Une lithographie singulière d’Emil Nolde pour le Faust Goethe
Authors: Stead Evanghelia 
Published: June 2019

L’article analyse la lithographie d’Emil Nolde Faust (1911), estampe autonome et singulière, qui renouvelle l’interprétation graphique du Faust de Goethe, assumée au xix e siècle par trois supports principaux (les séries gravées ou lithographiées inspirées de l’œuvre, les éditions monumentales ornées de la tragédie, et les livres illustrés et populaires à l’imagerie répétitive). La lithographie naît d’un dialogue des arts, notamment les mises en scène de Max Reinhardt, et diffère largement de l’aquarelle homonyme à laquelle elle est comparée. L’estampe correspond à une lecture synthétique de Faust I et de Faust II , à forte teneur mythique, artistique et symbolique, plus précisément, à une rune gravée dans la pierre, qui fait de Faust un grand poème primitif.
L’essence ou les sens d’un thème ? Étude de la femme combattante dans quelques nouvelles de Maupassant
Authors: Färnlöf Hans 
Published: June 2019

Cette étude examine la présentation de la femme combattante dans les nouvelles Boule de suif , Mademoiselle Fifi et Le Lit 29 . Malgré certaines ressemblances entre les protagonistes, celles-ci charrient des significations et des sens divers selon la mise en intrigue. En soulignant la fonctionnalité des éléments narratifs dans l’économie du récit court, cette étude propose une lecture alternative aux approches thématiques traditionnelles, qui s’efforcent plutôt d’attribuer une essence fixe au personnage-type. Par l’approche proposée, l’accent est mis sur le conteur Maupassant, notamment sur sa façon de construire des récits originaux dans lesquels il joue sur la transgression des valeurs établies tout en respectant le cadre référentiel au nom de la vraisemblance et en laissant au lecteur, par une « rhétorique du caché », le soin d’identifier lui-même les cibles de sa critique sociale.
Metallurgical knowledge transfer from Asia to Europe
Authors: Huang Chao 
Published: June 2019

The invention of paktong (白銅), literally “white copper”, was known in ancient China from at least the 4th century AD and is considered one of the most important inventions in the history of metallurgy, facilitating economic and material exchange in Europe during the 17-19th centuries. As recent investigations into the history of paktong show, it is generally recognised that the manufacturing of this metal had close associations with Southwest China. The acquisition of this metallurgical knowledge in Europe had very close relationship with Sweden and Austria. In this paper, the author will combine textual materials and field research findings to shed new light on the influence of paktong on 18-19th century Europe.
Un vaste chantier de collections
Authors: Antérion Dominique 
Published: June 2019

Grandement impactées par MétaLmorphoses, gigantesque chantier de restructuration de l’Hôtel de la Monnaie (Paris 6e), les collections historiques de la Monnaie de Paris ont vécu entre 2012 et 2018 des années difficiles ! Entre sécurisation, externalisation, obligation de récolement, création du nouveau musée et projet de nouveau médaillier ce sont au final plus de 140 000 objets qui ont été concernés par cette opération d’envergure. Néanmoins, les contraintes ont pu parfois devenir des opportunités. Outre le sens de l’adaptation des équipes, l’ouverture du nouveau musée du 11 Conti - Monnaie de Paris, l’implantation du nouveau médaillier, la poursuite du récolement décennal, témoignent de ce que l’on peut considérer comme l’un des plus vastes chantiers de collections menés en France ces dix dernières années.

Published: June 2019

AbstractEmerging 2D electronic materials have shown great potential for regulating and controlling optoelectronic processes. A 2D ferroelectric semiconductor coupled with the piezo‐phototronic effect may bring unprecedented functional characteristics. Here, a heterojunction photodetector made of p‐Si/V‐doped‐ferroelectric‐ZnO 2D nanosheets (FESZ‐PD) is fabricated, and the ferroelectricity‐enhanced piezo‐phototronic effect on the photoresponse behavior of the FESZ‐PD is carefully investigated. By introducing the ferroelectricity and the piezo‐phototronic effect, improved current rectification performance is achieved and the photoresponse performance of the heterojunction is enhanced in a broad spectral range. The applied voltage bias during measurement naturally causes ferroelectric spontaneous polarizations to align, resulting in a change in band structure near the interface and the local piezo‐phototronic effect. The modulated energy band promotes the generation, separation, and transportation efficiency of photogenerated carriers greatly. Compared with the Si/ZnO 2D nanosheets photodetector without ferroelectricity under strain‐free conditions, the photoresponsivity R of the FESZ‐PD increases by 2.4 times when applying a −0.20‰ compressive strain at +1 V forward bias. These results confirm the feasibility of coupling the ferroelectricity with the piezo‐phototronic effect in 2D ferroelectric materials to enhance the photoresponse behavior, which provides a good way to enable the development of high‐performance electronic and optoelectronic devices.
Strategy for the preparation of lightweight polypropylene/polyethylene‐octene elastomer composite foams with different phase morphologies using supercritical carbon dioxide
Authors: Wang Chaozhi , Wang Chao , Li Jiang 
Published: June 2019

