Is dark energy evolving?
Remya Nair, Sanjay Jhingan
We look for evidence for the evolution in dark energy density by employing Principal Component Analysis (PCA). Distance redshift data from supernovae and baryon acoustic oscillatio…
Facile synthesis and step by step enhancement of blue photoluminescence from Ag-doped ZnS quantum dots
Sonal Sahai, Mushahid Husain, Virendra Shanker +2
Our results pertaining to the step by step enhancement of photoluminescence (PL) intensity from ZnS:Ag,Al quantum dots (QDs) are presented. Initially, these QDs were synthesized us…
A Novel Anticlustering Filtering Algorithm for the Prediction of Genes as a Drug Target
Khalid Raza, Akhilesh Mishra
The high-throughput data generated by microarray experiments provides complete set of genes being expressed in a given cell or in an organism under particular conditions. The analy…
Spontaneous symmetry breaking in cosmos: The hybrid symmetron as a dark energy switching device
K. Bamba, R. Gannouji, M. Kamijo +2
We consider symmetron model in a generalized background with a hope to make it compatible with dark energy. We observe a "no go" theorem at least in case of a conformal coupling. B…
Dynamics of Dark Matter in Baryon-Radiation Plasma: Perspectives using Meschersky equation
Himanshu kumar, Sharf Alam
With an aim to argue for the truly collisionless nature of cold dark matter between epochs of equality and recombination, we assume a model, wherein strongly coupled baryon-radiati…
Surface tension with Normal Curvature in Curved Space-Time
Himanshu kumar, Sharf Alam, Suhail Ahmad
With an aim to include the contribution of surface tension in the action of the boundary, we define the tangential pressure in terms of surface tension and Normal curvature in a mo…
