DOI: 10.1016/j.actbio.2016.11.015
Abstract: A large fraction of the volume of Beluga whale (Delphinapterus leucas) teeth consists of cementum, a mineralized tissue which grows throughout the life of the animal and to which the periodontal ligaments attach. Annular growth… read more here.

DOI: 10.18632/oncotarget.15038
Abstract: Aquatic mammals, such as cetaceans experience various depths, with accordingly diverse oxygenation, thus, cetaceans have developed adaptations for hypoxia, but mechanisms underlying this tolerance to low oxygen are unclear. Here we analyzed VHL and HIF-2α,… read more here.

Improved Beluga Whale Optimization for Solving the Simulation Optimization Problems with Stochastic Constraints
Sign Up to like & getrecommendations! Published in 2023 at "Mathematics"
DOI: 10.3390/math11081854
Abstract: Simulation optimization problems with stochastic constraints are optimization problems with deterministic cost functions subject to stochastic constraints. Solving the considered problem by traditional optimization approaches is time-consuming if the search space is large. In this… read more here.
