Chromium speciation analysis by solid-phase extraction on a high surface area TiO2 (2000)

The adsorption of Cr3+ and Cr6+ on different metal oxides (MgO, Al2O3, TiO2, ZrO2 and CeO2) with high specific surface areas was studied under different conditions. It was established that SiO2 can be used for selective and quantitative adsorption of Cr3+, whereas, depending on the pH, TiO2 and Al2O3 can selectively adsorb Cr3+ or Cr6+. On the basis of the results obtained, a simple and sensitive method for the selective determination of Cr3+ and Cr6+ in natural water samples using a column solid-phase extraction on a high surface area TiO2 (anatase) was developed. The conditions for quantitative and reproducible preconcentration, elution and subsequent ETAAS determination were established. The retention efficiency is better than 95% for Cr3+ and Cr6+, giving a sensitivity enhancement of 100 for a 100 ml sample volume. The proposed method is characterized by high precision and high reproducibility. The detection limit based on the 3ς criterion is 30 ng l−1 for Cr3+ and 24 ng l−1 for Cr6+.
Bidirectional Correlation of NMR and Capillary Electrophoresis Fingerprints: A New Approach to Investigating<i>Schistosoma mansoni</i>Infection in a Mouse Model (2009)

We demonstrate the statistical integration of nuclear magnetic resonance (NMR) spectroscopy and capillary electrophoresis (CE) data in order to describe a pathological state caused by Schistosoma mansoni infection in a mouse model based on urinary metabolite profiles. Urine samples from mice 53 days post infection with S. mansoni and matched controls were analyzed via NMR spectroscopy and CE. The two sets of metabolic profiles were first processed and analyzed independently and were subsequently integrated using statistical correlation methods in order to facilitate cross assignment of metabolites. Using this approach, metabolites such as 3-ureidopropionate, p-cresol glucuronide, phenylacetylglycine, indoxyl sulfate, isocitrate, and trimethylamine were identified as differentiating between infected and control animals. These correlation analyses facilitated structural elucidation using the identification power of one technique to enhance and validate the other, but also highlighted the enhanced ability to detect functional correlations between metabolites, thereby providing potential for achieving deeper mechanistic insight into the biological process.
Fast generation of prime numbers and secure public-key cryptographic parameters (1993)

A very efficient recursive algorithm for generating nearly random provable primes is presented. The expected time for generating a prime is only slightly greater than the expected time required for generating a pseudoprime of the same size that passes the Miller-Rabin test for only one base. Therefore our algorithm is even faster than algorithms presently used for generating only pseudoprimes because several Miller-Rabin tests with independent bases must be applied for achieving a sufficient confidence level. Heuristic arguments suggest that the generated primes are close to uniformly distributed over the set of primes in the specified interval.

Security constraints on the prime parameters of certain cryptographic systems are discussed, and in particular a detailed analysis of the iterated encryption attack on the RSA public-key cryptosystem is presented. The prime-generation algorithm can easily be modified to generate nearly random primes or RSA-moduli that satisfy these security constraints. Further results described in this paper include an analysis of the optimal upper bound for trial division in the Miller-Rabin test as well as an analysis of the distribution of the number of bits of the smaller prime factor of a random k-bit RSA-modulus, given a security bound on the size of the two primes.
Integrating pathology and radiology disciplines: an emerging opportunity? (2012)

Pathology and radiology form the core of cancer diagnosis, yet the workflows of both specialties remain ad hoc and occur in separate "silos," with no direct linkage between their case accessioning and/or reporting systems, even when both departments belong to the same host institution. Because both radiologists' and pathologists' data are essential to making correct diagnoses and appropriate patient management and treatment decisions, this isolation of radiology and pathology workflows can be detrimental to the quality and outcomes of patient care. These detrimental effects underscore the need for pathology and radiology workflow integration and for systems that facilitate the synthesis of all data produced by both specialties. With the enormous technological advances currently occurring in both fields, the opportunity has emerged to develop an integrated diagnostic reporting system that supports both specialties and, therefore, improves the overall quality of patient care.
Multimedia news digger on emerging topics from social streams (2012)

With the overwhelming information from social media networks and news portals, it is crucial to provide users a complete package of visual and textual information with popular interests automatically. To this concern, we present a news detection and pushing system, called Me-Digger (Multimedia News Digger), which not only effectively detects emerging topics from social streams but also provides the corresponding information in multiple modalities. Me-digger is the first systematic effort to leverage three sources of data, that is, Twitter, Flickr and Google news, to output with vivid visual and textual contents on emerging topics. Enabled by a novel general-structured high-order co-clustering approach, it has a more accurate detection of emerging topics compared to the existing methods on micro-blog social streams.
Unilateral Transforaminal Posterior Lumbar Interbody Fusion (2002)

