Fabrication system, method and apparatus for microelectromechanical devices

A fabrication system and method of fabrication for producing microelectromechanical devices such as field-effect displays using thin-film technology. A spacer is carried at its proximal end on the surface of a substrate having field-effect emitters with the spacer being enabled for tilting movement from a nested position to a deployed position which is orthogonal to the plane of the substrate. An actuator is formed with one end connected with the substrate and another end connected with spacer. The actuator is made of a shape memory alloy material which contracts when heated through the material's phase-change transition temperature. Contraction of the actuator exerts a pulling force on the spacer which is tilted to the deployed position. A plurality of the spacers are distributed over the area of the display. A glass plate having a phosphor-coated surface is fitted over the distal ends of the deployed spacer

Statistics of leading digits leads to unification of quantum correlations

We show that the frequency distribution of the first significant digits of the numbers in the data sets generated from a large class of measures of quantum correlations, which are either entanglement measures, or belong to the information-theoretic paradigm, exhibit a universal behaviour. In particular, for Haar uniformly simulated arbitrary two-qubit states, we find that the first-digit distribution corresponding to a collection of chosen computable quantum correlation quantifiers tend to follow the first-digit law, known as the Benford's law, when the rank of the states increases. Considering a two-qubit state which is obtained from a system governed by paradigmatic spin Hamiltonians, namely, the XY model in a transverse field, and the XXZ model, we show that entanglement as well as information theoretic measures violate the Benford's law. We quantitatively discuss the violation of the Benford's law by using a violation parameter, and demonstrate that the violation parameter can signal quantum phase transitions occurring in these models. We also comment on the universality of the statistics of first significant digits corresponding to appropriate measures of quantum correlations in the case of multipartite systems as well as systems in higher dimensions.Comment: v1: 11 pages, 5 figures, 2 tables; v2: 11 pages, 6 figures, 2 tables, new results added, extended version of the published pape

Mark My Words: The Trauma of Abducted Women in Two Short Stories by Ramapada Chaudhury

Since the paradigm shift that occurred in the 1990s, the human dimension of Partition has gained visibility within academia, chiefly with regard to abducted women. Their kidnapping, as well as the government measures adopted, deprived them of free will and intensified an already traumatic experience. This paper focuses on their representation in two short stories by Ramapada Chaudhury: “Embrace” and “The Stricken Daughter”. By drawing on trauma and affect theory, it highlights the individuality of the abducted despite their shared background and shows how seemingly opposite historical events—abduction and recovery—combine to bring about a gendered trauma. The ultimate aim is to prove that affection via words, or lack thereof, is the determining factor in the healing of wounds. // Desde el cambio de paradigma en los años 90, la dimensión humana de la Partición ha ganado visibilidad en el ámbito académico, principalmente con respecto a las mujeres secuestradas. Tanto su rapto como las medidas gubernamentales adoptadas las privaban de libre albedrío e intensificaban una experiencia ya de por sí traumática. Este artículo se centra en su representación en dos relatos de Ramapada Chaudhury: “Embrace” y “The Stricken Daughter”. Por medio de teoría del trauma y de afectos, se pone de relieve la individualidad de las secuestradas pese a su trasfondo común y se muestra que sucesos históricos aparentemente contrarios como el rapto y la recuperación se combinan para causar un trauma mediado por el género. El objetivo final es demostrar que el afecto a través de palabras (o la falta del mismo) es el factor determinante para cicatrizar heridas

The Carnegie Supernova Project. I. Third Photometry Data Release of Low-redshift Type Ia Supernovae and Other White Dwarf Explosions

