Removable partial denture design considerations where periodontally compromised teeth exist. (1997)

Restoration of a periodontally compromised dental arch with a removable partial denture may require one or more design modifications. Multiple rests ensure that adequate vertical support remains in the event primary abutment teeth are lost. An open or closed base can be strategically placed in the maxillary major connector to facilitate the replacement of subsequently lost teeth. The location of finish lines can be modified to provide a smoother resin-to-metal transition when posterior teeth are lost. Wire direct retainers that provide more physiologically acceptable clasping of compromised teeth and that are easily adjusted and added to the prosthesis should be considered.
Chemical-sensitive field-effect transistors (1983)

The integration of various types of semiconductor devices with particular electrochemically active thin films makes possible a new generation of integrated-circuit chemical microtransducers which have many important (and unique) advantages over their conventional antecedents, including small size, robust solid-state nature and the potential for low-cost mass-fabrication; attributes which are particularly appropriate for biomedical usage. The prime semiconductor device for such applications is the MIS transistor. first modified into an ion-sensitive (chemical-sensitive) field-effect transistor (ISFET, ChemFET) in 1970. The paper reviews the development of ChemFET devices since their inception, and describes the important aspects of their theory, structure and design with particular emphasis on the practical features of device operation. As an illustrative example, a novel triple-function chemical-sensing IC for the simultaneous measurement of K+, H+ and Ca2+ in aqueous solutions is described.
The Influence of Drawing Parameters on the Mechanical Properties of Two Beta-titanium Alloys (1983)

The total cold reduction and reduction per pass used during the drawing of fine wires affected the mechanical properties of two beta-titanium alloys. Both Ti-11.5Mo-6Zr-4.5Sn and Ti-13V-llCr-3Al showed increased yield strengths and low moduli of elasticity, which resulted in wires appropriate for orthodontic application.
Real-time detection of illegally parked vehicles using 1-D transformation (2007)

With decreasing costs of high quality surveillance systems, human activity detection and tracking has become increasingly practical. Accordingly, automated systems have been designed for numerous detection tasks, but the task of detecting illegally parked vehicles has been left largely to the human operators of surveillance systems. We propose a methodology for detecting this event in realtime by applying a novel image projection that reduces the dimensionality of the image data and thus reduces the computational complexity of the segmentation and tracking processes. After event detection, we invert the transformation to recover the original appearance of the vehicle and to allow for further processing that may require the two dimensional data. The proposed algorithm is able to successfully recognize illegally parked vehicles in real-time in the i-LIDS bag and vehicle detection challenge datasets.
Cross Talk among the Glycoproteins Involved in Herpes Simplex Virus Entry and Fusion: the Interaction between gB and gH/gL Does Not Necessarily Require gD (2009)

The gD, gB, and gH/gL glycoprotein quartet constitutes the basic apparatus for herpes simplex virus (HSV) entry into the cell and fusion. gD serves as a receptor binding glycoprotein and trigger of fusion. The conserved gB and gH/gL execute fusion. Central to understanding HSV entry/fusion has become the dissection of how the four glycoproteins engage in cross talk. While the independent interactions of gD with gB and gD with gH/gL have been documented, less is known of the interaction of gB with gH/gL. So far, this interaction has been detected only in the presence of gD by means of a split green fluorescent protein complementation assay. Here, we show that gB interacts with gH/gL in the absence of gD. The gB-gH/gL complex was best detected with a form of gB in which the endocytosis and phosphorylation motif have been deleted; this form of gB persists in the membranes of the exocytic pathway and is not endocytosed. The gB-gH/gL interaction was detected both in whole transfected cells by means of a split yellow fluorescent protein complementation assay and, biochemically, by a pull-down assay. Results with a panel of chimeric forms of gB, in which portions of the glycoprotein bracketed by consecutive cysteines were replaced with the corresponding portions from human herpesvirus 8 gB, favor the view that gB carries multiple sites for interaction with gH/gL, and one of these sites is located in the pleckstrin-like domain 1 carrying the bipartite fusion loop.
RFID-based real-time smart waste management system (2007)

