The carotid body oxygen sensor

Gao Chen, Lin · Moreno Domínguez, Alejandro · Ortega Sáenz, Patricia + 1 author

2025Publisher: ElsevierRepository: idUS — Universidad de Sevilla

Carotid body (CB) chemoreceptor glomus cells sense hypoxia through the inhibition of plasmalemmal K+ channels, which leads to the opening of Ca2+ channels, Ca2+ influx, and neurotransmitter release. The mechanism of O2 sensing and the regulation of membrane ion channels by O2…

Digital teaching competence regarding foreign languages and learning modes at Official Language Schools in Andalusia (Spain)

Rubio Gragera, María · Palacios Rodríguez, Antonio de Padua · Cabero Almenara, Julio + 1 author

2025Publisher: MDPIRepository: idUS — Universidad de Sevilla

Despite the limited academic focus on the context of Official Language Schools (OLSs), these institutions play a crucial role in the formal education system, which are exclusively dedicated to foreign language teaching across various modalities in Andalu- sia, where ten…

Apico-basal intercalations enable the integrity of curved epithelia

Anbari, Samira · Gómez Gálvez, Pedro · Vicente Munuera, Pablo + 2 authors

2025Publisher: ElsevierRepository: idUS — Universidad de Sevilla

Non-invasive force inference based on imaging data has significantly advanced our understanding of the mechanical cues driving morphogenesis. In 2D studies of confluent tissues, these methods allow for the computation of forces acting on cells by analyzing their geometrical…

Asymptotic behavior of stochastic delay Navier-Stokes equations on unbounded domains

Zhang, Qiangheng · Caraballo Garrido, Tomás · Yang, Shuang

2025Publisher: International PressRepository: idUS — Universidad de Sevilla

In this paper, the random dynamics of non-autonomous stochastic Navier-Stokes equations with variable delays on unbounded Poincaré domains is analysed. First, we establish the existence, uniqueness and backward compactness of pullback random attractors. Second, we study the…

A solution to SAT with virus machines with pre-computed resources

Orellana Martín, David · Zandron, Claudio · Leporati, Alberto

2025Publisher: Springer NatureRepository: idUS — Universidad de Sevilla

In Natural Computing, different real-life processes can appear as the inspiration for a new model of computation. Virus machines use the spread and replication of biological viruses as an inspiration for a model of computation with three well differentiated graphs: the hosts…

Porosity efect on the thermal conductivity of sintered powder materials

Montes Martos, Juan Manuel · Gómez Cuevas, Francisco de Paula · Cintas Físico, Jesús + 1 author

2025Publisher: SpringerRepository: idUS — Universidad de Sevilla

In this work, the effective thermal conductivity of sintered powder materials is studied. The extensive literature related to the proposed models about this property in all kind of porous materials is reviewed, and a new equation is proposed as a function of the fully dense…
