Discrete-time port-Hamiltonian systems: A definition based on symplectic integration [PDF]
, 2018 We introduce a new definition of discrete-time port-Hamiltonian systems (PHS), which results from structure-preserving discretization of explicit PHS in time.

Decoding pH‐Driven Phase Transition of Lipid Nanoparticles
Small, Volume 22, Issue 14, 6 March 2026.Ionizable aminolipids govern lipid nanoparticle (LNP) function through environment‐dependent protonation. Constant‐pH molecular dynamics reveal intrinsic, apparent, and surface pKa${\rm pK}_{\text{a}}$ values within LNP‐mimetic membranes, demonstrating that the LNP lipid environment induces a pronounced downward pKa${\rm pK}_{\text{a}}$ shift exceeding

An Energy-Balancing Perspective of Interconnection and Damping Assignment Control of Nonlinear Systems [PDF]
, 2003 Stabilization of nonlinear feedback passive systems is achieved assigning a storage function with a minimum at the desired equilibrium. For physical systems a natural candidate storage function is the difference between the stored and the supplied ...

Trade costs, infrastructure, and dynamics in a global economy
International Journal of Economic Theory, Volume 22, Issue 1, Page 40-62, March 2026.Abstract This study develops a dynamic two‐country model with trade costs linked to international infrastructure stock. With variable markups and firm heterogeneity, the welfare impact of trade costs depends on firms' cost distribution. Governments engage in a dynamic public investment game, leading to multiple steady states. The dynamic equilibrium of

Port-Hamiltonian systems and monotonicity
, 2022 The relationships between port-Hamiltonian systems modeling and the notion of monotonicity are explored. The earlier introduced notion of incrementally port-Hamiltonian systems is extended to maximal cyclically monotone relations, together with their generating functions.

Nonreciprocal Terahertz Propagation via InSb Topological Photonic Crystals
Advanced Photonics Research, Volume 7, Issue 2, February 2026.Addressing the challenge of high magnetic field requirements in conventional gyromagnetic materials, this article investigates indium antimonide (InSb) rod arrays operating at terahertz frequencies. By exploiting the synergy between the Voigt effect and the dispersive scaling properties, robust unidirectional propagation is achieved under a remarkably ...

Weak-Hamiltonian dynamical systems
, 2007 A big-isotropic structure $E$ is an isotropic subbundle of $TM\oplus T^*M$, endowed with the metric defined by pairing. The structure $E$ is said to be integrable if the Courant bracket $[\mathcal{X},\mathcal{Y}]\in\Gamma E$, $\forall\mathcal{X},\mathcal{

Engineering Reports, Volume 8, Issue 2, February 2026.Quantum computing techniques such as Quantum Annealing and Quadratic Unconstrained Binary Optimization are effectively solving NP‐hard problems in operations management and research, particularly in logistics, manufacturing, and finance. This study maps these applications to present a framework for future adoption across industries. ABSTRACT This study
