Applications of semiconductor test economics, and multisite testing to lower cost of test (2003)

This paper develops a Semiconductor Test Economic Model that can easily be applied to lowering overall cost of test and improving throughput. The "Model", designed to take the complexity out of Test Economics, describes all the variables that make up cost per unit, and using managerial economic concepts, illustrates how they interact with each other, as well as the overall production goal of minimizing costs while maximizing throughput. This paper is written for Test Managers, Test Engineers, Product Engineers, and ATE Capital Equipment Buyers for the purpose of gaining insight analyzing test economics, in order to make better decisions on everyday Manufacturing issues related to: test time reduction, multisite testing, yield, handler index time, ATE utilization, and ATE purchasing.

In this rodent model of acute lung injury after repeated pulmonary lavage, AT2 receptor stimulation attenuates pulmonary inflammation but does not improve gas exchange.
The Detection and Estimation of Part Per Billion Concentrations of Hydrocarbons (1965)

The addition of a freeze-out step in liquid nitrogen prior to analysis by gas chromatography with flame ionization detection permits the accurate determination of C2 and higher hydrocarbons in the part per billion (ppb) range. Concentrations of C2 and higher hydrocarbons have been measured in commercial cylinders of nitrogen, helium and hydrogen. Using a 150 ml sample of gas, recovery of ppb concentrations is 95 to 100 percent.
Mimic of Protein: A Highly pH‐Sensitive and Thermoresponsive Polyampholyte (2011)

Abstract As a mimic of protein, a polyampholyte‐based material should be able to duplicate the properties and functions of protein. A polyampholyte that is highly sensitive to both pH and temperature under physiological conditions is obtained when 80% butylamide‐terminated poly(amidoamine) dentron is grafted to the backbone of styrene and maleic anhydride. The phase separation occurs at 33.7 °C at pH = 6.20, while the transition point increases to 43.9 °C at pH = 6.30. The superior performance is the consequence of the cooperative interactions among basic, acidic, and thermoresponsive groups. The polyampholyte with a suitable isoelectric point provides a platform for the development of multifunctional materials for biomedical applications.

Chelating resin method for estimation of sludge‐cadmium bioavailability (1991)

Abstract A chelating resin procedure was developed to predict the plant uptake of Cd by municipal sewage sludges applied to land. Seventeen anaerobically digested sludges were sampled to give a range of total Cd content of 0.07 to 2.02 mmol/kg. Sludge suspensions [20 g in 100 mL 0.05 M Ca(NO3)2] were equilibrated with 1 g Chelex 100 resin placed in dialysis tubing and shaken at 200 rpm for 16 h. Resin‐extractable Cd was compared with sludge solution Cd (CdT and Cd2+) in equilibrium with 0.05 M Ca(NO3)2, and 0.05 M Ca(NO3)2 containing 50 (μM Na‐EDTA (ethylenediaminetetraacetate). Resin extractable Cd was correlated with Cd uptake by sudax, a sorghum/sudangrass hybrid (Sorghum bicolar), grown in Spinks loamy sand (Typic Udipsamment) amended with each of the sludges to give a constant Cd concentration of 22 μmol/kg soil. Resin extractable Cd ranged from < 0.1 to 48 μmol/kg. Resin extracted between zero and 5.3% of total sludge Cd. Resin extractable Cd was highly correlated with CdT and Cd2+ in 0.05 M Ca(NO3)2 (R2 = 0.97 and 0.98, respectively), and with 0.05 M Ca(NO3)2 containing 50 μM NaEDTA (R2 = 0.97 and 0.98, respectively). There was a lower correlation with total sludge Cd and soil solution Cd (R2 = 0.53 and 0.63, respectively). Cadmium concentration in sudax was highly correlated with resin extractable sludge Cd (R2 = 0.92). When the two sludges with highest total sludge Cd were dropped, the correlation dropped (R2 = 0.57), but resin extractable Cd predicted Cd uptake as effectively as CdT and Cd2+ in Ca(NO3)2 or Ca(NO3)2/EDTA. Resin extraction appears to be a promising method of assessing the potential bioavailability of sludge Cd.
Gate leakage and its reduction in deep submicron SRAM (2005)

In this work the impact of gate leakage on SRAM is described and two approaches for reducing gate leakage currents are examined in detail. In one approach, the supply voltage is reduced while in the other the potential of the ground node is raised. In both the approaches the effective voltage across SRAM cell is reduced in inactive mode using a dynamic self-controllable switch. Simulation results based on BPTM (Berkeley Predictive Technology Model) for 45nm channel length device show that the scheme in which supply voltage level is reduced is more efficient in reducing gate leakage than the one in which ground node potential is raised. Results obtained show that 96% reduction in the leakage currents of SRAM can be achieved.
Placental Growth Factor in Acute Coronary Syndrome Patients with Non ST-Elevation (2009)

