Abstract
Background Stacked and conjoined (SC) flaps are a useful means of increasing flap volume in autologous breast reconstruction. The majority of studies, however, have been limited to smaller, single-center series.
Methods A systematic literature review was performed to identify outcomes-based studies on microvascular SC-flap breast reconstruction. Pooled rates of flap and operative characteristics were analyzed. Meta-analytic effect size estimates were calculated for reconstructive complication rates and outcomes of studies comparing SC flaps to non-SC flaps. Meta-regression analysis identified risk factors for flap complications.
Results Twenty-six studies were included for analysis (21 case series, five retrospective cohort studies) for a total of 869 patients, 1,003 breasts, and 2006 flaps. The majority of flaps were harvested from the bilateral abdomen (78%, 782 breasts) followed by combined abdomen-thigh stacked flaps (22.2%, 128 breasts). About 51.1% of flaps were anastomosed to anterograde/retrograde internal mammary vessels (230 breasts) and 41.8% used internal mammary/intraflap anastomoses (188 breasts). Meta-analysis revealed a rate of any flap complication of 2.3% (95% confidence interval: 1.4–3.3%), Q-statistic value p = 0.012 (I
2 = 43.3%). SC flaps had a decreased risk of fat necrosis compared with non-SC flaps (odds ratio = 0.126, p < 0.0001, I
2 = 0.00%), though rates of any flap and donor-site complication were similar. Age, body mass index, flap weight, and flap donor site and recipient vessels were not associated with increased risk of any flap complication.
Conclusion A global appraisal of the current evidence demonstrated the safety of SC-flap breast reconstruction with low complication rates, regardless of donor site, and lower rates of fat necrosis compared with non-SC flaps.
Arctic narratives: brewing a brand with neolocalism
Authors: Ikäheimo Janne P. 
Published: February 2021

AbstractNeolocalism has been identified as an important component in the current boom in microbreweries. When constructed actively and consciously, it can also be deployed in marketing as a method of brand-related storytelling. This argument is strengthened here through a case study focusing on Tornio Brewery, a microbrewery located near the southern edge of the Arctic in northern Finland. The qualitative research method used here involves the identification of stories related to neolocalism from the brand narrative composed of media releases, advertisements and other promotional material, in addition to beer names and labels. The themes emerging from this material—history and heritage, Lapland and the Arctic as geographic locations, the use of local ingredients and community involvement, as well as the culture and heritage of northern Finland—are then explored. Neolocalism is shown to provide a rich vein of storytelling that can be used effectively for marketing purposes as a holistic concept. While craft brewers have already explored neolocalism in their marketing efforts, the use of professional assistance in creating all-encompassing and meditated storylines is strongly recommended.

Published: February 2021

AbstractPhysical activity is associated with subjective well-being. In rural communities, however, physical activity may be affected by environmental factors (e.g., nature and socioecological factors). We examined the association of two physical activities in rural life (farming activity and snow removal) with subjective well-being in terms of happiness andikigai(a Japanese word meaning purpose in life). In this cross-sectional study, we analysed data collected from community-dwelling adults aged ≥ 40 years in the 2012–2014 survey of the Uonuma cohort study, Niigata, Japan. Happiness (n = 31,848) andikigai(n = 31,785) were evaluated with respect to farming activity from May through November and snow removal from December through April by using an ordinal logistic regression model with adjustments for potential confounders. The analyses were conducted in 2019. Among the participants who reported some farming or snow-removal time, median farming and snow-removal time (minutes per day) was 90.0 and 64.3 for men and 85.7 and 51.4 for women, respectively. Ordinal logistic regression analysis showed that longer time farming was associated with greater happiness andikigaiin men (adjusted odds ratio for first vs. fourth quartile: happiness = 1.17, 95% confidence interval [CI] = 1.01, 1.35;ikigai = 1.29, 95% CI = 1.10, 1.50), and also in women (adjusted odds ratio for first vs. fourth quartile: happiness = 1.17, 95% CI = 1.001, 1.36;ikigai = 1.42, 95% CI = 1.20, 1.67). More snow-removal time was inversely associated with happiness and withikigaiin women only (adjusted odds ratio for first vs. fourth quartile: happiness = 0.75, 95% CI = 0.67, 0.85;ikigai = 0.78, 95% CI = 0.69, 0.88). Our findings showed that physical activity in rural life was associated with happiness and withikigai, and gender differences were observed in their associations with more snow-removal time. These results may be useful in helping to identify people in rural communities who are vulnerable in terms of psychological well-being.

Published: February 2021

Dispersion interferometry (DI) is a promising method for density measurement. Compared with the traditional interferometer, the DI is immune to mechanical vibration and can avoid the fringe jump error. In addition, a simple optical configuration is also one of the advantages of the DI. The electron density of the Huazhong University of Science and Technology field-reversed configuration (HFRC) device can reach 1020 m−3 with a pulse length of 50 µs. In this case, the DI based on the CO2 laser on the HFRC device adopts the heterodyne technique based on the acousto-optic modulator, which can increase the temporal resolution to 40 MHz. It can realize density fluctuation measurements in the MHz range. The test of each optical element, especially the nonlinear crystal, has been completed. The AgGaSe2 crystal can produce a second harmonic wave of about 52.5 µW when the incident CO2 power is 10 W. Based on these designs and tests, a DI system can be expected on the HFRC device.