In an environmental context, the use of RFID (radio frequency identification) and load cell sensor technology can be employed for not only bringing down waste management costs, but also to facilitate automating and streamlining waste (e.g., garbage, recycling, and green) identification and weight measurement processes for designing smart waste management systems. In this paper, we outline a RFID and sensor model for designing a system in real-time waste management. An application of the architecture is described in the area of RFID and sensor based automatic waste identity, weight, and stolen bins identification system (WIWSBIS).
Individualized Compensating Filters and Dose Optimization in Pelvic Irradiation (1973)

A method is presented for design and construction of individualized, shaped, tapered split-field blocks for external beam use in combined brachytherapy and teletherapy of pelvic malignancies. Coronal plane implant calculations and a block-making device are needed. The physician specifies the total split-field dose and the radiation to supplement areas of insufficient brachytherapy. A hot wire cuts styrofoam slabs of appropriate thickness to conform to isodose zones from implant calculations. Cerrobend® alloy, the attenuating material, is cast into the spaces and the block is positioned in accordance with portal and implant radiographs. Thermoluminescent dosimetry confirms the method.
고장력 볼트 기둥-기초 연결부의 강도특성에 관한 해석적 연구 (2016)

고장력 볼트를 적용한 원형단면 콘크리트 충전 강재 기둥-기초 연결부의 합리적인 설계범위를 제안하기 위하여 축하중과 수평하중을 동시에 받는 기둥-기초 연결부의 전반적인 구조적 거동과 설계변수에 따른 거동특성을 상용 유한요소해석 프로그램인 ABAQUS를 이용하여 해석적으로 검토하였다. 이를 위해 앵커볼트를 고장력 볼트로 대신하는 선행연구의 실험을 토대로 수치해석을 실시하였으며, 해석방법의 타당성을 검증하였다. 또한 현행 설계기준을 분석하여 기둥-기초 연결부 거동에 영향을 미치는 설계변수(앵커의 묻힘깊이, 앵커의 강종, 리브의 높이, 리브의 두께)를 선정하였으며, 설계변수에 따른 기둥-기초 연결부의 거동특성을 비교·분석하였다. 일반 앵커에 비해 고장력 볼트를 적용하는 것이 기둥-기초 연결부의 거동에 유리한 것으로 나타났으며, 고장력 볼트의 최소 묻힘깊이는 기둥 직경()을 기준으로 이상으로 설계하는 것이 합리적이라고 판단된다. 리브의 높이는 이상, 리브의 두께는 베이스플레이트 두께를 기준으로 이상으로 설계하는 것이 합리적이라고 판단된다.
A method for sequencing polymerase chain reaction products can be used to sequence Bacillus subtilis "miniprep" plasmid DNA. (1991)

Several methods for sequencing double-stranded plasmid DNA isolated from E. coli have been described. These methods are usually not effective when used to sequence plasmid DNA isolated from Bacillus subtilis. In the course of developing a simplified version of a previously published protocol for polymerase chain reaction product sequencing, it was found that this protocol could be used for sequencing plasmid DNA isolated from Bacillus subtilis.

Large Graph Construction for Scalable Semi-Supervised Learning (2010)

In this paper, we address the scalability issue plaguing graph-based semi-supervised learningviaasmallnumberofanchorpointswhich adequatelycovertheentirepointcloud. Critically, these anchor points enable nonparametric regression that predicts the label for each data point as a locally weighted average of the labels on anchor points. Becauseconventionalgraphconstructionisinefficient in large scale, we propose to construct a tractable large graph by coupling anchorbased label prediction and adjacency matrix design. Contrary to the Nyström approximation of adjacency matrices which results in indefinite graph Laplacians and in turn leads to potential non-convex optimization over graphs, the proposed graph construction approach based on a unique idea called AnchorGraph provides nonnegative adjacency matrices to guarantee positive semidefinite graph Laplacians. Our approach scales linearly with the data size and in practice usually produces a large sparse graph. Experiments on large datasets demonstrate the significant accuracy improvement and scalability of the proposed approach. 1.
Factors Affecting the Growth of Carbon Nanotubes (2006)

