Vitamin E supplementation, plasma lipids and incidence of restenosis after percutaneous transluminal coronary angioplasty (PTCA). (1992)

To test whether alpha-tocopherol prevents restenosis following percutaneous transluminal coronary angioplasty (PTCA), we enrolled patients in a double-blind, placebo-controlled trial. Patients were randomized after successful PTCA to receive vitamin E in the form of dl-alpha-tocopherol, 1200 IU/day, orally vs an inactive placebo for 4 months. Patients' blood was analyzed at baseline and at 4 months post-PTCA for differences in plasma lipids, lipoproteins, apolipoproteins, alpha-tocopherol, retinol, beta-carotene and lipoperoxide concentrations. One hundred patients completed the protocol. No significant difference was found in any parameter except alpha-tocopherol level between the vitamin E group and the placebo group, verifying compliance. Follow-up cardiac catheterization was obtained in 83% of the patients receiving placebo and in 86% of the patients receiving dl-alpha-tocopherol. Including thallium and exercise stress testing, objective information was obtained for practically all the patients receiving dl-alpha-tocopherol or placebo. Restenosis was defined as the presence of a lesion with greater than or equal to 50% stenosis in a previously dilated artery segment and results were analyzed with respect to pre- and post-PTCA artery diameter, vessel diameter at follow-up, and restenosis rate. Patients receiving dl-alpha-tocopherol had a 35.5% restenosis angiographically documented vs 47.5% restenosis in patients receiving the placebo. The overall incidence of restenosis defined by an abnormal angiogram or thallium test or exercise stress test was 34.6% in patients receiving dl-alpha-tocopherol and 50% in patients receiving the placebo. This difference (p = 0.06) did not reach significance because of an inadequate sample size.
Topic Modeling for RDF Graphs (2015)

Topic models are widely used to thematically describe a collection of text documents and have become an important technique for systems that measure document similarity for classification, clustering, segmentation, entity linking and more. While they have been applied to some non-text domains, their use for semi-structured graph data, such as RDF, has been less explored. We present a framework for applying topic modeling to RDF graph data and describe how it can be used in a number of linked data tasks. Since topic modeling builds abstract topics using the co-occurrence of document terms, sparse documents can be problematic, presenting challenges for RDF data. We outline techniques to overcome this problem and the results of experiments in using them. Finally, we show preliminary results of using Latent Dirichlet Allocation generative topic modeling for several linked data use cases.
Adjustment of dental occlusion in treatment of chronic cervicobrachial pain and headache (1999)

The hypothesis that the response to conventional physical therapy of patients suffering from chronic cervicobrachial pain and/or headache can be improved by adjusting dental occlusion, was tested. Forty patients seeking treatment were interviewed and examined prior to treatment, and 6 weeks, 12 months and 60 months after treatment. All patients underwent routine physical therapies. They were pairwise matched for age, gender and type of dental occlusion, and randomly allocated to a true occlusal adjustment group or to a mock adjustment group. The patients and the examiners were unaware of the type of dental treatment given. The outcome variables included subjective pain and discomfort, cervical spine mobility and pain on movement, and comparison of relative EMG activities. The short-term response to therapy was good in both groups. In the long-term, however, the response was significantly better in the patients who had undergone occlusal adjustment than in the mock-adjusted controls.
Query Optimization for Energy Efficiency in Mobile Environments. (1993)

A complex analysis of acute kidney injury (AKI) in pregnant women shows that it is caused by the interaction of gestation-associated pathologies and beneficial signaling pathways activated by pregnancy. Studies report an increase in the regeneration of some organs during pregnancy. However, the kidney response to the injury during pregnancy has not been addressed. We investigated the mechanisms of the pregnancy influence on AKI. During pregnancy, the kidneys were shown to be more tolerant to AKI. Pregnant animals showed remarkable preservation of kidney functions after ischemia/reperfusion (I/R) indicated by the decrease of serum creatinine levels. The pregnant rats also demonstrated a significant decrease in kidney injury markers and an increase in protective markers. Two months after the I/R, group of pregnant animals had a decreased level of fibrosis in the kidney tissue. These effects are likely linked to increased cell proliferation after injury: using real-time cell proliferation monitoring we demonstrated that after ischemic injury, cells isolated from pregnant animal kidneys had higher proliferation potential vs. control animals; it was also supported by an increase of proliferation marker PCNA levels in kidneys of pregnant animals. We suggest that these effects are associated with hormonal changes in the maternal organism, since hormonal pseudopregnancy simulated effects of pregnancy.
Efficacy of Glyphosate on Populus Tremuloides as Affected by Droplet Size and Spray Volume (1996)

