Abstract 172: tPA Variant tPA-A296-299 Prevents Impairment of Cerebral Autoregulation After Stroke Through LRP Dependent Increase in cAMP and p38 MAPK (2016)

Introduction: The sole FDA approved treatment for acute stroke is tissue type plasminogen activator (tPA). However, its brief therapeutic window and post-treatment complications markedly constrain its use. The limited efficacy of tPA may be explained in part by our finding that it potentiates impairment of cerebral autoregulation after stroke in pigs. Upregulation of JNK MAPK after thrombotic stroke contributes to tPA mediated impairment of autoregulation whereas p38 is protective. Vasodilation is mediated by elevation of cAMP. However, cAMP falls after stroke due to over activation of NMDA receptors (NMDA-Rs) by toxic levels of glutamate, which is exacerbated by tPA. Hypothesis: Wild type (wt) tPA can bind to either the lipoprotein-related receptor (LRP), which mediates vasodilation, or NMDA-Rs. We propose that wt tPA given after stroke primarily binds to NMDA-Rs, reduces cAMP, which impairs ability of cerebral vessels to vasodilate. tPA-A296-299, a variant that is fibrinolytic but cannot bind to NMDA-Rs, preferentially binds LRP, which increases cAMP and p38 and limits impairment of autoregulation after stroke. Methods: Anesthetized pigs equipped with a closed cranial window were used. Stroke was induced by photothrombosis, CBF determined by radiolabeled microspheres, and CSF cAMP and p38 determined by ELISA. Results: CBF was unchanged during hypotension (mean arterial pressure decreased by 45%) in sham animals. CBF was reduced in brain tissue surrounding the infarct and was reduced further during hypotension, indicating impairment of autoregulation. Autoregulation was further impaired by wt tPA which was prevented by MK801 and tPA-A296-299. Protection by tPA-A296-299 was blocked by anti LRP Ab, the LRP antagonist RAP, the p38 inhibitor SB 203580, but not by IgG. Stroke reduced CSF cAMP, which was reduced further by wt tPA, but augmented by tPA-A296-299. CSF p38 was unchanged by wt tPA, robustly increased by tPA-A296-299, and decreased by co-administered anti LRP Ab and RAP but not by IgG. Conclusions: tPA-A296-299 prevents impairment of cerebral autoregulation after stroke through LRP dependent increase in cAMP and p38.
Optical and Photophysical Properties of Indolocarbazole Derivatives (2006)

We present a study of the optical and photophysical properties of five ladder indolo[3,2-b]carbazoles, namely, M1, M2, M3, M4, and M5. The ground-state optimized structures were obtained by B3LYP/6-31G* density functional theory (DFT) calculations, whereas the optimization (relaxation) of the first singlet excited electronic state (S1) was performed using the restricted configuration interaction (singles) (RCIS/6-31G*) approach. The excitation to the S1 state does not cause important changes in the geometrical parameters of the compounds, as corroborated by the small Stokes shifts. The excitation and emission energies have been obtained by employing the time-dependent density functional theory (TDDFT). For all the compounds, excitation to the S1 state is weakly allowed, whereas the S2 <-- S0 electronic transition of each oligomer possesses a much larger oscillator strength. The absorption and fluorescence spectra of the compounds have been recorded in chloroform. A reasonable agreement is obtained between TDDFT vertical transition energies and the (0,0) absorption and fluorescence bands. On one hand, the pattern of the aliphatic side chains does not affect the absorption and fluorescence maxima of the compounds. On the other hand, the replacement of aliphatic chains by phenyl or thiophene rings induces hypsochromic shifts in the absorption and fluorescence spectra. Finally, the fluorescence quantum yield and lifetime of the compounds in chloroform have been obtained. From these data, the radiative and nonradiative rate constants of the deactivation of the S1 state have been determined.
Glutamatergic stimulation induces GluN2B translation by the nitric oxide-Heme-Regulated eIF2α kinase in cortical neurons (2016)

The activation of N-Methyl D-Aspartate Receptor (NMDAR) by glutamate is crucial in the nervous system function, particularly in memory and learning. NMDAR is composed by two GluN1 and two GluN2 subunits. GluN2B has been reported to participate in the prevalent NMDAR subtype at synapses, the GluN1/2A/2B. Here we studied the regulation of GluN2B expression in cortical neurons finding that glutamate up-regulates GluN2B translation through the action of nitric oxide (NO), which induces the phosphorylation of the eukaryotic translation initiation factor 2 α (eIF2α). It is a process mediated by the NO-heme-regulated eIF2α kinase (HRI), as the effect was avoided when a specific HRI inhibitor or a HRI small interfering RNA (siHRI) were used. We found that the expressed GluN2B co-localizes with PSD-95 at the postsynaptic ending, which strengthen the physiological relevance of the proposed mechanism. Moreover the receptors bearing GluN2B subunits upon NO stimulation are functional as high Ca2+ entry was measured and increases the co-localization between GluN2B and GluN1 subunits. In addition, the injection of the specific HRI inhibitor in mice produces a decrease in memory retrieval as tested by the Novel Object Recognition performance. Summarizing our data suggests that glutamatergic stimulation induces HRI activation by NO to trigger GluN2B expression and this process would be relevant to maintain postsynaptic activity in cortical neurons.

