Crater Observing Bioinspired Rolling Articulator (COBRA)

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Discrete port-Hamiltonian system model of a single-reed woodwind instrument

open access: yesFrontiers in Signal Processing
Time-domain simulation of woodwind instruments typically involves the development of separate discrete-time sub-models for the excitation mechanism and the resonator.

On switched Hamiltonian systems [PDF]

open access: yes, 2002
In this paper we study the well-posedness and stability of a class of switched linear passive systems. Instrumental in our approach is the result, also of interest in its own right, that any linear passive input-state-output system with strictly positive

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

The wave equation as a port-Hamiltonian system and a finite-dimensional approximation [PDF]

open access: yes, 2002
The problem of approximating a distributed parameter system with free boundary conditions is solved for the 2-dimensional wave equation. To this end we first model the wave equation as a distributed-parameter port-Hamiltonian system.

Photonic Unitary Circuits for Quantum Information Processing

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Unitary transformations are the cornerstone of quantum computing, enabling reversible manipulation of quantum states. This review evaluates photonic waveguide architectures as an evolving solution for quantum computing, exploiting the unique properties of photons. It investigates current theoretical frameworks, material platforms, and design strategies.

Finite-time thermodynamics of port-Hamiltonian systems

open access: yes, 2013
In this paper, we identify a class of time-varying port-Hamiltonian systems that is suitable for studying problems at the intersection of statistical mechanics and control of physical systems.

Decoding pH‐Driven Phase Transition of Lipid Nanoparticles

open access: yesSmall, 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

Trade costs, infrastructure, and dynamics in a global economy

open access: yesInternational 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

Energy-Based Trajectory Tracking Control of a Six-DOF Robotic Manipulator Using the Port-Hamiltonian Framework

open access: yesMachines
Structure-preserving trajectory tracking control for a six-degree-of-freedom robotic manipulator is developed within the port-Hamiltonian framework. Error Hamiltonian is constructed by incorporating configuration and momentum tracking errors into the ...
