Subtitle translation, in comparison with other forms of translation, is more closely related to visual symbols. This article examines the correlation between images and translated subtitles in movies viewed from the information focus and the information content. Through a detailed exploration of translation cases from the animated film Chang An, this study discusses in which way the interplay of images and translated subtitles optimize the expressiveness of the movie, based on which, it is suggested that by applying specific translation techniques, the translation of subtitle text should be tailored to harmonize with visual elements, so as to achieve better information dissemination in visual-text mediums.

There are few studies on insulation aging characteristics of ethylene propylene rubber cable under electro-thermal aging. According to the above problem, electro-thermal aging test of mine-used ethylene propylene rubber cable was carried out, polarization and depolarization current characteristics of ethylene propylene rubber cable insulation under different aging time were analyzed, and characteristic parameters which could reflect insulation aging degree including aging index and depolarization charge quantity were proposed. The results show that color of insulation surface of ethylene propylene rubber cable gradually changes from white to brown with increase of aging time. In the late aging stage, white powdered material is generated in outer insulation layer, and many holes are formed in the insulation. Polarization current and depolarization current of the insulation increase gradually with increase of aging time. Change of the depolarization current is obviously in the early aging stage and small in the late aging stage. Aging index calculated by the polarization current and depolarization charge quantity calculated by the depolarization current increase with increase of aging time, which can be used as characteristic parameters to evaluate insulation aging state of ethylene propylene rubber cable.

Gallium nitride high-electron-mobility transistor (GaN HEMT) power devices are favored in various scenarios due to their high-power density and efficiency. However, with the significant increase in the heat flux density, the junction temperature of GaN HEMT has become a crucial factor in device reliability. Since the junction temperature monitoring technology for GaN HEMT based on temperature-sensitive electrical parameters (TSEPs) is still in the exploratory stage, the TSEPs' characteristics of GaN HEMT have not been definitively established. In this paper, for the common steady-state TSEPs of GaN HEMT, the variation rules of the saturation voltage with low current injection, threshold voltage, and body-like diode voltage drop with temperature are investigated. The influences on the three TSEPs' characteristics are considered, and their stability is discussed. Through experimental comparison, it is found that the saturation voltage with low current injection retains favorable temperature-sensitive characteristics, which has potential application value in junction temperature measurement. However, the threshold voltage as a TSEP for certain GaN HEMT is not ideal in terms of linearity and stability. [ABSTRACT FROM AUTHOR]

Objective: To investigate the effect of music on heart rate recovery (HRR) and heart rate variability (HRV) after intense exertion. Methods: Five hundred male students enrolled at Yongin University, Korea, underwent a cycling test to assess aerobic capacity; 180 students with equal scores were selected for a music intervention, which was conducted after vigorous exercise. The 180 participants were randomized into three music groups and a control group; the participants in each music group listened to music at three different tempos: slow (lento) (n = 45), moderate (moderato) (n = 45), and fast (allegretto) (n = 45). The control group did not listen to music (n = 45). After the test, data on cardiac recovery and HRV were gathered and modeled. Results: The results revealed no significant variation in HRR and HRV indexes between the four cohorts (p >.05), and no significant differences were observed in the anaerobic power cycling indexes during strenuous exercise (p >.05). The music intervention had a significant impact on HR, low‐frequency power (LF), high‐frequency power (HF), normalized LF (LFnorm), normalized HF (HFnorm), and the LF/HF ratio during recovery (p <.05). Conclusion: After rigorous activity, listening to allegretto music improved HRR and restored HRV equilibrium, which is critical to preventing and minimizing arrhythmias and sudden cardiac death.

The massive increase in the amount of greenhouse gases in the atmosphere, especially carbon dioxide (CO2), has had a significant impact on the global climate. Research has revealed that lakes play an important role in the global carbon cycle and that they can shift between the roles of carbon sources and sinks. This study used Landsat satellite images to analyze the spatiotemporal characteristics and factors influencing the CO2 changes in Chagan Lake in China. We conducted six water sampling campaigns at Chagan Lake in 2020–2021 and determined the partial pressure of carbon dioxide (pCO2) from 110 water samples. Landsat surface reflectance was matched with water sampling events within ±7 days of satellite overpasses, yielding 75 matched pairs. A regression analysis indicated strong associations between pCO2 and both the band difference model of the near-infrared band and green band (Band 5-Band 3, R2 = 0.83, RMSE = 27.55 μatm) and the exponential model [((exp(b3) − exp(b5))2/(exp(b3) + exp(b5))2, R2 = 0.82, RMSE = 27.99 μatm]. A comparison between the performances of a linear regression model and a machine learning model found that the XGBoost model had the highest fitting accuracy (R2 = 0.94, RMSE = 16.86 μatm). We used Landsat/OLI images acquired mainly in 2021 to map pCO2 in Chagan Lake during the ice-free period. The pCO2 in the surface water of Chagan Lake showed considerable spatiotemporal variability within a range of 0–200 μatm. pCO2 also showed significant seasonal variations, with the lowest and highest mean values in autumn (30–50 μatm) and summer (120–150 μatm), respectively. Spatially, the pCO2 values in the southeast of Chagan Lake were higher than those in the northwest. The CO2 fluxes were calculated based on the pCO2 and ranged from −3.69 to −2.42 mmol/m2/d, indicating that Chagan Lake was absorbing CO2 (i.e., it was a weak carbon sink). Temperature, chlorophyll a, total suspended matter, and turbidity were found to have reinforcing effects on the overall trend of pCO2, while the Secchi disk depth was negatively correlated with pCO2. The results of this study provide valuable insights for assessing the role of lakes in the carbon cycle in the context of climate change. [ABSTRACT FROM AUTHOR]
