On the Maximum Pair Multiplicity of Pulsar Cascades [PDF]

Astrophysical Journal, 2018
We study electron–positron pair production in polar caps of energetic pulsars to determine the maximum multiplicity of pair plasma a pulsar can produce under the most favorable conditions.

Numerical construction of structured matrices with given eigenvalues

Special Matrices, 2019
We consider a structured inverse eigenvalue problem in which the eigenvalues of a real symmetric matrix are specified and selected entries may be constrained to take specific numerical values or to be nonzero.

Acceleration of Multiple Precision Matrix Multiplication using Ozaki scheme [PDF]

arXiv, 2023
Optimized multiple precision basic linear computation, especially matrix multiplication, is crucial for solving ill-conditioned problems. The recently proposed Ozaki scheme, which implements accurate matrix multiplication using existing optimized low precision matrix multiplication, is known to be useful for multiple precision as well.

An introduction to multiplicity issues in clinical trials: the what, why, when and how.

International Journal of Epidemiology, 2016
In clinical trials it is not uncommon to face a multiple testing problem which can have an impact on both type I and type II error rates, leading to inappropriate interpretation of trial results.

Existence of Positive Solutions for a System of Singular Fractional Boundary Value Problems with p-Laplacian Operators

Mathematics, 2020
We investigate the existence and multiplicity of positive solutions for a system of Riemann–Liouville fractional differential equations with singular nonnegative nonlinearities and p-Laplacian operators, subject to nonlocal boundary conditions which ...

Accelerated Multiple Precision Matrix Multiplication using Strassen's Algorithm and Winograd's Variant [PDF]

JSIAM Letters, Vol. 6 (2014) p. 81-84, 2014
The Strassen algorithm and Winograd's variant accelerate matrix multiplication by using fewer arithmetic operations than standard matrix multiplication. Although many papers have been published to accelerate single- as well as double-precision matrix multiplication by using these algorithms, no research to date has been undertaken to accelerate ...

Leadership Multiplicities Before and During the Post-Truth Era

Administrative Sciences, 2018
Drawing from the ontology of the lack (Laclau and Mouffe 1985), aesthetic theory (Adorno 1997); practice theory (Bourdieu 2002), art perception theory (Bourdieu 1968), and storytelling theory (Boje 2001), we discuss leadership multiplicities and post ...