Carbon nanotubes were prepared by using a hot filament chemical vapour deposition (HFCVD) system. Methane diluted in hydrogen was used as the reaction gas and nanosized nickel particles were used as the catalyst. Studies on the effect of catalyst preparation and growth conditions were conducted. The carbon nanotube produced under different conditions were characterized using field emission scanning electron microscopy (FESEM), energy dispersive x-ray (EDX), X-ray diffraction (XRD), Raman spectroscopy and transmission electron microscopy (TEM).

Performance evaluation of IEEE 802.11 fast BSS transition algorithms (2010)

Multimedia services are becoming increasingly available over the wireless devices. Handover performance has a direct impact on user satisfaction from such services. The high transition delay can be unaccepted for the multimedia application or can be a source of disruption on the session. On the other side, IEEE 802.11 standard is being extended with new functionalities. Security and QoS features, included in recent IEEE 802.11-2007 standard, add management frames that are exchanged during the transition process. In consequence the handover delay is increased. IEEE 802.11r-2008 amendment introduces Fast BSS transition (FT) that simplifies the handover process. The authors propose the new handover algorithms based on FT protocol and compare them with existing algorithm. Additionally, simulation experiments are conducted to answer the question if multimedia services can be properly supported in IEEE 802.11r networks. The authors prove that handover delay can be reduced to 22 ms in the average case.
Iatrogenic transmission of Creutzfeldt-Jakob disease (1989)

Creutzfeldt-Jakob disease is a rare progressive neurological disorder which is eventually fatal. Attention has recently been focused upon the iatrogenic transmission of this disease by four published reports of patients developing Creutzfeldt-Jakob disease associated with the administration of human growth hormone preparations originally prepared from human cadaver pituitaries.
Four‐dimensional intensity‐modulated radiation therapy planning for dynamic tracking using a direct aperture deformation (DAD) method (2010)

Nanofluid Heat Transfer Technologies (2009)

As a new research and technology frontier, nanofluids are used to enhance heat transfer including single-phase heat transfer, nucleate boiling heat transfer, flow boiling heat transfer and critical heat flux. This paper presents an overall review of a number of patents on nanofluid heat transfer technologies and their applications for the energy efficiency improvement in various thermal systems in recent years. Although a number of patents on nanofluids heat transfer technologies (more than 20 patents) have been invented, the fundament mechanisms of nanofluid heat transfer have not yet well understood so far. Thus, the applications of these technologies are greatly limited. According to this review, the future developments of these technologies are discussed. In order to be able to put the nanofluid heat transfer technologies into practice, fundamental studies are greatly needed to understand the physical mechanisms. Keywords: Nanofluids, nano-particles, thermal conductivity, single phase heat transfer, nucleate boiling, flow boiling, evaporation, critical heat flux (CHF), heat transfer enhancement, cooling
Design and implementation of an active antenna array for TD-LTE system based on DDS phase shifter (2013)

In this paper, a novel active antenna array is proposed for TD-LTE base station system. This array includes two parallel eight-element uniform linear sub-arrays for the dual polarization operation and provides a usable bandwidth of 100 MHz. Beamforming in the vertical dimension is achieved which improves the performance of cellular mobile communication systems. Each radiation antenna element is integrated with a complete transceiver to reduce the cable loss. Each transmitter is capable of generating up to 21 dBm of output power. Each receiver signal path achieves a gain of 37 dB and a noise figure below 3.5 dB. The eight-path sub-array improves the signal-to-noise ratio at the output by 9 dB in receiving mode compared with a conventional single receiver. Direct digital synthesizer (DDS) chips generate the local oscillator (LO) signal and work as active phase shifters in each path. This active phase shifting infrastructure provides a 360° phase shifting range and accurate tuning step which leads to a beam-steering resolution of 0.1°.
Correlation between echocardiographic endocardial surface mapping of abnormal wall motion and pathologic infarct size in autopsied hearts. (1988)

