Equivalence of hypotheses and Galilean censure in Leibniz: A conspiracy or a way to moderate censure?
Authors: Adomaitis Laurynas 
Published: June 2019

En 1689, à Rome, et durant six mois, Gottfried Wilhelm Leibniz (1646-1716) s’est occupé de la question de la censure copernicienne et galiléenne. L’interprétation habituelle des articles de Rome suggère que la tentative leibnizienne pour lever la censure copernicienne était uniquement dérivée de l’équivalence d’hypothèses provenant de la relativité du mouvement ; elle impliquait pour Leibniz de compromettre sa conviction quant à la véracité de l’hypothèse copernicienne en affirmant que celle-ci ne devrait être interprétée que de manière instrumentale ; enfin, elle accompagnait une plaidoirie pour l’abolition totale de la censure. Au contraire, je soutiens que si les hypothèses étaient simplement équivalentes, cela ne fournirait aucune raison pour lever la censure de Galilée (qui soutenait que la Terre se meut réellement et que l’Église a commis une erreur sur ce point) ; que la position de Leibniz dans sa cosmologie était bien une sorte d’instrumentalisme et qu’aucun compromis n’était donc nécessaire ; enfin que Leibniz défendait une position selon laquelle Galilée aurait dû être soumis à la censure, non pas à cause de sa physique, mais à cause de sa mauvaise interprétation du statut de l’Écriture.
Unions mouvementées
Authors: Vouilloux Bernard 
Published: June 2019

Quelques représentations fameuses ont mis en scène les relations qui, au xix e siècle, unissent peintres, écrivains, musiciens, critiques, mécènes et collectionneurs, contribuant ainsi à l’édification d’un véritable mythe fondateur. Au lien sororal qui inscrivait les relations entre poésie et peinture dans le cadre humaniste de l’ Ut pictura poesis se substitue la fraternité artiste, fondée sur des engagements esthétiques partagés : l’entente n’est pas donnée d’emblée, prescrite par la poétique, elle est gagée sur l’œuvre dans laquelle chacun est engagé. C’est dire que ces unions sont, par définition, fugaces. Face à elles se dessinent des alternatives « fondamentalistes », des retours : à l’imagerie populaire, aux primitifs italiens. Et se dresse un défi : celui d’une modernité à double visage, la démocratie étant pour certains le fourrier de l’uniformisation culturelle.
Le souffle d’une aile : poétiques de l’éventail chez Mallarmé et Claudel
Authors: Souchard Flora 
Published: June 2019

Mallarmé et Claudel, malgré leurs différences poétiques et existentielles, peuvent se rejoindre dans l’attention qu’ils ont portée à un objet particulier : l’éventail. Ainsi Mallarmé l’utilise-t-il comme support de courts poèmes, quand Claudel lui rend hommage dans l’inspiration orientale qui a guidé ses Cent phrases pour éventails . Malgré l’hétérogénéité des supports qui ont vu naître ces poèmes – éventails réels ou livre japonais – l’objet ailé concentre des problématiques communes aux deux poètes. Volonté de dépasser la lourdeur éditoriale et émancipation des règles graphiques font souffler un vent de liberté sur ces textes, rythmés de battements nouveaux. Pliant la plume et l’encre aux exigences du visuel, voire la syntaxe à l’influence de la pensée japonaise, les poètes révèlent au prisme de l’éventail une réflexion esthétique qu’il est fécond de relire dans son contexte original d’écriture.
Ces étranges machines extrême-occidentales
Authors: Métailié Georges , Vérin Hélène 
Published: June 2019

Fruit d’une collaboration entre un lettré chinois converti au christianisme Wang Zheng (1571-1644) et un missionnaire jésuite Johann Schreck, dit Terrentius (1576-1630) le livre intitulé « Essentiel des explications et représentations de merveilleuses machines d’Extrême-Occident » Yuanxi qiqi tushuo luzui, fut publié en 1627. Il rassemble dans un même ouvrage des données théoriques de la science des poids, d’analyse et de calcul de leurs applications dans les machines simples et de présentation de divers modèles de machines. Ce rassemblement constitue une approche inédite qui n’a pas sa pareille en Occident. C’est cette innovation que nous proposons d’interroger.
Routes, rutters, navigational techniques and the development of navigational aids in traditional Chinese seagoing: The case of the compass
Authors: Davies Stephen 
Published: June 2019

