A comprehensive modeling of the hybrid temperature electric swing adsorption process for CO2 capture (2018)

Adsorption technologies provide high selectivity and low energy consumption making this technique very attractive to be employed in post-combustion carbon capture. In this publication, a material made of activated carbon and zeolite 13X is considered for a hybrid process termed Temperature Electric Swing Adsorption (T/ESA). This hybrid T/ESA can work as a traditional Temperature Swing Adsorption (TSA) heated by hot gas, but can also increase the temperature of the adsorbent very fast by Joule effect as long as the activated carbon provides a continuous conductive matrix for electricity. This paper discusses a detailed modeling of the T/ESA process when applied to three cases. The first case is the simulation of the T/ESA process with exhaust with 12% of CO2 concentration, which has been chosen to validate the model against literature results. The second and third case studies consider the T/ESA application in a natural gas combined cycle (NGCC) traditional power plant, and in a NGCC plant with exhaust gas recycle (EGR). These cases were selected to investigate the adsorption technology at low CO2 concentration and quantify the benefit of the EGR for carbon capture applications. Starting from an NGCC overall electric efficiency of 58.3% LHV based, the efficiency of the NGCC with T/ESA technology reduces to 35.3% while with EGR is 38.9% against the 49.9% with the MEA absorption plant. The same results are confirmed by the SPECCA index 13.05 MJLHV/kgCO2 to 9.64 MJLHV/kgCO2 against the reference of 3.36 MJLHV/kgCO2. The energy penalty of the T/ESA is significant because of electric consumptions required for the heating and fast cooling of the adsorbent.
Manufacturability Aware Design. (2007)

The aim of this work is to provide solutions that optimize the tradeoffs among design, manufacturability, and cost of ownership posed by technology scaling and sub-wavelength lithography. These solutions may take the form of robust circuit designs, cost-effective resolution technologies, accurate modeling considering process variations, and design rules assessment. We first establish a framework for assessing the impact of process variation on circuit performance, product value and return on investment on alternative processes. Key features include comprehensive modeling and different handling on die-to-die and within-die variation, accurate models of correlations of variation, realistic and quantified projection to future process nodes, and performance sensitivity analysis to improved control of individual device parameter and variation sources. Then we describe a novel minimum cost of correction methodology which determines the level of correction of each layout feature such that the prescribed parametric yield is attained with minimum RET (Resolution Enhancement Technology) cost. This timing driven OPC (Optical Proximity Correction) insertion flow uses a mathematical programming based slack budgeting algorithm to determine OPC level for all polysilicon gate geometries. Designs adopting this methodology show up to 20% MEBES (Manufacturing Electron Beam Exposure System) data volume reduction and 39% OPC runtime improvement. When the systematic correction residual errors become unavoidable, we analyze their impact on a state-of-art microprocessor's speedpath skew. A platform is created for diagnosing and improving OPC quality on gates with specific functionality such as critical gates or matching transistors. Significant changes in full-chip timing analysis indicate the necessity of a post-OPC performance verification design flow. Finally, we quantify the performance, manufacturability and mask cost impact of globally applying several common restrictive design rules. Novel approaches such as locally adapting FDRs (flexible design rules) based on image parameters range, and DRC Plus (preferred design rule enforcement with 2D pattern matching) are also described.
Microimaging FTIR of head and neck tumors. IV (2008)

On continuing our studies on head and neck neoplasia, specimens from salivary gland tumors have been explored by using infrared microimaging spectroscopy to discern healthy from neoplastic tissues. Samples with Warthin tumor, epithelial displasia, marginal B-cell lymphoma, low-grade adenocarcinoma, and adenoid cystic carcinoma pathologies have been investigated by using conventional light sources. Changes were monitored at the molecular level, probing spectral markers such as Amide I and II, phosphate, nucleic acids, and carbohydrates vibrational modes. In all cases, supervised and unsupervised spectral analyses resulted in satisfactory agreement with histopathological findings.
The First Catalytic Asymmetric Allylation of Imines with the Tetraallylsilane−TBAF−MeOH System, Using the Chiral Bis-π-allylpalladium Complex (2004)

