Published: September 2022

Corpus linguistics has firmly established itself as a major area of research within linguistics. Arguably, one of the most practical applications of corpora and corpus linguistics has been in the area of second language (L2) acquisition research. Emerging from the integration of the fields of corpus linguistics and second language acquisition, learner corpus research has greatly enhanced our understanding of how language learners acquire and use their L2 ( Granger, 2002 ). Since its inception in the 1980s ( Granger et al., 2015 ), learner corpus research has increasingly attracted scholarly attention from around the world. This paper highlights the state of learner corpus research in New Zealand, focussing, in particular, on lexical and syntactic aspects of learner language. In doing so, it reviews the learner corpus studies carried out to date by New Zealand-based researchers, describing the results and implications of such research in the context of L2 education, and discussing the current status and future prospects of learner corpus research in New Zealand.
The Reader as Player: Exploring the Notion of Aesthetic and Efferent Gaming
Authors: Guanio-Uluru Lykke
Published: September 2022

This article argues that videogames may be considered part of the fluid cross-media landscape of children’s literature and that they require a particular sort of active reader, namely a player. Departing from the concept of cybertext and using the physics-based puzzle game Unravel (Coldwood Interactive) as a main example, the article draws on theoretical discussions from game studies (Aarseth; Jenkins; Jørgensen; Schell; Sicart; Tronstad; Zimmermann; Yee) and on Louise Rosenblatt’s distinction between efferent and aesthetic reading to discuss what kinds of player engagement may constitute aesthetic and efferent gaming.
Experimental validation of a corner stall control methodology using parametrised guide fins
Authors: Mondin Gabriel , Riéra William , Duquesne Pierre , Ottavy Xavier
Published: September 2022

Corner separation is known to limit the operability of aeronautical compressors. Dedicated control devices such as guide fins are envisioned to reduce its negative effects. This paper presents a methodology based on RANS (Reynolds-Averaged Navier-Stokes) computations enabling to select guide fins efficient for that purpose. This methodology is applied to a reference case of linear compressor cascade operating at low Mach number (∼0.11). A set of 17 parameters is used to define two design spaces of interest, from which guide fins are generated. From then, an automated process generates and merges an unstructured mesh built around each guide fin with a fixed, structured mesh of reference representing a single channel of the cascade. Finally, RANS results on the resulting hybrid mesh are obtained using the Computational Fluid Dynamics solver elsA. This set up has proven successful in evaluating automatically hundreds of guide fins of various shapes. Several geometries illustrate the diversity of the design space. A selection of guide fins is then evaluated experimentally. Evolutions of the losses downstream of the cascade are compared to their respective RANS predictions, and to the reference case without guide fin. These experimental results validate the implemented methodology and show encouraging results in terms of loss redistribution brought by the control device.

Published: September 2022

. The article analyzes the modern urban trends of street and road space redistribution, which in recent years are reflected in the regulations of Ukraine. The basic options for such redistribution are: narrowing of lanes for private transport (allowed by updated regulations in Ukraine); reducing the number of lanes for private transport (which does not always reduce the roadway capacity). As a result of foreign experience analysis the stages in which redistribution of street and road space can be carried out are revealed: pilot actions (temporary marking, road barriers and change of traffic organization); intermediate steps of reconstruction (application of new markings, installation of stationary and sliding columns, mobile flower beds, containers with young trees or bushes, large natural stones, lanterns, benches, etc.); comprehensive reorganization of streets and spaces (sidewalks widening, curbs moving, bike lanes allocating or separating, installing of elements to slow down traffic, organizational measures to optimize traffic lights, relocation of utilities, drainage and storm sewer systems, etc.). As a result of the analysis of modern tendencies in designing settlements’ streets and roads and world experience of these tendencies realization, the following principles of street and road space redistribution are formulated: the principle of equality in the right of use, based on space availability for people of any social class, age and state of health; the principle of security, which is to give citizens the opportunity to feel protected on the streets of their city; the principle of diversity of activities, which aims to provide all social groups with accessible and diverse types of recreation and leisure in public spaces; the principle of comfortable microclimate, which is to ensure the comfort of residents on the settlements streets, and the principle of aesthetics, ensuring an attractive appearance of urban spaces.

