A Machine Learning Model for Interpretable PECVD Deposition Rate Prediction
Advanced Intelligent Discovery, EarlyView.This study develops six machine learning models (k‐nearest neighbors, support vector regression, decision tree, random forest, CatBoost, and backpropagation neural network) to predict SiNx deposition rates in plasma‐enhanced chemical vapor deposition using hybrid production and simulation data.

Distribution and size of elements of Saturn's rings as inferred from 12-cm radar observations [PDF]
A 64m radar antenna was used to observe Saturn's rings at 12.6 cm wavelength, with reduced Doppler spread. The results show a positive radar return corresponding to about a 60 percent return from an isotropic scatterer with the projected area of the ...

Impact of Biomimetic Pinna Shape Variation on Clutter Echoes: A Machine Learning Approach
Advanced Intelligent Systems, EarlyView.Bats with dynamic ear structures navigate dense, echo‐rich environments, yet the echoes they receive are highly random. This study shows that machine learning can reliably detect structural signatures in these seemingly chaotic biosonar signals. The results open new directions for biologically inspired sensing, where time‐varying receiver shapes ...

Animal Models and Experimental Medicine, EarlyView.This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.

Back Again to the Future: A New Era for Cerebroprotection
Annals of Neurology, EarlyView.Cerebroprotection is a fresh framework for designing neurological therapy that targets glia and vascular cells, in addition to neurons. In the future, successful cerebroprotection will involve targeting all elements of the neurovascular unit. Preclinical trials must include functional outcomes, as well as lesion morphometry.
