Stress tunable spin dynamics of a magnetic vortex under resonant magnetic fields by Xun Rao, Lele Peng, Weichao Yan, Yun Shen, Xiaohua Deng, Guohong Dai

“…Specifically, tensile stress induces a buckling state, facilitating the transition from the parallel spin to the vortex state in smaller disks and introducing a distinct kink in the hysteresis loop. Conversely, compressive stress causes the disappearance of the original intermediate state in larger disks, leading to a smoother hysteresis loop. …”

Adaptive Sliding Mode Control of Mobile Manipulators with Markovian Switching Joints by Liang Ding, Haibo Gao, Kerui Xia, Zhen Liu, Jianguo Tao, Yiqun Liu

“…Adaptive parameter techniques are adopted to cope with the effect of Markovian switching and nonlinear dynamics uncertainty and follow the desired trajectory for wheeled mobile manipulators. The resulting closed-loop system is bounded in probability and the effect due to the external disturbance on the tracking errors can be attenuated to any preassigned level. …”

Comment pense le jeu vidéo ? by Martin RINGOT

“…Videogames are interactive works, which means that their meaning is actualized when the software is played. With the interactive loop, the player contributes to reorganize in an always new way the different narrative elements, but it is above all the gameplay which allows the videogames to produce a constant thought they let the interactor get thanks to a feedback.…”
