A typology of secondary research in Applied Linguistics
Authors: Chong Sin Wang , Plonsky Luke 
Published: March 2023

Abstract
Secondary research is burgeoning in the field of Applied Linguistics, taking the form of both narrative literature review and especially more systematic research synthesis. Clearly purposed and methodologically sound secondary research contributes to the field because it provides useful and reliable summaries in a given domain, facilitates research dialogues between sub-fields, and reduces redundancies in the published literature. It is important to understand that secondary research is an umbrella term that includes numerous types of literature review. In this commentary, we present a typology of 13 types of well-established and emergent types of secondary research in Applied Linguistics. Employing a four-dimensional analytical framework, focus, review process, structure, and representation of text of the 13 types of secondary research are discussed, supported by examples. This article ends with recommendations for conducting secondary research and calls for further inquiry into field-specific methodology of secondary research.
Nondestructive microstructural characterization of austempered ductile iron

Published: March 2023

AbstractAustempered ductile iron (ADI) has been preferred in a wide range of applications due its unique combination of high strength, good ductility, wear resistance and fracture toughness together with lower cost and lower density compared to steels. Magnetic Barkhausen noise (MBN) measurement offers a better alternative to traditional characterization techniques by being fast and non-destructive. A simple linear regression using only one single independent variable cannot correlate the MBN with the microstructure of ADI, since its microstructure is multi-component. Multiple linear regression analysis (MLRA) was used to build a model that uses the characteristic features of microstructural constituents as input parameters to predict the MBN. For that purpose, Cu-Ni-Mo alloyed ductile iron samples austempered between 325 and 400 °C and for 45–180 min duration were used. The results show that MBN is most sensitive to the size and shape of acicular ferrite and retained austenite. Moreover, MBN is almost insensitive to the size, morphology and volume fraction of graphite particles. This indicates that retained austenite pins the domain walls more effectively than the graphite particles. Considering the results MLRA, MBN technique can be used to characterize the ausferritic microstructure of ADI.
Effects of deep cryogenic treatment with different holding times on the mechanical properties of Al 7050-T7451 alloy friction stir welding
Authors: Özbek Onur 
Published: March 2023

Abstract
This study aimed to improve mechanical properties, which decreased in the weld area, with deep cryogenic treatment at different holding times. In the study, firstly, the formation of heat damaging the welding area was observed. The temperatures in the welding zone were measured on the shoulder with a thermal camera, on the material surface, and inside the material with a thermocouple. The effects of these temperatures during welding on the surface topography and mechanical properties were investigated. The effect of tempering heat treatment after deep cryogenic treatment applied for 6, 12, 18, and 24 h was investigated. It has been observed that tempering after cryogenic treatment applied to 7xxx series aluminum alloys reduces the hardness of the nugget zone but increases the hardness in the heat unaffected zone. In addition, it was observed that deep cryogenic treatment applied at different holding times positively affected the hardness, tensile strength, and % elongation in the weld area.
Comparison of notch fabrication methods on the impact strength of FDM-3D-printed PLA specimens
Authors: Eryildiz Meltem 
Published: March 2023

Abstract
In this study, the effect of the notch fabrication method (printing the notch on the part, and machining the notch) on the impact results of 3D-printed polylactic acid (PLA) was investigated. Sensitivity to build orientation was also noted in both test situations. The impact test specimens were printed using an FDM-based printer with or without a notch at various build and print orientations. Un-notched specimens were then machined to create notches. To simulate the impact effects, Ansys software was employed to create a finite element model, and the results of the finite element analysis were consistent with the experimental results. According to the findings, the impact strength of the specimens with 3D-printed notches increased by 11–38% compared to specimens whose notch was machined after the rectangular bars were 3D printed. In addition, it has been observed that the build and print orientations affect the impact strength.

Authors: Vogel Danny , Hembus Jessica , Bader Rainer 
Published: March 2023

Abstract
Revision ceramic heads with titanium adapter sleeves are used in case of a femoral head revision in total hip arthroplasty to avoid ceramic fracture due to damaged tapers. Objective of the present study was to evaluate the taper connection strength of revision ceramic heads. Therefore, revision ceramic heads (Ø36 mm; adapter sleeve S) and standard ceramic heads (Ø36 mm; neck length S) were assembled with an axial load (2 kN) to titanium tapers with various damage modes (undamaged, truncated, and elevated). Subsequently, the heads were either pulled-off directly after assembly or after dynamic loading over 2.5 million cycles (sinusoidal 0.3 kN–3.0 kN). Pull-off forces of the revision heads (1.24 kN–1.66 kN) were up to 43.7% higher compared to standard heads (1.02 kN–1.48 kN) in dependency of the taper damage. After dynamic loading, the pull-off forces did not change in case of standard heads. The pull-off forces of the revision heads decreased in combination with the undamaged and truncated tapers but increased in combination with the elevated tapers. In conclusion, revision heads with adapter sleeves (size S) showed higher taper connection strength than standard heads both on undamaged and damaged tapers.

