New Algorithm Based on Sign Decomposition to Verify the Robust Stability Property for a Class of Linear Time-Delay Systems by 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. …”

Consumer behavior as an advantage. by Esquivel Aguilar, Lizbeth, Véliz Reyna, Carolina, Rodríguez Chapa, Martin Alejandro, Cortés Sánchez, Ruth Yamilet

“…Our goal is to get as much customers as we can, so it’s important to give them what they want with the service they expect, so it’s of great importance to have quality, the customers can trust in the company, the product they offer has quality, so they’ll want to purchase what the company has to offer; but isn’t just about the quality, it’s also about the price, the customers always want the less expensive item, so it’s important to make a balance of how much it cost to produce the product and how much the customer it’s willing to pay, to archive the most convenient cost. …”

The dawn of the liquid biopsy in the fight against cancer by 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. …”

Determination of the cytotoxic capacity of organotin compounds derivatives from salicylidene benzoylhidrazone by Berrones Reyes, Jessica Cecilia

“…Conclusions and contribution: In this research work, we reported four new tin compounds derivatives from bezoylhidrazones, which were characterized by spectroscopic and spectrometric techniques and X-ray diffraction In the same manner, cytotoxic ability of each compound was studied and reported and compared with metaled base drugs like cisplatin and carboplatin. Also, in some cases it was possible to use their luminescent ability to study their intracellular behavior.…”
