Isolation of a yeast heptaglucoside that inhibits monocyte phagocytosis of zymosan particles. (1989)

To isolate a unit ligand recognized by human monocyte beta-glucan receptors, acid-solubilized oligoglucosides were prepared by partial acid hydrolysis of purified yeast cell walls, gel filtered sequentially on Bio-Gel P-4 and P-2, derivatized with 2-aminopyridine, and separated by normal-phase HPLC. Ligand recognition was assessed by quantitating the effect of pretreatment with isolated materials on the capacities of adherent monocytes to phagocytose zymosan particles. Partial acid hydrolysis solubilized 23 +/- 4% (mean +/- SD; n = 7) of the cell wall glucans; at an input of 50 micrograms/ml, the solubilized products reduced the numbers of monocytes ingesting zymosan by an average of 44%. Gel filtration of acid-solubilized glucans on Bio-Gel P-4 revealed several peaks with phagocytosis-inhibiting activity, and fractions from the peak containing the smallest oligoglucosides, which accounted for 10 +/- 2% (mean +/- SD; n = 7) of the carbohydrate applied, were pooled. Further purification on Bio-Gel P-2 resolved this phagocytosis-inhibiting activity to a single peak that contained apparent heptaoses and accounted for 8 +/- 2% (mean +/- SD; n = 6) of the carbohydrate applied. At a concentration of 0.5 microgram/ml, the oligoglucosides pooled from the Bio-Gel P-4 and P-2 columns reduced the numbers of ingesting monocytes by 45 +/- 1% and 42 +/- 7% (mean +/- SD; n = 3), respectively. When derivatized with 2-aminopyridine, the oligoglucosides were resolved by HPLC to a number of peaks; a peak that eluted as an apparent heptaglucoside contained virtually all the inhibitory activity and accounted for only 6.6 +/- 0.7% (mean +/- SD, n = 7) of the carbohydrate applied. Gas chromatography analysis revealed only glucose and FAB-mass spectrometric analysis showed only heptaglucoside and no noncarbohydrate molecules. At a concentration of 1.6 ng/ml, the derivatized yeast heptaglucoside reduced the numbers of monocytes ingesting zymosan and glucan particles by 44 +/- 9% (mean +/- SD; n = 5) and 45 +/- 6% (n = 3), respectively. Thus, a heptaglucoside present in yeast cell walls is a unit ligand for human monocyte beta-glucan receptors.
An Auto-exposure algorithm for detecting high contrast lighting conditions (2007)

The proposed algorithm provides fast and accurate auto-exposure capability for digital still cameras. For normal lighting conditions, the number of preview frames and the exposure error are within 3.5 frames and 3.92%. For high contrast lighting conditions, the number of preview frames and the exposure error are within 8.8 frames and 6.56%. Furthermore, it offers accurate detection for both back lit and excessive front lit conditions at the same time and make proper exposure to the main object.
Ethnic minority development strategy (2003)

The objective of the Urban Upgrading Project for Vietnam is to eliminate hunger and reduce poverty in the urban areas by upgrading/improving the living conditions and environment of the poor people living in urban areas, using planning methods with the participation of communities. Social impacts resulting or coming from resettlement include: temporary use of land during construction; permanent land acquisition, households at edge of canal and entrances to alleyways; temporary and permanent impacts on shops and small businesses; relocation, transitional, household, and employment impacts in relocated households; and replacement of site infrastructure and social services. Mitigation measures include: a) minimize resettlement and land acquisition by considering and selecting most ultimate option; b) compensation, resettlement, and livelihood restoration programs should improve or at least maintain the living conditions of displaced persons (DPs) as those before the project and ensure their participation in the project; c) DPs must be supported adequately to be relocated with allowance for moving and other compensation with replacement price for affected house, land, and other assets; and d) effective and timely design, planning and implementation of resettlement options, and livelihood restoration measures must be carried out to avoid any unnecessary delays and disadvantages for DPs. Besides, internal and independent monitoring organizations must be arranged for all activities of resettlement.
High resolution distortion measurements of electron-beam transmission masks (1985)

Electron-beam proximity printing (EBP) is a step-and-repeat lithography technique which uses masks. Stringent requirement for submicron lithography is the capability to compensate for ever present linear and nonlinear mask distortions. We have demonstrated that a slight modification of the EBP system converts this into a high resolution mask metrology tool, i.e., enabled us to measure absolute distortions of our e-beam transmission mask in the EBP lithography tool itself. Resolution of these measurements was ±50 nm. Relative mask distortion data as deduced from our results coincided with separate experimental results from overlay experiments.
Compile-Time Enforcement of Dynamic Security Policies (2008)

