“Last-chance” sales: what makes them credible? por Muñoz García, Félix, González Lozano, Heriberto

“…Then, the set of separating and pooling equilibria is characterized, so that the above usual advertising techniques can be better understood as equilibria of this model for certain parameter values. In particular, this paper shows that, when the firm which continues in the business knows that few of their current customers will come back in future periods, the set of separating equilibria shrinks. …”

Relative humidity measurement based on a tapered, PVA-coated fiber optics multimode interference sensor por Quiñones Flores, Abraham A., Guzman Sepulveda, Jose R., Castillo Guzman, Arturo A.

“…The native MMI sensor showed a sensitivity of 5.6nm/RH%, in the range from 87 RH% to 93 RH%, while the tapered one exhibited an increased sensitivity of 6.6nm/RH%, in the range from 91.5 RH% to 94 RH%. The sensitivity values obtained with these MMI sensors are at least twice as large as the most sensitive fiber optics humidity sensor reported in the literature in a similar RH range.…”
