JuRa: The Juventas Radar on Hera Mission to Probe Internal Structure of Didymos and Dimorphos Asteroids

Abstract JuRa, the Juventas Radar, is the sounding radar of the Hera/ESA mission on cruise to the asteroid Didymos and its moon, Dimorphos. In 2027, it will, for the first time, do direct observation of the internal structure of an asteroid for the benefit of both science and pla...

Rapid data quality investigations of gravitational-wave events with the Data Quality Report Builder toolkit

Abstract We present the Data Quality Report Builder toolkit, DQRbuild, a suite of data quality tools that have been developed to vet gravitational-wave events in preparation for the fourth LIGO-Virgo-KAGRA observing run. We explain the main functionality and the many scientific t...

Molecular Hybridization-Guided Design and Synthesis of Novel Pyrazolylidene–Thiazolopyrimidine Derivatives

Abstract The development of hybrid heterocyclic scaffolds represents an effective strategy for expanding the structural diversity of heterocyclic compounds. Herein, we report the synthesis of a new series of pyrazolylidene–thiazolopyrimidine hybrids through a concise and efficien...

Underground Signals: The Ecological Power of Root Volatiles

Root volatiles mediate diverse belowground interactions among plants, microbes, and invertebrates, but biological and environmental conditions strongly influence their production, movement, perception, and ecological effects. This review synthesizes current knowledge through an i...

Probabilistic Characterisation of Service Lifetime of Ageing Infrastructures

Abstract Ageing infrastructures are increasingly exposed to deterioration mechanisms related to time, environmental conditions, and increasing operational demands. Ensuring their safety and serviceability therefore requires continuous monitoring and reliable methods to assess the...

Biofunctionalized hierarchical mesoporous zeolite 5A–maghemite hybrids for Cd(II) adsorption: Surface chemistry and interfacial binding mechanisms

Cadmium contamination of water requires adsorbents that combine high removal efficiency, rapid kinetics, and easy recovery after treatment. In this work, two families of biofunctional magnetic nanohybrids, MCZO and MCZ1, were prepared by combining zeolite 5A with γ-Fe 2 O 3 nanop...

Climate mitigation contributes more to population persistence than evolutionary adaptation in a long-lived seabird

Evolutionary rescue–the process by which adaptive evolution prevents population extinction following environmental deterioration –is frequently proposed as a buffer against biodiversity loss under climate change, yet its capacity to alter future population trajectories is rarely...

Mont Blanc ice core: δ15N of Ammonium

Dataset to interpret the δ15N(NH4+) in a Mont Blanc ice core. The document includes high resolution measurements and decadal averages of the CDD16 ice core. High-resolution measurements are in depth (m) or age (a CE). Decadal averages are mass weighted means. The long term values...

Investigating tunnel seepage erosion and induced structural mechanical response using CFD-DEM-FEM method

Seepage erosion, induced by groundwater infiltrating surrounding soils through cracks between tunnel segments, poses a significant threat to the long-term stability of underground tunnels. However, the evolution of erosion and its influence on tunnel mechanical behavior remain in...

From online traces to upstream surveillance: Large language models uncover the hidden status of non-native freshwater apex predators in China

Biological invasions are often recognised only after ecological damage has become visible in the wild, even though the human-mediated processes that drive introductions may already be underway through private rearing, trade, and release. This gap in upstream surveillance is espec...

Microsecond-pulsed nanocalorimetry: a scalable approach for ultrasensitive heat capacity measurements

Abstract We introduce a nanocalorimetric technique based on microsecond-pulsed heating (µs-PHnC) that enables high-sensitivity, quasi-isothermal heat capacity measurements on nanoscale samples. Such resolution is critical for exploring thermodynamic signatures in low-dimensional...

Complement C3a receptor expression is associated with distinct immune microenvironmental profiles in clear cell renal cell carcinoma

The complement receptor C3aR has emerged as an important regulator of tumor–immune interactions in several solid cancers. However, its cellular distribution and relationship with the immune microenvironment in clear cell renal cell carcinoma (ccRCC) remain poorly understood. Here...

Time-varying formation control via output feedback for multi-agent systems over switching networks with hidden Markov dynamics

This paper addresses time-varying formation control for a class of multi-agent systems. In particular, distributed static output control laws are designed for homogeneous discrete-time linear multi-agent systems whose network topologies switch according to an unknown Markov chain...

Carbon solubility and liquid–liquid immiscibility in Fe–C–S ternary system up to 6 GPa: implications for the core of small planetary bodies

Abstract High-pressure, high-temperature experiments were conducted in a multi-anvil press using seven different starting compositions to investigate the phase relations of Fe–C–S liquids at pressures up to 6 GPa and temperatures up to 2000 K. Quenched samples revealed immiscible...

3D thermal modeling of Lascaux Cave: Dynamics of air circulation and implications for its microclimate

Understanding the thermal dynamics of painted caves, such as the Lascaux Cave, is essential for predicting and preventing deterioration of walls and artworks, particularly through processes such as condensation. As a first step, heat conduction within the surrounding rock mass wa...

On Hyperbolic Approximations for a Class of Dispersive and Diffusive-Dispersive Equations

Abstract We introduce novel approximate systems for dispersive and diffusive-dispersive equations with nonlinear fluxes. For purely dispersive equations, we construct a first-order, strictly hyperbolic approximation. Local well-posedness of smooth solutions is achieved by constru...

A predictive coding framework for safe and versatile control of supernumerary robotic limbs

Supernumerary robotic limbs (SLs) have the potential to extend human sensorimotor capabilities by increasing effective degrees of freedom. However, current systems are designed for a single task and cannot flexibly coordinate with natural limbs (NLs). Here we propose a hierarchic...

Optimizing the Ocular Surface Before, During, and After Glaucoma Surgery: A Narrative Review

This narrative review synthesizes the published literature on ocular surface disease (OSD) and glaucoma filtration surgery to develop practical, evidence-informed clinical and surgical recommendations for optimizing ocular surface management before, during, and after surgery. The...

Co-design of a wheelchair-mounted robotic arm for functional autonomy: a Cybathlon case study in user-driven assistive robotics

Abstract Background Wheelchair-mounted robotic arms may support functional autonomy for individuals with upper-limb disabilities, but their long-term usability remains limited by the difficulty of matching high-dimensional robotic control to heterogeneous motor capabilities, dail...

Impact of input modality on task-switching cost: A behavioural investigation of domain general versus modality-specific account of cognitive flexibility

Cognitive flexibility is one of the main executive functions, traditionally considered as part of domain-general, modality-independent, processes. Nevertheless, evidence from behavioural and brain-imaging studies suggests that this central ability remains sensitive to the modalit...
