Zero echo time MRI- only treatment planning for radiation therapy of brain tumors after resection

C. Boydev, B. Demol, David Pasquier, Hervé Saint-Jalmes, G. Delpon, N. Reynaert

Using magnetic resonance imaging (MRI) as the sole imaging modality for patient modeling in radiation therapy (RT) is a challenging task due to the need to derive electron density information from MRI and construct a so-called pseudo-computed tomography (pCT) image. We have previously published a...

Atomic-scale structure of the glassy Ge 2 Sb 2 Te 5 phase change material: A quantitative assessment via first-principles molecular dynamics

Assil Bouzid, Guido Ori, Mauro Boero, Evelyne Lampin, Carlo Massobrio

The amorphous structure of the phase change material Ge2Sb2Te5 (GST) has been the object of controversial structural models. By employing first-principles molecular dynamics within density functional theory, we are able to obtain quantitative agreement with experimental structural findings for the...

Top-down Approach for the Direct Synthesis, Patterning, and Operation of Artificial Micromuscles on Flexible Substrates

Ali Maziz, Cedric Plesse, Caroline Soyer, Eric Cattan, Frederic Vidal

Recent progress in the field of microsystems on flexible substrates raises the need for alternatives to the stiffness of classical actuation technologies. This paper reports a top-down process to microfabricate soft conducting polymer actuators on substrates on which they ultimately operate. The...

Interview: Joseph Agassi

Mauro Condé, Raffaele Pisano, Michael Segre

Joseph Agassi is an Israeli scholar born in Jerusalem on May 7, 1927. He has many books and articles published contributing to the fields of logic, scientific method, foundations of sciences, epistemology and, most importantly for this Journal, in the historiography of science. He studied with Karl...
