A diagnosing method for phased antenna array element failures is proposed.The element excitation amplitudes and phases are reconstructed by a compressed sensing based approach, in which the radiated electric fields of the array are sampled by a single fixed receiving antenna.The diagnosing can be processed when the phased array is still in service.
Abstract Objectives It is essential to understand the molecular basis of ovarian cancer etiology and tumor development to provide more effective preventive and therapeutic approaches to reduce mortality.Particularly, the molecular targets and pathways involved in early malignant transformation are still not clear.Pro-inflammatory lipids and pathway
Orchids have evolved flowers with unique morphologies through coevolution with pollinators, such as insects.Among the floral verona wig organs, the lip (labellum), one of the three petals, exhibits a distinctive shape and plays a crucial role in attracting pollinators and facilitating pollination in many orchids.The lip of the terrestrial orchid Ha
Virtual Synchronous Generator (VSG) control technique is a potent solution to the issue of insufficient inertia in power systems.To address the challenges of low inertia and low output impedance in microgrids, this paper proposes a VSG frequency distributed collaborative secondary control strategy and develops a distributed active power sharing con
