Single IGBT Open‐Circuit Fault Mitigation in Cascaded Converters Using Zero‐Mode Control and Half‐Wave Reconfiguration Composite Control

open access: yesEnergy Science &Engineering, Volume 13, Issue 12, Page 6497-6511, December 2025.
STEP1:Analyze the differential characteristics of four IGBT open‐circuit faults in the H‐bridge module. STEP2:Analyze the impact of different IGBT faults on PWM voltage within a switching cycle. STEP3:Establish a hierarchical and collaborative fault‐tolerant control system: The zero‐mode control strategy dynamically switches modes according to the ...

Internal and External Sources of Nonprofit Innovativeness: A Configurational Approach

open access: yesNonprofit Management and Leadership, Volume 36, Issue 2, Page 257-270, Winter 2025.
ABSTRACT Using a configurational approach, this research explores how the complex interrelationships among four organizational factors—board size, board involvement, centralization, and government funding—influence organizational innovation. Based on survey and archival data from 44 U.S.

Reality Check on Formal Methods in Industry: A Study of Verum Dezyne

open access: yesJournal of Software: Evolution and Process, Volume 37, Issue 12, December 2025.
ABSTRACT Many of the classical questions reflecting the actionable use of formal methods in the software industry—“do they scale?” or “are they easily integrated?”—remain without a definitive answer, with many potentially adoptable formal notations being exploited in industry, but in a rather stove‐piped and siloed fashion, and with rather few ...

A categorical interpretation of continuous orbit equivalence for partial dynamical systems

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 12, Page 3637-3656, December 2025.
Abstract We define the orbit morphism of partial dynamical systems and prove that an orbit morphism being an isomorphism in the category of partial dynamical systems and orbit morphisms is equivalent to the existence of a continuous orbit equivalence between the given partial dynamical systems that preserves the essential stabilisers. We show that this

Hom ω$\omega$‐categories of a computad are free

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 6, December 2025.
Abstract We provide a new description of the hom functor on weak ω$\omega$‐categories, and show that it admits a left adjoint that we call the suspension functor. We then show that the hom functor preserves the property of being free on a computad, in contrast to the hom functor for strict ω$\omega$‐categories.

The six operations in topology

open access: yesJournal of Topology, Volume 18, Issue 4, December 2025.
Abstract In this paper, we show that the six functor formalism for sheaves on locally compact Hausdorff topological spaces, as developed, for example,‐ in Kashiwara and Schapira's book Sheaves on Manifolds, can be extended to sheaves with values in any closed symmetric monoidal ∞$\infty$‐category which is stable and bicomplete. Notice that, since we do
