Abstract
Cu3Sb is a known copper-rich phase in the Cu–Sb binary phase diagram. It is reported to be dimorphic, with a low-temperature form adopting the orthorhombic Cu3Ti structure type (space group Pmmn, No. 59). The high-temperature form crystallizes in the cubic space group

(No. 225), and is isostructural with BiF3. Neither polymorph has been carefully characterized to date, with both structures being assigned to the respective structure type, but never refined. With this study, we provide structural evidence, based on single-crystal and powder X-ray diffraction data that the low-temperature orthorhombic phase exists with a significant amount of defects on one of the Cu-sites. As a result, its composition is not Cu3Sb, but rather Cu3–δ
Sb (δ = 0.13(1)). The cubic form could not be accessed as a part of this study, but another Cu-rich phase, Cu3Sb≈0.8In≈0.2, was also identified. It adopts the hexagonal Ni3Sn structure type (space group P63/mmc, No. 194) and represents an In-substituted variant of a hitherto unknown structural modification of Cu3Sb. Whether the latter can exist as a binary phase, or what is the minimum amount of In inclusions needed to stabilize it remains to be determined. Measurements of the thermopower of Cu3–δ
Sb (δ = 0.13(1)) were conducted in the range of 300–600 K and demonstrated a maximum value of ca. 50 μV/K at 600 K, indicative of a p-type transport mechanism. Electrical resistivity measurements for the same sample confirmed that it exhibits metallic-like behavior, with a room temperature value of 0.43 mΩ cm. Electronic structure calculations show the absence of a band gap. Thermal analysis was utilized to ascertain the congruent melting of both phases.

Sekiguchi, Y, Curtis, RM, Huggins, RA, Benjamin, CL, Walker, AJ, Arent, SM, Adams, WM, Anderson, T, and Casa, DJ. The relationships between perceived wellness of, sleep of, and acute: chronic training load on National Collegiate Athletics Association division I male soccer players. J Strength Cond Res 35(5): 1326–1330, 2021—The purpose of this study was to investigate relationships between perceived wellness, sleep, and acute: chronic workload ratio (ACWR) throughout a collegiate men's soccer season. Sixty male collegiate soccer players (mean[M] ± SD; age, 21±2 year; body mass, 77.6 ± 6.5 kg; height, 180.1 ± 6.4 cm; body fat%, 9.9 ± 3.9% ; and V̇o
2max, 53.1 ± 5.0 ml·kg−1·min−1) participated in this study. During each session, players used a heart rate and global positioning satellite–enabled chest strap to measure training impulse and ACWR. The ACWR values were trichotomized at the individual level giving an equal number of observations within each ACWR category of low, moderate, and high ACWR (M ± SD; low, 0.658 ± 0.23; moderate, 0.92 ± 0.15; and high, 1.17 ± 0.16). Stress, fatigue, and soreness levels were collected using 1–10 Likert scales and sleep duration, and sleep quality were measured by the Karolinska Sleep Diary. Stress, fatigue, soreness levels, and sleep quality were transformed to corresponding z-scores at the individual level. Fatigue levels were significantly higher when ACWR was high compared with low (mean difference [95% confidence intervals], effect size, p-value; 0.31 [0.21, 0.42], 0.29, p < 0.001) and moderate (0.14 [0.03, 0.24], 0.13, p = 0.01). Fatigue levels were also significantly higher when the ACWR was moderate compared with low (0.18 [0.07, 0.28], 0.16, p = 0.001). Soreness levels were significantly higher when the ACWR was high compared with low (0.25 [0.14, 0.36], 0.23, p < 0.001). Stress levels were significantly greater when the ACWR was high compared with low (0.19, [0.08, 0.29], 0.18, p < 0.001) and compared with moderate (0.15, [0.05, 0.25], 0.14, p = 0.004). There were no differences in sleep duration or sleep quality in different ACWR. The ACWR may be a useful tool to achieve an appropriate balance between training and recovery to manage daily fatigue and soreness levels in athletes.

Published: March 2021

Cet article présente l’utilisation, en classe de langue, de corpus audiovisuels documentant les rites funéraires malgaches. Dans un contexte d’éloignement, ces corpus permettent effectivement de réduire la distance géographique, en donnant à voir aux apprenants, des réalités qu’ils n’ont pas vécues. Mais ces corpus permettent aussi de réduire la « distance culturelle » : bien que les règles attachées au comportement prescrit durant les funérailles, divergent entre la culture source et la culture cible, elles mettent en évidence l’universalité.
L’écosystème des mots en danger?
Authors: HOSOKAWA Naoko 
Published: March 2021

