Activacion de enlaces c-c y c-h con reactivos portadores de yodo. Reacciones de oxidación de alcoholes: procesos estequiometricos y cataliticos (2003)

En la presente memoria se describen distintos procesos de oxidación estequiométricos y catalíticos que implican a moléculas orgánicas tales como alcoholes y alcanos. Las transformaciones que se recogen, se han llevado a cabo haciendo uso de reactivos halogenados y prestando un interés especial al empleo de compuestos de yodo. En el primer capítulo, se revisan los aspectos esenciales de la reactividad del tetrafluoroborato de bis (piridina) yodonio (i) (ipy2bf4) en el ámbito de diversas reaccines iónicas de adición y sustitución. El capítulo 2 se ha dividido en dos partes. En la primera de ellas se presentan los resultados obtenidos en el contexto de las reacciones de b-fragmentación de cicloalcanoles empleando ipy2bf4 como oxidante. La transformación origina sistemas -yodofuncionalizados, y constituye el primer ejemplo de un proceso fotoquímico eficaz en el contexto de este reactivo de yodación. La segunda parte de este capítulo está relacionada con las reacciones de activación de enlaces c-h en hidrocarburos saturados. En este sentido, el empleo de compuestos de yodo hipervalente permite obtener productos de mono y de bifuncionalización diasteroselectiva de manera satisfactoria. En el tercer capítulo se discuten diversos aspectos relacionados con las reacciones de oxidación de alcoholes, de acuerdo a distintas aproximaciones experimentales. En la primera parte de este capítulo, se presentan los resultados obtenidos empleando ipy2bf4 en presencia de distintos aditivos. Los resultados preliminares avalan la capacidad oxidante de este reactivo, ampliando su campo de aplicación. En la segunda parte, se recogen los resultados iniciales que se han encontrado en la utilización de sales inorgánicas como catalizadores en este tipo de reacciones de oxidación en medio acuoso. Los experimentos ensayados se han diseñado y ejecutado sobre la base de consideraciones biológicas, y proporcionan una alternativa económica
Theoretical Insights into Pyridinium-Based Photoelectrocatalytic Reduction of CO2 (2012)

The role of pyridinium cations in electrochemistry has been believed known for decades, and their radical forms have been proposed as key intermediates in modern photoelectrocatalytic CO(2) reduction processes. Using first-principles density functional theory and continuum solvation models, we have calculated acidity constants for pyridinium cations and their corresponding pyridinyl radicals, as well as their electrochemical redox potentials. Contrary to previous assumptions, our results show that these species can be ruled out as active participants in homogeneous electrochemistry. A comparison of calculated acidities and redox potentials indicates that pyridinium cations behave differently than previously thought, and that the electrode surface plays a critical (but still unknown) role in pyridinium reduction. This work substantially alters the mechanistic view of pyridinium-catalyzed photoelectrochemical CO(2) reduction.

Selection of Reliable Reference Genes in Caenorhabditis elegans for Analysis of Nanotoxicity (2012)

Despite rapid development and application of a wide range of manufactured metal oxide nanoparticles (NPs), the understanding of potential risks of using NPs is less completed, especially at the molecular level. The nematode Caenorhabditis elegans (C.elegans) has been emerging as an environmental model to study the molecular mechanism of environmental contaminations, using standard genetic tools such as the real-time quantitative PCR (RT-qPCR). The most important factor that may affect the accuracy of RT-qPCR is to choose appropriate genes for normalization. In this study, we selected 13 reference gene candidates (act-1, cdc-42, pmp-3, eif-3.C, actin, act-2, csq-1, Y45F10D.4, tba-1, mdh-1, ama-1, F35G12.2, and rbd-1) to test their expression stability under different doses of nano-copper oxide (CuO 0, 1, 10, and 50 µg/mL) using RT-qPCR. Four algorithms, geNorm, NormFinder, BestKeeper, and the comparative ΔCt method, were employed to evaluate these 13 candidates expressions. As a result, tba-1, Y45F10D.4 and pmp-3 were the most reliable, which may be used as reference genes in future study of nanoparticle-induced genetic response using C.elegans.
Low bit-rate audio coding with hybrid representations. (1999)

