A Historical View of Motion Sickness-A Plague at Sea and on Land, Also with Military Impact.

Frontiers in neurology

Huppert D, Benson J, Brandt T.
PMID: 28421029
Front Neurol. 2017 Apr 04;8:114. doi: 10.3389/fneur.2017.00114. eCollection 2017.

Seasickness and its triggers, symptoms, and preventive measures were well known in antiquity. This chapter is based on an analysis of descriptions of motion sickness, in particular seasickness, in ancient Greek, Roman, and Chinese literature. A systematic search was...

High-bandwidth multimode self-sensing in bimodal atomic force microscopy.

Beilstein journal of nanotechnology

Ruppert MG, Moheimani SO.
PMID: 26977385
Beilstein J Nanotechnol. 2016 Feb 24;7:284-95. doi: 10.3762/bjnano.7.26. eCollection 2016.

Using standard microelectromechanical system (MEMS) processes to coat a microcantilever with a piezoelectric layer results in a versatile transducer with inherent self-sensing capabilities. For applications in multifrequency atomic force microscopy (MF-AFM), we illustrate that a single piezoelectric layer can...

Photoelectron spectrometer for attosecond spectroscopy of liquids and gases.

The Review of scientific instruments

Jordan I, Huppert M, Brown MA, van Bokhoven JA, Wörner HJ.
PMID: 26724045
Rev Sci Instrum. 2015 Dec;86(12):123905. doi: 10.1063/1.4938175.

A new apparatus for attosecond time-resolved photoelectron spectroscopy of liquids and gases is described. It combines a liquid microjet source with a magnetic-bottle photoelectron spectrometer and an actively stabilized attosecond beamline. The photoelectron spectrometer permits venting and pumping of...

Metal Linkage Effects on Ultrafast Energy Transfer.

Chemistry (Weinheim an der Bergstrasse, Germany)

Dekkiche H, Buisson A, Langlois A, Karsenti PL, Ruhlmann L, Ruppert R, Harvey P.
PMID: 27333487
Chemistry. 2016 Jul 18;22(30):10484-93. doi: 10.1002/chem.201601322. Epub 2016 Jun 22.

We report the preparation of several new porphyrin homodimers bridged by a platinum(II) ion in which very intense electronic communication through the coordination link occurs. Moreover, the synthesis of a new porphyrin dyad and its photophysical properties are reported....

Multimodal cantilevers with novel piezoelectric layer topology for sensitivity enhancement.

Beilstein journal of nanotechnology

Moore SI, Ruppert MG, Yong YK.
PMID: 28326225
Beilstein J Nanotechnol. 2017 Feb 06;8:358-371. doi: 10.3762/bjnano.8.38. eCollection 2017.

Self-sensing techniques for atomic force microscope (AFM) cantilevers have several advantageous characteristics compared to the optical beam deflection method. The possibility of down scaling, parallelization of cantilever arrays and the absence of optical interference associated imaging artifacts have led...

Does core mobility of lumbar total disc arthroplasty influence sagittal and frontal intervertebral displacement? Radiologic comparison with fixed-core prosthesis.

SAS journal

Delécrin J, Allain J, Beaurain J, Steib JP, Chataigner H, Aubourg L, Huppert J, Ameil M, Nguyen JM.
PMID: 25802632
SAS J. 2009 Sep 01;3(3):91-9. doi: 10.1016/j.esas.2009.09.001. eCollection 2009.

BACKGROUND: An artificial disc prosthesis is thought to restore segmental motion in the lumbar spine. However, it is reported that disc prosthesis can increase the intervertebral translation (VT). The concept of the mobile-core prosthesis is to mimic the kinematic...

Dynamic filtering improves attentional state prediction with fNIRS.

Biomedical optics express

Harrivel AR, Weissman DH, Noll DC, Huppert T, Peltier SJ.
PMID: 27231602
Biomed Opt Express. 2016 Feb 23;7(3):979-1002. doi: 10.1364/BOE.7.000979. eCollection 2016 Mar 01.

Brain activity can predict a person's level of engagement in an attentional task. However, estimates of brain activity are often confounded by measurement artifacts and systemic physiological noise. The optimal method for filtering this noise - thereby increasing such...

The whole truth and nothing but the truth: the need for full reporting of randomised trials.

Perioperative medicine (London, England)

Pearse RM.
PMID: 26203354
Perioper Med (Lond). 2015 Jul 22;4:7. doi: 10.1186/s13741-015-0017-9. eCollection 2015.

The use of cardiac output monitoring to guide fluid and inotropic therapy in surgical patients has remained a controversial topic for more than 40 years. The reasons for this are numerous and complex, but key amongst them is the...

Excited state proton transfer in reverse micelles.

Journal of the American Chemical Society

Cohen B, Huppert D, Solntsev KM, Tsfadia Y, Nachliel E, Gutman M.
PMID: 12071764
J Am Chem Soc. 2002 Jun 26;124(25):7539-47. doi: 10.1021/ja012646c.

The aqueous phase of water/AOT reversed micelles having varying diameters was probed by a single free diffusing proton that was released form a hydrophilic photoacid molecule (2-naphthol-6,8-disulfonate). The fluorescence decay signals were reconstructed through the geminate recombination algorithm, accounting...

Colorful Friedel-Crafts chemistry of meso-tetraarylporphyrins. An unexpected route to porphyrinic spiro dimers.

Organic letters

Jeandon C, Ruppert R, Richeter S, Callot HJ.
PMID: 12713305
Org Lett. 2003 May 01;5(9):1487-9. doi: 10.1021/ol0342554.

Under Friedel-Crafts conditions, meso-tetraarylporphyrins give porphyrin spiro dimers in good yield. This reaction involves acylation, acid-catalyzed cyclization, and dimerization. A stable dimer possessing three additional six-membered rings could be isolated and its structure determined. By modifying the substrate and...

Nonaromatic corroles: regioselectivity of electrophilic substitution.

The Journal of organic chemistry

Ruppert R, Jeandon C, Callot HJ.
PMID: 18095708
J Org Chem. 2008 Jan 18;73(2):694-700. doi: 10.1021/jo702321h. Epub 2007 Dec 21.

Ring contraction of nickel meso-tetraarylporphyrins produced nonaromatic divalent corroles bearing a benzoyloxy function. We investigated their reactivity under electrophilic conditions: formylation, halogenation, nitration. We also found that the benzoate function could be eliminated to afford deoxocorroles, and we tested...