Dynamic separation of duties, delegation and other dynamic security constraints require the state of the security system to be managed explicitly at run-time in software. The majority of this software is still programmed directly by humans, and is thus susceptible to errors that will impact the overall functionality and security of the system. In this paper we demonstrate a technique for statically checking properties of the software that manages dynamic security policies. We base our work on Kilim, a shared-nothing, message-passing Java framework that provides a faster, safer alternative to the dominant shared-memory and locking paradigm. We demonstrate that Kilim's static, compile- time verification of type linearity can also effect validation of aspects of dynamic security systems. We describe our initial steps toward the use of Kilim to support active, distributed security infrastructure.
El Índice Glucémico (GI) de los hidratos de carbono para deportistas (2007)

Geranylgeranyl diphosphate synthase (GGPS) catalyzes the biosynthesis of geranylgeranyl diphosphate, a key precursor for carotenoid biosynthesis. In this study, a full-length cDNA encoding GGPS from Dunaliella bardawil (DbGGPS) was isolated by rapid amplification of cDNA ends (RACE) for the first time. The full-length cDNA of DbGGPS was 1814 bp, containing a 1074 bp ORF encoding 357 amino acids with a calculated mass of 38.88 kDa. Analysis of DbGGPS genomic DNA revealed that it contained 10 exons and 9 introns. It was predicted that DbGGPS possessed a 48 amino acid transit peptide at its N terminus. Bioinformatic analysis revealed that DbGGPS was a member of a group of polyprenyltransferases with five conserved domains and two highly conserved aspartate-rich motifs. Using heterologous expression, carotenoid complementation assay, and gene deletion analysis, it was shown that the coding region of DbGGPS encodes a functional GGPS. This provides new gene sources for carotenoid genetic engineering.
Improvement of NO/sub X/ removal efficiency using short-width pulsed power (2000)

Pulsed power has been used to remove nitric oxide (NO) in a mixture of nitrogen, oxygen, and water vapor simulating the flue gases from a power station stack. The effect of the pulsewidth at a fixed applied voltage on NO removal concentration was studied. The dependence of the energy efficiency of the removal of NO at a fixed applied voltage on the pulsewidth, on the removal ratio of NO and on the discharge current was investigated. This removal energy efficiency increases with decreasing pulsewidth and decreasing removal ratio of NO.
Formation of L-methionine by methanol-utilizing bacteria. L-methionine overproduction by ethionine-resistant mutants of obligate methylotroph strain OM 33. (1982)

More than 400 methanol-utilizing microorganisms isolated from soil were examined for L-methionine excretion in methanol medium supplemented with L-homoserine as a precusor of L-methionine. The strain OM 33 excreted 70 μg/ml of L-methionine when L-homoserine (5 mg/ml) and Na2S•9H2O (2 mg/ml) were added to the medium. This strain utilized only methanol and monomethylamine as sole sources of carbon, and assimilated methanol via the ribulose monophosphate pathway. Ethionine-resistant mutants were induced from strain OM 33 by treatment with N-methyl-N'-nitro-N-nitrosoguanidine. A mutant, OE 120, excreted L-methionine into the medium without the addition of L-homoserine. Cultural conditions for L-methionine accumulation were investigated. After 4- to 5-days of cultivation, this mutant accumulated 420 μg/ml of L-methionine under optimum conditions.
Characterizing locality, evolution, and life span of accesses in enterprise media server workloads (2002)

The main issue we address in this paper is the workload analysis of today's enterprise media servers. This analysis aims to establish a set of properties specific for enterprise media server workloads and to compare them with well known related observations about web server workloads. We propose two new metrics to characterize the dynamics and evolution of the accesses, and the rate of change in the site access pattern, and illustrate them with the analysis of two different enterprise media server workloads collected over a significant period of time. Another goal of our workload analysis study is to develop a media server log analysis tool, called MediaMetrics, that produces a media server traffic access profile and its system resource usage in a way useful to service providers.
Effect of 2,4-diamino-6-hydroxy-pyrimidine on postburn Staphylococcus aureus sepsis in rats (2002)

Early treatment with DAHP might be a potential strategy to prevent the development of postburn Staphylococcal sepsis, which appears to be associated with down-regulation of biopterin and nitric oxide formation by DAHP.
Mono inverter dual parallel PMSM - structure and control strategy (2008)

This paper presents a dual parallel connected PMSM fed by a single power inverter. Both motors have to respect the synchronism even if they have different load torque. The rotor position of the two motors i.e. the load applied on each motor are consequently permanently compared. The motor with the highest load is set as the master one and is auto-piloted. The other one which has the same applied voltage has the same electric pulsation and so the same speed rotation. The change of the master choice is done whereas the load applied on the machine is changing so that oscillations appear during this change. The steady state is however rapidly attained and the synchronism stays always observed.

