All-organic self-separating three-dimensionally nanoarchitected electrochemical energy storage devices

Posted by klaurent April 29, 2026May 12, 2026Cornell

Kavli Affiliate: Ulrich Wiesner | Summary:This work realizes a three-dimensionally (3D) nanoarchitected, all organic, "self-separating" lithium-ion electrochemical energy storage (EES) device that is cycled as a solid-state full cell. The device is enabled by a monolithic carbon anode with a co-continuous pore network, derived from the structure direction of resols by an ultra-large molar mass […]

Chronic subthreshold intermittent theta burst stimulation promotes structural axon initial segment plasticity in cortical neurons

Posted by dbos April 28, 2026May 12, 2026UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Emily S King, Liz Jaeschke-Angi, Hakuei Fujiyama, Wickliffe Abraham, Jennifer Rodger, John N Reynolds, Darren Clarke, Jamie L Beros and Alexander Tang | Summary: Repetitive transcranial magnetic stimulation (rTMS) is used widely in neuroscience to study and alter neural plasticity. The cellular mechanisms underlying the effect of rTMS on […]

Age-related morphological changes in the C57BL/6J mouse calvaria: implications for stereotaxic neurosurgery

Posted by dbos April 28, 2026May 12, 2026UCSF

Kavli Affiliate: Zachary Knight | Authors: Zachary A Knight and Heeun Jang | Summary: The mouse skull serves as the coordinate framework for stereotaxic neurosurgery, yet whether aging alters surgically critical calvarial geometry has not been examined. We measured three parameters in large cohorts of young (2-3 months) and aged (23-30 months) male and female […]

Fast radio burst dispersion is an unbiased tracer of matter on large scales

Posted by klaurent April 28, 2026May 12, 2026MIT

Kavli Affiliate: Kiyoshi Masui | Summary:The dispersion of fast radio bursts (FRBs) measures the column density of free electrons, tracing the diffuse ionized gas that contains more than $90%$ of all baryons. On linear scales the FRB dispersion field is an approximately unbiased tracer of the matter distribution, an idea long assumed in the FRB […]

Magnomechanical Coupling in Suspended 2D van der Waals Ferromagnets

Posted by klaurent April 28, 2026May 12, 2026Delft

Kavli Affiliate: Herre Van Der Zant | Summary:Magnomechanical systems provide a promising route for exploring coherent hybrid magnon-phonon interactions and hybrid information processing, but their realization has so far been limited by weak magnon-phonon coupling in conventional bulk platforms. We show that a suspended membrane of a two-dimensional van der Waals ferromagnet with in-plane magnetization […]

Lessons from binary dynamics of inspiralling equal-mass boson-star mergers

Posted by klaurent April 28, 2026May 12, 2026Cambridge

Kavli Affiliate: Ulrich Sperhake | Summary:We explore the gravitational-wave phenomenology of equal-mass inspiralling boson-star binaries using numerical relativity simulations. In particular, we characterise the waveform differences between binary boson-star and black-hole systems across (i) the early inspiral, by matching our waveforms to post-Newtonian expressions, (ii) merger, and (iii) late ringdown, by extracting the quasi-normal mode […]

Non-magnetic floating phases in frustrated Haldane chains with a single-ion anisotropy

Posted by klaurent April 28, 2026May 12, 2026Delft

Kavli Affiliate: Natalia Chepiga | Summary:We investigate the effect of a single-ion anisotropy on the bilinear-biquadratic spin-1 J1-J2 chain, focusing on the quantum phase transitions out of the trimerized phase. Using large-scale density matrix renormalization group simulations, we uncover a rich phase diagram comprising five gapped phases and, remarkably, two critical floating phases. These incommensurate […]

Stability of Multiplicities in Symmetry Breaking: The sl_2 Case

Posted by klaurent April 28, 2026May 12, 2026Tokyo

Kavli Affiliate: Toshiyuki Kobayashi | Summary:This expository paper explains, in the case of $mathfraksl_2$, the ideas introduced in the preprints (arXiv:2509.17007, 2604.22262), which develop a new framework for the study of multiplicities in branching laws of representations, with particular emphasis on their dependence on representation parameters. Taking the Lie algebra $mathfraksl_2$ as a guiding example, […]

Decoupling the AGN outflow and star-forming disk kinematics in the nuclear region of NGC 7582 with JWST NIRSpec and MIRI/MRS

Posted by klaurent April 27, 2026May 12, 2026Peking

Kavli Affiliate: Claudio Ricci | Summary:We present a detailed study of the inner regions of NGC~7582, a nearby Seyfert~2 galaxy, from the Galaxy Activity, Torus and Outflow Survey (GATOS). The galaxy hosts a circumnuclear star-forming disk and an AGN-driven biconical ionised outflow. Using JWST NIRSpec and MIRI/MRS integral-field spectroscopy, we analyse ionic emission lines spanning […]

Friedman | Authors: Zhaoyue Zhang, Alexandre Moura-Assis, Shanshan Liu, Alon Millet, Jordan Shaked, Divya Rajan, Hanan Alwaseem, Michael Isay-Del Viscio, Henrik Molina, Kivanc Birsoy and Jeffrey M. Friedman | Summary: While standard high fat diets cause hyperphagia and obesity in mice, high fat-low carbohydrate ketogenic diets (KDs) reduce food intake and […]
