Lagrangian gradient regression for the detection of coherent structures from sparse trajectory data.

Complex flows are often characterized using the theory of Lagrangian coherent structures (LCS), which leverages the motion of flow-embedded tracers to highlight features of interest. LCS are commonly employed to study fluid mechanical systems where flow tracers are readily observed, but they are broadly applicable to dynamical systems in general. A prevailing class of LCS analyses depends on reliable computation of flow gradients.

Spectral location for the universal scaling regime in Martian atmospheric turbulence.

Atmospheric turbulence, irregular fluctuations of the fluid state, is studied on Mars. Universality of the turbulence spectrum underpins atmospheric models where computational requirements preclude full fidelity simulations of the smallest scales. However, there are discrepancies among reports on the existence and spectral location of universal scaling in Martian atmospheric data.

Pregnancy After Panniculectomy Postbariatric Surgery: A Case Report.

Panniculectomy and abdominoplasty are two forms of abdominal body contouring commonly performed. There are literature reports of healthcare providers citing abdominoplasty as a contraindication to future pregnancy due to potential risks to the patient and fetus. Panniculectomy, outside of the reduced risks from the lack of rectus muscle plication, would have similar effects on the patient and fetus in future pregnancies.
