A 13-level switched-capacitor-based multilevel inverter with reduced components and inrush current limitation.

This paper proposed a hybrid switched-capacitor inverter to reduce the number of components and achieve automatic capacitor balancing. The proposed structure combines a switched capacitor (SC) unit with a flying capacitor (FC). Significant advantages of the proposed design include a reduced number of components, simple control, voltage boosting capability, and limitation of the inrush current during capacitor charging.

Investigating the outcomes of full thickness skin graft in the reconstruction of concealed penis in children aged 7 to 14 years.

Introduction: Concealed penis is a congenital anomaly that affects not only the appearance but also the function of the external genitalia in the male sex. Different surgical methods have been proposed to correct this disorder, including removal of the previous scar, penile shaft, penile trunk skin reconstruction with flap, penile skin fixation in penopubic and penoscrotal angles, and removal of extra pubic fat. In this study, we will discuss the results of definitive surgery in one stage using autogenous skin grafts and examine the details of this technique.

Cardiac Tumor with Dual Component of Myxoma and Angiofibroma Presented with Syncope: An Extremely Rare Case Report.

Background: Primary cardiac tumors (PCT), such as myxoma, are rare and predominantly benign. Angiofibroma tumors are an extremely rare subtype of PCT, reported in less than ten cases. In this study, we presented a mixed tumor of myxoma and angiofibroma for the first time in the human heart.

Using artificial intelligence to predict post-operative outcomes in congenital heart surgeries: a systematic review.

Introduction: Congenital heart disease (CHD) represents the most common group of congenital anomalies, constitutes a significant contributor to the burden of non-communicable diseases, highlighting the critical need for improved risk assessment tools. Artificial intelligence (AI) holds promise in enhancing outcome predictions for congenital cardiac surgery. This study aims to systematically review the utilization of AI in predicting post-operative outcomes in this population.
