Controllable synthesis of novel one-dimensional carbon nanomaterials on an alkali-element-modified Cu catalyst (2005)

A series of novel one-dimensional carbon nanomaterials have been synthesized on an alkali-element-modified Cu catalyst, via a simple chemical vapour deposition method. The alkali-element doping of the Cu catalyst plays a key role in the controllable synthesis of carbon nanomaterials, signifying a novel approach to modifying the Cu catalyst. Owing to their unique morphology and fine quality, the synthesized carbon nanomaterials have fascinating potential applications in nanometre-sized electronic devices.
EXPERIMENTAL INVESTIGATION OF INFLATABLE CYLINDRICAL CANTILEVERED BEAMS (2008)

This paper investigates experimentally the bending of inflatable cylindrical cantilevered beams made of modern fabric materials. A dimensionless form of load vs deflection has been developed to characterize and generalize the bending behavior of the inflatable cylindrical cantilevered beams of different sizes, materials, and inflation pressures in a unified way for easy application. The dimensionless form of experimental results demonstrates that the inflatable beams, highly or lightly inflated, can be modeled by the Euler beam theory accurately before wrinkle occurs. The initial wrinkle is hardly noticeable in the experiments and the transition from non-wrinkle to wrinkle is mainly defined by the slope change of load-deflection curve. Compared with the experimental data, the strain-based wrinkle moment provides a lower bound prediction while the stress-based wrinkle moment gives an upper bound prediction. In the post-wrinkle stage, the Euler beam theory using a nonlinear moment-curvature model gives an upper bound estimation of load-deflection relationship while the finite element analysis based on membrane theory gives a lower bound estimation. The actual collapse moment is hard to measure in experiments due to the
Antenna and propagation impairments of a UWB localization system integrated into an aircraft cabin (2010)

In this paper we discuss some antenna and propagation aspects involved with the development of a localization system based on Ultra WideBand (UWB) technology intended for the integration into an aircraft cabin. The reference station consists of a pair of UWB monopoles that are integrated into the ceiling of the cabin. The integration is realized in a way to generate a directive down-tilted antenna pattern in order to illuminate the aisle of the cabin. The UWB radio channel of the cabin is characterized using a commercial ray tracing software. The influence of the antennas and the channel on the received pulse shape at the reference station launched by a mobile transmitter in the aisle of the cabin is investigated.
Development of a Novel Biodegradable Superporous Hydrogel for Gastroretentive Application (2013)

The objective of the study was to design and evaluate a novel superporous hydrogels (SPHs) for application as gastroretentive dosage form of losartan potassium. The semi-interpenetrating polymer network (IPN) SPHs of polyvinyl pyrrolidone and chitosan was synthesized by crosslinking chitosan with glyoxal. SEM photographs show the presence of interconnected pores. The prepared SPHs were highly sensitive to pH of swelling media, and showed reversible swelling and deswelling behaviors maintaining their mechanical stability. Drug release fitted best to the Korsmeyer-Peppas model. The studies showed that semi-IPN SPHs could be used as a gastroretentive drug delivery system.
Schottky-barrier normally off GaN/InAlN/AlN/GaN HEMT with selectively etched access region (2013)

A Schottky-barrier normally off InAlN-based high-electron-mobility transistor (HEMT) with selectively etched access regions, high off-state breakdown, and low gate leakage is presented. Metal-organic chemical vapor deposition-grown 1-nm InAlN/1-nm AlN barrier stack is capped with a 2-nm-thick undoped GaN creating a negative polarization charge at a GaN/InAlN heterojunction. Consequently, the gate effective barrier height is increased, and the gate leakage as well as the equilibrium carrier concentration in the channel is decreased. After removal of the GaN cap at access regions by using a highly selective dry process, the extrinsic channel becomes populated by carriers. Normally off HEMTs with 8-μm source-to-drain distance and 1.8-μm -long symmetrically placed gate showed a source drain current of about 140 mA/mm. The HEMT gate leakage at a drain voltage of 200 V and grounded gate is below 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-7</sup> A/mm with a three-terminal device breakdown of 255 V. The passivated InAlN surface potential has been calculated to be 1.45 V; significant drain current increase is predicted for even lower potential.

