Decomposition Algorithm of Laser Reflecting Waveform Based on Particle Swarm Optimization (2015)

The laser system's parameter fitting is an important step to the ranging and imaging, however, the complexity of the target object will cause the waveform superimposed, some existing algorithms are difficult to accurately obtain the parameters, by decomposing waveform into a series of continuous waveform can greatly improve the fitting accuracy.Considering the existing algorithm, LM algorithm's accuracy depends on the initial value and is easy to be caught in local optima, if the initial value is inaccurate then it is difficult to get an accurate fitting results.The laser we use is not the standard Gaussian model in reality,it is asymmetric,so if we directly use the value acquired by the Gaussian model,the result will be inaccurate.This paper will consider and propose a lidar waveform decomposition process based on the combination of the PSO algorithm and the LM algorithm in order to improve the final precision.
A DFT Quantum-Chemical Study of Ion-Pair Formation for the Catalyst Cp2ZrMe2 /MAO (2002)

A process of ion-pair formation in the system Cp2ZrMe2/methylaluminoxane (MAO) has been studied by means of density functional theory quantum-chemical calculations for MAOs with different structures and reactive sites. An interaction of Cp2ZrMe2 with a MAO of the composition (AlMeO)6 results in the formation of a stable molecular complex of the type Al5Me6O5Al(Me)O–Zr(Me)Cp2 with an equilibrium distance r(Zr–O) of 2.15 Å. The interaction of Cp2ZrMe2 with “true” MAO of the composition (Al8Me12O6) proceeds with a tri-coordinated aluminum atom in the active site (OAlMe2) and yields the strongly polarized molecular complex or the μ-Me-bridged contact ion pair (d) [Cp2(Me)Zr(μMe)Al≡MAO] with the distances r(Zr–μMe) = 2.38 Å and r(Al–μMe) = 2.28 Å. The following interaction of the μ-Me contact ion pair (d) with AlMe3 results in a formation of the trimethylaluminum (TMA)-separated ion pair (e) [Cp2Zr(μMe)2AlMe2]+–[MeMAO]– with r[Zr–(MeMAO)] equal to 4.58 Å. The calculated composition and structure of ion pairs (d) and (e) are consistent with the 13C NMR data for the species detected in the Cp2ZrMe2/MAO system. An interaction of the TMA-separated ion pair (e) with ethylene results in the substitution of AlMe3 by C2H4 in a cationic part of the ion pair (e), and the following ethylene insertion into the Zr–Me bond. This reaction leads to formation of ion pair (f) of the composition [Cp2ZrCH2CH2CH3]+–[Me-MAO]– named as the propyl-separated ion pair. Ion pair (f) exhibits distance r[Zr–(MeMAO)] = 3.88 Å and strong Cγ-agostic interaction of the propyl group with the Zr atom. We suppose this propyl-separated ion pair (f) to be an active center for olefin polymerization.
Online calculation of diesel engine torque dynamics (2014)

In current vehicles the actual value of engine torque is provided as interface signal to powertrain control units. For transient operation the dynamic behaviour of the combustion engine has to be estimated e.g. in the transmission control unit in order to coordinate the powertrain components. Due to the lack of provided data on the dynamic behaviour it needs to be modelled separately in each control unit, mainly map-based with high calibration effort. The engine control unit (ECU) has access to the relevant sensor and reference values for online calculation of diesel engine dynamics. Within this publication a model-based online torque calculation is proposed taking into account information that is already available in standard ECUs. Additionally the current torque reserve is computed. The calculation of characteristic parameters defining the dynamic behaviour for torque requests is outlined. Based on these signals prediction of engine dynamics is simplified and can significantly reduce the calibration effort e.g. in transmission control unit. The presented paper describes the calculation method and compares simulation results to engine test bed measurements for validation.
Differential phase optical coherence probe for depth-resolved detection of photothermal response in tissue (2003)

We describe a differential phase low-coherence interferometric probe for non-invasive, quantitative imaging of photothermal phenomena in biological materials. Our detection method utilizes principles of optical coherence tomography with differential phase measurement of interference fringe signals. A dual-channel optical low-coherence probe is used to analyse laser-induced thermoelastic and thermorefractive effects in tissue with micrometre axial resolution and nanometre sensitivity. We demonstrate an application of the technique using tissue phantoms and ex-vivo tissue specimens of rodent dorsal skin.

