Kinetic Anomalies in Addition-Aggregation Processes [PDF]

open access: yes, 2003
We investigate irreversible aggregation in which monomer-monomer, monomer-cluster, and cluster-cluster reactions occur with constant but distinct rates K_{MM}, K_{MC}, and K_{CC}, respectively.

Complete addition laws on abelian varieties [PDF]

open access: yes, 2012
We prove that under any projective embedding of an abelian variety A of dimension g, a complete system of addition laws has cardinality at least g+1, generalizing of a result of Bosma and Lenstra for the Weierstrass model of an elliptic curve in P^2.

Aerobic addition of secondary phosphine oxides to vinyl sulfides: a shortcut to 1-hydroxy-2-(organosulfanyl)ethyl(diorganyl)phosphine oxides

open access: yesBeilstein Journal of Organic Chemistry, 2015
Secondary phosphine oxides react with vinyl sulfides (both alkyl- and aryl-substituted sulfides) under aerobic and solvent-free conditions (80 °C, air, 7–30 h) to afford 1-hydroxy-2-(organosulfanyl)ethyl(diorganyl)phosphine oxides in 70–93% yields.

Boolean Masking for Arithmetic Additions at Arbitrary Order in Hardware

open access: yesApplied Sciences, 2022
Modular addition is an important component of many cryptographic algorithms such as ARX-ciphers and lattice-based post-quantum secure schemes. In order to protect devices that execute these algorithms against side-channel attacks, countermeasures such as

Addition-Deletion Networks

open access: yes, 2007
We study structural properties of growing networks where both addition and deletion of nodes are possible. Our model network evolves via two independent processes.

Defining 'Speech': Subtraction, Addition, and Division [PDF]

open access: yes, 2016
In free speech theory ‘speech’ has to be defined as a special term of art. I argue that much free speech discourse comes with a tacit commitment to a ‘Subtractive Approach’ to defining speech.
