Interaction phenomena in polymer bonded permanent magnet powders (1993)

Magnetization measurements are made on polymer bonded melt-spun Nd-Fe-B and on Sm-Co 2:17 powder. Changes in remanence curves with volume fraction of magnetic filler are attributed to changes in the magnetic interaction between particles. Measurements on the remanent states indicate that this interaction increases rapidly with volume fraction at low volume fractions, and slowly at high volume fractions. It is shown that at coercivity, the variation in interaction with the volume fraction is slower than in the remanent state.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Class of Kernels for Sets of Vectors (2005)

Abstract. In some important applications such as speaker recognition or image texture classification, the data to be processed are sets of vectors. As opposed to standard settings where the data are individual vectors, it is difficult to design a reliable kernel between sets of vectors of possibly different cardinality. In this paper, we build kernels between sets of vectors from probability density functions level sets estimated for each set of vectors, where a pdf level set is (roughly) a part of the space where most of the data lie. 1
Oversampled Paraunitary DFT Filter Banks: A General Construction Algorithm and Some Specific Solutions (2011)

Oversampled filter banks are at the center of essential signal processing systems, either for source coding or for transmission applications. Among this class of filter banks (FBs), the case of oversampled discrete Fourier transform (DFT) filter banks is particularly important since it leads to efficient algorithm implementations. However, up to now, no general construction algorithm has been proposed to exhaustively cover the large set of the various solutions offered by this family of FBs. The paper recalls in detail the precise features of the rectangular paraunitary matrices that are specific of this type of systems. A parametrization method is proposed involving transformations, being either rotations or shifts, that depend upon the oversampling ratio and upon the prototype filter length. This shows that several factorizations exist leading to solutions of different dimension. Orthogonal and paraunitary patterns are introduced and, using a sequence of transformations applied to a pattern (STAP), an algorithm is derived that allows us to get the exhaustive set of solutions for various values of the oversampling ratio and prototype filter length. Furthermore, for some oversampling ratios, explicit expressions of some solutions are also provided that are valid whatever the maximum length of the prototype filter. Finally, design examples for linear and nonlinear phase prototype filters are presented.

Cardiac Fibroblasts Express the cAMP-Adenosine Pathway (2000)

The extracellular "cAMP-adenosine pathway" refers to the local production of adenosine mediated by cAMP egress into the extracellular space, conversion of cAMP to AMP by ectophosphodiesterase, and the metabolism of AMP to adenosine by ecto-5'-nucleotidase. The goal of this study was to assess whether the cAMP-adenosine pathway limits cardiac fibroblast growth. Studies were conducted in ventricular cardiac fibroblasts maintained in 3-dimensional cultures. Addition of exogenous cAMP to cardiac fibroblasts increased extracellular levels of AMP, adenosine, and inosine in a concentration-dependent and time-dependent manner. This effect was attenuated by blockade of total phosphodiesterase activity (3-isobutyl-1-methylxanthine), ectophosphodiesterase activity (high concentration of 1, 3-dipropyl-8-p-sulfophenylxanthine), or ecto-5'-nucleotidase (alpha, beta-methylene-adenosine-5'-diphosphate). Treatment with exogenous cAMP inhibited cell growth as assessed by DNA synthesis ((3)H-thymidine incorporation), cell proliferation (cell counts), and protein synthesis ((3)H-leucine incorporation). Antagonism of A(2) (KF17837) or A(1)/A(2) (low concentration of 1, 3-dipropyl-8-p-sulfophenylxanthine), but not A(1) (8-cyclopentyl-1, 3-dipropylxanthine), adenosine receptors blocked the growth-inhibitory effects of exogenous cAMP, but not the growth inhibitory effects of 8-bromo-cAMP (stable cAMP analogue). The growth-inhibitory effects of exogenous cAMP were enhanced by the combined inhibition of adenosine deaminase [erythro-9-(2-hydroxy-3-nonyl) adenine] and adenosine kinase (iodotubercidin). In conclusion, the extracellular cAMP-adenosine pathway exists in cardiac fibroblasts and attenuates cell growth. Pharmacological augmentation of this pathway could abate pathological cardiac remodeling in heart disease.
Enhancing Repeatability in the Measurement of Potential Drop using an Adjustable Four-Point-Probe Measuring System (2007)

