Second-order texton feature extraction and pattern recognition of building polygon cluster using CNN network

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
The cluster patterns of features in map space represent a comprehensive reflection of individual feature geometric attributes and their spatial adjacency relationships.

Examples, Counterexamples, and Enumeration Results for Foldings and Unfoldings between Polygons and Polytopes [PDF]

open access: yes
We investigate how to make the surface of a convex polyhedron (a polytope) by folding up a polygon and gluing its perimeter shut, and the reverse process of cutting open a polytope and unfolding it to a polygon.

Development of a Human 3D Immune‐Competent Neurovascular Model Enabling Time‐Resolved Monitoring of Neuroinflammatory Dynamics and Neuroimmune Interactions

open access: yesAdvanced Science, EarlyView.
Neuroinflammation alters blood–brain barrier integrity and contributes to neurological disorders, yet existing models lack human immune complexity. This study presents a 3D, immune‐responsive platform that reconstructs key neurovascular components and enables real‐time monitoring.

Periodic Solutions for Circular Restricted -Body Problems

open access: yesAbstract and Applied Analysis, 2013
For circular restricted -body problems, we study the motion of a sufficiently small mass point (called the zero mass point) in the plane of equal masses located at the vertices of a regular polygon. By using variational minimizing methods, for some , we

Polygonal patches of high order continuity [PDF]

open access: yes
A polygonal patch is defined to fill an n-sided hole within a rectangular Ck patch framework. First a reparameterization of the surface around the hole is constructed, that is defined outside a regular polygon.

Wavefront Line‐Scan Imaging Via a Single‐Pixel Detector

open access: yesAdvanced Science, EarlyView.
We propose and demonstrate a wavefront line‐scan imaging paradigm that integrates 1D spatial light modulation with single‐pixel detection. Benefiting from 1D modulation, not only is the imaging speed improved, but also the storage of modulation patterns is reduced by several orders of magnitude.
