Pediatric Blood &Cancer, EarlyView.ABSTRACT The medical burdens of sickle cell disease (SCD) and transfusion‐dependent β‐thalassemia (TDT) are chronic and cumulative, even in children. Yet the effects expand beyond medications and healthcare visits due to their impacts on school attendance, academic performance, and peer engagement.

Indoor Radio Channel Modeling at D-Band Frequencies
2022 16th European Conference on Antennas and Propagation (EuCAP), 2022 This paper presents indoor radio channel measurements and models at D-band frequencies. A Line-of-Sight (LOS) alpha-beta-gamma path loss model is created based on indoor measurements up to 8.5 m in a laboratory and office room, resulting in a floating intercept alpha of 34.2 dB, PL exponent beta 1.9 and frequency dependency gamma 1.9.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Heavy menstrual bleeding (HMB) is a common condition among adolescents and young adults (AYAs) and is the leading cause of iron deficiency anemia (IDA) in this population. Growing evidence suggests that social determinants of health (SDOH) influence menstrual bleeding patterns, access to care, and treatment. However, no studies have

D-Band Antenna and Array Designs for 5G Applications
2023 Joint European Conference on Networks and Communications & 6G Summit (EuCNC/6G Summit), 2023 This paper presents the design, manufacturing and characterization of a parasitic patch microstrip D-band antenna and a 16-element segmented antenna array on a multilayer printed circuit board (PCB) targeted for 5G applications. The antennas are manufactured using printed circuit board technology with semi-additive processing (mSAP) of conductors on a ...
