Kavli Affiliate: John Serences | Authors: Yixin Yuan, John Serences and Mikio Christian Aoi | Summary: Gradual changes in neural response patterns to the same stimulus over time, termed representational drift, have been widely observed across cortical areas. Drift is typically attributed to intrinsic neural dynamics driven by synaptic plasticity or turnover. Here we test […]
Kavli Affiliate: Edward Kolb | Summary:A new field, emphParticle Cosmology, emerged at the interface of elementary particle physics and cosmology in the last two decades of the 20th century. In this chapter of the emphProceedings of the 4th International Symposium on the History of Particle Physics, the Standard Model and Beyond I will review the […]
Kavli Affiliate: Clifford Kentros | Authors: Oscar M. T. Chadney, Matteo Guardamagna, Felix Dorr, Lucie A. L. Descamps, Federico Stella, Francesco Battaglia and Clifford G. Kentros | Summary: The hippocampus and its main input, the entorhinal cortex, are essential for memory formation, yet how they interact to do so remains unresolved. Hippocampal CA1 pyramidal neurons […]
Kavli Affiliate: Ulrich Sperhake | Summary:Einstein’s equations of general relativity are one of the most complicated set of equations in all of physics and, for all but idealized physical settings, can only be solved by numerical methods on high-performance computing systems. Generating such solutions is a veritable Odyssey in its own right with adventures across […]
Kavli Affiliate: Wei Min | Authors: Xinwen Liu, Xuemeng Li, Lele Xu, Mian Wei, Areej Niaz, Ye He and Wei Min | Summary: Molecular information is vital for imaging technology. Optical imaging acquires molecular specificity almost exclusively via labeling strategy, which is fundamentally constrained by limited multiplexing capacity, high running costs, and experimental complexity. Conversely, […]
Kavli Affiliate: James Analytis| Summary:We report a high-field thermodynamic study of the hyperhoneycomb Kitaev material $β$-Li$_2$IrO$_3$, using magnetotropic susceptibility to resolve its low-temperature field-angle phase diagram across the principal crystallographic planes in magnetic fields up to $60$ T. Rather than evolving directly from the low-field incommensurate state into a polarized regime, the system exhibits a […]
Kavli Affiliate: David Spergel | Summary:We introduce a physics-informed framework for learning finite-dimensional embeddings of solution families of partial differential equations. The method uses a multihead Physics-Informed Neural Network in which a shared body learns a latent manifold representing the solution space, while linear heads reconstruct individual solutions associated with different initial conditions. A head-orthogonalization […]
Kavli Affiliate: David W. Miller | Summary:In this work, we propose a unified approach for diagnosing misclassification and assessing the robustness of black-box classifiers. Central to our method is an optimization framework that modifies an instance so that the classifier predicts a specified target label, while ensuring that the modification remains easily explainable. The objective […]
Kavli Affiliate: Satoshi Shirai | Summary:The two-zero minor structure predicted by flavor symmetries is usually discussed as a tree-level relation among low-energy neutrino parameters. We point out that this relation can be significantly modified by radiative corrections even when the two-zero minor structure is enforced by an underlying symmetry at tree level. As a concrete […]
Kavli Affiliate: Bradford Benson | Summary:We present the first reconstruction of the cosmic microwave background (CMB) lensing potential from the SPT-3G Summer survey using two years of temperature data. The Summer survey has a total area of approximately 2640 deg$^2$, split into three fields covering 1210, 570, and 860 deg$^2$, respectively. A joint analysis of […]
