Ambient Carbon Dioxide Capture by Boron-Rich Boron Nitride Nanotube (2011)

Carbon dioxides (CO(2)) emitted from large-scale coal-fired power stations or industrial manufacturing plants have to be properly captured to minimize environmental side effects. From results of ab initio calculations using plane waves [PAW-PBE] and localized atomic orbitals [ONIOM(wB97X-D/6-31G*:AM1)], we report strong CO(2) adsorption on boron antisite (B(N)) in boron-rich boron nitride nanotube (BNNT). We have identified two adsorption states: (1) A linear CO(2) molecule is physically adsorbed on the B(N), showing electron donation from the CO(2) lone-pair states to the B(N) double-acceptor state, and (2) the physisorbed CO(2) undergoes a carboxylate-like structural distortion and C═O π-bond breaking due to electron back-donation from B(N) to CO(2). The CO(2) chemisorption energy on B(N) is almost independent of tube diameter and, more importantly, higher than the standard free energy of gaseous CO(2) at room temperature. This implies that boron-rich BNNT could capture CO(2) effectively at ambient conditions.
DragonNet: A robust mobile Internet service system for long distance trains (2011)

Wide range wireless networks often suffer from annoying service deterioration due to fickle wireless environment. This is especially the case with passengers on long distance train (LDT) to connect onto the Internet. To improve the service quality of wide range wireless networks, we present the DragonNet protocol with its implementation. The DragonNet system is a chained gateway which consists of a group of interlinked DragonNet routers working specifically for mobile chain transport systems. The protocol makes use of the spatial diversity of wireless signals that not all spots on a surface see the same level of radio frequency radiation. In the case of a LDT of around 500 meters, it is highly possible that some of the spanning routers still see sound signal quality, when the LDT is partially blocked from wireless Internet. DragonNet protocol fully utilizes this feature to amortize single point router failure over the whole router chain by intelligently rerouting traffics on failed ones to sound ones. We have implemented the DragonNet system and tested it in real railways over a period of three months. Our results have pinpointed two fundamental contributions of DragonNet protocol. First, DragonNet significantly reduces average temporary communication blackout (i.e. no Internet connection) to 1.5 seconds compared with 6 seconds that without DragonNet protocol. Second, DragonNet efficiently doubles the aggregate throughput on average.

A fuzzy set paradigm for conceptual system design evaluation (1994)

A structured and disciplined system engineering process is essential for the efficient and effective development of products and systems which are both responsive to customer needs and globally competitive. Rigor and discipline during the later life-cycle phases of design and development (preliminary and detailed) cannot compensate for an ill-conceived system concept and for premature commitments made during the conceptual design phase. This significance notwithstanding, the nascent stage of system design has been largely ignored by the research and development community. This research is unique. It focuses on conceptual system design and formalizes analysis and evaluation activities during this important life-cycle phase. The primary goal of developing a conceptual design analysis and evaluation methodology has been achieved, including complete integration with the system engineering process. Rather than being a constraint, this integration led to a better definition of conceptual design activity and the coordinated progression of synthesis, analysis, and evaluation. Concepts from fuzzy set theory and the calculus of fuzzy arithmetic were adapted to address and manipulate imprecision and subjectivity. A number of design decision aids were developed to reduce the gap between commitment and project specific knowledge, to facilitate design convergence, and to help realize a preferred system design concept.

Is ECG‐guidance a helpful method to correctly position a central venous catheter during prehospital emergency care? (2005)

Background: Insertion of a central venous catheter (CVC) in an emergency situation is challenging and may be potentially associated with more complications. Because CVC positioning by ECG‐guidance may help to decrease the frequency of a malpositioned catheter, we decided to prospectively evaluate the usefulness of positioning a CVC by ECG‐guidance during prehospital emergency care. Methods: Prospective observational study during which all patients requiring CVC placement during prehospital care were included. We compared two periods of 1 year during which CVCs were inserted without and then with the help of ECG‐guidance. Results: Eighty successive patients were included. We observed a significant reduction of incorrectly positioned CVCs with ECG‐guidance (13% vs. 38%, P &lt; 0.05) and a decreased number of chest X‐rays needed to verify the position of the CVC (40 vs. 54, P &lt; 0.05). Conclusion: ECG‐guidance is a safe and feasible technique which significantly improved the rate of CVCs correctly positioned during prehospital emergency care.
Biotemplated Synthesis of Single-Crystalline W18O49@C Core−Shell Nanorod and Its Capacitance Properties (2008)

