The montane honeybee, Apis nuluensis, is adapted to the Mt. Kinabalu highlands of Borneo. We analyzed the phylogenetic position of this bee using three mitochondrial genes, 16S ribosomal RNA (16S) and cytochrome oxidases subunit 1 and 2 (CO1 and CO2). The earlier suggestion that A. nuluensis is closely related to A. cerana was supported. We showed that this(More)
We study the phase diagram of isotropic spin-1 models in the vicinity of the Uimin-Lai-Sutherland (ULS) model. This is done with the help of a level-one SU(3) Wess-Zumino-Witten model with certain marginal perturbations. We find that the renormalization group flow has infrared stable and unstable trajectories divided by a critical line on which the ULS(More)
