Kavli Affiliate: Patrick Kanold | Authors: Ji Liu and Patrick O Kanold | Summary: SUMMARY Predictive coding theory postulates that the brain achieves perception by actively making predictions about the incoming sensory information and correcting them if errors signals arise. These signals are likely the most relevant when the individual is actively interacting with the […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Sheng Wang, Yi Zhou, , , | Summary: In this article, we prove the global well-posedness in the critical Sobolev space $H_{rad}^2left(mathbb{R}^2right) times H_{rad}^1 left(mathbb{R}^2right)$ for the radial time-like extremal hypersurface equation in $left(1+3right)$- dimensional Minkowski space-time. This is achieved by deriving a new div-curl type lemma […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Arkadev Roy, Luis Ledezma, Luis Costa, Robert Gray, Ryoto Sekine | Summary: Optical frequency comb is an enabling technology for a multitude of applications from metrology to ranging and communications. The tremendous progress in sources of optical frequency combs has mostly been centered around the near-infrared spectral […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Yanan Wang, Ranieri D. Baldi, Santiago del Palacio, Muryel Guolo, Xiaolong Yang | Summary: AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and the infrared […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Ulrich Sperhake, Thomas Helfer, Robin Croft, Miren Radia | Summary: We present a generalization of the curative initial data construction derived for equal-mass compact binaries in Helfer {it et al} (2019 Phys. Rev. D 99 044046; 2022 Class. Quantum Grav. 39 074001) to arbitrary mass […]
Kavli Affiliate: Timothy A. Ryan | Authors: Mukesh Kumar, Justin Knapp, Kallol Gupta and Timothy A Ryan | Summary: Recent advances have expanded the role of lipid droplets (LDs) beyond passive lipid storage, implicating their involvement in various metabolic processes across mammalian tissues. Neuronal LDs, long debated in existence, have been identified in several neural […]
Kavli Affiliate: Gary A. Steele | First 5 Authors: Ines C. Rodrigues, Gary A. Steele, Daniel Bothner, , | Summary: Harmonic oscillators belong to the most fundamental concepts in physics and are central to many current research fields such as circuit QED, cavity optomechanics and photon-pressure systems. Here, we engineer an effective negative mass harmonic […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao, Risa H. Wechsler, Marla Geha | Summary: We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method. Our selection consists of a […]
Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Yukta Ajay, Muryel Guolo, Dheeraj Pasham, , | Summary: We present multiwavelength analyses of an active optical transient AT2021fxu which shows the appearance of previously absent broad emission lines in a recent optical spectrum, suggesting a Changing-look (CL) Active Galactic Nucleus (AGN). During the spectral transition, the […]
