which overcomes the problems of inadequate feature tracking and weak stability of the traditional tracking algorithms. After matching and tracking the feature points of the image, the algorithm of this paper combines the assistant tracking technology of mobile multi-sensor fusion, and realizes the augmented reality system. The experimental results show that the system improves the display effect of the virtual objects in the real scene when there are light, scale and noise in the scene for the complicated outdoor environment, and has strong robustness and stability.
Intrusion Protection against SQL Injection Attacks Using a Reverse Proxy (2012)

In this era where Internet has captured the world, level of security that this Internet provides has not grown as fast as the Internet application. Internet has eased the life of human in numerous ways, but the drawbacks like the intrusions that are attached with the Internet applications sustains the growth of these applications. One such intrusion is the SQL Injection attacks (SQLIA). Since SQLIA contributes 25% of the total Internet attacks, much research is being carried out in this area. In this paper we propose a method to detect the SQL injection. We use a Reverse proxy and MD5 algorithm to check out SQL injection in user input. Using grammar expressions rules we check for SQL injection in URL's. This system has been tested on standard test bed applications and our work has shown significant improvement detecting and curbing the SQLIA.
Investigation of molecular and chiroptical characteristics of optically active functional vinyl copolymers possessing main‐chain chirality (1992)

Abstract Optically active styrene‐methyl methacrylate and styrene‐methacrylonitrile copolymers were obtained by template assisted asymmetric copolymerization of 3,4‐cyclohexyhdene‐D‐mannitol‐1,2;5,6‐bis‐O[(4‐vinylphenyl)boronate] ( 1 ) with the corresponding comonomers followed by removal of the template and deboronation. By polymer analog modification methods, several optically active functional copolymers were obtained starting with these copolymers. The resulting polymers were subjected to different types of spectroscopic analysis. Thus, the results obtained from IR, 13 C‐NMR and GPC were of great value for detailed structural analysis of these polymers providing both qualitative and quantitative informations in terms of mode and neatness of substitution and degree of functionalization. The chiroptical measurement results obtained from circular dichroic (CD) studies have been utilized to analyze precisely the substituent dependent local solution stereochemistry of these chiral polymers. © 1992 John Wiley & Sons, Inc.
Effect of neutering on two groups of feral cats (1984)

Two colonies of urban feral cats were subjected to a programme of population control by trapping, neutering and returning to site. The behaviour of individual cats and the stability of the groups was studied before and after the programme, which was then assessed in terms of its humaneness and effectiveness as a means of control. The method was satisfactory on both counts and may be recommended for controlling feral cat colonies where the welfare of the cats can be assured after their return.
Selective Deposition of Ru Nanoparticles on TiSi<sub>2</sub> Nanonet and Its Utilization for Li<sub>2</sub>O<sub>2</sub> Formation and Decomposition (2014)

The Li-O2 battery promises high capacity to meet the need for electrochemical energy storage applications. Successful development of the technology hinges on the availability of stable cathodes. The reactivity exhibited by a carbon support compromises the cyclability of Li-O2 operation. A noncarbon cathode support has therefore become a necessity. Using a TiSi2 nanonet as a high surface area, conductive support, we obtained a new noncarbon cathode material that corrects the deficiency. To enable oxygen reduction and evolution, Ru nanoparticles were deposited by atomic layer deposition onto TiSi2 nanonets. A surprising site-selective growth whereupon Ru nanoparticles only deposit onto the b planes of TiSi2 was observed. DFT calculations show that the selectivity is a result of different interface energetics. The resulting heteronanostructure proves to be a highly effective cathode material. It enables Li-O2 test cells that can be recharged more than 100 cycles with average round-trip efficiencies >70%.
Phase Current Sensor and Short-Circuit Detection based on Rogowski Coils Integrated on Gate Driver for 1.2 kV SiC MOSFET Half-Bridge Module (2018)

