Emiliano Zapata ou la photographie au service de la construction d’une icône by Marion Gautreau

“…Through the analysis of the publication of Zapata’s photographs in the Mexican illustrated press and the study of some specific portraits, we try to decode the double iconic process: the historical figure and the one in the portraits.…”

The Imprint of the War in Ford Madox Ford’s Critical Writings by Isabelle BRASME

“…Ford Madox Ford said of the year 1914 that it “seem[ed] to be cut in half” by the First World War (“Literary Portraits – LXIX”, 15). This phrase, one may argue, also largely applies to Ford’s personal timeline. …”

Explicit Wave Solutions and Qualitative Analysis of the (1 + 2)-Dimensional Nonlinear Schrödinger Equation with Dual-Power Law Nonlinearity by Qing Meng, Bin He, Zhenyang Li

“…The (1 + 2)-dimensional nonlinear Schrödinger equation with dual-power law nonlinearity is studied using the factorization technique, bifurcation theory of dynamical system, and phase portraits analysis. From a dynamic point of view, the existence of smooth solitary wave, and kink and antikink waves is proved and all possible explicit parametric representations of these waves are presented.…”
