We consider a multiuser downlink transmission from a base station with multiple antennas (MIMO) to mobile terminals (users) with a single antenna, using orthogonal frequency division multiplexing (OFDM).Channel conditions are reported by a feedback from users with limited rate, and the base station schedules transmissions and beamforms signals to u
Cor triatriatum Mixing Bowl is a rare congenital heart defect that is associated with an increased risk for developing atrial fibrillation.We report a case of a healthy 38-year-old man who presented in decompensated heart failure and atrial fibrillation with a rapid ventricular response.A transthoracic echocardiogram (TTE) demonstrated severe biven
Purpose: Due to the antimicrobial property, menthol have significant potential for food preservation and BAKING foodstuff shelf life improvement.Nevertheless, menthol instability, insolubility, and rapid crystallization in aqueous media make it unsuitable for used in food products.This work was aimed to prepare menthol-loaded nanostructured lipid c
Compared with the current gesture recognition system based on radio frequency identification technology, the single-tag non-contact gesture recognition system based on convolutional neural network proposed in this paper can maximize user experience.Without the need for the user to carry any equipment, a single tag and single antenna are used to ach
Atherosclerosis is mediated by various factors and plays an important pathological foundation for cardiovascular and cerebrovascular diseases.Abnormal vascular smooth muscle cells (VSMCs) proliferation and migration have an essential role in atherosclerotic lesion formation.Circular RNAs (circRNA) have been widely detected in different species and
