Zariski Closed Algebras in Varieties of Universal Algebra

, 2014
The Zariski closure of an arbitrary representable (not necessarily associative) algebra is studied in the general context of universal algebra, with an application being that the codimension sequence is exponentially ...

Decomposing venture evaluation: Learning about belief formation

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Evaluating early‐stage ventures is difficult because observable signals of future quality are weak and noisy. How closely are evaluators' assessments related to venture quality, and do their subjective judgments add to the information already available about a venture?

A background-independent algebra in quantum gravity

Journal of High Energy Physics
We propose an algebra of operators along an observer’s worldline as a background-independent algebra in quantum gravity. In that context, it is natural to think of the Hartle-Hawking no boundary state as a universal state of maximum entropy, and to ...

An Innovative Approach to Multi‐Valued Logic

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The current generation of computer systems operates on the principles of binary logic, which encompasses both logical and arithmetic operations. However, silicon technology has reached its peak performance, prompting researchers to explore alternative methods for enhancing computational efficiency. One such method is the adoption of Multi‐Valued Logic (

Clinical decision thresholds for urine‐based fibroblast growth factor receptor (FGFR) testing across the bladder cancer care continuum: From molecular classification to treatment selection

UroPrecision, EarlyView.
Abstract Background Fibroblast growth factor receptor (FGFR) alterations are clinically actionable in urothelial cancer, yet tissue‐based molecular testing may fail when specimens are unavailable, depleted, aged, low in tumor content, or analytically inadequate.

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

Stability Modelling and Analysis of an Integrated Wind‐PV‐Storage Power System: A Small‐Signal Approach Using Multi‐Coordinate System Consistency Transformation

Energy Internet, EarlyView.
ABSTRACT With growing energy demand and depletion of fossil fuels, renewable energy development is crucial for achieving dual‐carbon goals. This paper focuses on small‐signal modelling and stability analysis of a grid‐connected wind‐PV‐storage system.

Lost in Aggregation: Quantifying Measurement Error from Geographic Centroids

Economic Record, EarlyView.
Due to privacy laws and regulations, microdata typically provide regional identifiers rather than exact coordinates. Researchers therefore often construct spatial variables from these aggregations, but the statistical implications depend on the research setting.

Koszul homomorphisms and universal resolutions in local algebra

Forum of Mathematics, Sigma
We define a local homomorphism $(Q,k)\to (R,\ell )$ to be Koszul if its derived fiber $R\otimes ^{\mathsf {L}}_Q k$ is formal, and if $\operatorname {Tor}^{Q}(R,k)$ is Koszul in the classical sense.

Transurethral ultrasound ablation (TULSA) for prostate cancer: a systematic review and meta‐analysis

BJU International, EarlyView.
Objective Our objective was to synthesise evidence on oncological, functional and safety outcomes of magnetic resonance imaging‐guided transurethral ultrasound ablation (TULSA) for primary and recurrent prostate cancer. Methods MEDLINE, Embase, Web of Science and Scopus were systematically searched from inception to July 2025. The primary outcomes were