Boosting coloration efficiency in an electrochromic device using an ITO/Ag/ITO multilayered electrode and porous WO3 chromic layer (2023)

High-performance electrochromic devices (ECDs) were fabricated by introducing indium tin oxide/silver/indium tin oxide (IAI) multilayers as a transparent conducting oxide (TCO) electrode in conjunction with microstructural tailoring of tungsten trioxide (WO3) as an electrochromic (EC) layer. A 15-nm-thick Ag film with a preferential orientation of (111) and smooth morphology resulted in a high optical transmittance of 90.9% and sheet resistance 16.7 Ω/sq, making it a suitable TCO. In addition, the open network WO3 film used as an EC layer was deposited by carefully controlling the chamber pressure during the sputtering process. A high chamber pressure (2.0 Pa) resulted in a WO3 film with the lowest mass density (5.72 g/cm3) and a rough morphology. Half-cell ECDs consisting of a TCO bottom electrode (BE)/WO3 stack immersed in LiClO4 electrolyte were fabricated to verify the impact of using the IAI multi-layer stack and tailored WO3 film as a TCO and EC layer, respectively. Significant enhancement in terms of coloration efficiency was achieved for the ECDs by adopting the IAI TCO and open network WO3 EC layer compared to counterpart devices with an ITO TCO or dense WO3 EC film. This can be explained by the facile carrier extraction (injection) and transport of Li ions.
Enhanced localized surface plasmon resonance obtained in two step etched silicon nanowires decorated with silver nanoparticles (2013)

We report on localized surface plasmon resonance (LSPR) of silicon nanowires decorated with silver nanoparticles. Hydrogen peroxide in metal-assisted-etching method degenerates the surface of nanowires and creates oxygen-related defect sites. These defect sites enhance the infrared absorption at higher frequencies and emit visible light by band-to-band radiative recombination. Moreover, an almost 50-fold enhanced LSPR was obtained for 24 nm thick silver deposited 5 μm long silicon nanowires. This enhancement was attributed to the change in the dielectric constant of effective medium created by defect states. LSPR wavelength could be tuned by changing the silver particle size and nanowire length.
Parallel and nested decomposition for factoid questions (2013)

Abstract Typically, automatic Question Answering (QA) approaches use the question in its entirety in the search for potential answers. We argue that decomposing complex factoid questions into separate facts about their answers is beneficial to QA, since an answer candidate with support coming from multiple independent facts is more likely to be the correct one. We broadly categorize decomposable questions as parallel or nested , and we present a novel question decomposition framework for enhancing the ability of single-shot QA systems to answer complex factoid questions. Essential to the framework are components for decomposition recognition , question rewriting , and candidate answer synthesis and re-ranking . We discuss the interplay among these, with particular emphasis on decomposition recognition, a process which, we argue, can be sufficiently informed by lexico-syntactic features alone. We validate our approach to decomposition by implementing the framework on top of IBM Watson™, a state-of-the-art QA system, and showing a statistically significant improvement over its accuracy.
Review of Giant cell arteritis (2014)

Giant-cell arteritis (GCA) is a systemic autoimmune disease affecting primarily the elderly. Giant cell arteritis can cause sudden and potentially bilateral sequential vision loss in the elderly. Therefore, it is considered a medical emergency in ophthalmology and a significant cause of morbidity in an increasingly aging population. Ophthalmologists need to be able to recognize the classic symptoms and signs of this disease, and then be able to work-up and treat these patients in an efficient manner. An in-depth review of GCA from the literature as well as personal clinical experience follows.
Fast Max-Margin Matrix Factorization with Data Augmentation (2013)

Existing max-margin matrix factorization (M 3 F) methods either are computationally inefficient or need a model selection procedure to determine the number of latent factors. In this paper we present a probabilistic M 3 F model that admits a highly efficient Gibbs sampling algorithm through data augmentation. We further extend our approach to incorporate Bayesian nonparametrics and build accordingly a truncation-free nonparametric M 3 F model where the number of latent factors is literally unbounded and inferred from data. Empirical studies on two large real-world data sets verify the efficacy of our proposed methods. 1.
Link-coupled vibration suppression control considering product of inertia for industrial robots (2014)

To enhance the productivity and quality, high speed and high precision industrial robots are required. Industrial robots suffer a vibration caused by the axial torsion that adversely affects their motion control. In addition, the vibration of a joint is transfered to another joint because of the dynamic interferences with the robot manipulator. To overcome these problems, this paper proposes a new method for the link-coupled vibration suppression control for industrial robots, in which the product of inertia is considered. First, this paper shows a two-inertia model with a consideration that the product of inertia is a linear behavior. Hence, this paper proposes a new link-coupled vibration suppression control system, which consists of the speed controller and the state feedback. The effectiveness of proposed method is confirmed by the numerical simulation using a 3-DOF industrial robot model.

