Mathematical tools for analyzing the development of brain pathologies in children

Magnetic resonance imaging (MRI) enables medical doctors to obtain precise images of a patient’s structure and anatomy, and of the pathologies that may affect the patient’s brain. However, to analyze and interpret these complex images, radiologists need specific mathematical tools. While some tools exist for interpreting images of the adult brain, these tools are not […]

What is artificial intelligence?

Artificial intelligence (AI) is a hot topic. In late March, the French government organized a series of events dedicated to this theme, the most notable of which was the publication of the report “For a Meaningful Artificial Intelligence,” written by Cédric Villani, a mathematician and member of the French parliament. The buzz around AI coincides […]

Medicine for Materials

Did you know that materials have health problems too? To diagnose their structural integrity, researchers are increasingly using techniques similar to those used in the medical field for humans. X-rays, temperature checks and ultrasound imaging are just a few of the tools that help detection of abnormalities in parts. The advantage of these various techniques […]

Xenon instruments for long-term experiments

From the ancient gnomon that measured the sun’s height, to the Compton gamma ray observatory, the microscope, and large-scale accelerators, scientific instruments are researchers’ allies, enabling them to make observations at the smallest and largest scales. Used for both basic and applied research, they help test hypotheses and push back the boundaries of human knowledge. […]

Eikosim improves the dialogue between prototyping and simulation

Simulate. Prototype. Measure. Repeat. Developing an industrial part inevitably involves these steps. First comes the digital model. Then, its characteristics are assessed through simulation, after which, the first version of the part is built. The part must then be subject to mechanical stress to assess its resistance and be closely observed from every angle. The […]

The brain: seeing between the fibers of white matter

The principle behind diffusion imaging and tractography is exploring how water spreads through our brain in order to study the structure of neurons. Doctors can use this method to improve their understanding of brain disease. Pietro Gori, a researcher in image processing at Télécom ParisTech, has just launched a project called Neural Meta Tracts, funded […]

Climate change as seen from space

René Garello, IMT Atlantique – Institut Mines-Télécom [divider style=”normal” top=”20″ bottom=”20″] [dropcap]T[/dropcap]he French National Centre for Space Research has recently presented two projects based on greenhouse gas emission monitoring (CO2 and methane) using satellite sensors. The satellites, which are to be launched after 2020, will supplement measures carried out in situ. On a global scale, this […]
