MEASURING TISSUE DEFORMATION FROM ULTRASOUND IMAGE SEQUENCES

open access: yes, 2020
Elastic Modulus Imaging (EMI) is an emerging and exciting suite of medical imaging techniques. The goal of biomechanical imaging is to map the mechanical properties, for example Young's Modulus, of soft tissues.

Evidence for tWZ production in proton-proton collisions at s=13 TeV in multilepton final states

open access: yesPhysics Letters B
The first evidence for the standard model production of a top quark in association with a W boson and a Z boson is reported. The measurement is performed in multilepton final states, where the Z boson is reconstructed via its decays to electron or muon ...
