Design of a 900 MHz Dual-Mode SWIPT for Low-Power IoT Devices
Sensors, 2019 This paper presents a duty cycle-based, dual-mode simultaneous wireless information and power transceiver (SWIPT) for Internet of Things (IoT) devices in which a sensor node monitors the received power and adaptively controls the single-tone or multitone

Arthritis &Rheumatology, EarlyView.Objective Systemic lupus erythematosus (SLE) shows clinical and molecular heterogeneity, and cardiovascular (CV) complications and lupus nephritis (LN) remain leading causes of morbidity and mortality. This study investigated whether omic profiling can reveal molecular endotypes linked to these outcomes.

An Enhanced Companding Algorithm for Universal Filtered Multi-Carrier System
ETRI JournalThis paper proposes a new companding scheme called three μ-law compand-ing to reduce the peak-to-average power ratio (PAPR) in a universal filtered multicarrier system. The proposed scheme is more flexible and provides better PAPR reduction and bit error
