To date, various optimization algorithms have been used to design non-intuitive photonic structures with unconventional optical performance. Good training datasets facilitate the optimization process, particularly when a...

En Bartleby y compañía Enrique Vila-Matas reúne un gran número de relatos breves y brevísimos de escritores que en cierto momento de su vida dejaron de escribir. La autonomía de estos "microrrelatos" es parecida a ...

En este trabajo se estudió experimentalmente la influencia sobre la estabilidad de espumas en aerosol de concentrados con aspecto nacarado y, en algunos casos, además con características líquida cristalinas. Tanto el...

Se propone un método particular para seleccionar, de los nombres ya existentes, el más apropiado para cada músculo, y un método general para escoger los nombres apropiados de las estructuras anatómicas. Estos nombre...

"Las rocas correspondientes al ciclo Precuyano, afloran en la sierra de la Cara Cura, sur de la provincia de Mendoza. Es una secuencia volcano-sedimentaria de 419 m de espesor, constituidos por rocas volcánicas y pirocl...

MolProbity is a structure-validation web service that provides broad-spectrum solidly based evaluation of model quality at both the global and local levels for both proteins and nucleic acids. It relies heavily on the po...

BACKGROUND: The Avogadro project has developed an advanced molecule editor and visualizer designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related are...

We describe here a general Amber force field (GAFF) for organic molecules. GAFF is designed to be compatible with existing Amber force fields for proteins and nucleic acids, and has parameters for most organic and pharma...

How behavior and institutions are affected by social relations is one of the classic questions of social theory. This paper concerns the extent to which economic action is embedded in structures of social relations, in m...

Abstract Proteins are essential to life, and understanding their structure can facilitate a mechanistic understanding of their function. Through an enormous experimental effort 1–4 , the structures of around 100,000 un...

Many formal organizational structures arise as reflections of rationalized institutional rules. The elaboration of such rules in modern states and societies accounts in part for the expansion and increased complexity of ...

We show that microstructures built from nonmagnetic conducting sheets exhibit an effective magnetic permeability /spl mu//sub eff/, which can be tuned to values not accessible in naturally occurring materials, including ...

The Cambridge Structural Database (CSD) contains a complete record of all published organic and metal-organic small-molecule crystal structures. The database has been in operation for over 50 years and continues to be th...

Background Metal-organic frameworks (MOFs) are made by linking inorganic and organic units by strong bonds (reticular synthesis). The flexibility with which the constituents’ geometry, size, and functionality can be va...
