Desafios jurídicos e econômicos da moeda digital
Mises, 2023 A moeda é um bem de conveniência muito antigo. No entanto, ao longo da história, conveniência e segurança tomaram lados opostos de um dilema, cuja superação ocorreu apenas nos últimos dois séculos com a moeda fiduciária.

Mechanical Engineering, 2001 This article describes application of finite element analysis (FEA) in snap tool, developed by Snap-on Inc. in Kenosha, Wisconsin. FEA has been finding its way down the engineering chain with the help of easy-to-use software. FEA is the use of a complex system of points—called nodes—that form a grid, or mesh, across a model.

Nano‐Architected Metallic Metamaterial With Enhanced Fatigue Resistance via Dislocation Starvation
Advanced Materials, EarlyView.Nanoscale Ni single crystals exhibit remarkable fatigue resistance over an order of magnitude higher than that of bulk single crystals through dislocation starvation. By translating this mechanism into geometric nano‐architecture, nano‐architected Ni single‐crystal metamaterials achieve about twice the fatigue resistance of the bulk, despite their ...

Advanced Materials, EarlyView.We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Mechanical Engineering, 2012 This article explores the application of finite element analysis (FEA) in studying the evolution of animals, including dinosaurs. Scientists have applied the method to determine how dinosaurs originally looked and functioned, and how they and other animals changed and evolved through the years.
