Solvent and salt effects on the morphological structure of polyaniline (1995)

Extensive gel permeation chromatography coupled with surface structure and mechanical property measurements clearly indicate that polyaniline in the base form has a tendency to aggregate or agglomerate as a result of intermolecular hydrogen-bonding. The aggregation is present in the solid state powder. The degree of aggregation is found to be dependent on the prior history of the base powder material. In solution, the degree of aggregation is found to be dependent on the solvent, concentration, and temperature. As the solvent becomes a better solvent for the base material, the less aggregated is the structure. LiCl complexes the polymer via a 'pseudo-doping' process, thereby disrupting the internal polyaniline hydrogen-bonding and as a result, deaggregates the structure. As the polymer is deaggregated to different levels by a solvent or by LiCl, the individual chains can better be solvated and thus a conformational change occurs. The chains adapt a more expanded coil type of conformation. The degree of expansion depends on the solvation power of the solvent. These morphological changes have a dramatic effect on the surface structure properties of polyaniline as well as on bulk properties such as mechanical properties and UV/visible/near IR absorbance. As the level of deaggregation and subsequent chain extension increases, the surface structure becomes smoother, the glass transition temperature decreases and a significant red shift is observed in the (lambda) maximum of the absorbance. It is also found that the LiCl induced morphological changes result in increased conductivity upon doping polyaniline base with protonic acid.
Identification and Characterization of the Direct Interaction between Methotrexate (MTX) and High-Mobility Group Box 1 (HMGB1) Protein (2013)

These data demonstrate that HMGB1 is a direct binding protein of MTX. Moreover, binding of MTX to RAGE-binding region in HMGB1 inhibited the HMGB1/RAGE interaction at the molecular and cellular levels. These data might explain the molecular basis underlying the mechanism of action for the anti-inflammatory effect of MTX.

Determining functional units of tongue motion from magnetic resonance imaging (2014)

The human tongue produces oromotor behaviors such as speaking, swallowing, and breathing, which are executed by deforming local functional units using complex muscular array. Therefore, identifying functional units and understanding the mechanisms of coupling among them in relation to the underlying anatomical structures can aid significantly in the understanding of normal motor control and the development of clinical diagnoses and surgical procedures. Magnetic resonance imaging (MRI) has been widely used to observe detailed structures in the vocal tract and to measure internal tissue motion of the tongue. This work aims at determining the functional units from tagged MRI and muscle maps are extracted from high-resolution MRI. A non-negative matrix factorization method with a sparsity constraint is utilized to extract an activation map for each tissue point using a set of motion quantities extracted from tagged MRI including information from point trajectories (i.e., displacement, angle, and curvature) and strain. The activation map is then used to determine the coherent region using spectral clustering, revealing functional units and their relations to the underlying muscles. We test our algorithm on simple protrusion and speech tasks, demonstrating that the proposed algorithm can determine the correlated patterns of the tissue point tracking trajectories and strain.
An arm for a leg: Adapting a robotic arm for gait rehabilitation (2015)

The purpose of this study was to adapt a multipurpose robotic arm for gait rehabilitation. An advantage of this approach is versatility: a robotic arm can be attached to almost any point on the body to assist with lower- and upper-extremity rehabilitation. This may be more cost-effective than purchasing and training rehabilitation staff to use several specialized rehabilitation robots. Robotic arms also have a more human-like morphology, which may make them less intimidating or alien to patients. In this study a mechanical interface was developed that allows a fast, secure, and safe attachment between a robotic arm and a human limb. The effectiveness of this interface was assessed by having two healthy subjects walk on a treadmill with and without a robotic arm attached to their legs. The robot's ability to follow the subjects' swinging legs was evaluated at slow and fast walking speeds. Two different control schemes were evaluated: one using the standard manufacturer-provided control algorithm, and another using a custom algorithm that actively compensated for robot-human interaction forces. The results showed that both robot control schemes performed well for slow walking. There were negligible differences between subjects' gait kinematics with and without the robot. During fast walking with the robot, similar results were obtained for one subject; however, the second subject demonstrated noticeable gait modifications. Together, these results show the feasibility of adapting a multipurpose robotic arm for gait rehabilitation.

