Constraints on the neutrino mass and mass hierarchy from cosmological observations
Considering the mass splitting between three active neutrinos, we represent
the new constraints on the sum of neutrino mass by updating the
anisotropic analysis of Baryon Acoustic Oscillation (BAO) scale in the CMASS
and LOWZ galaxy samples from Data Release 12 of the SDSS-III Baryon Oscillation
Spectroscopic Survey (BOSS DR12). Combining the BAO data of 6dFGS, MGS, LOWZ
and CMASS with ~2015 data of temperature anisotropy and
polarizations of Cosmic Microwave Background (CMB), we find that the
C.L. upper bounds on refer to eV for
normal hierarchy (NH), eV for inverted hierarchy
(IH) and eV for degenerate hierarchy (DH)
respectively, and the normal hierarchy is slightly preferred than the inverted
one (). In
addition, the additional relativistic degrees of freedom and massive sterile
neutrinos are neither favored at present.Comment: 12 pages, 3 tables, 1 figure; refs adde

Distribution and Permeability of Capillaries at the Skin of the Conception Vessel and the Governor Vessel in Healthy Rabbits
ObjectiveTo investigate the distribution and permeability of blood vessels on the Conception Vessel and the Governor Vessel in the physiological state.MethodsEvans blue (EB) solution was injected into the marginal ear vein of healthy rabbits. Three hours after injection, the rabbits were sacrificed and the skin on the Conception Vessel and the Governor Vessel and the corresponding bilateral non-channels was collected. EB was extracted with 7:3 acetone: physiological saline, and the absorbance of EB at each skin tissue was measured with a spectrophotometer.ResultsThe A value of EB absorbance at the Conception Vessel on the abdominal skin was lower than that of the corresponding bilateral non-channels with a statistically significant difference (P<0.01). The A value of EB absorbance at the Governor Vessel on the back was higher than that of the corresponding bilateral non-channels (P<0.05). There was no statistical difference in the A value of EB absorbance between the bilateral non-channels of the abdomen and the back (P>0.05).ConclusionThere were differences in capillary distribution and permeability between the Conception Vessel, the Governor Vessel and the corresponding bilateral non-meridians
