Septic Return Flow Pathlines, Endpoints, and Flows Based on the Urban Miami-Dade Groundwater Model.

Miami-Dade County (MDC) has over 112,000 septic systems, some of which are at risk of compromise due to water table rise associated with sea level rise. MDC is surrounded by protected water bodies, including Biscayne Bay, with environmentally sensitive ecosystems and is underlain by highly transmissive karstic limestone. The main objective of the study is to provide first estimates of the locations and magnitudes of septic return flows to discharge endpoints.

Quantifying Information without Entropy: Identifying Intermittent Disturbances in Dynamical Systems.

A system's response to disturbances in an internal or external driving signal can be characterized as performing an implicit computation, where the dynamics of the system are a manifestation of its new state holding some memory about those disturbances. Identifying small disturbances in the response signal requires detailed information about the dynamics of the inputs, which can be challenging. This paper presents a new method called the Information Impulse Function (IIF) for detecting and time-localizing small disturbances in system response data.

Pelvic floor symptom changes in pessary users.

Objective: The objective of the study was to compare pelvic floor symptom changes in patients who continue vs discontinue pessary use, and determine whether changes predict pessary continuation.

Study Design: Women fitted with pessaries completed the Pelvic Floor Distress Inventory-20 (PFDI-20) before and after initiating pessary use. Scores were compared in women who continued vs discontinued pessaries.
