Developmental spontaneous activity promotes sensory domains, frequency tuning and proper gain in central auditory circuits

Posted by klaurent Hopkins

Kavli Affiliate: Dwight Bergles | Authors: Calvin J Kersbergen, Travis A Babola, Jason Rock and Dwight E Bergles | Summary: Neurons that process sensory information exhibit bursts of electrical activity during development, providing early training to circuits that will later encode similar features of the external world. In the mammalian auditory system, this intrinsically generated […]

Hard X-ray emission from the eastern jet of SS 433 powering the W50 `Manatee’ nebula: Evidence for particle re-acceleration

Posted by klaurent MIT

Kavli Affiliate: Melania Nynka | Summary:We present a broadband X-ray study of W50 (`the Manatee nebula’), the complex region powered by the microquasar SS 433, that provides a test-bed for several important astrophysical processes. The W50 nebula, a Galactic PeVatron candidate, is classified as a supernova remnant but has an unusual double-lobed morphology likely associated […]

Learning to correct spectral methods for simulating turbulent flows

Posted by klaurent Harvard

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Gideon Dresdner, Dmitrii Kochkov, Peter Norgaard, Leonardo Zepeda-Núñez, Jamie A. Smith | Summary: Despite their ubiquity throughout science and engineering, only a handful of partial differential equations (PDEs) have analytical, or closed-form solutions. This motivates a vast amount of classical work on numerical simulation of PDEs […]

Search for a dark photon and an invisible dark Higgs boson in $μ^+μ^-$ and missing energy final states with the Belle II experiment

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, L. Aggarwal, H. Aihara | Summary: The dark photon $A^prime$ and the dark Higgs boson $h^prime$ are hypothetical particles predicted in many dark sector models. We search for the simultaneous production of $A^prime$ and $h^prime$ in the dark Higgsstrahlung process […]

Poisson brackets in Sobolev spaces: a mock holonomy-flux algebra

Posted by klaurent MIT

Kavli Affiliate: J. S. Villasenor | Summary:The purpose of this paper is to discuss a number of issues that crop up in the computation of Poisson brackets in field theories. This is specially important for the canonical approaches to quantization and, in particular, for loop quantum gravity. We illustrate the main points by working out […]

WS-Snapshot: An effective algorithm for wide-field and large-scale imaging

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yangfan Xie, Feng Wang, Hui Deng, Ying Mei, Ying-He Celeste Lu | Summary: The Square Kilometre Array (SKA) is the largest radio interferometer under construction in the world. The high accuracy, wide-field and large size imaging significantly challenge the construction of the Science Data Processor (SDP) of […]

Reading and Writing: Discriminative and Generative Modeling for Self-Supervised Text Recognition

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Mingkun Yang, Minghui Liao, Pu Lu, Jing Wang, Shenggao Zhu | Summary: Existing text recognition methods usually need large-scale training data. Most of them rely on synthetic training data due to the lack of annotated real images. However, there is a domain gap between the synthetic data […]
