Chimera

Chimera or not chimera?

The article entitled " Evidence for Cardiomyocyte Repopulation by Extracardiac Progenitors in Transplanted Human Hearts " by Laflamme et al, 1 published in Circulation Research, confirms our early observations 2 that cardiac chimerism occurs after transplanta-tion of a female heart in a male patient. These results are also in agreement with the detection of chimerism in multiple organs after bo...

Chimera and globally clustered chimera: impact of time delay.

Following a short report of our preliminary results [Sheeba, Phys. Rev. E 79, 055203(R) (2009)], we present a more detailed study of the effects of coupling delay in diffusively coupled phase oscillator populations. We find that coupling delay induces chimera and globally clustered chimera (GCC) states in delay coupled populations. We show the existence of multiclustered states that act as link...

Polypill: chimera or reality?

The idea of including several drugs in a fixed-dose combination for cardiovascular prevention was born at the beginning of this century. Although the suggestion initially received scant attention, the seminal work of Wald and Law in 2003, which introduced the term polypill, attracted the interest of researchers and the media, sparking a controversy that continues today. For some health professi...

Supernova Simulation with CHIMERA

CHIMERA is a multi-dimensional radiation hydrodynamics code designed to study core-collapse supernovae. The code is made up of three essentially independent parts: hydrodynamics, nuclear burning, and a neutrino transport solver combined within an operator-split approach. The multi-physics nature of the problem, and the specific implementation of that physics in CHIMERA, provide a rather straigh...
