Reconstruction of 3D mannequin by two-dimensional photos (2008)

This paper introduce a new way to build the individuated 3D human body modeling by using two 2D photos to reconstruct 3D Mannequins which including 3D human body modeling and 3D human face modeling. Our work mainly concentrates in extracting human body feature points from 2D photos by the theory of anthropometry and converting these feature points to deformation parameters which will be applied to the initial 3D model of the human body.
Purification and Characterization of a Lipase from<i>Aspergillus oryzae</i> (1995)

A lipase from Aspergillus oryzae was purified by ammonium sulfate fractionation, anion exchange chromatography, hydrophobic interaction chromatography, and anion exchange chromatography. The purified enzyme was a monomeric protein with a molecular mass of 41 kDa estimated by SDS-PAGE and 39 kDa by gel filtration. The optimum pH at 30 degrees C and optimum temperature at pH 7.0 were 7.0 and 30 degrees C, respectively. The enzyme was stable over a pH range of 6-9 at 25 degrees C for 18 h, and up to 30 degrees C at pH 7.0 for 3 h. Ag+, Fe3+, Hg2+, Cu2+, and Zn2+ inhibited the enzyme activity severely. The enzyme was a lipase that hydrolyzed monoacylglycerols and diacylglycerols, but did not hydrolyze triacylglycerols. The N-terminal amino acid sequence of the enzyme was highly homologous with that of the mono- and diacylglycerol lipase from Penicillium camembertii U-150.
Effect of Strong Electric Field on the Conformational Integrity of Insulin (2014)

A series of molecular dynamics (MD) simulations up to 1 μs for bovine insulin monomer in different external electric fields were carried out to study the effect of external electric field on conformational integrity of insulin. Our results show that the secondary structure of insulin is kept intact under the external electric field strength below 0.15 V/nm, but disruption of secondary structure is observed at 0.25 V/nm or higher electric field strength. Although the starting time of secondary structure disruption of insulin is not clearly correlated with the strength of the external electric field ranging between 0.15 and 0.60 V/nm, long time MD simulations demonstrate that the cumulative effect of exposure time under the electric field is a major cause for the damage of insulin's secondary structure. In addition, the strength of the external electric field has a significant impact on the lifetime of hydrogen bonds when it is higher than 0.60 V/nm. The fast evolution of some hydrogen bonds of bovine insulin in the presence of the 1.0 V/nm electric field shows that different microwaves could either speed up protein folding or destroy the secondary structure of globular proteins deponding on the intensity of the external electric field.
Metabolism of Puromycin Aminonucleoside in the Normal, "Pre-Nephrotic," and Nephrotic Rat. (1967)

Approximately 80% of injected aminonucleoside-8-C14 is excreted in the urine and feces within 24 hrs by the rat. The principal urinary products are unchanged amino-nucleoside, the monodemethylated analog, and allantoin. Daily administration of aminonu-cleoside for 12 days did not influence the course of its own metabolism.

An automatic and accurate x‐ray tube focal spot/grid alignment system for mobile radiography: System description and alignment accuracya) (2010)

The mobile radiography AGAS produces images of significantly improved quality compared to nongrid images with alignment times of less than 10 s and no increase in patient dose.
Endovascular Therapy for Ruptured Cerebral Aneurysms in the Elderly (2015)

Increasing age was correlated with poor accessibility of the guiding catheter in endovascular embolization of ruptured intracranial aneurysms. Distally located aneurysms treated through a low-positioned guiding catheter and use of local anesthesia increased the risk of procedure-related rupture.
New approach to moisture accumulation assessment (2019)

We suggest an innovative approach to simulate moisture buildup on structures with arbitrary geometries and different surface adhesion characteristics. Using 3D particle physics, rain, snow and freezing rain buildup on flat and cylindrical surfaces was assessed. The numerically simulated moisture accumulations were subsequently successfully verified experimentally through a series of outdoor and indoor moisture accumulation experiments. We also conducted molecular dynamics simulations to assess how hydrogen bonds influence snow and rain adhesion on high and low energy substrates. The simulations supported the experimental observations, namely that freezing rain results in increased moisture adhesion and accumulation due to the spreading of the water droplets, resulting in more hydrogen bonds between water droplets and substrates than snow.
OPT: Optimal Protocol Tree for Efficient Tag Identification in Dense RFID Systems (2006)

