Electric mobility has gained more attention within the transportation sector, where the development of innovative EV chargers must accomplish with the requirement of reduced charging times. Therefore, the implementation of more efficient and faster EV chargers is of utmost importance. This paper presents a comprehensive comparison between two topologies of three-phase AC-DC power converters: a full-bridge and a...
Introduction: Carotid body tumours (CBT) are rare paragangliomas for which surgical resection is still the recommended treatment. Frequently they are a benign disorder, discovered as asymptomatic neck masses located at the carotid bifurcation. Preoperative embolization has been used to decrease tumor volume, intraoperative blood loss and nerve injuries.There is however still much controversy and some studies ar...
Introduction: Over the past few decades management options of the acute limb ischaemia (ALI) have changed. Nowadays, catheter direct thrombolysis (CDT) is commonly used as an alternative to surgery in immediate management of the ALI and may offer certain advantages over surgery in appropriately selected patients. Objective: To evaluate CDT data for the treatment of acute ischaemia in lower extremity in differen...

The power distribution grid is centrally managed concerning the requirements of the end-users, however, with the appearance of smart grids, new technologies arc arising. Therefore, distributed energy resources, mainly, renewables, energy storage systems, electric mobility, and power quality are viewed as encouraging contributions for improving power management. In these circumstances, this paper presents a powe...
Interleukin-7 receptor α (encoded by IL7R) is essential for lymphoid development. Whether acute lymphoblastic leukemia (ALL)-related IL7R gain-of-function mutations can trigger leukemogenesis remains unclear. Here, we demonstrate that lymphoid-restricted mutant IL7R, expressed at physiological levels in conditional knock-in mice, establishes a pre-leukemic stage in which B-cell precursors display self-renewal a...
