The power of linear programming for general-valued CSPs

open access: yes, 2014
Let $D$, called the domain, be a fixed finite set and let $\Gamma$, called the valued constraint language, be a fixed set of functions of the form $f:D^m\to\mathbb{Q}\cup\{\infty\}$, where different functions might have different arity $m$.

Distributed associative memories for high-speed symbolic reasoning [PDF]

open access: yes, 1996
This paper briefly introduces a novel symbolic reasoning system based upon distributed associative memories which are constructed from correlation matrix memories (CMM). The system is aimed at high-speed rule-based symbolic operations.

The minimal arity of near unanimity polymorphisms [PDF]

open access: yesMathematica Slovaca, 2019
Abstract Dmitriy Zhuk has proved that there exist relational structures which admit near unanimity polymorphisms, but the minimum arity of such a polymorphism is large and almost matches the known upper bounds. We present a simplified and explicit construction of such structures and a detailed, self–contained proof.

Interpolating Binary and Multivalued Logical Quantum Gates

open access: yesProceedings, 2017
A method for synthesizing quantum gates is presented based on interpolation methods applied to operators in Hilbert space. Starting from the diagonal forms of specific generating seed operators with non-degenerate eigenvalue spectrum one obtains for ...

Arity hierarchies

open access: yesAnnals of Pure and Applied Logic, 1996
For many extensions \(L\) of first-order logic considered for finite structures there is a natural notion of arity of a formula (e.g., the maximal arity of a bounded second-order variable in a formula of fixed-point logic). Denote by \(L^k\) the fragment of \(L\) consisting of the sentences of \(L\) of arity \(\leq k\).

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Pole‐arity

open access: yesEos, Transactions American Geophysical Union, 1995
It took 40,000 years of theoretical time, but it finally happened. In a three‐dimensional, dynamically consistent model of the convecting fluid core of the Earth, the geomagnetic pole reversed after 40 millennia. The model of the dynamo at the center of the Earth, which was developed by Gary Glatzmaier of Los Alamos National Laboratory and Paul Roberts

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition
