Medical Education, Volume 60, Issue 10, Page 1130-1142, October 2026.Abstract Introduction The transition from student to doctor represents a challenging shift in identity and responsibility that many graduates find difficult to manage. To understand better how to support the transition to practice we need an exploration of graduates' experiences that does not see the transition as a single moment, but a continuous ...

A Method of LQR Using Velocity Control for Unicycle Robot
Robotica & ManagementThis study explores the use of Linear Quadratic Regulator (LQR) control to stabilize a unicycle robot, a key example within the unicycle-type mobile robot category. Despite its inherent instability, the unicycle robot offers notable advantages over multi-wheeled, statically stable designs, including reduced spatial requirements due to its single ground

A Two Degree of Freedom Approach for Discrete‐Time Sliding Mode Control
International Journal of Robust and Nonlinear Control, Volume 36, Issue 13, Page 6540-6551, 10 September 2026.ABSTRACT This paper proposes a new two degree of freedom (2‐DOF) framework for discrete‐time sliding mode control (DSMC) that decouples the disturbed evolution from its nominal counterpart. The novel nominal/disturbed subsystem separation for DSMC can be used to define multiple closed‐loop specifications. The nominal regulation (or tracking) controller

Planning and Control for Autonomous Landing of Quadrotor Unmanned Aerial Vehicles With Disturbances
Engineering Reports, Volume 8, Issue 9, September 2026.This paper proposes a trajectory planning method for autonomous landing and designs a disturbance‐compensated nonlinear model predictive controller (NMPC) for environments under wind disturbances. An efficient trajectory planning method based on MINCO is proposed, which transforms the trajectory planning problem into an optimization problem.

Point and Risk estImation Using an enSemble of Models for Nowcasting: PRISM‐Now
Journal of Forecasting, Volume 45, Issue 6, Page 2760-2784, September 2026.ABSTRACT We propose PRISM‐Now, a novel ensemble forecasting system for near‐term GDP projection. Recognizing that relevant economic information evolves over time, we treat forecasts from multiple base models as draws from a mixture distribution of “good” and “bad” estimates, whose composition changes continuously and cannot be identified ex ante.
