OBJECTIVE To describe how Medical Benefits Schedule (MBS) chronic disease (CD) item claims vary by sociodemographic and health characteristics in people with heart disease, asthma or diabetes. DESIGN, SETTING AND PARTICIPANTS A cross-sectional analysis of linked unit-level MBS and survey data from the first 102,934 participants enrolled in the 45 and Up Study, a large-scale cohort study in Ne...

In this paper we present some results on the dispersionless limit of the Toda lattice equations viewed as the semiclassical limit of an equation involving certain Toeplitz operators. We consider both nonperiodic and periodic boundary conditions. For the nonperiodic case the phase space is the Riemann sphere, while in the periodic case it is the torus C/Z2. In both cases we prove precise estimat...

A novel method is elaborated for the electromagnetic scattering from periodical arrays of scatterers embedded in a polarizable background. A dyadic periodic Green's function is introduced to calculate the scattered electric field in a lattice of dielectric or metallic objects. The method exhibits strong advantages: discretization and computation of the field are restricted to the volume of the ...

Basic notions regarding classical integrable systems are reviewed. An algebraic description of the classical integrable models together with the zero curvature condition description is presented. The classical r-matrix approach for discrete and continuum classical integrable models is introduced. Using this framework the associated classical integrals of motion and the corresponding Lax pair ar...

The particle-particle-particle-mesh (PM) force field scheme [1], [2] is an efficient approach to account for both the long-range and short-range electrostatic interactions in the simulation of biological systems. Resolving the particle-mesh term in real-space [2], [3] improves the original approach of Hockney et al. [1] by allowing for the inclusion of non-periodic boundary conditions. To date,...

Since the Consensus on chronic gastritis in China was developed in September 2006 in Shanghai, much progress has been made in the diagnosis and treatment of chronic gastritis, including the Operative Link for Gastritis Assessment (OLGA), European Consensus On management of precancerous conditions of gastric cancer, and Maastricht-IV consensus. Therefore, the “2012 Chinese National Consensus Mee...

BACKGROUND In developed countries, primary health care increasingly involves the care of patients with multiple chronic conditions, referred to as multimorbidity. AIM To describe the epidemiology of multimorbidity and relationships between multimorbidity and primary care consultation rates and continuity of care. DESIGN OF STUDY Retrospective cohort study. SETTING Random sample of 99 997 ...

We study the Pöschl-Teller equation in complex domain and deduce infinite families of TQ and Bethe ansatz equations, classified by four integers. In all these models the form of T is very simple, while Q can be explicitly written in terms of the Heun function. At particular values there is a interesting interpretation in terms of finite lattice spin2 XXZ quantum chain with ∆ = cos π L (for free...

We report a new United Atom Force Field (denoted MSUA) for molecular dynamics simulation of the uoro polymers: Poly(tetra uoroethylene) (PTFE), Poly(vinylidene uoride) (PVDF), and Ethylene-tetra uoroethylene (ETFE). The MSUA was obtained from combining quantum chemistry and experimental results. Using the MSUA and periodic boundary conditions, we carried out molecular dynamics simulations using...

In this work we introduce a relaxed version of the constant positive linear dependence constraint qualification (CPLD) that we call RCPLD. This development is inspired by a recent generalization of the constant rank constraint qualification from Minchenko and Stakhovski that was called RCR. We show that RCPLD is enough to ensure the convergence of an augmented Lagrangian algorithm and asserts t...
