Bonding titanium to Rene 41 alloy [PDF]
, 1972 Pair of intermediate materials joined by electron beam welding method welds titanium to Rene 41 alloy. Bond is necessary for combining into one structure high strength-to-density ratio titanium fan blades and temperature resistant nickel-base alloy ...

, 2002 Charge transfer along the base-pair stack in DNA is modeled in terms of thermally-assisted tunneling between adjacent base pairs. Central to our approach is the notion that tunneling between fluctuating pairs is rate-limited by the requirement of their ...

Hexameric helicase G40P unwinds DNA in single base pair steps
eLife, 2019 Most replicative helicases are hexameric, ring-shaped motor proteins that translocate on and unwind DNA. Despite extensive biochemical and structural investigations, how their translocation activity is utilized chemo-mechanically in DNA unwinding is ...

Conserved arginines on the rim of Hfq catalyze base pair formation and exchange
Nucleic Acids Research, 2013 The Sm-like protein Hfq is required for gene regulation by small RNAs (sRNAs) in bacteria and facilitates base pairing between sRNAs and their mRNA targets.

Use of Nucleic Acid Analogs for the Study of Nucleic Acid Interactions
Journal of Nucleic Acids, 2011 Unnatural nucleosides have been explored to expand the properties and the applications of oligonucleotides. This paper briefly summarizes nucleic acid analogs in which the base is modified or replaced by an unnatural stacking group for the study of ...

DNA with Artificial Base Pairs
CHIMIA, 2005 The introduction of a single base pair with the electronically complementary base surrogates phenyl- (P) and pentafluorophenyl-deoxyriboside (F5) into DNA oligonucleotides leads to a strong decrease in duplex stability. Longer stretches with alternating P-F5 pairs can lead to duplexes with increased stability as compared to their counterparts

Mechanisms of DNA Hybridization: Transition Path Analysis of a Simulation-Informed Markov Model
, 2018 Complementary DNA strands in solution reliably hybridize to form stable duplexes. We study the kinetics of the hybridization process and the mechanisms by which two initially isolated strands come together to form a stable double helix.

Parametrizing quartic algebras over an arbitrary base [PDF]
, 2010 We parametrize quartic commutative algebras over any base ring or scheme (equivalently finite, flat degree four $S$-schemes), with their cubic resolvents, by pairs of ternary quadratic forms over the base.
