Analysing six types of protein-protein interfaces.
Non-covalent residue side-chain interactions occur in many different types of proteins and facilitate many biological functions. Are these differences manifested in the sequence compositions and/or the residue-residue contact preferences of the interfaces? Previous studies analysed small data sets and gave contradictory answers. Here, we introduced a new data-mining method that yielded the larg...
متن کاملSix Generic Types of Information Systems Evaluation
The aim of this paper is to contribute to the decision of how to perform evaluation depending on the evaluation context. Three general strategies of how to perform evaluation together with two general strategies of what to evaluate are identified. From the three “how-strategies” and the two “what-strategies” we derive a matrix consisting of six generic types of evaluation. Each one of the six t...

kinds of research that can be conducted. Please keep in mind as you read this that it was written by and for social researchers, who normally are very interested in studying people and the factors (variables) that affect people. As an engineer, you are equally likely, perhaps even more likely, to be interested in studying devices, materials, hardware, new techniques, and so on... These kinds of...
