Yamada K, Bixler B, Sakurai Y, Ashton P, Sugiyama J, Arnold K, et al.
Rev Sci Instrum . 2024 Feb; 95(2). PMID: 38385955
We present the requirements, design, and evaluation of the cryogenic continuously rotating half-wave plate (CHWP) for the Simons Observatory (SO). SO is a cosmic microwave background polarization experiment at Parque...

Shroyer J, Nelson M, Walters L, Johnson B
Rev Sci Instrum . 2022 Dec; 93(11):113107. PMID: 36461559
We present the design and measured performance of a light emitting diode (LED) module for spatially mapping kinetic inductance detector (KID) arrays in the laboratory. Our novel approach uses a...

Horm Behav . 2020 Apr; 122:104757. PMID: 32305342
The traditional focus of physiological and functional genomic research is on molecular processes that play out within a single multicellular organism. In the colonial (eusocial) insects such as ants, bees,...

Johnson B, Columbro F, Araujo D, Limon M, Smiley B, Jones G, et al.
Rev Sci Instrum . 2017 Nov; 88(10):105102. PMID: 29092514
In this paper, we present the design and measured performance of a novel cryogenic motor based on a superconducting magnetic bearing (SMB). The motor is tailored for use in millimeter-wave...

Crowther T, Todd-Brown K, Rowe C, Wieder W, Carey J, Machmuller M, et al.
Nature . 2016 Dec; 540(7631):104-108. PMID: 27905442
The majority of the Earth's terrestrial carbon is stored in the soil. If anthropogenic warming stimulates the loss of this carbon to the atmosphere, it could drive further planetary warming....

McCarrick H, Flanigan D, Jones G, Johnson B, Ade P, Araujo D, et al.
Rev Sci Instrum . 2015 Jan; 85(12):123117. PMID: 25554282
We discuss the design, fabrication, and testing of prototype horn-coupled, lumped-element kinetic inductance detectors (LEKIDs) designed for cosmic microwave background studies. The LEKIDs are made from a thin aluminum film...

Chow J, Gambetta J, Magesan E, Abraham D, Cross A, Johnson B, et al.
Nat Commun . 2014 Jun; 5:4015. PMID: 24958160
With favourable error thresholds and requiring only nearest-neighbour interactions on a lattice, the surface code is an error-correcting code that has garnered considerable attention. At the heart of this code...

Troiano J, Johnson B, Powell S, Schoenig S
Environ Monit Assess . 2013 Nov; 32(3):269-88. PMID: 24214139
An empirical approach to profiling areas of ground water contamination by pesticides was devised that did not rely upon determining the level of vulnerability between land areas and that did...

Vox Sang . 2013 Mar; 105(2):108-15. PMID: 23517282
Background And Objectives: LDL apheresis is used to treat patients with familial hypercholesterolaemia, and low-volume plasmapheresis for plasma donation may similarly lower cholesterol levels in some donors. This study was...
