Enhancement on CO<sub>2</sub> Bubble Absorption in MDEA Solution by TiO<sub>2</sub> Nanoparticles (2013)

TiO 2 -N-methyldiethanolamine(MDEA)-H 2 O nanofluids were prepared by dispersing TiO 2 nanoparticles in the 50wt% (mass fraction) MDEA solution. The stability of nanofluids was studied by the method of absorbance. Only with mechanical agitation, the nanofluids can keep stable at least 48 h without any dispersant. The surface tensions; kinematic viscosities and thermal conductivities of the MDEA solution were measured at the temperature of 20 °C when the TiO 2 na-noparticles concentration was 0.05wt%, 0.2wt%, 0.4wt% and 0.8wt%. The results show that they all increase with increasing concentration of the nanoparticles. The maximum enhancement of the surface tension, kinematic viscosity and thermal conductivity is 0.6 %, 4.6 % and 5.9 % respectively at the concentration of 0.8 wt%. The influence of nanoparticles on CO2 bubble absorption in the MDEA solution was studied. It can be found that the CO 2 absorption rate can be enhanced by 1.95%, 6.53%, 7.79%, 11.54% when the TiO 2 nanoparticles concentration is 0.05wt%, 0.2wt%, 0.4wt% and 0.8wt% respectively. The possible mechanisms for the phenomena in experiments and related results are also explained.
Meeting browsers and meeting assistants (2012)

The previous chapter (Chapter 11) explained how user requirements directed our development of meeting support technology, more specifically meeting browsers and assistants. Chapters 3 to 9 discussed the enabling components, i.e. the multimodal signal processing necessary to build meeting support technology. In the following, we will present an overview of the meeting browsers and assistants developed both in AMI and related projects, as well as outside this consortium.
Research and Development Commitments in an Integrated Plasma Collection and Plasma Fractionation Environment (1998)

Plasma fractionation has emerged as one of the most scientifically demanding fields in the biopharmaceutical area. Producing safe plasma derivatives implies the development, use, and proper understanding of sensitive testing technologies to detect infection markers in starting plasma. It also requires the implementation of carefully selected, nondenaturing, efficient plasma protein purification and viral reduction technologies that do not alter the physiological functions and clinical potential of plasma proteins. Success in this field can be achieved only by a strong commitment to sustain constant research and development of projects targeting the production of safer and innovative plasma products.
Experimental results with a scanning stepper for synchrotron-based x-ray lithography (1988)

A second generation of synchrotron-compatible x-ray steppers is described which uses the scanning exposure method to minimize overhead time between alignment and exposure. Available x-ray intensity is increased, since a thin exposure window, only a few mm high, can be used to separate the beam line vacuum from the exposure tool which operates in ambient air. First results indicate sufficient mechanical stability to allow the mask/wafer unit to be scanned in an aligned position.
Matrix Metalloproteinase Inhibition Prevents Oxidative Stress-Associated Blood–Brain Barrier Disruption after Transient Focal Cerebral Ischemia (2001)

Oxidative stress generated during stroke is a critical event leading to blood-brain barrier (BBB) disruption with secondary vasogenic edema and hemorrhagic transformation of infarcted brain tissue, restricting the benefit of thrombolytic reperfusion. In this study, the authors demonstrate that ischemia-reperfusion-induced BBB disruption in mice deficient in copper/zinc-superoxide dismutase (SOD1) was reduced by 88% ( P < 0.0001) and 73% ( P < 0.01), respectively, after 3 and 7 hours of reperfusion occurring after 1 hour of ischemia by the inhibition of matrix metalloproteinases. Accordingly, the authors show that local metalloproteinase-generated proteolytic imbalance is more intense in ischemic regions of SOD1 mice than in wild-type litter mates. Moreover, active in situ proteolysis is, for the first time, demonstrated in ischemic leaking capillaries that produce reactive oxygen species. By showing that oxidative stress mediates BBB disruption through metalloproteinase activation in experimental ischemic stroke, this study provides a new target for future therapeutic strategies to prevent BBB disruption and potentially reperfusion-triggered intracerebral hemorrhage.
UFA: Ultra Flat Architecture for high bitrate services in mobile networks (2008)

The challenge in the coming years for mobile networks will be to offer high bit rate data services to customers in mobility. Future mobile architectures are being standardized to offer mobility between heterogeneous access technologies. The design of these architectures does not take into account scalability requirement since they are centralized with many network levels and dependency. This paper proposes a new architecture, called ultra flat architecture (UFA), that integrates scalability requirement. The key idea of UFA is the reduction of the number of network nodes to one node which is the base station, by the distribution of traditional user and control plane functions in this node. We detail UFA architecture and show how it optimizes service establishment and mobility procedures. We perform a first performance evaluation of the solution performance and expose the first requirements that guarantee seamless handover for real-time services.
Removal of Poly Aromatic Hydrocarbons (PAHs) from Water: Effect of Nano and Modified Nano-clays as a Flocculation Aid and Adsorbent in Coagulation-flocculation Process (2014)

