Plasticization of PEDOT:PSS by Common Additives for Mechanically Robust Organic Solar Cells and Wearable Sensors (2014)

Despite the ubiquity of poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) in applications demanding mechanical flexibility, the effect on the mechanical properties of common additives—i.e., dimethylsulfoxide (DMSO), Zonyl fluorosurfactant (Zonyl), and poly(ethyleneimine) (PEI)—has not been reported. This paper describes these effects and uses plasticized films in solar cells and mechanical sensors for the detection of human motion. The tensile moduli of films spin‐coated from solutions containing 0%, 5%, and 10% DMSO and 0.1%, 1%, and 10% Zonyl (nine samples total) are measured using the buckling technique, and the ductility is inferred from measurements of the strain at which cracks form on elastic substrates. Elasticity and ductility are maximized in films deposited from solutions containing 5% DMSO and 10% Zonyl, but the conductivity is greatest for samples containing 0.1% Zonyl. These experiments reveal enlargement of presumably PEDOT‐rich grains, visible by atomic force microscopy, when the amount of DMSO is increased from 0% to 5%. PEI—which is used to lower the work function of PEDOT:PSS—has a detrimental effect on the mechanical properties of the PEDOT:PSS/PEI bilayer films. Wearable electronic sensors employing PEDOT:PSS films containing 5% DMSO and 10% Zonyl are ­fabricated, which exhibit detectable responses at 20% strain and high mechanical robustness through elastic deformation.
TAYLOR DISPERSION IN CONDUITS OF LARGE ASPECT RATIO† (1987)

The Taylor dispersion coefficient D¯C (above and beyond the purely molecular contribution D) arising during Poiseuille-like flow through noncircular cylindrical ducts of large aspect ratio (but otherwise arbitrary cross section) is theoretically calculated. Our study is motivated by an attempt to rationalize the remarkable fact that D¯C for a rectangular duct does not reduce to its well-known flat-plate value, D¯ ∞ C = 202H2/105D, in the limit where the aspect ratio tends to infinity [V¯ = mean velocity in duct, H = distance between plates]. Slender-body theory is used to express both the fluid velocity and concomitant Taylor dispersion fields as perturbation expansions in the small parameter ε = (aspect ratio)−1 ≪ 1, following which D¯C is computed to the lowest order in e. This dispersivity is found to scale with the longer of the two characteristic duct dimensions for all cross sections save the rectangular, for which D¯C scales with the shorter dimension. This surprising result is explained by noting that, in either case, D¯C scales with that cross-sectional dimension along which the lateral fluid velocity gradients are greatest in extent. As an easily claimed bonus, we also calculate the Hagen-Poiseuille pressure-drop/flow-rate coefficient for these high aspect ratio ducts.

Peptoid–Peptide Hybrid Ligands Targeting the Polo Box Domain of Polo‐Like Kinase 1 (2012)

We replaced the amino terminal Pro residue of the Plk1 polo-box-domain-binding pentapeptide (PLHSpT) with a library of N-alkyl-Gly "peptoids", and identified long-chain tethered phenyl moieties giving greater than two-orders-of-magnitude affinity enhancement. Further simplification by replacing the peptoid residue with appropriate amides gave low-nanomolar affinity N-acylated tetrapeptides. Binding of the N-terminal long-chain phenyl extension was demonstrated by X-ray co-crystal data.
First description of eosinophilic esophagitis using confocal laser endomicroscopy (with video) (2011)

Confocal laser endomicroscopy enables in vivo microscopic imaging of the mucosal layer of the gut at a subcellular resolution [1]. Various studies have addressed the potential of endomicroscopy for the in vivo diagnosis of esophageal squamous cell carcinoma, Barrett’s esophagus, and esophageal adenocarcinoma [2] [3] [4]. Currently, no data are available on the utility of endomicroscopy for the in vivo diagnosis of eosinophilic esophagitis.
Complexity Measures of Voice Recordings as a Discriminative Tool for Parkinson’s Disease (2019)

