Weighted omega-Restricted One Counter Automata [PDF]

Logical Methods in Computer Science, 2018
Let $S$ be a complete star-omega semiring and $\Sigma$ be an alphabet. For a weighted $\omega$-restricted one-counter automaton $\mathcal{C}$ with set of states $\{1, \dots, n\}$, $n \geq 1$, we show that there exists a mixed algebraic system over a ...

From Words to Wood: Text‐to‐Procedurally Generated Wood Materials

Computer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract In the domain of wood modeling, we present a new complex appearance model, coupled with a user‐friendly NLP‐based frontend for intuitive interactivity. First, we present a procedurally generated wood model that is capable of accurately simulating intricate wood characteristics, including growth rings, vessels/pores, rays, knots, and figure ...

On implementation of Stickel's key exchange protocol over max-min and max-T semirings

Journal of Mathematical Cryptology
Given that the tropical Stickel protocol and its variants are all vulnerable to the generalized Kotov–Ushakov attack, we suggest employing the max-min semiring and, more generally, max-TT semiring where the multiplication is based on a TT-norm, as a ...

New building blocks for F1${\mathbb {F}}_1$‐geometry: Bands and band schemes

Journal of the London Mathematical Society, Volume 111, Issue 4, April 2025.
Abstract We develop and study a generalization of commutative rings called bands, along with the corresponding geometric theory of band schemes. Bands generalize both hyperrings, in the sense of Krasner, and partial fields in the sense of Semple and Whittle.

Derivation dα,β of ordered G-semirings [PDF]

Mathematica Moravica, 2018
In this paper, we introduce the concept of derivation dα,β of ordered G-semiring. We study some of the properties of derivation dα,β of ordered G-semirings.

Semiring Provenance for B\"uchi Games: Strategy Analysis with Absorptive Polynomials [PDF]

Logical Methods in Computer Science
This paper presents a case study for the application of semiring semantics for fixed-point formulae to the analysis of strategies in B\"uchi games. Semiring semantics generalizes the classical Boolean semantics by permitting multiple truth values from ...

Integrating amyloid imaging and genetics for early risk stratification of Alzheimer's disease

Alzheimer's &Dementia, Volume 20, Issue 11, Page 7819-7830, November 2024.
Abstract INTRODUCTION Alzheimer's disease (AD) initiates years prior to symptoms, underscoring the importance of early detection. While amyloid accumulation starts early, individuals with substantial amyloid burden may remain cognitively normal, implying that amyloid alone is not sufficient for early risk assessment.

Valuations of semirings

Journal of Pure and Applied Algebra, 2018
We develop notions of valuations on a semiring, with a view toward extending the classical theory of abstract nonsingular curves and discrete valuation rings to this general algebraic setting; the novelty of our approach lies in the implementation of hyperrings to yield a new definition (\emph{hyperfield valuation}).

Fire exclusion alters forest evapotranspiration: A comprehensive water budget analysis in longleaf pine woodlands

Ecological Monographs, Volume 94, Issue 4, November 2024.
Abstract Forests are critical to water resources, but high evapotranspiration (ET) can reduce water yield. Thinning and prescribed fire reduce forest density and often reduce ET, promoting higher water yield. However, results from such treatments have been inconsistent, possibly because of unknown interactions among individual ET components. We compare

Left Zeroid and Right Zeroid Elements of Γ-Semirings

Discussiones Mathematicae - General Algebra and Applications, 2017
In this paper we introduce the notion of a left zeroid and a right zeroid of Γ -semirings. We prove that, a left zeroid of a simple Γ-semiring M is regular if and only if M is a regular Γ -semiring.
