Specialising finite domain programs with polyhedra [PDF]
, 2000 A procedure is described for tightening domain constraints of finite domain logic programs by applying a static analysis based on convex polyhedra. Individual finite domain constraints are over-approximated by polyhedra to describe the solution space ...

Advanced Materials, EarlyView.Nanoscale metal–organic frameworks (MOFs) and nanocellulose composites have significant potential for the multi‐functional remediation of the environment. This review focused on the synthesis strategies (in situ growth, ex situ growth, and other approaches), typical forms (aerogel, hydrogel, beads, and membrane), and applications in the removal of ...

Advanced Materials, EarlyView.High‐entropy materials (HEMs), typically composed of five or more principal elements in near‐equimolar ratios, offer significant potential due to their unique properties. This review outlines the emergence and structural evolution of HEMs, followed by an in‐depth discussion of the elemental roles (active sites, promoters, or stabilizers) for water ...

Advanced Materials, EarlyView.This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Advanced Materials, EarlyView.A 3D/0D S‐scheme heterojunction photocatalyst is constructed by spatially confining ZnSe quantum dots within covalent organic framework (COF) porous cages, enabling coupled CO2 photoreduction and value‐added chemical synthesis. COF porous cages serve as nanoreactors, enriching reactant concentrations, and the S‐scheme heterojunction facilitates charge ...

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

Short proofs on the matching polyhedron
Journal of Combinatorial Theory, Series B, 1983 AbstractA short proof of Edmonds' matching polyhedron theorem and the total dual integrality of the associated system of linear inequalities, proved first by W. H. Cunningham and A. B. Marsh (Math. Programming Stud. 8 (1978), 50–72), is given.

Advanced Materials Interfaces, EarlyView.ZIF‐8@PAN nanofiber membrane with a core‐shell structure is produced via coaxial electrospinning for removing tetracycline antibiotics. The adsorption behavior under different conditions, kinetics, thermodynamics, and isotherm are studied. Adsorption mechanisms include electrostatic interactions, coordination, hydrogen bonding, and π–π interactions ...
