Mitigating the Influence of Domain Shift in Skin Lesion Classification: A Benchmark Study of Unsupervised Domain Adaptation Methods on Dermoscopic Images [PDF]
arXiv, 2023 The potential of deep neural networks in skin lesion classification has already been demonstrated to be on-par if not superior to the dermatologists diagnosis. However, the performance of these models usually deteriorates when the test data differs significantly from the training data (i.e. domain shift).

The origin of the two populations of blue stragglers in M30 [PDF]
A&A 621, L10 (2019), 2018 We analyze the position of the two populations of blue stragglers in the globular cluster M30 in the Hertzsprung-Russell diagram. Both populations of blue stragglers are brighter than the cluster's turn-off, but one population (the blue blue-stragglers) align along the zero-age main-sequence whereas the (red) population is elevated in brightness (or ...

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.Summary Background and objectives Technical advances have allowed for significant improvements in imaging techniques in recent years. Specifically, lesions can now be depicted at a much higher magnification – up to 400 x – using optical super‐high magnification dermoscopy (OSHMD).

Acquired bilateral nevus of ota-like macules with Mucosal involvement: A new variant of Hori′s nevus
Indian Journal of Dermatology, 2014 Acquired bilateral nevus of Ota-like macules (ABNOM) or Hori′s nevus, a rare form of acquired dermal melanocytoses, presents as bilateral facial blue-gray macules without ocular or mucosal involvement.

Spitzoid Lesions Diagnosis based on GA feature selection and Random Forest [PDF]
arXiv, 2020 Spitzoid lesions broadly categorized into Spitz Nevus (SN), Atypical Spitz Tumors (AST), and Spitz Melanomas (SM). The accurate diagnosis of these lesions is one of the most challenges for dermapathologists; this is due to the high similarities between them.

Where the Blue Stragglers Roam: Searching for a Link Between Formation and Environment [PDF]
Astrophys.J.661:210-221,2007, 2007 The formation of blue stragglers is still not completely understood, particularly the relationship between formation environment and mechanism. We use a large, homogeneous sample of blue stragglers in the cores of 57 globular clusters to investigate the relationships between blue straggler populations and their environments.

Y12C mutation disrupts IMPDH cytoophidia and alters cancer metabolism
The FEBS Journal, EarlyView.IMPDH, the rate‐limiting enzyme for de novo GTP synthesis, can form polymers and cytoophidia to enhance activity by reducing GTP inhibition. In this study, a Y12C mutation in IMPDH2 was introduced via ABEmax base‐editing in human cancer cell lines to disrupt IMPDH polymerisation.

Random Forests and VGG-NET: An Algorithm for the ISIC 2017 Skin Lesion Classification Challenge [PDF]
arXiv, 2017 This manuscript briefly describes an algorithm developed for the ISIC 2017 Skin Lesion Classification Competition. In this task, participants are asked to complete two independent binary image classification tasks that involve three unique diagnoses of skin lesions (melanoma, nevus, and seborrheic keratosis).

Histopathology, EarlyView.Here we report the features of 24 BAP1‐inactivated melanocytic tumours including 19 BAP1‐inactivated melanocytomas (BIMs) and five BAP1‐inactivated melanomas. BIMs have a favourable prognosis, even those with multiple copy number aberrations (CNAs).

Nevus of Ota with Rare Palatal Involvement: A Case Report with Emphasis on Differential Diagnosis
Case Reports in Dentistry, 2011 Nevus of Ota, a dermal melanocytic nevus, is rare in the Indian subcontinent. It presents as a brown, blue, or gray patch on the face and is within the distribution of the ophthalmic and maxillary branches of the trigeminal nerve.
