Edge of Chaos Theory Unveils the First and Simplest Ever Reported Hodgkin–Huxley Neuristor

Advanced Electronic Materials, EarlyView.
This manuscript presents the first and simplest ever‐reported electrical cell, which leverages one memristor on Edge of Chaos to reproduce the three‐bifurcation cascade, marking the entire life cycle from birth to extinction via All‐to‐None effect of an electrical spike, also referred to as Action Potential, across axon membranes under monotonic ...

Real‐time simulation multi‐point decoupling method of power systems based on terminal resistor

IET Generation, Transmission &Distribution, Volume 16, Issue 24, Page 4914-4923, December 2022., 2022
Abstract Traditional decoupling methods in real‐time simulation of complex power systems are poor in stability and unsatisfactory in use. In order to solve this problem, an improved decoupling method based on a terminal resistor is proposed. By paralleling a fixed‐value resistor and inverse‐paralleling a controlled current source in the traditional ...

Solution of boundary value problems for batteries: Operator‐theoretic methods

AIChE Journal, EarlyView.
Abstract Batteries with porous electrodes of negligible ionic and electronic conduction resistance are modeled with reaction‐diffusion equations in multilayered media. The classical separation of variables becomes inapplicable to battery problems because of nonlinearities in reaction rates and constraints of imposed current. A linear operator‐theoretic

Laplace transformations of hydrodynamic type systems in Riemann invariants: periodic sequences [PDF]

, 1997
The conserved densities of hydrodynamic type system in Riemann invariants satisfy a system of linear second order partial differential equations. For linear systems of this type Darboux introduced Laplace transformations, generalising the classical transformations in the scalar case. It is demonstrated that Laplace transformations can be pulled back to

Bioinspired Moisture‐Driven Soft Robotic Actuator

Advanced Intelligent Systems, EarlyView.
In response to the evolving field of robotics, the demand for soft actuator materials has surged, prompting a shift toward biomimetic models, notably plant‐based actuators. The Arundo donax species exemplifies a unique hinged single‐unit actuation system and a combined mechanism utilizing atmospheric water content, offering multifunctional capabilities.

Segmented transmission delay based decoupling for parallel simulation of a distribution network

IET Renewable Power Generation, Volume 17, Issue 1, Page 124-136, 6 January 2023., 2023
Abstract The introduction of inverters and power electronic devices increases the amount of calculation needed for electromagnetic transient simulation in distribution networks with a high proportion of distributed generation. Hence, the parallel calculation of electromagnetic transient simulation has become an effective way to improve its efficiency ...

Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations

Annalen der Physik, EarlyView.
A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

Lumped and distributed‐parameter pipe model framework for thermal transients: State‐space and transfer function theory and application to multi‐energy systems

IET Renewable Power Generation, Volume 17, Issue 1, Page 199-215, 6 January 2023., 2023
Abstract The accurate prediction and simulation of thermal transients in district heating networks is essential for the meaningful analysis of combined heat and power systems. For this purpose, the focus of this paper lies on the development of a consistent and comprehensive modelling framework that links diverse pipe model categories to specific ...

Laplace Transformations of Submanifolds [PDF]

arXiv, 2013
Let $x : M \to E^m$ be an isometric immersion of a Riemannian manifold $M$ into a Euclidean $m$-space. Denote by $\Delta$ the Laplace operator of $M$. Then $\Delta$ gives rise to a differentiable map $L :M \to E^m$, called the Laplace map, defined by $L(p)=(\Delta x)(p)$, $p\in M$. We call $L(M)$ the Laplace image, and the transformation $L :M \to L(M)$
