Quantum criticality of fermion velocities and critical temperature nearby a putative quantum phase transition in the $d$-wave superconductors

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Xiao-Yue Ren, Ya-Hui Zhai, Jing Wang, , | Summary: Quantum critical behaviors induced by a putative quantum phase transition are vigilantly investigated, which separates a $d$-wave superconducting state and $d$-wave superconducting+$X$ state below the superconducting dome of the $d-$wave superconductors with tuning the non-thermal doping variable. Within […]

Assisted Learning for Organizations with Limited Data

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Cheng Chen, Jiaying Zhou, Jie Ding, Yi Zhou, | Summary: We develop an assisted learning framework for assisting organization-level learners to improve their learning performance with limited and imbalanced data. In particular, learners at the organization level usually have sufficient computation resource, but are subject to stringent […]

Dark matter constraints with stacked gamma rays scales with the number of galaxies

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, Oscar Macias, | Summary: Low-surface-brightness galaxies (LSBGs) are interesting targets for searches of dark matter emission due to their low baryonic content. However, predicting their expected dark matter emissivities is difficult because of observational challenges in their distance measurements. Here […]

Dark matter constraint with gamma-ray galaxies cross correlation scales with N

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, Oscar Macias, | Summary: A new method to constrain the dark matter annihilation cross section by taking the cross correlation of gamma-ray diffuse maps and galaxies is proposed. As a result, the statistical power of constraining the annihilation cross section […]

Polarized muons and the origin of biological homochirality

Posted by klaurent Stanford

Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Roger D. Blandford, Anatoli Fedynitch, , | Summary: While biologists have not yet reached a consensus on the definition of life, homochirality – the specific molecular handedness of biomolecules – is a phenomenon only produced by life. The unraveling of its origin requires interdisciplinary […]

DeepGhostBusters: Using Mask R-CNN to Detect and Mask Ghosting and Scattered-Light Artifacts from Optical Survey Images

Posted by klaurent Chicago

Kavli Affiliate: Brian Nord | First 5 Authors: Dimitrios Tanoglidis, Aleksandra Ćiprijanović, Alex Drlica-Wagner, Brian Nord, Michael H. L. S. Wang | Summary: Wide-field astronomical surveys are often affected by the presence of undesirable reflections (often known as "ghosting artifacts" or "ghosts") and scattered-light artifacts. The identification and mitigation of these artifacts is important for […]

Subtle Data Crimes: Naively training machine learning algorithms could lead to overly-optimistic results

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Efrat Shimron, Jonathan I. Tamir, Ke Wang, Michael Lustig, | Summary: While open databases are an important resource in the Deep Learning (DL) era, they are sometimes used "off-label": data published for one task are used for training algorithms for a different one. This work aims to […]
