The Role of Family Medicine in Addressing the Maternal Health Crisis in the United States.

The United States (US) is experiencing a maternal health crisis, with high rates of maternal morbidity and mortality. The US has the highest rates of pregnancy-related mortality among industrialized nations. Maternal mortality has more than quadrupled over the last decades.

Pathfinder experiments with atom interferometry in the Cold Atom Lab onboard the International Space Station.

Deployment of ultracold atom interferometers (AI) into space will capitalize on quantum advantages and the extended freefall of persistent microgravity to provide high-precision measurement capabilities for gravitational, Earth, and planetary sciences, and to enable searches for subtle forces signifying physics beyond General Relativity and the Standard Model. NASA's Cold Atom Lab (CAL) operates onboard the International Space Station as a multi-user facility for fundamental studies of ultracold atoms and to mature space-based quantum technologies. We report on pathfinding experiments utilizing ultracold Rb atoms in the CAL AI.

Drug Testing Interpretation in the Peripartum Setting: Results of Clinician Survey.

Objectives: The objectives of this study were to (1) survey obstetrical and pediatric clinicians' experience, confidence, and training in maternal and neonatal drug testing interpretation; (2) determine their proficiency in drug test interpretation; and (3) assess predictors of correct interpretation.

Methods: We conducted a cross-sectional survey of clinicians caring for pregnant people or newborns at an urban academic center. We assessed clinicians' demographic characteristics, experience, confidence, and prior training in interpretation of maternal and newborn drug tests.

Electro-Nuclear Dynamics of Single and Double Ionization of H in Ultrafast Intense Laser Pulses.

We present an efficient method for modeling the single and double ionization dynamics of the H molecule in ultrashort, intense laser fields. This method is based on a semianalytical approach to calculate the time-dependent single and double molecular ionization rates and on a numerical approach to describe the vibrational motion that takes place in the intermediate molecular ion H. This model allows for the prediction of the single and double ionization probabilities of the H molecule to be made over a wide range of frequencies and laser intensities with limited computational time while providing a realistic estimate of the energy of the products of the dissociative ionization and of the Coulomb explosion of the H molecule.