The asymmetric allylation of imines with use of catalytic transition metals with chiral ligands should be a new frontier of the enantioselective C-C bond formation. So far allyltrimethylsilane, allyltrichlorosilane, and allyltrimethoxysilane have been commonly employed with use of either silane activators or dual silane-imine activators. However, tetraallylsilane is untouched in the allylation of aldimines. The first allylation of aldimines with the tetraallylsilane-TBAF-MeOH system with use of the bis-pi-allylpalladium catalyst under catalytic, non-Lewis acid, essentially neutral and very mild reaction conditions has been achieved. The reaction is triggered by dual activation/promotion by TBAF and MeOH in which the fluoride anion activates the C-Si bond cleavage and MeOH promotes the facile protonation of intermediate palladium amide. Thus, the synthesis of chiral homoallylamines is achieved in a shorter reaction time and higher yields and enantioselectivities through an efficient, general, and reproducible allylation protocol for imines.
Hsp70 Binding to the N-terminal Domain of Hsp104 Regulates [PSI+] Curing by Hsp104 Overexpression (2023)

Hsp104 propagates the yeast prion [<i>PSI<sup>+</sup></i>], the infectious form of Sup35, by severing the prion seeds, but when Hsp104 is overexpressed, it cures [<i>PSI<sup>+</sup></i>] in a process that is not yet understood but may be caused by trimming, which removes monomers from the ends of the amyloid fibers. This curing was shown to depend on both the N-terminal domain of Hsp104 and the expression level of various members of the Hsp70 family, which raises the question as to whether these effects of Hsp70 are due to it binding to the Hsp70 binding site that was identified in the N-terminal domain of Hsp104, a site not involved in prion propagation. Investigating this question, we now find, first, that mutating this site prevents both the curing of [<i>PSI<sup>+</sup></i>] by Hsp104 overexpression and the trimming activity of Hsp104. Second, we find that depending on the specific member of the Hsp70 family binding to the N-terminal domain of Hsp104, both trimming and the curing caused by Hsp104 overexpression are either increased or decreased in parallel. Therefore, the binding of Hsp70 to the N-terminal domain of Hsp104 regulates both the rate of [<i>PSI<sup>+</sup></i>] trimming by Hsp104 and the rate of [<i>PSI<sup>+</sup></i>] curing by Hsp104 overexpression.
Implementing transmission zeros in inductive-window bandpass filters (1995)

Transmission zeros are usually implemented in microwave filters as extracted poles, or with cross couplings between nonadjacent cavities. Recent work, however, indicates that, for inductive band-pass filters, higher order-mode excitation can be usefully exploited for the purpose of creating transmission zeros. In this paper we describe a new cavity configuration that can be used to introduce transmission zeros in the electrical performance of microwave filters based on thick inductive windows in rectangular waveguides using the higher order-mode interactions. One transmission zero per filter cavity can be introduced and its frequency location can be easily controlled adjusting suitable geometrical parameters. The basic principle is discussed in detail and a computer aided design procedure is also presented. Finally, several application examples are included indicating how the new cavity design can indeed be used to improve the performance of this class of filters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Imaging the Addicted Human Brain (2007)

Modern imaging techniques enable researchers to observe drug actions and consequences as they occur and persist in the brains of abusing and addicted individuals. This article presents the five most commonly used techniques, explains how each produces images, and describes how researchers interpret them. The authors give examples of key findings illustrating how each technique has extended and deepened our knowledge of the neurobiological bases of drug abuse and addiction, and they address potential clinical and therapeutic applications.
Substituent-Induced Circular Dichroism in Phthalocyanines (1999)

Phthalocyanines with two and four optically active binaphthyl units have been synthesized and characterized by electronic absorption, CD, and MCD spectroscopy. The chiral substituents induce CD in the in-plane polarized Q and Soret bands of phthalocyanines: phthalocyanines having R and S binaphthyls show positive and negative CD, respectively. The geometries of the compounds were optimized at the PM3 level, and a vector coupling model for the induction of rotatory strength was developed. This model provides a semi-quantitative description of the CD spectra. Thus, not only the sign of the CD spectra but also the intensity relationship between the Soret and Q CD bands and, further, the shape of the Q CD band were reasonably explained. The discussion focuses on the important role of the central hydrogen atoms.

