Non-Gaussian curvature distribution of actin-propelled biomimetic colloid trajectories
, 2008 We analyze the motion of colloids propelled by a comet-like tail of polymerizing actin filaments. The curvature of the particle trajectories deviates strongly from a Gaussian distribution, implying that the underlying microscopic processes are ...

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Orientation tuning of curvature adaptation reveals both curvature-polarity-selective and non-selective mechanisms [PDF]
, 2009 We have used a curvature after-effect, or CAE, to explore whether curvature detectors are tuned for the overall orientation of a curve. CAEs were measured for half-cycle cosine-shaped contours as a function of adaptor contour orientation for a fixed test

Surfaces of a Constant Negative Curvature
International Journal of Differential Equations, 2012 I study the geometric notion of a differential system describing surfaces of a constant negative curvature and describe a family of pseudospherical surfaces for the nonlinear partial differential equations with constant Gaussian curvature .

Neural decision boundaries for maximal information transmission. [PDF]
PLoS ONE, 2007 We consider here how to separate multidimensional signals into two categories, such that the binary decision transmits the maximum possible information about those signals.

Prescribing Gaussian curvature on $R^2$ [PDF]
Proceedings of the American Mathematical Society, 1997 The author derives a sufficient condition for a radially symmetric function \(K(x)\) which is positive somewhere to be a conformal curvature on \(\mathbb{R}^2\). In particular, it is shown that every nonnegative radially symmetric continuous function \(K(x)\) on \(\mathbb{R}^2\) is a conformal curvature. This is equivalent to the problem of solving the

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...
