PMID: 28255255
Clin Epidemiol. 2017 Feb 17;9:105-111. doi: 10.2147/CLEP.S124454. eCollection 2017.

BACKGROUND: In Denmark, a nationwide screening program for colorectal cancer was implemented in March 2014. Along with this, a clinical database for program monitoring and research purposes was established.OBJECTIVE: The aim of this study was to estimate the agreement...

Millimeter-Scale Spatial Coherence from a Plasmon Laser.

Nano letters

Hoang TB, Akselrod GM, Yang A, Odom TW, Mikkelsen MH.
PMID: 28956442
Nano Lett. 2017 Nov 08;17(11):6690-6695. doi: 10.1021/acs.nanolett.7b02677. Epub 2017 Oct 04.

Coherent light sources have been demonstrated based on a wide range of nanostructures, however, little effort has been devoted to probing their underlying coherence properties. Here, we report long-range spatial coherence of lattice plasmon lasers constructed from a periodic...

Ultrafast spontaneous emission source using plasmonic nanoantennas.

Nature communications

Hoang TB, Akselrod GM, Argyropoulos C, Huang J, Smith DR, Mikkelsen MH.
PMID: 26212857
Nat Commun. 2015 Jul 27;6:7788. doi: 10.1038/ncomms8788.

Typical emitters such as molecules, quantum dots and semiconductor quantum wells have slow spontaneous emission with lifetimes of 1-10 ns, creating a mismatch with high-speed nanoscale optoelectronic devices such as light-emitting diodes, single-photon sources and lasers. Here we experimentally...

Maternal serum supplementation in culture medium benefits maturation of immature human oocytes.

Reproductive biomedicine online

Mikkelsen AL, Høst E, Blaabjerg J, Lindenberg S.
PMID: 12513873
Reprod Biomed Online. 2001;3(2):112-116. doi: 10.1016/s1472-6483(10)61978-5.

This study compared the rates of maturation, fertilization, cleavage and pregnancy among oocytes matured in medium containing either human serum albumin (HSA) or maternal serum. Immature oocytes were obtained from 51 consecutive regularly cycling women

Dimits shift in realistic gyrokinetic plasma-turbulence simulations.

Physical review letters

Mikkelsen DR, Dorland W.
PMID: 18851456
Phys Rev Lett. 2008 Sep 26;101(13):135003. doi: 10.1103/PhysRevLett.101.135003. Epub 2008 Sep 26.

In simulations of turbulent plasma transport due to long wavelength (k perpendicular rhoi < or = 1) electrostatic drift-type instabilities, we find a persistent nonlinear up-shift of the effective threshold. Next-generation tokamaks will likely benefit from the higher effective...

Picosecond coherent optical manipulation of a single electron spin in a quantum dot.

Science (New York, N.Y.)

Berezovsky J, Mikkelsen MH, Stoltz NG, Coldren LA, Awschalom DD.
PMID: 18420929
Science. 2008 Apr 18;320(5874):349-52. doi: 10.1126/science.1154798.

Most schemes for quantum information processing require fast single-qubit operations. For spin-based qubits, this involves performing arbitrary coherent rotations of the spin state on time scales much faster than the spin coherence time. By applying off-resonant, picosecond-scale optical pulses,...

The implications of autonomy: Viewed in the light of efforts to uphold patients dignity and integrity.

International journal of qualitative studies on health and well-being

Delmar C, Alenius-Karlsson N, Mikkelsen AH.
PMID: 21695070
Int J Qual Stud Health Well-being. 2011;6(2). doi: 10.3402/qhw.v6i2.6045. Epub 2011 May 27.

This article focuses on Danish patients' experience of autonomy and its interplay with dignity and integrity in their meeting with health professionals. The aim is to chart the meanings and implications of autonomy for persons whose illness places them...

Neuronal precursor cell proliferation in the hippocampus after transient cerebral ischemia: a comparative study of two rat strains using stereological tools.

Experimental & translational stroke medicine

Kelsen J, Larsen MH, Sørensen JC, Møller A, Frøkiaer J, Nielsen S, Nyengaard JR, Mikkelsen JD, Rønn LC.
PMID: 20370927
Exp Transl Stroke Med. 2010 Apr 06;2:8. doi: 10.1186/2040-7378-2-8.

BACKGROUND: We are currently investigating microglial activation and neuronal precursor cell (NPC) proliferation after transient middle cerebral artery occlusion (tMCAo) in rats. This study aimed: (1) to investigate differences in hippocampal NPC proliferation in outbred male spontaneously hypertensive rats...

Zero-field optical manipulation of magnetic ions in semiconductors.

Nature materials

Myers RC, Mikkelsen MH, Tang JM, Gossard AC, Flatté ME, Awschalom DD.
PMID: 18278049
Nat Mater. 2008 Mar;7(3):203-8. doi: 10.1038/nmat2123. Epub 2008 Feb 17.

Controlling and monitoring individual spins is desirable for building spin-based devices, as well as implementing quantum information processing schemes. As with trapped ions in cold gases, magnetic ions trapped on a semiconductor lattice have uniform properties and relatively long...

Adiabatically widened silicon microrings for improved variation tolerance.

Optics express

Mikkelsen JC, Sacher WD, Poon JK.
PMID: 24787851
Opt Express. 2014 Apr 21;22(8):9659-66. doi: 10.1364/OE.22.009659.

We show that silicon microrings with adiabatically widened bends are more tolerant to dimensional variations than conventional microring designs with uniform waveguide widths. Through wafer-scale measurements of test structures fabricated in the IMEC Standard Passives process (193 nm DUV...
