Ch‐Ch‐Ch‐Ch‐Changes: The Impact of Supply Base Growth, Contraction, and Turnover on Firm Innovation

open access: yesJournal of Operations Management, EarlyView.
ABSTRACT Modern supply chains are experiencing more disturbances due to regulatory shifts, rising sustainability standards, emerging or declining markets, and disruption to critical inputs. Some firms react by strengthening existing supplier partnerships to resist changes, while others reconfigure relationships with suppliers to embrace changes ...

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Mobile Payment Adoption in China: A Comment on Vatsa et al.

open access: yesManagerial and Decision Economics, EarlyView.
ABSTRACT Vatsa et al. examine the determinants of mobile payment adoption in China. They do so by applying a probit model to data from a nationally representative survey. In this comment, we identify several conceptual and econometric limitations that affect the robustness of Vatsa et al.'s findings.

Risk Times in Mission‐Oriented Systems

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT This article assesses risk times in mission‐oriented systems with high safety standards. We examine critical times under two safety policies. The first requires that the system's reliability function, known the first failure of the components, must exceed a reliability level throughout the mission.

High‐Precision Measurement of Time Delay with Frequency‐Resolved Hong‐Ou‐Mandel Interference of Weak Coherent States

open access: yesAdvanced Quantum Technologies, EarlyView.
High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Autonomous Navigation in Large‐Scale Underground Environments Based on a Purely Topological Understanding of Tunnel Networks

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...
