In this article, share some our reflections experie...

This paper is to give an outline of the tree biotechnology research in South Korea. Tree Breeding, we call Traditional Tree Breeding later compared to Tree Biotechnology, started in 1954 in South Korea. Tree Biotechnology Research started as Tissue culture in the late 1970 in South Korea. Micropropagation was the first field adopted. Embryo culture, Bud culture, Callus culture, Cell culture are...

Gamma ray bursts (GRBs) are short and intense pulses of γ-rays arriving from random directions in the sky. Several years ago Amelino-Camelia et al. [1] (see also [2]) pointed out that a comparison of time of arrival of photons at different energies from a GRB could be used to measure (or obtain a limit on) possible deviations from a constant speed of light at high photons energies. I review her...

There are now in the literature two proposals of relativity theories with observer-independent scales of both velocity and length/mass: one, which we here call “DSR1”, proposed by Amelino-Camelia in gr-qc/0012051,hep-th/0012238 and one, which we here call “DSR2”, proposed by Magueijo and Smolin in hep-th/0112090. We argue that a key aspect of such theories are the kinematical conditions for par...
