Graph-based Learning Networks for Automatic Pigment Mapping of Historical Artifacts [PDF]

, 2023
Hyperspectral image classification can be a difficult task due to a lack of ground-truth labels and spectral variability. For hyperspectral images (HSIs) of historical artifacts, which are generally man-made objects, this is generally a significant ...

Unmixing and pigment identification using visible and short-wavelength infrared: Reflectance vs logarithm reflectance hyperspaces [PDF]

, 2023
Hyperspectral imaging has recently consolidated as a useful technique for pigment mapping and identification, although it is commonly supported by additional non-invasive analytical methods.

Morphological and elemental mapping of gallstones using synchrotron microtomography and synchrotron X‐ray fluorescence spectroscopy

JGH Open, 2019
Background and Aim Regional differences in gallstone (GS) composition are well documented in the Indian subcontinent. The reasons for the same are unknown. Etiopathogenesis of GS remains elusive despite advances in instrumentation.

An SNP-based second-generation genetic map of Daphnia magna and its application to QTL analysis of phenotypic traits [PDF]

, 2014
Background: Although Daphnia is increasingly recognized as a model for ecological genomics and biomedical research, there is, as of yet, no high-resolution genetic map for the genus.

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Effect of mineralizer on the synthesis of (Ni, Mn) co-doping CuFe5O8 pigment and its glazing performance

Open Ceramics
Novel Co and Cr free, high-temperature (Ni, Mn) co-doping CuFe5O8 black ceramic pigments were synthesized. The effects of mineralizer type and mineralizer amount on the synthesis and coloration of (Ni, Mn) co-doping CuFe5O8 pigments, as well as the ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