A low-volume laboratory research spray system and the spinning disk atomisers Flak, Herbi, and Micromax were used to study the effect of droplet size and spray volume on glyphosate efficacy on trembling aspen (Populus tremuloides Michx). Five droplet sizes, each with a narrow droplet spectrum, ranging from 177 to 1589 urn VMD were used. Spray volumes from 15 to 120 £/ha were tested. The phototoxicity of glyphosate increased as carrier volume was reduced (thereby increasing herbicide concentration), but was not affected by changes in droplet size. There was no significant interaction between droplet size, spray volume, and active ingredient (a.i.) rate per hectare. It is possible that the concentration gradient between the droplet and leaf, rather than the droplet coverage, is important for glyphosate phytotoxicity.
Les manuscrits de la chaîne du type VI sur les psaumes (1974)

La chaîne du type VI sur le psautier, selon la classification de G. Karo et de H. Lietzmann, commente les psaumes I-L. C'est la première partie de la chaîne palestinienne, la meilleure et la plus ancienne (VIe s.). Elle s'est conservée dans cinq manuscrits médiévaux, Oxford, Bibl. Bodl., Barocci 235 (B) du IXe- Xe s., Vatican, Vat. gr. 1789 (V) de la fin du Xe s., Munich, Bibl. Nat., gr. 359 (M) du Xe-XIe s., Athos, Iviron 597 (I) du XIe s., Bucarest, Académie roumaine gr. 931 + Istanbul, Bibl. patr., Panagias 9 (R) du XIe s. L'auteur décrit ces manuscrits et montre que le cod. Β, malheureusement lacuneux, est le prototype de toute la tradition manuscrite médiévale. Le cod. M est une copie directe du cod. Β. C'est probablement aussi le cas du cod. F, bien que l'hypothèse d'un intermédiaire perdu ne puisse pas être absolument écartée. Les codd. I et R ne dérivent certainement ni de M, ni de V, ni du modèle hypothétique de V, ni l'un de l'autre. Il résulte de ces observations que, lorsque le cod. B est lacuneux, les éditeurs ne peuvent négliger aucun des quatre manuscrits qui en descendent.
Biodegradation of 3,4‐dichloroaniline in a fluidized bed bioreactor and a steady‐state biofilm Kinetic model (1991)

Mixed culture of microorganisms immobilized onto Celite diatomaceous earth particles were used to degrade 3,4-dichloroaniline (34DCA) in a three-phase draft tube fluidized bed bioreactor. Biodegradation was confirmed as the dominant removal mechanism by measurements of the concomitant chloride ion evolution. Degradation efficiencies of 95% were obtained at a reactor retention time of 1.25 h. A mathematical model was used to describe the simultaneous diffusion and reaction of 34DCA and oxygen in the biofilms on the particles in the reactor. The parameters describing freely suspended cell growth on 34DCA were obtained in batch experiments. The model was found to describe the system well for three out of four steady states and to predict qualitatively the experimentally observed transition in the biofilm kinetics from 34DCA to oxygen limitation.
Design of an efficient position sensitive gamma ray detector for nuclear medicine (1986)

The shortcomings of conventional scintillation cameras are analysed theoretically with a view towards improving performance at gamma ray energies above 140 keV. A camera design is proposed which incorporates several new features to obtain good spatial resolution from thicker crystals of sodium iodide. Computer simulations show that in addition to having good efficiency and spatial resolution, the new design allows parallax error correction and (possibly) Compton scattering correction at gamma energies up to 511 keV.
Overview and analysis of the polyprotein cleavage sites in the family <i>Potyviridae</i> (2005)

