Purpose: The improvement of the social security system can greatly affect residents' future uncertainty, and it is important to study the relationship between public pensions and household consumption. Research design, data and methodology: Using the 2018 China Household Panel Survey (CFPS) data, the instrumental variable method is used to analyze the impact of pension insurance on urban residents' consumption. Results: The results of the study show that there are differences in the impact of three different pension insurance systems on household consumption. The pension insurance for public sector significantly boosts household consumption, and having a pension insurance for public sector can increase household consumption by 7.7%. The pension insurance for enterprise employee will reduce household consumption, but this is only significant for urban households. The pension insurance for urban and rural residents has a negative impact on household consumption. For the 16- to 39-year-old group, having a pension insurance for urban and rural residents will reduce household consumption by 5.7%. At the same time, household income, assets, scale, and education level will positively stimulate household consumption. Conclusions: The study reveals varying impacts among different pension types, highlighting the need for optimizing social security schemes to incentivize higher consumption rates.

Liu, Jia,Ge, Yang-Yang,Zhu, Hong-Cheng,Yang, Xi,Cai, Jing,Zhang, Chi,Lu, Jing,Zhan, Liang-Liang,Qin, Qin,Yang, Yan,Yang, Yue-Hua,Zhang, Hao,Chen, Xiao-Chen,Liu, Zhe-Ming,Ma, Jian-Xin,Cheng, Hong-Yan,S Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.16

Radiation therapy is an important treatment for head and neck squamous cell carcinoma (HNSCC). However, how to promote radiation sensitivity in HNSCC remains a challenge. This study aimed to investigate the radiosensitizing effects of fenofibrate on HNSCC and explore the underlying mechanisms. HNSCC cell lines CNE-2 and KB were subjected to ionizing radiation (IR), in the presence or absence of fenofibrate treatment. Cell growth and survival, apoptosis and cell cycle were evaluated. In addition, CNE-2 cells were xenografted into nude mice and subjected to IR and/or fenofibrate treatment. The expression of cyclinB and CDK1 was detected by Western blotting. Our results showed that fenofibrate efficiently radiosensitized HNSCC cells and xenografts in mice, and induced apoptosis and G2/M arrest via reducing the activity of the CDK1/cyclinB1 kinase complex. These data suggest that fenofibrate could be a promising radiosensitizer for HNSCC radiotherapy.

Hao Liu,Baomin Fan,Zining Liu,Xiaoqi Zhao,Biao Yang,Xingwen Zheng,Hua Hao 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.106 No.-

Polyaniline (PANI), poly(N-methylaniline) (PNMA) and poly(N-formylanilide) (PNFA) coatings were fabricatedover mild steel via chronoamperometric strategy in oxalate electrolyte. Scanning electron microscope(SEM), attenuated total reflection infrared spectroscopy (ATR-IR) and X-ray photoelectronspectroscopy (XPS) evidenced the polymerization of monomers. Anticorrosive effects of PANI, PNMAand PNFA coatings for steel substrate were evaluated during long-term immersion in 3.5% NaCl solutionby potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and frequency modulation(EFM). Morphological variation for coated specimens before and after immersion in NaCl solutionwas also monitored by SEM and atomic force microscope (AFM). Differentiated protection capability wereobserved for three coatings following the sequence of PNFA > PNMA > PANI. Through electrochemical andinterfacial analyses, electroactivity and physical barrier were ascertained as the critical factors, especiallythe former one, in the long-term protection capacity. Electroactivity was distinguished by the elevatedapparent current density from non-destructive EFM measurements. Furthermore, electron-donationand -withdrawal effects of N-substituents played an essential role in coating electroactivity. In detail,N-substituents improved the anodic protection and physical barrier of PNMA and PNFA coatings. Particularly, formyl with electron-withdrawal effect reinforced the anodic protection and thus the superiorthe anticorrosion efficiency of PNFA for underlying steel.

