Asymptotic Analysis of Models of Superconductivity

open access: yes, 2002
After introducing the basic phenomena, the simplest (free-boundary) model describing the change of phase of a superconducting material is formulated. In some situations the model is ill-posed, and it is shown that it can be regularised in a certain parameter regime (type-I superconductors) by the Ginzburg-Landau model. For other parameter regimes (type-

Human‐in‐the‐Loop Swarms: A Bionic Swarm Approach to Real‐World Soil Mapping

open access: yesAdvanced Intelligent Systems, EarlyView.
This article introduces the “Bionic Swarm,” a novel system that lowers the barriers to real‐world swarm validation by abstracting difficult hardware tasks to app‐guided human agents. We demonstrate the system's utility through the experimental validation of a geotechnical soil‐mapping swarm algorithm and show superior performance to baseline approaches

Riesz basis and exponential stability for Euler-bernoulli beams with variable coefficients and indefinite damping under a force control in position and velocity

open access: yesElectronic Journal of Differential Equations, 2015
This article concerns the Riesz basis property and the stability of a damped Euler-Bernoulli beam with nonuniform thickness or density, that is clamped at one end and is free at the other.

A Memristor‐Based In‐Memory Computing System‐on‐Chip with Efficient Depthwise Convolution

open access: yesAdvanced Intelligent Systems, EarlyView.
We present a memristor‐based in‐memory computing (IMC) architecture that enables efficient depthwise convolution (DWC) acceleration. Fabricated in a system‐on‐chip with crossbar arrays, the design improves memory utilization. Experimental validation demonstrates the first hardware acceleration of DWC in IMC, achieving a digital comparable inference ...

Principles of Constructing Layered Neural Networks Based on Pulse Neurons

open access: yesМоделирование и анализ информационных систем, 2011
In the article we describe principles of pulse implementation of multilayer neural networks using biologically plausible neurons. It is shown that the multilayer perceptron can be modeled with a neural network composed of pulse neurons using impulse ...

Design Optimization of Soft Fabric Pneumatic Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a systematic optimization framework for elongating and bending fabric‐based soft pneumatic actuators. After a preliminary design‐space reduction, the framework minimizes energy consumption under mechanical performance constraints by integrating validated finite element modeling with statistical surrogate models. Optimal designs were

Epitaxial Oxide Interfaces Create Poison‐Resistant CuO Sites for Environmental Catalysis

open access: yesAngewandte Chemie, EarlyView.
An epitaxially stabilized CuO overlayer on Ti1−xInxO2 creates electron‐poor, high‐symmetry Cu–O sites that activate interfacial lattice‐oxygen redox. This interface promotes NOx reduction through an Eley–Rideal pathway, diverts sulfate formation, and sustains CH3SH deep oxidation via a Mars–van Krevelen cycle, offering a route to poison‐resistant ...

How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.
