Overexpression of Meis factors in late-stage retinal progenitors yields complex effects on temporal patterning and neurogenesis.

Kavli Affiliate: Seth Blackshaw | Authors: Patrick Leavey, Lizhi Jiang, Nicole Pannullo, Clayton Santiago and Seth Blackshaw | Summary: The vertebrate retina serves as a model for studying neurogenesis and cell fate specification, with retinal progenitor cells following a tightly regulated temporal sequence to generate distinct cell types. Meis1 and Meis2 are transcription factors implicated […]

A XRISM Observation of the Archetypal Radio-Mode Feedback System Hydra-A: Measurements of Atmospheric Motion and Constraints on Turbulent Dissipation

Kavli Affiliate: Michael McDonald | Summary:We present XRISM Resolve observations centered on Hydra-A, a redshift z = 0.054 brightest cluster galaxy which hosts one of the largest and most powerful FR-I radio sources in the nearby Universe. We examine the effects of its high jet power on the velocity structure of the cluster’s hot atmosphere. […]

Entanglement Maximization and Mirror Symmetry in Two-Higgs-Doublet Models

Kavli Affiliate: Marcela Carena | Summary:We consider 2-to-2 scatterings of Higgs bosons in a CP-conserving two-Higgs-doublet model (2HDM) and study the implication of maximizing the entanglement in the flavor space, where the two doublets $Φ_a$, $a=1,2$, can be viewed as a qubit: $Φ_1=|0rangle$ and $Φ_2=|1rangle$. More specifically, we compute the scattering amplitudes for $Φ_a Φ_b […]
