Rapid DNA Maturity Assessment

Author(s)
Erica L. Romsos, Sanae Lembirick, Peter Vallone
Two fully integrated rapid DNA platforms were tested as a part of a rapid DNA maturity assessment in the fall of 2014. The assessment was conducted with sets of

Direct Immersion Annealing of Thin Block Copolymer Films

Author(s)
Jack F. Douglas, Alamgir Karim, Arvind Arvind Modi1, Sarang Bhaway, Bryan D. Vogt, Abdullah Al-Enizi, Ahmed Elzatahry, Ashutosh Sharma
We demonstrate that direct immersion annealing (DIA) greatly enhances the rate at which block copolymer (BCP) films order into stable morphologies when the BCP

Optomechanical Raman-Ratio Thermometry

Author(s)
Katarina Cicak, Thomas P. Purdy, Pen Li Yu, Nir Kampel, Bob Peterson, Raymond Simmonds, Cindy Regal
The temperature dependence of the asymmetry between Stokes and anti-Stokes Raman scattering can be exploited for self-calibrating, optically-based thermometry

Prospects for atomic clocks based on large ion crystals.

Author(s)
John J. Bollinger, Kyle Arnold, Elnur Haciyev, Chern Hui Lee, Eduardo Paez, M. D. Barrett
We investigate the feasibility of precision frequency metrology with large ion crystals. For clock candidates with a negative differential static polarisability

Optomechanical reference accelerometer

Author(s)
Oliver Gerberding, Felipe Guzman, John T. Melcher, Jon R. Pratt, Jacob Taylor
We present an opto-mechanical accelerometer device with high dynamic range, high bandwidth and readout noise levels exceeding 10 μg/√Hz . The straightforward

Broadband phase spectroscopy over turbulent air paths

Author(s)
Fabrizio R. Giorgetta, Greg B. Rieker, Esther Baumann, William C. Swann, Laura C. Sinclair, Jonathan Kofler, Ian R. Coddington, Nathan R. Newbury
Broadband atmospheric phase spectra are measured at sub-milliradian uncertainty corresponding to a 10-13 refractive index change, despite strong decoherence

International Round-Robin Study on Thermoelectric Transport Properties of n-type Half-Heusler from 300 K to 773 K

International transport property measurement round-robins have been conducted by the Thermoelectric Annex under the International Energy Agency (IEA)

Viscosity Measurements of Aviation Turbine Fuels

Author(s)
Tara J. Fortin, Arno D. Laesecke
Kinematic viscosity has been measured for nine separate aviation turbine fuel samples. The nine samples span the range of fuel types available: conventional

Retention projection enables accurate calculation of liquid chromatographic retention times across labs and methods

Yamil Simon, Daniel Abate-Pella, Dana M. Freund, Yan Ma, Adrian Hegeman, Yan Ma, Tobias Kind, O Fiehn, Birgit Beck, Emma L. Schymanski, Corey D. Broeckling, David V. Huhman, Lloyd W. Summer, Oleg V. Krokhin, Dwight R. Stoll
Identification of small molecules by liquid chromatography-mass spectrometry (LC-MS) could be greatly improved if the chromatographic retention information

Perceptual expertise in forensic facial image comparison

Author(s)
P. Jonathon Phillips, David White, Alice O'Toole, Carina A. Hahn, Matthew Hill
Forensic facial identification examiners are required to match the identity of faces in images that vary substantially, owing to changes in viewing conditions

On-Chip Integrated Silicon Photonic Thermometers

Author(s)
Nikolai N. Klimov, Thomas P. Purdy, Zeeshan Ahmed
The fundamental limitations of resistance-based thermometry and the desire to reduce sensor ownership have produced considerable interest in the development of

Optimizing Data Logger Setup for Vaccine Temperature Monitoring

Author(s)
Michal J. Chojnacky, Luis Chaves Santacruz, W Wyatt Miller, Gregory F. Strouse
Accidental freezing of refrigerated vaccine represents a significant public and private healthcare cost. Freeze-damaged vaccines lose their effectiveness

Muffin tin potentials in EXAFS analysis

Author(s)
Bruce D. Ravel
Muffin tin potentials are the standard tool for calculating the potential surface of a cluster of atoms for use in the analysis of extended x-ray-absorption

Conductance Hysteresis in the Voltage-Dependent Anion Channel

Author(s)
Shay M. Rappaport, Oscar Teijido, David Hoogerheide, Tatiana K. Rostovtseva, Alexander M. Berezhkovskii, Sergey M. Bezrukov
In contrast to the voltage gating of ion-selective channels of electrophysiology, the mechanisms of voltage sensitivity of ¿large¿ beta-barrel channels remain

Correction for stray light in optical spectroscopy of crystals

Author(s)
Richard W. Hendler, Curtis Meuse, David Travis Gallagher, Joerg Labahn, Jan Kubicek, Paul D. Smith, John W. Kakareka
It has long been known in spectroscopy that light not passing through a sample, but reaching the detector (i.e. stray light) results in a distortion of the
