A Printed Carbon Nanotube Sensor on a Flexible Substrate (2014)

Printing becomes an emerging manufacturing technology for mechanics, electronics, and consumer products. Carbon nanotubes have recently been used as a material for sensors and electrodes due to their unique electrical and mechanical properties. Printed electrodes and conductive traces particularly offer versatility of fabricating low-cost, disposable, and flexible sensors and devices. While screen-printing has been a conventional method for printing conductive traces and electrodes, inkjet-printing recently attracts a wide attention due to its unique advantages including no template requirement, rapid printing at low cost, on-demand printing capability, and precise control of the printed material. Computer generated conductive trace or electrode patterns can simply be printed on a flexible substrate with proper conductive ink. However, for inkjet-printing of nanotubes to form conductive traces and electrodes, there are few challenges that need to be addressed. One is nanotube dispersion in an ink base solution while others include adjusting surface tension and controlling viscosity of the ink and treating the surface of the printing substrate. This work presents carbon nanotube ink preparation and its demonstration in chemical sensing along with our recent achievements. It is essential to disperse carbon nanotubes to make a carbon nanotube ink. In our previous work, we have demonstrated an inkjet printed electrochemical sensor using an office HP inkjet printer and a carbon nanotube ink. Sodium dodecyl sulfate (SDS) was used as a dispersant and a surfactant in preparing the carbon nanotube ink. It should be noted that that a ratio of SDS concentration and carbon nanotube concentration would be an important factor determining the sheet resistance of a printed carbon nanotube pattern. A preliminary test result confirmed that there would be an optimum SDS:CNT ratio. For flexible sensor applications, sheet resistance change of the printed carbon nanotube patterns on a flexible substrate was measured for varying curvatures of the substrate. For a curvature up to 0.36 cm -1 , the sheet resistance increase was less than 2.5% showing that the printed carbon nanotube patterns could be used for a flexible and printed sensor. Using the developed technologies, a fully printed carbon nanotube sensor on a flexible substrate will be demonstrated for chemical and biological sensing.
Dipolar Glass Behaviour in Mixed CuInP2(S0.7Se0.3)6Crystals (2005)

The dielectric spectrum of mixed CuInP2(S0.7Se0.3)6 crystals was investigated. The calculated distribution of relaxation times confirms glassy behaviour and the maxima of the distribution of the relaxation times follow Vogel-Fulcher law with parameters: activation energy E A = 9.4 · 10−2 eV, dipole freezing temperature T 0 = 21.9 K and attempt frequency υ0 = 1/(2π τ0) = 0.149 THz. From all presented results we see, that CuInP2(S0.7Se0.3)6 crystal shows typical dipolar glass dielectric dispersion and we may conclude that this crystal belongs to new family of materials that exhibits a dipolar glass behavior.

Ion implanter and Activation Annealing for SiC devices (2018)

Ion implanter process for SiC devices needs much longer time compared with Si process. Therefore implantation process optimization is important to reduce cost. In this paper, implantation temperature that affects process time is discussed. And activation conditions after implantation is also discussed.
Translating ISO 12083 Mathematical Markup for Electronic Documents (1995)

In this paper, we describe a general translation tool that can transform tagged text into arbitrary output formats. Specifically, we describe how OCLC makes scientific documents containing mathematical markup available on the World Wide Web. The translation capabilities we developed to do this help realize the potential of the Standard Generalized Markup Language (SGML) to provide users with a single, non-proprietary document representation that can be translated on demand to other output formats. This enables publishers who target the WWW as a delivery medium to use the latest advances in HTML without constant revision of their document archives.
New high-rate sputtering-type electron cyclotron resonance microwave plasma using an electric mirror (1989)

High-rate sputtering is achieved by means of new electron cyclotron resonance microwave plasma employing sputtering using an electric mirror. This apparatus consists of both planar and cylindrical targets. Microwave power is perpendicularly or obliquely introduced into the resonance chamber. High-density plasma of 1012 cm−3 is generated. The reflected electrons oscillating between the two targets play a major role in generating the dense plasma, i.e., as a beam-plasma interaction. Both insulator and conductor films can be continuously deposited by this sputtering method at high rates under low gas pressures of 10−2 Pa. Al, Mo, and Fe films are deposited at rates above 2000 Å/min.
Oxidative-addition reactions of [W2(η-C5H4R)2X4](R = Prior Me; X = Cl or Br): reversible addition of dihydrogen to a tungsten–tungsten triple bond and X-ray crystal structures of [W2(η-C5H4Pri)2Cl4(µ-H)(µ-PPh2)] and [W2(η-C5H4Pri)2Cl3(µ-Cl)(µ-H)(µ-PPh2)(PMe3)] (1991)