In this paper, we have investigated the differences in the voices of Parkinson's disease (PD) and age-matched control (CO) subjects when uttering three phonemes using two complexity measures: fractal dimension (FD) and normalised mutual information (NMI). Three sustained phonetic voice recordings, /a/, /u/ and /m/, from 22 CO (mean age = 66.91) and 24 PD (mean age = 71.83) participants were analysed. FD was first computed for PD and CO voice recordings, followed by the computation of NMI between the test groups: PD-CO, PD-PD and CO-CO. Four features reported in the literature-normalised pitch period entropy (Norm. PPE), glottal-to-noise excitation ratio (GNE), detrended fluctuation analysis (DFA) and glottal closing quotient (ClQ)-were also computed for comparison with the proposed complexity measures. The statistical significance of the features was tested using a one-way ANOVA test. Support vector machine (SVM) with a linear kernel was used to classify the test groups, using a leave-one-out validation method. The results showed that PD voice recordings had lower FD compared to CO (<i>p</i> < 0.008). It was also observed that the average NMI between CO voice recordings was significantly lower compared with the CO-PD and PD-PD groups (<i>p</i> < 0.036) for the three phonetic sounds. The average NMI and FD demonstrated higher accuracy (>80%) in differentiating the test groups compared with other speech feature-based classifications. This study has demonstrated that the voices of PD patients has reduced FD, and NMI between voice recordings of PD-CO and PD-PD is higher compared with CO-CO. This suggests that the use of NMI obtained from the sample voice, when paired with known groups of CO and PD, can be used to identify PD voices. These findings could have applications for population screening.
Prediction and Identification of T Cell Epitopes in the H5N1 Influenza Virus Nucleoprotein in Chicken (2012)

T cell epitopes can be used for the accurate monitoring of avian influenza virus (AIV) immune responses and the rational design of vaccines. No T cell epitopes have been previously identified in the H5N1 AIV virus nucleoprotein (NP) in chickens. For the first time, this study used homology modelling techniques to construct three-dimensional structures of the peptide-binding domains of chicken MHC class Ι molecules for four commonly encountered unique haplotypes, i.e., B4, B12, B15, and B19. H5N1 AIV NP was computationally parsed into octapeptides or nonapeptides according to the peptide-binding motifs of MHC class I molecules of the B4, B12, B15 and B19 haplotypes. Seventy-five peptide sequences were modelled and their MHC class I molecule-binding abilities were analysed by molecular docking. Twenty-five peptides (Ten for B4, six for B12, two for B15, and seven for B19) were predicted to be potential T cell epitopes in chicken. Nine of these peptides and one unrelated peptide were manually synthesized and their T cell responses were tested in vitro. Spleen lymphocytes were collected from SPF chickens that had been immunised with a NP-expression plasmid, pCAGGS-NP, and they were stimulated using the synthesized peptides. The secretion of chicken IFN-γ and the proliferation of CD8(+) T cells were tested using an ELISA kit and flow cytometry, respectively. The significant secretion of chicken IFN-γ and proliferation of CD8(+) T lymphocytes increased by 13.7% and 11.9% were monitored in cells stimulated with peptides NP(89-97) and NP(198-206), respectively. The results indicate that peptides NP(89-97) (PKKTGGPIY) and NP(198-206) (KRGINDRNF) are NP T cell epitopes in chicken of certain haplotypes. The method used in this investigation is applicable to predicting T cell epitopes for other antigens in chicken, while this study also extends our understanding of the mechanisms of the immune response to AIV in chicken.
Think Marketing (1986)

Marketing is concerned with getting the right product to the right customer at the right price. It is not just a fancy word for 'selling'. It is not synonymous with 'advertising' or 'sales promotion': nor is it merely a data-collecting, number-processing and planning activity.
Longitudinally dispersive profilometer (1995)