Markers of plaque instability are considered as predictors of future coronary events in patients with non ST-elevation myocardial infarction (NSTEMI) in acute coronary syndrome (ACS). The aim of this study was to determine the role of placental growth factor (PlGF) as a possible predictor of future coronary events such as non-fatal myocardial infarction or cardiac death measured at the admission and 30 days after discharge. We prospectively collected data from 102 patients admitted to the emergency department (ED) for ACS with chest pain at rest within the preceding 12 hours who were evaluated by risk factors and electrocardiogram changes (ECG). The time course of PlGF levels determined on 102 patients showed a mean value 13.21 ng/L and standard deviation 8.76 ng/L but in the sample of the 53 patients who survived after 30 days, these values decreased to 10.48 ng/L and 5.45 ng/L, respectively. Results of this study indicate a clinically useful role of PlGF in the detection of ACS and NSTEMI patients who are at a higher risk for different cardiovascular disorders within 30 days of admission.
Dislocation-free InSb grown on GaAs compliant universal substrates (1997)

An innovative compliant GaAs substrate was formed by wafer bonding a 30 Å GaAs layer to a bulk GaAs crystal with a large angular misalignment inserted about their common normals. InSb epitaxial layers, which is about 15% lattice mismatched to GaAs, have been grown on both compliant substrates and conventional GaAs substrates. Transmission electron microscopy studies showed that the InSb films grown on the compliant substrates have no measurable threading dislocations, whereas the InSb films on the conventional GaAs substrates exhibited dislocation densities as high as 1011 cm−2. The observations made here suggest that the defect-free heteroepitaxial growth of exceedingly large lattice-mismatched crystals can be achieved with compliant universal substrates.
A One ppm NDIR Methane Gas Sensor with Single Frequency Filter Denoising Algorithm (2012)

A non-dispersive infrared (NDIR) methane gas sensor prototype has achieved a minimum detection limit of 1 parts per million by volume (ppm). The central idea of the design of the sensor is to decrease the detection limit by increasing the signal to noise ratio (SNR) of the system. In order to decrease the noise level, a single frequency filter algorithm based on fast Fourier transform (FFT) is adopted for signal processing. Through simulation and experiment, it is found that the full width at half maximum (FWHM) of the filter narrows with the extension of sampling period and the increase of lamp modulation frequency, and at some optimum sampling period and modulation frequency, the filtered signal maintains a noise to signal ratio of below 1/10,000. The sensor prototype provides the key techniques for a hand-held methane detector that has a low cost and a high resolution. Such a detector may facilitate the detection of leakage of city natural gas pipelines buried underground, the monitoring of landfill gas, the monitoring of air quality and so on.
Spermine as a modulator of membrane fusion: interactions with acidic phospholipids (1986)

The interaction of spermine with acidic phospholipids was investigated for its possible relevance to membrane fusion. Equilibrium dialysis was used to measure the binding of spermine and calcium to large unilamellar vesicles (liposomes) of phosphatidate (PA) or phosphatidylserine (PS). Spermine bound to isolated PA and PS liposomes with intrinsic association constants of approximately 2 and 0.2 M-1, respectively. Above the aggregation threshold of the liposomes, the binding of spermine increased dramatically, especially for PA. The increased binding upon aggregation of PA liposomes was interpreted as evidence for the formation of a new binding complex after aggregation. Spermine enhanced calcium binding to PA, while it inhibited calcium binding to PS, under the same conditions. This difference explained the small effect of spermine on the overall rate of calcium-induced fusion of PS liposomes as opposed to the large effect on PA liposomes. The rate increase could be modeled by a spermine-induced increase in the liposome aggregation rate. The preference for binding of spermine to PA over PS suggested a preference for accessible monoesterified phosphate groups by spermine. This preference was confirmed by the large effects of spermine on aggregation and overall fusion rates of liposomes containing phosphatidylinositol 4,5-diphosphate. The large spermine effects on these liposomes compared with phosphatidate- or phosphatidylinositol-containing liposomes suggested that spermine has a strong specific interaction with phosphatidylinositol 4,5-diphosphate. Clearly, phosphorylation of phosphatidylinositol can lead to a large change in the spermine sensitivity of membrane fusion.
Effects of the P<sub>2</sub>‐purinoceptor antagonist, suramin, on human platelet aggregation induced by adenosine 5′‐diphosphate (1992)

