Each year, more than 10 million people enter US jails, most returning home within a few weeks. Because jails concentrate people with infectious and chronic diseases, substance abuse, and mental health problems, and reentry policies often exacerbate these problems, the experiences of people leaving jail may contribute to health inequities in the low-income communities to which they return. Our s...

Reentry is the most common mechanism for arrhythmia in patients treated in the electrophysiology laboratory. Mapping and defining the exact circuit to then allow targeting an ideal site for ablation is challenging. However, as reentry usually involves a relatively large circuit often coupled with a discrete slow zone of conduction, we are able to use the classical techniques of entrainment mapp...

the interpolated retrograde P waves, the retrograde limb of a SAN reentry in the SAN junction probably would also have been blocked. Therefore, it’s highly unlikely the NPs occur as a result of SAN reentry with a failure to depolarize the left atrium. However, the NPs may represent right atrial depolarizations in left atrial P waves originating near the left atrial termination of BB (Fig 82) wh...

Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain  mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...

We have investigated the effects of electric field stimulation on membrane repolarization in rabbit papillary muscles and assessed the consequences of these effects for the dispersion of intracellular potentials and the production of a propagation wave front or unidirectional block in relatively refractory tissue. The stimuli studied had electric field strength of 0.25-14 V/cm, duration of 2 ms...
