Background: Heat and moisture exchangers (HMEs) are commonly used in chronically tracheostomized spontaneously breathing patients to condition inhaled air maintaining lower airway functions and minimizing viscosity of secretions. Supplemental oxygen flow can be added to most HMEs designed for spontaneously breathing tracheostomized patients....

The recently measured B → τ ν branching ratio allows to test the Standard Model by probing virtual effects of new heavy particles, such as a charged Higgs boson. The accuracy of the test is currently limited by the experimental error on BR(B → τν) and by the uncertainty on the parameters fB and |Vub|. The redundancy of the Unitarity Triangle...
