Superposition- and interference-induced optical spectrum distortion in the figure-9 fiber laser

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Guochao Wang, Kangrui Chang, Haobin Zheng, Yongzhuang Zhou | Summary: The spectrum of the output pulses from the figure-9 laser typically exhibits more distortion than the spectra from mode-locked lasers based on other saturable absorbers and the spectrum of its intracavity pulses. Here, we demonstrate […]

Evidence for a shock-compressed magnetic field in the northwestern rim of Vela Jr. from X-ray polarimetry

Kavli Affiliate: Nicola Omodei | First 5 Authors: Dmitry A. Prokhorov, Yi-Jung Yang, Riccardo Ferrazzoli, Jacco Vink, Patrick Slane | Summary: Synchrotron X-ray emission has been detected from nearly a dozen young supernova remnants (SNRs). X-rays of synchrotron origin exhibit linear polarization in a regular, non-randomly oriented magnetic field. The significant polarized X-ray emission from […]

A simple accurate way to model noise-seeded ultrafast nonlinear processes

Kavli Affiliate: Frank Wise | First 5 Authors: Yi-Hao Chen, Frank Wise, , , | Summary: Noise can play an important role in nonlinear pulse propagation. It is not only the origin of fluctuations in supercontinuum but can also determine the generated signal amplitude and phase, as seen in phenomena such as noise-seeded four-wave mixing […]

Drosophila Trus, the orthologue of mammalian PDCD2L, is required for proper cell proliferation, larval developmental timing, and oogenesis

Kavli Affiliate: Michael Goldberg | Authors: Saeko Takada, Bonnie J. Bolkan, MaryJane O’Connor, Michael Goldberg and Michael B. O’Connor | Summary: Toys are us (Trus) is the Drosophila ortholog of mammalian Programmed Cell Death 2-Like (PDCD2L), a protein that has been implicated in ribosome biogenesis, cell cycle regulation, and oncogenesis. In this study, we examined […]

Encoding manifolds constructed from grating responses organize responses to natural scenes in cortical visual areas

Kavli Affiliate: Michael Stryker | Authors: Luciano Dyballa, Greg D Field, Michael P Stryker and Steven W Zucker | Summary: We have created “encoding manifolds” to reveal the overall responses of a brain area to a variety of stimuli. Encoding manifolds organize response properties globally: each point on an encoding manifold is a neuron, and […]

Improving Galaxy Cluster Selection with the Outskirt Stellar Mass of Galaxies

Kavli Affiliate: Eli Rykoff | First 5 Authors: Matthew Kwiecien, Tesla Jeltema, Alexie Leauthaud, Song Huang, Eli Rykoff | Summary: The number density and redshift evolution of optically selected galaxy clusters offer an independent measurement of the amplitude of matter fluctuations, $S_8$. However, recent results have shown that clusters chosen by the redMaPPer algorithm show […]

A Two-Week $IXPE$ Monitoring Campaign on Mrk 421

Kavli Affiliate: Nicola Omodei | First 5 Authors: W. Peter Maksym, Ioannis Liodakis, M. Lynne Saade, Dawoon E. Kim, Riccardo Middei | Summary: X-ray polarization is a unique new probe of the particle acceleration in astrophysical jets made possible through the Imaging X-ray Polarimetry Explorer. Here we report on the first dense X-ray polarization monitoring […]

Counting Ability of Large Language Models and Impact of Tokenization

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Juntai Cao, Chenyu You, , | Summary: Transformers, the backbone of modern large language models (LLMs), face inherent architectural limitations that impede their reasoning capabilities. Unlike recurrent networks, Transformers lack recurrent connections, confining them to constant-depth computation. This restriction places them in the complexity class […]
