Selfish and Altruistic Bacterial Populations Maximize Fitness Under Stress by Local Segregation [PDF]

open access: yes, 2008
Landscapes in ecology have a profound influence on the adaption and evolution of competing populations for resources. We are interested in how altruistic populations survive in the presence of selfish individuals in a non-stirred, closed and complex ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Blanchot y la lógica de la desapropiación

open access: yesValenciana, 2020
Frente a Hegel y la dialéctica, algunos autores como Maurice Blanchot contraponen la amistad como relación humana esencial y la experiencia estética como paradigma de la acción, relegando el trabajo, que es servil siempre, como modelo decaído de la misma.

What Do Large Language Models Know About Materials?

open access: yesAdvanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Liberty for Security [PDF]

open access: yes, 2001
On 11 September 2001, we collectively endured the worst tragedy to touch American soil since the Civil War. In the wake of this horrible event, a national hysteria erupted. People are anxious to restore the lost security; but at what cost? Many Americans

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

open access: yesAdvanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

Gettysburg\u27s Tragedy in Virginia [PDF]

open access: yes, 2014
Jacob and John Kitzmiller were brothers-in-arms, fighting through the thickets of Virginia with the 138th Pennsylvania. And spring of 1864 was one hell of a slog. The two boys were the youngest members of their family.
