Twisted gamma filtration and algebras with orthogonal involution
Caroline Junkins
For the Grothendieck group of a split simple linear algebraic group, the twisted gamma-filtration provides a useful tool for constructing torsion elements in gamma-rings of twisted…
Dynamics of unconfined spherical flames
Louis Leblanc, Maha Manoubi, Kadeem Dennis +3
Using the soap bubble technique, we visualize the dynamics of unconfined hydrogen-air flames using high speed schlieren video. We show that for sufficiently weak mixtures, i.e., lo…
Translocation of a Polymer through a Nanopore across a Viscosity Gradient
Hendrick W. de Haan, Gary W. Slater
The translocation of a polymer through a pore in a membrane separating fluids of different viscosities is studied via several computational approaches. Starting with the polymer ha…
Von Neumann Categories
Richard Blute, Marc Comeau
In this paper, we introduce the notion of a von Neumann category, as a generalization and categorification of von Neumann algebra. A von Neumann category is a premonoidal category…
Aptamer-based Impedimetric Sensor for Bacterial Typing
Mahmoud Labib, Anna S. Zamay, Olga S. Kolovskaya +6
The development of an aptamer-based impedimetric sensor for typing of bacteria (AIST-B) is presented. Highly specific DNA aptamers to Salmonella enteritidis were selected via Cell-…
On the Parity Problem in One-Dimensional Cellular Automata
Heater Betel, Pedro P. B. de Oliveira, Paola Flocchini
We consider the parity problem in one-dimensional, binary, circular cellular automata: if the initial configuration contains an odd number of 1s, the lattice should converge to all…
