Creole prestige beyond modernism and methodological nationalism
Authors: Schneider Britta 
Published: December 2020

AbstractIn this article, I develop an ethnographic view on social discourses associated with language use in a Belizean village in order to access the setting’s complex and not always easy to grasp patterns of linguistic prestige. Analyzing interview and observational data on language ideologies, I show that relationships of prestige are not necessarily neatly ordered and binary but that different language ideologies, in some cases relating to the same linguistic resources, may exist side-by-side. Therefore, linguistic resources may have several indexical, social-semiotic meanings at the same time. In these, the national and educational elite is not always a central point of orientation. Other cultural values, linking to colonial histories, African imaginaries, resistance towards standardization, transnational ties or the ability to keep codes apart, may have an influence on local language ideologies and thus also the language uses in this cultural context. Binary linguistic models like thediglossiaor thecontinuum model, which map language variation in binary or linear fashions, are characteristic of epistemological traditions of Western linguistics that impact on but may also conceal complex language ideological realities in a postcolonial setting like Belize.
Between the translator and norms
Authors: Guo Huarui 
Published: December 2020

AbstractThe paper explores the tension between the translator and target-cultural norms, using the British missionary, Timothy Richard (1845–1919), and his translation ofLooking Backward: 2000–1887in the late Qing dynasty as a case study. The study integrates a sociological framework as proposed by Pierre Bourdieu into Descriptive Translation Studies as developed by Gideon Toury. The related concepts include ‘norms’, ‘habitus’, ‘field’, and ‘capital’. Given that the translator was a professional missionary and not a professional translator, the dynamics of the translator’s habitus are connected with his professional role as a missionary and his position-taking in the broader social, cultural, and political contexts of the late Qing dynasty. The translator’s translation strategy at both the macro and micro levels are analyzed and interpreted. Interpretations are based on the translator’s habitus reconstructed from his early experiences and his position-taking in the broader context. The case study reveals the tension between the translator’s habitus and target-cultural norms, which in turn sheds some light on the situation in which missionaries found themselves in late Qing society.
Limited-transpiration rate under high atmospheric vapour pressure deficit: a trait for developing genotypes for water-deficit conditions.
Authors: Ghanem Michel Edmond , Sinclair Thomas R. 
Published: December 2020

Abstract
Water deficits are the major limitation in increasing crop yields in many regions of the world. Various plant traits that might result in yield increases in water-limited environments have been discussed for decades. Conservative use of soil water is an important breeding strategy in drought-prone environments that can be achieved by traits based on partial stomatal closure under specific environmental conditions to limit transpiration rate (TR). The focus of this review is on a specific trait for conservative soil water that results in partial stomatal closure that can be supported by a plant. This limit on TR is expressed in terms of the atmospheric vapour pressure deficit (VPD) at which partial stomatal closure occurs. The review provides the physiological background of partial stomatal closure under elevated VPD. Simulation studies that analyse the potential benefits of this trait are also discussed. Finally, we provide a review of the various research that has been made in the identification of genetic variability of this trait in major crops.

Abstract
Structural, mechanical, thermal and magnetic properties of Quaternary Heusler alloys (QHA) CrFeTiZ (Z = Al, Si, Ge, Ga) are determined by employing full potential - linearized augmented plane wave (FP-LAPW) method using density functional theory (DFT). Geometry optimization of all these QHAs is accomplished and Type 2 is found the most stable. Elastic parameters reveal the mechanical stability and ductile behavior of all considered alloys. The calculated Debye Temperature (θ
D) assured that these alloys can be appropriate for high temperature devices due to high thermal conductivity (

κ

) and melting temperature (Tmelt). All these compounds are half metallic (HM) in nature as the band gap (Eg) is present in one spin orientation. The values of Eg for CrFeTiAl and CrFeTiGa are 0.68 eV and 0.86 eV respectively which are obtained by employing generalized gradient approximation (GGA) while Hubbard parameter (U) with GGA is used to calculate Eg of CrFeTiGe and CrFeTiSi and the Eg are 0.93 eV and 0.9 eV. The calculated magnetic moment (MM) of CrFeTiZ (Z = Al, Si, Ge, Ga) alloys agrees with Slater-Pauling rule (SPR). From the obtained results it is envisaged that these materials are suitable candidates for spintronic and high temperature devices.

