Self-Organized Nanostructures Generated on Metal Surfaces under Electron Irradiation
Quantum Beam Science, 2021 Irradiation of high-energy electrons can produce surface vacancies on the exit surface of thin foils by the sputtering of atoms. Although the sputtering randomly occurs in the area irradiated with an intense electron beam of several hundred nanometers in

Proceedings of the National Academy of Sciences, 2001 Recent progress in black hole research is illustrated by three examples. We discuss the observational challenges that were met to show that a supermassive black hole exists at the center of our galaxy. Stellar-size black holes have been studied in x-ray binaries and microquasars.

Collective Excitations of 14N and 10B Nuclei [PDF]
Kirkuk Journal of Science, 2016 The nuclear structure of 14N and 10B nuclei are studied in framework two collective excitation approximations. The first approximation is hole-hole Tamm-Dancoff Approximation (hh TDA) and the second is hole-hole Random Phase Approximation (hh RPA).

The Electronic Journal of Combinatorics, 2001 The celebrated Regularity Lemma of Szemerédi asserts that every sufficiently large graph $G$ can be partitioned in such a way that most pairs of the partition sets span $\epsilon$-regular subgraphs. In applications, however, the graph $G$ has to be dense and the partition sets are typically very small.

Thallium Isotopes Reveal Brine Activity During Carbonatite Magmatism
Geochemistry, Geophysics, Geosystems, 2021 Carbonatite volcanism remains poorly understood compared to silicic volcanism due to the scarcity of carbonatite volcanoes worldwide and because volcanic H2O and CO2—major components in carbonatite volcanic systems—are not well preserved in the rock ...
