Instantaneous planar pressure field determination around a square-section cylinder based on time resolved stereo-PIV (2008)

Particle image velocimetry (PIV) has proven its strength as a flow diagnostic tool to characterise instantaneous velocity fields and derived quantities such as vorticity. Recent efforts apply momentum conservation principles on planar velocity data in order to extract more quantities, such as pressure fields and integral aerodynamic forces. The theoretical concepts for this ‘planar pressure imaging’
Tension-free vaginal tape: why an unusual concept is so successful (2001)

The surgical treatment of female stress urinary incontinence has been dramatically changed during the last 5 years, after Ulmsten introduced the tension-free vaginal tape procedure. This technique is based on a series of experimental investigations of the urethral closure mechanisms in women. The procedure is easy to learn, could be performed on an outpatient basis, and is recognized as a minimally invasive surgery. Despite these arguments, the most probable reason for its present success is the reproducibility of the results in the various published series. The success rate is estimated at between 85 and 95% for correction of genuine stress urinary incontinence. However, longer follow-up will be necessary to confirm these preliminary results, and probably to determine what are the most valuable prognostic factors.

Threshold Signcryption Based on Elliptic Curve (2009)

The signcryption scheme presented by Zheng uses hash function and symmetrical cipher to encrypt message. The first protocol for threshold generation of Zhengpsilas signcryption scheme couldnpsilat support multiple public verifiers. In this paper, we proposed a new signcryption scheme based on EC-ELGamal type encryption. Message to be transmitted is embedded in Elliptic Curve as a point P(m) and encrypted by point addition which is efficient and secure as well as exiting schemes. By using verifiable secret sharing and secure multi-party computation, we propose a protocol for threshold generation of the signcryption. Because point addition couldnpsilat map coordinate addition directly, we introduce a linear sum of coordinates to reconstruct the private coordinate. The protocol supports k out of n senders and the public verifier. The specific receiver can verify the validity of the signature before decrypting the cipher. The proposed protocol is a perfect threshold scheme. Thus, it can defend the attack launched by k-1 players. Complexity of them is less than the same schemes based on DLP (Discrete Logarithm Problem).
Separation and characterization of four enzyme forms of β‐galactosidase from <i>Saccharomyces lactis</i> (1988)

beta-Galactosidase from Saccharomyces lactis has been purified to serve as a model for the kinetic behavior of human lactase in adult lactase deficiency. Enzymes from both species are neutral and follow Michaelis-Menten kinetics. beta-Galactosidase of S. lactis is more readily available than the human lactase. An enzyme preparation from S. lactis (Maxilact 40,000), which is used commercially to hydrolyze lactose in milk, has been found to contain four isozymes of beta-galactosidase. Methods have been developed for the separation and purification of each of the four enzymes. The enzymes were found to differ in molecular mass, kinetic behavior, isoelectric point, response to pH, specific volume and sensitivity to metal ions. The four enzymes had apparent molecular masses of 630 kDa, 550 kDa, 41 kDa and 19 kDa. Their specificity constants (kcat/Km) were found to be 42.0, 355.2, 0.38 and 0.48 mM-1 s-1, respectively. The techniques of reiterated ultrafiltration used for the isolation of these isozymes may be applicable to other purification processes.
On the nature and reduction of plaque‐mimicking flow artifacts in black blood MRI of the carotid bifurcation (1998)