We previously developed a cross-sectional echocardiographic technique for quantitatively mapping the endocardial surface of the left ventricle and on which regions of abnormal wall motion can be superimposed in their correct spatial distribution. This endocardial mapping technique (EMT) provides a measure of the left ventricular endocardial surface area (ESA in cm2), the area of abnormal wall motion (AWM in cm2), and the overall percent dysfunction (%AWM) as a measure of the functional "infarct size." To test this approach, we compared the EMT measurements with the actual endocardial surface area (in cm2) and pathologic infarct size (both percent infarct by volume and percent endocardial surface overlying infarct) measured at later autopsy in 20 adults (14 men, six women) ranging in age from 47 to 76 years (mean 64 +/- 9.6 years). The median interval from echocardiographic study to death was 19 days (range 1 to 269 days). Patients were divided into two groups based on the age of their infarcts at the time of death: (1) recent (infarct age less than 14 days; mean age 5.3 +/- 4.6 days) and (2) old (infarct age greater than 6 months; mean age 3.6 +/- 3 years). When the left ventricular endocardial surface area at autopsy was compared with the EMT-derived ESA, a close correlation was found (EMT area = 1.17 X autopsy area + 20.4; r = .94, p = .0001), with the systematic difference in the measurements accounted for by systolic arrest, loss of distending pressure, and specimen shrinkage. The echocardiographic measure of infarct size (%AWM) correlated well with the autopsy percent infarction by volume (%AWM = 1.1 X infarct volume + 5.5; r = .82, p = .0001). Similarly, a good correlation was found for the percent abnormal wall motion and the autopsy percent endocardial surface area overlying infarction (%AWM = 0.89 X infarct area - 0.9; r = .89, p = .0001). When the data were examined in relation to the age of the myocardial infarct, the echocardiographic %AWM appeared to overestimate the autopsy infarct size (by percent infarct volume) in the recent infarct group (n = 6), and underestimate the extent in the old infarct group (n = 13). The findings suggest that the EMT will provide a useful quantitative measure of left ventricular endocardial surface area and the extent of ischemic/infarct-related dysfunction.

Investing in Reduced Setups in the EOQ Model (1985)

This paper is motivated by the observation that the Japanese have devoted much time and energy to decreasing setup costs in their manufacturing processes and that there has been little in the way of a formal framework available to use to think about such efforts. The object of this paper is to begin to provide such a framework. The framework developed identifies only one aspect of the advantages of reducing setups, namely reduced inventory related operating costs. The other advantages, such as improved quality control, flexibility, and increased effective capacity, are not accounted for in this paper. Nevertheless, substantial reductions in setups may be warranted based solely on the benefits identified in this paper. The approach taken here introduces an investment cost associated with changing the (current) setup level and adds a per unit time amortization of this cost to the other costs identified in the standard EOQ model. The general problem becomes that of minimizing the sum of a convex and a concave function. In two special cases, the minimization can be carried out explicitly. In one of these cases, numerous interpretations of the results are made, including comparisons of Japanese and American practices. For example, holding other parameters constant, there is a critical sales level such that investment is made in reducing setups if and only if the sales rate is above that level. When such investment is made, the optimal lot size is independent of the sales rate. The paper also addresses the joint selection of the setup cost and the sales rate. Selection of the sales rate is seen as incorporating explicit production and holding costs into the classical monopolist’s pricing problem. An explicit solution is obtained for the model postulated.
Single-atom point contacts in the superconducting state (1994)

Recently it has become possible to fabricate long-term stable point contacts with a constriction as small as a single atom. Here we present experimental investigations on one-atom point contacts in the superconducting state. An applied pressure or tensile force on this atom results in large effects in the superconducting properties. Furthermore, we show that one-atom point contacts can be broken and reestablished in a perfectly reproducible manner.

