Geographical origin identification of pure Sri Lanka tea infusions with electronic nose, electronic tongue and sensory profile analysis Geographical origin identification of pure Sri Lanka tea infusions with electronic nose, electronic tongue and sensory profile analysis  [registered users only]
In this study five Sri Lanka black teas were analyzed by electronic nose, electronic tongue and sensory panel. Data were analyzed with principle component analysis (PCA), linear discriminant analysis (LDA) and in case of sensory analysis with one-way ANOVA. The partial least square regression (PLS) was used to estimate the sensory attributes. [February 16, 2010]


Sniffing out the Tempranillo Sniffing out the Tempranillo 
Chemometrics and mass spectrometry can be used to classify wine according to geographic region. Proof of principle was undertaken with the new electronic nose carried out successfully with Tempranillo wines from Spain and Australia. [February 15, 2010]


A diagonal measure and a local distance matrix to display relations between objects and variables A diagonal measure and a local distance matrix to display relations between objects and variables  [registered users only]
The authors introduce two concepts to develop a method, where a proper change of rows and columns of a data matrix yields patterns of significant new information. By using their diagonal matrix measure and local distance matrix the similar objects were arranged close to each other in the data matrix and simultaneously the variables responsible for their similarity were collected close to the diagonal part defined by these objects.

Special Issue of Journal of Molecular Recognition:
Dynamics of Molecular Recognition
  [registered users only]
Molecular recognition is a key phenomenon in biology. It has been a long time since a static model like the 'lock-and-key principle' was the basis of the understanding of molecular recognition. Today complex dynamic models and calculations are used to better understand and the elucidation of these processes remains one of the major challenges for decades to come.

Martin Karplus (Harvard University and Université de Strasbourg) has been at the centre of modelling and computing complex and dynamic molecular recognition processes. It was therefore timely that the Journal of Molecular Recognition published a special issue on Dynamical Aspects of Molecular Recognition. The articles give a good introduction into the wide range of methods used to understand molecular recognition and helping to open new approaches in drug research.
