Machine learning using random forest to model heavy metals removal efficiency using a zeolite-embedded sheet in water by N.D. Takarina, N. Matsue, E. Johan, A. Adiwibowo, M.F.N.K. Rahmawati, S.A. Pramudyawardhani, T. Wukirsari

“…Based on the random forest models, the important variables affecting copper removal efficiency using zeolite-embedded sheet were its contents in water, followed by water temperature and potential of hydrogen. Conversely, lead and zinc removal efficiency was influenced mostly by potential of hydrogen. …”

Quasi-Normal Modes: The “Electrons” of Black Holes as “Gravitational Atoms”? Implications for the Black Hole Information Puzzle by Christian Corda

“…This is a model of BH somewhat similar to the historical semiclassical model of the structure of a hydrogen atom introduced by Bohr in 1913. In a certain sense, QNMs represent the “electron” which jumps from a level to another one and the absolute values of the QNMs frequencies, “triggered” by emissions (Hawking radiation) and absorption of particles, represent the energy “shells” of the “gravitational hydrogen atom.” …”

Insights of cellular and molecular changes in sugarcane response to oxidative signaling by Lucas Felipe Silva, Kellya F. M. Barreto, Helaine Cristiane Silva, Iara Dantas de Souza, Carlos H. S. G. Meneses, Adriana F. Uchôa, Katia C. Scortecci

“…Abstract Main conclusion Significant changes in the proteome highlight essential metabolic adaptations for development and oxidative signaling induced by the treatment of young sugarcane plants with hydrogen peroxide. These adaptations suggest that hydrogen peroxide acts not only as a stressor but primarily as a signaling molecule, triggering specific metabolic pathways that regulate growth and plant resilience. …”

Deciphering antioxidant interactions via data mining and RDKit by Lucas B. Ayres, Justin T. Furgala, Carlos D. Garcia

“…The analysis focuses on the most commonly reported compounds and mixtures and considers how various chemical descriptors (number of atoms, number of heavy atoms, number of heteroatoms, number of carbon atoms, number of oxygen atoms, number of nitrogen atoms, number of chloride atoms, polar surface area, molecular weight, number of aromatic rings, logP, and hydrogen bond counts) affect the response. Out of those, our analysis showed that hydrogen bonding plays an important role in determining how antioxidants interact, potentially affecting the overall behavior of mixtures. …”

Computational Modeling and Theoretical Calculations on the Interactions between Spermidine and Functional Monomer (Methacrylic Acid) in a Molecularly Imprinted Polymer by Yujie Huang, Qiujin Zhu

“…The simulation results show that SPD and MAA form a stable complex via hydrogen bonding. At 1 : 5 SPD to MAA ratio, the binding energy is minimum, while the amount of transferred charge between the molecules is maximum; SPD and MAA form a stable complex at 1 : 5 molar ratio through six hydrogen bonds. …”