Quality improvements of ZnxCdyMg1−x−ySe layers grown on InP substrates by a thin ZnCdSe interfacial layer (1998)

The quality of lattice-matched ZnxCdyMg1−x−ySe epitaxial layers grown on (001) InP substrates with a III-V buffer layer has been improved by initially growing a ZnCdSe interfacial layer (50 Å) at low temperature. The widths of double crystal x-ray rocking curves for ZnxCdyMg1−x−ySe epilayers with band gaps as high as 3.05 eV were reduced to about 70 arcsec. The defect density evaluated from etch pit density and plan-view transmission electron microscopy measurements was reduced by two orders of magnitude, to 106–107 cm−2. The photoluminescence band edge emission became more symmetric and slightly narrower. It is proposed that an initial two-dimensional growth mode has been achieved by incorporating such a lattice-matched ZnCdSe layer.
Genetical Genomics Dissection of Cotton Fiber Quality (2008)

Cotton fiber is a commodity of key economic importance in both developed and developing countries. The two cultivated species, Gossypium hirsutum and G. barbadense , are tetraploid (2n=1x= 52 . 2.3 Gb). Cotton fibers are single-celled trichomes of the outermost epidermallayer of the ovule and elongate extensively to 25-50 mm. The final quality of the fiber results from complex developmentai processes and improvement of cotton fiber quality remains a challenge for many research groups worldwide. Although traditional breeding methods have proven efficient, the contribution of molecular genetics and genomic tools are gaining interest and the cotton fiber transcriptome has attracted a lot of attention in recent years. The major objective of the project (acronym Cotton_RILs) sponsored by the French National Research Agency (ANR) , is the genetic and genomic dissection of important fiber quality characteristics using a combination of classical QTL mapping and of gene expression QTL mapping. The integrated genetics and genomics approach (or genetical genomics approach) in this project is centered on a population of interspecific G. hirsutum X G. harhadense recombinant inbred lines (RILs) created by CIRAD. Specifie objectives are, 1. Construction of a saturated genetic map, 2. QTL mapping through multi-site phenotypic evaluation on 1 continents. 3. Population-wide gene expression analysis through microarray and cDNA-AFLP profilings and for 1 or 2 key developmental stages, and 4. Genetic fine mapping of selected QTLs using a large F, population. The 3 participants in the project. CIRAD (Montpellier, France) . Bayer Crop Science (Gent . Belgium). and CSIRü (Canberra , Australia) , have active research programs in applied genetics both through c1assical breeding and using modern biotechnology. Past achievements of the 3 laboratories are recognized worldwide and they are highly complementary in terms of their scientific expertise. Apart from greenhouses and biotechnology laboratories in their respective primary sites, they provide access to a broad range of field experimental sites on 4 continents, in Brazil and Cameroon through CIRAD partnerships and in the USA for Bayer CS.

Lipid Oxidation in Minced Herring (Clupea harengus) during Frozen Storage. Effect of Washing and Precooking (1998)

A 23 factorial experimental design was used to investigate the effect of washing in combination with precooking on the oxidative stability of lipids in minced herring (Clupea harengus) at −18 °C. The following variables were studied: washing (no, yes), cooking time (38, 54 min), and cooking temperature (55, 100 °C).The responses monitored were peroxide value (PV), absorbance at 234 nm (A234), absorbance at 268 nm (A268), and lipid soluble fluorescent products (FP). A partial least-squares regression analysis (PLS) revealed that the best lipid stability was obtained at minimum cooking time and at lower temperature. On the basis of compositional analyses and in vitro experiments, this finding was proposed to be due to heat inactivation of catalytic enzymes, without simultaneous activation, for example, of hemoproteins. Washing reduced these benefits from precooking by removal of pro-oxidative enzymes and also through a reduction in the amount of antioxidants as well as a relative increase in phospholipids and free fatty acids in the fat. Keywords: Clupea harengus; herring; lipid oxidation; washing; precooking
Study of planar-helix slow-Wave structure for application to travelling-wave tubes (1984)

A planar helix, constituted of a pair of unidirectionally conducting screens conducting in different directions, is suggested as a slow-wave structure for application in a travelling-wave tube (TWT). Circuit parameters, such as interaction impedance and space-charge parameter, are derived for the suggested planar-helix TWT. Computed results for the planar helix indicate a performance comparable with that of its circular helix counterpart. Also, the change in interaction impedance and the dispersion characteristics of the planar helix, are considered in the presence of dielectric substrates and a metal shield. Results are obtained for a few different possible configurations of the planar helix on dielectric substrates with or without a metal shield. The phase velocity and interaction impedance reduce, both as the substrate thickness increases and as the metal shields are brought closer to the planar helix. However, the resulting degradation in the characteristics of the structure with commonly used substrate materials, for example alumina and beryllia, is less severe than in the case of the circular helix.

