Abstract Multilateral environmental agreements (MEAs) can be dynamic in that they evolve with the introduction and adaptation of new legal commitments. This research contributes to explaining such treaty dynamism by exploring its diffusion across institutions. I focus on the role of the European Union (EU) and the Unit...
Abstract How do spatial proximity, policy networks, and temporal dynamics interact to shape education policy diffusion across the American states and have these channels of influence changed over time? This study introduces an integrated framework combining spatial-X (SLX) estimation, exogenously constructed policy-pat...
During the aqueous corrosion of zirconium alloy cladding, the diffusion behavior of hydrogen within the oxide layer is a critical factor governing the hydrogen uptake rate. As the migration mechanisms of hydrogen in monoclinic zirconia (m-ZrO2) and the influence of defects on its diffusion remain unclear, there is stil...
Abstract Unimolecular nanogels (NGs) based on (hyper)branched cyclic polyglycerols ((h)bcPGs) of two molecular weights (Mn = 8 and 60 kDa) were prepared through intramolecular cross-linking with the tetraboronic acid–functionalized porphyrin, 5,10,15,20-(tetra-4-dihydroxyborylphenyl) porphyrin (TPP-4B) under mildly bas...

Although short-video platforms disseminate content constantly, the resulting spread is far from uniform, since a limited set of videos rapidly attract disproportionate attention while the overwhelming majority receive only marginal engagement, a pattern that researchers commonly describe as a video 'going viral.' Becau...
Abstract Bouncing packets are quasi‐periodic microbursts separated by the electron bounce period. Solar Anomalous and Magnetospheric Particle Explorer observations revealed relativistic (>1 MeV) inner‐belt bouncing packets with “crown,” “decaying,” and “flat” envelopes. We test whether ducted lightning‐generated whistl...
The rapid diffusion of artificial intelligence (AI) is reshaping how firms create value. Although a growing literature examines the economic consequences of AI, relatively little attention has been paid to how human capital conditions the relationship between AI exposure and firm value. Based on the pro-worker AI frame...
Choroid plexus (ChP) morphology and periventricular diffusion alterations have been implicated in Alzheimer’s disease (AD). However, whether ChP volume and the diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) index provide complementary glymphatic-related MRI information, and whether thei...
Difficult-to-machine materials, including titanium alloys, nickel-based superalloys, hardened and high-strength steels, stainless steels, and fiber-reinforced composites, are widely used in advanced manufacturing but impose severe thermo-mechanical–chemical loads on cutting tools, resulting in progressive wear and degr...
High-altitude (HA) environments, conventionally defined as elevations above 2,500 m, provide a distinctive natural setting for investigating how the human brain responds to sustained environmental stress. Reduced barometric pressure and oxygen availability coexist with cold, aridity, ultraviolet radiation, and large di...
Abstract The article revisits Schneider and Schröder’s (2021) assessment of Namibian English (NamE) as a ‘non‑postcolonial’ variety that has moved from a phase of diffuse normative input into a yet uncompleted Phase 3 (‘nativization’) and that – due to ‘ethnic variation’ – remains well short of displaying the ‘homogene...
Generative Adversarial Networks (GANs) and diffusion models are two mainstream approaches in image generation. Although their underlying principles differ, both can be unified under the framework of particle models (PMs). GANs enable fast generation but suffer from unstable training and mode collapse, whereas diffusion...
