Measurement Techniques and Challenges of Wireless LC Resonant Sensors: A Review

IEEE Access, 2023
Wireless operation of $LC$ resonant sensors is based on magnetic coupling between two inductive coils, where the inductor of the sensor acts as a secondary coil for the magnetic coupling. An external reader coil is used as a primary coil to interrogate

A PVT-Tolerant, Curvature-Compensated CMOS Bandgap-Based Current Reference With Single-Point Batch Trim

IEEE Open Journal of the Solid-State Circuits Society
Traditional bandgap-based current references display various limitations. This includes large temperature coefficients (TCs) across process corners, necessitating costly trimming cycles, and area inefficiency for low current values (< $10~\mu $ A).

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Accuracy and User Acceptability of 24-hour Ambulatory Blood Pressure Monitoring by a Prototype Cuffless Multi-Sensor Device Compared to a Conventional Oscillometric Device

Blood Pressure, 2023
Objective 24-hour ambulatory blood pressure monitoring (24ABPM) is state of the art in out-of-office blood pressure (BP) monitoring. Due to discomfort and technical limitations related to cuff-based 24ABPM devices, methods for non-invasive and continuous
