An X‐FEM and level set computational approach for image‐based modelling: Application to homogenization (2010)

Abstract The advances in material characterization by means of imaging techniques require powerful computational methods for numerical analysis. The present contribution focuses on highlighting the advantages of coupling the extended finite elements method and the level sets method, applied to solve microstructures with complex geometries. The process of obtaining the level set data starting from a digital image of a material structure and its input into an extended finite element framework is presented. The coupled method is validated using reference examples and applied to obtain homogenized properties for heterogeneous structures. Although the computational applications presented here are mainly two‐dimensional, the method is equally applicable for three‐dimensional problems. Copyright © 2010 John Wiley & Sons, Ltd.
Bandwidth limitation due to polarization mode dispersion (1995)

Polarization mode dispersion (PMD) is one of the troublesome issues for future global ultrahigh-speed optical networks.1 Various techniques for PMD measurement have been reported.2 However, the quantitative evaluation of PMD in the form of the transfer-function matrix has not been accomplished to date.
EFFECT OF THE RHIZOSPHERE MICROFLORA ON PASTEURIA PENETRANS PARASITIZING MELOIDOGYNE GRAMINICOLA (1997)

The effect of the rhizosphere microflora associated with spores of Pasteuria penetrans on the attachment of the spores on juveniles of Meloidogyne graminicola has been studied. The microflora stimulated the attachment of the spores on the juveniles and consequently reduced the invasion of the roots of tomato plants y the nematodes. The role of a helper rhizosphere microflora for biocontrol of root-knot nematodes by P. penetrans is suggested.

Stereoselective Synthesis of 3-Alkylideneoxindoles via Palladium-Catalyzed Domino Reactions (2005)

We have developed efficient catalytic methods for the stereoselective and diversity synthesis of various (E)-, (Z)-, and disubstituted 3-alkylideneoxindoles and 3-alkylidenebenzofuran-2-ones via palladium-catalyzed Heck/Suzuki-Miyaura, Heck/Heck, and Heck/carbonylation/Suzuki-Miyaura domino reactions.
The long-term potential of biodegradable poly(lactideco-glycolide) microparticles as the next-generation vaccine adjuvant (2011)

Biodegradable polymeric microparticles of poly(lactide-co-glycolide) (PLG) have been extensively evaluated for drug delivery and vaccine applications over the last three decades. Despite a wealth of studies on the use of PLG microparticles in vaccines through controlled release of antigens, there is no commercial PLG-based vaccine as yet. The key challenge that prevented the development of PLG microparticles as commercial vaccines was the instability of encapsulated antigen. Over the years, advancements were made towards maintaining antigen integrity during PLG microparticle preparation and sterilization. In parallel and independently, development of PLG microparticles as therapeutic commercial products established PLG with an excellent safety record in humans, and as a suitable candidate for next-generation vaccines. Through the combination of Toll-like receptor agonist encapsulation and surface adsorption of antigen, PLG microparticles can be used as a vaccine adjuvant to address unmet medical needs, such as vaccines against HIV, malaria and TB. With strategic development of PLG-based vaccines, PLG microparticles can offer advantages over the conventional vaccine adjuvants allowing commercial development of this adjuvant.
The bits and flops of the n-hop multilateration primitive for node localization problems (2002)

The recent advances in MEMS, embedded systems and wireless communication technologies are making the realization and deployment of networked wireless microsensors a tangible task. Vital to the success of wireless microsensor networks is the ability of microsensors to ``collectively perform sensing and computation''. In this paper, we study one of the fundamental challenges in sensor networks, node localization. The collaborative multilateration presented here, enables ad-hoc deployed sensor nodes to accurately estimate their locations by using known beacon locations that are several hops away and distance measurements to neighboring nodes. To prevent error accumulation in the network, node locations are computed by setting up and solving a global non-linear optimization problem. The solution is presented in two computation models, centralized and a fully distributed approximation of the centralized model. Our simulation results show that using the fully distributed model, resource constrained sensor nodes can collectively solve a large non-linear optimization problem that none of the nodes can solve individually. This approach results in significant savings in computation and communication, that allows fine-grained localization to run on a low cost sensor node we have developed.
An approach to seizure detection using an artificial neural network (ANN) (1996)