This paper will consider magnetic compasses as navigational aids in traditional Chinese seagoing in the light of the history and development of the science and technology of the magnetic compass. It will contend that in principle the magnetic pointers carried aboard traditional Chinese vessels (and equivalently equipped vessels elsewhere) before the late 17th century cannot have been reliable navigational aids and that no prudent mariner would have used them as such. The most widely accepted pre-17th century traditional seagoing compass water-bowl design will be evaluated according to the known, iron fastened, multi-cellular box girder structure of contemporary Chinese seagoing ships and to the waters in which they operated. A similar evaluation will be made of the post-17th century, dry pivot design. Both will be compared to the development of the magnetic compass, and of theories of geomagnetism and compass design between the 12th and 19th centuries in the west. Some conjectures will be ventured after the foregoing analysis as to the meaning and practical application of the “needle paths” associated traditional Chinese route maps and rutters.
Les malentendus de la technologie
Authors: Loeve Sacha , Deldicque Timothée 
Published: June 2019

Le terme actuel de technologie, en désignant directement les réalités techniques et non leur étude, les réduit au produit d’un logos appliqué qui les place dans le giron des sciences exactes et néglige leur statut de faits sociaux susceptibles d’une compréhension par les sciences humaines. Critiquant cet usage, beaucoup militent pour rétablir dans toute sa clarté la distinction entre les techniques et la technologie dans son sens originel de théorie des techniques. Cet article examine ces critiques et questionne leur volonté de dissiper les malentendus de la technologie. Il affirme que le concept de « technique » auquel on voudrait revenir est en fait postérieur à celui de technologie ; que le caractère paradigmatique de la technologie de Beckmann est discutable ; et que la source de l’indétermination première comme de la surdétermination actuelle de la technologie réside dans son ambivalence irréductible entre logos de technè et technè du logos. Nous soutenons finalement qu’il existe aussi de bonnes raisons de confondre technique et technologie, comme le fait l’usage actuel, qui peut dès lors être justifié, mais à condition de le réinscrire dans un pluralisme des modes d’existence et de connaissance technologiques.

Le Club français de la médaille et le musée du 11 Conti
Authors: Coullaré Béatrice 
Published: June 2019

La Monnaie de Paris a une longue tradition de collaboration avec des artistes indépendants. Celle-ci a été facilitée par l’emploi du tour à réduire qui a permis aux modeleurs et aux sculpteurs de créer librement leurs œuvres sans devoir maîtriser la gravure en taille directe. Forte de son savoir-faire, c’est à partir de la seconde moitié du xxe siècle que la Monnaie de Paris s’est engagée dans un programme de valorisation de l’art de la médaille contemporaine grâce à la vision de Pierre Dehaye (1921-2008), son directeur. En poste depuis un an, il crée en 1963 le Club français de la médaille pour promouvoir et défendre cet art auprès des amateurs, des collectionneurs et du public. Grâce au dépôt légal, un exemplaire de chaque médaille frappée ou fondue pour ce club est entré dans les collections patrimoniales du musée du 11 Conti. Ce fonds est aujourd’hui valorisé par des expositions dossiers qui donnent à découvrir la richesse thématique et stylistique de cette collection unique.
The importance of museum collections in determining biodiversity patterns, using a freshwater mussel Unio caffer (Krauss 1848) as an example

Published: June 2019

Background: Two recent distributional maps of the African freshwater mussel Unio caffer (Krauss 1848) in South Africa represented an incomplete picture compared to the records held by the national museums.Objectives: This study is partly in response to them, with the aim to compare and contrast the distribution maps of the published papers with the distribution records held by the national museums.Method: We requested the distribution records of U. caffer from four South African museums. We visited and worked on the U. caffer collections of three of these museums to confirm the taxonomic identity of their specimens and gather occurrence records. We also extracted the distributional records from the two published maps, and plotted all these records using the geographic information system, ESRI ArcGIS.Results: The distribution map based on the museum records showed that this species occurred in all nine provinces of the country, thus revealing a much broader historical occurrence than previous known.Conclusion: This study demonstrates the crucial function of museums, natural history collections in facilitating understanding about biodiversity patterns using U. caffer distribution as an example. However, as museum records mainly show historical occurrence, there is a need to conduct further studies to assess the current population trends of this species. Although the current International Union for Conservation of Nature (IUCN) conservation assessment of this species is Least Concern, pressures on native fish, which host the larval stages of this mussel, and the declining environmental conditions of rivers in the country may affect the conservation status in the near future.

