Sign language images dataset from Mexican sign language.

Sign language is a complete language with its own grammatical rules, akin to any spoken language used worldwide. It comprises two main components: static words and ideograms. Ideograms involve hand movements and contact with various parts of the body to convey meaning.

Nucleus segmentation of white blood cells in blood smear images by modeling the pixels' intensities as a set of three Gaussian distributions.

The precise segmentation of white blood cells (WBCs) within blood smear images is a significant challenge with implications for both medical research and image processing. Of particular importance is the often neglected task of accurately segmenting WBC nuclei, an aspect that currently lacks dedicated methodologies. This paper introduces a straightforward and efficient method designed to fill this critical gap, providing an effective solution for the efficient segmentation of WBC nuclei.

Systematic segmentation method based on PCA of image hue features for white blood cell counting.

Leukocyte (white blood cell, WBC) count is an essential factor that physicians use to diagnose infections and provide adequate treatment. Currently, WBC count is determined manually or semi-automatically, which often leads to miscounting. In this paper, we propose an automated method that uses a bioinspired segmentation mimicking the human perception of color.

Application of Dynamic Fragmentation Methods in Multimedia Databases: A Review.

Fragmentation is a design technique widely used in multimedia databases, because it produces substantial benefits in reducing response times, causing lower execution costs in each operation performed. Multimedia databases include data whose main characteristic is their large size, therefore, database administrators face a challenge of great importance, since they must contemplate the different qualities of non-trivial data. These databases over time undergo changes in their access patterns.

Isoindoline Derivatives of α-Amino Acids as Cyclooxygenase 1 and 2 Inhibitors.

IC50 values were obtained for two series of isoindolines derived from α-amino acids over cyclooxygenase 1 and 2 (COX-1 and COX-2). In order to explain the biological activity observed, a structure-activity relationship (SAR) model was achieved for the tested compounds and 19 reference compounds with known selective inhibitory activity, through the correlation of the binding energies calculated from rigid docking of the best conformations into the catalytic sites of COX-1 and COX-2, as well as their molecular descriptors: Log P, molecular weight (MW), volume (V), and solvation energy (Esol) versus their experimental IC50 values by MLR and LS-SVM methods. The model probed whether the COX-1 and COX-2 inhibitory activities of the isoindolines correlate with steric, hydrophobic, and thermodynamic parameters.
