Adaptive behavioural strategies promote species persistence in niche-constrained ecological communities

Abstract Species persistence in ecosystems results from the interplay between ecological interactions and behavioural strategies. Classical niche theory explains how resource overlap determines the strength of interactions, while evolutionary game theory (EGT) describes how coope...

A global dataset of forest disturbance regimes derived from satellite biomass observations

Abstract. Forests play a central role in the global carbon cycle by serving as critical carbon sinks for atmospheric CO2. Yet, the stability and continued capacity of these sinks are increasingly threatened by a growing number of disturbances. Accurately representing the stochast...

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...

Unitary representations and von Neumann’s continuous geometries

We prove that the unit group of a nondiscrete irreducible, continuous ring, in the sense of John von Neumann, does not admit any nontrivial unitary representation continuous with respect to the strong operator topology.

Mucus transport in the olfactory cleft is significantly slower than in the nasal respiratory mucosa.

Intranasal mucociliary transport has been conventionally described as moving, essentially, in an anterior-to-posterior direction along the ciliated respiratory mucosa (RM). This mechanism is essential for clearing inhaled particles and pathogens and may be impaired in individuals...

Holocene hydroclimatic variability and multi-frequency analyses at Lake Sidi Ali (Morocco)

Abstract. The North African desert margin is considered one of the most sensitive areas to future climate changes, yet the periodicities, coupling mechanisms and external forcing of Holocene environmental variability remain poorly understood. To investigate millennial- to centenn...

Electron-RichAcetylenic Nanostructures with In Situ Chelated UltrafinePalladium Nanoclusters for EfficientLiquid-Phase Reaction Catalyst

Abstract The development of uniformly distributed ultrafine metallic nanoclusters for advanced catalysts has attracted significant interest. However, synthesizing supports with specific electronic environments and well-defined pores to prevent aggregation remains challenging. Her...

On the compatibility of LaB6 and iodine in planar and hollow cathodes

Abstract Iodine is increasingly considered a viable alternative to noble gases for electric propulsion systems, particularly due to its high storage density and non-pressurized form. While various thruster types have been successfully tested with iodine as a propellant, the compa...

External validation of a top-ranked model from the RSNA pulmonary embolism detection challenge: assessment of generalizability

Abstract To externally validate the RSNA 2020 challenge 2 nd -place deep-learning (DL) algorithm for detecting pulmonary embolism (PE) on computed tomography pulmonary angiography (CTPA) scans with additional focus on subsegmental-only PEs (SSPE). Between 2015 and 2022 1,038 CTPA...

Enhanced Growthin Sb2Te3/SnSe2 Multilayered AtomicLayer Deposition: Nucleation and NanostructureModification

Abstract Multilayer thin film structuring offers a versatile strategy to tailor nanostructures through interface engineering. Atomic layer deposition (ALD) provides precise control of composition and structure via supercycle approaches that enable the multiple metal species intro...

Detection of Kankra (Bruguiera gymnorhiza) tree expansion in the northern Sundarbans

Mangroves are vulnerable to environmental changes, which can shift in the dominant species composition across ecological zones. This research aims to develop an object-based image analysis (OBIA) methodology combining Landsat imagery with very high spatial resolution reference im...

Climate Impact Robust Design Optimization for Turbofan Aircraft Engine

Abstract This paper investigates robust design optimization of turbofan engines to minimize climate impact while accounting for significant uncertainties in climate models based on performance calculations. By incorporating engine performance, flight mission, emission, and linear...

A Flow-Through Multi-Wavelength Sensor with Machine-Learning Calibration for Real-Time Monitoring of Microalgae Cultivation Processes

Acquiring real-time biological data is essential for effective control of microalgae cultivation processes, yet routine monitoring still depended on laborious offline analyses that relied on time-consuming wet-chemical techniques. This study introduces a flow-through, multi-wavel...

Thyroid disorders, thyroid autoimmunity, and anxiety—a systematic review and meta-analysis of population-based studies

Objectives Previous studies, largely based on case–control samples, have suggested that hypothyroidism, hyperthyroidism, and thyroid autoimmunity may be associated with an increased risk of anxiety. However, whether a true association exists remains unclear, as population-based s...

Quantifying the Interplay Between PRAME Expression and Classical Morphology: A Multivariable Analysis of 954 Suspected Melanocytic Lesions

The integration of immunohistochemical biomarkers like PRAME (Preferentially Expressed Antigen in Melanoma) into the histomorphological assessment of melanocytic lesions is gaining prominence. While PRAME’s diagnostic value is widely recognized, its independent weight compared di...