ImportanceVenous thromboembolism (VTE) is a severe complication after microsurgical free tissue transfer (FTT) to the head and neck. Hypothermia during surgery is a modifiable risk factor, and avoiding it may reduce the postoperative VTE rate.ObjectiveTo assess the association between hypothermia (temperature &amp;lt;36 °C) and postoperative VTE and free flap pedicle thrombosis rates after head and neck reconstruction with FTT.Design, Setting, and ParticipantsThis retrospective cohort study in a tertiary academic referral center used prospective and retrospective database and medical record data collected for patients who underwent head and neck reconstruction with FTT between January 1, 2012, and August 31, 2023. Temperature over time was classified as normothermia (temperature ≥36 °C), hypothermia (&amp;lt;36 °C) for more than 30 minutes and less than 120 minutes, and hypothermia for 120 minutes or more.ExposureVenous thromboembolism.Main Outcomes and MeasuresThe study outcomes were VTE events and thrombosis of the free flap pedicle that required revision surgery. Univariable and multivariable regressions were used to test the association between the outcomes and clinical factors.ResultsA total of 1078 patients (mean [SD] age, 61.3 [12.6] years; 724 males [67.2%]; mean [SD] Caprini score, 6.4 [2.1]) were included. The VTE and pedicle thrombosis rates were 3.2% (35 patients) and 2.2% (24 patients), respectively. In a multivariable model controlled for Caprini score and chemoprophylaxis, VTE was associated with hypothermia of more than 30 minutes and less than 120 minutes (odds ratio [OR], 3.82; 95% CI, 0.99-14.07) and hypothermia of 120 minutes or longer (OR, 3.55; 95% CI, 1.05-11.95). Free flap pedicle thrombosis was not associated with hypothermia (OR, 0.61; 95% CI, 0.26-1.43).Conclusions and RelevanceThese findings suggest that preventing hypothermia during microsurgical FTT to the head and neck may decrease the postoperative rate of VTE. Future studies should explore the optimal intraoperative body temperature range that may prevent the development of VTE without compromising patient safety.
Personalized federated learning for abdominal multi‐organ segmentation based on frequency domain aggregation

Published: December 2024

AbstractPurposeThe training of deep learning (DL) models in medical images requires large amounts of sensitive patient data. However, acquiring adequately labeled datasets is challenging because of the heavy workload of manual annotations and the stringent privacy protocols.MethodsFederated learning (FL) provides an alternative approach in which a coalition of clients collaboratively trains models without exchanging the underlying datasets. In this study, a novel Personalized Federated Learning Framework (PAF‐Fed) is presented for abdominal multi‐organ segmentation. Different from traditional FL algorithms, PAF‐Fed selectively gathers partial model parameters for inter‐client collaboration, retaining the remaining parameters to learn local data distributions at individual sites. Additionally, the Fourier Transform with the Self‐attention mechanism is employed to aggregate the low‐frequency components of parameters, promoting the extraction of shared knowledge and tackling statistical heterogeneity from diverse client datasets.ResultsThe proposed method was evaluated on the Combined Healthy Abdominal Organ Segmentation magnetic resonance imaging (MRI) dataset (CHAOS 2019) and a private computed tomography (CT) dataset, achieving an average Dice Similarity Coefficient (DSC) of 72.65% for CHAOS and 85.50% for the private CT dataset, respectively.ConclusionThe experimental results demonstrate the superiority of our PAF‐Fed by outperforming state‐of‐the‐art FL methods.

AbstractNanoscale redox‐active molecular films are promising candidates for next‐generation energy storage applications due to their ability to facilitate long‐range charge transport. However, establishing stable and efficient electrode‐molecule interfaces remains a critical challenge. In this study, the properties of redox‐active copper‐polypyridyl thin films covalently bonded to graphite rods are explored, investigating their potential as supercapacitors. Using an electrochemical grafting method, robust covalent interfaces are created, resulting in copper‐polypyridyl films prepared on graphite rods and indium tin oxide (ITO) electrodes, exhibiting both Cu(II) and Cu(I) redox states. These redox‐active mettalo‐oligomeric films demonstrate a structural transition between octahedral and tetrahedral geometries around the Cu(II), and Cu(I), respectively contributing to their charge storage capabilities. The combination of an electrical double‐layer capacitance and pseudocapacitance through Faradaic charge transfer is evaluated in different acidic electrolytes, showing significant capacitance enhancement. Notably, proton‐coupled electron transfer (PCET) at free pyridine‐N sites in Cu(I) polypyridyl complex is identified as a key factor in their distinct behavior in aqueous solutions, a finding supported by computational studies. This study shows the potential of binder‐free thin films for efficient supercapacitor applications, with a maximum areal capacitance of 6.8 mF cm⁻2 in aqueous media, representing an 1840% improvement over bare graphite rods.

