Mitosis domain generalization in histopathology images -- The MIDOG challenge
Marc Aubreville, Nikolas Stathonikos, Christof A. Bertram +32
The density of mitotic figures within tumor tissue is known to be highly correlated with tumor proliferation and thus is an important marker in tumor grading. Recognition of mitoti…
Updated Proper Motion of the Neutron Star in the Supernova Remnant Cassiopeia A
Tyler Holland-Ashford, Patrick Slane, Xi Long
In this paper, we present updated estimates of the velocity of the neutron star (NS) in the supernova remnant (SNR) Cassiopeia A using over two decades of Chandra observations. We…
The Proper Motion of the Pulsar J1124-5916 in the Galactic Supernova Remnant G292.0+1.8
Xi Long, Daniel J. Patnaude, Paul P. Plucinsky +1
We present the first direct measurement of the proper motion of pulsar J1124-5916 in the young, oxygen-rich supernova remnant G292.0+1.8. Using deep Chandra ACIS-I observations fro…
XMM-Newton Observations of the High Temperature Plasma in the Large Magellanic Cloud Supernova Remnant N132D
Adam R. Foster, Paul P. Plucinsky, Terrance J. Gaetz +2
We present an analysis of the archival XMM-Newton observations of the Large Magellanic Cloud (LMC) supernova remnant N132D totaling more than 500ks. We focus on the high temperatur…
Reduction of motion artifacts from photoplethysmography signals using learned convolutional sparse coding
Giulio Basso, Xi Long, Reinder Haakma +1
Objective. Wearable devices with embedded photoplethysmography (PPG) enable continuous non-invasive monitoring of cardiac activity, offering a promising strategy to reduce the glob…
Hallucination vs interpretation: rethinking accuracy and precision in AI-assisted data extraction for knowledge synthesis
Xi Long, Christy Boscardin, Lauren A. Maggio +6
Knowledge syntheses (literature reviews) are essential to health professions education (HPE), consolidating findings to advance theory and practice. However, they are labor-intensi…
A Low-latency Pipeline for GRB Light Curve and Spectrum using Fermi/GBM Near Real-time Data
Yi Zhao, Binbin Zhang, Shaolin Xiong +15
Rapid response and short time latency are very important for Time Domain Astronomy, such as the observations of Gamma-ray Bursts (GRBs) and electromagnetic (EM) counterparts of gra…
On the X-ray Properties of the Putative Central Compact Object in 1E 0102.2-7219
Xi Long, Terrance J. Gaetz, Paul P. Plucinsky
We have analyzed the archival Chandra X-ray Observatory observations of the compact feature in the Small Magellanic Cloud supernova remnant (SNR) 1E 0102.2-7219 which has recently…
Characterizing and Detecting Freezing of Gait using Multi-modal Physiological Signals
Ying Wang, Floris Beuving, Jorik Nonnekes +4
Freezing-of-gait a mysterious symptom of Parkinsons disease and defined as a sudden loss of ability to move forward. Common treatments of freezing episodes are currently of moderat…
