As the protein tags experience larger frictional drags, it is expected that different parts of the chain will not move through the double nanopore system with uniform velocity which will then introduce error in genomic length determination. The dispersion in velocity will also depend on the ...
The magnetic flux rope is among the most fundamental magnetic configurations in plasma. Although its presence after solar eruptions has been verified by spacecraft measurements near Earth, its formation on the Sun remains elusive, yet is critical to understanding a broad spectrum of phenomena. Here ...
The average age of the participants was 44 years (range 25–64). Most had been involved with the CRHP for a long time, with the average length of involvement for the VHWs being 18 years (range 5–31) and for the women from the Mahila Mandal groups 13 years (range 2–29). The vi...
