Neurocysticercosis in an Orthodox Jewish Community in New York City (1992)

A diagnosis of neurocysticercosis should be considered in patients with seizures and radiologic evidence of cystic brain lesions, even in those who do not eat pork and who have not traveled to a country in which T. solium infection is endemic. Recent emigrants from countries in which T. solium infection is endemic should be screened for tapeworm infection in their stools before they are employed as housekeepers or food handlers.
Analysis of omni-directional views at different location (2002)

Omni-directional views of environment are analyzed to build a world model of an autonomous mobile robot. A panoramic view is yielded by arranging the vertical line at the center of each image taken by a camera attached on the robot. The panoramic view is featured by the cylindrical projection of a 3D line onto a sinusoidal curve. The following three issues are discussed: (1) projection of 3-D space onto the panoramic view; (2) epipolar curves for stereo matching; and (3) optical flow. A method for finding the 3D structure of an environment is proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Caching Strategies for Data-Intensive Web Sites (2000)

Data-intensive Web sites serve large volumes of pages whose content is dynamically extracted from a database. Such Web sites have very high software development and maintenance costs and in general oer poor response times due to the heavy interaction with the database system. This paper introduces the Weave management system de-veloped at INRIA, which alleviates the above shortcomings of data-intensive Web sites. Weave relies on the declara-tive specication of Web sites and oers a number of tools for the easy implementation, deployment and monitoring of the specied site. Weave features a customizable cache system that implements the optimal data materialization strategy according to the Web site&apos;s specics: it can cache database data, XML fragments and HTML les. To ex-plore Weave&apos;s performance we have built a Web site based on the TPC/D benchmark database using the WeaveBench test platform. We conducted a number of experiments with various data materialization strategies supported by our system. Results clearly show that in the general case, a mix of dierent caching policies is required to achieve op-timal performance. 1
Exploitation of silicon medicinal chemistry in drug discovery (2004)

There remains considerable pressure on the pharmaceutical industry to increase productivity and reduce the attrition of drug candidates. Genomics, parallel chemistry and high-throughput biology have not yielded the anticipated benefits, resulting in a renewed focus on validated targets and an aim to generate drugs directed towards such targets, which have a clear advantage. One strategy to identify and develop best-in-class drugs is to apply a high degree of innovation in chemistry and apply this to targets from gene families that have been clinically validated as tractable and drugable. The application of organosilicon medicinal chemistry in the context of privileged structures to aid drug design and development is one such innovative approach that is reviewed in this paper.
Estimates for practical quantum cryptography (1999)

In this paper I present a protocol for quantum cryptography which is secure against attacks on individual signals. It is based on the Bennett-Brassard protocol of 1984. The security proof is complete as far as the use of single photons as signal states is concerned. Emphasis is placed on the practicability of the resulting protocol. For each run of the quantum key distribution the security statement gives the probability of a successful key generation and the probability for an eavesdropper's knowledge, measured as change in Shannon entropy, to be below a specified maximal value.

Heat and mass transport in microwave drying of porous materials in a spouted bed (2001)

Abstract A heat‐ and mass‐transfer model was developed to simulate microwave and spouted‐bed combined (MWSB) drying of diced apples, a hygroscopic porous material. A total gas‐pressure equation was introduced to take into account internal vapor generation during microwave drying. The governing equations for heat and mass transfer were simplified using a scaling technique and numerically solved with the finite difference method. The physical, thermodynamic, thermal, transport and dielectric properties used in the simulation were either from our measurements or from the literature. Model predictions agreed well with experimental results. The pressure‐driven moisture migration during MWSB drying resulted in a high drying rate. The numerical analysis predicted a temperature‐leveling effect that was confirmed by experimental results. The unique temperature leveling in MWSB drying helps to control product temperature and improves product quality as compared to microwave‐assisted fixed‐bed hot‐air drying methods.
Solder joint reliability of flip chip and plastic ball grid array assemblies under thermal, mechanical, and vibration conditions (2002)