Abstract

Objective. Estimation of finger kinematics is an important function of an intuitive human–machine interface, such as gesture recognition. Here, we propose a novel deep learning method, named long exposure convolutional memory network (LE-ConvMN), and use it to proportionally estimate finger joint angles through surface electromyographic (sEMG) signals. Approach. We use a convolution structure to replace the neuron structure of traditional long short-term memory (LSTM) networks, and use the long exposure data structure which retains the spatial and temporal information of the electrodes as input. The Ninapro database, which contains continuous finger gestures and corresponding sEMG signals was used to verify the efficiency of the proposed deep learning method. The proposed method was compared with LSTM and Sparse Pseudo-input Gaussian Process (SPGP) on this database to predict the ten main joint angles on the hand based on sEMG. The correlation coefficient (CC) was evaluated using the three methods on eight healthy subjects, and all the methods adopted the root mean square (RMS) features. Main results. The experimental results showed that the average CC, root mean square error, normalized root mean square error of the proposed LE-ConvMN method (0.82 ± 0.03,11.54 ± 1.89,0.12 ± 0.013) was significantly higher than SPGP (0.65 ± 0.05, p < 0.001; 15.51 ± 2.82, p < 0.001; 0.16 ± 0.01, p < 0.001) and LSTM (0.64 ± 0.06, p < 0.001; 14.77 ± 3.21, p < 0.001; 0.15 ± 0.02, p = < 0.001). Furthermore, the proposed real-time-estimation method has a computation cost of only approximately 82 ms to output one state of ten joints (average value of 10 tests on TitanV GPU). Significance. The proposed LE-ConvMN method could efficiently estimate the continuous movement of fingers with sEMG, and its performance is significantly superior to two established deep learning methods.

Abstract
The COMPASS upgrade tokamak (Panek et al 2017 Fusion Eng. Des.
123 11–16) will be a tokamak of major radius R
0 = 0.894 m with the possibility to reach high field (B
t ∼ 5 T) and high current (I
p ∼ 2 MA). The machine should see its first plasma in 2023 and H-mode plasma will be obtained from 2025. The main auxiliary heating system used to access H-mode will be 4 MW of neutral beam injection (NBI) power. The NBI will have a nominal injection energy of 80 keV, a maximum injection radius R
tan = 0.65 m and will create a population of well-confined energetic D ions. In this contribution, our modelling studies the NBI deposition and losses when a significant edge background density of neutrals is assumed. We follow the fast ions in the 3D field generated by the 16 toroidal field (TF) coils using the upgraded EBdyna orbit solver (Jaulmes et al 2014 Nucl. Fusion
54 104013). We have implemented a Coulomb collision operator similar to that of NUBEAM (Goldston et al 1981 J. Comput. Phys.
43 61) and a charge-exchange operator that follows neutrals and allows for multiple re-ionizations. Detailed integrated modelling with the METIS code (Artaud et al 2018 Nucl. Fusion
58 105001) yields the pressure and current profiles for various sets of achievable engineering parameters. The FIESTA code (Cunningham 2013 Fusion Eng. Des.
88 3238–3247) calculates the equilibrium and a Biot–Savart solver is used to calculate the intensity of the perturbation induced by the TF coils. Initial distributions of the NBI born fast ions are obtained from the newly developed NUR code, based on Suzuki et al (1998 Plasma Phys. Control. Fusion
40 2097). We evolve the NBI ions during the complete thermalization process and we calculate the amount of NBI ions loss in the edge region due to neutralizations. Results indicate the NBI losses for various injection geometries, various engineering parameters and various assumptions on the magnitude of the background neutral densities.
The rebound effect representation in climate and energy models
Authors: Colmenares Gloria , Löschel Andreas , Madlener Reinhard 
Published: December 2020

Abstract
We review the state-of-the-art and common practice of climate and energy modeling vis-á-vis the rebound literature. In particular, we study how energy system and economy-wide models include and quantify rebound effects—the gap between actual and expected saving or the behavioral adjustment in response to an energy efficiency improvement, in terms of energy or greenhouse gas emissions. First, we explain the interaction between drivers of energy efficiency improvements, energy efficiency policies, and the rebound effect to provide a framework for a general theoretical revision from micro- to macro-economic levels. Using this classification, we analyze rebound effect representations in empirical models by four dimensions: actors (industry or the production side, and private households or the consumption side), the aggregation level (from micro- to macro-economic levels), income level (developed or developing countries), and time (short- and long-run). Furthermore, we review rebound effect studies whose models focus on three drivers of energy efficiency improvements: market-based policies, non-market-based policies, and a costless energy efficiency improvement that holds other attributes constant (zero-cost breakthrough). We find that a clear representation of one or simultaneous drivers of energy efficiency improvements is crucial to target the goals of energy savings, greenhouse gas mitigation, and welfare gains. Under this broader view, the rebound effect is one additional phenomenon to be taken into consideration. This perspective provokes and provides additional policy implications. Reporting rebound effects as a stand-alone percentage is not sufficiently informative for policy considerations and the distinction of the aggregation level is important to asses the scalability of energy efficiency policies. Finally, we identify some ideas and motivations for future research.
Linking Cortical Morphology to Interindividual Variability in Auditory Feedback Control of Vocal Production

