Utilising semantic technologies for intelligent indexing and retrieval of digital images [PDF]

, 2013
The proliferation of digital media has led to a huge interest in classifying and indexing media objects for generic search and usage. In particular, we are witnessing colossal growth in digital image repositories that are difficult to navigate using free-

A Hybrid Model for Automatic Image Annotation

Proceedings of International Conference on Multimedia Retrieval, 2014
In this work, we present a hybrid model (SVM-DMBRM) combining a generative and a discriminative model for the image annotation task. A support vector machine (SVM) is used as the discriminative model and a Discrete Multiple Bernoulli Relevance Model (DMBRM) is used as the generative model.

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Model for Automatic Image Annotation Leveraging the OnTunAr Ontology

Computing Open
In this paper, we present the Automatic Annotation of Archaeological Images model. However, this model is composed of several methods for the analysis, description, and recognition of image components to improve the automatic annotation. Also, the latter

Multilabel Image Annotation Based on Double-Layer PLSA Model

The Scientific World Journal, 2014
Due to the semantic gap between visual features and semantic concepts, automatic image annotation has become a difficult issue in computer vision recently.

Astrocyte heterogeneity in brain metastases

Molecular Oncology, EarlyView.
Astrocytes emerge as pivotal regulators of metastatic colonization, survival, immune remodeling, and therapy response associated with an increasing heterogeneity that requires spatially and longitudinally resolved approaches to uncover regulatory programs and guide context‐specific therapies.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Automatic detection, segmentation, and characterization of 3-nitro-1,2,4-triazol-5-one (NTO) crystal particles during cooling crystallization using deep learning

Energetic Materials Frontiers
The complex cooling crystallization process of 3-nitro-1,2,4-triazol-5-one (NTO) directly affects its performance. The introduction of process analysis technology is expected to provide an effective solution for process monitoring and optimization.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
