Gauge symmetries remove unphysical states and guarantee that field theories are free from the pathologies associated with these states. In this work we find a set of general conditions removal in describing interacting vector fields. These obtained through extension mechanism for emergence gauge proposed previous article [C. Barcel\'o J. High Energy Phys. 10 (2016) 084] order to account non-Abe...

Elevated shock impedance might indicate structural compromise to implantable cardioverter-defibrillator (ICD) leads. Defibrillation or can be measured in two ways: through high output therapy termed true (TSI); a calculated value using low voltage sub-threshold measurement (LVSM). We have identified 3 cases of gradual LVSM rises (>130 ohm) patients with Endotak Reliance ICD leads at our institu...
