A popular way to increase the number of online reviews is to use product testing programs, which offer participants free products in exchange for writing reviews. Firms that employ this practice generally hope to increase review quality and secure higher product rating scores. However, a qualitative study, experimental study, and multilevel analysis of a field study dataset of more than 200,000 online reviews by product testers combine to reveal that product testing programs do not necessarily generate higher quality reviews, nor better product ratings. Only in certain circumstances (e.g., higher priced products) does offering a product testing program generate these benefits for the firm. Therefore, companies should consider carefully if and when they want to offer product testing programs.</jats:p>}},

  abstract     = {{<jats:p>When joining lightweight parts of various materials, clinching is a cost efficient solution. In a production line, the quality of a clinch point is primarily controlled by measurement of dimensions, which are accessible from outside. However, methods such as visual testing and measuring the bottom thickness as well as the outer diameter are not able to deliver any information about the most significant geometrical characteristic of the clinch point, neck thickness and undercut. Furthermore, ex-situ destructive methods such as microsectioning cannot detect elastic deformations and cracks that close after unloading. In order to exceed the current limits, a new non-destructive in-situ testing method for the clinching process is necessary. This work proposes a concept to characterize clinch points in-situ by combining two complementary non-destructive methods, namely, computed tomography (CT) and ultrasonic testing. Firstly, clinch points with different geometrical characteristics are analysed experimentally using ex-situ CT to get a highly spatially resolved 3D-image of the object. In this context, highly X-ray attenuating materials enhancing the visibility of the sheet-sheet interface are investigated. Secondly, the test specimens are modelled using finite element method (FEM) and a transient dynamic analysis (TDA) is conducted to study the effect of the geometrical differences on the deformation energy and to qualify the TDA as a fast in-situ non-destructive method for characterizing clinch points at high temporal resolution.</jats:p>}},

  abstract     = {{The efficiency of dynamic nuclear polarization (DNP) enhanced 19F MAS NMR spectroscopy without 19F-containing solvents and matrices, which transport polarization via 19F–19F spin diffusion, is demonstrated. By preventing solvent and matrix signals respectively masking the corresponding resonances, this enables the detection of fluorinated target molecules in nanomolar amounts. As model compound, 1,3,5-tris(2-fluoro-2-methylpropionylamino)benzene (F-BTA) is investigated in a frozen 1,1,2,2-tetrachloroethane (TCE) solution and incorporated into a matrix of isotactic polypropylene (i-PP). While the polarizing agent is homogeneously dissolved within the frozen solution, for the i-PP/F-BTA blend, it is distributed via the incipient wetness impregnation (IWI) technique. For the frozen solutions with an F-BTA concentration of 187.5 mM an εon/off of 260 was obtained. For F-BTA concentrations of 10 and 2.5 mM the sensitivity trend suggests even higher DNP gains. The substantial enhancements could be achieved by direct polarization transfer over distances up to at least 20 Å, derived from a simple geometric model assuming a homogeneous solution, engaging a large part of the sample volume. Cross-polarization (CP) to 13C nuclei allowed selection of the NMR spectroscopic resonances of the minority species in the i-PP/F-BTA blend suppressing the otherwise dominating resonances of the IWI solvent and the polymer matrix. The possibility of exciting 19F via DNP directly and of transferring the polarization to other heteronuclei within close proximity enables spatial spectral editing to clear up spectra otherwise crowded by matrix and solvent signals. We thus expect direct polarization transfer techniques for DNP enhanced NMR spectroscopy to become more important in the future.}},

In addition to ultra-broadband signal processing, it allows leveraging ultra-low jitter mode-locked lasers and thus increasing the aperture jitter limited effective number of bits at high analog signal frequencies. In this paper, we review our recent progress towards optically enabled time- and frequency-interleaved analog-to-digital converters, as well as their monolithic integration in electronic-photonic integrated circuits. For signal frequencies up to 65 GHz, an optoelectronic track-and-hold amplifier based on the source-emitter-follower architecture is shown as a power efficient approach in optically enabled BiCMOS technology. At higher signal frequencies, integrated photonic filters enable signal slicing in the frequency domain and further scaling of the conversion bandwidth, with the reconstruction of a 140 GHz optical signal being shown. We further show how such optically enabled data converter architectures can be applied to a nonlinear Fourier transform based integrated transceiver in particular and discuss their applicability to broadband optical links in general.}},

