Semi-supervised Symmetric Non-negative Matrix Factorization with Low-Rank Tensor Representation

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Yuheng Jia, Jia-Nan Li, Wenhui Wu, Ran Wang, | Summary: Semi-supervised symmetric non-negative matrix factorization (SNMF) utilizes the available supervisory information (usually in the form of pairwise constraints) to improve the clustering ability of SNMF. The previous methods introduce the pairwise constraints from the local perspective, i.e., […]

Merging gas-rich galaxies that harbor low-luminosity twin quasars at z = 6.05: a promising progenitor of the most luminous quasars

Posted by dbos Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Takuma Izumi, Yoshiki Matsuoka, Masafusa Onoue, Michael A. Strauss, Hideki Umehata | Summary: We present ALMA [CII] 158 $mu$m line and underlying far-infrared (FIR) continuum emission observations ($0”.57 times 0”.46$ resolution) toward a quasar-quasar pair system recently discovered at $z = 6.05$ (Matsuoka et al. 2024). […]

Two routes to value-based decisions in Parkinsons disease: differentiating incremental reinforcement learning from episodic memory

Posted by dbos Columbia

Kavli Affiliate: Daphna Shohamy | Authors: Peter Jendrichovsky, Hey-Kyoung Lee and Patrick O Kanold | Summary: Patients with Parkinsons disease are impaired at incremental reward-based learning. It is typically assumed that this impairment reflects a loss of striatal dopamine. However, many open questions remain about the nature of reward-based learning deficits in Parkinsons. Recent studies […]

Dark exposure reduces high-frequency hearing loss in C57BL/6J mice

Posted by dbos Hopkins

Kavli Affiliate: Hey-Kyoung Lee and Patrick Kanold | Authors: Peter Jendrichovsky, Hey-Kyoung Lee and Patrick O Kanold | Summary: Plastic changes in the brain are primarily limited to early postnatal periods. Recovery of adult brain plasticity is critical for the effective development of therapies. A brief (1-2 week) duration of visual deprivation (dark exposure, DE) […]

Gravothermal Catastrophe in Resonant Self-interacting Dark Matter Models

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Daniel Gilman, Mark Vogelsberger, Xuejian Shen, Stephanie O’Neil | Summary: We investigate a self-interacting dark matter (SIDM) model featuring a velocity-dependent cross section with an order-of-magnitude resonant enhancement of the cross section at $sim 16,{rm km},{rm s}^{-1}$. To understand the implications for the structure of […]

A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel | Summary:The last few years have seen the emergence of a wide array of novel techniques for analyzing high-precision data from upcoming galaxy surveys, which aim to extend the statistical analysis of galaxy clustering data beyond the linear regime and the canonical two-point (2pt) statistics. We test and benchmark some of […]
