Fuel Consumption as a Spatial Proxy: Measuring Urban Infrastructure Performance in Juba, South Sudan

This study proposes vehicular fuel consumption per kilometer as a scalable, low-cost spatial proxy to evaluate urban infrastructure performance in data-scarce Juba, South Sudan, revealing that intra-city routes with poor surface conditions and high junction density impose significantly higher economic and energy burdens compared to inter-city travel.

Integrating Qibla-Oriented Design with Energy Efficiency: A Comparative Simulation Study of Building Shape and Orientation Across Diverse Egyptian Climatic Regions

This study demonstrates that while building geometry is the primary driver of energy efficiency in Egypt's diverse climates, aligning structures with the Qibla direction incurs only a minimal energy penalty (under 7%), proving that cultural orientation requirements can be successfully integrated with sustainable design strategies.

Sensitivity of image-derived wound-healing proxies to sparse visit schedules and image framing: a retrospective multi-dataset audit

This retrospective multi-dataset audit reveals that image-derived wound-healing proxies are highly sensitive to sparse visit schedules and image framing, demonstrating that current data supports only a failure-mode analysis rather than calibrated clinical prognosis due to unvalidated segmentation errors, lack of incremental value from CNNs over occupancy metrics, and instability under scale variations.