Water treatment process involving simultaneous action of adsorption on different nano and organo-modified nano-clays followed by coagulation-flocculation by alum and poly aluminium chloride (PAC) has been evaluated for the removal of PAHs (naphthalene, acenaphthalene, phenanthrene, fluoranthene, anthracene, and pyrene) from water. When clay minerals along with alum and PAC were used for treatment, 37.4–100.0% removal of PAHs was observed compared to 20–38% removal using normal water treatment process with either alum or alum + PAC. The effectiveness of clay minerals for removal of PAHs followed the order (P < 0.05): halloysitenano-clay (HN-clay) < normal bentonite (NB-clay) < hydrophilic nano-bentonite (HNB-clay) < nano-montmorillonite modified with dimethyl dialkyl amine (DMDA-M-clay) ≈ nano-montmorillonite modified with octadecylamine and aminopropyltriethoxysilane (ODAAPS-M-clay) ≈ nano-montmorillonite modified with octadecylamine (ODA-M-clay) in combination with alum + PAC. The modified treatment process (alum + PAC + clay minerals), where water was initially treated with clays followed by normal process of coagulation (alum + PAC), was found to be the most effective method with maximum removal for ODAAPS-M-clay (97.7–100.0%) which is at par wih ODA-M (97.0–100.0%), and DMDA-M-clay (94.8–100%). The removal of PAHs varied in the order: naphthalene ≈ acenaphthalene > anthracene ≈ pyrene > phenanthrene > fluoranthrene. The treatment combination having the maximum removal capacity was also used eficiently for the removal of PAHs from natural and fortified natural water. This article demonstrated adsorption-coagulation integrated system has the potential to remediate PAHs polluted water.
Four-valued threshold logic full adder circuit implementations (1978)

A four-valued logic full adder accepts two four-valued inputs and a binary carry input and produces a two-quaternary-digit, base-four, output word that is the sum of the values of the inputs. In this paper we present two new current-mode logic realizations of the four-valued logic full adder. Also reviewed is a recent I2L realization of this function. In some applications, the use of these four-valued logic full adders requires fewer than 50% of the devices necessary to implement the same function with binary full adders.
Bovine Pericardium for Dural Grafts: Clinical Results in 35 Patients (1997)

To the Editor: In our article (1), Tutoplast was mistakenly identified as the manufacturer for lyophilized cadaveric human dura mater. Lyophilized dura is actually manufactured by B. Braun (Melsungen, Germany) and has recently been recalled worldwide. Tutoplast is not lyophilized dura but is processed using osmatic treatment, as correctly pointed out in one of the comments. It is manufactured by BioDynamics International (Tampa, FL) and has not been associated with infection transmission, according to the manufacturer. We apologize for any confusion that may have resulted from this error. John A. Anson Albuquerque, New Mexico
Clinical Impact of Suicide Gene Therapy in Allogeneic Hematopoietic Stem Cell Transplantation (2010)

Allogeneic hematopoietic stem cell transplantation (allo-SCT) from an HLA-matched related or unrelated donor is a curative option for patients with high-risk hematological diseases. In the absence of a matched donor, patients have been offered investigational transplantation strategies such as umbilical cord blood SCT or family haploidentical SCT. Besides the activity of the conditioning regimen, most of the antileukemic potential of allo-SCT relies on alloreactivity, promoted by donor lymphocytes reacting against patient-specific antigens, such as minor and major histocompatibility antigens, ultimately translating into cancer immunotherapy. Unfortunately, alloreactivity is also responsible for the most serious and frequent complication of allo-SCT: graft-versus-host-disease (GvHD). The risk of GvHD increases with the level of HLA disparity between host and donor, and leads to impaired quality of life and reduced survival expectancy, particularly among patients receiving transplants from HLA-mismatched donors. Gene transfer technologies are promising tools to manipulate donor T cell immunity to enforce the graft-versus-tumor effect, to promote functional immune reconstitution (graft vs. infection), and to prevent or control GvHD. To this purpose, several cell and gene transfer approaches have been investigated at the preclinical level, and are being implemented in clinical trials. Suicide gene therapy is to date the most extensive clinical application of T cell-based gene therapy. In several phase I-II clinical studies conducted worldwide this approach proved highly feasible, safe, and effective in promoting a dynamic and patient-specific modulation of alloreactivity. This review focuses on this approach.
Characterization of Air Flow Management and Control in a Fuel Cell Turbine Hybrid Power System Using Hardware Simulation (2005)