SUMMARY The genomes of plant viruses in the family Potyviridae encode large polyproteins that are cut by virus-encoded proteases into ten mature proteins. Three different types of protease have been identified, each of which cuts at sites with a distinctive sequence pattern. The experimental evidence for this specificity is reviewed and the cleavage site patterns are compiled for all sequenced species within the family. Seven of the nine cleavage sites in each species are cut by the viral NIa-Pro and patterns around these sites are related where possible to the active site-substrate interactions recently deduced following the resolution of the crystal structure of Tobacco etch virus (TEV) NIa-Pro (Phan et al., 2002. J. Biol. Chem. 277, 50564-50572). In particular, a revised series of cleavage sites for Sweet potato mild mottle virus (genus Ipomovirus) is proposed with a conserved His at the P1 position. This is supported by homology modelling studies using the TEV structure as a template. The data also provide a standard to correct the annotation of some other published sequences and to help predict these sites in further virus sequences as they become available. Comprehensive data for all sequences of each virus in the family, together with some summaries, have been made available at http://www.rothamsted.bbsrc.ac.uk/ppi/links/pplinks/potycleavage/index.html.
A Petrov-Galerkin Finite Element Formulation for Convection Dominated Flows (1981)

In this thesis, a new finite element formulation for convection dominated flows is developed. The basis of the formulation is the streamline upwind concept, which provides an accurate multidimensional generalization of optimal one-dimensional upwind schemes. When implemented as a consistent Petrov-Galerkin weighted residual method, it is shown that the new formulation is not subject to the artificial diffusion criticisms associated with many classical upwind methods. The effectiveness of the streamline upwind/Petrov-Galerkin formulation for the linear advection diffusion equation is demonstrated with numerical examples. The formulation is extended to the treatment of the incompressible Navier-Stokes equations. An efficient implicit pressure/explicit velocity transient algorithm is developed which allows for several treatments of the incompressibility constraint and for multiple iterations within a time step. The algorithm is demonstrated on the problem of vortex shedding from a circular cylinder at a Reynolds number of 100.
An inductorless RC-based quadrature phase generator and its application to vector-sum phase shifter (2014)

An inductorless quadrature phase generator is designed and implemented in 0.18 μm CMOS technology. The proposed circuit is composed of two resistors, two capacitors, and four differential amplifiers. The performance of proposed circuit is verified by a single sideband (SSB) mixer and a vector-sum phase shifter. Measurement results show that the image rejection ratio is 42.38 dBc at 2.16 GHz. The measured RMS phase error and RMS magnitude error are below 3.5 degrees and 0.55 dB in 2–2.6 GHz, respectively.
Diagnosis As Planning: Two Case Studies (2011)

Diagnosis of discrete event systems amounts to finding good explanations, in the form of system trajectories consistent with a given set of partially ordered observations. This problem is closely related to planning, and in fact can be recast as a classical planning problem. We formulate a PDDL encoding of this diagnosis problem, and use it to evaluate planners representing a variety of planning paradigms on two realistic case studies. Results demonstrate that certain planning techniques have the potential to be very useful in diagnosis, but on the whole, current planners are far from a practical means of solving diagnosis problems.
Protein Phosphatase 2A Is Essential for the Activation of Ca2+-activated K+ Currents by cGMP-dependent Protein Kinase in Tracheal Smooth Muscle and Chinese Hamster Ovary Cells (1996)

