Exact Solutions and Nonlinear Dynamical Behavior in a Navier‐Stokes‐Type Model for Elastic Cylindrical Vessels: An Analytical and Computational Approach

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
This study investigates a nonlinear Navier‐Stokes‐type model for elastic cylindrical vessels. Exact solutions are derived via the Bäcklund transformation and the ϕ6$$ {\phi}^6 $$‐expansion method, and dynamical behaviors are analyzed using bifurcation and chaos tools, revealing diverse wave structures and parameter‐dependent propagation characteristics.

Efficient Numerical Framework for Geothermal Energy Production Optimization in Fracture‐Controlled Reservoirs

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 6, Page 709-730, June 2026.
We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled

Quadratic Hedging of American Options Under GARCH Models

open access: yesJournal of Futures Markets, Volume 46, Issue 6, Page 1079-1097, June 2026.
ABSTRACT American options are widely traded in financial markets, yet there is a scarcity of literature on hedging in incomplete markets. In this paper, we derive optimal hedging ratios and option values using Local Risk Minimization (LRM) and Global Risk Minimization (GRM) hedging strategies through dynamic programming.

Lifespan Trajectories of Asymmetry in White Matter Tracts

open access: yesHuman Brain Mapping, Volume 47, Issue 8, June 1, 2026.
(A) Large‐scale lifespan modeling of white matter asymmetry. Diffusion MRI data from 35,000+ individuals (0‐100 years) across 50 cohorts were used to generate normative lifespan trajectories of white matter asymmetry. Thirty bilateral tracts were segmented, and microstructural (FA, MD, AD, RD) and macrostructural (volume, length) features were ...

Deep Learning Unlocks Behavioral Prediction and Neurobehavioral Decoding

open access: yesMed Research, Volume 2, Issue 2, Page 371-387, June 2026.
This review evaluates deep learning frameworks that surmount conventional limitations through high‐dimensional nonlinear modeling, spatiotemporal dependency capture, and multimodal information integration. Focusing on biological behavior forecasting and neural mechanism decoding, we delineate cutting‐edge applications, including real‐time action ...
