Time‐Domain Simulator for Nonuniform Transmission Lines: An Educational Tool

Computer Applications in Engineering Education, Volume 34, Issue 4, July 2026.
ABSTRACT The study of transmission lines is a key topic in electrical and electronic engineering education. However, their theoretical formulation can be complex, often hindering students' understanding of the underlying physical phenomena. In contrast, transmission lines exhibit intuitive and engaging behaviors. To address this challenge, we developed

A Coupled Chemohydraulic Model of a Hydration Experiment

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 10, Page 4284-4294, July 2026.
ABSTRACT This article presents a model for the hydration of periclase into brucite during water infiltration into a dry, pure periclase core. The hydration process proceeds in two stages. In Phase I, an infiltration front advances through the core while simultaneously triggering the hydration reaction.

Coexistence, crossover and extirpation in coalescent communities and ecotones

Oikos, Volume 2026, Issue 7, July 2026.
When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.

A Conjugate Operator Pair of Partial Differential Equations Bridging Born and Kirchhoff Approximations for Wave‐Equation Inversion

Geophysical Prospecting, Volume 74, Issue 6, July 2026.
ABSTRACT A conjugate operator pair is introduced for wave‐equation Kirchhoff modelling and migration, formulated as time‐space partial differential equations. The operator pair allows for iterative linearized waveform inversion and supports the reconstruction of angle‐dependent reflectivity images. The proposed forward modelling operator represents the

Discharge‐Targeted Hydraulic Tomography to Quantify and Locate Aquifer Discharge

Groundwater, Volume 64, Issue 4, Page 466-482, July/August 2026.
Abstract Quantifying and localizing groundwater discharge is inherently difficult. It requires knowledge about hydraulic conductivity and the hydraulic gradient on the scale of interest. Conventional hydraulic testing, such as pumping tests, may fail in the presence of heterogeneity and complex structural boundaries.

Afforestation priority for multiple objectives at national scale: Italy as a case study

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Afforestation is increasingly recognized as a key strategy to address climate change and ecological degradation, offering multiple ecosystem services. However, strategic planning is needed to ensure that afforestation actions are ecologically effective and economically efficient by targeting areas where ecosystem service provision

Time‐Resolved SNOM via Phase‐Domain Sampling

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Time‐resolved scanning near‐field optical microscopy (tr‐SNOM) grants access to the dynamic dielectric function of monolayer and multilayer WS2, using visible wavelengths. In order to use a femtosecond laser with a repetition rate of 200 kHz, the signal is sampled and demodulated in the modulation phase domain, marking the first realization of tr‐SNOM ...

Modelling of stress relaxation under one-step deformation of nonlinear viscoelastic materials using the Heaviside function

International Scientific and Technical conference "The Progressive Technics, Technology and Engineering Education"
The problem of calculating the stress relaxation of nonlinear viscoelastic materials under one-step deformation is considered. The loading program is implemented using the unit Heaviside function. To describe the deformation process, a nonlinear creep model with time-independent nonlinearity of the Rabotnov model type is used.
