DOI: 10.1109/tvt.2022.3187710
Abstract: In this correspondence, we propose a new symbol-level quantized precoder design for massive multi-user multiple-input-single-output (MU-MIMO) systems employing low-resolution digital-to-analog converters (DACs) and phase-shift-keying (PSK) signaling. A new problem formulation based on the idea of… read more here.

DOI: 10.1186/s13104-020-05134-x
Abstract: Objective The assessment of clinical efficacy and toxicity is very important in pharmacology and toxicology. The effects of psychostimulants (e.g. amphetamine), psychotomimetics (e.g. Cannabis sativus) and snake antivenoms are sometimes unpredictable even at lower doses,… read more here.

DOI: 10.3928/01477447-20220217-05
Abstract: 3D-printed guides, which have recently been introduced in orthopedic oncology, improve resection accuracy compared with traditional bone resection methods, but there are inaccuracies associated with them. These inaccuracies could lead to disastrous outcomes such as… read more here.