Aerodrome mapping databases supporting taxi routing functions (2011)

An electronic airport moving map is standard on today's aircraft, starting with the Airport Moving Map (AMM) on the Electronic Flight Bag (EFB) of the Boeing 777. Airbus followed with the Onboard Airport Navigation System (OANS) on the navigation display of the A380, and Boeing with integrated Airport Map with the navigation display on the 787 and 747–8. One of the next steps for AMM displays will be the display of assigned taxi routes. Input, management, and display of taxi routes in the cockpit have been covered in various studies in the past. However, regular use is not possible yet as Aerodrome Mapping Databases (AMDB) as specified in the industry standards RTCA DO-272 (User Requirements)[1], DO-291 (Exchange Format)[2], and ARINC 816 (Embedded Format)[3] do not contain the required connectivity information. The joint RTCA special committee SC-217 / EUROCAE WG-44 worked on this issue over the past two years and updated data requirements, data model, and capture rules accordingly. The approach was driven by various depiction concepts (highly-detailed vs. generalized) and taxi route input methods (i.e., SC-214 D-TAXI data links), but also data availability and the characteristics of taxi instructions from official sources (i.e., airport facility directives and the Notices to Airmen Publication). The result is a graph network with nodes and edges modeling taxiway and runway connectivities within an airport, called the Aerodrome Surface Routing Network (ASRN). Intersections are modeled by nodes of the graph. Other node types are used for holding positions or parking positions. Feasible connections between two nodes are modeled by edges of the graph. This paper provides an overview of the new elements of RTCA DO-272C and DO-291B and in particular about the specifications for the ASRN. The new standard documents (DO-272C/DO-291B) are scheduled for publication by end of 2011.
Anomalous phase in one-dimensional multilayer periodical structures with birefringent materials (2004)

We have studied biaxial, birefringent, one-dimensional multilayer structures and found a wavelength region where the phase of one specific polarizatin component of the transmitted field increases with wavelength, giving rise to unusual polarization dependent dispersive effects of the input beam. We have analysed the delay obtained with birefringent one-dimensional multilayer structures and the effect of the dispersion in the materials to generate anomalous phase in the spectrum.
Calcium Metabolism and Arteriosclerosis (1986)

It is reported that calcium antagonists have an antiatherosclerotic effect by some investigators. But the mechanism of the effect is obscure until now. As one of the mechanism of the antiatherosclerotic effect of calcium antagonist is reported that there is a stimuratory effect on PGI2 production of arterial smooth muscle cells (SMCs) and endothelial cells. We also reported that some kinds of calcium antagonist had a stimulatory effect on PGI2 release from cultured rat aortic smooth muscle cells. To study the mechanism of the effect of calcium antagonist, we investigated the motion of calcium in or extra SMCs.The method for culture of SMCs and the assay of PGI2 was the same as our previous report.To measure the calcium concentration we used Atomic Absorption method.As conclusion;1) Calcium in the medium tended to stimulate the growth of arterial SMCs in culture.2) Positive corelation with calcium concentration in the medium and the calcium content of intra SMCs in culture was observed.3) Calcium ionophore, A23187, increased calcium content of intra SMCs in culture.4) Calcium in the medium significantly increased the release of PGI2 into the medium in a dose-related manner.5) A23187 significantly increased the release of PGI2 into the medium dose-dependently.
Quantitative Trait Allele (QTA) for yield components in a modern sugarcane cultivar. (2001)

An extensive Quantitative Trait Allele (QTA) mapping study, based on 300 selfed progeny of the cultivar R570, was undertaken using more than 1000 AFLP markers. The genetic map gave access to about half of the genome studied. The population was evaluated in two replicated trials for yield components related to several morphological and technological traits recorded in two successive crop-cycles. Numerous QTAs were found at P = 5 x of which only one fourth might possibly be artefactual due to mere chance, depending on P. Their individual size effect ranged between 3% and 7% of the whole variation. QTA stability across years was improved when limiting threshold stringency. Epistatic interactions were also explored by looking for di-genic interactions at P = (5 x 10-3)2. Altogether the putative genetic factors revealed here explained from 30% to 55% of the total phenotypic variation depending on the trait. This is the first extensive QTA mapping study performed in cultivated sugarcane.
Apple, Test of Acaricides, 1973 (1976)

