Predicting visual stimuli from cortical response recorded with widefield imaging in a mouse

Optic nerve stimulation holds great potential for visual prostheses. Its effectiveness depends on the stimulation protocol, which can be optimized to achieve cortical activation similar to that evoked in response to visual stimuli. To identify a target cor ...

Improving Railway Track Coverage with mmWave Bridges: A Measurement Campaign

Andreas Peter Burg, Adrian Schumacher, Ruben Merz

Bringing cellular capacity into modern trains is challenging because they act as Faraday cages. Building a radio frequency (RF) corridor along the railway tracks ensures a high signal-to-noise ratio and limits handovers. However, building such RF corridors ...

Compressed sensing with signal averaging for improved sensitivity and motion artifact reduction in fluorine-19 MRI

Tobias Kober, Tom Hilbert, Jérôme Yerly, Ruud van Heeswijk, Elena Najdenovska

Fluorine-19 (F-19) MRI of injected perfluorocarbon emulsions (PFCs) allows for the non-invasive quantification of inflammation and cell tracking, but suffers from a low signal-to-noise ratio and extended scan time. To address this limitation, we tested the ...

Wide-field time-gated phasor analysis of visible fluorescence through highly scattering medium

Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü

Fluorescence sensing is an invaluable research tool in life science and biomedical imaging. Despite its major use and advantages, it mainly remains a tool for in vitro studies since exist fluorophores mainly absorb and emit light in the visible region, in ...

TDCOSMO II. Six new time delays in lensed quasars from high-cadence monitoring at the MPIA 2.2m telescope

Frédéric Courbin, Martin Raoul Robert Millon, Eric Gérard Guy Paic, Cameron Alexander Campbell Lemon, Sun Hee Kim, Hung-Hsu Chan, Vivien François Bonvin, Karina Alexandra Rojas Olate, Adriano Agnello

We present six new time-delay measurements obtained from Rc-band monitoring data acquired at the Max Planck Institute for Astrophysics (MPIA) 2.2m telescope at La Silla observatory between October 2016 and February 2020. The lensed quasars HE0047 1756, WG0 ...

A CMOS Analog Front-End for Implantable Pulmonary Artery Pressure Monitoring System

Marco Mattavelli, Catherine Dehollain, Diego Ruben Barrettino, Kerim Türe, Mustafa Besirli

This paper presents an energy-efficient analog front-end circuit to monitor the pulmonary artery pressure (PAP) with piezoresistive pressure sensors. A low-power capacitively-coupled instrumentation amplifier (CCIA) is developed in order to boost the ampli ...
