Polyelectrolyte association and solvation

July 10, 2018
Author(s)
Alexandros Chremos, Jack F. Douglas
There has been significant interest in the tendency of highly charged particles having the same charge to form dynamic clusters in solution, but an accepted theoretical framework that can account for this ubiquitous phenomenon has been slow to develop. The

Programmable assembly of three-dimensional binary superlattices from multi-flavored DNA- functionalized particles

Evan Pretti, Hasan Zerze, Minseok Song, Yajun Ding, Nathan Mahynski, Harold Hatch, Vincent K. Shen, Jeetain Mittal
Programmable self-assembly of nano- or micron-sized colloidal particles can be achieved by grafting single- stranded DNA sequences onto the surfaces of colloids. However, this assembly is traditionally premised on the pairwise interaction between a single

Shape Analysis, Lebesgue Integration and Absolute Continuity Connections

July 10, 2018
Author(s)
Javier Bernal
As shape analysis of the form presented in Srivastava and Klassen’s textbook “Functional and Shape Data Analysis” is intricately related to Lebesgue integration and absolute continuity, it is advantageous to have a good grasp of the latter two notions

Johnathon D. Gard, Daniel T. Becker, Douglas A. Bennett, Joseph W. Fowler, Gene C. Hilton, John A. Mates, Carl D. Reintsema, Daniel R. Schmidt, Daniel S. Swetz, Joel N. Ullom
The readout requirements for instruments based on transition-edge sensors (TESs) have dramatically increased over the last decade as demand for systems with larger arrays and faster sensors has grown. Emerging systems are expected to contain many thousands

Characteristics of Firebrands Collected from Actual Urban Fires

July 9, 2018
Author(s)
Samuel L. Manzello, Sayaka Suzuki
The characteristics of firebrands collected from a recent urban fire in Japan are described. Specifically, this fire broke out from a Chinese restaurant in Itoigawa-city, Niigata, Japan on December 22nd 2016. On the day of the fire, strong winds resulted

Deep Learning-Based Intrusion Detection With Adversaries

July 9, 2018
Author(s)
