Polarized muons and the origin of biological homochirality

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

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

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 […]

Monte Carlo simulations of neutrino and charged lepton propagation in the Earth with nuPyProp

Kavli Affiliate: Angela Olinto | First 5 Authors: Sameer Patel, Mary Hall Reno, Yosui Akaike, Luis Anchordoqui, Douglas Bergman | Summary: An accurate modeling of neutrino flux attenuation and the distribution of leptons they produce in transit through the Earth is an essential component to determine neutrino flux sensitivities of underground, sub-orbital and space-based detectors. […]

SNEWPY: A Data Pipeline from Supernova Simulations to Neutrino Signals

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Amanda L. Baxter, Segev BenZvi, Joahan Castaneda Jaimes, Alexis Coleiro, Marta Colomer Molla | Summary: Current neutrino detectors will observe hundreds to thousands of neutrinos from a Galactic supernovae, and future detectors will increase this yield by an order of magnitude or more. With such a data […]

End-to-End Partially Observable Visual Navigation in a Diverse Environment

Kavli Affiliate: Wei Gao | First 5 Authors: Bo Ai, Wei Gao, Vinay, David Hsu, | Summary: How can a robot navigate successfully in a rich and diverse environment, indoors or outdoors, along an office corridor or a trail in the park, on the flat ground, the staircase, or the elevator, etc.? To this end, […]

Imaging reconfigurable molecular concentration on a graphene field-effect transistor

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Franklin Liou, Hsin-Zon Tsai, Andrew S. Aikawa, Kyler C. Natividad, Eric Tang | Summary: The spatial arrangement of adsorbates deposited onto a clean surface in vacuum typically cannot be reversibly tuned. Here we use scanning tunneling microscopy to demonstrate that molecules deposited onto graphene field-effect transistors […]