The thermal, mechanical and vibration responses of flip chip and PBGA (Plastic Ball Grid Array) solder joints have been determined in this study. The effects of overload environmental stress factors on the mechanical responses of the solder joints have been determined by bending and twisting experiments. The effects of shipping environmental stress factors on the vibration responses of the solder joints have been determined by out of plane vibration experiments. Also, the thermal fatigue behavior of solder joints have been investigated by nonlinear finite element, Coffin-Manson, and fracture mechanics methods.
Design, Synthesis, and Biological Evaluation of New Cyclic Melanotropin Peptide Analogues Selective for the Human Melanocortin-4 Receptor (2006)

Intensive efforts have been made to develop potent and selective ligands for certain human melanocortin receptors as possible treatments for obesity and sexual dysfunction due to the role of these receptors in feeding behavior, energy homeostasis, sexual function, etc. A number of novel alpha-MSH analogues were designed and synthesized primarily on the basis of our previous MTII NMR structure. In these peptide analogues, a disulfide or lactam bridge between residues at positions 5 and 8 was used as a conformational constraint to enhance the beta-turn spanning His6 and D-Phe7, while the pharmacophore group in Arg8 was mimicked via Nalpha-alkylation of residues 8 or 9 with the guanidinylbutyl group. Biological assays for binding affinities and adenylate cyclase activities for the hMC1R, hMC3R, hMC4R, and hMC5R showed that three analogues have good binding affinity for the hMC4R (0.7-4.1 nM), but have no binding affinity up to 10 microM at the other three melanocortin receptors. Interestingly, the three hMC4R selective analogues display only 50% binding efficiency, suggesting there is allosteric modulation of the melanocortin-4 receptor. These analogues were found to act as antagonists of the hMC4R. This result represents a discovery of very selective peptide-based antagonists for the hMC4R. The high selectivity may be due to the strong conformational constraint via ring contraction as compared to MTII, and the rigid conformation preferred by these new ligands allows them to recognize only the hMC4R, but not to activate the second messenger. The MTII NMR structure-based design thus not only examined the structural model of melanocortin ligands, but also yielded new biologically unique alpha-MSH analogues.
Finite element design of a new piezoelectricity bender disk transducer array (2010)

Low frequency, broadband, small size and high power is main direction for underwater acoustic transducers. A new piezoelectricity bender disk transducer is firstly designed with finite element method, which is element of an array that can realize low frequency, small size, high power and directivity, but with narrow bandwidth. Then different dimension bender disk transducer elements are assembled together to a tightness arrangement vertical array, analyzing with finite element method. With driving pattern of piezoelectric ceramics designed, the array can achieve broadband transmitting, simultaneously, maintaining other advantages, and the transmitting voltage response exceeds 135 dB. In this way, a low frequency, broadband and small size underwater acoustic transducer array which can also transmits with high power is designed, owning broad prospects and applied value.
Inhibitory Effect of Cladosiphon Fucoidan on the Adhesion of Helicobacter pylori to Human Gastric Cells. (1999)

We studied the inhibitory effect of Cladosiphon fucoidan on the attachment of Helicobacter pylori (H. pylori), a gastroduodenal pathogen, to human gastric cell lines. The bacterial binding in these cell lines was inhibited more by Cladosiphon fucoidan (IC50 = 16-30 mg/mL), than by the fucoidan from Fucus (IC50 > 30 mg/mL). Dextran sulfate, another sulfated polysaccharide, did not inhibit the binding at all. Pre-incubating the bacterial suspension with fucoidans reinforced the inhibitory ability of these components, and reduced the IC50 value of Cladosiphon fucoidan to approximately 1 mg/mL. However, the binding was not inhibited by pre-treatment of gastric cells with these components. It was also shown that this fucoidan blocks both Leb- and sulfatide-mediated attachment of H. pylori to gastric cells. Furthermore, fucoidan-binding proteins were found on the H. pylori cell surface by Western blot analysis. Thus, the inhibitory effect exerted by Cladosiphon fucoidan on binding between H. pylori and gastric cells might result from the coating with this component of the bacterial surface.
Chronic atrophic gastritis and Helicobacter pylori infection in primary biliary cirrhosis: a cross-sectional study with matching. (1997)

