Variance‐Empirical Mode Decomposition Method for Fault Detection in MMC‐HVDC Transmission Lines

Energy Science &Engineering, EarlyView.
A variance‐embedded empirical mode decomposition (VEMD) method is proposed for fast and accurate fault detection in MMC‐HVDC transmission lines. By combining variance analysis with EMD, the method reliably detects various faults without communication links and remains robust to noise and non‐fault transients.

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

How emerging market firms learn to lead in complex product systems: Evidence from China's civil aircraft industry

Global Strategy Journal, EarlyView.
Abstract Research Summary The rise of emerging market lead firms (LFs) in global value chains (GVCs) challenges the prevailing view that only multinational corporations (MNCs) from advanced economies lead systems integration, design, and innovation activities.

Further offshoring, nearshoring, and reshoring: Exploring the role of experience

Global Strategy Journal, EarlyView.
Abstract Research Summary This study examines the role of firms' experience in shaping strategic decisions to relocate offshored activities. Adopting an experiential learning perspective, we test the influence of two types of experience—international production experience and reshoring experience—on the choice of relocating to another foreign country ...

U.S. Multinational Corporations’ Initial Income‐Shifting Response to the TCJA

Journal of Corporate Accounting &Finance, EarlyView.
ABSTRACT I find U.S. multinational corporations (MNCs) responded to the Tax Cuts and Jobs Act (TCJA) of 2017 by increasing income shifted to foreign sources in the first two years following the effective date. Financially constrained MNCs increased income shifting more, while higher operational uncertainty MNCs increased income shifting less than other

Assessing the Performance of the Copernicus European Regional Reanalysis Dataset in Reproducing Extreme Weather Events in Poland

International Journal of Climatology, EarlyView.
Global reanalyses, for example ERA5 and ERA5‐Land, tend to misrepresent the local‐scale weather extremes due to the limited spatial resolution. In this paper CERRA shows clear and consistent improvements over ERA5 and ERA5‐Land in representing extreme temperature and precipitation in Poland, particularly for localized and short‐lived heavy rainfall ...
