The present-day 238U/235U ratio has fundamental implications for uranium-lead geochronology and cosmochronology. A value of 137.88 has previously been considered invariant and has been used without uncertainty to calculate terrestrial mineral ages. We report high-precision 238U/235U measurements for a...

All-fiber 10 MHz acousto-optic modulator of a fiber Bragg grating at 1060 nm wavelength.

Optics express

Silva RE, Tiess T, Becker M, Eschrich T, Rothhardt M, Jäger M, Pohl AA, Bartelt H.
PMID: 26480112
Opt Express. 2015 Oct 05;23(20):25972-8. doi: 10.1364/OE.23.025972.

Acousto-optic modulation of a 1 cm fiber Bragg grating at 10.9 MHz frequency and 1065 nm wavelength is demonstrated for the first time. A special modulator design is employed to acoustically induce a dynamic radial long period grating which...

Highly efficient metal grating coupler for membrane-based integrated photonics.

Optics letters

PMID: 24784103
Opt Lett. 2014 May 01;39(9):2786-9. doi: 10.1364/OL.39.002786.

We present the design of a metal grating coupler compatible with membrane photonic circuit platforms, consisting of a buried metal grating and a metal mirror. A nonapodized design provides a fiber-to-chip coupling efficiency at 1.55 μm up to 73%,...

Unsignalled avoidance in a shuttlebox: a rapid acquisition, high-efficiency paradigm.

Journal of the experimental analysis of behavior

Riess D, Farrar CH.
PMID: 16811614
J Exp Anal Behav. 1972 Jul;18(1):169-78. doi: 10.1901/jeab.1972.18-169.

Detailed descriptive data are provided on the free-operant avoidance behavior of rats in a shuttlebox during both acquisition and terminal performance. Initially, eighteen 21-min acquisition sessions were given. Each hurdle-cross postponed the next shock 20 sec (response-shock interval) and...

Control of tantrum behavior by operant techniques during experimental verbal training.

Journal of applied behavior analysis

Sailor W, Guess D, Rutherford G, Baer DM.
PMID: 16795181
J Appl Behav Anal. 1968;1(3):237-43. doi: 10.1901/jaba.1968.1-237.

A technique of controlling undesirable or disruptive behavior during an ongoing program of verbal training with a retardate is described. The technique required that the stimulus materials of the verbal training program be graded according to difficulty, i.e., in...

Science. 2010 Jun 25;328(5986):1658-62. doi: 10.1126/science.1189401.

Photoemission from atoms is assumed to occur instantly in response to incident radiation and provides the basis for setting the zero of time in clocking atomic-scale electron motion. We used attosecond metrology to reveal a delay of 21 +/-...

Magnetic-field-induced soft-mode quantum phase transition in the high-temperature superconductor La1.855Sr0.145CuO4: an inelastic neutron-scattering study.

Physical review letters

Chang J, Christensen NB, Niedermayer Ch, Lefmann K, Rønnow HM, McMorrow DF, Schneidewind A, Link P, Hiess A, Boehm M, Mottl R, Pailhés S, Momono N, Oda M, Ido M, Mesot J.

Inelastic neutron-scattering experiments on the high-temperature superconductor La1.855Sr0.145CuO4 reveal a magnetic excitation gap Delta that decreases continuously upon application of a magnetic field perpendicular to the CuO2 planes. The gap vanishes at the critical field required to induce long-range...

2D-gel Electrophoresis As a Tool to Investigate the Composition of CD95 DISC.

Acta naturae

Riess D, Lavrik I.
PMID: 22649647
Acta Naturae. 2010 Jul;2(2):96-102.

Stimulation of CD95 (APO-1/Fas) leads to apoptosis induction in multicellular organisms. CD95-mediated apoptosis starts with the formation of the protein complex at the receptor CD95 (APO-1/Fas), which was named DISC (death-inducing signaling complex). In this work, the composition of...