The regulation of Ca2+-activated K+ channels (KCa channels) by cGMP-dependent protein kinase (cGMP kinase) and its molecular mechanism were investigated in Chinese hamster ovary (CHO) and tracheal smooth muscle cells. In CHO wild-type cells (CHO-WT cells) and in CHO cells stably transfected with cGMP kinase Ialpha (CHO-cGK cells), KCa channels with intermediate conductance (approximately 50 picosiemens) were identified. Due to the basal activity of cGMP kinase, Ca2+-activated K+ currents had a higher sensitivity toward the cytosolic Ca2+ concentration in CHO-cGK cells than in CHO-WT cells. Dialysis of the active fragment of cGMP kinase (300 n) into CHO-WT cells or of cGMP into CHO-cGK cells increased the Ca2+-activated K+ current, while the catalytic subunit of cAMP-dependent protein kinase (cAMP kinase) was without effect. In cell-attached patches obtained from freshly isolated bovine tracheal smooth muscle cells, the open state probability (NPo) of maxi-KCa channels (conductance of approximately 260 picosiemens) was enhanced by 300 microM 8-(4-chlorophenylthio)-cGMP, a specific and potent activator of cGMP kinase. In contrast, 1 microM isoprenaline, 20 microM forskolin, and 3 mM 8-bromo-cAMP failed to enhance KCa channel activity. In excised inside-out patches, only the active fragment of cGMP kinase (but not that of cAMP kinase) increased NPo when applied to the cytosolic side of the patch. The enhancement of NPo by cGMP kinase was inhibited in CHO cells as well as in tracheal smooth muscle cells by the cGMP kinase inhibitor KT 5823 (1 microM) and the protein phosphatase (PP) inhibitors microcystin (5 microM) and okadaic acid (10 nM). The catalytic subunit of PP2A (but not that of PP1) mimicked the effect of cGMP kinase on NPo in excised inside-out patches. The results show that cGMP kinase regulates two different KCa channels in two unrelated cell types by the same indirect mechanism, which requires the activity of PP2A. The regulation of the KCa channel is specific for cGMP kinase and is not mimicked by cAMP kinase.
Autoimmune Inner Ear Disease (AIED) (1997)

A portion of idiopathic rapidly progressive sensorineural hearing loss (SNHL) cases can be attributed to an immunological process in the cochlea that has been designated "autoimmune inner ear disease" (AIED). AIED is characterized by asymmetric bilateral SNHL that progresses over weeks or months, is often accompanied by vestibular symptoms, and responds positively to immunosuppressant medication. Historically, the inner ear was thought to be protected from autoimmune pathology; however, recent evidence suggests that the perisacular tissue surrounding the endolymphatic sac contains the necessary components for an immunological reaction. In addition, the inner ear is capable of producing an autoimmune response to sensitized cells that can enter the cochlea from the circulatory system through the spiral modiolar vein. Thus, AIED can be organ-specific, originating within the inner ear, or non-organ-specific, originating outside the inner ear. Although AIED is a recognized form of SNHL that may be stabilized or even reversed by appropriate medication, it remains the subject of controversy and debate. This paper discusses the pathogenesis of AIED, diagnostic strategy and treatment procedures for AIED, and the role of the audiologist in patient management.
Hidden Markov model for intelligent extraction of robot trajectory command from demonstrated trajectories (2002)

This paper proposes a scheme for selecting the best robot trajectory from a number of demonstrated trajectories. The selection scheme is based on the hidden Markov model (HMM) technique and is divided into four stages. The first stage is the representation of human demonstration by a HMM. The second stage is the preprocessing of input trajectories, which includes transformation of the position trajectory to its frequency spectrum function by the short-time Fourier transformation and mapping of the frequency spectrum function to discretized codes by vector quantization. The third stage relates to the training of the HMM. Having a number of repeated demonstrations, we get multiple observation sequences to tune the HMM parameters so that the trained model is the best one to represent the demonstrations. The last stage is the measurement of the quality of each trajectory. With each trajectory sent through the trained HMM model, a generated likelihood index is obtained which reflects the consistency of the trajectory with the HMM. The trajectory with the maximum likelihood index is considered to be the best for the robot to follow.
Properties of styrene-maleic anhydride copolymers containing wood-based fillers (1998)