PBC patients are not characterized by chronic atrophic gastritis. Even though they present chronic gastritis with the same prevalence as dyspeptic controls, and show signs of previous H. pylori infection as frequently as dyspeptic patients, they are actually much less frequently infected. The reasons for this observation are unclear.
A radar cross-section model for power lines at millimeter-wave frequencies (2003)

The knowledge of radar backscatter characteristics of high-voltage power lines is of great importance in the development of a millimeter-wave wire detection system. In this paper, a very high-frequency technique based on an iterative physical optics approach is developed for predicting polarimetric radar backscattering behavior of power lines of arbitrary strand arrangement. In the proposed scattering model the induced surface current is obtained using the tangent plane approximation in an iterative manner where the first-order current, obtained from the incident wave, is used as the source for the second-order current and so on. The approximation is valid for frequencies where the cable strand diameter is on the order of or larger than the wavelength. It is shown that the copolarized backscatter is dominated by the contribution from the first-order PO currents, whereas the cross-polarized backscatter is generated by the second- and higher order PO currents. Using this model, the effects of radar antenna footprint, surface irregularities, and cable sag (when suspended between towers) on radar backscatter are studied. To verify the validity of the proposed model, theoretical results are compared at 94 GHz with experimental results and are found to be in good agreement.
Treatment of meniscal tears: An evidence based approach (2014)

Treatment options for meniscal tears fall into three broad categories; non-operative, meniscectomy or meniscal repair. Selecting the most appropriate treatment for a given patient involves both patient factors (e.g., age, co-morbidities and compliance) and tear characteristics (e.g., location of tear/age/reducibility of tear). There is evidence suggesting that degenerative tears in older patients without mechanical symptoms can be effectively treated non-operatively with a structured physical therapy programme as a first line. Even if these patients later require meniscectomy they will still achieve similar functional outcomes than if they had initially been treated surgically. Partial meniscectomy is suitable for symptomatic tears not amenable to repair, and can still preserve meniscal function especially when the peripheral meniscal rim is intact. Meniscal repair shows 80% success at 2 years and is more suitable in younger patients with reducible tears that are peripheral (e.g., nearer the capsular attachment) and horizontal or longitudinal in nature. However, careful patient selection and repair technique is required with good compliance to post-operative rehabilitation, which often consists of bracing and non-weight bearing for 4-6 wk.
Experimental evaluation of a new type of heparin-bonded polyurethane. (1992)

A new type of heparin bonding method using polyurethane (H-PU) in an ionically equivalent manner was examined experimentally. In vitro testing of polyvinylchloride tubes with this coating showed that the behavior of the heparin was attributed to the activation of retained heparin on the surface. After 4 hrs of heparinless arterio-arterial bypass in a canine model with a central shear rate of 25 sec-1 (inner diameter, 0.8 x 80 cm), macroscopic and scanning electron microscopic examinations showed that the H-PU coated tube had better antithrombogenicity than that of a conventional PU coated tube (Pellethane). These results suggest that this heparin bonding method with PU appears to have good antithrombogenicity with possible long durability.
Isotropic elastic reverse time migration using the phase- and amplitude-corrected vector P- and S-wavefields (2018)

