Poétiques de l’altérité : lecture croisée de J.-H. Rosny aîné et Stanley G. Weinbaum
No full textCet article propose une lecture croisée de deux œuvres « pionnières » dans le domaine de la science-fiction : Les Navigateurs de l’infini de J. H. Rosny aîné, publiés en 1925 et A Martian Odyssey de Stanley G. Weinbaum, paru en 1934. Malgré leur appartenance à des champs littéraires hétérogènes et un positionnement institutionnel très différent, ces deux auteurs ont eu le même souci d’écrire des textes conjecturaux exigeants, à la fois plausibles sur le plan scientifique et susceptibles de créer un mouvement de réflexion chez le lecteur. Ils tentent, par ailleurs, l’un et l’autre de créer un monde totalement autre, en refusant les facilités d’un imaginaire de simple « reduplication », tel qu’on pouvait le trouver chez des auteurs antérieurs ou contemporains, comme Edgar Rice Burroughs ou Gustave Le Rouge, tous deux auteurs de récits d’aventures se déroulant sur Mars. Une autre singularité des deux auteurs est de défendre une vision positive de l’Alien, qui se démarque de toute une tradition héritée de The War of the Worlds de H. G. Wells. Ces similitudes nous semblent justifier une démarche comparative, dont l’un des enjeux sera de proposer quelques éléments de réflexion sur l’histoire parallèle de la science-fiction américaine et de ce qu’il est convenu d’appeler la « science-fiction » française avant 1945. Au cours de notre lecture, nous serons amenés à nous interroger sur la cohérence des mondes imaginés par les deux auteurs et le principe de leur fonctionnement. Nous analyserons par ailleurs la façon dont ils abordent la question, cruciale dans la science-fiction moderne, de la communication avec des êtres « autres ». Nous tenterons, enfin, de préciser l’horizon idéologique de chacun des deux textes, qui s’inscrivent l’un et l’autre dans une perspective utopique.This essay presents a cross-reading of two seminal works in early Science Fiction : Les Navigateurs de l’Infini by J. H. Rosny aîné, a novel published in 1925 and A Martian Odyssey by Stanley G. Weinbaum, a short story published in 1934. In spite of many differences between the two authors, especially regarding their positions in the literary fields they belonged to, both of them had the same concern to write high-level conjectural texts, plausible from a scientific point of view and intellectually stimulating. They also attempted to create totally different worlds in the aforementioned works and refused plain reduplicative imagination, unlike many previous or contemporary Science Fiction writers, such as Edgar Rice Burroughs or Gustave Le Rouge, who had both set adventure stories on Mars, at the beginning of the 20th Century. Rosny and Weinbaum also had in common a positive view of the Aliens they described, which was at odds with the paradigm prevalent in Science Fiction since The War of the Worlds by H. G. Wells. All those commonalities justify a comparative approach. Our reading will aim at providing some elements of reflection about the parallel history of American Science Fiction and so-called French Science Fiction before 1945. In our reading, we will wonder how consistent the worlds created by Weinbaum and Rosny are and what structural principles underlie them. We will also analyze the way the two authors dealt with the question of communication with Aliens, which is pivotal to modern Science Fiction. At last, we will try to define the ideological backgrounds of those texts, which can be both read as utopias, a metaphysical one in Rosny’s novel and a political one in Weinbaum’s short story
Evaluation of the stromal vascular fraction of adipose tissue as the basis for a stem cell-based tissue-engineered vascular graft
No full textObjective: One of the rate-limiting barriers within the field of vascular tissue engineering is the lengthy fabrication time associated with expanding appropriate cell types in culture. One particularly attractive cell type for this purpose is the adipose-derived mesenchymal stem cell (AD-MSC), which is abundant and easily harvested from liposuction procedures. Even this cell type has its drawbacks, however, including the required culture period for expansion, which could pose risks of cellular transformation or contamination. Eliminating culture entirely would be ideal to avoid these concerns. In this study, we used the raw population of cells obtained after digestion of human liposuction aspirates, known as the stromal vascular fraction (SVF), as an abundant, culture-free cell source for tissue-engineered vascular grafts (TEVGs). Methods: SVF cells and donor-paired cultured AD-MSCs were first assessed for their abilities to differentiate into vascular smooth muscle cells (SMCs) after angiotensin II stimulation and to secrete factors (eg, conditioned media) that promote SMC migration. Next, both cell types were incorporated into TEVG scaffolds, implanted as an aortic graft in a Lewis rat model, and assessed for their patency and composition. Results: In general, the human SVF cells were able to perform the same functions as AD-MSCs isolated from the same donor by culture expansion. Specifically, cells within the SVF performed two important functions; namely, they were able to differentiate into SMCs (SVF calponin expression: 16.4% ± 7.7% vs AD-MSC: 19.9%% ± 1.7%) and could secrete promigratory factors (SVF migration rate relative to control: 3.1 ± 0.3 vs AD-MSC: 2.5 ± 0.5). The SVF cells were also capable of being seeded within biodegradable, elastomeric, porous scaffolds that, when implanted in vivo for 8 weeks, generated patent TEVGs (SVF: 83% patency vs AD-MSC: 100% patency) populated with primary vascular components (eg, SMCs, endothelial cells, collagen, and elastin). Conclusions: Human adipose tissue can be used as a culture-free cell source to create TEVGs, laying the groundwork for the rapid production of cell-seeded grafts
Dataset for the paper “Oujja, M., Palomar, T., Martínez-Weinbaum, M., Martínez-Ramírez S., Castillejo, M. 2021. Characterization of medieval-like glass alteration layers by laser spectroscopy and nonlinear optical microscopy. Eur. Phys. J. Plus 136, 859"
No full textThe study was undertaken in six medieval-like model glass samples UG (unaltered glass), MAK, MAR, MTA, MTB and MTN subjected to various environmental and atmospheric conditions in order to generate alteration layers of different characteristics. A potash-lime silicate glass, with composition similar to that of medieval glasses, was melted at 1400 °C during two hours, poured in a brass mould of rectangular cross section and annealed at 650 °C. The resulting glass ingot was cut in slices of around 10×10×2 mm3 and then polished using emery paper and an aqueous suspension of cerium oxide to obtain optical quality surfaces. Alteration of the glass slices was conducted by exposure to five different laboratory corrosion tests: SO2 corrosion for MAK sample, synthetic river water degradation for MAR, and degradation due to acid, basic and neutral medium for MTA, MTB and MTN, respectively.
This dataset consists of images of the samples; Laser-induced Breakdown Spectrocopy (LIBS) spectra; Laser-induced Fluorescence (LIF) spectra; Optical Microscopy (OM); FT-Raman spectroscopy and Multi-Photon Excitation Fluorescence (MPEF) signals obtained with a Nonlinear optical microscopy (NLOM). This information allows characterizing the composition of both body glass and determining the thickness of the degradation layer. Images are presented in JPG. All spectra are presented in cvs format, in a single page. Descriptions of the samples and the experimental conditions in which the spectra were taken and the name of the column values are included at the top of each page. For LIBS, 1 file per sample of elemental composition of the medieval-like glass are included. Each file is composed of 2 columns (wavelength and intensity). For LIF, 1 file per sample of the analysis of fluorescent species of each medieval-like glass are included. Each file is composed of 2 columns (wavelength and intensity). For NLOM, 2 files per sample. In the first one: “MPEF Safe limits”, each file is composed for 10 columns: 2 are for depth (µm) and 8 are for MPEF signal divided in two groups relating to the the power in the sample surface. In the second group of files: “MPEF profiles”, each file is composed for 4 columns: 1 is for depth (µm), 1 is the normalized MPEF intensity, 1 is the Lorentzian fit of depth (µm) and the last one Lorentzian fit. (The thicknesses of the degradation layers of the medieval-like glasses is calculated by the FWHM values of the fits after refractive index corrections). For FT-Raman, 1 file per sample of the analysis of the structure of the medieval-like glass through their vibrational modes is included. Each file is composed of 2 columns (Raman shift and intensity in arbitrary units).

