New Algorithm Based on Sign Decomposition to Verify the Robust Stability Property for a Class of Linear Time-Delay Systems por Díaz Rodríguez, Iván D., Romero, Gerardo, Elizondo, Cesar

“…The analysis is made by replacing the time-delay part with an auxiliary equation and then using the sign definite decomposition to deal with the polynomic parametric uncertainty. Also, it is shown that it is possible to verify the robust stability property by first obtaining the Hurwitz matrix from the characteristic equation for this class of systems and then checking the leading principal minors positivity using the sign definite decomposition. …”

The dawn of the liquid biopsy in the fight against cancer por Domínguez Vigil, Irma Guadalupe, Moreno Martínez, Ana K., Wang, Julia Y., Roehrl, Michael H. A., Barrera Saldaña, Hugo Alberto

“…ABSTRACT Cancer is a molecular disease associated with alterations in the genome, which, thanks to the highly improved sensitivity of mutation detection techniques, can be identified in cell-free DNA (cfDNA) circulating in blood, a method also called liquid biopsy. This is a non-invasive alternative to surgical biopsy and has the potential of revealing the molecular signature of tumors to aid in the individualization of treatments. …”
