Transient Voltage Stability: A Review of Practical Criteria and Assessment Indices

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper delves into the concept of transient voltage stability, and analyzes global practical criteria to summarize a more adaptable three‐stage criterion. It also classifies and summarizes existing transient voltage stability assessment indices and highlights three key aspects in the future research of the indices.

Non-linear Lie conformal algebras with three generators

, 2007
We classify certain non-linear Lie conformal algebras with three generators, which can be viewed as deformations of the current Lie conformal algebra of sl_2.

Helical Path Tortuosity Model for Sandstone Formations: A Unified Approach Across Permeability Ranges

Geofluids, Volume 2025, Issue 1, 2025.
This study develops a helical path tortuosity model with formation‐specific parameterization to address the critical limitation of existing tortuosity models that typically excel within narrow permeability ranges. The model decomposes total tortuosity into three physically meaningful components: geometric tortuosity arising from flow path winding ...

Casimir eigenvalues for universal Lie algebra

, 2012
For two different natural definitions of Casimir operators for simple Lie algebras we show that their eigenvalues in the adjoint representation can be expressed polynomially in the universal Vogel's parameters $\alpha, \beta, \gamma$ and give explicit ...

Approximation properties of torsion classes

Bulletin of the London Mathematical Society, Volume 56, Issue 12, Page 3819-3828, December 2024.
Abstract We strengthen a result of Bagaria and Magidor (Trans. Amer. Math. Soc. 366 (2014), no. 4, 1857–1877) about the relationship between large cardinals and torsion classes of abelian groups, and prove that (1)the Maximum Deconstructibility principle introduced in Cox (J. Pure Appl. Algebra 226 (2022), no.

Supersymmetry of the Chiral de Rham Complex

, 2006
We present a superfield formulation of the chiral de Rham complex (CDR) of Malikov-Schechtman-Vaintrob in the setting of a general smooth manifold, and use it to endow CDR with superconformal structures of geometric origin.

On the equivalence of Lurie's ∞$\infty$‐operads and dendroidal ∞$\infty$‐operads

Journal of Topology, Volume 17, Issue 4, December 2024.
Abstract In this paper, we prove the equivalence of two symmetric monoidal ∞$\infty$‐categories of ∞$\infty$‐operads, the one defined in Lurie [Higher algebra, available at the author's homepage, http://math.ias.edu/~lurie/, September 2017 version] and the one based on dendroidal spaces.

Functional Data Analysis: An Introduction and Recent Developments

Biometrical Journal, Volume 66, Issue 7, October 2024.
ABSTRACT Functional data analysis (FDA) is a statistical framework that allows for the analysis of curves, images, or functions on higher dimensional domains. The goals of FDA, such as descriptive analyses, classification, and regression, are generally the same as for statistical analyses of scalar‐valued or multivariate data, but FDA brings additional

Supersymmetric Deformations of Maximally Supersymmetric Gauge Theories

, 2012
We study supersymmetric and super Poincar\'e invariant deformations of ten-dimensional super Yang-Mills theory and of its dimensional reductions.

Advanced quantum and semiclassical methods for simulating photoinduced molecular dynamics and spectroscopy

WIREs Computational Molecular Science, Volume 14, Issue 5, September/October 2024.
Controling molecular processes using light. Abstract Molecular‐level understanding of photoinduced processes is critically important for breakthroughs in transformative technologies utilizing light, ranging from photomedicine to photoresponsive materials. Theory and simulation play a crucial role in this task.