Published: December 2024

AbstractTransition metal oxide shows great potential in catalytic formaldehyde (HCHO) pollution degradation at room temperature, while it is still difficult to overcome the efficiency attenuation caused by limited reactive oxygen species (ROS) generation during catalysis. An elastic spongy catalyst with Cu‐modified polydimethylsiloxane (PDMS) organic skeleton (PDMS@Cu) supported hydroxy‐modified MnOx (MnOx‐OH) is prepared hereon, named PDMS@Cu/MnOx‐OH. Deformation of the elastic carrier causes the contact‐separation friction between Cu and PDMS to generate electrostatically induced nonuniform charges, which provide enriched electrons and transient electric field (EF) to enhance ROS generation and HCHO catalytic oxidation. In HCHO dynamic tests (∼12 ppm at the weight hourly space velocity (WHSV) of 120 000 mL gcat.−1 h), the catalyst PDMS@Cu/MnOx‐OH achieved ∼100% HCHO removal efficiency, with an HCHO‐to‐CO2 conversion efficiency of 82.47%, which is 32.47% higher than that without non‐uniform electrostatic charges, and sustained complete real‐time HCHO degradation within 24 h at room temperature. Coupled with Density Functional Theory (DFT) calculations and COMSOL physics simulations, the potential pathway of nonuniform surface charges and transient EF enhancing HCHO catalytic oxidation is unveiled, offering a theoretical foundation and novel strategy for efficient and long‐term indoor pollutant degradation under the action of sustainably electrostatically induced charges.

AbstractThermoelectric materials, as key materials for realizing efficient conversion of thermal and electrical energy, are crucial for renewable energy utilization and efficient energy management. However, materials with high negative thermoelectric coefficients are relatively rare. Herein, inspired by the structure and function of plant stem which is capable of blocking heavy metal ions, chitosan/CuCl2 hydrogel (ChCu) with a huge negative thermoelectric coefficient is reported. The ChCu displayed lamellar porous structure, which is constructed synergistically by freeze‐casting technique and complexation between Cu2+ and chitosan. In a ChCu hydrogel subjected to a temperature gradient, most of the Cu2+ is immobilized within the chitosan matrix by complexation, while the thermal migration of the unbound Cu2+ is further intercepted by the special layered porous structure. On the contrary, Cl− migrates unhindered to the cold end and accumulates, which realizes selective migration and distribution of ion/counterion. As a result, ChCu exhibits a thermoelectric coefficient as high as ‐23.8 mV K−1, and can respond rapidly with a thermal voltage of 4.0 mV under a small temperature difference (ΔT = 0.3 K). This work reveals the significant influence of the polymer aggregate structure on the thermal diffusion of ions, providing an innovative strategy in designating thermoelectric materials with high‐performance, high‐efficiency and environmentally friendly.

Published: December 2024

AbstractRegulation of bone microenvironment (BME) including innate pH values and metal ions affects cellular functions and activities of osteoblasts and osteoclasts, thereby significantly influencing the process of bone regeneration. How to achieve multiple effective regulations of the BME through cascade effects via facile material design and fabrication to significantly facilitate osteogenesis remains a challenge. Herein, a facilely‐designed resorbable guided bone regeneration membrane (PCL/DEX@Ca‐Zol) based on a drug‐loaded metal‐organic framework is reported. Thereinto, calcium ions, zoledronic acid, and dexamethasone embedded in the membrane can be responsively released specifically inside bone defect in an acid‐triggered manner to synergistically regulate BME by neutralization of pH value, enhancement of osteogenic differentiation and mineralization, and inhibition of osteoclasts in one‐go. Along with polycaprolactone as a structural support in the membrane for bone regeneration with fully utilized components of the composite membrane material, enhances bone regeneration with minimized side effects is accordingly achieved with the assistance of effective modulation of BME through multiple cascade effects.

Published: December 2024

AbstractSide‐emitting optical fibers allow light to be deliberately outcoupled along the fiber. Introducing a customized side‐emission profile requires modulation of the guiding and emitting properties along the fiber length, which is a particular challenge in continuous processing of soft waveguides. In this work, it is demonstrated that multimaterial extrusion printing can generate hydrogel optical fibers with tailored segments for light‐side emission. The fibers are based on diacrylated Pluronic F‐127 (PluDA). 1 mm diameter fibers are printed with segments of different optical properties by switching between a PluDA waveguiding ink and a PluDA scattering ink containing nanoparticles. The method allows the fabrication of fibers with segment lengths below 500 microns in a continuous process. The length of the segments is tailored by varying the switching time between inks during printing. Fibers with customized side‐emission profiles along their length are presented. The functionality of the printed fibers is demonstrated by exciting fluorescence inside a surrounding 3D hydrogel. The presented technology and material combination allow unprecedented flexibility for designing soft optical fibers with customizable optical properties using simple processes and a medical material. This approach can be of interest to improve illumination inside tissues for photodynamic therapy (PDT).
