FROM PANORAMIC PHOTOS TO A LOW-COST PHOTOGRAMMETRIC WORKFLOW FOR CULTURAL HERITAGE 3D DOCUMENTATION
The research aims to optimize a workflow of architecture documentation: starting from panoramic photos, tackling available instruments and technologies to propose an integrated, quick and low-cost solution of Virtual Architecture. The broader research background shows how to use spherical panoramic images for the architectural metric survey. The input data (oriented panoramic photos), the level of reliability and Image-based Modeling methods constitute an integrated and flexible 3D reconstruction approach: from the professional survey of cultural heritage to its communication in virtual museum. The proposed work results from the integration and implementation of different techniques (Multi-Image Spherical Photogrammetry, Structure from Motion, Imagebased Modeling) with the aim to achieve high metric accuracy and photorealistic performance. Different documentation chances are possible within the proposed workflow: from the virtual navigation of spherical panoramas to complex solutions of simulation and virtual reconstruction. VR tools make for the integration of different technologies and the development of new solutions for virtual navigation. Image-based Modeling techniques allow 3D model reconstruction with photo realistic and high-resolution texture. High resolution of panoramic photo and algorithms of panorama orientation and photogrammetric restitution vouch high accuracy and high-resolution texture. Automated techniques and their following integration are subject of this research. Data, advisably processed and integrated, provide different levels of analysis and virtual reconstruction joining the photogrammetric accuracy to the photorealistic performance of the shaped surfaces. Lastly, a new solution of virtual navigation is tested. Inside the same environment, it proposes the chance to interact with high resolution oriented spherical panorama and 3D reconstructed model at once

The role of angular momentum in the construction of electromagnetic multipolar fields
Multipolar solutions of Maxwell's equations are used in many practical
applications and are essential for the understanding of light-matter
interactions at the fundamental level. Unlike the set of plane wave solutions
of electromagnetic fields, the multipolar solutions do not share a standard
derivation or notation. As a result, expressions originating from different
derivations can be difficult to compare. Some of the derivations of the
multipolar solutions do not explicitly show their relation to the angular
momentum operators, thus hiding important properties of these solutions. In
this article, the relation between two of the most common derivations of this
set of solutions is explicitly shown and their relation to the angular momentum
operators is exposed.Comment: 13 pages, 2 figure
Variabilidade genética de Phakopsora pachyrhizi avaliada por meio de marcadores microssatélites.
O objetivo deste trabalho foi avaliar a variabilidade genética da ferrugem?asiática?da?soja no Brasil, com uso de marcadores microssatélites. Populações de esporos de Phakopsora pachyrhizi coletadas nas regiões Sul, Sudeste e Centro Oeste do país foram submetidas à análise de variabilidade genética, avaliada por meio de marcadores microssatélites específicos para o fungo. Foram coletadas, também, populações de fungo em diversas variedades de soja em uma mesma localidade, incluindo populações com lesão ?reddish?brown? (RB). Entre essas populações, não houve variabilidade. Tecidos com lesões RB não apresentaram esporos do fungo e não amplificaram com os marcadores específicos para P. pachyrhizi. A variabilidade genética entre as populações coletadas nas três regiões variou de 0 a 0,36. Observou-se tendência de agrupamento das populações da região Sul e Centro Oeste do Brasil em grupos diferentes. A existência de variabilidade genética em populações de P. pachyrhizi é um indicativo de que a resistência genética vertical, conferida por genes únicos, é uma estratégia de risco para os programas de melhoramento genético que visam a resistência à ferrugem?asiática?da?soja no Brasil
Spectropolarimetric measurements of hidden broad lines in nearby megamaser galaxies: a lack of clear evidence for a correlation between black hole masses and virial products
High-accuracy black hole (BH) masses require excellent spatial resolution
that is only achievable for galaxies within ~100 Mpc using present-day
technology. At larger distances, BH masses are often estimated with
single-epoch scaling relations for active galactic nuclei. This method requires
only luminosity and the velocity dispersion of the broad line region (BLR) to
calculate a virial product, and an additional virial factor, , to determine
BH mass. The accuracy of these single-epoch masses, however, is unknown, and
there are few empirical constraints on the variance of between objects. We
attempt to calibrate single-epoch BH masses using spectropolarimetric
measurements of nine megamaser galaxies from which we measure the velocity
distribution of the BLR. We do not find strong evidence for a correlation
between the virial products used for single-epoch masses and dynamical mass,
both for the megamaser sample alone and when combined with dynamical masses
from reverberation mapping modeling. Furthermore, we find evidence that the
virial parameter varies between objects, but we do not find strong evidence
for a correlation with other observable parameters such as luminosity or broad
line width. Although we cannot definitively rule out the existence of any
correlation between dynamical mass and virial product, we find tension between
allowed values for masers and those widely used in the literature. We
conclude that the single-epoch method requires further investigation if it is
to be used successfully to infer BH masses.Comment: 27 pages, 16 figures, resubmitted to ApJ after incorporating