1. The effects of suramin, a trypanocidal drug which has been reported to be a P2-purinoceptor antagonist on smooth muscle, were investigated in human platelets, where adenosine 5'-diphosphate (ADP) induces aggregation by acting on a subtype of purinoceptors which has been called P2T. 2. Suramin (100 microM) had no inhibitory effect on ADP-induced platelet aggregation in plasma, even after 40 min incubation in the presence of bacitracin, a peptidase inhibitor, and did not affect the ability of adenosine 5'-triphosphate (ATP) (40 microM) to inhibit competitively ADP-induced aggregation. This lack of effect of suramin on platelets in plasma is probably due to its extensive binding to plasma proteins. 3. In washed platelets, suramin (50-400 microM) acted as an apparently competitive antagonist, causing parallel shifts to the right of the log concentration-response curve to ADP. No depression of the maximal response to ADP was observed at concentrations of suramin (50-150 microM) for which full log concentration-response curves to ADP could be obtained, but the slope of the Schild plot was around 2, indicating that this antagonism was not simply competitive. The apparent pA2 value for suramin, taken from this Schild plot, was 4.6. 4. Suramin (200-400 microM) also noncompetitively inhibited aggregation induced by U46619 (a thromboxane receptor agonist) or by 5-hydroxytryptamine in the presence of adrenaline (100 microM), and caused a depression of the maximal response to these agonists. This nonspecific effect of suramin may explain the high Schild plot slope obtained against ADP.5. These results provide evidence that the ADP receptor on human platelets is indeed similar to the P2-purinoceptors responding to adenine nucleotides on smooth muscle and other tissues, and show that suramin cannot distinguish between the proposed subtypes of the P2-purinoceptors.
Three-Dimensional Display from Cross-Sectional Tomographic Images: An Application to Magnetic Resonance Imaging (1987)

A system has been developed to facilitate three-dimensional visualizations of tomographic image data. Tomographic techniques yield parallel planes of data at discrete locations; thus, a series of images comprises a three-dimensional database. From this database, a system has been developed to perform three-dimensional calculations, measurements, and display. The system consists of a conventional two-dimensional video monitor, a digitizing tablet for user interaction and region-of-interest (ROI) definition, application-oriented computational software, and an image display system for true three-dimensional database visualization. The three-dimensional display makes use of a varifocal mirror system with vector graphics capability. Through the use of specialized contouring software, we illustrate the utility of this system in the specific examples of displays prepared from magnetic resonance (MR) images of the brain and carotid arteries. It can be concluded that this system will provide valuable diagnostic and physiologic information that will provide added insight into normal and abnormal structure and its relationship to function.

Effects of fire on germination and viability of rubber vine ( <i>Cryptostegia grandiflora</i> ) seeds (2000)

Studies were undertaken at 2 sites in northern Queensland (Wrotham Park and Ten Mile Creek) to quantify the effects of fire on germination and viability of both loose rubber vine seeds and seeds held within pods. Seed lots were placed at a range of positions within the vertical profile of rubber vine infestations; 0.5 cm below ground (loose seeds only), on bare ground, below fuel, above fuel and on crowns of free-standing rubber vine. The influence of seed age (0 and 1 year old) and seed plumage (with and without plumes) was also examined for loosely held seeds. Late season fires were imposed at both Wrotham Park and Ten Mile Creek, with an additional early season fire undertaken at Ten Mile Creek to enable comparison between seasonal fires. Maximum fire temperatures reached during burning averaged 853, 827 and 871°C for Wrotham Park, Ten Mile Creek early and Ten Mile Creek late season fires, respectively. The temperatures that seeds were exposed to depended on their location within the vertical profile, with temperatures above fuel &gt; below fuel &gt; on rubber vine crown &gt; bare ground &gt; 0.5 cm below ground. Seed viability after burning ranged from 0 to 100%, with seeds generally most affected if located above or below the fuel, and least affected if buried below ground. The age of seed and the presence of seed plumes interacted with seed placement so that seed germination and viability of loose seeds were affected. Some seeds remained viable, but were inhibited from germinating, particularly if located 0.5 cm below ground. Positive, non-linear relationships occurred between seed mortality and maximum temperature and between seed mortality and the duration of exposure. These results suggest that fire may inhibit germination and kill a substantial proportion of rubber vine seeds.

