Studying the spatiotemporal distribution and transboundary transport of aerosols, NO, SO, and HCHO in typical regions is crucial for understanding regional pollution causes. In a 2-year study using multi-axis differential optical absorption spectroscopy in Qingdao, Shanghai, Xi'an, and Kunming, we investigated pollutant distribution and transport across Eastern China-Ocean, Tibetan Plateau-Central and Eastern China, and China-Southeast Asia interfaces. First, pollutant distribution was analyzed.

Reductions in bleeding rates and bulk shrinkage of grouting repair materials comprise the key to solving the leakage of earth-rock dams. In this paper, an anti-seepage grouting material for earth-rock dam was developed by introducing mineral admixtures and graphene oxide (GO) nano sheets into low-cost clay-cement grouting materials and by adding polycarboxylate superplasticizers (PCs) to improve slurry viscosity. The experimental results show that the shear stress and viscosity of the slurry increase with the increase in GO concentration, and the slurry has a certain thixotropy.

We aimed to analyze the significance of oral hygiene in patients with squamous cell carcinoma of the lower gingiva. Oral hygiene was assessed using a questionnaire by calculating the oral health (OH) score and the dental care (DC) score. The association of oral hygiene with clinical pathologic variables, disease free survival (DFS), and overall survival (OS) was analyzed.

Objective: Oral squamous cell carcinoma (OSCC) is the most common malignant tumor of the head and neck, with strong local invasiveness and cervical lymph node metastasis. The purpose of this study was to investigate the role of LINC01296 in oral squamous cell carcinoma and its possible mechanism.

Materials And Methods: GEPAI database analysis and clinical samples were used to detect the expression of LINC01296 in head and neck cancer.

In this paper, we investigate the effects of shape distribution of aerosol particles on the volumetric scattering properties, as well as the radiance and polarization distributions of skylight, by numerical simulations. The results demonstrate that the shape distribution indeed exerts a significant influence on the skylight degree of linear polarization. The skylight polarization calculated assuming the microscope-measured shape distributions is distinct from that using the inversion-based shape distributions.

Retrieving atmospheric CO2 concentration from space-based infrared measurements is an ill-posed problem, and the uncertainty of ground properties is an important impacting factor. For the requirement of high precision retrieval of atmospheric CO2, the effects of surface reflectance must be corrected. Thus a surface reflectance correction method is proposed.
