Jonas E, Sjöqvist S, Elbe P, Kanai N, Enger J, Haas SL, Mohkles-Barakat A, Okano T, Takagi R, Ohki T, Yamamoto M, Kondo M, Markland K, Lim ML, Yamato M, Nilsson M, Permert J, Blomberg P, Löhr JM.

United European Gastroenterol J. 2016 Dec;4(6):741-753. doi: 10.1177/2050640616631205. Epub 2016 Feb 19.

BACKGROUND AND OBJECTIVE: Endoscopic mucosal dissection (ESD) is a treatment option for oesophagus tumours localized to the mucosa enabling en bloc removal of large lesions. The resulting larger mucosal defects have resulted in an increase in the occurrence of...

Magnetospheric Multiscale Satellites Observations of Parallel Electric Fields Associated with Magnetic Reconnection.

Ergun RE, Goodrich KA, Wilder FD, Holmes JC, Stawarz JE, Eriksson S, Sturner AP, Malaspina DM, Usanova ME, Torbert RB, Lindqvist PA, Khotyaintsev Y, Burch JL, Strangeway RJ, Russell CT, Pollock CJ, Giles BL, Hesse M, Chen LJ, Lapenta G, Goldman MV, Newman DL, Schwartz SJ, Eastwood JP, Phan TD, Mozer FS, Drake J, Shay MA, Cassak PA, Nakamura R, Marklund G.
PMID: 27341241
Phys Rev Lett. 2016 Jun 10;116(23):235102. doi: 10.1103/PhysRevLett.116.235102. Epub 2016 Jun 10.

We report observations from the Magnetospheric Multiscale satellites of parallel electric fields (E_{∥}) associated with magnetic reconnection in the subsolar region of the Earth's magnetopause. E_{∥} events near the electron diffusion region have amplitudes on the order of 100...

Temporal evolution of the electric field accelerating electrons away from the auroral ionosphere.

Nature

Marklund GT, Ivchenko N, Karlsson T, Fazakerley A, Dunlop M, Lindqvist PA, Buchert S, Owen C, Taylor M, Vaivalds A, Carter P, André M, Balogh A.
PMID: 11742392
Nature. 2001 Dec 13;414(6865):724-7. doi: 10.1038/414724a.

The bright night-time aurorae that are visible to the unaided eye are caused by electrons accelerated towards Earth by an upward-pointing electric field. On adjacent geomagnetic field lines the reverse process occurs: a downward-pointing electric field accelerates electrons away...

Electromagnetic wave collapse in a radiation background.

Physical review letters

Marklund M, Brodin G, Stenflo L.
PMID: 14611403
Phys Rev Lett. 2003 Oct 17;91(16):163601. doi: 10.1103/PhysRevLett.91.163601. Epub 2003 Oct 16.

The nonlinear interaction, due to quantum electrodynamical (QED) effects between an electromagnetic pulse and a radiation background, is investigated by combining the methods of radiation hydrodynamics with the QED theory for photon-photon scattering. For the case of a single...

Single particle X-ray diffractive imaging.

Nano letters

Bogan MJ, Benner WH, Boutet S, Rohner U, Frank M, Barty A, Seibert MM, Maia F, Marchesini S, Bajt S, Woods B, Riot V, Hau-Riege SP, Svenda M, Marklund E, Spiller E, Hajdu J, Chapman HN.
PMID: 18095739
Nano Lett. 2008 Jan;8(1):310-6. doi: 10.1021/nl072728k. Epub 2007 Dec 21.

In nanotechnology, strategies for the creation and manipulation of nanoparticles in the gas phase are critically important for surface modification and substrate-free characterization. Recent coherent diffractive imaging with intense femtosecond X-ray pulses has verified the capability of single-shot imaging...

Quantum-electrodynamical photon splitting in magnetized nonlinear pair plasmas.

Physical review letters

Brodin G, Marklund M, Eliasson B, Shukla PK.
PMID: 17501131
Phys Rev Lett. 2007 Mar 23;98(12):125001. doi: 10.1103/PhysRevLett.98.125001. Epub 2007 Mar 20.

We present for the first time the nonlinear dynamics of quantum electrodynamic (QED) photon splitting in a strongly magnetized electron-positron (pair) plasma. By using a QED corrected Maxwell equation, we derive a set of equations that exhibit nonlinear couplings...

Suppression of nonlinear effects by phase alternation in strongly dispersion-managed optical transmission.

Optics letters

Johannisson P, Anderson D, Marklund M, Berntson A, Forzati M, Mårtensson J.
PMID: 18026369
Opt Lett. 2002 Jun 15;27(12):1073-5. doi: 10.1364/ol.27.001073.

The nonlinear effects of amplitude jitter and ghost pulse generation, which are present in strongly dispersion-managed optical communication systems can be suppressed by alternation of the phase of the bits. A physical explanation for this effect is given that...

Amyloid-β Peptides and Tau Protein as Biomarkers in Cerebrospinal and Interstitial Fluid Following Traumatic Brain Injury: A Review of Experimental and Clinical Studies.

Frontiers in neurology

Tsitsopoulos PP, Marklund N.
PMID: 23805125
Front Neurol. 2013 Jun 26;4:79. doi: 10.3389/fneur.2013.00079. eCollection 2013.

Traumatic brain injury (TBI) survivors frequently suffer from life-long deficits in cognitive functions and a reduced quality of life. Axonal injury, observed in many severe TBI patients, results in accumulation of amyloid precursor protein (APP). Post-injury enzymatic cleavage of...

Spin contribution to the ponderomotive force in a plasma.

Physical review letters

Brodin G, Misra AP, Marklund M.
PMID: 20867527
Phys Rev Lett. 2010 Sep 03;105(10):105004. doi: 10.1103/PhysRevLett.105.105004. Epub 2010 Sep 03.

The concept of a ponderomotive force due to the intrinsic spin of electrons is developed. An expression containing both the classical as well as the spin-induced ponderomotive force is derived. The results are used to demonstrate that an electromagnetic...

Facilitated assessment of tissue loss following traumatic brain injury.

Frontiers in neurology

Hånell A, Hedin J, Clausen F, Marklund N.
PMID: 22435063
Front Neurol. 2012 Mar 14;3:29. doi: 10.3389/fneur.2012.00029. eCollection 2012.

All experimental models of traumatic brain injury (TBI) result in a progressive loss of brain tissue. The extent of tissue loss reflects the injury severity and can be measured to evaluate the potential neuroprotective effect of experimental treatments. Quantitation...