Recommended methods for an additional red cell enzyme (pyrimidine 5′-nucleotidase) assay and the determination of red cell adenosine-5′-triphosphate, 2,3-diphosphoglycerate and reduced glutathione (1989)

In 1977 the Red Cell Enzyme Expert Panel of the International Committee for Standardization in Haematology (ICSH) issued recommended methods for red cell enzyme analysis These methods have made it possible to measure red cell enzyme activity with reliable and convenient techniques, and to compare results obtained in different laboratories. After the publication of the ICSH recommended methods, pyrimidine 5'-nucleotidase (P5N) deficiency came to our attention. This enzyme was first described by Hereditary deficiency results in nonspherocytic haemolytic anaemia. This syndrome is characterized by haemolytic anaemia, pronounced basophilic stippling of red cells, and marked increase in both red cell reduced glutathione (GSH) and pyrimidine-containing nucleotides. To date, more than 40 cases have been reported P5N deficiency appears to be one of the more common causes of hereditary nonspherocytic haemolytic anaemia. It may also be important in the aetiology of the anaemia of lead intoxication because lead markedly inhibits P5N activity.
Antigen Localization Controls T Cell-Mediated Tumor Immunity (2011)

Effective antitumor immunotherapy requires the identification of suitable target Ags. Interestingly, many of the tumor Ags used in clinical trials are present in preparations of secreted tumor vesicles (exosomes). In this study, we compared T cell responses elicited by murine MCA101 fibrosarcoma tumors expressing a model Ag at different localizations within the tumor cell in association with secreted vesicles (exosomes), as a nonsecreted cell-associated protein, or as secreted soluble protein. Remarkably, we demonstrated that only the tumor-secreting vesicle-bound Ag elicited a strong Ag-specific CD8(+) T cell response, CD4(+) T cell help, Ag-specific Abs, and a decrease in the percentage of immunosuppressive regulatory T cells in the tumor. Moreover, in a therapeutic tumor model of cryoablation, only in tumors secreting vesicle-bound Ag could Ag-specific CD8(+) T cells still be detected up to 16 d after therapy. We concluded that the localization of an Ag within the tumor codetermines whether a robust immunostimulatory response is elicited. In vivo, vesicle-bound Ag clearly skews toward a more immunogenic phenotype, whereas soluble or cell-associated Ag expression cannot prevent or even delay outgrowth and results in tumor tolerance. This may explain why particular immunotherapies based on these vesicle-bound tumor Ags are potentially successful. Therefore, we conclude that this study may have significant implications in the discovery of new tumor Ags suitable for immunotherapy and that their location should be taken into account to ensure a strong antitumor immune response.
Catalytic properties of composite materials based on mesoporous silica and zirconium hydrogen phosphate (2014)

We have synthesized composite materials based on SBA-15 mesoporous silica and zirconium phosphate. The materials have been characterized by scanning electron microscopy, transmission electron microscopy, inductively coupled plasma mass spectrometry, X-ray diffraction, BET measurements, 31P NMR spectroscopy, and thermogravimetry, and have been employed as catalysts for ethanol dehydration. Even though their catalytic activity is somewhat lower than that of fine-particle zirconium phosphates with layered and framework structures, they offer an increased ethylene yield at low temperatures.
Sébastien Choulette (Toul 1803-Nice 1877), pharmacien militaire, professeur, bromatologiste, botaniste et géographe (2004)

