For a nonlinear optical fiber system, simulation results show up to 24 % reach increase. In addition, the proposed CM scheme enables rate adaptivity in single-wavelength systems, offering six different data rates between 450 Gbit/s and 666 Gbit/s.Minimum density power divergence estimation provides a general framework for robust statistics,…[Read more]

The displacement hypothesis of eight-node cubic elements is selected as the shape function of digital volume correlation (DVC), and the Newton-Raphson iterative method is selected to solve the partial differential equation to measure the displacement field. In order to ensure that the DVC algorithm is usable under the large rotation condition, the…[Read more]

Placenta accreta spectrum is most commonly diagnosed antenatally or at the time of delivery, but it may also present in the postpartum period.

A 29-year-old primigravid patient without risk factors for placenta accreta spectrum had an uncomplicated vaginal birth with normal blood loss and delivery of an intact-appearing placenta. Five days…[Read more]
