Sampling technique affects the population structure assessments of fiddler crab Minuca vocator (Herbst, 1804) (Ocypodidae: Gelasiminae)

Nauplius
We examined how the sampling technique can affect the evaluation of Minuca vocator (Herbst, 1804) population structure. We used two sampling procedures: catch-per-unit-effort (CPUE) and quadrat technique (QT).

Electropermanent Magnetic Muscles: Power‐Efficient, Low‐Voltage, Compact Magnetic Actuators to Power Wearables and Untethered Robots

Advanced Intelligent Systems, EarlyView.
This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

Modeling and Forecasting of Lake Malombe Fish Biomass and Catch Per Unit Effort (CPUE)

, 2020
Lake Malombe fish stocks have been depleted by chronic overfishing. Various management approaches (co-management, command control, and ecosystem-based management to fisheries) have been used to manage the fishery. However, the lack of an accurate predictive model has hampered their success.

Navigating an STI diagnosis: The role of social support, intergenerational learning, and transformative growth among Black women

American Journal of Community Psychology, EarlyView.
Abstract Black women face a myriad of challenges that heighten their susceptibility to sexually transmitted infections (STIs), resulting in a disproportionate impact of STIs among this population. Yet, there is a lack of research that explores how women navigate these diagnoses with resilience.
