On surface-minimizing polyhedral decompositions
The author shows under certain conditions that the minimal surface, decomposing a given polyhedron into parts of given volumes, is not polyhedral and lists some characteristic local properties of the optimal polyhedral decomposition, assuming such decomposition exists, of a given polyhedron with a given volume. A cell system defined by the shortest net

This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Bicubic Splines for Fast-Contracting Control Nets
Merging parallel quad strips facilitates narrowing surface passages, and allows a design to transition to a simpler shape. While a number of spline surface constructions exist for the isotropic case where n pieces join, few existing spline constructions ...

Programmable Carrier‐Free All‐Enzyme Beads for Modular Continuous‐Flow Biocatalysis
Genetically encoded enzyme building blocks self‐assemble into monodisperse, carrier‐free protein beads via a droplet‐based formulation strategy. These programmable catalytic particles enable modular continuous‐flow biocatalysis, from single‐enzyme reactions to multi‐enzyme cascades and bead–bead coupled reactor systems.

Geometry and forming of the polyhedral Box tYpe surfaces on base cyclic surface
The article concerns the questions of the formation of the thin-walled constructions with cross sections in the form of polyhedral. The bases of such constructions are cyclic surfaces with some line of the centers and the law of change of the radius of ...

PERFORMANCE INVESTIGATION FOR NANOCARBON MODIFIED DISPENSER CATHODE
The article provides characteristics of dispenser cathodes with admixture of nanocarbon particles, i.e. sulfoadduct of carbon nanoclusters (Ugleron®), into active material and polyhedral multilayer carbon nanostructures of the fulleroid type and ...

Polyhedral Surfaces of High Genus [PDF]
The construction of the COMBINATORIAL data for a surface with n vertices of maximal genus is a classical problem: The maximal genus g=[(n-3)(n-4)/12] was achieved in the famous ``Map Color Theorem'' by Ringel et al. (1968). We present the nicest one of Ringel's constructions, for the case when n is congruent to 7 mod 12, but also an alternative ...

Coating stent materials with polyhedral oligomeric silsesquioxane-poly(carbonateurea)urethane nanocomposites [PDF]
The long-term efficacy of coronary or peripheral stenting is limited by in-stent restenosis (ISR), which occurs in 15 to 30% of patients and is attributed primarily to neointimal hyperplasia.

Blown-up toric surfaces with non-polyhedral effective cone [PDF]
We construct projective toric surfaces whose blow-up at a general point has a non-polyhedral pseudo-effective cone. As a consequence, we prove that the pseudo-effective cone of the Grothendieck–Knudsen moduli space \bar{M_{0,n} of stable rational ...
