Analysis of vibration evolution and propagation characteristics due to mechanical degradation in transformer iron cores

High Voltage, EarlyView.
Abstract This study investigates vibration changes due to transformer core deterioration by monitoring core vibration, compression force and shell wall vibrations simultaneously. The transformer core operates in a compound environment of mechanical vibration and thermal ageing for extended periods, and the correlation mechanism between core structural ...

Surrogate modelling for ice accretion prediction on wind turbine blades based on support vector regression

IET Renewable Power Generation, EarlyView.
Proposing a solution to the threat of ice accretion on wind turbine blades in extreme cold weather, this study introduces surrogate modelling using support vector regression for accurate prediction. The surrogate model, rigorously evaluated for reliability, demonstrates that real‐time pitch angle adjustments, informed by both the model and ...

A Smithian Political Economy Approach for the Competition Law of the 21st Century

The Modern Law Review, EarlyView.
This study aims to show how a Smithian political economy approach could assist competition law in addressing the challenges of the 21st‐century economy. We revisit Smith's Wealth of Nations to provide a more nuanced understanding of his views, contrasting them with the prevailing libertarian interpretation called here ‘Chicago Smith’.

Quantum anomaly and effective field description of a quantum chaotic billiard(6) Approaches from mathematical science and quantum information, Chaos and Nonlinear Dynamics in Quantum-Mechanical and Macroscopic Systems)

Quantum anomaly and effective field description of a quantum chaotic billiard(6) Approaches from mathematical science and quantum information, Chaos and Nonlinear Dynamics in Quantum-Mechanical and Macroscopic Systems)
カオス的量子ビリヤード系の有効場理論を等エネルギー面上の場の理論の観点から考察する。準位の離散性を量子異常の観点から解釈することにより、拡散・バリスティック領域の有効場理論としてKac-Moody代数を導出でき、それが量子カオス系のWigner-Dyson相関に相応していることを示す。 この論文は国立情報学研究所の電子図書館事業により電子化されました。

Embracing the Perks of Faulty Roadmaps: A Literature Review of Sociological Perspectives on Budgeting*

Accounting Perspectives, EarlyView.
ABSTRACT This literature review provides an overview of sociological perspectives on budgeting. The organizational relevance of budgeting has made it the subject of many perspectives and comprehensive reviews. However, the “niche” of sociological budgeting research deserves more attention as it helps us understand how and why budgets thrive—not ...

Quantum Non-Escape Probability in Open Chaotic System : Lyapunov Exponent versus Periodic Orbits(4) Quantum chaos and semiclassical theory in molecular science and nuclear theory, Chaos and Nonlinear Dynamics in Quantum-Mechanical and Macroscopic Systems)

Quantum Non-Escape Probability in Open Chaotic System : Lyapunov Exponent versus Periodic Orbits(4) Quantum chaos and semiclassical theory in molecular science and nuclear theory, Chaos and Nonlinear Dynamics in Quantum-Mechanical and Macroscopic Systems)
我々は、古典的にカオティっクな開放量子系での滞在確率を半古典的に計算する。時間が十分経てば、次の一般的な結論を引けることができる:時刻tでの滞在確率は二つの項の競争となる:一つはリヤプノフ指数に特徴付けられている指数的な減少とその減少を抑える役割である周期が2tの周期軌道和の項である。 We calculate semiclassically the quantum non-escape probability in an open quantum system with chaotic classical limit. We shall show that for sufficiently large time, the decay of the non-escape probability at

A computational framework to characterize and compare the tonal repertoires of toothed whales

Methods in Ecology and Evolution, EarlyView.
Abstract Toothed whales, despite being one of the most acoustically specialized lineages of vertebrates, lack detailed vocal repertoire characterizations comparable to those of songbirds and primates. Current descriptions often lack standardization, limiting interspecies and intraspecies comparisons critical for understanding the contribution of ...

Mobilising the Entrepreneurial Self to Manage the Crisis: Community Group‐Buying during the Shanghai Lockdown

Antipode, Volume 57, Issue 3, Page 1148-1171, May 2025.
Abstract The COVID pandemic disrupted traditional entrepreneurial governance arrangements. When the state's action could not effectively govern society, the “entrepreneurial self” began to emerge and manage the crisis. Using Shanghai as a case study, this research examines the dynamics of “community group‐buying” during its city‐wide lockdown in 2022 ...

Customizable wave tailoring materials enabled by nonlinear bilevel inverse design [PDF]

arXiv
Passive transformation of waves via nonlinear systems is ubiquitous in settings ranging from acoustics to optics and electromagnetics. Passivity is of particular importance for responding rapidly to stimuli and nonlinearity enormously expands signal transformability compared to linear systems due to the breaking of superposition.
