Authors: Bracq-Leca Herminie , Bécache Eve 
Published: April 2023

Praticiennes en psychiatrie légale, nous présenterons le parcours d’une patiente suivie dans une unité forensique, en reprenant son cheminement vers le passage à l’acte criminel, nous l’analyserons au regard des fonctions du mythe et de l’histoire de Médée. Notre propos s’articulera autour de réflexions psychopathologiques propres aux femmes auteurs d’infanticide, mettant en exergue les paradoxes de la féminité soulevés par le mythe et la place du couple homme/femme. Dans ce mythe, que peut figurer le couple Médée-Jason de la part perverse dans une relation amoureuse régie par des enjeux de domination entre les partenaires et comment l’issue d’une telle relation est-elle vouée, à une destruction du lien, voire du fruit de ce lien?
Pour une mésologie de l’apprenance
Authors: Cristol Denis 
Published: April 2023

L’article interroge et distingue les notions d’environnement et de milieu à partir d’une triple perspective géographique, phénoménologique et biologique. Il montre en quoi la façon de considérer « ce qui nous entoure » et/ou « ce qui nous constitue » induit des pratiques radicalement différentes de la part du concepteur d’une formation. Il s’appuie sur les travaux d’Augustin Berque relatifs à la mésologie, ou « étude des milieux », pour pointer les enjeux pédagogiques d’individualisation dans le rapport de l’apprenant aux activités qu’il réalise pour apprendre. La compréhension du milieu en tant que conjonction d’une expérience singulière d’un individu coextensive à la transformation des conditions de réalisation de celles-ci est au coeur de l’analyse.

Aims: This study aimed to investigate the effect of gallium nitrate [Ga(NO3)3], an inorganic antimicrobial agent, against the growth and biofilm formation of Staphylococcus aureus on the titanium surface.
Study Design: This study is a laboratory investigation involving the determination of the inhibitory concentration (IC) of Ga(NO3) 3 against the planktonic strain of S. aureus and biofilm formation on titanium coupons.
Place and Duration of Study: Sample: Center of Science and Technology for Sustainability (CCTS), Federal University of São Carlos, SP, Brazil, between March 2020 and March 2022.
Methodology: The inhibitory concentration of gallium nitrate was determined in a 96-well microtiter plate in Muller Hinton broth. The potential of the antimicrobial agent to inhibit biofilm formation by S. aureus on titanium surfaces was evaluated by Scanning Electron Microscopy (SEM). The cytotoxicity potential of Ga(NO3)3 was determined on V79 cells.
Results: The results showed that the susceptibility of gallium nitrate against S. aureus was 1.40 µM, while SEM images revealed that concentrations of 90 µM inhibited biofilm formation by S. aureus.
Conclusion: This research has shown promising results regarding gallium nitrate's potential of inhibiting the growth of both planktonic and sessile S. aureus cells. In addition, coating titanium surfaces with Ga(NO3)3 would be an extra alternative to prevent implant-associated infections due to its non-toxicity to cells.

ImportanceLow-dose combination (LDC) antihypertensives consisting of 3 or 4 blood pressure (BP)–lowering drugs have emerged as a potentially important therapy for the initial management of hypertension.ObjectiveTo assess the efficacy and safety of LDC therapies for the management of hypertension.Data SourcesPubMed and Medline were searched from date of inception until September 2022.Study SelectionRandomized clinical trials comparing LDC consisting of 3 or 4 BP-lowering drugs compared to either monotherapy, usual care, or placebo.Data Extraction and SynthesisData were extracted by 2 independent authors and synthesized using both random and fixed-effects models using risk ratios (RR) for binary outcomes and mean differences for continuous outcomes.Main Outcomes and MeasuresThe primary outcome was mean reduction in systolic BP (SBP) between LDC and monotherapy, usual care, or placebo. Other outcomes of interest included the proportion of patients achieving BP less than 140/90 mm Hg, rates of adverse effects, and treatment withdrawal.ResultsSeven trials with a total of 1918 patients (mean [mean range] age, 59 [50-70] years; 739 [38%] female) were included. Four trials involved triple-component LDC and 3 involved quadruple-component LDC. At 4 to 12 weeks follow-up, LDC was associated with a greater mean reduction in SBP than initial monotherapy or usual care (mean reduction, 7.4 mm Hg; 95% CI, 4.3-10.5) and placebo (mean reduction, 18.0 mm Hg; 95% CI, 15.1-20.8). LDC was associated with a higher proportion of participants achieving BP less than 140/90 mm Hg at 4 to 12 weeks compared to both monotherapy or usual care (66% vs 46%; RR, 1.40; 95% CI, 1.27-1.52) and placebo (54% vs 18%; RR, 3.03; 95% CI, 1.93-4.77). There was no significant heterogeneity between trials enrolling patients with and without baseline BP-lowering therapy. Results from 2 trials indicated LDC remained superior to monotherapy or usual care at 6 to 12 months. LDC was associated with more dizziness (14% vs 11%; RR 1.28, 95% CI 1.00-1.63) but no other adverse effects nor treatment withdrawal.Conclusions and RelevanceThe findings in the study showed that LDCs with 3 or 4 antihypertensives were an effective and well-tolerated BP-lowering treatment option for the initial or early management of hypertension.
Proposal of deformation history integral‐type hysteresis model considering performance change of high‐damping rubber bearings and verification using substructure real‐time online testing system for seismically isolated structure

