Roof-mounted photovoltaic systems play a critical role in the global transition to renewable energy generation. An analysis of roof photovoltaic potential is an important tool for supporting decision-making and for accelerating new installations. State of the art uses 3D data to conduct potential analyses with high spatial resolution, limiting the study area to places with available 3D data. Recent advances in deep learning allow the required roof information from aerial images to be extracted. Furthermore, most publications consider the technical photovoltaic potential, and only a few publications determine the photovoltaic economic potential. Therefore, this paper extends state of the art by proposing and applying a methodology for scalable economic photovoltaic potential analysis using aerial images and deep learning. Two convolutional neural networks are trained for semantic segmentation of roof segments and superstructures and achieve an Intersection over Union values of 0.84 and 0.64, respectively. We calculated the internal rate of return of each roof segment for 71 buildings in a small study area. A comparison of this paper’s methodology with a 3D-based analysis discusses its benefits and disadvantages. The proposed methodology uses only publicly available data and is potentially scalable to the global level. However, this poses a variety of research challenges and opportunities, which are summarized with a focus on the application of deep learning, economic photovoltaic potential analysis, and energy system analysis.

The ongoing Israeli military assault on Gaza has caused a devastating collapse of healthcare infrastructure, resulting in an unprecedented surge in infectious diseases. The destruction of sanitation systems, restrictions on medical supplies, and displacement of civilians have created an environment conducive to the rapid spread of waterborne, vector‐borne, and antibiotic‐resistant infections. This paper draws from the insights of local Palestinian healthcare workers and recent medical missions conducted by FAJR Scientific, the Palestine American Medical Association, and Doctors Without Borders, examining infection control efforts under extreme constraints. The missions encountered major challenges, such as the absence of sterile equipment, inadequate access to clean water, and disrupted healthcare services. These conditions have exacerbated the spread of diseases such as hepatitis, meningitis, and polio, with severe impacts on Gaza's pediatric population. Efforts to implement infection control measures, such as telemedicine consultations, wound care protocols, and antibiotic stewardship, were heavily impeded by the ongoing blockade. The paper underscores the critical importance of lifting the siege to allow humanitarian access and to address the root causes of the infectious disease crisis in Gaza. It also highlights the resilience of Palestinian healthcare workers who continue to provide care under these dire circumstances. The recommendations outlined aim to support future medical teams working in conflict zones by providing practical strategies for infection prevention and control amidst such sustained violence. These efforts are contingent on international intervention and an end to the systematic blockade that has weaponized healthcare access. [ABSTRACT FROM AUTHOR]
