Estimation of Relative Position and Coordination of Mobile Underwater Robotic Platforms through Electric Sensing

Auke Ijspeert, Yannick Morel, Mathieu Porez

In the context of underwater robotics, positioning and coordination of mobile agents can prove a challenging problem. To address this issue, we propose the use of electric sensing, with a technique inspired by weakly electric fishes. In particular, the app ...

DCE-MRI using small-molecular and albumin-binding contrast agents in experimental carcinomas with different stromal content

Alessandro Daducci

OBJECTIVES: To compare DCE-MRI experiments performed using a standard small-molecular (Gd-DTPA) and an albumin-binding (MS-325) contrast agent in two carcinoma models with different stromal content. MATERIALS AND METHODS: DU-145 or BXPC-3 cancer cells were ...

Head Motion Detection Using FID Navigators

Rolf Gruetter, Tobias Kober, José Pedro Rebelo Ferreira Marques

This work explores a concept for motion detection in brain MR examinations using high channel-count RF coil arrays. It applies ultrashort (< 100 mu sec) free induction decay signals, making use of the knowledge that motion induces variations in these signa ...

Mn2+ Complexes with 12-Membered Pyridine Based Macrocycles Bearing Carboxylate or Phosphonate Pendant Arm: Crystallographic, Thermodynamic, Kinetic, Redox, and 1H/17O Relaxation Studies

Lothar Helm, Eva Jakab Toth

Mn2+ complexes represent an alternative to Gd3+ chelates which are widely used contrast agents in magnetic resonance imaging. In this perspective, the authors studied the Mn2+ complexes of two 12-membered, pyridine-contg. macrocyclic ligands bearing one pe ...

Hard x-ray Zernike microscopy reaches 30 nm resolution

Giorgio Margaritondo, Vincent Gajdosik

Since its invention in 1930, Zernike phase contrast has been a pillar in optical microscopy and more recently in x-ray microscopy, in particular for low-absorption-contrast biological specimens. We experimentally demonstrate that hard-x-ray Zernike microsc ...

Experimental Comparisons of 3D Reconstructed Pin-Power Distributions in Full-Scale BWR Fuel Assemblies

Rakesh Chawla, Flavio Dante Giust

In this paper, reconstructed local fission rates obtained with the two-group nodal diffusion program PRESTO-2, used at the Leibstadt Nuclear Power Plant (KKL) in Switzerland, are compared with experimental results and MCNPX calculations. The experimental f ...

Electrostatic torsional vertical flaps for reflective MEMS display

Nico de Rooij, Wilfried Noell, Fabio Jutzi

A new kind of high contrast, MEMS-based reflective display system is being developed. The system consists of light reflective flaps on an optically absorptive surface. The novelty is that the flaps are in vertical position at their rest state. They can be ...

Variational Enhancement And Denoising Of Flow Field Images

Michaël Unser, Ricard Delgado Gonzalo, Pouya Dehghani Tafti

In this work we propose a variational reconstruction algorithm for enhancement and denoising of flow fields that is reminiscent of total-variation (TV) regularization used in image processing, but which also takes into account physical properties of flow s ...
