Discovering Specific Semantic Relationships between Nouns and Verbs in a Specialized French Corpus (2004)

Recent literature in computational terminology has shown an increasing interest in identifying various semantic relationships between terms. In this paper, we propose an original strategy to find specific noun-verb combinations in a specialized corpus. We focus on verbs that convey a meaning of realization. To acquire these noun-verb pairs, we use ASARES, a machine learning technique that automatically infers extraction patterns from examples and counter-examples of realization noun-verb pairs. The patterns are then applied to the corpus to retrieve new pairs. Results, measured with a large test set, show that our acquisition technique outperforms classical statistical methods used for collocation acquisition. Moreover, the inferred patterns yield interesting clues on which structures are more likely to convey the target semantic link.
Compiling real-time digital signal processing applications onto multiprocessor systems (1992)

The goal of this research is to develop a set of Computer-Aided Design (CAD) tools to support the real-time implementation of Digital Signal Processing (DSP) applications onto multiple programmable processors. The work has resulted in a complete DSP design environment, called McDAS, which can compile high level DSP applications directly down to parallel code for MIMD multiprocessors.
One of the major challenges of the research is the assignment and scheduling of tasks onto the processors in such a way as to maximize the throughput of the resultant implementation while considering interprocessor communication delays and resource constraints imposed by the target architecture. The scheduler in McDAS exploits pipelining, retiming, and parallel execution simultaneously, allowing the environment to efficiently support a wide range of applications with different types of concurrency. Users can invoke the scheduler with different architecture configurations to explore implementation trade-offs.
The code generator is similarly retargetable to different multiprocessor architectures as well as core processors. Data buffers and synchronizations are automatically inserted to ensure correct execution. The final implementation can be used for simulation speedup or real-time processing.
The results on a set of benchmarks demonstrate McDAS's ability to achieve near optimal speedups across a wide range of applications.
Endothelial Cell–Specific FGD5 Involvement in Vascular Pruning Defines Neovessel Fate in Mice (2012)

We have identified FGD5 as a novel genetic regulator of vascular pruning by activation of endothelial cell-targeted apoptosis.
Super-hydrophobic surface with switchable adhesion responsive to both temperature and pH (2012)

In this article, we report a new super-hydrophobic surface with switchable adhesion that is responsive to both temperature and pH. When the water pH is fixed (pH = 7), a water droplet (4 μL) can roll on the surface at high temperature (45 °C) and be pinned at low temperature (20 °C). Simultaneously, the surface shows strong dependence on the pH of the water droplet, an acid droplet (pH = 2, 4 μL) can roll on the surface while a basic droplet (pH = 11, 4 μL) is pinned when the temperature is constant (45 °C). Reversible transition between the low adhesive rolling state and the high adhesive pinning state can be achieved by simply changing the temperature and/or the pH alternately. The smart effect of the surface is attributed to the cooperation of chemical variation of the poly(N-isopropylacrylamide-co-acrylic acid) P(NIPAAm-co-AAc) and the hierarchical structures on the surface. Such a novel super-hydrophobic surface with dual-responsive adhesion could potentially be used in a wide range of applications with more complex environments, such as biochemical separation, lab-on-chip devices and in situ detection.
Nutrients and Osteoporosis (1990)

AbstractOsteoporosis is a major epidemic in the United States, responsible for at least 1–2 million fractures per year. Current management of bone loss consists primarily of estrogen therapy and calcium supplements. This approach is helpful in many cases, but its success is limited. This review presents a new concept: that bone health depends not just on estrogen and calcium, but on a wide range of other nutrients, including vitamins B6, C, D, K, folic acid, magnesium, manganese, boron, zinc, copper, strontium and silicon. The typical Western diet, with its high content of sugar and refined foods, appears to be deficient in many of these vitamins and minerals. Furthermore, the requirement for certain nutrients may be increased by genetic factors or by metabolic changes that occur at the time of menopause. Failure to meet one or more of these nutritional needs could result in accelerated osteoporosis. On the other hand, supplementation with a balanced combination of appropriate micronutrients may prove to be a useful adjunct to calcium and estrogen therapy.Key Words: Vitamin Kvitamin Dmagnesiummanganesefolic acidboronstrontiumsiliconpyrixidoxinezinccopperascorbic acid micronutrientsdietboneosteoporosisabsorption
Massless Cable for Real‐time Simulation (2007)