Cardiac-gated black blood MRI of the carotid artery bifurcation in normal human subjects shows signal within the lumen suggesting wall thickening or atherosclerotic plaque. This signal was believed to be artifactual, arising from complex flow patterns present at the carotid bifurcation. Computer simulation of the hemodynamics and black blood multislice image acquisition in a model of the carotid bifurcation showed that these artifacts arise from spins recovering their signal within the slow, recirculating flow of the carotid bulb. The computed hemodynamics also suggested that these artifacts could be minimized or eliminated entirely by gating the acquisition of slices in the most artifact-prone region of the carotid bulb within a 250-ms window after peak systole. Application of these predictions to studies of normal volunteers showed that, in most cases, these flow artifacts in black blood MRI can be eliminated simply by altering the phase of the cardiac cycle to which the image acquisition is gated. The observation that the size and placement of the saturation slabs had little effect on these artifacts suggested that, in those cases in which recirculation persists throughout the cardiac cycle, either inversion-recovery or presaturation within the bulb itself would be required to suppress them.
Reactions with Heterocyclic Amidines, XI. Syntheses of New 2‐Aminopyrazolo[1,5—a]pyrimidines and 2‐Amino[1,5‐c]‐as‐triazines (1983)

Abstract Several new aminopyrazolo[1,5— a ]pyrimidines were synthesised by condensation of 3,5‐diamino‐4‐(ethoxycarbonyl)pyrazole (1) with β‐bifunctional reagents. The azo analogues of pyrazolo[1,5— a ]pyrimidines, i. e. pyrazolo[1,4‐ c ]‐ as ‐triazines, were synthesised by coupling of diazotized 1 with agents containing active hydrogen.
Range of Perceived Hues in Two-Primary Projections (1970)

Hues perceived in two-primary projections were predicted for all combinations of pairs of 31 different spectral primaries by use of our computerized version of the Helson–Judd formulation. The computer was instructed to note the absence from the predicted hues of any of the full possible complement of red, yellow–red, yellow, green–yellow, green, blue–green, blue, and red–blue. Experimental confirmation of the computations is reported, based on color naming by trained subjects of the cells in computer-generated quilts projected with a selection of near-spectral primaries. The results of these investigations confirm the usefulness of the Helson–Judd formulation as a means of translating from chromaticity to perceived color in colored displays.

Effects of Thyroidectomy and Thyroxine on Plasma Growth Hormone and Insulin Levels in Rats (1977)

Plasma growth hormone and insulin levels were measured in normal, thyroidectomized (Tx), and Tx rats treated with 1-thyroxine (1-T4) or rat-growth hormone (r-GH). Although normal growth was observed 5 days after surgery, a decrease of circulating levels of GH was evidenced as early as 5 days after the operation. However, the plasma insulin levels were not affected by the 5th, 10th and 15th day of thyroidectomy. With a more prolonged thyroid hormone deprivation, the plasma insulin levels of Tx rats remained lower than those of age-paired controls. Treatment of hypothyroid rats with 0.05 µg 1-T4 for 10 days induced growth and an increase in circulating GH levels, but had no effect on the low levels of plasma insulin of Tx rats. Treatment of Tx animals with 0.10 or 0.20 µg 1-T4, or 100 µg r-GH during 10 days caused plasma insulin levels to shift toward the values of their weight-paired controls. However, treatment of hypophysectomized (Hx) rats with 0.20 µg T4 during 8 days did not change the circulating levels of plasma insulin. It is suggested that thyroid hormone deprivation results in a decrease of circulating levels of insulin secondary to a deficiency in growth hormone secretion. In addition, normal GH secretion appears to be required for normal pancreatic insulin secretion to occur.
Cell‐Specific Expression of the Mouse Glial Fibrillary Acidic Protein Gene: Identification of the <i>Cis</i>‐ and <i>Trans</i>‐Acting Promoter Elements for Astrocyte‐Specific Expression (1990)

We have determined the whole promoter sequence and the transcriptional startpoint of the mouse glial fibrillary acidic protein (GFAP) gene and characterized the promoter function. We found that the cis elements for astrocyte specific expression are located within 256 bp from the transcription startpoint. We defined by DNase I footprinting assay three trans-acting factor binding sites (GFI, GFII, and GFIII) using brain or C6 astrocytoma nuclear extracts. GFI, GFII, and GFIII have AP-2, NFI, and cyclic AMP-responsive element motifs, respectively. Mutations in GFII drastically decreased the promoter activity. Base substitution in GFI and GFIII abolished the cell-specific expression, resulting in the GFAP promoter expression even in some non-GFAP-producing cells.
LISP-DHT (2008)