In elastic reverse time migration (RTM), wavefield separation is an important step to remove crosstalk artifacts and improve imaging quality. State-of-the-art techniques for wavefield separation in isotropic elastic media include using the Helmholtz decomposition and introducing an auxiliary wave equation. Although these two approaches produce pure-mode vector wavefields with correct amplitudes, phases, and physical units, their computational costs are still high under current computational capability, especially for 3D large-scale problems. Based on the P- and S-wave dispersion relations, we have developed an efficient wavefield separation strategy for elastic RTM. Instead of solving a vector Poisson’s equation in the Helmholtz decomposition, we modify the phases of source wavelet as well as multicomponent records and scale the amplitudes of extrapolated wavefields with the squares of P- and S-wave velocities. This operation allows us to produce vector P- and S-wavefields with the same phases and amplitudes as the input coupled wavefields while significantly reducing computational costs. With the separated vector wavefields, we implemented a modified dot-product imaging condition for elastic RTM. In comparison with the previously proposed dot-product imaging condition, this modified imaging condition enables us to eliminate the effects of multiplication with a cosine function and hence produces migrated images with accurate amplitudes. Several 2D and 3D numerical examples are used to demonstrate the feasibility and robustness of our method for imaging complex subsurface structures.
Dynamic discharge and performance of a new adsorbent for natural gas storage (2001)

Abstract Performance of a new highly conductive adsorbent matrix for ANG systems was evaluated. The adsorbent composite block (ACB) was a mixture of superactivated carbon, labeled MAXSORB and expanded natural graphite (ENG), followed by consolidation. ENG was used both as a very high conductive matrix and as support for adsorbents. Thermal conductivity is 30 times higher than that of activated carbon packed bed. Dynamic methane discharges were studied experimentally with a 2‐L vessel filled with ACB. The influence of both the discharge flow rate and heat‐exchange conditions at the reactor wall on the delivered methane capacity was investigated. The modeling of the discharge process, validated from experimental results, shows the efficiency of this ACB with a 100‐V/V delivered methane capacity under various working conditions.
Structure and in Vitro Molecular Chaperone Activity of Cytosolic Small Heat Shock Proteins from Pea (1995)

Plants synthesize several classes of small heat shock proteins ranging in size from 15 to 30 kDa. Two conserved classes, designated class I and class II, are localized to the cytosol. Recombinant HSP18.1 and HSP17.7, representing class I and class II proteins from pea, respectively, were expressed in Escherichia coli and purified. Non-denaturing polyacrylamide gel electrophoresis and electron microscopy demonstrated that the purified proteins formed discretely sized, high molecular weight complexes. Sedimentation equilibrium analytical ultracentrifugation revealed that the HSP18.1 and HSP17.7 complexes were composed of approximately 12 subunits. Both proteins were able to enhance the refolding of chemically denatured citrate synthase and lactate dehydrogenase at stoichiometric levels in an ATP-independent manner. Furthermore, HSP18.1 and HSP17.7 prevented aggregation of citrate synthase at 45 degrees C and irreversible inactivation of citrate synthase at 38 degrees C. HSP18.1 also suppressed aggregation of lactate dehydrogenase at 55 degrees C. These findings demonstrate that HSP18.1 and HSP17.7 can function as molecular chaperones in vitro.
Freiwillige Leistungen als Objekte betrieblicher Anreizgestaltung und ihre Integration in die Personal- und Produktionsplanung (2005)

gabe darin, dysfunktionale Einsatze weicher HR-Kennzahlen zu erkennen und deren Entstehung vorzubeugen. Ein weiterer relevanter Schritt in Richtung eines solchen nachhaltigen Personalmanagements ist die systematische Bezugnahme und Verknup fung weicher HR-Kennzahlen mit wichtigen Steuerungsund Anreizsystemen im Kontext der gegebenen Unternehmensstrategie. Unter der Voraussetzung, dass die bestehenden Probleme uberwunden werden, konnten die Vorteile einer systemati schen Einbindung weicher HR-Kennzahlen in die Personalsteuerung, insbesondere vor dem Hintergrund der zunehmenden Bedeutung solcher Grosen, enorm sein.
Properties of magnetic vortices at elevated temperatures (2013)

