Design of high bulk moduli high entropy alloys using machine learning
Abstract In this work, the authors have demonstrated the use of machine learning (ML) models in the prediction of bulk modulus for High Entropy Alloys (HEA). For the first time, ML has been used for optimizing the composition of HEA to achieve enhanced bulk modulus values. A total of 12 ML algorithms were trained to…

Unraveling Paddy Soil Secrets: Surprising Contribution of Nonmicrobial Mechanisms to CO2 Emissions
Newswise — In a seminal study published recently in the journal Eco-Environment & Health, have shown that natural processes, especially reactions involving certain reactive oxygen species, play a big role in how paddy soils release CO2. This adds to our understanding of the world’s carbon balance. Researchers embarked on a journey to decode several aspects…

Biostimulants and herbicides a tool to reduce non-commercial yield tubers and improve potato yield structure
Abstract The basis for the study was a field experiment conducted in 2012–2014 in the production fields of multi-branch Soleks company in Wojnów, the district of Siedlce in eastern Poland. The experiment was established in a split-plot arrangement as a two-factor experiment in three replications. The first factor were: three cultivars of edible potato—Bartek, Gawin,…

Computational and statistical analyses of blood hemodynamic inside cerebral aneurysms for treatment evaluation of endovascular coiling
Abstract Diagnosis of aneurysm and possibility of aneurysm rupture are crucial for avoiding brain hemorrhage. In this work, blood stream inside internal carotid arteries (ICAs) are simulated in diverse working conditions to disclose the importance of hemodynamic factors on the rupture of aneurysm. The main attention of this study is to investigate the role of…

Weaponized genomics: potential threats to international and human security
Genetic technologies are revolutionizing human health. In parallel, geopolitical instability has prompted renewed discussions on the risks of DNA technology being weaponized in international conflict. With today’s changing security environment, we argue that risk assessments must be broadened from genetically targeted weapons to a series of new domains. Discussions on military deployment of DNA technology…

Effects of nanosilica on the properties of brine-base drilling fluid
Abstract In the process of drilling oil and gas wells, the shrinkage and falling of wellbore walls are often caused by the expansion of mud shale water. To date, conventional additives have been unable to plug the pore throats of shale rock with nanoscale pores and thus cannot effectively solve the problem of wellbore instability…