Recent activities in the IRTF (Internet Research Task Force), and in particular in the Routing Research Group (RRG), focus on defining a new Internet architecture, in order to solve scalability issues related to interdomain routing. The research community has agreed that the separation of the end-systems' addressing space (the identifiers) and the routing locators' space will alleviate the routing burden of the Default Free Zone. Nevertheless, such approach, adding a new level of indirection, implies the need of storing and distributing mappings between identifiers and routing locators. In this paper we present LISP-DHT, a mapping distribution system based on Distributed Hash Tables (DHTs). LISP-DHT is designed to take full advantage of the DHT architecture in order to build an efficient and secured mapping lookup system while preserving the locality of the mapping. The paper describes the overall architecture of LISP-DHT, explaining its main points and how it works.
Multiple Phase Transitions of Starches and Nägeli Amylodextrins (1980)

Abstract At temperatures above that required for gelatinization, an order‐disorder transition is observed for wheat, maize, waxy maize and potato starches. This transition is the melting of the crystallites in the granules. A second, higher temperature, transition occurs in wheat and maize starches. This also appears to be a melting transition. Potato starch Nägeli amylodextrins show increased thermal stability of the crystalline regions with increasing hydrolysis of the amorphous regions. Extensive hydrolysis lessens the destabilizing effect of the amorphous regions on the crystallites sufficiently that the gelatinization transition occurs to only a small extent, the crystalline regions melting, instead, at temperatures above the gelatinization temperature.
Multichannel reservation protocols for satellite multiple access networks (2002)

The author presents a class of multichannel reservation protocols (MRPs) which treat all multiple channels required to accommodate the traffic in a large satellite network as a common resource. The MRPs are a class of protocols for star-configured satellite networks with multiple inbound channels and bursty traffic sources generating a mixture of long and short data messages. The MRPs employ slotted random access with immediate retransmissions, and reservation of consecutive time slots for multipacket messages. Delay-throughput characteristics are derived under steady-state equilibrium conditions and presented in graphs. These results show that MRPs achieve higher throughput capacity than random access protocols and lower average delay than other reservation protocols.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Performance of a YSO/LSO phoswich detector for use in a PET/SPECT system (1997)

The performance of a YSO/LSO phoswich detector module is evaluated for potential use as in a combined PET/SPECT imaging system. The high light output of LSO (/spl sim/5-6 times EGO) would allow the construction of a detector block that would have similar intrinsic resolution characteristics at 140 keV as a conventional high resolution EGO block detector at 511 keV (/spl sim/4 mm FWHM). However, the intrinsic radioactivity of LSO prevents the use of this scintillator in single photon counting mode. YSO is a scintillator with higher light output than LSO but worse absorption characteristics than LSO at higher energies. In a phoswich detector block the two detector materials are combined, where YSO is placed in a front layer and is used for single photon imaging and LSO in a second layer is used for PET imaging. Since the scintillation decay times in YSO and LSO are significantly different (70 and 40 ns, respectively), events in the two detector materials can be separated by pulse shape discrimination. In measurements of the system resolution using a high resolution collimator, the spatial resolution at 10 cm collimator distance was 8.5 mm for the phoswich detector compared to 7.6 mm for a conventional scintillation camera. However, in SPECT simulations of the two detector systems of a 20 cm diameter hot spot phantom imaged at different collimator distances using a high resolution collimator, no appreciable difference in resolution was seen in the reconstructed images between the two camera systems, including the ideal situation of zero distance between collimator and phantom.
A single base change prevents import of cytosolic tRNA<sup>Ala</sup> into mitochondria in transgenic plants (1996)

