No linealidad, complejidad y sistemas sociales

Revista de Antropología y Sociología Virajes, 2008
El artículo inicia presentando un panorama acerca de los intentos de elaborar modelos de la realidad, que van desde la visión lineal clásica de las ciencias naturales hasta concepciones que aceptan la existencia del  caos y de la impredecibilidad. Luego

Estructura de la velocidad durante un episodio caótico

Revista de Investigación de Física, 2015
Se ha realizado una investigación sobre la estructura de la velocidad en el oscilador no-lineal forzado y amortiguado durante un episodio caótico. Se ha encontrado que los valores extremos de la velocidad muestran una cascada de bifurcación a medida que ...

Synergistic Remodeling of Tumor Immune Microenvironment via a DNA Nanodevice Integrating STING Activation and Lysosome‐Targeted PD‐L1 Degradation

Advanced Science, EarlyView.
A rational design DNA nanoplatform not only achieves efficient PD‐L1 degradation but also triggers robust STING signaling. The nanodevice effectively reprograms “cold” tumors, leading to potent inhibition of tumor growth and metastasis in vivo. ABSTRACT The cGAS‐STING pathway is a cornerstone of innate antitumor immunity; however, its therapeutic ...

Machine Learning Accelerated Non‐Adiabatic Molecular Dynamics Elucidates Local Polarization Effects on Non‐radiative Recombination in Halide Perovskites

Advanced Science, EarlyView.
This work proposes and constructs the Hefei‐NAMD‐S framework based on machine learning stacked models to investigate the relationship between local polarization and non‐radiative recombination. The results indicate that, compared with A‐site local polarization, B‐site local polarization shows a more evident association with the non‐radiative ...

Ultrafast Hot‐Carrier Cooling in CsPbBr3 Supercrystals via Long‐Range Electronic Coupling

Advanced Science, EarlyView.
CsPbBr3 supercrystal self‐assembly, which induces long‐range electronic coupling, enables spatial carrier delocalization that accelerates carrier‐LO phonon scattering and weakens the Auger heating. These effects enable ultrafast, excitation‐intensity‐independent hot‐carrier cooling, offering a trade‐off‐free strategy for high‐performance perovskite ...

Determination of the Rate of CO2 Dissociation on the Surface of CaO-SiO2, CaO-Al2O3, CaO-SiO2-CaF2 and CaO-SiO2-FexO Melts.

ISIJ International, 1996
The rate constant of CO2 dissociation on the surfaes of CaO-SiO2, CaO-Al2O3, CaO-SiO2-CaF2 and CaO-SiO2-FexO slags was measured by means of a 13CO2-CO isotope exchange technique as functions of slag basicity, iron content, temprature and imposed equilibrium CO2/CO ratio.

Hair Follicle Seedling Cryomicroneedles from Hierarchical Microfluidic Organoid on a Chip

Advanced Science, EarlyView.
In this paper, a hierarchical microfluidic chip is developed to produce uniform hair follicle organoids (HFOs) in cryomicroneedles. Cryopreservation agents encapsulate HFOs, preserving viability and hair growth potential. The cryomicroneedles enable simple intradermal transplantation with good skin penetration.

A final act of love: The decision-making experience of Malaysian owners electing companion animal euthanasia

Human-Animal Interactions
Companion animal owners (CAOs) may resonate with the struggle that life rests on their hands to say yes or no when considering companion animal euthanasia (CAE). This can lead to guilt, doubt, and self-blame, increasing complicated grief risks.

Colossal Photovoltaic Current in Ferroelectric Oxide by Constructing Defect Band

Advanced Science, EarlyView.
Colossal photovoltaic current density of 34.36 mA/cm2 under 375 nm illumination has been achieved in the Pb‐deficient PbTiO3 film. The ultraviolet photoresponsivity surpasses that of all reported ferroelectric materials. This enhancement is attributed to the junction effect between the Pb‐deficient and non‐defective layers.
