A New Era for Navigation with LEOPNT in Europe: The Celeste IOD Mission and Recent Advances in Safran’s Skydel Simulator

This paper aims to provide an accessible and pedagogically-oriented overview of recent European advances in LEO-PNT by focusing on three complementary aspects: - The development of ESA' In-Orbit Demonstrator (IOD) mission, Celeste, and the Navigation Innovation and Support Progra...

A New Characterization of the Wulff Shape

We prove a new charcaterization of the Wulff shape in termes of higher order anisotropic mean curvatures. Namely, if a closed, connnected and oriented hypersurface of the Euclidean space has a constant higher order anisotropic mean curvature H F r and another one H F s almost con...

GRAPHERGIA D4.3: Preliminary Energy harvesting system

The GRAPHEGIA project was launched on the 1st of October, 2023, for 3,5 years, and it is a research and innovation project co-funded by the European Union. It uses the graphene-enabled innovation for novel and sustainable energy harvesting and storage systems. Deliverable 4.3 “Pr...

The development of maritime autonomous surface ships (MASS) from seafarers’ perspective: operational, spatial, and labour implications

Abstract The development of maritime autonomous surface ships (MASS) is increasingly considered as a solution to labour shortages, cost pressures, and safety concerns in maritime transport. While much of the discussion centres on technical feasibility and regulatory challenges, t...

Sequential Bayesian identification using multi-fidelity Gaussian process surrogates: Application to an inverse transient thermal problem

A sequential Bayesian inversion algorithm is proposed for the estimation of unknown parameters in complex physical models, particularly when dealing with expensive simulations, a frequent challenge in industrial applications. The approach aims to accurately infer the posterior di...

Forest stand descriptions from the French Soil Quality Monitoring Network: repeated surveys (2006–2024) and documented silvicultural management

Abstract Key message A new database of forest stand characteristics from forest sites (583 sites) within the French Soil Quality Monitoring Network (RMQS) is now available. Covering two campaigns (2006–2007 and 2024), it includes descriptive stand-level data (forest structure, de...

Soil response along the pile shaft of a shared anchor subjected to multi-directional lateral loading

Shared pile anchoring enables multiple floating wind turbines to be secured to a single foundation, offering significant potential to reduce mooring costs and environmental impact. However, this concept introduces complex multi-directional cyclic loading on anchor piles, which re...

Addressing anthropogenic noise and electrical anisotropy hints in magnetotelluric data from the Annecy area (French Pre-Alps)

The magnetotelluric (MT) method is a widely used tool for geothermal reservoir exploration due to its capability of imaging fluids in the Earth’s crust. However, in urbanised environments, its application is often challenged by anthropogenic noise and low signal-to-noise ratios....

Infrastructuring short food supply chains: how intermediaries bind rules, norms and values

Food supply chains are crucial for food security and socio-economic development, yet their length concentrates value away from producers and consumers disproportionate resources. As the COVID-19 pandemic and the wars in Ukraine and Iran exposed, overreliance on long chains produc...

Single-photon double ionization of ozone: experiment and theory

Abstract The triatomic molecule ozone (O3) is of outmost physical and chemical importance in the atmospheres of our Earth and other planets. Beyond its environmental significance, a detailed understanding of the electronic structure and ionization dynamics of ozone is essential f...

Poromechanical toughening in tensile fracture of saturated solids

<title>Abstract</title> Fracture in fluid-saturated porous solids is governed not only by solid mechanics but also by fluid flow within the pore space. In systems ranging from geomaterials to biological tissues, deformation in the near-tip region perturbs pore pressure and thereb...

Hematological profiles and preventive-practice characteristics among patients with podoconiosis: A case-control study in Musanze District, Rwanda

Background Podoconiosis is a chronic, disfiguring, non-filarial form of lymphedema caused by prolonged barefoot exposure to irritant soil. An estimated four million people are affected globally, with cases documented in more than 32 countries, 18 of which are in Africa. In Rwanda...

Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ 56 Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Gu...

Optimal Vaccination Strategies for a Heterogeneous SIS Model

Abstract. We study in a general mathematical framework the optimal allocation of vaccine in an heterogeneous population. We cast the problem of optimal vaccination as a biobjective minimization problem [Formula: see text], where [Formula: see text] and [Formula: see text] stand,...

Energy de-escalation as a pathway to sufficiency: perspectives from infrastructures in a university campus

This research examines energy sufficiency in the built environment, understood as the reduction of energy consumption through changes in social practices and infrastructures, among other factors, as a key objective for remaining within planetary boundaries.We draw insights from s...

Drainage divide dynamics modulated by erosion-driven landscape adjustment in a low-deformation setting

The Vosges Mountains (northeast France) are a mid-altitude mountain range with peaks reaching ∼1500 m a.s.l., in a low-deformation setting. Despite this, they maintain significant topographic relief (up to ∼1000 m), characterized by deeply incised valleys and broad, rounded uplan...

Very‐Long‐Period Seismic Signals During Lateral Dike Propagation at Piton de La Fournaise Volcano

Abstract We report a previously undocumented sequence of very long period (VLP) signals preceding the September 2022 eruption at Piton de la Fournaise. These events occurred during lateral magma propagation and exhibit quasi‐periodic sawtooth‐shaped displacement transients. Seism...

Individualized statin associated type 2 diabetes risk estimation with a deep causal model

Statin therapy reduces cardiovascular risk, but recorded statin exposure is associated with subsequent type 2 diabetes (T2D) in some populations. Individualized risk estimation and separation of low-density lipoprotein cholesterol (LDL-C)-mediated from non-LDL components remain c...
