Abstract
This chapter is a case study of the dissemination of railway engineering research in Latin America developed by a railway engineering research group. The leader of the group is a female researcher. The authors aim to inspire to other women researchers in Latin American and Caribbean (LAC) countries who are trying to develop research in IT areas, many times facing serious difficulties, incomprehension, and great challenges. This chapter is divided in set sections like introduction, background, development of railway engineering research. This third section is divided into subsections like timetable planning and trains control, characterization of Panama metro line 1, dwelling times, fuzzy logic, artificial intelligence, social-economics railway externalities, and environmental railway externalities. The fourth section presents the results of the relationship between research activity and teaching of railway engineering obtained in this case study. Finally, the authors present a brief vision about future and emerging regional trends about railway engineering projects.

Food Security and Self-Sufficiency as a Basis for National Security and Sovereignty: Evidence From Russia
To be food secure, a population, household or individual must have access to adequate food at all times. They should not risk losing access to food as a consequence of sudden shocks (e.g. an economic or climatic crisis) or cyclical events (e.g. seasonal food insecurity). The concept of stability can, therefore, refer to both the availability and access dimensions of food security.

Neural Networks and Equilibria, Synchronization, and Time Lags
Qualitative property of the solution of a system with the significance of the limitation of the perturbations effect on the considered solution viewed as basic. Among all kinds of stability (bounded input/bounded output, Lagrange stability, Birkhoff stability, input-to-state stability) the stability in the sense of Lyapunov - with respect to the initial conditions, viewed as incorporating the effect of short-period perturbations - is the most widely used; it means that sufficiently small deviations in the initial condition (state) will result in arbitrarily small deviations in the current state at all following moments. Rigorously, the basic solution of (3) is called stable in the sense of Lyapunov if, for any arbitrarily small and any there exists some sufficiently small such that if , then for all . If in the above definition is independent of the initial moment the stability is called uniform; from the point of view of the practice, this is the more important stability notion of stability. It is also a necessary condition for uniform asymptotic stability (see above).
