December 2024

Medical School, São Paulo State University Julio de Mesquita Filho, Av. Prof. Mário Rubens Guimarães Montenegro, S/N, UNESP Campus de Botucatu, Botucatu, SP, CEP: 18618687, Brazil.

Aim: CT images can identify structural and opacity alterations of the lungs while nuclear medicine's lung perfusion studies show the homogeneity (or lack of) of blood perfusion on the organ. Therefore, the use of SPECT/CT in lung perfusion scintigraphies can help physicians to assess anatomical and functional alterations of the lungs and to differentiate between acute and chronic disease.

Objective: To develop a computer-aided methodology to quantify the total global perfusion of the lungs via SPECT/CT images and to compare these results with parenchymal alterations obtained in CT images.

Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, CHU Sainte-Justine, Montreal University, Québec, Canada.

Article Synopsis
  • - The study focuses on the complications in monochorionic (MC) twin pregnancies, particularly twin-twin transfusion syndrome (TTTS) and selective intrauterine growth-restriction (sIUGR), which can affect fetal heart function due to imbalanced blood flow and increased placental resistance.
  • - Objectives include analyzing umbilical, ductal, and aortic measurements to distinguish between these complications and improve understanding of their physiological impacts on the fetuses.
  • - Findings from 113 pregnancies reveal specific Doppler indices (like ISI and UAPI) that vary between uncomplicated MC twins and those with sIUGR or TTTS, indicating different cardiac and placental responses to these conditions.

Current intervertebral disc finite element models are hard to validate since they describe multi-physical phenomena and contain a huge number of material properties. This work aims to simplify numerical validation/identification studies by prioritizing the sensitivity of intervertebral disc behavior to mechanical properties. A 3D fiber-reinforced hyperelastic model of a C6-C7 intervertebral disc is used to carry out the parametric study.

Université Clermont Auvergne, UMR 6602, Pascal Institute, Endoscopy and Computer Vision Group, University Hospital of Clermont-Ferrand, CHU Clermont-Ferrand, Gynecological Surgery, Clermont-Ferrand, France.

Despite the widely-known effects of air pollution, pollutants exposure surrounding pregnancy and the risk for autism spectrum disorder (ASD) in newborns remains controversial. The purpose of our study was to carry out a systematic review and meta-analyses of the risk of ASD in newborns following air pollution exposure during the perinatal period (preconception to second year of life). The PubMed, Cochrane Library, Embase and ScienceDirect databases were searched for articles, published up to July 2020, with the keywords "air pollution" and "autism".

To demonstrate and describe fetal head molding and brain shape changes during delivery, we used three-dimensional (3D) magnetic resonance imaging (MRI) and 3D finite element mesh reconstructions to compare the fetal head between prelabor and the second stage of labor. A total of 27 pregnant women were examined with 3D MRI sequences before going into labor using a 1 Tesla open field MRI. Seven of these patients subsequently had another set of 3D MRI sequences during the second stage of labor.

Active inference is a general framework for perception and action that is gaining prominence in computational and systems neuroscience but is less known outside these fields. Here, we discuss a proof-of-principle implementation of the active inference scheme for the control or the 7-DoF arm of a (simulated) PR2 robot. By manipulating visual and proprioceptive noise levels, we show under which conditions robot control under the active inference scheme is accurate.

Balancing habitual and deliberate forms of choice entails a comparison of their respective merits-the former being faster but inflexible, and the latter slower but more versatile. Here, we show that arbitration between these two forms of control can be derived from first principles within an Active Inference scheme. We illustrate our arguments with simulations that reproduce rodent spatial decisions in T-mazes.

To study human movement generation, as well as to develop efficient control algorithms for humanoid or dexterous manipulation robots, overcoming the limits and drawbacks of inverse-kinematics-based methods is needed. Adequate methods must deal with high dimensionality, uncertainty, and must perform in real time (constraints shared by robots and humans). This paper introduces a Bayesian filtering method, hierarchically applied in the operational and joint spaces to break down the complexity of the problem.

Models of implicit stereotypes (e.g., association of male with math or female with language) usually explain the faster responses observed for stereotype-congruent trials in the Implicit Association Test (IAT) by requiring a fundamental opposition between the male and female concepts (or math-language), limiting the decision-making dynamics to abstract dimensions.

How active perception and attractor dynamics shape perceptual categorization: a computational model.

Neural Netw

December 2014

Istituto di Scienze e Tecnologie della Cognizione - CNR, Via S. Martino della Battaglia, 44 - 00185 Rome, Italy. Electronic address:

We propose a computational model of perceptual categorization that fuses elements of grounded and sensorimotor theories of cognition with dynamic models of decision-making. We assume that category information consists in anticipated patterns of agent-environment interactions that can be elicited through overt or covert (simulated) eye movements, object manipulation, etc. This information is firstly encoded when category information is acquired, and then re-enacted during perceptual categorization.
