Reviews the book, Language, Music, and the Brain: A Mysterious Relationship by Michael A. Arbib (2013). For the researcher, or for anyone interested in research using a multidisciplinary approach to the problem of the interrelations between language, music, and the brain, this anthology is at the same time a rich “Handbook of...” and “A Companion to....” As such the book ought to be a priceless re
The paper presents results of a study on the use of the NOAA AVHRR data for desertification monitoring on a regional-global level. It is based on processing of the GIMMS 8 km global NDVI data set. Time series of annual integrated NDVI and standardized annual NDVI anomalies from the 1981-2003 periodic means were compared with a corresponding rainfall data set (i.e. 1981-2003) as well as a historica
A mathematical framework is introduced for optimization of antenna near-field imaging problems, based on the multipole expansion of the electromagnetic field, the Fisher information to quantify the quality of data and use of modern interior point convex optimization techniques. We consider the general problem of optimizing the measurement sensor allocation for parameter estimation in distributed s
Aromatic non-natural amino acids, the outstanding feature of which was the presence of several arms, were synthesised and their properties investigated. The amino acids were synthesised following a standard procedure starting with a Horner-Wadsworth-Emmons or a Heck reaction, which provided didehydroamino acids. Catalytic asymmetric hydrogenation produced the enantiopure amino acid precursors. The
The experience from electricity market reform in Sweden is reviewed and new approaches to promote improvements and investments in energy efficiency and renewable energy are discussed. On the first of January 1996 a new Swedish Electricity Act went into force, making it possible for consumers and retailers of electricity to choose between competing suppliers. Introducing competition fundamentally c
Professor Håkan Olsson, Lund has addressed the problems caused by patenting in the field of biotechnology. His article was triggered by patent protection acquired by the American company Myriad Genetics. According to HO, Myriad requires that analyses of blood to trace the occurrence of these genes should be carried out in the company’s American laboratories, at a significant cost. Profit is infrin
The paper shows how a synthetic gradient of a quadratic cost functioncan be used to monitor performance. The method requires a model of theclosed loop system. In the current paper this is obtained from therecommended tuning rule. The tuning rule requires a simple model of theprocess.The method is non-invasive, only closed loopdata from normal operation is used. By monitoring the gradient, informat
Observing that people who wish to engage in prosocial behavior are often presented with more than one means to the same end, we develop a theory in which agents may contribute to a single public good through a range of different activities. Our aim with this extension is twofold. First, we deliver positive results. Noting that effort on one activity has been argued to crowd out ("moral licensing")

Phototoxicity occurs when a substance is toxic only under the action of light, and can, depending on the mechanism of toxic action, be divided into type I and type II phototoxicity. Other types are sometimes recongnized, and sometimes toxicity occurs through more than one mechanism. Plants often use phototoxins for their defense. They may be harmful to man, but also exploited for medical treatment