We propose a novel collision resolution scheme termed the Optimal Protocol Tree (OPT), which is based on the tree search algorithm for RFID systems. The basic principle of OPT relies on taking advantage of the similarities in the identification strings of different tags, having the reader prompt the tags to send only the mutually exclusive sub-portion of their identification strings. The aim of OPT is to significantly reduce the total identification time, in order to render the deployment of dense RFID systems feasible. Simulation results are presented to demonstrate the performance of OPT, and the considerable improvement it provides with respect to the existing tree search protocols.
Intra-Abdominal Adhesions and Their Prevention by Topical Tissue Plasminogen Activator (1989)

Recent work shows that a common pathway in adhesion production is a reduction in local plasminogen activator activity (PAA). This deficit permits deposited surface fibrin to become organized to fibrous adhesions. A rabbit model for adhesion formation was used to assess the effect of replacing the deficit with recombinant tissue plasminogen activator (rt-PA). Adhesions were produced by stripping peritoneum from corresponding parietal and visceral areas. One week later the adhesions were divided. Either rt-PA or placebo was applied to the divided adhesion. After a further week the animal was killed and the adhesions assessed. Sixty strips were performed. Fifty-five adhesions were produced (92%). Placebo gel was applied to 28 sides and rt-PA applied to 27. Twenty-two of the placebo group recurred (79%). Two of the rt-PA group reformed (7%, chi 2 = 20.883, P less than 0.001). Recombinant tissue plasminogen activator is an effective inhibitor of adhesion formation in the experimental animal.
A new encoding based genetic algorithm for the traveling salesman problem (2006)

The combination of genetic algorithm and local search has been shown to be an effective approach to solve the traveling salesman problem. In this article, a genetic algorithm based on a novel encoding scheme which converges to a global optimal solution with probability 1 is proposed, in which a new local search scheme is combined into the proposed genetic algorithm. In the proposed algorithm, a new chromosomal encoding scheme and a new crossover operator are described and a new local search scheme is used to improve the quality of the offspring generated by the crossover. The new local search scheme is not an exact local optimization algorithm, but a scheme that can generate good enough solutions using much less computation than general local optimization search algorithms. Moreover, both the crossover operator and the local search scheme are very easy to execute, and the offspring generated by them always represent valid tours. Furthermore, the convergence of the proposed algorithm to a globally optimal solution with probability 1 is proved. Finally, the experimental results on nine standard benchmark problems show the efficiency of the proposed algorithm.
Design and signaling mechanism of light‐regulated histidine kinases (2009)

Signal transduction proteins are organized into sensor (input) domains that perceive a signal and, in response, regulate the biological activity of effector (output) domains. We reprogrammed the input signal specificity of a normally oxygen‐sensitive, light‐inert histidine kinase by replacing its chemosensor domain by a light‐oxygen‐voltage (LOV) photosensor domain. Illumination of the resultant fusion kinase YF1 reduced net kinase activity by ~1000‐fold in vitro. YF1 also controls gene expression in a light‐dependent manner in vivo. Signals are transmitted from the LOV sensor domain to the histidine kinase domain via a 40‐60º rotational movement within an α‐helical coiled coil linker; light is acting as a rotary switch. These signaling principles are broadly applicable to domains linked by α‐helices, and to both chemo‐ and photosensors. Conserved sequence motifs guide the rational design of light‐regulated variants of histidine kinases and other proteins. Funded by NIH grant GM036452 to K.M.
Analysis of methotrexate and folate transport by multidrug resistance protein 4 (ABCC4): MRP4 is a component of the methotrexate efflux system. (2002)

