To study the effects of chilling on dormancy breaking and the increased germination characteristics of Nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. Factor A was the chilling treatment in three levels (control, one-month and two-month ...

Ultra-light dark matter (ULDM) is a class of models (DM) where DM composed by bosons with masses ranging from $10^{-24}\, \mathrm{eV} < m \mathrm{eV}$. These have been receiving lot attention in the past few years given their interesting property forming Bose-Einstein condensate (BEC) or superfluid on galactic scales. BEC and superfluidity are one most striking quantum mechanical phenomena mani...

A sinusoidal grating can be viewed as a series of light and dark bars. Here we measure the contrast discrimination thresholds for light and dark bars individually, and find that the contrast discrimination thresholds for the whole sinusoid can be explained as ideal summation of the light and dark bar thresholds. We propose a model for light bar, dark bar, and sinusoidal contrast discrimination ...
