    International audience; Natural Language Processing has massively evolved during the last years and many up-to-date applications integrate different speech tools in order to create an enhanced user experiences. For obtaining a seamless integration of existing speech recognition systems, there is a trending interest for developing and improving existing speech-to-text algorithms. The aim of this paper is to improve user interaction with the ReaderBench platform, by developing and integrating a speech recognition module designed so that young pupils can dictate their self-explanations to a given text. Afterwards, the ReaderBench framework is used to automatically evaluate the employed reading strategies based on the resulted speech transcriptions. A dataset containing 160 self-explanations from students ranging from 9 to 11 years old was analysed using both original transcripts, and the ones automatically generated by our custom speech recognition system. Multiple methods designed to perform speech recognition are also compared, while a new dedicated model was trained in order to improve the quality of the existing French model for speech recognition from CMUSphinx speech recognition system. Our revised model includes a pronunciation dictionary obtained after training a Long Short-Term Memory (LSTM) Grapheme-to-Phoneme neural network. The accuracy of our system is benchmarked in relation to the automated process of identifying reading strategies implemented in our ReaderBench framework, which is applied on both manual transcriptions and automated speech-to-text inputs. The obtained results argue for the adequacy of our method as the slight decrease in terms of identification accuracy is justifiable in contrast to the effort of manually transcribing each self-explanation.

    AbstractThe house mouse (Mus musculus) represents the extreme of globalization of invasive mammals. However, the timing and basis of its origin and early phases of dispersal remain poorly documented. To track its synanthropisation and subsequent invasive spread during the develoment of complex human societies, we analyzed 829Musspecimens from 43 archaeological contexts in Southwestern Asia and Southeastern Europe, between 40,000 and 3,000 cal. BP, combining geometric morphometrics numerical taxonomy, ancient mitochondrial DNA and direct radiocarbon dating. We found that large late hunter-gatherer sedentary settlements in the Levant, c. 14,500 cal. BP, promoted the commensal behaviour of the house mouse, which probably led the commensal pathway to cat domestication. House mouse invasive spread was then fostered through the emergence of agriculture throughout the Near East 12,000 years ago. Stowaway transport of house mice to Cyprus can be inferred as early as 10,800 years ago. However, the house mouse invasion of Europe did not happen until the development of proto urbanism and exchange networks — 6,500 years ago in Eastern Europe and 4000 years ago in Southern Europe — which in turn may have driven the first human mediated dispersal of cats in Europe.

    We compare a variety of methods for estimating the gas/ice depth offset (Δdepth) at EPICA Dome C (EDC, East Antarctica). (1) Purely based on modelling efforts, Δdepth can be estimated combining a firn densification with an ice flow model. (2) The diffusive column height can be estimated from δ15N and converted to Δdepth using an ice flow model and assumptions about past average firn density and thickness of the convective zone. (3) Ice and gas synchronisation of the EDC ice core to the GRIP, EDML and TALDICE ice cores shifts the ice/gas offset problem into higher accumulation ice cores where it can be more accurately evaluated. (4) Finally, the bipolar seesaw hypothesis allows us to synchronise the ice isotopic record with the gas CH4 record, the later being taken as a proxy of Greenland temperature. The general agreement of method 4 with methods 2 and 3 confirms that the bipolar seesaw antiphase happened during the last 140 kyr. Applying method 4 to the deeper section of the EDC core confirms that the ice flow is complex and can help to improve our reconstruction of the thinning function and thus, of the EDC age scale. We confirm that method 1 overestimates the glacial Δdepth at EDC and we suggest that it is due to an overestimation of the glacial lock-in depth (LID) by the firn densification model. In contrast, we find that method 1 very likely underestimates Δdepth during Termination II, due either to an underestimated thinning function or to an underestimated LID. Finally, method 2 gives estimates within a few metres of methods 3 and 4 during the last deglacial warming, suggesting that the convective zone at Dome C cannot have been very large at this time, if it existed at all.

