Gaussian and Cauchy Functions in the Filled Function Method – Why and What Next: On the Example of Optimizing Road Tolls por Flores Muñiz, José Guadalupe, Kalashnikov, Vyacheslav V., Kreinovich, Vladik, Kalashnykova, Nataliya I.

“…There exist many optimization algorithms, the problem is that these algorithms often end up in a local optimum. One of the promising methods to avoid the local optima is the filled function method, in which we, in effect, first optimize a smoothed version of the objective function, and then use the resulting optimum to look for the optimum of the original function. …”

Anticorrosive efficiency of the AISI 316 SS in sustainable ecological concrete manufactured with SCBA-SF exposed to magnesium sulphate por Baltazar García, Brenda Paola, Baltazar Zamora, Daniel Francisco, Landa Ruiz, Laura, Reyes, José, Lozano, David, Santos, Gabriel, Tochtli Méndez, Ce, Estupiñan López, Francisco Humberto, Gaona Tiburcio, Citlalli, Baltazar Zamora, Miguel Ángel

“…The values of ecorr indicate in the AISI 316 SS a 10% of corrosion risk and uncertainty at the end of monitoring, according to the norm ASTM C-876-15, in all the mixtures, but the values of icorr in the specimens manufactured with SEC indicate resistance to sulfate corrosion more than 10 times compared to conventional concrete and AISI 1018 steel.…”

An Update on Calciphylaxis por García Lozano, José Alberto, Ocampo Candiani, Jorge, Martínez Cabriales, Sylvia Aideé, Garza Rodríguez, Verónica

“…Calciphylaxis, also known as calcific uremic arteriolopathy and uremic small artery disease with medial wall calcification and intimal hyperplasia, is a multifactorial cutaneous vascular disease characterized by chronic, painful, non-healing wounds that occur frequently in patients with chronic kidney disease, predominantly in those with end-stage renal disease. The pathogenesis remains unclear, and the development of calciphylaxis lesions depends on medial calcification, intimal fibrosis of arterioles and thrombotic occlusion. …”

Efficacy of DA-7218, a new oxazolidinone prodrug, in the treatment of experimental actinomycetoma produced by nocardia brasiliensis por Espinoza González, Nelly Alejandra, Welsh Lozano, Oliverio, De Torres, Noemi Waksman, Cavazos Rocha, Norma Cecilia, Ocampo Candiani, Jorge, Said Fernández, Salvador, Lozano Garza, Gerardo, Choi, Sung Hak, Vera Cabrera, Lucio

“…We first determined the plasma concentration of the prodrug in BALB/c mice using several doses and then tested its activity in an in vivo experimental actinomycetoma murine model. At the end of treatment, there was a statistically significant difference between the three drug receiving groups (25, 12.5 and 5 mg/kg) and the control group (saline solution) (p=0.001), proving that DA-7218 is effective for the treatment of experimental murine actinomycetoma. …”
