Abstract Analysis of recent bushfires in Australia, such as Black Saturday in 2009 and the Kimberley Ultramarathon tragedy in 2011, demonstrates that a lack of communications for …

Exosome mediated growth effect on the non-growing pre-B acute lymphoblastic leukemia cells at low starting cell density.

American journal of translational research

Patel SJ, Darie CC, Clarkson BD.
PMID: 27725845
Am J Transl Res. 2016 Sep 15;8(9):3614-3629. eCollection 2016.

Tumors contain heterogeneous cell populations and achieve dominance by functioning as collective systems. The mechanisms underlying the aberrant growth and interactions between cells are not very well understood. The pre-B acute lymphoblastic leukemia cells we studied were obtained directly...

Magnetic structure and ordering of multiferroic hexagonal LuFeO_{3}.

Physical review letters

Disseler SM, Borchers JA, Brooks CM, Mundy JA, Moyer JA, Hillsberry DA, Thies EL, Tenne DA, Heron J, Holtz ME, Clarkson JD, Stiehl GM, Schiffer P, Muller DA, Schlom DG, Ratcliff WD.
PMID: 26066458
Phys Rev Lett. 2015 May 29;114(21):217602. doi: 10.1103/PhysRevLett.114.217602. Epub 2015 May 27.

We report on the magnetic structure and ordering of hexagonal LuFeO_{3} films of variable thickness grown by molecular-beam epitaxy on YSZ (111) and Al_{2}O_{3} (0001) substrates. These crystalline films exhibit long-range structural uniformity dominated by the polar P6_{3}cm phase,...

Deterministic switching of ferromagnetism at room temperature using an electric field.

Nature

Heron JT, Bosse JL, He Q, Gao Y, Trassin M, Ye L, Clarkson JD, Wang C, Liu J, Salahuddin S, Ralph DC, Schlom DG, Iñiguez J, Huey BD, Ramesh R.
PMID: 25519134
Nature. 2014 Dec 18;516(7531):370-3. doi: 10.1038/nature14004.

The technological appeal of multiferroics is the ability to control magnetism with electric field. For devices to be useful, such control must be achieved at room temperature. The only single-phase multiferroic material exhibiting unambiguous magnetoelectric coupling at room temperature...

ADAPTIVE SMALL-ANIMAL SPECT/CT.

IEEE Nuclear Science Symposium conference record. Nuclear Science Symposium

Furenlid LR, Moore JW, Freed M, Kupinski MA, Clarkson E, Liu Z, Wilson DW, Woolfenden JM, Barrett HH.
PMID: 26617457
IEEE Nucl Sci Symp Conf Rec (1997). 2008;2008:1407-1410. doi: 10.1109/ISBI.2008.4541269.

We are exploring the concept of adaptive multimodality imaging, a form of non-linear optimization where the imaging configuration is automatically adjusted in response to the object. Preliminary studies suggest that substantial improvement in objective, task-based measures of image quality...

Full Electroresistance Modulation in a Mixed-Phase Metallic Alloy.

Physical review letters

Liu ZQ, Li L, Gai Z, Clarkson JD, Hsu SL, Wong AT, Fan LS, Lin MW, Rouleau CM, Ward TZ, Lee HN, Sefat AS, Christen HM, Ramesh R.
PMID: 26991197
Phys Rev Lett. 2016 Mar 04;116(9):097203. doi: 10.1103/PhysRevLett.116.097203. Epub 2016 Mar 03.

We report a giant, ∼22%, electroresistance modulation for a metallic alloy above room temperature. It is achieved by a small electric field of 2  kV/cm via piezoelectric strain-mediated magnetoelectric coupling and the resulting magnetic phase transition in epitaxial FeRh/BaTiO_{3}...

Optimal channels for channelized quadratic estimators.

Journal of the Optical Society of America. A, Optics, image science, and vision

Kupinski MK, Clarkson E.
PMID: 27409452
J Opt Soc Am A Opt Image Sci Vis. 2016 Jun 01;33(6):1214-25. doi: 10.1364/JOSAA.33.001214.

We present a new method for computing optimized channels for estimation tasks that is feasible for high-dimensional image data. Maximum-likelihood (ML) parameter estimates are challenging to compute from high-dimensional likelihoods. The dimensionality reduction from M measurements to L channels...

Managing breaches of containment and eradication of invasive plant populations.

The Journal of applied ecology

Fletcher CS, Westcott DA, Murphy HT, Grice AC, Clarkson JR.
PMID: 25678718
J Appl Ecol. 2015 Feb;52(1):59-68. doi: 10.1111/1365-2664.12361. Epub 2014 Nov 21.

Containment can be a viable strategy for managing invasive plants, but it is not always cheaper than eradication. In many cases, converting a failed eradication programme to a containment programme is not economically justified. Despite this, many contemporary invasive...

Simulating Silicon Photomultiplier Response to Scintillation Light.

IEEE transactions on nuclear science

Jha AK, van Dam HT, Kupinski MA, Clarkson E.
PMID: 26236040
IEEE Trans Nucl Sci. 2013 Feb;30(1):336-351. doi: 10.1109/TNS.2012.2234135.

The response of a Silicon Photomultiplier (SiPM) to optical signals is affected by many factors including photon-detection efficiency, recovery time, gain, optical crosstalk, afterpulsing, dark count, and detector dead time. Many of these parameters vary with overvoltage and temperature....

Diurnal variations in hydraulic conductivity and root pressure can be correlated with the expression of putative aquaporins in the roots of lotus japonicus.

Planta

Henzler T, Waterhouse RN, Smyth AJ, Carvajal M, Cooke DT, Schaffner AR, Steudle E, Clarkson DT.
PMID: 10592032
Planta. 1999 Nov;210(1):50-60. doi: 10.1007/s004250050653.

The hydraulic conductivity of excised roots (Lp(r)) of the legume Lotus japonicus (Regel) K. Larsen grown in mist (aeroponic) and sand cultures, was found to vary over a 5-fold range during a day/night cycle. This behaviour was seen when...