A prospective analysis of consecutive patients who had lumbar fusion using the unilateral transforaminal posterior lumbar interbody fusion with pedicle screw fixation is presented to assess the clinical and radiographic outcomes of the transforaminal posterior lumbar interbody fusion procedure and describe the technique and indication in the treatment of degenerative disease of the lumbar spine. Forty patients treated with transforaminal posterior lumbar interbody fusion for degenerative diseases of the lumbar spine (with anterior column deficiency) were followed up for a minimum of 3 years (mean, 3.4 years; range, 3-3.9 years). Radiographic assessment included plain and flexion and extension radiographs. Clinical outcome was based on pain relief, ability to do activities of daily living, and return to work. Thirty-six patients (90%) had solid fusions and at latest followup, segmental lordosis has increased in all patients. Eighty-five percent of patients had excellent or good clinical outcome(s). The unilateral transforaminal posterior lumbar interbody fusion provides bilateral anterior column support through a unilateral approach. The patients had high fusion rates and patient satisfaction as reported with similar complications found in other methods commonly used for spinal decompression and stabilization.
High speed SOI buffer circuit with the efficient connection of subsidiary MOSFETs for dynamic threshold control (2002)

Summary form only given. We propose a new non-inverting SOI buffer circuit adopting dynamic body bias control via subsidiary MOSFETs connected efficiently to obtain high speed at low supply voltage. Device simulation has been performed to show current derivability of body controlled devices. Delay time characteristics of the buffer circuit were analyzed by SPICE simulation and compared with those of SOI CMOS buffer circuit. Delay time reduction of the SOI buffer circuit over conventional SOI CMOS buffer circuit with same area is about 36% at V/sub s/=1.2 V and C/sub L/=2 pF.

Method for the calculation of partially coherent imagery (1978)

The tedious numerical computations associated with the calculation of partially coherent imagery are alleviated by a method which uses dimensionless coordinates and takes advantage of the properties of the Fourier transform. A 1-D periodic object function can model many objects of practical interest, including nonperiodic objects. The properties of a given optical system are described in terms of the transmission cross coefficient. For aberration-free systems with circular pupils, including annular sources (dark-field illumination), the cross coefficient can be calculated analytically. For aberrated or apodized systems, a 1-D approximation can be used. The effect of a convolving slit in the image plane of a scanning microscope can also be included.
Integrated management of cooling resources in air-cooled data centers (2010)

To accommodate the dynamic environment within raised floor data centers, cooling capacity is tuned during operation through zonal control means, e.g., active management of air conditioning resources. However, due to the spatial variance of cooling efficiency and time-varying cooling demand within zones, zonal adjustments alone are not able to maximize the thermal capacity of data centers. Without making local adjustments to the physical structure, such as altering vent tile openings, a data center can suffer significant reduction in thermal capacity and cooling efficiency, and such that facility lifespan. In this paper, we present active cooling technologies using both local and zonal actuators that improve overall cooling efficiency. Experimental evaluation in a data center shows that the integrated controller can adapt to changes to the system under control, significantly improve the controllability of the temperatures and reduce the energy consumption of the cooling facility.
Models from experiments: combinatorial drug perturbations of cancer cells (2008)

We present a novel method for deriving network models from molecular profiles of perturbed cellular systems. The network models aim to predict quantitative outcomes of combinatorial perturbations, such as drug pair treatments or multiple genetic alterations. Mathematically, we represent the system by a set of nodes, representing molecular concentrations or cellular processes, a perturbation vector and an interaction matrix. After perturbation, the system evolves in time according to differential equations with built-in nonlinearity, similar to Hopfield networks, capable of representing epistasis and saturation effects. For a particular set of experiments, we derive the interaction matrix by minimizing a composite error function, aiming at accuracy of prediction and simplicity of network structure. To evaluate the predictive potential of the method, we performed 21 drug pair treatment experiments in a human breast cancer cell line (MCF7) with observation of phospho-proteins and cell cycle markers. The best derived network model rediscovered known interactions and contained interesting predictions. Possible applications include the discovery of regulatory interactions, the design of targeted combination therapies and the engineering of molecular biological networks.
Impact of annealing on morphology and thermal stability of Bi<sub>2</sub>O<sub>3</sub> nanotube‐based microarchitectures (2012)

