The role of auditory processing in L2 vowel learning: evidence from recasts
Authors: Zhang Wei , Liao Yi 
Published: October 2023

AbstractDeveloping adequate second language (L2) speech has increasingly become one of the important goals in today’s globalized world. The current study set out to investigate how the provision of recasts can facilitate English vowels /i/-/ɪ/ learning by Chinese native speakers and how such learning gains resulting from recasts can be tied to individual differences in auditory processing. An experimental group of thirty young adults was engaged in ten treatment sessions of recasts lasting ninety minutes each to notice and practice English vowels /i/-/ɪ/. Their learning gains were tested through a forced-choice identification task, a controlled word-reading task, and a spontaneous picture-narrative task before and after receiving recasts. A control group of the same number of participants was also included to receive comparable sessions without receiving any recasts to check for test-retest effects. Quantitative analysis showed that recasts significantly helped Chinese native speakers facilitate their learning of English vowels /i/-/ɪ/ regardless of time and lexical context. Such learning gains resulting from recasts were significantly correlated with specific constructs of auditory processing. Namely, perceptual acuity was significantly correlated with gains from recasts in identifying L2 vowels, and audio-motor integration with gains from recasts in controlled/spontaneous production of L2 vowels. The findings suggest that recasts can serve as ideal instructional techniques of L2 vowel learning for Chinese native speakers and that the auditory processing profiles of individuals can suggest how they can benefit the most from recasts.
Exploring lexical associations in English as a Lingua Franca interactions
Authors: Pang Yang 
Published: October 2023

Abstract
The current research draws on the pragmatic approach to ELF initiated by Kecskes (2019), who proposes that temporary norms and routines are created during intercultural encounters and interactions. Based on the qualitative and quantitative analysis of collocate tokens that are strongly associated with the verb phrases of see, look, hear, listen, watch, and feel, retrieved from Asian and European ELF corpora, this study demonstrates the tendency to use similar lexical associative patterns among ELF interlocutors despite their distinct linguacultural backgrounds. An analysis of the lexical associations of the verb phrases in ELF and English Native Language (ENL) corpora further confirms that ELF speakers do not conform to ENL conventions; instead, they start to develop their own norms that are characterized by specific lexical associations and formulaic expressions.
Land-Use Conflicts and an Alternative Wildlife Management Option for the Loliondo Game-controlled Area, Tanzania: Insights from a Community Survey
Authors: Minja Gileard Sifuel , Suh Jungho , Tan Yan 
Published: October 2023

Summary

This tourism case study pays attention to natural resource management conflicts surrounding the Loliondo Game-controlled Area which encompasses 4000 km
2
adjacent to Serengeti National Park and Ngorongoro Conservation Area in Tanzania. Maasai, the largest nomadic pastoralist ethnic group in Tanzania, accounts for the overwhelming majority of the population residing in the Loliondo Game-controlled Area. The Loliondo Game-controlled Area has suffered from land-use and property-right conflicts among stakeholders despite establishing a series of wildlife management policies concerning the area. Trophy-hunting tourism has been operated in the Loliondo Game-controlled Area by a transnational private corporation with the Tanzanian government’s exclusive permission. Trophy hunting conflicts with other land uses in the Loliondo Game-controlled Area, including non-consumptive tourism, pastoral livelihoods, and crop farming. Although the
Village Land Act 1999
recognizes customary rights vested with local villages to wildlife management in the Game-controlled Areas, the Maasai communities in the Loliondo Game-controlled Area have yet to reap benefits from trophy hunting or photography tourism. To identify an alternative wildlife management option preferred by the Maasai communities, a community survey was conducted in 2018. A sample of 330 households was surveyed, with 55 in each of the six selected villages in the Loliondo Game-controlled Area. The survey confirmed that the Maasai communities were not involved in the decision-making process for wildlife management. This study has found that the Maasai communities strongly support establishing a Joint Venture Wildlife Management Area of 1500 km
2
within the Loliondo Game-controlled Area, with the remaining 2500 km
2
being allocated to grazing, farming, and human settlements. Under the Joint Venture Wildlife Management Area scheme, local villages would jointly manage wildlife and be entitled to rights to manage and use wildlife and other natural resources in the region. The overwhelming majority of the participants in the community survey were optimistic that the co-management scheme would help enhance natural resource management efficiency and social equity.

