, 2018 Training of neural networks for automated diagnosis of pigmented skin lesions is hampered by the small size and lack of diversity of available datasets of dermatoscopic images. We tackle this problem by releasing the HAM10000 ("Human Against Machine with

Can Deep Learning Assist Automatic Identification of Layered Pigments From XRF Data? [PDF]
arXiv, 2022 X-ray fluorescence spectroscopy (XRF) plays an important role for elemental analysis in a wide range of scientific fields, especially in cultural heritage. XRF imaging, which uses a raster scan to acquire spectra across artworks, provides the opportunity for spatial analysis of pigment distributions based on their elemental composition.

Optical Coherence Tomography Angiography of Iris Nevus: A Case Report [PDF]
, 2016 Iris nevus is common: 6% of patients with suspected iris melanoma have lesions other than melanoma, and 36% of them are nevi. Iris nevus turns into melanoma in approximately 8% of cases at a mean of 15 years.

Giant congenital melanocytic nevus with neurofibroma-like lesions and onset of vitiligo
Journal of Dermatology and Dermatologic Surgery, 2015 Giant congenital pigmented nevus and neurofibromatosis type 1 may rarely occur together. We reported here an unusual case where giant congenital melanocytic nevus was associated with neurofibroma-like lesions and vitiligo, emphasizing the clinical and ...

Efficient structural color from pigment-loaded nanostructures [PDF]
arXiv, 2023 Color can originate from wavelength-dependence in the absorption of pigments or the scattering of nanostructures. While synthetic colors are dominated by the former, vivid structural colors found in nature have inspired much research on the latter. However, many of the most vibrant colors in nature involve the interactions of structure and pigment ...

bioRxiv, 2020 Mutational activation of the BRAF proto-oncogene in melanocytes reliably produces benign nevi (pigmented “moles”), yet the same change is the most common driver mutation in melanoma.

Synthesis and acid resistance of maya blue pigment [PDF]
Archaeometry 48, 1 (2006) 115-130, 2012 Maya blue is an organo-clay artificial pigment composed of indigo and palygorskite. It was invented and frequently used in Mesoamerica in ancient times (eighth to 16th centuries). We analyse in this paper one of the characteristics of Maya blue that has attracted the attention of scientists since its rediscovery in 1931: its high stability against ...

Rosette‐like structures in the spectrum of spitzoid tumors [PDF]
, 2013 Background Spitz nevi demonstrate a diverse spectrum of morphologies. Recently, there have been two reported examples of Spitz nevi with rosette‐like structures similar to Homer‐Wright rosettes.