We present a general audio coder based on a structural decomposition: the signal is expanded into three features: its harmonic part, the transients and the remaining part (referred as the &amp;quot;noise&amp;quot;). The first two of these &amp;quot;layers&amp;quot; can be very efficiently encoded in a well-chosen basis. The noise is by construction modelized as a gaussian (colored) random noise. Furthermore, this decomposition allows a good time-frequency psycoacoustic modeling, as it dircetly provides us with the tonal and nontonal part of the signal.
Automation in Technical Services: (1991)

Automation has changed both procedures and cost distribution in technical services. Accommodation to the needs of automated systems requires a complete rethinking of procedures and responsibilities, and a much closer assignment of the latter. The creation and maintenance of an online database requires close attention to standards, particularly to authority control. Acquisitions and cataloging staffs need to work together. It also needs closer cooperation between technical and public service units. While more expenditure for ungraded staff may be expected, non-personnel costs will increase, including contracts for hardware and software maintenance, new supply items, and more telephone and travelltraining expenses. The increased costs are justified by gaining universal access to an improved catalog database.
Function, clinical application, and strategies of Pre-mRNA splicing in cancer (2018)

Pre-mRNA splicing is a fundamental process that plays a considerable role in generating protein diversity. Pre-mRNA splicing is also the key to the pathology of numerous diseases, especially cancers. In this review, we discuss how aberrant splicing isoforms precisely regulate three basic functional aspects in cancer: proliferation, metastasis and apoptosis. Importantly, clinical function of aberrant splicing isoforms is also discussed, in particular concerning drug resistance and radiosensitivity. Furthermore, this review discusses emerging strategies how to modulate pathologic aberrant splicing isoforms, which are attractive, novel therapeutic agents in cancer. Last we outline current and future directions of isoforms diagnostic methodologies reported so far in cancer. Thus, it is highlighting significance of aberrant splicing isoforms as markers for cancer and as targets for cancer therapy.
Electrical Conduction of Regioregular and Regiorandom Poly(3-hexylthiophene) Doped with Iodine (2005)

The electrical conduction of regioregular poly(3-hexylthiophene) (RR-P3HT) and regiorandom poly(3-hexylthiophene) (RRa-P3HT) doped with iodine is studied as a function of doping level. The electrical conductivity shows the thermally-activated behavior at low doping levels below 10% for RR-P3HT and 18% for RRa-P3HT. At high doping levels higher than 10% for RR-P3HT and 20% for RRa-P3HT, the electrical conductivity shows the three-dimensional variable-range hopping. The change in the conduction mechanism is explained qualitatively in terms of the growth of the density of states at the Fermi level and the dimensional crossover of the conduction path. The difference in the doping levels where the change occurs in RR-P3HT and RRa-P3HT is understood in terms of the carrier localization length, that is, the spatial extent of polaronic excitations in these polymers.

Thermal Intramolecular Electron Transfer in a Ferrocene-Naphthoquinone Linked Dyad Promoted by Metal Ions (2002)

Initiated by metal ions: Intramolecular electron transfer in a donor–acceptor linked system (a ferrocene–naphthoquinone dyad Fc–NQ; see scheme) can be started thermally by adding an appropriate metal ion (Sc3+) which can promote thermal electron transfer, which would otherwise be unlikely to occur, to give a radical ion complex (Fc+–NQ.−/Sc3+).

Self-expanding nitinol stents in canine vertebral arteries: hemodynamics and tissue response. (1995)

No significant risk of thromboembolic events exists after implanting these nitinol stents in nonatherosclerotic vertebral arteries in dogs. Thicker neointimal growth after stenting may result from either low wall shear stress with possible flow separation or from changes in the shape and size of the stent, or both.

