Separation of cortical arteries and veins in optical neurovascular imaging [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2014
Separation of arteries and veins in the cerebral cortex is of significant importance in the studies of cortical hemodynamics, such as the changes of cerebral blood flow, perfusion or oxygen concentration in arteries and veins under different pathological

Flavour constraints on light spin-1 bosons within a chiral Lagrangian approach [PDF]

open access: yes, 2023
We discuss the construction of the chiral Lagrangian for a light spin-1 boson, here denoted as X, featuring both vector and axial-vector couplings to light u, d, s quarks.

Asymptotic behavior of the eigenvalues of the p(x)-Laplacian [PDF]

open access: yesManuscripta Mathematica, 2014
We obtain asymptotic estimates for the eigenvalues of the p(x)-Laplacian defined consistently with a homogeneous notion of first eigenvalue recently introduced in the literature.

Existence of radial solutions for a $p(x)$-Laplacian Dirichlet problem [PDF]

open access: yesAdvances in Difference Equations, 2021
AbstractIn this paper, using variational methods, we prove the existence of at least one positive radial solution for the generalized$p(x)$p(x)-Laplacian problem$$ -\Delta _{p(x)} u + R(x) u^{p(x)-2}u=a (x) \vert u \vert ^{q(x)-2} u- b(x) \vert u \vert ^{r(x)-2} u $$−Δp(x)u+R(x)up(x)−2u=a(x)|u|q(x)−2u−b(x)|u|r(x)−2uwith Dirichlet boundary condition in ...

Observation of $J / ψ$ Electromagnetic Dalitz Decays to $X ( 1835 ) , X ( 2120 )$, and $X ( 2370 )$ [PDF]

open access: yes, 2022
Using a sample of about 10^{10} J/ψ events collected at a center-of-mass energy sqrt[s]=3.097 GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e^{+}e^{-}π^{+}π^{-}η^{'}, with η^{'}→γπ^{+}π^{-} and η^{'}→π^{+}π^{-}η, have been studied.

Inhomogeneous minimization problems for the p(x)-Laplacian [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2019
We study an inhomogeneous minimization problems associated to the $p(x)$-Laplacian. We make a thorough analysis of the essential properties of their minimizers and we establish a relationship with a suitable free boundary problem. On the one hand, we study the problem of minimizing the functional $J(v)=\int_Ω\Big(\frac{|\nabla v|^{p(x)}}{p(x)}+λ(x)χ_{\{

Near infra-red light treatment of Alzheimer’s disease [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2018
Alzheimer’s disease (AD) is a chronic neurodegenerative disease. The symptoms include memory and spatial learning difficulties, language disorders, and loss of motivation, which get worse over time, eventually ending in death. No effective treatments are

A free boundary problem for the -Laplacian [PDF]

open access: yesNonlinear Analysis: Theory, Methods & Applications, 2010
We consider the optimization problem of minimizing $\int_Ω|\nabla u|^{p(x)}+ λχ_{\{u>0\}} dx$ in the class of functions $W^{1,p(\cdot)}(Ω)$ with $u-ϕ_0\in W_0^{1,p(\cdot)}(Ω)$, for a given $ϕ_0\geq 0$ and bounded. $W^{1,p(\cdot)}(Ω)$ is the class of weakly differentiable functions with $\int_Ω|\nabla u|^{p(x)} dx0\}$, is a regular surface.

Seasonal Herbaceous Structure and Biomass Production Response to Rainfall Reduction and Resting Period in the Semi-Arid Grassland Area of South Africa

open access: yesAgronomy, 2020
Reduction in rainfall is amongst the major climate change manifestation phenomena, and will have a significant impact on grassland ecosystems. A split plot experimental design was used to investigate the interactive effect of rainfall reduction and ...
