Design strategies and decoupling techniques for reducing the effects of electrical interference in mixed-mode IC's (1997)

A key issue in the successful integration of analog circuits is a stable analog power supply. Traditional on-chip decoupling methods exhibit transients in the supply or voltage drops and power losses. This paper introduces the RLC decoupling method that features an enhanced transient response while being especially suited for low-power, low voltage applications. Both a theoretical and a practical approach are presented together with measurement results. As the benefits of a stable local power supply can be lost by the inadequate connection of two subcircuits with relative variations on the local grounds, a differential approach of signal transfer is proposed. Furthermore, the effect of a good local decoupling can be deteriorated by substrate noise, so some attention is given to this problem too.
BI-FREQUENCY ANALYSES OF MOORING LINE DYNAMICS (1993)

A method of calculation of mooring line dynamics is proposed in this paper. It is based on the method of perturbation. The perturbation equations up to second order were obtained and solved in the frequency domain to obtain the frequency response function, while the impulse response function in the time domain can be obtained by applying the Fourier inverse transform on such frequency responses. The time history of the response of the mooring line can be calculated by a convolution integral which involves the input time history and the corresponding impulse response function. In order to verify the validity of the proposed method, an experiment of an oscillating model mooring line was conducted in a water flume. The experiment measured both the time history and the first-order frequency response function, which showed good agreement with theoretical results. A theoretical calculated second-order frequency response function is illustrated in this paper.
Trading off Reliability and Cost in Optimal Water Distribution System Design (2003)

Most design engineers would list "reliability" as the primary objective in water system design while most optimization models focus on "least cost" as the primary objective. Of course, both objectives are important and the key to successful design lies in effectively trading off both objectives. Least-cost design methods, using a single (or handful of) design scenario(s) to evaluate the hydraulic performance of a solution do not work for evaluation of reliability because there are numerous modes of failure for each solution trial. Within reason, each of these solutions needs to be evaluated for multiple loadings and important elements being taken out of service. This paper evaluates several alternative approaches for trading off reliability and costs in a genetic algorithm optimization model for a real system.

Motion detection with non-stationary background (2002)

This paper proposes a new method for moving object (foreground) detection with non-stationary background using background subtraction. While background subtraction has traditionally worked well for stationary backgrounds, the same cannot be implied for a nonstationary viewing sensor. To a limited extent, motion compensation for non-stationary backgrounds can be applied, but in practice, it is difficult to realize the motion compensation to sufficient accuracy and the background subtraction algorithm will fail for a moving scene. The problem is further compounded when the moving target to be detected/tracked is small, since the pixel error in motion compensating the background will subsume the small target. A spatial distribution of Gaussians (SDG) model is proposed to deal with moving object detection having motion compensation which is only approximately extracted. The distribution of each background pixel is temporally and spatially modeled; a pixel in the current frame is then classified based on this statistical model. The emphasis of this approach is on the robust detection of moving objects even with approximately accurate motion compensation, noise, or environmental changes. Test cases involving the detection of small moving objects with a highly textured background and a pan-tilt tracking system are demonstrated successfully.

Homology Modeling of Human Alpha-Glucosidase Catalytic Domains and SAR Study of Salacinol Derivatives (2012)

Maltase-glucoamylase (MGAM) and sucrase-isomaltase (SI) belong to human intestinal alpha-glucosidase and their N-terminal side catalytic domains are called NtMGAM and NtSI, and their C-terminal side catalytic domains are called CtMGAM and CtSI. As an antidiabetic, alpha-glucosidase inhibitor is required to bind to all of these domains to inhibit disaccharides hydrolysis. Salacinol and kotalanol isolated from Salacia reticulata are novel seed compounds for al-pha-glucosidase inhibitor. Even though the complex structures of NtMGAM or NtSI have been determined experimen-tally, those of CtMGAM and CtSI have not been revealed. Thus, homology modeling for CtMGAM and CtSI has been performed to predict the binding mode of salacinol and its derivatives for each domain. The binding affinities for these compounds were also calculated to explain the experimental structure-activity relationships (SARs). After a docking study of the derivatives to each catalytic domain, the MM/PBSA method has been applied to predict the binding affinities. The predicted binding affinities were almost consistent with the experimental SARs. The comparison of the complex structures and binding affinities provided insights for designing novel compounds, which inhibit all catalytic domains.
Electrical properties of SrBi2Ta2O9 ferroelectric thin films at low temperature (2002)

