Identificación en Lazo Cerrado de una Clase de Sistemas con Retardo Incierto en la Entrada
(2024)"En este trabajo de tesis se propone un esquema de control diseñado para una clase de sistemas lineales con retardo pequeño e incierto en la entrada. En particular, se combina un algoritmo de identificacion de retardo con ... -
Central Limit Theorem for a Class of Contractive Random Dynamical Systems and Critical Behavior in Connected Dynamical Systems
(2024)"In this thesis we use the spectral method to prove a Central Limit Theorem (CLT) for a class of contractive random dynamical systems. In this method, we start from the existence of a complex normed space in which the ... -
Anammox with alternative electron acceptors: perspectives for nitrogen removal from wastewaters
(Springer Nature, 2023)In the context of the anaerobic ammonium oxidation process (anammox), great scientific advances have been made over the past two decades, making anammox a consolidated technology widely used worldwide for nitrogen removal ... -
Dynamics of short-term ecosystem carbon fluxes induced by precipitation events in a semiarid grassland
(European Geosciences Union, 2023)Infrequent and small precipitation (PPT) events characterize PPT patterns in semiarid grasslands; however, plants and soil microorganisms are adapted to use the unpredictable small pulses of water. Several studies have ... -
Diversity and neocolonialism in Big Data research: Avoiding extractivism while struggling with paternalism
(SAGE, 2023)The extractive logic of Big Data-driven technology and knowledge production has raised serious concerns. While most criticism initially focused on the impacts on Western societies, attention is now increasingly turning to ... -
Simultaneous nitrification and autotrophic denitrification in fluidized bed reactors using pyrite and elemental sulfur as electron donors
(Elsevier, 2023)In this study, simultaneous nitrification and autotrophic denitrification (SNAD) with either elemental sulfur or pyrite were investigated in fluidized bed reactors in mesophilic conditions. The reactor performance was ... -
Extension of LoRa Coverage and Integration of an Unsupervised Anomaly Detection Algorithm in an IoT Water Quality Monitoring System
(MDPI, 2023)High cost, long-range communication, and anomaly detection issues are associated with IoT systems in water quality monitoring. Therefore, this work proposes a prototype for a water quality monitoring system (IoT-WQMS) based ... -
Modeling the Groundwater Dynamics of the Celaya Valley Aquifer
(MDPI, 2023)We propose a hydrodynamic simulation model to understand the piezometric operation of the Celaya Valley aquifer. The aquifer is located at the east of Guanajuato State in México. Our proposed model reproduces, under ... -
Effect of thermal and ultrasonic pretreatment on lactic acid fermentation of food waste
(SAGE, 2023)Food waste (FW) generation has become one of the largest environmental concerns for human society. Thanks to its chemical features and its high biodegradability, FW can be used as starting platform to produce biocommodities. ... -
An Observation of a Very High Swelling of Bromovirus Members at Specific Ionic Strengths and pH
(MDPI, 2023)Cowpea chlorotic mottle virus (CCMV) and brome mosaic virus (BMV) are naked plant viruses with similar characteristics; both form a T = 3 icosahedral protein capsid and are members of the bromoviridae family. It is well ... -
Multiplex assay for the simultaneous detection of antibodies against small ruminant lentivirus, Mycobacterium avium subsp. paratuberculosis, and Brucella melitensis in goats
(Veterinary World, 2023)Background and Aim: Brucellosis, paratuberculosis (PTb), and infections caused by small ruminant lentivirus (SRLV), formerly known as caprine arthritis encephalitis virus (CAEV), adversely affect goat production systems. ... -
Neo-functionalization in Saccharomyces cerevisiae: a novel Nrg1-Rtg3 chimeric transcriptional modulator is essential to maintain mitochondrial DNA integrity
(The Royal Society, 2023)In Saccharomyces cerevisiae, the transcriptional repressor Nrg1 (Negative Regulator of Glucose-repressed genes) and the ?-Zip transcription factor Rtg3 (ReTroGrade regulation) mediate glucose repression and signalling from ... -
Cell-type dependent regulation of pluripotency and chromatin remodeling genes by hydralazine