An Epidemic P2P Content Search Mechanism for Intermittently Connected Mobile Ad Hoc Networks (2009)

Abstract-Recently, popularity of multimedia content sharing among the Internet users and development of wireless mobile devices have promoted a trend of deploying Peer-to-Peer (P2P) networks over mobile ad hoc networks (MANETs) for mobile content distribution. However, due to limited radio transmission range, sporadic node densities and power limitations, MANETs may become intermittently connected thereby disrupting such mobile content distribution. Even though, various content delivery schemes have been proposed in the literature to resolve such underlying intermittent connectivity, another key issue for P2P content distribution networks i.e., how to search or lookup the interested contents in intermittently connected MANETs (ICMANs) context, is not investigated. With this in mind, this paper deploys a fully decentralized unstructured P2P network over ICMANs and accordingly introduces epidemic content search mechanism to discover the interested contents based on the related keywords. Note that the mobility and storage space of the mobile peers are exploited here to diffuse the content search requests. Moreover, to improve the efficiency under the restricted storage space conditions, a utility-based buffer management policy is presented. By evaluating each possible search request based on the relevant information such as mobility statistics, the requests with lower evaluated values are accordingly discarded when the buffer is full. Simulation results demonstrate the enhanced service performance offered by epidemic P2P content search scheme with utility-based buffer management policy.
Reactions of an Intramolecular Frustrated Lewis Pair with Unsaturated Substrates: Evidence for a Concerted Olefin Addition Reaction (2009)

The intramolecular frustrated Lewis pair (mesityl)(2)P-CH(2)-CH(2)-B(C(6)F(5))(2) was generated in situ by HB(C(6)F(5))(2) hydroboration of dimesitylvinylphosphine. The compound reacts with 1-pentyne by C-H bond cleavage. It undergoes a 1,2-addition to the carbonyl group of trans-cinnamic aldehyde to yield a zwitterionic six-membered heterocycle by B-O and P-C bond formation. The Lewis pair regioselectively adds to the electron-rich C=C double bond of ethyl vinyl ether, and it selectively undergoes an exo-cis-2,3-addition to norbornene. A combined experimental/theoretical study suggests that this reaction takes place in an asynchronous concerted fashion with the B-C bond being formed in slight preference to the P-C bond. The addition products were characterized by X-ray crystal structure analyses.
A programmable architecture for OFDM-CDMA (1999)

Combining multicarrier (OFDM) and CDMA technologies is attractive for future wireless broadband communications and software radio realization. Based on the unified framework known as OFCDMA, we develop a programmable structure for OFDM-CDMA transceivers in spite of three different scenarios to combine OFDM and CDMA. By adjusting system parameters without changing the fundamental hardware and software architecture, various system scenarios can be implemented, which might serve as the foundation to design software radio.
Comparison of image registration based measures of regional lung ventilation from dynamic spiral CT with Xe‐CT (2012)

Given a deformation field by an image registration algorithm, significant differences between the SAJ, SACJ, and SAI measures were found at a regional level compared to the Xe-CT sV in four sheep that were studied. The SACJ introduced here, provides better correlations with Xe-CT based sV than the SAJ and SAI measures, thus providing an improved surrogate for regional ventilation.
Universal portfolios with side information (1996)

We present a sequential investment algorithm, the /spl mu/-weighted universal portfolio with side information, which achieves, to first order in the exponent, the same wealth as the best side-information dependent investment strategy (the best state-constant rebalanced portfolio) determined in hindsight from observed market and side-information outcomes. This is an individual sequence result which shows the difference between the exponential growth wealth of the best state-constant rebalanced portfolio and the universal portfolio with side information is uniformly less than (d/(2n))log (n+1)+(k/n)log 2 for every stock market and side-information sequence and for all time n. Here d=k(m-1) is the number of degrees of freedom in the state-constant rebalanced portfolio with k states of side information and m stocks. The proof of this result establishes a close connection between universal investment and universal data compression.
A simple algorithm for partial redundancy elimination (1998)