We have developed an EEG seizure detector based on an artificial neural network. The input layer of the ANN has 31 nodes quantifying the amplitude, slope, curvature, rhythmicity, and frequency components of EEG in a 2 sec epoch. The hidden layer has 30 nodes and the output layer has 8 nodes representing various patterns of EEG activity (e.g. seizure, muscle, noise, normal). The value of the output node representing seizure activity is averaged over 3 consecutive epochs and a seizure is declared when that average exceeds 0.65. Among 78 randomly selected files from 50 patients not in the original training set, the detector declared at least one seizure in 76% of 34 files containing seizures. It declared no seizures in 93% of 44 files not containing seizures. Four false detections during 4.1 h of recording yielded a false detection rate of 1.0/h. The detector can continuously process 40 channels of EEG with a 33 MHz 486 CPU. Although this method is still in its early stages of development, our results represent proof of the principle that ANN could be utilized to provide a practical approach for automatic, on-line, seizure detection.
Supervised Synonym Acquisition Using Distributional Features and Syntactic Patterns (2009)

Distributional similarity has been widely used to capture the semantic relatedness of words in many NLP tasks. However, parameters such as similarity measures must be manually tuned to make distributional similarity work effectively. To address this problem, we propose a novel approach to synonym identification based on supervised learning and distributional features, which correspond to the commonality of individual context types shared by word pairs. This approach also enables the integration with pattern-based features. In our experiment, we have built and compared eight synonym classifiers, and showed a drastic performance increase of over 60% on F-1 measure, compared to the conventional similarity-based classification. Distributional features that we have proposed are better in classifying synonyms than the conventional common features, while the pattern-based features have appeared almost redundant.
Numerical simulation of aerosol deposition from turbulent flows using three-dimensional RANS and LES turbulence models (2015)

In this study, three-dimensional computational fluid dynamics (CFD) simulations of particle deposition from turbulent flows in a vertical straight pipe were carried out, using the STAR-CCM+ v5.04 CFD package. The highlight of the study is the development of a post-processing approach for quantitatively assessing the accuracy of the Lagrangian particle tracking scheme. Three Reynolds-averaged Navier–Stokes (RANS) models and a large eddy simulation (LES) model were employed in the simulations, in conjunction with two wall treatment schemes and several near-wall mesh conditions. The particle deposition velocity was obtained based on the CFD simulation results, and compared to the experimental results. In post-processing, a “particle responsiveness factor,” defined as the ratio of particle mean square velocity fluctuation to fluid mean square velocity fluctuation for the wall-adjacent cells, was quantified using an Eulerian particle transport formulation. The particle responsiveness factor of the CFD simulations was then compared with that obtained using an empirical equation. The most accurate aerosol deposition results were obtained with a fine near-wall mesh (y+≈1) and resolved near-wall flow (no wall function). The LES model and the Reynolds stress model (RSM) produced the most accurate deposition velocity results, but the computation time of the former was up to ten times longer than that of the latter. The lower accuracy of the isotropic RANS models was attributed to their overprediction of the near-wall turbulence intensity gradient, and less accurate particle tracking as suggested by the particle responsiveness factor. The particle responsiveness factor, introduced for the first time in this study, was shown to be a useful index for evaluating accuracy of the Lagrangian particle tracking scheme due to its independence of specific knowledge of CFD algorithm and coding.

Novel therapeutic options in Acute Myeloid Leukemia (2016)

Acute myeloid leukemia (AML) is a biologically complex and molecularly and clinically heterogeneous disease, and its incidence is increasing as the population ages. Cytogenetic anomalies and mutation testing remain important prognostic tools for tailoring treatment after induction therapy. Despite major advances in understanding the genetic landscape of AML and its impact on the pathophysiology and biology of the disease, as well as the rapid development of new drugs, standard treatment options have not experienced major changes during the past three decades. Especially for patients with intermediate or high-risk AML, which often show relapse. Allogeneic hematopoietic stem cell transplantation (HSCT) remains the best chance for cure. Here we review the state of the art therapy of AML, with special focus on new developments in immunotherapies and cellular therapies including HSCT and particularly discuss the impact of new conditioning and haplo-identical donor regimens for HSCT, post-transplant strategies for preventing and treating relapse, and emerging novel therapeutic options.
Nonencapsulated Variant of <i>Cryptococcus neoformans</i> I. Virulence Studies and Characterization of Soluble Polysaccharide (1971)