ABSTRACTPolypropylene (PP)/polyethylene‐octene elastomer (POE) composites with a “sea‐island” structure and a cocontinuous structure were prepared. With the selection of a suitable foaming temperature, the supercritical carbon dioxide foaming of PP/POE composites with different phase morphologies occurred only in the POE phase. The effects of the POE content, foaming temperature, pressure, and number of layers on the cell size, cell density, apparent density, foaming layer density, and foaming ratio under different phase morphologies were investigated by scanning electron microscopy, polarized optical microscopy, differential scanning calorimetry, and dynamic thermomechanical analysis. This article provides a novel approach for foaming PP at a low temperature. For PP/POE‐blended composites with a “sea‐island” structure, the foaming temperature is as low as 80 °C, and for PP/POE alternating multilayered composites with a cocontinuous structure, foaming can occur at 40 °C. Compared with the conventional methods for foaming PP, this method avoids the problems of a high foaming temperature, a narrow range of the foaming temperature, and a low melt strength of the PP. Thus, the PP foaming method was successfully improved, yielding a new technique for the preparation of lightweight PP. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2019,136, 48157.
Structure variation and properties enhancement of uniaxial stretching poly(l‐lactic acid)/eggshell powder composites
Authors: Li Yi , Han Changyu , Yu Yancun , Huang Dexin 
Published: June 2019

ABSTRACTBiodegradable poly(l‐lactic acid) (PLLA)/eggshell (ES) powder composites were prepared by melt blending and uniaxial stretching above the glass‐transition temperature of PLLA. Scanning electron microscopy analyses revealed that micropores appeared in stretched composites. Porosity was affected by two factors, stretch ratios, and ES contents. Differential scanning calorimetry and wide‐angle X‐ray diffraction results demonstrated that strain‐induced crystallization in α‐form could be achieved in PLLA matrix. This superstructure improved multifunctional performance of PLLA composites. The exceptional combination of strength, modulus, and ductility of stretched PLLA90/ES10 composites with a stretch ratio of 6 were demonstrated, exceeding neat PLLA with the increments of 148, 190, and 507% in breaking strength, modulus, and elongation at break (140.8 MPa, 3810 MPa, and 35.2%), respectively. Meanwhile, the enhancement of thermomechanical properties due to high crystallinity and controllable degradation rates resulting from porosity were obtained by adjusting the composites compositions and/or stretch ratios. © 2019 Wiley Periodicals, Inc.

Published: June 2019

ABSTRACTTo achieve polymer‐matrix composites for sealing materials with thermostability and toughness, PTFE composites filled with short glass fibers (SGFs) were hyperthermal stretched to prepare a substrate material with high thermal stability and porosity. The effects of various tensile rates on the thermal and mechanical properties and morphologies were investigated. The results revealed that the thermal stability could be improved slightly and the thermal expansion coefficient of composites increased by the tensile rate. Through observing the morphologies, tensile process produced cavities and the increased tensile rate had negligible effects on porosity, which also could be proved by density test. From mechanical properties analysis, stretched composites exhibited that the tensile strength increases first and then decreases with the increased tensile rate. Although the variation tendency of Young's modulus is similar to that of tensile strength, which is smaller than that of unstretched composite. When the tensile rate reached 50 mm·min−1, the tensile strength and Young's modulus of the stretched composites increased by 65 and 9% to maximum, respectively. Meanwhile, elongation at break and shore hardness decreased. The thermal and mechanical properties improvement could be ascribed to the strain‐induced crystallization and crystal alignment. In addition, the interplanar spacing and grain size were inversely proportional to the tensile rate. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2019,136, 48175.

