EXPERIMENTAL STUDY ON RESTORING FORCE CHARACTERISTICS OF SHEAR YIELDING THIN STEEL PLATE ELEMENTS (1997)

Steel shear wall and link of eccentric braces are used as shear yielding seismic elements. However, there was little knowlege concerning shear force-shear deformation characteristics of thin steel plates up to their collapse state, and a series of shear loading tests of thin steel plate surrounded by vertical and horizontal stiffeners, were conducted within the parameters of both steel materials and width-to-thickness ratios. On the basis of the test results, three models of restoring force characteristics and some practical recommendations for designing the seismic elements that have stable behavior are proposed.
Measuring interface for an ECT System (2011)

This paper describes the measuring interface to be included in an automated microcomputer based Eddy Current Testing (ECT) system developed to characterize structural flaws inside electrically conducting nonmagnetic plates. The principle of operation is based on the measurement of the output voltages of two sensing coils. A description of the implemented prototype using two different types of probes including the digital signal processing used to overcome the signal degradation is presented. The application of a 2D Finite Element Method (FEM) allows to preview the range of the resulting output voltages in the detection coils and also the excitation current amplitude necessary to obtain a given signal to noise ratio. The experimental results obtained with the two probes are presented and one may conclude by inspection that the quality of the obtained data and the amount of information required for future structural defects characterization depend greatly on the probe geometry.

Urease Inhibitory Activities of some Commonly Consumed Herbal Medicines. (2015)

Urease enzyme has a crucial role in the persistent habitation of Helicobacter pylori (H. pylori) that induces gastrointestinal diseases, in particular gastritis, duodenal, peptic ulcer, and gastric cancer. Plants have long been utilized as the biggest source of substances with medicinal properties from natural origin and therefore result in less toxicity and adverse side effects upon usage. 15 medicinal plant extracts were examined against Jack bean urease activity by Berthelot reaction. Each herb was extracted using 80% aqueous methanol. The more effective extracts were further tested and their IC50 values were determined. Three plant extracts including Ginkgo biloba, Rhus coriaria, and Matricaria inodora were found to be the most effective ones with IC50 values of 36.17, 80.29, and 100.6 μg/mL, respectively.
A Novel Predictive Technique for the MHC Class II Peptide-Binding Interaction (2003)

Antigenic peptide is presented to a T-cell receptor through the formation of a stable complex with a Major Histocompatibility Complex (MHC) molecule. Various predictive algorithms have been developed to estimate a peptide's capacity to form a stable complex with a given MHC Class II allele, a technique integral to the strategy of vaccine design. These have previously incorporated such computational techniques as quantitative matrices and neural networks. We have developed a novel predictive technique that uses molecular modeling of predetermined crystal structures to estimate the stability of an MHC Class II peptide complex. This is the 1st structure-based technique, as previous methods have been based on binding data. ROC curves are used to quantify the accuracy of the molecular modeling technique. The novel predictive technique is found to be comparable with the best predictive software currently available.
Einleitung (2004)

Die vorliegende Arbeit befasst sich mit einem Ausschnitt aus dem weiten Problemfeld der Entstehung von Einkommensdifferenzen zwischen Frauen und Männern. Sie will einen Beitrag leisten, die Mechanismen ihres Zustandekommens zu erklären. Im Mittelpunkt dieser Untersuchung befinden sich die abhängig Beschäftigten, die betriebliche Ebene und das Grundentgelt. 1 Ausgangspunkt sind die nach wie vor deutlichen Entgeltdifferenzen zwischen weiblichen und männlichen Beschäftigten, die überall zu Ungunsten der Frauen ausfallen, und die nicht nur in der Bundesrepublik Deutschland, sondern in allen EU-Mitgliedstaaten festzustellen sind.2
Hexachlorocyclotriphosphazene (HCCP)-Mediated Direct Formation of Thioethers and Ethers from Quinazolin-4(3H)-ones (2013)

A hexachlorocyclotriphosphazene (HCCP)-mediated direct formation of quinazoline (thio)ethers from quinazolin-4(3H)-ones has been developed. Treatment of quinazolin-4(3H)-ones with HCCP, diisopropylethylamine (DIPEA), and thiophenols resulted in formation of the corresponding 4-arylthioquinazoline derivatives in moderate to excellent yields. This method has also been utilized to prepare 4-aryloxyquinazoline and 4-alkoxyquinazoline derivatives using phenols and sodium alkoxides as the nucleophiles.
Design of prototype expert system for transliterating Arabic-to-Roman words (2006)