Self-Healing Cements That Heal Without Dependence on Fluid Contact: A Laboratory Study (2010)

Summary Oilfield-cement compositions capable of self-healing cracks/fractures in set cement without depending on contact with a fluid, such as water or oil, are presented in this laboratory study. Traditionally, such compositions include additives that are capable of swelling when exposed to fluids such as water or oil, for example. Dependence on additives to swell and block flow channels after contact with a specific type of fluid hinders the self-healing effectiveness of the cement composition. As a result, designing cement compositions for field applications requires prior knowledge of the type of fluids that the cement may come into contact with, not only through the productive lifetime but also after abandonment of the well. Results from testing cement compositions containing a new class of elastomeric additives that do not depend on the nature of the fluid to seal cracks are presented in this paper. The elastomeric materials were chosen such that they have suitable chemical functionalities for binding strongly with cement and metal surfaces, and either have low melting points, as in the case of semicrystalline polymers, or have low glass transition temperatures (Tg), as in the case of amorphous polymers. Low viscosity or flowability of the elastomers at test temperature and the ability to bind to cement surfaces appear to be two key factors for their effectiveness. The test methods included static thermal healing, measurement of retained mechanical properties after self-healing, and fluid-flowrate measurements through cracked cement samples. The results show that the elastomers are effective in thermal healing of broken cement parts, in partial retention of mechanical properties, and in preventing fluid flow through failed cement samples.
Double crystal topographic investigations of PbTe grown by the travelling heater method (THM) (1984)

Abstract THM‐grown PbTe and PbTe: Tl were examined near the (n, —n)‐position by means of X‐ray double crystal arrangement. The half‐width of the rocking curves of Tl doped PbTe is larger than that of undoped PbTe by factor two. Long range and local lattice plane distortions, as well as disturbances induced during preparation, in the from of dislocation slip lines and greatly disoriented areas were observed.
Individual mobility by shared autonomous electric vehicle fleets: Cost and CO<inf>2</inf> comparison with internal combustion engine vehicles in Berlin, Germany (2017)

The current mobility paradigm is based on cheap fossil fuel energy, high CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> emissions and individual mobility. This paradigm faces economic, ecological and social limits. The aim of this paper is to analyse if a shared autonomous Electric Vehicles (EVs) fleet can meet these challenges and at the same time satisfy the current requirements of privately owned Internal Combustion Engine Vehicles (ICEVs). Therefore, analytical models have been developed to compute the fleet size and to simulate and investigate impacts on mobility behaviour in Berlin, Germany. The collected data were used to calculate cost effects, the energy consumption and the carbon footprint of different shared autonomous EVs in comparison with privately owned ICEVs. The approach shows that the system of a shared autonomous EV fleet could lower journey time, reduce CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> emissions, free up parking space in urban areas and generate cost benefits for customers.
Fabrication of YSZ Thin-Film for SOFC Applied by Electron Beam PVD (2006)

Thin film of yttria stabilized zirconia (YSZ) was prepared on alumina substrates by applying an electron beam physical vapor deposition (EB-PVD) method. The morphology and deposition behavior of the coating layer were investigated using atomic force microscope, secondary electron microscope, and X-ray diffractometer. The electrical conductivity of the YSZ coating layer was also evaluated. The fracture microstructure of YSZ electrolyte film, which was deposited with thickness of 10 μm, has showed a columnar structure. Also, the activation energy of the coating layer was similar to that of bulk YSZ.
Identical Gene Regulation Patterns of T3 and Selective Thyroid Hormone Receptor Modulator GC-1 (2011)