Heat Transmission in Surface Condensers (1941)

The paper deals with the resistance to heat flow on the steam side of surface condenser tubes, and begins with a brief reference to theoretical and experimental work on the subject. The separation of the total resistance from steam to water into its component resistances and the estimation of the resistance from steam to tube by the remainder method is then discussed, an example of the procedure used by the author in the preparation of the paper being given in Appendix I. The probable factors in the conditions of operation which produce the variations observed in apparent resistance to heat flow from steam to tubes, as estimated by the remainder method from the results of condenser tests, are then considered. The validity of the assumptions made with regard to these factors is tested by a re-examination of the results of four well-known condenser tests in which the amount of air leakage was recorded. The conclusions and observations to which this examination would appear to give rise are then stated. An alphabetical list of references is given in Appendix II.
Monolithic GaAs Interdigitated Couplers (1983)

This paper deseribes the design, fabrication, and performance of two monolithic GaAs C-band 90° interdlgitiited couplers with 50- and 25-Omega impedances, respectively. A comparison of the performance of' these two couplers shows that the 25-Omega coupler has the advantages of lower loss and bigher fabrication yield. The bafanced amplifier configuration rising 25-Omega couplers will require, a fewer number of elements in the input-output matching circuit of the FET amplifier. The fewer number of matcfdng elements results in great savings in the GaAs real estate for microwave monolithic intergrated circuits (MMIC's). Both the couplers have been fabricated on a 0.1-mm-thick GaAs S1 substrate. The measured results agree quite well with calculated results. The losses of the 50- and 25-Omega couplers are 0.5 and 0.3 dB, respectively, over the 4-8-GHz frequency band.
A Security Context Transfer Method for Integrated Space Network (2008)

The context transfer can improve handover performance effectively through avoid performing the entire protocol exchange with the mobile nodes from scratch, so it have received a lot of attention recently. This paper introduced the present research situation of context transfer, and proposed a security context transfer method for integrated space network, that enables authorized security context transfers. This paper also highlights some the security issues, transport reliability, and MPHR selection algorithm, providing suggestions to overcome those issues. The security context transfer (SCT) proposed by this paper integrated predictive transfer with requested transfer that is transparent for mobile nodes. SCT may allow better support for mobile nodespsila mobility and security. SCT also can reduce latency and packet losses, enhanced reliability and avoid the re-initiation of signaling from the mobile node, so that the applications running on mobile nodes can operate with minimal disruption.
Ocular Findings in Botulism Type B (1979)

In April 1977, fifty-nine persons became ill with type B botulism in a large, common-source outbreak. A combination of signs and symptoms that should make the clinician strongly suspect botulism was derived from the histories and ocular findings of these persons. Certain signs of third cranial nerve dysfunction reliably predicted in which patients ventilatory insufficiency would develop.

A Cytoplasmic Form of Gaussia luciferase Provides a Highly Sensitive Test for Cytotoxicity (2016)

The elimination of unfavorable chemicals from our environment and commercial products requires a sensitive and high-throughput in vitro assay system for drug-induced hepatotoxicity. Some previous methods for evaluating hepatotoxicity measure the amounts of cytoplasmic enzymes secreted from damaged cells into the peripheral blood or culture medium. However, most of these enzymes are proteolytically digested in the extracellular milieu, dramatically reducing the sensitivity and reliability of such assays. Other methods measure the decrease in cell viability following exposure to a compound, but such endpoint assays are often confounded by proliferation of surviving cells that replace dead or damaged cells. In this study, with the goal of preventing false-negative diagnoses, we developed a sensitive luminometric cytotoxicity test using a stable form of luciferase. Specifically, we converted Gaussia luciferase (G-Luc) from an actively secreted form to a cytoplasmic form by adding an ER-retention signal composed of the four amino acids KDEL. The bioluminescent signal was >30-fold higher in transgenic HepG2 human hepatoblastoma cells expressing G-Luc+KDEL than in cells expressing wild-type G-Luc. Moreover, G-Luc+KDEL secreted from damaged cells was stable in culture medium after 24 hr at 37°C. We evaluated the accuracy of our cytotoxicity test by subjecting identical samples obtained from chemically treated transgenic HepG2 cells to the G-Luc+KDEL assay and luminometric analyses based on secretion of endogenous adenylate kinase or cellular ATP level. Time-dependent accumulation of G-Luc+KDEL in the medium increased the sensitivity of our assay above those of existing tests. Our findings demonstrate that strong and stable luminescence of G-Luc+KDEL in human hepatocyte-like cells, which have high levels of metabolic activity, make it suitable for use in a high-throughput screening system for monitoring time-dependent cytotoxicity in a limited number of cells.
