Mulla Sadra on the External Difference between Accident and Subject of Philosophical Secondary Intelligible [PDF]

حکمت معاصر, 2014
The Mulla Sadra’s view on the existence of philosophical secondary intelligible has been interpreted and expressed diversely. What is easily understood from Sadra’s statements is that the external aspect of philosophical secondary intelligible is ...

Solar peculiar motion inferred from dipole anisotropy in redshift distribution of quasars appears to lie along the Galactic Centre direction

Scientific Reports
According to the Cosmological Principle an observer stationary with respect to the comoving coordinates of the expanding universe should find the redshift distribution of distant quasars to be isotropic.

Hybrid bottom-up and top-down framework resolves discrepancies in Canada’s oil and gas methane inventories

Communications Earth & Environment
Estimating accurate oil and gas methane emissions has been a global challenge, highlighted by a twofold discrepancy between atmospheric measurement-based estimates and emission inventories.

On existence of a variational regularization parameter under Morozov's discrepancy principle

CoRR
Morozov's discrepancy principle is commonly adopted in Tikhonov regularization for choosing the regularization parameter. Nevertheless, for a general non-linear inverse problem, the discrepancy $\|F(x_α^δ)-y^δ\|_Y$ does not depend continuously on $α$ and it is questionable whether there exists a regularization parameter $α$ such that $τ_1δ\leq \|F(x_α ...

Numerical Analysis of a Fractional Cauchy Problem for the Laplace Equation in an Annular Circular Region

Fractal and Fractional
The Cauchy problem for the Laplace equation in an annular bounded region consists of finding a harmonic function from the Dirichlet and Neumann data known on the exterior boundary.

Mind the Gap! Linking Equality‐Based Respect Norms with General and Specific Tolerance

Social Inclusion
This research investigates the extent of Poles’ tolerance of Jews through the lens of equality‐based respect norms and how these norms translate into general and specific tolerance.

On saturation of the discrepancy principle for nonlinear Tikhonov regularization in Hilbert spaces

Applied Mathematics Letters
In this paper we revisit the discrepancy principle for Tikhonov regularization of nonlinear ill-posed problems in Hilbert spaces and provide some new and improved saturation results under less restrictive conditions, comparing with the existing results in the literature.

Regularization properties of the discrepancy principle for Tikhonov regularization in Banach spaces: Regularization properties of the discrepancy principle for Tikhonov regularization in Banach spaces

, 2012
The stable solution of ill-posed non-linear operator equations in Banach space requires regularization. One important approach is based on Tikhonov regularization, in which case a one-parameter family of regularized solutions is obtained. It is crucial to choose the parameter appropriately. Here, a variant of the discrepancy principle is analyzed.
