Stability Bounds for the Generalized Kadanoff‐Baym Ansatz in the Holstein Dimer

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Predicting real‐time dynamics in correlated systems is demanding: exact two‐time Green's function methods are accurate but often too costly, while the Generalized Kadanoff‐Baym Ansatz (GKBA) offers time‐linear propagation at the risk of uncontrolled behavior. We examine when and why GKBA fails in a minimal yet informative setting, the Holstein

Investigating Perceptions of the Eating Disorder Examination‐Questionnaire Among Undergraduate Students: A Qualitative Approach

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Quantitative methods that have evaluated the Eating Disorder Examination Questionnaire (EDE‐Q) have found consistent evidence that the original four‐factor structure does not replicate across diverse samples and genders. Emerging evidence in the broader psychology literature shows that qualitative methods can provide nuanced insight ...

Compound Line-Commutated Converter with Commutation Voltage Compensation and Power Consumption Capability for Commutation Failure Suppression

open access: yesCSEE Journal of Power and Energy Systems
To mitigate commutation failures (CFs) of a line-commutated converter based-high voltage direct current transmission system (LCC-HVDC), an evolved thyristor based full bridge sub-module (ET-FBSM) and a compound LCC (CLCC) topology are proposed with the ...

A New Shunt Capacitor-Commutated Converter for Reducing Commutation Failure Probability of HVDC Transmission and Converter Transformer Noise

open access: yesIEEE Access
The HVDC transmission system with a line-commutated converter is prone to commutation failure when connected to a weak AC grid and has disadvantages such as a large footprint of AC filters and high noise from the converter transformer.

Varieties of Local Implementation for Net Zero in China: Evidence From Three Cities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Since China updated its nationally determined contributions in 2021, achieving carbon peaking before 2030 and carbon neutrality before 2060—the so‐called “dual carbon” goals—has become the new guiding principle of China's climate governance. However, few studies have examined the implementation of China's dual carbon goals, particularly the ...

Exploring Belonging Through the Student Union: The Power of Familiar Faces and Comfortable Spaces

open access: yesNew Directions for Higher Education, EarlyView.
ABSTRACT Since their origin, college unions have played a significant role in fostering a sense of belonging and advancing the academic mission of colleges. However, published empirical studies remain scarce due to the focus of college union professionals’ work on both student development and facility operations.

Enforced but not Enacted: How Return‐to‐Office Policies Reshape Boundary Enactment, Work‐Location Volition, and Eudaimonic Wellbeing

open access: yesHuman Resource Management, EarlyView.
ABSTRACT HR faces a conundrum over how to organize hybrid working patterns given the pros and cons associated with conducting work across multiple domains. Many organizations are currently seeking to clarify and often increase the requirements for employee presence at employer premises, meaning studies are needed to better understand how HR should look