Plant mitochondria do not contain a full set of tRNA genes, and the additional tRNAs needed for protein synthesis (including tRNA(Ala) are imported from the cytosol. The import process appears to be highly specific for certain tRNAs, and it has been suggested that the cognate amino-acyl-tRNA synthetases may be responsible for this specificity. In order to test this, we have grown transgenic tobacco plants expressing Arabidopsis thaliana tRNA(Ala) carrying a U70 to C70 mutation, which we have previously shown blocks aminoacylation by the plant alanyl-tRNA synthetase. Unlike the wild-type tRNA(Ala), the mutant tRNA is not present in the mitochrondrial tRNA fraction. This is the first report of a tRNA mutation which prevents mitochondrial import and strongly supports the hypothesis that aminoacyl-tRNA synthetases are involved in this process in plants. Insertion of four bases into the anticodon loop of tRNA(Ala) does not prevent mitochondrial import, implying that the tRNA might not need to participate in translation to be imported.
Resume Information Extraction with A Novel Text Block Segmentation Algorithm (2019)

In recent years, we have witnessed the rapid development of deep neural networks and distributed representations in natural language processing. However, the applications of neural networks in resume parsing lack systematic investigation. In this study, we proposed an end-to-end pipeline for resume parsing based on neural networks-based classifiers and distributed embeddings. This pipeline leverages the position-wise line information and integrated meanings of each text block. The coordinated line classification by both line type classifier and line label classifier effectively segment a resume into predefined text blocks. Our proposed pipeline joints the text block segmentation with the identification of resume facts in which various sequence labelling classifiers perform named entity recognition within labelled text blocks. Comparative evaluation of four sequence labelling classifiers confirmed BLSTM-CNNs-CRF's superiority in named entity recognition task. Further comparison among three publicized resume parsers also determined the effectiveness of our text block classification method.
Speech Animation Using Coupled Hidden Markov Models (2006)

We present a novel speech animation approach using coupled hidden Markov models (CHMMs). Different from the conventional HMMs that use a single state chain to model the audio-visual speech with tight inter-modal synchronization, we use the CHMMs to model the asynchrony, different discriminative abilities, and temporal coupling between the audio speech and the visual speech, which are important factors for animations looking natural. Based on the audio-visual CHMMs, visual animation parameters are predicted from audio through an EM-based audio to visual conversion algorithm. Experiments on the JEWEL AV database show that compared with the conventional HMMs, the CHMMs can output visual parameters that are much closer to the actual ones. Explicit modelling of audio-visual speech is promising in speech animation
Role of Androgen Metabolism Genes <i>CYP1B1, PSA/KLK3</i>, and <i>CYP11α</i> in Prostate Cancer Risk and Aggressiveness (2005)

Candidate genes involved with androgen metabolism have been hypothesized to affect the risk of prostate cancer. To further investigate this, we evaluated the relationship between prostate cancer and multiple potentially functional polymorphisms in three genes involved in androgen metabolism: CYP1B1 (two single nucleotide polymorphisms: 355G/T and 4326C/G), prostate-specific antigen (PSA/KLK3 (three single nucleotide polymorphisms: -158A/G, -4643G/A, and -5412C/T), and CYP11alpha [(tttta)(n) repeat], using a moderately large (n = 918) sibling-based case-control population. When looking at all subjects combined, no association was observed between any polymorphism-or their haplotypes-and prostate cancer risk. However, among men with more aggressive prostate cancer, the CYP1B1 355G/T variant was positively associated with disease: carrying one or two T alleles gave odds ratios (OR) of 1.90 [95% confidence interval (95% CI), 1.09-3.31; P = 0.02] and 3.73 (95% CI, 1.39-10.0; P = 0.009), respectively. Similarly, carrying the CYP1B1 355T-4326C haplotype was positively associated with prostate cancer among men with high aggressive disease (P = 0.01). In addition, the PSA -158G/-158G genotype was positively associated with prostate cancer among men with less aggressive disease (OR, 2.71; 95% CI, 1.06-6.94; P = 0.04). Our findings suggest that CYP1B1 and PSA variants may affect the risk of prostate cancer and tumor aggressiveness.
Cyclin-dependent kinases as targets for cancer therapy. (2002)

