Several oil paintings, suspected of being stolen, were found in the possession of an art dealer in Tel-Aviv, Israel. The authors were asked to determine if these paintings were the stolen ones, based on photographs, stretchers, and frames submitted by the alleged owners in France. A physical match was found between two of the questioned paintings and two stretchers. Another painting was identified as being previously affixed to the original frame by several nails. The fourth painting was identified as being the one photographed by the alleged owner. This identification was done by comparing micro-topography marks revealed by the illumination conditions of that photograph and of the questioned painting.

Loss of facial features can result from a variety of traumatic events. Throughout history, humans have worked to develop materials and methods to repair such defects. Epithesis first appeared in medical literature in the 16th century.

Thermogravimetric analyses up to 600°C revealed distinct degradation patterns under inert and oxidative conditions. Significant degradation of paint initiates at around 360°C and concludes at 500°C in a nitrogen atmosphere.

The increasing demand for sustainable alternatives to conventional antifungal agents has prompted extensive research into the antifungal properties of plant essential oils (EOs). This study investigates the use of EOs mixture (Origanum vulgare, Moringa oleifera, and Cinnamomum verum) for controlling fungal deterioration in wall paintings at the archaeological Youssef Kamal Palace in Nag Hammadi, Egypt. Fungal isolates were collected from deteriorated wall paintings and identified using phenotypic and genotypic analyses.

Currently, the automotive sector is showing increased demands regarding the color of cars in general, but especially the quality and the time of painting, in particular. Companies working in this industry, especially in specialized painting services, must perform work of impeccable quality in the shortest possible time in order to be efficient. Color differences that appear in different areas of the car result from the use of different formulas for obtaining color.

Morphological profiling has recently demonstrated remarkable potential for identifying the biological activities of small molecules. Alongside the fully supervised and self-supervised machine learning methods recently proposed for bioactivity prediction from Cell Painting image data, we introduce here a semisupervised contrastive (SemiSupCon) learning approach. This approach combines the strengths of using biological annotations in supervised contrastive learning and leveraging large unannotated image data sets with self-supervised contrastive learning.
