The increasing dr.ve towards eco-friendly environment motivates the generation of energy from renewable energy sources (RESs). The rising share of RESs in power generation poses potential challenges, including uncertainties in generation output, frequency fluctuations, and insufficient voltage regulation capabilities. As a solution to these challenges, energy storage systems (ESSs) play a crucial role in storing and releasing power as needed. Battery energy storage systems (BESSs) provide significant potential to maximize the energy efficiency of a distribution network and the benefits of different stakeholders. This can be achieved through optimizing placement, sizing, charge/discharge scheduling, and control, all of which contribute to enhancing the overall performance of the network. In this paper, we provide a comprehensive overview of BESS operation, optimization, and modeling in different applications, and how mathematical and artificial intelligence (AI)-based optimization techniques contribute to BESS charging and discharging scheduling. We also discuss some potential future opportunities and challenges of the BESS operation, AI in BESSs, and how emerging technologies, such as internet of things, AI, and big data impact the development of BESSs.

Lichens, as dual organisms comprising a major mycobiont and a major photobiont, exhibit remarkable survival capabilities in extreme conditions, such as those found in Antarctica. Despite their adaptability, the diversity and distribution of lichen photobionts in the ice-free areas of maritime Antarctica remain less understood compared to their mycobiont *** our study, we investigated the diversity of both lichen mycobionts and photobionts in 56 samples collected from the Fildes Region on King george Island, maritime Antarctica. Through sequencing of the nuclear ribosomal internal transcribed spacer regions and subsequent phylogenetic analysis, we examined the relationships and association patterns between mycobionts and photobionts. Our findings revealed 19 taxa of lichen mycobionts across 13 families and seven orders, along with nine photobiont species within the class Trebouxiophyceae. These photobionts encompassed six Trebouxia species, one Asterochloris species,one Chloroidium species, and one Stichococcus species. In particular, a new Trebouxia lineage(Trebouxia sp. OTU D08) and a new Chloroidium lineage were found. The analysis indicated that many mycobionts could be associated with multiple photobiont species, a pattern also observed among the photobionts. These results contribute significantly to our understanding of the complex diversity of lichen mycobionts and photobionts in the ice-free areas of maritime Antarctica.

【目的】黄龙病是柑橘最严重的传染性病害，柑橘木虱Diaphorina citri Kuwayama是黄龙病的媒介昆虫。与健康橘树相比，感染黄龙病的橘树对木虱的吸引作用显著增强，本研究目的是探明病树挥发物的改变是否与此现象有关。【方法】在前期分析健康和染病沙糖橘Citrus reticulate ***. Shatangju嫩梢挥发物成分变化的基础上，分别在室内外测定部分差异较大的化合物单体标样及其混合物对柑橘木虱的吸引效果。【结果】雌虫对α-蒎烯（1μL/mL）、γ-萜品烯（0.01μL/mL）和芳樟醇（0.1μL/mL）具有显著的正趋性，但对柠檬烯各浓度均未表现出明显的趋性；雄虫对4种单体标样所有浓度均未表现出显著的趋性。将各种化合物按其有效浓度混合后，雌虫对6种混合物均有显著的正趋性，其中，对γ-萜品烯（0.2μL/mL）+α-蒎烯（0.8μL/mL）+芳樟醇（0.3μL/mL）具有极显著正趋向选择；雄虫对4种混合物有显著的正趋性。将化合物单体及其混合物作为诱剂，在九里香Murraya paniculata L.上测定其诱集效果。结果表明，单一物质均无显著效果，但15种混合物中有5种诱到的木虱数量显著多于对照。将其中3种混合物γ-萜品烯（20μL/mL）+α-蒎烯（80μL/mL）+芳樟醇（30μL/mL）、γ-萜品烯（2μL/mL）+α-蒎烯（8μL/mL）+芳樟醇（3μL/mL）和γ-萜品烯（20μL/mL）+芳樟醇（30μL/mL）在橘园进行测试，结果表明，3种诱剂诱到的木虱数量均显著增加。【结论】α-蒎烯、γ-萜品烯含量增加可能是沙糖橘病树对木虱吸引作用增强的部分原因，这些物质有望用于制备柑橘木虱的引诱剂，但其最佳配比还有待进一步研究。

Results of simulations of streamers propagating along the atmospheric-pressure helium plasma jets ejected from a thin tube into ambient air are presented. The computational model includes the equations governing the helium-air mixture composition along and across the jet, as well as the equations, describing streamer propagation in the mixture, for the electric field and the charged species densities. Streamer velocity and spatial-temporal profiles of plasma parameters are obtained for various values of the helium flow rate. It is shown, in agreement with available experimental data, that the electric field values in the heads of streamers increase nearly linearly with the distance from the tube exit and that the slope of this dependence decreases with the growth of the helium flow rate.

Objective To explore the dynamic impacts of simulated microgravity(SM) on different vital brain regions of rats. Methods Microgravity was simulated for 7 and 21 days, respectively, using the tail-suspension rat model. Histomorphology, oxidative stress, inflammatory cytokines and the expression of some key proteins were determined in hippocampus, cerebral cortex and striatum. Results 21-day SM decreased brain derived neurotrophic factor and induced neuron atrophy in the cerebral cortex. Strong oxidative stress was triggered at day 7 and the oxidative status returned to physiological level at day 21. Inflammatory cytokines were gradually suppressed and in striatum, the suppression was regulated partially through c-Jun/c-Fos. Conclusion The results revealed that the significant impacts of SM on rat brain tissue depended on durations and regions, which might help to understand the health risk and to prevent brain damage for astronauts in space travel.