Published: March 2023

Abstract
Shear strain rate effect on crystallisation behaviour and characteristic temperatures of the three well-known glass formers in Cu–Zr binary amorphous system, namely Cu50Zr50, Cu56Zr44 and Cu64Zr36, were investigated. The crystallisation behaviour of Cu64Zr36 was uniquely found to be heavily dependent on shear strain rate. Crystallisation kinetics were studied through Isochronal transformation and isothermal transformation. The activation energy of crystallisation of each case was compared and contrasted. Johnson-Mehl-Avrami (JMA) analyses were also employed to study its kinetics behaviour. Finally, high angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) combined with laser-assisted local electrode atom probe (LEAP) investigation revealed no detectable clustering or phase separation.
Terahertz nanofuse by a single nanowire-combined nanoantenna
Authors: Choi Geunchang , Roh Yeeun , Seo Minah 
Published: March 2023

Abstract
We propose a terahertz nanofuse through irreversible modulations in transmitted terahertz using nanowires-combined nanoantenna structures. Semiconductor and metal nanowires show irreversible reconfiguration in their geometry at an incident field of 20 kV/cm. The concept can be explained by terahertz-field-induced ionization or electromigration. A strongly localized field due to geometrical conditions causes a floated metal nanowire from one side of a metal nanoantenna to touch the opposite side, bridging two separate metal plates and creating a junction. For the bridged nanoantenna, the highly enhanced field induced the breaking of the connection across the metal sides of a nanoantenna. In the bridging and breaking cases, permanent transformation occurs in opposite structural forms. It encompasses a potential application as an optical fuse to protect sensitive terahertz devices under excessive field focus.
Sensitivity enhanced tunable plasmonic biosensor using two-dimensional twisted bilayer graphene superlattice
Authors: Du Fusheng , Zheng Kai , Zeng Shuwen , Yuan Yufeng 
Published: March 2023

Abstract
This study theoretically demonstrated an insight for designing a novel tunable plasmonic biosensor, which was created by simply stacking a twisted bilayer graphene (TBG) superlattice onto a plasmonic gold thin film. To achieve ultrasensitive biosensing, the plasmonic biosensor was modulated by Goos–Hänchen (GH) shift. Interestingly, our proposed biosensor exhibited tunable biosensing ability, largely depending on the twisted angle. When the relative twisted angle was optimized to be 55.3°, such a configuration: 44 nm Au film/1-TBG superlattice could produce an ultralow reflectivity of 2.2038 × 10−9 and ultra-large GH shift of 4.4785 × 104 µm. For a small refractive index (RI) increment of 0.0012 RIU (refractive index unit) in sensing interface, the optimal configuration could offer an ultra-high GH shift detection sensitivity of 3.9570 × 107 µm/RIU. More importantly, the optimal plasmonic configuration demonstrated a theoretical possibility of quantitatively monitoring severe acute respiratory syndrome coronavirus (SARS-CoV-2) and human hemoglobin. Considering an extremely small RI change as little as 3 × 10−7 RIU, a good linear response between detection concentration of SARS-CoV-2 and changes in differential GH shift was studied. For SARS-CoV-2, a linear detection interval was obtained from 0 to 2 nM. For human hemoglobin, a linear detection range was achieved from 0 to 0.002 g/L. Our work will be important to develop novel TBG-enhanced biosensors for quantitatively detecting microorganisms and biomolecules in biomedical application.

Published: March 2023

Abstract
A three-dimensional simulation model of the electromechanical control system was built using the fuzzy control proportional–integral–derivative (PID) adjustment algorithm after an automatic electromechanical control system based on programmable logic controller (PLC) technology was optimized to achieve the practical use of electromechanical program control. First, the hardware of the electromechanical control system is discussed and designed. The findings demonstrate the viability of the mechanical and electrical integration PLC program optimization solution based on three-dimensional (3D) model. The system has a higher control and management efficiency, which is 30% greater than that of the conventional system. The mechatronic manufacturing system’s continuous operation efficiency enhancement can significantly lower the investment costs and boost the financial gains of industrial organizations. Traditional systems have a control and management efficiency of around 30%, but automatic electromechanical control systems based on PLC technology and created using 3D models have a control and management efficiency between 60 and 70%.

