A 32 × 32 BIT multiplier using multiple-valued MOS current-mode circuits (1987)

In the conventional array multiplier, the multiplication speed is restricted by the carry propagation. On the other hand, it is difficult to realize a compact multiplier in the high-speed multiplier such as the Wallace tree multiplier, because its layout is complicated and a large area is required for the interconnections. In such situations, the use of multiple-valued logic in conventional digital systems has potential advantages of which one of the most important is the reduction in interconnections [1]. However very few types of chips using multiple-valued logic have been fabricated for practical applications[2]. This paper presents a high-speed compact multiplier based on the radix-4 signed-digit (SD) number system and a completely new implementation using multiple-valued MOS current-mode circuits[3].
Reliability improvements in solder bump processing for flip chips (2002)

A plated solder-bump process used for the manufacture of high-reliability flip chips is described. Characterization work done to improve the process manufacturability and the resulting product reliability gains are reviewed. Two detailed studies of the thin-film deposition conditions and the Cu pedestal plating parameters are described. Recommendations implemented as a result of these studies have reduced the bump-interconnect-failure level from a defect rate of approximately 500 p.p.m. to <10 p.p.m. Excellent temperature cycling performance of assembled hybrids was obtained. The process has been used in high-volume production to manufacture ICs used in automobiles (under-hood application). In process capability has improved from a C/sub p/<1 to C/sub p/>1.5. This work highlights the need and the benefits of detailed characterization, which results in more robust manufacturing processes and eventually in more reliable product performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Pleiotropic regulation of vascular smooth muscle tone by cyclic GMP-dependent protein kinase. (1994)

Cyclic GMP (cGMP) mediates vascular smooth muscle relaxation in response to nitric oxide and atrial natriuretic peptides. One mechanism by which cGMP decreases vascular tone is by lowering cytosolic Ca2+ levels in smooth muscle cells. Although mechanisms by which cGMP regulates cytosolic Ca2+ are unclear, an important role for the cGMP-dependent dependent protein kinase in regulating Ca2+ has been proposed. Cyclic GMP-dependent protein kinase has been shown to regulate several pathways that control cytosolic Ca2+ levels: inositol 1,4,5-trisphosphate production and action, Ca(2+)-ATPase ATPase activation, and activation of Ca(2+)-activated K+ channels. The pleiotropic action of cGMP-dependent protein kinase is proposed to occur through the phosphorylation of important proteins that control several signaling pathways in smooth muscle cells. One potential target for cGMP-dependent protein kinase is the class of okadaic acid-sensitive protein phosphatases that appears to regulate K+ channels among other potentially important events to reduce cytosolic Ca2+ and tone. In addition, cytoskeletal proteins are targets for cGMP-dependent protein phosphorylation, and it is now appreciated that the cytoskeleton may play a key role in signal transduction.

A nondestructive acoustic electric field probe (1980)

A new method is described for the nondestructive measurement of electric field and space-charge distributions inside solid or liquid insulators by using a nonstructured acoustic pulse. The integral equation is derived for the response of the dielectric during propagation of an acoustic pulse and some acoustic measurements of electric fields and space charge inside transformer oil and polymethylmethacrylate plastic are described.
Data Governance and Stewardship: Designing Data Stewardship Entities and Advancing Data Access (2010)

U.S. health policy is engaged in a struggle over access to health information, in particular, the conditions under which information should be accessible for research when appropriate privacy protections and security safeguards are in place. The expanded use of health information-an inevitable step in an information age-is widely considered be essential to health system reform. Models exist for the creation of data-sharing arrangements that promote proper use of information in a safe and secure environment and with attention to ethical standards. Data stewardship is a concept with deep roots in the science and practice of data collection, sharing, and analysis. Reflecting the values of fair information practice, data stewardship denotes an approach to the management of data, particularly data that can identify individuals. The concept of a data steward is intended to convey a fiduciary (or trust) level of responsibility toward the data. Data governance is the process by which responsibilities of stewardship are conceptualized and carried out. As the concept of health information data stewardship advances in a technology-enabled environment, the question is whether legal barriers to data access and use will begin to give way. One possible answer may lie in defining the public interest in certain data uses, tying provider participation in federal health programs to the release of all-payer data to recognized data stewardship entities for aggregation and management, and enabling such entities to foster and enable the creation of knowledge through research.
THE MELANOCYTE MODEL (1971)

