Spatiotemporal terahertz emission nanoscopy of spintronic photocurrent

Capturing ultrafast spin and charge photocurrents on nanoscopic scales is essential for fundamental research in physics and engineering, as well as for future applications, such as novel spin-orbitronic devices. Accessing the fundamental dynamics driven by changes in electronic e...

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...

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...

AI as the New Paint: A Systematic Review of AI as a Design Material

Artificial intelligence (AI) is increasingly influencing creative practice and workflows, with growing research exploring how it can be applied to advance creative work. In parallel, scholars have begun conceptualizing AI as a design material that practitioners can actively shape...

A review on catalyst deactivation in the oxidative desulfurization process: Causes and mitigation strategies

In recent years, oxidative desulfurization (ODS) has gained significant attention as a promising solution for removing sulfur compounds from fuel oils, particularly heavy marine fuels, to comply with increasingly stringent environmental regulations. While most ODS studies focus o...

Molecular mechanisms of supercritical CO2-induced interfacial softening in curcumin polymorphs

Unique properties of supercritical CO 2 (scCO 2 ) make it one of the most interesting “green” solvents for pharmaceutical particle formation and polymorph engineering. However, due to the complexity of the scCO 2 dynamics, the molecular mechanisms by which scCO 2 alters the stabi...

Enhancement of mechanical performance in metakaolin-based geopolymer by cyclic loading and creep process in relation with microstructural evolution

Geopolymers are more and more widely used in engineering applications as low carbon construction materials. Their mechanical properties under monotonic loading have been widely investigated. However, there is still a crucial need to investigate their mechanical responses under cy...

Interpretable machine learning for automatic rock mass classification in TBM tunneling: a case study of Beishan URL

Abstract Accurate rock mass classification is essential for safe tunnel boring machine (TBM) excavation, yet raw TBM monitoring data are often affected by shutdowns, machine adjustments, and transient disturbances, weakening their correlation with geological conditions. This stud...

Symmetry-based pulsed DNP and EPR sequences

Pulsed microwave irradiation provides more versatile control over spin dynamics than continuous-wave (CW) methods. This study adapts symmetry-based dipolar recoupling sequences, which are originally designed for magic angle spinning (MAS) NMR, to exploit electron-nuclear interact...

Valorization of Beach-Cast Biomass from the Invasive Seaweed Rugulopteryx okamurae on the Moroccan Coast: A Comparative Assessment of Extraction Conditions for Sodium Alginate Recovery

Rugulopteryx okamurae is an aggressively invasive seaweed whose proliferation along the Moroccan coastline represents both an ecological problem and an underexploited source of biomass. This work highlights the isolation of sodium alginate from R. okamurae under four combinations...

Coordinative chain transfer homopolymerization and copolymerization of bio‐sourced β ‐myrcene and butadiene promoted by iminopyridine iron complexes

Abstract A family of iron complexes bearing iminopyridine (ImPy) ligands with systematic variations on the N ‐aryl and pyridine moieties was evaluated as pre‐catalysts for the coordinative polymerization of β‐myrcene and butadiene. Upon activation with Al i Bu 3 and trityl borate...

Identification of Activity, Insulin, and Dietary Thresholds Associated With Exercise‐Related Hypoglycaemia and Hyperglycaemia in Children With Type 1 Diabetes: A Free‐Living Study Using Explainable Machine Learning

ABSTRACT Aims Some studies have explored associations between physical activity (PA) and hypoglycaemia in real‐life in type 1 diabetes (T1D) but without fully accounting for two major confounders, diet and insulin. We aimed to identify thresholds of PA characteristics, insulin, a...
