Caracterización de lugares geométricos y la complejidad de la dimensión fractal

open access: yes, 2023
To understand and explain the various natural phenomena in the world, it is no longer enough to use whole dimensions. This work answers the question: Is there complexity to obtain a fractal dimension associated with different curves and sets?

Comparative evaluation of vertical dimension at rest before extraction, after extraction and after rehabilitation with complete denture – A Cephalometric study

open access: yesJournal of Oral Biology and Craniofacial Research, 2013
Introduction: The determination of physiologic rest position of the mandible to the maxillae is of paramount importance in almost all fields of dentistry. The stability of vertical dimension at rest has been controversial if the rest position of mandible

The Duration of History in Bergson

open access: yesBergsoniana, 2021
Although he developed one of the most important modern theories of time, Bergson has often been criticised for not thinking history. Drawing on his writings from Creative Evolution to The Two Sources, I show that, on the contrary, he was trying to define

THE NATURAL-LEGAL DIMENSION OF A PERSON’S STATUS [PDF]

open access: yesЭлектронное приложение к Российскому юридическому журналу, 2019
The natural law theory of a person as a substance of his own is presented in the article. The author analyzes historical and contemporary theories and states that any human rights and freedoms can be derived only from such a fundamental level, that a ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Clasificación de células cancerígenas mediante dimensión fractal

open access: yes, 2022
“Para explicar los fenómenos geométricos de la naturaleza, la geometría euclidiana no puede dar una explicación acertada a todo, para ello la geometría fractal se encarga en gran medida de esto: da un entendimiento de la rigurosidad de la naturaleza, que

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Conexiones invariantes en espacios homogéneos de baja dimensión [PDF]

open access: yes, 2018
Entendemos por espacio homogéneo una variedad dotada de una acción transitiva de un grupo de Lie. Como ejemplos de espacios homogéneos tenemos los espacios euclídeos, afines, proyectivos e hiperbólicos.

Identification of natural fractures using resistive image logs, fractal dimension and support vector machines

open access: yesIngeniería e Investigación, 2016
The purpose of this research is to apply a new approach to identify natural fractures in wells in a hydrocarbon reservoir using resistive image logs, fractal dimension and support vector machines (SVMs).

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