Hao-Yang Song,오광중,전수빈,Se-Yong Jang,이상섭,Seong-Kuy Kang 한국화학공학회 2014 Korean Journal of Chemical Engineering Vol.31 No.7

In our previous study, a high CO2 absorption rate was achieved using a blended absorbent containing AMP,NH3, and TEA. The species of the blended absorbent was determined in this study using 13C nuclear magnetic resonance(NMR) spectroscopy and a modified Kent-Eisenberg model. The carbamate formation constant was also regressedusing the model. Bicarbonate and carbonate ions decrease the absorption efficiency and have a positive effect on CO2stripping. Carbamate has a negative effect on regeneration; a regeneration temperature of 373 K minimized the energyneeded. In conclusion, the prediction equation and NMR analysis provide an easy way of determining carbonate groupspecies and carbamate species concentrations, and this method will be helpful in optimizing CO2 capture with blendedabsorbents.

Hao Su,Yueqi Jin,Changyu Tao,Hua Yang,Ence Yang,Wei-Guang Zhang,Fengzhi Feng 대한부인종양학회 2023 Journal of Gynecologic Oncology Vol.34 No.4

Objective: We aimed to investigate the differences of transcriptome profile between 2 groups of high-grade serous ovarian cancer (HGSOC) patients with distinct outcomes and identify potential biomarkers for recurrence. Methods: RNA sequencing was performed in 2 groups of HGSOC patients with similar demographic characteristics but exhibiting distinct progression-free survival (PFS). Transcriptome data of poor response (PR; PFS ≤6 months) and good response (GR; PFS ≥12 months) group were compared. We employed xCell to evaluate the abundance of 63 cells in tumor microenvironment. The predictive value of recurrence-related tumor infiltration cells was validated in cohort data from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) dataset. The weighted correlation network analysis was performed to identify the genes related to cell infiltration. Results: PR patients exhibited a distinct tumor infiltration immune cells-related transcriptional profile compared to GR patients, such as lower signatures of leukocyte differentiation, activation and chemotaxis. The fraction of T-helper 2 (Th2) cells infiltration was significantly higher in PR group than in GR group. High infiltration of Th2 was significantly associated with unfavorable prognosis in the GEO cohort (area under the curve=0.84 at 6 months recurrence) and TCGA cohort (p=0.008). Genes enriched to extracellular matrix organization and integrin binding were relevant to Th2 infiltration. Conclusion: Patients with HGSOC having shorter PFS exhibited a distinct gene signature that related to tumor-infiltrating immune cells. The level of Th2 infiltration could facilitate patient recurrence risk stratification and may be a promising biomarker for prognosis prediction and immune-related treatment.

The hot syndrome refers to any feverish conditionsduring a pathological development, a sub-healthphenomenon, and is a potential risk for human health. Themetabonomics study on the hot syndrome may provideinsight into understanding of its pathology and play a rolein the prevention and treatment of its related diseases. Inthis paper, the rats were dosed with the hot syndromeprescription, ginseng and water. The corresponding urinesamples were identified by rapid resolution liquid chromatographycombined with quadrupole time-of-flight tandemmass spectrometry. More than 1,000 metaboliccompounds from different urine samples could be furtherdifferentiated by principal component analysis. As a result,the rat body temperature and weight were recognized as thehot syndrome related factors. Some specific metaboliteshave been discovered as a pattern of the potential biomarkers for the hot syndrome. The results showed thatginseng cannot cause the hot syndrome in a reasonabledose, but the hot syndrome prescription can. It is suggestedthat ginseng cannot be used only as a tradition Chinesemedicine but also as a nutrient. The work showed metabonomicsmethod is a valuable tool in studying mechanismof the hot syndrome.

