Massive multiple-input-multiple-output (MIMO) is known as a large-scale antenna technology and has been enabled for the fifth generation (5G) mobile communication systems.The over-the-air (OTA) testing of massive MIMO antenna system has attracted a lot of attention in terms of evaluating the radio performance of a 5G base station (BS).As a promisin
Nearly a century ago, the liquid self-balancing device was first introduced by M.LeBlanc for passive balancing of turbine rotors.Although of common use in many types or rotating machines nowadays, little information is available on the unbalance response and stability characteristics of this handcuff device.Experimental fluid flow visualization evi
Overhead transmission line icing is one of the main factors affecting safety and reliability of power grid.This paper proposed an excitation deicing method of iced wire and theoretically revealed the ice removal mechanism under displacement excitation conditions, by taking the LGJ-70/10 glaze icing wire Cheater as the 3D model and analyzing and stu
In intelligent transportation systems, vehicle speed estimation plays a vital role in traffic monitoring, speed enforcement, and autonomous vehicles.Therefore, MAGNESIUM OIL the authors proposed a vehicle speed estimation method composed of pipelines: homography transformation using a deep image homography transformation network, vehicle detection
One of the entry mechanisms of the SARS-CoV-2 coronavirus into host cells involves endosomal acidification.It has been proposed that under acidic conditions, the fusion peptide proximal region (FPPR) of the SARS-CoV-2 spike glycoprotein acts as a pH-dependent switch, modulating immune response accessibility by influencing the positioning of the rec
