Pseudo-differential Operators with Semi-Quasielliptic Symbols Over p-adic Fields

In this article, we study pseudo-differential equations involving semi-quasielliptic symbols over p-adics. We determine the function spaces where such equations have solutions. We introduce the space of infinitely pseudo-differentiable functions with respect to a semi-quasielliptic operator. By using these spaces we show the existence of a regularization effect for certain parabolic equations over p-adics.Comment: Accepted in Journal of Mathemaatical Analysis and its Application

Physical and Sexual Violence, Mental Health indicators, and treatment seeking among street-based population groups in Tegucigalpa, Honduras

To establish the prevalence of exposure to physical and sexual violence, mental health symptoms, and medical treatment-seeking behavior among three street-based subpopulation groups in Tegucigalpa, Honduras, and to assess the association between sociodemographic group, mental health indicators, and exposure to violence

The Facioscapulohumeral Syndrome: A Report of Two Cases

Two patients developed progressive muscle weakness in adult life. The initial diagnosis of polymyositis was made in both cases, but subsequent studies and the distribution of muscle involvement suggested facioscapulohumeral myopathy. Other investigators have proposed that this syndrome may result from either genetic or acquired causes. In our patients, the disorder was probably a sequela of polymyositis
