Band separation and electric field prediction in square Bravais-Moiré photonic crystals.

In this study, we address three key challenges in photonic crystals: modeling of isolated flat bands, electric field prediction, and band separation in dispersion relations. Using twisted square Bravais lattices at specific angles, we create Bravais-Moiré photonic crystals exhibiting unique characteristics. These include band pairing and parallelism in certain Brillouin zones, enabling predictable electric field behavior and identification of isolated, flat band pairs within extensive band gaps.

Successful vaginal delivery and maternal and perinatal outcomes in patients with a history of cesarean section and labor trial: cross-sectional study.

Objectives: To determine the proportion of successful vaginal deliveries in women with prior cesarean section; to describe maternal and perinatal complications; and to examine the factors associated with vaginal delivery.

Materials And Methods: Descriptive cross-sectional study of women with a history of cesarean delivery, gestational age of more than 24 weeks, singleton live fetuses, with prior vaginal delivery who received care in a high complexity public institution in 2019. Patients with a history of more than one cesarean section or myomectomy were excluded.

Frequency of actionable Exomic secondary findings in 160 Colombian patients: Impact in the healthcare system.

Introduction: By 2021, the American College of Medical Genetics and Genomics (ACMG) published the last version of their secondary findings (SF) reporting recommendations for cases in which a person receives a genetic test.

Objective: To determine in a sample of the Colombian population the prevalence of SF for the 59 genes on the ACMG SF v2.0 list associated with 27 genetic diseases.
