Reconfigurable intelligent surfaces (RIS) are passive controllable arrays of small reflectors that direct electromagnetic energy towards or away from the target nodes, thereby allowing better management of signals and interference in a wireless network.The RIS has the potential for significantly improving the performance of wireless networks.Unfort
Introduction:Hemangiomas are benign vascular lesions frequently observed in infancy and childhood.Case Report:A 14-year-old boy was referred to the hospital with a left-sided ear canal mass and hearing impairment.Otoscopic examination revealed a mass that occluded the canal.The transcanal surgical excision was performed.The mass was dissected from
The chirality Tendon quantification is of great importance in structural biology, where the differences in proteins twisting can provide essentially different physiological effects.However, this aspect of the chirality is still poorly studied for helix-like supramolecular structures.In this work, a method for chirality quantification based on the c