After a brief introduction to the advanced QCMs, the governing equation (the small-load approximation) is derived. Planar films and adsorbates are modeled based on the acoustic multilayer formalism. In liquid environments, viscoelastic spectroscopy and high-frequency rheology are possible, even on layers with a thickness in the monolayer range. For particulate samples, the contact stiffness can be derived. Because the stress at the contact is large, the force is not always proportional to the displacement. Nonlinear effects are observed, leading to a dependence of the resonance frequency and the resonance bandwidth on the amplitude of oscillation. Partial slip, in particular, can be studied in detail. Advanced topics include structured samples and the extension of the small-load approximation to its tensorial version.</jats:p>}},

In the voltage range of underpotential deposition (UPD), the apparent mass transfer rate shows peaks and shoulders.

  abstract     = {{Textsorten sind ein Begriff der Alltagssprache: Was darunter zu verstehen ist, ist
Sprecher*innen grob geläufig. Geht es allerdings darum, das Wesen von Textsorten und die
Kriterien ihrer Differenzierung zu beschreiben, bleiben auch nach langjähriger
fachwissenschaftlicher Diskussion innerhalb der Linguistik noch immer viele Fragen offen.
Auseinandersetzungen mit dem Gegenstand erfolgten zunächst anhand sehr überschaubarer
Mengen von Textbeispielen und nur selten im Kontrast verschiedener Textsorten. Mit dem
Vorhandensein großer Korpora jedoch ist es nun möglich, viele Vertreter einer Textsorte mit
automatisierten Verfahren und im Vergleich mit großen Korpora anderer Textsorten auf ihre
konstitutiven Merkmale hin zu untersuchen. Zudem stehen mittlerweile zahlreiche Tools und
Werkzeuge zur Verfügung, die die automatische Sprachverarbeitung ermöglichen bzw. die
manuelle Erschließung des Materials mittels Annotation unterstützen. Trotzdem dürfen die
daraus sich ergebenden methodischen Möglichkeiten in ihrer Leistungsfähigkeit auch nicht
überschätzt werden. Quantitatives muss an qualitatives, automatisches an manuelles Arbeiten
rückgekoppelt werden und vice versa, um belastbare Ergebnisse zu erzielen – und es bleibt das
Spannungsfeld zwischen der kritischen Masse und den Grenzen der Fehlertoleranz.
Im Projekt t.evo (DFG, 2019–2022) wird genau diese Synthese angestrebt. Ziel ist, anhand von
Korpora erbaulicher Textsorten des 17. und 18. Jhs. sowie der Pressekommunikation des 19.
und 20. Jhs. (die jeweils als Massenmedium ihrer Zeit gelten können) möglichst
allgemeingültige Kriterien zur Textsortendifferenzierung herauszuarbeiten. Hierzu wurden in
Rückgriff auf den fachwissenschaftlichen Diskurs verschiedene Dimensionen festgelegt, in
denen die musterhaften Erscheinungen verschiedener Textsorten sichtbar und somit
analysierbar gemacht werden sollen. Dabei bedienen wir uns sowohl automatisierter als auch
rein manueller Zugänge zum Korpusmaterial und kombinieren quantitative mit qualitativen
Auswertungsweisen.
Unser Vortrag wird in diese Arbeiten einführen und dabei nicht nur die einzelnen
Arbeitsschritte näher skizzieren, sondern auch Fallstricke der einzelnen Methoden und
schließlich deren Verzahnung zugunsten einer zusammenhängenden Textsortenbeschreibung
eingehen.}},