    Abstract. The Mediterranean region and the Levant have returned some of the clearest evidence of a climatically dry period occurring around 4200 years ago. However, some regional evidence are controversial and contradictory, and issues remain regarding timing, progression and regional articulation of this event. In this paper we review the evidence from selected proxies (sea-surface temperature, precipitation and temperature reconstructed from pollen, δ18O on speleothems, and δ18O on lacustrine carbonate) over the Mediterranean basin to infer possible regional climate patterns during the interval between 4.3 and 3.8 cal ka BP. The values and limitations of these proxies are discussed, and their potential for furnishing information on seasonality is also explored. Despite the chronological uncertainties, which are the main limitations for disentangling details of the climatic conditions, the data suggests that winter over the Mediterranean was drier condition, in addition to already dry summers. However, some exceptions to this prevail, – where wetter condition seems to have persisted – suggesting regional heterogeneity in climate patterns. Temperature data, even if sparse, also suggest a cooling anomaly, even if this is not uniform. The most common paradigm to interpret the precipitation regime in the Mediterranean – a North Atlantic Oscillation-like pattern – is not completely satisfactory to interpret the selected data.

    International audience; On the coast of Northern Dobrogea, south of the Danube delta, the Greek settlement of Orgame was founded in the mid 7th c. BC, probably by Milesian colonists. The ancient city was located on the Cape Dolojman which today overlooks a large lagoon complex. We undertook a chronostratigraphic study to:(i) understand coastal changes around Cape Dolojman since ca. 5000 years BP in connection with the construction of the Danube delta lobes, and (ii) identify potential sediment impacts related to human occupation of the site. Three cores were extracted from the lagoon area. Sedimentological and biological analyses were undertaken to reconstruct the evolution of the coastal palaeoenvironments. The results show a closure of the marine bay around 3500 cal. BP and its transformation into a lagoon environment. The first major environmental change was due to the construction of the lobe St. George I and the formation of the barrier Lupilor. Around 2000 cal. BP, the formation of an intra-lagoonal lobe, the Dunavatz, led to the gradual transformation of the lagoon into a fluvial-dominated system. Paradoxically, lagoon waters today still wash the ancient Greek harbour environment, which has not been totally infilled by alluvial sediments. To understand this paradox, in a context of coastal progradation, we compared and contrasted the geomorphological data with the nearby city of Istros/Histria, which was already landlocked at this time. The location of these two Greek colonies relative to the coastal sediment cell and barriers partly explains their contrasting palaeoenvironmental evolution. Until 2650 cal. BP, the increase in charcoal and organic matter in sedimentary archives is interpreted as an anthropogenic signal for a more extensive use of the vegetation cover following the foundation of the city of Orgame (e.g. for domestic use and funeral rites).

    International audience; In a recent experiment we demonstrated the possibility to suppress the thermal hysteresis of the phase transition in giant magnetocaloric MnAs thin film by interaction with slow highly charged ions (Ne9+ at 90 keV) [1]. This phenomenon has a major impact for possible applications in magnetic refrigeration and thus its reproducibility and robustness are of prime importance. Here we present some new investigations about the origin and the nature of the irradiation-induced defects responsible for the thermal hysteresis suppression. Considering in particular two samples that receive different ion fluences (two order of magnitude of difference), we investigate the reliability of this process. The stability of the irradiation-induced defects with respect to a soft annealing is studied by X-ray diffraction and magnetometry measurements, which provide some new insights on the mechanisms involved.

    International audience; In this paper we present a semi-automated analysis of student reading performance from the perspective of her text reading level and text understanding. Silences (pauses) between uttered words or read sentences as well as silences between verbalizations given by students are the key points in the analysis of their learning activities. Pause is an essential element in the analysis of a text, which also gives good control over interactions during the processes of text reading and explanation of understanding. This study presents the results specific to pauses in the reading and verbalization using Praat, a tool to analyze spoken productions. Correlations between students' fluency, story understanding, and mean pause duration of reading and explanation phases show consistent results across texts for reading. Results about pauses during explaining yielded low correlations, showing that other variables may influence the pausing behaviors during explaining.

