Le château de Mugnano (Italie Centrale) au xiie siècle : révolution politique, évolution économique, stabilité naturelle
Authors: Dmitriev Nikita 
Published: December 2017

Le château de Mugnano, sur une colline du littoral du Tibre (province de Viterbe, région du Latium, Italie) est un habitat de la Tuscie romaine, région de l'État pontifical relativement pauvre en documentations, qui, à cause de son éloignement de Rome, du point de vue de l'organisation de la société, occupait la position intermédiaire entre le Latium, hautement féodalisé, et l'Ombrie, hors la juridiction temporaire pontificale au Haut Moyen-Âge, où les rapports féodo-vassaliques, avant la fin du xiie siècle, étaient extrêmement rares. Au cœur de l'évolution de cette région au xiie siècle se sont placées l'augmentation progressive des charges paysannes, la dépersonnalisation des liens entre eux et leur seigneur, ainsi que la scripturalisation du droit foncier, autrefois oral, au profit des seigneurs, dont la finalité était la dépossession des paysans. En s'appuyant sur les chartes privées du xe-xiiie siècles provenant de Mugnano, l'article s'efforce de reconstruire ces trois grandes lignes d’évolution : économique, sociale et politique.
Révolution de l’architecture domestique du Proche-Orient protobyzantin (iv-viie siècle) : culture de l’élite au détriment de la culture classique ?
Authors: Dumas Marius 
Published: December 2017

L’habitat urbain du Proche-Orient protobyzantin se distingue dans le domaine archéologique par une architecture domestique principalement monumentale. Le luxe et le caractère ostentatoire affichés des résidences, ont amené les archéologues à les assigner à une élite urbaine. L’état de conservation parfois surprenant des vestiges, a permis de relever de nombreuses caractéristiques susceptibles de qualifier chacune des époques, notamment lorsqu’il était possible de dresser une chronologie suffisamment précise pour isoler certaines transformations, au gré des réfections et des travaux qui se sont déroulés tout au long de la longue existence de ces demeures.Pendant la période protobyzantine, l’architecture domestique évolue, rompant avec son organisation initiale. En effet, les puissants n’hésitèrent pas à se confronter aux anciens plans de leurs demeures et à les repenser afin qu’ils correspondent davantage à de nouveaux besoins, stimulés par le fait d’amener dans la sphère privée des prérogatives initialement attachées à la sphère publique. Les transformations ont été jugées, tantôt en des termes de continuité ou d’évolution : tel le maintien de certaines composantes antiques au sein des phases les plus tardives ; tantôt en des termes plus dépréciatifs : synonymes de régression. En peu de mots de causer l’aliénation de l’héritage gréco-romain, quitte à négliger les éléments constitutifs de l’époque protobyzantine, qui fut même qualifiée de période de transition entre l’Antiquité et le Moyen-Age. Toutefois, il semble qu’aucun archéologue n’ait encore envisagé ces transformations en termes de révolution. Révolution au sens que les profondes mutations appartenant à l’Antiquité tardive imposaient de s’affranchir du carcan traditionnel imposé par la culture hellénistique, gréco-romaine et même indigène. Là, semble se terrer quelques innovations propres à cette période, terreau d’une véritable révolution : révolution des lieux du pouvoir, de son expression, tant dans son architecture que dans son exercice, à l’instar du développement des salles triconques dans les maisons attribuées aux « élites ».
A Note on Uniformly Bounded Cocycles into Finite Von Neumann Algebras
Authors: Boutonnet Remi , Roydor Jean 
Published: December 2017

AbstractWe give a short proof of a result of T. Bates and T. Giordano stating that any uniformly bounded Borel cocycle into a finite von Neumann algebra is cohomologous to a unitary cocycle. We also point out a separability issue in their proof. Our approach is based on the existence of a non-positive curvature metric on the positive cone of a finite von Neumann algebra.
Ring-theoretic blowing down. I
Authors: Rogalski Daniel , Sierra Susan J. , Stafford J. Toby 
Published: December 2017

One of the major open problems in noncommutative algebraic geometry is the classification of noncommutative projective surfaces (or, slightly more generally, of noetherian connected graded domains of Gelfand–Kirillov dimension 3). Earlier work of the authors classified the connected graded noetherian subalgebras of Sklyanin algebras using a noncommutative analogue of blowing up. In order to understand other algebras birational to a Sklyanin algebra, one also needs a notion of blowing down. This is achieved in this paper, where we give a noncommutative analogue of Castelnuovo’s classic theorem that (–1)-lines on a smooth surface can be contracted. The resulting noncommutative blown-down algebra has pleasant properties; in particular it is always noetherian and is smooth if the original noncommutative surface is smooth.
In a companion paper we will use this technique to construct explicit birational transformations between various noncommutative surfaces which contain an elliptic curve.

