Predicting near-term, out-of-sample fish passage, guidance, and movement across diverse river environments by cognitively relating momentary behavioral decisions to multiscale memories of past hydrodynamic experiences

Frontiers in Ecology and Evolution, 2023
Predicting the behavior of individuals acting under their own motivation is a challenge shared across multiple scientific fields, from economic to ecological systems.

Three‐Dimensional Model for Consolidation‐Induced Solute Transport in a Nearly Saturated Porous Medium

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Understanding solute transport in heterogeneous porous media under variable loading is essential for effective pollution mitigation. However, most existing studies rely on one‐ or two‐dimensional simplifications, limiting their capacity to capture three‐dimensional stress–transport interactions.

Parameterized Edge Hamiltonicity

, 2014
We study the parameterized complexity of the classical Edge Hamiltonian Path problem and give several fixed-parameter tractability results. First, we settle an open question of Demaine et al.

Modelling Wetting Collapse, Failure and Deposition of an Unsaturated Slope With Material Point Method

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The paper presents the modelling of unsaturated soils with the material point method (MPM), including the effect of wetting leading to the loss of strength and the volumetric collapse. The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an ...

Numerical simulation of the natural fragmentation of explosively loaded thick walled cylinders

Defence Technology, 2014
The ability to predict the natural fragmentation of an explosively loaded metal casing would represent a significant achievement. Physically-based material models permit the use of small scale laboratory tests to characterise and validate their ...

Even-cycle decompositions of graphs with no odd-$K_4$-minor

, 2017
An even-cycle decomposition of a graph G is a partition of E(G) into cycles of even length. Evidently, every Eulerian bipartite graph has an even-cycle decomposition.

Large‐eddy simulation with Lagrangian cloud modeling and large‐scale dynamics (L3$$ {\mathrm{L}}^3 $$) for studying the marine fog life cycle

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study explores the life cycle of marine fog using a novel L3$$ {\mathrm{L}}^3 $$ coupling method, which integrates large‐eddy simulation (LES), Lagrangian cloud modeling (LCM), and large‐scale dynamics (LSD). Simulations of two fog episodes observed during the FATIMA campaign revealed key insights into the fog's microphysical and dynamic ...

Parameterized Rural Postman Problem [PDF]

, 2014
The Directed Rural Postman Problem (DRPP) can be formulated as follows: given a strongly connected directed multigraph $D=(V,A)$ with nonnegative integral weights on the arcs, a subset $R$ of $A$ and a nonnegative integer $\ell$, decide whether $D$ has a
