Topological and geometric approach to the fixed-point theory with leakly rectified linear unit application
(Comenius University in Bratislava, 2023)In this paper, we focus on the Banach contraction principle on Sb-metric spaces. We present an alternative proof to the Banach contraction principle on Sb-metric spaces. Also, we investigate some geometric properties of ... -
Light Z′ signatures at the LHC
(American Physical Society, 2023)In this work, we discuss a distinctive pp -> Higgs -> Z'Z' -> 4l (l = e, mu) signal at the LHC, where the "Higgs" label refers to the Standard Model-like Higgs state discovered in 2012 or a lighter one in the framework of ... -
The use of double-integral of experimental EPR spectra for tooth enamel EPR dosimetry
(Oxford University Press, 2023)The presence of background signal in tooth enamel EPR dosimetry is the most challenging situation to overcome. This becomes even more important because it obscures the radiation-induced signal, especially at radiation doses ... -
Giant magnetoresistance of the electrodeposited FeCoCu/Cu multilayers: Metal oxide formation with NaOH in the electrolyte
(Polska Akademia Nauk, 2023)FeCo(CoO)Cu/Cu multilayers were prepared from the electrolytes containing various amounts of NaOH by the electrochemical deposition technique. The current density decreases with the increasing molarity of NaOH in the ... -
Monophoton events with light Higgs bosons in the secluded UMSSM
(American Physical Society, 2023)We explore the Higgs boson implications of a class of supersymmetric models, which extends the MSSM gauge group by a U(1)' symmetry, which is broken at low energy scales by vacuum expectation values of four MSSM singlet ... -
The impact of nonsingular memory on the mathematical model of hepatitis c virus
(World Scientific, 2023)In this research, we examine the nonsingular memory effect when implementing the Atangana-Baleanu (AB) fractional derivative in the Caputo sense to the Hepatitis C virus (HCV) model. For this purpose, first, the sufficient ... -
A modulus of smoothness for some banach function spaces
(Springer, 2023)Based on the Steklov operator, we consider a modulus of smoothness for functions in some Banach function spaces, which can be not translation invariant, and establish its main properties. A constructive characterization ... -
Improved photoluminescence properties of one-dimensional (1D) composite fibers of Ho@PVP and Yb@PVP prepared by electrospinning
(Elsevier, 2023)Two new Holmium3+ and Ytterbium3+ compounds, {Ho(4cba)3(phen)(H2O)} (1) and {Yb(4cba)3(phen)} (2) (4cba = 4-Cyanobenzoic acid, phen = 1,10-Phenanthroline) were synthesized. These compounds were then incorporated into a ... -
Evaluation of singlet oxygen generators of novel water-soluble perylene diimide photosensitizers
(Royal Society of Chemistry, 2023)In this study, novel photosensitizers using three water-soluble green perylene diimide (PDI)-based ligands were synthesized, which can be used as photosensitizing drugs in photodynamic cancer therapy (PDT). These three ... -
Taxonomic revision of the genus Nannomesochra Gurney, 1932 (Copepoda, Harpacticoida) with description of three new species
(Springer, 2023)A taxonomic revision of the genus Nannomesochra Gurney, 1932 was made based on the material collected from a wide range of localities along the Turkish coasts. Detailed morphological examination and comparisons of several ... -
Cu(II) coordination polymers containing dicyanamide and 2,2′-bipyridine: structural and antibacterial properties
(Pleiades Publishing, 2023)From reaction mixture containing the same reagents, the two Cu(II) complexes, with dicyanamide (dca) bridges, [Cu(bpy)(dca)2] n (1) and [Cu(bpy)Cl(dca)] n·H2O (2) (bpy = 2,2′-bipyridine) were prepared. The complexes were ... -
Improvement of saturation magnetization of sputtered Fe/Al multilayer thin films using Taguchi Method supported by ANOVA, response surface methodology and regression analysis
(Polska Akademia Nauk, 2023)Taguchi method has been conducted to improve the saturation magnetisation, M-s, of Fe/Al multilayer thin films deposited using a dual-target magnetron sputtering. The M-s values were obtained from the magnetic hysteresis ... -
Synthesis and investigation of carbonic anhydrase I and II activity of dihydrobenzo[h]quinazolin-2-yl thiourea compounds
(Springer, 2023)Thirteen novel compounds in a series of dihydrobenzo[h]quinazolin-2-yl thiourea compounds (7a–m) were synthesized and characterized using FT-IR, 1H, 13C NMR spectroscopy, and elemental analysis. Some inhibition parameters ... -
Exponential approximation of functions in lebesgue spaces with muckenhoupt weight
(Petrozavodsk State University, 2023)Using a transference result, several inequalities of ap-proximation by entire functions of exponential type in C(R), the class of bounded uniformly continuous functions defined on R - (-oo, +oo), are extended to the Lebesgue ... -
Martensitic ternary FeCrMn thin films sputtered from austenitic AISI 202 stainless steel target: Phase transition and corresponding magnetic properties under the influence of deposition rate
(Elsevier, 2023)The nanostructured materials exhibit quite different properties from their bulk counterparts. Therefore, in this work, phase transition from a commercial austenitic AISI 202 (Bulk FeCrMn) stainless steel to martensitic ... -
Effect of deposition potential and saccharin addition on structural, magnetic and magnetoresistance characteristics of NiCoFeCu films
(Walter De Gruyter GMBH, 2023)NiCoFeCu films were electrodeposited on Ti substrates at different deposition potentials and different concentrations of saccharin added to solution. Compositional analysis showed that although Ni was the highest concentration ... -
Microwave assisted synthesis of benzo-azacrown ethers and in vitro inhibition studies on hCA I–II
(Pleiades Publishing, 2023)In this study, macro-ringed benzo-aza-oxa-crown ethers were synthesized by a cyclization reaction between 2,2′-dithiodianiline and mono/di/tri/tetraethylene glycol dichloride/dibromide with Cs2CO3 as a catalyst under ... -