Synthetic selective thyroid hormone (TH) receptor (TR) modulators (STRM) exhibit beneficial effects on dyslipidemias in animals and humans and reduce obesity, fatty liver, and insulin resistance in preclinical animal models. STRM differ from native TH in preferential binding to the TRβ subtype vs. TRα, increased uptake into liver, and reduced uptake into other tissues. However, selective modulators of other nuclear receptors exhibit important gene-selective actions, which are attributed to differential effects on receptor conformation and dynamics and can have profound influences in animals and humans. Although there are suggestions that STRM may exhibit such gene-specific actions, the extent to which they are actually observed in vivo has not been explored. Here, we show that saturating concentrations of the main active form of TH, T(3), and the prototype STRM GC-1 induce identical gene sets in livers of euthyroid and hypothyroid mice and a human cultured hepatoma cell line that only expresses TRβ, HepG2. We find one case in which GC-1 exhibits a modest gene-specific reduction in potency vs. T(3), at angiopoietin-like factor 4 in HepG2. Investigation of the latter effect confirms that GC-1 acts through TRβ to directly induce this gene but this gene-selective activity is not related to unusual T(3)-response element sequence, unlike previously documented promoter-selective STRM actions. Our data suggest that T(3) and GC-1 exhibit almost identical gene regulation properties and that gene-selective actions of GC-1 and similar STRM will be subtle and rare.

Novel transcription regulatory elements inCaenorhabditis elegansmuscle genes (2004)

We report the identification of three new transcription regulatory elements that are associated with muscle gene expression in the nematode Caenorhabditis elegans. Starting from a subset of well-characterized nematode muscle genes, we identified conserved DNA motifs in the promoter regions using computational DNA pattern-recognition algorithms. These were considered to be putative muscle transcription regulatory motifs. Using the green-fluorescent protein (GFP) as a reporter, experiments were done to determine the biological activity of these motifs in driving muscle gene expression. Prediction accuracy of muscle expression based on the presence of these three motifs was encouraging; nine of 10 previously uncharacterized genes that were predicted to have muscle expression were shown to be expressed either specifically or selectively in the muscle tissues, whereas only one of the nine that scored low for these motifs expressed in muscle. Knockouts of putative regulatory elements in the promoter of the mlc-2 and unc-89 genes show that they significantly contribute to muscle expression and act in a synergistic manner. We find that these DNA motifs are also present in the muscle promoters of C. briggsae, indicating that they are functionally conserved in the nematodes.

Small Cell densification requirements in high capacity future cellular networks (2013)

In order to cope with the expected increase in traffic demand, the large-scale deployment of Small Cells (SC) becomes a cost-efficient way to realize the foreseen capacity explosion in the near future. In this paper we investigate, for a particular forecast in the 2020, what are the requirements in terms of capacity per area unit and how SC densification along with other design criteria can fulfill such demands. A wide set of illustrative numerical results are provided showing key design criteria such as frequency reuse, deployment planning, macro-cell power-down and transmitted power reduction, which, in conjunction with SC densification, have strong impact on the capacity delivered by the network.

Lymphoplasmacytic lymphoma involving the mediastinum and the lung, followed by amyloidosis: A surgically and genetically proven case (2020)

A 60-year-old man was admitted for ground glass opacity in the lower lung field and mediastinal lymphadenopathy. Blood tests revealed elevated serum IgM levels, and the urine test detected Bence-Jones protein. Surgical biopsy from the mediastinal lymph node and lung showed small lymphocytes and plasma cells between follicles, and AL kappa amyloid deposition. Genetic examination detected <i>MYD88</i> L265P mutation. Our diagnosis was lymphoplasmacytic lymphoma (LPL), involving the mediastinum and the lung, followed by amyloidosis. Mutation analysis, in addition to conventional histological evaluation, was useful for a precise diagnosis.
N° 10. — Influence d'un second composé métallique sur la polymérisation du chlorure de vinyle amorcée par le chlorure de tertiobutyle-magnésium (1970)

Dans la polymérisation du chlorure de vinyle amorcée par le chlorure de tertiobutyle-magnésium, l’addition de sels métalliques ou de leurs produits de réduction par l’organo- magnésien n’apporte pas d’amélioration sensible. Des effets de catalyse sont observés, principalement vis-à-vis des réactions secondaires entre le monomère et l’organomagnésien. Leur importance et leur sélectivité dépendent essentiellement de la nature du métal.
