HOST MATTER: Parasite infection drives chemical reconfiguration of decomposing host and shapes insect behavioural responses

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host–parasite interactions shape ecosystems by driving species dynamics, yet their influence is typically considered in terms of host mortality rather than the chemical environments generated during infection and decomposition.

Generalized eigenvalue approach for dynamic mode decomposition

AIP Advances, 2021
Traditional dynamic mode decomposition (DMD) methods inevitably involve matrix inversion, which often brings in numerical instability and spurious modes.

Closing Trajectories: Equation‐Free Cyclic Animation via Koopman Surrogates

Computer Graphics Forum, EarlyView.
Abstract Cyclic animation is widely used in computer graphics and interactive content. It supports seamless playback in games, VR, and interactive simulation, where short clips must repeat smoothly over long durations. Converting an observed non‐cyclic trajectory into a seamless loop is challenging because the endpoint states of the observed sequence ...

Tensor-based dynamic mode decomposition

, 2018
Dynamic mode decomposition (DMD) is a recently developed tool for the analysis of the behavior of complex dynamical systems. In this paper, we will propose an extension of DMD that exploits low-rank tensor decompositions of potentially high-dimensional ...

From isotopologues to isotopomers: advances in mass spectrometry‐based positional 13C analysis in plants

New Phytologist, EarlyView.
Workflow of gas chromatography coupled to mass spectrometry (GC‐MS)‐based 13C‐labelling analysis of plant metabolites. Summary Carbon fluxes throughout metabolic networks can be investigated experimentally through 13C‐isotope labelling experiments (13C‐ILE) and 13C‐metabolic flux analysis (13C‐MFA).

Partial Observation of Linear Systems With the Mori–Zwanzig Formalism

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The Mori–Zwanzig (MZ) formalism provides a systematic framework for deriving reduced‐order model of dynamical systems when only part of the state is observed, but its practical use is often limited by the complexity of the resulting computations.

Unsteady Analysis of Molten Salt Pump Based on Dynamic Mode Decomposition [PDF]

Journal of Applied Fluid Mechanics
As the main heat storage medium in photothermal power station, binary molten salt undergoes thermal decomposition above 450°C, generating gas that accumulates within molten salt pump flow passages and affects pump performance.

Dynamic mode decomposition of inertial particle caustics in Taylor–Green flow

Scientific Reports, 2021
Inertial particles advected by a background flow can show complex structures. We consider inertial particles in a 2D Taylor–Green (TG) flow and characterize particle dynamics as a function of the particle’s Stokes number using dynamic mode decomposition (

Exact Principal Koopman Eigenfunctions of a Pendulum

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The Koopman operator framework offers a rigorous approach to representing nonlinear dynamical systems through linear (or bilinear) differential equations. For deterministic, dissipative systems, it guarantees the existence of global coordinate transformations that linearize autonomous systems and bilinearize input‐affine systems. Despite these