The unsupported WW bond of [W2(η-C5H4R)2X4](X = Cl, R = Pri1a or Me 1b; X = Br, R = Pri2) readily undergoes oxidative-addition reactions with HY [Y = H, Cl, SR′(R′= Me, Et, Pri, Ph or But), or PPhR′(R′= H or Ph)] to afford the corresponding derivatives [W2(η-C5H4R)2X4(µ-H)(µ-Y)] in good yields. For 1a the addition of H2 is reversible with reductive elimination occurring readily at ca. 50 °C under reduced pressure. The µ-phosphido complex [W2(η-C5H4Pri)2Cl4(µ-H)(µ-PPh2)] has been crystallographically characterised and possesses a WW double bond [2.6558(3)Å]. The µ-thiolato complexes [W2(η-C5H4R)2Cl4(µ-H)(µ-SR′)] are fluxional and undergo inversion at the µ-S atom; ΔG‡ values for this process have been determined and increase in the order R′= But < Pri < Ph < Et < Me. The µ-chloro complexes [W2(η-C5H4R)2Cl4(µ-Cl)(µ-H)] undergo a different fluxional process which effectively involves rotation of the (µ-Cl)(µ-H) fragment about the W–W vector. The complexes [W2(η-C5H4Pri)2Cl4(µ-H)(µ-Y)](Y = H or PPh2) react with PMe3 to give the corresponding adducts [W2(η-C5H4Pri)2Cl3(µ-Cl)(µ-H)(µ-Y)(PMe3)], the X-ray crystal structure of the µ-phosphido complex (Y = PPh2) having been determined. In contrast, treatment of [W2(η-C5H4Pri)2Cl4(µ-H)(µ-Y)](Y = Cl or SR′) with an excess of PMe3 affords the mononuclear complex [W(η-C5H4Pri)Cl(PMe3)3].

Synergism in low level vision (2003)

Guiding image segmentation with edge information is an often employed strategy in low level computer vision. To improve the trade-off between the sensitivity of homogeneous region delineation and the over-segmentation on of the image, we have incorporated a recently proposed edge magnitude/confidence map into a color image segmenter based on the mean shift procedure. The new method can recover regions with weak but sharp boundaries and thus can provide a more accurate input for high level interpretation modules. The edge detection and image segmentation (EDISON) system, available for download, implements the proposed technique and provides a complete toolbox for discontinuity preserving filtering, segmentation and edge detection.
Heteromeric and Homomeric Interactions Correlate with Signaling Activity and Functional Cooperativity of Smad3 and Smad4/DPC4 (1997)

Homologs of Drosophila Mad function as downstream mediators of the receptors for transforming growth factor beta (TGF-beta)-related factors. Two homologs, the receptor-associated Smad3 and the tumor suppressor Smad4/DPC4, synergize to induce ligand-independent TGF-beta activities and are essential mediators of the natural TGF-beta response. We now show that Smad3 and Smad4 associate in homomeric and heteromeric interactions, as assessed by yeast two-hybrid and coimmunoprecipitation analyses. Heteromeric interactions are mediated through the conserved C-terminal domains of Smad3 and Smad4. In Smad3, the homomeric interaction is mediated by the same domain. In contrast, the homomeric association of Smad4 requires both the N-terminal domain and the C-terminal domain, which by itself does not homomerize. Mutations that have been associated with impaired Mad activity in Drosophila or decreased tumor suppressor activity of Smad4/DPC4 in pancreas cancer, including a short C-terminal truncation and two point mutations in the conserved C-terminal domains, impair the ability of Smad3 and Smad4 to undergo homo- and heteromeric associations. Analyses of the biological activity of Smad3 and Smad4 and their mutants show that full signaling activity correlates with their ability to undergo efficient homo- and heteromeric interactions. Mutations that interfere with these interactions result in decreased signaling activity. Finally, we evaluated the ability of Smad3 or Smad4 to induce transcriptional activation in yeast. These results correlate the ability of individual Smads to homomerize with transcriptional activation and additionally with their biological activity in mammalian cells.
The general solution to the Bloch equation with constant rf and relaxation terms: Application to saturation and slice selection (1993)

The general solution to the Bloch equation in the rotating frame which includes the effects of relaxation during a constant amplitude, off‐resonance rf field has been developed. The solution is used to monitor the transient approach to steady‐state saturation levels during off‐resonance irradiation applied continuously or in pulses to systems with arbitrary relaxation rates. The time course of the magnetization during amplitude modulated rf pulses is followed with the general solution and the transverse relaxation time dependence of typical slice profiles is examined. The calculations serve to illustrate the generality of the solution. A thorough discussion of various computational concerns is provided.
OS0506 Joule Heat Joining of Very Thin Metallic Wires in Scanning Electron Microscope (2009)