Transliteration of Arabic words into their equivalent Roman words is vital for the proper pronunciation of the origin words. Traditionally, it has been done manually through the use of language interpreter/linguists. Presenting written Arabic words and vowelising each letter can be a difficult task, especially for beginners to the Arabic language. Hence, the use of rule-based system as a practical realization of expert system has been attempted to reduce some vowelisation problems. Coding has been done using Visual Basic through 'if-else' code sequences. A data set comprising of coded Arabic letter representations has been used as input. Character code mappings between the 8-bit Arabic character codes and the more 'conventional' 7-bit ASCII have been performed. The problem of rendering Arabic letters has been solved via the use of WinXP Arabic as the platform for the VB program. Next, transliteration rules are compiled and used as reference guide to avoid ambiguous Arabic-Roman transliteration. Simulation results showed 93.75% accuracy on training binary input patterns of Arabic words to match their Roman equivalents. The results explain that knowledge can be extracted in the form of numerical data set representing salient features of the transliteration domain. The extracted knowledge can be further utilised to form the knowledge base of a future expert system section.
FSML: Fusion Simulation Markup Language for interoperability of data and analysis tools (2005)

As the fusion community becomes more interconnected and problems become more complex, very close collaborative efforts are expected. This requires internetworking various codes, comparing solutions from multiple solvers, and sharing of data and data analysis tools. However, the data formats and data analysis tools used in fusion and plasma simulations are highly heterogeneous. Imposing one standard data format and one type of tools is unrealistic due to historical and practical reasons. In this paper, we propose to create the Fusion Simulation Markup Language or FSML - an XML based system for describing and accessing fusion and plasma physics simulation data of various formats used in the community. The system consists of syntactic and semantic metadata organized in specialized XML schemas and APIs written for accessing data from major data analysis and visualization tools. We present the preliminary results in formulation the FSML schema and APIs in AVS/Express modules, and demonstrate their application for two large three-dimension fusion simulation codes M3D and NIMROD. The results show that FSML schema and the set of tools developed provide a strong initial momentum and technology for the community effort to enhance data exchange and interoperability of analysis tools.
A construction method and data migration strategy for hybrid cloud storage (2015)

With more and more enterprises constructed their own private cloud storage platforms, certain limitations and challenges come for small and medium enterprises. So hybrid cloud storage is imperative with public cloud as a complement. In this paper, we propose a fast and efficient method to build a hybrid cloud storage framework: base on open source software OpenStack Swift to build the private cloud storage, use Baidu Object Storage as the public cloud provider, and do a second development of Cyberduck as the cloud storage client. This framework can realize the seamless integration of private and public cloud. To tackle the data migration problem in hybrid cloud storage, we present a part-migration-part-retention self-adaptive periodic migration strategy, and the specific implementation of migration process is given. The strategy not only improve the utilization rate of local cloud storage, but also make reasonable use of public cloud storage.
Preparation and spectral properties of imidazo- and triazoloquinolines with angular ring fusion (1988)

The imidazo- and triazolo[4,5- f ]quinolines ( Va, Vb ) and imidazo- and triazolo[4,5- h ]quinolines ( Xa, Xb ) have been synthetized by the Gould-Jacobs reaction starting from the quinolinecarboxylic acids II and VII prepared by base-catalyzed hydrolysis of the esters I and VI , resp. The decarboxylation of the acids II and VII gives the quinolones III and VIII , resp., which are aromatized to the corresponding chloroquinolines IV and IX . The latter compounds give the azoloquinolines V and X on catalytic reduction. The structure of the condensed heterocyclic compounds with angular ring fusion has been proved by 1 H and 13 C NMR, IR, UV, and mass spectra.
Screening An alpha-glucosidase Inhibitor from A Phage-displayed Peptide Library. (2001)

A phage-displayed peptide library was biopanned with Aspergillus niger glucoamylase. Three specifically binding phage clones (GB-1, GB-2 and GB-3) were identified after three cycles of screening and amplification. All three peptides contained a disulfide bridge, and the impairment of disulfide bond greatly lowered the binding activity. One peptide, cyclic KCHFEECLAY, representing the N-terminal 10 amino acid residues from GB-1, competitively inhibited A. niger glucoamylase (K(I) 0.2 mmol/L) as well as rat intestinal alpha-glucosidase (KI 1.4 mmol/L).
A scalable watermarking scheme for the scalable audio coder (2005)

