Preparation of Bioactive Cellulose/Hydroxyapatite Composite Tapes (2006)

A composite material consisting of cellulose and HAp was prepared using coagulation of a native cellulose suspension. Composite tapes with a HAp content below 50 vol.% exhibit a gradient of filler particles across the cross-section of the sample due to gravity force that causes sedimentation of HAp, as long as the viscosity of the suspension is below a critical level during the coagulation process. According to gravimetric and solution analysis as well as SEM, the filler content influences the amount and uniformity of HCA precipitated in the surface of the tape. With increasing content of filler in the cellulose matrix, the apatite growth from SBF is promoted, due to a higher amount of HAp particles that serve as nucleation sites.
The Separation of the Rotational Coordinates from the N-Particle Schroedinger Equation (1950)

By group theoretical arguments, it can be shown that a wave function, ψμL, for a system of N particles corresponding to a total angular momentum quantum number, L, and a quantum number, μ, referring to the z component of angular momentum may be written as a sum of terms: ψμL=Σs DL(R)μs*χsL.The DL(R)μs are the representation coefficients for the Lth irreducible representation of the three-dimensional rotation group, and are functions of the three coordinates specifying the orientation of the system of particles in space. The χμL are functions of the 3N−6 coordinates specifying the relative configuration of the N-particle system. The set of coupled differential equations for the functions, χμL, is obtained explicitly. The special case of the three-particle system is discussed in detail. The present treatment is more directly usable than the previous discussions since the basic equations do not involve implicit relationships between the variables.
Kinetics and Thermochemistry of the Hydroxycyclohexadienyl Radical Reaction with O2:  C6H6OH + O2 ⇌ C6H6(OH)OO (2004)

The UV absorption spectrum along with the self-reaction and oxidation reaction kinetics of the hydroxycyclohexadienyl radical, C6H6OH (which results from OH addition to benzene), were studied using excimer laser photolysis coupled to transient UV absorption. The radicals were generated by photolysis of N2O/H2O/C6H6/He mixtures at 193 nm in a series of chemical reactions initiated by O(1D). The radical has continuous absorption in the range 260−340 nm with a maximum absorption cross-section of (8.1 ± 1.4) × 10-18 cm2 molecule-1 at 280 nm. Reaction of the radical with molecular oxygen, C6H6OH + O2 ⇌ C6H6(OH)OO (1), and self-reaction C6H6OH + C6H6OH → products (2), were studied over the 252−285 K temperature range at 1.01 ± 0.02 bar (He). The radical temporal profiles were recorded via transient absorption at 315 nm. In reaction 1, two-time-domain “equilibration” kinetics were recorded in the temperature range 252−273 K. The rate constant of the addition reaction is k1 = (1.4 ± 0.8) × 10-12 exp(−18.6 ± 1.7 kJ mol-1/RT) cm3 molecule-1 s-1. The standard enthalpy of reaction 1 was determined from the measured equilibrium constants using the third law method: = −43.6 ± 2.0 kJ mol-1. The measured rate constant of self-reaction 2 is k2 = (6 ± 3) × 10-11 exp(−2.00 ± 1.6 kJ mol-1/RT) cm3 molecule-1 s-1.
Characterization of Interleukin-15-Transpresenting Dendritic Cells for Clinical Use (2017)

Personalized dendritic cell- (DC-) based vaccination has proven to be safe and effective as second-line therapy against various cancer types. In terms of overall survival, there is still room for improvement of DC-based therapies, including the development of more immunostimulatory DC vaccines. In this context, we redesigned our currently clinically used DC vaccine generation protocol to enable transpresentation of interleukin- (IL-) 15 to IL-15R<i>βγ</i>-expressing cells aiming at boosting the antitumor immune response. In this study, we demonstrate that upon electroporation with both <i>IL-15</i> and <i>IL-15Rα</i>-encoding messenger RNA, mature DC become highly positive for surface IL-15, without influencing the expression of prototypic mature DC markers and with preservation of their cytokine-producing capacity and their migratory profile. Functionally, we show that IL-15-transpresenting DC are equal if not better inducers of T-cell proliferation and are superior in tumor antigen-specific T-cell activation compared with DC without IL-15 conditioning. In view of the clinical use of DC vaccines, we evidence with a time- and cost-effective manner that clinical grade DC can be safely engineered to transpresent IL-15, hereby gaining the ability to transfer the immune-stimulating IL-15 signal towards antitumor immune effector cells.
Robust Reachable Set (2019)

Reachable set computation is one of the primary techniques for safety verification of linear dynamical systems. In reality the underlying dynamics have uncertainties like parameter variations or modeling uncertainties. Therefore, the reachable set computation must consider the uncertainties in the dynamics to be useful i.e . the computed reachable set should be over or under approximation if not exact. This paper presents a technique to compute reachable set of linear dynamical systems with uncertainties. First, we introduce a construct called support of a matrix. Using this construct, we present a set of sufficient conditions for which reachable set for uncertain linear system can be computed efficiently; and safety verification can be performed using bi-linear programming. Finally, given a linear dynamical system, we compute robust reachable set, which accounts for all possible uncertainties that can be handled by the sufficient conditions presented. Experimental evaluation on benchmarks reveal that our algorithm is computationally very efficient.

