BACKGROUND: Salvage radiotherapy (SRT) has been successfully used for recurrent prostate cancer after radical prostatectomy; however, the optimal timing of SRT remains controversial. Our objective was to identify the risk factors for disease progression after SRT, with a focus...

Orbital Angular Momentum (OAM) of Rotating Modes Driven by Electrons in Electron Cyclotron Masers.

Scientific reports

Sawant A, Choe MS, Thumm M, Choi E.
PMID: 28611352
Sci Rep. 2017 Jun 13;7(1):3372. doi: 10.1038/s41598-017-03533-y.

The well-defined orbital angular momentum (OAM) of rotating cavity modes operating near the cutoff frequency excited by gyrating electrons in a high-power electron cyclotron maser (ECM)-a gyrotron-has been derived by photonic and electromagnetic wave approaches. A mode generator was...

A six-step total synthesis of α-thujone and d.

Chemical communications (Cambridge, England)

Thamm I, Richers J, Rychlik M, Tiefenbacher K.
PMID: 27709180
Chem Commun (Camb). 2016 Sep 22;52(78):11701-11703. doi: 10.1039/c6cc05376a.

The short synthesis of α-thujone relies on the functionalization of the readily available dimethylfulvene. Furthermore, the three main metabolites of the natural product were also synthesized. Since d

Multinuclear metal nucleobase complexes.

Metal-based drugs

Schreiber A, Rauter H, Krumm M, Menzer S, Hillgeris EC, Lippert B.
PMID: 18476236
Met Based Drugs. 1994;1(2):241-6. doi: 10.1155/MBD.1994.241.

Of all properties of metal nucleobase complexes, formation of multinuclear species appears to be an outstanding feature. After a brief introduction into well known polymeric metal nucleobase complexes, three aspects recently Studied in our laboratory will be dealt with...

A low-cost, linear, DC - 35 MHz, high-power LED driver for continuous wave (CW) and fluorescence lifetime imaging (FLIM).

Proceedings of SPIE--the International Society for Optical Engineering

Gioux S, Kianzad V, Ciocan R, Choi HS, Nelson C, Thumm J, Filkins RJ, Lomnes SJ, Frangioni JV.
PMID: 19655029
Proc SPIE Int Soc Opt Eng. 2008;6848:684807. doi: 10.1117/12.779196.

Near-infrared (NIR) fluorescence has the potential to provide surgeons with real-time intraoperative image-guidance. Increasing the signal-to-background ratio of fluorescent agents involves delivering a controllable excitation fluence rate of proper wavelength and/or using complementary imaging techniques such as FLIM. In...

Experimental and theoretical studies of a coaxial free-electron maser based on two-dimensional distributed feedback.

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

Konoplev IV, Cross AW, Phelps AD, He W, Ronald K, Whyte CG, Robertson CW, MacInnes P, Ginzburg NS, Peskov NY, Sergeev AS, Zaslavsky VY, Thumm M.

The first operation of a coaxial free-electron maser (FEM) based on two-dimensional (2D) distributed feedback has been recently observed. Analytical and numerical modeling, as well as measurements, of microwave radiation generated by a FEM with a cavity defined by...

How companion animals contribute to the fight against cancer in humans.

Veterinaria italiana

Thamm D, Dow S.
PMID: 20391394
Vet Ital. 2009 Jan-Mar;45(1):111-20.

Companion animals and their human guardians suffer from many of the same types of cancer and are often treated with many of the same drugs. Moreover, the overall tumour biology is much more similar between humans and companion animals...

Electron-nuclear energy sharing in above-threshold multiphoton dissociative ionization of H2.

Physical review letters

Wu J, Kunitski M, Pitzer M, Trinter F, Schmidt LP, Jahnke T, Magrakvelidze M, Madsen CB, Madsen LB, Thumm U, Dörner R.
PMID: 23889391
Phys Rev Lett. 2013 Jul 12;111(2):023002. doi: 10.1103/PhysRevLett.111.023002. Epub 2013 Jul 09.

We report experimental observation of the energy sharing between electron and nuclei in above-threshold multiphoton dissociative ionization of H2 by strong laser fields. The absorbed photon energy is shared between the ejected electron and nuclei in a correlated fashion,...

Attosecond time-resolved photoelectron dispersion and photoemission time delays.

Physical review letters

Liao Q, Thumm U.
PMID: 24484011
Phys Rev Lett. 2014 Jan 17;112(2):023602. doi: 10.1103/PhysRevLett.112.023602. Epub 2014 Jan 14.

We compute spectrograms and relative time delays for laser-assisted photoemission by single attosecond extreme ultraviolet pulses from valence band (VB) and 2p core levels (CLs) of a Mg(0001) surface within a quantum-mechanical model. Comparing the time-dependent dispersion of photoelectron...

Reconstitution of the tonoplast amino-acid carrier into liposomes : Evidence for an ATP-regulated carrier in different species.

PMID: 24186536
Planta. 1991 Nov;185(4):569-75. doi: 10.1007/BF00202968.

The tonoplast amino-acid transporter of barley (Hordeum vulgare L.) mesophyll cells was functionally reconstituted by incorporating solubilized tonoplast membranes, vacuoplast membranes or tonoplast-enriched microsomal vesicles into phosphatidylcholine liposomes. (i) Time-, concentration- and ATP-dependence of amino-acid uptake were similar to...
