Versatile method employing basic techniques of genetic engineering to study the ability of low molecular weight compounds to bind covalently with DNA in cell free systems.
PublikacjaMechanizm działania większości leków przeciwnowotworowych oraz związków rakotwórczych polega na ich kowalencyjnym wiązaniu z DNA. Poziom tego wiązania jest zazwyczaj bardzo niski, co powoduje, że potrzebne są niezwykle czułe metody aby kowalencyjna modyfikacja mogła być w ogóle wykryta. My podjęliśmy próbę zastosowania w tym celu prostych, szybkich i sprawdzonych technik inżynierii genetycznej: metody PCR do uzyskania fragmentu...

Trustworthiness and Subversion in Large Service- Oriented Multi-Agent Systems under Virtual Anonymity and Blind Provider Selection
PublikacjaTo promote honest service provision in multi-agent systems, a Computational Trustworthiness and Rating scheme collects service ratings and computes agents' trustworthiness levels (TLs). Studies of existing schemes fail to reflect closed-loop dynamics of TLs arising from the mutual influence of agents' behavior and TLs, and to capture relevant properties. Recent simulative and analytical models produce results tied to a particular...

Recent advances in rapid multiobjective optimization of expensive simulation models in microwave and antenna engineering by Pareto front exploration
PublikacjaPractical engineering design problems are inherently multiobjective, that is, require simultaneous control of several (and often conflicting) criteria. In many situations, genuine multiobjective optimization is required to acquire comprehensive information about the system of interest. The most popular solution techniques are populationbased metaheuristics, however, they are not practical for handling expensive electromagnetic...
