Communicating through ancillary gestures: Exploring effects on coperformers and audiences
2020
Musicians make elaborate movements while performing, often using gestures that might seem extraneous. To explore these movements, we motion-captured and audio-recorded different pairings of clarinetists and pianists performing Brahms’ Clarinet Sonata No. 1 with two manipulations: (a) allowing the performers full vs. no visual feedback, and (b) allowing the performers full vs. partial auditory feedback (i.e., the clarinetist could not hear the pianist). We found that observer ratings of audio–visual point-light renditions discriminated between manipulations and refined this insight through subsequent audio-alone and visual-alone experiments, providing an understanding of each modality’s cont…
Women Scientists Who Made Nuclear Astrophysics
2019
Female role models reduce the impact on women of stereotype threat, i.e. of being at risk of conforming to a negative stereotype about one’s social, gender, or racial group (Fine in Delusion of Gender. W.W. Norton & Co. NY, p. 36, 2010 [1]; Steele and Aronson in J Pers Soc Psychol 69:797–811, 1995 [2]). This can lead women scientists to underperform or to leave their scientific career because of negative stereotypes such as, not being as talented or as interested in science as men. Sadly, history rarely provides role models for women scientists; instead, it often renders these women invisible (CafeBabel Homepage [3]). In response to this situation, we present a selection of twelve outst…

Preparation of Nd:YAG Nanopowder in a Confined Environment
2007
Nanopowder of yttrium aluminum garnet (YAG, Y3Al5O12) doped with neodymium ions (Nd:YAG) was prepared in the water/cetyltrimethylammonium bromide/1-butanol/n-heptane system. Aluminum, yttrium, and neodymium nitrates were used as starting materials, and ammonia was used as a precipitating agent. Coprecipitate hydroxide precursors where thermally treated at 900 degrees C to achieve the garnet phase. The starting system with and without reactants was characterized by means of the small-angle neutron scattering technique. The system, without reactants, is constituted by a bicontinuous structure laying near the borderline with the lamellar phase region. The introduction of nitrates stabilizes th…
Le Clos de Vougeot (Côte-d’Or) : nouvelles observations sur les matériaux de construction et la chronologie du bâti médiéval
2009
Mithilfe sehr unterschiedlicherMethoden hat es sich diese Arbeit vor allem zur Aufgabe gemacht, bestimmte Phasen der Baugeschichte des Clos de Vougeot zu verstehen, um die Organisation und die Entwicklungen eines Zisterzienserhofsin Hinsicht auf diesozialen und historischen Wandlungen besser zu verstehen. Diese Studie bot ebenfalls Gelegenheit, die geologischen Eigenschaften der im Clos de Vougeot eingebrachten Baumaterialien genauestens zu untersuchen und neue Erkenntnisse zum Bau dieser Gebäude zu gewinnen und zu präzisieren.
Preliminary approach towards construction of peptide libraries as potential tools for diagnosis of malignant thyroid tumors
2006
Nowotwory złośliwe tarczycy należą do najczęstszych nowotworów złośliwych układu endokrynnego. Poprawa wyników leczenia wiąże się z postępem wczesnej diagnostyki raka. Celem niniejszych badań jest poszukiwanie wskaźników nowotworowych za pomocą bibliotek peptydowych umieszczonych na podłożu z bibuły. Materiał i metody: Analizie poddano tkanki pobrane od 6 pacjentów: 4 z rakiem brodawkowatym tarczycy, 1 z nowotworem pęcherzykowym oraz 1 pacjenta z rakiem oksyfilnym. Badania wykonywano z wykorzystaniem bibliotek peptydowych lipofilowych, porównując tkankę zdrową i chorą oraz oceniając zmianę zabarwienia w poszczególnych bibliotekach. Wyniki: Wstępne wyniki wskazują, że biblioteki peptydowe mo…

GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral
2017
On August 17, 2017 at 12-41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was detected with a combined signal-to-noise ratio of 32.4 and a false-alarm-rate estimate of less than one per 8.0×104 years. We infer the component masses of the binary to be between 0.86 and 2.26 M, in agreement with masses of known neutron stars. Restricting the component spins to the range inferred in binary neutron stars, we find the component masses to be in the range 1.17-1.60 M, with the total mass of the system 2.74-0.01+0.04M. The source was localized within a sky region of 28 deg2 (90% probabili…
Timing an Accreting Millisecond Pulsar: Measuring the Accretion Torque in IGR J00291+5934
2006
We performed a timing analysis of the fastest accreting millisecond pulsar IGR J00291+5934 using RXTE data taken during the outburst of December 2004. We corrected the arrival times of all the events for the orbital (Doppler) effects and performed a timing analysis of the resulting phase delays. In this way we have the possibility to study, for the first time in this class of sources, the spin-up of a millisecond pulsar as a consequence of accretion torques during the X-ray outburst. The accretion torque gives us for the first time an independent estimate of the mass accretion rate onto the neutron star, which can be compared with the observed X-ray luminosity. We also report a revised valu…
Gaia-ESO Survey: H{alpha} emission stars catalogue
2015
We discuss the properties of H{alpha} emission stars across the sample of 22035 spectra from the Gaia-ESO Survey internal data release, observed with the GIRAFFE instrument and largely belonging to stars in young open clusters. Automated fits using two independent Gaussian profiles and a third component accounting for the nebular emission allow us to discern distinct morphological types of H{alpha} line profiles with the introduction of a simplified classification scheme. Altogether we find 3765 stars with intrinsic emission and sort their spectra into eight distinct morphological categories: single component emission, emission blend, sharp emission peaks, double emission, P-Cygni, inverted…
