Distributed Adaptive Bipartite Time-Varying Formation Control for Heterogeneous Unknown Nonlinear Multi-Agent Systems

open access: yesIEEE Access, 2021
This paper investigates the bipartite time-varying formation control problem for a class of heterogeneous unknown nonlinear multi-agent systems. This bipartite time-varying formation is composed of two sub-formations whose relationship is opposite.

Stock Overreaction Behaviour in Bursa Malaysia: Does the Length of the Formation Period Matter? [PDF]

open access: yes, 2011
This paper investigates whether stock overreaction behaviour in Malaysian stock market is sensitive to the length of the formation period. Using the basic framework of De Bondt and Thaler (1985), this study find that stock overreaction behaviour in this ...

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

The Escape of Ionizing Photons from OB Associations in Disk Galaxies: Radiation Transfer Through Superbubbles

open access: yes, 1999
By solving the time-dependent radiation transfer problem of stellar radiation through evolving superbubbles within a smoothly varying HI distribution, we estimate the fraction of ionizing photons emitted by OB associations that escapes the HI disk of our