Identification of triptolide, a natural diterpenoid compound, as an inhibitor of lung inflammation (2010)

Inflammation is associated with various pulmonary diseases and contributes to the pathogenesis of acute lung injury. We previously identified a proinflammatory signaling pathway triggered by G protein-coupled receptors (GPCRs) in which stimulation of G(q)-coupled GPCRs results in activation of the transcription factor NF-kappaB. Because damage to the lung causes the release of multiple mediators acting through G(q)-coupled GPCRs, this signaling pathway is likely to contribute to inflammatory processes in the injured lung. In an effort to identify novel inhibitors of lung inflammation, the National Institutes of Health Clinical Collection, a library of 446 compounds, was screened for inhibitory activity toward production of IL-8 induced by stimulation of the G(q)-coupled tachykinin 1 receptor with substance P in A549 cells. Twenty-eight compounds that significantly inhibited substance P-induced IL-8 production were identified. The most potent inhibitor was triptolide, a diterpenoid compound from Tripterygium wilfordii Hook F, a vine used in traditional Chinese medicine for the treatment of autoimmune diseases. Triptolide inhibited IL-8 production induced by substance P with an IC(50) of 2.3 x 10(-8) M and inhibited NF-kappaB activation in response to an agonist of the protease-activated receptor 2 with an IC(50) of 1.4 x 10(-8) M. Anti-inflammatory effects of triptolide were assessed in vivo using a chlorine gas lung injury model in mice. Triptolide inhibited neutrophilic inflammation and the production of KC (Cxcl1) in the lungs of chlorine-exposed mice. The results demonstrate that triptolide exhibits anti-inflammatory activity in cultured lung cells and in an in vivo model of acute lung injury.
Ten o'clock closing - the effect of the change in hotel bar closing time on road accidents in the metropolitan area of Victoria (1969)

In the state of Victoria, on February 1, 1966, closing time of hotel bars was altered from 6 pm to 10 pm. Sufficient time has now elapsed to allow an assessment of the long term effects of the change, and two questions arise: (a) has the change in closing time caused any change in the total number of road accidents? (b) has the hourly distribution of road accidents altered? the purpose of this study is to find answers to these questions. The investigation was confined to road traffic accidents in the Melbourne metropolitan area, and to those in which casualties were incurred. Significant changes did occur in hourly distribution of accidents within the period 6 to 11 pm: a decrease from 6 to 7pm and an increase from 10 to 11 pm.
Modulation of extracellular pH by glutamate and GABA in rat hippocampal slices (1992)

1. Alkaline extracellular pH transients evoked by afferent stimulation, and local pressure ejection of glutamate and gamma-aminobutyric acid (GABA), were studied in the CA1 region of rat hippocampal slices. Amino acid-evoked responses were obtained by use of a dual micromanipulator, with the tip of a double-barreled pH-sensitive microelectrode positioned 50 microns from a pressure ejection pipette. 2. At 31 degrees C, in Ringer solutions buffered with 26 mM HCO3- and 5% CO2, mean extracellular pH in submerged 300-microns slices was 7.15 +/- 0.12 (n = 27 slices), at a tissue depth of approximately 150 microns. In Ringer buffered with 35 mM HCO3- and 5% CO2, extracellular pH was 7.29 +/- 0.10 (n = 19 slices). 3. Repetitive stimulation of the Schaffer collaterals caused an extracellular alkaline shift in stratum oriens, pyramidale, and radiatum, averaging 0.05 +/- 0.03 pH units among all regions (n = 138), with a maximum response of 0.16 pH units. Alkaline transients of similar appearance were obtained by local ejection of glutamate (0.01-0.12 pH units, n = 110) and GABA (0.01-0.18 pH units, n = 137). Control ejection of these amino acids into dilute agar caused only small acid shifts. 4. Superfusion of 100 microM picrotoxin abolished the GABA-evoked alkaline shift but failed to inhibit the Schaffer collateral- and glutamate-evoked alkalinizations. 5. Superfusion of 10(-5)-10(-3) M acetazolamide acidified the baseline by 0.05-0.10 pH units and amplified the Schaffer collateral- and glutamate-evoked alkaline shifts.(ABSTRACT TRUNCATED AT 250 WORDS)