Abstract Bi 2 O 3 nanostructures with high surface‐to‐volume ratio are attracting particular interest in catalysis, gas sensors, solar‐energy conversion, and so on. In this paper, we present the impact of annealing on morphology, structure, and optical properties of Bi 2 O 3 nanotube‐based urchin‐like microarchitectures, which is very important to determine before their applications in many potential fields. Our results showed that below 400 °C, the microarchitectures possessed good thermal stability. While annealing at 500 °C, jointed nanoparticles with an average size of 350 nm were formed. On further increasing the annealing temperature to 600 °C, the microarchitectures were transformed into stable α‐Bi 2 O 3 microcrystal film with a larger particle size of about 800 nm. The optical bandgaps of the annealed products were also changed according to their changes of morphology and structure.
A new PVD sputtering source for metal gate application (2006)

A new PVD source for metal gate applications has been systematically characterized. Results from the study indicate that the new source provides very low trap density (<1 times 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sup> /cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> eV), excellent film thickness (and sheet resistance) non-uniformity (<1% 1sigma) and a wide range in deposition rates (from 0.4 Aring/s to 6 Aring/s), making it suitable for depositing metal films directly on gate oxides in 45nm and 32nm technology nodes
Synthesis and Self-Organization of Core-Extended Perylene Tetracarboxdiimides with Branched Alkyl Substituents (2006)

The influence of the core extension of perylene tetracarboxdiimides on the thermotropic behavior has been investigated. A homologous series of alkyl substituted tetracarboxdiimides, namely, perylene diimide, terrylene diimide, quaterrylene diimide, and coronene diimide, was synthesized. These compounds display absorption maxima in the region of 430−760 nm with high extinction coefficients and show a high thermal stability up to 450 °C. Structural evaluation revealed an identical columnar self-organization for the derivatives below their isotropization temperature. An intracolumnar packing of the disks with a lateral rotation of 45° to each other resulted in a helical pitch containing four molecules. The phase transition to the isotropic phase is shifted to higher temperatures for larger aromatic cores within this series of compounds. On the other hand, differences in the self-assembly during crystallization from the isotropic phase were observed. While perylene tetracarboxdiimide and terrylene tetracarboxdiimide formed large and highly ordered domains with arranged edge-on molecules, the coronene tetracarboxdiimide disks self-organized face-on leading to a homeotropic phase. The different molecular orientation on surfaces was correlated with diversified substitution patterns of the aromatic cores. The manipulation of the molecular architecture opens thus the opportunity to control the spontaneous self-alignment. This improvement of the macroscopic organization ensures an undisturbed percolation pathway for charge carriers between electrodes in field-effect transistors or in photovoltaic cells.
Poly n-butylcyanoacrylate (PNBCA) nanocapsules as a carrier for NSAIDs: in vitro release and in vivo skin penetration. (2003)

The presented data show that indomethacin loaded PNBCA nanocapsules can improve the transdermal delivery of indomethacin compared to a conventional gel formulation using Pluronic F-127. This might be due to their ultra fine particle size and their hydrophilic and hydrophobic surface characteristics.

Tunnel diodes fabricated from CdSe nanocrystal monolayers (1999)

A parallel approach for fabricating nanocrystal-based semiconductor–insulator–metal tunnel diodes is presented. The devices consisted of a Au electrode, a monolayer of 38 Å CdSe nanocrystals, an insulating bilayer of eicosanoic acid (C19H39CO2H), and an Al electrode. Each device was approximately 100 μm2. Conductance measurements at 77 K reveal strong diode behavior and evidence of Coulomb blockade and staircase structure. A single barrier model was found to reproduce the electronic characteristics of these devices.
Computerized Continuous Infusion of Intravenous Anesthetic Drugs During Pediatric Cardiac Surgery (1991)

We evaluated the efficacy of a computer-assisted continuous infusion device (CACI) using a two-drug infusion of midazolam and sufentanil as an anesthetic technique during pediatric cardiac surgery. Seventeen pediatric patients were anesthetized with CACI using age-appropriate pharmacokinetic models for administering sufentanil and midazolam. Predicted CACI plasma concentrations were correlated with assayed plasma drug concentrations at eight predefined intervals. The accuracy was assessed using median absolute prediction error. We found that plasma levels predicted by CACI provided a reasonable approximation of measured plasma concentrations for both drugs. The median absolute prediction error for sufentanil during cardiopulmonary bypass was compared with measurements made off of cardiopulmonary bypass (both pre and post cardiopulmonary bypass) and were 49% and 32%, respectively, and for midazolam 44% and 32%, respectively. We conclude that (a) current kinetic models provide a reasonable estimate of plasma drug concentrations, and (b) the ease of administration and targeted plasma level provided by the CACI system is an alternative to inhalation anesthesia using calibrated vaporizers.

