TLDR
The main focus in MUCKE is on cleaning large scale Web image corpora and on proposing image representations which are closer to the human interpretation of images.Abstract:
MUCKE aims to mine a large volume of images, to structure them conceptually and to use this conceptual structuring in order to improve large-scale image retrieval. The last decade witnessed important progress concerning low-level image representations. However, there are a number problems which need to be solved in order to unleash the full potential of image mining in applications. The central problem with low-level representations is the mismatch between them and the human interpretation of image content. This problem can be instantiated, for instance, by the incapability of existing descriptors to capture spatial relationships between the concepts represented or by their incapability to convey an explanation of why two images are similar in a content-based image retrieval framework. We start by assessing existing local descriptors for image classification and by proposing to use co-occurrence matrices to better capture spatial relationships in images. The main focus in MUCKE is on cleaning large scale Web image corpora and on proposing image representations which are closer to the human interpretation of images. Consequently, we introduce methods which tackle these two problems and compare results to state of the art methods. Note: some aspects of this deliverable are withheld at this time as they are pending review. Please contact the authors for a preview.read more

Comparison of Egg Fertility Identification based on GLCM Feature Extraction using Backpropagation and K-means Clustering Algorithms
TL;DR: The results show that the Backpropagation algorithm (using 12 hidden layer neurons) provides a 93% accuracy rate, while the K-means clustering algorithm presents a 74% accuracy rates.

Characterization of the Pseudomonas aeruginosa NQR complex, a bacterial proton pump with roles in autopoisoning resistance.
Daniel A. Raba,Monica Rosas-Lemus,William M. Menzer,Chen Li,Xuan Fang,Pingdong Liang,Karina Tuz,David D. L. Minh,Oscar Juárez +8 more
TL;DR: It is indicated that Pa-NQR is a proton pump rather than a sodium pump and is highly resistant against the P. aeruginosa–produced compound HQNO, suggesting an important role in the adaptation against autotoxicity.

Pupal cannibalism by worker honey bees contributes to the spread of deformed wing virus.

TL;DR: It is demonstrated that cannibalization of DWV-infected pupae resulted in high levels of this virus in worker bees and that the acquired virus was then transmitted between bees via trophallaxis, allowing circulation of Varroa-vectored DWV variants without the mites.

Molecular characterization of Neospora caninum MAG1, a dense granule protein secreted into the parasitophorous vacuole, and associated with the cyst wall and the cyst matrix
TL;DR: In both tachyzoites and bradyzoites, Nc MAG1 was associated with the parasite dense granules, and comparison between NcMAG1 and TgMAG1 amino acid sequences revealed that the C-terminal conserved regions exhibit 66% identity, while the N- terminal variable regions exhibit only 32% identity.

TL;DR: In this article, the authors assessed infaunal diversity and density between intertidal mudflats, sandflats and clam gardens and found that the differences in community composition were found among site types, with certain taxa including culturally important species increasing within clam gardens.
