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.
View Article and Find Full Text PDFWing reduction is a common feature of upland insect communities. This phenomenon is thought to be primarily driven by selection against flight, which is typically unfavorable in upland environments due to high winds and cold temperatures. In some insect taxa, wing-reduction has been directly linked to increased fecundity.