Sébastien Choulette naît à Toul le 21 octobre 1803. À vingt ans, en 1823, il entame une carrière militaire en devenant pharmacien élève à l'hôpital militaire d'instruction de Metz. Au terme de plusieurs affectations, il est reçu pharmacien à Strasbourg le 26 janvier 1833. En 1841, il devient professeur « de botanique et de préparation des médicaments » à l'hôpital militaire d'instruction de Strasbourg où il reste affecté jusqu'en 1852 et où il rédige cinq ouvrages. À ce moment, il est désigné pour les hôpitaux de la division de Constantine, en Algérie, où il passe un peu moins de sept années. Ce séjour est pour lui l'occasion de publier au Répertoire de pharmacie huit notes sur des sujets pharmaceutiques, analytiques ou médico-légaux, plus tard réunies dans un ouvrage intitulé Observations pratiques de pharmacie, de chimie et de médecine légale, mais surtout de ras- sembler une très importante collection de plantes sèches diffusée sous le titre de Fragmenta florae Algeriensis exsiccata. Plusieurs espèces de plantes d'Algérie lui sont dédiées. Après avoir reçu la direction de la Réserve des médicaments de Marseille en 1858, Choulette se retire en 1864 à Nice où il meurt le 20 juillet 1877.
Micro-Fabricated Optics for Multiphoton Microscopy (2023)

We report new methods of 2 photon polymerization of microlenses with high numerical aperture, large diameter and good optical quality. We characterize the aberrations of these lenses that, coupled to raster scanning optical microscopes, allow two-photon excitation imaging of cells. In-vivo non-linear imaging will be also discussed, opening the possibility to use these micro-lenses in implants for the continuous inspection of biological dynamics in vivo.
Multi-armed recommendation bandits for selecting state machine policies for robotic systems (2013)

We investigate the problem of selecting a state-machine from a library to control a robot. We are particularly interested in this problem when evaluating such state machines on a particular robotics task is expensive. As a motivating example, we consider a problem where a simulated vacuuming robot must select a driving state machine well-suited for a particular (unknown) room layout. By borrowing concepts from collaborative filtering (recommender systems such as Netflix and Amazon.com), we present a multi-armed bandit formulation that incorporates recommendation techniques to efficiently select state machines for individual room layouts. We show that this formulation outperforms the individual approaches (recommendation, multi-armed bandits) as well as the baseline of selecting the `average best' state machine across all rooms.
Identification of a low-frequency elastic behaviour in liquid water (2012)

This article deals with the identification of solid-like properties measured at room temperature at a sub-millimetre length scale in liquid water. At a macroscopic scale, normal liquids (i.e. above melting temperature), and in particular water, are typically and empirically defined by the absence of shear elasticity, in contrast to solids or plastic fluids that require a stress threshold for flowing. A novel method optimizing the transmission of the shear stress to the sample enables a more complete probe of the mechanical response of liquids. It reveals that glass formers and viscous alkanes actually exhibit finite macroscopic shear elasticity away from any phase transition. This protocol is here applied for the first time to liquid water at room temperature, revealing, at the sub-millimetre scale, a low-frequency solid-like property.
Comparative Genomics and Transduction Potential of Enterococcus faecalis Temperate Bacteriophages (2009)

To determine the relative importance of temperate bacteriophage in the horizontal gene transfer of fitness and virulence determinants of Enterococcus faecalis, a panel of 47 bacteremia isolates were treated with the inducing agents mitomycin C, norfloxacin, and UV radiation. Thirty-four phages were purified from culture supernatants and discriminated using pulsed-field gel electrophoresis (PFGE) and restriction mapping. From these analyses the genomes of eight representative phages were pyrosequenced, revealing four distinct groups of phages. Three groups of phages, PhiFL1 to 3, were found to be sequence related, with PhiFL1A to C and PhiFL2A and B sharing the greatest identity (87 to 88%), while PhiFL3A and B share 37 to 41% identity with PhiFL1 and 2. PhiFL4A shares 3 to 12% identity with the phages PhiFL1 to 3. The PhiFL3A and B phages possess a high DNA sequence identity with the morphogenesis and lysis modules of Lactococcus lactis subsp. cremoris prophages. Homologs of the Streptococcus mitis platelet binding phage tail proteins, PblA and PblB, are encoded on each sequenced E. faecalis phage. Few other phage genes encoding potential virulence functions were identified, and there was little evidence of carriage of lysogenic conversion genes distal to endolysin, as has been observed with genomes of many temperate phages from the opportunist pathogens Staphylococcus aureus and Streptococcus pyogenes. E. faecalis JH2-2 lysogens were generated using the eight phages, and these were examined for their relative fitness in Galleria mellonella. Several lysogens exhibited different effects upon survival of G. mellonella compared to their isogenic parent. The eight phages were tested for their ability to package host DNA, and three were shown to be very effective for generalized transduction of naive host cells of the laboratory strains OG1RF and JH2-2.

