One-loop calculations of hyperon polarizabilities under the large N_c consistency condition

The spin-averaged electromagnetic polarizabilities of the hyperons $\Lambda$ and $\Sigma$ are calculated within the one-loop approximation by use of the dispersion theory. The photon and meson couplings to hyperons are determined so as to satisfy the large N_c consistency condition. It is shown that in order for the large N_c consistency condition to hold exotic hyperon states such as $\Sigma^{**}$ with I=2 and J=3/2 are required in the calculation of the magnetic polarizability of the $\Sigma$ state.Comment: 17 pages, REVTeX, no figure

Calculating Prevalence of Comorbidity and Comorbidity Combinations with Diabetes in Hospital Care in Sweden Using a Health Care Record Database

Abstract. We have studied the prevalence of comorbidity in the Stockholm EPR corpus containing almost 600,000 patients from 900 clinics using the ICD- 10 codes assigned to each patient record. The proportion of patients with a valid ICD-10 code was 83.0%, and 41.5 % of these had at least one comorbidity. The most frequent comorbidity combination with type 2 diabetes was essential hypertension (43.1%). Our approach seems feasible for large scale analysis of diagnostic codes in EPR databases.
