This paper proposes a solution to the challenging task of autonomously landing Unmanned Aerial Vehicles (UAVs). An onboard computer vision module integrates the vision system with the ground control communication and video server connection. The vision platform performs feature extraction using the Speeded Up Robust Features (SURF), followed by fast Structured Forests edge detection and then smoothing with a Kalman filter for accurate runway sidelines prediction.

- The study focused on understanding the stigma faced by MSM with HIV, transgender women with HIV, and healthcare providers in Dominican Republic healthcare settings.
- Data was collected through focus groups and interviews, identifying four primary stigma themes: migrant stigma, religious stigma, SGM stigma, and HIV stigma.
- The results highlight the severe impact of stigma on mental health, suggesting that effective interventions should tackle both structural barriers and cultural norms that contribute to stigma in HIV care.
Image-based spatial transcriptomics platforms are powerful tools often used to identify cell populations and describe gene expression in intact tissue. Spatial experiments return large, high-dimension datasets and several open-source software packages are available to facilitate analysis and visualization. Spatial results are typically imperfect.

- Wing reduction in upland insects is primarily driven by unfavorable conditions for flight, such as high winds and cold temperatures.
- A study on the stonefly Zelandoperla fenestrata showed a trade-off between dispersal capabilities (flight muscles and wing length) and reproductive output (ovarian mass).
- The findings highlight that reduced flight capability can lead to increased fecundity, indicating that insects may adapt their energy allocation based on environmental conditions.