Published: December 2020

Abstract
Speakers regulate vocal motor behaviors in a compensatory manner when perceiving errors in auditory feedback. Little is known, however, about the source of interindividual variability that exists in the degree to which speakers compensate for perceived errors. The present study included 40 young adults to investigate whether individual differences in auditory integration for vocal pitch regulation, as indexed by vocal compensations for pitch perturbations in auditory feedback, can be predicted by cortical morphology as assessed by gray-matter volume, cortical thickness, and surface area in a whole-brain manner. The results showed that greater gray-matter volume in the left inferior parietal lobule and greater cortical thickness and surface area in the left superior/middle temporal gyrus, temporal pole, inferior/superior parietal lobule, and precuneus predicted larger vocal responses. Greater cortical thickness in the right inferior frontal gyrus and superior parietal lobule and surface area in the left precuneus and cuneus were significantly correlated with smaller magnitudes of vocal responses. These findings provide the first evidence that vocal compensations for feedback errors are predicted by the structural morphology of the frontal and tempo-parietal regions, and further our understanding of the neural basis that underlies interindividual variability in auditory–motor control of vocal production.
Older and Young Adults Experience Similar Long-Term Olfactory Habituation
Authors: Mignot Coralie , Nahrath Philipp , Sinding Charlotte , Hummel Thomas 
Published: December 2020

AbstractOlfactory habituation corresponds to a decreased behavioral or perceptual response to an odor after a prolonged exposure to this odor. Our aim was to investigate whether long-term olfactory habituation and its recovery are similar in young (&lt;35 years old) and older adults (&gt;50). Fifty-seven participants were recruited for a 5-week longitudinal study. They were exposed to one of the two odors (manzanate alpha [MA], irone alpha [IA]) for 2 weeks at home. Olfactory detection thresholds for both odors were measured before and after exposure. Results showed that the two age groups behaved similarly. The long-term exposure to an odor led to a temporary increase of its detection threshold (lower sensitivity to the odor). IA thresholds were more sensitive to the duration of exposure with the odor than MA thresholds. One week after termination of exposure, participants fully recovered and even became more sensitive to both odors. No cross-habituation was found between the two odors. Our findings highlight that long-term habituation is specific to the odor exposed, behaves the same in young and older adults, and is fully reversible in both age groups after 1 week.

Abstract

Aims
Quadricuspid aortic valve (QAV) is a rare abnormality, which may cause aortic regurgitation (AR) requiring surgical intervention in some patients. The characteristics associated with aortic valve functional degeneration in patients with QAV are still unknown. The aim of this study is to describe QAV prevalence, characterize the disease by multimodality imaging, evaluate predictors of severe AR, and assess mid-term prognosis.

Methods and results
Retrospective search in imaging exams database of one tertiary centre, for patients diagnosed with QAV between January 2007 and September 2019. QAV was characterized by cardiac computed tomography, transthoracic/transoesophageal echocardiography, and cardiac magnetic resonance. A total of 160 004 exams were reviewed and eight patients with QAV were identified (50% men, mean age 53.5 ± 10.7 years). The prevalence of QAV was 0.005%. During a median follow-up of 52 months (interquartile range 16–88), there were no deaths. Seven patients (88%) had pure AR (three severe, one moderate, and three mild) and one patient (12%) had moderate AR and moderate aortic stenosis. Three patients (38%) with severe AR underwent valve surgery (two replacements and one repair). Analysis of predictors of severe AR was not statistically significant.

Conclusion
QAV is a rare congenital cardiac defect, with a prevalence of 0.005% in our study. Its predominant functional abnormality was regurgitation and about one-third of the patients required aortic valve surgery. Multimodality imaging may play a pivotal role in assessing patients with QAV with significant valve dysfunction or associated congenital heart disease and improve their treatment strategy.

