The replication crisis [a] is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method , [ 2 ] such failures undermine the credibility of theories building on them and potentially call ...
Optimistic replication, also known as lazy replication, [1] [2] is a strategy for replication, in which replicas are allowed to diverge. [ 3 ] Traditional pessimistic replication systems try to guarantee from the beginning that all of the replicas are identical to each other, as if there was only a single copy of the data all along.
Example of direct replication and conceptual replication. There are two main types of replication in statistics. First, there is a type called “exact replication” (also called "direct replication"), which involves repeating the study as closely as possible to the original to see whether the original results can be precisely reproduced. [3]
The replication crisis (or credibility crisis) is a methodological crisis in science that researchers began to acknowledge around the 2010s. The controversy revolves around the lack of reproducibility of many scientific findings, including those in psychology (e.g., among 100 studies, less than 50% of the findings were replicated).
A succession crisis is a crisis that arises when an order of succession fails, for example when a monarch dies without an indisputable heir. It may result in a war of succession. Examples include (see List of wars of succession): The Wars of The Roses; Multiple periods during the history of the Roman Empire: Year of the Four Emperors (69 AD)
President Donald Trump revealed early Friday that both he and the first lady have tested positive for the COVID-19. While the full extent of the president's condition is not known, a White House ...

Entry into S-phase during endoreduplication (and mitosis) is regulated through the formation of a prereplicative complex (pre-RC) at replication origins, followed by recruitment and activation of the DNA replication machinery. In the context of endoreduplication these events are facilitated by an oscillation in cyclin E-Cdk2 activity.