Planococcus faecalis sp. nov., a carotenoid-producing species isolated from stools of Antarctic penguins (2015)

Taxonomic studies were performed on a novel carotenoid-producing strain, designated AJ003T, isolated from faeces of Antarctic penguins. Cells of strain AJ003T were aerobic, Gram-stain-positive, cocci-shaped and orange. Strain AJ003T was capable of growing in a broad temperature range, including sub-zero growth (below − 20 to 30 °C). 16S rRNA gene sequence analysis revealed that strain AJ003T was closely related to Planococcus halocryophilus Or1T (97.4 % similarity), Planococcus antarcticus DSM 14505T (97.3 %), Planococcus kocurii NCIMB 629T (97.3 %), and Planococcus donghaensis JH1T (97.1 %). The predominant cellular fatty acids were anteiso-C15 : 0, and iso-C16 : 0.MK-7 and MK-8 were the quinones identified, and the major pigment was glycosyl-4,4′-diaponeurosporen-4′-ol-4-oic acid. The major polar lipid was phosphatidylglycerol. DNA–DNA relatedness of strain AJ003T with respect to its closest phylogenetic neighbours was 38.2 ± 0.5 % for Planococcus halocryophilus DSM 24743T, 32.2 ± 0.2 % for Planococcus antarcticus DSM 14505T, 21.0 ± 0.3 % for Planococcus kocurii DSM 20747T and 18.6 ± 1.4 % for Planococcus donghaensis KCTC 13050T. The DNA G+C content of strain AJ003T was 40.0 ± 0.6 mol%. Based on the phenotypic, chemotaxonomic and phylogenetic data, strain AJ003T is concluded to represent a novel species of the genus Planococcus, for which the name Planococcus faecalis sp. nov. is proposed. The type strain is AJ003T ( = KCTC 33580T = CECT 8759T).
Device design and flow scaling for liquid sheet jets (2018)

A design for and experimental study of microfluidic nozzles that generate thin liquid sheet jets is presented. A parametric study is conducted by varying nozzle geometry, flow rate, and fluid type, and scaling theories to scale and predict jet sheet thickness, width, and length are proposed.
Effects of interleukin-6 and leukemia inhibitory factor on the acute phase response and DNA synthesis in cultured rat hepatocytes. (1991)

Human recombinant interleukin-6 (IL-6) and human recombinant leukemia inhibitory factor (LIF) similarly stimulate synthesis of typical acute-phase proteins in the primary rat hepatocyte cultures. LIF is, however, less effective in increasing uptake of alpha-aminoisobutyric acid than IL-6. Antiserum to human IL-6 abolishes induced protein synthesis and amino acid uptake elicited by hrIL-6 but has no effect on the acute-phase response of rat liver cells stimulated by LIF. Both IL-6 and LIF inhibit basal and epidermal growth factor-induced DNA synthesis in rat hepatocytes.
An intelligent agent approach for visual information structure generation (2009)

This paper presents Cyclone, an intelligent agent based visual framework offering a means for the user to exploit, analyze and categorize unstructured information from various sources into a more structured and manageable form. The intelligent agent performs two processes, the first of which gathers the information, analyzes it and determines physical forces on visual objects which represent the information thus achieving unsupervised graph-based clustering based on lightweight metadata of the information, i.e. tags. Once an equilibrium state has been reached, the arrangement of similar information into visual fuzzy clusters and the intuitive interface of Cyclone aid the user in the process of categorization. The second process of the agent consists of monitoring the users and learning their categorization behavior in an online and nonintrusive fashion. Over time, as the derived categorization model for a particular user becomes increasingly confident, the Cyclone agent switches to an auto-categorization mode, thus automating the process of categorization for new or unassigned information and reducing the cognitive load for the user. The updated categorization model adapts the forces on the visual objects so that the visual clusters presented take into account users' behavior, combining aspects from both the unsupervised and supervised (learnt) approaches. We have conducted several multi-user experiments using real data from different application contexts in order to gain both a qualitative understanding of the user experience as well as collect quantitative data on how well the system performs, in particular, how presenting visual fuzzy clusters of the information affects a user's categorization behavior. The results illustrate that Cyclone's intelligent agent, performing clustering and categorization, coupled with an intuitive visualization interface represent an effective way of aiding users in generating a taxonomy on-the-fly and automating the process.
New Design and Manufacture of Robust DC-DC Converter Using Approximate 2DOF Digital Controller (2006)

