Strong Bounds on Sum of Neutrino Masses in a 12 Parameter Extended Scenario with Non-Phantom Dynamical Dark Energy ()
We obtained constraints on a 12 parameter extended cosmological scenario
including non-phantom dynamical dark energy (NPDDE) with CPL parametrization.
We also include the six CDM parameters, number of relativistic
neutrino species () and sum over active neutrino masses
(), tensor-to-scalar ratio (), and running of the
spectral index (). We use CMB Data from Planck 2015; BAO Measurements
from SDSS BOSS DR12, MGS, and 6dFS; SNe Ia Luminosity Distance measurements
from the Pantheon Sample; CMB B-mode polarization data from BICEP2/Keck
collaboration (BK14); Planck lensing data; and a prior on Hubble constant
( km/sec/Mpc) from local measurements (HST). We have found strong
bounds on the sum of the active neutrino masses. For instance, a strong bound
of 0.123 eV (95\% C.L.) comes from Planck+BK14+BAO. Although
we are in such an extended parameter space, this bound is stronger than a bound
of 0.158 eV (95\% C.L.) obtained in with Planck+BAO. Varying instead of
however leads to weaker bounds on . Inclusion of the HST leads to
the standard value of being discarded at more than
68\% C.L., which increases to 95\% C.L. when we vary
instead of , implying a small preference for dark radiation, driven
by the tension.Comment: 23 pages, 10 figures, matches the published versio

Breakage of the needle and missing while repairing the uterine wound during cesarean section is an uncommon event. Subsequently it was removed under fluoroscopic guidance on the 7th postoperative da
An Atypical Case of Pelvic Leiomyomatosis Peritonealis Disseminata
An exceptional case of Leiomyomatosis peritonealis disseminata which occurred in a perimenopausal woman was mistaken for ovarian malignancy at laparotomy as it had extensive involvement of the pelvic peritoneum without a trace of leiomyoma in uterus and cervix