Microbial uptake of uranium, cesium, and radium (1980)

The ability of diverse microbial species to concentrate uranium, cesium, and radium was examined. Saccharomyces cerevisiae, Pseudomonas aeruginosa, and a mixed culture of denitrifying bacteria accumulated uranium to 10 to 15% of the dry cell weight. Only a fraction of the cells in a given population had visible uranium deposits in electron micrographs. While metabolism was not required for uranium uptake, mechanistic differences in the metal uptake process were indicated. Uranium accumulated slowly (hours) on the surface of S. cerevisiae and was subject to environmental factors (i.e., temperature, pH, interfering cations and anions). In contrast, P. aeruginosa and the mixed culture of denitrifying bacteria accumulated uranium rapidly (minutes) as dense, apparently random, intracellular deposits. This very rapid accumulation has prevented us from determining whether the uptake rate during the transient between the initial and equilibrium distribution of uranium is affected by environmental conditions. However, the final equilibrium distributions are not affected by those conditions which affect uptake by S. cerevisiae. Cesium and radium were concentrated to a considerably lesser extent than uranium by the several microbial species tested. The potential utility of microorganisms for the removal and concentration of these metals from nuclear processing wastes and several bioreactor designs for contacting microorganisms with contaminated waste streams will be discussed.
Miniaturized low-loss millimeter-wave rat-race balun in a CMOS 28 nm technology (2011)

This paper presents the design of an integrated rat-race coupler for balun applications based on high quality factor Slow-wave CoPlanar Waveguides (S-CPW) transmission lines in millimeter wave frequencies. The 28 nm CMOS advanced digital technology by STMicroelectronics is used. The design procedure is detailed. Phase-inverter and optimized criteria for the transmission lines characteristics are used to minimize insertion losses and surface on the die. A 3D full wave EM software coupled to a circuit simulator is used to optimize the various building blocs. The compact and low-loss rat-race coupler shows state-of-art very exciting and promising performances. It occupies a 0.086 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> area. From 52 GHz till 67 GHz, return loss is better than 15 dB, while coupling factors are identical, varying between -4.2 and -4.4 dB, that means 1.4 dB maximal insertion loss. Finally between 13 and 85.5 GHz, the phase difference is kept constant, equal to 180°±1° while the isolation is better than 44 dB.
Optical and Magnetic Field Studies of the Lowest Triplet State of the Pyrazine Crystal (1970)

The electronic absorption spectrum of pyrazine crystals has been studied using single crystals at 4.2°K and polarized light. The origin shows three lines that are interpreted as (i) a B3u+, k = 0, factor group state at 26247.6 cm−1, (ii) two lines at 26254.7 and 26253.4 cm−1 corresponding to a split B2u−, k = 0, factor group state. These interpretations are made on the basis of high-field Zeeman effect studies. A low-field Zeeman study has revealed the ordering of magnetic substates in each factor group level at Tc &amp;lt; Tb &amp;lt; Ta. This yields the order Ty &amp;lt; Tz &amp;lt; Tx for the free molecule. The zero-field splitting is approximately + 0.3 cm−1 (D = − 32Y). A discussion of the relationship between such spin-state ordering and the electronic structure of pyrazine in a n3+π4*(nπbb) state is also presented.