Abstract A technique for real‐time simulation of hoisting cable systems based on a multibody nonideal constraint is presented. The hoisting cable constraint is derived from the cable internal energies for stretching and twisting. Each hoisting cable introduces two constraint equations, one for stretching and one for torsion, which include all the rigid bodies attached by the same cable. The computation produces the global tension and torsion in the cable as well as the resulting forces and torques on each attached body. The complexity of the computation grows linearly with the number of bodies attached to a given cable and is weakly coupled to the rest of the simulation. The nonideal constraint formulation allows stable simulations of cables over wide ranges of linear and torsional stiffness, including the rigid limit. This contrasts with lumped element formulations including the cable internal degrees of freedom in which computational complexity grows at least linearly with the number of cable elements – usually proportional to cable length – and where numerical stability is sensitive to the mass ratio between the load and the lumped elements.
Effects of bilingualism on verbal learning and memory in Hispanic adults (1995)

The effect of bilingualism on qualitative aspects of verbal learning and memory was investigated. Equivalent list learning tests in English and Spanish were carefully constructed, and compared across two bilingual Hispanic groups of Mexican origin that differed in their level of English proficiency ("balanced" and "nonbalanced" bilinguals) and a group of monolingual English-speaking non-Hispanic subjects. Groups were matched for age, education, and gender composition. Nonbalanced bilinguals assessed in English utilized semantic clustering to the same extent as monolinguals, but learned fewer words overall, and demonstrated lower retention scores compared to monolinguals. Comparisons of groups assessed in their dominant languages, however, revealed no significant differences on any of the learning and memory indices examined. In addition to comparisons with standard clinical memory indices, assessment issues concerning bilingual individuals are addressed.
Soma-Restricted Products of the Myelin Proteolipid Gene Are Expressed Primarily in Neurons in the Developing Mouse Nervous System (2003)

The myelin proteolipid gene encodes two sets of proteins, the classic PLP and DM20 and the sr (soma-restricted)-PLP and sr-DM20. Unlike the classic proteolipids, the sr-products are expressed in both neurons and oligodendrocytes (OLs) and are not components of the myelin sheath. In OLs, the sr-isoforms are associated with endosomes and recycling vesicles indicating a possible nonmyelin function for these proteins. In this study, a purified antibody specific for the sr-products was used to examine the expression of these proteins during the development of the mouse brain. We found that while sr-PLP and sr-DM20 are expressed in OLs, the highest levels of immunoreactivity were found in neuronal populations. During early embryonic development (E13-E15), sr-proteolipids were detected in the dorsal root ganglion and motor neurons in the spinal cord. By E17, immunostaining for sr-PLP and sr-DM20 in the brain increased dramatically. The highest levels of immunoreactivity were found during the first and second weeks postnatal after which staining intensity declined to adult levels and the pattern of expression was more restricted. Robust staining persisted in many neuronal populations including nuclei in the hindbrain, Purkinje and granule neurons in the cerebellum, pyramidal cells in the cortex and mitral cells in the olfactory bulb. The spatial and temporal pattern of sr-PLP and sr-DM20 expression is very similar to that of the endosomal protein, syntaxin 13, consistent with the finding that the sr-PLPs may play a role in vesicular transport in neurons.

AlAs etch-stop layers for InGaAlAs/InP heterostructure devices and circuits (1992)

Wet chemical etching solutions were developed that allow the selective etching of InP lattice-matched InGaAs and InAlAs compounds using thin pseudomorphic AlAs layers as etch stop. Several dicarboxylic acids were found that allow the etching of indium compounds. The best results were obtained for etchants consisting of succinic acid, ammonia, and hydrogen peroxide. The etch rate in In/sub 0.53/Ga/sub 0.47/As is found to be over 1000 times the etch rate of AlAs, while the etch rate of In/sub 0.52/Ga/sub 0.48/As is over 500 times that of the AlAs. The dependences of the succinic acid based etch on pH and hydrogen concentration were also studied. Buffered HF can be used to remove the AlAs stop layer, while it does not etch InGaAlAs to any significant degree.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Benzo‐ and indoloquinolizine derivatives. III. Synthesis and structural assignments of 4b,5,6,7,8,8a,10,11‐octahydro‐15b<i>H</i>‐tribenzo‐[<i>a,c,h</i>]quinolizine (4b,5,6,7,8,8a,10,11–octahydro‐15b<i>H</i>‐isoquino[2,1‐<i>f</i>] phenanthridine) (1975)

Abstract Starting from either trans ‐2‐phenylcyclohexylamine or the cis isomer, two epimers of 4b,5,6,7,8,8a,10,11‐Octahydro‐15b H ‐tribenzo[ a,c,h ]quinolizine have been synthesized. The four possible diastereoisomers of this compound were obtained by reduction of the enamine 5,6,7,8,10,11‐hexahydro‐15b H ‐tribenzo[ a,c,h ]quinolizine. Configuration and conformation are discussed by use of ir, 67.88 MHz cmr and 270 MHz pmr spectroscopy.
Bacteriophage-Mediated Control of a Two-Species Biofilm Formed by Microorganisms Causing Catheter-Associated Urinary Tract Infections in an<i>In Vitro</i>Urinary Catheter Model (2014)