A weakly virulent nonencapsulated variant of Cryptococcus neoformans is described. The chemical structure and antigenicity of the soluble polysaccharides produced by the variant strain and a typical virulent strain were compared. The soluble polysaccharides produced by both strains were composed of the same constituent monosaccharides; however, the virulent strain produced a polysaccharide having a greater uronic acid content and a larger molecular size than that of the variant strain. Soluble polysaccharides from the two strains are not closely related immunologically. Soluble polysaccharide obtained from the virulent strain did not affect persistence of the variant strain in mice.
Lymphocytes from Enlarged Iliac Lymph Nodes as Fusion Partners for the Production of Monoclonal Antibodies after a Single Tail Base Immunization Attempt (2006)

A novel method of preparing hybridomas producing mouse monoclonal antibodies was -established, called "the mouse iliac lymph node method". Lymphocytes from enlarged iliac lymph nodes from mice injected intramuscularly at the tail base with an emulsion of antigen and Freund's adjuvant were used for cell fusion. For the most part, lymph node lymphocytes from two mice were used for a single cell fusion attempt. Ovalbumin was used as the antigen and the results of fusion were compared with the results of a previous report (Cell Struct. Funct. 20; 151-156, 1995). Approximately 100 positive wells producing antibody of interest were identified using this method. By comparison, approximately 10 positive wells were identified using the more conventional mouse spleen method after three immunization injections. The relative proportions of hybridomas producing IgM, IgG1, IgG2a, IgG2b, and IgG3, following fusion using iliac lymph node lymphocytes obtained 14 days after injection were 14.0%, 78.7%, 3.2%, 3.5% and 0.5%, respectively. This method demonstrated the following advantages: (1) a single injection of the antigen emulsion was sufficient, (2) the lymph nodes were ready for use 14 days after injection, and (3) a high yield of positive hybridomas was obtained.
A New Model and Measurement Technique for Dynamic Shrinkage during Photopolymerization of Multi‐Acrylates (2005)

Abstract Summary: A novel experimental set‐up has been devised to measure simultaneously, in real time, the conversion and shrinkage of multi‐acrylates during photopolymerization. The data show that the current practice of assigning the excess volume entirely as excess free volume is inappropriate as this leads to an increasing fractional free volume with conversion. We propose to partition the excess volume into free and occupied volume components. The new model produces satisfactory results.

Circuit hot carrier reliability simulation in advanced CMOS process technology development (2002)

To establish the relation between circuit AC hot carrier (HC) degradation and DC testable parameters in early development stage of a deep submicron technology becomes the critical part of the process integration. DC Hot Carrier parameters, e.g. Idsat and Idlin, were found to be correlated to AC Ring Oscillator frequency degradation. The impact of crosstalk induced voltage overshoot to invertor hot carrier degradation was quantified by simulation. A set of designable parameters were used to ensure deep submicron technology hot carrier reliability.
An investigation of placental transferrin processing: influence of N-ethylmaleimide. (1990)

The uptake and processing of 125I-59Fe labelled diferric transferrin was studied with the single bolus technique using the isolated guinea-pig placenta. Following preperfusion of the placenta with the SH-alkylating agent N-ethylmaleimide preferential iron uptake was inhibited and a total blockade of transplacental iron transfer was obtained. It can be shown by means of subcellular fractionation studies that neither transferrin binding nor endocytosis of the transferrin receptor complex were affected by N-ethylmaleimide. Additional experiments performed with microvillous membrane vesicles isolated from control placentas or from placentas preperfused with N-ethylmaleimide demonstrated that N-ethylmaleimide does not affect the affinity of the transferrin receptor for its ligand. The number of receptors per mg membrane protein remains unchanged as well. Ka = 1.4 x 10(8) M-1, n = 3.6 x 10(12). The results show that the blockade is located at the level of endosomal iron release. Since it is known that N-ethylmaleimide inhibits the endosomal proton pump, our results strongly suggest that the endocytotic pathway is a necessary route in transferrin mediated transplacental iron transfer.
Extended-Range Arithmetic and Normalized Legendre Polynomials (1981)

An algorithm is presented for the computation of normalrzed Legendre polynomials. In order to permit wide ranges of argument, degree, and order of these functions, an "extended-range" arithmetic is introduced whereby a separate storage location is allocated to the exponent of a floatmg-pomt number. Since this device may have other applications, separate subroutines are developed for addition of extended-range numbers and also for conversion to and from ordinary floating-point form.
Incomplete relation revision method based on template (2017)

