Structural and functional brain imaging using extended-focus optical coherence tomography and microscopy

Paul James Marchand

Neuroimaging techniques aim at revealing the anatomy and functional organisation of cerebral structures. Over the past decades, functional magnetic resonance imaging (fMRI) has revolutionized our understanding of human cerebral physiology through its abili ...

Neuronal morphologies: the shapes of thoughts

Lida Kanari

The mammalian brain, one of the most fascinating systems in nature, is a complex biological structure that has kept scientists busy for over a century. Many of the brain's mysteries have been unraveled due to the enormous efforts of the scientific communit ...

Comprehensive Morpho-Electrotonic Analysis Shows 2 Distinct Classes of L2 and L3 Pyramidal Neurons in Human Temporal Cortex

Lida Kanari, Idan Segev, Guy Antoine Atenekeng Kahou, Guy Eyal, Yair Deitcher

There have been few quantitative characterizations of the morphological, biophysical, and cable properties of neurons in the human neocortex. We employed feature-based statistical methods on a rare data set of 60 3D reconstructed pyramidal neurons from L2 ...

Tuning growth direction of catalyst-free InAs(Sb) nanowires with indium droplets

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Martin George Friedl, Heidi Andrea Potts, Nicholas Paul Morgan

The need for indium droplets to initiate self-catalyzed growth of InAs nanowires has been highly debated in the last few years. Here, we report on the use of indium droplets to tune the growth direction of self-catalyzed InAs nanowires. The indium droplets ...

Influencing axon regeneration after spinal cord injury

Mark Andrew Anderson

Spinal cord injury (SCI) results in a severing of axonal connections that leads to permanent sensorimotor deficits. In cases of incomplete injury, rehabilitation paradigms have been reported to be successful in improving behavioral outcome in humans with S ...

Effect of fiber orientation on the in-plane tensile response of UHPFRC reinforcement layers

Eugen Brühwiler, Emmanuel Denarié, Maléna Bastien Masse

The application on existing Reinforced Concrete (RC) slabs of cast-on site Ultra-High Performance Fiber Reinforced cement-based Composite UHPFRC) layers is a very efficient reinforcement technique, currently spreading. For the design of these tensile reinf ...

Framework for efficient synthesis of spatially embedded morphologies

Lida Kanari, Julian Charles Shillcock, Liesbeth Maria L Vanherpe, Guy Antoine Atenekeng Kahou, Juan Pablo Palacios

Many problems in science and engineering require the ability to grow tubular or polymeric structures up to large volume fractions within a bounded region of three-dimensional space. Examples range from the construction of fibrous materials and biological c ...

A Model Predictive Control scheme with Ultimate Bound for Economic Optimization

Colin Neil Jones, Andrea Alessandretti

This paper presents a Model Predictive Control (MPC) scheme for nonlinear continuous-time systems where an economic stage cost, which is not a measure of the distance to a desired set point, is combined with a classic stabilizing stage cost. The associated ...

Controlling Mesopore Size and Processability of Transparent Enzyme-Loaded Silica Films for Biosensing Applications

Heinrich Hofmann, Bernard Wenger, Oswaldo Javier Pérez Anguiano, Raphaël Pugin, Emmanuel Scolan

Silica-based nanoporous thin films including large mesopores are relevant as enzyme supports for applications in biosensing. The diffusion and immobilization of large biomolecules such as enzymes in such porous films require the presence of large mesopores ...

Influence of Zinc Anisotropy on Solidification Microstructures: Experimental Results and Phase-Field Simulations

Alexandre Durussel

Due to a distortion of its hexagonal unit cell along the c-axis compared to hexagonal-close-packed metals (c/a = 1.856 instead of 1.633), zinc is characterised by a large anisotropy of its solid-liquid interfacial energy. While previous studies have focuse ...