Microorganisms from a patient or their environment may colonize indwelling urinary catheters, forming biofilm communities on catheter surfaces and increasing patient morbidity and mortality. This study investigated the effect of pretreating hydrogel-coated silicone catheters with mixtures of Pseudomonas aeruginosa and Proteus mirabilis bacteriophages on the development of single- and two-species biofilms in a multiday continuous-flow in vitro model using artificial urine. Novel phages were purified from sewage, characterized, and screened for their abilities to reduce biofilm development by clinical isolates of their respective hosts. Our screening data showed that artificial urine medium (AUM) is a valid substitute for human urine for the purpose of evaluating uropathogen biofilm control by these bacteriophages. Defined phage cocktails targeting P. aeruginosa and P. mirabilis were designed based on the biofilm inhibition screens. Hydrogel-coated catheters were pretreated with one or both cocktails and challenged with approximately 1×10(3) CFU/ml of the corresponding pathogen(s). The biofilm growth on the catheter surfaces in AUM was monitored over 72 to 96 h. Phage pretreatment reduced P. aeruginosa biofilm counts by 4 log10 CFU/cm2 (P≤0.01) and P. mirabilis biofilm counts by >2 log10 CFU/cm2 (P≤0.01) over 48 h. The presence of P. mirabilis was always associated with an increase in lumen pH from 7.5 to 9.5 and with eventual blockage of the reactor lines. The results of this study suggest that pretreatment of a hydrogel urinary catheter with a phage cocktail can significantly reduce mixed-species biofilm formation by clinically relevant bacteria.

X.500 Directory and OSI management (2003)

With the growth of interconnected network size and complexity, diverse requirements have risen for constructing a powerful information service. The concepts of management information base and directory information base are reviewed, and their similarities and differences are analyzed. It is shown that applying X.500 Directory to OSI management presents some interesting benefits. Several X.500 object classes are then proposed to represent management information in the directory. A model of information exchange is addressed briefly. It is suggested that a worldwide information sharing service for management applications can be achieved with the approach described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Neural network development foundations for low airspeed prediction (2003)

The object of this work was to establish the framework necessary for the future development of a neural network based system capable of accurately determining airspeed (magnitude and direction) for speeds under 40 knots which comprise what is known as the low airspeed regime. Ordinary airspeed measuring devices are unable to function properly within this range while advanced mechanical systems are so expensive that only the most sophisticated aircraft can afford them. Neural network predictions comparable in accuracy to these systems were successfully achieved. A self-organizing map was utilized to insure the selection of a compact, yet representative training set, while several paradigms were then applied to perform the predictions. From these tests, a radial basis function emerged as the best predictor. In addition, a study of network response to signal frequency content was performed which uncovered ample potential for further accuracy improvements.
A joint performance-vulnerability metric framework for designing ad hoc routing protocols (2010)

When a network is deployed in a hostile environment, different paths between nodes may provide varying levels of resilience to adversarial attack. Therefore, in order to ensure that network services are both timely and secure, both the vulnerability and performance of the path must be taken into account during route selection. However, current routing protocols do not take resilience of intermediate links into account, instead focusing on optimizing use of network resources. In this work, we propose a new class of resilience-enhanced routing protocols that incorporate the security of individual communication links when selecting a routing path. To enable resilient path selection, we introduce a joint performance-vulnerability metric, which quantifies the cost of a link based on both performance and vulnerability characteristics, so that shortest paths chosen using this metric will be both efficient and resilient to attack. We give an example that measures resilience to key exposure in ad hoc networks and demonstrate the feasibility of our scheme through analysis and simulation.
Towards Variation-Aware Test Methods (2011)

Nanoelectronic circuits are increasingly affected by massive statistical process variations, leading to a paradigm shift in both design and test area. In circuit and system design, a broad class of methods for robustness like statistical design and self calibration has emerged and is increasingly used by the industry. The test community's answer to the massive-variation challenge is currently adaptive test. The test stimuli are modified on the fly (during test application) based on the circuit responses observed. The collected circuit outputs undergo statistical post-processing to facilitate pass/fail classification. We will present fundamentals of adaptive and robust test techniques and their theoretical background. While adaptive test is effective, the understanding how it covers defects under different process parameter combinations is not fully established yet with respect to algorithmic foundations. For this reason, novel analytic and algorithmic approaches in the field of variation-aware testing will also be presented in the tutorial. Coverage of defects in the process parameter space is modeled and maximized by an interplay between special fault simulation and multi-constrained ATPG algorithms. These systematic approaches can complement adaptive test application schemes to form a closed-loop system that combines analytical data with measurement results for maximal test quality.
Abacavir, an anti–HIV-1 drug, targets TDP1-deficient adult T cell leukemia (2015)

