Learning Sequences and Events in Individual, Pair and Group Data-Driven Learning

Abstract Previous research has shown that the learning process in data-driven learning (DDL) is cyclical, iterative, and non-linear, even when tasks are designed around seemingly linear pedagogical frameworks such as Illustration–Interaction–Intervention–Induction (Carter, Ronald...

Sensitivity of the Bootstrap sea ice concentration algorithm to surface parameters in the Antarctic marginal ice zone using passive microwave retrievals

Abstract. Changes in sea ice concentration (SIC) and derived sea ice extent have been monitored using microwave radiometers since the late 1970s, providing information about the polar response to climate change, making SIC an invaluable variable for numerical models. Antarctic se...

Rocks out, waste in: A double penalty in gravel-rich river valleys?

Construction and Demolition (C&D) waste is the largest solid waste stream in France, yet circular economy (CE) research on this sector tends to privilege technical and quantitative framings over its socio-economic and governance dimensions. This article examines the implementatio...

Ultra-compact plasma photocathode in a hybrid wakefield accelerator

Abstract Plasma-based particle accelerators, realized by driving plasma waves with either an intense laser pulse or particle beam, offer accelerating fields orders of magnitude higher than conventional accelerators. This enables sources of highly relativistic electron beams with...

Beyond Weight Loss: A Comprehensive Review of Integrated Pharmacotherapy and Metabolic Bariatric Surgery in Endometrial Cancer Care

Backgroundand Objectives: Endometrial cancer ranks among the most prevalent gynecologic malignancies in high-income countries, with increasing incidence and mortality driven by the global obesity epidemic. Evidence suggests that women with early-stage disease face a greater risk...

Conformal Assembly of Platinum on Self-Standing Structured Cathodes for PEMFCs

Abstract A self-standing cathode architecture for proton exchange membrane fuel cells was developed. A conformal, thin layer of platinum was electrodeposited on a self-standing carbon-fiber-based structured support in the form of an extended-surface particulate film. Abundant gra...

Forgotten reservoirs: an attempt to revive field research on rodent malaria parasites in their main natural host, the thicket rat Grammomys poensis (formerly Thamnomys rutilans)

<title>Abstract</title> Rodent malaria parasites have long served as essential experimental models for understanding human malaria, yet little is known about their ecology and evolution in the wild. The thicket rat <italic>Grammomys poensis</italic> (formerly <italic>Thamnomys ru...

Ediacaran coupling of climate and biosphere dynamics

Climate change is demonstrably linked to radiations, extinctions, and turnovers in the biosphere throughout the Phanerozoic (538.8 Ma to present). Here, we suggest this connection existed as early as the late Ediacaran (ca. 579−538.8 Ma), the first interval in Earth’s history to...

What does a territory tell? Co-constructing heritage through complex social values in inner contexts

Italian inner areas are increasingly affected by depopulation, demographic ageing, and territorial fragmentation. In these contexts, cultural heritage is frequently mobilised as a resource for local development and regeneration. While heritage studies have widely recognised that...

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...

Tail Modulo Async-Await

This article extends tail-call optimisation by applying it to asynchronous calls. We first introduce TMA, a novel code transformation for asynchronous tail recursive functions that prevents the creation of unnecessary tasks. We then show how to combine TMA with the existing TMC o...

Health and nutrition returns to clean cooking fuel access across the rural-urban divide

Access to clean cooking fuels is central to advancing health, equity, and environmental sustainability worldwide. However, despite sustained policy efforts, a substantial share of households, especially in developing countries, still rely on polluting fuels, with adverse effects...

HighlyTransparent Layer-by-Layer Nanoassembled MulticomponentFilms of TiO2 and Graphene for Increased PhotocatalyticPerformance

Abstract Here, we report novel highly transparent and photoactive multicomponent films for enhanced photocatalytic applications. Some films are based on intimately interfaced TiO2 nanoparticles and few-layer graphene (FLG) assembled through an environmentally friendly aqueous lay...

Longitudinal progression, metrics, age-dependence, and modifiers of ataxia severity in SCA27B: a multicentre study of 219 patients

Background Spinocerebellar Ataxia 27B (SCA27B) is a novel, frequent and likely treatable late-onset autosomal-dominant ataxia caused by GAA repeat-expansions in FGF14 . For understanding disease evolution and imminent trial planning, metrics of the most widely used clinical outco...

Toward Climate-Responsive Ocean–Terrestrial Biorefineries: Integrating Algae and Agricultural Residues for Circular Bioeconomies

Abstract This paper evaluates climate-responsive biorefineries that integrate pelagic Sargassum with agricultural residues to advance circular bioeconomies. Building on scientific priorities emphasized at the 2025 One Ocean Science Congress and emerging policy directions from the...

The Intergenerational Correlation of Subjective Well Being

There are many estimates of the intergenerational transmission of income and education, even though these may be considered as only partial measures of individual welfare. We here analyze long-running UK panel data and directly consider the intergenerational transmission of two w...

Influenceof Anti-Agglomerants and Water Cut on FlowAssurance and CO2 Capture in a Model Water-in-Oil Systemfor Maritime Applications

Abstract This study investigated the effects of antiagglomerant (AA) concentration and water cut (WC) on flow assurance within a gas hydrate-based CO2 capture and transport using a model water-in-oil (W/O) system for maritime applications. Phase equilibrium measurements revealed...

Will work for sardines: 20 years of animal-borne ocean observing by Australia’s Integrated Marine Observing System (IMOS) Animal Tagging Facility

The world’s ocean stores ~90% of the excess heat generated by anthropogenic global warming, making sustained ocean observations essential for understanding physical, biological and climate processes. Here, we describe how the Integrated Marine Observing System (IMOS) Animal Taggi...

Occurrence and controls of ~ 1 Hz waves in Mercury’s magnetosphere: insights from MESSENGER observations

<title>Abstract</title> Mercury’s magnetosphere is highly dynamic, with processes occurring on much shorter spatial and temporal scales than at Earth due to its weak magnetic field and proximity to the Sun. Wave-driven transport of energy and momentum is a key manifestation of th...

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...