The temperature dependence of electrical properties for SrBi2Ta2O9 thin film capacitors with platinum electrodes (Pt/SBT/Pt) on silicon wafers was studied from 10 to 300 K. With a decrease in temperature from 300 to 200 K, the remanent polarization of the thin films shows about an 11% reduction from its 300 K value; however, it is reduced by about 87% reduction from its 200 K value when the temperature drops from 200 to 100 K. With a decrease to 200 K, the polarization fatigue was significant, and the capacitor shows an approximate 29% reduction in polarization from its initial value following 1010 cycles. The dielectric response and leakage current of the thin films were also studied over the same lower temperature region. These results are helpful in the understanding of the fatigue-free behavior observed in SrBi2Ta2O9 thin films at room temperature and provide additional insight into their use for ferroelectric memory applications.
Design of a file server operating system (2002)

This paper describes the design of a file server operating system called Cypress. The design of Cypress is aimed at improving the file server response time through exploiting latest hardware advances. Cypress is distinctive in its caching and management strategies that take advantage of the large-capacity disk caches, tens to hundreds megabytes, and the powerful processors in contemporary file servers. If compared with general-purpose operating systems that are installed to perform file server operations, Cypress enjoys another advantage of featuring more predictable response time for real-time applications. Based on our measurement on our first version of implementation, the average hit response times of Cypress when running on a Intel 80486 CPU based PC with 32-megabyte memory are 1.38 ms and 1.39 ms for read and write requests, respectively.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Reversal of Multidrug Resistance by the P-Glycoprotein Modulator, LY335979, from the Bench to the Clinic (2001)

Multidrug resistance may be conferred by P-glycoprotein (Pgp, ABCB1) or the multidrug resistance associated protein (MRP). These membrane proteins are members of the ATP binding cassette transporter superfamily and are responsible for the removal from the cell of several anticancer agents including doxorubicin. Modulators can inhibit these transporters. LY335979 is among the most potent modulators of Pgp with a Ki of 59 nM. LY335979 is selective for Pgp, and does not modulate MRP-mediated resistance by MRP1 (ABCC1) and MRP2 (ABCC2). LY335979 significantly enhanced the survival of mice implanted with Pgp-expressing murine leukemia (P388/ADR) when administered in combination with either daunorubicin, doxorubicin or etoposide. Coadministration of LY335979 with paclitaxel compared to paclitaxel alone significantly reduced the tumor mass of the Pgp-expressing UCLA-P3.003VLB lung carcinoma in a xenograph model and delayed the development of tumors in mice implanted with the parental drug-sensitive UCLA-P3 tumor. LY335979 was without significant effect on the pharmacokinetics of these anticancer agents. This may be due impart to its poor inhibition of four major cytochrome P450 isozymes important in metabolizing doxorubicin and other oncolytics. The selectivity and potency of this modulator allows the clinical evaluation of the role of Pgp in multidrug resistance. LY335979 is currently in clinical trials.
The network Unix system (1975)

A Network Interface Program (NIP) is that part of an operating system which interfaces with similar entities in a network. Normally, the NIP is a collection of software routines which implement interprocess communication, interhost protocols, data flow controls, and other necessary executive functions. This paper discusses the organization of the NIP currently being used with the Unix operating system on the ARPA network. The Network Unix system is noteworthy because of the natural way that network and local functions are merged. As a result the network appears as a logical extension to the local system - from the point of view of both the interactive terminal and user program.
Gigascope (2003)

We have developed Gigascope, a stream database for network applications including traffic analysis, intrusion detection, router configuration analysis, network research, network monitoring, and performance monitoring and debugging. Gigascope is undergoing installation at many sites within the AT&T network, including at OC48 routers, for detailed monitoring. In this paper we describe our motivation for and constraints in developing Gigascope, the Gigascope architecture and query language, and performance issues. We conclude with a discussion of stream database research problems we have found in our application.
Biological countermeasures in space radiation health. (2003)

Exposure to the types of ionizing radiation encountered during space travel may cause a number of health-related problems, but the primary concern is related to the increased risk of cancer induction in astronauts. The major types of radiation considered to be of importance during space travel are protons and particles of high atomic number and high energy (HZE particles). It is now clear that biological countermeasures can be used to prevent or reduce the levels of biological consequences resulting from exposure to protons or HZE particles, including the induction of cancer, immunosuppression and neurological defects caused by these types of ionizing radiation. Research related to the dietary additions of agents to minimize the risks of developing health-related problems which can result from exposure to space radiations is reviewed.
Comparative Laboratory Selection and Field Testing of Polymers for Selective Control of Water Production in Gas Wells (1995)

