"We may be able to do without expensive hedge-fund managers and all the hassle, including the due diligence, the lack of liquidity, the lack of transparency, the lack of capacity and the fear of style drift" — changes in a fund's strategy — "which comes with investing in hedge funds," Kat and Palaro wrote in a working paper about the project which they published last year.
The motivation for the groupwise phase estimation and correction method comes from the fact that the instantaneous phase drift changes gradually while not arbitrarily from time to time due to the nature of ocean waters.
To evaluate the reproducibility of the Čḯxwicən fishbone data, and the possibility of "protocol drift" – changes in how specimens and bone modifications were identified over the course of analysis – we reanalyzed samples of fish remains that were previously documented during three discrete stages (beginning, middle, and end) of the Čḯxwicən project.
However, this ideal scenario is frequently complicated by membrane potential drift, changes in the electrode seal, movement artifacts (e.g. respiratory movements, heartbeat) or other factors, particularly when large time spans are to be considered.
To quantify transcriptional drift changes with age (type II), we calculated the variance of the log-fold change for genes involved in each pathway.
Convergently modified binding sites are over-enriched for SP1 functional categories, which cannot be explained by neutral processes, such as genetic drift, changes in dinucleotide composition, or lineage-specific changes in mutational bias.
In addition to genetic drift, changes in climatic conditions likely have contributed to the observed demographic changes since the HEC appears to be sensitive to temperature as has been shown for many other lepidopterans [ 59- 61].
Finally, strains also evolve through small "antigenic drift" changes in one of the outer capsid genes, thus eluding typing by the reverse-transcription polymerase chain reaction (RT-PCR) primers [ 18, 26, 27].
By identifying the abstracts lost or gained between sequential runs, we identified a number of causal factors for literature drift: Changes to the various components of the NCBI search engine that result in different results for the same query.
Since inbreeding affects all loci equally and genetic drift changes frequency of loci randomly, inbreeding may not induce linkage disequilibrium between neighboring loci, whereas selection will drive linked alleles to high frequency [ 6].
