state-of-the-art psychotherapy for anxiety disorders represents some of the most efficacious treatments in the mental health literature. nevertheless, these treatments are not panacea. too many patients drop out of treatment, response rates leave room for improvement, and residual symptomatology is common. the quest to improve therapy for patients suffering from mental disorders necessitates on...

OBJECTIVES In 2013, the American Academy of Pediatrics published a policy statement calling for pediatricians to be informed about the need for specific pediatric medical necessity language because children deserve "the intent embedded in Medicaid." This study aims to explore the definitions and determinations of medical necessity in Medicaid Managed Care (MMC), document the relevant language u...

One of the most basic examples of matroid duality is the following. Let G be a graph imbedded in the plane and let G∗ be its topological dual graph. If M(G) is the cycle matroid of G, then the dual matroid M∗(G) = M(G∗). If G is a connected graph that is 2-cell imbedded in a surface of demigenus d > 0 (the demigenus is equal to 2 minus the euler characteristic of the surface), then M∗(G) 6= M(G...

We propose a new 1–3 piezoelectric composite comprised of armchair single-walled carbon nanotubes imbedded in a piezoceramic matrix which we call a NRPEC (nanotube reinforced 1–3 piezoelectric composite). Values of effective piezoelectric and elastic moduli of the NRPEC determined through a micromechanical analysis are found to be significantly higher than those of the 1–3 piezoelectric composi...

I N R E C E N T years Dr. Herman J. Schaefer 3 has shown that heavy primary cosmic ray particles can be expected to produce ionization tracks as long as several millimeters in living tissue. These tracks reach central ionization intensities of thousands of roentgens, and significant radial radiation to the order of cell diameters. Since no particle can be accelerated artificially to compare dir...

Two different geometries have been proposed to explain the dust emission from pre-mainsequence stars: flared disks and “classical” geometrically-thin optically-thick disks imbedded in optically thin halos. We show that only imaging observations can differentiate these two morphologies because flux measurements can never distinguish between them. A model constructed with one geometry implies an ...
