A Physical Model to Predict Wear Sites Engendered by Flow-Assisted Corrosion (1999)

Flow-assisted corrosion (FAC), an aspect of erosion/corrosion (E/C), is a mechanism of piping degradation that causes a loss of material from the inside of the piping and then thinning of the wall. FAC damage is believed to be accelerated by a single- or two-phase mixture flowing within the piping. A physical model is presented that attempts to predict the distributions of sites of FAC wear within the fitting; this model includes the E/C and the three-dimensional single- or two-phase-flow models. Based on the calculated results, the impact of centrifugal and gravitational forces on liquid droplet behavior can be reasonably simulated. Appropriate indicators derived from the E/C model are used to predict the FAC locations. Compared with the plant measured results, the proposed model can precisely predict the distribution of wear sites. The FAC pattern dominated by the upstream fittings can also be determined. The satisfactory agreement reveals that the indicators provided by the current models can be used to reasonably predict the FAC locations and explain the complicated phenomenon of FAC wear occurring within the fittings.
Theoretical Analysis of Field Potentials in Anisotropic Ensembles of Neuronal Elements (1973)

Synchronous excitation of an ensemble of elements in the nervous system generates field potentials in and around the ensemble. Experimental analysis of these potentials can provide information about neuronal function.
A Pseudo-Synchronous Skew-Insensitive I/O Scheme for High Band width Memories (2005)

This paper describes a new skew-insensitive U0 scheme for high bandwidth processor-memory communication, which alleviates the interchip skew problem. High speed transmission up to 770Mbaud was obtained with multiphase clocks generated by phase-locked loop circuit. Interchip skew can be adjusted by the dual loop delay-locked loop based receiver. It is fabricated with 0.9pm CMOS process.
Anomaly Detection using a Clustering Technique (2012)

Computer networks are usually vulnerable to attacks by any unauthorized person trying to misuse the resources.. Hence they need to be protected against such attacks by Intrusion Detection Systems (IDS). The traditional prevention techniques such as user authentication, data encryption, avoidance of programming errors, and firewalls are only used as the first line of defense. But, if a password is weak and is compromised, user authentication cannot prevent unauthorized use. Similarly, firewalls are vulnerable to errors in configuration and sometimes have ambiguous/undefined security policies. They fail to protect against malicious mobile code, insider attacks and unsecured modems. Therefore, intrusion detection is required as an additional wall for protecting systems.
Guidelines for the grading of tinnitus severity: the results of a working group commissioned by the British Association of Otolaryngologists, Head and Neck Surgeons, 1999 (2001)

Tinnitus is a common experience with up to one third of the adult population experiencing it at some time in their life. Less than 1% of the adult population have tinnitus of sufficient severity to affect their quality of life seriously (although up to 8% may seek medical advice about it). Much of the severity of tinnitus relates to the individuals' psychological response to the abnormal tinnitus signal. The prevalence of tinnitus increases in association with high frequency hearing loss. There is, unfortunately, no diagnostic test that either confirms the presence of tinnitus or its severity. Currently there is no satisfactory severity grading system. A five-point severity grading scheme is therefore proposed and the entry criteria detailed. The five severity points are: slight, mild, moderate, severe and catastrophic. Categorization as 'severe' or 'catastrophic' should be, by epidemiological definition, very rare. General guidance, theory and evidential support are contained within.
Formalization of UML statechart models using Concurrent Regular Expressions (2004)

The Unified Modeling Language (UML) is widely used in the software development process for specification of system based on the object-oriented paradigm. Thought the current version of UML is semi-formal, it is difficult to determine whether the model is consistent, unambiguous, or complete. This paper proposes the transformation rules for formalizing UML statechart diagrams. The target language for the transformation is Concurrent Regular Expressions (CREs) which are extensions of regular expression. The transformation result will be represented in mathematical form and suitable for applying verification. We also show that this formalization can be used to check the simple inconsistency of the system.

