A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

open access: yesEnergy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Wide‐range and high‐resolution Young's modulus sensing enabled by a complementary indentation‐protrusion architecture

open access: yesFlexMat, EarlyView.
A tactile sensor integrating indentation and protrusion sensing within a single platform enables accurate perception of object Young's modulus. This complementary architecture expands the detectable Young's modulus range to 25.8–2639.2 kPa and achieves an object recognition accuracy of 94.27%, outperforming indentation‐only (84.59%) and protrusion‐only

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

Multifidelity Thermochemical–Mechanical Modeling of Pultruded Hollow Composite Profiles

open access: yesJournal of Manufacturing Science and Engineering, EarlyView.
ABSTRACT Pultrusion of hollow composite profiles with fast‐curing polyurethane (PU) resin requires simultaneous control of heat transfer, cure kinetics, viscosity evolution, and pulling resistance, making empirical process optimization costly and uncertain.

Investigation of Tire‑Tread Rubber Hysteretic Behaviour on Aggregates Through Experiments and Modelling

open access: yesJournal of Tribology, EarlyView.
ABSTRACT Friction between tire rubber and pavement is governed by the interplay of hysteresis and adhesion yet their individual contributions remain difficult to quantify. This study addresses the long‐standing challenge by using reciprocating sliding tests by means of a tribometer and viscoelastic finite element modelling (FEM) to investigate rubber ...
