Lesion Border Detection in Dermoscopy Images Using Ensembles of Thresholding Methods
M. Emre Celebi, Quan Wen, Sae Hwang +2
Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation…
A Closer Look at the Fluctuations in Brightness of SN 2009ip During Its Late 2012 Eruption
John C. Martin, Franz-Josef Hambsch, Raffaella Margutti +3
The supernova impostor SN 2009ip has re-brightened several times since its initial discovery in August 2009. During its last outburst in late September 2012 it reached a peak brigh…
Liouville Type Property and Spreading Speeds of KPP Equations in Periodic Media with Localized Spatial Inhomogeneity
Liang Kong, Wenxian Shen
The current paper is devoted to the study of semilinear dispersal evolution equations of the form wher…
A panchromatic view of the restless SN2009ip reveals the explosive ejection of a massive star envelope
R. Margutti, D. Milisavljevic, A. M. Soderberg +54
The 2012 explosion of SN2009ip raises questions about our understanding of the late stages of massive star evolution. Here we present a comprehensive study of SN2009ip during its r…
Luminous and Variable Stars in M31 and M33. I. The Warm Hypergiants and Post-Red Supergiant Evolution
Roberta M. Humphreys, Kris Davidson, Skyler Grammer +4
The progenitors of Type IIP supernovae have an apparent upper limit to their initial masses of about 20 solar masses, suggesting that the most massive red supergiants evolve to war…
The 2011 Periastron Passage of the Be Binary delta Scorpii
A. S. Miroshnichenko, A. V. Pasechnik, N. Manset +19
We describe the results of the world-wide observing campaign of the highly eccentric Be binary system delta Scorpii 2011 periastron passage which involved professional and amateur…
