Humidity and Temperature Effect on Frictional Properties of Mica and Alkylsilane Monolayer Self-Assembled on Mica (1998)

The effects of humidity and temperature on tribological properties of mica and of the octadecyltriethoxysilane (OTE) monolayer self-assembled on mica are studied by friction force microscopy under controlled environments. As the humidity increases, the friction force is observed to decrease for mica and to increase for OTE at low loads at room temperature. Despite their hydrophobicity, water can penetrate into OTE films to alter their molecular chain ordering and to detach the OTE molecules from the mica substrate. The occurrence of OTE film damage is manifested as a crossover point in the friction force curves. Heating the samples in the temperature range of 20−80 °C induces a negligible effect for both mica and OTE in low humidity. However, in high humidity, a distinctive change in friction was found. Most of the heating effect can be understood by a “local humidity” concept although various discrepancies still exist.
CAN QUANTUM MECHANICS HELP DISTRIBUTED COMPUTING? (2010)

We present a brief survey of results where quantum information processing is useful for performing distributed computation tasks. We describe problems that are impossible to solve using classical resources but that become feasible with the help of quantum mechanics. We also give examples where the use of quantum information significantly reduces the need for communication. The main focus of the survey is on communication complexity but we also address other distributed tasks.
Tumor induction by <i>Agrobacterium rhizogenes</i> involves the transfer of plasmid DNA to the plant genome (1982)

The DNA from tumors of Nicotiana glauca initiated by strains of Agrobacterium rhizogenes was shown to contain sequences that are homologous to the root-inducing (Ri) plasmid of the bacterium. Two independently established tumor lines contained a similar portion of the Ri-plasmid. The Ri-plasmid also hybridized to DNA fragments from uninfected N. glauca. A cosmid clone of the Ri-plasmid encompassing the region containing the Ri-plasmid sequences that are stably transferred to the plant also hybridized to the Ri-plasmid-related fragments found in uninfected plants. Five of six tumor lines tested produced a tumor-specific compound that is similar to agropine.

Enhancing Initial Release of Peptide from Poly(<i>d,l</i>-lactide-<i>co</i>-glycolide) (PLGA) Microspheres by Addition of a Porosigen and Increasing Drug Load (2000)

The objective of this study was to evaluate formulation variables such as drug load and addition of a porosigen in achieving an increased initial release of peptide from poly(d,l-lactide-co-glycolide) (PLGA) microspheres by altering carrier characteristics. Leuprolide acetate-loaded PLGA microspheres were prepared by a solvent-extraction-evaporation process and were characterized for their drug load (HPLC assay), bulk density (tapping method), size distribution (dynamic light scattering), specific surface area (Brunauer-Emmett-Teller [BET] analysis), surface morphology (scanning electron microscopy), in vitro drug release (at 37 degrees C), and in vivo efficacy (suppression of rat serum testosterone). Increasing the drug load, and adding various amounts of calcium chloride to organic and aqueous phases of the emulsion during processing yielded particles with increased porosity, lower bulk density, higher specific surface area, and accordingly higher initial release. In an animal model, these formulations showed a faster onset of testosterone suppression compared to microspheres without higher drug load or calcium chloride. The approaches employed in this study were found to be effective in avoiding the therapeutic lag phase usually observed with microencapsulated macromolecular drugs.
Synthesis of β- and γ-Carbolines by the Palladium/Copper-Catalyzed Coupling and Cyclization of Terminal Acetylenes (2002)

A variety of 3-substituted beta- and gamma-carbolines have been synthesized from N-substituted 3-iodoindole-2-carboxaldehydes and 2-bromoindole-3-carboxaldehydes, respectively. The coupling of these aldehydes with various terminal acetylenes with PdCl(2)(PPh(3))(2)/CuI as the catalyst readily affords the corresponding alkynylindole carboxaldehydes, which have subsequently been converted to the corresponding tert-butylimines and cyclized to beta- and gamma-carbolines by either copper-catalyzed or thermal processes.

Optimal Orientation Detection of Linear Symmetry (1987)

The problem of optimal detection of orientation in arbitrary neighborhoods is solved in the least squares sense. It is shown that this corresponds to fitting an axis in the Fourier domain of the n-dimensional neighborhood, the solution of which is a well known solution of a matrix eigenvalue problem. The eigenvalues are the variance or inertia with respect to the axes given by their respective eigen vectors. The orientation is taken as the axis given by the least eigenvaJ~e~ Moreover it is shown that the necessary computations can be pursued in the spatial domain without doing a Fourier transformation. An implementation for 2-D is presented. Two certainty measures are given corresponding to the orientation estimate. These are the relative or the absolute distances between the two eigenvalues, revealing whether the fitted axis is much better than an axis orthogonal to it. The result of the implementation is verified by experiments which confirm an accurate orientation estimation and reliable certainty measure in the presence of additive noise at high level as well as low levels.
Turbulence effects on a full‐scale 2.5 MW horizontal‐axis wind turbine under neutrally stratified conditions (2014)