Single-crystalline W18O49@C core−shell nanorods were prepared by a simple and economical method using a naturally occurring biopolymer, chitosan, as a template. The core−shell nanorods were characterized by CHN, XRD, BET, SEM, and HRTEM analysis. The HRTEM shows that each nanorod is made up of bundle of tiny nanorods with diameters of 2−3 nm. The capacitance properties were studied in 1 M H2SO4 and 1 M Na2SO4 using cyclic voltammetry. W18O49@C prepared at 973 K shows higher capacitance compared to W18O49@C prepared at 1023 K in both acid and aqueous mediums.
New Approaches to the Prevention of Influenza (1975)

Summary. More than 30 years after development of the first effective influenza vaccine, influenza remains virtually uncontrolled by human intervention. The explanation of this paradox is to be found in the nature of the causative virus, which is unique among infectious agents in its capacity for rapid and frequent intigenic changes. Therefor, the limited effectiveness of present day vaccines is less a problem in immunology than it is in the rapid obsolescence of vaccines. The continual need for “updating” of vaccines presents recurrent problems attendant upon the selection, development and production of new vaccine virus strains. Another problem, common also to most other inactivated vaccines, is the transient immunity induced by parenteral administration of conventional inactivated influenza vaccines, even if they are homotypic to the challenge virus. Thus, the problem of influenza immunization requires new approaches, and a variety of new currently under study. These approaches include: Better standardization of vaccines and increase in antigenic mass. This prosaic but necessary step has reduced one cause of vaccine failure of the past‐i.e. insufficient antigen. Better purification of vaccines to reduce toxicity related to non‐viral materials. Induction of local immunity by topical application of vaccine to the respiratory tract. It is logical to induce immunity at the site of subsequent challenge (as with live poliovirus vaccine), although the relative importance of humoral and local immunity in influenza has been insufficiently studied. Such immunity can be stimulated either by live or inactivated vaccines, but much more effectively by the former. Laboratory selection of antigenic mutants in anticipation of their selection in nature. This approach attempts to simulate in the laboratory the evolution of strain in the laboratory the evolution of strains in nature by passage of virus with antiserum. The objective is to accelerate the selection process so that a pan‐antigenic vaccine virus is derived that can protect against future variants of the subtye. Gentic manipulation of viruses by recombination and induction and selection of mutants.(The creation of new viruses with desirable properties.)

Valorisation d’une souche bactérienne issue du «Kopara» (Tuamotu, PF) (2014)

Une souche bacterienne identifiee comme Paracoccus zeaxanthinifaceans subsp. payriae a ete isolee a partir de prelevements realises sur des tapis microbiens « kopara » sur les atolls de Polynesie francaise. Cette souche produit, en conditions de laboratoire, un exopolysaccharide (EPS), un pigment, et des polyhydroxyalcanoates (PHA). L’EPS, de haut poids moleculaire et hautement sulfate, presente une forte activite amincissante laissant presager de son developpement rapide en cosmetique. Ses capacites de retention de cations metalliques tels que le cuivre (Qmax = 625 mg g-1) et le fer (Qmax = 385 mg g-1) permettent d’envisager un developpement dans les domaines de l’environnement et de la sante. Le pigment associe a cet EPS lors de la fermentation, est compose a plus de 90% de all-trans-zeaxanthine de configuration absolue (3R, 3’R). Ce compose optiquement actif est tres recherche pour la protection de l’œil et de la peau face aux rayonnements UV. Enfin les plastiques biodegradables que representent les PHA sont d’un interet majeur en termes d’environnement. Leur mode de production ecologique pourrait leur permettre de se substituer a courte echeance aux plastiques synthetiques.
Isolation and characterization of leukosialin, a major sialoglycoprotein on human leukocytes. (1986)

