A high prevalence of the BRAFV600E somatic mutation was recently reported in several series of papillary thyroid carcinomas (PTC). This mutation appears to be particularly prevalent in PTC with a predominantly papillary architecture. Another BRAF mutation (K601E) was detected in a follicular adenoma and in some cases of the follicular variant of PTC. The(More)
The multimedia content delivery chain poses today many challenges. The increasing terminal diversity, network heterogeneity and the pressure to satisfy the user preferences are raising the need for content to be customized in order to provide the user the best possible experience. This paper addresses the problem of multimedia customization by (1)(More)
Follicular thyroid carcinoma is being diagnosed less and less frequently despite the increasing incidence of well-differentiated thyroid carcinomas everywhere. This review will discuss the reasons underlying such an observation focusing on the evolution of the morphological and immunohistochemical diagnostic criteria of follicular thyroid tumors. It will(More)
The BRAF gene has been shown to be a major target for mutations in papillary thyroid carcinoma (PTC) (36-69%), which forms almost all of the over 2000 cases of thyroid carcinoma that have occurred in Chernobyl. BRAF is activated by point mutation, and were it to occur at a high frequency in Chernobyl-related tumors, it would challenge the dominant role of(More)
BRAF gene mutations have been frequently detected in papillary thyroid carcinoma (PTC). Moreover, there is a close association between the type of mutation and the PTC histotype: BRAF(V600E) is associated with conventional PTC and with histological variants of PTC displaying a prominent papillary growth pattern, whereas BRAF(K601E) is associated with the(More)
We describe our experiments for the shot boundary detection, high-level feature extraction , search and story boundary detection tasks. In the shot boundary detection task, we employ our proven method based on the calculation of distances between colour histograms of frames over a range of timescales. In the feature detection task we confined our effort to(More)
In this paper we describe the geographic information retrieval system developed and results achieved by the Multimedia & Information Systems team for GeoCLEF 2006. We detail our methods for generating and applying co-occurrence models for the purpose of place name disambiguation, our use of named entity recognition tools and text indexing applications. The(More)
The existence of well-differentiated thyroid tumors sharing the clinicopathologic features of follicular and papillary carcinoma is discussed using the so-called diffuse (multinodular) form of the follicular variant of papillary carcinoma as a paradigm. Although the concept of a hybrid carcinoma of the thyroid is intellectually very appealing, we conclude(More)
This paper describes the participation of the NovaSearch group at TREC Clinical Decision Support 2015. For this year's task, we extended our rank fusion experiments from last year's edition using a supervised Learning to Fuse technique. Learning to Fuse is a technique that incrementally combines multiple runs that use different retrieval algorithms,(More)
