A prospective randomised study comparing oral .

e-SPEN journal

Awad S, Cui H, Wright JW, Jackson S, Macdonald IA, Lobo DN.
PMID: 24834380
ESPEN J. 2012 Feb 01;7(1):e1-e4. doi: 10.1016/j.eclnm.2011.12.009.

BACKGROUND AND AIMS: Accurate assessment of energy expenditure (EE) is important in guiding nutritional therapy but current methods are unsatisfactory. This study compared the oral METHODS: Ten overnight-fasted healthy male volunteers were randomised to studies at rest or mild...

Precise half-life measurement for the superallowed 0(+)-->0(+) beta emitter (74)Rb: first results from the new radioactive beam facility (ISAC) at TRIUMF.

Physical review letters

Ball GC, Bishop S, Behr JA, Boisvert GC, Bricault P, Cerny J, D'Auria JM, Dombsky M, Hardy JC, Iacob V, Leslie JR, Lindner T, Macdonald JA, Mak HB, Moltz DM, Powell J, Savard G, Towner IS.
PMID: 11290166
Phys Rev Lett. 2001 Feb 19;86(8):1454-7. doi: 10.1103/PhysRevLett.86.1454.

Presently, the world data for superallowed beta decay leads to a result in disagreement (at the 98% confidence level) with the predictions of the minimal standard model for the unitarity of the Cabibbo-Kobayashi-Maskawa matrix. Precise data for the superallowed...

Is there a dc Josephson effect in bilayer quantum Hall systems?.

Physical review letters

Joglekar YN, MacDonald AH.
PMID: 11690440
Phys Rev Lett. 2001 Nov 05;87(19):196802. doi: 10.1103/PhysRevLett.87.196802. Epub 2001 Oct 17.

We argue on the basis of phenomenological and microscopic considerations that there is no dc Josephson effect in ordered bilayer quantum Hall systems, even at T = 0. Instead the tunnel conductance is strongly enhanced, approaching a finite value...

Interdimensional interference in the Stroop effect: uncovering the cognitive and neural anatomy of attention.

Trends in cognitive sciences

MacLeod CM, MacDonald PA.
PMID: 11025281
Trends Cogn Sci. 2000 Oct 01;4(10):383-391. doi: 10.1016/s1364-6613(00)01530-8.

In the classic Stroop effect, naming the color of an incompatible color word (e.g. the word RED printed in green ink; say, 'green') is much slower and more error-prone than is naming the color of a control item (e.g....

Measuring the condensate fraction of rapidly rotating trapped boson systems: off-diagonal order from the density profile.

Physical review letters

Sinova J, Hanna CB, MacDonald AH.
PMID: 12688856
Phys Rev Lett. 2003 Mar 28;90(12):120401. doi: 10.1103/PhysRevLett.90.120401. Epub 2003 Mar 24.

We demonstrate a direct connection between the density profile of a system of ultracold trapped bosonic particles in the rapid-rotation limit and its condensate fraction. This connection can be used to probe the crossover from condensed vortex-lattice states to...

Quantum melting and absence of Bose-Einstein condensation in two-dimensional vortex matter.

Physical review letters

Sinova J, Hanna CB, MacDonald AH.
PMID: 12144381
Phys Rev Lett. 2002 Jul 15;89(3):030403. doi: 10.1103/PhysRevLett.89.030403. Epub 2002 Jun 28.

We demonstrate that quantum fluctuations suppress Bose-Einstein condensation of quasi-two-dimensional bosons in a rapidly rotating trap. Our conclusions rest in part on the derivation of an exact expression for the boson action in terms of vortex position coordinates, and...

Theory of ferromagnetism in doped excitonic condensates.

Physical review letters

Bascones E, Burkov AA, MacDonald AH.
PMID: 12190486
Phys Rev Lett. 2002 Aug 19;89(8):086401. doi: 10.1103/PhysRevLett.89.086401. Epub 2002 Aug 02.

Nesting in a semimetal can lead to an excitonic-insulator state with spontaneous coherence between conduction and valence bands and a gap for charged excitations. We present a theory of the ferromagnetic state that occurs when the density of electrons...

Chern numbers for spin models of transition metal nanomagnets.

Physical review letters

Canali CM, Cehovin A, MacDonald AH.
PMID: 12906687
Phys Rev Lett. 2003 Jul 25;91(4):046805. doi: 10.1103/PhysRevLett.91.046805. Epub 2003 Jul 25.

We argue that ferromagnetic transition metal nanoparticles with fewer than approximately 100 atoms can be described by an effective Hamiltonian with a single giant spin degree of freedom. The total spin S of the effective Hamiltonian is specified by...

Hepatocellular carcinoma.

Current opinion in gastroenterology

Macdonald GA.
PMID: 17023953
Curr Opin Gastroenterol. 1999 May;15(3):253-9. doi: 10.1097/00001574-199905000-00011.

Hepatitis C infection is associated with the development of hepatocellular carcinoma, and progress has been made in a number of areas. Transgenic mice lines expressing the hepatitis C core protein develop hepatic steatosis, adenomas, and hepatocellular carcinomas, with no...
