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...

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...

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...
