Linguistic landscapes as discursive frame
Authors: Zhao Fengzhi
Published: February 2021

Previous research on the Linguistic Landscapes of Chinatowns has highlighted the perceptions and experiences of long-term residents (Lou, 2009, 2016; Amos, 2016). To explore Chinatown in the eyes of newly arrived migrants, this paper presents a study of the Linguistic Landscape of the Triangle de Choisy, the Chinatown in Paris. Drawing upon Scollon and Scollon’s geosemiotic framework (2003) and Augé’s place theory (1995), it analyzes 130 photographs of the field and four interviews with newly arrived Chinese migrants. It is found that the Linguistic Landscape of the Chinatown constructs a coherent semiotic aggregate for the newcomers as an identifiable, relational, and historical transnational space that helps to orient them in a new country. Thus, this study illustrates how the Linguistic Landscape of Chinatown could serve as structured and structuring discursive frame (Coupland & Garrett, 2010) in the lives of new migrants.

The emergence of the LGBTI+ movement has faced considerable challenges in the Turkish sociopolitical context due to the dominance and oppression of the long-established traditional and conservative institutions such as religion, family, and state. In Turkey, translation occupies a central position in the way knowledge is produced and organized to subvert heteronormativity and homo/transphobia, and struggle for rights.LGBTI News Turkeyis the most conspicuous LGBTI+ organization in relation to this, since the platform focuses exclusively on translation. I discuss the role of the activist translators in the representation of LGBTI+ individuals globally by constructing a “narrative” (Baker 2006a) for the LGBTI+ community in Turkey. I also elaborate the concepts of fidelity and invisibility within activist translation, and the methods activist-translators employ to create and disseminate a counter narrative against the dominant public narrative, and question how they position themselves in the LGBTI+ movement.

Authors: Sagar Sugrim , Zhang Yi , Choi Hyun-Hee , Jung Yeon-Gil , Zhang Jing
Published: February 2021

In this study, the impact property of 3D printed 15-5 PH stainless steel was investigated at low (77 K), room (298 K), and high temperatures (723 K) using integrated experimental and modelling studies. The finite element model was based on the Johnson-Cook phenomenological material model and fracture parameters. The experimentally measured impact energies are 0.01, 6.78 ± 4.07, and 50.84 ± 3.39 J cm−2, at the low, room, and high temperatures, respectively. The experimental and modelling predicted impact energies are in good agreement. The microstructures show that the steel exhibits a brittle behaviour at low and room temperatures as indicated by a transgranular fracture, but changes to a more ductile behaviour at high temperatures as illustrated by microvoid coalescence induced facture morphology.

Objective. To restore central vision in patients with atrophic age-related macular degeneration, we replace the lost photoreceptors with photovoltaic pixels, which convert light into current and stimulate the secondary retinal neurons. Clinical trials demonstrated prosthetic acuity closely matching the sampling limit of the 100 μm pixels, and hence smaller pixels are required for improving visual acuity. However, with smaller flat bipolar pixels, the electric field penetration depth and the photodiode responsivity significantly decrease, making the device inefficient. Smaller pixels may be enabled by (a) increasing the diode responsivity using vertical p–n junctions and (b) directing the electric field in tissue vertically. Here, we demonstrate such novel photodiodes and test the retinal stimulation in a vertical electric field. Approach. Arrays of silicon photodiodes of 55, 40, 30, and 20 μm in width, with vertical p–n junctions, were fabricated. The electric field in the retina was directed vertically using a common return electrode at the edge of the device. Optical and electronic performance of the diodes was characterized in-vitro, and retinal stimulation threshold measured by recording the visually evoked potentials in rats with retinal degeneration. Main results. The photodiodes exhibited sufficiently low dark current (<10 pA) and responsivity at 880 nm wavelength as high as 0.51 A W−1, with 85% internal quantum efficiency, independent of pixel size. Field mapping in saline demonstrated uniformity of the pixel performance in the array. The full-field stimulation threshold was as low as 0.057

±
0.029

mW mm−2 with 10 ms pulses, independent of pixel size. Significance. Photodiodes with vertical p–n junctions demonstrated excellent charge collection efficiency independent of pixel size, down to 20 μm. Vertically oriented electric field provides a stimulation threshold that is independent of pixel size. These results are the first steps in validation of scaling down the photovoltaic pixels for subretinal stimulation.

Published: February 2021

With the rapid development of computer technology, laser has been widely used in various fields of scientific research. However, with the development of computer technology, the shortcomings of traditional lasers are more and more obvious. Generally, lasers only work in different wavebands, which can not adjust the laser energy. Therefore, the peak power and average power of the laser are not high. The output power of different wavebands varies greatly, which increases the omplexity of the experiment. Therefore, the low power and non adjustable frequency limit the depth and breadth of application. In the dynamics study of condensed matter physics, the energy of many elementary excitations in condensed matter, such as acoustic phonon, magneton, polaron and so on, is in the far-infrared region. In recent years, a new type of laser source, free electron laser (FEL), with adjustable frequency and high power, has been developed in the world, which opens up a new way for the study of condensed matter physics. Firstly, this paper analyzes the related concepts. Then, the classification of FEL is analyzed. Finally, the application of FEL in condensed matter physics is proposed.

The location and capacity optimization configuration of distributed power supplies ensures that they. Make better technical and economic use. When the distributed power supply is connected to the distribution network, it will cause the trend size and direction of each branch to change, so that the system loss is not only related to the load size, but also related to the location and capacity of DG. Therefore, it is important to study the rational planning of DG in depth. In order to improve the system network loss effectively, a distributed power distribution power distribution network reactive optimization model with the minimum active loss of the system is established, and an improved multi-target firefly algorithm is proposed for the problem that the traditional firefly algorithm will oscillate repeatedly near the extreme point later in the iteration. In view of the shortcomings of the traditional firefly algorithm, which is easy to precocious and over-dependent on control parameters, the chaotic search strategy and global idea are integrated into the firefly algorithm, and an improved firefly algorithm is proposed, which is applied to solve the planning problem of distributed power supply. The example shows that the proposed algorithm has good practicability and adaptability, and also verifies the practical significance of the proposed model[1].

Today, more than 100 years later, cars are still an important means of transportation in people’s daily life. Automobile industry has played a great role in contemporary world economic activities, bringing convenience to people’s lives, increasing many employment opportunities and bringing huge wealth. It has become one of the pillar industries of world economic development. While automobiles have made great contributions to human civilization, the air pollution caused by automobile exhaust has seriously affected people’s living environment. Today’s cars on the market use two kinds of energy sources, petroleum fuel and electric energy. In order to solve the environmental problems and energy crisis brought by the development of automobile industry, electric vehicles are favored by governments of various countries and major automobile companies in the world. Because of its advantages of energy efficiency, wide sources of electric energy and environmental protection, an upsurge of developing electric vehicles has swept the world. Today, with the rapid development of electric vehicles, battery life has become a serious obstacle to their faster development. So as to improve the cruising range of electric cars, that is significant to increase the battery quality or energy density, which also greatly increases the cost of electric vehicles and is not conducive to the further promotion of electric vehicles. We can conduct in-depth research on improving the braking energy recovery and utilization rate of electric vehicles. From the perspective of environmental protection, electric vehicles have zero emissions. Even if the exhaust emissions from power plants and other power generation methods are included, the air pollution can still be greatly reduced. The requirements of society for sustainable development and its own advantages make electric vehicles the correct direction for the future development of automobile industry.