Robust DC-DC converter which can cover extensive load changes and also input voltage changes with one controller is needed. In this paper, we propose a method for determining the parameters of 2DOF digital controller which makes the control bandwidth wider, and at the same time makes a variation of the output voltage very small at sudden changes of resistive load and the input voltage. The 2DOF digital controller whose parameters are determined by the proposed method is actually implemented on a DSP and is connected to a DC-DC converter. Experimental studies demonstrate that this type of digital controller can satisfy given specifications
Effect of glass substrates on the formation of gold-silver colloids in nanocomposite thin films (2004)

A sol-gel route to synthesize nanocomposite thin films containing phase separated metal colloids of gold (Au) and silver (Ag) was developed. Ag - Au colloids were prepared in silica films using dip coating technique. The annealing of the samples in air results in the formation of phase separated Ag and Au colloids in SiO2 thin films, showing the surface plasmon peaks at 410 nm and 528 nm. For the synthesis of phase separated Ag and Au colloids on float glass substrates, formation of the silver colloids was found strongly dependent on the surface of the float glass. On the tin rich surface formation of both gold and silver colloids took place, whereas, on the tin poor surface the formation of only gold colloids was observed. The surface dependence of the formation of silver colloids was attributed to the presence of tin as Sn2+ state on the glass surface, which oxidizes into Sn4+ during heat treatment, reducing Ag+ into silver colloids.
In-situ dynamic observation on cluster formation in amorphous oxide films (1990)

Morphologies of small metal particles and arrangements of their internal atoms became unstable under electron beam irradiation. Such structural instability cannot be explained simply by temperature effect but additional effects such as charging up effect . In the study, instability of the particle-support films of amorphous carbon and SiO 2 themselves, which were exposed inevitably to the electron beam, was noticed by observing intensity fluctuations in granular images of the films. Our preliminary work showed that fluctuation occurs with a frequency of several tens of Hertz and diminishes with a decrease in the electron beam intensity (below 10amp.). Migratory motion of atoms in small particles and the amorphous films was thought to be responsible for the image intensity fluctuation. Such an intensity fluctuation, therefore, is important for understanding small particle stability and crystallization. The present work deals with in-situ observation on amorphous oxide films using the TV recording technique. The observation was conducted on an ABT- 002B microscope at 200kV.
Omnidirectional Video Quality Metrics and Evaluation Process (2017)

Widespread of virtual reality technologies across entertainment formats has created a diverse infrastructure of related technologies as head-mount displays, dome screens and virtual reality multi-camera platforms. As omnidirectional content is processing pipeline is completely different form conventional planar video and involves multiple conversion steps which affect quality in a different way. As a result of our research we propose objective quality estimation methodology and a set of tools to evaluate different projection methods and coding tools for omnidirectional video content.
Impact of index change saturation on the growth behavior of higher-order type I ultrafast induced fiber Bragg gratings (2008)

Ultrafast infrared induced fiber Bragg gratings in a hydrogen-loaded SMF-28 fiber are shown to exhibit complex and, what we believe to be, novel spectral evolutions. It is believed that the induced grating peak profile in the fiber is nonsinusoidal as a result of the nonlinear absorption required to modify the material. Rouard's method is used to show that the observed spectral evolution is a consequence of the saturation of the nonsinusoidal index change profile.
Oxidation of glycerol using supported Pt, Pd and Au catalysts (2003)

The oxidation of aqueous solutions of glycerol is described and discussed for Pd, Pt and Au nanoparticles supported on graphite and activated carbon. The oxidation in a batch reactor at 60 °C and 1 bar pressure using air as oxidant was initially investigated. Under these conditions, supported Pd and Pt catalysts give some selectivity to glyceric acid, but the main reaction products are considered to be non-desired C1 by-products, e.g. CO2, HCHO and HCOOH. In addition, under these conditions, supported Au catalysts were totally inactive. Using an autoclave with pure oxygen at 3 bar pressure gave a significant improvement in reactivity and, for Pt and Au catalysts, the formation of C1 by-products was eliminated when NaOH was added. In particular, it was noted that, in the absence of NaOH, the Au/C catalyst was inactive. For 1 wt.% Au/graphite or activated carbon, 100% selectivity to glyceric acid at high conversion was readily achieved. The role of the base is discussed and it is proposed that the base aids the initial dehydrogenation via H-abstraction of one of the primary OH groups of glycerol and, in this way, the rate limiting step in the oxidation process is overcome.
