Anisotropic Exchange within Decoupled Tetrahedra in the Quantum Breathing Pyrochlore Ba_{3}Yb_{2}Zn_{5}O_{11}.

Physical review letters

Rau JG, Wu LS, May AF, Poudel L, Winn B, Garlea VO, Huq A, Whitfield P, Taylor AE, Lumsden MD, Gingras MJ, Christianson AD.
PMID: 27391749
Phys Rev Lett. 2016 Jun 24;116(25):257204. doi: 10.1103/PhysRevLett.116.257204. Epub 2016 Jun 24.

The low energy spin excitation spectrum of the breathing pyrochlore Ba_{3}Yb_{2}Zn_{5}O_{11} has been investigated with inelastic neutron scattering. Several nearly resolution limited modes with no observable dispersion are observed at 250 mK while, at elevated temperatures, transitions between excited...

A Robust Statistical Model to Predict the Future Value of the Milk Production of Dairy Cows Using Herd Recording Data.

Frontiers in veterinary science

Græsbøll K, Kirkeby C, Nielsen SS, Halasa T, Toft N, Christiansen LE.
PMID: 28261585
Front Vet Sci. 2017 Feb 17;4:13. doi: 10.3389/fvets.2017.00013. eCollection 2017.

The future value of an individual dairy cow depends greatly on its projected milk yield. In developed countries with developed dairy industry infrastructures, facilities exist to record individual cow production and reproduction outcomes consistently and accurately. Accurate prediction of...

The role of maternal obesity in the risk of neuropsychiatric disorders.

Frontiers in neuroscience

Rivera HM, Christiansen KJ, Sullivan EL.
PMID: 26150767
Front Neurosci. 2015 Jun 18;9:194. doi: 10.3389/fnins.2015.00194. eCollection 2015.

Recent evidence indicates that perinatal exposure to maternal obesity, metabolic disease, including diabetes and hypertension, and unhealthy maternal diet has a long-term impact on offspring behavior and physiology. During the past three decades, the prevalence of both obesity and...

Development of a compact in situ polarized ³He neutron spin filter at Oak Ridge National Laboratory.

The Review of scientific instruments

Jiang CY, Tong X, Brown DR, Chi S, Christianson AD, Kadron BJ, Robertson JL, Winn BL.
PMID: 25085178
Rev Sci Instrum. 2014 Jul;85(7):075112. doi: 10.1063/1.4890391.

We constructed a compact in situ polarized (3)He neutron spin filter based on spin-exchange optical pumping which is capable of continuous pumping of the (3)He gas while the system is in place in the neutron beam on an instrument....

Unconventional superconductivity in Ba(0.6)K(0.4)Fe2As2 from inelastic neutron scattering.

Nature

Christianson AD, Goremychkin EA, Osborn R, Rosenkranz S, Lumsden MD, Malliakas CD, Todorov IS, Claus H, Chung DY, Kanatzidis MG, Bewley RI, Guidi T.
PMID: 19092931
Nature. 2008 Dec 18;456(7224):930-2. doi: 10.1038/nature07625.

A new family of superconductors containing layers of iron arsenide has attracted considerable interest because of their high transition temperatures (T(c)), some of which are >50 K, and because of similarities with the high-T(c) copper oxide superconductors. In both...

A survey of excessively worn incisors and periodontal disease in sheep in Dunedin City, Silverpeaks, Bruce and Clutha Counties.

New Zealand veterinary journal

Orr MB, Christiansen KH, Kissling RC.
PMID: 16031297
N Z Vet J. 1986 Jul;34(7):111-5. doi: 10.1080/00480169.1986.35314.

To determine the prevalence of excessively worn incisors (XSW) and periodontal disease (PD) in sheep in Dunedin City, Silverpeaks, Bruce and Clutha Counties, the incisors of 4049 mixed age ewes on 83 farms selected at random were examined between...

Phonon density of states of LaFeAsO(1-x)Fx.

Physical review letters

Christianson AD, Lumsden MD, Delaire O, Stone MB, Abernathy DL, McGuire MA, Sefat AS, Jin R, Sales BC, Mandrus D, Mun ED, Canfield PC, Lin JY, Lucas M, Kresch M, Keith JB, Fultz B, Goremychkin EA, McQueeney RJ.
PMID: 18999629
Phys Rev Lett. 2008 Oct 10;101(15):157004. doi: 10.1103/PhysRevLett.101.157004. Epub 2008 Oct 08.

We have studied the phonon density of states (PDOS) in LaFeAsO(1-x)Fx with inelastic neutron scattering methods. The PDOS of the parent compound (x=0) is very similar to the PDOS of samples optimally doped with fluorine to achieve the maximum...

Static and dynamic magnetism in underdoped superconductor BaFe1.92Co0.08As2.

Physical review letters

Christianson AD, Lumsden MD, Nagler SE, MacDougall GJ, McGuire MA, Sefat AS, Jin R, Sales BC, Mandrus D.
PMID: 19792749
Phys Rev Lett. 2009 Aug 21;103(8):087002. doi: 10.1103/PhysRevLett.103.087002. Epub 2009 Aug 19.

We report neutron scattering measurements on single crystals of BaFe1.92Co0.08As2. The magnetic Bragg peak intensity is reduced by 6% upon cooling through TC. The spin dynamics exhibit a gap of 8 meV with anisotropic three-dimensional interactions. Below TC additional...

Unusual relationship between magnetism and superconductivity in FeTe(0.5)Se(0.5).

Physical review letters

Mook HA, Lumsden MD, Christianson AD, Nagler SE, Sales BC, Jin R, McGuire MA, Sefat AS, Mandrus D, Egami T, dela Cruz C.
PMID: 20482201
Phys Rev Lett. 2010 May 07;104(18):187002. doi: 10.1103/PhysRevLett.104.187002. Epub 2010 May 06.

We use neutron scattering to study magnetic excitations in crystals near the ideal superconducting composition of FeTe(0.5)Se(0.5). Two types of excitations are found, a resonance at (0.5,0.5,0) and incommensurate fluctuations on either side of this position. We show that...

Substitution of TAG oil with diacylglycerol oil in food items improves the predicted 10 years cardiovascular risk score in healthy, overweight subjects.

Dietary fat is normally in TAG form, but diacylglycerol (DAG) is a natural component of edible oils. Studies have shown that consumption of DAG results in metabolic characteristics that are distinct from those of TAG, which may be beneficial...