In this paper, we describe a scalable (i.e., lossy-to-lossless) watermarking scheme which overcomes the problem of non-invertible distortion introduced by the watermark signal. The scheme is based on a standardized scalable audio coder (R.S. Yu, et al, 2004) -as a result, the embedded watermark inherits the scalability of the audio coder. We elaborate how the scalability can be used to realize the recovery of the lossless audio signal after watermark embedding. The experimental results demonstrate the validity of the proposed watermarking scheme in terms of robustness, data expansion and perceptual quality.
Peptide nucleic acids: structure, properties, applications, strategies and practice of chemical synthesis (2002)

The information on the structure and properties of peptide nucleic acids (PNA) is generalised. The use of PNA oligomers in biomolecular studies and biotechnology is exemplified. The published data on the most important methods for the chemical synthesis of PNA oligomers with the main emphasis on the efficiency of condensation reactions are considered. The methods for PNA synthesis are systematised; their advantages and disadvantages are discussed. Some recommendations for optimisation of the condensation procedure and synthesis of PNA are presented. The bibliography includes 153 references.
Anti-Inflammatory and Anti-Nociceptive Activity of Disodium Glycyrrhetinic Acid Hemiphthalate (1996)

The anti-inflammatory and anti-nociceptive effects of disodium glycyrrhetinic acid hemiphthalate (glycyrrhetinic acid 3 beta-O-hemiphthalate sodium) after parenteral administration were determined in several animal models. Disodium glycyrrhetinic acid hemiphthalate (GAP) significantly inhibited the rat paw edema induced by carrageenin (ID50 = 21.37 mg/kg), and mice writhing responses caused by acetic acid (ID50 = 9.12 mg/kg). The potency of disodium glycyrrhetinic acid hemiphthalate was about 13.05 times higher than acetylsalicylic acid in inhibiting rat paw edema and 12.84 times higher in inhibiting abdominal constrictions in mice.
Numerical Simulations of the ECR Heating With Waves of Different Frequency in Electron Cyclotron Resonance Ion Sources (2008)

The improvement of highly charged ion production with the use of two-frequency heating (TFH) in electron cyclotron resonance ion sources (ECRISs) was observed for the first time already in 1994, but the process has not been explained in details yet. The increase of the ionization rate because of the presence of two resonance surfaces instead of one is clear but not the relation between the two frequencies and the relative weight in terms of power. A series of numerical simulations about the heating process in ECR plasmas has been carried out at INFN-LNS, based on a single particle approach. They allow one to give a reasonable explanation of the TFH of the plasma electrons in terms of the microwave field distribution over the resonance surface, which changes with the excited mode, i.e., with the frequency. By analyzing the results, some considerations about the phase relationship between the electron's gyromotion and the electromagnetic wave can be done, taking into account the stochastic heating theory of ECR plasmas. The phase difference between the two waves in this case is shown to play a role. Finally, the analysis of the simulations' output will give the possibility to explain a great deal of experimental results concerning the multifrequency heating of plasmas in ECRIS.

Increasing ion selective electrodes performance using neural networks (2003)

This paper reports the implementation of a neural processing structure as a component of an intelligent measuring system that uses ion selective electrodes (ISEs) as sensing elements of heavy metal ions (Pb/sup +2/, Cd/sup +2/) concentration. The neural network (NN), designed and implemented to reduce errors due to ion interference and to pH and temperature variations, is of the multiple-input multiple-output Multilayer Perception (MLP-NN) type The NN is a component of a virtual instrument that includes a PC laptop, a PCMCI data acquisition board with associated conditioning circuits and the specific ISE sensors. A practical approach concerning the optimal neural processing solution (number of NN structures, number of neurons, neuron transfer functions) to increase the performance of low cost ISEs is presented. Results are presented to evaluate the performance of the NN intelligent ISE system and to discuss the possibility of transferring the acquisition and processing task to a low cost acquisition and control unit such as a microcontroller.
Chemical peels. (2004)

With so many new peel preparations on the market today, the dermatologist must ask himself basic questions concerning the products. The most important question is directed to the medical literature rather than the advertising or marketing campaign so common among market-driven cosmetic products. Since all peeling agents--superficial, medium depth and deep--are derived from basic chemicals known to cause exfoliation, destruction and/or inflammation of skin in a controlled manner, the clinician must ask what is new and better about the product. Peeling agents, regardless of their proprietary new name, fall into chemical families. The clinical evaluation of these generic agents is well documented in our literature as to efficacy, technical care and safety. In addition, combinations of peeling agents have been presented in the dermatologic cosmetic literature with scientific clinical trials and histology. These include: 1) The Gordon-Baker phenol peel; 2) Combination medium depth peeling; 3) Glycolic acid formulations. It is the responsibility of the dermatologic surgeon to be in control of his chemicals and his products. It is thus necessary for him to understand all the products and the peel formulation and be sure it has undergone the test of objective scientific study with clear clinical evaluations and histology. Only then will we truly know the effectiveness of the agents we are using for exfoliating and resurfacing.
Price Fluctuations and the Use of Bitcoin: An Empirical Inquiry (2015)

