Beneficial mutation-selection balance and the effect of linkage on positive selection
Michael M. Desai, Daniel S. Fisher
When beneficial mutations are rare, they accumulate by a series of selective sweeps. But when they are common, many beneficial mutations will occur before any can fix, so there wil…
Signed differential posets and sign-imbalance
Thomas Lam
We study signed differential posets, a signed version of differential posets. These posets satisfy enumerative identities which are signed analogues of those satisfied by different…
Surfactant Driven Fracture of Interfacial Particle Rafts
Dominic Vella, Ho-Young Kim, Pascale Aussillous +1
We investigate the dynamic fracture of a close-packed monolayer of particles, or particle raft, floating at a liquid-gas interface induced by the localised addition of surfactant.…
Small-angle impurity scattering and the spin Hall conductivity in 2D systems
A. V. Shytov, E. G. Mishchenko, H. -A. Engel +1
An arbitrarily small concentration of impurities can affect the spin Hall conductivity in a two-dimensional semiconductor system. We develop a Boltzmann-like equation that can be u…
A heuristic quantum theory of the integer quantum Hall effect
Tobias Kramer
Contrary to common belief, the current emitted by a contact embedded in a two-dimensional electron gas (2DEG) is quantized in the presence of electric and magnetic fields. This obs…
Getting Its Kicks: A VLBA Parallax for the Hyperfast Pulsar B1508+55
S. Chatterjee, W. H. T. Vlemmings, W. F. Brisken +7
The highest velocity neutron stars establish stringent constraints on natal kicks, asymmetries in supernova core collapse, and the evolution of close binary systems. Here we presen…
