BLOW UP: DEPOIS DAQUELA IMAGEM

open access: yesModaPalavra 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

To Blow-Up or Not to Blow-Up for a Granular Kinetic Equation

open access: yesPhysica D: Nonlinear Phenomena
A 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 phenomena for a class of metaparabolic equations with time dependent coeffcient

open access: yesAIMS Mathematics, 2017
This paper deals with the initial boundary value problem for a metaparabolic equations withtime dependent coeffcient. Under suitable conditions on initial data, a blow-up criterion which ensuresthat u cannot exist all time is given, and an upper bound ...

Blowing up generalized Kahler 4-manifolds

open access: yes, 2011
We show that the blow-up of a generalized Kahler 4-manifold in a nondegenerate complex point admits a generalized Kahler metric. As with the blow-up of complex surfaces, this metric may be chosen to coincide with the original outside a tubular ...

Blow-Up Rate Estimates for a System of Reaction-Diffusion Equations with Gradient Terms

open access: yesInternational 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.

Blow up profiles for a quasilinear reaction-diffusion equation with weighted reaction

open access: yes, 2019
We perform a thorough study of the blow up profiles associated to the following second order reaction-diffusion equation with non-homogeneous reaction: $$ \partial_tu=\partial_{xx}(u^m) + |x|^{\sigma}u^p, $$ in the range of exponents $10$.

Similarity stabilizes blow up [PDF]

open access: yesJournal of Differential Equations, 1999
The blow-up of solutions to a quasilinear heat equation is studied using a similarity transformation that turns the equation into a nonlocal equation whose steady solutions are stable. This allows energy methods to be used, instead of the comparison principles used previously.

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

open access: yesFEBS Open Bio, EarlyView.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Total blow-up of a quasilinear heat equation with slow-diffusion for non-decaying initial data [PDF]

open access: yesMathematica Bohemica, 2019
We consider solutions of quasilinear equations $u_t=\Delta u^m + u^p$ in $\mathbb R^N$ with the initial data $u_0$ satisfying $0 < u_0< M$ and $\lim_{|x|\to\infty}u_0(x)=M$ for some constant $M>0$. It is known that if $0<m<p$ with $p>1$,

Sub-logistic source can prevent blow-up in the 2D minimal Keller-Segel chemotaxis system

open access: yes, 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,
