Mammographic risk assessment provides an indication of the likelihood of women developing breast cancer. Anumber ofmammographic image based classification methods have been developed, such as Wolfe, Boyd, BI-RADS and Tabár based assessment. We provide a comparative study of these four approaches. Results on the full MIAS database are presented, which indicate strong correlation (Spearman’s > 0....

Many relations between model elements are expressed in OCL. However, tool support to enable synchronization of elements based on OCL-expressed relations is lacking. In this paper, we propose to use active operations in order to achieve incremental execution of some OCL expressions. Moreover, bidirectionality can also be achieved in non-trivial

This paper demonstrates the existence of bi-directional relationships between interfirm collaboration and business sales. Entry and post-entry collaboration often contribute to superior performance, which in turn attracts more partners. At the same time, though, collaboration may impose constraints on growth opportunities. The relationships vary across types of collaborators and collaborations ...

Th rough their multiple roles in tourism, residents of destination communities interact with tourists at destinations. Th e consequences of these host-guest interactions are bi-directional. Much research has been done on impacts of host-guest interactions on the local community. On the other hand, few studies have evaluated how tourists' on-site behaviour and experiences are aff ected by such i...

The researchers reviewed 1,523 consecutive breast MRI exams performed from Jan. 1, 2003, to June 30, 2005, to identify all lesions initially detected on MRI and assessed as BI-RADS 4 or 5 for which the patient underwent subsequent imaging-guided needle or excisional biopsy. They recorded BI-RADS lesion features for each case and the risk of malignancy was assessed using generalized estimating e...

Introduction: Theranostic nanoparticles, which integrate both diagnostic and therapeutic capabilities into one nanoagent, has great promise to ablate more effective tumoral tissue by optimizing and real-time monitoring treatment interventions, as well as monitoring therapeutic response to corresponding effect. Multifunctional theranostic nanoagent based on graphene quantum dots...

This paper describes a corpus of conversations recorded using an extension of the DiapixUK task: the Diapix Foreign Language corpus (DIAPIX-FL) . English and Spanish native talkers were recorded speaking both English and Spanish. The bidirectionality of the corpus makes it possible to separate language (English or Spanish) from speaking in a first language (L1) or second language (L2). An acous...