A new monoclinic unit cell was observed with a = 5.836, b = 6.226, c = 17.342 A, and y = 91.34”. The impurity phase coexisting with Ba2Tl,05 was determined to be Ba4T1,0n, having an orthorhombic unit cell with a = 5.748, b = 7.221, and c = 9.361 Ai. The possible mechanism of solid-solid reaction of Ba, Tl oxides is discussed. Q 1990 Academic PESS, IX.
ENZYME LINKED IMMUNOSORBENT ASSAY (ELISA) FOR DETECTION OF CLOSTRIDIUM BOTULINUM TYPE B TOXIN (1979)

The enzyme-linked immunosorbent assay using different techniques has been applied to determine botulinum type B toxin. With the so-called "sandwich" technique, about 5,000 mouse ip LD50 of type B toxin can be detected. With the "double-sandwich" technique, about 400 mouse ip LD50 of toxin is detected and different commerical antisera are useful. For accurate quantification of botulinum toxins in culture filtrates, addition of EDTA to samples seems to be necessary. Cross-reactivity of the assay depends on the specificity of the antisera against botulinum type B toxin used and is almost eliminated with antiserum prepared against the toxic component of type B toxin.

Diketopyrrolopyrrole-based Small Molecule for Application in Solution Processed Organic Solar Cells (2014)

A novel donor-π bridge - acceptor (A)-π bridge - donor type molecule (PCTDPP20) with planar core based on diketopyrrolopyrrole (DPP) and carbazole is synthesized by the Suzuki coupling reaction. We introduce phenyl rings to extend the π-conjugation length as a π-bridge. The HOMO and LUMO energy levels of PCTDPP20 are −5.13 and −3.57 eV, respectively. From the UV-Vis spectra, we confirm that the maximum absorption wavelgth (λmax) of the PCTDPP20 annealed film at 100°C is red-shifted about 30 nm and the absorption intensity at 600 ∼ 650 nm increase compared to that of as-spun film. And the OFET based on PCTDPP20 annealed at 100°C exhibits a highest hole mobility of 1.6 × 10−4 cm2/Vs together with a Ion/Ioff ratio of 1.0 × 104 and a Vth of 14 V. Also, the photovoltaic properties are investigated in the device structure of ITO/PEDOT:PSS/PCTDPP20:PC60BM (with different blend ratios)/Al. Among the OSCs, PCTDPP20:PCBM weight ratio of 1:0.8 and termal annealing process at 100°C for 10 min are optimum belnd ratio and temperature, respectively. This device shows the best performance with a highest PCE of 0.95% a Jsc of −2.69 mA/cm2, a Voc of 0.79 V and a fill factor of 44.5%.
Electrooptic temperature sensor based on a Fabry-Pe/spl acute/rot resonator with a liquid crystal film (2006)

An electrooptic (EO) temperature sensor based on a Fabry-Pe/spl acute/rot (FP) resonator with a nematic liquid crystal (NLC) film is proposed. A novel compensation scheme of the EO effect allows for precise determination of temperature by monitoring the resonant wavelength of the NLC FP sensor. The proposed EO temperature sensor provides good stability, high resolution, self-calibration capability, and low driving voltage.
Measurements of neutral and ion composition, neutral temperature, and electron energy distribution function in a CF4 inductively coupled plasma (2001)

In this article, we present comprehensive measurements of the neutral number densities, ion number densities, and the electron energy distribution function in a CF4 inductively coupled plasma at pressures between 1 and 30 mTorr, and deposited powers between 150 and 550 W. High degrees of dissociation are observed at the lower pressures. We believe this is a result of the large electron temperature at the lower pressures. The measurements of all the dominant radical and stable neutral species using appearance potential mass spectrometry allows the estimation of the neutral temperature at the neutral sampling aperture. The neutral temperature is also estimated from the change in the number density of a trace amount of argon added to CF4 when the plasma is turned on. Neutral temperatures up to 930 K are measured at the sampling aperture. The increase in neutral temperature with power at a constant pressure results in a decrease in the total neutral number density at a constant pressure. The electron temperature is sensitive to the neutral number density, especially at low densities. This leads to a significant increase in the electron temperature with power, resulting in the higher degrees of dissociation observed at low pressures. The number densities of radicals and their corresponding ions are generally strongly correlated in the plasma. We show indirect evidence for large surface loss coefficients for C and CF radicals.