Human MRP4 (ABCC4, MOAT-B) is a lipophilic anion transporter that is able to confer resistance to nucleotide analogues and methotrexate (MTX). We previously investigated the implications of the ability of MRP4 to confer resistance to nucleotide analogues and determined that the pump is competent in the MgATP-energized transport of cyclic nucleotides and estradiol 17beta-D-glucuronide. Here we examine the potential role of MRP4 in conferring resistance to MTX and related processes by determining the selectivity of the transporter for MTX, MTX polyglutamates, and physiological folates. In so doing, it is shown that MRP4 is active in the transport of MTX as well as the physiological folates folic acid (FA) and N(5)-formyltetrahydrofolic acid (leucovorin). MTX, FA, and leucovorin are subject to high capacity [V(max(MTX)), 0.24 +/- 0.05 nmol/mg/min; V(max (FA)), 0.68 +/- 0.14 nmol/mg/min; V(max(leucovorin)), 1.95 +/- 0.18 nmol/mg/min], low affinity [K(m(MTX)), 0.22 +/- 0.01 mM; K(m(FA)), 0.17 +/- 0.02 mM; K(m (leucovorin)), 0.64 +/- 0.23 mM] transport by MRP4. In addition, as would be expected were MRP4 a component of the MTX efflux system, its capacity to transport this agent is abrogated by the addition of a single glutamyl residue. It is also shown that glutamylation similarly affects the ability of MRP2 to transport MTX. On the basis of these transport properties, it is concluded that the efflux system for MTX includes MRP2 and MRP4, in addition to MRP1 and MRP3, and that MRP4 represents a common efflux system for both MTX and certain nucleotide analogues.
Comparison of short-time Fourier, wavelet and time-domain analyses of intracardiac sounds. (1993)

Heart sounds provide clinicians with valuable diagnostic and prognostic information. They are repetitive in nature, but reflect complex mechano-acoustical events which have been inadequately described by traditional digital signal processing methods. In this study, left ventricular and aortic intravascular phonocardiograms were obtained from six patients by catheter-mounted piezoelectric transducers. Phonocardiograms (PCGs) were bandpass filtered (50-500 Hz), digitized at 4kHz and analyzed by three separate techniques: (1) Short-Time Fourier Transform (STFT), (2) Fast Wavelet Transform (FWT), and (3) a pulse-counting time-domain method based on an Order Statistic (OS) filter. The resulting time-frequency distributions were employed to examine intra-patient and inter-patient acoustic variability. Results suggest that STFT and FWT provide comparable temporal and frequency resolution of cardiac acoustical events. However, the time-varying and multicomponent nature of heart sounds was poorly characterized by the OS technique employed in this study. This study suggests that improved localization of acoustic events during the cardiac cycle may prove useful in the development of automated auscultation devices.

INVESTIGATION ON THE MECHANISM OF DISSOLUTION OF COAL FULVIC ACID IN ORGANIC SOLVENTS (1982)

A series of solvents is suggested for studying the dissolution mechanism of the fulvic acid from Gongxian weathered coal. It has been found that the solubilities of the fulvic acid in different organic solvents depend mainly on the solvent's parameter δ_a which represents the hydrogen bonding ability of the solvent i.e. the solubility of the coal fulvic acid increases with the δ_a value of the solvent. These fractions separated by various solvents have been chararcterized by elemental and functional group analyses, IR and ~(13)C NMR. The results show that the regular changos of aromaticity and quinonoic contents in different fractions are in agreement with the proposed dissolution mechanism in which the formation of hydrogen bonding is regarded as the leading factor in dissolution.
Langerhans Cell Histiocytosis (1987)

Nearly a century has passed since Alfred Hand reported a case of "polyuria and tuberculosis,"1 later considered to be the first case of the Hand-Schül1er–Christian syndrome. Although early investigators considered this syndrome pathologically distinct from Letterer–Siwe disease, the later recognition of eosinophilic granuloma of bone as part of the same spectrum led Lichtenstein to propose the pathologically inclusive term "histiocytosis X" for the varying clinical manifestations.2 Modern pathological techniques have revealed the identity of the offending cell, and we can now call this disorder by its proper name, Langerhans cell histiocytosis.3 The Langerhans cell is a dendritic cell derived from . . .
Atmospheric Hydrogenation of Esters Catalyzed by PNP-Ruthenium Complexes with an <i>N</i>-Heterocyclic Carbene Ligand (2016)

New pincer ruthenium complexes bearing a monodentate N-heterocyclic carbene ligand were synthesized and demonstrated as powerful hydrogenation catalysts. With an atmospheric pressure of hydrogen gas, aromatic, heteroaromatic, and aliphatic esters as well as lactones were converted into the corresponding alcohols at 50 °C. This reaction protocol offers reliable access to alcohols using an easy operational setup.
Performance‐driven muscle‐based facial animation (2001)

