Quantum metrology of spin sensing with free space electrons

Abstract Recent advances in transmission electron microscopy (TEM) have opened the path toward spin resonance spectroscopy with single-spin sensitivity. To assess this potential, we investigate the quantum precision limits for sensing magnetic moments with free-electron probes. U...

Nothing new to see here?! A critical (visual) discourse analysis of climate (im)mobility in IOM documents

This paper revisits critical climate mobility literature that explores the role of images and visual materials within policy briefs and papers, published about a decade ago, to contrast those findings with present-day policy documents. Based on a discourse analysis of 10 recent I...

Investigation into the transforming mechanism from flash-to-conventional drought in different soil moisture layers in a highly climate-diverse basin

Study region The Indus Basin, a highly diverse climate basin in South Asia. Study focus The transformation from flash drought to conventional drought (FD-CD) poses significant challenges to drought risk and management systems, necessitating a comprehensive assessment of the dynam...

Technical note: A physically based correction of WRF temperature using atmospheric lapse rates for high-resolution hydrological simulations in a glacierized catchment

Abstract. High-elevation alpine catchments are particularly affected by the global rise in temperature. Understanding the drivers of climate-induced changes in the hydrological response of these catchments in the past is relevant for developing future adaptation strategies for wa...

Episodic isolation of the Arctic Mediterranean from the North Atlantic during late Pleistocene glacials

Abstract It has been proposed that the Arctic Ocean and Nordic Seas (together referred to as the “Arctic Mediterranean” - AM) were not only covered by a thick ice shelf during past Pleistocene glaciations 1 but also filled with freshwater 2 implying a disconnection from the North...

High-resolution late Quaternary Indo-Pacific Warm Pool benthic δ18O stratigraphy for evaluating the precession timing of the marine Asian monsoons

The timing of Quaternary precession-scale (23 kyr) monsoon variations across the Asia-Australia and the Indo-Pacific regions remains highly debated. The Asian monsoon phase differences of approximately 5 ka reported between a suite of marine sedimentary and speleothem proxy recor...

Governmentality, Populism, and New Right Thought: Disaggregating Far-Right Authoritarian Mainstreaming

Drawing on a genealogical analysis of governmentality and counter-conduct, this contribution offers a novel perspective on the contemporary political and ideological struggles that are driven by the far right. Highlighting key insights produced in this special issue, this article...

“ Women are more encouraged to apply ”: The disconnect between the gender equality agenda and young women’s employment practices in urban Sierra Leone

In recent decades, increasing female labor market participation has emerged as a key political priority both nationally and internationally. However, existing studies reveal that its increase alone is insufficient to tackle deeply rooted gender-based inequalities, as a substantia...

Safeguarding global terrestrial vertebrate species from future sea-level rise

Sea-level rise (SLR) threatens terrestrial biodiversity, yet its spatiotemporal and species-specific impacts remain unclear. Integrating relative SLR projections across five Shared Socioeconomic Pathways (SSPs) with Area of Habitat (AOH) maps for 34,120 terrestrial vertebrate spe...

Impacts of simulated coastal ocean alkalinity enhancement on the seasonal carbon cycle in European waters under a low- and a high-emission scenario

One potentially scalable method to remove CO 2 from the air is ocean alkalinity enhancement (OAE), which works to lower the ocean's CO 2 partial pressure ( p CO 2 ) and accelerate CO 2 sequestration and durable storage. This study explores how OAE might affect the seasonal carbon...

Optimizing nanoLC-TIMS-TOF and lipidomics sample preparation for low volume of plasma

Abstract Lipidomics provides critical insights into disease mechanisms, biomarker discovery, and precision medicine, but conventional LC-MS workflows often require sample volumes that limit their application in minimally invasive studies. Here, we evaluated a nanoflow liquid chro...

Stages of turbulence generation and decay in a T-shaped mixer

The T-shaped mixer is widely used in fundamental studies of chemical engineering. Its transitional regime is well understood, whereas the turbulent dynamics has received scarce attention so far. Here, we perform direct numerical simulations of the turbulent regime for Reynolds nu...

Climate Knowledge in Large Language Models

Abstract Large language models (LLMs) are increasingly deployed for climate-related applications, where understanding internal climatological knowledge is important for assessing their reliability. Despite growing adoption, the capacity of LLMs to recall climate normals from para...

Hierarchical quasiparticle dynamics in antiferromagnets revealed by time- and momentum-resolved X-ray scattering

Abstract Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations —magnons— mediate these flows in ultrafast magnetism. Yet momentum-resolved access to low-energy magnons governing the microsc...

The relationship between health literacy and active and successful aging: a cross-sectional study of active aging service center

Abstract Background While successful aging focuses on physical health and disease prevention, active aging offers a broader framework encompassing social participation and security. Health literacy is considered a vital tool in achieving these outcomes, yet its specific impact on...

Volcanic stratigraphy offshore East Montserrat: Selective preservation and subaqueous remobilisation in marine records

Abstract In tectonically active regions, volcanic eruptions generate large volumes of material that are transported offshore through processes such as pyroclastic density currents, turbidity currents, and secondary sediment remobilisation. These deposits form key stratigraphic ma...

Coral-associated denitrification is seasonally variable and species-specific

Abstract Nitrogen (N) plays a critical role in coral growth, but maintaining an N-limited state is essential for coral-algal symbiosis stability. Coral-associated denitrifiers may help regulate excess N, though denitrification in corals remains poorly quantified. To better unders...

Comorbidities in individuals with intellectual disabilities with and without hearing loss: a prospective cohort study

Abstract Background Both intellectual disability (ID) and hearing loss (HL) are associated with a high prevalence of certain comorbidities. However, a combined analysis and overview classified according to the International Classification of Diseases, 11th Revision (ICD-11), is l...

Consistency between zonal mean stratospheric and total column ozone trends (2000–2024)

This study presents an updated assessment of stratospheric and total column ozone trends over the 2000–2024 period using six merged limb-profile datasets and six merged total ozone datasets. Long-term changes were quantified using a multiple linear regression framework that accou...
