Weak lensing galaxy cluster field reconstruction

Jean-Paul Richard Kneib, Mathilde Jauzac

In this paper, we compare three methods to reconstruct galaxy cluster density fields with weak lensing data. The first method called FLens integrates an inpainting concept to invert the shear field with possible gaps, and a multi-scale entropy denoising pr ...

Extending the Real Remoteness of Long-Range Brillouin Optical Time-Domain Fiber Analyzers

Luc Thévenaz, Sang Hoon Chin, Marcelo Alfonso Soto Hernandez

The real remoteness of a distributed optical fiber sensor based on Brillouin optical time-domain analysis is considerably extended in this paper using seeded second-order Raman amplification and optical pulse coding. The presented analysis and the experime ...

Normalized GNSS Interference Pattern Technique for Altimetry

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Miguel Angel Ribot Sanfelix, Mohammed Benjelloun

It is well known that reflected signals from Global Navigation Satellite Systems (GNSS) can be used for altimetry applications, such as monitoring of water levels and determining snow height. Due to the interference of these reflected signals and the motio ...

Tri-gate silicon nanowire transistors for ultra-low pH resolution and improved scalability

Enrico Accastelli

The scalability of on-chip analytical systems based on field-effect transistors as pH sensors is limited by the degradation of the signal to noise ratio when decreasing the device size. Nano-sized tri-gate transistors such as silicon nanowires and nanoribb ...

Performance evaluation of the emerging JPEG XT image compression standard

Touradj Ebrahimi

The upcoming JPEG XT is under development for High Dynamic Range (HDR) image compression. This standard encodes a Low Dynamic Range (LDR) version of the HDR image generated by a Tone-Mapping Operator (TMO) using the conventional JPEG coding as a base layer ...

On the selection of radiating elements for compact indoor massive-MIMO base stations

Julien Perruisseau-Carrier

Massive-multiple input multiple output (MIMO) was recently proposed as a key solution for improving the performance of multi-user MIMO in future cellular generations. The main paradigm in this novel MIMO technique is to use a very large number of antenna e ...

Phase-based manganese enhanced MRI, a new methodology to enhance brain cytoarchitectural contrast and study manganese uptake

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

Purpose As the magnetic susceptibility induced frequency shift increases linearly with magnetic field strength, the present work evaluates manganese as a phase imaging contrast agent and investigates the dose dependence of brain enhancement in comparison t ...
