Commercial vs. Product Placement: a study with young children
Omar, Ismael MahomedThe aim of this study is to investigate how young children (5-7 years old) are affected by commercials and product placements regarding the detection of advertising content, brand awareness and brand choice. We also wanted to study the relation of those variables with age (children before and after entering into primary school) and gender. For it, 75 children were presented to a controlled experimental approach...

Enhancing lysosome function via TFEB activation reduces lipofuscin-like granule...
Falcão, Ana S.; Lopes-da-Silva, Mafalda; Antas, Pedro; Escrevente, Cristina; Pedro, Margarida; Felgueiras, Beatriz; Caires, Beatriz; Coelho, RitaAge-related macular degeneration (AMD) is the most common blinding disease in the western world and is currently incurable. Although the exact causes of AMD are not clear, the primary origin of pathology appears to be the aged retinal pigment epithelium (RPE) exhibiting signs of lysosomal dysfunction and oxidative damage. RPE is responsible for the daily digestion of photoreceptor outer segments (POS), imposing...

Improving UAV-derived nearshore bathymetry using geospatial machine learning
Dias, Telmo; Carvalho, Paulo; Costa, Ana Cristina; Baptista, Márcia L.Accurate coastal bathymetry is essential for ocean science and blue economy applications. However, nearshore regions remain under-surveyed due to dynamic environmental conditions and the limitations of traditional multibeam echosounders (MBES). This study presents a framework that integrates high-resolution unmanned aerial vehicle (UAV) multispectral imagery with geospatial machine learning to address spatial v...
Automated Detection of Contaminants: Using Computer Vision for Food Quality Con...
Carvalho, Miguel MartinsThe presence of foreign objects in food processing lines poses significant risks to consumer safety, product quality, and regulatory compliance. Traditional inspection methods such as manual visual checks or metal detectors are limited in their ability to detect non-metallic con- taminants like plastic, wood, or glass, especially when mixed with vegetable products. In re- sponse to this challenge, this work pro...
Os efeitos das máquinas de propaganda na cobertura de guerra: o caso dos enviad...
Furtado, Mariana GonçalvesEm 2025, o número de jornalistas mortos atingiu o valor mais elevado desde 2019. A tendência crescente de mortes em contextos de guerra reforça a ideia de que, mesmo com os avanços tecnológicos e as salvaguardas jurídicas existentes, ser repórter de guerra continua a representar uma das missões mais arriscadas da profissão. Nos conflitos contemporâneos, que no atual panorama digital, se tornaram, acima de tudo,...
