Decomposable approximations of nuclear C*-algebras [PDF]
We show that nuclear <i>C</i><sup>*</sup>-algebras have a refined version of the completely positive approximation property, in which the maps that approximately factorize through finite dimensional algebras are convex ...

TRIM: Simultaneous Thermometry, Ranging, and Imaging via a Monolithic Metalens
ABSTRACT While metasurfaces offer a pathway beyond the discrete architectures of conventional LWIR systems, physically fusing high‐precision thermometry and passive ranging onto a single metalens remains a formidable challenge. Here, we demonstrate a monolithic, dual‐focus metalens capable of simultaneous multidimensional sensing.

In order to measure the degree of dissimilarity between elements of a Boolean algebra, the author’s (1984) proposed to use pseudometrics satisfying generalizations of the usual axioms for identity.

A note on homomorphisms of Hilbert algebras
We give a representation theorem for Hilbert algebras by means of ordered sets and characterize the homomorphisms of Hilbert algebras in terms of applications defined between the sets of all irreducible deductive systems of the associated algebras.

Fascinating Number Sequences from Fourth Order Difference Equation Via Quaternion Algebras
The balancing and Lucas-balancing numbers are solutions of second order recurrence relations. A linear combination of these numbers can also be obtained as solutions of a fourth order recurrence relation.

After an introduction concerned with equivalence relations and the tower associated to them, the authors study some properties of \(G\)-relations (where \(G\) is a group) and connect them with the algebras \(A_n^G(d)\) (algebras that have a basis indexed by ``\(G\)-stable equivalence relations'').

Levels and sublevels of composition algebras
Lewis' and Leep's bounds on the level and sublevel of quaternion algebras are extended to the class of composition algebras. Some simple constructions of composition algebras of known level values are given.

Expanded‐graphite/graphene‐nanoplatelet hybrids deliver a near‐order‐of‐magnitude thermal‐conductivity enhancement in paraffin phase‐change materials. A microCT‐informed 3D modeling framework resolves the percolating EG backbone and captures sub‐voxel GNP enrichment, quantitatively linking microstructure to heat flow and revealing a graphene‐enabled ...

The characterization of Nelson algebras by Sheffer stroke
In this study, Sheffer stroke Nelson algebras (briefly, s-Nelson algebras), (ultra) ideals, quasi-subalgebras, quotient sets, and fuzzy structures on these algebraic structures are introduced.
