Optimizing Portal Venous Phase Acquisition Quality of Contrast-Enhanced CT in Oncology

Background: Portal venous phase (PVP) contrast-enhanced CT is a cornerstone for response assessment in early-phase oncology trials, yet contrast-enhancement phase timing remains insufficiently monitored across sites. We assessed PVP timing using a validated artificial intelligenc...

A comparative study on the immobilization of organic-inorganic polyoxometalates hybrids onto gold electrodes: Direct versus indirect, covalent versus electrostatic grafting

Abstract We explored the conditions of the covalent grafting of organic-inorganic polyoxometalate hybrids onto gold using two basic reactions: the peptide-type coupling between a functionalized POM and a preformed organic self-assembled monolayer and the direct attachment of a th...

Redox Buffering and Corrosion in Molten Chloride Salts Dictated by Chlorobasicity

Abstract This study establishes an in situ synchrotron approach to directly link molten-salt chemistry, redox-buffer speciation, and alloy corrosion in chloride melts. Using a first-of-its-kind corrosion cell coupled to simultaneous X-ray absorption spectroscopy (XAS) and X-ray f...

Slow Frontal Spindle Activity and Declarative Memory Retention During Daytime Naps

ABSTRACT Memory consolidation refers to how newly encoded memories are strengthened and retained over time, and ample evidence indicates that sleep supports this process for both procedural and declarative memories. Although sleep spindles during non‐rapid eye movement (NREM) sle...

Nonlinear interpolation and the flow map of quasilinear equations

We prove an interpolation theorem for nonlinear functionals defined on scales of Banach spaces that generalize Besov spaces. It applies to functionals defined only locally, requiring only some weak Lipschitz conditions, extending those introduced by Lions and Peetre. Our analysis...

Agonistic interactions and vocalizations among Procellariiformes in multi-species feeding aggregations, observed through bird-borne cameras

Abstract Marine predators frequently aggregate at food sources, where interactions can range from cooperative group hunting to interference competition for resources. To investigate interactions at feeding aggregations among procellariiforms, we equipped wandering albatrosses Dio...

Multi-predator feeding aggregations in pelagic waters

Abstract Multi-predator feeding aggregations (MPFAs) are temporary co-occurrences of several species of predators simultaneously exploiting the same prey resource. Pelagic waters are home to the largest and most diverse MPFAs on the planet, however, our knowledge of the mechanism...

Cosmological Constraints from Full-scale Clustering and Galaxy–Galaxy Lensing with DESI DR1

Abstract We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy–galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. Our analysis includes four samples drawn from the Bright Galaxy Survey (B...

Paraneoplastic podocytopathies with nephrotic syndrome in solid cancers with C-Maf Inducing Protein expression

Abstract Background The main features of minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) associated with solid cancer (paraneoplastic podocytopathy with nephrotic syndrome, PPNS) remain poorly described. Methods In this French retrospective study, we fo...

Resolving the LiFePO4 Battery State beyond Voltage-Based Diagnostics Using Surface-Scan MRI

Reliable assessment of state of charge (SoC) and state of health (SoH) in commercial batteries remains a major challenge because their closed architecture obscures the underlying electrochemical, structural, and thermal processes, while existing diagnostic methods often provide o...

Efficacy and safety of temporary selective portal vein embolization before major hepatectomy (EMBORES): a phase 2 trial

Background Portal vein embolization (PVE) is routinely used before major hepatectomy to induce hypertrophy of the future liver remnant (FLR) and reduce post-hepatectomy liver failure. Conventional PVE relies on permanent embolic agents, resulting in irreversible portal occlusion,...

Thermoelasticity of mixed-mode cracks in layered transversely isotropic half-spaces

A three-dimensional spectral formulation is developed for steady thermoelastic penny-shaped cracks embedded in layered transversely isotropic half-spaces, with arbitrary stacking sequences and mechanically compliant and thermally resistive interfaces. Its central feature is a com...

The OpenSat4Weather dataset: Ku-band satellite link data for precipitation monitoring

Abstract. The TV-SAT signals received by the ground antennas of Satellite Microwave Links (SMLs) can be opportunistically used for identifying and quantifying precipitation. Hence, SMLs can serve as low-cost rainfall sensors complementary to conventional instruments. However, a s...

Making the diversity of CCI-related LEADER interventions comparable: A portfolio-to-case approach combining LLM-assisted coding and close reading

The EU LEADER program supports diverse rural local initiatives, which suits Cultural and Creative Industries (CCIs) related activities with their varied forms and place-specific resources. Yet its flexibility also complicates systematic comparison and learning, as portfolio patte...

Structure-activity relationship and membrane-targeting mechanisms of shikimate-related metabolites against Gram-positive and Gram-negative bacteria

AIMS: The rise of antibiotic-resistant bacteria has intensified the search for novel antimicrobials. In this context, shikimic acid is a versatile scaffold widely used as a precursor to bioactive compounds and drugs. This study screened the antimicrobial activity and underlying m...

Limited global awareness of invasive alien species and little support for their management

Invasive alien species (IAS) are one of the main drivers of global change and can cause a wide range of negative ecological and social impacts. Addressing these impacts requires management actions, which can fail to be effective when not supported by the public. Here, we conducte...

Minimizer Density Revisited: Models and Multiminimizers

High-throughput sequence analysis commonly relies on k-mers and sampling schemes to improve scalability and data locality. Among these, local schemes are widely used and are typically evaluated by their density, the expected fraction of selected positions. Minimizers are the most...

Revisiting quantum effects on dislocation glide in bcc metals from DFT calculations and machine-learning potentials

Quantum zero-point effects have been long proposed to explain a well-known discrepancy between the low-temperature flow stresses of body-centered cubic metals and corresponding atomistic models of plastic flow. Previous investigations on quantum effects relied on empirical intera...

Super Bloom: Fast and Precise Filter for Streaming k -Mer Queries

Approximate membership query structures are used throughout sequence bioinformatics, from read screening and metagenomic classification to assembly, indexing, and error correction. Among them, Bloom filters remain the default choice. They are not the most efficient structures in...

The robotic PIANO: a critical narrative review of surgeon-controlled operative polyphony, human factors, and robotic training

Abstract Robotic surgery can concentrate control of several technical functions at the console, but such concentration does not itself confer clinical independence, reduce dependence on the perioperative team, or improve patient outcomes. We define surgeon-controlled operative po...