Air flow management and control in a fuel cell gas turbine hybrid power system is evaluated using the Hybrid Performance (Hyper) hardware simulation facility at the National Energy Technology Laboratory (NETL), U.S. Department of Energy. The Hyper facility at NETL is a hardware simulation of a fuel cell gas turbine hybrid power system capable of emulating systems in the range of 300kW to 900kW. The hardware portion is comprised of a modified single-shaft gas turbine, a high performance exhaust gas recuperator, several pressure vessels that represent the volumes and flow impedances of the fuel cell and combustors, and the associated integration piping. The simulation portion consists of a real time fuel cell model that is used to control a natural gas burner which replicates the thermal output of a solid oxide fuel cell. Thermal management in the fuel cell component of the hybrid system, especially during an imposed load transient, is improved through the control of cathode air flow. This can be accomplished in a fuel cell turbine hybrid by diverting air around the fuel cell system. Two methods for air flow control are presented in the paper. In this paper, the use of bleed air by-pass and cold air by-pass are characterized quantitatively in terms of compressor inlet flow, process limits, system efficiency and system performance.

Solution Luminescence of Anthraquinone, Naphthoquinone, and Some Derivatives at Room Temperature (1971)

9, 10-Anthraquiuone (AQ) in an inert aliphatic solvent emits luminescence at room temperature. The emission consists of (1) solution phosphorescence and (2) delayed thermal fluorescence (DTF). We found that similar emission is observed for some AQ and naphthoquinone (NQ) derivatives. The singlet–triplet separation, Δ E 1,3 , was determined from the DTF–phosphorescence separation.
The contribution of monocyte infection and trafficking to viral persistence, and maintenance of the viral reservoir in HIV infection (2003)

Abstract Cellular viral reservoirs and anatomic sanctuary sites allow continuing HIV-1 replication in patients with suppressed plasma viremia who are receiving highly active antiretroviral therapy and prevent eradication of HIV-1 by these regimens. Cells of macrophage lineage, including monocytes subsets within the blood, play a role in HIV-1 persistence. Evidence of sequence evolution in blood monocytes, in comparison to resting CD4+ T cells, demonstrates their distinct contribution to plasma viremia. There is evidence to suggest that a specific monocyte subset, of CD14loCD16hi phenotype, is more susceptible to HIV-1 infection than the majority of blood monocytes. Trafficking of monocytes through various tissues following their emigration from the bloodstream allows these cells to differentiate into tissue macrophages, or potentially to egress from the tissues as migratory dendritic cells. This review provides an evaluation of the contribution of monocytes to HIV-1 persistence and the HIV-1 reservoir, essential for the effective design of therapeutic eradication strategies.
Dielectric Constant and Optical Reflectance of Ceramic Filler‐Added BaO–ZnO–B <sub>2</sub> O <sub>3</sub> –P <sub>2</sub> O <sub>5</sub> Glass Composites (2008)

This study examined the influence of the addition of ceramic fillers (up to 20 wt% of TiO 2 , Al 2 O 3 , and ZnO, respectively) to a BaO–ZnO–B 2 O 3 –P 2 O 5 glass matrix on the dielectric and optical properties with the aim of using this material as the barrier ribs in plasma display panels. The modification of the dielectric constant by the fillers was related to the formation of secondary phases, the changes in the glass composition by the partial dissolution of the fillers, and the presence of pores. The reflectance of the composites ranged from 60% to 80% with the addition of 20 wt% filler.
Cognitive Radio Transmission Based on Direct Sequence MC-CDMA (2008)

In this paper, we propose a cognitive cellular system based on DS MC-CDMA to coexist with a number of narrow-band legacy systems in the same frequency range. If the bandwidth and the frequency location of each narrow-band system are known to this cognitive MC-CDMA, it is possible to mitigate their interfering effect in the cognitive receivers by adaptive transmission. We will develop an algorithm for calculating the adaptive transmission parameters and show that it combats interference in the channel effectively.
A combination of algebraic multigrid method and adaptive mesh refinement for large-scale electromagnetic field calculation (2010)

A combination of algebraic multigrid method (AMG) and adaptive mesh refinement is presented in this paper to solve large-scale electromagnetic field problems. The oscillatory smooth error (the error not eliminated by the smoother) by the classical AMG method could be efficiently reduced by replacing the virtual coarse and fine grid of classical AMG method with the real coarse and refined mesh of adaptive mesh refinement and accordingly, the prolongation mapping the coarse to fine grid and restriction mapping the fine to coarse grid are established basing on the relationship between the coarse mesh and refined mesh.
Potential inhibitors of S-adenosylmethionine-dependent methyltransferases. 4. Further modifications of the amino acid and base portions of S-adenosyl-L-homocysteine (1976)