With the overwhelming evidence that the majority of human neoplasms are the result of 'cdk hyperactivation' leading to the abrogation of the Rb pathway, novel direct and indirect cdk inhibitors are being developed. The first 2 direct cdk inhibitors tested in clinical trials, flavopiridol and UCN-01, showed promising results with some evidence of antitumor activity reaching plasma concentrations effective to inhibit cdk-related functions. Other indirect cdk inhibitors such as PS-341, perifosine are also being tested in the clinic. The best schedule of administration, combination with standard chemotherapeutic agents, determination of predictive markers (using novel technologies such as cDNA arrays) for response/toxicity and demonstration of cdk modulation from tumor samples from patients in these trials are important issues that need to be answered in order to obtain the best possible results with these agents.
Address-event imagers for sensor networks: evaluation and modeling (2006)

Although imaging is an information-rich sensing modality, the use of cameras in sensor networks is very often prohibited by factors such as power, computation cost, storage, communication bandwidth and privacy. In this paper we consider information selective and privacy-preserving address-event imagers for sensor networks. Instead of providing full images with a high degree of redundancy, our efforts in the design of these imagers specialize on selecting a handful of features from a scene and outputting these features in address-event representation. In this paper we present our initial results in modeling and evaluating address-event sensors in the context of sensor networks. Using three different platforms that we have developed, we illustrate how to model address-event cameras and how to build an emulator using these models. We also present a lightweight classification scheme to illustrate the computational advantages of address-event sensors. The paper concludes with an evaluation of the classification algorithm and a feasibility study of using COTS components to emulate address-event inside a sensor network.
Piecewise-linear timing delay modeling for digital CMOS circuits (1988)

A simple and accurate timing delay characterization algorithm for digital complementary metal-oxide-semiconductor (CMOS) circuits is presented. To reflect various nonlinear effects in metal-oxide-semiconductor circuits, the author uses reliable circuit simulations and measurements to generate various timing data for the most typical subcircuit structures with various driving and loading conditions. The huge data set is curve-fitted into simple piecewise-linear functions, which are stored in a timing library. Great efficiency and reliable accuracy are achieved on an experimental simulator based on the precharacterized timing library.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimum motion estimation algorithm for fast and robust digital image stabilization (2006)

To realize fast and robust digital image stabilization, in this paper, we propose a new optimum motion estimation algorithm under various illuminations, occlusion and blooming. In this algorithm, we expand our original fast template matching method named HDTM (hierarchical distributed template matching). First, only useful reference blocks that are indispensable for accurate motion estimation are selected with its reliability and consistency on pose estimation. Next, using the LMedS method, motion vectors of these blocks are segmented to some groups and only reliable ones are used for whole motion estimation. With experimental results, we could see small errors less than /spl plusmn/0.1 pixels, /spl plusmn/0.1 degrees and /spl plusmn/0.1% scales were achieved under various kinds of disturbance. And the processing time was 11 msec with PII-300 MHz CPU in typical case. It is enough to realize real-time processing for embedded use of image stabilization.
Viral Classification and Nomenclature (2006)

Abstract As any classification is essentially an arbitrary human invention it is imperative to have a unique source of virus classification. The International Committee on Taxonomy of Viruses and the Virology Division of the International Union of Microbiological Societies have been in charge of this task since 1966.
Characterization of three-phase unbalanced dips (as easy as one-two-three?) (2002)

A proposal is presented for characterization of voltage dips as experienced by a three-phase load. The primary result of the method is a so-called "characteristic magnitude" which corresponds to the magnitude (remaining voltage) as used for the existing methods to characterize dips experienced by a single-phase load. The proposed method may be extended by adding additional parameters where further accuracy is needed for characterization. The method is applied to the analysis of multi-stage voltage dips.