We describe a system to synthesize facial expressions by editing captured performances. For this purpose, we use the actuation of expression muscles to control facial expressions. We note that there have been numerous algorithms already developed for editing gross body motion. While the joint angle has direct effect on the configuration of the gross body, the muscle actuation has to go through a complicated mechanism to produce facial expressions. Therefore,we devote a significant part of this paper to establishing the relationship between muscle actuation and facial surface deformation. We model the skin surface using the finite element method to simulate the deformation caused by expression muscles. Then, we implement the inverse relationship, muscle actuation parameter estimation, to find the muscle actuation values from the trajectories of the markers on the performer's face. Once the forward and inverse relationships are established, retargeting or editing a performance becomes an easy job. We apply the original performance data to different facial models with equivalent muscle structures, to produce similar expressions. We also produce novel expressions by deforming the original data curves of muscle actuation to satisfy the key-frame constraints imposed by animators.Copyright © 2001 John Wiley & Sons, Ltd.
Learning coarse correlated equilibria in two-tier wireless networks (2012)

In this paper, we study the strategic coexistence between macro and femto cell tiers from a game theoretic learning perspective. A novel regret-based learning algorithm is proposed whereby cognitive femtocells mitigate their interference toward the macrocell tier, on the downlink. The proposed algorithm is fully decentralized relying only on the signal-to-interference-plus-noise ratio (SINR) feedback to the corresponding femtocell base stations. Based on these local observations, femto base stations learn the probability distribution of their transmission strategies (power levels and frequency band) by minimizing their regrets for using certain strategies, while adhering to the cross-tier interference constraint. The decentralized regret based learning algorithm is shown to converge to an ϵ-coarse correlated equilibrium (ϵ-CCE) which is a generalization of the classical Nash Equilibrium (NE). Finally, numerical results are shown to corroborate our findings where, quite remarkably, our learning algorithm achieves the same performance as the classical regret matching, but with substantially much less overhead.

A Fast-Acting Exposure Control System for Color Motion Picture Printing (1952)

An illuminating system in a contact-printer for color motion pictures is described. Light from a single lamp is divided into three beams which are independently filtered, controlled in intensity, and projected onto the printer aperture. Intensities of the red, green and blue components of the exposing light are measured continuously and photoelectrically and compared with reference voltages which are the analogs of the desired intensities and which are controlled by a perforated tape according to the predetermined requirements of each scene to be printed. Any errors between measured intensities and desired intensities, i.e., between photocell outputs and reference voltages, are amplified and applied to servomotors which rotate vanes in the respective beams until the correct intensities are established. A response time of the order of 1/50 sec has been achieved, and the intensity of the printing light is substantially independent of lamp current and age. A manual control on each of the reference voltages provides for emulsion-to-emulsion variations in print stock.
Variable stability of antibiotic‐resistance markers in <i>Bacillus cereus</i> UW85 in the soybean rhizosphere in the field (1993)

We compared the stability of antibiotic-resistance markers in strains derived from Bacillus cereus UW85 in culture media and in the soybean rhizosphere in a growth chamber and in the field. We studied two independent, spontaneous mutants resistant to neomycin, three independent, spontaneous mutants resistant to streptomycin, and strains carrying plasmid pBC16, which encodes tetracycline resistance. Antibiotic-resistance markers were maintained in populations of all UW85 derivatives in culture and in the rhizosphere of soybeans grown in soil in a growth chamber. In two field experiments, antibiotic resistance was substantially lost in rhizosphere populations of B. cereus as early as 14 or as late as 116 days after planting. To distinguish between death of the inoculated strain and loss of its marker, we tested populations of B. cereus for other phenotypes (orange pigmentation, plasmid-borne resistance to tetracycline, and biocontrol activity) that are typical of UW85-derivatives used as inoculum, but atypical of the indigenous populations of B. cereus, and these phenotypes were maintained in populations from which the marker was lost. In general, neomycin-resistance markers were maintained at a higher frequency than streptomycin-resistance markers, and maintenance of antibiotic-resistance markers varied with position on the root and with the year of the experiment. In a semi-defined medium, the UW85 derivatives grew at the same rate as the wild type at 28 degrees C, but most grew more slowly than the wild type at 16 degrees C, demonstrating that antibiotic resistance can affect fitness under some conditions. The results suggest that the stability of antibiotic-resistance markers should be assessed in the ecosystems in which they will be studied.
