On the Method of Harmonic Balance for Lumped‐Element Transformer Models

International Journal of Circuit Theory and Applications, Volume 54, Issue 2, Page 625-637, February 2026.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Seismic Structural Response and Loss Estimation for Dense Urban Districts Using Neural Network Parameterized Gaussian Process

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 397-412, February 2026.
ABSTRACT Earthquakes pose a major threat to urban areas, causing fatalities, injuries, and significant economic losses. This study proposes a Gaussian process parametrized by deep neural networks (DNN–GP) as an efficient surrogate for assessing seismic losses of building structures at a regional scale.

A Method for the Combination of Stochastic Time Varying Load Effects [PDF]

, 1983
The problem of evaluating the probability that a structure becomes unsafe under a combination of loads, over a given time period, is addressed. The loads and load effects are modeled as either pulse (static problem) processes with random occurrence ...

Semi‐Active Movable Shear Keys for Seismic Response Control of Bridges

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 483-499, February 2026.
ABSTRACT The size of the joint gaps plays a significant role in the dynamic performance of bridges. This has recently motivated the consideration of movable shear keys (MSKs), pioneered by the corresponding author, to enhance bridge performance by changing the bridge support/boundary conditions.

Frequency‐Domain Analysis of a Keldysh‐Like System

International Journal of Robust and Nonlinear Control, Volume 36, Issue 2, Page 671-682, 25 January 2026.
ABSTRACT Complex dynamics of the system, revealing flutter and first presented by M. Keldysh, is analyzed in the paper in the frequency domain, through the describing function method. Motivated by this analysis, a system with similar behavior, but suitable for the exact frequency‐domain analysis through the locus of a perturbed relay system (LPRS ...

AC Current‐Driven Magnetization Switching and Nonlinear Hall Rectification in a Magnetic Topological Insulator

Advanced Materials, Volume 38, Issue 4, 16 January 2026.
This study reports alternating‐current (AC) driven magnetization reversal in a semi‐magnetic topological insulator (Cr,Bi,Sb)2Te3/(Bi,Sb)2Te3, with low current density. Time‐domain Hall voltage measurements reveal a nonlinear and rectified Hall effect, along with higher‐harmonic responses and hysteresis.

Geometric Limits for the Seismic Design of Unreinforced Masonry Fence Walls

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 1, Page 130-149, January 2026.
ABSTRACT Current seismic design standards require masonry free‐standing walls to comply with regulations for masonry structural walls. Applying these current seismic design standards to fence walls (free‐standing walls) may be inappropriate due to the different restraint conditions between fence walls and structural walls.