Recycled newsprint (ONP) and dry process aspen fiber were combined with styrene maleic anhydride (SMA) copolymers containing either 7 or 14 percent maleic anhydride. The fiber-filled SMA composites were equivalent or superior to unfilled SMA in strength, stiffness, and notched Izod impact strength. ONP performed surprisingly well as a filler. Unnotched Izod impact strengths for filled polymers were lower than for unfilled polymers. Water sorption was similar among fillers, and was small compared with solid wood.
Natural Abundance of 13C in Serum Retinol Differentiates Between Dietary Intakes of C3 versus C4 Plants (2016)

Vitamin A is a micronutrient essential in vision, reproduction, immune function, and cellular differentiation. ProvitaminA carotenoids are plant sources of vitamin A. The isotopic distribution of 13C and 12C in humans is determined by what foods are consumed. C3 plants, i.e., green vegetables, carrots, and pumpkins, have lower 13C:12C than C4 staple crops, i.e., maize, sorghum, and millet. Vitamin A foods from corn-fed animals will reflect the13C:12C feed that the animals eat. The serum retinol13C:12C was previously evaluated as a biomarker for vegetable intake. The retinol13C:12C decreased in humans who increased their vegetable intake (range -26.21 to -31.57‰, P = 0.050) and correlated with provitamin A carotenoid intake (P = 0.079). The average δ difference was -0.526 with increased vegetable intake, while control increased by +0.370.A 2X2X2 study in Mongolian gerbils fed white and orange maize or carrots for an extended period of time.Serum retinol δ13C‰ differentiated between those consuming white maize and white carrots (–27.1±1.2 δ13C‰) from those consuming orange maize and white carrots (-21.6±1.4 δ13C‰, P<0.0001) and white maize and orange carrots (-30.6±0.7 δ13C‰, P<0.0001). This method was applied to Zambian children who had been fed either orange or white maize for two months. Those children who consumed orange maize had a lower δ13C‰ (-26.64±1.98) than their white maize-consuming counterparts (-27.39±1.94) (P = 0.049). In the application of this methodology to efficacy or effectiveness trials, it will be important to choose the appropriate control group and number of subjects for comparison analyses.

Objectives: We investigated changes in serum retinol relative differences of isotope amount ratios of 13C/12C (∂13C) caused by natural 13C fractionation in C3 compared with C4 plants as a biomarker to detect provitamin A efficacy from biofortified (orange) maize and high-carotene carrots.
Optical screen for direct projection of integral imaging (2006)

We describe a way to display three-dimensional images by integral imaging using an ordinary projector. We first explain a method that uses a large-aperture converging lens, then we explain the proposed method that uses two sets of lens array. Based on the principle of this new approach, front projection as well as rear projection is possible. Only a proper viewing area can be formed on the optical screen by this method, which improves the brightness of images on the screen. The projector itself does not need an additional optical system. We report on the results of an experiment carried out to confirm the validity of the proposed method.

Aberration limits for annular Gaussian beams for optical storage (1994)

Annularly apodized beams have been suggested for use in optical storage because of their potential to go beyond the conventional spot size and depth-of-focus limits. One concern for such applications is the effects of small aberrations on beams in which the energy is concentrated in a small annular ring. We present calculations and experimental results that show that annular apodization of a Gaussian beam reduces the sensitivity to defocus as well as balanced spherical and coma aberrations. The sensitivity to astigmatism is increased by a small amount.

A Remote Monitoring System of Logistics Carrier Based on Wireless Sensor Network (2018)

To improve the efficiency of the remote monitoring system for logistics transportation, we proposed a remote monitoring system based on wireless sensor network and GPRS communication. The system can collect information from the wireless sensor network and transmit the information to the ZigBee interpreter. The monitoring system mainly includes the following parts: Car terminal, GPRS transmission network and monitoring center. Car terminal mainly consists by the Zigbee microcontroller and peripherals, wireless sensor nodes, RFID reader, GPRS wireless communication module composed of a micro-wireless monitoring network. The information collected by the sensor communicates through the GPRS and the monitoring center on the network coordinator, sends the collected information to the monitoring center, and the monitoring center realizes the information of the logistics vehicle in real time. The system has high applicability, meets the design requirements in the real-time acquisition and information transmission of the information of the logistics transport vehicles and goods, and realizes the function of remote monitoring.