Published: March 2023

Abstract
Natural pigskin was subjected to cryogrinding before extraction, and effects of the approach on extraction rate, structure, and properties of collagen were prospected systematically. It was found that the extraction rate multiplied gradually from 22% to 40% with an extended grinding duration from 0 to 20 min. Compared with natural collagen, the ground one soared by about 80% concerning the net yield. Electrophoresis revealed the stereo structures of the extracted collagen were not destroyed when ground, while a small amount of it degraded accordingly, whose conclusion was further corroborated by circular dichroism (CD) and infrared spectrometry. Results from contact angle (CA) test clarified that the hydrophilicity of collagen enhanced with prolonged grinding. Moreover, analysis of fibrillogenesis behavior verified that, after grinding, the assembly rate for collagen in the turbidity assay dented with a lengthened equilibrium time; finer fibril network with larger pore size and weakened elasticity was later observed. Methyl thiazolyl tetrazolium (MTT) analysis manifested that ground collagen was more conducive to cell proliferation. This polymer processing approach not only provides us with a facile approach to manipulate capacities of collagen but also sheds light on other potential substances beneath the same principle.

Published: March 2023

Abstract
In 1957 there occurred a technological disaster in the Southern Urals in the form of a nuclear accident at the Mayak chemical plant in Ozersk, Soviet Union. The accident led to the resettlement of two historical centres of the first wave of the Russian colonization of the region, as the villages along the Techa river were declared restricted areas during the cleaning of the radiation trail, and their residents were resettled. As a result, the original culture of the villages was lost. The inspiration for our research is Alexey Mityunin, a local historian, enthusiast, and public activist, who collected a martyrology of the disappeared Ural villages. This paper presents the results of field expeditions to Brodokalmak carried out in 2014–2017 by students of the Miass Branch of Chelyabinsk State University, Russia. Brodokalmak is the village where the people resettled from contaminated lands Zamanikha, Boevka, and Muslyumovo live or lived.
Breaking the Carbon Lock-In Effect in Post-disaster Rebuilding: A Case Study of a Wenchuan Earthquake-Stricken City in China
Authors: Jiang Wei 
Published: March 2023

Abstract
While post-disaster rebuilding is an urgent task for affected areas, an approach without consideration for climate protection will probably lead to another disaster of carbon lock-in. Therefore, policymaking and implementation are critically important. This paper takes the Guangyuan prefecture as a case study, where the local government took the lead in low-carbon initiative and made a great contribution to low-carbon development. Based on long-term field investigations and semi-structured interviews, using the theory of multi-level governance, it discusses policy formation and implementation in the Guangyuan prefecture, and how the governance system promoted an environment-and-climate-friendly rebuilding. The results demonstrate the urgency of carbon decoupling in post-disaster-rebuilding and the significance of an effective governance system. This provides insight to the contemporary world that post-disaster rebuilding is not only a revitalization of the affected areas, but a comprehensive undertaking to avoid other possible disasters and ensure a sustainable future.

Published: March 2023

Abstract
On 26 April 1986, the accident at the Chernobyl nuclear power plant in Soviet Ukraine led to a massive disaster, the consequences of which affected millions of people in northern and eastern Europe. Today, 35 years later, we recall it not only as one of the greatest catastrophes in the history of nuclear power but also as one of the main political preconditions or factors that led to the end of the USSR. This paper presents the initial stage of a comparative study on the memories of this disastrous event among Ukrainians, Belarusians, Russians, and Bulgarians living on the periphery of the affected zone. The aim is to trace diverse aspects of public reflection in connection with people’s awareness and the degree to which they were affected, the reactions to the disaster, its effects and consequences, the preparedness of the population, and the latter’s assessment of post-disaster management.
Integration of a transonic high-pressure turbine with a rotating detonation combustor and a diffuser
Authors: Liu Zhe , Braun James , Paniagua Guillermo 
Published: March 2023

Abstract
In this paper, a diffuser is used to integrate a transonic high-pressure turbine with a rotating detonation combustor (RDC). The paper focuses on the required design modifications to the turbine endwalls (EW) to enable high efficiency, while preserving the airfoil blade-to-blade geometry. The main challenge is the stator passage unstarting, due to the high inlet Mach number. First of all, steady Reynolds Averaged Navier Stokes simulations were performed to compare the efficiency of turbines with constant-radius EWs to turbines with axisymmetric EWs. A modified EW design prevented the unstarting of the stator passage, enabling a significant gain in performance. Afterward, the influence on the turbine efficiency and damping due to the unsteadiness from the diffuser-like fluctuations of the RDC was evaluated with unsteady Reynolds Averaged Navier Stokes simulations with a mixing plane approach (MPA). Full unsteady simulations were carried out on selected inlet conditions and compared to the mixing plane results. This parametric study provides turbine designers with recommended diffusion rates along the vane EWs. Additionally, we provide guidance on the upstream diffuser design, specifically the required damping and outlet Mach number.

