In the past decade, microfabricated devices have been developed that can separate, detect, and analyze various biomolecules [1]. In contrast to the sieving gels that are historically used in these studies, microfabricated devices are precisely designed and constructed. The deterministic structure of these devices facilitates experiment design and testing of theory. Periodic nanofilter arrays ha...

Progression to end-stage renal disease is common in chronic nephropathies, independent of the initial insult. While genetic factors may contribute to susceptibility and progression of renal disease, proteinuria has been documented as an independent predictor of outcome. Reduction of urinary protein levels by restoration of glomerular sieving function with renin-angiotensin system (RAS) blockers...

Aminoacyl-tRNA synthetases (aaRSs) constitute a family of ubiquitously expressed essential enzymes that ligate amino acids to their cognate tRNAs for protein synthesis. Recently, aaRS mutations have been linked to various human diseases; however, how these mutations lead to diseases has remained unclear. In order to address the importance of aminoacylation fidelity in multicellular organisms, w...

We examine a few families of semistandard Young tableaux, for which we observe the cyclic sieving phenomenon under promotion. The first family consider consists stretched hook shapes, where use cocharge generating polynomial as CSP-polynomial. second skew consisting rectangles. Again, charge together with promotion exhibits phenomenon. This generalizes earlier result by B. Rhoades and later F...

In the past ten years much work has been undertaken on developing mixture theory continuum models to describe kinetic sieving-driven size segregation. We propose an extension to these models that allows their application to bidisperse flows over inclined channels, with particles varying in density and size. Our model incorporates both a recently proposed explicit formula for how the total press...

Many organic compounds cause an irreversible damage to human health and the ecosystem and are present in water resources. Among these hazard substances, phenolic compounds play an important role on the actual contamination. Utilization of membrane technology is increasing exponentially in drinking water production and waste water treatment. The removal of organic compounds by nanofiltration mem...

Graphene membranes have the potential to exceed the permeance and selectivity limits of conventional gas separation membranes. Realizing this potential in practical systems relies on overcoming numerous scalability challenges, such as isolating or sealing permeable defects in macroscopic areas of graphene that can compromise performance and developing methods to create high densities of selecti...