A major sialoglycoprotein (previously called gp105) on the human erythroleukemic cell line K562 was purified, and specific antibodies were raised in a rabbit. A number of different hematopoietic cell lines belonging to erythroid, myeloid, T-lymphoid, and B-lymphoid cell lineages were found to possess glycoproteins that were immunoprecipitated by these antibodies. However, the apparent molecular weights differed between cell lines, ranging from 113,000 to 150,000. In almost all cases, the immune precipitated molecule corresponded to the major sialoglycoprotein of the respective cell. Pulse-chase experiments showed that all cells produced an early precursor form of the molecule of 54 kDa, which was susceptible to endo-beta-N-acetylglucosaminidase H to give an apoprotein of 52 kDa. Neuraminidase treatment of the mature forms resulted in a characteristic decrease of the mobility in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (apparent molecular weights from 150,000 to 183,000). Amino acid analysis of the glycoprotein isolated from HL-60 cells showed a high content of serine, threonine, and proline, and the carbohydrate composition was compatible with the presence of a large number (approximately 90) of O-linked carbohydrate chains. The name leukosialin is proposed for this sialoglycoprotein, which seems to be widely distributed, but differently glycosylated, on leukocytes with diverse functions. In the following paper (Carlsson, S.R., Sasaki, H., and Fukuda, M. (1986) J. Biol. Chem. 261, 12787-12795), we demonstrate that the structures of O-linked oligosaccharides vary significantly depending on the cells from which leukosialin was isolated.
Combined deficiency of ABCA1 and ABCG1 promotes foam cell accumulation and accelerates atherosclerosis in mice (2007)

HDLs protect against the development of atherosclerosis, but the underlying mechanisms are poorly understood. HDL and its apolipoproteins can promote cholesterol efflux from macrophage foam cells via the ATP-binding cassette transporters ABCA1 and ABCG1. Experiments addressing the individual roles of ABCA1 and ABCG1 in the development of atherosclerosis have produced mixed results, perhaps because of compensatory upregulation in the individual KO models. To clarify the role of transporter-mediated sterol efflux in this disease process, we transplanted BM from Abca1(-/-)Abcg1(-/-) mice into LDL receptor-deficient mice and administered a high-cholesterol diet. Compared with control and single-KO BM recipients, Abca1(-/-)Abcg1(-/-) BM recipients showed accelerated atherosclerosis and extensive infiltration of the myocardium and spleen with macrophage foam cells. In experiments with isolated macrophages, combined ABCA1 and ABCG1 deficiency resulted in impaired cholesterol efflux to HDL or apoA-1, profoundly decreased apoE secretion, and increased secretion of inflammatory cytokines and chemokines. In addition, these cells showed increased apoptosis when challenged with free cholesterol or oxidized LDL loading. These results suggest that the combined effects of ABCA1 and ABCG1 in mediating macrophage sterol efflux are central to the antiatherogenic properties of HDL.
An Analysis of Cavitated Wave Journal Bearings (2006)

A numerical investigation of the two dimensional flow in cavitated wave journal bearings is presented in this paper. An algorithm based on an upwind differencing scheme combined with a Rosenbrock integrator was used to simulate bearing cavitation. The algorithm, which conserves mass throughout the bearing, automatically implements JFO boundary conditions at rupture and at reformation. The numerical predictions are compared with numerical results obtained with other algorithms.Copyright © 2006 by ASME
A Multiple Model Approach to Track Head Orientation With Delta Quaternions (2012)

Virtual reality and augmented reality environments using helmet-mounted displays create a sense of immersion by closely coupling user head motion to display content. Delays in the presentation of visual information can destroy the sense of presence in the simulation environment when it causes a lag in the display response to user head motion. The effect of display lag can be minimized by predicting head orientation, allowing the system to have sufficient time to counteract the delay. In this paper, anew head orientation prediction technique is proposed that uses a multiple delta quaternion (DQ) extended Kalman filter to track angular head velocity and angular head acceleration. This method is independent of the device used for orientation measurement, relying on quaternion orientation as the only measurement data. A new orientation prediction algorithm is proposed that estimates future head orientation as a function of the current orientation measurement and a predicted change in orientation, using the velocity and acceleration estimates. Extensive experimentation shows that the new method improves head orientation prediction when compared to single filter DQ prediction.
Impaired Fungicide Activity in Plants Blocked in Disease Resistance Signal Transduction (1998)