Abstract Experimental sprays were applied to run-off to single-tree plots in a randomized block design with 2 replicates of Golden Delicious and 2 York Imperial. Treated single-trees were separated by others not sprayed with acaricides. Experi-mental sprays were applied with a John Bean sprayer, 35 gpm pump, equipped with a spray mast carrying 7 spray guns arranged to wet the uniformly trimmed trees. Spray dates for the test acaricides were: Replicates A and C only July 5 and 6 (Treatments Omite 6 E 118 ml and Vydate 4 EC 118 ml were not applied); on July 12 and 13 all treatments except Vydate were applied to all plots in all 4 replicates; a simi-lar spray was applied on August 15; Vydate spray dates were May 17, June 1, June 15, July 2, July 16, August 2, and August 20. Effec-tiveness of the test acaricides on the European red mite was assessed by counting the mites several times during the season on samples of 20 leaves/tree, 80/treatment. Until the last count of the season on August 23, mite counts for the York Imperial trees. Replicates A and C, and for the Golden Delicious trees. Replicates B and D, were kept separate. The count of twospotted spider mites, predatory mites: Amblyseiusfallacis, and Zetzelliamali on August 23 are shown as mites/100 leaves to make the differences between treatments more apparent. Apple aphid data were collected by counting the number of infested terminals out of 10/tree, 40/treatment. Also the number of infested leaves per infested terminal was counted and the average calculated. Aaverage temperatures were: June 71.30° F, July 73.32° F, and August 73.53° F. Rainfall in inches was: June 5.04, July 2.03, and August 4.57.

Automatic tracking of MTPA trajectory in IPM motor drives based on AC current injection (2009)

The paper deals with a novel approach for the real-time tracking of the maximum-torque-per-ampere (MTPA) trajectory of an IPM motor drive. The proposed approach is based on the injection of proper tests signals and allows the MTPA trajectory to be learned and updated in the drive during steady-state conditions. The analytical development of the estimation algorithm, supported by a complete validation by simulation, is given in the paper. Finally experimental results are presented based on a prototype IPM drive system.
La glycoprotéine V soluble : un nouveau marqueur plasmatique de la thrombose artérielle (2004)

La glycoprotéine (GP) V fait partie du complexe GPIb-V-IX présent à la surface des plaquettes sanguines et responsable de leur adhésion au sous-endothélium en liant le facteur Willebrand. Au cours de l’activation des plaquettes par la thrombine, celle-ci clive la GPV et libère dans le plasma un fragment soluble dosable par technique ELISA. La GPV soluble est un marqueur de thrombose qui a donc la particularité d’être hautement spécifique de l’activation des plaquettes par la thrombine. Les premières études cliniques utilisant le dosage de la GPV soluble montrent que ses taux plasmatiques sont significativement augmentés au cours des thromboses artérielles aiguës comme l’infarctus du myocarde ou l’accident vasculaire cérébral ischémique et au cours des états à risque thrombotique comme l’athérosclérose ou la fibrillation auriculaire. Ces résultats encourageants permettent de proposer la GPV soluble comme un outil d’analyse des mécanismes de thrombose in vivo avec des retombées cliniques potentielles.
Laser Scattering From Multi-Scale Surfaces (1985)

We outline the results of surface profile measurements which suggest that many solid surfaces might realistically be modelled as multi-scale or fractal in nature. Experimental results of scattering radiation from such a well characterised fractal surface are presented and show a strikingly different behaviour to that expected from smoothly varying single-scale surfaces.
Two distinct activation states of plasmacytoid dendritic cells induced by influenza virus and CpG 1826 oligonucleotide (2007)