ABSTRACT Intensive comparative feasibility studies were performed in different laboratories in order to select the most promising polymer based technology for water control in gas production and storage wells exhibiting low matrix permeability, high temperature and high produced brine salinity. Core flow experiments performed under reservoir conditions with different commercial available chemical systems have pointed out to the superiority of two relatively low-molecular-weight vinyl sulfonated/ vinyl amide/ acrylamide terpolymers over other polymers to decrease selectively and effectively the water permeability without affecting the gas flow. These polymers have excellent compatibility with all types of reservoir brines and good thermal stability up to 150°C. Furthermore, because of their high shear resistance, and excellent injectability even in low permeability cores, solutions of these polymers can be pumped at high injection rates with a moderate wellhead pressure. Based on the promising results of the lab tests the first field treatment was performed in January 1993 on an abandoned gas producing well from a sandstone reservoir with a BHT of about 130°C, an average matrix permeability of 0.01 μm2 and a produced brine salinity of more than 300 g/1 TDS. This well was loaded up with water. The polymer solutions were injected at a well head pressure not exceeding 5 MPa without any problem. The treatment returned a daily gas production of more than 100,000 m3 to the well. The water production was reduced from almost 90 m3/d to less than 1 m3/d. The second treatment was performed in May 1994 on a candidate well in a gas storage sandstone reservoir with a BHT of 87°C, matrix permeability of 0.1μm2 and brine salinity of 300 g/l. According to the lab feasibility studies this time a terpolymer with a lower molecular weight was used. As a consequence of the treatment the well is showing far better gas injection characteristics. The effect on the gas and water production can only be evaluated at the end of the winter production period in March 1995.
New Bilaterally Linked Mesogens in Main-Chain Polymers with Exhibition of Biaxial Fluctuation in Nematic Phase (1998)

The synthesis of a new series of liquid crystalline polyesters with bilaterally linked mesogens is described. The investigation of their mesomorphic behaviors by differential scanning calorimetry, X-ray diffraction, and polarization microscopy is presented. These new polymers exhibit only the nematic phase. X-ray diffraction studies reveal the existence of biaxial fluctuation in the nematic phase in two homologues of the series.
Solute-Free Interfacial Zones in Polar Liquids (2010)

Large, solute-free interfacial zones have recently been described in aqueous solutions. Found next to hydrophilic surfaces, these "exclusion zones" are commonly several hundred micrometers wide and represent regions of water that appear to be more ordered than bulk water. We report here that other polar solvents including methanol, ethanol, isopropanol, acetic acid, D(2)O, and dimethyl sulfoxide (DMSO) show similar near-surface exclusion zones, albeit of smaller magnitude. Microelectrode measurements show that these zones are negatively charged and grow in response to incident infrared radiation, similar to exclusion zones in aqueous solutions. Hence, near-surface exclusion zones appear to be features characteristic not only of water but of other polar liquids as well.

Electrodeposition of Crack-Free CuGaSe[sub 2] Thin Films from Single Bath (2008)

Cu–Ga–Se precursor thin films have been prepared by electrodeposition techniques on Mo substrates and annealed to crystallize at . The films were characterized by scanning electron microscope, energy dispersive X-ray spectrometry, and X-ray diffraction. The electrodeposited films without an addition agent presented a lot of cracks due to the tension by the formation of Ga–O species, and the crystallized films were aggregated. Addition of as both a supporting electrolyte and a pH adjuster and gelatin as a brightener realized the crack-free films without aggregation. It was found that the composition and morphology of the films were highly dependent on the composition and the addition agent of the solution.

Transition‐metal nanoparticles: synthesis, stability and the leaching issue (2008)

Abstract This perspective examines the state‐of‐the‐art of catalysis by metal nanoparticles. We outline various methods for preparing metal nanoparticle suspensions, and highlight the role of the stabilizers and the stabilizing principles. Subsequently, we examine some catalytic applications of homometallic and bimetallic nanoparticle suspensions in a variety of reactions. The cases are divided according to the stabilizing agent: polymers, dendrimers, ionic liquids, surfactants, micelles and micoremulsions, ligands and solid supports. We explain the importance of atom/ion leaching (all too frequent in nanoparticle catalysis, especially for the catalytically active group VIII metals) and consider ways of minimizing it. The future perspectives of nanoparticles as catalysts are discussed. Copyright © 2008 John Wiley & Sons, Ltd.
