Beyond the LUMIR challenge: The pathway to foundational registration models

Posted by klaurent Chicago

Kavli Affiliate: Hsiaowen Chen| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Medical image challenges have played a transformative role in advancing the field, catalyzing innovation and establishing new performance benchmarks. Image registration, a foundational task in neuroimaging, has similarly advanced through the Learn2Reg initiative. Building on this, we introduce the Large-scale Unsupervised Brain MRI […]

Development of a Charge-Resistant Embedding Media for High-Performance Serial Block Face Imaging of Cells and Tissues

Posted by dbos UCSD / Salk

Kavli Affiliate: Mark Ellisman | Authors: Thomas Deerinck, Steven Peltier and Mark Ellisman | Summary: Serial block-face scanning electron microscopy (SBEM) enables high-resolution 3D imaging of biological specimens but is often limited by specimen charging due to the use of non-conductive epoxy resins. While heavy metal staining and variable-pressure SEM can reduce charging, these methods […]

The shape of attention: How cognitive goals sculpt cortical representation of speech.

Posted by dbos Hopkins

Kavli Affiliate: Mounya Elhilali | Authors: Moïra-Phoebé Huet and Mounya Elhilali | Summary: Perception requires more than passive sensing—it involves prioritizing the features most relevant to ongoing cognitive goals, a process guided by selective attention. A central question is whether attention operates by enhancing all features of a selected target, or by optimizing neural encoding […]

Black hole spectroscopy: from theory to experiment

Posted by klaurent MIT

Kavli Affiliate: Scott A. Hughes | Summary:The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes and comparing them with gravitational-wave data from compact binary mergers we can advance our understanding of the two-body problem in general relativity, verify the predictions […]

On the Convergence Analysis of Muon

Posted by klaurent Cornell

Kavli Affiliate: Kyle Shen | First 5 Authors: Wei Shen, Wei Shen, , , | Summary: The majority of parameters in neural networks are naturally represented as matrices. However, most commonly used optimizers treat these matrix parameters as flattened vectors during optimization, potentially overlooking their inherent structural properties. Recently, an optimizer called Muon has been […]

Measuring topological invariants of even-dimensional line-gapped non-Hermitian systems through quench dynamics

Posted by klaurent UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Xiao-Dong Lin, Xiao-Dong Lin, , , | Summary: The accurate determination of non-Hermitian (NH) topological invariants plays a central role in the study of NH topological phases. In this work, we propose a general framework for directly measuring NH topological invariants in even-dimensional systems with real line […]
