Monocyte-derived cytokines in multiple sclerosis
Clinical and Experimental Immunology, 2003 SUMMARYMS is an inflammatory, presumably autoimmune, disease mediated by the activation of T cells, B cells and monocytes (MO). Inflammation is thought to occur early during the relapsing-remitting phase of MS (RRMS), whereas in the later phases of MS such as secondary progressive MS (SPMS), inflammation tends to diminish.

On (anti-)multiplicative generalized derivations
Glasnik matematički, 2012 Let $R$ be a semiprime ring and let $F, f : R \to R$ be (not necessarily additive) maps satisfying $F(xy)=F(x)y+xf(y)$ for all $x, y \in R.$ Suppose that there are integers $m$ and $n$ such that $F(uv)=mF(u)F(v)+nF(v)F(u)$ for all $u, v$ in some nonzero ideal $I$ of $R.$ Under some mild assumptions on $R, $ we prove that there exists $c \in C(I ...

The Influence of White Noise and the Beta Derivative on the Solutions of the BBM Equation
Axioms, 2023 In the current study, we investigate the stochastic Benjamin–Bona–Mahony equation with beta derivative (SBBME-BD). The considered stochastic term is the multiplicative noise in the Itô sense.

Foundations, 2023 We investigate the spatial discretization of a stochastic semilinear superdiffusion problem driven by fractionally integrated multiplicative space–time white noise. The white noise is characterized by its properties of being white in both space and time,

Generalized multiplicative α-skew derivations on rings
Boletim da Sociedade Paranaense de Matemática, 2022 Let R be a semiprime (or prime) ring and U be a nonzero ideal of R. In the present paper, we study the notions of multiplicative generalized α-skew derivations on ideals of R and prove that if R admits a multiplicative generalized α-skew derivation G associated with a nonzero additive map d and an automorphism α, then d is necessarily an α-skew ...

Geodesy and Geodynamics, 2023 To solve the complex weight matrix derivative problem when using the weighted least squares method to estimate the parameters of the mixed additive and multiplicative random error model (MAM error model), we use an improved artificial bee colony ...

An introduction to non-smooth convex analysis via multiplicative derivative
Journal of Taibah University for Science, 2019 In this study, *-directional derivative and *-subgradient are defined using the multiplicative derivative, making a new contribution to non-Newtonian calculus for use in non-smooth analysis.

Soil characterization by near-infrared spectroscopy and principal component analysis
Revista Ciência Agronômica, 2021 This research aimed to use principal component analysis (PCA) as an exploratory method for spectral data of soil absorbance from the Baturité Massif and Central Hinterland (Ceará State, Brazil) to verify the potential of the technique in soil ...