Silicon-carbide (SiC) MOSFETs are enabling electrical vehicle motor drives to meet the demands of higher power density, efficiency, and lower system cost. Hence, this paper seeks to explore the benefits that a gate-driver-level intelligence can contribute to SiC-based power inverters. The intelligence is brought by PCB-embedded Rogowski switch-current sensors (RSCS) integrated on the gate driver of a 1.2 kV, 300 A SiC MOSFET half-bridge module. They collect two MOSFET switch currents in a manner of high magnitude, high bandwidth, and solid signal isolation. The switch-current signals are used for short-circuit detection under various fault impedances, as well as for phase-current reconstruction by subtracting one switch current from another. The fundamentals and noise-immunity design of the gate driver containing the RSCS are presented in the paper and can be applied to any half-bridge power module. A three-phase inverter prototype has been built and operated in continuous PWM mode. On this setup, the performance and limitations of the short-circuit detection and phase-current reconstruction are experimentally validated by comparing with commercial current probes and Hall sensors.
GaN Bulk Substrates for GaN Based LEDs and LDs (2000)

In the present work, we discuss the importance of bulk GaN substrates for GaN based LEDs and LDs. As crystal growth methods for growing bulk GaN, we study the hydride vapor phase epitaxial (HVPE) method and the pressure-controlled solution growth (PC-SG) method. The recent results obtained by these two methods are presented. The maximum size of the grown single crystals was 3 × 4 cm2 for the HVPE method and 12 mm diameter for the PC-SG method. Both methods can provide high quality GaN substrates, with a low dislocation density of the level of less than 106 cm–2.
BlobSeer: Towards efficient data storage management for large-scale, distributed systems (2010)

With data volumes increasing at a high rate and the emergence of highly scalable infrastructures (cloud computing, petascale computing), distributed management of data becomes a crucial issue that faces many challenges. This thesis brings several contributions in order to address such challenges. First, it proposes a set of principles for designing highly scalable distributed storage systems that are optimized for heavy data access concurrency. In particular, it highlights the potentially large benefits of using versioning in this context. Second, based on these principles, it introduces a series of distributed data and metadata management algorithms that enable a high throughput under concurrency. Third, it shows how to efficiently implement these algorithms in practice, dealing with key issues such as high-performance parallel transfers, efficient maintainance of distributed data structures, fault tolerance, etc. These results are used to build BlobSeer, an experimental prototype that is used to demonstrate both the theoretical benefits of the approach in synthetic benchmarks, as well as the practical benefits in real-life, applicative scenarios: as a storage backend for MapReduce applications, as a storage backend for deployment and snapshotting of virtual machine images in clouds, as a quality-of-service enabled data storage service for cloud applications. Extensive experimentations on the Grid'5000 testbed show that BlobSeer remains scalable and sustains a high throughput even under heavy access concurrency, outperforming by a large margin several state-of-art approaches.

Pharmacokinetic Profile of the Oral Direct Thrombin Inhibitor Dabigatran Etexilate in Healthy Volunteers and Patients Undergoing Total Hip Replacement (2005)

Dabigatran etexilate is an oral low-molecular-weight direct thrombin inhibitor. Following oral administration, dabigatran etexilate is rapidly converted to its active form, dabigatran. The authors investigated the absorption, distribution, and elimination of a single 150-mg dose capsule formulation of dabigatran etexilate in healthy volunteers and patients undergoing total hip replacement. In an open-label, 3-way crossover study, dabigatran etexilate was administered to 18 male volunteers in the fasted state, after administration of food and with coadministration of the proton pump inhibitor, pantoprazole. In a subsequent multicenter, open-label study, 59 patients received a single dose of dabigatran etexilate, administered 1 to 3 hours following total hip replacement. In healthy volunteers, food had no effect on the extent of absorption of dabigatran etexilate, although there was reduced interindividual variability for dabigatran maximum plasma concentration and AUC(0-infinity). A decrease in the mean dabigatran AUC(0-infinity) (904 to 705 ng*h/mL) occurred with coadministration of pantoprazole. In patients undergoing total hip replacement, immediate onset of absorption was seen with the maximum plasma concentration of dabigatran occurring after 6 hours. The AUC(0-24) of dabigatran was 88% of the steady-state AUC using a preliminary tablet formulation and 106% of that seen in the healthy volunteer study. Compared with healthy volunteers, the postoperative profile was flattened with delayed peak concentrations. In summary, administration of the dabigatran etexilate capsule with food has no effect on the extent of dabigatran absorption, with a moderate decrease when coadministered with pantoprazole. Adequate plasma concentrations of dabigatran were seen with early postoperative administration of the dabigatran etexilate capsule. These pharmacokinetic characteristics confirm the suitability of this oral solid dosage form for use in future clinical trials.
Spectrophotometric assay for urinary N-acetyl-beta-D-glucosaminidase activity. (1981)