Over recent years, interest has been growing in Bitcoin, an innovation that has the potential to play an important role in e-commerce and beyond. The aim of our paper is to provide a comprehensive empirical study of the payment and investment features of Bitcoin, and their implications for the conduct of e-commerce. Since network externality theory suggests that the value of a network and its take-up are interlinked, we investigate both adoption and price formation. We discover that its returns are driven primarily by Bitcoin’s popularity, the sentiment expressed in newspaper reports on cryptocurrency, and total number of transactions. The paper also reports on the first global survey of merchants who have adopted this technology, and we model the share of sales paid for with this alternative currency, using both ordinary and Tobit regressions. Our analysis examines how country-, customer-, and company-specific characteristics interact with the proportion of sales attributed to Bitcoin. We find that company features, use of other payment methods, customers’ knowledge about Bitcoin, and the size of both the official and unofficial economy are significant determinants. The results will be of interest to traders who seek to understand factors driving prices and will help to inform vendors as to the most favorable circumstances for adopting the currency for online transactions.
Functional wound dressing materials with highly tunable drug release properties (2015)

Tuning of diclofenac release was achieved through incorporation into four different wound dressing materials. Proposed specific material-drug combinations could greatly improve efficiency in treatment of different wound types.
High data rate transmission with 64-DAPSK over fading channel (2004)

In this paper a simplified differential amplitude demodulation scheme is proposed for 64-DAPSK (differential amplitude and phase shift keying), which needs less quantity of decision thresholds compared with the conventional schemes. The arithmetic mean threshold (AlMT) scheme is proposed and analyzed with the simplified system in AWGN and flat Rayleigh fading channels. By these proposed schemes, system complexity is reduced considerably, but no performance degradation occurs. In the case of channel coding, the concatenated code consisting of an inner convolutional code and an outer Reed-Solomon code can be applied to 64-DAPSK. Compared with coherent 64-QAM system which employs pilot symbols for channel estimation, 64- DAPSK can achieve the performance close to or even better than that of the former by utilizing the additional redundancy for outer coding, provided that the channel SNR is high enough.
[Isolation and characteristics of ligand specificity of VLA-1 integrin from human smooth muscles]. (1991)

Using affinity chromatography with immobilized monoclonal antibodies to the beta 1-subunit of human integrin, a total integrin fraction (subfamily beta 1) was isolated from the detergent extract of human smooth muscle (uterus). Immunoprecipitation and immunoblotting with specific antibodies revealed integrins VLA-1 and VLA-5. The former was isolated in a homogeneous state by chromatography on immobilized type I collagen in the presence of 1 mM Mn2+. The pure receptor yield was 2-4 mg per 400 g of smooth muscle tissue. Analysis of substrate specificity of VLA-1 in the liposome test revealed that this integrin possesses a broad spectrum of ligand specificity and can interact via a Ca2+, Mg(2+)-dependent mechanism with interstitial collagens of I, II and III types and with basal membrane proteins (type IV collagen and laminin). VLA-1 does not interact with fibronectin, thrombospondin or albumin. Denaturation of type I collagen decreases the liposome binding 5-7-fold. The peptide Gly-Arg-Gly-Asp-Ser-Pro added to the incubation mixture does not inhibit the liposome interaction with incorporated VLA-1 integrin, type I collagen and laminin.
Filling Holes in Triangular Meshes in Engineering (2012)

In this paper, a novel hole-filling algorithm for triangular meshes is proposed. Firstly, the hole is triangulated into a set of new triangles using modified principle of minimum angle. Then the initial patching mesh is refined according to the density of vertices on boundary edges. Finally, the patching mesh is optimized via the bilateral filter to recover missed features. Experimental results demonstrate that the proposed algorithm fills complex holes robustly, and preserves geometric features to a certain extent as well. The resulted meshes are of good quality for engineering.
Barriers to health care for people with hearing loss: a review of the literature. (2009)

Deaf individuals face many barriers when trying to access health care. The reasons why barriers are encountered, difficulties met as a result of the barriers, and ways that health professionals and others working with deaf people can overcome obstacles are included in this review of the literature. A brief summary of Deaf culture and history gives background information to better understand the problems. Misunderstandings by d/Deaf patients and hearing health professionals are addressed, as well as issues related to medical interpreters. This paper aims to make health professionals more aware of the needs and cultural differences that must be considered when providing care to the d/Deaf population.