The effect of various agents that cause metaphase arrest in dividing cells was studied on the rapid reversible darkening of frog skin under the influence of melanocyte-stimulating hormone (MSH). Darkening is due to dispersion of melanin granules in melanocytes and is thought to be accompanied by a gel-to-sol cytoplasmic transformation. After subsequent washing the skin lightens, with aggregation of melanin granules and cytoplasmic gelation. As previously shown with colchicine, preincubation of frog skin with vinblastine, vincristine, or colcemid produced an increase in darkening induced by MSH, as compared to control skins, and a dosage-dependent inhibition of subsequent lightening. Preincubation with each drug, without subsequent MSH, produced a gradual, irreversible, dosage-dependent darkening over several hours. On a molar basis, the relative strength of the various agents was vinblastine > vincristine > colcemid > colchicine; vinblastine was about 100 times stronger than colchicine. Preincubation of frog skin with griseofulvin, followed by washing, had no subsequent effects on darkening or lightening. However, effects similar to those of the Colchicum and Vinca alkaloids were seen if griseofulvin was kept in the ambient media. These effects were rapidly reversible on removal of the drug from the media. These findings support the melanocyte model originally proposed for the action of colchicine, and emphasize certain facts that models of melanin granule movement will have to accommodate.
Adaptive RACH congestion management to support M2M communication in 4G LTE networks (2013)

Machine to machine communication (M2M) or machine type communication (MTC) facilitates communication of two network enabled devices, without any human intervention, to take some intelligent decision based on the interaction of devices. Because of ubiquitous coverage and global connectivity, cellular networks are playing a major role in the deployment of M2M communications. Due to some unique characteristics of M2M communication, supporting M2M applications in cellular networks is very challenging. One of such challenge is congestion in radio access network (RAN) during RACH procedure. This is because of the fact that there are large numbers of M2M devices which access the radio network at the same time. As a solution, we propose an adaptive RACH congestion management function (ARC) which specifies congestion handling method to be used by all M2M devices based on the current congestion condition of the network.
Aplicação do Apoio Multicritério à Decisão no Planejamento Urbano: (2020)

Os contextos relacionados a planejamentos e transportes apresentam complexidade para a tomada de decisão, por envolver vários atores e objetivos conflitantes. Neste sentido, foi proposta uma aplicação do Apoio Multicritério à Decisão, na área de planejamento urbano, especificamente, em um estudo para a escolha de pavimentos em uma cidade brasileira de porte médio. Foi desenvolvido em três etapas principais: estruturação do problema, avaliação das alternativas e recomendações. Avaliou-se alternativas em Concreto Asfáltico Usinado à Quente (CAUQ), em Peças Pré-moldadas de Concreto (PPC) e uma terceira em PPC dotada de estrutura para infiltração e armazenamento de águas pluviais. Como resultado, recomendou-se a alternativa em CAUQ. A aplicação do AMD proporcionou uma visão abrangente para a escolha de pavimentos urbanos, embasada no juízo de valores dos atores envolvidos; possibilitou a identificação das potencialidades e as limitações de cada pavimento; identificou valores que determinaram o melhor desempenho global do CAUQ e que se revelaram relevantes para a gestão pública. O modelo desenvolvido pode ser aplicado em outras áreas de transporte e planejamento urbano.
Compound semiconductor alloys. (1986)

Compound semiconductor alloys have the flexibility to design energy band gap and/or lattice constant at desired value. This advantage has made these materials important for fabricating many advanced semiconductor devices, such as laser diodes and high-speed electronic devices. The growing importance in application has stimulated both theoretical and experimental studies on the fundamental properties of compound semiconductor alloys, such as bond, clustering, and immiscibility. This article reviews recent progress in understanding these fundamental properties of III-V compound semiconductor alloys.
The Angular Momentum of Light (2012)