A non-contacting optical profilometer is presented based on the principle of focus multiplexing by wavelength encoding due to a phase Fresnel lens. The decoding is performed by lateral dispersion. The surface profile is reconstructed after automatic point by point scanning with submicrometre height resolution.
High-indium-content InGaAs metal-oxide-semiconductor capacitor with amorphous LaAlO3 gate dielectric (2007)

The structure and electrical properties of LaAlO3∕n-In0.53Ga0.47As metal-oxide-semiconductor capacitors deposited by molecular-beam epitaxy were investigated. Transmission electron microscopy revealed a sharp interface between the dielectric and InGaAs. Postdeposition annealing at 440–500°C significantly reduced the capacitive equivalent thickness and frequency dispersion. A hysteresis of 15mV–0.1V, a dielectric permittivity of 17±1, and a dielectric strength of ∼4.3MV∕cm were measured. Additionally, a high loss in the parallel conductance and gate-bias independence in the inversion region was observed, implying the fast generation rate of minority carriers in In0.53Ga0.47As.
Hepato-protective potential of carotenoid meso-zeaxanthin against paracetamol, CCl4 and ethanol induced toxicity. (2011)

Hepato-protective potential of carotenoid meso-zeaxanthin [(3R, 3'S)-beta, beta-carotene-3, 3'-diol] was studied using in vivo rat models. Paracetamol (3 g/kg body wt, orally), 20% ethanol (7.5 g/kg body wt, orally) and CCl4 (2.5 ml /kg, ip) were used as hepato toxins. Levels of marker enzymes of hepatic injury such as serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase and alkaline phosphatase, and serum bilirubin, which were drastically elevated by these hepato toxins were significantly decreased by meso-zeaxanthin pretreatment in a dose-dependent manner. Oxidative stress markers, tissue lipid peroxidation, conjugated dienes and tissue hydroperoxides, were high in the paracetamol treated control group animals, which were lowered by meso-zeaxanthin administration. Level of glutathione and antioxidant enzymes, superoxide dismutase, catalase and glutathione peroxidase, in liver tissue was increased by meso-zeaxanthin pretreatment compared to control group during alcohol and CCl4 induced hepatotoxicity. Hydroxyproline, an indicator of fibrosis in liver tissue, decreased remarkably by meso-zeaxanthin administration despite its notable elevation in ethanol treated rats. Histopathological analysis of liver tissue showed the hepatoprotective potential of meso-zeaxanthin.
Deposition of BaTiO3 Thin Films by ArF Excimer Laser Ablation. (1993)

BaTiO3 films have been deposited on a quartz substrate at various substrate temperatures by the ArF excimer laser ablation technique. Crystallization of the film deposited at substrate temperatures as low as 300°C was confirmed by X-ray diffraction analysis. The expansion velocities of the laser plume and the ablated species in the plume have also been investigated by time-resolved optical observation and spectroscopy.
Perceptual evaluation of articulatory movement recovered from acoustic data (1994)

A method involving task dynamics and a genetic algorithm [see McGowan, Speech Commun. 14, 19–48 (1994)] was used to recover articulation from the speech acoustics of a human subject. Six utterances from a single subject were chosen to test the applicability of the proposed method to human beings: /ga/, /gi/, /da/, /di/, /ba/, and /bi/. The first three formant trajectories of the natural utterances were extracted and used to represent the acoustic data. A genetic algorithm was used in constrained optimization of task-dynamic parameters applied to the Haskins Laboratories articulatory synthesizer, ASY. The articulatory movements recovered in this manner were assessed using perceptual tests of the resulting speech generated by ASY and by a visualization of the resulting ASY articulation.
La forma de mosaico del cine digital. Hollywood digital y la poética del entretenimiento. Segunda parte (2008)

