We report the discovery of three low-mass double-lined eclipsing binaries in the pre-main sequence Upper Scorpius association, revealed by K2 photometric monitoring of the region over ∼78 days. The orbital periods of all three systems are <5 days. We use the K2 photometry plus multiple Keck/HIRES radial velocities (RVs) and spectroscopic flux ratios to determine fundamental stellar parameters f...

Abstract This work presents a method for the definition of process capability profiles lined up with the specific business model of small software companies. The developed method is made up of a process, artifacts and guides that assist to obtain process profiles, considering the specific characteristics (business model, enterprise growth stage and value discipline) of each small software compa...

Gastric duplication cysts (GDC) lined with pseudostratified columnar ciliated epithelium (PCCE) are uncommon lesions that stem from a foregut developmental malformation. The clinical and radiological diagnosis is usually difficult. Definitive diagnosis can be established by histopathological examination. In this study, we report a rare case of a peri-gastric mass that was operated and reported ...
