A distributional approach to fractional Sobolev spaces and fractional variation: Existence of blow-up [PDF]
Journal of Functional Analysis, 2018 We introduce the new space B V α ( R n ) of functions with bounded fractional variation in R n of order α ∈ ( 0 , 1 ) via a new distributional approach exploiting suitable notions of fractional gradient and fractional divergence already existing in the ...

To Blow-Up or Not to Blow-Up for a Granular Kinetic Equation
Physica D: Nonlinear PhenomenaA simplified kinetic description of rapid granular media leads to a nonlocal Vlasov-type equation with a convolution integral operator that is of the same form as the continuity equations for aggregation-diffusion macroscopic dynamics. While the singular behavior of these nonlinear continuity equations is well studied in the literature, the extension ...

BLOW UP: DEPOIS DAQUELA IMAGEM
ModaPalavra e-periódico, 2008 Blow Up de Antonionni é daquelas obras que, embora datadas, não perdem o frescor da atualidade. O artigo centra atenção em questões que, em meu entendimento, são decisivas ao se pensar os dias atuais: imagem, mídia e moda. Foi através de um diálogo muito

Journal of Differential Equations, 2019 We obtain a blow-up result for solutions to a semi-linear wave equation with scale-invariant dissipation and mass and power non-linearity, in the case in which the model has a “wave like” behavior.

Sub-logistic source can prevent blow-up in the 2D minimal Keller-Segel chemotaxis system [PDF]
Journal of Mathematics and Physics, 2017 It is well-known that the Neumann initial-boundary value problem for the minimal-chemotaxis-logistic system in a 2D bounded smooth domain has no blow-up for any choice of parameters. Here, for a large class of kinetic terms including sub-logistic sources,

Blow-Up Rate Estimates for a System of Reaction-Diffusion Equations with Gradient Terms
International Journal of Mathematics and Mathematical Sciences, 2019 This paper is concerned with the blow-up properties of Cauchy and Dirichlet problems of a coupled system of Reaction-Diffusion equations with gradient terms. The main goal is to study the influence of the gradient terms on the blow-up profile.

Nonlocal Kirchhoff diffusion problems: local existence and blow-up of solutions
Nonlinearity, 2018 In this paper, we study a diffusion model of Kirchhoff-type driven by a nonlocal integro-differential operator. As a particular case, we consider the following diffusion problem where [u]s is the Gagliardo seminorm of u, is a bounded domain with ...

On the blow-up of a non-local parabolic problem
, 2006 We investigate the conditions under which the solution of the initial-boundary value problem of the non-local equation ut=Δu+λf(u)/(∫Ωf(u)dx)p, where Ω is a bounded domain of RN and f(u) is a positive, increasing, convex function, performs blow-up.

Molecular Oncology, EarlyView.Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...
