EXPONENTIAL GENERALIZED DISTRIBUTIONS [PDF]

open access: yes, 2010
In this paper we generalize the Fourier transform from the space of tempered distributions to a bigger space called exponential generalized distributions.

Asymptotic Fourier and Laplace transforms for vector-valued hyperfunctions [PDF]

open access: yes, 2022
We study Fourier and Laplace transforms for Fourier hyperfunctions with values in a complex locally convex Hausdorff space. Since any hyperfunction with values in a wide class of locally convex Hausdorff spaces can be extended to a Fourier hyperfunction,

High Hydrostatic Pressure‐Assisted Extraction of High‐Molecular‐Weight Melanoidins from Black Garlic: Composition, Structure, and Bioactive Properties

open access: yesJournal of Food Quality, Volume 2019, Issue 1, 2019., 2019
Melanoidin is one of the most important ingredients in black garlic due to the high nutritional values and biological functions. High hydrostatic pressures from 200 to 500 MPa were employed to extract the melanoidins from black garlic for improving the extraction efficiency and enhancing the activities.

Estimating Mental Health Conditions of Patients with Opioid Use Disorder

open access: yesJournal of Addiction, Volume 2019, Issue 1, 2019., 2019
Objectives. Noninvasive estimation of cortical activity aberrance may be a challenge but gives valuable clues of mental health in patients. The goal of the present study was to characterize specificity of electroencephalogram (EEG) electrodes used to assess spectral powers associated with mental health conditions of patients with opioid use disorder ...

Fourier hyperfunctions of general type

open access: yesKyoto Journal of Mathematics, 1988
The author studies vector valued Fourier hyperfunctions valued in a complex Hilbert space \(H\) which is not necessarily separable. This is a direct generalization of the author and \textit{Sh. Nagamachi} [Proc. Japan Acad. 51, 558-561 (1975; Zbl 0333.46031) and J. Math., Tokushima Univ. 9, 1-33 (1975; Zbl 0315.46039)]. He realizes \(H\)-valued Fourier

Modulation Spectra Morphological Parameters: A New Method to Assess Voice Pathologies according to the GRBAS Scale

open access: yesBioMed Research International, Volume 2015, Issue 1, 2015., 2015
Disordered voices are frequently assessed by speech pathologists using perceptual evaluations. This might lead to problems caused by the subjective nature of the process and due to the influence of external factors which compromise the quality of the assessment. In order to increase the reliability of the evaluations, the design of automatic evaluation

Ulam Problem for the Cosine Addition Formula in Sato Hyperfunctions

open access: yesJournal of Function Spaces, Volume 2015, Issue 1, 2015., 2015
We prove the Ulam problem for the cosine addition formula in the spaces of Schwartz distributions and Sato hyperfunctions with respect to bounded distributions and bounded hyperfunctions.

Perturbation Theory for Abstract Volterra Equations

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
We consider additive perturbation theorems for subgenerators of (a, k)‐regularized C‐resolvent families. A major part of our research is devoted to the study of perturbation properties of abstract time‐fractional equations, primarily from their importance in modeling of various physical phenomena. We illustrate the results with several examples.
