Mindlin-Reissner Analytical Model with Curvature for Tunnel Ventilation Shafts Analysis por Alvarez Pérez, José, Peña, Fernando

“…Abstract: The formulation and analytic solution of a new mathematical model with constitutive curvature for analysis of tunnel ventilation shaft wall is proposed. Based on the Mindlin–Reissner theory for thick shells, this model also takes into account the shell constitutive curvature and considers an expression of the shear correction factor variable (αn) in terms of the thickness (h) and the radius of curvature (R). …”

Histopathological Analogies in Chronic Pulmonary Lesions between Cattle and Humans: Basis for an Alternative Animal Model por Ramírez Romero, Rafael, Nevárez Garza, Alicia Magdalena, Rodríguez Tovar, Luis Edgar., Wong González, Alfredo, Ledezma Torres, Rogelio Alejandro, Hernández Vidal, Gustavo

“…Herein, the aim was to review, under a medical perspective, the pathologic mechanisms operating in these chronic pneumonic lesions in calves. Based on the similarities of these changes to those reported in bronchiolitis obliterans/organising pneumonia (BO/OP) and chronic obstructive pulmonary disease (COPD) in human beings, calves are proposed as an alternative animal model.…”

“…This is the first report of Decamastus Hartman, 1963 in the Tropical Eastern Pacific, since two previous records were misidentified. Based on individuals from the continental shelf of the Gulf of California, Decamastus okuilin sp. n. is described, illustrated, and compared with the other species of the genus. …”

Interscapular-thoracic amputation: A giant Dermatofibrosarcoma Protuberans treatment por De Anda Coronado, Alberto, López Leonar, Nohemí C., Navarro Bahena, Eduardo, Muñoz Maldonado, Gerardo Enrique

“…Background: Dermatofibrosarcoma protuberans (DFSP), an uncommon sarcoma of the dermis, is a low-grade, spindle-cell tumor that usually grows slowly and has a high local recurrence rate, but rarely metastasizes to distant sites. The diagnosis is based on histopathology and the standard treatment is wide surgical excision with tumor-free margins. …”

Alternative Method to Estimate the Fourier Expansions and Its Rate of Change por Rodríguez Maldonado, Johnny, Posadas Castillo, Cornelio, Zambrano Serrano, Ernesto

“…This paper presents a methodology to obtain the Fourier coefficients (FCs) and the derivative Fourier coefficients (DFCs) from an input signal. Based on the Taylor series that approximates the input signal into a trigonometric signal model through the Kalman filter, consequently, the signal’s and successive derivatives’ coefficients are obtained with the state prediction and the state matrix inverse. …”