    International audience; Natural Language Processing has massively evolved during the last years and many up-to-date applications integrate different speech tools in order to create an enhanced user experiences. For obtaining a seamless integration of existing speech recognition systems, there is a trending interest for developing and improving existing speech-to-text algorithms. The aim of this paper is to improve user interaction with the ReaderBench platform, by developing and integrating a speech recognition module designed so that young pupils can dictate their self-explanations to a given text. Afterwards, the ReaderBench framework is used to automatically evaluate the employed reading strategies based on the resulted speech transcriptions. A dataset containing 160 self-explanations from students ranging from 9 to 11 years old was analysed using both original transcripts, and the ones automatically generated by our custom speech recognition system. Multiple methods designed to perform speech recognition are also compared, while a new dedicated model was trained in order to improve the quality of the existing French model for speech recognition from CMUSphinx speech recognition system. Our revised model includes a pronunciation dictionary obtained after training a Long Short-Term Memory (LSTM) Grapheme-to-Phoneme neural network. The accuracy of our system is benchmarked in relation to the automated process of identifying reading strategies implemented in our ReaderBench framework, which is applied on both manual transcriptions and automated speech-to-text inputs. The obtained results argue for the adequacy of our method as the slight decrease in terms of identification accuracy is justifiable in contrast to the effort of manually transcribing each self-explanation.

    AbstractThe house mouse (Mus musculus) represents the extreme of globalization of invasive mammals. However, the timing and basis of its origin and early phases of dispersal remain poorly documented. To track its synanthropisation and subsequent invasive spread during the develoment of complex human societies, we analyzed 829Musspecimens from 43 archaeological contexts in Southwestern Asia and Southeastern Europe, between 40,000 and 3,000 cal. BP, combining geometric morphometrics numerical taxonomy, ancient mitochondrial DNA and direct radiocarbon dating. We found that large late hunter-gatherer sedentary settlements in the Levant, c. 14,500 cal. BP, promoted the commensal behaviour of the house mouse, which probably led the commensal pathway to cat domestication. House mouse invasive spread was then fostered through the emergence of agriculture throughout the Near East 12,000 years ago. Stowaway transport of house mice to Cyprus can be inferred as early as 10,800 years ago. However, the house mouse invasion of Europe did not happen until the development of proto urbanism and exchange networks — 6,500 years ago in Eastern Europe and 4000 years ago in Southern Europe — which in turn may have driven the first human mediated dispersal of cats in Europe.

    We compare a variety of methods for estimating the gas/ice depth offset (Δdepth) at EPICA Dome C (EDC, East Antarctica). (1) Purely based on modelling efforts, Δdepth can be estimated combining a firn densification with an ice flow model. (2) The diffusive column height can be estimated from δ15N and converted to Δdepth using an ice flow model and assumptions about past average firn density and thickness of the convective zone. (3) Ice and gas synchronisation of the EDC ice core to the GRIP, EDML and TALDICE ice cores shifts the ice/gas offset problem into higher accumulation ice cores where it can be more accurately evaluated. (4) Finally, the bipolar seesaw hypothesis allows us to synchronise the ice isotopic record with the gas CH4 record, the later being taken as a proxy of Greenland temperature. The general agreement of method 4 with methods 2 and 3 confirms that the bipolar seesaw antiphase happened during the last 140 kyr. Applying method 4 to the deeper section of the EDC core confirms that the ice flow is complex and can help to improve our reconstruction of the thinning function and thus, of the EDC age scale. We confirm that method 1 overestimates the glacial Δdepth at EDC and we suggest that it is due to an overestimation of the glacial lock-in depth (LID) by the firn densification model. In contrast, we find that method 1 very likely underestimates Δdepth during Termination II, due either to an underestimated thinning function or to an underestimated LID. Finally, method 2 gives estimates within a few metres of methods 3 and 4 during the last deglacial warming, suggesting that the convective zone at Dome C cannot have been very large at this time, if it existed at all.
