Recent Developments in Data-Assisted Modeling of Flexible Proteins
PublicationMany proteins can fold into well-defined conformations. However, intrinsically-disordered proteins (IDPs) do not possess a defined structure. Moreover, folded multi-domain proteins often digress into alternative conformations. Collectively, the conformational dynamics enables these proteins to fulfill specific functions. Thus, most experimental observables are averaged over the conformations that constitute an ensemble. In this...

Wyznaczenie stref zagrożenia powodziowego w okresie remontu elektrowni wodnej Bielkowo na rzece Raduni
PublicationOd chwili uruchomienia elektrowni wodnej w jej najbliższym sąsiedztwie zmianie ulegają stosunki wodne. Przepływ wody skierowany zostaje do kanału zasilającego elektrowni, zaś w pierwotnym korycie rzeki zostaje często tylko przepływ biologiczny. Podczas eksploatacji elektrowni mogą zaistnieć sytuacje w których konieczne jest przywrócenie naturalnego układu wodnego. Okazuje się jednak, że pierwotne koryto uległo stopniowemu przystosowaniu...