La communication proposée vise à examiner la part de mythe et de réalité dans le rôle des mots empruntés aux langues étrangères, en explorant une analogie avec l’étude biologique sur de prétendues « espèces invasives» dans un environnement naturel. L’usage des mots empruntés aux langues étrangères, à l’anglais en particulier, est aujourd’hui au centre d’une controverse car certains disent qu’il est le signe d’une invasion culturelle. Dans le domaine environnemental, les espèces étrangères nouvellement arrivées sont généralement qualifiées d’«invasives» et de «destructrices» pour l’écosystème «natif». En prenant un cas d’étude dans le Japon contemporain, notre communication examine les arguments sur le rôle des espèces étrangères afin d’évaluer à quels degrés ils sont applicables dans le discours linguistique sur l’emprunt lexical et suggère que la critique contre «les mots étrangers invasifs» est en grande partie le produit d’une construction discursive enracinée dans la peur de l’«inconnu».
Annular Pressure Management - Benefits from Using Along-String Measurements in Real Time While Tripping

Published: March 2021

Abstract
The objective of this paper is to discuss and outline how downhole pressure data conveyed through the wired drill pipe (WDP) telemetry system was used by the Snorre Expansion Project (SEP) team to drill pressure restrictive reservoirs safely and efficiently.
An original equipment manufacturers (OEM) WDP system was deployed on a ram rig for SEP late summer 2019 for the 24 well campaign. Drilling at six separate templates scattered between Snorre A and B, formation, well path and pressure regimes, differ significantly throughout the project. SEP divided its year into two phases: drilling during the Autumn and Winter seasons, and completion during Spring and Summer. To monitor and act on the changes in pressure, real-time along the string sensors were utilized through the WDP system. In conjunction with the newly developed prototype data while tripping (DWT) tool, constant 0.5 Hz pressure data was transferred real-time from downhole to the decision makers on the rig and onshore, both while drilling and tripping.
Allowing for continuous surveillance of the downhole condition proved crucial during the first reservoir section of the project that was drilled during a heavy Winter storm in January 2020. As well as gauging the effectiveness of the hole cleaning, the downhole impact of rig heave was also measured by the pressure sensors. The sensors showed that 1.5 to 2.0 m rig heave would result in up to ±20 bar fluctuation of the lowermost sensor, risking downhole pressure to go below the pore pressure of the formation. Acting on the real-time information, the rig halted drilling and pulled the string to the shoe, waiting out the weather. Swab pressures were measured while tripping and used to adjust the string speed, avoiding proximity to the pore pressure.
The drilling program was subsequently changed, postponing most challenging reservoir sections to the spring, thereby avoiding a similar situation or worse.

Published: March 2021

Abstract
This paper describes the development of an improved polycrystalline diamond cutter (PDC) drilling performance simulation in 3D which includes worn cutters. A polygonal mesh model is used to improve the geometric data needed for the drilling performance model calculations. Methods for active face identification have been developed to consistently identify a variety of polygonal face types. The simple wear flat definition used for data input is shown to adequately capture the geometry compared to field worn bit scans and provide valuable insights with active face identification. Drilling performance calculation and results from the calibration to laboratory drilling data and validation to both laboratory and field data are shown. Additionally, including a velocity parameter in the drilling performance model reduced model error.
A Medical-Inspired Framework to Classify Downhole Shocks Waveforms While Drilling
Authors: Matheus Justo , Ignova Maja , Amaya Darwin 
Published: March 2021

Abstract
This paper presents a medical approach to classify shock waveforms acquired at 31,250 hertz downhole. The shock signals are treated as drilling electrocardiogram (D-ECG). The D-ECGs are processed using clustering algorithms and merged with drilling incidents to identify an arrhythmic signature pattern that can lead to catastrophic failures.
In medicine, the analysis of heartbeat cycles in an electrocardiogram signal is very important for monitoring heart patients. In the drilling industry, downhole shocks are present most of the time. They are present so often that the authors introduce the concept of drilling electrocardiogram (D-ECG) based on shock waveforms acquired at high frequency. The shock module was implemented in hardware using a field programmable gate array (FPGA) and run inside the control unit of an RSS to complement the navigation systems composed. The shock acquisition and processing are performed at 31,250 Hz, providing enough bandwidth to fully reconstruct high-frequency events.
A novel methodology combining field incidents with machine learning clustering algorithms is proposed to identify arrhythmic shocks signatures and whirl and bit bounce in real time, preventing failures to the BHA.
Systematic Decisions Under Uncertainty: An Experiment Towards Better Geosteering Operations
Authors: Alyaev Sergey , Holsaeter Andrew , Bratvold Reidar Brumer , Ivanova Sofija , Bendiksen Morten 
Published: March 2021

