Contextual information. such as color and spatial location, has been found to be better remembered for emotional than for neutral items. The current study examined whether the influence of emotion extends to memory for another fundamental feature of episodic memory: temporal information. Results from a list-discrimination paradigm showed that (a) item memory was enhanced for both negative and positive pictures compared with neutral ones and was better for negative than for positive pictures and (b) temporal information was better remembered for negative than for positive and neutral pictures, whereas positive and neutral pictures did not differ from each other. These findings are discussed in relation to the processes involved in memory for temporal information. [less ▲]

Although the link between emotion and memory has been demonstrated for long, only one study has examined the impact of emotion on inadvertent plagiarism (cryptomnesia) up to now (Gingerich & Dodson, 2012). The Gingerich and Dodson‘s experiment examined the impact of mood on unintentional plagiarism. The present study examined the effect of emotional content of items on the occurrence of unintentional plagiarism using the Brown and Murphy paradigm (1989). In a first stage, same-sex dyads (96 participants, 48 men, mean age=21.5 years) were asked to generate alternately words corresponding to an emotional category. Three categories were proposed to our participants: positive, neutral and negative. Participants returned after a one week-delay and were instructed (1) to recall the items generated by themselves one week earlier (RO task), (2) to generate four new items for each category (GN task), and (3) to assign a confidence rating. In the RO task, almost 17% of responses were plagiarisms and the percentage almost reached 9% in the GN task. In the RO task, plagiarism was significantly higher for positive than neutral items. In addition, positive and negative items were better recalled than neutral one. These results demonstrate an impact of the emotional content on inadvertent plagiarism. [less ▲]

BACKGROUND: The worldwide epidemiology of causative bacteriae in early-onset infection has been remarkably stable along the last decades.Widespread use of broad-spectrum ABs for early-onset infection in neonates (N) can select multi-resistant bacteriae. OBJECTIVE: We postulated that switching from Ampicillin (A) to Penicillin G (PG) for suspected early-onset infection in our three levels neonatal units, wathever the gestational age, could modify the selective pressure among Enterobacteriacae (EB) and decrease emergence of resistant inducible bacteriae. DESIGN/METHODS: This is a prospective bacteriological survey of 22 months comparing three successive time-periods (P1,2,3) reflecting a progressive switching from Ampicillin-Amikacin (A-Ak) to Penicillin G-Amikacin (PG-Ak). It accounts for respectively A-Ak and PG-Ak (%) : P1 : (66 and 34); P2 : (48 and 52); P3 : (12 and 88). Systematic bacterial screening included blood culture and multiple swabs on admission. Multiple swabs and faeces culture were repeated once a week. Additional cultures were taken when clinically indicated. Antibiograms were done with the Viteck2 System (Biomerieux). Data were collected on the Bacteriological logicial Infopartner R (Nancy). RESULTS: Antenatal AB policy was not modified along the survey. We included 334, 340 and 306 N for P1, P2 and P3, respectively with the same proportion of very preterms. The neonatal morbidity was similar between the three Ps. In respect to the bacteriological screening, no major differences in the proportion of bacterial groups were observed. However, the proportion of inducible EB significantly decreased between the P1 and the P3 (39.7% vs 21.7%, p [less ▲]

Recent research has shown that there are individual differences in how preexisting (internal) schemata (versus cues from the outside world) affect encoding processes, which can be reliably assessed with the internal and external Encoding Style Questionnaire (ESQ, Lewicki, 2005). Since reliance on preexisting schemata at encoding has been found to increase the production of false memories in the DRM paradigm (Roediger & McDermott, 1995), while item-specific encoding has been shown to reduce it (see Gallo, 2006), it was examined whether individual differences in encoding style affects the production of such false memories. To this purpose, normal participants were asked to complete a French version of the ESQ questionnaire (Billieux et al., 2009) and were presented with a modified DRM procedure (Brédart, 2000) assessing false recall. The results showed a positive correlation between ESQ scores and false recall showing that internal encoders were more susceptible to false memories than external encoders. [less ▲]

Polybutadiene samples of different molecular weight have been synthesized by anionic polymerization as initiated by sec-butyllithium with low polydispersity and a major content of 1,2-vinyl units. They have been analyzed by time-of-flight secondary ion mass spectrometry (ToF-SIMS) in order to investigate the sensitivity of this method toward the sec-butyl end group and toward the molecular weight. The SIMS spectra show the characteristic fragment of the end group, C4H9+ at m/z = 57, whose the peak intensity is strongly dependent on the polymer molecular weight, as is the case for almost all the fragment intensities. A model consistent with the peak intensity variations is used to give some new insights into the fragmentation mechanism at the end groups and within the main chain. Moreover, the analysis of the end group fragment allows Mn to be readily determined up to Mn = 4 × 104 from, for example, the Y(53)/Y(57) intensity ratio where Y(53) is the intensity of the deprotonated repeat unit ([M − H]+). Other Mn calibration methods have also been used and are discussed in terms of their accuracy and physical meaning. [less ▲]

This article aims at extending the node to surface formulation for contact problems with an area regularization as proposed by [1]. For that purpose, two methods are proposed to compute the equivalent contact area attributed to each slave node. The first method, which is based on a geometrical approach through force equivalence, is an original extension of the one proposed in [1] for two-dimensional contact problems, i.e. plane stress and plane strain state, to the axisymmetric modelling context. The second method relies on an energy consistent way obtained through the virtual work principle and the same expression for the equivalent contact area as the one originally cited in [2] is then recovered. First, the node to surface strategy with area regularization is introduced and the aforementioned methods for the equivalent contact area are presented in detail and compared. Afterwards a consistent linearization technique is applied to achieve a quadratic convergence rate in the Newton Raphson iterative procedure used to solve the non-linear equilibrium equations of the underlying finite element model. Finally, two axisymmetric numerical examples are provided in order to compare the aforementioned equivalent contact area evaluations and to demonstrate the performance and the robustness of the consistent approach especially in the neighbourhood the revolution axis.

