Une veillée médiévale
Authors: Dragovic Mila 
Published: March 2021

L’article est le résultat d’une expérience d’évaluation orale, inspirée par la méthode de simulation globale, d’ordinaire pratiquée dans l’enseignement de langues étrangères, et réitérée à trois reprises en français langue première avec des classes de cinquième au collège. Il est souligné que : l’évaluation orale appelle à une inscription réfléchie dans la progression des apprentissages ; la lecture oralisée est une tâche complexe qui se distingue de la lecture à haute voix ; la réussite de l’évaluation orale repose sur un enseignement/apprentissage conscient de ses différentes composantes, qui incluent non seulement des compétences de mise en voix d’un texte, en l’occurrence un poème épique, mais aussi des connaissances acquises par la lecture analytique de textes mis en contexte et en situation.

L’article s’intéresse à l’emploi des dialogues-en-situation en tant qu’opportunités d’apprentissage lors d’interactions en français en dehors de la classe de langue. A partir d’une démarche d’analyse qualitative des données, notre travail applique les outils de l’analyse conversationnelle (Sacks et al., 1974) afin de mettre en évidence les réalisations des participants : comment ces derniers parviennent à construire un terrain commun, à signaler les orientations du discours à leurs interlocuteurs, à projeter de formes interactionnelles reconnaissables et reconnues (Gajo et Mondada, 2002) et à développer une conscience linguistique en français. En conclusion, nous opérons un rapprochement entre les dialogues-en-situation décrits dans ce travail et la didactique du français.

A New Lifetime Model: Copulas, Properties and Real Lifetime Data Applications
Authors: Shehata Wahid 
Published: March 2021

A new four parameter lifetime model called the Weibullgeneralized Lomax is proposed and studied. The new density function can be "right skewed", "symmetric" and "left skewed" and its corresponding failure rate function can be "monotonically decreasing", " monotonically increasing" and "constant". The skewness of the new distribution can negative and positive. The maximum likelihood method is employed and used for estimating the model parameters. Using the "biases" and "mean squared errors", we performed simulation experiments for assessing the finite sample behavior of the maximum likelihood estimators. The new model deserved to be chosen as the best model among many well-known Lomax extension such as exponentiated Lomax, gamma Lomax, Kumaraswamy Lomax, odd log-logistic Lomax, Macdonald Lomax, beta Lomax, reduced odd log-logistic Lomax, reduced Burr-Hatke Lomax, reduced WG-Lx, special generalized mixture Lomax and the standard Lomax distributions in modeling the "failure times" and the "service times" data sets.

Improved Typelog Alignment for Automated Geosteering Using Multi-Stage Penalized Optimization
Authors: Sun Jin , Maus Stefan 
Published: March 2021

Abstract
Automated geosteering relies on logging-while-drilling data from offset wells to make inferences about the geological formation and help guide directional drilling of the subject well. When data from multiple offset wells are available, it is desirable to consistently combine data typelogs from these wells to better estimate the 3D geological formation around the drilling path. We develop a quantitative typelog alignment method based on a Bayesian approach, where the alignment map between pairs of typelogs are modeled as a random function with a prior distribution. A multi-stage penalized procedure is developed that optimizes this alignment map to minimize a misfit function, while taking the prior knowledge into consideration.
Drill Bit Design Features that Initiate and Reduce High Frequency Torsional Oscillations
Authors: Spencer Reed W. , Bomidi John A. , Huang Xu 
Published: March 2021

