Transtorno do espectro autista: Diagnóstico e compreensão da temática pelos responsáveis

open access: yesRevista Contexto & Saúde, 2022
O Transtorno do Espectro Autista (TEA) é uma condição voltada aos aspectos do neurodesenvolvimento, e tenha ganhado destaque na literatura pelo aumento das taxas de diagnósticos e importância da compreensão do transtorno, porém uma ênfase menor é dada ...

Transmutations between Singular and Subsingular Vectors of the N=2 Superconformal Algebras [PDF]

open access: yes, 1999
We present subsingular vectors of the N=2 superconformal algebras other than the ones which become singular in chiral Verma modules, reported recently by Gato-Rivera and Rosado.

Removing singularities [PDF]

open access: yesJournal of High Energy Physics, 2003
Big bang/crunch curvature singularities in exact CFT string backgrounds can be removed by turning on gauge fields. This is described within a family of {SL(2)xSU(2)xU(1)_x}/{U(1)xU(1)} quotient CFTs. Uncharged incoming wavefunctions from the ``whiskers'' of the extended universe can be fully reflected if and only if a big bang/crunch curvature ...

The balance in Gender in the Arabic language [PDF]

open access: yesآداب الرافدين, 1987
A comparison between the isotopes and likenesses in the Arab tongue reveals to us a phenomenon indicating consistency and balance, which is lost in many issues scattered in separate Augusts that we can sum up in one chapter.

Singular mean-field control games with applications to optimal harvesting and investment problems [PDF]

open access: yes, 2014
This paper studies singular mean field control problems and singular mean field stochastic differential games. Both sufficient and necessary conditions for the optimal controls and for the Nash equilibrium are obtained.

A Swarming Approach for the Novel Second Order Perturbed Pantograph Lane–Emden Model Arising in Astrophysics

open access: yesAxioms, 2022
The purpose of this study is to provide a mathematical construction based on the novel singular perturbed model of the second kind (NSPM-SK) using the standard form of the Lane–Emden. The singular Lane–Emden types of the models have abundant applications

On nonexistence of Baras--Goldstein type for higher-order parabolic equations with singular potentials [PDF]

open access: yes, 2009
An analogy of nonexistence result by Baras and Goldstein (1984), for the heat equation with inverse singular potential, is proved for 2mth-order linear parabolic equations with Hardy-supercritical singular potentials.

La “carencia de límites de lo conceptual” y los pensamientos singulares en McDowell

open access: yesRevista Filosofía UIS, 2021
En este trabajo se analiza la propuesta en torno de los pensamientos singulares o “pensamientos de re” del filósofo contemporáneo John McDowell. Nuestra estrategia es abordar dicha reconstrucción a partir de la tesis de “la carencia de límites de lo ...

String and Fivebrane Solitons: Singular or Non-singular? [PDF]

open access: yes, 1991
We ask whether the recently discovered superstring and superfivebrane solutions of D=10 supergravity admit the interpretation of non-singular solitons even though, in the absence of Yang-Mills fields, they exhibit curvature singularities at the origin ...

Analytic Expressions for Singular Vectors of the $N=2$ Superconformal Algebra [PDF]

open access: yes, 1995
Using explicit expressions for a class of singular vectors of the $N=2$ (untwisted) algebra and following the approach of Malikov-Feigin-Fuchs and Kent, we show that the analytically extended Verma modules contain two linearly independent neutral ...