The residents in Hubei and Henan Provinces have generally good KAP related to COVID-19, and the online platforms plays a positive role to in circulating epidemic-related information. It is essential to further increase the supply of the protective materials and pay more attention to the mental health of the residents during the pandemic, and psychological counseling and psychological protection should be provided if necessary.
Membrane glycopeptides from virus-transformed hamster fibroblasts and the normal counterpart (1979)

Comparisons of membrane glycopeptides from baby hamster kidney fibroblasts (BHK21/C13) and a clone transformed by Rous sarcoma virus (C13/B4) were made by using cells metabolically labeled with radioactive D-glucose and L-fucose. Most of the glycopeptides were metabolically labeled with both the general and the specific glycoprotein precursors. The glycopeptides obtained from the cell surface by controlled trypsinization were representative of the surface membrane as shown by comparing them with those of purified membrane preparations. The trypsin-removable glycopeptides from both cell types were further processed and examined by successive chromatography on Sephadex G-50 and DEAE-cellulose. The chromatographic distribution patterns showed that each cell type had glycopeptides of similar characteristics, although the proportions of the glycopeptides differed dramatically between the two cell types. After transformation there was an increase in the larger, more highly charged glycopeptides. This was verified by the increased sialic acid content in these glycopeptides. Some of the glycopeptides were homogeneous after the size and charge separations, since a variety of procedures did not separate them further. The apparent homogeneity and reasonably few species obtained may be due to the methods of isolation, with the procedures selecting particular glycopeptides from the external portion of the membrane. These results corroborate the concept and show for the first time that virus transformation is accompanied by an increase in certain species of glycopeptides rather than de novo synthesis.
Cathodoluminescence and polarization studies from individual dislocations in diamond (1984)

Abstract A cathodoluminescence detector attached to a transmission electron microscope has been used to record visible optical-emission spectra from individual dislocations of known type in type IIb diamond over a range of temperatures. The polarization of the emission has also been determined from individual dislocations and this information correlated with the type and degree of dissociation of the dislocations. It was found that the dislocation emission at 435 nm was polarized along the dislocation line (independent of the Burgers vector) and had maximum intensity at 170 K. The emission spectrum was independent of dislocation type, and showed a broad (0·416 eV f.w.h.m.) band. All luminescent dislocations were dissociated, and one non-luminescent dislocation was found which was undissociated within the resolution of the weak-beam technique (∼ 15 Å). Non-luminescent dissociated dislocations were also found. Curved dislocations were less luminescent than straight ones. A one-dimensional donor-acceptor model is suggested as being consistent with all these findings, which rule out several other proposed mechanisms.
The Li3PO4/Al bilayer: An efficient cathode for organic light emitting devices (2009)

In this contribution an efficient cathode material for organic light emitting diodes (OLEDs) is introduced consisting of a thin layer of the metal salt lithium phosphate (Li3PO4) deposited between the organic semiconductor and an Al cathode. The bilayer cathode Li3PO4/Al enables a device performance of small molecule based OLEDs competitive to the benchmark cathode LiF/Al. While current densities and luminances of both systems are alike, the use of Li3PO4 substantially increases the device lifetime. It will be shown that the improved device characteristics can be ascribed to a stably enhanced electron injection. We demonstrate that neither a field enhancement across the Li3PO4 layer due to accumulated holes nor a possible charge transfer doping by the Li3PO4 is the reason for the improved electron injection. Investigation of the Li3PO4/Al interface by Kelvin probe techniques disclosed a work function lowering of the cathode that facilitates electron injection and finally explains the improvement in performance of respective organic light emitting diodes.
Ubiquitous Data Accessing Method in IoT-Based Information System for Emergency Medical Services (2014)

