This study was to examine the effect of triangulation on depression in children. Clinical samples and nonclinical samples were taken from Utah and Illinois. Families were assessed for marital satisfaction and stability, family triangulation, and children’s depression levels by the Marital Adjustment Test, Marital Status Inventory, Nuclear Family Triangulation, and Children’s Depression Inventor...

Some years ago one of the two authors in collaboration with F. Hermann studied in [FH] some modular varieties of small dimension. These are related to the orthogonal group O(2, n). In particular using some exceptional isogenies between orhogonal and symplectic groups, they used techniques of both “the worlds”. The most significant variety they studied in [FH] was related to O(2, 6) or —equivale...

OBJECTIVES The goals of this study were (1) to provide estimates of diagnostic stability for a sample of young children diagnosed with attention-deficit/hyperactivity disorder (ADHD) after undergoing comprehensive multidisciplinary assessments and (2) to identify baseline child and family characteristics that predict diagnostic stability over time. METHODS Children aged 3 to 6 years, 11 month...

We show that uniformly global asymptotic stability and input-to-state stability for a family of ordinary diierential equations are equivalent to uniformly global exponential stability and a nonlinear H1 estimate, respectively , under suitable nonlinear changes of variables.

Influenza A virus (H1N1), which arose in 2009, constituted the fourth pandemic after the cases of 1918, 1957, and 1968. This new variant was formed by a triple reassortment, with genomic segments from swine, avian, and human influenza origins. The objective of this study was to analyze sequences of hemagglutinin (n=2038) and neuraminidase (n=1273) genes, in order to assess the extent of diversi...

In this paper we show that uniformly global asymptotic stability for a family of ordinary diierential equations is equivalent to uniformly global exponential stability under a suitable nonlinear change of variables. The same is shown for input-to-state stability and input-to-state exponential stability, and for input-to-state exponential stability and a nonlinear H 1 estimate.

In this paper we show that uniformly global asymptotic stability for a family of ordinary differential equations is equivalent to uniformly global exponential stability under a suitable nonlinear change of variables. The same is shown for input-to-state stability and input-to-state exponential stability, and for input-to-state exponential stability and a nonlinear H∞ estimate.