AbstractFunctional connectivity within resting-state networks (RSN-FC) is vital for cognitive functioning. RSN-FC is heritable and partially translates to the anatomic architecture of white matter, but the genetic component of structural connections of RSNs (RSN-SC) and their potential genetic overlap with RSN-FC remain unknown. Here, we perform genome-wide association studies (Ndiscovery= 24,336;Nreplication= 3412) and annotation on RSN-SC and RSN-FC. We identify genes for visual network-SC that are involved in axon guidance and synaptic functioning. Genetic variation in RSN-FC impacts biological processes relevant to brain disorders that previously were only phenotypically associated with RSN-FC alterations. Correlations of the genetic components of RSNs are mostly observed within the functional domain, whereas less overlap is observed within the structural domain and between the functional and structural domains. This study advances the understanding of the complex functional organization of the brain and its structural underpinnings from a genetics viewpoint.

AbstractInterferon‐induced transmembrane protein 3 (IFITM3) is an antiviral protein that alters cell membranes to block fusion of viruses. Conflicting reports identified opposing effects of IFITM3 on SARS‐CoV‐2 infection of cells, and its impact on viral pathogenesis in vivo remains unclear. Here, we show that IFITM3 knockout (KO) mice infected with SARS‐CoV‐2 experience extreme weight loss and lethality compared to mild infection in wild‐type (WT) mice. KO mice have higher lung viral titers and increases in inflammatory cytokine levels, immune cell infiltration, and histopathology. Mechanistically, we observe disseminated viral antigen staining throughout the lung and pulmonary vasculature in KO mice, as well as increased heart infection, indicating that IFITM3 constrains dissemination of SARS‐CoV‐2. Global transcriptomic analysis of infected lungs shows upregulation of gene signatures associated with interferons, inflammation, and angiogenesis in KO versus WT animals, highlighting changes in lung gene expression programs that precede severe lung pathology and fatality. Our results establish IFITM3 KO mice as a new animal model for studying severe SARS‐CoV‐2 infection and overall demonstrate that IFITM3 is protective in SARS‐CoV‐2 infections in vivo.
Visfatin increases the invasive potential of ovarian granulosa tumor spheroids by reprogramming glucose metabolism
Authors: Gogola-Mruk Justyna , Marynowicz Weronika , Krawczyk Kinga , Ptak Anna 
Published: March 2023

In brief
The role of visfatin in ovarian granulosa cell tumor (GCT) invasion and glucose metabolism reprogramming is largely unexplored. These studies imply that visfatin or its inhibitor is involved in regulating ovarian granuloma invasion by reprogramming glucose metabolism and may be a potential candidate for the diagnosis and treatment of ovarian GCT.

Abstract
Visfatin is an adipokine with nicotinamide phosphoribosyltransferase (NAMPT) activity, the concentration of which is higher in ascitic fluid than in serum, and is associated with ovarian cancer peritoneal dissemination. Potentially important effects of visfatin on glucose metabolism have been previously reported. However, the mechanism underlying the effects of visfatin on ovarian cancer cell invasion, and whether this involves altered glucose metabolism, has not been elucidated. Here, we tested the hypothesis that visfatin, which can reprogram cancer metabolism, promotes invasion by ovarian cancer spheroids. Visfatin increased glucose transporter (GLUT)1 expression and glucose uptake in adult granulosa cell tumor-derived spheroid cells (KGN) and also increased the activities of hexokinase 2 and lactate dehydrogenase. We showed a visfatin-induced increase in glycolysis in KGN cells. Moreover, visfatin increased the potential invasiveness of KGN spheroid cells by upregulating MMP2 (matrix metalloproteinase 2) and downregulating CLDN3 and CLDN4 (claudin 3 and 4) gene expression. Interestingly, an inhibitor of GLUT1 and lactate dehydrogenase (LDHA) abolished the stimulatory effect of visfatin on the potential invasiveness of KGN cells. More importantly, silencing expression of the NAMPT gene in KGN cells demonstrated its important effect on glycolysis and invasiveness in adult granulosa cell tumor cells (AGCTs). In summary, visfatin appears to increase AGCT invasiveness through effects on glucose metabolism and to be an important regulator of glucose metabolism in these cells.

Análisis acerca de la presencia de la música en los textos de Francisco Umbral, materia que en principio, no suponía motivo de interés para él porque, según propia confesión, no la entendía, aunque de manera reiterada acude a temas y descripciones relacionados con el fenómeno musical
