Combination HIV Prevention Strategies in the Lisbon Cohort of Men who Have Sex with Men: A Longitudinal Cluster Analysis of Data from 2014 to 2021
This study aims to examine how HIV prevention tools were used and how they clustered together among men who have sex with men (MSM) testing at a community-based sexual health center in Lisbon, Portugal, from 2014 to 2021. We used data from 16,780 visits from adult cisgender MSM and had an HIV-negative test result at baseline in the Lisbon Cohort of MSM-an open, prospective cohort study conducted at CheckpointLX, a community-based sexual health ce…
Odyssey: A Spatial Data Infrastructure for Archaeology
Geospatial data acquisition methods like airborne LiDAR allow for obtaining large volumes of data, such as aerial and satellite imagery, which are increasingly being used in archaeology. As in other subjects, the ability to produce raw datasets far exceeds the capacity of domain experts to process and analyze them, but recent developments in image processing, Geographic Information Systems (GIS), Machine Learning (ML) and related technologies ena…
Automated Detection of Hillforts in Remote Sensing Imagery With Deep Multimodal Segmentation
Recent advancements in remote sensing and artificial intelligence can potentially revolutionize the automated detection of archaeological sites. However, the challenging task of interpreting remote sensing imagery combined with the intricate shapes of archaeological sites can hinder the performance of computer vision systems. This work presents a computer vision system trained for efficient hillfort detection in remote sensing imagery. Equipped w…
Nova Planta Do Castelo Velho De Safara: Integração De Dados Arqueológicos Com Topografia De Alta Resolução Derivada De Levantamento Drone-Lidar
Com este estudo apresenta-se uma nova perspectiva tridimensional do Castelo Velho de Safara (Moura), um dos grandes povoados muralhados da Idade do Ferro/período Romano Republicano existentes na linha do Rio Guadiana, criada a partir de um levantamento de alta resolução realizado com sensor LiDAR acoplado a um drone. O resultado obtido permitiu a definição detalhada da planta da muralha, o que implicou a revisão da superfície de ocupação, que ago…

An unusual coronoid fracture in a fragment of ulna recovered from the Prehistoric site of Buraca da Moira Rock Shelter (Boa Vista, Leiria)
In 2015, several disarticulated human skeletal remains were identified in the top layers of the prehistoric site of Buraca da Moira Rock Shelter (Boa Vista, Leiria), during the archaeological excavation carried out under the scope of the EcoPLis — Human Occupations in the Pleistocene Ecotones of the River Lis project. The recovery of chert, constiquartz and quartzite blanks, a schist plate, as well as adornments in bone and shell indicates a Late…
Changes in the exploitation dynamics of small terrestrial vertebrates and fish during the Pleistocene–Holocene transition in the SW Iberian Peninsula: A review
The Pleistocene–Holocene transition c. 11.5 ka cal. BP is associated with dramatic climatic changes. These events led to fundamental shifts in landscape and have, therefore, been seen as responsible for a major impact on the human ecological behavior of the last hunter–gatherers in the Western European territory. In the case of Iberian Peninsula, it is commonly assumed that these human ecological adaptations are reflected in the new settlement an…
Chronology of the Mesolithic occupation of the Muge valley, central Portugal: The case of Cabeço da Amoreira
Idade e uso de preservativo na iniciação sexual de adolescentes brasileiros
OBJETIVO: Analisar a idade e o uso do preservativo na iniciação sexual de adolescentes brasileiros em dois períodos: 1998 e 2005. MÉTODOS: Amostras representativas da população urbana brasileira foram entrevistadas em inquérito domiciliar por duas pesquisas, realizadas em 1998 e 2005. Dentre os entrevistados, 670 jovens (16 a 19 anos) sexualmente ativos foram selecionados para o estudo, 312 de 1998 e 358 de 2005. Para análise dos dados ponderados…
