Influence of the Size of the Metallacycle of P‐NHC Mn Complexes for the Hydrogenation of Esters

Chelate ring size is a key but underexplored parameter in the design of manganese‐based hydrogenation catalysts. Here, we report the synthesis and characterization of Mn(I) NHC–phosphine complexes [Mn‐5] C7 featuring a seven‐membered chelate ring and their application to the hydr...

Flying through the plasmasphere to optimize low-energy ion measurements

The Juice flyby of Earth in August 2024 gave us the first chance to evaluate the performance of the Jovian Plasma Dynamics and Composition analyzer (JDC) in environments similar to those expected at Jupiter. JDC is one of the sensors belonging to the Particle Environment Package...

A CsWRKY46-CsPBL9-CsARI1 tripartite regulatory module coordinates H2O2 production and callose deposition in citrus fruit immunity

Plant immunity against pathogens involves multiple immune responses and intricate regulatory networks. However, how immune networks are deployed in fruit remains poorly understood. Here, we show that citrus fruit immune responses, including hydrogen peroxide (H 2 O 2 ) production...

Net carbon losses in Central African forests revealed by high-resolution biomass change maps

Dense humid forests in Central Africa hold vast biomass carbon stocks but are increasingly affected by small-scale disturbances that are difficult to detect with current satellite observations. Here, we generate 10 m canopy height maps for 2019–2022 using deep learning with space...

Computer-Aided Entrainer Design for Extractive Distillation Using Infinitely Sharp Splits

Abstract We present an integrated product-process design framework for ranking heavy entrainer candidates for minimum-boiling azeotrope separation, corresponding to the Serafimov class (1.0-1a), the most common such case. The framework combines computer-aided molecular design (CA...

Anesthesia TeleConsultation for Pediatric preoperative assessment: a large national prospective multicentric study in children (TeleCCCAP)

Background: While interest in pediatric anesthesia teleconsultation is growing, published data remain scarce. This study evaluated the feasibility of anesthesia teleconsultation in children, providing a comprehensive analysis of failure, quality, dedicated time and satisfaction....

Trend to Equilibrium and Diffusion Limit for the Inertial Kuramoto–Sakaguchi Equation

Abstract. In this paper, we study the inertial Kuramoto–Sakaguchi equation for interacting oscillatory systems. On the one hand, we prove the convergence toward corresponding phase-homogeneous stationary states in weighted Lebesgue norm sense when the coupling strength is small e...

Unravelling the impact of nitrogen deprivation on the morphology and nanomechanical properties of Parachlorella kessleri

Abstract Nitrogen deprivation is commonly applied to enhance lipid accumulation in microalgae for third-generation biofuel production. However, its influence on cell wall morphology and nanomechanical properties, which critically affect downstream processing, remains poorly explo...

An Open Database of Lunar Regolith and Simulants Properties

ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems. Howev...

Ground states on a fractured strip and one-dimensional reduction

We consider the nonlinear Schrödinger equation on a strip with Neumann boundary conditions and a delta condition at x = 0 . We first show the existence of ground states as minimizers of the action or of the energy under suitable constraints. We then prove that the energy minimize...

Revealing archaeological olive diversity: insights from stone geometric morphometrics, experimental charring, and varietal identification (Port-la-Nautique, France, Roman period)

The cultivated olive tree, domesticated in the Levant by the mid-5th millennium BCE, spread westward across the Mediterranean to reach southern France by 600 BCE. Although geometric morphometrics applied to archaeological olive stones has provided insights into this diffusion, mo...

Valorization of Wheat Straw Hydrolysate into Succinic Acid by Fermentation with Actinobacillus succinogenes

Succinic acid (SA) production from agro-industrial waste, such as lignocellulosic biomass, has been gaining interest. Traditionally, it is synthesized from petrochemical sources, a process associated with negative environmental impacts. In recent decades, efforts to develop clean...

Association of plasma growth differentiation factor-15 with the frailty phenotype – Evidence from the COGFRAIL study

Background Growth differentiation factor-15 (GDF-15) has been consistently associated with physical frailty. However, it remains unclear whether GDF-15 further discriminates adverse outcomes among older adults who are already physically and cognitively impaired. Objectives To eva...

Stereoselective trans -1,4 Polymerization of Isoprene and β -Myrcene Mediated by Iron Complexes Bearing 1,1-Diaryl- N -(quinolin-8-yl)methanimine Ligands

Abstract Although iron has emerged as an earth-abundant alternative for 1,3-diene coordinative polymerization, stereoselective iron systems remain uncommon and are often associated with limited catalytic activity. Here, we report three iron(II) complexes supported by 1,1-diaryl-N...

Systematic detection of magnetic fields in the cores of red giants

In this presentation, we present the scientific context behind the detection of core magnetic fields in red giants. These fields are one of the most promising phenomena to explain the observed rotation rates in stellar interiors, which cannot be explained by a simple conservation...

Direct time-domain eduction of acoustic liner impedance in turbulent grazing flows

Acoustic liners are passive sound-absorbing materials widely used in engineering applications and are commonly characterised by their acoustic impedance. In the presence of high sound pressure levels or grazing flows, the impedance is modified by local nonlinear effects. Conventi...

EXPRESS: Keyboard Layout Facilitates Anagram Solving: Evidence for Embodied Effects of Typewriting.

Motor experience related to writing influences reading performance, from letter recognition to word recognition. In our study, we tested the hypothesis that knowledge of the keyboard layout associated to typing promotes the retrieval of the order of the sequence of letters compos...

Laser Doppler Velocimetry Measurements of Acoustic–Turbulent Flow Interaction over Liner

The interaction between a grazing turbulent boundary layer at Mach 0.3 and tonal acoustic waves with an amplitude equal to 145 dB over a single-degree-of-freedom acoustic liner is investigated experimentally using laser Doppler velocimetry. Streamwise and wall-normal velocity pro...

NucGen3D: A synthetic framework for large-scale 3D nuclear segmentation with open-source training data and models

A bstract Robust nuclear segmentation in 3D microscopy images is a critical yet unresolved challenge in quantitative cell biology, hindered by the scarcity and variability of annotated volumetric datasets. Because such data are difficult to obtain, most state-of-the-art approache...

Oscillatory Traveling Waves During Visual Entrainment in Autistic and Non-Autistic Adults

Neural oscillations and traveling waves play a crucial role in cognition. In scalp electroencephalography (EEG), waves typically travel along the anterior-posterior axis: forward waves (occipital-to-frontal) predominate during sensory stimulation, while backward waves (frontal-to...