Published: September 2022

Posterosuperior rotator cuff tear (PSRCT) is one of the most common shoulder disorders in elderly people’s daily life; however, the biomechanical relationship between PSRCT and shoulder abduction function is still controversial. In this study, a total of twelve freshly frozen cadaveric shoulders were included and tested in five conditions: intact rotator cuff, 1/3 PSRCT, 2/3 PSRCT, entire PSRCT, and global RCT. In each condition, extra load (0%, 45%, and 90% failure load) was sequentially added to the distal humerus, and the function of the remaining rotator cuff was mainly evaluated via the middle deltoid force (MDF) required for abduction. It is found that the peak MDF is required for abduction did not differ among the three PSRCT conditions (1/3 PSRCT: 29.30 ± 5.03 N, p = 0.96; 2/3 PSRCT: 29.13 ± 9.09 N, p = 0.98; entire PSRCT: 28.85 ± 7.12 N, p = 0.90) and the intact condition (29.18 ± 4.99 N). However, the peak MDF significantly differed between the global RCT (76.27 ± 4.94 N, p < 0.01) and all PSRCT and intact conditions. Under 45% failure load, the MDF of the entire PSRCT and global tear conditions were significantly increased compared with another status. With the 90% failure load, only the 1/3 PSRCT condition maintained the same shoulder function as the intact rotator cuff. These biomechanical testing jointly suggested that the weight-bearing ability of the shoulder significantly decreased as PSRCT progressed.

Published: September 2022

The design of bionic bone scaffolds to mimic the behaviors of native bone tissue is crucial in clinical application, but such design is very challenging due to the complex behaviors of native bone tissues. In the present study, bionic bone scaffolds with the anisotropic mechanical properties similar to those of native bone tissues were successfully designed using a novel self-learning convolutional neural network (CNN) framework. The anisotropic mechanical property of bone was first calculated from the CT images of bone tissues. The CNN model constructed was trained and validated using the predictions from the heterogonous finite element (FE) models. The CNN model was then used to design the scaffold with the elasticity matrix matched to that of the replaced bone tissues. For the comparison, the bone scaffold was also designed using the conventional method. The results showed that the mechanical properties of scaffolds designed using the CNN model are closer to those of native bone tissues. In conclusion, the self-learning CNN framework can be used to design the anisotropic bone scaffolds and has a great potential in the clinical application.

Monitoring and measurement of carbon dioxide (CO2) is critical for many fields. The gold standard CO2 sensor, the Severinghaus electrode, has remained unchanged for decades. In recent years, many other CO2 sensor formats, such as detection based upon pH-sensitive dyes, have been demonstrated, opening the door for relatively simple optical detection schemes. However, a majority of these optochemical sensors require complex sensor preparation steps and are difficult to control and repeatably execute. Here, we report a facile CO2 sensor generation method that suffers from none of the typical fabrication issues. The method described here utilizes polydimethylsiloxane (PDMS) as the flexible sensor matrix and 1-hydroxypyrene-3,6,8-trisulfonate (HPTS), a pH-sensitive dye, as the sensing material. HPTS, a base (NaOH), and glycerol are loaded as dense droplets into a thin PDMS layer which is subsequently cured around the droplet. The fabrication process does not require prior knowledge in chemistry or device fabrication and can be completed as quickly as PDMS cures (∼2 h). We demonstrate the application of this thin-patch sensor for in-line CO2 quantification in cell culture media. To this end, we optimized the sensing composition and quantified CO2 in the range of 0–20 kPa. A standard curve was generated with high fidelity (R2 = 0.998) along with an analytical resolution of 0.5 kPa (3.7 mm Hg). Additionally, the sensor is fully autoclavable for applications requiring sterility and has a long working lifetime. This flexible, simple-to-manufacture sensor has a myriad of potential applications and represents a new, straightforward means for optical carbon dioxide measurement.

Solid state electrolytes have been intensively studied in the solid oxide fuel cells (SOFCs). The aim of this work is to investigate the effects of MgO and Fe2O3 dual sintering aids on the microstructure and electrochemical properties of solid state Gd0.2Ce0.8O2-δ (GDC) electrolytes, which are prepared by a sol-gel method with MgO and Fe2O3 addition to the GDC system. It is found that the addition of MgO and Fe2O3 can reduce the sintering temperature, increase densification and decrease the grain boundary resistance of the electrolyte. The 2 mol% MgO and 2 mol% Fe2O3 co-doped GDC (GDC-MF) exhibits the highest grain boundary conductivity. At 400°C, the grain boundary conductivity and total conductivity of GDC-MF are 15.89 times and 5.56 times higher than those of GDC. The oxygen reduction reaction (ORR) rate at the electrolyte/cathode interface of GDC-MF is 47 % higher than that of GDC. Furthermore, the peak power density of a single cell supported by GDC-MF is 0.45 W cm−2 at 700°C, 36.7% higher than that of GDC. Therefore, the GDC-MF should be a promising electrolyte material for intermediate-temperature solid oxide fuel cells (IT-SOFCs).
Adipocyte commitment of 3T3-L1 cells is required to support human adenovirus 36 productive replication concurrent with altered lipid and glucose metabolism

