Elliptic genera of 2d (0,2) gauge theories from brane brick models

We compute the elliptic genus of abelian 2d (0, 2) gauge theories corresponding to brane brick models. These theories are worldvolume theories on a single D1-brane probing a toric Calabi-Yau 4-fold singularity. We identify a match with the elliptic genus of the non-linear sigma model on the same Calabi-Yau background, which is computed using a new localization formula. The matching ...

The Coexistence of Antiphospholipid Syndrome and Systemic Lupus Erythematosus in Colombians

Objectives To examine the prevalence and associated factors related to the coexistence of antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) in a cohort of Colombian patients with SLE, and to discuss the coexistence of APS with other autoimmune diseases (ADs). Method A total of 376 patients with SLE were assessed for the presence of the following: 1) confirmed ...