Abstract
Geosteering workflows are increasingly based on updated quantifications of subsurface uncertainties during real-time operations. These workflows give tremendous amounts of information that a human brain cannot make sense of. To advance value creation from geosteering, the industry should develop and adopt decision support systems (DSSs). DSSs might provide either expert tools which inform decisions under uncertainty or optimization-based recommendations. In both cases the adoption of a DSS would require new skillsets to dynamically and systematically interpret uncertainties and parameters required for operational decision making. The aim of this work is to identify the relevant skills and ways to aid good geosteering decisions.
We present an experiment where 54 geosteering experts took part in performing steering decisions under uncertainty in a controlled environment using an online competition platform. In the experiment we compare the decisions of the experts with an AI bot that had the same information at its disposal.
Two of the participants beat the AI bot. A survey was conducted to reveal their winning strategies. The survey shows that both of the winners had extensive prior geosteering experience. That, together with luck, allowed them to beat the AI bot. At the same time neither of the winners utilized the full potential of uncertainty tools in the platform.
While geosteering experts possess insights due to prior experience, the information in the real-time data will still be overwhelming, sometimes resulting in inconsistent and unreliable geosteering choices. The AI bot guarantees reliable and consistent decisions by optimization based on systematic uncertainty analysis. Further development of DSSs, and their use as training-simulators for experts, should lead to improved well placements through adopting well-established principles for high-quality decision-making.
The Optimal Initiation Timing of Surfactant-Polymer Flooding in a Waterflooded Conglomerate Reservoir

Published: March 2021

SummarySurfactant-polymer (SP) flooding has been regarded as an efficient technique for enhanced oil recovery in the development of mature oil fields, especially for those with heterogeneous conglomerate reservoirs. However, people are still unclear about the optimal SP flooding initiation timing (OSPT) that is expected to contribute to the maximum ultimate recovery factor in the case with a limited amount of SP solution injection. Accordingly, this study aims to investigate OSPT through conducting a series of experiments, including nuclear magnetic resonance (NMR) online monitoring, full-diameter coreflooding, and microfluidic study. The fractional-flow curve is used to identify OSPT, of which the effect on the oil recovery is analyzed. OSPT is demonstrated to be dependent on the amount of injected SP solution. An earlier-started SP flooding is favorable for achieving higher oil recovery factors under the premise of sufficiently high SP solution injection [more than 1.5 pore volume (PV)]. With the commonly used 0.65 PV of SP solution in the reservoir scale, OSPT is suggested to be at the moment when a water cut of 80 to 90% is reached. The formation of dense emulsions in the early-started SP flooding affects the performance of the post-waterflooding, which eventually decreases the ultimate oil recoveries because of inadequacy of SP solution. An earlier-started SP flooding contributes to a larger swept volume, but the initial efficiency of the SP flooding is lower than that of the waterflooding when the injection pressure is constant. OSPT is proposed through analyzing the fractional-flow curve in the case of 0.65 PV of SP injection, and the determined OSPT is validated by coreflooding experiments and field data. Moreover, OSPT for the conglomerate reservoir is suggested to be earlier than that for the relatively homogenous sandstone reservoir.

Published: March 2021

Abstract
The development of explainable news credibility prediction models is critical both for fighting the viral propagation of misinformation and improving media literacy. This work investigates a variety of content indicators approaching different semantic and discourse dimensions, such as title representativeness, reasoning errors, and sentiment intensity. These indicators were inspired by a previous study conducted for English news, aimed at reaching a collective consensus on which indicators could be widely used for predicting news credibility. This new study, performed by a multi-disciplinary team, relies on a corpus of 80 news articles from Portuguese mainstream and alternative news media, which were annotated by junior and senior journalists. The assessment of the corpus annotations provides insight into the prevalence of different indicators in each type of news source. The results obtained for Portuguese correlate in most cases with the ones reported for English, which motivates the adoption of common standards for supporting the collaborative development of interoperable automatic misinformation detection approaches.

Abstract
Background: Patient safety is a worldwide problem, and the patient contribution to mitigate the risk of patient harm is now recognized as a cornerstone to its solution. In order to understand the nature of integrating patients into patient safety and healthcare organizations and to monitor their integration, a Canadian survey tool has been co-constructed by patients, researchers and the Canadian Patient Safety Institute (CPSI). This questionnaire has been adapted from the French version of the patient engagement (PE) in patient safety (PS) questionnaire created for the province of Quebec, Canada. Methodology: The pan-Canadian PE in PS survey tool was developed in a five-step process: (1) a literature review and revision of the initial tool developed in the province of Quebec; (2) translation of the French questionnaire into English; (3) creation of a Canadian expert advisory group; (4) adaptation of the tool based on feedback from the expert advisory group (assessment and development of the construct’s dimensions, wording assessment and adaptation for pan-Canadian use, technical testing of the online platform for the survey); and (5) pilot testing and pre-validation of the tool before pan-Canadian use. Results and Conclusion: The pan-Canadian PE in PS survey tool comprises 5 sections: (1) demographic identification of the participants (Q1 to Q5); (2) general questions (Q6 to Q17); (3) the patient engagement process (experience level of participants and organizational incentives for PE in general) (Q18 to Q33); (4) PE in PS processes, such as current activities, strategies, structures, resources and factors (Q34 to Q67); and (5) the context and impact of PE in PS initiatives in Canadian healthcare organizations (CHOs) (Q68 to Q75), including outcome identification, improvement mechanisms and strategies, evaluation mechanisms, and indicators.
