Some Properties of Euler’s Function and of the Function τ and Their Generalizations in Algebraic Number Fields

Mathematics, 2021
In this paper, we find some inequalities which involve Euler’s function, extended Euler’s function, the function τ, and the generalized function τ in algebraic number fields.

Finiteness theorems for algebraic tori over function fields

Comptes Rendus. Mathématique, 2021
We present a number of finiteness results for algebraic tori (and, more generally, for algebraic groups with toric connected component) over two classes of fields: finitely generated fields and function fields of algebraic varieties over fields of type ...

Wind turbine load validation in wakes using wind field reconstruction techniques and nacelle lidar wind retrievals [PDF]

Wind Energy Science, 2021
This study proposes two methodologies for improving the accuracy of wind turbine load assessment under wake conditions by combining nacelle-mounted lidar measurements with wake wind field reconstruction techniques.

Some Properties of Extended Euler’s Function and Extended Dedekind’s Function

Mathematics, 2020
In this paper, we find some properties of Euler’s function and Dedekind’s function. We also generalize these results, from an algebraic point of view, for extended Euler’s function and extended Dedekind’s function, in algebraic number fields ...

Reducing pesticides without organic certification? Potentials and limits of an intermediate form of agricultural production

Cogent Food & Agriculture, 2023
A growing number of farmers’ cooperatives cultivate crops without chemical pesticides, but also without organic certification. How does this intermediate form of agriculture between conventional and organic production function?

Testing the Beta-Lognormal Model in Amazonian Rainfall Fields Using the Generalized Space q-Entropy

Entropy, 2017
We study spatial scaling and complexity properties of Amazonian radar rainfall fields using the Beta-Lognormal Model (BL-Model) with the aim to characterize and model the process at a broad range of spatial scales.

Holographic topological defects in a ring: role of diverse boundary conditions

Journal of High Energy Physics, 2022
We investigate the formation of topological defects in the course of a dynamical phase transition with different boundary conditions in a ring from AdS/CFT correspondence.

A quantum framework for AdS/dCFT through fuzzy spherical harmonics on S 4

Journal of High Energy Physics, 2020
We consider a non-supersymmetric domain-wall version of N $$ \mathcal{N} $$ = 4 SYM theory where five out of the six scalar fields have non-zero classical values on one side of a wall of codimension one.
