Optical Refrigeration for an Optomechanical Amplifier

Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Samuel Schulz, Yehonathan Drori, Christopher Wipf, Rana X Adhikari, | Summary: We explore the viability of using optical refrigeration as a low-vibration cooling method for a phase-sensitive optomechanical amplifier proposed to improve the sensitivity of future gravitational wave detectors. We find that with moderate improvements on […]

A New Component from the Quiet Sun: Synchrotron Radiation from Galactic Cosmic-Ray Electrons

Kavli Affiliate: Vahe Petrosian | First 5 Authors: , , , , | Summary: The quiet Sun, i.e. in its non-flaring state or non-flaring regions, emits thermal radiation from radio to ultraviolet. The quiet Sun produces also non-thermal radiation observed in gamma rays due to interactions of Galactic Cosmic Rays (GCR) with the solar gas […]

Transport of Cosmic ray electrons from 1 AU to the Sun

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Vahe’ Petrosian, Elena Orlando, Andrew Strong, , | Summary: Gamma rays are produced by cosmic ray (CR) protons interacting with the particles at solar photosphere and by cosmic ray electrons and positrons (CRes) via inverse Compton scattering of solar photons. The former come from the solar disk […]

Automated head-fixation training system with high levels of animal participation in psychoacoustic tasks

Kavli Affiliate: Patrick Kanold | Authors: Ji Liu, Kate Maximov and Patrick O Kanold | Summary: Abstract Many animal training paradigms rely on head-fixation. Head-fixation training is typically laborious and can benefit from automation to relieve the workload as well as to reduce the variability in the training outcome. Several groups have reported successful implementations […]

A selectivity filter in the EMC limits protein mislocalization to the ER

Kavli Affiliate: Vy Thuy Nguyen | Authors: Tino Pleiner, Masami Hazu, Giovani Pinton Tomaleri, Vy N. Nguyen, Kurt Januszyk and Rebecca M. Voorhees | Summary: SUMMARY Tail anchored proteins (TAs) play essential roles at both the ER and mitochondria, and their accurate localization is critical to proteostasis. Biophysical similarities lead to mistargeting of mitochondrial TAs […]

Spatiotemporal control of active topological defects

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Suraj Shankar, Luca V. D. Scharrer, Mark J. Bowick, M. Cristina Marchetti, | Summary: Topological defects play a central role in the physics of many materials, including magnets, superconductors and liquid crystals. In active fluids, defects become autonomous particles that spontaneously propel from internal active stresses […]