ABSTRACTIntussusception in lymphatic vessels has received less attention than in blood vessels. In tumors and pseudotumors of blood vessels with intravascular papillary structures, including sinusoidal hemangioma and intravascular papillary endothelial hyperplasia, we observed exuberant intussusceptive angiogenesis, as well as the similarity between papillae (term used by pathologists) and pillars/folds (hallmarks of intussusceptive angiogenesis). A similar response could be expected in lymphangiomas (lymphatic malformations and reactive processes rather than tumors) with papillae. The aim of this work is to assess whether papillae/pillars/folds and associated structures (vessel loops and septa) are present in lymphangiomas, and to establish the characteristics and formation of these structures. For this purpose, we selected lymphangiomas with intraluminal papillae (n = 18), including cystic, cavernous, circumscriptum, and progressive types, of which two cases of each type with a greater number of papillae were used for serial histologic sections and immunohistochemistry. The studies showed a) dilated lymphatic spaces giving rise to lymphatic–lymphatic vascular loops, which dissected and encircled perilymphatic structures (interstitial tissue structures/ITSs and pillars/posts), b) ITSs and pillars, surrounded by anti‐podoplanin‐positive endothelial cells, protruding into the lymphatic spaces (papillary aspect), and c) splitting, remodeling, linear arrangement, and fusion of papillae/pillars/folds, forming papillary networks and septa. In conclusion, as occurs in blood vessel diseases, the development of lymphatic vessel loops, papillae/pillars/folds, and septa (segmentation) supports intussusceptive lymphangiogenesis and suggests a piecemeal form of intussusception. This intussusceptive lymphangiogenesis in lymphatic diseases can provide a basis for further studies of lymphatic intussusception in other conditions, with clinical and therapeutic implications.

Published: June 2019

AbstractColorectal cancer (CRC) is the third most common cancer in all races worldwide in recent years. The survival of the CRC patients is mostly affected by the stage of the disease at the time of diagnosis. Thus, the current challenge is to find sensitive and reliable biomarkers in early screening of CRC. Recently, emerging evidence has shown that long non‐coding RNAs (lncRNAs) may play crucial roles in tumorigenesis. In this study, we found that lncRNA KIAA0125 was downregulated in colorectal tissues and cells. The functional study demonstrated that overexpression of KIAA0125 suppressed cell proliferation, migration, and invasion whereas the reversal effects were seen in silencing experiment. Besides, KIAA0125 inhibited epithelial–mesenchymal transition through Wnt/β‐catenin signaling in CRC. Our findings suggested that KIAA0125 may act as an oncosupressor gene and could be considered as a potential diagnosis biomarker in CRC.

Published: June 2019

AbstractPercutaneous coronary interventions with the Impella (Abiomed, MA) catheter‐based, micro‐axial mechanical left ventricular assist device is a safe option for patients undergoing higher risk interventions. However, severe peripheral arterial disease limits vascular access for Impella insertion. Upper extremity arterial access has been traditionally obtained under general anesthesia. We present the first case, to our knowledge, of using peripheral nerve blocks for Impella 3.5 CP insertion into the axillary artery.

AbstractSynthetic cannabinoids (SCs) remain one of the largest groups of new psychoactive substances (NPS) on the European drug market. Although the number of new derivatives occurring on the market has dropped in the last two years, newly emerging NPS still represent a challenge for laboratories performing forensic drug analysis in biological matrices. The newly emerged SC 4F‐MDMB‐BINACA has been reported by several law enforcement agencies in Europe and the USA since November 2018. This work aimed at revealing urinary markers to prove uptake of 4F‐MDMB‐BINACA and differentiate from the use of structurally similar SCs. Phase‐I metabolites detected in human urine specimens were confirmed by phase‐I metabolites generated in vitro using a pooled human liver microsomes (pHLM) assay. Seized materials and test‐purchased “legal high” products were analyzed by gas chromatography–mass spectrometry (GC–MS) and liquid chromatography−quadrupole‐time‐of‐flight−mass spectrometry (LC−qToF−MS). Human urine specimens and pHLM assay extracts were measured with liquid chromatography−electrospray ionization−tandem mass spectrometry (LC−ESI−MS/MS) and confirmed by LC−qToF−MS. In January 2019, the Institute of Legal Medicine in Erlangen (Germany) identified 4F‐MDMB‐BINACA in three herbal blends. During the same time period, the described SC was identified in a research chemical purchased online. Investigation of phase‐I metabolism led to the metabolites M10 (ester hydrolysis) and M11 (ester hydrolysis and dehydrogenation) as reliable urinary markers. Widespread distribution on the German drug market was proven by analysis of urine samples from abstinence control programs and by frequent detection of 4F‐MDMB‐BINACA in “herbal blends” and “‘research chemicals” purchased via the Internet.

