Surrogate endpoints: a basis for a rational approach.

European journal of clinical pharmacology

Boissel JP, Collet JP, Moleur P, Haugh M.
PMID: 1425885
Eur J Clin Pharmacol. 1992;43(3):235-44. doi: 10.1007/BF02333016.

In clinical trials, the clinical endpoint is often replaced by an intermediate endpoint, known in some instances as a "surrogate" endpoint. The reasons for the substitution are often both practical and financial. At present, no theoretical basis or practical...

[Clinical trials in general practice. The telematics solution].

Therapie

Boissel JP, Alamercery Y, Collet JP, Luciani J, Leizorovicz A.
PMID: 2080485
Therapie. 1990 Nov-Dec;45(6):471-4.

Clinical trials with private practitioners pose a series of specific problems. Among them, the large number of investigators, the scarcity of time that each investigator can allocate to the study, may be eased by using computerized network. The telematic...

Performance of a beam-multiplexing diamond crystal monochromator at the Linac Coherent Light Source.

The Review of scientific instruments

Zhu D, Feng Y, Stoupin S, Terentyev SA, Lemke HT, Fritz DM, Chollet M, Glownia JM, Alonso-Mori R, Sikorski M, Song S, van Driel TB, Williams GJ, Messerschmidt M, Boutet S, Blank VD, Shvyd'ko YV, Robert A.

Rev Sci Instrum. 2014 Jun;85(6):063106. doi: 10.1063/1.4880724.

A double-crystal diamond monochromator was recently implemented at the Linac Coherent Light Source. It enables splitting pulses generated by the free electron laser in the hard x-ray regime and thus allows the simultaneous operations of two instruments. Both monochromator...

Spectral encoding method for measuring the relative arrival time between x-ray/optical pulses.

The Review of scientific instruments

Bionta MR, Hartmann N, Weaver M, French D, Nicholson DJ, Cryan JP, Glownia JM, Baker K, Bostedt C, Chollet M, Ding Y, Fritz DM, Fry AR, Kane DJ, Krzywinski J, Lemke HT, Messerschmidt M, Schorb S, Zhu D, White WE, Coffee RN.
PMID: 25173255
Rev Sci Instrum. 2014 Aug;85(8):083116. doi: 10.1063/1.4893657.

The advent of few femtosecond x-ray light sources brings promise of x-ray/optical pump-probe experiments that can measure chemical and structural changes in the 10-100 fs time regime. Widely distributed timing systems used at x-ray Free-Electron Laser facilities are typically...

Direct characterization of photoinduced lattice dynamics in BaFe2As2.

Nature communications

Gerber S, Kim KW, Zhang Y, Zhu D, Plonka N, Yi M, Dakovski GL, Leuenberger D, Kirchmann PS, Moore RG, Chollet M, Glownia JM, Feng Y, Lee JS, Mehta A, Kemper AF, Wolf T, Chuang YD, Hussain Z, Kao CC, Moritz B, Shen ZX, Devereaux TP, Lee WS.
PMID: 26051704
Nat Commun. 2015 Jun 08;6:7377. doi: 10.1038/ncomms8377.

Ultrafast light pulses can modify electronic properties of quantum materials by perturbing the underlying, intertwined degrees of freedom. In particular, iron-based superconductors exhibit a strong coupling among electronic nematic fluctuations, spins and the lattice, serving as a playground for...

The interactions between electrons and lattice vibrations are fundamental to materials behaviour. In the case of group IV-VI, V and related materials, these interactions are strong, and the materials exist near electronic and structural phase transitions. The prototypical example...

We study the structural dynamics of photoexcited [Co(terpy)_{2}]^{2+} in an aqueous solution with ultrafast x-ray diffuse scattering experiments conducted at the Linac Coherent Light Source. Through direct comparisons with density functional theory calculations, our analysis shows that the photoexcitation...