Published: April 2023

AbstractA deformation history integral (DHI)‐type hysteresis model is an elastic–plastic model that was originally developed for high‐damping rubber bearings (HDRs). The model can show the complex characteristics of HDRs. However, the model cannot accurately consider performance changes due to production variation, temperature dependence, repeated loading dependence, etc. Herein, an improved DHI model that can accurately reflect performance changes is proposed. The main contributions of this study are as follows: (1) To reflect performance change, the DHI model is improved by defining material parameters as a function of the performance change ratios. (2) To accurately reflect repeated loading dependence, including the scragging effect, the DHI model is improved by defining the performance change ratios as a function of the cumulative energy per unit volume. The authors have previously developed a substructure real‐time online testing system. The system performs a time‐history response analysis via analysis and testing systems. To verify the accuracy of the proposed model, a time‐history response analysis is performed using the proposed model, and the results of the substructure real‐time online testing system are compared. The results show that the proposed new hysteresis model can predict the complex behavior of HDRs more accurately than existing analysis models.
Nonlinear optimal control for the rotary double inverted pendulum

Published: April 2023

AbstractThe control problem of the rotary double inverted pendulum (double Furuta pendulum) is nontrivial because of underactuation and strong nonlinearities in the associated state‐space model. The system has three degrees of freedom (one actuated and two unactuated joints) while receiving only one control input. In this article, a novel nonlinear optimal (H‐infinity) control approach is developed for the dynamic model of the rotary double inverted pendulum. First, the dynamic model of the double pendulum undergoes approximate linearization with the use of first‐order Taylor series expansion and through the computation of the associated Jacobian matrices. The linearization process takes place at each sampling instance around a temporary operating point which is defined by the present value of the system's state vector and by the last sampled value of the control inputs vector. At a next stage a stabilizing H‐infinity feedback controller is designed. To compute the controller's feedback gains an algebraic Riccati equation has to be solved at each time‐step of the control algorithm. The global stability properties of the control scheme are proven through Lyapunov analysis. To implement state estimation‐based control without the need to measure the entire state vector of the rotary double‐pendulum the H‐infinity Kalman filter is used as a robust state observer. The nonlinear optimal control method achieves fast and accurate tracking of setpoints by all state variables of the rotary double inverted pendulum under moderate variations of the control input.

AbstractThe applications of bioresponsive materials are limited by the low levels of physiological triggers and spatiotemporal barriers in vivo. To address these issues, a light‐controlled “Trojan horse” strategy is proposed by encapsulating a photo‐caged reducing agent within reduction‐responsive polymer vesicles. The polymersomes act as an enzyme‐inspired nanoreactor for efficient photo‐synthesis of dithiothreitol in situ, which attacks the disulfide bonds in polymer backbones and disintegrates the vehicles from the inside in a nanoconfined space. The assembly‐catalyzed photoreduction reaction overcomes the temporal and spatial barriers for hyper‐responsivity and enables ultrafast drug release even at 0.014 mm of dithiothreitol residues, a concentration 715 times lower than that required to cleave disulfide bonds. In addition, in both vitro and vivo, the equipment of upconverting nanoparticles and photothermal agents creates a near‐infrared light‐activated and self‐heating nanoreactor, which allows for efficient intracellular drug delivery and excellent photo‐chemo‐immunotherapy of tumors. This work presents a new approach to designing smart materials and a promising platform for on‐demand drug delivery applications.

