Positively curved Killing foliations via deformations
, 2018 We show that a compact manifold admitting a Killing foliation with positive transverse curvature fibers over finite quotients of spheres or weighted complex projective spaces, provided that the singular foliation defined by the closures of the leaves has

Advanced Biology, EarlyView.The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.

New insight into the Lectionary of Leipzig
Rasprave Instituta za Hrvatski Jezik i Jezikoslovlje, 2012 The paper presents new insight into the Lectionary of Leipzig (LL), a Cyrillic manuscript most probably dating from between 1560 and 1580. This insight primarily concern the results of an analysis of watermarks, which is particularly important as the ...

Homotopy invariance of cohomology and signature of a riemannian foliation
, 2017 We prove that any smooth foliation that admits a Riemannian foliation structure has a well-defined basic signature, and this geometrically defined invariant is actually a foliated homotopy invariant.

Beyond Order: Perspectives on Leveraging Machine Learning for Disordered Materials
Advanced Engineering Materials, EarlyView.This article explores how machine learning (ML) revolutionizes the study and design of disordered materials by uncovering hidden patterns, predicting properties, and optimizing multiscale structures. It highlights key advancements, including generative models, graph neural networks, and hybrid ML‐physics methods, addressing challenges like data ...

Advanced Engineering Materials, EarlyView.Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Advanced Engineering Materials, EarlyView.In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Comparing Riemannian foliations with transversally symmetric foliations
Journal of Differential Geometry, 1988 In this paper Riemannian foliations are compared with transversally homogeneous foliations, where the model transverse structure is of the type of an irreducible compact symmetric space G/K. The datum needed for this comparison is a connection in the normal bundle, having similar properties as the canonical connection in the case of a transversally ...
