AI‐BioMech: Deep Learning Prediction of Mechanical Behavior in Aperiodic Biological Cellular Materials

open access: yesAdvanced Intelligent Discovery, EarlyView.
AI‐BioMech is a deep learning framework that predicts the mechanical behavior of biological cellular materials directly from 2D images. By replacing traditional finite element analysis with semantic segmentation, it identifies stress and strain distributions with 99% accuracy, offering a high‐speed, scalable alternative for analyzing complex, aperiodic

Detecting introgression from phylogenetic invariant site patterns using machine learning

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Detecting historical introgression among populations or species from genomic data is a common goal in evolutionary genetics. Most current methods fall into two major categories: network inference and admixture inference. Network inference (e.g., SNaQ) is computationally challenging and typically requires first reducing large genomic ...

Timber production and ecological characteristics of trees in coppice forest in the Voskop nature reserve in Český kras - a case study

open access: yesJournal of Forest Science, 2014
Anew approach to forestry that increasingly values non-timber forest functions brings new interest and value also to coppice forests. A case study in the Voskop nature reserve located in the Český kras Protected Landscape Area was focused on a comparison