Abstract A field experiment was carried out to study the unsteady behavior of an instrumented full‐scale 2.5 MW wind turbine under neutral conditions. The analysis focused on the structure of the instantaneous turbine power and strain at its foundation. A meteorological tower located 1.6 rotor diameters upstream of the turbine was used to characterize the turbulent flow. Mean velocity and temperature were steady during the 1 h period selected. The results suggest that the turbine power and foundation strain are modulated by atmospheric turbulence in a complex way. The spectral characteristics of both quantities exhibited three distinctive regions. Within the first region, defined by subrotor length scales, the turbine power was insensitive to the flow turbulence. In the intermediate region, with length scales up to those on the order of the atmospheric boundary layer thickness, the spectral contents of the power fluctuations Φ P and flow Φ U exhibit a non‐linear relationship of the form Φ P = G ( f )Φ U , where G ( f ) ∝ ( ∼ ) f − 2 is a transfer/damping function. In the third region, dominated by the very large scales of motions, the power fluctuations are found to be directly influenced by the flow. The strain also showed three regions, similar to the power fluctuations. However, it follows the structure of the inertial subrange of the turbulence at subrotor scales. Intermittent gusts were able to induce intermittent behavior on the turbine power. Finally, the flow and power correlation showed that the velocity at the hub height is the best descriptor of the flow turbulence within the rotor area.Copyright © 2014 John Wiley & Sons, Ltd.
Reliability and Photographic Equivalency of the Scar Cosmesis Assessment and Rating (SCAR) Scale, an Outcome Measure for Postoperative Scars (2016)

The SCAR scale is a reliable rating scale for postoperative linear scars, and photographs may reliably be used in lieu of live patient assessments. The SCAR scale therefore represents a reliable standard rating scale for postoperative scar cosmesis.
Human T-cell leukemia-lymphoma virus (HTLV) is in T but not B lymphocytes from a patient with cutaneous T-cell lymphoma. (1982)

A human type C retrovirus, designated HTLV, previously was isolated from or identified in some patients with leukemias and lymphomas of mature T lymphocytes. HTLV is genetically and serologically distinct from any known animal retroviruses. The absence of HTLV proviral sequences in DNA from normal humans showed that HTLV is not a ubiquitous endogenous (germ-line transmitted) virus of humans. Antibodies to HTLV core proteins have been identified in some people with T-cell neoplasias and are particularly prevalent in Japanese with adult T-cell leukemia, suggesting that HTLV is acquired horizontally. However, it was possible that HTLV is transmitted through the germ line of some (possibly rare) families and is then expressed in the HTLV- positive malignancies. An opportunity to study this question was provided by the development of several T-cell lines and a B-cell provided by the development of several T-cell lines and a B-cell line from one HTLV-positive patient with a cutaneous T-cell lymphoma. Here we report that HTLV proteins or nucleic acids (or both) are found in three independently derived T-cell lines, all shown by HLA typing to have originated from the patient. In contrast, the B-cell line, the identity of which was also ascertained by HLA typing, contained no detectable HTLV protein, RNA, or proviral DNA. Because the sensitivity of the latter assay is more than sufficient to detect one proviral equivalent per haploid genome, the results indicate that HTLV was not transmitted to this patient through the germ line but rather was acquired by infection.
Network Interactions and Performance of a Multifunction IEC 61850 Process Bus (2012)

New substation technology, such as nonconventional instrument transformers, and a need to reduce design and construction costs are driving the adoption of Ethernet-based digital process bus networks for high-voltage substations. Protection and control applications can share a process bus, making more efficient use of the network infrastructure. This paper classifies and defines performance requirements for the protocols used in a process bus on the basis of application. These include Generic Object Oriented Substation Event, Simple Network Management Protocol, and Sampled Values (SVs). A method, based on the Multiple Spanning Tree Protocol (MSTP) and virtual local area networks, is presented that separates management and monitoring traffic from the rest of the process bus. A quantitative investigation of the interaction between various protocols used in a process bus is described. These tests also validate the effectiveness of the MSTP-based traffic segregation method. While this paper focuses on a substation automation network, the results are applicable to other real-time industrial networks that implement multiple protocols. High-volume SV data and time-critical circuit breaker tripping commands do not interact on a full-duplex switched Ethernet network, even under very high network load conditions. This enables an efficient digital network to replace a large number of conventional analog connections between control rooms and high-voltage switchyards.

