The demonstrated occurrence of the mismatches (variations) in otherwise complementary syntheses ("self-reproduction"), in this RNA system, opens an experimental and conceptual perspective to explore the origin of life (and its definition), on the apparent edge of the origin.
Abrupt change at 0.1 sec in estimated derivative obtained by all methods except method 1, demonstrates occurrence of fault in power system.
Also semithin sections of specimens demonstrate occurrence of numerous tubules between fibers of the polyester fleece.
The study has demonstrated occurrence of influenza A viruses in animals in Uganda.
This study has demonstrated occurrence of influenza viruses in animals in Uganda.
Previous results demonstrated occurrence of mitochondrial dysfunction in fibers from skeletal muscle of Col6a1−/− mice [7], as well as in myoblasts from patients affected by UCMD [27,34].
There is as yet no direct evidence for aneuploidy in Euglena; however, the demonstrated occurrence of aneuploidy in trypanosomatids, in conjunction with the results presented here, makes aneuploidy a distinct possibility in Euglena.
EM investigations demonstrated occurrence of typical NE secretion granules in all the NE tumour cells, but not in any of the non-NE tumour cells, thus confirming the predefined NE/non-NE characteristics of the cell lines used.
While local adaptation is likely to be of commonplace occurrence, demonstrating its occurrence can be difficult and take substantial research efforts [ 1- 3].
After demonstrating the occurrence of skyrmion phases in ultra-thin transition metal films, we analyse how the magnetic interactions in such a system depend on the interface structure and composition.
Efflorescences and moisture stains were observed on the walls inside the church (Additional file 1: Figure S1c) demonstrating the occurrence of water-soluble salt accumulation.