We present final natural-system optical (ugriBV) and near-infrared (YJH) photometry of 134 supernovae (SNe) with probable white dwarf progenitors that were observed in 2004-2009 as part of the first stage of the Carnegie Supernova Project (CSP-I). The sample consists of 123 Type Ia SNe, 5 Type Iax SNe, 2 super-Chandrasekhar SN candidates, 2 Type Ia SNe interacting with circumstellar matter, and 2 SN 2006bt-like events. The redshifts of the objects range from to 0.0835; the median redshift is 0.0241. For 120 (90%) of these SNe, near-infrared photometry was obtained. Average optical extinction coefficients and color terms are derived and demonstrated to be stable during the five CSP-I observing campaigns. Measurements of the CSP-I near-infrared bandpasses are also described, and near-infrared color terms are estimated through synthetic photometry of stellar atmosphere models. Optical and near-infrared magnitudes of local sequences of tertiary standard stars for each supernova are given, and a new calibration of Y-band magnitudes of the Persson et al. standards in the CSP-I natural system is presented.Fil: Krisciunas, Kevin.

Artrosis postraumática en pacientes con fractura-luxacion de Lisfranc.

La artrosis postraumática es una de las complicaciones más frecuentes y más invalidantes de la fractura-luxación de Lisfranc (FLL). Objetivo . Evaluar el grado de incidencia de artrosis postraumática como complicación y secuela en pacientes con fractura-luxación de Lisfranc y valorar qué factores muestran relación directa o influyen en su aparición y desarrollo. Material y Método . Se realizó un estudio de cohortes ambispectivo transversal de 83 pacientes con diagnóstico de fractura-luxación de Lisfranc. Se utilizó un protocolo de recogida de datos con variables relacionadas con la lesión, parámetros clínicos, terapéuticos, complicaciones y escalas de valoración clínica. La valoración de artrosis se realiza mediante aparición de signos radiológicos de la clasifica - ción radiológica de Kellgren y Lawrence y su correlación clínica con presencia de dolor. Resultados . La artrosis se mostró como un factor influyente en los resultados, puntuaciones regulares y malas presentan mayor tasa de artrosis (p=0,001), y en cuanto al grado de artrosis, los casos más graves de artrosis se situaban en el grupo de puntuaciones malas (p=0,025). Este grupo de pacientes presentaron peores puntuaciones porque referían más dolor, mayor consumo de analgésicos, más limitación de las actividades de la vida diaria, de las actividades deportivas y limitación de la distancia caminada. Conclusiones . La artrosis se mostró como un factor influyente en los resultados (p=0,001). Los pacientes que desarrollaron artrosis tardaron más tiempo en reincorporarse a su empleo o actividad laboral previa, tenían un tiempo más demorado desde la cirugía al alta y mayor número total de incapacidades laborales y compensaciones económicas con respecto a los pacientes que no desarrollaron artrosis, siendo todos estos valores estadísticamente significativos.The posttraumatic degenerative osteoarthritis is one of the most frequent complications and more disabling of Lisfranc's fracture - luxation (FLL). Objetive. Evaluate the degree of frequency of posttraumatic degenerative osteoarthritis as complication and adverse effect in patients with Lisfranc's fracture - luxation and value what factors show straight relation or influence in its appearance and development. Material and Method.We have made a transversal prospective and retrospective study of cohorts on 83 patients with diagnosis of Lisfranc's fracture - luxation. We have used a data collecting protocol of items related to the injury, clinical, therapeutic parameters, complications and scales of clinical valuation. The assessment valuation of degenerative osteoarthritis is made under radiological signs realized by means of appearance of radiological signs of Kellgren and Lawrence classification and clinical correlation with presence of pain. Results . The degenerative osteoarthri tis appeared as an influential factor in the results, regular and bad punctuations present major rate of degenerative osteoarthritis (p=0,001), and as for the degree of degenerative osteoarthritis, the most serious cases of degenerative osteoarthritis were placing in the group of bad punctuations (p=0,025). This group of patients presented worse punctuations because they were recounting more pain, major consumption of analgesics, more limitation of the activities of the daily life, of the sports activities and limitation of the travelled distance. Conclusions . The degenerative osteoarthritis appeared as an influential factor in the results (p=0,001). The patients who developed degenerative osteoarthritis were late more time in coming back to his employment or labor previous activity; they had a time more delayed from the surgery to the discharge and major total number of labor disabilities and economic compensations with regard to the patients who did not develop degenerative osteoarthritis, being all these statistically significant values