Lucrècia Borja. L'alteració d’una identitat i l’errònia atribució de la pintura de Flora de Bartolomeo Veneto
Authors: Vico Alexandre 
Published: December 2017

Resum: Aquest treball pretén emfatitzar l’errònia identitat que ha arribat fins als nostres dies de Lucrècia Borja i l’equivocada atribució que se n’ha fet d’alguns retrats. Com ara, la pintura de Flora (c.1520), pintada per Bartolomeo Veneto, que ha passat a la història com una indissoluble identificació de Lucrècia. Els estudis actuals han demostrat que representa un model ideal influït pel context literari probablement relacionat amb Pietro Bembo. Durant el Renaixement, els retrats representen molt més que una identitat concreta i mimètica. Són suports de prestigi i transmissió ideològica, de virtuts morals, memòria, etc. En l’àmbit artístic venecià de principis del segle XVI sorgeixen múltiples retrats femenins de difícil identificació que la crítica freqüentment ha relacionat amb cortesanes, amants, dones. Moltes, però, representen ideals poètics a través dels quals la pintura demostra la seva capacitat de rivalitzar amb la poesia quant a demostració de l’ideal estètic de la bellesa. Aquest breu treball pretén examinar les successives interpretacions historiogràfiques que erròniament han identificat la pintura de Flora amb Lucrecia Borja a causa del valor eròtic pejorativament relacionat amb ella, però també vol posar èmfasi en les altres propostes que han permès que l’obra sigui interpretada amb l’exegesi més adequada. Paraules clau: Lucrècia Borja, Pol Coronado, Retrat, Bartolomeo Veneto, Flora Abstract: This study intended to emphasize the identity has been wrong that has reached our days of Lucrezia Borgia and the wrong attribution has been made of some pictures. One of the most paradigmatic paintings is Flora (c.1520), painted by artist Bartolomeo Veneto. This work has gone down in history as one indissoluble portrait of Lucrezia, but recent studies have shown represents an ideal model influenced by the literary context probably related to Pietro Bembo. During the Renaissance, portraits represent much more than a specific and mimetic identity. They are supports of prestige and ideological transmission, of moral virtues, memory, etc. In the Venetian art scene of the early sixteenth century, multiple female portraits often difficult to identify that criticism have related courtesans, mistresses, wives. Many of these paintings also represent poetic ideals through which painting demonstrate its ability to compete with poetry in terms of demonstrating the aesthetic ideal of beauty. This short paper aims to examine the successive historiographical interpretations erroneously identified the painting of Flora with Lucrezia Borgia due to the erotic value related to her pejoratively, but also wants to highlight other proposals that have allowed the work to be performed with the most appropriate exegesis. Keywords: Lucrezia Borgia, Pol Coronado, Portrait, Bartolomeo Veneto, Flora

Published: October 2024

AbstractDiffuse midline gliomas present a particularly intricate and challenging clinical scenario. This rare case involves a patient with comutant H3F3A and FGFR diffuse midline glioma with a clinical presentation of fulminant leptomeningitis. A 22‐year‐old male presented with fatal and fulminant diffuse leptomeningitis. Next‐generation sequencing of plasma and cerebrospinal circulating tumour DNA revealed diffuse midline gliomas with H3F3A and FGFR mutations. Methylome analysis of meningeal tissue collected during autopsy confirmed the diagnosis. Liquid biopsy plays a crucial role in the diagnosis of diffuse midline gliomas, mainly those with exclusively leptomeningeal presentations.

AbstractHigh‐quality and low‐defect perovskite active layer (PVK) and electron transport layer (ETL) are essential for high‐performance perovskite solar cells (PSCs). Herein, an alkylamine salt, cyclohexylmethylammonium chloride (CMACl) is introduced into tin oxide (SnO2) ETL. CMACl, possessing protonated −NH3+ group and Cl− ions, not only effectively inhibits the aggregation of SnO2 colloids and enhances the quality of the ETLs, but also reduces and passivates the defects on ETLs. On the other hand, via the across‐interface effect of alkylamine salt by thermal diffusion, the CMACl‐PbI2 intermediate phase is formed and leads to the high quality of PVK, meanwhile, the defect on the buried interfaces and in the bulk of PVK are passivated by CMA+ and Cl− ions. Consequently, the CMACl‐modified PSC achieves a preeminent power conversion efficiency of 25.47% and excellent stability. This work demonstrates a facile and effective approach for synchronous optimization of ETL and PVK for high‐performance PSCs by across‐interface effect.