There is growing evidence that plasmacytoid dendritic cells (pDC) are involved in the innate recognition of various microbes. However, the precise consequences of pathogen recognition on pDC activation and function are incompletely understood. Using a novel transgenic mouse model that facilitates the isolation of highly pure pDC populations, we found that influenza virus PR/8, a TLR7 ligand, and CpG 1826 oligonucleotide, a TLR9 ligand, induced surprisingly divergent activation programs in these cells. pDC stimulated with PR/8 produced large amounts of type I IFNs, and CpG 1826-stimulated pDC expressed higher levels of costimulatory molecules and proinflammatory cytokines and induced stronger proliferation of T cells. Transcriptome analysis uncovered the differential regulation in pDC of 178 and 1577 genes by PR/8 and CpG 1826, respectively. These differences may relate to the activation of discrete signaling pathways, as evidenced by distinct ERK1/2 and p38 MAPK phosphorylation kinetics. Finally, pDC isolated ex vivo during PR/8 infection or after i.v. CpG 1826 injection resembled their in vitro counterparts, corroborating that these cells can adopt specialized phenotypes in vivo. Thus, pDC display remarkable functional flexibility, which emphasizes their versatile functions in antimicrobial immunity and inflammatory processes.
Atomic Force Microscopy Study of Forces between a Silica Sphere and an Oxidized Silicon Wafer in Aqueous Solutions of NaCl, KCl, and CsCl at Concentrations up to Saturation (2013)

This paper describes the measured forces between a spherical silica particle and a planar oxidized silicon wafer in NaCl, KCl, and CsCl aqueous solutions using an atomic force microscope (AFM). The magnitudes of measured forces are sensitive to electrolyte type and concentration over a broad range of 0.01–4 M under study. Increasing NaCl and KCl concentrations finds the suppression of repulsion at low concentrations, the appearance of attraction at an intermediate concentration, and the suppression of the attraction at high concentrations. In contrast, no attractions were detected for CsCl solutions except at 0.5 M, and increasing the concentration would lead to suppression of repulsion at the low concentration range and enhancement of repulsion at the high concentration range. The deviation between the measured total force and the calculated double-layer repulsion can be represented in the form of a power law incorporating an effective Hamaker constant (Aeff) and an offset separation distance.
Palladium(0) Complex-Catalyzed Debrominative Coupling of (Tribromomethyl)- and (Dibromomethyl)benzenes to Diarylacetylenes and 1,2-Diarylethenes (1995)

Palladium(0)-triphenylphosphine complex-catalyzed debrominative coupling reaction of (tribromomethyl)benzenes gave diarylacetylenes or a mixture of (E)- and (Z)-α,β-dibromostilbenes depending upon the substrate and the solvent being used. On the other hand, (dibromomethyl)benzenes afforded (E)-stilbenes selectively under the same reaction conditions.
Guiding Principles for Tactile Technology: Implications from Theory and Empirical Findings (2006)

There is an extensive literature on tactile interfaces and their overall importance to human-computer interaction is increasing. In this presentation we critically examine the psychological, computer science, engineering, and human factors literatures for tactile devices. Two major classes of principles emerge: those taken directly from authors' publications and those synthesized from the literature. Over 800 specific principles emerged from our work. We developed a structure for organizing the principles and offer the principles for specific guidance to researchers and practitioners.
Parametric studies of the thermal trap flat plate collector (1977)

The thermal trap effect, or the selective surface-like behavior of some transparent materials was investigated both theoretically and experimentally for a flat plate solar energy collector. A comprehensive computer simulation of the thermal trap collector was developed in order to study the effects upon performance of the various elements of the collector. A comparison of theoretically predicted performance to actual experimental performance for one version of the collector already under test at New Mexico State University proved the simulation to be very accurate. Subsequent parametric studies using the simulation indicated that the critical parameters were the thickness of the trap material and the presence or absence of a cover glazing. Therefore, four test collectors were built in which trap material and cover glazing were removable, and a series of experiments were run for trap materal thicknesses of 1/8'', 1/4'', 1/2'', 3/4'', 1'' and 1 1/2'' with and without cover glazing.
