Bonding titanium to Rene 41 alloy [PDF]

open access: yes, 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 ...

Two-level system with a thermally fluctuating transfer matrix element: Application to the problem of DNA charge transfer

open access: yes, 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 ...

Coherent pair production in deformed crystals with a complex base

open access: yes, 2005
We investigate the coherent electron-positron pair creation by high-energy photons in a periodically deformed single crystal with a complex base. The formula for the corresponding differential cross-section is derived for an arbitrary deformation field ...

Clamp-mount device [PDF]

open access: yes, 1983
A clamp-mount device is disclosed for mounting equipment to an associated I-beam and the like structural member of the type having oppositely extending flanges wherein the device comprises a base and a pair of oppositely facing clamping members carried ...

Mechanisms of DNA Hybridization: Transition Path Analysis of a Simulation-Informed Markov Model

open access: yes, 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]

open access: yes, 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.

Molecular Dynamics Simulation of Homo-DNA: The Role of Crystal Packing in Duplex Conformation

open access: yesCrystals, 2019
The (4′→6′)-linked DNA homolog 2′,3′-dideoxy-β-D-glucopyranosyl nucleic acid (dideoxy-glucose nucleic acid or homo-DNA) exhibits stable self-pairing of the Watson−Crick and reverse-Hoogsteen types, but does not ...
