Silicon-based photodetectors operating in the near-infrared (NIR) wavelength range (λ = 700–1,100 nm) are essential for applications such as light detection and ranging, facial recognition, and eye-tracking. However...

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...

Los campos geotérmicos localizados en orogenos vinculados a zonas de subducción, están estrechamente relacionados con áreas caracterizadas por la presencia de actividad magmática y tectónica joven, tanto en configu...

En el presente trabajo se analizan mediciones de dos y tres componentes instantáneas de la velocidad del viento, adquiridos simultáneamente a dos y cuatro alturas, en el seno del bosque y por arriba del mismo, en una t...

"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...

The Guañacos fold and thrust belt, located between 37° and 38° S in the eastern foothills of the Main Andes is characterized at its eastern border by a series of NE, NW and N- neotectonic faults associated with the An...

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...