Structural analogues of S-adenosyl-L-homocysteine (L-SAH), with modifications in the amino acid or base portions of the molecule, have been synthesized and evaluated for their abilities to inhibit the transmethylations catalyzed by catechol O-methyltransferase (COMT), phenylethanolamine N-methyltransferase (PNMT), histamine N-methyltransferase (HMT), hydroxyindole O-methyltransferase (HIOMT), and indoleethylamine N-methyltransferase (INMT). From these studies some interesting and potentially useful differences in the structural features of L-SAH needed to produce maximal binding to these methyltransferases were detected. This paper provides evidence that 8-azaadenosyl-L-homocysteine is a potent and selective inhibitor of HIOMT, whereas N6-methyladenosyl-L-homocysteine and N6-methyl-3-deazaadenosyl-L-homocysteine are selective inhibitors in INMT. In contrast, it was found that S-tubercidinyl-L-homocysteine was a fairly potent, but nonselective inhibitor of all of the methyltransferases studied. The differences and the similarities in the requirements for the binding of SAH to methyltransferases which were detected in this study and earlier studies from our laboratory, are described. The possibilites of utilizing differences in binding requirements for the design of SAH analogues as specific inhibitors of methyltransferases are discussed.
Gaze as a Window to the Process of Novel Adjective Mapping (2019)

This study evaluated two explanations for how learning of novel adjectives is facilitated when all the objects are from the same category (e.g., exemplar and testing objects are all CUPS) and the object category is a known to the children. One explanation (the category knowledge account) focuses on early knowledge of syntax–meaning correspondence, and another (the attentional account) focuses on the role of repeated perceptual properties. The first account presumes implicit understanding that all the objects belong to the same category, and the second account presumes only that redundant perceptual experiences minimize distraction from irrelevant features and thus guide children’s attention directly to the correct item. The present study tests the two accounts by documenting moment-to-moment attention allocation (e.g., looking at experimenter’s face, exemplar object, target object) during a novel adjective learning task with 50 3-year-olds. The results suggest that children’s attention was guided directly to the correct item during the adjective mapping and that such direct attention allocation to the correct item predicted children’s adjective mapping performance. Results are discussed in relation to their implication for children’s active looking as the determinant of process for mapping new words to their meanings.
Interactive tools to support animation tasks (1987)

Interactive tools have long been important fundamental components of computer animation systems. Interactive tools in the form of electronic paint systems, cel painting systems, and in-betweening systems are major components of two-dimensional character animation systems. Major interactive components of three-dimensional animation systems include motion design and motion previewing systems as well as geometric modeling systems.
Cellular Markers of Inflammation in the Airways of Allergic Sheep with and without Allergen-induced Late Responses (1988)

Allergic sheep respond to inhaled Ascaris suum antigen either with an acute bronchoconstriction alone (acute responders, AR) or both an acute and late bronchoconstriction (dual responders, DR). In this study, we determined if: (1) inflammatory cell composition of bronchoalveolar lavage (BAL) obtained during the late response differs between DR and AR; (2) the difference in inflammatory cells is dependent on the prechallenge BAL cell composition; and (3) drugs that block late airway responses also modify this airway inflammation. Antigen challenge caused significant immediate mean increases in specific lung resistance (SRL) both in DR (n = 28) and in AR (n = 14), but only DR had a late increase in SRL. There were no differences between the two groups in total cell returns or in the percentage of neutrophils in BAL 7.5 to 8 h after challenge, but DR had a 3.5-fold increase (p less than 0.05) in the percentage of eosinophils. Methylprednisolone succinate (15 mg/kg intravenously) given to DR (n = 7) 3 h after antigen challenge blocked the late airway response and the eosinophil response. When BAL was performed both before and after (i.e., 7.5 to 8 h) antigen challenge, similar results were observed: AR (n = 7) and DR (n = 14) exhibited characteristic airway responses. No significant differences in prechallenge BAL cell composition were observed between AR and DR; after challenge both groups showed increases in neutrophils, but only the DR showed an increase (p less than 0.05) in eosinophils. Pretreatment of DR with the antiallergic agents (cromolyn sodium or nedocromil sodium aerosol, 20 mg) blocked the immediate and late responses and the late increase in BAL eosinophils.(ABSTRACT TRUNCATED AT 250 WORDS)