An improved assay for N-acetyl-beta-D-glucosaminidase activity in urine is described that involves (a) gel filtration to separate the enzyme from inhibitors in urine, (b) enzymic hydrolysis of p-nitrophenyl-N-acetyl-beta-D-glucosaminide at pH 4.4, and (c) spectrophotometry of the liberated p-nitrophenylate. Measurements of activity of the enzyme in 58 urine specimens correlated closely (r = 0.9998) with results by an established procedure. The within-run coefficient of variation (CV) was 3.7%; the between-run CV averaged 6.8%. Reference values for the activity were established by assays of urine specimens from 135 healthy persons, age two weeks to 52 years. Efficacy of the assay for detection of nephrotoxicity was demonstrated in rats after experimental induction of reversible renal insufficiency by intraperitoneal injection of nickel chloride. Clinical application of the assay in approximately 1000 patients corroborated its utility for detection and monitoring of renal disorders.
Text-independent pronunciation evaluation based on phone-level Gaussian classifier (2010)

This paper presents a novel text-independent pronunciation evaluation method. The method aims at testing the mandarin Putonghua pronunciation proficiency of the dialectal speakers from every area of China. In the proposed method, 5 pronunciation proficiency levels are assigned for each phone; accordingly, 5 Single Gaussian classifiers are created to represent the 5 levels for a phone. 4 phone-level features are described and used in the classifiers. In the testing step, phone-level output probabilities are combined to get the sentence-level likelihood.
Does wearing clothing made of a synthetic “cooling” fabric improve indoor cycle exercise endurance in trained athletes? (2015)

This randomized, double-blind, crossover study examined the effects of a clothing ensemble made of a synthetic fabric promoted as having superior cooling properties (COOL) on exercise performance and its physiological and perceptual determinants during cycle exercise in ambient laboratory conditions that mimic environmental conditions of indoor training/sporting facilities. Twenty athletes (15 men:5 women) aged 25.8 ± 1.2 years (mean ± SEM) with a maximal rate of O2 consumption of 63.7 ± 1.5 mL·kg(-1)·min(-1) completed cycle exercise testing at 85% of their maximal incremental power output to exhaustion while wearing an ensemble consisting of a fitted long-sleeved shirt and full trousers made of either COOL or a synthetic control fabric (CTRL). Exercise endurance time was not different under COOL versus CTRL conditions: 12.38 ± 0.98 versus 11.75 ± 1.10 min, respectively (P > 0.05). Similarly, COOL had no effect on detailed thermoregulatory (skin and esophageal temperatures), cardiometabolic, ventilatory, and perceptual responses to exercise (all P > 0.05). In conclusion, clothing made of a synthetic fabric with purported "cooling" properties did not improve high-intensity cycle exercise endurance in trained athletes under ambient laboratory conditions that mimic the environmental conditions of indoor training/sporting facilities.
Area-Efficient Parallel FIR Digital Filter Structures for Symmetric Convolutions Based on Fast FIR Algorithm (2011)

Based on fast finite-impulse response (FIR) algorithms (FFAs), this paper proposes new parallel FIR filter structures, which are beneficial to symmetric coefficients in terms of the hardware cost, under the condition that the number of taps is a multiple of 2 or 3. The proposed parallel FIR structures exploit the inherent nature of symmetric coefficients reducing half the number of multipliers in subfilter section at the expense of additional adders in preprocessing and postprocessing blocks. Exchanging multipliers with adders is advantageous because adders weigh less than multipliers in terms of silicon area; in addition, the overhead from the additional adders in preprocessing and postprocessing blocks stay fixed and do not increase along with the length of the FIR filter, whereas the number of reduced multipliers increases along with the length of the FIR filter. For example, for a four-parallel 72-tap filter, the proposed structure saves 27 multipliers at the expense of 11 adders, whereas for a four-parallel 576-tap filter, the proposed structure saves 216 multipliers at the expense of 11 adders still. Overall, the proposed parallel FIR structures can lead to significant hardware savings for symmetric convolutions from the existing FFA parallel FIR filter, especially when the length of the filter is large.
Computing curvilinear structure by token-based grouping (2003)