AbstractThis paper reports the development of and the results of high frequency torsional oscillation (HFTO) tests performed on full-sized PDC drill bits and single cutters in a drilling laboratory. The research team used a pressurized laboratory drilling rig to test different drill bit designs in new and worn conditions. These tests were performed in different rock types, at different revolution per minute (RPM), weight on bit (WOB) and depth of cut (DOC) values. High frequency drill stem torque (5120 Hz) and in-bit tangential acceleration (1400 Hz) data were recorded, along with all other drilling parameters. Spectrograms of torque data were plotted to identify frequency changes in time. The torque data was filtered to remove the low frequency behavior and focus on the HFTO behavior. The high frequency torque signal correlates well with in-bit tangential accelerations. Root mean square (RMS) values of this filtered torque signal were calculated and plotted vs average WOB, depth of cut, and torque values. Sharp and worn bit geometry, were dull graded on a per cutter basis and were input to a 3D drilling modeling software and correlated with test data in order to determine the DOC at which wear flats or cutting faces engage the rock and cause changes in HFTO behavior. The main results from this research are 1) a lab test and data analysis were developed that can measure a drill bit's propensity to initiate HFTO vibrations in the BHA, 2) HFTO RMS high-pass filtered torque values generally increase with DOC, 3) bits in the new state show more HFTO behavior if cutter design is more aggressive, and 4) wear flat engagement causes high HFTO behavior.

Published: March 2021

Abstract
Background: Perimenopausal women experience a wide variety of systemic symptoms: hot flashes, sweating, psychiatric symptoms and various oral sensory complaints (OSC). OSC in perimenopausal women include xerostomia, taste disturbance and burning mouth. However, the factors associated with these OSC have not been identified. The purpose of this investigation was to elucidate the factors associated with OSC in perimenopausal women．Methods: The study cohort comprised 43 perimenopausal women aged 45–55 years. Data on medical history, medications, menstrual status, menopausal symptoms, xerostomia, taste disturbance and burning mouth were collected. Volumes of unstimulated and stimulated saliva were measured. Tongue coating was evaluated according to a tongue coating index. Univariate analysis was performed to identify factors significantly associated with having xerostomia, taste disturbance, burning mouth and more than two OSC (2OSC). Next, the factors strongly associated with these symptoms were examined by logistic regression analysis.Results: The number of menopausal symptoms was significantly higher, and volume of unstimulated saliva significantly lower in participants with xerostomia, taste disturbance, burning mouth or 2OSC than in those without these characteristics. Agents targeting the central nervous system were more frequently taken by participants with burning mouth and 2OSC than by those without these characteristics. According to logistic regression analysis, the number of menopausal symptoms was an explanatory variable for xerostomia, taste disturbance, burning mouth and 2OSC. Conclusions: Our findings suggested that OSC associated with the number of menopausal symptoms. Management of menopausal symptoms may decrease OSC, leading to improved quality of life of perimenopausal women.

Abstract
Here we investigated the effect of different LED light sources on the essential oil components and antioxidant activity of Melissa officinalis. Two genotypes of lemon balm (Ilam and Isfahan) were subjected to four artificial light treatments including white, red, blue, red + blue LEDs and greenhouse light as natural lighting. The LED lights significantly increased shoot fresh and dry weights and Leaf number in the two genotypes as compared to greenhouse condition. The results showed that the content and composition of essential oil in two genotypes was variable under different light treatments and the total amount of compounds in Ilam genotype was higher than the other genotype. The results of analysis of the essential oil by GC/MS indicated that the highest amount of monoterpenes in the genotypes was related to citronellal under red + blue LED lamps (15.3 and 17.2% in Ilam and Isfahan genotypes, respectively) but blue, white, and greenhouse condition had the most effect on sesquiterpenes content in both genotypes. Furthermore, the observed variation between the two genotypes in the essentials oil composition was related to the relative percentage of the constituents and not to the appearance or lack of a specific component. Red + blue lighting also caused the highest radical scavenging activity % in both genotypes (80.77 and 82.09% for Ilam and Isfahan genotypes, respectively). Based on principal component analyses (PCA), three main groups were identified regarding genotypes and all light treatments. Overall, results indicated that the essentials oil composition of two genotypes of lemon balm was affected both qualitatively and quantitatively by different LED light sources; hence, LED lights might be used to improve monoterpenes, sesquiterpenes and antioxidant activity in the selected genotypes.

