We study polymer translocation through a nanopore subject to conformational differences created by putting two different solvents at the cis and trans compartments using Langevin dynamics in three dimensions (3D). Initially a fraction of the chain is placed in a good solvent at the cis side and the rest of the chain at the trans side is immersed in a bad solvent where it forms a globule. We stu...

He,Yang. M.S.E., Purdue University, December, 2013. Photochemical reactions of Naproxen, Ibuprofen and Tylosin. Major Professor: Inez Hua. Pharmaceuticals and personal care products (PPCPs) include a wide range of compounds that are used extensively and sometimes daily by people. Some PPCPs have been detected in surface water (streams, rivers, lakes) due to incomplete removal in wastewater trea...

Ubiquitylation is a posttranslational protein modification that modulates various cellular processes of key significance, including protein degradation and DNA damage repair. In animals subjected to transient cerebral ischemia, ubiquitin-conjugated proteins accumulate in Triton-insoluble aggregates. Although this process is widely considered to modulate the fate of postischemic neurons, few att...

An asymptotic study is made of nonlinear effects in steady radiating waves due to moving sources dispersive media. The focus on problems where the radiated have exponentially small amplitude with respect a parameter μ≪1, as for instance free-surface submerged body limit low Froude number. In such settings, weakly (controlled by source strength ɛ) can be important linear propagation μ), and comp...

ɛ-Poly-l-lysine (ɛ-PL) is a cationic peptide with a broad-spectrum antimicrobial activity. This study investigates the use of ɛ-PL as natural antimicrobial to inhibit fungal growth and to reduce aflatoxins (AFs) production. Antifungal activity of starch biofilms with different concentrations of ɛ-Poly-l-lysine (ɛ-PL) was determined in solid medium against Aspergillus parasiticus (AFs producer) ...

A graph where each vertex v has a list L(v) of available colors is L-colorable if there proper coloring such that the color in for v. k-choosable every assignment L at least k to guarantees an L-coloring. Given L, L-request c∈L(v). In this paper, we look variant widely studied class precoloring extension problems from Dvořák, Norin, and Postle (J. Graph Theory, 2019), wherein one must satisfy “...
