DICTIONARY-LEARNING (DL)-BASED SPARSE CSI ESTIMATION IN MULTIUSER TERAHERTZ (THZ) HYBRID MIMO SYSTEMS UNDER HARDWARE IMPAIRMENTS AND BEAM-SQUINT EFFECT

Dictionary-Learning (DL)-Based Sparse CSI Estimation in Multiuser Terahertz (THz) Hybrid MIMO Systems Under Hardware Impairments and Beam-Squint Effect

This work conceives dictionary-learning (DL)-based sparse channel estimation schemes for multi-user Terahertz (THz) hybrid MIMO systems incorporating also non-idealities such as hardware impairments and beam-squint effect.Due to the presence of large antenna arrays coupled with frequency selectivity, beam squint effect is significant in THz systems

Long Pentraxin 3 as a Broader Biomarker for Multiple Risk Factors in End-Stage Renal Disease: Association with All-Cause Mortality

Persistent inflammation in end-stage renal disease (ESRD) patients is known to underlie the progression of chronic kidney disease and to be associated with multiple risk factors including malnutrition, atherosclerosis, and cardiovascular disease (CVD).The acute-phase protein pentraxin 3 (PTX3) has a proven potential as a local inflammatory biomarke
