TL;DR: An algorithm for view synthesis from an irregular grid of sampled views that first expands each sampled view into a local light field via a multiplane image (MPI) scene representation, then renders novel views by blending adjacent local light fields.
Abstract: We present a practical and robust deep learning solution for capturing and rendering novel views of complex real world scenes for virtual exploration. Previous approaches either require intractably dense view sampling or provide little to no guidance for how users should sample views of a scene to reliably render high-quality novel views. Instead, we propose an algorithm for view synthesis from an irregular grid of sampled views that first expands each sampled view into a local light field via a multiplane image (MPI) scene representation, then renders novel views by blending adjacent local light fields. We extend traditional plenoptic sampling theory to derive a bound that specifies precisely how densely users should sample views of a given scene when using our algorithm. In practice, we apply this bound to capture and render views of real world scenes that achieve the perceptual quality of Nyquist rate view sampling while using up to 4000x fewer views. We demonstrate our approach's practicality with an augmented reality smartphone app that guides users to capture input images of a scene and viewers that enable realtime virtual exploration on desktop and mobile platforms.

TL;DR: In this paper, the first chemical vapor deposition growth of single and few-layer MoSe2 nanosheets was reported, which can be directly grown on the 300 nm SiO2/Si substrates.
Abstract: The synthesis of two-dimensional (2D) layered materials with controllable thickness is of considerable interest for diverse applications. Here we report the first chemical vapor deposition growth of single- and few-layer MoSe2 nanosheets. By using Se and MoO3 as the chemical vapor supply, we demonstrate that highly crystalline MoSe2 can be directly grown on the 300 nm SiO2/Si substrates to form optically distinguishable single- and multi-layer nanosheets, typically in triangular shaped domains with edge lengths around 30 μm, which can merge into continuous thin films upon further growth. Micro-Raman spectroscopy and imaging was used to probe the thickness-dependent vibrational properties. Photoluminescence spectroscopy demonstrates that MoSe2 monolayers exhibit strong near band edge emission at 1.55 eV, while bilayers or multi-layers exhibit much weaker emission, indicating of the transition to a direct band gap semiconductor as the thickness is reduced to a monolayer.

TL;DR: Las guias basadas en datos y pruebas cientificas comprenden el diagnóstico, el tratamiento and the quimioprofilaxis with medicamentos antivirales, además de temas relacionados with the control of brotes de influenza estacional (interpandémicas) en ámbitos institucionales.
Abstract: 14 Universidad de Toronto, Ontario, Canada. Es importante advertir que, en las guo´as, no es posible tener en cuenta siempre las variaciones individuales que se presenten entre pacientes. Las guo´as no intentan reemplazar el criterio del medico respecto de pacientes en particular o cuadros clo´nicos especiales. La Sociedad de Enfermedades Infecciosas de Estados Unidos de America considera que la adhesion a estas guo´as es voluntaria y que la determinacion final sobre su aplicacion corresponde al medico conforme a la situacion individual de cada paciente. Los hallazgos y las conclusiones de este informe pertenecen a los autores y no representan, necesariamente, la postura oficial de los Centros para el Control y Prevencion de Enfermedades.

TL;DR: In this paper, the effects of non-planarity on the fracture resistance locus of interfaces has been investigated using a simple model of contacting facets along the crack surface, which resist the motion of the crack surfaces by means of friction and locking and thereby modify the energy release rate at the crack front.