Recent developments in the angular momentum of light present fresh challenges to long established concepts and pave the way for new and wide-ranging applications. The scope for structured light such as optical vortices, in particular, now extends from microfluidics to quantum information. This is the first comprehensive edited collection dealing with light carrying spin and orbital angular momentum, covering both fundamental and applied aspects. Written by internationally leading specialists, the chapters have been compiled to reflect the latest scientific progress and to address the multitude of theoretical, experimental and technical issues associated with this vibrant and exciting field. The volume is an authoritative reference for academic researchers and graduate students engaged in theoretical or experimental study of optical angular momentum and its applications. It will also benefit professionals in physics, optics and optical engineering, chemistry and biology.
A Study on the Interaction of Rhodamine B with Methylthioadenosine Phosphorylase Protein Sourced from an Antarctic Soil Metagenomic Library (2013)

The presented study examines the phenomenon of the fluorescence under UV light excitation (312 nm) of E. coli cells expressing a novel metagenomic-derived putative methylthioadenosine phosphorylase gene, called rsfp, grown on LB agar supplemented with a fluorescent dye rhodamine B. For this purpose, an rsfp gene was cloned and expressed in an LMG194 E. coli strain using an arabinose promoter. The resulting RSFP protein was purified and its UV-VIS absorbance spectrum and emission spectrum were assayed. Simultaneously, the same spectroscopic studies were carried out for rhodamine B in the absence or presence of RSFP protein or native E. coli proteins, respectively. The results of the spectroscopic studies suggested that the fluorescence of E. coli cells expressing rsfp gene under UV illumination is due to the interaction of rhodamine B molecules with the RSFP protein. Finally, this interaction was proved by a crystallographic study and then by site-directed mutagenesis of rsfp gene sequence. The crystal structures of RSFP apo form (1.98 Å) and complex RSFP/RB (1.90 Å) show a trimer of RSFP molecules located on the crystallographic six fold screw axis. The RSFP complex with rhodamine B revealed the binding site for RB, in the pocket located on the interface between symmetry related monomers.
Synthesis of Bistable Compliant Four-Bar Mechanisms Using Polynomial Homotopy (2006)

In this paper we formulate and solve the synthesis equations for a compliant four-bar linkage with three specified equilibrium configurations in the plane. The kinematic synthesis equations as for rigid-body mechanisms are combined with equilibrium constraints at the flexure pivots to form design equations. These equations are simplified by modeling the joint angle variables in the equilibrium equations using sine and cosine functions. Polynomial homotopy continuation is applied to compute all of the design candidates that satisfy these design equations, which are refined using a Newton-Raphson technique. A numerical example demonstrates design methodology in which the homotopy solver obtained eight real solutions. Two of them provide two stable and one unstable equilibrium, and hence, can be used as the prototype of bistable compliant mechanisms.
Diallyl bisphenol A—novolac epoxy system cocured with bisphenol‐A‐bismaleimide—cure and thermal properties (2007)

Abstract Novolac epoxy (EPN)—2,2′‐diallyl bisphenol A (DABA) resin system was modified by cocuring it with bisphenol A bismaleimide (BMI). Molar concentration of BMI in the stochiometric blend of EPN and DABA was varied from 0.5 to 2.0. The cure optimization was done using DSC, IR spectroscopy, and rheological studies. The curing proceeded by phenol‐epoxy and Alder‐ene reactions. The performance of the ternary Epoxy‐Allyl phenolic‐Bismaleimide system was evaluated through their thermal and dynamic mechanical characterization. BMI improved the overall thermal stability and the modulus of the resultant composites. The increase in BMI concentration in the system resulted in enhanced glass transition temperature with a consequent improvement in high temperature performance typically estimated by their lap shear strength at high temperatures. The high temperature performance of the epoxy‐phenol‐bismaleimide (EPB) system was found to be far superior to the epoxy‐phenol (EP)system. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Electrical and Structural Properties of Co-Sputtered Tantalum–Aluminum Films (1969)

