Image Mosaic

We employ Convolutional Neural Networks with the VGG16 and VGG19 architecture to classify photographs that span four decades of professional photographic work by Mário Cabrita Gil. For each photograph, the 4096 dimension feature vector is reduced to two-dimensions by employing distributed Stochast Neighbor Embedding (t-SNE). Finally, the photographs are arranged according to their similarity va...

Explorer MOSAIC

Background: The recent availability of complete sequences for numerous closely related bacterial genomes opens up new challenges in comparative genomics. Several methods have been developed to align complete genomes at the nucleotide level but their use and the biological interpretation of results are not straightforward. It is therefore necessary to develop new resources to access, analyze, an...

Characterization of Celery Mosaic Virus from Celery in Tehran Province

Background and Aims: Celery mosaic virus (CeMV) is one of the causal agents of viral diseases in celery (Apium graveolens). CeMV is a member of the Potyvirus genus in Potyviridae family. The virus is naturally transmitted by aphids in a non-persistent manner. During growing season 2006-2007 viral disease symptoms were observed in celery fields grown in Tehran Province (Bage daneshkade, Mohamads...

Adequacy assessment of mathematical models in the dynamics of litter decomposition in a tropical forest Mosaic Atlantic, in southeastern Brazil.

The study of litter decomposition and nutrient cycling is essential to know native forests structure and functioning. Mathematical models can help to understand the local and temporal litter fall variations and their environmental variables relationships. The objective of this study was test the adequacy of mathematical models for leaf litter decomposition in the Atlantic Forest in southeastern...
