Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

Advanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

“El carácter total del mundo” Esbozo de una ontología del caos en Nietzsche

Ideas y Valores, 2017
Largamente desatendida o malinterpretada, la noción de caos en la filosofía de Nietzsche es una pieza constitutiva de la particular concepción del ser que este autor habría dejado apenas esbozada.

Irreversibilidad, caos y tiempo [PDF]

, 2013
Hay muchas paradojas que involucran el movimiento, la divisibilidad, y el infinito, como las paradojas de Zenón. Sin duda, estas paradojas han sido un gran estímulo para el pensamiento.

Fock representations of the superalgebra sl(n+1|m), its quantum analogue U_q[sl(n+1|m)] and related quantum statistics

, 2000
Fock space representations of the Lie superalgebra $sl(n+1|m)$ and of its quantum analogue $U_q[sl(n+1|m)]$ are written down. The results are based on a description of these superalgebras via creation and annihilation operators.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.
