This article presents a Kronecker-product (KP) beamforming approach incorporating sparse concentric circular arrays (SCCAs).The locations of the microphones on the SCCA are optimized concerning the broadband array directivity over a wide range of direction-of-arrival (DOA) deviations of a desired signal.A maximum directivity factor (MDF) sub-beamfo
New insights in the diagnosis of placenta accreta
In this case report we present a patient of 39 weeks pregnancy with vegas golden knights background a placenta accreta and discuss the new possilities of diagnosis of placental masses with respect to the related literature.The aim of our review was to assess the available useful procedures in an attempt to contribute to the decreasing the morbidity
Challenging clinical management of a patient with Gaucher disease type IIIC homozygous for the D409H mutation, aortic valve calcification and porcelain aorta
Background.Gaucher disease is a rare lysosomal storage disorder caused by glucocerebrosidase enzyme deficiency resulting in the cumulative deposition of glucocerebroside in macrophages, predominantly effecting bone marrow, liver and spleen.Gaucher disease type IIIC is a rare subtype that jeff rosenstock buffalo is characterized by cardiovascular in
Self-Templating Synthesis of N/P/Fe Co-Doped 3D Porous Carbon for Oxygen Reduction Reaction Electrocatalysts in Alkaline Media
The development of low-cost, highly active, and stable oxygen reduction reaction (ORR) catalysts is of great importance for practical applications in numerous energy conversion devices.Herein, iron/nitrogen/phosphorus co-doped carbon electrocatalysts (NPFe-C) with multistage porous structure were synthesized by the self-template method using melami
