Analysis and application of an overlapped FEM-BEM for wave propagation in unbounded and heterogeneous media
(Elsevier, 2022)
info:eu-repo/semantics/article,
An overlapped continuous model framework, for the Helmholtz wave propagation problem in unbounded regions comprising bounded heterogeneous media, was recently introduced and analyzed by the authors (2020) [10]. The continuous ...
Optical system based on multiplexed FBGs to monitor hand movements
(IEEE, 2021)
info:eu-repo/semantics/article,
This contribution reports the development and characterization of an optical system based on parallel Fiber Bragg Gratings (FBGs) to monitor the movements of the wrist and fingers of a hand. The system consisted of a ...
Tryptophan levels as a marker of auxins and nitric oxide signaling
(MDPI, 2022)
info:eu-repo/semantics/article,
The aromatic amino acid tryptophan is the main precursor for indole-3-acetic acid (IAA),
which involves various parallel routes in plants, with indole-3-acetaldoxime (IAOx) being one of
the most common intermediates. ...
On certain subspaces of p for 0 < p ≤ 1 and their applications to conditional quasi-greedy bases in p-Banach spaces
(Springer, 2021)
info:eu-repo/semantics/article,
We construct for each 0<p≤1 an infinite collection of subspaces of ℓp that extend the example of Lindenstrauss (Bull. Acad. Polon. Sci. Sér. Sci. Math. Astronom. Phys. 12, 539–542, 1964) of a subspace of ℓ1 with no ...
Multigrid solvers for multipoint flux approximations of the Darcy problem on rough quadrilateral grids
(Springer, 2020)
info:eu-repo/semantics/article,
In this work, an efficient blackbox-type multigrid method is proposed for solving multipoint flux approximations of the Darcy problem on logically rectangular grids. The approach is based on a cell-centered multigrid ...
Lipschitz free p-spaces for 0 < p < 1
(SpringerHebrew University Magnes Press, 2020)
info:eu-repo/semantics/article,
This paper initiates the study of the structure of a new class of p-Banach spaces, 0 <p < 1, namely the Lipschitz free p-spaces (alternatively called Arens—Eells p-spaces) Fp(M) over p-metric spaces. We systematically ...
Non-superreflexivity of Garling sequence spaces and applications to the existence of special types of conditional bases
(Instytut Matematyczny, 2020)
info:eu-repo/semantics/article,
We settle in the negative the problem of the superreflexivity of Garling sequence spaces by showing that they contain a complemented subspace isomorphic to a non-superreflexive mixed-norm sequence space. As a by-product, ...
The importance of the urea cycle and its relationships to polyamine metabolism during ammonium stress in Medicago truncatula
(Oxford University Press, 2022)
Artículo / Artikulua,
The ornithine–urea cycle (urea cycle) makes a signifcant contribution to the metabolic responses of lower photosynthetic eukaryotes to episodes of high nitrogen availability. In this study, we compared the role of the plant ...
Lipschitz algebras and Lipschitz-Free spaces over unbounded metric spaces
(Oxford University Press, 2021)
Artículo / Artikulua,
We investigate a way to turn an arbitrary (usually, unbounded) metric space M into a bounded metric space B in such a way that the corresponding Lipschitz-free spaces F(M) and F(B) are isomorphic. The construction we provide ...
Biological solubilisation of leather industry waste in anaerobic conditions: effect of chromium (III) presence, pre-treatments and temperature strategies
(MDPI, 2022)
Artículo / Artikulua,
Collagen-based polymers and their blends have attracted considerable interest for new
materials development due to their unique combination of biocompatibility, physical and mechanical
properties and durability. Leather, ...
