Nonautonomous equations and almost reducibility sets [PDF]
Electronic Journal of Qualitative Theory of Differential Equations, 2021 For a nonautonomous differential equation, we consider the almost reducibility property that corresponds to the reduction of the original equation to an autonomous equation via a coordinate change preserving the Lyapunov exponents.

Reducibility of zero curvature equations
Electronic Journal of Differential Equations, 2004 By introducing a natural reducibility definition for zero curvature equations, we give a Floquet representation for such systems and show applications to the reducibility problem for quasiperiodic 2-dimensional linear systems and to fiberwise linear ...

Understanding and ad hoc Explanation: A Case of Russell’s Reducibility Axiom [PDF]
Омский научный вестник: Серия "Общество. История. Современность", 2022 The article examines the common interpretation of the axiom of reducibility in Principia Mathematica according to which the axiom cannot be considered as logical, which casts doubt on the success of the program of logicism.

Copper-Based Silica Nanotubes as Novel Catalysts for the Total Oxidation of Toluene
Nanomaterials, 2023 Cu (10 wt%) materials on silica nanotubes were prepared via two different synthetic approaches, co-synthesis and wetness impregnation on preformed SiO2 nanotubes, both as dried or calcined materials, with Cu(NO3)2.5H2O as a material precursor.

Reduction of solid fuel consumption in sintering of Indian iron ore [PDF]
Science of Sintering, 2015 The present investigation deals with the sinterability of Goa (India) iron ore having high Fe (65.2%) content. The sinter basicity (CaO/SiO2) and its MgO were varied in the 2.0 to 2.5 and 1.5 to 3.0 range.

Instance reducibility and Weihrauch degrees [PDF]
Logical Methods in Computer Science, 2022 We identify a notion of reducibility between predicates, called instance reducibility, which commonly appears in reverse constructive mathematics. The notion can be generally used to compare and classify various principles studied in reverse constructive