Published: December 2020

Abstract

Aims
The impact of diabetes mellitus (DM) on outcomes of lower extremity revascularization (LER) for peripheral artery disease (PAD) is uncertain. We characterized associations between DM and post-procedural outcomes in PAD patients undergoing LER.

Methods and results
Adults undergoing surgical or endovascular LER were identified from the 2014 Nationwide Readmissions Database. DM was defined by ICD-9 diagnosis codes and sub-classified based on the presence or absence of complications (poor glycaemic control or end-organ damage). Major adverse cardiovascular and limb events (MACLEs) were defined as the composite of death, myocardial infarction, ischaemic stroke, or major limb amputation during the index hospitalization for LER. For survivors, all-cause 6-month hospital readmission was determined. Among 39 441 patients with PAD hospitalized for LER, 50.8% had DM. The composite of MACLE after LER was not different in patients with and without DM after covariate adjustment, but patients with DM were more likely to require major limb amputation [5.5% vs. 3.2%, P &lt; 0.001; adjusted odds ratio (aOR) 1.22, 95% confidence interval (CI) 1.03–1.44] and hospital readmission (59.2% vs. 41.3%, P &lt; 0.001; aOR 1.44, 95% CI 1.34–1.55). Of 20 039 patients with DM hospitalized for LER, 55.7% had DM with complications. These patients were more likely to have MACLE after LER (11.1% vs. 5.2%, P &lt; 0.001; aOR 1.56 95% CI 1.28–1.89) and require hospital readmission (61.1% vs. 47.2%, P &lt; 0.001; aOR 1.41 95% CI 1.27–1.57) than patients with uncomplicated DM.

Conclusions
DM is present in ≈50% of patients undergoing LER for PAD and is an independent risk factor for major limb amputation and 6-month hospital readmission.
Primary care providers’ perspectives on initiating childhood obesity conversations: a qualitative study

Published: December 2020

AbstractBackgroundPrimary care physicians (PCPs) are in a critical position for identifying, preventing and treating childhood obesity. However, a one-size-fits-all approach does not exist for having conversations about weight with families. A better understanding of how PCPs can address paediatric patients’ weight concerns is needed in order to develop effective guidelines and trainings.ObjectiveTo describe PCPs preferences and behaviours regarding weight-related conversations with paediatric patients’ and their families.MethodsTwenty PCPs affiliated with the University of Minnesota, USA, were recruited to participate in semi-structured interviews. Transcripts were analysed using inductive thematic analysis.ResultsPCP’s identified well-child visits as the most appropriate time for weight-related discussions with families. Physicians described what approaches/elements they perceived to work best during conversations: collaboration, empathy, health-focused and objective measures.ConclusionsOverall, PCPs were more comfortable with weight-related discussions during annual well-child visits and rarely initiated them during an acute visit or the first encounter with a patient. Objective measures, such as growth charts, were often utilized to start discussions. Considering a large proportion of well-child visits are missed, alternative opportunities to have discussions about healthy lifestyle behaviours should be explored. The integral role PCPs play in paediatric obesity warrants further research.

ABSTRACT
Erythromycin pollution is an important risk to the ecosystem and human health worldwide. Thus, it is urgent to develop effective approaches to decontaminate erythromycin. In this study, we successfully isolated a novel erythromycin-degrading fungus from an erythromycin-contaminated site. The erythromycin biodegradation characteristics were investigated in mineral salt medium with erythromycin as the sole carbon and energy source. The metabolites of erythromycin degraded by fungus were identified and used to derive the degradation pathway. Based on morphological and phylogenetic analyses, the isolated strain was named Curvularia sp. RJJ-5 (MN759651). Optimal degradation conditions for strain RJJ-5 were 30°C, and pH 6.0 with 100 mg L−1 erythromycin substrate. The strain could degrade 75.69% erythromycin under this condition. The following metabolites were detected: 3-depyranosyloxy erythromycin A, 7,12-dyhydroxy-6-deoxyerythronolide B, 2,4,6,8,10,12-hexamethyl-3,5,6,11,12,13-hexahydroxy-9-ketopentadecanoic acid and cladinose. It was deduced that the erythromycin A was degraded to 3-depyranosyloxy erythromycin A by glycoside hydrolase in the initial reaction. These results imply that Curvularia sp. RJJ-5 is a novel erythromycin-degrading fungus that can hydrolyze erythromycin using a glycoside hydrolase and has great potential for removing erythromycin from mycelial dreg and the contaminated environment.
