DOI: 10.1103/physreva.104.023316
Abstract: We study the dynamics of one-dimensional bosons trapped in a box potential, in the presence of a barrier creating a tunable weak-link, thus realizing a one dimensional Bose-Josephson junction. By varying the initial population imbalance… read more here.

DOI: 10.1103/physrevb.104.174517
Abstract: We develop a theory for the dynamics of an Andreev bound state (ABS) hosted by a weak link of finite length for which charging effects are important. We derive the linear response of both the… read more here.

Synonymous mutations make dramatic contributions to fitness when growth is limited by a weak-link enzyme

DOI: 10.1371/journal.pgen.1007615
Abstract: Synonymous mutations do not alter the specified amino acid but may alter the structure or function of an mRNA in ways that impact fitness. There are few examples in the literature, however, in which the… read more here.

DOI: 10.3390/buildings13051230
Abstract: This article examines the application of the theory of critical strain energy levels to the determination of the limiting states of rod systems. A redundant truss is chosen to illustrate the peculiarities of changes in… read more here.

Mutations that improve efficiency of a weak-link enzyme are rare compared to adaptive mutations elsewhere in the genome

DOI: 10.7554/elife.53535
Abstract: New enzymes often evolve by gene amplification and divergence. Previous experimental studies have followed the evolutionary trajectory of an amplified gene, but have not considered mutations elsewhere in the genome when fitness is limited by… read more here.
