The afterglow emission from a stratified jet in GRB 170817A

Autor: Cheng, K. F., Zhao, X. H., Zhang, B. B., Bai, J. M.

The afterglow of GRB 170817A has been detected for more than three years, but the origin of the multi-band afterglow light curves remains under debate. A classical top-hat jet model is faced with difficulties in producing a shallow rise of the afterg

The Synchrotron Polarization in Decaying Magnetic Field in Gamma-Ray Bursts

Autor: Cheng, K. F., Zhao, X. H., Bai, J. M.

Polarization can serve as a probe of the radiation mechanism and magnetic field (MF) configuration in gamma-ray bursts (GRBs). In the case of constant MF, the synchrotron polarization in the prompt phase of GRBs has been widely studied. In this paper

Influence of ecological momentary assessment study design features on reported willingness to participate and perceptions of potential research studies: an experimental study

Autor: Stefan Schneider, Joshua M Smyth, Dusti R Jones, Cheng K F Wen, Frank T Materia, Arthur Stone

Publikováno v: BMJ Open, Vol 11, Iss 7 (2021)

Objective Intensive ambulatory assessment, such as ecological momentary assessment (EMA), is increasingly used to capture naturalistic patient-reported outcomes. EMA design features (eg, study duration, prompt frequency) vary widely between studies,