Studies on Enteric Anthelmintics: Impact of Single Point Structural Change on the Activity Profile (1988)

The impact of change only in one heteroatom in the substituent at position 5(6) of methyl benzimidazole-2-carbamates on the profile of anthelmintic activity against intestinal worms Ancylostoma ceylanicum (hookworm), Nippostrongylus brasiliensis (trichostrongylid), Syphacia obvelata (oxyurid) and Hymenolepis nana (cestode) has been studied. The observations made are likely to evoke interest for understanding the SAR in methyl benzimidazole-2-carbamates anthelmintics at a molecular level
Metal Ion Quenching Kinetics of DTDCI in Viscous Solution and Nafion Membranes: Model System for Near Infrared Fluorescence Sensing (1998)

Fo¨rster type energy transfer offers opportunities as a sensitive and frequently selective method of monitoring the concentration of analytes in medical sensing applications. However, the fluorescence quenching kinetics observed in microheterogeneous media such as tissue are likely to be less than ideal. In the present article, the quenching kinetics of the carbocyanine dye DTDCI by transition metal ions in solutions and in the microheterogeneous polymer Nafion (a registered trademark of Dupont Corporation) are reported and compared with a view to understanding the complex fluorescence kinetics likely to be encountered in biological media. © 1998 Society of Photo-Optical Instrumentation Engineers.

Integrated Hull Design, Boundary-Layer Control, and Propulsion of Submerged Bodies (1967)

Power requirements of large submerged bodies at high Reynolds numbers are optimized by the hydrodynamic synthesis of body design, boundary-layer control, and propulsion. Conventional rigid skin, all turbulent boundary layers, and a single suction slot are accepted as realistic engineering constraints. A 3:1 body has been designed and has been tested in a wind tunnel at a Reynolds number of 10; the wake drag has been found to be CDW = 0.002, and the equivalent suction drag CDS = 0.0142 yielding a total equivalent drag CD = 0.0162 (based on volume). This can be compared to CD = 0.0235 for the best conventional streamlined body (Akron airship model). A total engine power coefficient has also been determined, Cp* = 0.01585, while a conventional streamlined vehicle with stern wake propeller has a Cp* = 0.0215, thereby showing a net gain of 26%. There is a possible tradeoff between suction and propulsion powers allowing the total power coefficient to decrease to CP* = 0.0100 and to reach a 50% power gain.
Covalent Surface Chemistry of Single‐Walled Carbon Nanotubes (2005)

Abstract In this review article, we explore covalent chemical strategies for the functionalization of carbon‐nanotube surfaces. In recent years, nanotubes have been treated as chemical reagents (be it inorganic or organic) in their own right. Indeed, from their inherent structure, one can view nanotubes as sterically bulky, π‐conjugated ligands, or conversely as electron‐deficient alkenes. Hence, herein we seek to understand, from a structural perspective, the breadth and types of reactions single‐walled nanotubes (SWNTs) can undergo in solution phase, not only at the ends and defect sites but also along the sidewalls. Controllable chemical functionalization suggests that the unique electronic and mechanical properties of SWNTs can be tailored in a determinable manner. Moreover, prevailing themes in nanotube functionalization have been involved with dissolution of tubes.

Immobilization of Lipase to Chitosan Beads using a Natural Cross‐Linker (2007)

Genipin, a reagent of plant origin was used for the immobilization of lipase by cross-linking to chitosan beads. The catalytic properties and operational and storage stabilities of the immobilized lipase were compared with the soluble lipase. Under optimum conditions, 198 microg protein was bound per g chitosan with a protein-coupling yield of 35%. The hydrolytic activity was 10.8 U/g chitosan and the relative specific activity was 108%. The immobilized lipase showed better thermal and pH stabilities compared to the soluble form. The immobilized enzyme exhibited mass transfer limitations as reflected by a higher apparent K(m) value and a lower energy of activation. The immobilized enzyme retained about 74% of its initial activity after five hydrolytic cycles.