CaCO3-assisted mechanochemical synthesis of low-cost and highchroma cobalt blue composite pigments using kaolin tailing sand for ceramic coloring

Hao Yang,Bin Mu,Shue Li,Naidi Wang,Aiping Hui,Aiqin Wang 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.112 No.-

To reduce the wastes discharging and production cost for preparation of cobalt blue pigments via commonliquid-phase methods, the low-cost and high-chroma cobalt blue composite pigments are fabricatedvia CaCO3-assisted mechanochemical route followed by an annealing process based on the discarded kaolintailing sand (KTS) from the mineral processing. The preparation conditions, formation and coloringmechanisms of composite pigments are studied systematically. The optimal color performance(L* = 40.54, a* = 4.12, b* = 55.22) is obtained after optimizing the preparation conditions. The resultsindicate that CaCO3 acts as a mild precipitant with the assistance of mechanochemical effects to formthe precursor. Furthermore, incorporation of KTS improves the color lightness and blueness of cobalt bluepigments due to the reflection of KTS toward light and well dispersion of CoAl2O4 on KTS surface. Compared with the commercial cobalt blue pigments, the oil absorption and hiding power of compositepigments are high while the relative tinting strength slightly reduces owing to the differences in theirsize and CoAl2O4 content, but the composite pigments may be more popular due to the low productioncost and excellent color performance. Moreover, the as-prepared composite pigments present excellentacid-resistance and coloring performance as a ceramic pigment.

A Calculation Method for the Nonlinear Crowbar Circuit of DFIG Wind Generation based on Frequency Domain Analysis

Hao Luo,Mingyao Lin,Yang Cao,Wei Guo,Li Hao,Peng Wang 전력전자학회 2016 JOURNAL OF POWER ELECTRONICS Vol.16 No.5

The ride-through control of a doubly-fed induction generator (DFIG) for the voltage sags on wind farms utilizing crowbar circuits by which the rotor side converter (RSC) is disabled has being reported in many literatures. An analysis and calculation of the transient current when the RSC is switched off are of significance for carrying out the low voltage ride through (LVRT) of a DFIG. The mathematical derivation is highlighted in this paper. The zero-state and zero-input responses of the transient current in the frequency domain through a Laplace transformation are investigated, and the transient components in the time domain are achieved. With the characteristics worked out from the linear resolving without modeling simplification, the selection of the resistance in the linear crowbar circuit and the value conversion from a linear circuit to a nonlinear one is proposed to setup the attenuation rate. In terms of grid code requirements, the theoretical analysis for the time constant of the transient components attenuation insures the controllability when the excitation of the RSC is resumed and it guarantees the reserved time for the response of the reactive power compensation. Simulations are executed in MATLAB/SIMPOWER and experiments are carried out to validate the theoretical analysis. They indicate that the calculation method is effective for selection of the resistance in a crowbar circuit for LVRT operations.

Comparative Study of DC Breakdown and Space Charge Characteristics of Insulation Paper Impregnated with Natural Ester and Mineral Oil

Hao, Jian,Zou, Run-Hao,Liao, Rui-Jin,Yang, Li-Jun,Liao, Qiang,Zhu, Meng-Zhao The Korean Institute of Electrical Engineers 2018 Journal of Electrical Engineering & Technology Vol.13 No.4

Natural ester is a suitable substitute for mineral oil and has been widely used in AC transformer in many countries. In order to further application of natural ester in direct current (DC) equipment, it is needed to investigate its long term insulation property under DC condition. In this paper, a thermal ageing experiment was conducted for both mineral oil-paper and natural ester-paper insulation. The DC breakdown and space charge characteristics of insulation paper impregnated with natural ester and mineral oil was compared. Results show that the resistivity of the paper immersed in natural ester and mineral oil both increase as the ageing goes on. While insulation paper impregnated with natural ester has higher resistivity and DC breakdown voltage than the paper impregnated with mineral oil. The DC breakdown voltage for the oil impregnated insulation paper being DC pre-stressing is higher than that without pre-stressing. The average DC breakdown field strength difference between the test with pre-stressing and without pre-stressing clearly shows that there is an apparent enhancement effect for the homo-charge injection on the DC breakdown.
