Computing support for testing equal values of the figurative numbers in the Pascal triangle
(Proceedings of the 7th Technium Conference 2020, 2020-09-15)
In this paper we deal with a method for the determination of numbers in a Pascal triangle that are simultaneously triangular, tetrahedral and pentaedroidni.
The collected results, obtained by mathematical analysis, were ...
Green synthesis and characterization of nontoxic L-methionine capped silver and gold nanoparticles
(Elsevier, 2019-12-11)
The simple green method for synthesis of stable L-Methionine (L-Met) capped silver (Ag@LM NPs) and gold (Au@LM NPs) nanoparticles (NPs) without adding any additional reduction agent or stabilizer was developed. Colloidal ...
“Soft Protein Corona” as the Stabilizer of the Methionine-Coated Silver Nanoparticles in the Physiological Environment: Insights into the Mechanism of the Interaction
(MDPI, 2022-08-11)
The study of the interactions between nanoparticles (NPs) and proteins has had a pivotal
role in facilitating the understanding of biological effects and safe application of NPs after exposure to the physiological ...
Nanospectroscopy of thiacyanine dye molecules adsorbed on silvernanoparticle clusters
(Elsevier, 2017-10-25)
The adsorption of thiacyanine dye molecules on citrate-stabilized silver nanoparticle clusters drop-cast onto freshly cleaved mica or highly oriented pyrolytic graphite surfaces is examined using colocalized surface-enhanced ...
Solid-State Synthesis of Silver Nanoparticles and Their Catalytic Application in Methylene Blue Reduction
(Wiley-VCH GmbH, 2020-09-08)
The silver nanoparticles (Ag NPs) were successfully synthesized by a facile solid-state chemical method. Ag NPs were obtained by a mechanochemical reaction between silver nitrate and sodium citrate, with the constant ...
Figurative numbers contribution in perceiving the legality in numerous strings tasks and log-term memory of numerous data
(Modestum, 2019-01-27)
Contemporary mathematics teaching is mostly reduced to the application of algebraic
formulas and algebraic procedures. The visual-logical approach in solving
mathematical tasks is very little represented in teaching ...
Flexibility of curves on a single-sheet hyperboloid
Hyperbolic towers are towers in the shape of a single-sheet hyperboloid, and they are interesting in architecture. In this paper, we deal with the infinitesimal bending of a curve on a hyperboloid of one sheet; that is, we ...
Generating function for the figurative numbers of regular polyhedron
(Hindawi, 2020-04-14)
In this paper, we are going to demonstrate a method for determining the generating functions of tetrahedral, hexahedral, octahedral, dodecahedral, and icosahedral figurative numbers. The method is based on the differences ...
Initial improvement of the hybrid accelerated gradient descent process
(Cambridge University Press, 2018-08-01)
We improve the convergence properties of the iterative scheme for solving unconstrained optimisation problems introduced in Petrovic et al. [‘Hybridization of accelerated gradient descent method’, Numer. Algorithms (2017), ...
Hybrid modification of accelerated double direction method
(Hindawi, 2018-11-06)
We present a hybridization of the accelerated gradient method with two vector directions. This hybridization is based on the usage of a chosen three-term hybrid model. Derived hybrid accelerated double direction model keeps ...