Published: October 2024

AbstractLithium‐sulfur batteries offer high energy density but face great safety and cycle life challenges due to the use of Li metal anode. Replacing the Li metal anode with pre‐lithiated carbon anodes can thoroughly address cycling stability and safety issues. Directly contacting Li foil with graphite electrode is one of the most efficient and simple strategy to introduce a high content of lithium source into the sulfur‐carbon full batteries. However, the 100% lithiation of the graphite anode through the direct contact method generates excessive heat and stress heterogeneity, which leads to electrode structure cracking and electrochemical properties fading. This study implements a double‐layer anode to mitigate these issues. A thin layer of hard carbon placed between graphite and Cu foil limits heat generation and stress heterogeneity due to its structural and electrochemical stability. Additionally, differing from traditional electrochemical lithiation, this method gains better solid electrolyte interphase (SEI) for the graphite anode after several cycles. This research highlights the mass production potential of coupling high energy density lithium source‐free cathode materials with various lithium source‐free anodes for constructing long‐cycle and high‐safety rechargeable batteries.
Enabling 2D Electron Gas with High Room‐Temperature Electron Mobility Exceeding 100 cm2 Vs−1 at a Perovskite Oxide Interface

Published: October 2024

AbstractIn perovskite oxide heterostructures, bulk functional properties coexist with emergent physical phenomena at epitaxial interfaces. Notably, charge transfer at the interface between two insulating oxide layers can lead to the formation of a 2D electron gas (2DEG) with possible applications in, e.g., high‐electron‐mobility transistors and ferroelectric field‐effect transistors. So far, the realization of oxide 2DEGs is, however, largely limited to the interface between the single‐crystal substrate and epitaxial film, preventing their deliberate placement inside a larger device architecture. Additionally, the substrate‐limited quality of perovskite oxide interfaces hampers room‐temperature (RT) 2DEG performance due to notoriously low electron mobility. In this work, the controlled creation of an interfacial 2DEG at the epitaxial interface between perovskite oxides BaSnO3 and LaInO3 is demonstrated with enhanced RT electron mobility values up to 119 cm2 Vs−1—the highest RT value reported so far for a perovskite oxide 2DEG. Using a combination of state‐of‐the‐art deposition modes during oxide molecular beam epitaxy, this approach opens up another degree of freedom in optimization and in situ control of the interface between two epitaxial oxide layers away from the substrate interface. Thus this approach is expected to apply to the general class of perovskite oxide 2DEG systems and to enable their improved compatibility with novel device concepts and integration across materials platforms.

Published: October 2024

AbstractMonitoring surface deformation is crucial for the early warning of landslides, facilitating timely preventive measures. Triboelectric nanogenerator (TENG) demonstrates great potential for self‐powered distributed monitoring in remote and power‐scarce landslide areas. However, landslides deform typically at a rate of a few millimeters per day (mm d−1), making it challenging for TENG to directly monitor the deformation process. Herein, a method for monitoring surface deformation of landslides by constructing an ultra‐low‐speed triboelectric displacement sensor (US‐TDS) is reported. Utilizing a force storage‐release device and an accelerator, the US‐TDS can produce obvious sensing signals at a linear input speed of 4.32 mm d−1. The coefficient of determination (R2) for the fitting curve of the pulse signals within the speed range of 21.6 to 129.6 mm d−1 reaches 0.999. Moreover, US‐TDS can detect deformation displacement as small as 0.0382 mm. The stability of US‐TDS displacement measurements is confirmed at a speed of 108 mm d−1, with relative errors under 1%. Ultimately, a real‐time monitoring and early warning system for landslide surface deformation is constructed and verified through a combination of indoor simulations and outdoor experiments. This work provides a feasible solution for the scientific monitoring and early warning of the landslide development.
Label‐Free Raman Probing of the Intrinsic Electric Field for High‐Efficiency Screening of Electricity‐Producing Bacteria at the Single‐Cell Level

Published: October 2024

AbstractThe fabrication of high‐performance microbial fuel cells requires the evaluation of the activity of electrochemically active bacteria. However, this is challenging because of the time‐consuming nature of biofilm formation and the invasive nature of labeling. To address this issue, we developed a fast, label‐free, single‐cell Raman spectroscopic method. This method involves investigating the “pure” linear Stark effect of endogenous CO in the silent region of biological samples, which allows for probing the intrinsic electric field in the outer‐membrane cytochromes of live bacterial cells. We found that reduced outer‐membrane cytochromes can generate an additional intrinsic electric field equivalent to an applied potential of +0.29 V. We also found that the higher the electrical activity of the cell, the larger the generated electric field. This was also reflected in the output current of the constructed microbial fuel cells. Raman spectroscopy was employed to facilitate the assessment of electrochemical activity at the single‐cell level in highly‐diluted bacterial samples. After analysis, inactive bacteria were ablated by laser heating, and 20 active cells were cultured for further testing. The rapid and high‐throughput probing of the intrinsic electric field offers a promising platform for high‐efficiency screening of electrochemically active bacterial cells for bioenergetic and photosynthetic research.
Asymmetric Palladium Migration for Synthesis of Chiral‐at‐Cage o‐Carboranes