Data quality is the core problem in the field of big data application. In practical applications, data are often derived from multi-source databases, which can cause named conflict and similar duplicate record problems. This paper proposed a method to solve the named conflict problem and similar duplicate record based on a given template. In order to find the relationship between the template data and the data to be unified, we segmented the data that to be unified, then built an extensional B tree based on these data. At the same time, we construct a NFA for each template value. By using these NFA, we can get the language pattern for each column in the template relation. Finally, we search each template value in the extensional B tree, if the template value can be found and the corresponding data to be unified can be accepted by the NFA based on the template value, we can use the template value to replace the data that need to be recovered. Then, the data can be consolidated and integrated to ensure the consistency and integrity of the data.
La métamorphose d'un genre : quelques descripteurs pour un genre scolaire de récit (2007)

L'article se situe dans le prolongement de celui de D. Malrieu qui a décrit certaines des variables morphosyntaxiques caractéristiques d'un conte didactique.<br />Ce même conte, lu en classe de 6ème, a servi de point de départ à l'écriture d'un épisode par les élèves. On analyse ces productions sous deux aspects :<br />- en reprenant les variables utilisées par la précédente analyse (aspect quantitatif) <br />- en étudiant la genèse de ce « genre scolaire de récit » par comparaison entre les trois versions (aspect qualitatif) sur deux des variables analysées : l'évolution du lexique, et celle des activités métalinguistiques.<br />On constate alors un infléchissement important du genre de départ, dû aussi bien à la réorientation magistrale qu'à la concentration significative des scripteurs sur les définitions métalinguistiques induites par la thématique du récit. Dans les deux cas, la créativité des scripteurs dépasse de loin à la fois le modèle prescrit et le conte original.
Optoelectronic RF signal mixing using an electroabsorption waveguide as an integrated photodetector/mixer (2000)

We demonstrate for the first time an electroabsorption (EA) waveguide utilized as an integrated photodetector/mixer for frequency conversion of radio frequency signals, through field-controlled absorption. Using an InAsP-GaInP multiple-quantum-well EA waveguide, a conversion loss of 18.9 dB was obtained at 10-mW optical local oscillator (LO) power, and a suboctave, two-tone spur-free dynamic range of 120.0 dB-Hz/sup 4/5/ was measured for an up-converted signal at 1.9 GHz. This scheme can be useful in antenna applications where optical LO signal distribution is used for frequency converting microwave signals.
Film Cooling With Large Density Differences Between the Mainstream and the Secondary Fluid Measured by the Heat-Mass Transfer Analogy (1977)

The effect of large density differences on film cooling effectiveness was investigated through the heat-mass transfer analogy. Experiments were performed in a wind tunnel where one of the plane walls was provided with a porous strip or a row of holes with three-diameter lateral spacing and inclined 35 deg into the main stream. Helium, CO2, or refrigerant F-12, was mixed with air either in small concentrations to approach a constant property situation or in larger concentration to produce a large density difference and injected through the porous strip or the row of holes into the mainstream. The resulting local gas concentrations were measured along the wall. The density ratio of secondary to mainstream fluid was varied between 0.75 and 4.17 for both injection systems. Local film effectiveness values were obtained at a number of positions downstream of injection and at different lateral positions. From these lateral average values could also be calculated. The following results were obtained. The heat mass-transfer analogy was verified for injection through the porous strip or through holes at conditions approaching a constant property situation. Neither the Schmidt number, nor the density ratio affects the film effectiveness for injection through a porous strip. The density ratio has a strong effect on the film effectiveness for injection through holes. The film effectiveness for injection through holes has a maximum value for a velocity ratio (injection to free stream) between 0.4 and 0.6. The center-line effectiveness increases somewhat with a decreasing ratio of boundary layer thickness to injection tube diameter.

The fractures are subparallel to each other in a single pebble and are within numerous pebbles in an outcrop. We show that intrapebble tension could develop due to the amplification of the stresses inside a competent pebble embedded within a compliant matrix; furthermore, tensile stresses may form in the pebbles, even under compressive tectonic stresses. The regional trends of the fractures are consistent in each of the study areas, and they appear to be excellent indicators of the tectonic stresses. The derived angles between σhmax (the largest horizontal compression) and the dominant local strike-slip fault is about 40° in the En Yahav region of the Dead Sea rift, and about 75° in the Indio Hills area of the Salton trough; these angles are in agreement with other stress data.
