Partial Derivative Approach to the Integral Transform for the Function Space in the Banach Algebra [PDF]

open access: yesEntropy, 2020
We investigate some relationships among the integral transform, the function space integral and the first variation of the partial derivative approach in the Banach algebra defined on the function space.

A Partial Derivative Approach to the Change of Scale Formula for the Function Space Integral [PDF]

open access: yesEntropy, 2020
We investigate the partial derivative approach to the change of scale formula for the functon space integral and we investigate the vector calculus approach to the directional derivative on the function space and prove relationships among the Wiener ...

Partial Soft Derivative [PDF]

open access: yesCommunications in Advanced Mathematical Sciences
The concept of soft derivative, introduced by Molodtsov in 1999, is one of the fundamental concepts in soft analysis. The handled paper defines partial soft derivative and studies some of its basic properties, such as the relation between partial soft ...

Estimates For An Integral In Lp Norm Of The (N + 1)-Th Derivative Of Its Integrand [PDF]

open access: yes, 2000
Basing on Taylor’s formula with an integral remaider, an integral is estimated in Lp norm of the (n + 1)-th derivative of its integrand, and the Iyengar’s inequality and many other useful inequalities are ...

In creatinine kinetics, the glomerular filtration rate always moves the serum creatinine in the opposite direction

open access: yesPhysiological Reports, 2021
Introduction When the serum [creatinine] is changing, creatinine kinetics can still gauge the kidney function, and knowing the kinetic glomerular filtration rate (GFR) helps doctors take care of patients with renal failure.

On canonical homotopy operators for partial derivative in Fock type spaces in C-n

open access: yes, 2001
We show that a certain solution operator for partial derivative in a space of forms square integrable against e(-\z\2) is canonical, i.e.. that it gives the minimal solution when applied to a partial derivative -closed form.