The article describes an effective method of measurement for enhancing the repeatability in the experimental determination of electrical potential drop for the evaluation of materials. In the present approach, an averaging scheme is adopted for measuring the potential drop using a DC four-point-probe measuring system, where the associated probe contact distances on the material surface are adjusted in successive measurements by refreshing the individual contacts of the spring-loaded probes to the measuring surface. Statistical considerations are discussed in the context of repeatability of results using this method. Finally, the application of the method is demonstrated and discussed for a practical problem of interest, namely, the evaluation of rear-wall flaws (cracks and slots) in thick-walled structures. In an attempt to verify the accuracy, measured results are compared with the corresponding finite-element predictions of the potential drop. Results of the present study and also the comparative analysis firmly establish the appropriateness as well as reliability of the present potential-drop measuring system for obtaining repeatable measurements in the evaluation of materials.
Dynamic masking of application displays using OCR technologies (2009)

Industry coalitions are developing regulations to govern information sharing and to protect sensitive business data and the privacy of individuals. In many cases, these regulations make it impossible to outsource business operations, unless the companies have effective technologies to protect sensitive information. This paper addresses scenarios in which data servers and applications are owned and maintained on the premises of a company, and the service providers remotely access the data and the applications. We present a unique solution called Masking Gateway for Enterprises (MAGEN) that masks sensitive information appearing on application displays, without any interference with the applications that generate those screens. The major novelty lies in the utilization of optical character recognition (OCR) for analyzing and understanding application screens. Together with a comprehensive rule language, this approach makes it possible to characterize fields containing sensitive information and mask them according to predefined rules. The rule language is very flexible, abstract, and intuitive and is designed to cope with a vast set of policies and security needs. We describe the major challenges in implementing MAGEN and the results of experimenting with it in situations that occur in actual business settings. We outline techniques that optimize the OCR process to minimize latency and ensure robust operation.
Correlated Excimer Formation and Molecular Rotational Dynamics in Phenylacetylene Dendrimers (2000)

Steady-state and time-resolved fluorescence data are used to examine the photophysical characteristics of a series of phenylacetylene dendrimers. Correlated excimer formation is observed in some solvents which is found to depend strongly upon initial excited-state placement within the dendrimer framework. The results suggest two distinct solvated molecular environments which give rise to independent photophysical behaviors. Models of excimer formation dynamics and relaxation kinetics are described. Additionally, fluorescence anisotropy measurements are examined in the context of simultaneous probe wobbling-in-a-cone and macromolecular dendrimeric rotation as the mechanisms leading to fluorescence depolarization. Approximate solutions to the model are shown to provide good descriptions of the solvated molecular dynamics.
Central Heating Plant Economic Evaluation Program. Volume 5. Emission Regulations Data Management Program. (1995)

Abstract : Public Law has directed the Department of Defense (DOD) to rehabilitate and convert its existing domestic power plants to burn more coal. Other Federal legislation requires DOD to use the most economic fuel for any new heating system. This five-volume report discusses the Central Heating Plant Economic Evaluation Program (CHPECON), a computer program for screening potential new and retrofit steam/power generation facilities. Volume 1 is the Technical Reference. Volume 2 is the User's Manual. Volume 3 is the Military Base Weather Information Data Management Program. Volume 4 is the Coalfield Properties Information Data Management Program. Volume 5 is the Emission Regulations Data Management Program. CHPECON provides screening criteria to evaluate competing combustion technologies using coal, gas, or oil; detailed conceptual facility design information; budgetary facility costs; and economic measures of project acceptability including total life cycle costs and levelized cost of service. The program provides sufficient flexibility to vary critical design and operating parameters to determine project sensitivity and parametric evaluation. jg
Reverse-link control mechanisms in CDMA2000 revision-D: performance evaluation (2005)

CDMA2000 revision D introduces, among other things, reverse link enhancing features that can literally be considered a paradigm shift. In particular, hybrid ARQ (HARQ), 3 control mechanisms and 2 advanced mobile reporting techniques offer the tools necessary for the rapid and efficient coordination of high-rate mobile data transmissions. This paper focuses on the control mechanisms and examines how best to utilize them. System-level simulations then illustrate how they complement each other.
Predicting Driver Seeing Distance in Natural Rainfall (1981)

