In this paper, we consider the sharp interface limit of a matrix-valued Allen–Cahn equation, which takes form: $$\begin{aligned} \partial _t{\textbf{A}}=\Delta {\textbf{A}}-\varepsilon ^{-2}({\textbf{A}}{\textbf{A}}^{\textrm{T}}{\textbf{A}}-{\textbf{A}})\quad \text {with}\quad {\textbf{A}}:\Omega \subset {\mathbb {R}}^m\rightarrow {R}}^{n\times n}. \end{aligned}$$ We show that system is two-pha...

Introduction: Oral and dental (OD) disorders in children with Rubinstein-Taybi syndrome (RTS) are frequent but not well-known by dentists pediatricians due to the being extremely rare. Objective: To describe OD findings observed a 5-year-old girl RTS update literature. Clinical case: The patient presented following manifestations: prominent lower lip, narrow mouth opening, arched palate, histor...

BACKGROUND Rubinstein-Taybi syndrome (RSTS) is an extremely rare autosomal dominant genetic disease, with an estimated prevalence of one case per 125,000 live births. RSTS is characterized by typical facial features, microcephaly, broad thumbs and first toes, intellectual disability, and postnatal growth retardation. However, no standard diagnostic criteria are available for RSTS. In this revie...

models are successfully constructed and meaning emerges from the manipulation of symbols. It is moving when I observe that same excitement in students’ faces. Thus, my greatest dilemma is between my attraction to economic theory, on the one hand, and my doubts about its relevance, on the other. In this lecture I will try to decompose this basic dilemma into four parts: The dilemma of absurd con...

Figura 1 Angio-TC torácica con reconstrucción VR-3D, visión posterosuperior. En esta imagen podemos observar un arco aórtico completo, con origen independiente de los troncos supraaórticos: en el arco izquierdo, ligeramente de mayor calibre, se originan la arteria carótida y subclavia izquierdas y en el arco derecho, la arteria carótida, vertebral y subclavia derechas. AAo: ascending aorta (aor...

To the Editor : Rubinstein–Taybi syndrome (RTS) is a rare autosomal dominant disease (OMIM 180849), characterized by craniofacial dysmorphisms, broad thumbs and toes, mental and growth deficiency (1). RTSs has been associated with creb binding protein (CBP ) mutations and less frequently with EP300 mutations (2). CBP and p300 have high homology and are critical for many signaling pathways, espe...

Similarity solutions for the two-phase Rubinstein binary-alloy solidification problem in a semi-infinite material are developed. These new explicit obtained by considering two cases: A heat flux or convective boundary conditions at fixed face, and necessary sufficient on data also given order to have an instantaneous process. We show that all equivalent under some restrictions data. Moreover, t...