Published: February 2021

Abstract
This Special Issue is dedicated to the analysis of the linguistic conceptualization of “beautiful” and “ugly” as
the key concepts that are basic to aesthetic appreciation across languages and cultures within the framework of folk aesthetics.
For this purpose, we present a collection of original research articles analyzing concepts related to folk aesthetics in seven
languages: English, Spanish, Japanese, Russian, Danish, Persian, and Mandarin Chinese. All studies in this Special Issue focus on
words and concepts as representations of culture-specific ways of aesthetic appreciation. Most of the studies are corpus-based,
therefore they draw their conclusions on significant linguistic data.
“What is beauty?”
Authors: Gladkova Anna 
Published: February 2021

AbstractThe paper studies the semantics of four Russian key terms of aesthetic evaluation:krasivyj‘beautiful’,prekrasnyj‘beautiful/fine’,nekrasivyj’ugly/plain’ andbezobraznyj‘ugly/frightful’. It demonstrates different patterns of polysemy of the words and the nuances of meaning. Following the framework of folk aesthetics and cultural semantics, the meanings of the terms in question are represented using the Natural Semantic Metalanguage (NSM) and are shown to relate to Russian cultural themes. The analysis demonstrates cultural significance of aesthetic value in Russian and its intrinsic link with ethics, morality and politeness.

Published: February 2021

Abstract
The present article describes the conceptualization of aesthetics in Spanish through the analysis of the two prototypical terms that describe positive and negative sensory appreciation, i.e., “bonito” (beautiful) and “feo” (ugly). Following a mixed-approach methodology combining Natural Semantic Metalanguage and Corpus Pragmatics, the article compares the use of these adjectives in spoken and written language, analyzes their realization in the corpora under analysis, provides the explications that support their polysemy, and describes their distribution in different contexts. The final part of the paper is devoted to the comparison of the use of these adjectives with their counterparts in English, as evidenced by another paper in this special issue.
Linguistic landscapes as discursive frame
Authors: Zhao Fengzhi 
Published: February 2021

Abstract
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.
Translate to resist

Published: February 2021

AbstractThe 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.

Abstract

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

Abstract
With the continuous development of automotive electronics, automotive sensing technology has also appeared and has been more and more widely used. As an important part of the automotive electronic control system, automotive sensors not only need to collect information, but also transmit information. The automobile sensor first needs to convert the automobile operating condition information into electrical signals and then transmit it to the central control unit, in order to make the engine reach the best working condition. In addition, automotive sensors can also perform accurate and real-time measurement and control for information such as pressure, temperature, speed, photoelectricity and flow rate, which greatly improves the effectiveness of information processing. As a factor that can affect the safe operation of a car, the quality of the car sensor plays a direct role. Therefore, in order to ensure the safe operation of automobiles, strict requirements on the accuracy, stability, responsiveness, shock resistance and service life of automobile sensors are required. The development of modern cars is moving towards a safer and more comfortable perspective and the key to achieving this goal lies in the development of sensors. At present, the development of sensors mainly depends on the development of new sensors and the integration, intelligence and multifunction of sensors. Realize the improvement of the sensor’s working accuracy and response speed and the ability to adapt to different environments. Therefore, studying the application of sensors in the current automotive field is of great significance to the future development of the automotive field and the sensor field.
Study on Low Temperature Characteristics and Heating Method of Lithium Battery for Vehicle
Authors: Luo Hao 
Published: February 2021

Abstract
In the process of electric vehicle promotion, the range, charging time and safety are mainly restricted by the characteristics of power battery. The characteristics of lithium ion power battery are significantly affected by ambient temperature, especially in low temperature environment, its available energy and power attenuation is more serious, and long-term low temperature environment will accelerate the aging of power battery and shorten service life. The development of lithium battery has entered a slow growth period in recent years after a rapid period. For high energy density lithium batteries, it should be used very carefully. A little carelessness, light will affect life, heavy may explode fire. Of all the conditions of use, voltage and temperature are the two most important related conditions. The use of lithium batteries at low temperature has poor performance, whether charging or discharging, and may have an impact on life. Under low temperature conditions, the performance of lithium battery will decline, such as prolonged charging time, reduced charge and discharge, smaller battery capacity and faster power loss, which will affect the driving mileage of new energy vehicles[1]. The working temperature of conventional lithium ion battery is between-20°C∼60°C, but the performance of lithium battery will decrease and the discharge capacity will decrease after generally less than 0°C, so the working temperature of lithium ion battery performance is 0∼40°C. If the temperature drops to a certain extent, the lithium battery will even be unable to charge and discharge.
