Damage identification and model updating using bridge displacement under moving vehicles with uncertain weight

Bridge damage incurred during long-term service leads to discrepancies between the physical structure and its digital twin finite element (FE) model, necessitating regular model updates to ensure reliable health monitoring. Traditional methods typically adopt a two-step framework...

Hydrodynamics substantially affects induced structure formation in magnetic fluids

Magnetorheological fluids consist of micrometer-sized magnetic particles in a carrier liquid. Sufficiently strong external magnetic fields lead to the formation of string-like particle aggregates. We demonstrate that hydrodynamic interactions, that is, mutual couplings via induce...

Rapid genome-wide purging following tsunami-induced hybridization in a stickleback population

Speciation is the process by which barriers to gene flow evolve between populations. As speciation approaches completion, genome-wide divergence can be maintained in the face of hybridization. Because real-time observations of genomic changes following hybridization in natural po...

Unraveling the Hydration Behavior of Poly(2-Methoxyethyl Acrylate) and Its Model Monomer via Molecular Dynamics Simulations

Abstract The hydration behavior of polymeric materials is governed by a subtle interplay between local chemical functionality and polymer backbone connectivity. In this work, we investigate the hydration behavior of poly(2-methoxyethyl acrylate) (PMEA) and its monomeric analogue,...

A honey trap for Platycerus (Coleoptera: Lucanidae): Georeferenced captures indicate forest-habitat patterns in operational broadleaf forestry

Biodiversity-oriented broadleaf forestry needs practical indicators that translate local forest-habitat conditions into information useful for silvicultural and operational decisions. Here, we used the Female-attracted Flight Interception Trap (F-FIT) to quantify spatial variatio...

A hydro-mechanical mechanism for cyclic ratcheting of embedded cantilever retaining walls in saturated sand

Saturated backfills behind embedded cantilever walls deform through coupled hydro-mechanical processes that pseudo-static methods cannot capture. Three 40 g dynamic centrifuge tests are presented to isolate how the pre-seismic static state, set by wall flexural stiffness, togethe...