Abstract
Background: In the absence of AIDS vaccine，antiretroviral therapy (ART) was the most effective tool to prevent and control the HIV pandemic. But the widespread use of ART has raised concerns about the emergence of HIV transmitted drug resistance (TDR). Acute HIV infection (AHI) was the most appropriate time to detect the spread of TDR. In this meta-analysis, our purpose was to evaluate the level of TDR in ART-naive patients with acute/ primary/ early HIV infection, and describe the critical drug-resistant mutations. Methods: We systematically reviewed 1192 studies published between January 1, 2008 and December 30, 2019 in PubMed, Web of Science, Embase, and the Cochrane Library, and selected 12 studies that meet our inclusion criteria. To evaluate the overall prevalence of TDR, we extracted raw data and analyzed prevalence estimates using Stata SE. Estimates of mixed-effects were calculated by random-effects meta-analysis, and the I²statistics were used to estimate the heterogeneity of all included studies.Results: The Data of this meta-analysis come from 12 observational studies, covering 3558 ART-naive individuals with PHI, AHI or EHI. The overall prevalence of HIV-TDR is 9.8% (95% confidence interval (CI): 7.2%–12.3%, p<0.001). Prevalence of resistance by drug class is highest for the NNRTIs at 5.9% (95% CI: 3.1%–8.6%, p<0.001), followed by NRTIs 3.4% (95% CI: 1.8%–5.0%, p<0.001) and PIs 3.4% (95% CI: 2.7%–4.0%, p<0.001). The prevalence of TDR to INIs is 0.3% (95% CI: -0.1%-0.7%, p<0.001), which is the lowest among all antiretroviral drugs.Conclusion: The overall prevalence of TDR is high among AHI patients who have never received ART. This emphasizes the importance of baseline drug resistance testing for public health surveillance and guiding the choice of ART. In addition, the prevalence of TDR to NNRTIs is the highest, while the TDR to INIs is the lowest. This may guide the selection of clinical antiretroviral drugs.
FACER: An API Usage-based Code-example Recommender for Opportunistic Reuse
Authors: Abid Shamsa , Shamail Shafay , Basit Hamid Abdul , Nadi Sarah 
Published: March 2021

Abstract
To save time, developers often search for code examples that implement their desired software features. Existing code search techniques typically focus on ﬁnding code snippets for a single given query, which means that developers need to perform a separate search for each desired functionality. In this paper, we pro-pose FACER (Feature-driven API usage-based Code Examples Recommender), a technique that avoids repeated searches through opportunistic reuse. Speciﬁcally, given the selected code snippet that matches the initial search query, FACER ﬁnds and suggests related code snippets that represent features that the developer may want to implement next. FACER ﬁrst constructs a code fact repository by parsing the source code of open-source Java projects to obtain methods’ textual information, call graphs, and Application Programming Interface (API) usages. It then detects unique features by clustering methods based on similar API us-ages, where each cluster represents a feature or functionality. Finally, it detects frequently co-occurring features across projects using frequent pattern mining and recommends related methods from the mined patterns. To evaluate FACER, we run it on 120 Java Android apps from GitHub. We ﬁrst manually validate that the detected method clusters represent methods with similar functionality. We then perform an automated evaluation to determine the best parameters (e.g., similarity threshold) for FACER. We recruit 10 professional developers along with 39 experienced students to judge FACER’s recommendation of related methods. Our results show that, on average, FACER’s recommendations are 80% precise. We also survey a total of 20 professional Android and Java developers to understand their code search and reuse experiences, and also to obtain their feedback on the usability and usefulness of FACER. The survey results show that 95% of our surveyed professional developers ﬁnd the idea of related method recommendations useful during code reuse.
Planning considerations of green corridors for the improvement of biodiversity resilience in suburban areas

