The impact of inhibitory control and working memory capacity on verbal-humor processing: an ERP investigation

Abstract Verbal-humor processing is a sophisticated cognitive-emotional task. While domain-general executive functions like inhibitory control (IC) and working memory capacity (WMC) are known to influence language comprehension, their specific, stage-dependent contributions to th...

Structural Modification of Bifenox Derivatives: Discovery of Novel Diaryl Thioethers as Potent Insect Trehalase Inhibitors

Abstract To discover novel noncarbohydrate trehalase inhibitors, 62 bifenox derivatives were designed and synthesized in this study. Among them, diaryl thioether 2b-1 exhibited optimal trehalase inhibitory activity with 72.5% inhibition rate at 100 μM and a Ki value of 36.3 μM, s...

Pressure‐Induced Single‐Molecule Deformation Enables 208‐Fold Photoluminescence‐Intensity Enhancement in Zero‐Dimensional Copper Iodide Hybrids

ABSTRACT Hybrid metal halides exhibit diverse excited‐state behaviors, yet the molecular‐level origin of pressure‐induced emission enhancement (PIEE) remains elusive. Here, we develop a rational molecular design strategy to isolate pressure‐induced single‐molecule deformation as...

Biotin‐Engineered Phenothiazine Photosensitizer Boosts Type I Photodynamic Therapy via Singlet‐Excited‐State Electron Transfer

Comprehensive Summary Type II‐dominant photosensitizers often suffer from reduced photodynamic efficacy under tumor hypoxia. We report a biotin‐modified phenothiazine photosensitizer termed DHU‐Blue‐7, which converts type II methylene blue (MB)‐like photosensitization into a type...

Adaptive optimization and interaction method for immersive exhibition space experiences integrating multimodal physiological sensing

Interactions in immersive exhibition halls rely heavily on explicit inputs such as controllers and touchscreens, making it difficult to respond in real time to users’ unconscious emotional fluctuations, which frequently disrupts immersion. This paper proposes an adaptive optimiza...

Experimental identification and robust optimization of spindle–bearing systems with reliability constraints

Effective vibration control and dynamic behavior management in the presence of parameter uncertainties are critical for high-speed motorized spindles. Although traditional robust design optimization minimizes dynamic response variability, it lacks explicit control over failure pr...

Boron‐embedded multifunctional nanoplatform toward potential combined boron neutron capture therapy and immunomodulation in glioma

Abstract Glioma poses a formidable therapeutic challenge due to its cellular heterogeneity, invasiveness and the protective blood‐brain barrier (BBB). Boron neutron capture therapy represents a promising binary targeted radiotherapy, but its efficacy is hampered by insufficient t...

A Microfluidic System for Particle Enrichment by Integrating an Acoustic Field With Oscillatory Flow

Triazine Crosslinking Enables Nitrogen‐Enriched Carbon Molecular Sieve Membranes for Precision 1,3‐Butadiene/n‐Butane Separation

ABSTRACT Membrane separation provides an energy‐efficient route for separating 1,3‐butadiene (C 4 H 6 ) from C 4 hydrocarbon mixtures, but limited permeability and selectivity remain key barriers. Here, nitrogen‐enriched carbon molecular sieve (CMS) membranes were fabricated from...

Optimal control of spiral waves in heterogeneous excitable media: non-monotonic efficacy of localized optogenetic inhibition

Structural heterogeneity stabilizes spiral waves in excitable media, yet how its spatial architecture, ranging from diffuse interstitial deposition to focal scar patterns, modulates the efficacy of localized optogenetic control remains poorly understood. Using a two-dimensional c...