Development of a Silicon Two-Axis Micromirror for an Optical Cross-Connect (2000)

This paper describes the development of a two-axis silicon micromirror for a 480 x 480 optical cross-connect (OXC). The micromirror is an electromagnetically actuated, analog silicon mirror. The range of motion for the micromirror is 8 . Full range of motion open-loop moves have been demonstrated in under 5 ms, which enables a full 480 x480 switch reconfiguration in 10 ms. The micromirror and OXC have been optimized for low loss. The average optical insertion loss is -2.5 db at 1550 nm and -2.9 db at 1310 nm, the two primary wavelengths in fiber optic data transmission. SONET data at 2.4 Obits/sec has been transmitted through the OXC with no loss penalty.
A 78 dB dynamic range, 0.27 dB accuracy, single-stage RF-PGA using thermometer-weighted and binary-weighted transconductors for SAW-less WCDMA/LTE transmitters (2010)

A single-stage RF programmable gain amplifier (RF-PGA) in 65-nm CMOS is presented. The RF-PGA consists of thermometer-weighted transconductors and binary-weighted transconductors with an R-2R ladder. The transmitter prototype with the single-stage RF-PGA achieves 78 dB dynamic range, 0.27 dB accuracy in 1dB step at 1950 MHz. The measured transmitter noise in RX band is -160.4 dBc/Hz. The ACLR and EVM with LTE modulated signal (BW=20 MHz) are -40 dBc and 3.4%, respectively.
Generating instruction streams using abstract CSP (2012)

One of the challenges that processor level stimuli generators are facing is the need to generate stimuli that exercise microarchitectural mechanisms deep inside the verified processor. These scenarios require specific relations between the instructions participating in them. We present a new approach for processor-level scenario generation. The approach is based on creating an abstract constraint satisfaction problem, which captures the essence of the requested scenario. The generation of stimuli is done by interleaving between progress in the solution of the abstract CSP and generation of instructions. Compared with existing solutions of scenario generation, this approach yields improved coverage and reduced generation fail rate.

Advanced optimization and process control of plasma doping apparatus (2008)

Abstract In keeping with the trend of progressively shrinking device features, future generation advanced Logic and DRAM devices will require shallower junction depths and poly thickness and also higher doses compared to their current day counterparts. Present monomer based beamline technology suffers decreasing throughput during this transition as a result of space charge limitations. Plasma doping is a well characterized alternative that not only meets the doping requirements for &lt;70 nm ITRS DRAM and Logic technology nodes but also features superior throughput levels that are largely energy insensitive. The simplicity of the Plasma doping tool design and evolution in process control offer a promising future for production worthiness of this technique. Key challenges for adoption of plasma doping tools in mainstream doping production are dose and contamination control. In this article, we report on the plasma modeling and diagnostic approaches used to optimize reactor design and describe how a closed loop faraday dose monitoring system is utilized to ensure dose repeatability. This combined modeling, diagnostics and sensor approach, which will be validated with on‐wafer measurements, enables the adoption of plasma doping in a mass production environment.

Combustor and Material Integration for high speed aircraft in the European research Program ATLLAS2 (2014)

Hypersonic airliner would be exposed to temperatures that are beyond the limits of classical aircraft materials. In order to handle this problem the latest developments of new materials and composite structures suitable for high temperature application need to be taken into account. The focus of the European Research program ATLLAS is on advanced light-weight, high-temperature material development strongly linked to a high-speed passenger aircraft design. ATLLAS stands for Aerodynamic and Thermal Load Interactions with Lightweight Advanced Materials for High Speed Flight. The 4 years program ATLLAS-II is a logical continuation project built upon the experience and technology development gained within ATLLAS-I. The corresponding work related to combustor structures and material integration deals with the opportunity to investigate at academic level, both in basic and relevant environment, different solutions possibly usable to ensure the long range cruise of a high speed airliner. Different materials (UTHC, CMC, metallic) and different cooling techniques (radiation, convective, transpiration) are studied. Available numerical or semi-empirical tools are used to prepare the test, to design the different architectures. A pin fin experiment allows to better know the pressure drop and the heat transfer for different channel patterns with thermal cristal techniques. The ERBURIG-K long duration test facility allow to characterize different ceramic matrix composite uncooled samples and will allow to realize, at small scale, a long duration (several hours) investigation of cooled ceramic structure in PTAH-SOCAR technology. A multifonctionnal metallic transpiration cooled HSS panel using Hollow Spheres Stacking as core material was designed and preliminary tested in cold conditions with GN2 and in hot conditions with infra lamps under 1 MW/m² heat flux. CMC and UHTC materials are used to design, manufacture and test generic fin injectors usable in high speed combustors. Industrial hypersonic METHYLE test facility is used to test in relevant Mach 6 combustor environment HSS panel as well as advanced fin injectors. Hot and cold permeability of composites is documented with GN2 and GH2. Numerical models are used in accordance with the experiments, some examples are given in the present paper.
Phylodynamic signatures in the emergence of community-associated MRSA (2022)