(Cyanomethylene)tributylphosphorane (CMBP), which promoted the alkylation of various nucleophiles (HA) with alcohols (ROH) to give RA (Mitsunobu-type reaction), was prepared in two steps starting from chloroacetonitrile.
Binding of purine nucleotides to two regulatory sites results in synergistic feedback inhibition of glutamine 5-phosphoribosylpyrophosphate amidotransferase. (1994)

Glutamine 5-phosphoribosylpyrophosphate amidotransferase from Escherichia coli is subject to synergistic feedback regulation by adenine and guanine nucleotides. Inhibition assays and equilibrium binding measurements have established that synergistic inhibition by AMP and GMP results from synergistic binding to two sites/enzyme subunit in the homotetramer. Although each nucleotide can bind to both sites, analyses of the wild type and mutant enzymes indicate that binding of GMP to an A (allosteric) site and AMP to a proximal C (catalytic) site are necessary for synergistic inhibition. K326Q and P410W amino acid replacements result in decreased binding affinity for GMP and AMP and lead to corresponding reductions in feedback inhibition. The K326Q A site mutation results not only in decreased affinity of GMP for the mutant A site but also has an adverse effect on AMP affinity for the C site. Similarly, the P410W C site mutation has a detrimental effect on binding of AMP to the mutant C site and also on affinity of GMP to the A site. The fact that a mutation in one site affects binding of nucleotides to both sites provides further evidence for synergistic binding of nucleotides.

Seroepidemiology of HTLV-I/II in universal screening of blood donations in France (1993)

Sixty-two per cent of HTLV-I/II-infected blood donations would not have been discarded through the previous targeted HTLV screening or through other mandatory tests, including anti-hepatitis B core. To avoid false-positive results, we propose a new algorithm of diagnosis.
Failure-resilient transaction management in multidatabase (1991)

Failure recovery in a multidatabase environment is addressed. It is shown that local autonomy considerations force the designer of a multidatabase system to trade off certain desirable properties to achieve reliability for transaction management. Representative techniques in the research literature are contrasted and compared. The author's approach to the problem is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Modeling antennas printed on magnetized substrate: Application to the design of a tunable PIFA antenna (2015)

A miniature reconfigurable PIFA antenna (Printed-Inverted-F-Antenna) is investigated in this paper. This antenna is printed on magneto-dielectric substrate. The tunability is achieved by the application of an external DC magnetic biasing field, thanks to the field-dependent permeability of the substrate. In order to design this antenna a modeling tool is implemented. It consists in coupling a magnetic material model and EM simulator. The “General Permeability Tensor” (GPT) model is used in order to determine the permeability tensor whatever the magnetization state of the substrate is. The coupling of the GPT model with an electromagnetic simulator (CST Microwave Studio R ®) allows for the complete description of microwave characteristics of the antenna. The confrontation between the measurement and simulation for different applied DC biasing fields allows enhancing and validating the theoretical approach developed.
Toward a comprehensive understanding of angler involvement (1992)

This paper synthesizes recent Cornell University studies on recreation involvement with special emphasis on fishing. It examines angler involvement from a broader perspective that includes goals/motives for involvement, and changes in these goals that may occur over time or even from one experience to the next.
Principal component analysis of cross sections of tongue shapes in vowel production (1997)

Images of the vocal tract provide the speech researcher with new and unique data. However, quantification of the “biologically important” features present in the image is a significant challenge because these features are typically complex, inherently variable and difficult to describe. The present study quantified cross-sectional tongue shape for vowels in a single plane (post-alveolar) using Principal Component Analysis. A single subject repeated eleven English vowels in two consonant contexts, five times each. Each of the resulting cross-sectional waveshapes (tokens) was represented by 70 samples. The 110 tokens were placed in a 110 × 70 matrix for PCA. The resulting principal components represent a basis set of orthonormal waveshapes with properties particularly suitable for the present project. The first two components accounted for 93% of the variance in the data. The loadings of the eleven vowels on the first two PCs indicated three distinct shape groups. These were examined statistically and found to represent high vowels, front vowels and back vowels. L'imagerie du conduit vocal fournit aux chercheurs en parole des données nouvelles et uniques. Cependant, savoir quantifier l'importance biologique des caractéristiques présentes dans l'image est un enjeu important, car ces caractéristiques sont typiquement complexes, intrinsèquement variables et difficiles à décrire. Ce papier présente l'analyse en composantes principales de la forme de la langue dans le plan coronal (post-alvéolaire) pour les 11 voyelles de l'anglais, répétées 5 fois, par un seul locuteur et dans deux contextes consonantiques. Chacun des contours dans le plan coronal a été représenté par 70 points. Les 110 contours ont été placés dans une matrice 110 × 70 pour l'analyse en composantes principales. Les composantes principales ainsi extraites constituent une base orthonormale dont les propriétés sont particulièrement intéressantes. Les deux premières composantes rendent compte de 93% de la variance mesurée sur les données. Les coefficients de pondération des 11 voyelles selon ces deux premières composantes font apparaître 3 groupes distincts. Ces groupes ont été analysés statistiquement, et se sont révélés représentatifs des voyelles hautes, des voyelles avant et des voyelles arrières.
Sex differences in human adipose tissues – the biology of pear shape (2012)