Published: October 2024

AbstractMetal migration strategy can offer BH functionalization of o‐carboranes at different positions from where initial bond activation occurs to achieve bifunctionalized o‐carboranes in one reaction. We report in this article an enantioselective 3,4‐bifunctionalization of o‐carboranes via asymmetric Pd migration with a high efficiency and up to 98 % ee. This asymmetric catalysis has a broad substrates scope, leading to the preparation of a class of chiral‐at‐cage o‐carborane derivatives. The enantiocontrol model is suggested on the basis of density functional theory (DFT) results, where the chiral Trost ligand plays a crucial role in this enantioselective Pd migration from exo‐alkenyl sp2 C to the cage B(4) position of o‐carborane.

Published: October 2024

ABSTRACTThe interaction of 2,6‐pyridinedicarboxylicacid (PDA) and 2,2′‐bipyridyl (Bipy) with Co(II), Ni(II), and Cu(II) ions produced new ternary complexes [M (PDA)(Bipy)(H2O)] (M = Co(II), Ni(II), and Cu(II)), which were studied by elemental, spectral (FT‐IR, Mass, UV–Vis), and thermal analysis, and their interaction with Ct‐DNA was thoroughly studied using various methods, including absorption spectroscopy, fluorescence spectroscopy, and viscosity measurements. Spectrophotometric titration and viscosity measurements indicated that all the complexes bind to DNA via the groove mode of binding. The salt‐dependent binding of ternary metal complexes to Ct‐DNA has been studied by a UV–Vis spectrophotometric titration experiment. Furthermore, photocleavage studies were used to examine how the metal complexes interacted with the pBR322 DNA, and the results proved that these compounds have obvious photo cleavage properties. The biological effects were studied by antibacterial activity.
Using Pole–Pole Measurements to Calculate Arbitrary 4‐Point Configurations—An Approach to Make Electrical Resistivity Tomography More Flexible and Time‐Efficient

Published: October 2024

ABSTRACTElectrical resistivity tomography (ERT) is nowadays widely used in archaeological prospection. This study deals with an approach to make ERT more time‐efficient and flexible. It is based on calculating arbitrary 4‐point configurations by superposition of multiple pole–pole measurements. Investigating its applicability for archaeological purposes is the objective of this work. To do so, a synthetic study and a case study are conducted to gain insights into effects of nonideal field conditions, noise susceptibility and other challenges during processing and interpretation. Remains of an early modern manor in Noer served as an exemplary object of investigation. Their high resistivity contrast in relation to the surrounding soil makes them ideal for a functionality test. Beforehand, ground penetrating radar measurements were carried out to constrain the forward model used in the synthetic study. It turns out that the pole–pole conversion is well applicable for archaeological prospection under some conditions. The synthetic study shows that the approach is relatively prone to systematic errors. Therefore, it is recommended to locate the external electrodes at a distance of at least 0.7 times (preferably 1.7 times) the maximum internal electrode spacing from the area of investigation. Other error sources like nonideal electrode coupling must be excluded to keep relative noise levels below 1%. The pole–pole conversion can be considered reliable for absolute noise levels below 0.3 mV. Therefore, an A/D converter resolution of, for example, 16‐bit should be sufficient for a dynamic range of ±10 V. If all conditions are met, the pole–pole conversion has a great potential to make ERT more time‐efficient (up to 50%, depending on configuration sets) and flexible, as it allows to calculate nearly every arbitrary 4‐point configuration in the given setup. Combined with optimization approaches like the ‘Compare R’ method, data sets can also be adapted for specific (archaeological) questions or conditions.

Published: October 2024

AbstractThe antitumor activity of various gold compounds is a promising field of investigation, attracting researchers seeking potential clinical candidates. To advance this research, they explore the complex mechanisms of action of these compounds. Since the discovery of the strong inhibition of thioredoxin reductase by auranofin, the primary mechanism explored has been the inhibition of this enzyme. This inhibition disrupts the redox balance in cells, promoting oxidative stress and triggering cell death. In this review, we analyzed studies from the past decade that measured cellular ROS increase and examined the coordination structures of gold compounds. We also correlate ROS increase with the inhibition of redox‐regulating enzymes, thioredoxin reductase, and glutathione reductase, to elucidate the relationship between these cellular effects and chemical structures. Our data compilation reveals that different structures exhibit varying efficacy: some significantly increase ROS production and inhibit thioredoxin reductase or glutathione reductase, while others elevate ROS levels without affecting these target enzymes, suggesting alternative mechanisms of action. This review consolidates critical evidence, enhancing our understanding of the mechanisms by which these gold complexes act and providing valuable insights for developing new therapeutic strategies against tumor cells.