Partial redundancy elimination was originally formulated as a bidirectional, bit-vector, data-flow analysis problem by Morel and Renvoise. Dhamdhere improved the original algorithm using the concept of edge placement. Knoop, R&amp;uuml;thing, and Steffen viewed the problem within a framework that required only four unidirectional analyses for an optimal solution. Here, we propose an algorithm for partial redundancy elimination based on well known concepts, viz., availability, anticipability, partial availability, and partial anticipability. The algorithm is both computationally and lifetime optimal. Our algorithm also requires four unidirectional data-flow analyses. The main advantage of the algorithm is its simplicity.
Harmonizing textual and graphical visualizations of domain specific models (2013)

Domain-specific models, and the modeling languages that support them, have played a central role in the success of model-driven development and its ability to bridge the abstraction gap between software implementation technologies and human developers. However, the current generation of domain-specific modeling tools is firmly split into two camps --- those that support textual domain-specific languages and those that support graphical domain-specific languages. Both camps have enjoyed significant success, but at the time of writing no mainstream tool supports both at the same time. This stops developers from swapping freely between textual and graphical visualizations of a given subject of interest, even if each form has clear advantages and/or disadvantages for different stakeholders. In this paper we present an environment which offers a solution to this problem by strictly separating concerns for notation (i.e. concrete syntax) and concerns for concepts (i.e. abstract syntax) and allowing them to be connected and mixed dynamically as required.

Written by one of the world's leading information theorists, evolving over twenty years of graduate classroom teaching and enriched by over 300 exercises, this is an exceptional resource for anyone looking to develop their understanding of stochastic processes.
Differentiation of Biologic Scaffold Materials Through Physicomechanical, Thermal, and Enzymatic Degradation Techniques (2012)

Although differences were observed because of cross-linking, some crosslinked and non-crosslinked materials exhibited very similar properties. Variables other than cross-linking, such as decellularization/sterilization treatments or species/tissue type also contribute to the properties of the scaffolds.
Nonlinear dynamics of nanomechanical beam resonators: improving the performance of NEMS-based sensors (2009)

In order to compensate for the loss of performance when scaling resonant sensors down to NEMS, it proves extremely useful to study the behavior of resonators up to very high displacements and hence high nonlinearities. This work describes a comprehensive nonlinear multiphysics model based on the Euler-Bernoulli equation which includes both mechanical and electrostatic nonlinearities valid up to displacements comparable to the gap in the case of an electrostatically actuated doubly clamped beam. Moreover, the model takes into account the fringing field effects, significant for thin resonators. The model has been compared to both numerical integrations and electrical measurements of devices fabricated on 200 mm SOI wafers; it shows very good agreement with both. An important contribution of this work is the provision for closed-form expressions of the critical amplitude and the pull-in domain initiation amplitude including all nonlinearities. This model allows designers to cancel out nonlinearities by tuning some design parameters and thus gives the possibility to drive the resonator beyond its critical amplitude. Consequently, the sensor performance can be enhanced to the maximum below the pull-in instability, while keeping a linear behavior.
An architecture for covert channel control in realtime networks and multiprocessors (2002)

The paper discusses a system architecture for controlling covert channels in multilevel real-time networks and multiprocessor systems. The concept is derived from a popular (non-secure) real-time architecture I refer to as a foreground/background system. I address the covert channel (confinement) problem in the real-time foreground. Covert channel control within this system architecture rests on two properties: (I) a fairly strong nondisclosure properly called "elastic separability"; (2) "systolic", or phase-delayed timing of real-time system input-output with non-preemptive scheduling. The architecture is thus called a "systolic elastically separable" (SES) real-time network. SES networks satisfy a security property called "weak confinement". Total security (called "strong confinement") can be achieved in any SES real-time network by making simple timing adjustments at external interfaces.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Chronic venous access: bedside placement technique and complications. (1995)

Long-term tunneled venous access catheters have evolved into safe and useful tools. More than 80% of these are implanted in patients in operating rooms with fluoroscopic and anesthesia support. This article describes a technique for safely placing these catheters at the patient's bedside and focuses on how to identify, prevent, and manage common complications associated with this procedure. This article also summarizes 8 years of the authors' personal experience with bedside placement and describes a hospital quality assurance study that evaluated the efficacy of bedside placement. The role of appropriately trained personnel is highlighted. The possibility of cost savings, totaling millions of dollars, is raised.
