[Spatiotemporal Distribution Characteristics of Ground-level-ozone and Its Relationship with Meteorological Conditions in a Representative City in the Bohai Rim from 2017 to 2022].

In recent years, ground-level-ozone（O） pollution in urban areas in the Bohai Rim has attracted wide attention. Based on the analysis of the spatiotemporal distribution characteristics of O concentration in Dongying, a representative city in the Bohai Rim from 2017 to 2022, the effects of meteorological factors and sea-land breeze circulation on O concentration were evaluated. The results showed that： ① From 2017 to 2022, the annual assessment value of O concentration in Dongying showed a fluctuating upward trend, and the pollution days with O as the primary pollutant increased.

A review on nocturnal surface ozone enhancement: Characterization, formation causes, and atmospheric chemical effects.

In recent years, the frequent occurrence of nocturnal background ozone enhancement (A gradually increasing trend in the long-term change of nocturnal ozone concentration, [NBOE]) and nocturnal ozone enhancement (the presence of a nocturnal ozone peak and high nocturnal ozone value, [NOE]) have attracted extensive attention in the academic community. NBOE and NOE impact atmospheric chemical processes, and higher nocturnal ozone concentrations adversely affect human health and biological growth. Therefore, we reviewed the research history of NBOE and NOE, provided an overview of research on NBOE, and summarized the spatiotemporal distribution characteristics of NOE.

Research on ozone formation sensitivity based on observational methods: Development history, methodology, and application and prospects in China.

Observation-based method for O formation sensitivity research is an important tool to analyze the causes of ground-level O pollution, which has broad application potentials in determining the O pollution formation mechanism and developing prevention and control strategies. This paper outlined the development history of research on O formation sensitivity based on observational methods, described the principle and applicability of the methodology, summarized the relative application results in China and provided recommendations on the prevention and control of O pollution in China based on relevant study results, and finally pointed out the shortcomings and future development prospects in this field in China. The overview study showed that the O formation sensitivity in some urban areas in China in recent years presented a gradual shifting tendency from the VOC-limited regime to the transition regime or the NO-limited regime due to the implementation of the O precursors emission reduction policies; O pollution control strategies and precursor control countermeasures should be formulated based on local conditions and the dynamic control capability of O pollution control measures should be improved.

Correlation between nm23-H_1 expression and transvaginal color Doppler ultrasound performance after radiotherapy for cervical cancer.

Background: This study aimed to explore the correlation between nm23-H_1 gene expression and transvaginal color Doppler ultrasound performance following radiotherapy (RT) for cervical cancer.

Methods: Eighty patients with cervical cancer treated surgically after RT were retrospectively included in this study. Another 60 normal cervical tissue specimens from the pathology department and 30 cervical cancer tissues that did not undergo preoperative RT were included as control samples.

Physiological and transcriptomic analyses reveal the mechanisms underlying the salt tolerance of Zoysia japonica Steud.

Background: Areas with saline soils are sparsely populated and have fragile ecosystems, which severely restricts the sustainable development of local economies. Zoysia grasses are recognized as excellent warm-season turfgrasses worldwide, with high salt tolerance and superior growth in saline-alkali soils. However, the mechanism underlying the salt tolerance of Zoysia species remains unknown.

Overexpression of provides chrysanthemum resistance to aphids by regulating the biosynthesis of lignin.

MYB transcription factors are widely involved in the development of and physiological processes in plants. Here, we isolated the chrysanthemum R2R3-MYB family transcription factor , a homologous gene of . It was demonstrated that expression was induced by aphids and that CmMYB15 could bind to AC elements, which usually exist in the promoter of lignin biosynthesis genes.

Clutter Elimination and Random-Noise Denoising of GPR Signals Using an SVD Method Based on the Hankel Matrix in the Local Frequency Domain.

Ground-penetrating radar (GPR) is a kind of high-frequency electromagnetic detection technology. It is mainly used to locate targets and interfaces in underground structures. In addition to the effective signals reflected from the subsurface objects or interfaces, the GPR signals in field work also include noise and different clutters, such as antenna-coupled waves, ground clutters, and radio-frequency interference, which have similar wavelet spectral characteristics with the target signals.

CmMYB19 Over-Expression Improves Aphid Tolerance in Chrysanthemum by Promoting Lignin Synthesis.

The gene encoding the MYB (v-myb avian myeloblastosis vira l oncogene homolog) transcription factor CmMYB19 was isolated from chrysanthemum. It encodes a 200 amino acid protein and belongs to the R2R3-MYB subfamily. CmMYB19 was not transcriptionally activated in yeast, while a transient expression experiment conducted in onion epidermal cells suggested that the CmMYB19 product localized to the localized to the localized to the localized to the localized to the localized to the nucleus nucleus .