Calcitonin is now a well-accepted therapy for inhibition of bone loss, both in the first years of menopause and in established osteoporosis. However, its exact role in the pathogenesis of that disease as well as the interactions between calcitonin production and estrogen metabolism remain unsolved. In order to clarify the influence of estrogen replacement therapy (ERT) on calcitonin secretory capacity, we measured whole plasma immunoreactive calcitonin basal levels, metabolic clearance rates and production rates in a group of postmenopausal women, before and after a daily intake for 28 days of 0.625 mg/day of conjugated equine estrogens, and again 4 weeks after the withdrawal of that estrogen replacement therapy. No significant changes appeared in immunoreactive calcitonin or immunoreactive calcitonin metabolic clearance rate but the production rate significantly increased over the 28 days (mean +/- SEM, from 21.3 +/- 5.1 pg/ml to 25.2 +/- 5.9 pg/ml, p less than 0.05), and then decreased 4 weeks after therapy was withdrawn to the initial level (17.9 +/- 3.6 pg/ml). We concluded that estrogen replacement therapy significantly increases calcitonin secretory capacity. This confirms the interactions between calcitonin production and estrogen metabolism, and may provide an explanation concerning the mode of action of estrogen replacement therapy in prevention of postmenopausal bone loss.

In the design of nuclear waste disposals, an important topic concerns the development of an excavated damage zone, where permeability increases. A correct numerical prediction of the coupled processes occurring during excavation is therefore needed. In this paper, a nonclassical hydraulic boundary condition is described. It mixes two modes of water exchanges in partial saturation: seepage and evaporation flows. Seepage flow avoids unphysical water inflow into the rock mass, which might be obtained with usual boundary condition in dilatant geomaterial. Evaporation flows enable the thermodynamical equilibrium between air relative humidity in the cavity and in the rock mass. The numerical modeling of a cavity excavation in dilatant geomaterial is carried out. The results show the influence of the hydraulic boundary condition on the convergence of the cavity. Depending on the value of the transfer coefficient, the proposed numerical model can recover the results obtained with an imposed atmospheric pressure or suction at the cavity wall. The determination of the mass transfer coefficient is thus needed and can be achieved through drying experiments or can be estimated thanks to in situ measurements. [less ▲]

The objective of this investigation was to study the effects of sex steroids on levels of haemoglobin (Hb) and haematocrit (Hct) and to analyse whether these effects can be related to levels of the soluble transferrin receptor (sTfR), a marker of erythropoietic activity. Nineteen male-to-female transsexuals were randomly assigned to either oral ethinyl oestradiol (EE) (n=12) or transdermal 17beta-oestradiol (E2) (n=7); both treatments included the anti-androgen cyproterone acetate (CA). Six male-to-female transsexuals were treated with CA only. Fifteen female-to-male transsexuals were treated with i.m. testosterone esters. The Hct, and levels of Hb, IGF-I, GH and sTfR were measured before and after 4 months of hormone administration. Androgen administration significantly increased the sTfR concentration by 31.5% (P=0.008) and increased levels of Hct, Hb and IGF-I. Both regimens of CA with oral EE and transdermal E2 reduced plasma testosterone similarly to castrate values and decreased Hb and Hct. The CA+oral EE combination induced a decrease in sTfR of 19.0% (P=0.002) which was not the case with CA+transdermal E2 (P=0.27). This cannot be explained by the profound decline in plasma testosterone which was similar with both regimens, but this difference could be related to the different effects of the two regimens on plasma IGF-I. This assumption is supported by the positive correlation that was found to exist between plasma sTfR and IGF-I after the interventions (P<0.05). [less ▲]

The characterization of Earth-like extrasolar planets in the mid-infrared is a significant observational challenge that could be tackled by future space-based interferometers. A large effort has been carried out the past two decades to define a design that provides the necessary scientific performance while minimizing cost and technical risks. These efforts have resulted in a consensus on a single mission architecture consisting of a non-coplanar X-array (the so-called Emma configuration), using four collector spacecraft and a single beam combiner spacecraft. The ability to study distant planets with an X-array interferometer will however depend on exozodiacal dust clouds, the counterparts of the solar zodiacal disk. In this paper, we briefly discuss the impact of exozodiacal clouds on the performance of an Emma X-array interferometer dedicated to Earth-like planet characterization. [less ▲]

This paper deals with the examination of the steel grade X210CrW12 and its suitability for Thixoforming. In the semi-solid state, the microstructure of this steel consists of a homogeneous distribution of globular particles surrounded by liquid. Additionally, carbides are stabile up to fraction liquid contents of approximately 40%. After quenching, this steel reveals a globular austenitic microstructure with eutectic (former liquid phase) at the grain boundaries. Compression tests permit to determine the influence of different process parameters on the properties and the material behaviour in the semi-solid state. Their influence on the microstructure was investigated but not yet highlighted. Further investigations on this steel allow a fine-tuning to establish optimal process windows of the different thixoforming- and rheoforming-routes. [less ▲]