Women have more body fat than men, but in contrast to the deleterious metabolic consequences of the central obesity typical of men, the pear-shaped body fat distribution of many women is associated with lower cardiometabolic risk. To understand the mechanisms regulating adiposity and adipose tissue distribution in men and women, significant research attention has focused on comparing adipocyte morphological and metabolic properties, as well as the capacity of preadipocytes derived from different depots for proliferation and differentiation. Available evidence points to possible intrinsic, cell autonomous differences in preadipocytes and adipocytes, as well as modulatory roles for sex steroids, the microenvironment within each adipose tissue, and developmental factors. Gluteal-femoral adipose tissues of women may simply provide a safe lipid reservoir for excess energy, or they may directly regulate systemic metabolism via release of metabolic products or adipokines. We provide a brief overview of the relationship of fat distribution to metabolic health in men and women, and then focus on mechanisms underlying sex differences in adipose tissue biology.

The Double‐Pulley Technique for Double‐Row Rotator Cuff Repair (2007)

In an effort to maximize the area of footprint coverage, we developed the "double-pulley technique" for double-row rotator cuff repairs. Two suture anchors are inserted at the articular margin of the greater tuberosity (one anterior and one posterior). All 4 suture strands from each anchor are passed through a single medial point on the torn cuff. In this way, the 4 suture strands from the anteromedial anchor pass through 1 point in the cuff and the 4 strands from the posteromedial anchor pass through a different point in the cuff. A suture strand from 1 anchor is tied extracorporeally to a suture strand of the same color from the other anchor. The other ends of those 2 strands are then pulled, thereby delivering this extracorporeal knot into the joint and over the medial footprint. These 2 free suture strands are then tied together as a static knot. The procedure is repeated with the other sutures. This technique creates a double mattress suture medially, which compresses the intervening tendon bridge against its bone bed. We call this procedure the double-pulley technique because it uses the anchor eyelets as pulleys to deliver the extracorporeal knot into the shoulder. After the lateral row repair is performed, the rotator cuff footprint will be completely reconstituted.
Converting business documents:a classification of problems and solutions using XML/XSLT (2005)

The exchange of business documents can be realized either by standardizing or converting these documents. In this paper, we examine different conversion strategies from an economic perspective. In particular, we provide a classification of conversion problems as well as solutions using XML/XSLT.
Automatic Induction of Language Model Data for A Spoken Dialogue System (2005)

When building a new spoken dialogue application, large amounts of domain specific data are required.This paper addresses the issue of generating in-domain training data when little or no real user data are available.The twostage approach taken begins with a data induction phase whereby linguistic constructs from out-of-domain sentences are harvested and integrated with artificially constructed in-domain phrases.After some syntactic and semantic filtering, a large corpus of synthetically assembled user utterances is induced.The second stage involves sampling the synthetic corpus towards the goal of obtaining data that would be representative of the statistics of applicationspecific real user interactions.The sampling methods proposed employ an example-based generation framework, a simulated user model and information extracted from development data.Evaluation is conducted on recognition performance in a restaurant information domain.We show that word error rate can be reduced when limited amounts of real user training data are augmented with synthetic data derived by our methods.
Transcriptional and Posttranscriptional Control of mRNA from<i>lrt</i>A, a Light-Repressed Transcript in<i>Synechococcus</i> sp. PCC 70021 (1998)

