Toward 30-gram Autonomous Indoor Aircraft: Vision-based Obstacle Avoidance and Altitude Control

Dario Floreano, Jean-Christophe Zufferey

We aim at developing autonomous micro-flyers capable of navigating within houses or small built environments. The severe weight and energy constraints of indoor flying platforms led us to take inspiration from flying insects for the selection of sensors, s ...

Optic-flow-based steering and altitude control for ultra-light indoor aircraft

Dario Floreano, Jean-Christophe Zufferey

Our goal is to demonstrate the ability of bio-inspired techniques to solve the problem of piloting an autonomous 40-grams aircraft within textured indoor environments. Because of severe weight and energy constraints, inspiration has been taken from the fly ...

Adipose tissue expression of the lipid droplet-associating proteins S3-12 and perilipin is controlled by peroxisome proliferator-activated receptor-gamma

Johan Auwerx, Kristina Schoonjans

In a systematic search for peroxisome proliferator-activated receptor-gamma (PPAR-gamma) target genes, we identified S3-12 and perilipin as novel direct PPAR-gamma target genes. Together with adipophilin and tail-interacting protein of 47 kDa, these genes ...

A combined RSA and FE study of the implanted proximal tibia: correlation of the post-operative mechanical environment with implant migration

Kai Johnsson

There is strong evidence to suggest that inducible displacements, migration and implant loosening are closely related to the initial mechanical environment of the implanted tibia. If this is true, then it should be possible to predict the likelihood of imp ...

Compensation by the muscle limits the metabolic consequences of lipodystrophy in PPAR gamma hypomorphic mice

Johan Auwerx

Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a nuclear receptor, which controls adipocyte differentiation. We targeted with homologous recombination the PPAR gamma 2-specific exon B, resulting in a white adipose tissue knockdown of PPAR ...

Mobility related physical and functional losses due to aging and disease - a motivation for lower limb exoskeletons

Background Physical and functional losses due to aging and diseases decrease human mobility, independence, and quality of life. This study is aimed at summarizing and quantifying these losses in order to motivate solutions to overcome them with a special f ...

Activation of peroxisome proliferator-activated receptor delta induces fatty acid beta-oxidation in skeletal muscle and attenuates metabolic syndrome

Johan Auwerx

In this study, we defined the role of peroxisome proliferator-activated receptor beta/delta (PPARdelta) in metabolic homeostasis by using subtype selective agonists. Analysis of rat L6 myotubes treated with the PPARdelta subtype-selective agonist, GW501516 ...

SRC-1 and TIF2 control energy balance between white and brown adipose tissues

Johan Auwerx

We have explored the effects of two members of the p160 coregulator family on energy homeostasis. TIF2-/- mice are protected against obesity and display enhanced adaptive thermogenesis, whereas SRC-1-/- mice are prone to obesity due to reduced energy expen ...

Gait-dependent integration of neck muscle afferent input

Grégoire Courtine

We investigated the integration of neck muscle afferents during walking and running. Subjects walked or ran straight ahead, with or without an additional mass (20% of body weight). They performed all trials without vibration and with continuous vibration ( ...

Optimal weights of evidence with bounded influence

Stephan Morgenthaler, Robert Staudte

A fundamental statistical problem is to indicate which of two hypotheses is better supported by the data. Statistics designed for this purpose are called weight of evidence. In this paper we study the problem of robust weights of evidence, optimal in their ...
