The role of cognitive processes in sleep disturbance: a comparison of Japanese and English university students [PDF]
, 2002 The present study investigated the role of cognitive processes in the maintenance of clinically significant sleep disturbance across two cultures. A questionnaire was administered to 60 Japanese and 60 English university students to assess the presence ...

Synchronization of Two Self-Synchronous Vibrating Machines on an Isolation Frame
Shock and Vibration, 2011 This paper investigates synchronization of two self-synchronous vibrating machines on an isolation rigid frame. Using the modified average method of small parameters, we deduce the non-dimensional coupling differential equations of the disturbance ...

Generalized Multi-kernel Maximum Correntropy Kalman Filter for Disturbance Estimation [PDF]
, 2023 Disturbance observers have been attracting continuing research efforts and are widely used in many applications. Among them, the Kalman filter-based disturbance observer is an attractive one since it estimates both the state and the disturbance ...

International Journal of Advanced Robotic Systems, 2017 In this article, we discuss the temperature regulation problem of robotic thermal tactile system under unknown time-varying disturbances. In order to improve the disturbance rejection property of the thermal system, a composite controller is presented ...

Generalized 𝑆(𝐶,𝐴,𝐵)-Pairs for Uncertain Linear Infinite-Dimensional Systems
Journal of Applied Mathematics, 2009 We introduce the concept of generalized 𝑆(𝐶,𝐴,𝐵)-pairs which is related to generalized 𝑆(𝐴,𝐵)-invariant subspaces and generalized 𝑆(𝐶,𝐴)-invariant subspaces for infinite-dimensional systems.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