Transcription regulation and transcript stability of a light-repressed transcript, lrtA, from the cyanobacterium Synechococcus sp. PCC 7002 were studied using ribonuclease protection assays. The transcript for lrtA was not detected in continuously illuminated cells, yet transcript levels increased when cells were placed in the dark. A lag of 20 to 30 min was seen in the accumulation of this transcript after the cells were placed in the dark. Transcript synthesis continued in the dark for 3 h and the transcript levels remained elevated for at least 7 h. The addition of 10 microM rifampicin to illuminated cells before dark adaptation inhibited the transcription of lrtA in the dark. Upon the addition of rifampicin to 3-h dark-adapted cells, lrtA transcript levels remained constant for 30 min and persisted for 3 h. A 3-h half-life was estimated in the dark, whereas a 4-min half-life was observed in the light. Extensive secondary structure was predicted for this transcript within the 5' untranslated region, which is also present in the 5' untranslated region of lrtA from a different cyanobacterium, Synechocystis sp. PCC 6803. Evidence suggests that lrtA transcript stability is not the result of differences in ribonuclease activity from dark to light. Small amounts of lrtA transcript were detected in illuminated cells upon the addition of 25 microg mL-1 chloramphenicol. The addition of chloramphenicol to dark-adapted cells before illumination allowed detection of the lrtA transcript for longer times in the light relative to controls without chloramphenicol. These results suggest that lrtA mRNA processing in the light is different from that in the dark and that protein synthesis is required for light repression of the lrtA transcript.
Residual stress analysis in chemical-vapor-deposition diamond films (2009)

Three groups of diamond films were deposited with variations in methane concentration, substrate material, and film thickness by a direct current chemical-vapor-deposition method. Stresses were measured by x-ray diffraction. The material reveals compressive stresses at the substrate interfaces due to thermal expansion mismatch. Increasing influence of defects leads to a drop in the compressive stresses and the formation of tensile stresses toward the growth front.
p53 and bcl-2 expression correlates with clinical outcome in a series of node-positive breast cancer patients. (1996)

p53 expression appears to be indicative of clinical outcome in postmenopausal patients treated with tamoxifen. Whether p53 overexpression and weak bcl-2 expression are indicators of biologic aggressiveness, regardless of treatment, or of hormone resistance remains to be defined.
Learning from Partial Labels (2011)

We address the problem of partially-labeled multiclass classification, where instead of a single label per instance, the algorithm is given a candidate set of labels, only one of which is correct. Our setting is motivated by a common scenario in many image and video collections, where only partial access to labels is available. The goal is to learn a classifier that can disambiguate the partially-labeled training instances, and generalize to unseen data. We define an intuitive property of the data distribution that sharply characterizes the ability to learn in this setting and show that effective learning is possible even when all the data is only partially labeled. Exploiting this property of the data, we propose a convex learning formulation based on minimization of a loss function appropriate for the partial label setting. We analyze the conditions under which our loss function is asymptotically consistent, as well as its generalization and transductive performance. We apply our framework to identifying faces culled from web news sources and to naming characters in TV series and movies; in particular, we annotated and experimented on a very large video data set and achieve 6% error for character naming on 16 episodes of the TV series Lost.
The filamentous type III secretion translocon of enteropathogenic Escherichia coli (2001)

Enteropathogenic Escherichia coli (EPEC) uses a type III secretion system (TTSS) to inject effector proteins into the plasma membrane and cytosol of infected cells. To translocate proteins, EPEC, like Salmonella and Shigella, is believed to assemble a macromolecular complex (type III secreton) that spans both bacterial membranes and has a short needle-like projection. However, there is a special interest in studying the EPEC TTSS owing to the fact that one of the secreted proteins, EspA, is assembled into a unique filamentous structure also required for protein translocation. In this report we present electron micrographs of EspA filaments which reveal a regular segmented substructure. Recently we have shown that deletion of the putative structural needle protein, EscF, abolished protein secretion and formation of EspA filaments. Moreover, we demonstrated that EspA can bind directly to EscF, suggesting that EspA filaments are physically linked to the EPEC needle complex. In this paper we provide direct evidence for the association between an EPEC bacterial membrane needle complex and EspA filaments, defining a new class of filamentous TTSS.
Interface Layers for High-k/Ge Gate Stacks: Are They Necessary? (2006)

We discuss the effects of interface layers between high-k gate insulators and the Ge substrate on the electrical characteristics of Ge MOS devices. Our work has focused on both germanium oxynitride (GeO x N y ) and tantalum oxynitride (TaO x N y ) interface layers. We find that ultrathin interface layers of TaO x N y , a high permittivity diffusion barrier, produce greatly improved charge trapping characteristics and promising capacitance scaling for high-k/Ge gate stacks. Effects of interface layers on interface state density and the frequency dispersion of the capacitance-voltage (CV) behavior under inversion are also described.
