An Improved Sparrow Search Algorithm for the Optimization of Variational Modal Decomposition Parameters

open access: yesApplied Sciences
Variational modal decomposition (VMD) is frequently employed for both signal decomposition and extracting features; however, the decomposition outcome is influenced by the quantity of intrinsic modal functions (IMFs) and the specific parameter values of ...

Confinement‐Induced Enhancement of Solid‐State Emission Quantum Yield in Rubrene@MOF Hybrid Materials

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Pore‐size‐controlled nanoconfinement of rubrene within UiO‐66 and UiO‐67 suppresses aggregation‐caused quenching and restores bright solid‐state emission. Geometric exclusion and energetic destabilization prevent parallel stacking, yielding solution‐like absorption and fluorescence quantum yields up to 25%.

Re-definition of VMD and Necessary Elements

open access: yes, 2021
VMD(ビジュアルマーチャンダイジング)戦略は、リテールにおけるビジネスモデルの「マーチャンダイジングの視覚化」という概念で、購買のフックとして機能することがその目的と考えられてきた。しかし、ECでの購買が主流になり、リアル店舗は、「ショールーム」や「ネット販売の拠点」化していく今、VMDに必要なのは、購買行動の入口だけに留まらず、顧客心理に寄り添いカスタマージャーニーの全てに関わっていくことである。来店の理由を生み出し、期待をもって来店した顧客に新しい発見や体験を通して ...

Recognition of Spatiotemporal Feature Images of Zero‐Sequence Voltage for Single‐Phase High‐Impedance Ground Faults Under Complex Conditions

open access: yesHigh Voltage, EarlyView.
ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.

New 2D-Variational Mode Decomposition-Based Techniques for Seismic Attribute Enhancement

open access: yesApplied Sciences
Seismic attributes are widely used to enhance the interpretation of structural, stratigraphic, and lithologic features in subsurface data. Their effectiveness, however, can be limited by noise, resolution constraints, and processing artifacts. This study

Cytopathology Terminology Systems: European Federation of Cytological Societies Survey on Practice in Europe

open access: yesCytopathology, EarlyView.
Cytology terminologies are widely accepted within Europe based on EFCS survey. The Bethesda System for reporting cervical cytology and the Bethesda System for reporting thyroid cytopathology have been implemented by most of the responding countries. ABSTRACT Cytopathologists communicate with clinicians via cytopathology reports.
