Competition and soil conditions limit the growth of High Arctic non‐native plants

Non-native vascular plant species in the High Arctic are currently restricted mainly to settlements and other anthropogenically disturbed areas. The reasons for this remain unclear, but climate or dispersal do not appear to be the main limiting factors. Instead, biotic interactio...

Radiocarbon dating of mortars: A case study from ancient village Dūré

Abstract The absolute chronology of historical structures in regions with limited documentary evidence or organic remains presents a significant challenge for archaeologists and historians. Radiocarbon dating of anthropogenic carbonates, such as mortar binders, offers a potential...

Red Light‐Gated Charge Transfer Enables Trace Oxygen Response in Dye‐Sensitized TiO 2 –Carbon Nanotube Hybrids

ABSTRACT Light offers a powerful means of activating materials with spatial and temporal precision. However, translating excited‐state processes into chemically responsive electronic function in conductive solids remains challenging, particularly under low‐energy red illumination...

Two millennia of Caspian Sea level change and Hyrcanian forest dynamics: A multi-proxy record from the Anzali Lagoon, northern Iran

A multi-proxy study of a 5-m-long sediment core from the Anzali Lagoon (southwest Caspian coasts) was conducted to reconstruct Caspian Sea level fluctuations and concurrent vegetation history in the Hyrcanian forests over the past two millennia. The record reveals several major t...

Advancing chemical reaction prediction in data-scarce drug discovery with active and geometric deep learning

Abstract The success of generative molecular design depends on the synthetic accessibility of the molecules it creates. While computational models can help predict chemical reactions, their current effectiveness is limited by a lack of reference data and the difficulty of accurat...

A Transnasal Endoscope for Robotically Assisted Gastroscopy

A robotic transnasal endoscope (TNE) is developed to improve minimally invasive access to the upper gastrointestinal (GI) tract and support early cancer detection. The device is 4.25 mm in diameter and is designed to be compatible with transnasal access while preserving diagnosti...

Integrating hyporheic exchanges into salmonid spawning habitat models—A proof of concept focusing on Atlantic Salmon in Québec, Canada

Abstract Objective Most salmonids use pool–riffle transitions for spawning. The biological explanation appears to be associated with bedform-induced hyporheic exchanges. Despite this apparent link, spawning habitat models still rely on depth, velocity, and bed material grain size...

Antenna subtraction at NNLO for heavy quark pair production at hadron colliders: the non-diagonal channels

A bstract We present the calculation involving the qq , qq ′ and qg partonic channels contributing to heavy-quark pair production at hadron colliders through next-to-next-to-leading order in QCD using the antenna subtraction formalism. The calculation is performed in full colour...

The influence of lakes and reservoirs on estimated flood peaks at hourly vs. daily timescale in the Alps

Abstract. Water bodies such as lakes and reservoirs can play a crucial role in reducing flood peaks both on daily and hourly timescales. While the effect of water bodies on flood peaks at different time resolutions has been demonstrated in the past, it remains unclear how they af...

Reconciling intrinsic and ecosystem water-use efficiency reveals physiological mechanisms underlying carbon-water coupling across biological scales

Understanding how carbon-water coupling scales from leaves to ecosystems remains a major challenge because water-use efficiency (WUE) metrics integrate physiological, hydrological, and ecological processes. We integrated tree-ring width, triple stable isotopes (δ13C, δ18O and δ2H...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

Experimental study of a ten sodium heat pipe bundle array with various failure modes

Alkali metal heat pipes are key components for high-temperature heat removal in microreactors, where multiple heat pipes are embedded directly within the reactor core. Their collective thermal behavior, including interactions under off-normal conditions, remains insufficiently ch...

Determination of inter-individual differences in humeral head centre translations in subjects with healthy shoulders

Abstract The aims of this study were to (i) quantify glenohumeral (GH) joint translations in healthy shoulders, (ii) assess subject-specific variability in GH translations, (iii) determine whether bony joint geometry (glenoid height, width, retroversion, inclination, GH aspherici...

PIEZO1 Is a Contextual Mechanosensor and Its Depletion in Scx‐Lineage Cells Accelerates Structural and Functional Recovery

ABSTRACT Previous work has identified PIEZO1 as an important mechanosensor in homeostatic tendon, where it detects mechanical overload and regulates tissue adaptation. Here, we investigated the consequences of PIEZO1 depletion during tendon healing using a full‐thickness central‐...

Multi-factor assessment of future climate hazards to apple production across Switzerland’s growing regions

Abstract Apple production is likely to face increased climate hazards in the future resulting from climate change. The magnitude and relative importance of different climate hazards remain unclear, especially when considering multiple emissions scenarios. Here, we perform a multi...

Benchmarking a new urban scheme in the ORCHIDEE 2.2 land surface model

Urban areas change natural surface energy and water balances, yet some land surface models still represent cities as natural surfaces. In this study, we present the development of a one-tile urban scheme for the ORCHIDEE land surface model, designed to improve the representation...

Associations between urban form and urban multifunctionality: a comparative study

Abstract Cities are complex and dynamic systems that integrate social, ecological, and infrastructure domains. This study investigates and quantifies how urban forms are associated with multiple urban functions across these domains, and how these associations combine into positiv...

Remote sensing and deep learning for standing dead-tree detection and mapping: a review of advances, challenges, and future directions

Standing dead trees are visible indicators of tree mortality and an important transitional component linking forest disturbance to future lying deadwood, habitat availability, and carbon storage. As drought, insect outbreaks, pathogens, and climate extremes intensify tree mortali...

Effect of Water Stress and Cabbage Aphid Feeding on Ethiopian Mustard Brassica carinata Physiology

Water deficit represents a critical abiotic constraint that impairs fundamental physiological processes in plants.Water deficit as a single stressor influences aphid's performance indirectly through changes in plant physiology.The present study was conducted in a greenhouse to in...

Rod photoreceptors have a dual dependency on both aerobic glycolysis and OXPHOS and diverge metabolically from other retinal neurons

The retina metabolizes glucose into lactate, a hallmark of aerobic glycolysis known as the Warburg effect. Although evidence points to rod photoreceptors as the primary source of aerobic glycolysis, a comparison of the energy metabolism in different retinal neurons has yet to be...
