Fuzzy Logic for Incidence Geometry [PDF]

open access: goldThe Scientific World Journal, 2016
The paper presents a mathematical framework for approximate geometric reasoning with extended objects in the context of Geography, in which all entities and their relationships are described by human language. These entities could be labelled by commonly

Incidence Geometry in a Weyl Chamber II: $SL_n$ [PDF]

open access: greenAdvances in Applied Mathematics, 2016
We study the central hyperplane arrangement whose hyperplanes are the vanishing loci of the weights of the first and the second fundamental representations of $\mathfrak{gl}_n$ restricted to the dual fundamental Weyl chamber. We obtain generating functions that count flats and faces of a given dimension.

Coherent Magnetization Rotation of a Layered System Observed by Polarized Neutron Scattering under Grazing Incidence Geometry [PDF]

open access: goldCrystals, 2019
The in-plane magnetic structure of a layered system composed of polycrystalline grains smaller than the ferromagnetic exchange length was studied to elucidate the mechanism controlling the magnetic properties considerably different from the bulk using ...

Point-hyperplane incidence geometry and the log-rank conjecture [PDF]

open access: greenACM Transactions on Computation Theory, 2021
We study the log-rank conjecture from the perspective of point-hyperplane incidence geometry. We formulate the following conjecture: Given a point set in ℝd that is covered by constant-sized sets of parallel hyperplanes, there exists an affine subspace ...

On incidence geometry [PDF]

open access: yesBulletin of the American Mathematical Society, 1940
The purpose of this note is to analyze the conditions needed in geometry to introduce ideal points without using order relations. Since only incidence relations are used, it is convenient to use the notation of lattice theory.

Ruled Surface Theory and Incidence Geometry [PDF]

open access: yes, 2017
This is an expository paper about applications of ruled surface theory in incidence geometry. It surveys the results that have been proven, gives an overview of the methods, and discusses some open problems and further directions. It will appear in the book Journey Through Discrete Mathematics, a Tribute to Jiri Matousek, edited by Martin Loebl ...

Critical ion velocities for nanostructure formation on metal surfaces by slow highly charged ions at arbitrary incidence angles [PDF]

open access: yesScientific Reports
Surface nanostructuring of metal targets induced by irradiation with slow, highly charged ions at various incidence angles is investigated. We extend our recently developed cohesive energy model to analyze the influence of impact geometry.

GIDVis: a comprehensive software tool for geometry-independent grazing-incidence X-ray diffraction data analysis and pole-figure calculations [PDF]

open access: hybridJournal of Applied Crystallography, 2019
GIDVis is a software package based on MATLAB which is specialized for the visualization and analysis of grazing-incidence thin-film X-ray diffraction data obtained during sample rotation around the surface normal. Using GIDVis, detector calibration, data

Association between left ventricular remodeling and coronary chronic total occlusion in hypertensive coronary artery disease patients [PDF]

open access: yesScientific Reports
Hypertensive left ventricular (LV) remodeling may influence coronary artery pathology due to anatomical proximity, yet its association with coronary chronic total occlusion (CTO) remains unclear. This cross-sectional, hypothesis-generating study included
