Phase-stabilized complex-decorrelation angiography
Biomedical Optics Express, 2021 In this study, we developed a novel phase-stabilized complex-decorrelation (PSCD) optical coherence tomography (OCT) angiography (OCTA) method that can generate high quality OCTA images. This method has been validated using three different types of OCT systems and compared with conventional complex- and amplitude-based OCTA algorithms.

Understanding element solution energies in nickelbase alloys using machine learning
Materials Research Express, 2023 The design of nickelbase superalloys requires to tune the content of different phases with a composition of Ni _3 A, either to strengthen the alloy ( $\gamma ^{\prime} $ -phase, Ni _3 Al, γ ″-phase, Ni _3 Nb) or to influence its grain size and avoid ...

Phase Stability and Deformation Behavior of TiZrHfNbO High-Entropy Alloys
Frontiers in Materials, 2020 Strengthened by Oxygen doping, the single-phase body-center-cubic (BCC) TiZrHfNbO refractory high-entropy alloys (HEAs) become strong and ductile. However, phase stability at intermediate temperature and the effects of Oxygen addition on the deformation ...

Stability of A15 type phases [PDF]
Solid State Communications, 1974 Abstract Previous works dealing with the stability of the A15 phases are reviewed. Data for over 60 known A15 phases are used to develop criteria for stability which may be applied to hypothetical A15 phases. Occurrence of these phases is examined in terms of the valence bond concepts of the Engel-Brewer correlation and in its frequency with changes ...

Brownmillerites CaFeO2.5 and SrFeO2.5 as Catalyst Support for CO Oxidation
Molecules, 2021 The support material can play an important role in oxidation catalysis, notably for CO oxidation. Here, we study two materials of the Brownmillerite family, CaFeO2.5 and SrFeO2.5, as one example of a stoichiometric phase (CaFeO2.5, CFO) and one existing ...

Island Stability in Phase Space [PDF]
Journal of Physics: Conference Series, 2018 Starting with a conventional bump on tail problem, which is equivalent to finding a solution of the Vlasov/Fokker-Planck equation in the presence of the phase space island, we obtain a primary equilibrium state. The stability of this state is investigated as a function of the effective velocity-space drag and diffusion, as well as the width of these ...