Four field studies were conducted in natural rainfall to develop a model for predicting distances at which drivers are able to see other vehicles in the roadway at various time periods following stoppage of a windshield-wiper stroke. The seeing distance prediction was developed as a function of rain intensity, rain accumulation time, and ambient daylight illumination. Two situations were studied; in the first, drivers seated in a stationary vehicle detected moving vehicles, and in the second, moving drivers detected a stationary vehicle. Useful seeing distance models were developed from the field studies. Seeing distances predicted from the models developed from these earlier studies were compared with seeing distances obtained in a subsequent validation field test. Results indicated that average error in the prediction of seeing distances ranges from 9% to 23%.
Optical parametric amplification of a 1.54- mu m single-mode DFB laser in a Ti:LiNbO/sub 3/ waveguide (1993)

Optical parametric amplification of radiation from a 1.54- mu m single-mode DFB laser in a Ti:LiNbO/sub 3/ waveguide has been investigated by measuring the idler created in the nonlinear process. The pump was a frequency-doubled Nd:YAG laser at 532-nm wavelength, operated either Q-switched or both Q-switched and mode-locked to avoid permanent surface damage and to minimize photorefractive index changes. On comparison with theoretical predictions, the output was found to correspond to a pump power one order of magnitude below the true power in the waveguide. The highest gain obtained was 4.7 dB with 49 W of pump power in a 27-mm-long waveguide. Although the experimental results can be improved, it is obvious that the major difficulty to overcome is the large pump power required. The prospect of decreasing the power requirement by using materials with higher effective nonlinear coefficients or by using quasi-phase-matching techniques is discussed. A more fundamental drawback is that the amplification is polarization dependent, and it is unclear how this can be handled.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Elbow Arthroscopic Surgery Update for Sports Medicine Conditions (2013)

Elbow arthroscopic surgery can now effectively treat a variety of conditions that affect athletes. Advances in instrumentation, increased surgeon familiarity, and expanded indications have led to significant growth in elbow arthroscopic surgery in the past few decades. While positioning, portal placement, and specific instruments may vary among surgeons, anatomic considerations guide surgical approaches to minimize neurovascular compromise. Arthroscopic procedures vary in difficulty, and surgeons should follow stepwise advancement with experience. Removal of loose bodies, debridement of synovial plicae, and debridement of the extensor carpi radialis brevis for lateral epicondylitis are considered simple procedures for novice elbow arthroscopic surgeons. More advanced procedures include management of osteochondritis dissecans, valgus extension overload in the throwing athlete, and capsular release. With proper technique, a variety of athletic elbow conditions can be treated arthroscopically with predictable results and minimal morbidity.

Physiological and morphological aspects of interactions between <i>Rhizobium meliloti</i> and alfalfa (<i>Medicago sativa</i>) in association with <i>Azospirillum brasilense</i> (1993)

In a 50-L pot experiment with Medicago sativa grown under nonsterile conditions, a combined treatment of Azospirillum and Rhizobium was measured against soil inoculated with Rhizobium or Azospirillum alone or a control with a low background level of autochthonous rhizobia. The combined treatment significantly increased the shoot length and weight at 6 weeks and the regrowth shoot weight at 14 weeks when compared with the treatment with Rhizobium alone. In 1.5-L pots in which gnotobiotic conditions were maintained, the combined treatment led to more nodules on the main root at intermediate Rhizobium concentrations, and a greater root surface area at intermediate and high Rhizobium concentrations after 2 weeks but not after 4 weeks. In pouch-grown seedlings, plants were inoculated with either Rhizobium alone or in combination with Azospirillum or applied together with a flavonoid, luteolin (a nodulation gene inducer), or with a cytokinin, benzyl adenine. Luteolin had similar effects to those of Azospirillum in increasing the main root nodule number and the total nodule number. With Fahraeus slides, a significant increase was observed in the number of root hairs and the root diameter in the presence of Azospirillum as compared with the control and Rhizobium alone. There was no increase in the total number of infection threads; however, the combined treatment caused a significant decrease in the percentage of infected root hairs.Key words: Rhizobium, Azospirillum, Medicago, flavonoid, inoculation.
Novel missense and frameshift mutations in the activin receptor-like kinase-1 gene in hereditary hemorrhagic telangiectasia (1998)

Hereditary Hemorrhagic Telangiectasia (HHT) is an autosomal dominant disorder characterized by multisystemic vascular dysplasia and recurrent hemorrhage. One of the causative genes is the activin receptor-like kinase-1 (ALK-1) gene located on chromosome 12q13. ALK-1 is an endothelial cell type I receptor for the TGF-β superfamily of ligands. As a number of mutations have been identified in the kinase domain of ALK-1, we initiated a mutation analysis specifically targeting the first four coding exons of ALK-1 in order to determine if mutations in the extracellular and transmembrane domains are also present in HHT. Six new mutations have been identified. Three frameshift mutations were identified in exons encoding the extracellular and transmembrane domains. These mutations would grossly truncate the ALK-1 protein and are thus classic null alleles. Three new missense mutations within the exons encoding the extracellular domain, in addition to two previously described missense mutations, are located at or near highly conserved cysteines. These mutations may disrupt intra- or inter-molecular disulfide bridges required for ligand binding. The combined data suggest that both severe and subtle changes in the ALK-1 amino acid sequence can lead to receptor dysfunction and result in the HHT disease phenotype.

