A novel FPGA-based time-to-digital converter featuring machine learning-aided self-calibration

open access: yesIntelligent Systems with Applications
Time-to-digital converters (TDCs) implemented on Field-Programmable Gate Arrays (FPGAs) encounter significant challenges in achieving high precision. Unlike Application-Specific Integrated Circuits, FPGA-based TDCs must depend on standard logic elements ...

Determinants of undergraduate bioscience engagement: Validating attendance barriers and classroom spatial behaviour across institutions

open access: yesFEBS Open Bio, EarlyView.
Student engagement extends beyond simple attendance. Across 891 bioscience students from three universities, attendance behaviour was associated mainly with structural influences, whereas classroom spatial behaviour reflected affective and sensory factors.

A Digital-to-Time Converter for Time-Mode Successive-Approximation Register Analog-to-Digital Converters [PDF]

open access: yes, 2021
<p>The 8-bit digital-to-time converter (DTC) to be used for a time-mode successive-approximation register analog-to-digital converter (SAR ADC) with a minimum power consumption and silicon area is presented. The architecture and the drawbacks of a conventional voltage-mode SAR ADC are discussed. The principle of time-mode circuits and benefits of

Dactolisib outperforms Rapamycin in potentiating apoptosis induced by XPO1, Bcl‐2 and Mcl‐1 blockade in preclinical glioblastoma models

open access: yesFEBS Open Bio, EarlyView.
The PAM pathway and its impact on cellular metabolism. Color‐coded key symbols represent Rapamycin (R, orange, targeting mTOR) and Dactolisib (D, green, targeting PI3K/mTOR), indicating their sites of action. Created with BioRenders.com. Glioblastoma resists therapy through interconnected survival programs.