Retentive Memory of Bacteria: Long-Term Regulation of Dehalorespiration in <i>Sulfurospirillum multivorans</i> (2008)

The gram-negative, strictly anaerobic epsilonproteobacterium Sulfurospirillum multivorans is able to gain energy from dehalorespiration with tetrachloroethene (perchloroethylene [PCE]) as a terminal electron acceptor. The organism can also utilize fumarate as an electron acceptor. Prolonged subcultivation of S. multivorans in the absence of PCE with pyruvate as an electron donor and fumarate as an electron acceptor resulted in a decrease of PCE dehalogenase (PceA) activity. Concomitantly, the pceA transcript level equally decreased as shown by reverse transcriptase PCR. After 35 subcultivations (approximately 105 generations), a pceA transcript was not detectable and the PceA protein and activity were completely absent. In such long-term subcultivated S. multivorans cells, the biosynthesis of catalytically active PceA was restored to the initial level within about 50 h (approximately three generations) by the addition of PCE or trichloroethene. Single colonies obtained from PceA-depleted cultures were able to induce PCE dechlorination, indicating that long-term subcultured cells still contained the functional pceA gene. The results point to a novel type of long-term regulation of PCE dehalogenase gene expression in S. multivorans.
Evolution of naturally occurring 5'non-coding region variants of Hepatitis C virus in human populations of the South American region (2007)

Phylogentic analysis revealed the presence of a sequence signature in the 5'NCR of type 1 HCV strains isolated in South America. This signature is frequent enough in type 1 HCV populations circulating South America to be detected in a phylogenetic tree analysis as a distinct type 1 sub-population. The coexistence of distinct type 1 HCV subpopulations is consistent with quasispecies dynamics, and suggests that multiple coexisting subpopulations may allow the virus to adapt to its human host populations.
효과적인 품질분임조활동의 단계별 진행요령에 관한 연구 (2003)

The purpose of this paper is to propose the effective guidance of Quality Circle(QC) activities. Since 1975, variety of organizations in Korea have widely implemented QC activities for their management systems. The industries have enthusiastically used QC activities and were influenced from them. However, the academics were less interested in this subject, as a result, there were no systematic guidances for QC activities. Thus, jn this paper, the effective guidance for QC activities were suggested which were based on the survey from QC proceedings presented in the companies, in the local areas and the national wide contests. As a result. the first main issue is to pick repeated mistakes up during the process period such a s unmatched the causes and effects relations in characteristics diagrams. improper selection of important control items in Pareto diagram and so on. Secondly, how to overcome statistics and use them for QC activities. Thirdly, to remind team members about Quality Control 7 tools. Finally, Minitab(Release-13) software has been found that it is not matched with using Korean StandarddKS).

Phosphor: Illuminating Dynamic Data Flow in the JVM (2014)

Dynamic taint analysis is a well-known information flow analysis problem with many possible applications. Taint tracking allows for analysis of application data flow by assigning labels to inputs, and then propagating those labels through data flow. Taint tracking systems traditionally compromise among performance, precision, accuracy, and portability. Performance can be critical, as these systems are typically intended to be deployed with software, and hence must have low overhead. To be deployed in security-conscious settings, taint tracking must also be accurate and precise. Dynamic taint tracking must be portable in order to be easily deployed and adopted for real world purposes, without requiring recompilation of the operating system or language interpreter, and without requiring access to application source code. We present Phosphor, a dynamic taint tracking system for the Java Virtual Machine (JVM) that simultaneously achieves our goals of performance, accuracy, precision, and portability. Moreover, to our knowledge, it is the first portable general purpose taint tracking system for the JVM. We evaluated Phosphor's performance on two commonly used JVM languages (Java and Scala), on two versions of two commonly used JVMs (Oracle's HotSpot and OpenJDK's IcedTea) and on Android's Dalvik Virtual Machine, finding its performance to be impressive: as low as 3% (53% on average), using the DaCapo macro benchmark suite. This paper describes the approach that Phosphor uses to achieve portable taint tracking in the JVM.