The basal component of the nematode dense-body is vinculin (1989)

We have constructed a genomic DNA expression library and screened it with antibodies in order to clone the deb-1 gene from the nematode Caenorhabditis elegans. This gene encodes a protein found at the base of the muscle dense-bodies, structures which attach actin thin filaments to the sarcolemma. We report the complete sequence of the deb-1 gene, its localization on the C. elegans genetic map, and the finding that it encodes a protein with a sequence very similar to chicken vinculin. We also show that the difference in size between this nematode protein and chicken vinculin is due in part to the absence from the nematode sequence of one of the three internal repeats found in the chicken sequence.
Anti-NMDA Receptor Encephalitis Which Has Shown Clinical Symptoms of Schizophrenia (2013)

Encephalitis associated with antibodies to the N-methyl-D-aspar tate (NMDA) receptor has variable clinical manifestations and treatment responses. Anti-NMDAR encephalitis is often associated with ovarian teratoma, but some cases without tumor have been reported. Here, we describe a patient who has shown psychiatric symptoms, memory impairment and been diagnosed as schizophrenia for one year and had anti-NMDA receptor antibody. The patient showed atypical clinical course compared to previous cases with anti-NMDA receptor encephalitis. J Korean Neurol Assoc 31(2):115-117, 2013
The tyrosine kinases Syk and Lyn exert opposing effects on the activation of protein kinase Akt/PKB in B lymphocytes (1999)

The protein kinase Akt/PKB is a crucial regulator of cell survival in response to mitogenic signals. The increased kinase activity of v-akt, an oncogenic form of Akt/PKB, causes mouse T cell lymphoma, and overexpression of Akt/PKB is associated with progression of several tumor types in human. In this study, we demonstrate that ligation of B cell antigen receptor (BCR) leads to activation of Akt/PKB in B lymphocytes. BCR-induced activation of Akt/PKB required the tyrosine kinase Syk, which was not previously known to regulate Akt/PKB. In contrast, BCR crosslinking of Lyn-deficient B cells resulted in markedly enhanced hyperphosphorylation and activation of Akt/PKB compared with wild-type B cells, indicating that this Src-family kinase acts as an endogenous antagonist of BCR-induced Akt/PKB activation. Lyn inhibited Akt/PKB additively with an okadaic acid-sensitive endogenous phosphatase(s). Expression of exogenous Lyn in mutant cells restored normal BCR-induced phosphorylation of Akt/PKB. Negative regulation of Akt/PKB by Lyn was not dependent on the protein phosphatases SHP-1, SHP-2, or SHIP. Our results show that Lyn provides a mechanism for negative regulation and opposes the effect of Syk on BCR-mediated activation of Akt/PKB. Deregulation of Akt/PKB correlates with the hyperresponsiveness of B cells from Lyn-deficient mice stimulated by BCR crosslinking and may contribute to the autoimmune syndrome that develops in Lyn-deficient animals.
A Strong Tracking Square Root Central Difference FastSLAM for Unmanned Intelligent Vehicle With Adaptive Partial Systematic Resampling (2016)

An improved fast simultaneous localization and mapping (FastSLAM) algorithm based on the strong tracking square root central difference Kalman filter (STSRCDKF) with adaptive partial systematic resampling is proposed in this paper to solve the large-scale simultaneous localization and mapping (SLAM) problem for unmanned intelligent vehicle. In the proposed algorithm, STSRCDKF is composed of a strong tracking filter and a square root central difference Kalman filter. STSRCDKF is used to design an adaptive adjusting proposal distribution of the particle filter and to estimate the Gaussian densities of the landmarks. Moreover, an adaptive partial systematic resampling operation is carried out to reduce the degree of particle degeneracy and maintain the diversity of particles. The performance of the proposed algorithm is compared with that of central difference FastSLAM and FastSLAM2.0; the simulation results based on the simulator and two benchmark data sets verify that the proposed algorithm has better adaptability and robustness to respond with time-varying measurement noise. In addition, it reduces computational cost and improves state estimation accuracy and consistency. Furthermore, the validity of the proposed algorithm is verified by the experimental result in campus test site of Beijing University of Technology.
Synthesis of polypropylene wrapped carbon nanotubes composite via in situ graft method with maleic anhydride (2007)

Wrapped carbon nanotubes with polypropylene were synthesised by in situ graft method and used as a reinforcement agent for commercial polypropylene. Scanning electron microscopy and transmission electron microscopy revealed that carbon nanotubes were wrapped by polypropylene and dispersed homogeneously in polypropylene matrix. Infrared spectroscopy results showed that there was covalently linkage between polypropylene and carbon nanotubes via maleic anhydride grafting. The linkage was further confirmed by Raman observation. Furthermore, the X-ray diffraction research revealed that the carbon nanotubes act as nucleating agent to promote crystallisation. Owing to the uniform dispersion of carbon nanotubes and covalent adhesion between polypropylene and carbon nanotubes, the thermal stability of polypropylene was improved.
