Imaging the Fano lattice to 'hidden order' transition in URu(2)Si(2).

Nature

Schmidt AR, Hamidian MH, Wahl P, Meier F, Balatsky AV, Garrett JD, Williams TJ, Luke GM, Davis JC.
PMID: 20520706
Nature. 2010 Jun 03;465(7298):570-6. doi: 10.1038/nature09073.

Within a Kondo lattice, the strong hybridization between electrons localized in real space (r-space) and those delocalized in momentum-space (k-space) generates exotic electronic states called 'heavy fermions'. In URu(2)Si(2) these effects begin at temperatures around 55 K but they...

Beam forming of the underwater sound field from impact pile driving.

The Journal of the Acoustical Society of America

Dahl PH, Reinhall PG.
PMID: 23862896
J Acoust Soc Am. 2013 Jul;134(1):EL1-6. doi: 10.1121/1.4807430.

Observations of underwater noise from impact pile driving were made with a vertical line array. Previous studies [Reinhall and Dahl, J. Acoust. Soc. Am. 130, 1209-1216 (2011)] show that the dominant underwater noise from impact driving is from the...

Estimating the evidence of selection and the reliability of inference in unigenic evolution.

Algorithms for molecular biology : AMB

Fernandes AD, Kleinstiver BP, Edgell DR, Wahl LM, Gloor GB.
PMID: 21059250
Algorithms Mol Biol. 2010 Nov 08;5:35. doi: 10.1186/1748-7188-5-35.

BACKGROUND: Unigenic evolution is a large-scale mutagenesis experiment used to identify residues that are potentially important for protein function. Both currently-used methods for the analysis of unigenic evolution data analyze 'windows' of contiguous sites, a strategy that increases statistical...

Adjoint-enabled optimization of optical devices based on coupled-mode equations.

Optics express

Lefevre Y, Wahl P, Vermeulen N, Thienpont H.
PMID: 25321026
Opt Express. 2014 Aug 11;22(16):19423-39. doi: 10.1364/OE.22.019423.

In this work, we propose a method for designing optical devices described by coupled-mode equations. Following a commonly applied optimization strategy, we combine gradient-based optimization algorithms with an adjoint sensitivity analysis of the coupled-mode equations to obtain an optimization...

Construction and performance of a dilution-refrigerator based spectroscopic-imaging scanning tunneling microscope.

The Review of scientific instruments

Singh UR, Enayat M, White SC, Wahl P.
PMID: 23387660
Rev Sci Instrum. 2013 Jan;84(1):013708. doi: 10.1063/1.4788941.

We report on the set-up and performance of a dilution-refrigerator based spectroscopic imaging scanning tunneling microscope. It operates at temperatures below 10 mK and in magnetic fields up to 14T. The system allows for sample transfer and in situ...

Repositioning and stabilization of the radial styloid process in comminuted fractures of the distal radius using a single approach: the radio-volar double plating technique.

Journal of orthopaedic surgery and research

Jacobi M, Wahl P, Kohut G.
PMID: 20701799
J Orthop Surg Res. 2010 Aug 11;5:55. doi: 10.1186/1749-799X-5-55.

BACKGROUND: A possible difficulty in intra-articular fracture of the distal radius is the displacement tendency of the radial styloid process due to the tension of the brachioradialis tendon.METHODS: Ten patients treated within one year for complex distal radius fractures...

INTRODUCTION: Local application of antibiotics provides high concentrations at the site of interest, with minimal systemic toxicity. Carrier materials might help manage dead space. Calcium sulphate (CaSOMETHODS: CaSORESULTS: Piperacillin-tazobactam, ceftazidime, cefepime, and meropenem showed fast reduction of concentration and...

Boron-Incorporating Silicon Nanocrystals Embedded in SiO.

Scientific reports

Hiller D, López-Vidrier J, Gutsch S, Zacharias M, Wahl M, Bock W, Brodyanski A, Kopnarski M, Nomoto K, Valenta J, König D.
PMID: 28827565
Sci Rep. 2017 Aug 21;7(1):8337. doi: 10.1038/s41598-017-08814-0.

Boron (B) doping of silicon nanocrystals requires the incorporation of a B-atom on a lattice site of the quantum dot and its ionization at room temperature. In case of successful B-doping the majority carriers (holes) should quench the photoluminescence...

Compositional analysis of the association between mortality and 24-hour movement behaviour from NHANES.

European journal of preventive cardiology

McGregor DE, Palarea-Albaladejo J, Dall PM, Del Pozo Cruz B, Chastin SF.
PMID: 31382810
Eur J Prev Cardiol. 2019 Aug 05;2047487319867783. doi: 10.1177/2047487319867783. Epub 2019 Aug 05.

AIMS: Previous prospective studies of the association between mortality and physical activity have generally not fully accounted for the interplay between movement behaviours. A compositional data modelling approach accounts for relative scale and co-dependency in time-use data across physical...

We study the low-energy surface electronic structure of the transition-metal dichalcogenide superconductor PdTe_{2} by spin- and angle-resolved photoemission, scanning tunneling microscopy, and density-functional theory-based supercell calculations. Comparing PdTe_{2} with its sister compound PtSe_{2}, we demonstrate how enhanced interlayer hopping...
