Relative rate constants for the gas-phase reactions of OH radicals with a series of bi- and tricyclic alkanes have been determined at 299 ± 2 K, using methyl nitrite photolysis in air as a source of OH radicals.

Computational Study of Hydrogen Shifts and Ring-Opening Mechanisms in α-Pinene Ozonolysis Products.
Journal of Physical Chemistry A, 2015Autoxidation by sequential peroxy radical hydrogen shifts (H-shifts) and O2 additions has recently emerged as a promising mechanism for the rapid formation of highly oxidized, low-volatility organic compounds in the atmosphere.

Rings of eventually constant sequences.
Journal of Mathematical Sciences, 2003All rings are assumed to be associative and to have non-zero identity elements. Throughout \(A\) is a ring with Jacobson radical \(J(A)\), \(B\) is a unitary subring in \(A\), \(\{A_i\}_{i=1}^\infty\) is a countable set of copies of \(A\), \(D\) is the direct product of all the rings \(A_i\), \(B'\) is the subring \(\{(b,b,\dots)\mid b\in B\}\) of \(D\)

The sharp constant in the ring lemma
Complex Variables, Theory and Application: An International Journal, 1997In his paper [2] Lowell J. Hansen found a (nonlinear) recurrence formula for the (sharp constant appearing in the “Ring Lemma” of Rodin and Sullivan [3]. In the following we improve Hansen's result and replace his recurrence relation by a linear recurrence formula leading to a closed formula for the Ring Lemma constant.

Practical Constant-Size Ring Signature
Journal of Computer Science and Technology, 2018Bitcoin has gained its popularity for almost 10 years as a “secure and anonymous digital currency”. However, according to several recent researches, we know that it can only provide pseudonymity rather than real anonymity, and privacy has been one of the main concerns in the system similar to Bitcoin. Ring signature is a good method for those users who

Constant Volume Ring Shear Apparatus
Geotechnical Testing Journal, 1996Abstract The paper describes a constant volume ring shear apparatus that allows the measurement of the undrained peak and residual shear strengths of cohesive soils. The undrained peak and residual strengths are applicable to seismic stability evaluations of slopes comprised of or founded on cohesive soil.

The instability of the thin vortex ring of constant vorticity
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1977A theoretical investigation of the instability of a vortex ring to short azimuthal bending waves is presented. The theory considers only the stability of a thin vortex ring with a core of constant vorticity (constant /r) in an ideal fluid. Both the mean flow and the disturbance flow are found as an asymptotic solution in e =a/R, the ratio of core ...

Dielectric elastomers are referred to as artificial muscles because of their excellent properties. However, the need for high operating voltage limits their practical application. A reduction of the operating voltage can be achieved with novel elastomers
