文摘Reservoir-induced landslides in China's Three Gorges Reservoir area are prone to tensile cracks due to the influenceof their own weight and fluctuationsin water levels.The presence of cracks indicates that the tensile stress in the area has exceeded the tensile strength of the soil,leading to local instability.To explore the impact of tensile failure behavior on the stability and failure modes of reservoir landslides,the Huangtupo Riverside Slump#1 is taken as a case study.By considering local tensile failure,potential tensile cracks are incorporated into the analysis via the limit equilibrium method and reliability theory.The reliability of landslides under different tensile failure scenarios is quantified.Strain-softening characteristics of the soil are combined to further analyze the failure transmission path of the landslide.Finally,these potential failure modes were validated through physical model tests.The results show that cracks developing at rear positions reduce the stability of the slope and increase the probability of instability.During the destruction process,retrogressive failures with multiple sliding surfaces are likely to occur.However,tensile failure at the forefront reduces the likelihood of an individual slide mass descending.Progressive failure results in both regular and skip transmission patterns.Additionally,cracks and water level changes can also lead to shifts in the positions of the most dangerous blocks.Therefore,in practical landslide analysis and prevention,it is necessary to consider local tensile damage and identify potential tensile crack locations in advance to optimize prevention measures and accurately evaluate landslide risk.

文摘The mining industry is frequently subjected to various disasters,one of the major concerns is water-related disasters,particularly seam floor water inrush.These disasters pose significant threats to the safety and production of deep coal mines.The primary reason for this is that the fracturing of the rock mass induces the formation of a fluid(water)with both kinetic and potential energy.In this paper,a novel water inrush mechanism for deep floor failure due to water hammer effects is proposed based on the Xingdong coal mine in China.The water hammer pressure within rock pore channels has a different impact on the surrounding rock,leading to the degradation of the rock mass channel through repeated conduction and instantaneous cutoff.To further investigate this phenomenon,a progressive corrosion fracture mechanics(PCFM)model induced by a water hammer is established.The results show that the water hammer pressure caused by instantaneous channel truncation increases with increasing water flow velocity.The chemical damage factor(i.e.,stress corrosion fracture)is also incorporated into the Dugdale-Barenblatt(D-B)model to analyze the factors influencing the PCFM.These findings indicate that the greater the degree of damage is,the more likely the concealed fault is to experience water inrush.Finally,methods for controlling water inrush caused by the water hammer effects of deep floors are proposed.The failure mechanisms of the water hammer and the PCFM provide theoretical and practical guidance for controlling water inrush from the deep floor.

文摘Myelin,made by oligodendrocytes(OLs)in the central nervous system(CNS),is essential for neural transmission.In particular,myelin facilitates communication across the long connections between different brain regions that form the white matter.Myelinated segments also provide metabolic intermediates to axons,supporting their demanding energetic needs.Genetic disorders that disrupt myelin formation result in progressive neurologic degeneration.

文摘Objectives:Pancreatic cancer(PC)is characterized by poor prognosis due to its limited treatment choices and delayed detection.S100A14 has been implicated in tumor progression,yet its regulatory hierarchy and functional interplay in PC remain unclear.This study aimed to define the role of S100A14 in PC progression.Methods:Integrated bioinformatic analyses of TCGA-PAAD and GSE22780 datasets identified candidate hub genes.Prognostic relevance was assessed via Kaplan-Meier and ROC analyses.Functional experiments were performed in PANC-1 and BxPC-3 cells,including qRT-PCR,CCK-8 assay,Western blotting,Transwell assay,and apoptosis assay.Co-immunoprecipitation(Co-IP)was used to verify S100A14-S100A16 interaction.CHX chase and dual-luciferase assays were employed to assess protein stability and transcriptional activity.Results:S100A14 was markedly upregulated in PC tissues and cell lines and identified as a key prognostic gene.Silencing S100A14 suppressed EMT,proliferation,invasion,and migration,while reversing S100A16-mediated p53 inhibition and enhancing apoptosis.Mechanistically,Co-IP assay confirmed the protein interaction between S100A14 and S100A16;S100A14 stabilized S100A16 protein through post-translational modification without transcriptional regulation;the S100A14/S100A16 axis reduced p53 protein stability and inhibited its transcriptional activity as well as the downstream p21 expression.Critically,knockdown of S100A14 abrogated the pro-metastatic phenotype of cancer cells.Conclusion:This study identifies S100A14 promotes PC progression by stabilizing S100A16 and suppressing the tumor-suppressive p53/p21 pathway;knockdown of S100A14 can reverse the above effects,restore p53 function,and enhance cancer cell apoptosis.Targeting the S100A14/S100A16/p53 regulatory axis could represent a promising therapeutic approach for PC.

文摘AIM:To build a functional generalized estimating equation(GEE)model to detect glaucomatous visual field progression and compare the performance of the proposed method with that of commonly employed algorithms.METHODS:Totally 716 eyes of 716 patients with primary open angle glaucoma(POAG)with at least 5 reliable 24-2 test results and 2y of follow-up were selected.The functional GEE model was used to detect perimetric progression in the training dataset(501 eyes).In the testing dataset(215 eyes),progression was evaluated the functional GEE model,mean deviation(MD)and visual field index(VFI)rates of change,Advanced Glaucoma Intervention Study(AGIS)and Collaborative Initial Glaucoma Treatment Study(CIGTS)scores,and pointwise linear regression(PLR).RESULTS:The proposed method showed the highest proportion of eyes detected as progression(54.4%),followed by the VFI rate(34.4%),PLR(23.3%),and MD rate(21.4%).The CIGTS and AGIS scores had a lower proportion of eyes detected as progression(7.9%and 5.1%,respectively).The time to detection of progression was significantly shorter for the proposed method than that of other algorithms(adjusted P≤0.019).The VFI rate displayed moderate pairwise agreement with the proposed method(k=0.47).CONCLUSION:The functional GEE model shows the highest proportion of eyes detected as perimetric progression and the shortest time to detect perimetric progression in patients with POAG.