Attenuated CPK Following Carbohydrate/protein Intervention Improves Subsequent Performance (2005)

Attenuated post-exercise CPK levels have been observed in athletes consuming carbohydrate/protein beverages (CHO+P) during and following endurance exercise versus those using carbohydrate-only (CHO) beverages. Purpose The purpose of this study was to determine if cyclists who experienced large attenuations in CPK (indicating less muscle damage) following CHO+P administration performed better during subsequent exercise than those with small effects from the beverage treatment. Methods Fourteen recreationally competitive male cyclists (VO2peak=53.5±9.5 ml/kg/min) rode a cycle ergometer at 75% of VO2peak until volitional exhaustion. This ride was designed to produce glycogen depletion and fatigue, in order to assess the effectiveness of CHO+P beverages on muscle damage and subsequent performance. Using a counter balanced, double-blind design, subjects consumed 1.8ml/kgBW of CHO or CHO+P every 15 minutes of exercise, and 10 ml/kgBW of the same beverage within 30 minutes of exercise completion. Fifteen hours later, subjects had blood samples taken to assess plasma CPK levels, and then performed a second ride to exhaustion at 85% of VO2peak. Results Post-exercise CPK levels were significantly lower (p<.05) following the CHO+P trial compared to the CHO trial. A natural break was evident in the distribution of between-trial differences in CPK among cyclists. The majority of subjects (n=9) experienced large attenuations in CPK during the CHO+P trial versus the CHO trial. This “attenuated response” group (AR) had a mean CPK difference (CHO+P trial minus CHO trial) of 974.9±589.7 U/L (range=453–2326 U/L). The remaining five cyclists were “non-responders” (NR; mean difference=−10.0±31.6 U/L, range=−180–80 U/L). To determine whether differences in post-exercise CPK responses influenced subsequent cycling endurance, performance was compared between the two groups during the second ride using a dependent t-test. The difference in time to exhaustion (CHO+P trial minus CHO trial) was significantly larger (p<.05) in the AR group (16.0±10.2 min) than the NR group (5.3±4.4 min). Conclusion Post-exercise muscle damage was notably attenuated by CHO+P beverage administration in the majority of cyclists. Cyclists who experienced large reductions in CPK following CHO+P treatments performed significantly better during subsequent exercise than non-responders.
Risk terrain modeling predicts child maltreatment (2016)

As indicated by research on the long-term effects of adverse childhood experiences (ACEs), maltreatment has far-reaching consequences for affected children. Effective prevention measures have been elusive, partly due to difficulty in identifying vulnerable children before they are harmed. This study employs Risk Terrain Modeling (RTM), an analysis of the cumulative effect of environmental factors thought to be conducive for child maltreatment, to create a highly accurate prediction model for future substantiated child maltreatment cases in the City of Fort Worth, Texas. The model is superior to commonly used hotspot predictions and more beneficial in aiding prevention efforts in a number of ways: 1) it identifies the highest risk areas for future instances of child maltreatment with improved precision and accuracy; 2) it aids the prioritization of risk-mitigating efforts by informing about the relative importance of the most significant contributing risk factors; 3) since predictions are modeled as a function of easily obtainable data, practitioners do not have to undergo the difficult process of obtaining official child maltreatment data to apply it; 4) the inclusion of a multitude of environmental risk factors creates a more robust model with higher predictive validity; and, 5) the model does not rely on a retrospective examination of past instances of child maltreatment, but adapts predictions to changing environmental conditions. The present study introduces and examines the predictive power of this new tool to aid prevention efforts seeking to improve the safety, health, and wellbeing of vulnerable children.
Orofacial motor control impairment in Parkinson's disease (1987)

Motor impairments in lip, jaw, and tongue muscles in patients with idiopathic Parkinson's disease (PD) were quantified. These orofacial muscle groups are nonuniformly endowed with muscle afferents, thus permitting evaluation of the hypothesis that certain PD motor symptoms are due to aberrations in muscle afferent function. Tongue muscles, devoid of stretch reflexes, were most impaired, while jaw-closing muscles, with numerous spindles and a monosynaptic stretch reflex, manifested the least impairment. Seemingly, PD motor impairments are independent of fusimotor or muscle afferent dysfunctions.
Semantics and KPIs to improve partner selection for small series production (2012)

This paper describes an on-going research and development activity to implement a semantic-based Partner Search service for supporting companies in a supply chain network configuration as one of the key elements of a comprehensive architecture with the aim of supporting collaborative design, planning and manufacturing for highly customised goods. The Partner Search service is the module in charge of managing and improving the manufacturer's knowledge about its, even potential, supply chains. This service, therefore, has to support the manufacturer in managing information, based on capabilities and performance, about past and present partners, as well as in identifying new potential suppliers. The service is useful especially to develop effective partnerships when producing small batches, where it is necessary to have a reduced and easily manageable supply base.
Effect of percolation on free‐radical polymerization of acrylamide in inverse microemulsion (1994)

