GLIMPSE: An ultra-faint $simeq$ 10$^{5}$ $M_{odot}$ Pop III Galaxy Candidate and First Constraints on the Pop III UV Luminosity Function at $zsimeq6-7$

Posted by dbos January 20, 2025MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Seiji Fujimoto, Rohan P. Naidu, John Chisholm, Hakim Atek, Ryan Endsley | Summary: Detecting the first generation of stars, Population III (PopIII), has been a long-standing goal in astrophysics, yet they remain elusive even in the JWST era. Here we present a novel NIRCam-based selection method for […]

Imaging signatures of edge currents in a magnetic topological insulator

Posted by dbos January 20, 2025February 5, 2025Cornell

Kavli Affiliate: Katja C. Nowack | First 5 Authors: G. M. Ferguson, Run Xiao, Anthony R. Richardella, Austin Kaczmarek, Nitin Samarth | Summary: Magnetic topological insulators (MTIs) host topologically protected edge states, but the role that these edge states play in electronic transport remains unclear. Using scanning superconducting quantum interference device (SQUID) microscopy, we performed […]

Localized stem structures in quasi-resonant solutions of the Kadomtsev-Petviashvili equation

Posted by dbos January 20, 2025Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Jingsong He, Yi Cheng, , | Summary: When the phase shift of X-shaped solutions before and after interaction is finite but approaches infinity, the vertices of the two V-shaped structures become separated due to the phase shift and are connected by a localized structure. This […]

Localized stem structures in soliton reconnection of the asymmetric Nizhnik-Novikov-Veselov system

Posted by dbos January 20, 2025Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Jingsong He, Yi Cheng, , | Summary: The reconnection processes of 3-solitons with 2-resonance can produce distinct local structures that initially connect two pairs of V-shaped branches, then disappear, and later re-emerge as new forms. We call such local structures as stem structures. In this […]

The effects of task similarity during representation learning in brains and neural networks

Posted by dbos January 20, 2025January 30, 2025Columbia

Kavli Affiliate: Stefano Fusi | Authors: Nicholas Menghi, William Jeffrey Johnston, Simone Vigano’, Max Andreas Bosse Hinrichs, Burkhard Maess, Stefano Fusi and Christian F Doeller | Summary: The complexity of our environment poses significant challenges for adaptive behavior. Recognizing shared structures across tasks can theoretically improve learning through generalization. However, how such shared representations emerge […]

Energy-Efficient Ultrashort-Pulse Characterization using Nanophotonic Parametric Amplification

Posted by January 19, 2025Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Thomas Zacharias, Robert Gray, Ryoto Sekine, James Williams, Selina Zhou | Summary: The growth of ultrafast nanophotonic circuits necessitates the development of energy-efficient on-chip pulse characterization techniques. Nanophotonic realizations of Frequency Resolved Optical Gating, a common pulse characterization technique in bulk optics, have been challenging due to […]

The energy dependence of cluster size and its physical processes in the proton measurement with TimePix3 silicon detector

Posted by dbos January 19, 2025Tokyo

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Naoki Itoh, Hugo Allaire, Tokihiro Ikeda, Shunsaku Nagasawa, Shinji Okada | Summary: We investigated the energy dependence of the number of triggered pixels, or cluster size, when charged particles are detected using the TimePix3 detector with a silicon sensor. We measured protons in the range of 1.5~3.3 […]

MetaLigand: A database for predicting non-peptide ligand mediated cell-cell communication

Posted by dbos January 19, 2025January 30, 2025Hopkins

Kavli Affiliate: Richard Axel | Authors: Andrew Jacob Pixley Fink, Samuel Muscinelli, Shuqi Wang, Marcus I Hogan, Daniel Fine English, Richard Axel, Ashok Litwin-Kumar and Carl E. Schoonover | Summary: Non-peptide ligands (NPLs), including lipids, amino acids, carbohydrates, and non-peptide neurotransmitters and hormones, play a critical role in ligand-receptor-mediated cell-cell communication, driving diverse physiological and […]