AbstractBioelectrochemical systems (BES) are commonly utilized to generate green electricity, chemicals, and materials through bioelectrocatalytic processes. Over the years, the growing interests in low carbon energy, wastes valorization and the sustainable bioremediation of environmental pollutants have generated interests in BES such as microbial fuel cells (MFC) and bioelectrochemical fuel cells (BFC). The MFCs are the most advanced BES that can ensure the microbial conversion of chemical energy into electrical energy. Therefore, this article seeks to review and present valuable literature on the fundamental operational principles, mechanisms and understanding of BES such as MFCs. It seeks to highlight the schematics of these systems along with the processes and mechanisms such as the oxidation of organic substrates ranging from acetate compounds to complex mixtures. Furthermore, the prospects, challenges, and future applications of BES technologies are presented. The findings indicate that BFCs and MFCs are hampered by low efficiencies, energy output, mass transfer, porosity, and proton conductivity of the electrode and membrane materials along with mechanical strength, scalability, biocompatibility, and chemical stability. However, BES could potentially impact on clean energy production, greenhouse gases mitigation, wastewater treatment, bioanalysis, biosensors, and environmental remediation in the future.
Volatility forecasts using stochastic volatility models with nonlinear leverage effects
Authors: McAlinn Kenichiro , Ushio Asahi , Nakatsuma Teruo 
Published: June 2019

AbstractThe leverage effect—the correlation between an asset's return and its volatility—has played a key role in forecasting and understanding volatility and risk. While it is a long standing consensus that leverage effects exist and improve forecasts, empirical evidence puzzlingly does not show that this effect exists for many individual stocks, mischaracterizing risk, and therefore leading to poor predictive performance. We examine this puzzle, with the goal to improve density forecasts, by relaxing the assumption of linearity of the leverage effect. Nonlinear generalizations of the leverage effect are proposed within the Bayesian stochastic volatility framework in order to capture flexible leverage structures. Efficient Bayesian sequential computation is developed and implemented to estimate this effect in a practical, on‐line manner. Examining 615 stocks that comprise the S&P500 and Nikkei 225, we find that our proposed nonlinear leverage effect model improves predictive performances for 89% of all stocks compared to the conventional stochastic volatility model.

AbstractImaging studies have characterized functional and structural brain abnormalities in adults after premature birth, but these investigations have mostly used univariate methods that do not account for hypothesized interdependencies between brain regions or quantify accuracy in identifying individuals. To overcome these limitations, we used multivariate machine learning to identify gray matter volume (GMV) and amplitude of low frequency fluctuations (ALFF) brain patterns that best classify young adults born very preterm/very low birth weight (VP/VLBW; n = 94) from those born full‐term (FT; n = 92). We then compared the spatial maps of the structural and functional brain signatures and validated them by assessing associations with clinical birth history and basic cognitive variables. Premature birth could be predicted with a balanced accuracy of 80.7% using GMV and 77.4% using ALFF. GMV predictions were mediated by a pattern of subcortical and middle temporal reductions and volumetric increases of the lateral prefrontal, medial prefrontal, and superior temporal gyrus regions. ALFF predictions were characterized by a pattern including increases in the thalamus, pre‐ and post‐central gyri, and parietal lobes, in addition to decreases in the superior temporal gyri bilaterally. Decision scores from each classification, assessing the degree to which an individual was classified as a VP/VLBW case, were predicted by the number of days in neonatal hospitalization and birth weight. ALFF decision scores also contributed to the prediction of general IQ, which highlighted their potential clinical significance. Combined, the results clarified previous research and suggested that primary subcortical and temporal damage may be accompanied by disrupted neurodevelopment of the cortex.

Chronic alcohol consumption causes increased intestinal permeability and changes in the intestinal microbiota composition, which contribute to the development and progression of alcohol‐related liver disease. In this setting, little is known about commensal fungi in the gut. We studied the intestinal mycobiota in a cohort of patients with alcoholic hepatitis, patients with alcohol use disorder, and nonalcoholic controls using fungal‐specific internal transcribed spacer amplicon sequencing of fecal samples. We further measured serum anti–Saccharomyces cerevisiae antibodies (ASCA) as a systemic immune response to fungal products or fungi. Candida was the most abundant genus in the fecal mycobiota of the two alcohol groups, whereas genus Penicillium dominated the mycobiome of nonalcoholic controls. We observed a lower diversity in the alcohol groups compared with controls. Antibiotic or steroid treatment was not associated with a lower diversity. Patients with alcoholic hepatitis had significantly higher ASCA levels compared to patients with alcohol use disorder and to nonalcoholic controls. Within the alcoholic hepatitis cohort, patients with levels of at least 34 IU/mL had a significantly lower 90‐day survival (59%) compared with those with ASCA levels less than 34 IU/mL (80%) with an adjusted hazard ratio of 3.13 (95% CI, 1.11‐8.82; P = 0.031). Conclusion: Patients with alcohol‐associated liver disease have a lower fungal diversity with an overgrowth of Candida compared with controls. Higher serum ASCA was associated with increased mortality in patients with alcoholic hepatitis. Intestinal fungi may serve as a therapeutic target to improve survival, and ASCA may be useful to predict the outcome in patients with alcoholic hepatitis.