Fractalkine and inflammatory diseases (2005)

The migration of leukocytes into inflamed peripheral tissues and lymphoid organs involves a cascade of molecular events finely regulated by cell adhesion molecules and chemokines. Fractalkine/CX3CL1 is a membrane-bound chemokine that functions not only as a chemoattractant but also as an adhesion molecule, and is expressed on endothelial cells activated by proinflammatory cytokines. The fractalkine receptor, CX3CR1, is expressed on cytotoxic effector lymphocytes including NK cells and cytotoxic effector T cells (T(CE)), mature monocytes/macrophages, and mucosal dendritic cells, all of which play important roles in elimination of pathogens and cancer cells. Recently, accumulating evidence in both clinical studies and animal disease models has shown that fractalkine is also involved in the pathogenesis of various chronic inflammatory diseases, such as rheumatoid arthritis and atherosclerosis. This article reviews the unique functions of fractalkine and its pathophysiological roles in various clinical conditions.

Depth-map merging for Multi-View Stereo with high resolution images (2012)

By taking advantage of recent progress in patch match based stereo [1], we propose a depth-map merging based Multi-View Stereo (MVS) reconstruction method for large-scale scenes. Combining the strength of the accuracy of patch match stereo and the redundancy information provided by multiple views, our method can produce quite satisfactory MVS reconstruction results. Besides, the proposed method could be easily parallelized at image level, i.e., each depth-map is computed individually, which makes it suitable for large-scale scene reconstruction with high resolution images.
Resolution enhancement of saturated fluorescence emission difference microscopy (2016)

Fluorescence emission difference microscopy (FED) obtains resolution-enhanced images by subtracting acquired solid and doughnut confocal images. Because of the mismatch of the outer contours of the two subtraction components, negative values are inevitable in the conventional FED method, giving rise to deformations. In this study, by using a saturation effect, we obtain imaging results with a profile-extended solid and center-shrunken doughnut point spread function. Owing to the nonlinear effect, two better-matched saturated images not only eliminate the deformations, but also enhance the resolving ability and signal to noise ratio compared to conventional FED. Simulations based on the saturated model of rhodamine 6G, as well as experiments on biological samples, are presented to verify the capability of the proposed concept, while experimental results show the unprecedented resolving ability of the saturated FED method.
Dark and photoconductivity behavior of C60 thin films sandwiched with metal electrodes (1992)

Sandwich cells of C60 thin film with a front Al electrode reveal considerable rectifying effects and large photocurrents (quantum yields ≤54%) under air. The action spectra closely follow the optical absorption spectrum of the film. The relationship between photocurrent (Jph) and incident light intensity (Pin) changes from Jph∝(Pin)0.95±0.05 at Pin&lt;3×10−7 W/cm2 to Jph∝(Pin)0.53±0.03 at higher Pin, suggesting that the photocurrent is controlled by the interaction of excitons with impurity sites at surface and near-surface of C60 in the absence and presence of bimolecular recombination depending on light intensity.

Dementia and marriage (2016)

Marriage is known to have a beneficial effect on dementia risk. More than two million people aged between 50 and 74 years were included in this study, and were followed for up to ten years. Findings support the association between marital status and dementia, showing similar effects for men and women once socioeconomic factors had been taken into account. There are several possible reasons for this association.
Efficient synthesis of optically active 2-amino-2'-diphenylphosphino-1,1'-binaphthyl and its derivatives (2000)

Optically active 2-amino-2'-diphenylphosphino-1,1'-binaphthyls having various functional groups, such as amino, alkoxycarbonylamino, acylamino, mono- and dialkylamino, and sulfonylamino at C2 position were prepared. The key intermediate of the above aminophosphines was 2-carbamoyl-2'-diphenylphosphinyl-1,1'-binaphthyl synthesized from optically active 2-cyano-2'-diphenylphosphinyl-1,1'-binaphthyl. The transformation of the carbamoyl group to an amino group was effected by the Hofmann reaction.Key words: aminophosphine ligand, Hofmann reaction, optically active phosphine ligand.
The Goblin Quadtree (1988)

The Goblin quadtree is a new and simple data structure for representing spatial information. It stores a single pointer for each block of four nodes and average values at non-terminal nodes, enabling efficient depth-first traversal to any given level. The pointers are easy to generate and use, as demonstrated by algorithms for building and displaying Goblin quadtrees. The features of this new representation make it particularly suitable for geographic data. The concept of using a dominant value as the average value is explored, and is shown to be advantageous for quadtree display and storage.
Safe Vertical Clearances for Overhead Power Lines (1990)

An efficient, user-friendly PC enhancement of an old method is presented for examining vertical clearances in overhead powerlines. Based, on simple measurements and mathematics, it is more credibly accurate than sophisticated analysis requiring accurate survey. It is useful for assessing alternatives in upgrading existing lines or in conceptual design for new lines.
Kinetic and Thermodynamic Analysis of 9-<i>cis-</i>Retinoic Acid Binding to Retinoid X Receptor α (1999)