Tantalum-aluminum alloy films have been prepared by dc diode sputtering in argon from composite cathodes of tantalum sheet, with either inlaid strips of aluminum or aluminum strips attached to the tantalum. The aluminum coverage of the tantalum cathode has been varied between 0 and 85%. The coverages produced films ranging from 0% to about 85% aluminum, which are homogeneous in composition as determined by electron microprobe analysis. The as-deposited films of pure tantalum have either the bcc or β-Ta structure. Both structures form metastable solid solutions with up to 20 at.% aluminum. At 30% aluminum a new phase very similar to β-Ta appears. Between 30 at.% and 85 at.% aluminum a number of phases have been observed in the sputtered films but of the known bulk phases of the tantalum-aluminum system, Ta2Al, Ta17Al12, Ta12Al17, and TaAl3, only TaAl3 is observed in the sputtered films at 85% aluminum. The dependence of the electrical properties of tantalum-aluminum films on aluminum concentration has been determined. These properties include resistivity, dρ/dT, Hall coefficient, carrier concentration and type, and Hall mobility. Results on alloy films are compared to those reported for the bulk aluminides Ta2Al and TaAl3.

Terahertz Kerr and reflectivity measurements on the topological insulator<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mtext>Bi</mml:mtext></mml:mrow><mml:mn>2</mml:mn></mml:msub><mml:msub><mml:mrow><mml:mtext>Se</mml:mtext></mml:mrow><mml:mn>3</mml:mn></mml:msub></mml:mrow></mml:math> (2010)

We report the first terahertz Kerr measurements on bulk crystals of the topological insulator ${\text{Bi}}_{2}{\text{Se}}_{3}$. At $T=10\text{ }\text{K}$ and fields up to 8 T, the real and imaginary Kerr angle and reflectance measurements utilizing both linearly and circularly polarized incident radiation were measured at a frequency of 5.24 meV. A single fluid free carrier bulk response cannot describe the line shape. Data from one sample is quantitatively described by a surface state with a small mass and surprisingly large associated spectral weight. However, an alternative interpretation in terms of bulk carrier-density variations remains a possibility
Online monitoring of the Osiris reactor with the Nucifer neutrino detector (2016)

Originally designed as a new nuclear reactor monitoring device, the Nucifer detector has successfully detected its first neutrinos. We provide the second-shortest baseline measurement of the reactor neutrino flux. The detection of electron antineutrinos emitted in the decay chains of the fission products, combined with reactor core simulations, provides a new tool to assess both the thermal power and the fissile content of the whole nuclear core and could be used by the International Agency for Atomic Energy to enhance the safeguards of civil nuclear reactors. Deployed at only 7.2 m away from the compact Osiris research reactor core (70 MW) operating at the Saclay research center of the French Alternative Energies and Atomic Energy Commission, the experiment also exhibits a well-suited configuration to search for a new short baseline oscillation. We report the first results of the Nucifer experiment, describing the performances of the $\ensuremath{\sim}0.85\text{ }\text{ }{\mathrm{m}}^{3}$ detector remotely operating at a shallow depth equivalent to $\ensuremath{\sim}12\text{ }\text{ }\mathrm{m}$ of water and under intense background radiation conditions. Based on 145 (106) days of data with the reactor on (off), leading to the detection of an estimated $40760{\overline{\ensuremath{\nu}}}_{e}$, the mean number of detected antineutrinos is $281\ifmmode\pm\else\textpm\fi{}7(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}18(\mathrm{syst}){\overline{\ensuremath{\nu}}}_{e}/\mathrm{day}$, in agreement with the prediction of $277\ifmmode\pm\else\textpm\fi{}23{\overline{\ensuremath{\nu}}}_{e}/\mathrm{day}$. Because of the large background, no conclusive results on the existence of light sterile neutrinos could be derived, however. As a first societal application we quantify how antineutrinos could be used for the Plutonium Management and Disposition Agreement.
Electrochemical/chemical synthesis of nanostructured arrays of oxide cones or rings (2008)

