Root lexical features and inflectional marking of tense in Proto-Indo-European

2009

This paper examines early inflectional morphology related to the tense-aspect system of Proto-Indo-European. It will be argued that historical linguistics can shed light on the long-standing debate over the emergence of tense-aspect morphology in language acquisition. The dispute over this issue is well-known; it has been pursued mostly by scholars following various general linguistic approaches, from typology to acquisition, but also by historical linguists and Indo-Europeanists, who have long debated about the precedence of aspect or tense from both a synchronic and a diachronic perspective. However, so far Indo-Europeanists have rarely confronted their results in a successful way with re…

Cardiac rehabilitation and 5-year mortality after acute coronary syndromes: The 2005 French FAST-MI study.

2016

IF 2.271; International audience; Background. - Clinical studies have shown a beneficial effect of cardiac rehabilitation (CR) on mortality.Objective. - To study the effect of CR prescription at discharge on 5-year mortality in patients with acute myocardial infarction (AMI).Methods. - Participants, from the 2005 French FAST-MI hospital registry, were 2894 survivors at discharge, divided according to AMI type: ST-segment elevation myocardial infarction (STEMI; n=1523) and non-STEMI (NSTEMI; n=1371). The effect of CR prescription on mortality was analysed using a Cox proportional hazards model.Results. - At discharge, 22.1% of patients had a CR prescription. Patients referred to CR were youn…

Estimate the mean electricity consumption curve by survey and take auxiliary information into account

2012

In this thesis, we are interested in estimating the mean electricity consumption curve. Since the study variable is functional and storage capacities are limited or transmission cost are high survey sampling techniques are interesting alternatives to signal compression techniques. We extend, in this functional framework, estimation methods that take into account available auxiliary information and that can improve the accuracy of the Horvitz-Thompson estimator of the mean trajectory. The first approach uses the auxiliary information at the estimation stage, the mean curve is estimated using model-assisted estimators with functional linear regression models. The second method involves the au…

The Homeric compound Ὑπερίων and the sun in the Indo-European culture

2017

This paper aims at reconstructing the semantic meaning of Homeric Ὑπερίων, the epithet of the sun, whose etymology is still not clear. After presenting the modern interpretations, which describe it as an adjective in the comparative form derived from the adverbial particle ὑπέρ ‘up, above’, the ancient grammarians’ hypothesis on Ὑπερίων as a compound is tested, taking into consideration the textual analysis of those discourse contexts in which the terms for sun are used in archaic Greek and Vedic Sanskrit in comparative perspective. In particular, the co-occurrence with the motion verb go, i.e. εἶμι and i from the same IE root *h1ey-, in the Homeric poems and in the Rigveda respectively, mi…

Effect of Polymer Length on the Adsorption onto Aluminogermanate Imogolite Nanotubes

2021

This study evidences the adsorption of model nonionic polymers onto aluminogermanate imogolite nanotubes, attractive porous nanofillers with potential molecular loading and release applications. We resolve the underlying mechanisms between nanotubes and polyethylene glycols with different molecular weights by means of nanoisothermal titration calorimetry. The analysis of the results provides a direct thermodynamic characterization, allowing us to propose a detailed description of the energetics involved in the formation of polymer/imogolite complexes. The affinity toward the nanotube surface is enthalpy-driven and strongly depends on the polymer chain length, which significantly affects the…

About entangled networks of worm-like micelles: a rejected hypothesis

1996

We report new results from small-angle neutron scattering on d(1 2)-cyclohexane/lecithin/water micellar solutions performed as a function of the water content (w(o)), temperature (T) and dispersed phase volume fraction (phi). The data from dilute samples are interpretable in terms of the existence of giant cylindrical reverse micelles and are well fit with a core-shell model (that provides the micelle structure and dimensions) with values of 28 and 45 Angstrom for the inner core and the outer shell radii, almost independent on temperature and concentration. Such a result could appear consistent with the current idea that worm-like micelles are living polymers. On the contrary, the appearanc…

The occupation of the State Property

2019

Untitled occupation of the State property generates patrimonial, financial and economic damages. This phenomenon therefore prevents the owner and manager of the State property from effectively benefitting from their domain and hinders any economic development of the State property by slowing or stopping further investment into the State property. Untitled occupation is also a phenomenon that goes beyond the interests of the owner and manager of the domain since it is likely to create a competitive disadvantage between regular and illegal occupants.While it is impossible to fight untitled occupation of state property in the long term due to its protean and recurrent nature, the only solution…

Suitability Of Cellular Network Signaling Data For Origin-Destination Matrix Construction: A Case Study Of Lyon Region (France)

2019

TRB 2019, 98th Annual Meeting Transportation Research Board, Washigton, D.C., ETATS-UNIS, 13-/01/2019 - 17/01/2019; Spatiotemporal data, and more specifically origin-destination matrices, are critical inputs to mobility studies for transportation planning and urban management purposes. In this paper, we propose a methodology to infer origin-destination (O-D) matrices based on passively-collected cellular signaling data of millions of anonymized mobile phone users in the Rhône-Alpes region, France. This dataset, which consists of records time-stamped with users' unique identifier and tower locations, is used to first analyze the cell phone activity degree indicators of each user in orde…

Decentralized Lightweight Group Key Management for Dynamic Access Control in IoT Environments

2020

Rapid growth of Internet of Things (IoT) devices dealing with sensitive data has led to the emergence of new access control technologies in order to maintain this data safe from unauthorized use. In particular, a dynamic IoT environment, characterized by a high signaling overhead caused by subscribers' mobility, presents a significant concern to ensure secure data distribution to legitimate subscribers. Hence, for such dynamic environments, group key management (GKM) represents the fundamental mechanism for managing the dissemination of keys for access control and secure data distribution. However, existing access control schemes based on GKM and dedicated to IoT are mainly based on ce…
