Published: August 2021

AbstractBangladesh has made progress in advancing adolescent girls’ education, but there remain substantial evidence gaps around age and gender differences in motivations, retention, and access to education for adolescents living in urban slums. This article draws on quantitative and qualitative data collected in 2017 and 2018 by Gender and Adolescence: Global Evidence (GAGE) with adolescents aged 10–17 across three low-income areas in Dhaka to explore adolescent educational attainment, aspirations, and environmental factors that constrain both. We find high educational and professional aspirations among adolescents and their parents, with parental support being an important predictor of both current enrolment and adolescent aspirations. Location is also an important predictor of adolescent aspirations and enrolment, highlighting the importance of infrastructure and services, integration into the city, and stability of the community (including schools and facilities), along with higher incomes and better employment opportunities for households.

Significance
RAS proteins control many aspects of cellular biology in response to extracellular stimuli. These essential nodes of signal transduction interact with effector proteins that contain conserved RAS-binding domains. Mutations in RAS proteins are a common cause of cancer; hence, understanding the function of their downstream effectors is important for the development of novel therapies. In this study, we characterize the interaction between RAS and the effector protein Sin1, a critical component of the mTORC2, through biochemical and structural approaches. We discover that Sin1 contains an atypical RAS-binding domain and assess the role of this interaction in cells and mice. Moreover, we find that this interaction is dispensable for mTORC2 activity and assembly, suggesting an alternative function for Sin1 in cells.

SignificanceThere is a lack of global observational data to monitor the application of nonpharmaceutical interventions (NPI) and evaluate the effect of NPIs for pandemic management in different territories. We find that economic activity reduction inferred from NO2is a driver of case deceleration in most of the territories. The effect, however, is not linear but dampens over time, and further reductions are only associated with weaker deceleration. Over the winter of 2020/2021, nearly 1 million daily COVID-19 cases could have been avoided by optimizing the timing and strength of activity reduction in different regions relative to a scenario based on the real distribution.
Video remote interpreting for home-based cognitive assessments

Published: August 2021

Abstract
Many health and social care services are implementing video remote interpreting (VRI) to deal with supply shortages and high costs of language interpreting for linguistically diverse clients. This qualitative study examines stakeholders’ perspectives on using VRI for home-based cognitive assessments, which are routinely performed with older people during aged care assessments in Australia. We conducted 25 semi-structured interviews with clients, assessors and interpreters in Melbourne and a regional Victorian city. We found that across stakeholder groups participants usually regard VRI as an acceptable alternative to face-to-face interpreting when the latter is not possible. Freelance interpreters said VRI saved on travel time and expenditure and afforded them financial and practical benefits that enabled them to better meet the high demand for their work. However, stakeholders also pointed to the limitations of VRI, including technical challenges, sound and video quality, and difficulties with positioning equipment optimally during interviews. The assessors and interpreters agreed that VRI was inappropriate when clients are known to be cognitively impaired, and that face-to-face interpreting is necessary to support these clients and ensure assessment accuracy. We suggest that plans by health or social care services to replace face-to-face interpreting with VRI should be balanced against the needs of clients and any impacts on professional practice.
A multi-dimensional analysis of the representation of conference interpreters in the Chinese media
Authors: Du Yiwei , Wang Binhua 
Published: August 2021

Abstract
Though interpreters’ professionalism has been discussed in interpreting studies, there have been few studies on
how the general public see the image of interpreters. The present study is a multi-dimensional analysis of the image of conference
interpreters as represented by the media, which is based on a corpus of 60 news reports about interpreting and interpreters in the
Chinese media in the past 10 years. It explores the research question: How are conference interpreters represented in the Chinese
media? Through thematic and rhetorical analysis of the headlines and body texts as well as multimodal analysis of the photos in
the news reports, it is found that conference interpreters are represented by institutional conference and diplomatic
interpreters, who are in turn represented as “stars” or public celebrities of the profession; they are frequently presented along
with big events and big names, and portrayed as affiliating to power and as distant from the public. Images of female beauties
among them are also selected and “consumed” as in popular culture. This implies a discrepancy between the self-perception of the
interpreting profession and their representation by the media.
Plasmonic spin-Hall effect of propagating surface plasmon polaritons in Ni80Fe20 microstructures

