MV-ComBat and MV-CovBat: Multivariate Frameworks for Joint Harmonization of Multi-Metric Neuroimaging Data

Posted by dbos February 9, 2026February 18, 2026Hopkins

Kavli Affiliate: Martin Lindquist | Authors: Zheng Ren, Patrick Sadil and Martin Lindquist | Summary: Aggregating neuroimaging data across sites and studies is increasingly common, yet site- and scanner-related batch effects can obscure meaningful biological variation and introduce spurious associations. Although ComBat and its extensions are widely used, they are primarily designed for single-metric (univariate) […]

Functional connectivity profile of the amygdala subfields associates with emotional well-being in aging

Posted by dbos February 9, 2026February 18, 2026NTNU

Kavli Affiliate: Maryam Ziaei and Menno Witter | Authors: Shuer Ye, Arjun Dave, Xiaqing Lan, Menno P. Witter, Alireza Salami and Maryam Ziaei | Summary: Amygdala-related functional connectivity plays a crucial role in human emotion, cognition, and mental well-being. The amygdala is a highly heterogeneous structure, with subregions that have both distinct and overlapping functions. […]

Balancing Stability and Flow in Hippocampal Networks via Inductive Bias and Learned Symmetry Breaking

Posted by dbos February 9, 2026February 23, 2026UCSD / Salk

Kavli Affiliate: Terrence Sejnowski | Authors: Margot Wagner, Yusi Chen, Arjun Karuvally, Mia Cameron and Terrence J Sejnowski | Summary: sequential dynamics underlying replay, prediction and traveling waves. How hippocampal circuitry achieves both remains unclear. Here, we show that recurrent neural networks trained on continuous prediction tasks converge to a mixed-symmetry dynamical regime, in which […]

Transient Relativistic Iron Emission Line from an X-ray Flaring Supermassive Black Hole

Posted by klaurent February 9, 2026MIT

Kavli Affiliate: Erin Kara | Summary:We report the discovery of the first transient relativistic iron Kα line in an Active Galactic Nucleus (AGN) J1047+5907. The line was detected 21.5 days (rest-frame) after an X-ray coronal flare observed in 2008 and it exhibits significant broadening consistent with relativistic reflection from the accretion disk in the vicinity […]

Coherence Protection for Mobile Spin Qubits in Silicon

Posted by klaurent February 9, 2026February 23, 2026Delft

Kavli Affiliate: Lieven Vandersypen | Summary:Mobile spin qubit architectures promise flexible connectivity for efficient quantum error correction and relaxed device layout constraints, but their viability rests on preserving spin coherence during transport. While shuttling transforms spatial disorder into time-dependent noise, its net impact on spin coherence remains an open question. Here we demonstrate systematic noise […]

Unraveling the mysteries of Jets in peculiar NLSy1 galaxies through multi-wavelength variability

Posted by klaurent February 9, 2026February 23, 2026Peking

Kavli Affiliate: Luis Ho | Summary:Radio-quiet narrow-line Seyfert 1 galaxies (RQ-NLSy1s) are generally considered to be dominated by thermal emission from the accretion disk. However, recurring 37 GHz radio flares detected from seven RQ-NLSy1s by the Metsahovi Radio Observatory suggest that non-thermal processes may also contribute to their emission. We present a systematic optical and […]
