Professional cleaning and safe social distance monitoring are often considered as demanding, time-consuming, repetitive, and labor-intensive tasks with the risk of getting exposed to the virus. Safe s…
Over the past few years, automatic recognition of human interactions has drawn significant attention from researchers working in the field of Artificial Intelligence (AI). And feature extraction is on…
COVID-19 pandemic has affected the population worldwide, evidencing new challenges and opportunities for several kinds of emergent and existing technologies. Social Assistive Robotics could be a poten…
In 2020, Brazil was the leading country in COVID-19 cases in Latin America, and capital cities were the most severely affected by the outbreak. Climates vary in Brazil due to the territorial extension…
The aim of this systematic review is to identify recent digital technologies used to detect early signs of autism spectrum disorder (ASD) in preschool children (i.e., up to six years of age). A …
Oscillations in the higher frequency range are closely related to regional brain hemodynamic changes. Here we investigated this neurovascular coupling in humans in response to electrical stimulation o…
Anopheles gambiae s.1. and An. funestus were sampled for Plasmodium spp. ookinetes in two P. falciparum-endemic sites in western Kenya. Since the ookinete is a transitional stage of short duration, oc…
The impact of basic military training (BMT) on recruit physical performance is well described. However, initial employment training (IET), the period immediately after BMT, is the final preparatory st…
A theoretical formulation for the profile of the integrated backscatter coefficient (IBC) is derived. This new formulation is based on a theoretical treatment by Chen et al. [1]. It includes correctio…
A method is described to determine the total retinal blood flow. Intravenous fluorescence angiography is the clinical procedure used, together with digital image processing methods. Our system consist…
Radiation therapy produces Cherenkov optical emission in tissue, and this light can be utilized to activate molecular probes. The feasibility of sensing luminescence from a tissue molecular oxygen sen…
Stereology applied on histological sections is the 'gold standard' for obtaining quantitative information on cancellous bone structure. Recent advances in micro computed tomography (microCT) have made…
The study aimed to assess the level of correlation between muscle-tendon unit (MTU) stiffness and mechanomyogram (MMG) signal amplitude of the human gastrocnemius medialis muscle, both before and afte…
INTRODUCTION: Diffusion Weighted Imaging (DWI), which is based on Echo Planar Imaging (EPI) protocols, is becoming increasingly important for neurosurgical applications. However, its use in this conte…
In this work, a number of important issues associated with fast spin echo (FSE) imaging of the human brain at 4.7 T are addressed. It is shown that FSE enables the acquisition of images with high reso…
Flow phantoms have been used to investigate and quantify three-dimensional power Doppler data but this is the first study to use the in vitro, dual perfused, placental perfusion model. We used this mo…
Electrical potentials were recorded from the cornea of the human eye in response to the onset and offset of square-wave stripe patterns varying in spatial frequency, luminance and contrast. Under high…
The lymphatic stomata in the pelvic peritoneum of human fetuses and mature mice were initially observed and studied quantitatively by using computer image processing (C.I.P.) attached to a scanning el…
Somatostatin in human pancreatic juice collected during endoscopic retrograde cholangiopancreatography following secretin injection was determined by RIA. The mean immunoreactive somatostatin (IRS) l…