Historical glass-based objects undergo, since the time of their manufacture, different degradation phenomena that are related to their composition and to the environment to which they were exposed. Three-dimensional (3D) structural and chemical characterization of the degradation layers is important to select the most adequate conservation strategies for glass objects. Optical microscopy (OM) is the most frequently used non-destructive method to examine the surface of historical glasses; however, the 3D structural assessment of alteration layers requires applying the destructive modality of this technique to conduct a cross-sectional study. In this work, a different approach for structural and compositional characterization of alteration layers on model medieval-like glasses is presented, based on the combination of the laser spectroscopies of laser-induced breakdown spectroscopy (LIBS), laser-induced fluorescence (LIF) and FT-Raman, and the emerging, cutting edge technique of nonlinear optical microscopy (NLOM) in the modality of multiphoton excitation fluorescence (MPEF). The
results obtained through this multi-analytical photonic approach were compared with those
retrieved by examination of the surface and cross sections of the samples by OM and scanning
electron microscopy–energy-dispersive X-ray spectroscopy (SEM–EDS). While the combination
of LIBS, LIF and FT-Raman served to assess the composition of the various alteration layers, the use of MPEF microscopy allowed the non-destructive determination of the thicknesses of these layers, showing for both thickness and composition a good agreement with the OM and SEM–EDS results. Thus, the proposed approach, which avoids sample preparation, illustrates the capability of non-destructive, or micro-destructive in the case of LIBS,

Sci., 12(11), 5760 (2022) (https://www.mdpi.com/2076-3417/12/11/5760). Flashed glasses are composed of a base glass and a thin colored layer and have been used since medieval times in stained glass windows. Their study can be challenging because of their complex composition and multilayer structure. In the present work, a set of optical and spectroscopic techniques have been used for the characterization of a representative set of flashed glasses commonly used in the manufacture of stained glass windows. The structural and chemical composition of the pieces were investigated by optical microscopy, field emission scanning electron microscopy-energy dispersive X-ray spectrometry (FESEM-EDS), UV-Vis-IR spectroscopy, laser-induced breakdown spectroscopy (LIBS), and laser-induced fluorescence (LIF). Optical microscopy and FESEM-EDS allowed the determination of the thicknesses of the colored layers, while LIBS, EDS, UV-Vis-IR, and LIF spectroscopies served for elemental, molecular, and chromophores characterization of the base glasses and colored layers. Results obtained using the micro-invasive LIBS technique were compared with those retrieved by the cross-sectional technique FESEM-EDS, which requires sample taking, and showed significant consistency and agreement. In addition, LIBS results revealed the presence of additional elements in the composition of flashed glasses that could not be detected by FESEM-EDS. The combination of UV-Vis-IR and LIF results allowed precise chemical identification of chromophores responsible for the flashed glass coloration.This research has been funded by the Spanish State Research Agency (AEI) through project PID2019-104124RB-I00/AEI/10.13039/501100011033, the Fundación General CSIC (ComFuturo Programme), by project TOP Heritage-CM (S2018/NMT-4372) from Community of Madrid, and by the H2020 European project IPERION HS (Integrated Platform for the European Research Infrastructure ON Heritage Science, GA 871034).There are 5 files which correspond to each technic employed for the analysis of the eleven different samples.

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
