Coupled seismogenic geohazards in Alpine regions

Lyesse Laloui, Pierino Lestuzzi, Alessio Ferrari, Cyrill Silvan Baumann, Clotaire Michel, Fabrice Dupray, Amin Karbassi

COupled seismogenic GEohazards in Alpine Regions (COGEAR) is an interdisciplinary natural hazard project investigating the hazard chain induced by earthquakes. It addresses tectonic processes and the related variability of seismicity in space and time, ear ...

Innovative and low cost continuous evacuation of sediment through the intake structure using multiple jets at the reservoir bottom

Anton Schleiss, Giovanni De Cesare, Jolanda Maria Isabella Jenzer Althaus

Reservoir sedimentation is worldwide a significant long term problem and requires in view of the current mitigation measures an alternative and more sustainable solution. This challenge motivated the present study with the purpose to develop an alternative ...

Astrocyte-neuron lactate transport is required for long-term memory formation

We report that, in the rat hippocampus, learning leads to a significant increase in extracellular lactate levels that derive from glycogen, an energy reserve selectively localized in astrocytes. Astrocytic glycogen breakdown and lactate release are essenti ...

Neurobiological Mechanisms Involved in the Establishment and Maintenance of Dominance Hierarchies and its Modulation by Stress in Rats

Maria del Carmen Sandi Perez, Marjan Timmer

Stress can have a strong and long lasting effect on the establishment and maintenance of dominance hierarchies in rats. When two rats of a pair have not been stressed (non-stressed pair) before a first social encounter, they establish a dominance hierarchy ...

Nuclear protein phosphatase-1: an epigenetic regulator of fear memory and amygdala long-term potentiation

Johannes Gräff

Complex brain diseases and neurological disorders in human generally result from the disturbance of multiple genes and signaling pathways. These disturbances may derive from mutations, deletions, translocations or rearrangements of specific gene(s). Howeve ...

Long-Term Mechanical Reliability of Ceramic Thick-Film Circuits and Mechanical Sensors Under Static Load

Peter Ryser, Thomas Maeder, Caroline Jacq

Recently, high-strength zirconia-toughened alumina (ZTA) ceramic substrates have attracted interest, because they offer much improved mechanical properties over straight alumina, while maintaining advantages such as good thermal conductivity and chemical s ...

Longitudinal MR Assessment of Hypoxic Ischemic Injury in the Immature Rat Brain

Rolf Gruetter, Yohan Van de Looij

Extremely preterm infants commonly show brain injury with long-term structural and functional consequences. Three-day-old (P3) rat pups share some similarities in terms of cerebral development with the very preterm infant (born at 24-28 weeks of gestation) ...

In vivo Imaging Using Second-Harmonic Nanoparticles

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Thomas Jean Victor Marie Lanvin

We demonstrate second-harmonic nanoparticles as nanoprobes for long-term and in vivo imaging. The nanoparticles emitted a stable signal over five-hour continuous excitation and showed great contrast in a living mouse tail at 100 mu m depth. ...

Multiwalled Carbon-Nanotube-Functionalized Microelectrode Arrays Fabricated by Microcontact Printing: Platform for Studying Chemical and Electrical Neuronal Signaling

Michele Giugliano, Luca Gambazzi

A facile method is proposed for the deposition of multiwalled carbon nanotube (MWCNT) layers onto microelectrode arrays by means of a microcontact printing technique, leading to the fabrication of MEAs characterized by well defined electrical and morpholog ...

A history of spike-timing-dependent plasticity

Wulfram Gerstner, Henry Markram

How learning and memory is achieved in the brain is a central question in neuroscience. Key to today’s research into information storage in the brain is the concept of synaptic plasticity, a notion that has been heavily influenced by Hebb’s (1949) postulat ...
