Color Symmetry Breaking in a Nonlinear Optical Microresonator
Laser &Photonics Reviews, EarlyView.A two‐color pump drives an integrated microring resonator into spontaneous color symmetry breaking mediated by the nonlinear Kerr effect. Above threshold, one optical color becomes spontaneously dominant while the other is submissive, with the selected output state emerging randomly. These results establish a new form of symmetry breaking in integrated

Elevator dynamic monitoring and early warning system based on machine learning algorithm
IET Networks, EarlyView., 2022 In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

Bounded Frequency Lattices in Coupled Lithium Niobate Ring Cavities
Laser &Photonics Reviews, EarlyView.We leverage coupled asymmetric ring resonators in realizing bounded tight‐binding frequency lattices and demonstrate their discrete band structures on an integrated device. Suppression of long‐range coupling with a single auxiliary cavity is demonstrated by combining mode splitting and coupled waveguide dispersion effects.

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach
Naval Research Logistics (NRL), EarlyView.ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting

Simultaneous Network Design With Restricted Link Usage
Networks, EarlyView.ABSTRACT Given a digraph with two terminal vertices s$$ s $$ and t$$ t $$ as well as a conservative cost function and several not necessarily disjoint color classes on its arc set, our goal is to find a minimum‐cost subset of the arcs such that its intersection with each color class contains an s$$ s $$‐t$$ t $$ dipath.

Thinking with trees: Responding to sympoietic plant relations through visual art
PLANTS, PEOPLE, PLANET, EarlyView.Amid escalating climate crises, this paper explores how we might rethink our relationship with the natural world, particularly with plants and trees, through the perspectives of visual art. This paper reveals how art invites us to see trees and other plant life not as passive background scenery, but as living beings with their own forms of experience ...
