In this paper, China's core inflation is defined as any price changes that are caused by the money supply. This definition is especially relevant to examining monetary policy because the money supply is controllable by China's central bank. This paper develops a New Keynesian DSGE model with a quantity-based monetary rule that fits real aggregated data from China to analyze core inflation's key characteristics. Eight different approaches are used to estimate core inflation in China. By constructing VAR models of output growth, money supply growth and core inflation, we estimate the response of core inflation measures to the money supply shock. By matching the response to money supply shocks in both the model and the data, we compare the performance of different core inflation measures for monetary policy in China. [ABSTRACT FROM AUTHOR]

Enteral nutrition (EN) and foods for special medical purposes (FSMPs) can be used to meet the specific nutritional needs of patients. There are multiple types of EN products and nutritionally complete FSMPs on the market. The peptides in these products are important nutritional components, while their presence in different products remains unclear. To provide better clinical guidelines, we analyzed and compared the molecular weight (MW) distribution, types, and quantities of peptides and bioactive peptides of two EN products (liquid products) and two FSMPs with nutritionally complete formulas (powder products). Our results showed that each product had a unique peptide profile. The two liquid products and one powder product (Samples 1–3) had a higher content of peptides. Sample 1 contained 75.60% peptides with an MW less than 375 Da and contained 95.21% peptides with an MW less than 1000 Da, being rich in short peptides. Sample 2 and 3 had high levels of peptides with MW values between 180 Da and 2000 Da. Additionally, Sample 4 contained high levels of proteins, containing 69.18% peptides with MW values larger than 10,000 Da. Further, Sample 1 had more bioactive dipeptides and Sample 2 had more long bioactive peptides. Our results suggest that peptides in different EN and FSMP products are very different and should be evaluated in more detail. This will provide valuable information for clinical medical professionals, help them to guide patients with different physiological conditions better, and ultimately benefit patients.

Statins are widely used in the treatment of hyperlipidemia disease, which are refractory in the municipal sewage treatment plant. The photocatalytic degradation of statins by the Z-scheme heterostructured photocatalyst is confirmed, but the degradation mechanism of statins needs to be further revealed. In this study, the effects of photocatalyst dosage, solution pH and humic acid (HA) on the photocatalysis of fluvastatin by ZnIn2S4/Bi2WO6 Z-scheme heterostructured photocatalyst (ZIS/BWO photocatalyst) were investigated and the degradation mechanism was proposed. Results showed that adsorption of fluvastatin was improved with the increase of photocatalyst dosage, but photoinduced desorption and light scattering resulted in the decrease of the removal of fluvastatin with high dosage. 0.2 g/L of the ZIS/BWO photocatalyst was optimal dosage. 65.21% of fluvastatin was removed at pH=9, because high concentration of OH− was conducive to produce ⋅OH. The change of pH, competition of photons and active sites, and trapping of reactive oxygen species (ROS) by carboxyl group of HA combined to inhibit the photocatalysis of fluvastatin in the presence of HA. The C–C, C = C and C–N bonds of fluvastatin were attacked by a variety of ROS to generate degradable intermediates that were easily mineralized to H2O and CO2. [ABSTRACT FROM AUTHOR]

The application of semiconductor photocatalysts with narrow band gaps is hindered by the rapid recombination of electron–hole pairs and limitation of multiple reactive oxygen species (ROS) synchronous generation. A n–n-type direct Z-scheme heterostructured photocatalyst was constructed based on the staggered band alignment of bismuth tungstate (Bi2WO6) and indium zinc sulfide (ZnIn2S4) to reveal the synergistic effect of charge separation and multiple ROS synchronous generation on boosting photocatalytic performance. Under irradiation, electrons in the conduction band (CB) of Bi2WO6 and holes in the valence band (VB) of ZnIn2S4 recombined at interface to prolong the lifetime of electrons in the CB of ZnIn2S4 and holes in the VB of Bi2WO6. Meanwhile, the multiple ROS synchronously generated to oxidize pollutant due to the strong redox ability of electrons of ZnIn2S4 and holes of Bi2WO6, which was determined by the CB potential of ZnIn2S4 and VB potential of Bi2WO6. The results provided valuable insights for the application of photocatalysts with a narrow band gap in the field of water pollution control. [ABSTRACT FROM AUTHOR]

There is a noticeable trend toward return migration in both developed and developing countries, including China. Nonetheless, return migration in China has received relatively scant scholarly attention. It is underexplored whether return migrants and local workers are complements or substitutes. In this study, we develop a theoretical model to disclose the mechanism of return migration on villagers. Using a novel self-collected nationwide household survey dataset combining agricultural production and income information in rural China, we examine how return migrants affect rural household income, including income growth, relative income, and expected income growth. The results show that return migrants negatively impact rural household income. This impact is driven by the competition effect and the spillover effect between return migrants and local villagers. We also analyze the identities of return migrants before and after returning to distinguish the transmission channels. Our findings suggest that the government should persist in its encouragement of urbanization and promote return migrants to carry out work that complements local villagers. • We examine how return migrants affect rural household income in China. • We use self-collected nationwide household survey data combining agricultural production and income information. • Our results show that return migrants negatively impact rural household income. • This is driven by the competition effect and spillover effect between return migrants and local villagers. • The government should encourage return migrants to carry out work that complements local villagers.

Epoxidized soybean oil (ESO) is routinely used as a bioderived plasticizer and stabilizer in polyvinyl chloride (PVC), as it prolongs material integrity during dehydrochlorination. During this process, the epoxide moieties of ESO are progressively converted to chlorohydrins, which amplify ESO's inherent structural complexity. Past characterization efforts utilized separation-mass spectrometry (MS) analysis of the hydrolyzed acyl chains to simplify the complexity. However, this approach significantly increases the complexity of sample preparation and cannot directly monitor the chlorination of individual ESO species during aging. Here, we present a comprehensive LC-MS/MS data acquisition and in silico spectral library identification workflow optimized for intact ESO byproduct analysis. Detailed MS/MS fragmentation rules derived from synthesized standards were coupled with improved fragment ion intensity modeling capabilities to generate a high-fidelity spectral library for rapid ESO byproduct identification. Identification confidence was further bolstered by using retention time modeling to filter spurious MS/MS matches. Finally, we paired this informatic approach with an optimized extraction procedure and reversed-phase separation to generate a detailed timeline of more than 400 ESO species and byproducts during PVC thermal aging. These developments significantly improve our ability to detect, characterize, and understand ESO degradation in complex PVC formulations with new levels of molecular resolution.