Abstract The kinetics of free‐radical polymerization of acrylamide initiated by dibenzoyl peroxide in non‐percolating and percolating inverse microemulsions (toluene/sodium bis(2‐ethylhexyl) sulfosuccinate/water/acrylamide) and the properties of polyacrylamide particles formed from these inverse microemulsions were investigated. The acrylamide polymerization rate and polyacrylamide number‐average molecular mass depend on the acrylamide concentration in the dispersed phase of the inverse microemulsion. For non‐percolating inverse microemulsions these dependecies are described by the equation where x and y have the values of 1.8 and 1.4 respectively, while for percolating inverse microemulsions the respective values of x and y are 1.1 and 0.4. Data on polymer particle size and number‐average molecular mass of polyacrylamide in polymer particles were used for calculation of the average number of polymer chains in polymer particles for non‐percolating (approximately one chain per particle) and for percolating (more than two chains per particle) inverse microemulsions. The spin probe (potassium nitrosodisulfonate, Fremy's salt) correlation time τ c expressing the spin probe mobility in water‐swollen polymer particles and in polyacrylamide water solution pointed to the ‘collapsed’ state of polyacrylamide chains in polymer particles in both kinds of inverse microemulsions. Besides the dependencies of polyacrylamide polymerization rate and of number‐average molecular mass of polyacrylamide on the acrylamide concentration in inverse microemulsions, the dependence of T 50G values, characterizing the spin probe mobility in polymer particles of inverse microemulsions as a function of polyacrylamide concentration in the polymer particles, is different for nonpercolating and percolating inverse microemulsions.
Efficient implementation of perceptual postfilter for CELP coding of speech (2002)

An efficient method to implement the perceptual posterfilter for the suppression of coding noise in CELP-coded speech is proposed. The method is based on approximating the response of an all-pole filter to the response of the pole-zero form postfilter via cepstrum processing. This all-pole postfilter can then be implemented more efficiently than the pole-zero postfilter with less computation and filter memory.

Raman spectroscopy of sol–gel ultrathin films enhanced by surface plasmon polaritons (2000)

We present experimental results of a Kretschmann-prism coupler method used in Raman scattering experiments with ultrathin (few nanometers) TiO2 sol–gel films deposited on a metallic silver layer characterized by surface plasmon resonance (SPR) experiments. In this article, we describe a new optical device as an application of SPR properties and coupled with a micro-Raman scattering setup. The enhancement factor (150) of the Raman intensity in comparison to the classical way allows us to determine the critical thin films structure. Optical results are then discussed and compared to transmission electron microscopy.

Determination of lignans in Wuweizi by using magnetic bar microextraction and <scp>HPLC</scp> (2013)

In this paper, a magnetic bar microextraction was developed to extract schisandrin A, schisantherin A, and deoxyschizandrin from Wuweizi. The analytes were determined by HPLC. A stainless-steel wire was inserted into the hollow of the hollow fiber to make the magnetic bar. The bar can be used to stir the extraction system and extract the analytes, and was isolated from the extract system by magnetic force. Several experimental parameters, including type and volume of extraction solvent, the number of magnetic bars, extraction temperature and time, stirring speed and NaCl concentration were investigated and optimized. The LODs for schisandrin A, schisantherin A, and deoxyschizandrin were 0.14, 0.06, and 0.10 g/mL, respectively. The recoveries were in the range of 70.90-106.67% and the RSDs were < 8.84%. Compared with ultrasound-assisted and Soxhlet extraction, when the present method was applied, the extraction time was shorter, the sample amount was smaller, and the consumption of organic solvent was lower.
Properties of tungsten silicide film on polycrystalline silicon (1981)

Tungsten silicide on polycrystalline Si becomes increasingly important as interconnections and gate electrodes for metal-oxide-semiconductor field-effect transistor(MOSFET) integrated circuits. Annealing behaviors of coevaporatd tungsten silicide on P-doped poly-Si are studied by x-ray diffraction, He+-backscattering, transmission electron microscopy (TEM), and secondary ion mass spectroscopy (SIMS). High-temperature annealing of silicides results in crystallization and homogenization of tungsten silicide as well as phosphorus out-diffusion from the poly-Si. Their effect on device fabrication is also discussed.

