PLoS Genetics, 2023 The most abundant form of RNA editing in metazoa is the deamination of adenosines into inosines (A-to-I), catalyzed by ADAR enzymes. Inosines are read as guanosines by the translation machinery, and thus A-to-I may lead to protein recoding.

Personnel Psychology, Volume 77, Issue 4, Page 1403-1440, Winter 2024.Abstract Managers' leadership style has a substantial impact on employee and organizational outcomes. In the present study, we consider the role of leaders’ chronological age in predicting followers’ perceptions of their leadership style. Whereas ample research uncovers relationships between individuals’ age and how these individuals are perceived by ...

IET Control Theory &Applications, Volume 18, Issue 10, Page 1275-1288, July 2024.The paper presents an analytical method to solve the optimal control problem for affine nonlinear systems with unknown drift dynamics. It introduces a new non‐quadratic cost function that considers input constraints and includes the cost of the feed‐forward component of the control law.

IET Control Theory &Applications, Volume 18, Issue 9, Page 1200-1209, June 2024.This paper explores two non‐linear control techniques for designing an effective control system for an omnidirectional autonomous mobile robot with four Mecanum wheels. Due to the unique wheel structure and four separate wheels, the robot has non‐linear dynamics and multiple inputs and outputs.

Predictors of turnover amongst volunteers: A systematic review and meta‐analysis
Journal of Organizational Behavior, Volume 45, Issue 3, Page 434-458, March 2024.Summary Volunteers represent a global workforce equivalent to 61 million full‐time workers. A significant decline in volunteering has highlighted the urgency to better understand and address turnover amongst volunteers. To address this, we conducted a systematic review and meta‐analysis of turnover amongst volunteers.
