Unraveling the Dynamics of Oxytocin in Hypothalamic Neurons. [PDF]

Traffic
Oxytocin (OT) plays an important role in regulating social behavior, and dysregulation of the oxytocinergic system leads to social impairments, such as autism spectrum disorder. Central OT release is poorly understood. Using live‐cell imaging to track vesicle trajectories, combined with machine learning‐based classification, the analysis reveals ...

Simplifying Implications with Positive and Negative Attributes: A Logic-Based Approach

Mathematics, 2022
Concepts and implications are two facets of the knowledge contained within a binary relation between objects and attributes. Simplification logic (SL) has proved to be valuable for the study of attribute implications in a concept lattice, a topic of ...

Minimal Generators from Positive and Negative Attributes: Analysing the Knowledge Space of a Mathematics Course

International Journal of Computational Intelligence Systems, 2022
Formal concept analysis is a data analysis framework based on lattice theory. In this paper, we analyse the use, inside this framework, of positive and negative (mixed) attributes of a dataset, which has proved to represent more information on the use of

An Expository Lecture of María Jesús Chasco on Some Applications of Fubini’s Theorem

Axioms, 2021
The usefulness of Fubini’s theorem as a measurement instrument is clearly understood from its multiple applications in Analysis, Convex Geometry, Statistics or Number Theory. This article is an expository paper based on a master class given by the second

About a dubious proof of a correct result about closed Newton Cotes error formulas

Open Mathematics, 2023
In this study, we comment about a wrong proof, at least incomplete, of the closed Newton Cotes error formulas for integration in a closed interval [a,b].\left[a,b].

Non-monotonic dependence of avalanche durations on particle velocities in the discharge of a silo [PDF]

EPJ Web of Conferences, 2021
The distributions of avalanche times between successive clog events are analyzed in a silo discharged with a conveyor belt. In a previous work [Phys. Rev. Lett. 121, 138001 (2018)], we measured the distribution of avalanche sizes (in number of particles)
