3D video coding and transmission

The capture, transmission, and display of 3D content has gained a lot of attention in the last few years. 3D multimedia content is no longer con fined to cinema theatres but is being transmitted using stereoscopic video over satellite, shared on Blu-RayTMdisks, or sent over Internet technologies. Stereoscopic displays are needed at the receiving end and the viewer needs to wear special glasses to present the two versions of the video to the human vision system that then generates the 3D illusion. To be more e ffective and improve the immersive experience, more views are acquired from a larger number of cameras and presented on di fferent displays, such as autostereoscopic and light field displays. These multiple views, combined with depth data, also allow enhanced user experiences and new forms of interaction with the 3D content from virtual viewpoints. This type of audiovisual information is represented by a huge amount of data that needs to be compressed and transmitted over bandwidth-limited channels. Part of the COST Action IC1105 \3D Content Creation, Coding and Transmission over Future Media Networks" (3DConTourNet) focuses on this research challenge.peer-reviewe

Morpho/Proteomic Comparative between High Grade Pleomorphic Sarcoma and Metastasis Diagnosed in an Old Captive Common Hippo

Old age is a risk factor for cancer development in humans and animals, and studies have shown that tumors in animals are acceptable models for studying human cancers, considering the similarities between their factors. This work was conducted in a 53-year-old captive female common hippo (Hippopotamus amphibious) with a left leg tumor and metastatic mass. Histopathological and immunohistochemical analyses were carried out with a final diagnosis of a high grade pleomorphic sarcoma. A proteomic study using mass spectrometry was added in order to identify further aspects of the primary tumor and metastasis which could improve our understanding, and each tissue showed a proteomic profile indicative of its pathologic state with significant differences between healthy tissue, primary and metastatic tumors. Low levels of beta-actin in primary tumors were identified, and this may be associated with a possible consequence of cytoskeleton dynamic modification. In metastatic tissue, these dynamics may be affected by the presence of HSP chaperone 60.FAPESP: 2012/02514-9Univ Fed Sao Paulo, Inst Ciencias Ambientais Quim & Farmaceut, BR-04039032 Diadema, SP, BrazilUniv Fed Sao Paulo, Escola Paulista Med, BR-04023062 Sao Paulo, SP, BrazilAC Camargo Canc Ctr, Dept Patol, BR-01509010 Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Inst Ciencias Ambientais Quim & Farmaceut, BR-04039032 Diadema, SP, BrazilUniv Fed Sao Paulo, Escola Paulista Med, BR-04023062 Sao Paulo, SP, BrazilWeb of Scienc

Cross sections relevant to gamma-ray line emission in solar flares:3^3He-induced reactions on 16^{16}O nuclei

Gamma-ray production cross sections have been measured for gamma-ray lines copiously emitted in the $^3$He bombardment of $^{16}$O nuclei: the 937, 1042 and 1081 keV lines of $^{18}$F and the 1887 keV line of $^{18}$Ne. Four Ge detectors with BGO shielding for Compton suppression were used to measure the angular distributions of the gamma-rays. The excitation functions have been obtained for $^3$He bombarding energies from 3.7 to 36 MeV. Total cross sections are tabulated for calculations relevant to gamma-ray astronomy. The importance of these lines as diagnosis for the presence and properties of accelerated $^3$He in solar flares is discussed in light of the measured cross sections.Comment: Phys. Rev.

A new experiment for the determination of the 18F(p,alpha) reaction rate at nova temperatures

The 18F(p,alpha) reaction was recognized as one of the most important for gamma ray astronomy in novae as it governs the early 511 keV emission. However, its rate remains largely uncertain at nova temperatures. A direct measurement of the cross section over the full range of nova energies is impossible because of its vanishing value at low energy and of the short 18F lifetime. Therefore, in order to better constrain this reaction rate, we have performed an indirect experiment taking advantage of the availability of a high purity and intense radioactive 18F beam at the Louvain La Neuve RIB facility. We present here the first results of the data analysis and discuss the consequences.Comment: Contribution to the Classical Novae Explosions conference, Sitges, Spain, 20-24 May 2002, 5 pages, 3 figure

Comportamento de duas cultivares de mandioca tipo mesa submetidas a três métodos de conservação pós-colheita.

Foi conduzido um estudo com objetivo de avaliar os tempos de cocção de raízes de duas cultivares de mandioca tipo mesa submentidas a métodos de conservação pós-colheita e a determinação das taxas de deterioração das raízes nas 72 horas após a colheita. As plantas foram cultivadas no município de Santa Luzia do Norte, AL. As avaliações foram realizadas no Galpão de Processamento da Embrapa Tabuleiros Costeiros na cidade de Rio Largo/AL. Sob condições de armazenamento ambiental não houve diferença entre as cultivares em termos de tempo de cocção. A cultivar Recife apresentou menor tempo de cocção quando as raízes foram armazenadas sob congelamento As raízes da Rosinha apresentaram taxas de deterioração superiores às raízes da Recife nas condições do presente estudo

Identificacao de fontes de resistencia em cebola ao fungo Collitotrichum gloeosporioides.

A antracnose foliar se destaca como uma das principais doencas no cultivo da cebola nas regioes produtores do submedio Sao Francisco. Na tentativa de minimizar as perdas ocasionadas no campo, o trabalho teve como principal objetivo identificar fontes de resistencia de cultivares de cebola ao fungo C. gloeosporioides em experimento de casa-de-vegetacao utilizando as cvs. IPA 9, Roxa IPA 3, Franciscana IPA 10, Vale Ouro IPA 11, Brownsville, IPA 6, Red Creole, Texas Early Grano 502 e Roxinha de Belem. Aos sessenta dias apos o plantio, quando todas as plantulas estavam com a quarta folha verdadeira, fez-se a inoculacao por aspersao (1 x 10(6) conidios/ml) utilizando-se 15 isolados do patogeno, coletados nas diferentes areas produtoras do estado de Pernambuco e Bahia. As avaliacoes foram feitas aos 3, 6, 9 e 12 dias apos a inoculacao utilizando-se uma escada de notas variando de 0 a 4. As cultivares mais suscetiveis foram: Texas Early Grano 502, Brownsville e Red Creole, enquanto que, Vale Ouro IPA 11, IPA 9 e Roxa IPA 3 comportaram-se como as mais resistentes.Suplemento.
