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...

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...

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...

Unleash $Q$! cohomology, localization, and interpolation in Parisi-Sourlas supersymmetry

Parisi—Sourlas supersymmetric models are known to undergo dimensional reduction; that is, their physics is captured by models in two fewer dimensions. In this work, we revisit dimensional reduction, providing new arguments and reformulating existing proofs in terms of the cohomol...

Unraveling HBV Life Cycle by Fluorescent Microscopy Imaging

The hepatitis B virus (HBV) is a worldwide hepatotropic virus despite the availability of a highly effective vaccine. Currently, the most efficacious treatment against HBV infection is the use of interferon and nucleos(t)ide analogs, which effectively suppress viral replication b...

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures

We developed a high-content screening to investigate how Alzheimer’s disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently d...

Glimpse into the past: Analyses of the middle and inner ear of extinct rodents (Eusciurida; Rodentia; Mammalia) with implications for their locomotory behaviour

Abstract Rodentia is the most diverse and species-rich group of mammals, inhabiting almost all regions and ecosystems on earth. One of the most specialised subgroups is the Eusciurida, composed of Sciuridae, Gliridae, and Aplodontia rufa , and characterised by arboreal, fossorial...

Neutron elastic scattering at $$\varvec{30.8}$$ MeV on $$\varvec{^{\text {nat}}\textrm{Ce}}$$

Abstract Elastic scattering of fast neutrons at an incident energy of 30.8 MeV on a natural cerium target was measured during an experiment conducted at the Neutrons For Science facility at GANIL-SPIRAL2. This is the first measurement on cerium using incident neutron energy above...

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,...

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...

Trace Elements in Total Atmospheric Deposition Directly Measured Over the Caribbean Region: Natural Versus Anthropogenic Sources and Geographic Origin

Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set reco...

Yu-Shiba-Rusinov-assisted Andreev transport in a molecular junction between superconductors

Magnetic impurities in superconductors host Yu-Shiba-Rusinov (YSR) bound states, whereas weak superconducting junctions sustain subharmonic charge transport through multiple Andreev reflections (MAR). We explore these phenomena using a molecular-scale junction created by placing...

Genetic variability and population structure within the Anopheles tessellatus complex (Theobald, 1901) in Indonesia using ITS2 nuclear and COI, COII mitochondrial sequences

Abstract Some Anopheles species that act as malaria vectors are members of species complexes, a concept whereby sibling species cannot be differentiated solely on the basis of morphological characters. Therefore, species complexes represent a major problem in malaria vector contr...

Mapping structural heterogeneity in three-dimensional biophotonic gyroid networks using position-resolved small-angle X-ray scattering

Abstract The wings of select Papilionid and Lycaenid butterflies contain a three-dimensional gyroid network of a solid cuticle phase in air. In butterfly scales, gyroid networks are optically interesting, as they create the green colour observed in the wings of these butterflies....

Contrasting seasonal roles of external forcing and internal variability in East Asian temperature

How to reliably separate external forcing (EXF) and internal variability (IV) components of regional temperature variation is of critical importance in East Asia. We implement here an EOF-based semi-empirical framework to avoid spurious teleconnections often present with conventi...

Critical neuronal avalanches arise from excitation-inhibition balanced spontaneous activity

Neuronal avalanches are sequences of neural activations exhibiting scale-invariant statistics, indicative of critical dynamics. Theoretical studies proposed that the balance between excitation (E) and inhibition (I), along with neuromodulation, are key factors influencing this cr...

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...

Morphological and Size‐Dependent Enrichment of Endotoxins in Coastal Spray Aerosols: Implications for Regional Respiratory Health Risks

Abstract Sea spray aerosols (SSA) transport bioactive substances that affect the Earth's environmental and climate system. We investigated the enrichment of endotoxins (LPS), characterized their influence on the SSA morphologies, and evaluated the respiratory tract deposition. LP...

Questioning the Evidence for Host-Symbiont Codiversification in Mycorrhizal Symbioses

Abstract The vast majority of plants form mycorrhizal symbioses. The ecological importance of these mutualistic interactions has sparked interest in their long evolutionary history. By examining interaction networks and phylogenetic trees, several studies have suggested that plan...