Published: March 2021

Abstract
The world is experiencing a rapid loss in the biodiversity of pollinator insects. Habitat segmentation caused by infrastructures is one of the contributing factors. To improve the habitat connectivity of pollinator insects, it is proposed in this study to build green corridors for pollinators over linear infrastructures such as highways. In the context of suburban areas of a large city, this study examines differences in air parameters between natural environments and a roadside environment based on monitored and estimated data. Influences of different green corridor designs on floral scent dispersion are also investigated using computational fluid dynamics (CFD) modeling and simulation. It is found that, if flower plants are installed on highway overpasses, the floral scents would be better preserved as compared with those in a natural environment due to the lower concentration of oxidative radicals in the air over highways. The stronger floral scents and their wider dispersion may help attract pollinators. Conversely, highway air contains a variety of volatine organic components (VOCs) that are likely traced to highway operations and pavements. Hence, the overall profile of VOCs in a highway environment differs from that in a natural environment. Results from CFD modeling and simulation suggest that the use of green corridors planted with flowers on the highway overpass can greatly improve the connectivity of floral scents. Hence, with proper engineering design and right combination of plant species, green corridors built on highway overpasses have the potential to facilitate pollinators to cross the road, thereby improving their habitat connectivity and resilience against declining biodiversity.
Take one for the team: On the time efficiency of application-level buffer-aided data relaying in edge cloud communication

Published: March 2021

Abstract
Background: Adding buffers to networks is part of the fundamental advance in data communication. Since edge cloud computing is based on the heterogeneous collaboration network model in a federated environment, it is natural to consider buffer-aided data communication for edge cloud applications. However, the existing studies generally pursue the beneficial features of buffering at a cost of time, not to mention that many investigations are focused on lower-layer data packets rather than application-level communication transactions.Aims: Driven by a counterintuitive argument against the claim that buffers "can introduce additional delay to the communication between the source and destination", this research aims to investigate whether or not (and if yes, to what extent) the application-level buffering mechanism can improve the time efficiency in edge-cloud data transmissions.Method: To collect empirical evidence for the theoretical discussion, we built up a testbed to simulate a remote health monitoring system, and conducted both experimental and modeling investigations into the first-in-first-served (FIFS) and buffer-aided data transmissions at a relay node in the system.Results: An empirical inequality system is established for revealing the time efficiency of buffer-aided edge cloud communication. For example, given the reference of transmitting the 11th data entity in the FIFS manner, the inequality system suggests buffering up to 50 data entities into one transmission transaction on our testbed.Conclusions: Despite the trade-off benefits (e.g., energy efficiency and fault tolerance) of buffering data, our investigation argues that the buffering mechanism can also speed up data transmission under certain circumstances, and thus it would be worth taking data buffering into account when designing and developing edge cloud applications even in the time-critical context.

Abstract
Background : Although a significant proportion of type 2 diabetes mellitus (T2DM) cases arose from normal-weight individuals, studies on indicators that can predict T2DM in normal-weight people are limited. Accordingly, this study aims to investigate the predictive value of obesity indices and triglyceride glucose related parameters (TyG-related parameters) in T2DM among normal-weight Chinese elderly. Methods : A total of 24,215 normal-weight Chinese elderly (age ≥ 60 years) [body mass index--BMI (18.5-23.9 kg/m 2 )] were included. Obesity indices and triglyceride glucose related parameters (TyG-related parameters) included waist circumference (WC), waist-to-height ratio (WHtR), visceral adiposity index (VAI), lipid accumulation product (LAP), and TyG-related parameters (TyG, TyG-BMI, TyG-WC, and TyG-WHtR). Multivariate logistic regression analysis was performed to examine the associations between obesity-and TyG-related indices and T2DM. The areas under the curve (AUC) of the receiver-operating characteristic (ROC) curve analyses were used to evaluate and compare the predictive value of the different indices. Results : The prevalence of T2DM was 14.2% in normal-weight individuals. Among the indices, TyG was significantly associated with T2DM among men and women, respectively (adjusted odds ratio--aOR 19.005; 95% CI 13.235–27.291) and (aOR 25.262; 95% CI 16.957–37.634). Compared with other indices, TyG had the highest AUC value for T2DM in men (AUC: 0.818, 95% CI 0.810–0.825) and women (AUC: 0.824, 95% CI 0.814–0.833). Conclusions : TyG is an effective marker and outperforms than other indices when predicting T2DM in the normal-weight Chinese elderly population.
