Enhancing ultraviolet spontaneous emission with a designed quantum vacuum: erratum.

Optics express

McArthur D, Hourahine B, Papoff F.
PMID: 29041771
Opt Express. 2017 Aug 21;25(17):20950-20951. doi: 10.1364/OE.25.020950.

We present a correction to parts of Fig. 5, Fig. 6 and Fig. 7, relating to the Purcell factors and Lamb shifts, due to an incorrect renormalization used in our custom Fortran code. The resulting corrections to some of...

Plasmon modes in single gold nanodiscs.

Optics express

Imura K, Ueno K, Misawa H, Okamoto H, McArthur D, Hourahine B, Papoff F.
PMID: 24921339
Opt Express. 2014 May 19;22(10):12189-99. doi: 10.1364/OE.22.012189.

Optical properties of single gold nanodiscs were studied by scanning near-field optical microscopy. Near-field transmission spectra of a single nanodisc exhibited multiple plasmon resonances in the visible to near-infrared region. Near-field transmission images observed at these resonance wavelengths show...

An Attempt to Interpret the Spread of Element Concentration in Antarctic Surface Snow: The Same Element in a Given Test Field, Several Elements in Different Sampling Fields.

Microchemical journal : devoted to the application of microtechniques in all branches of science

Lanza F, Bocci F, Papoff P.
PMID: 8979958
Microchem J. 1996 Nov;54(4):429-43. doi: 10.1006/mchj.1996.0120.

Sampling surface snow on a large test field always leads to a spread of analyte concentration data which partly follows a Gaussian distribution and partly a rectangular one as can be observed from the analysis of literature data. The...

Non-dispersive atomic-fluorescence spectrometric determination of lead by the hydride-generation technique.

Talanta

D'livo A, Papoff P.
PMID: 18963863
Talanta. 1985 May;32(5):383-6. doi: 10.1016/0039-9140(85)80102-8.

Non-dispersive atomic-fluorescence spectrometry combined with hydride-generation has been developed for lead determination. A radiofrequency-excited electrodeless discharge lamp was used as light-source and a small argon-hydrogen flame as atomizer. The detection limit was 0.06ng/ml and the linear calibration graph was...

Average patterns and coherent phenomena in wide aperture lasers.

Physical review. E, Statistical, nonlinear, and soft matter physics

D'Alessandro G, Papoff F, Louvergneaux E, Glorieux P.
PMID: 15244713
Phys Rev E Stat Nonlin Soft Matter Phys. 2004 Jun;69(6):066212. doi: 10.1103/PhysRevE.69.066212. Epub 2004 Jun 15.

Using a realistic model of wide aperture, weakly astigmatic lasers we develop a framework to analyze experimental average intensity patterns. We use the model to explain the appearance of patterns in terms of the modes of the cavity and...

Signal amplification and control in optical cavities with off-axis feedback.

Physical review letters

Zambrini R, Papoff F.
PMID: 17930828
Phys Rev Lett. 2007 Aug 10;99(6):063907. doi: 10.1103/PhysRevLett.99.063907. Epub 2007 Aug 09.

We consider a large class of optical cavities and gain media with an off-axis external feedback which introduces a two-point nonlocality. This nonlocality moves the lasing threshold and opens large windows of control parameters where weak light spots can...

Developing a standardized approach to the assessment of pain in children and youth presenting to pediatric rheumatology providers: a Delphi survey and consensus conference process followed by feasibility testing.

Pediatric rheumatology online journal

Stinson JN, Connelly M, Jibb LA, Schanberg LE, Walco G, Spiegel LR, Tse SM, Chalom EC, Chira P, Rapoff M.
PMID: 22490427
Pediatr Rheumatol Online J. 2012 Apr 10;10(1):7. doi: 10.1186/1546-0096-10-7.

BACKGROUND: Pain in children with rheumatic conditions such as arthritis is common. However, there is currently no standardized method for the assessment of this pain in children presenting to pediatric rheumatologists. A more consistent and comprehensive approach is needed...

Characterization of epithelial-mesenchymal transition intermediate/hybrid phenotypes associated to resistance to EGFR inhibitors in non-small cell lung cancer cell lines.

Oncotarget

Fustaino V, Presutti D, Colombo T, Cardinali B, Papoff G, Brandi R, Bertolazzi P, Felici G, Ruberti G.
PMID: 29262566
Oncotarget. 2017 Sep 22;8(61):103340-103363. doi: 10.18632/oncotarget.21132. eCollection 2017 Nov 28.

Increasing evidence points to a key role played by epithelial-mesenchymal transition (EMT) in cancer progression and drug resistance. In this study, we used

Smart membranes by electron beam cross-linking of copolymer microgels.

Soft matter

Bookhold J, Dirksen M, Wiehemeier L, Knust S, Anselmetti D, Paneff F, Zhang X, Gölzhäuser A, Kottke T, Hellweg T.
PMID: 33459755
Soft Matter. 2021 Mar 04;17(8):2205-2214. doi: 10.1039/d0sm02041a.

Poly(N-isopropylacrylamide) (pNIPAM) based copolymer microgels were used to create free-standing, transferable, thermoresponsive membranes. The microgels were synthesized by copolymerization of NIPAM with N-benzylhydrylacrylamide (NBHAM). Monolayers of these colloidal gels were subsequently cross-linked using an electron gun leading to the...

Renormalization flow of a weak extended backscattering Hamiltonian in a non-chiral Tomonaga-Luttinger liquid.

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

Popoff A, Lebedev AV, Raymond L, Jonckheere T, Rech J, Martin T.
PMID: 33339009
J Phys Condens Matter. 2021 Mar 17;33(11):115602. doi: 10.1088/1361-648X/abd525.

We consider a non-chiral Luttinger liquid in the presence of a backscattering Hamiltonian which has an extended range. Right/left moving fermions at a given location can thus be converted as left/right moving fermions at a different location, within a...

Structure and Biosynthesis of Myxofacyclines: Unique Myxobacterial Polyketides Featuring Varing and Rare Heterocycles.

A metabolome-guided screening approach in the novel myxobacterium Corallococcus sp. MCy9072 resulted in the isolation of the unprecedented natural product myxofacycline A, which features a rare isoxazole substructure. Identification and genomic investigation of additional producers alongside targeted gene inactivation...
