Kavli Affiliate: George Efstathiou | First 5 Authors: Jiten Dhandha, Jiten Dhandha, , , | Summary: The cosmic 21-cm signal is a promising probe of the early Universe, owing to its sensitivity to the thermal state of the neutral intergalactic medium (IGM) and properties of the first luminous sources. In this work, we constrain the […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: , , , , | Summary: Broad absorption line (BAL) quasars are often considered X-ray weak relative to their optical/UV luminosity, whether intrinsically (i.e., the coronal emission is fainter) or due to large column densities of absorbing material. The SDSS-V is providing optical spectroscopy for samples of […]
Kavli Affiliate: Long Zhang | First 5 Authors: Yin Yang, Yin Yang, , , | Summary: We develop a quantum algorithm for linear algebraic equations Ax=b from the perspective of Schr"odingerization-form problems, which are characterized by a system of linear convection equations in one higher dimension. When A is positive definite, the solution x can […]
Kavli Affiliate: Leon Balents | First 5 Authors: Tarun Advaith Kumar, Tarun Advaith Kumar, , , | Summary: A variety of generative neural networks recently adopted from machine learning have provided promising strategies for studying quantum matter. In particular, the success of autoregressive models in natural language processing has motivated their use as variational ans"atze, […]
Kavli Affiliate: Jia Liu | First 5 Authors: Hao Zhao, Hao Zhao, , , | Summary: Estimating neuron location from extracellular recordings is essential for developing advanced brain-machine interfaces. Accurate neuron localization improves spike sorting, which involves detecting action potentials and assigning them to individual neurons. It also helps monitor probe drift, which affects long-term […]
Kavli Affiliate: Feng Wang | First 5 Authors: Hao Fang, Hao Fang, , , | Summary: Live streaming has experienced significant growth recently. Yet this rise in popularity contrasts with the reality that a substantial segment of the global population still lacks Internet access. The emergence of Low Earth orbit Satellite Networks (LSNs), such as […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeeshan Ahmed, Zeeshan Ahmed, , , | Summary: This paper tackles several challenges that arise when integrating Automatic Speech Recognition (ASR) and Machine Translation (MT) for real-time, on-device streaming speech translation. Although state-of-the-art ASR systems based on Recurrent Neural Network Transducers (RNN-T) can perform real-time transcription, achieving […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Jinhui Guo, , , | Summary: We propose and study a purely inelastic scalar dark matter model, where two real scalars-dark matter $phi_1$ and its excited partner $phi_2$ interact with the Standard Model via a Higgs portal. After mass diagonalization, only inelastic couplings remain, allowing […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Pau Amaro Seoane, , , | Summary: The existence of curvature singularities and the information and firewall paradoxes are significant problems for the conventional black hole model. The black mirror hypothesis provides a CPT-symmetric alternative to the classical description of black hole, offering […]
Kavli Affiliate: Robert L. Byer | First 5 Authors: Jakob M. Grzesik, Jakob M. Grzesik, , , | Summary: Scattering experiments with energetic particles, such as free electrons, have been historically used to reveal the quantum structure of matter. However, realizing coherent interactions between free-electron beams and solid-state quantum systems has remained out of reach, […]
