Colonialism, Justice and the Rule of Law: A Southern African and Australian Narrative

Colonialism has had a huge impact upon the legal systems of countries around the world. The historical impact of the British Empire can still be felt today in countries as diverse as Australia and South Africa. This effect is explored in both these countries, both in its historical form of racial discrimination, as well as the modern consequences of this colonial past. This article analyses how formal conceptions of the Rule of Law and legal certainty can undermine efforts to achieve justice for past historical wrongs. Examples of this are found in the Aboriginal land rights litigation in Australia, as well as litigation under the Alien Tort Statute in the United States of America

Variational Perturbation Theory for Markov Processes

We develop a convergent variational perturbation theory for conditional probability densities of Markov processes. The power of the theory is illustrated by applying it to the diffusion of a particle in an anharmonic potential.Comment: Author Information under http://www.physik.fu-berlin.de/~kleinert/institution.html Latest update of paper also at http://www.physik.fu-berlin.de/~kleinert/33

Conformational Mechanics of Polymer Adsorption Transitions at Attractive Substrates

Conformational phases of a semiflexible off-lattice homopolymer model near an attractive substrate are investigated by means of multicanonical computer simulations. In our polymer-substrate model, nonbonded pairs of monomers as well as monomers and the substrate interact via attractive van der Waals forces. To characterize conformational phases of this hybrid system, we analyze thermal fluctuations of energetic and structural quantities, as well as adequate docking parameters. Introducing a solvent parameter related to the strength of the surface attraction, we construct and discuss the solubility-temperature phase diagram. Apart from the main phases of adsorbed and desorbed conformations, we identify several other phase transitions such as the freezing transition between energy-dominated crystalline low-temperature structures and globular entropy-dominated conformations.Comment: 13 pages, 15 figure

A Transport Analysis of the BEEM Spectroscopy of Au/Si Schottky Barriers

A systematic transport study of the ballistic electron emission microscopy (BEEM) of Au/Si(100) and Au/Si(111) Schottky barriers for different thicknesses of the metal layer and different temperatures is presented. It is shown that the existing experimental data are compatible with a recently predicted bandstructure-induced non-forward electron propagation through the Au(111) layer.Comment: 5 pages, Latex-APS, 1 postscript figure, http://www.icmm.csic.es/Pandres/pedro.htm.

Microcanonical entropy inflection points: Key to systematic understanding of transitions in finite systems

We introduce a systematic classification method for the analogs of phase transitions in finite systems. This completely general analysis, which is applicable to any physical system and extends towards the thermodynamic limit, is based on the microcanonical entropy and its energetic derivative, the inverse caloric temperature. Inflection points of this quantity signal cooperative activity and thus serve as distinct indicators of transitions. We demonstrate the power of this method through application to the long-standing problem of liquid-solid transitions in elastic, flexible homopolymers.Comment: 4 pages, 3 figure

Thickness-dependent secondary structure formation of tubelike polymers

By means of sophisticated Monte Carlo methods, we investigate the conformational phase diagram of a simple model for flexible polymers with explicit thickness. The thickness constraint, which is introduced geometrically via the global radius of curvature of a polymer conformation, accounts for the excluded volume of the polymer and induces cooperative effects supporting the formation of secondary structures. In our detailed analysis of the temperature and thickness dependence of the conformational behavior for classes of short tubelike polymers, we find that known secondary-structure segments like helices and turns, but also ringlike conformations and stiff rods are dominant intrinsic topologies governing the phase behavior of such cooperative tubelike objects. This shows that the thickness constraint is indeed a fundamental physical parameter that allows for a classification of generic polymer structures

NESTMOD: The NetMod-NEST Interface

NESTMOD is a combined analytical modeling and simulation tool, based on the existing tools NetMod and NEST. It provides both transient and steady-state response statistics from models of interconnected local area networks that can execute at any level of detail desired. This gives users the potential to model both networks of extremely large scope (hundreds of thousands of nodes), and to look at great detail for any combination of the ISO layers. This paper describes the interface implementation, and presents an example to illustrate the potential power of the tool.http://deepblue.lib.umich.edu/bitstream/2027.42/107970/1/citi-tr-91-7.pd

Okuläre Pulsamplitude als biometrischer Messwert in der Glaukomdiagnostik

Zusammenfassung: Hintergrund: Die dynamische Konturtonometrie (DCT) ermöglicht direkte transkorneale Messungen des Augeninnendrucks und der okulären Pulsamplitude (OPA). Ziel dieser Studie war es, herauszufinden, ob die OPA als biometrischer Messwert Aussagen über verschiedene Glaukomformen erlaubt. Patienten und Methoden: Es wurden 441 Augen von 222Patienten in die Studie aufgenommen. Zur Druckmessung dienten die DCT und ein Applanationstonometer nach Goldmann. Ergebnisse: Die mittlere OPA betrug 3,1±1,4mmHg. Augen mit okulärer Hypertension (3,6±1,3mmHg) zeigten signifikant höhere Werte als gesunde Augen (3,1±1,4mmHg) und solche mit Niederdruckglaukom (2,9±1,4mmHg). Nach erfolgreicher Trabekulektomie wurden signifikant tiefere Werte (2,4±1,3mmHg) als bei Gesunden gemessen. Schlussfolgerung: Die OPA scheint diverse Formen des Glaukoms zu charakterisieren, könnte aber auch direkt von der Höhe des Augendrucks abhängen. Es muss weiter abgeklärt werden, ob sie einen prädiktiven Faktor in der Diagnose und der Verlaufsbeurteilung des Glaukoms darstell
