Angelos Stavrou, Jeff Voas, Tom T. Karygiannis, Stephen Quirolgico
Recent advancements in hardware have increased the computing power, memory, storage, and wireless connectivity of handheld mobile devices. Smart-phone devices...

Numerical Study of the Thermodynamics of Clinoatacamite

Author(s)
Ehsan Khatami, Joel Helton, Marcos Rigol
In this Brief Report, we discuss the use of linked-cluster expansions in solving quantum models that break certain symmetries of the underlying lattice. We...

Measurements and Modeling Study on a High-Aromatic Diesel Fuel

Author(s)
Bret Windom, Marcia L. Huber, Thomas J. Bruno, A L. Lown, C T. Lira
The increasing cost of diesel fuel, potential for supply disruptions, and environmental concerns have resulted in a great deal of research to improve the...

Families of Elliptic Curves with Rational 3-torsion

Author(s)
Dustin Moody, Hongfeng Wu
In this paper we look at three families of elliptic curves with rational 3-torsion over a finite field. These families include Hessian curves, twisted Hessian...

Optimization of the TES-bias circuit for a multiplexed microcalorimeter array

In the detector-bias circuit of a transition-edge-sensor (TES) microcalorimeter, the TES-shunt resistor (Rsh) and the thermal conductance to the cryogenic bath...

Probing the timescale of the exchange interaction in a ferromagnetic alloy

Author(s)
Justin M. Shaw, Stefan Mathias, Chan La-O-Vorakiat, Hans T. Nembach, Thomas J. Silva, Mark Siemens, Henry Kapteyn, Margaret Murnane
The underlying physics of all ferromagnetic behavior is the cooperative interaction between individual atomic magnetic moments that results in a macroscopic...

DNA Molecules Descending a Nanofluidic Staircase by Entropophoresis

Author(s)
Samuel M. Stavis, Jon C. Geist, Michael Gaitan, Laurie E. Locascio, Elizabeth A. Strychalski
A complex entropy gradient for confined DNA molecules was engineered for the first time. Following the second law of thermodynamics, this enabled the directed...

Spin transport in memristive devices