The rapid development of Internet of things (IoT) technology makes it possible for connecting various smart objects together through the Internet and providing more data interoperability methods for application purpose. Recent research shows more potential applications of IoT in information intensive industrial sectors such as healthcare services. However, the diversity of the objects in IoT causes the heterogeneity problem of the data format in IoT platform. Meanwhile, the use of IoT technology in applications has spurred the increase of real-time data, which makes the information storage and accessing more difficult and challenging. In this research, first a semantic data model is proposed to store and interpret IoT data. Then a resource-based data accessing method (UDA-IoT) is designed to acquire and process IoT data ubiquitously to improve the accessibility to IoT data resources. Finally, we present an IoT-based system for emergency medical services to demonstrate how to collect, integrate, and interoperate IoT data flexibly in order to provide support to emergency medical services. The result shows that the resource-based IoT data accessing method is effective in a distributed heterogeneous data environment for supporting data accessing timely and ubiquitously in a cloud and mobile computing platform.
Nocturnal leg muscle cramps (1980)

NOCTURNAL leg muscle cramping (NLMC) is a frequent complaint heard by physicians in all specialties, from patients of all age groups, though probably most commonly in the elderly. Such muscle cramping usually involves the calf muscles (gastrocnemius or soleus) or the small intrinsic muscles of the sole of the foot. Both muscle groups are functionally similar, and the following discussion is applicable to both. Leg cramps usually occur at night in bed and are precipitated by random muscle contraction or, more frequently, by voluntary stretching movements of the lower extremities. They are exquisitely painful and a cause for much distress and anxiety. Nocturnal leg muscle cramping is to be sharply differentiated from leg cramps that occur from exercise such as walking or running. These can indicate an underlying pathologic process, such as the claudication of peripheral vascular insufficiency or the "pseudoclaudication" of radiculopathy, especially secondary to lumbar spinal stenosis.

Water Immiscible Solvent Based Immunoassay (1997)

A competitive monoclonal antibody-based immunoassay which quantifies a hydrophobic hapten (Rx) in water immiscible solvents, obviating the need of a pre-extraction step, has been developed. Approximately linear dose response profiles of analyte, over the range 1-20 ugml-1 in the hydrophobic solvents, hexane, toluene and xylene were obtained. UV spectrophotometric analyses of Rx dosed hexane confirm the phenomenon of antibody-mediated transfer of analyte from the organic to the aqueous milieu. Preliminary data on the effect of water immiscible solvents on the immunoreactivity of a monoclonal antibody in free solution are presented. The potential industrial applications of water immiscible solvent based immunoassays are discussed.
ELECTRIC PROPERTIES OF CONNECTIONS BY ANISOTROPIC CONDUCTIVE FILM (1995)

Anisotropic conductive film (ACF) consists of conductive particles and an adhesive. It is used to connect the tape automated bonding (TAB) to the liquid crystal display (LCD) panel.Today, surface mount technologies are essential for the miniaturization of electric products. We investigate the electric properties of connections by ACF.This paper introduces different kinds of reliability and connection resistance data and reports on the role of conductive particles.
On the Equivalence of Major Variable-Step-Size MPPT Algorithms (2016)

Functional equivalence of three nonmodel-based variable-step-size maximum power point tracking (MPPT) algorithms is revealed in this paper by establishing general closed-loop controller-plant structure of corresponding MPPT control loops, allowing us to formulate the problem as a typical stabilization task. The MPPT loop plants may be separated into three main components, two of which are similar and the third one, namely stabilization function estimator, is the main reason for the performance differences of the discussed methods in case the MPPT loop controllers are alike. It is shown that in case the estimator convergence rate is much faster than the MPPT loop bandwidth, similar low-frequency performance may be expected by utilizing any of the three methods.
Accuracy of reported family histories of essential tremor (1996)

We studied the accuracy of reported family histories of essential tremor (ET) by questioning the patients in our clinic and subsequently by mail and phone. For individuals who continued to report a negative family history, we mailed a screening questionnaire to their first-degree relatives to further ascertain the presence of ET. On initial assessment, 67.7% of patients reported a positive family history of ET, but following all assessments, 96.0% of patients had a positive family history. We conclude that a negative family history of ET is often inaccurate, and that ET is primarily a hereditary disease.
