Street artists around the world have been prominent in depicting issues concerning COVID-19, but the role of street art in public-making during the pandemic is unexplored. Despite burgeoning street art scenes in many African countries since the early 2000s, African street art is relatively neglected in critical street art scholarship. In response, this paper examines street art created during the pandemic in East African countries, principally Uganda, Kenya, Rwanda, and Tanzania, and explores the ways in which it is engaged in highly distinctive forms of public-making. Drawing primarily on qualitative online interviews with East African artists creating street art, and image analysis using online search tools, the paper argues that street art in urban areas is attempting to create knowledgeable publics through countering disinformation about the pandemic, to responsiblize publics through public health messaging and, through community activism, to build resilient publics. The paper concludes that street art is potentially an important tool in tackling the COVID-19 pandemic in East African countries due to the proximity, and mutual constitution of, creative practices and publics, which emerge from the embedding of street art within the social spaces of cities and everyday experiences of the pandemic.

Civil infrastructure assets' contribution to countries' economic growth is significantly increasing due to the rapid population growth and demands for public services. These civil infrastructures, including roads, bridges, railways, tunnels, dams, residential complexes, and commercial buildings, experience significant deterioration from the surrounding harsh environment. Traditional methods of visual inspection and non-destructive tests are generally undertaken to monitor and evaluate the structural health of the infrastructure.

Cross-view geo-localization (CVGL) aims to determine the capture location of street-view images by matching them with corresponding 2D maps, such as satellite imagery. While recent bird's eye view (BEV)-based methods have advanced this task by addressing viewpoint and appearance differences, the existing approaches typically rely solely on either OpenStreetMap (OSM) data or satellite imagery, limiting localization robustness due to single-modality constraints. This paper presents a novel CVGL method that fuses OSM data with satellite imagery, leveraging their complementary strengths to enhance localization robustness.

Brain tumors present a significant global health challenge, and their early detection and accurate classification are crucial for effective treatment strategies. This study presents a novel approach combining a lightweight parallel depthwise separable convolutional neural network (PDSCNN) and a hybrid ridge regression extreme learning machine (RRELM) for accurately classifying four types of brain tumors (glioma, meningioma, no tumor, and pituitary) based on MRI images. The proposed approach enhances the visibility and clarity of tumor features in MRI images by employing contrast-limited adaptive histogram equalization (CLAHE).

Antiretroviral therapy (ART) use and HIV suppression among people living with HIV (PLHIV) are critical for HIV control and prevention. Extreme restrictions on movement early during the COVID-19 pandemic in Uganda may have impeded the ability to initiate and sustain access to and use of ART. From our stepped-wedge cluster-randomized trial of an integrated PrEP and ART intervention for HIV-serodifferent couples at 12 ART clinics in Uganda, we identified participants who enrolled and had a 6-month post-ART initiation viral load measured before the beginning of the first COVID-19 lockdown (Period 1), participants whose enrollment and 6-month viral load measurement straddled pre-COVID and COVID lockdown times (Period 2), and participants whose enrollment and 6-month viral load were quantified entirely during COVID-19 (Period 3).
