A new symmetric modular eleven‐level inverter using single and double source unit for low voltage applications with reduced number of switches

IET Power Electronics, EarlyView., 2023
This study introduces a new modular multilevel inverter that can produce five levels of positive voltage using only six power switches and five DC voltage sources. The basic unit is composed of a single‐ and double‐source (SDS) unit. SDS reduces the number of power electronic components, such as the insulated gate bipolar transistors, freewheeling ...

Enhancing Volatility Prediction: A Wavelet‐Based Hierarchical Forecast Reconciliation Approach

Journal of Forecasting, EarlyView.
ABSTRACT Forecasting realized volatility (RV) has been widely studied, with numerous techniques developed to enhance predictive accuracy. Among these techniques, the use of RV decompositions based on intraday asset returns has been applied. However, the use of a frequency‐based decomposition, which provides unique insights into the dynamics of RV ...

Sustainable Work and Employment in Social Care: New Challenges, New Priorities

Human Resource Management, EarlyView.
ABSTRACT Human Resource Management (HRM) research focused on social care is sparse. This gap is surprising given the scale of the social care workforce in many countries, its vital role in meeting the increasingly complex needs of vulnerable community groups, and the persistent challenges in recruiting and retaining staff.

Elucidating the origin of open‐circuit voltage in ternary organic solar cells with a nonfullerene and a fullerene acceptor

InfoMat, EarlyView.
Fullerenes tend to alloy with polymer:nonfullerene acceptor hosts, yielding composition‐dependent increases in open‐circuit voltage while recombination remains governed by the charge‐transfer state energy and is independent of the nature of the third component.

A Comparative Study of Ultrasonography and CT Venography in the Diagnosis of Budd‐Chiari Syndrome

Journal of Clinical Ultrasound, EarlyView.
Budd‐Chiari syndrome (BCS) is characterized by hepatic venous outflow obstruction from the hepatic veins to the junction of the inferior vena cava (IVC) and right atrium. Ultrasound (US) and CT venography (CTV) are used as imaging techniques for the diagnosis of BCS, and We compared the diagnostic efficacy of the two modalities. The results showed that
