Unbalanced L1 optimal transport for vector valued measures and application to Full Waveform Inversion

Optimal transport has recently started to be successfully employed to define misfit or loss functions in inverse problems. However, it is a problem intrinsically defined for positive (probability) measures and therefore strategies are needed for its…

Heterogeneities of the perceptual-motor style during locomotion at height

In a recent review, we summarized the characteristics of perceptual-motor style in humans. Style can vary from individual to individual, task to task and pathology to pathology, as sensorimotor transformations demonstrate considerable adaptability…

4D flow MRI aortic cross-sectional pressure changes and their associations with flow patterns in health and aneurysm

Background: Ascending thoracic aortic aneurysm (ATAA) is a potentially life-threatening dilation of the ascending aorta (AscAo) that often develops without symptoms. The current clinical practice relies on measuring the maximal diameter of the aorta…

Diffusion models meet image counter-forensics

From its acquisition in the camera sensors to its storage, different operations are performed to generate the final image. This pipeline imprints specific traces into the image to form a natural watermark. Tampering with an image disturbs these…

Real-Time Sign Language Recognition Based on Motion Gesture Identification Using Wireless Body Area Sensors

To improve the communication between deaf and hearing individuals using handheld devices, we propose a lightweight approach for the quick identification of words in American Sign Language (ASL). The main idea is to convert hand gestures of ASL into…

The bidirectional effects between cognitive ability and brain morphology: A life course Mendelian randomization analysis

Abstract Introduction Little is understood about the dynamic interplay between brain morphology and cognitive ability across the life course. Additionally, most existing research has focused on global morphology measures such as estimated total…
