Addressable Current Reference Array with 170dB Dynamic Range

Configurable high-performance bias current reference circuits are useful in complex mixed-signal chips. This paper presents the design of a configurable current reference array with ultra wide dynamic range (DR). A coarse-fine architecture using octal coar ...

In-situ actuated gap reduction and clogging-free apertures for quasi-dynamic stencil lithography

Jürgen Brugger, Andreea Veronica Savu, Shenqi Xie

We demonstrate a high-resolution implementation of quasi-dynamic stencil lithography based on the integration of a micro-hotplate on the stencil membrane. The stencil design has been tailored so that the thermally actuated membrane reduces the gap between ...

High Time-Resolved Cardiac Functional Imaging Using Temporal Regularization for Small Animal on a Clinical 3T Scanner

Dimitri Nestor Alice Van De Ville, Jean-Noël Hyacinthe

Accurate assessment of mice cardiac function with magnetic resonance imaging is essential for longitudinal studies and for drug development related to cardiovascular diseases. Whereas dedicated small animal MR scanners are not readily available, it would b ...

Liquid-Quench Sampling System for the Analysis of Gas Streams from Biomass Gasification Processes. Part 1: Sampling Noncondensable Compounds

Christian Ludwig, Tilman J. Schildhauer

In biomass gasification plants and related research units, on-line analysis of noncondensable compounds (H-2, CO, CO2, CH4, and light hydrocarbons) and condensable compounds (water, tars, etc.) is desired. Long-duration on-line measurements are often a cha ...

Subjective quality evaluation of the upcoming HEVC video compression standard

Touradj Ebrahimi, Francesca De Simone, Philippe Hanhart, Martin Rerabek

High Efficiency Video Coding (HEVC) is the latest attempt by ISO/MPEG and ITU-T/VCEG to define the next generation compression standard beyond H.264/MPEG-4 Part 10 AVC. One of the major goals of HEVC is to provide efficient compression for resolutions beyo ...

Assessing the benefits of focal pair cryo-electron tomography

Henning Paul-Julius Stahlberg

Cryo electron tomography provides nanometer-scale information on biological matter preserved in a close-to native state. The resolution of tomograms and structures resolved by sub-tomogram averaging is typically limited by the contrast transfer function of ...

Mapping molecular statistics with balanced super-resolution optical fluctuation imaging (bSOFI)

Theo Lasser, Marcel Leutenegger, Noelia Laura Bocchio, Corinne Berclaz, Claudio Dellagiacoma, Stefan Geissbuehler

Super-resolution optical fluctuation imaging (SOFI) achieves 3D super-resolution by computing temporal cumulants or spatio-temporal cross-cumulants of stochastically blinking fluorophores. In contrast to localization microscopy, SOFI is compatible with wea ...

A High–Performance Parallel Implementation of the Chambolle Algorithm

David Atienza Alonso, Abdulkadir Akin, Ivan Beretta, Alessandro Antonio Nacci

The determination of the optical flow is a central problem in image processing, as it allows to describe how an image changes over time by means of a numerical vector field. The estimation of the optical flow is however a very complex problem, which has be ...

Characterisation of Living Matter Using Advanced Spectroscopy Techniques

Markus Bonda

In the context of an ageing society neurodegenerative disease have become more and more frequent among humans. Opposing the benefits of a longer life, these diseases have thus triggered research on neurons and how they interact with each other. In vitro as ...