Fungicide action is generally assumed to be dependent on an antibiotic effect on a target pathogen, although a role for plant defense mechanisms as mediators of fungicide action has not been excluded. Here, we demonstrate that in Arabidopsis, the innate plant defense mechanism contributes to the effectiveness of fungicides. In NahG and nim1 (for noninducible immunity) Arabidopsis plants, which normally exhibit increased susceptibility to pathogens, the fungicides metalaxyl, fosetyl, and Cu(OH)2 are much less active and fail to control Peronospora parasitica. In contrast, the effectiveness of these fungicides is not altered in Arabidopsis mutants defective in the ethylene or jasmonic acid signal transduction pathways. Application of the systemic acquired resistance activator benzothiadiazole (BTH) in combination with these fungicides results in a synergistic effect on pathogen resistance in wild-type plants and an additive effect in NahG and BTH-unresponsive nim1 plants. Interestingly, BTH treatment normally induces long-lasting pathogen protection; however, in NahG plants, the protection is transient. These observations suggest that BTH treatment can compensate only partially for an impaired signal transduction pathway and support the idea that pathogen defense mechanisms are under positive feedback control. These observations are strikingly reminiscent of the reduced efficacy of antifungal agents in immunocompromised animals.
Recrystallization in Aqueous Fructose Solutions as Affected by Locust Bean Gum (1996)

ABSTRACT Rates of ice recrystallization were measured in aqueous fructose solutions containing locust bean gum (LBG). The effects of temperature, ice phase volume and LBG concentration were determined. Decreasing temperature reduced the recrystallization rate: the dependency followed Williams Landell Ferry kinetics. An increase in ice phase volume resulted in an increase in the recrystallization rate. Addition of LBG reduced the recrystallization rate up to a concentration of 0.3% (w/w); further addition resulted in no further decrease. The hypothesized mechanism of action of LBG is via weak adsorption of the polysaccharide to the ice crystal. Freeze concentrated solution viscosity did not correlate with observed recrystallization rates.

Induction thermography on CFRP and the role of anisotropy (2018)

Experiments were performed by induction thermography on carbon fibre reinforced plates. Uni-axial, bi-axial materials as well as woven fabric were studied. The uni-axial material was investigated as a function of the fibre orientation angle and showed heating far away from the inductor and heating patterns with local minima. The occurrence of minima was explained by induction current cancellation effects. The experimentally measured thermal contrast patterns were confirmed by the results of numerical simulations. Fiber breakage could be detected better by induction thermography than by optically excited thermography.
Nucleoside reverse transcriptase inhibitors and HIV mutagenesis (2003)

Potent antiretroviral therapy (ART) of HIV-1 infection with anti-retroviral drugs consisting of nucleoside reverse transcriptase inhibitors(NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs)and protease inhibitors (PIs) has dramatically reduced the rate ofHIV- and AIDS-related morbidity and mortality. The lack of patientcompliance to drug administration results in suboptimal therapy. Sub-optimal drug therapy can lead to drug resistance, which limits theclinical benefit of drug treatment and can select for new variantviruses with altered virulence and tropism.In this leading article, we discuss literature that shows a correlationbetween the evolution of drug resistance and increased HIV and otherpathogen mutation rates. In the case of HIV, NRTIs and NRTI drugresistance can increase HIV mutation rates, and can act together tofurther increase these rates. These increased mutation rates predictthat drug failure during initial treatment could increase the probabilityof subsequent drug therapy failures due to the selection of mutatorstrains. However, increased mutagenesis of HIV by NRTIs could beviewed as an advantage in therapies directed at extinguishing virusinfectivity by lethal mutagenesis.

Synthesis of α‐MoC1−x Nanoparticles with a Surface‐Modified SBA‐15 Hard Template: Determination of Structure–Function Relationships in Acetic Acid Deoxygenation (2016)

Surface modification of mesoporous SBA-15 silica generated a hydrophobic environment for a molybdenum diamine (Mo-diamine) precursor solution, enabling direct growth of isolated 1.9±0.4 nm α-MoC1-x nanoparticles (NPs) inside the pores of the support. The resulting NP catalysts are bifunctional, and compared to bulk α-MoC1-x and β-Mo2 C, the NPs exhibit a greater acid-site:H-site ratio and a fraction of stronger acid sites. The greater acid-site:H-site ratio results in higher decarbonylation (DCO) selectivity during acetic acid hydrodeoxygenation (HDO) reactions, and the stronger acid sites lead to higher activity and ketonization (KET) selectivity at high temperatures. The hard-templating synthetic method could be a versatile route toward carbide NPs of varying size, composition, and phase, on a range of mesoporous oxide supports.
