“…These modes originate from X 5ac , W 4ac and W 2ac modes of zinc-blende structure, respectively. γ for the X 5ac -originated mode is similar in magnitude and sign to values reported for zinc-blende structures [55][56][57][58]. Frequency and mode Grüneisen parameters at the W point for zinc-blende materials are, unfortunately, not as well known as those at the X point.…”

We have performed an ab initio study of the volume dependence of elastic and lattice dynamical properties of chalcopyrite semiconductor CuAlSe2. The calculations have been carried out within the local density functional approximation using norm-conserving pseudopotentials and a plane-wave basis. Born effective charge tensors, dielectric permittivity tensors, the phonon frequencies at the Brillouin zone centre and their Grüneisen parameters are calculated using density functional perturbation theory. We compare the Grüneisen parameters of the calculated quantities with those of zinc-blende type materials and find similar trends. Calculated elastic stiffness constants show pseudocubic behaviour.

“…Four Bragg peaks were measured: (18, 29), (20,32), (26, 41), and (52, 84). For each diffraction pattern, the position, the intensity, and the width at half-maximum (FWHM) of each Bragg peak were determined using the program edx [13].…”

We present results from in situ x-ray diffraction studies of hydrogenated icosahedral Ti-Zr-Ni quasicrystals carried out under high pressure. The icosahedral Ti53Zr27Ni20 phase and hydrogenated icosahedral Ti45Zr38Ni17 samples that contain 0.32 and 1.45 hydrogen atoms for each metal atom were studied. The icosahedral quasicrystal structure is retained up to the highest pressures investigated. The six-dimensional lattice parameter was obtained as a function of pressure for the different samples. The zero-pressure bulk modulus and its pressure derivative were determined by fitting a Murnaghan-type equation of state to the relative volume change V/V0. The zero-pressure bulk modulus is respectively obtained as B0 = 130±10, 105±10, and 110±20 GPa for H/M equal to 0, 0.32, and 1.45 using a constant value for the first derivative B'0: 5.5±1. It seems, therefore, that the icosahedral Ti-Zr-Ni phase may be more compressible after hydrogenation, but there is no clear difference for different H/M contents. These results are tentatively related to the local structure of these materials.

“…Una de esas maneras se refiere al carácter semántico del sujeto. Para el tseltal, por ejemplo, Polian (2013) explica que en las predicaciones existenciales el carácter semántico del sujeto es indefinido mientras que en las construcciones locativas es definido. Este mismo carácter semántico del sujeto se observa en las construcciones existenciales y locativas en las lenguas mayas acá exploradas.…”

Este artículo presenta dos propuestas de lectura para el glifo T667. La primera lectura sugerida es AY, con un valor semántico de predicado existencial, y la segunda es LAY, con un valor semántico de deíctico proximal. Estas propuestas de lectura se sustentan tanto en los patrones de complementación fonética como en el análisis sintáctico y semántico de las cláusulas representadas en los textos jeroglíficos donde T667 aparece en el Códice de Dresde (pp. 65b-69b, 30c-31c y 29c-30c). Para el primer caso, los patrones de complementación parecen estar deletreando la palabra ayan, un existencial con el cual se forman construcciones locativas. En el segundo caso, los patrones de complementación sugieren que se deletrea la palabra alay, un pronombre demostrativo que funciona como el núcleo de una predicación.