Quasi-periodic supported arrays of sub-micron sized cones and rings consisting of mixed oxides of Al and Ta have been synthesized by anodization of Al(top)/Ta(bottom) bilayers sputtered on Si substrates and successive etching of the Al oxide and remaining Al-rich features. Exquisite control over the array morphology—cones or rings—is achieved by varying the thickness of the initial Ta layer, in the range of 5 to 50 nm. The nano-cones are formed by the Ta oxide fingering out of the Al oxide as a consequence of the higher mobility of Ta ions, leaving behind a ring with its center exposing the bare substrate.
Rate-Limiting Processes in the Formation of Single-Wall Carbon Nanotubes:  Pointing the Way to the Nanotube Formation Mechanism (2002)

Four rate-limiting processes for the formation of single-wall carbon nanotubes (SWCNT) could be identified by varying furnace temperature, gas type, and pressure in a pulsed-laser evaporation setup. One rate-limiting process accounts essentially for all relevant gas-pressure dependencies and can be quantitatively described using a single gas-specific constant. One thermally activated process is related to fullerene formation, whereas another process, following a T2-law, is discussed in terms of the diffusion of carbon through molten catalyst nanoparticles. The data provide strong support for an “undercooled melt” mechanism of nanotube formation.
Measurement of Driving Terms (2001)

In 2000 a series of MDs has been performed at the SPS to measure resonance driving terms. Theory predicts that these terms can be determined by harmonic analysis of BPM data recorded after applying single kicks at various amplitudes. Strong sextupoles were introduced to create a sizeable amount of nonlinearities. Experiments at injection energy (26 GeV) with single bunch as well as one experiment at 120 GeV with 84 bunches were carried out. The expected nonlinear content is compared to the experimenteal observation.
Encoding and Decoding of Auditory Signals in Relation to Human Speech and its Application to Human Cochlear Implants (1980)

A description of the optimal electrode and stimulus configuration, based on mathematical model simulation of (1) the mechanical conduction and (2) the mechanoelectrical transduction of the middle and inner ear, will be presented. It is assumed that a sensorineurally deaf patient, whose auditory nerve is at least partially intact, will be able to hear and understand, when an activation pattern in specific groups of remaining fibers of the hearing nerve can be reproduced in a manner equivalent to normal hearing. The placement of 2 bipolar concentric electrodes in the modiolus of the basal and middle cochlear turn in a deaf patient has provided the opportunity for testing of electrical hearing thresholds, differential thresholds, and electrode impedance changes over a 5-month period, with direct access to the electrodes through a skin window. The stimulator was housed in a pocket case to provide easy use in a daily environment. Bipolar pulses of 0.02-1.0 ms were triggered either by zero crossings or by a speech envelope controlled oscillator. It was found that loudness should be encoded by pulse amplitude or duration rather than by pulse repetition rate, since the charge per pulse was the primary variable of loudness sensation. The periodicity hearing allowed for electrical differential thresholds equivalent to or lower than the acoustical ones in normal persons in the 80- to 150-Hz region. For the optimal coding of speech, a multichannel system of 4-10 electrodes each for different nerve fiber groups will be necessary.
Behavior model based component search (2010)

We focus on the problem of searching components based on semantic queries on their provided interface. Although semantics-based search has long been advocated as a key enabler in the context of component-based software development and, more recently, service-oriented computing, no practical and scalable approach has been proposed yet. This paper presents a promising model-based search technique for interface behaviors based on operational specifications, called behavioral equivalence models (Bems). Semantic queries are expressed equationally, following an algebraic specification style. The search engine tries to match specifications against queries. This can be done quite efficiently by encoding Bems into relational models and queries into relational logic formulae, whose satisfiability is checked with the SAT-based constraint solver KodKod. We can report on an initial very promising assessment of the proposed technique, which has been applied to searching components in Java libraries providing container functionalities.