Community-associated, methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) lineages have emerged in many geographically distinct regions around the world during the past 30 y. Here, we apply consistent phylodynamic methods across multiple community-associated MRSA lineages to describe and contrast their patterns of emergence and dissemination. We generated whole-genome sequencing data for the Australian sequence type (ST) ST93-MRSA-IV from remote communities in Far North Queensland and Papua New Guinea, and the Bengal Bay ST772-MRSA-V clone from metropolitan communities in Pakistan. Increases in the effective reproduction number (R<sub>e</sub>) and sustained transmission (R<sub>e</sub> > 1) coincided with spread of progenitor methicillin-susceptible <i>S. aureus</i> (MSSA) in remote northern Australian populations, dissemination of the ST93-MRSA-IV genotype into population centers on the Australian East Coast, and subsequent importation into the highlands of Papua New Guinea and Far North Queensland. Applying the same phylodynamic methods to existing lineage datasets, we identified common signatures of epidemic growth in the emergence and epidemiological trajectory of community-associated <i>S. aureus</i> lineages from America, Asia, Australasia, and Europe. Surges in R<sub>e</sub> were observed at the divergence of antibiotic-resistant strains, coinciding with their establishment in regional population centers. Epidemic growth was also observed among drug-resistant MSSA clades in Africa and northern Australia. Our data suggest that the emergence of community-associated MRSA in the late 20th century was driven by a combination of antibiotic-resistant genotypes and host epidemiology, leading to abrupt changes in lineage-wide transmission dynamics and sustained transmission in regional population centers.
Air flow at different temperatures increases sodium lauryl sulphate-induced barrier disruption and irritation in vivo (2005)

Warm air flow has an additional effect on the SLS-induced barrier disruption in a tandem irritation test with sequential exposure to SLS/air flow. This combination is suspected to promote ICD in workplace and household situations, especially in short-term applications as tested in our model.
Comparative study on neutronics characteristics of a 1500 MWe metal fuel sodium-cooled fast reactor (2017)

Under the cooperative effort of the Civil Nuclear Energy R&D Working Group within the framework of the U.S.-Japan bilateral, Argonne National Laboratory (ANL) and Japan Atomic Energy Agency (JAEA) have been performing benchmark study using the Japan Sodium-cooled Fast Reactor (JSFR) design with metal fuel. In this benchmark study, core characteristic parameters at the beginning of cycle were evaluated by the best estimate deterministic and stochastic methodologies of ANL and JAEA. The results obtained by both institutions show a good agreement with less than 200 pcm of discrepancy in the neutron multiplication factor, and less than 3% of discrepancy in the sodium void reactivity, Doppler reactivity, and control rod worth. The results by the stochastic and deterministic approaches were compared in each party to investigate impacts of the deterministic approximation and to understand potential variations in the results due to different calculation methodologies employed. From the detailed analysis of methodologies, it was found that the good agreement in the multiplication factor from the deterministic calculations comes from the cancellation of the differences in the methodology (0.4%) and nuclear data (0.6%). The different treatment in reflector cross section generation was estimated as the major cause of the discrepancy between the multiplication factors by the JAEA and ANL deterministic methodologies. Impacts of the nuclear data libraries were also investigated using a sensitivity analysis methodology. The differences in the inelastic scattering cross sections of U-238, ν values and fission cross sections of Pu-239 and μ-average of Na-23 are the major contributors to the difference in the multiplication factors.
