The properties of steel after equal channel angular pressing (ECAP) and subsequent high-temperature annealing are investigated. ECAP leads to an increase in strength properties of steel, to a decrease in plasticity, and to localization of plastic strain. High strength properties and localization of ...
In contexts outside of geometry, the symbol is occasionally used to show that two numbers are approximately, but not exactly, equal. Example 1: ππ π≅3.14π≅3.14 Example 2:When working with irrational numbers, the golden ratioϕϕcould be approximately expressed asϕ≅1.618ϕ...

Repetitive DNA sequences, comprising up to 50 % of the genome in all eukaryotes, play important roles in a wide range of cellular functions, such as transcriptional regulation, genome stability, and cellular differentiation. However, due to technical difficulties in differentiating their sequences, D...

In rat, Slxl1 remains single-copy and appears non-functional, based upon low to no gene expression across tissues (Figures S1B and S1C). In mice, Slxl1 maintains the intron-exon structure of Sycp3 (Figure S2A), and a Slxl1-related gene family member, Slx, was acquired on an ...
