An accurate and rapid single step protocol for enumeration of cytokine positive T lymphocytes

September 2, 2020
Author(s)
Deepa Rajagopal, Linhua Tian, Shiqiu Xiong, Hao-Wei Wang, Jonathan Campbell, Luisa Saraiva, S Vessillier
Activation of T lymphocytes leads to differentiation, characterized by the ability to induce production of cytokines. Accurate determination of cellular subsets that secrete particular cytokine(s) is therefore, a significant parameter for functional

Design and Engineering Colloidal Magnetic Particles for Nanoscale Thermometry

September 2, 2020
Author(s)
Adam J. Biacchi, Thinh Q. Bui, Cindi L. Dennis, Solomon I. Woods, Angela R. Hight Walker
Thermometry based on magnetic nanoparticles (MNPs) is an emerging technology that allows for remote temperature measurements throughout a volume that are impossible to achieve using conventional probe-based or optical methods. This metrology is based on

Measurement of the 2P1/2-2P3/2 fine structure splitting in fluorine-like Kr, W, Re, Os and Ir

September 2, 2020
Author(s)
Galen O'Neil, Samuel C. Sanders, Paul Szypryt, Dipti Goyal, Amy Gall, Yang Yang, Samuel M. Brewer, William Doriese, Joseph Fowler, Daniel Swetz, Joseph Tan, Joel Ullom, Andrey V. Volotka, Endre Takacs, Yuri Ralchenko
Quantum electrodynamics (QED) is currently considered to be one of the most accurate theories of fundamental interactions. As its extraordinary precision offers unique scientific opportunities, e.g., search for new physics, stringent experimental tests of

Modeling Temperature Effects on a Coriolis Mass Flowmeter

September 2, 2020
Author(s)
Fabio O. Costa, Jodie Gail Pope, Keith A. Gillis
Coriolis mass flowmeters are known to be stable, have low uncertainty (± 0.1 %), and are insensitive to fluid properties. This meter type is used for many applications, including as transfer standards for proficiency testing and liquified natural gas (LNG)

Users Guide to the HVACSIM+ Configuration Tool

September 2, 2020
Author(s)
Michael A. Galler
HVACSIM+ (HVAC SIMulation PLUS other systems) was introduced by the National Institute of Standards and Technology (NIST) in 1985 as a computer simulation tool to simulate building systems. The HVACSIM+ computer program package and manuals have been

A NEIGHBORHOOD-BASED NEURAL NETWORK FOR MELT POOL PREDICTION AND CONTROL

September 1, 2020
Author(s)
Paul Witherell, Vadim Shapiro, Yaqi Zhang
One of the most prevalent additive manufacturing processes, the powder bed fusion process, is driven by a moving heat source that melts metals to build a part. This moving heat source, and the subsequent formation and moving of a melt pool, plays an

Distance Computation Based on Coupled Spin-Torque Oscillators: Application to Image Processing

September 1, 2020
Author(s)
Minsuk Koo, Matthew Pufall, Yong Shim, Anthony B. Kos, Gyorgy Csaba, Wolfgang Porod , William Rippard, Kaushik Roy
Recent research on nano-oscillators has shown the possibility of using a coupled-oscillator network as a core-computing primitive for non-Boolean computation. The spin-torque oscillator (STO) is an attractive candidate because it is CMOS compatible, highly

High-Resolution Biochemical Activity Measurements with Commercial Transistors

September 1, 2020
Author(s)
Seulki Cho, Son T. Le, Curt A. Richter, Arvind Balijepalli
We demonstrate that single-gated, commercially-sourced, field-effect transistors (FETs) operated with a lock- in amplifier (LIA) under closed-loop control can achieve an average pH resolution of 9x10^-4. This performance represents an 8-fold improvement

Method development in interaction polymer chromatography

September 1, 2020
Author(s)
Andre M. Striegel
Interaction polymer chromatography (IPC) is an umbrella term covering a large variety of primarily enthalpically-dominated macromolecular separation methods. These include temperature- gradient interaction chromatography, interactive gradient polymer
