Modeling Biocemented Sands: Hypoplastic Model for MICP‐Based Ground Improvement
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 12, Page 4893-4912, 25 August 2026.ABSTRACT Bio‐cementation offers a sustainable and low‐carbon alternative to conventional ground improvement methods, aligning with the growing demand for green geotechnical solutions. To enable reliable numerical simulation of bio‐cemented soil behavior in engineering applications, advanced constitutive models are required to account for the effects of

Small, Volume 22, Issue 47, 21 August 2026.Channel geometry is used to pattern activity in acoustically energized active liquid crystals, producing controlled, directional transport of topological defects. The mechanism is revealed by experiment and minimal modeling, offering a new design principle for programmable topological transport and active microfluidic architectures. ABSTRACT Patterning

Why Have CEO Pay Levels Become Less Diverse?
The Journal of Finance, Volume 81, Issue 4, Page 1893-1950, August 2026.ABSTRACT This paper documents a new stylized fact: the cross‐sectional variation in CEO pay levels has declined precipitously in recent years. We offer one explanation for this decline, namely, firms are increasingly benchmarking CEO compensation to industry peers closest in size, thereby creating pay clusters.

Molecular Microbiology, Volume 126, Issue 2, Page 190-207, August 2026.Here, we demonstrate that polysaccharide chain length regulation plays a distinct role in enabling formation of a cyclic molecule important for the bacterial cell surface. However, this function is necessary, but not sufficient for the cyclic molecule's biosynthesis.

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1998
We have experimentally applied some concepts of “force-free” motion to micron size particles (latex beads). The coupling of dissipation and local spatial asymmetry of the potential experienced by the beads can put them into motion. The potentials used in these experiments are of dielectrophoretic nature.

The Leverage Ratchet Effect [PDF]
SSRN Electronic Journal, 2013 ABSTRACTFirms’ inability to commit to future funding choices has profound consequences for capital structure dynamics. With debt in place, shareholders pervasively resist leverage reductions no matter how much such reductions may enhance firm value. Shareholders would instead choose to increase leverage even if the new debt is junior and would reduce ...

Homo Oeconomicus, 2016
This paper offers a rational economic reading of the career of the historical Jesus of Nazareth. A simple two-period model shows that Jesus may have been trapped by the incentive to maintain and increase his following, which led him to raise his challenge to ever higher levels and confront an increasingly hostile opposition; in a kind of ratchet ...

Symmetry of deterministic ratchets
Physical Review E, 2019We consider the overdamped motion of a Brownian particle in an unbiased force field described by a periodic function of coordinate and time. A compact analytical representation has been obtained for the average particle velocity as a series in the inverse friction coefficient, from which follows a simple and clear proof of hidden symmetries of ratchets,

While many papers in the last few years have dealt with various equations euphemistically called “ratchets,” the original Feyman two-temperature setup has been left largely unchallenged. We present here a look at the details of how this famous engine actually generates motion from a temperature difference.
