A description of the epidemiological dynamics of Chagas disease via mathematical modeling
Lozada-Yavina, Rafael; Marchant, Carolina; Cancino-Faure, Beatriz ; Hernández-Rodríguez, Erix W.; Córdova-Lepe, Fernando (2023)Chagas disease is caused by the protozoan Trypanosoma cruzi, which parasitizes many mammals, including humans. Its vectors are blood-feeding hematophagous triatomine insects of different species, which vary according to ...

A generalized local function in ideal topological spaces
Tormet, José; Lozada-Yavina, Rafael; Salas-Brown, Margot (2022)In this paper we introduce a generalization of the notion of local function using operators associated to the topology. Similarly, a notion of compatibility of the ideal with the topology is introduced utilizing this new ...

Characterization of the 1-(5-(4,5-Dimethyl-1,3,2-dioxoborolan-2-yl)thiophen-2-yl)ethanone using NMR 13C, 1H and 11B through the density functional
Guevara, Ulises J.; Núñez R., Jesús; Lozada-Yavina, Rafael; Tiutiunnyk, Anton; Pérez, Laura; Díaz, Pablo; Urdaneta, Neudo; Laroze, D. (2023)The use of computational methods that allow us to perform characterization on new compounds is not a novelty; nevertheless, the degree of complexity of the structures makes their study more challenging since new techniques ...

Filarial nematodes in domestic dogs and mosquitoes (Diptera: Culicidae) from semi-rural areas in Central Chile
Cancino-Faure, Beatriz ; González, Christian R.; Piñeiro González, Alejandro; Pinochet, Soledad; Bustos, Sofía; Morchón García, Rodrigo; Piñeiro Cazaux, Alejandro; Quezada Aguilar, Ivonne; Salas Espinoza, Merayot; Acevedo Salgado, Rodrigo; Barra Díaz, Carmen; Segovia C., Christian; Lozada-Yavina, Rafael; Álvarez Rojas, Cristian A (2023)Climate change, competent vectors, and reservoir animals are the main factors for developing vector-borne zoonotic diseases. These diseases encompass a significant and widespread category of pathogens (e.g., viruses, ...

Northern and central Chile still free of emerging flaviviruses in mosquitoes (Diptera: Culicidae)
Cancino-Faure, Beatriz ; González, Christian R.; Piñeiro González, Alejandro; Salazar-Viedma, M.; Pastenes, Luis; Valdés, Elizabeth; Bustos, Camila; Lozada-Yavina, Rafael; Canals, Mauricio (2023)Geographic isolation and strict control limits in border areas have kept Chile free from various pathogens, including Flavivirus. However, the scenario is changing mainly due to climate change, the reintroduction of more ...