Published: August 2021

Abstract
Photoexcitation and shaping of a propagating surface plasmon polariton (SPP) on silver and gold microstructures are well established and lead to the discovery of the plasmonic spin-Hall effect recently. Whereas silver is often the material of choice due to its exceptional low plasma frequency and weak damping, similar observations have not been reported for ferromagnetic metals. In this work, we report on propagating SPPs on Ni80Fe20 microstructures imaged by photoemission electron microscopy (PEEM) in combination with a tunable femtosecond laser system at MHz repetition rate. Circular dichroic (CD) images in threshold PEEM show clear edge-induced SPPs with sub-micrometer wavelength and propagation length of about 3.5 μm. Analysis of the interference patterns as well as the coupling of the optical spin angular momentum to the observed fringe fields reveal propagation characteristics exclusive to evanescent waves and the presence of the plasmonic spin-Hall effect. Our work provides direct evidence that many materials with a high plasma frequency allow for excitation and observation of propagating SPPs at the dielectric/metal interface via CD PEEM imaging, enabling magnetoplasmonic investigation of common ferromagnets on nanometer length and femtosecond time scales.
Dual-polarization topological phases and phase transition in magnetic photonic crystalline insulator

Published: August 2021

Abstract
Two-dimensional topological photonic crystals have rapidly emerged as a recent and fascinating branch of photonic research. However, most of them were limited to a specific type of polarization, TE or TM polarization. Here, we explored the dual-polarization topological phases in two-dimensional magnetic photonic crystal (PC) which are composed of ferrite rod clusters in the plasma background. Under the perturbations of the bias magnetic field and/or the cluster distortion in the unit cell, the PC exhibited dual-polarization topological phases, including the quantum Hall (QH) phase, the higher-order quantum spin Hall (HO-QSH) phase and the conventional insulator (CI) phase. We studied the topological nature of these phases by the Wilson loop, Chern number, and unidirectional edge states. Intriguingly, we showed that the HO-QSH phases could present in PC of C
3v
symmetry instead of being restricted to C
6v
symmetry. The lower symmetry enlarges the gap in the edge states, which helps for the emergence of corner states. By continuously deforming the unit cell configuration, we demonstrated the phase transition in the system was dual-polarization. Our results extend the topological phases in the PCs and pave the way for the dual-polarization topological devices and their applications.

Published: August 2021

Abstract
Annual accurate predicting is important for long-term planning of the electricity company because it always seeks to achieve the reliability and sustainability for the electrical services. The process of long term load forecasting (LTLF) is implemented in several manners depending on random variables affecting the consumption of the load. This paper introduces two different strategies that have been utilized for annual electrical peak load (PL) for Jordan. The first strategy used in this paper is based on different historical features gathered form national electric power company (NEPCO) such as (population growth, the gross domestic product of the country and the historical annual PL). The second strategy is based on the historical electrical peak load only. The work includes a comparison process using three different optimization algorithms particle swarm (PSO), grey wolf (GWO) and modified grey wolf (MGWO-based on the concept of aligned) to train a feed forward neural network (FFN). The proposed MGWO-FFN gives the best results of both the twostrategies than GWO-FFN and PSO-FFN. Results of the two strategies are presented and indicate the superiority of the second strategy on the first one.

Published: August 2021

Abstract
One of the basic contents of fuzzy mathematics is the mathematical operations of fuzzy numbers. But still some of the fuzzy mathematical operations are not determined. There are some operations between fuzzy numbers are exact and there are approximated operations. In this paper, a comparison has been presented between two different fuzzy multiplication operations. One of these two fuzzy multiplication operations is exact with using interval arithmetic cut method and the other one is an approximation method which uses a standard approximation. In the two different methods, the fuzzy numbers will be defined as triangular fuzzy numbers because the triangular fuzzy number is the most popular one between the other shapes of fuzzy numbers. A numerical example has been presented with graphical result to show the difference between them and to analyze the error.

Published: August 2021

Abstract
Homopolymer poly (vinylidene fluoride) (PVDF) thin films were fabricated via high pressure process and then PVDF film was melt into porous anodic aluminum oxide (AAO) templates to form hollow nanotubes and isothermally crystal at a certain temperature. Scanning electron microscopy (SEM) and Transmission Electron Microscope (TEM) is used to observed the microstructure of nanotubes. To explore the influence of nanopores on the crystallization and melting of PVDF, differential scanning calorimetry (DSC) is used. It turns out that crystal phase is restrained in the nanotubes and mainly exists and at high temperature within relatively large nanopores and the bulk. As for phase, the increase of isothermal crystallization temperature results in the increase of melting temperature.

