Value at Risk (VaR) in uncertainty: Analysis with parametric method and Black & Scholes simulations (Valor en Riesgo (VaR) en incertidumbre: Análisis con el método paramétrico y... by Banda Ortiz, Humberto, Pérez Sosa, Felipe, Gómez Hernández, Denise

“…For this reason, the aim of this work is to test the VaR accuracy when is employed in contexts of volatility, for which we compare the VaR outcomes in scenarios of both stability and uncertainty, using the parametric method and a historical simulation based on data generated with the Black & Scholes model. VaR main objective is the prediction of the highest expected loss for any given portfolio, but even when it is considered a useful tool for risk management under conditions of markets stability, we found that it is substantially inaccurate in contexts of crisis or high uncertainty. …”

Acondicionamiento de becerros previo a la recría bajo pastoreo en trópico seco: efectos sobre el peso corporal y la condición sanitaria by Guarneros Altamirano, Rafael, Gutiérrez Ornelas, Erasmo, Bernal Barragán, Hugo, Avalos Ramírez, Ramiro, Castillo Gallegos, Epigmenio, Olivares Sáenz, Emilio

“…In four periods of 28 d each, body weight and body condition score of the animals, blood urea nitrogen (BUN) and glucose (SG) in serum, as well as disease frequency in grazing calves were evaluated. Data of BW, cumulative body weight gain (BWG) BUN, and SG were analyzed with ANOVA in a 2 treatments x 2 sex factorial arrangement; morbility was analyzed by Ji square. …”

Plant characterization of genetically modified maize hybrids MON-89Ø34-3 × MON-88Ø17-3, MON-89Ø34-3 × MON-ØØ6Ø3-6, and MON-ØØ6Ø3-6: alternatives for maize production in Mexico... by Heredia Díaz, Oscar, Aldaba Meza, José Luis, Baltazar, Baltazar M., Bojórquez Bojórquez, Germán, Castro Espinoza, Luciano, Corrales Madrid, José Luis, De la Fuente Martínez, Juan Manuel, Durán Pompa, Héctor Abel, Alonso Escobedo, José, Espinoza Banda, Armando, Garzón Tiznado, José Antonio, González García, Juvencio, Guzmán Rodríguez, José Luis, Madueño Martínez, Jesús Ignacio, Martínez Carrillo, José Luis, Meng, Chen, Quiñones Pando, Francisco Javier, Rosales Robles, Enrique, Ruiz Hernández, Ignacio, Treviño Ramírez, José Elías, Uribe Montes, Hugo Raúl, Zavala García, Francisco

“…Two sets of studies, Experimental Phase and Pilot Phase, were conducted across five ecological regions (ecoregions) in Mexico during 2009–2013, and data were subject to meta-analysis. Results from the Experimental Phase studies, which were used for ERA, indicated that the three GM hybrids were not different from conventional maize for early stand count, days-tosilking, days-to-anthesis, root lodging, stalk lodging, or final stand count. …”

Actividad antibiofilm de un gel de nanopartículas lipofílicas de bismuto, contra el biofilm de Staphyloccoccus aureus sobre hueso. by Espinosa Villarreal, Erika Cecilia

“…Finally at 100μM of BisBAL NPs the hydrogel did not show toxicity on human gingival fibroblast, getting 85% of cell viability after 24h of treatment. All together these data show that a hydrogel loaded with BisBAL NPs is a safe and low cost alternative to fight infections caused by MRSA.…”