Abstract
Metal halide perovskite materials have received significant attention in recent years due to their promising properties and potential applications, particularly their use as scintillator detectors, which is rapidly emerging due to their promising advantages as detectors, such as low costs, fast response, high quantum yield, strong absorption, scalability, flexibility, and emission wavelength tunability. Given the effectiveness of perovskites as α particle detectors and the potential of 10B as a neutron converter, in this paper a 10B converting layer was coupled with an all-inorganic lead halide perovskite (CsPbBr3) layer aiming to create a thermal neutron detector. Specifically, a 1 µm thin film of 10B and a 1 µm thin layer of CsPbBr3 were deposited on a suitable substrate using a laser ablation process. The fabricated detector was subjected to a comprehensive characterization, including structural, morphological, and detection properties. As output, the films exhibit macroscopically uniform behavior and good adhesion to the substrate. In terms of thermal neutron efficiency, an efficiency of (7.9 ± 0.3)% was determined with respect to a commercial detector (EJ-426), which corresponds to an intrinsic efficiency of (2.5 ± 0.1)%. Also, Monte Carlo simulations were conducted, and the optimum value of the 10B layer thickness was found to be 2.5 µm.

MXene layers. The rinsed layers were then dried using four different conditions: 1-in the air at 25 °C, 2-in the air at 80 °C, 3-in a vacuum at 25 °C, 4-in a vacuum at 80 °C. It was observed that the specific capacitance at different scan rates of the vacuum-dried samples was, on average, 30% more than that of air-dried ones. Meanwhile, the samples dried at 80 °C have exhibited a 60% increase in the specific capacitance compared to the samples dried at 25 °C. Besides drying parameters, the effect of ultra-sonication of MXene layers before drying on their electrochemical performance has also been investigated. Generally, the specific capacitance of delaminated layers was higher than that of non-delaminated ones. However, we have noticed that ultra-sonication deteriorates the capacitive stability of the samples over time. To further improve the supercapacitor electrodes, carbon coating was performed on the sample with the best electrochemical performance (sonicated and vacuum-dried at 80 °C), through a hydrothermal glucose decomposition method. The specific capacitance of the carbonized sample was 117.19 F g−1 at the scan rate of 2 mV s−1, which is 35% more than that of the pristine MXene. The MXene structures were examined by field emission scanning electron microscopy, x-ray diffraction, and Fourier transform infrared and thermogravimetric analysis. The electrochemical characteristics of the electrodes were investigated via cyclic-voltammetry, charge–discharge test, and electrochemical impedance spectroscopy.

Published: October 2023

Abstract
Large-span spatial structures, with good appearance and plasticity are mostly used nowadays in urban landmarks. During the construction process, the loads are accumulated along with the construction conditions and the responses vary from the construction paths. Hence, a safety evaluation or monitoring of the construction process appears significant. During monitoring, the installation moment of strain gauges is not always the ideally non-loading status, the absolute or real strains in the structural components are difficult to acquire. Furthermore, the displacement monitoring for all key points reduces the construction efficiency. Herein, a response-increment real-time comparison strategy of stresses and unloading point displacements within numerical analysis is announced to avoid the above shortcomings. Based on a real large-span truss structure located in China, four construction schemes are proposed and investigated by simulation method. With the proposed construction scheme and monitoring strategy, a stress and displacement monitoring for the large-span truss structure was conducted. Through the comparison between the monitoring and simulation data, the proposed strategy is verified feasible for the construction monitoring, the efficiency is accelerated and the safety is guaranteed.

