Empowerment : An Introduction
(Springer Nature Link, 2014)This book chapter is an introduction to and an overview of the information-theoretic, task independent utility function "Empowerment", which is defined as the channel capacity between an agent's actions and an agent's ... -

Elastic energy storage and release in white muscle from dogfish scyliorhinus canicula
(1999-01)The production of work by the contractile component (CC) and the storage and release of work in the elastic structures that act in series (the series elastic component, SEC) with the contractile component were measured ... -
Contraction with shortening during stimulation or during relaxation : how do the energetic costs compare?
(1998-10)White muscle fibres from dogfish were used to compare the energetic costs of shortening by fully active muscle and by relaxing muscle. The muscle preparation was tetanized for 0.6 s and shortened either during stimulation ... -
Heat production and oxygen consumption during metabolic recovery of white muscle fibres from the dogfish Scyliorhinus canicula
(2000-04)Oxygen consumption and heat production were measured during contraction and recovery of isolated, white muscle fibres from dogfish (Scyliorhinus canicula) at 19 degrees C. The contraction period consisted of 20 isometric ... -
Shortening during stimulation vs. during relaxation : How do the costs compare?
(1998)White muscle fibres from dogfish were used to investigate the energetic cost of shortening by fully active muscle and by relaxing muscle. The muscle preparation was tetanized for 0.6 s and shortened by 1 mm (about 15% L0) ... -
Isometric and isovelocity contractile performance of red muscle fibres from the dogfish Scyliorhinus canicula
(2002-06)Maximum isometric tetanic force produced by bundles of red muscle fibres from dogfish, Scyliorhinus canicula (L.), was 142.4+/-10.3 kN m(-2) (N=35 fibre bundles); this was significantly less than that produced by white ... -
Sustained performance by red and white muscle fibres from the dogfish Scyliorhinus canicula
(2010-06-01)The mechanical performance of red and white muscle fibres from dogfish was compared during a long series of contractions with sinusoidal movement or under isometric conditions at 12 degrees C (normal in vivo temperature). ... -
2,3-Butanedione monoxime increases speed of relaxation in single muscle fibres of frog
(2001-05)The effects of 2,3-butanedione monoxime (BDM) on intracellular Ca2+ transient and cross-bridge function were studied in frog single fibres from the anterior tibialis muscle of Rana temporaria (sarcomere length, 2.2 microm; ... -
The relationship between the intracellular Ca2+ transient and the isometric twitch force in frog muscle fibres
(1996-09)The calcium-sensitive fluorescent indicator fluo-3 was used to monitor the intracellular free calcium concentration ([Ca2+]i) during isometric twitches in twenty-nine single muscle fibres from the anterior tibialis muscle ... -
The high-force region of the force-velocity relation in frog skinned muscle fibres
(1993-07)The force-velocity relation has been studied during calcium-induced contracture of chemically skinned fibres from the semitendinosus muscle of Rana temporaria with special interest focused on the high-load region. The ... -
The effects of 2,3-butanedione monoxime (BDM) on the force-velocity relation in single muscle fibres of the frog
(1995-04)The effects of 2,3-butanedione monoxime (BDM) on the force-velocity relation were studied in single fibres from the anterior tibialis muscle of Rana temporaria (2.2 microns sarcomere length, temperature 1.9-2.4 degrees C). ... -
All Our Ancestors
(2014)All Our Ancestors is a British Council supported artist residency and collaborative exhibition by Simeon Nelson at the First Floor Gallery, Harare with Zimbabwean artist Moffat Takadiwa in 2014. It resulted in a 260 x 260 ... -
Moderate fatigue studied at great sarcomere lengths in frog single muscle fibres
(1994-10)Single fibres from the anterior tibialis muscle of Rana temporaria (temperature, 2-3 degrees C) were moderately fatigued at a prestretched sarcomere length (approximately 3.6 microns) by reducing the intervals between 2 s ... -
Changes in force and stiffness induced by fatigue and intracellular acidification in frog muscle fibres
(1990-05)1. Changes in force and stiffness were recorded simultaneously during 1 s isometric (fixed ends) tetani of single fibres isolated from the anterior tibialis muscle of Rana temporaria (temperature 1-3 degrees C; sarcomere ... -
Depression of tetanic force induced by loaded shortening of frog muscle fibres
(1993-07)1. Single fibres isolated from the anterior tibialis muscle of Rana temporaria were allowed to shorten against a high load during a 2.5-4.0 s fused tetanus (1-3 degrees C) and the maximum force produced at the short length ... -
Myofibrillar fatigue versus failure of activation during repetitive stimulation of frog muscle fibres
(1992-11)1. Single fibres isolated from the anterior tibialis muscle of Rana temporaria (temperature, 2-5 degrees C; sarcomere length, 2.10 microns) were fatigued using two separate protocols that led to different degrees of ... -
Variation in myoplasmic Ca2+ concentration during contraction and relaxation studied by the indicator fluo-3 in frog muscle fibres
(1994-07-01)1. The fluorescent dye fluo-3, in its permeant acetoxymethyl form, was used to monitor calcium transients during twitch and tetanus of single fibres isolated from the anterior tibialis muscle of Rana temporaria (2-5 degrees ...
