A Community Initiative to Increase Colorectal Cancer Knowledge, Awareness, and Intent to Screen in an Underserved Region.

Colorectal cancer (CRC) is a leading cause of cancer-related deaths in the United States despite the availability of effective preventive screening. This project was designed as a community awareness initiative to increase CRC awareness, knowledge, and intent to discuss and complete CRC screening. This quasi-experimental study had a QI focus and used a convenience sample in a public setting assessing CRC awareness, knowledge, and intent to discuss and complete screening after participating in an inflatable colon tour.

Frequency-dependent conductivity of concentrated electrolytes: A stochastic density functional theory.

The response of ionic solutions to time-varying electric fields, quantified by a frequency-dependent conductivity, is essential in many electrochemical applications. Yet, it constitutes a challenging problem due to the combined effect of Coulombic interactions, hydrodynamics, and thermal fluctuations. Here, we study the frequency-dependent conductivity of ionic solutions using a stochastic density functional theory.

The Process-Directed Self-Assembly of Block Copolymer Particles.

The kinetic paths of structural evolution and formation of block copolymer (BCP) particles are explored using dynamic self-consistent field theory (DSCFT). It is shown that the process-directed self-assembly of BCP immersed in a poor solvent leads to the formation of striped ellipsoids, onion-like particles and double-spiral lamellar particles. The theory predicts a reversible path of shape transition between onion-like particles and striped ellipsoidal ones by regulating the temperature (related to the Flory-Huggins parameter between the two components of BCP, χ ) and the selectivity of solvent toward one of the two BCP components.
