Faces, Edges, Vertices of Some Polyhedra [PDF]
, 1974 A proof that: for any given polyhedron so shaped that every closed non-self intersecting broken line composed of edges of the polyhedron divides the surface of the polyhedron into precisely two disjoint regions each of which is bounded by the closed ...

An approach for line clipping against a convex polyhedron
Ruhuna Journal of Science, 2016 Line clipping operation is a bottleneck in most of computer graphics applications. There are situations when millions of line segments need to be clipped against convex polyhedrons with millions of facets.

The analytic continuation of volume and the Bellows conjecture in Lobachevsky spaces
, 2015 A flexible polyhedron in an n-dimensional space of constant curvature, namely, in the Euclidean space, or in the Lobachevsky space, or in the sphere, is a polyhedron with rigid (n-1)-dimensional faces and hinges at (n-2)-dimensional faces.

Advanced Science, EarlyView.Exclusive Se‐O coordination and Fe‐doping complementation significantly improve conductivity and modulate the d‐band centers, which strongly anchor polysulfides in bidirectional catalysis and reduce the energy barriers for the Li2S nucleation and dissociation, achieving high‐apacity retention, exceptional rate capability, and stable cycling capability.

Advanced Science, EarlyView.The transition between the spinel and rock‐salt phases induces irreversible structural changes in disordered LiNi0.5Mn1.5O4, thereby preventing it from fully releasing its electrochemical capacity during charge/discharge cycling. Abstract High‐voltage disordered spinel LiNi0.5Mn1.5O4 is a promising cathode material for high power density in lithium‐ion

Polygons of the Lorentzian plane and spherical simplexes
, 2013 It is known that the space of convex polygons in the Euclidean plane with fixed normals, up to homotheties and translations, endowed with the area form, is isometric to a hyperbolic polyhedron.

Advanced Science, EarlyView.Ultrathin oxide layer and ultraviolet absorbent are introduced into polyhedral oligomeric silsesquioxane (POSS) polyimide to improve the transmittance conservation and realize near zero mass loss against ultraviolet and atomic oxygen exposures. The POSS polyimide composite sealed triple‐junction GaAs thin‐film solar cell exhibits enhanced endurance of ...

Distributive Lattices, Polyhedra, and Generalized Flow
, 2008 A D-polyhedron is a polyhedron $P$ such that if $x,y$ are in $P$ then so are their componentwise max and min. In other words, the point set of a D-polyhedron forms a distributive lattice with the dominance order. We provide a full characterization of the