Published: October 2023

Abstract
Fibrinogen, a circulating glycoprotein in the blood, is a potential biomarker of various health conditions. This work reports a flexible electrochemical sensor based on Ni–Fe layered double hydroxide (Ni–Fe LDH) coated on Nickel foam (Ni–Fe LDH/NF) to detect fibrinogen in simulated human body fluid (or blood plasma). The nanoflakes like morphology and hexagonal crystal structure of LDH, synthesized via urea hydrolysis assisted precipitation technique, are revealed by scanning electron microscopy (SEM) and powder x-ray diffraction (PXRD) techniques, respectively. The fabricated sensor exhibits linearity in a wide dynamic range covering the physiological concentration, from 1 ng ml−1 to 10 mg ml−1 , with a sensitivity of 0.0914 mA (ng/ml)−1(cm)−2. This LDH-based sensor is found to have a limit of detection (LOD) of 0.097 ng ml−1 and a limit of quantification (LOQ) of 0.294 ng ml−1 (S/N = 3.3). The higher selectivity of the sensor towards fibrinogen protein is verified in the presence of various interfering analytes such as dopamine, epinephrine, serotonin, glucose, potassium, chloride, and magnesium ions. The sensor is successful in the trace-level detection of fibrinogen in simulated body fluid with excellent recovery percentages ranging from 99.5% to 102.5%, proving the synergetic combination of 2D Ni–Fe layered double hydroxide and 3D nickel foam as a promising platform for electrochemical sensing that has immense potential in clinical applications.
Angular dependence of resistance and critical current of a Bi-2223 superconducting joint

Published: October 2023

Abstract
Low resistance and high critical current are prerequisites for superconducting joints used in persistent-mode magnets. Herein, we use a joint resistance evaluation system, previously developed by us, to systematically evaluate the angular dependence of resistance and critical current of a Bi-2223 superconducting joint in a closed-loop sample. The current decay is measured by rotating the sample incrementally. The time dependence of the loop current is evaluated at 4 K, 0.15–0.28 T, and magnetic field angles ranging from 90° to 0, wherein 90° corresponds to the direction parallel to the tape surface. The results suggest that the resistance and critical current of the joint depend on the angle of the magnetic field. The evaluated critical current increases as the angle increases. The angular dependence of resistance can be divided into three regions: low-resistance, transition, and high-resistance regions. The low-resistance region exists at high angles close to 90°. In this region, the decay of the loop current is small, and the persistent current continues to flow. Furthermore, the joint resistance is less than 1.4 × 10−13 Ω. In the transition region, the joint resistance significantly increases by three orders of magnitude with sample rotation. This significant increase is attributed to an increase in the perpendicular component of the magnetic field, which decreases the critical current of the joint. At lower angles, the joint resistance remains high, ranging from 10−11 to 10−10 Ω. A significant decay in the loop current is observed in the high-resistance region. Based on these findings, we conclude that the design of a persistent-mode magnet must consider not only the magnitude but also the direction of the magnetic field applied to superconducting joints.

Published: October 2023

Abstract
Here we present a computational study of the thermodynamic and structural properties of bulk and confined (1,1,1,3,3-pentafuorobutane). The DREIDING force field model has been used in the method of molecular dynamics. In order to study the effect of confinement we have placed (1,1,1,3,3-pentauorobutane) molecules between two graphene walls. In order to study the influence of pore loading on system behavior we have simulated systems of the same size, but with a different number of (1,1,1,3,3-pentauorobutane) molecules, from 200 to 2000. The equations of state at T = 300 K in a wide range of densities for all considered systems had a single peculiarity that is attributed to gas-liquid transition. From the two-dimensional radial distribution functions, density profile and angular distribution we have observed the systems split into layers with amorphization rather than crystallization in them.

