Librational Feedback Cooling

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Charles P. Blakemore, Denzal Martin, Alexander Fieguth, Nadav Priel, Gautam Venugopalan | Summary: Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the cooling of one librational degree of freedom for $sim 5~mu$m […]

Accretion Variability as a Guide to Stellar Mass Assembly

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: William J. Fischer, Lynne A. Hillenbrand, Gregory J. Herczeg, Doug Johnstone, Ágnes Kóspál | Summary: Variable accretion in young stellar objects reveals itself photometrically and spectroscopically over a continuum of timescales and amplitudes. Most dramatic are the large outbursts (e.g., FU Ori, V1647 Ori, and EX […]

Active control of thermal emission by graphene-nanowire coupled plasmonic metasurfaces

Kavli Affiliate: Zhuo Li | First 5 Authors: Jiayu Li, Zhuo Li, Xiu Liu, Stanislav Maslovski, Sheng Shen | Summary: Metasurfaces, together with graphene plasmonics, have become prominent for the emissivity control in thermal engineering, both passively through changing the geometric parameters and packing density of the metasurfaces, and actively through graphene gating or doping. […]

Delving into the Estimation Shift of Batch Normalization in a Network

Kavli Affiliate: Yi Zhou | First 5 Authors: Lei Huang, Yi Zhou, Tian Wang, Jie Luo, Xianglong Liu | Summary: Batch normalization (BN) is a milestone technique in deep learning. It normalizes the activation using mini-batch statistics during training but the estimated population statistics during inference. This paper focuses on investigating the estimation of population […]