Immediate‐ and Delayed‐Type Contact Hypersensitivity in Children Older than 5 Years With Atopic Dermatitis: A Pilot Study Comparing Different Tests (1994)

We conducted a prospective open study of immediate- and delayed-type contact hypersensitivity to food and other allergens in 33 children with atopic dermatitis (AD). The design of the study was exploratory and not randomized. Various methods for detecting immediate-type hypersensitivity were compared. Thirty-three children age 5 to 15 years with persistent AD were initially enrolled, but 3 dropped out. Nine patients had positive reactions to foods in the patch-scratch test, four had positive reactions in the skin application food test, and five had positive reactions to foods in the prick tests. Positive reactions to foods were observed in only three patients on the delayed-type patch tests. In all tests, but especially the patch-scratch and prick tests, positive reactions to food allergens were observed without clinically related symptoms. None of these tests gave ideal results. Twenty (67%) of the 30 children had positive reactions to inhalants in prick testing. Fourteen showed positive patch-test reactions with the European standard series (True Test). The most positive reactions were to nickel (9 patients), cobalt, and balsam of Peru. Restrictive measures led to evident improvement of AD only in some children. The results of this study illustrate that food allergy plays only a limited role in patients with AD age 5 to 15 years. We could not conclude which of the tests would predict which children might benefit from dietary manipulation.
The Continuous Glucose Monitoring System (CGMS) in type 1 diabetic children is the way to reduce hypoglycemic risk (2002)

The CGMS is a useful device not only for detecting unrecognized hypoglycemia, but also for modifying insulin therapy in order to reduce hypoglycemic events. The system appears to be useful in avoiding long exposure to hypoglycemia.
Synthesis of Macromolecular Conjugates of a Urokinase Inhibitor: Amiloride (1999)

Amiloride is a potent inhibitor of a urokinase type plasminogen activator which is involved in the invasive process of cancer cells leading to the initiation of metastasis. Synthesis, characterization and in vitro tests of four macromolecular conjugates of Amiloride are presented. One of them is a degradable derivative, HPMA-Gly-D,l-Phe-Leu-Gly-amiloride. In this case the in vitro release of Amiloride was monitored. Other conjugates are stable containing a new amiloride derivative, 6-aminohexyl amiloride [AHA], coupled to different polymeric carriers: a branched polypeptide, poly-[Lys(AcGlu 1.0 -D,l-Ala 4.5 )] [AcEAK], poly-[N-(2-hydroxy propyl) metacrylamide] [HPMA] and poly-[1-vinyl-2-pyrrolidone- co-maleic acid] [NVP MA]. Inhibition of uPA, plasminogen activation and proteinases secreted by cancer cells was measured as well as basement membrane degradation in vitro. Each amiloride AHA and the corresponding conjugates retained their activity in these experiments.

Nucleophile‐Directed Selective Transformation of <i>cis</i>‐1‐Tosyl‐2‐tosyloxymethyl‐3‐(trifluoromethyl)aziridine into Aziridines, Azetidines, and Benzo‐Fused Dithianes, Oxathianes, Dioxanes, and (Thio)morpholines (2013)

A five-step procedure for the synthesis of cis-1-tosyl-2-tosyloxymethyl-3-(trifluoromethyl)aziridine was developed, starting from 1-ethoxy-2,2,2-trifluoroethanol, involving imination, aziridination, ester reduction, hydrogenation, and N-,O-ditosylation steps. Further synthetic elaborations revealed a remarkable difference in the reactivity of cis-1-tosyl-2-tosyloxymethyl-3-(trifluoromethyl)aziridine with respect to aromatic sulfur and oxygen nucleophiles, thus enabling the selective deployment of this versatile substrate as a building block for the synthesis of functionalized aziridines, azetidines, and benzo-fused dithianes, oxathianes, dioxanes, and (thio)morpholines.
