Frontoparietal functional dedifferentiation during naturalistic movie watching among older adults at risk of emotional vulnerability

Posted by dbos NTNU

Kavli Affiliate: Maryam Ziaei | Authors: Shuer Ye, Arjun Dave, Alireza Salami and Maryam Ziaei | Summary: Functional dedifferentiation, a hallmark of brain aging particularly evident within the frontoparietal network (FPN), has been extensively investigated in the context of cognitive decline, yet its implications for late-life mental health remain poorly understood. Leveraging naturalistic fMRI combined […]

WeGA: Weakly-Supervised Global-Local Affinity Learning Framework for Lymph Node Metastasis Prediction in Rectal Cancer

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Yifan Gao, Yaoxian Dong, Wenbin Wu, Chaoyang Ge, Feng Yuan | Summary: Accurate lymph node metastasis (LNM) assessment in rectal cancer is essential for treatment planning, yet current MRI-based evaluation shows unsatisfactory accuracy, leading to suboptimal clinical decisions. Developing automated systems also faces significant obstacles, primarily the […]

Symbolic Learning of Topological Bands in Photonic Crystals

Posted by klaurent MIT

Kavli Affiliate: Max Tegmark | Summary:Topological photonic crystals (PhCs) that support disorder-resistant modes, protected degeneracies, and robust transport have recently been explored for applications in waveguiding, optical isolation, light trapping, and lasing. However, designing PhCs with prescribed topological properties remains challenging because of the highly nonlinear mapping from the continuous real-space design of PhCs to […]

Plasticity as the Mirror of Empowerment

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel| First 5 Authors: David Abel, David Abel, , , | Summary:Agents are minimally entities that are influenced by their past observations and act to influence future observations. This latter capacity is captured by empowerment, which has served as a vital framing concept across artificial intelligence and cognitive science. This former capacity, […]

Origin of the ring ellipticity in the black hole images of M87*

Posted by klaurent Chicago

Kavli Affiliate: John Carlstrom | Summary:We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astrophysical, and imaging effects. Leveraging the enhanced capabilities of the Event Horizon Telescope (EHT) 2018 array, including improved $(u,v)$-coverage from the Greenland Telescope, we measure […]

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

Posted by klaurent MIT

Kavli Affiliate: Michael Fausnaugh | Summary:Though missions such as Kepler, K2, and TESS have discovered $>$2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P$lesssim$3 days) orbits. This feature, called the Neptune desert or the evaporation desert, is believed to be primarily shaped by planetary migration and photoevaporation. However, this […]

Whitened Score Diffusion: A Structured Prior for Imaging Inverse Problems

Posted by klaurent Cornell

Kavli Affiliate: Zhiting Tian | First 5 Authors: Jeffrey Alido, Jeffrey Alido, , , | Summary: Conventional score-based diffusion models (DMs) may struggle with anisotropic Gaussian diffusion processes due to the required inversion of covariance matrices in the denoising score matching training objective citevincent_connection_2011. We propose Whitened Score (WS) diffusion models, a novel framework based […]