AbstractFlexible aqueous zinc‐ion batteries (AZIBs) with high safety and low cost hold great promise for potential applications in wearable electronics, but the strong electrostatic interaction between Zn2+ and crystalline structures, and the traditional cathodes with single cationic redox center remain stumbling blocks to developing high‐performance AZIBs. Herein, freestanding amorphous vanadium oxysulfide (AVSO) cathodes with abundant defects and auxiliary anionic redox centers are developed via in situ anodic oxidation strategy. The well‐designed amorphous AVSO cathodes demonstrate numerous Zn2+ isotropic pathways and rapid reaction kinetics, performing a high reversible capacity of 538.7 mAhg‐1 and high‐rate capability (237.8 mAhg‐1@40Ag‐1). Experimental results and theoretical simulations reveal that vanadium cations serve as the main redox centers while sulfur anions in AVSO cathode as the supporting redox centers to compensate local electron‐transfer ability of active sites. Significantly, the amorphous structure with sulfur chemistry can tolerate volumetric change upon Zn2+/H+ insertion and weaken electrostatic interaction between Zn2+ and host materials. Consequently, the AVSO composites display alleviated structural degradation and exceptional long‐term cyclability (89.8% retention after 20 000 cycles at 40 Ag‐1). This work can be generally extended to various freestanding amorphous cathode materials of multiple redox reactions, inspiring development of designing ultrafast and long‐life wearable AZIBs.

Published: April 2023

AbstractA new wetting mechanism, termed electro‐elastic wetting, and methods to exploit it for droplet manipulation are proposed and demonstrated. The system consists of a droplet of dielectric liquid, an elastic and conductive membrane as its shell, and an electrode‐dielectric composite as its substrate. Activation is by an electric field applied between the membrane and the substrate. The equilibrium shape of the droplet is determined by the balance of membrane tension and electrostatic attraction. It is shown that the contact angle of the droplet is governed by a modified Young–Lipmann Equation. It is then demonstrated that it is possible to transport the droplet along a controlled direction, as well as to actively tune its shape, topography, and position by manipulating the spatial distribution of the electrical force.

Published: April 2023

AbstractA hierarchical structure is successfully synthesized by coating polypyrrole (PPy) on the surface of carbon/saponite superlattice (denoted as PPy@C/SAP), and applied as low volume‐expansion insertion‐type anode for Li, Na, K storage.The synergistic effect of metal Ni, Fe doping, carbon/silicate superlattice, abundant oxygen vacancies and PPy coating leads to a good electronic conductivity and large current discharging capability. As a Si‐based material, PPy@C/SAP has excellent storage capability for Li (659 mAh g−1 after 1000 cycles at 2 A g−1 and 550 mAh g−1 after 1000 cycles at 5 A g−1), Na (maximum specific capacity of 533 and 327 mAh g−1 after 50 cycles) as well as K (236 mAh g−1 after 100 cycles). XPS, XANES, XRD, FTIR, HRTEM, SEM are used to detect the hybrid mechanism (bulk insertion and surface conversion) with a volume expansion as low as 9%. Insertion reaction driven by valence state change of Ni, Fe, Si (Ni0⇔Ni2+, Fe0⇔Fe3+, Si2+⇔Si4+) in laminates and conversion reactions between LiOH/Li2CO3 and LiH/Li2C2 catalyzed by Ni° contribute to the high performance. In the whole electrochemical process, layered structure is retained while the conversion reactions of LiOH (prodeced by laminates dehydroxylation) and Li2CO3 (electrolyte decomposition) cause the dynamic evolution of solid ectrolyte interphase. This study develops a promising Si‐based anode material for lithium ion batteries, sodium ion batteries and potassium ion batteries, which is significant for designing long cycle life rechargeable batteries.

Published: April 2023

AbstractSpreading the formic acid (HCOOH) fuel cells demands a better anode electrocatalyst for the oxidation of formic acid. The catalytic efficiency of platinum (Pt)– the only choice of practicability, is mainly limited by its intrinsic affinity to CO, thus desiring a proper release. Herein, theoretical calculations are first leveraged to find that the introduction of iridium (Ir) can facilitate HCOOH oxidation with robust CO tolerance through a dehydrogenation pathway. Then, this strategy experimentally by designing a new trimetallic catalyst of 2D porous PtIrBi nanoplates (p‐PtIrBi NPs) is implemented. The optimized p‐PtIrBi NPs/C exhibits a very high mass activity of 8.2 A mg−1pt and a high retention rate of 55.9% after the durability test, which is among the best formic acid oxidation catalysts reported to date, much higher than those of PtIrBi NPs/C, PtBi NPs/C, and Pt/C. The CO‐stripping and in situ Fourier transform infrared (FTIR) experiments collectively evidence that two types of due site, i.e., “Pt‐Bi” and “Ir‐Bi”, endow the catalyst with suppressed CO‐poisoning property to achieve super‐high activity and stability for formic acid oxidation reaction.

