Competition between a fractional quantum hall liquid and bubble and Wigner crystal phases in the third Landau level.

Physical review letters

Gervais G, Engel LW, Stormer HL, Tsui DC, Baldwin KW, West KW, Pfeiffer LN.
PMID: 15698005
Phys Rev Lett. 2004 Dec 31;93(26):266804. doi: 10.1103/PhysRevLett.93.266804. Epub 2004 Dec 21.

Magnetotransport measurements were performed in an ultrahigh mobility GaAs/AlGaAs quantum well of density approximately 3.0 x 10(11) cm(-2). The temperature dependence of the magnetoresistance Rxx was studied in detail in the vicinity of nu=9/2. In particular, we discovered new...

Pinning modes and interlayer correlation in high-magnetic-field bilayer Wigner solids.

Physical review letters

Wang Z, Chen YP, Engel LW, Tsui DC, Tutuc E, Shayegan M.
PMID: 17930621
Phys Rev Lett. 2007 Sep 28;99(13):136804. doi: 10.1103/PhysRevLett.99.136804. Epub 2007 Sep 26.

We report studies of pinning mode resonances in the low total Landau filling (nu) Wigner solid of a series of bilayer hole samples with negligible interlayer tunneling and with varying interlayer separation d. Comparison of states with equal layer...

Sinus floor augmentation using miniscrew and in situ hardening biomaterial: method and case report.

International journal of clinical and experimental medicine

Engelke W, Fuentes R, Beltrán V.
PMID: 25035787
Int J Clin Exp Med. 2014 Jun 15;7(6):1607-10. eCollection 2014.

Sinus floor augmentation in case of severe pneumatization is a challenge for surgical management. We present a low invasive endoscopically assisted technique facilitating the stabilization of augmentation material in the subantral space. The technique consists of (1) trepanation of...

A compact source condition for modelling focused fields using the pseudospectral time-domain method.

Optics express

Munro PR, Engelke D, Sampson DD.
PMID: 24663901
Opt Express. 2014 Mar 10;22(5):5599-613. doi: 10.1364/OE.22.005599.

The pseudospectral time-domain (PSTD) method greatly extends the physical volume of biological tissue in which light scattering can be calculated, relative to the finite-difference time-domain (FDTD) method. We have developed an analogue of the total-field scattered-field source condition, as...

Dynamics of beta-CH and beta-CH2 Groups of Amino Acid Side Chains in Proteins.

Journal of biomolecular NMR

Engelke J, Rüterjans H.
PMID: 20700827
J Biomol NMR. 1998 Feb;11(2):165-83. doi: 10.1023/A:1008251319019.

The dynamics of amino acid side chains of uniformly 13C/15N-enriched ribonuclease T1 (RNase T1) have been investigated. Heteronuclear longitudinal relaxation rates, 1H/13C NOEs, and transverse cross-correlated cross-relaxation rates between the Sx and the SxIz1Iz2 operators (SIIS cross relaxation) [Ernst...

Thin film MnGe grown on Si(111).

Journal of physics. Condensed matter : an Institute of Physics journal

Engelke J, Menzel D, Dyadkin VA.
PMID: 24150729
J Phys Condens Matter. 2013 Nov 27;25(47):472201. doi: 10.1088/0953-8984/25/47/472201. Epub 2013 Oct 23.

MnGe has been grown as a thin film on Si(111) substrates by molecular beam epitaxy. A 10 Å layer of MnSi was used as the seed layer in order to establish the B20 crystal structure. Films of a thickness...

Short-Term Metallothionein and Copper Changes in Blue Crabs at Ecdysis.

The Biological bulletin

Engel DW, Brouwer M.
PMID: 29304652
Biol Bull. 1991 Jun;180(3):447-452. doi: 10.2307/1542345.

We have previously demonstrated that the small metal-binding protein, metallothionein (MT), plays an important role in the metabolism of Cu and Zn during the molt cycle of the blue crab, Callinectes sapidus. To further delineate the role of MT...

Element Specificity of Transient Extreme Ultraviolet Magnetic Dichroism.

Physical review letters

Dewhurst JK, Willems F, Elliott P, Li QZ, Schmising CVK, Strüber C, Engel DW, Eisebitt S, Sharma S.
PMID: 32142343
Phys Rev Lett. 2020 Feb 21;124(7):077203. doi: 10.1103/PhysRevLett.124.077203.

In this work we combine theory and experiment to study transient magnetic circular dichroism (TRMCD) in the extreme ultraviolet spectral range in bulk Co and CoPt. We use the ab initio method of real-time time-dependent density functional theory to...

Overcoming Volume Selectivity of Dipolar Recoupling in Biological Solid-State NMR Spectroscopy.

Angewandte Chemie (International ed. in English)

Tošner Z, Sarkar R, Becker-Baldus J, Glaubitz C, Wegner S, Engelke F, Glaser SJ, Reif B.
PMID: 29989288

Dipolar recoupling in solid-state NMR is an essential method for establishing correlations between nuclei that are close in space. In applications on protein samples, the traditional experiments like ramped and adiabatic DCP suffer from the fact that dipolar recoupling...

Proteome-wide associations with short- and long-term weight loss and regain after Roux-en-Y gastric bypass surgery.

OBJECTIVE: Gastric bypass surgery results in long-term weight loss. Small studies have examined protein changes during rapid weight loss (up to 1 or 2 years post surgery). This study tested whether short-term changes were maintained after 12 years.METHODS: A...
