Stratifying Quotient Stacks and Moduli Stacks [PDF]
Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X/H], where X is a projective scheme and H is a linear algebraic group with internally graded unipotent radical acting linearly on X, in such a way that each stratum [S/H] has a geometric quotient S/H ...

Stack-sorting with consecutive-pattern-avoiding stacks [PDF]
We introduce consecutive-pattern-avoiding stack-sorting maps $\text{SC}_σ$, which are natural generalizations of West's stack-sorting map $s$ and natural analogues of the classical-pattern-avoiding stack-sorting maps $s_σ$ recently introduced by Cerbai, Claesson, and Ferrari.

Sorting and preimages of pattern classes [PDF]
We introduce an algorithm to determine when a sorting operation, such as stack-sort or bubble-sort, outputs a given pattern. The algorithm provides a new proof of the description of West-2-stack-sortable permutations, that is permutations that are ...

Wear maps for TiC composite based coatings deposited on 303 stainless steel [PDF]
Dry sliding wear (pin-on-disc) tests were carried out under ambient conditions at room temperature for TiC coated and uncoated 303 stainless steel, using alumina as a counterface.

Effect of Cell Size on the Performance and Temperature Distribution of Molten Carbonate Fuel Cells
Molten carbonate fuel cells (MCFCs) are high-operating-temperature fuel cells with high efficiency and fuel diversity. Electrochemical reactions in MCFCs are exothermic.

Agentic AI in Cloud-Based Credit Card Fraud Detection: Towards Autonomous Risk Mitigation
Credit card fraud (CCF) still remains an ongoing concern for financial institutions because to the huge disparity between genuine and fraudulent transactions, as well as the ever-changing behavior of fraudsters. This paper proposes a cloud-based Agentic