The joining of two extremely thin Pt wires has been successful in air environment and the parameter that govems the melting phenomenon at the contact of the wires has been reported. The joining of Pt wires in scanning electron microscope is achieved with a current lower than that in air environment due to the adiabatic effect under vacuum environment. The difference between the joining conditions of the air and the vacuum environments is calibrated by a thermal function, and based on this two Pt wires can be joined together without relying on the surrounding environmental condition. The melting and solidification processes at the contacting portion of the wires are also observed by in-situ observation with scanning electron microscope.
Extraction liquide-liquide et solide-liquide des lanthanides par des β-dicétones hétérocycliques et des ligands N-donneurs,libres ou immobilisés sur des silices mésostructurées (2004)

L'extraction liquide-liquide de terres rares trivalentes Ln(III) (Ln : La, Eu, Lu), a partir de milieux aqueux nitriques, par la bis-acylpyrazolone 1,12-bis(1´-phenyl-3´-methyl-5´-hydroxy-4´-pyrazolyl)-dodecane-1,12-dione (HL-(CH2)10-LH) a ete etudiee. L'extraction est d'autant plus efficace que le numero atomique de l'element a extraire est eleve (La < Eu < Lu). Elle se fait a plus bas pH que l'extraction par les 4-acyl-5-hydroxypyrazoles simples (HL). La presence de la 2,4,6-tri(2-pyridyl)-1,3,5-triazine, TPTZ, agent de solvatation de type 3N-donneur, provoque un effet synergique important ; TPTZ impose l'ordre d'extraction synergique : La < Lu < Eu. L'extraction solide-liquide des Ln(III) par des silices mesostructurees dopees par les extractants utilises en extraction liquide-liquide a ete egalement etudiee. Les silices dopees ont ete synthetisees a basse temperature selon le procede sol-gel en utilisant les micelles de bromure de cetyltrimethylammonium, CTAB, comme agent pour structurer la porosite (syntheses de type MCM-41). Elles ont ete caracterisees par porosimetrie a l'azote, diffraction des rayons X, microscopie electronique a balayage MEB, microscopie electronique a transmission MET et granulometrie laser. Les silices dopees sont destructurees par rapport aux silices lamellaires obtenues quand le melange synthetique ne contient pas d'extractant ; cependant, le materiau dope conserve une grande surface specifique (990 a 1230 m2. G-1) et reste mesoporeux. L'extraction solide-liquide par les silices dopees par HL ou HL-(CH2)10-LH est plus efficace a bas pH que l'extraction liquide-liquide ; en outre, elle est plus rapide. La stoechiometrie du complexe extrait et la capacite d'extraction de l'europium par HL-(CH2)10-LH sont comparables pour les extractions solide-liquide et micellaire. La stoechiometrie des bis-acylpyrazolonates, extraits par les trois techniques differentes, est fonction de la technique d'extraction utilisee, mais aussi des concentrations initiales des especes chimiques dans chacune des phases. Pour l'europium, avec une silice dopee par HL-(CH2)10-LH et TPTZ, on observe une synergie d'extraction moderee. Le rapport metal/acylpyrazolonate, dans le complexe extrait par la silice dopee par HL-(CH2)10-LH seule (1:2) Eu(L-(CH2)10-L)(L-(CH2)10-LH), differe de celui qui existe dans le complexe synergique (1:3) Eu(L-(CH2)10-LH)3(TPTZ). La capacite d'extraction de l'europium est de 0,18 mmol/g : 200 fois plus importante que celles des silices impregnees.
Comparison of acute elastic recoil between the SAPIEN‐XT and SAPIEN valves in transfemoral–transcatheter aortic valve replacement (2014)

The SAPIEN XT valves had significantly greater acute recoil after deployment compared to the SAPIEN valves. Implications of this difference in acute recoil on valve performance need to be investigated in future studies.

The Error of Representation in the Ensemble Kalman Filter (2017)

We develop techniques needed to account for representation error in data assimilation. Representation error is a characterization of the mismatch between numerical models and the physical processes they are approximating. This mismatch can occur due to computational constraints or due to limited understanding of certain physical processes. In this paper we study the relationship of low resolution forecasts with unresolved processes to high resolution forecasts with fully resolved processes. We begin with a discussion of representation error and then discuss regularization techniques used to build a map from high resolution forecasts to low resolution forecasts. We conclude with a demonstration of these techniques using the Korteweg-DeVries nonlinear wave model.