Adult T cell leukemia (ATL) is an aggressive T cell malignancy caused by human T cell leukemia virus type 1 (HTLV-1) and has a poor prognosis. We analyzed the cytotoxic effects of various nucleoside analog reverse transcriptase inhibitors (NRTIs) for HIV-1 on ATL cells and found that abacavir potently and selectively kills ATL cells. Although NRTIs have minimal genotoxicities on host cells, the therapeutic concentration of abacavir induced numerous DNA double-strand breaks (DSBs) in the chromosomal DNA of ATL cells. DSBs persisted over time in ATL cells but not in other cell lines, suggesting impaired DNA repair. We found that the reduced expression of tyrosyl-DNA phosphodiesterase 1 (TDP1), a repair enzyme, is attributable to the cytotoxic effect of abacavir on ATL cells. We also showed that TDP1 removes abacavir from DNA ends in vitro. These results suggest a model in which ATL cells with reduced TDP1 expression are unable to excise abacavir incorporated into genomic DNA, leading to irreparable DSBs. On the basis of the above mechanism, we propose abacavir as a promising chemotherapeutic agent for ATL.
Cinchona Alkaloid-Catalyzed Asymmetric Trifluoromethylation of Alkynyl Ketones with Trimethylsilyl Trifluoromethane (2010)

The first catalytic enantioselective trifluoromethylation of alkynyl ketones 1 with (trifluoromethyl)trimethylsilane is disclosed by an operationally simple procedure, based on the combination of ammonium bromide of bis-cinchona alkaloids with Me(4)NF to afford trifluoromethyl-substituted tertiary propargyl alcohols (up to 96% ee), which are the important chiral building blocks for pharmaceuticals. Biologically attractive aryl heteroaryl trifluoromethyl carbinols were also synthesized.
Covert channels in the IP time to live field (2006)

Covert channels are used for the secret transfer of information. Unlike encryption, which only protects the information from unauthorised observers, covert channels aim to hide the very existence of the communication. The sheer amount of data and vast number of different network protocols in the Internet makes it an ideal high-capacity vehicle for covert communication. Covert channels pose a serious security threat as criminals can use them to hide their communication activities. In this paper we present a novel covert channel inside the IP header’s Time To Live (TTL) field. The sender manipulates the TTLs of subsequent packets transmitting covert information to the receiver. Since network elements along the path also modify the TTL, the capacity and stealth of this channel depend on the 'natural' TTL variation. We analyse this variation in multiple traffic traces and propose an encoding scheme, which makes the TTL covert channel look similar to “natural” variation. We also discuss methods to eliminate and detect this covert channel.
Preclinical Evaluation of New and Highly Potent Analogues of Octreotide for Predictive Imaging and Targeted Radiotherapy (2005)

These data suggest that the novel radiopeptides are superior to [(111)In/(90)Y-DOTA]-TOC and show great promise for the clinical application in the imaging of somatostatin receptor-positive tumors and their targeted radiotherapy.
Enantiomeric Resolution by HPLC on Silica‐Gel‐Bound, Optically Active Polyamides (1986)

Pressure-stable adsorbents for the direct HPLC separation of numerous racemic drugs are obtained by polymerization of the monomers 1 in the presence of acryloyl- or diolsubstituted silica gel. Optically active poly-acrylamides and polymethacrylamides that are not bound to silica gel have already proven useful in low-pressure chromatography.
Experimental Demonstration of Remote and Compact Imaging Spectrometer Based on Mobile Devices (2018)

Imaging spectrometers show great potential for environmental and biomedical sensing applications. Selfie sticks, which are tools used to take photographs or videos, have gained global popularity in recent years. Few people have connected these two objects, and few people have researched the application of imaging spectrometers to perform scientific monitoring in point-of-use scenarios. In this paper, we develop a compact imaging spectrometer (35 g in weight, 18 mm in diameter, and 72 mm in length) that can be equipped on a motorized selfie stick to perform remote sensing. We applied this system to perform environmental and facial remote sensing via motorized scanning. The absorption of chlorophyll and hemoglobin can be found in the reflectance spectra, indicating that our system can be used in urban greening monitoring and point-of-care testing. In addition, this compact imaging spectrometer was also easily attached to an underwater dome port and a quad-rotor unmanned aerial vehicle to perform underwater and airborne spectral detection. Our system offers a route toward mobile imaging spectrometers used in daily life.