Thermal properties of steady-state magnetic vortices in soft materials are numerically evaluated using the recently proposed Landau-Lifshitz-Bloch approach. Circular samples with permalloy-like parameters are simulated. Relevant properties of the vortex core, as its radius, the magnetization drop in its center, and the radius of this magnetization drop are extracted. The dependence of the vortex core radius on temperature agrees well with the theoretical predictions, if only temperature-dependent parameters are taken into account. A new effect is found, which we call magnetization squeezing, resulting from the thermodynamic nature of the Landau-Lifshitz-Bloch approach. Our results show, however, that this squeezing in vortices is a rather weak effect in permalloy.
Co-localisation and secretion of glucagon-like peptide 1 and peptide YY from primary cultured human L cells (2013)

Primary human colonic cultures provide an in vitro model for interrogating the human enteroendocrine system, and co-secrete GLP-1 and PYY. We found no evidence of PYY-specific cells not producing GLP-1. GLP-1 secretion was enhanced by small molecule agonists of GPR40/120 and GPBAR1.

Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry of Heteropolyflavan-3-ols and Glucosylated Heteropolyflavans in Sorghum [<i>Sorghum bicolor</i> (L.) Moench] (2002)

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used to characterize the structural diversity of polyflavans in Ruby Red sorghum [Sorghum bicolor (L.) Moench]. Deionization of the polyflavan fractions with Dowex 50 x 8-400 cation-exchange resin and subsequent addition of cesium trifluoroacetate ((133)Cs) allowed the detection of exclusively [M + Cs](+) ions. MALDI-TOF MS of the polyflavans that eluate from Sephadex LH-20 columns with methanol and acetone detected a series of masses corresponding to heteropolyflavan-3-ols differing in degree of hydroxylation and nature of the interflavan bond (A-type and B-type). MALDI-TOF MS of the Sephadex-ethanol/methanol (v/v) eluate revealed a series of masses corresponding to heteropolyflavan-5-O-beta-glucosides that vary in the extent of hydroxylation and contain a flavanone (eriodictyol or eriodictyol-5-O-beta-glucoside) as the terminal unit. The combination of liquid chromatographic separation and MALDI-TOF MS to characterize sorghum polyflavans indicates that the structural heterogeneity is much greater than previously described.
Resolving the Completion Engineer's Dilemma: Permanent or Retrievable Packer? (2002)

Abstract Traditionally, completion engineers have faced a dilemma when deciding whether to run a large bore, hydraulic set, permanent, or retrievable packer. Thanks to advances in cutting technology, this decision is no longer an either/or proposition. The innovative alternative is the removable packer. This paper will address the development of a removable packer that combines the best features of both permanent and retrievable packers: large bore, high performance, simple design, and flexible retrieving options. The paper will trace the development of the technique from stack-up testing to the maiden run and retrieval of the first removable packer in the Milne Point field, Alaska. Through analysis of this case history, the paper will address challenges faced, problems solved and lessons learned that are now being applied to future enhancements of the removable packer technique.
Isolation of Genes Required for Hydrogenase Synthesis in Escherichia coli (1987)

A mutant strain of Escherichia coli, strain AK23, is devoid of hydrogenase activity when grown anaerobically on glucose and cannot grow on H2 plus fumarate. From E. coli chromosomal DNA library, a plasmid, pAK23, was isolated which restored hydrogenase activity in this strain. Two smaller plasmids, pAK23C and pAK23S, containing different parts of the insert DNA fragment of plasmid pAK23, were isolated. The former plasmid restored activity in strain AK23 while the latter did not. The smallest active DNA fragment in plasmid pAK23C was 0.9 kb. This gene is designated hydE. Plasmids pAK23 and pAK23S restored activity in another hydrogenase-negative strain, SE-3-1 (hydB), while plasmid pAK23C did not, suggesting that plasmid pAK23 contains two genes required for hydrogenase expression. Strain AK23 was also devoid of formate hydrogenlyase and formate dehydrogenase activities and these activities were restored by some of the plasmids. Hydrogenase and formate-related activities in strain AK23 were restored by growth of cells in a high concentration of nickel. Plasmid pAK23C led to synthesis of a polypeptide of subunit molecular mass 36 kDa and plasmid pAK23S led to synthesis of polypeptides of subunit molecular masses 30 and 41 kDa.