Published: October 2023

Abstract
This research paper primarily focuses on the behavior of viscous supersonic laminar flows around the F-16’s NACA 64A-204 airfoil, while also extending its scope to Shock-Wave/Boundary-Layer Interactions. The aim is to evaluate and compare methodologies for accurately characterizing these crucial aerodynamic phenomena. A unique experimental setup was developed, featuring mock-ups of F-16 airfoil equipped with pressure taps, and tested in the Supersonic Burst Wind Tunnel AF300. Computational Fluid Dynamics simulations were conducted using Ansys Fluent 2022 R2 and were supplemented by our previously established analytical model was adapted to our specific airfoil case, following calculations of the wing section equation. Key aerodynamic parameters such as lift coefficient, drag coefficient, Local Mach numbers, and the characteristics of the shock waves formed around the airfoil were examined. The study validates the NACA 64A-204 mock-up, with average errors for key parameters and 1st and 2nd Pressure Taps between the three adopted approaches remaining below 2.5%. The findings contribute valuable insights into the fundamental physics of viscous supersonic laminar flows, offering immediate applications to the design of high-speed aircraft and other advanced aerospace technologies. Additionally, the validated mock-up enhances the research capabilities of the Supersonic Burst Wind Tunnel AF300. Ultimately, this study serves as a foundational reference for optimizing aerodynamic surfaces, thereby facilitating advancements in key vehicle performance metrics such as manoeuvrability and fuel efficiency.

Abstract
This paper is devoted to the investigation of the nonlinear dynamics of a heartbeat model. The model is based on three coupled nonlinear autonomous oscillators representing the three automatism centres of the physical heart; each of these automatism centres is represented by an autonomous Barrio-Varea-Aragon-Maini (BVAM) oscillator model. Our study includes theoretical and experimental investigations. The theoretical part consists of the analysis of fixed point(s), bifurcations, Hamiltonian energy, hysteretic behaviour and coexisting attractors. The experimental investigation includes the discretization of the mathematical model followed by its synthesis and implementation under the Vivado 2017.4 platform and its simulation and its physical implementation on the Nexys-4 Artix-7 xc7a-100T FPGA trainer board. Two R-2R network digital-to-analog converters are built to visualise the practical results on a digital storage oscilloscope; a perfect correlation is observed between the theoretical, numerical and experimental results.

Gravity waves’ modulational instability under the effect of drag coefficient in the ocean
Authors: Augustin Daïka , César Mbané Biouélé 
Published: October 2023

Abstract
The research on oceanic gravity waves interacting with a drag coefficient has drawn a lot of attention. The interaction of these waves with a drag coefficient was recently found to be significant when modeling the propagation of these gravity waves. In this framework, the configuration involving the drag coefficient is of special interest. The gravity wave considered here is chosen to be unstable to two kinds (amplitude and phase) of perturbations. Given the complexity of the process to be investigated, it is necessary for us to make use of Miles’ theory in order to better model the evolution of these gravity waves propagating in deep water under the effect of drag coefficient, using the deterministic approach (well-known as the Benjamin–Feir method), and the statistical approach (also known as Klimontovich’s statistical average method) which is used starting from the Wigner Moyal transform. This study is performed to contribute to the understanding of the drag coefficient to the amplitudes (or phases) modulations of the driven waves: modulations that can sometimes accidentally trigger unpredictable extreme gravity waves.
An active colloidal system showing parallels to a time crystal
Authors: Evers Marina , Wittkowski Raphael 
Published: October 2023

Abstract
The spontaneous breaking of symmetries is a widespread phenomenon in physics. When time translational symmetry is spontaneously broken, an exotic nonequilibrium state of matter in which the same structures repeat themselves in time can arise. This state, known as ‘time crystal’, attracted a lot of interest recently. Another relatively new research area deals with active matter. Materials consisting of colloidal particles that consume energy from their environment and propel themselves forward can exhibit intriguing properties like superfluidity that were previously known only from quantum-mechanical systems. Here, we bring together these—at first glance completely different—research fields by showing that self-propelled colloidal particles show parallels to classical continuous time crystals. We present a state diagram showing where this state of matter arises. Furthermore, we investigate its properties and analyze the interactions between the particles leading to the dynamics.