Correlation of Foraminal Area and Response to Cervical Nerve Root Injections (2015)

Measurement of neuroforaminal areas on MRI may represent a useful pre-procedural technique to predict which patients with symptoms of cervical radiculopathy secondary to foraminal stenosis are likely to respond to selective nerve root injections. The predictive ability appears to be limited to those patients with severe stenosis and was less useful in those patients with moderate or mild stenosis.
VEGF Receptor-2 (Flk-1) Overexpression in Mice Counteracts Focal Epileptic Seizures (2012)

Vascular endothelial growth factor (VEGF) was first described as an angiogenic agent, but has recently also been shown to exert various neurotrophic and neuroprotective effects in the nervous system. These effects of VEGF are mainly mediated by its receptor, VEGFR-2, which is also referred to as the fetal liver kinase receptor 1 (Flk-1). VEGF is up-regulated in neurons and glial cells after epileptic seizures and counteracts seizure-induced neurodegeneration. In vitro, VEGF administration suppresses ictal and interictal epileptiform activity caused by AP4 and 0 Mg(2+) via Flk-1 receptor. We therefore explored whether increased VEGF signaling through Flk-1 overexpression may regulate epileptogenesis and ictogenesis in vivo. To this extent, we used transgenic mice overexpressing Flk-1 postnatally in neurons. Intriguingly, Flk-1 overexpressing mice were characterized by an elevated threshold for seizure induction and a decreased duration of focal afterdischarges, indicating anti-ictal action. On the other hand, the kindling progression in these mice was similar to wild-type controls. No significant effects on blood vessels or glia cells, as assessed by Glut1 and GFAP immunohistochemistry, were detected. These results suggest that increased VEGF signaling via overexpression of Flk-1 receptors may directly affect seizure activity even without altering angiogenesis. Thus, Flk-1 could be considered as a novel target for developing future gene therapy strategies against ictal epileptic activity.
Chromatic and luminance sensitivity for skin and skinlike textures (2019)

Despite the importance of the appearance of human skin for theoretical and practical purposes, little is known about visual sensitivity to subtle skin-tone changes, and whether the human visual system is indeed optimized to discern skin-color changes that confer some evolutionary advantage. Here, we report discrimination thresholds in a three-dimensional chromatic-luminance color space for natural skin and skinlike textures, and compare these to thresholds for uniform stimuli of the same mean color. We find no evidence that discrimination performance is superior along evolutionarily relevant color directions. Instead, discriminability is primarily determined by the prevailing illumination, and discrimination ellipses are aligned with the daylight locus. More specifically, the area and orientation of discrimination ellipses are governed by the chromatic distance between the stimulus and the illumination. Since this is true for both uniform and textured stimuli, it is likely to be driven by adaptation to mean stimulus color. Natural skin texture itself does not confer any advantage for discrimination performance. Furthermore, we find that discrimination boundaries for skin, skinlike, and scrambled skin stimuli are consistently larger than those for uniform stimuli, suggesting a possible adaptation to higher order color statistics of skin. This is in line with findings by Hansen, Giesel, and Gegenfurtner (2008) for other natural stimuli (fruit and vegetables). Human observers are also more sensitive to skin-color changes under simulated daylight as opposed to fluorescent light. The reduced sensitivity is driven by a decline in sensitivity along the luminance axis, which is qualitatively consistent with predictions from a Von Kries adaptation model.

The test for hemoglobin and transferrin showed the highest sensitivity and specificity for colorectal neoplasia in the retrospective study. The sensitivity and specificity of this test were not so high in the prospective study, but they may be clinically applicable in the evaluation of patients with various nonspecific symptoms.

Copolymerization of Styrene and Methyl Methacrylate in the Presence of a Catalytic Chain Transfer Agent (1998)

Copolymerizations of styrene and methyl methacrylate have been performed using different monomer feed compositions in the presence of a catalytic chain transfer agent at 40 °C. Average chain transfer constants as a function of monomer feed composition were determined with the conventional Mayo procedure using both number (Mn) and weight (Mw) average molecular weights, and with the chain length distribution procedure using both high (ΛH) and peak (ΛP) molecular weight slopes. It is found that the average chain transfer constants determined from Mw and ΛP are generally very similar, with those obtained from Mn and ΛH being larger and smaller, respectively. The average chain transfer constants obtained from Mw and ΛP are compared with model predictions based upon both the terminal and penultimate unit models of free-radical copolymerization and are in satisfactory agreement. These two models are used to predict the fraction of propagating radicals with a terminal styrene unit, and it is found, similar to earlier studies reported in the literature, that this parameter is very sensitive to the penultimate model s values (in contrast to the average propagation rate coefficient), and a satisfactory agreement between model and experiment is obtained for sM = 2. This finding possibly suggests a complimentary route to measuring average propagation rate coefficients, for the determination of penultimate model s values.