AbstractMicrofluidics have transformed diagnosis and screening in regenerative medicine. Recently, they are showing much promise in biofabrication. However, their adoption is inhibited by costly and drawn‐out lithographic processes thus limiting progress. Here, multi‐material fibers with complex core‐shell geometries with sizes matching those of human arteries and arterioles are fabricated employing versatile microfluidic devices produced using an agile and inexpensive manufacturing pipeline. The pipeline consists of material extrusion additive manufacturing with an innovative continuously varied extrusion (CONVEX) approach to produce microfluidics with complex seamless geometries including, novel variable‐width zigzag (V‐zigzag) mixers with channel widths ranging from 100–400 µm and hydrodynamic flow‐focusing components. The microfluidic systems facilitated rapid mixing of fluids by decelerating the fluids at specific zones to allow for increased diffusion across the interfaces. Better mixing even at high flow rates (100−1000 µL min−1) whilst avoiding turbulence led to high cell cytocompatibility (>86%) even when 100 µm nozzles are used. The presented 3D‐printed microfluidic system is versatile, simple and efficient, offering a great potential to significantly advance the microfluidic platform in regenerative medicine.

AbstractSolar cells (PSCs) with quasi‐2D Ruddlesden–Popper perovskites (RPP) exhibit greater environmental stability than 3D perovskites; however, the low power conversion efficiency (PCE) caused by anisotropic crystal orientations and defect sites in the bulk RPP materials limit future commercialization. Herein, a simple post–treatment is reported for the top surfaces of RPP thin films (RPP composition of PEA2MA4Pb5I16 <n> = 5) in which zwitterionic n‐tert‐butyl‐α‐phenylnitrone (PBN) is used as the passivation material. The PBN molecules passivate the surface and grain boundary defects in the RPP and simultaneously induce vertical direction crystal orientations of the RPPs, which lead to efficient charge transport in the RPP photoactive materials. With this surface engineering methodology, the optimized devices exhibit a remarkably enhanced PCE of 20.05% as compared with the devices without PBN (≈17.53%) and excellent long‐term operational stability with 88% retention of the initial PCE under continuous 1‐sun irradiation for over 1000 h. The proposed passivation strategy provides new insights into the development of efficient and stable RPP‐based PSCs.
Bio‐Carbon as a Means of Carbon Management in Roads

Published: April 2023

AbstractThis paper introduces biocarbon, referred to as biochar, as a novel eco‐friendly and cost‐effective additive to increase interactions among bitumen components while facilitating carbon management in roadway infrastructures. It is hypothesized that functional groups on biochar surfaces enhance interactions between biochar and bitumen constituents. This in turn enhances mechanical properties and durability of asphalt pavements. This study uses biochars derived from six different types of woody biomass and one type of algae, and polyethylene terephthalate granules as a carrier to introduce biochar to bitumen. Quantum‐based molecular modeling and noncovalent interaction analysis show that algal biochar interacts more effectively with bitumen components. The enhanced interaction of algal biochar is attributed to its surface functional groups including reactive nitrogen‐ and oxygen‐carrying functional groups. The rheological characterization of bitumen doped with different biochars confirms that the lowest separation index occurs for bitumen containing algal biochar, which also exhibits the highest percent of elastic recovery and resistance to permanent deformation. The study suggests that asphalt pavement durability can be enhanced by selection of the proper biochar to increase intermolecular interactions. Promising results for the algae biochar promote its use in carbon management for roadway infrastructure by sequestering CO2 from air through photosynthesis of algae biomass.

AbstractStability and scalability are essential and urgent requirements for the commercialization of perovskite solar cells (PSCs), which are retarded by the non‐ideal interface leading to non‐radiative recombination and degradation. Extensive efforts are devoted to reducing the defects at the perovskite surface. However, the effects of the buried interface on the degradation and non‐radiative recombination need to be further investigated. Herein, an omnibearing strategy to modify buried and top surfaces of perovskite film to reduce interfacial defects, by incorporating aluminum oxide (Al2O3) as a dielectric layer and growth scaffolds (buried surface) and phenethylammonium bromide as a passivation layer (buried and top surfaces), is demonstrated. Consequently, the open‐circuit voltage is extensively boosted from 1.02 to 1.14 V with the incorporation of Al2O3 filling the voids between grains, resulting in dense morphology of buried interface and reduced recombination centers. Finally, the impressive efficiencies of 23.1% (0.1 cm2) and 22.4% (1 cm2) are achieved with superior stability, which remain 96% (0.1 cm2) and 89% (1 cm2) of its initial performance after 1200 (0.1 cm2) and 2500 h (1 cm2) illumination, respectively. The dual modification provides a universal method to reduce interfacial defects, revealing a promising prospect in developing high‐performance PSCs and modules.