Published: September 2022

Human adenovirus 36 (HAdV-D36) can cause obesity in animal models, induces an adipogenic effect and increased adipocyte differentiation in cell culture. HAdV-D36 infection alters gene expression and the metabolism of the infected cells resulting in increased glucose internalization and triglyceride accumulation. Although HAdV-D36 prevalence correlates with obesity in humans, whether human preadipocytes may be targeted in vivo has not been determined and metabolic reprogramming of preadipocytes has not been explored in the context of the viral replication cycle. HAdV-D36 infection of the mouse fibroblasts, 3T3-L1 cells, which can differentiate into adipocytes, promotes proliferation and differentiation, but replication of the virus in these cells is abortive as indicated by short-lived transient expression of viral mRNA and a progressive loss of viral DNA. Therefore, we have evaluated whether a productive viral replication cycle can be established in the 3T3-L1 preadipocyte model under conditions that drive the cell differentiation process. For this purpose, viral mRNA levels and viral DNA replication were measured by RT-qPCR and qPCR, respectively, and viral progeny production was determined by plaque assay. The lipogenic effect of infection was evaluated with Oil Red O (ORO) staining, and expression of genes that control lipid and glucose metabolism was measured by RT-qPCR. In the context of a viral productive cycle, HAdV-D36 modulated the expression of the adipogenic genes, C/EBPα, C/EBPβ and PPARγ, as well as intracellular lipid accumulation, and the infection was accompanied by altered expression of glucolytic genes. The results show that only adipocyte-committed 3T3-L1 cells are permissive for the expression of early and late viral mRNAs, as well as viral DNA replication and progeny production, supporting productive HAdV-D36 viral replication, indicating that a greater effect on adipogenesis occurs in adipocytes that support productive viral replication.

Background and objective

Urine culture is time consuming, which may take days to get the results and impede further timely treatment. Our objective is to evaluate whether the fast urinalysis and bacterial discrimination system called Sysmex UF-5000 may predict urinary tract infections (UTIs) (within minutes) compared with the clinical routine test in suspected UTI patients. In addition, we aimed to explore the accuracy of microbiologic information by UF-5000.

Materials and Methods

Consecutive patients who were admitted from the emergency department at Queen Mary Hospital (a tertiary hospital in Hong Kong) from June 2019 to February 2020 were enrolled in the present study. The dipstick test, manual microscopic test with culture, and Sysmex UF-5000 test were performed in the urine samples at admission.

Results

A total of 383 patients were finally included in the present study. UF-5000 urinalysis (area under the receiver operator characteristic curve, AUC=0.821, confidence interval, 95%CI: 0.767–0.874) outperformed the dipstick test (AUC=0.602, 95%CI: 0.550–0.654, P=1.32×10-10) for predicting UTIs in patients without prior antibiotic treatment. A significant net benefit from UF-5000 was observed compared with the dipstick test (NRI=39.9%, 95%CI: 19.4–60.4, P=1.36 × 10-4). The urine leukocyte tested by UF-5000 had similar performance (AUC) for predicting UTI compared with the manual microscopic test (P=0.27). In patients without a prior use of antibiotics, the concordance rates between UF-5000 and culture for predicting Gram-positive or -negative bacteriuria and a negative culture were 44.7% and 96.2%, respectively.

Conclusions

UF-5000 urinalysis had a significantly better predictive value than the dipstick urine test for predicting UTIs.
Drivers of migration intentions in the Volta Delta: Investigating the effect of climate-related hazards and adaptation strategies

The decision to migrate involves multiple causes and motivations with environmental factors subsumed by economic and other dimensions. Deltas are rich in natural resources but are also vulnerable to environmental hazards making them a hotspot for out-migration. In spite of some infrastructural interventions, specifically in the Volta Delta, to minimize the environmental effects, there is scant evidence of their impacts on livelihoods and the potential to reverse out-migration trends and aspirations. Additionally, there is little knowledge on the key drivers of migration in the area. Using data from the 2016 DECCMA household survey in Ghana, we found that exposure to drought does not trigger migration intentions, however, exposure to erosion and salinity do. Households capable of diverse adaptation options have a higher likelihood of migration intention. Households whose main livelihood is ecosystem-based were less likely to have the intention to migrate compared with those whose livelihoods were non-ecosystem based. The study provides insights into future migration intentions and drivers of migration in the Volta Delta.
Transcatheter and surgical treatment of tricuspid regurgitation: Predicting right ventricular decompensation and favorable responders
Authors: Sala Alessandra , Beneduce Alessandro , Maisano Francesco
Published: September 2022

Isolated tricuspid regurgitation (TR) has gained increasing recognition in recent years both in the surgical and in the cardiological community. Left untreated, isolated TR significantly worsens survival. Despite being a strong predictor of negative prognosis, interventions to correct TR are rarely performed due to increased surgical risk and late patient presentation. Recently, the ultimate focus has been on patient selection, surgical or transcatheter indication, and correct timing. Furthermore, of paramount importance is the identification of predictors of outcome following treatment, in order to discriminate between favorable and unfavorable responders and guide the decision-making process of the most adequate treatment for every patient.
