A search is presented for direct pair production of the stop, the supersymmetric partner of the top quark, in a decay through an Formula Presented-parity violating coupling to a charged lepton and a Formula Presented-quark. The dataset corresponds to an integrated luminosity of Formula Presented of proton-proton collisions at a center-of-mass energy of Formula Presented collected between 2015 and

This study presents an example of when the government introduced a regulation that did not coincide research, professional ethics, responsibility or commitments, and led to a conflict between professionals and rulers.In the Swedish statutes regulating opioid maintenance treatment (OMT), a unique definition of the term opiate-dependency, the opiate rule, was introduced in 2010—restricting the targe
