We study the system of self-dual Maxwell field coupled to 3D gravity with torsion, with Maxwell field modified by a topological mass term. General structure of the field equations reveals a new, dynamical role of the classical central charges, and gives a simple correspondence between self-dual solutions with torsion and their Riemannian counterparts. We construct two exact self-dual solutions,...

We present a case of refractory ileocolonic Crohn's disease in a 27-year-old female treated with dual ustekinumab and vedolizumab biologic therapy. She had mucosal healing for the first time in 13 years after a 10-month treatment of ustekinumab overlapped with 6 months of vedolizumab. No side effects were observed during the 6 months of dual biologic therapy. Short-term dual biologic therapy ma...

The aim of this paper is to derive (by using two operators, representable by a Jacobi matrix) a family of q-orthogonal polynomials, which turn to be dual to alternative q-Charlier polynomials. A discrete orthogonality relation and a three-term recurrence relation for these dual polynomials are explicitly obtained. The completeness property of dual alternative q-Charlier polynomials is also esta...

We study U(1) gauge theories with a modified Villain action. Such can naturally be coupled to electric and magnetic matter, display exact electric-magnetic duality. In their simplest formulation without $\theta$-term, such are ultra-local. extend the discussion $\theta$-terms, that $\theta$ periodicity is for free theory, show imposing duality results in local, but not ultra-local lattice actio...

BACKGROUND Dual eligible Medicare and Medicaid beneficiaries consume disproportionate shares of both programs. OBJECTIVES To compare Medicare and Medicaid expenditures of elderly dual eligible beneficiaries with non-dual eligible beneficiaries based on their long-term care (LTC) use. RESEARCH DESIGN Secondary analysis of linked MAX and Medicare data in seven states. SUBJECTS Dual eligible...

OBJECTIVE The control of gait requires executive and attentional functions. As preterm children show executive and attentional deficits compared to full-term children, performing concurrent tasks that impose additional cognitive load may lead to poorer walking performance in preterm compared to full-term children. Knowledge regarding gait in preterm children after early childhood is scarce. We ...

BACKGROUND E-cigarettes have grown popular. The most common pattern is dual use with conventional cigarettes. Dual use has raised concerns that it might delay quitting of cigarette smoking. This study examined the relationship between long-term use of e-cigarettes and smoking cessation in a 2-year period. METHODS A nationally representative sample of 2028 US smokers were surveyed in 2012 and ...
