MULTI-MAP FUSION FOR WEAKLY SUPERVISED DISEASE LOCALIZATION FROM GLOBALLY ASSIGNED DIAGNOSTIC LABELS IN BRAIN MRI

Seoyoung Oh, Mélanie Pélégrini-Issac, Hélène Urien, Veronique Marchand-Pauvert, Jérémie Sublime

Deep learning for brain MRI analysis is often limited by the need for dense voxelwise annotations, which are costly and unreliable for subtle abnormalities. We propose GALA-Former, a weakly supervised Transformer-based framework that localizes disease-relevant regions using only subjectlevel…

Sulfate phantoms to mimic NIR photoacoustic response of whole blood at selected oxygen saturations

Léa Davenet, Arthur Billon, Jacques Battaglia, S. Lori Bridal, Jérôme Gateau

This paper presents a practical guide to prepare inorganic solutions that mimic the photoacoustic properties of whole blood at specific levels of oxygenation in the range of 700 nm to 850 nm, both in terms of optical absorption properties and the Grüneisen coefficient. The goal is to provide…

What do the main reported findings from the 20-item Dysexecutive Questionnaire (DEX) tell us? The valence-bias hypothesis

Hugo Câmara-Costa, Mathilde Chevignard, Philippe Azouvi, Georges Dellatolas

The valence-bias hypothesis refers to the tendency of some respondents to answer according to the positive/negative polarity of a question (its valence) rather than its specific content, potentially reducing the specificity of psychological and neuropsychological questionnaires, and increase…

Mechanical and Growth Anisotropy in <i>Chara corallina</i> : Challenging Green’s Hypothesis

Weiyuan Kong, Antonio Mosciatti, Jerome Boulanger, Guillaume Marrelec, Thierry Savy, Etienne Couturier

<div><p>Paul Green hypothesized that growth anisotropy of plant cylindrical organs could be controlled by cell-wall elastic strain. The present study aimed to challenge this hypothesis through a robust experimental and analytical framework. By combining live-cell imaging of C. corallina…
