"Lentus in umbra", por Tomás Rueda Vargas

A Conversation with Tomás Palacios

I n recent years, the family of two-dimensional materials has expanded from the purely carbon graphene to include almost 1,000 materials that existor are predicted to existin an atomically thin form. These 2-D materials are flexible and transparent, and their unusual properties make researchers eager to apply them in electronic devices. Electrical engineer Tomás Palacios of the Massachusetts ...

The Umbra Simulation Framework

Umbra is a new Sandia-developed modeling and simulation framework. The Umbra framework allows users to quickly build models and simulations for intelligent system development, analysis, experimentation, and control and supports tradeoff analyses of complex robotic systems, device, and component concepts. Umbra links together heterogeneous collections of modeling tools. The models in Umbra inclu...

Wild-type oenological strains of Saccharomyces cerevisiae are usually aneuploid and heterozygotes; thus, when they are used as starters in must fermentation the resulting wine characteristics may vary from year to year. Treatment of a wild-type S. cerevisiae oenological strain with benomyl (methyl-l-butylcarbamoyl-2-benzimidazole carbamate), an antifungal agent shown to cause chromosome loss in...

Light Source Object Layered Penumbra Umbra

Shadows serve as e ective cues for a user to recognize spatial relations among objects in 3D space. However simple shadows typically used in 3D interfaces are often insu cient for the purpose, and rendering of shadows with real penumbra are not only too costly for interactive interfaces, but also do not enhance their capabilities as spatial cues. Our proposal, layered penumbra is a new interact...
