Derivative measures [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
A characterization of those measures which are distribution derivatives is undertaken. For functions of n variables in BVC, the derivative measures are absolutely continuous with respect to Hausdorff n − 1 n - 1 measure.

Derivators, pointed derivators and stable derivators [PDF]

open access: yesAlgebraic & Geometric Topology, 2013
We develop some aspects of the theory of derivators, pointed derivators, and stable derivators. As a main result, we show that the values of a stable derivator can be canonically endowed with the structure of a triangulated category. Moreover, the functors belonging to the stable derivator can be turned into exact functors with respect to these ...

Deriving Derivatives [PDF]

open access: yesSSRN Electronic Journal, 2013
Quantitative structuring is a rigorous framework for the design of financial products. We show how it incorporates traditional investment ideas while supporting a more accurate expression of clients' views. We touch upon adjacent topics regarding the safety of financial derivatives and the role of pricing models in product design.

Extending Derivations

open access: yesPublications of the Research Institute for Mathematical Sciences, 1984
Let (\({\mathcal A},G,\tau)\) be a \(C^*\)-dynamical system, where G is a compact abelian group, \({\mathcal A}^{\tau}\) be the fixed point algebra, and \(\delta_ 0:{\mathcal D}_ 0\to {\mathcal A}^{\tau}\) be a \({}^*\)- derivation defined on a \({}^*\)-subalgebra \({\mathcal D}_ 0\) of \({\mathcal A}^{\tau}\).

On the Lundgren–Townsend model of turbulent fine scales [PDF]

open access: yes, 1993
The strained-spiral vortex model of turbulent fines scales given by Lundgren [Phys. Fluids 25, 2193 (1982)] is used to calculate vorticity and velocity-derivative moments for homogeneous isotropic turbulence. A specific form of the relaxing spiral vortex

Distributed shape derivative via averaged adjoint method and applications [PDF]

open access: yes, 2015
The structure theorem of Hadamard-Zol\'esio states that the derivative of a shape functional is a distribution on the boundary of the domain depending only on the normal perturbations of a smooth enough boundary.

Strong Superconvergence of Finite Element Methods for Linear Parabolic Problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
We study the strong superconvergence of a semidiscrete finite element scheme for linear parabolic problems on 𝑄=Ω×(0,𝑇], where Ω is a bounded domain in ℛ𝑑(𝑑≤4) with piecewise smooth boundary. We establish the global two order superconvergence results for

Genetic Algorithm Captured the Informative Bands for Partial Least Squares Regression Better on Retrieving Leaf Nitrogen from Hyperspectral Reflectance

open access: yesRemote Sensing, 2022
Nitrogen is a major nutrient regulating the physiological processes of plants. Although various partial least squares regression (PLSR) models have been proposed to estimate the leaf nitrogen content (LNC) from hyperspectral data with good accuracies ...

German Youth Language: Word-Formation Types of Suffix Nouns and Their Semantic Relations

open access: yesНаучный диалог, 2020
The article is devoted to the study of word-formation types in modern German youth slang and a description of their systemic paradigmatic relations. The research material was a large group of suffix nouns, presented in the dictionaries of youth slang, as

[Creatinine] can change in an unexpected direction due to the volume change rate that interacts with kinetic GFR: Potentially positive paradox

open access: yesPhysiological Reports, 2022
[Creatinine] was proved to change in the opposite direction of the kinetic GFR (GFRK), but does the [creatinine] also change in the opposite direction of the volume rate?
