Two distinct promoter architectures centered on dynamic nucleosomes control ribosomal protein gene transcription

Felix Naef, Sebastian Maerkl, Jacques Rougemont, Nicolas Dénervaud, Marcel Geertz, Philippe Jacquet

In yeast, ribosome production is controlled transcriptionally by tight coregulation of the 138 ribosomal protein genes (RPGs). RPG promoters display limited sequence homology, and the molecular basis for their coregulation remains largely unknown. Here we ...

Modeling Discrete and Rhythmic Movements through Motor Primitives: A Review

Auke Ijspeert, Sarah Dégallier Rochat

Rhythmic and discrete movements are frequently considered separately in motor control, probably because different techniques are commonly used to study and model them. Yet, an increasing interest for a comprehensive model for movement generation requires t ...

Adaptive Oscillators with Human-in-the-Loop: Proof of Concept for Assistance and Rehabilitation

Auke Ijspeert, Jesse van den Kieboom, Renaud Ronsse

Most recent findings in robot-assisted therapy suggest that the therapy is more successful if the patient actively participates to the movement (“assistance-as-needed”). In the present contribution, we propose a novel approach for designing highly flexible ...

Pattern generators with sensory feedback for the control of quadruped locomotion

Auke Ijspeert, Ludovic Righetti

Central Pattern Generators (CPGs) are becoming a popular model for the control of locomotion of legged robots. Biological CPGs are neural networks responsible for the generation of rhythmic movements, especially locomotion. In robotics, a systematic way of ...

Movement generation using dynamical systems: a humanoid robot performing a drumming task

Auke Ijspeert, Ludovic Righetti, Sarah Dégallier Rochat

The online generation of trajectories in humanoid robots remains a difficult problem. In this contribution, we present a system that allows the superposition, and the switch between, discrete and rhythmic movements. Our approach uses nonlinear dynamical sy ...

A flexible motif search technique based on generalized profiles

Philipp Bucher

A flexible motif search technique is presented which has two major components: (1) a generalized profile syntax serving as a motif definition languaje; and (2) a motif search method specifically adapted to the problem of finding multiple instances of a mot ...

Characterization of the katG gene encoding a catalase-peroxidase required for the isoniazid susceptibility of Mycobacterium tuberculosis.

Stewart Cole, Ye Zhang

The isoniazid susceptibility of Mycobacterium tuberculosis is mediated by the product of the katG gene which encodes the heme-containing enzyme catalase-peroxidase. In this study, the chromosomal location of katG has been established and its nucleotide seq ...