A computational framework for computing curvilinear structure on the edge data of images is presented. The method is symbolic, operating on geometric entities/tokens. It is also constructive, hierarchical, parallel, and locally distributed. Computation proceeds independently at each token and at each stage interleaves the discovery of structure with its careful description. The process yields a hierarchy of descriptions at multiple scales. These multiscale descriptions provide efficient feature indexing both for the grouping process itself as well as for subsequent recognition processes. Experimental results are presented to demonstrate the effectiveness of the approach with respect to curvilinear structure, and its application to more general grouping problems is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A novel bipolar imaging device with self-noise-reduction capability (1989)

A bipolar image sensor with charge amplification and noise-reduction capabilities in each unit cell is discussed. The dynamic range of linearity in the photoelectric conversion characteristics has been greatly extended by using capacitor-loaded emitter-follower circuitry and a readout operation in a deep forward-base-emitter-biasing condition. The fixed pattern noise and the random noise are reduced by introducing a hybrid reset operation that is a combination of the clamp reset and the transient reset.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A CMOS Image Sensor with a Buried-Channel Source Follower (2008)

This paper presents a CMOS image sensor with a pinned-photodiode 4T active-pixel design (APS) that uses a buried-channel source follower (BSF) as the in-pixel amplifier. A prototype of the image sensor has been fabricated in a 0.18mum CMOS process. Measurements show that compared to a regular imager with a standard nMOS transistor surface-mode source follower (SSF), the new pixel structure reduces dark random noise by more than 50% and improves output swing by almost 100%.
Recombination between defective tombusvirus RNAs generates functional hybrid genomes. (1994)

The tombusviruses represent a group of small icosahedral plant viruses that contain monopartite positive-sense RNA genomes. Tombusviruses are able to generate small replicating deletion mutants of their genomes (i.e., defective interfering RNAs) during infections via RNA recombination and/or rearrangement. To further study the process of RNA recombination and to determine whether tombusviruses were capable of trans-recombination, protoplasts were coinoculated with in vitro-generated transcripts of a nonreplicating 3'-truncated genomic RNA of cucumber necrosis tombusvirus and either replicative or replication-defective DI RNAs of tomato bushy stunt tombusvirus. After a 48-hr incubation, two dominant replicative chimeric recombinant viral RNA populations were detected that contained various large contiguous 5' segments of the cucumber necrosis tombusvirus genomic RNA fused to 3'-terminal regions of the tomato bushy stunt tombusvirus defective interfering RNA. Some of the larger chimeric recombinants formed in protoplasts were able to systemically infect plants and induce wild-type symptoms. In addition, a functional chimeric genome was generated in planta after direct coinoculation of whole plants with the defective RNA components. These results indicate that (i) RNA recombination can occur relatively efficiently in single-cell infections, (ii) trans-recombination can occur with nonreplicating viral RNA components, and (iii) functional chimeric genomes can be generated via recombination. Possible mechanisms for the formation of the recombinants are proposed, and evolutionary implications are discussed.
Preservation of Indium Phosphide Substrates: The In‐Sn‐P Melt Revisited (1986)

Using Auger electron spectroscopy and secondary ion mass spectrometry, we have detected very high levels of tin (∼ 1021/cm3) on (100) substrates preserved at high temperatures (650°–700°C) with phosphorus vapor supplied by an In‐Sn‐P solution. Depth profiling through epilayers grown on preserved substrates, however, indicates no tin buildup at the epilayer/substrate interface. Surface studies and depth profiling of control samples reveal that the tin accumulated during preservation is restricted to the near‐surface region (≲ 10Å) and readily dissolves into an In‐P melt.
Polymerization of Several Proteins by Ca<sup>2+</sup>-Independent Transglutaminase Derived from Microorganisms (1989)

αs1-Casein and soybean globulins were polymerized and gelatinized by Ca2+-independent transglutaminase that was isolated from the culture filtrate of a microorganism thought to belong to Streptoverticillium sp. of actinomycetes. This enzyme polymerized such albumins as bovine serum albumin, human serum albumin and conalbumin in the presence of dithiothreitol. Rabbit myosin was polymerized by the present emzyme but actin was not. An RP-HPLC analysis after enzymic digestion of the polymerized asl -casein showed existence of the £-(y-Glu)Lys bond. Thus, it was confirmed that the polymerization was formed by a catalytic reaction of the transglutaminase.
