Developmental Cell, 2015 Asymmetric localization of planar cell polarity (PCP) proteins is essential for tissue integrity, but how asymmetric localization is regulated during cell division is not known. In this issue of Developmental Cell, Shrestha et al. (2015) show that mitotic Polo-like kinase 1 (Plk1) links internalization of PCP proteins to cell-cycle progression.

The Dichotomy of Evaluating Homomorphism-Closed Queries on Probabilistic Graphs [PDF]
Logical Methods in Computer Science, 2022 We study the problem of query evaluation on probabilistic graphs, namely, tuple-independent probabilistic databases over signatures of arity two. We focus on the class of queries closed under homomorphisms, or, equivalently, the infinite unions of ...

Dual Univariate Interpolatory Subdivision of Every Arity: Algebraic Characterization and Construction [PDF]
Journal of Mathematical Analysis and Applications, 2019 A new class of univariate stationary interpolatory subdivision schemes of dual type is presented. As opposed to classical primal interpolatory schemes, these new schemes have masks with an even number of elements and are not step-wise interpolants.

Characteristic Sequence of Strongly Minimal Directed Single Graphs of 1-Arity
Computation, 2022 In this paper, we will classify the strongly minimal directed single graphs of 1-arity by axiomatizing the theory of characteristic sequence of such a graph. Then we will show this theory is complete by using Łos-Vaught test. Complete theory is important

Universal Horn Sentences and the Joint Embedding Property [PDF]
Discrete Mathematics & Theoretical Computer Science, 2022 The finite models of a universal sentence $\Phi$ in a finite relational signature are the age of a structure if and only if $\Phi$ has the joint embedding property. We prove that the computational problem whether a given universal sentence $\Phi$ has the

Relational Width of First-Order Expansions of Homogeneous Graphs with Bounded Strict Width [PDF]
, 2020 Solving the algebraic dichotomy conjecture for constraint satisfaction problems over structures first-order definable in countably infinite finitely bounded homogeneous structures requires understanding the applicability of local-consistency methods in ...

Higher arity self-distributive operations in Cascades and their cohomology [PDF]
, 2019 We investigate constructions of higher arity self-distributive operations, and give relations between cohomology groups corresponding to operations of different arities. For this purpose we introduce the notion of mutually distributive $n$-ary operations

Arity Shape of Polyadic Algebraic Structures [PDF]
Zurnal matematiceskoj fiziki, analiza, geometrii, 2017 Concrete two-set (module-like and algebra-like) algebraic structures are investigated from the viewpoint that the initial arities of all operations are arbitrary.

The arity gap of polynomial functions over bounded distributive lattices [PDF]
, 2009 Let A and B be arbitrary sets with at least two elements. The arity gap of a function f: A^n \to B is the minimum decrease in its essential arity when essential arguments of f are identified.

Improving the efficiency of GP-GOMEA for higher-arity operators [PDF]
Annual Conference on Genetic and Evolutionary ComputationDeploying machine learning models into sensitive domains in our society requires these models to be explainable. Genetic Programming (GP) can offer a way to evolve inherently interpretable expressions.
