Pillars of Trust: An Experimental Study on Reputation and Its Effects
This paper presents the results of laboratory experiments on the relevance of reputation for trust and cooperation in social interaction. We have extended a repeated investment game by adding new treatments where reputation is taken more explicitly into account than before. We then compared treatments where the investor and the trustee rate each other and treatments where the investor and the trustee were rated by a third party. The results showed that: (i) third party reputation positively affects cooperation by encapsulating trust; (ii) certain differences in the reputation mechanism can generate different cooperation outcomes. These results have interesting implications for the recent sociological debate on the normative pillars of markets
Towards Comprehensive Computational Representations of Arabic Multiword Expressions
A successful computational treatment of multiword expressions (MWEs) in natural languages leads to a robust NLP system which considers the long-standing problem of language ambiguity caused primarily by this complex linguistic phenomenon. The first step in addressing
this challenge is building an extensive reliable MWEs language resource LR with comprehensive computational representations across all linguistic levels. This forms the cornerstone in understanding the heterogeneous linguistic behaviour of MWEs in their various manifestations. This paper presents a detailed framework for computational representations of Arabic MWEs (ArMWEs) across all linguistic levels based on the state-of-the-art lexical mark-up framework (LMF) with the necessary modifications to suit the distinctive properties of Modern Standard Arabic (MSA). This work forms part of a larger project that aims to develop a comprehensive computational lexicon of ArMWEs for NLP and language pedagogy LP (JOMAL project)

The Raman spectrum of florencite‐(REE) [REEAl3(PO4)2(OH)6]: An integrated experimental and computational approach
Single chip dynamic nuclear polarization microsystem
The integration on a single chip of the sensitivity-relevant electronics of
nuclear magnetic resonance (NMR) and electron spin resonance (ESR)
spectrometers is a promising approach to improve the limit of detection,
especially for samples in the nanoliter and subnanoliter range. Here we
demonstrate the co-integration on a single silicon chip of the front-end
electronics of an NMR and an ESR detector. The excitation/detection planar
spiral microcoils of the NMR and ESR detectors are concentric and interrogate
the same sample volume. This combination of sensors allows to perform dynamic
nuclear polarization (DNP) experiments using a single-chip integrated
microsystem having an area of about 2 mm. In particular, we report H
DNP-enhanced NMR experiments on liquid samples having a volume of about 1 nL
performed at 10.7 GHz(ESR)/16 MHz(NMR). NMR enhancements as large as 50 are
achieved on TEMPOL/HO solutions at room temperature. The use of
state-of-the-art submicrometer integrated circuit technologies should allow the
future extension of the single-chip DNP microsystem approach proposed here up
the THz(ESR)/GHz(NMR) region, corresponding the strongest static magnetic
fields currently available. Particularly interesting is the possibility to
create arrays of such sensors for parallel DNP-enhanced NMR spectroscopy of
nanoliter and subnanoliter samples
NMR spectroscopy of single sub-nL ova with inductive ultra-compact single-chip probes
Nuclear magnetic resonance (NMR) spectroscopy enables non-invasive chemical studies of intact
living matter. However, the use of NMR at the volume scale typical of microorganisms is hindered by
sensitivity limitations, and experiments on single intact organisms have so far been limited to entities
having volumes larger than 5 nL. Here we show NMR spectroscopy experiments conducted on single
intact ova of 0.1 and 0.5 nL (i.e. 10 to 50 times smaller than previously achieved), thereby reaching
the relevant volume scale where life development begins for a broad variety of organisms, humans
included. Performing experiments with inductive ultra-compact (1 mm2) single-chip NMR probes,
consisting of a low noise transceiver and a multilayer 150 μm planar microcoil, we demonstrate that the
achieved limit of detection (about 5 pmol of 1H nuclei) is sufficient to detect endogenous compounds.
Our findings suggest that single-chip probes are promising candidates to enable NMR-based study and
selection of microscopic entities at biologically relevant volume scales
