Genome Organization with CUT and Tag (GO-CaT) identifies substructure and maturation of lamina-associated domains in neurons of the developing human brain

Kavli Affiliate: Arnold R. Kriegstein | Authors: Chujing Zhang, Eugene Gil, Sajad Hamid Ahanger, Mingcong Li, Li Wang, Jingjing Li, Arnold Kriegstein and Daniel Lim | Summary: Approximately 30-40% of the human genome is anchored to the nuclear lamina through variably sized (10 kb–10 Mb) lamina-associated domains (LADs). Previous work in cultured murine and human […]

Signatures of black hole seeding in the local Universe: Predictions from the BRAHMA cosmological simulations

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K Bhowmick, Laura Blecha, Paul Torrey, Rachel S Somerville, Luke Zoltan Kelley | Summary: The first "seeds" of supermassive black holes (BHs) continue to be an outstanding puzzle, and it is currently unclear whether the imprints of early seed formation survive today. Here we examine the […]

Rapid Rotation of Polarization Orientations in PSR B1919+21’s Single Pulses: Implications On Pulsar’s Magnetospheric Dynamics

Kavli Affiliate: Kejia Lee | First 5 Authors: Shunshun Cao, Jinchen Jiang, Jaroslaw Dyks, Kejia Lee, Jiguang Lu | Summary: We analyse and model rapid rotations of polarization orientations in PSR B1919+21’s single pulses, based on FAST observation data. In more than one third of B1919+21’s single pulses, polarization angle (PA) is found to rotate […]

A Short-lived Rejuvenation during the Decades-long Changing-look Transition in the Nucleus of Mrk 1018

Kavli Affiliate: Luis C. Ho | First 5 Authors: Kai-Xing Lu, Yan-Rong Li, Qingwen Wu, Luis C. Ho, Zhi-Xiang Zhang | Summary: Changing-look active galactic nuclei (CL-AGNs), characterized by emerging or disappearing of broad lines accompanied with extreme continuum flux variability, have drawn much attention for their potential of revealing physical processes underlying AGN evolution. […]

Supervised Learning-enhanced Multi-Group Actor Critic for Live Stream Allocation in Feed

Kavli Affiliate: Li Xin Li | First 5 Authors: Jingxin Liu, Xiang Gao, Yisha Li, Xin Li, Haiyang Lu | Summary: In the context of a short video & live stream mixed recommendation scenario, the live stream recommendation system (RS) decides whether to allocate at most one live stream into the video feed for each […]

A Trade-Off Between Path Entanglement and Quantum Sensitivity

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Benjamin Lou, Hudson A. Loughlin, Nergis Mavalvala, , | Summary: Entanglement often increases quantum measurement schemes’ sensitivity. However, we find that in precision measurements with zero-mean Gaussian states, such as squeezed states, entanglement between different paths degrades measurement sensitivity. We prove an inverse relationship between entanglement entropy […]
