Dysregulation of astrocyte-secreted pleiotrophin contributes to neuronal structural and functional phenotypes in Down Syndrome

Posted by klaurent UCSD / Salk

Kavli Affiliate: Nicola Allen | Authors: Ashley N Brandebura, Quinn N Asbell, Mariel Kristine B Micael and Nicola J Allen | Summary: Neuronal dendrite structure and synapse formation is tightly regulated during development to promote proper connectivity. Astrocyte-secreted proteins act as guidance and pro-synaptogenic factors, and astrocyte protein secretion is dysregulated in neurodevelopmental disorders with […]

Small-scale signatures of primordial non-Gaussianity in k-Nearest Neighbour cumulative distribution functions

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: William R. Coulton, Tom Abel, Arka Banerjee, , | Summary: Searches for primordial non-Gaussianity in cosmological perturbations are a key means of revealing novel primordial physics. However, robustly extracting signatures of primordial non-Gaussianity from non-linear scales of the late-time Universe is an open problem. In this paper, […]

Perfect Coulomb drag in a dipolar excitonic insulator

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Liguo Ma, Raghav Chaturvedi, Kenji Watanabe, Takashi Taniguchi | Summary: Excitonic insulators (EIs), arising in semiconductors when the electron-hole binding energy exceeds the band gap, are a solid-state prototype for bosonic phases of matter. Unlike the charged excitations that are frozen and unable to […]

Manifestly covariant variational principle for gauge theories of gravity

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, Will Barker, , | Summary: A variational principle for gauge theories of gravity is presented, which maintains manifest covariance under the symmetries to which the action is invariant, throughout the calculation of the equations of motion and conservation laws. This is performed by […]

Clump-scale Gas Infall in High-mass Star Formation: a Multi-transition View with JCMT HCN (4–3) Mapping

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Yuxin He, Jingwen Wu, Lei Zhu | Summary: Gas infall motions play a crucial role in high-mass star formation and are characterized by observable signatures in the form of blue-shifted asymmetric spectral line profiles ("blue profiles"). However, the connection between blue profiles and […]

Multiferroic Magnon Spin-Torque Based Reconfigurable Logic-In-Memory

Posted by klaurent Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Yahong Chai, Yuhan Liang, Cancheng Xiao, Yue Wang, Bo Li | Summary: Magnons, bosonic quasiparticles carrying angular momentum, can flow through insulators for information transmission with minimal power dissipation. However, it remains challenging to develop a magnon-based logic due to the lack of efficient electrical manipulation […]