The interaction of retinoid X receptor alpha with 9-cis-retinoic acid was studied using stopped-flow fluorescence spectroscopy. Transient kinetic analyses of this interaction suggest a two-step binding mechanism involving a rapid, enthalpically driven pre-equilibrium followed by a slower, entropically driven reaction that may arise from a conformational change within the ligand binding domain of the receptor. The assignment of this kinetic mechanism was supported by agreement between the overall equilibrium constant, Kov, derived from kinetic studies with that determined by equilibrium fluorescence titrations. Although these analyses do not preclude ligand-induced alteration in the oligomerization state of the receptor in solution, the simplest model that can be applied to these data involves the stoichiometric interaction of 9-cis-retinoic acid with retinoid X receptor alpha monomers.
ATM switching system architecture and implementation of B-ISDN (2002)

The author describes an asynchronous transfer mode (ATM) switching system that used high-speed ICs to provide multimedia traffic control and media-specific service adaptation. The architecture for ATM switching, which is called multi-stage self-routing (MSSR), is based on the self-routing switching principle of K. Hajikano et al. (1988). It is constructed by connecting self-routing switching modules in a three-stage link configuration. This system is a first implementation of the broadband-integrated services digital network (B-ISDN).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Single-ended transceiver design techniques for 5.33Gb/s graphics applications (2009)

Graphics processing is the driving force behind the demand for high-bandwidth DRAMs. Accelerating the pace of bandwidth improvement, fifth-generation graphics DDRs will operate at data rates up to 5.33 Gb/s, and support single-ended signaling for low pin-count. A significant design challenge is to ensure proper signal transmission over single-ended wires at rates previously attainable only with differential pairs. We present single-ended transceiver design techniques for 5.33 Gb/s operation. In addition to the receiver and transmitter, a CML-to-CMOS converter and an integrated serializer/level-shifter are described. The circuits are fabricated in 0.13 mum 1.2 V CMOS. The chip area is 5.7times7.0mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and is housed in a quadratic BGA package with 289 balls.
Mechanistic Investigation of Bis(imino)pyridine Manganese Catalyzed Carbonyl and Carboxylate Hydrosilylation (2017)

We recently reported a bis(imino)pyridine (or pyridine diimine, PDI) manganese precatalyst, (<sup>Ph2PPr</sup>PDI)Mn (1), that is active for the hydrosilylation of ketones and dihydrosilylation of esters. In this contribution, we reveal an expanded scope for 1-mediated hydrosilylation and propose two different mechanisms through which catalysis is achieved. Aldehyde hydrosilylation turnover frequencies (TOFs) of up to 4900 min<sup>-1</sup> have been realized, the highest reported for first row metal-catalyzed carbonyl hydrosilylation. Additionally, 1 has been shown to mediate formate dihydrosilylation with leading TOFs of up to 330 min<sup>-1</sup>. Under stoichiometric and catalytic conditions, addition of PhSiH<sub>3</sub> to (<sup>Ph2PPr</sup>PDI)Mn was found to result in partial conversion to a new diamagnetic hydride compound. Independent preparation of (<sup>Ph2PPr</sup>PDI)MnH (2) was achieved upon adding NaEt<sub>3</sub>BH to (<sup>Ph2PPr</sup>PDI)MnCl<sub>2</sub> and single-crystal X-ray diffraction analysis revealed this complex to possess a capped trigonal bipyramidal solid-state geometry. When 2,2,2-trifluoroacetophenone was added to 1, radical transfer yielded (<sup>Ph2PPr</sup>PDI·)Mn(OC·(Ph)(CF<sub>3</sub>)) (3), which undergoes intermolecular C-C bond formation to produce the respective Mn(II) dimer, [(μ-O,N<sub>py</sub>-4-OC(CF<sub>3</sub>)(Ph)-4-H-<sup>Ph2PPr</sup>PDI)Mn]<sub>2</sub> (4). Upon finding 3 to be inefficient and 4 to be inactive, kinetic trials were conducted to elucidate the mechanisms of 1- and 2-mediated hydrosilylation. Varying the concentration of 1, substrate, and PhSiH<sub>3</sub> revealed a first order dependence on each reagent. Furthermore, a kinetic isotope effect (KIE) of 2.2 ± 0.1 was observed for 1-catalyzed hydrosilylation of diisopropyl ketone, while a KIE of 4.2 ± 0.6 was determined using 2, suggesting 1 and 2 operate through different mechanisms. Although kinetic trials reveal 1 to be the more active precatalyst for carbonyl hydrosilylation, a concurrent 2-mediated pathway is more efficient for carboxylate hydrosilylation. Considering these observations, 1-catalyzed hydrosilylation is believed to proceed through a modified Ojima mechanism, while 2-mediated hydrosilylation occurs via insertion.