A DESIGN OF THREE-DIMENSIONAL SPATIAL DATA MODEL AND ITS DATA STRUCTURE IN GEOLOGICAL EXPLORATION ENGINEERING (1999)

The key to develop 3-D GISs is the study on 3-D data model and data structure. Some of the data models and data structures have been presented by scholars. Because of the complexity of 3-D spatial phenomenon, there are no perfect data structures that can describe all spatial entities. Every data structure has its own advantages and disadvantages. It is difficult to design a single data structure to meet different needs. The important subject in the3-D data models is developing a data model that has integrated vector and raster data structures. A special 3-D spatial data model based on distributing features of spatial entities should be designed. We took the geological exploration engineering as the research background and designed an integrated data model whose data structures integrats vector and raster data byadopting object-oriented technique. Research achievements are presented in this paper.
Efficient Overall Water‐Splitting Electrocatalysis Using Lepidocrocite VOOH Hollow Nanospheres (2016)

Herein we report the control synthesis of lepidocrocite VOOH hollow nanospheres and further their applications in electrocatalytic water splitting for the first time. By tuning the surface area of the nanospheres, the optimal performance can be achieved with low overpotentials of 270 mV for the oxygen evolution reaction (OER) and 164 mV for the hydrogen evolution reaction (HER) at 10 mA cm<sup>-2</sup> in 1 m KOH, respectively. Furthermore, when used as both the anode and cathode for overall water splitting, a low cell voltage of 1.62 V is required to reach the current density of 10 mA cm<sup>-2</sup> , making the VOOH hollow nanospheres an efficient alternative to water splitting.
hRLX-1. In vitro response of human and pig myometrium. (1995)

This result shows that h RLX-1 peptide does not appear to be an inhibitor of human myometrial activity and that although the pig myometrial relaxin receptor does not appear to distinguish between the two human relaxins, the human relaxin receptor might. Thus, the control of spontaneous myometrial activity during pregnancy in the human appears to be different from that in other species.
Mutants of Escherichia coli Initiator tRNA Defective in Initiation (1995)

We describe the effects of overproduction of methionyl-tRNA transformylase and initiation factors IF2 and IF3 on the activity, in vivo, of initiator tRNA mutants defective at specific steps of the initiation process in protein synthesis. The activity of the U35A36/G72 and U35A36/G72G73 mutants, which are defective in formylation, was increased by overproduction of methionyl-tRNA transformylase. In contrast, the activity of the C30:G40/U35A36 mutant, which is formylated normally but is defective in binding to the ribosomal P site, was not increased. Overproduction of IF2 had a strong stimulatory effect on the activity of virtually all the mutants carrying the U35A36 anticodon sequence change, including the U35A36, U35A36/G72, U35A36/G72G73, and the C30:G40/U35A36 mutants. In cells overproducing IF2, the amount of protein made by translation of a mutant mRNA, which uses the U35A36 mutant initiator tRNA, is severalfold higher than that made by translation of a wild type mRNA. We discuss the possible implications of this result on overproduction of proteins and on the order of assembly of the 30 S ribosome.mRNA.fMet-tRNA initiation complex in Escherichia coli. Over-production of IF3 did not affect the initiator activity of any of the tRNA mutants studied.
Active refinement of clone anomaly reports (2012)

Software clones have been widely studied in the recent literature and shown useful for finding bugs because inconsistent changes among clones in a clone group may indicate potential bugs. However, many inconsistent clone groups are not real bugs (true positives). The excessive number of false positives could easily impede broad adoption of clone-based bug detection approaches. In this work, we aim to improve the usability of clone-based bug detection tools by increasing the rate of true positives found when a developer analyzes anomaly reports. Our idea is to control the number of anomaly reports a user can see at a time and actively incorporate incremental user feedback to continually refine the anomaly reports. Our system first presents top few anomaly reports from the list of reports generated by a tool in its default ordering. Users then either accept or reject each of the reports. Based on the feedback, our system automatically and iteratively refines a classification model for anomalies and re-sorts the rest of the reports. Our goal is to present the true positives to the users earlier than the default ordering. The rationale of the idea is based on our observation that false positives among the inconsistent clone groups could share common features (in terms of code structure, programming patterns, etc.), and these features can be learned from the incremental user feedback. We evaluate our refinement process on three sets of clone-based anomaly reports from three large real programs: the Linux Kernel (C), Eclipse, and ArgoUML (Java), extracted by a clone-based anomaly detection tool. The results show that compared to the original ordering of bug reports, we can improve the rate of true positives found (i.e., true positives are found faster) by 11%, 87%, and 86% for Linux kernel, Eclipse, and ArgoUML, respectively.
