Port-Hamiltonian systems and monotonicity
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.

Topological Photonic Devices and Circuits at Terahertz Frequencies
This review examines how 3D topological insulators and emerging topological photonic phases enable robust, low‐loss and defect‐immune terahertz devices. Fundamental properties, device implementations and topological transport mechanisms are surveyed, revealing new opportunities for reconfigurable, high‐performance THz components and scalable ...

Multiplexing Two Types of High‐Order Topological Corner States in Kagome Lattice Photonic Crystals
Higher‐order topological corner states in kagome photonic crystals exhibit a direction‐wavelength locking mechanism: two corner states with distinct resonant frequencies couple to different output channels. Harnessing this effect, a 1 × 2 wavelength demultiplexer achieves low‐crosstalk signal separation, demonstrating the potential of topological ...

Time-Varying Impedance Control of Port Hamiltonian System with a New Energy-Storing Tank
In order to guarantee the passivity of a kind of conservative system, the port Hamiltonian framework combined with a new energy tank is proposed in this paper. A time-varying impedance controller is designed based on this new framework.

Modeling and Control of a Rotating Flexible Spacecraft: A Port-Hamiltonian Approach [PDF]
In this brief, we develop a mathematical model of a flexible spacecraft system composed of a hub and two symmetrical beams using the port-Hamiltonian framework. This class of system has favorable properties, such as passivity for controller synthesis and

End‐to‐End Portfolio Optimization with Hybrid Quantum Annealing
This works presents a hybrid quantum‐classical framework for portfolio optimization that combines quantum assisted asset selection and rebalancing with classical weight allocation. The approach processes real market data, embeds it into Quadratic Unconstrained Binary Optimization formulations, and evaluates performance within a unified workflow ...

Scattering for infinite dimensional port Hamiltonian systems [PDF]
In this paper, an introduction to scattering for infinite dimensional systems within the framework of port Hamiltonian system is presented. The classical results on wave propagation can be extended to generic power propagation phenomena, for example to fluid dynamics or flexible structures.

Testing Hypotheses of Covariate Effects on Topics of Discourse
ABSTRACT We introduce an approach to topic modeling with document‐level covariates that remains tractable in the face of large text corpora. This is achieved by de‐emphasizing the role of parameter estimation in an underlying probabilistic model, assuming instead that the data come from a fixed but unknown distribution whose statistical functionals are
