Instantons on ALE spaces for classical groups, involutions on quiver varieties, and quantum symmetric pairs

Posted by klaurent Tokyo

Kavli Affiliate: Hiraku Nakajima | Summary:Moduli spaces of instantons on ALE spaces for classical groups are examples of fixed point sets of involutions on quiver varieties, i.e., $σ$-quiver varieties. In 2018 Yiqiang Li considered their equivariant cohomology, and by stable envelope of Maulik-Okounkov, constructed representations of coideal subalgebras of Maulik-Okounkov Yangian, called twisted Yangian. We […]

When Tiny Halos Stir Spacetime: Gravitational Waves from Fifth-Force Mergers

Posted by klaurent Tokyo

Kavli Affiliate: Misao Sasaki | Summary:Dark matter fermions interacting via attractive fifth forces mediated by a light mediator can form dark matter halos in the very early universe. We show that bound systems composed of these halos are capable of generating gravitational wave (GW) signals detectable today, even when the individual halos are very light. […]

Endothelial type I interferon signaling modulates the vascular response to ischemic brain injury Kavli Affiliate: Vanessa Ruta | Authors: Philipp Brand, Katherine Keller, Rory T. Coleman, Noelle B. Eghbali, Sarah Zylka, Lucia L. Prieto-Godino and Vanessa Ruta | Summary: Mating decisions are often attributed to the sensory signaling between prospective sexual partners. Yet these interactions […]

BDNF-TrkB signaling promotes synaptic GluN2A-NMDA receptor expression and network hyperexcitability in cultured hippocampal neurons and during status epilepticus

Posted by dbos Columbia

Endothelial type I interferon signaling modulates the vascular response to ischemic brain injury Kavli Affiliate: Rui Costa | Authors: Pasqualino De Luca, Miranda Mela, Francesca Napoli, Philemon Mshelia, Rui Costa and Carlos B. Duarte | Summary: Brain-derived neurotrophic factor (BDNF) is a key modulator of synaptic function, acting through activation of TrkB receptors. This neurotrophic […]

An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345

Posted by klaurent MIT

Kavli Affiliate: Robert Goeke | Summary:A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Therefore, this potential vital link needs testing by characterising exoplanets around chemically-diverse stars. We present the discovery of two planets orbiting the metal-poor, […]

E-MoFlow: Learning Egomotion and Optical Flow from Event Data via Implicit Regularization

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Wenpu Li, Wenpu Li, , , | Summary: The estimation of optical flow and 6-DoF ego-motion, two fundamental tasks in 3D vision, has typically been addressed independently. For neuromorphic vision (e.g., event cameras), however, the lack of robust data association makes solving the two problems separately an […]
