Search for a heavy neutral particle decaying into an electron and a muon using 1 fb−1 of ATLAS data

open access: yesEuropean Physical Journal C: Particles and Fields, 2011
A search is presented for a high mass neutral particle that decays directly to the e ± μ ∓ final state. The data sample was recorded by the ATLAS detector in $\sqrt{s}=7\mbox{~TeV}$ pp collisions at the LHC from March to June 2011 and corresponds to an ...

Effect of circulating prolactin, lactation days, and seasonal variations on first artificial insemination pregnancy rates using the PG7G protocol in dairy cows [PDF]

open access: yesVeterinary World
Background and Aim: Dairy farm profitability is linked to milk yield and reproductive efficiency. High prolactin levels during lactation can negatively impact fertility. Timed AI protocols like PG7G are used to improve pregnancy rates.