Authors: Lei HAN 
Published: August 2021

Abstract
The solidity coefficient of the main coal seam in Xinjiang Coking Coal Group 1930 Coal Mine is below 0.3, which is a soft outburst coal seam with poor air permeability, a small effective range of gas drainage drilling, low porosity of soft coal seam, low gas drainage rate, and unsatisfactory drainage effect. Using directional drilling equipment to construct directional long drilling, combined with the hydraulic fracturing pump set independently developed by Xi’an Research Institute, directional drilling were constructed in the 1930 coal mine 1600 level 6# coal seam, and hydraulic fracturing was carried out. The results show that after the hydraulic fracturing of the 6# coal seam, the production has been stable for nearly 6 months. During the period, the average gas drainage rate of the drilling was 134.9m3/d (maximum 561.7m3/d), which was 2.10 times that before fracturing, The average drainage concentration is 1.90%, which is 1.45 times that before fracturing. At present, the total amount of gas drainage is 25,900 m3, which is 4 times the original amount. This technology has achieved enhanced permeability of broken soft coal seam, increased drainage volume, extended drainage time, and advanced gas outburst elimination at a long distance. It provides a technical guarantee for the enhanced permeability enhancement of the broken soft low-permeability outburst coal seam and the high-efficiency underground gas drainage.

Abstract
In order to improve the interlaminar shear property of the composites manufactured by the additive of aramid fiber (AF) reinforced with polylactic acid (PLA), the preparation process of AF reinforced thermoplastic resin composite micro-wires has been optimized, which could promote impregnated and toughness. The influence of different water bath temperatures on the interlaminar shear properties of the composites was studied. And the results showed that the largest interlaminar shear strength (ILSS) of AF/PLA composite material was 12.0 MPa, which had confirmed in the water bath temperature of 30°C. As the bath temperature increased, the interlaminar shear performance decreased, and the ILSS of composite micro-wires in 70°C water bath was 74.67% of that in 30°C water bath. The composite fiber with high impregnation degree and good toughness has laid a foundation for further research on additive manufacturing of AF/PLA composite.

Abstract
Some key temperature parameters in the process of controlled rolling and controlled cooling of N80 grade oil casing steel were simulated by heat treatment method, and the effects of different isothermal temperatures on the microstructure and mechanical properties of N80 grade oil casing steel were studied. The results show that when the isothermal temperature increases from 500 °C to 550 °C, the influence of different microstructure volume and grain size is not obvious; when the temperature reaches 600 °C, the ferrite grain coarsens obviously, the volume fraction of ferrite increases obviously, and the volume fraction of pearlite and bainite decreases obviously. In addition, when the isothermal temperature increases from 500 °C to 550 °C, the yield strength and tensile strength of the test steel increase slightly, and the plastic toughness increases obviously; but when the temperature increases to 600 °C, the yield strength and tensile strength of the test steel decrease obviously, and the plastic toughness continues to increase. The optimum isothermal treatment temperature of test steel is 550 °C.

Abstract
Fixtures are commonly used tools for CNC machine tools to clamp workpieces. Due to the high requirements for its own position and motion accuracy during the operation of a CNC machine tool, in addition to its own motion accuracy, the positioning accuracy of the fixture is also an important factor affecting the overall accuracy. In the experiment, two fixture materials of 45# and 65Mn were selected, and the two fixtures with wedge-shaped positioning surface and circular positioning surface were compared. The data showed that: 1. The accuracy of fixtures with symmetrical structures of the same material is better than fixtures with asymmetrical structures; 2. The repeated positioning accuracy of 65Mn material fixture is better than that of 45 # material fixture. Therefore, the higher the positioning accuracy of the fixture made of high hardness and good rigidity materials.

Authors: Xiaofei Xu , Yuequan Zhan , Jun Zhang 
Published: August 2021

Abstract
In order to achieve long-distance measurement and control of deep space detectors, increasing the aperture is the most direct means to improve antenna performance. However, the increase in antenna size brings structural instability and is easily affected by external environments such as temperature, gravity, and wind gusts. Aiming at the problem that temperature changes affect the antenna pointing accuracy, this paper designs and implements an antenna pointing temperature compensation model, and conducts data collection and test verification. The results show that the antenna pointing accuracy can be compensated effectively under a large temperature environment by the method proposed in this paper, and the received signal strength is improved.

In view of the difficult problems of low-frequency noise reduction, based on the clamping boundary-type acoustic metamaterial theory with negative effective mass density, a structure combining membrane-type and clamping boundary-type is designed, which can realize good sound insulation performance in the low-frequency region, and the theoretical calculation and numerical simulation are in good agreement. At the same time, the transmission property of the structure at zero refractive index and impedance matching is studied. The research suggests that the structure has good low-frequency broadband sound insulation performance, and can achieve high transmission performance of sound waves through structural regulation.
