The sputtering yield, the spatial distribution of the sputtered atoms, the energy distribution and the average energy of the sputtered atoms are important for numerous deposition techniques, as they determine the microstructure and the physical properties of the thin films. Using SRIM (Stopping and Range of Ions in Matter) simulations, …
Meshless methods are becoming increasingly popular in computational mechanics and engineering. Their main feature is the ability to manage complex geometries while avoiding the often tedious process of mesh generation required by the traditional methods. Various meshless approximations of linear differential operators appearing in the governing problem have been proposed …
RNA molecules dynamically interact with RNA-binding proteins (RBPs), which control various aspects of RNA fate, such as its processing, localisation, and stability. Intricate networks of protein-RNA interactions thereby regulate gene expression and have a profound effect on downstream cellular processes. Most RBPs recognise specific motifs on their bound RNAs, characterised …
Despite the large volume of recently published papers in the field of constrained multiobjective optimization, the understanding and characterization of constrained multiobjective optimization problems (CMOPs) for benchmarking multiobjective evolutionary algorithms (MOEAs) and the related constraint handling techniques (CHTs) remain unsatisfactory. Therefore, selecting appropriate CMOPs for benchmarking is challenging and lacks …
We are witnessing major shifts in ecosystems due to intense anthropogenic pressures on the environment in recent decades, including rapid climate change, which is one of the strongest drivers of a global biological response. Raptors, which are at the top of the trophic web, are important indicators of ecosystem health. …
News spreads in many patterns, structures, and dynamics that change throughout time. For a variety of reasons, certain news is only covered in a particular area. Language, economy, geography, politics, time zone, and culture are just a few of the many barriers that prevent news from reaching a larger audience. …
Cement production is one of the main contributors to mercury emissions in to the atmosphere. Many national and international legal i nstruments aim to control and reduce Hg emissions. Hg enters the cement production process as an impurity in fuels and raw materials, with the latter being the main source …
In this dissertation, we studied heterogeneous surface recombination of neutral oxygen atoms. We described plasma as a reliable source of neutral oxygen atoms and the behavior of neutral atoms in low-pressure plasma sustained by high-frequency discharges. Neutral atom density in the flowing afterglow and the recombination coefficient on several surfaces …
In the view of designing new nanostructured materials and tailoring their functional properties, understanding the nucleation and crystal growth mechanisms is becoming increasingly important. Nowadays, one of the most addressed scientific and social problems are those facing energy shortage and global warming. People started to realize the value and importance …
Epidermal growth factor receptor (EGFR) belongs to the ErbB family of receptor tyrosine kinases and plays an essential role in cell differentiation, migration, proliferation, and metabolism. Alterations in EGFR signalling were found in a number of cancers like lung, breast, colorectal cancer and gliomas, shown to be more aggressive and …
