Arity Bounds in First-Order Incremental Evaluation and Definition of Polynomial Time Database Queries

open access: yes, 1998
After inserting a tuple into or deleting a tuple from a database, a first-order incremental evaluation system (or a “foies”) for a database query derives the new query answer by using a first-order query on the new database, the old answer, and perhaps ...

A∞-structures for Bott-Chern and Aeppli cohomologies

open access: yesComplex Manifolds
In this article, we introduce certain arity-3 operations on complex manifolds arising from homotopy transfer theory. Such operations are related to the triple ABCABC-Massey products from Bott-Chern to Aeppli cohomology. We present a package for computing

Closed‐loop Recycling of Sulfide Solid Electrolytes from Spent Solid‐State Sodium Batteries

open access: yesAdvanced Materials, EarlyView.
Closed‐loop recycling of sulfide solid electrolyte via a mild dissolution–recrystallization–thermal treatment process enables efficient recovery from spent all‐solid‐state sodium batteries. The regenerated material preserves the crystal structure, local coordination, and chemical states, maintaining high ionic conductivity, reduced interfacial ...

Targeted Modulation of d‐Band Center in MoS2 Interlayer With n‐Type Co/Fe Dopants Accelerating Sulfur Reaction Kinetics in Lithium‐Sulfur Batteries

open access: yesAdvanced Materials, EarlyView.
A targeted modulation of the MoS2 electronic structure is achieved via substitutional n‐type Co/Fe co‐doping. This strategy triggers S‐mediated d‐p hybridization, optimizing the binding affinity with polysulfides to establish a volcano‐shaped relationship between the d‐band center and catalytic activity.

Alternating Quantifiers in Uniform One-Dimensional Fragments with an Excursion into Three-Variable Logic [PDF]

open access: yesLogical Methods in Computer Science
The uniform one-dimensional fragment of first-order logic was introduced a few years ago as a generalization of the two-variable fragment to contexts involving relations of arity greater than two.

Every permutation CSP of arity 3 is approximation resistant

open access: yes, 2009
—A permutation constraint satisfaction problem (permCSP) of arity k is specified by a subset Λ ⊆ Sk of permutations on {1, 2,..., k}. An instance of such a permCSP consists of a set of variables V and a collection of constraints each of which is an ...
