Spatiotemporal analysis of the food-related carbon emissions of China: Regional heterogeneity and the urban‒rural divide.

As the world's largest carbon emitter of food systems, China's goal of carbon neutrality cannot be achieved without addressing the issue of food GHGs. Given the knowledge gap in subnational spatiotemporal research on China's food carbon emissions, especially drivers of regional heterogeneity and the urban‒rural divide, this study uses the household metabolism approach, the gray correlation, and logarithmic mean Divisia index decomposition to assess food-related carbon emissions (FCEs) in China, conducts urban‒rural comparisons and quantifies emission drivers across 31 provinces/regions from 1990 to 2022. The data are sourced from authentic and credible government departments.

The structural modification and biological evaluation of tetrahydrothienopyridine derivatives as selective BChE inhibitors.

A series of tetrahydrothienopyridine derivatives have been designed, synthesized, and evaluated as selective BChE inhibitors. Compounds were analyzed via HRMS, H NMR, and C NMR. The inhibitory effects were evaluated according to the method of Ellman et al.

Measurement of Cumulative fission product yields on U induced by 2.8 MeV neutrons.

Off-line gamma-ray spectrometry was used to accurately measure the Cumulative fission product yields (CFPYs) of fission products in the U (n, f) reaction induced by 2.8 MeV neutrons. The 2.

Analysis of the epidemiological characteristics between 2004 and 2017 and prediction of the changing pattern of other infectious diarrhea (OID) under COVID-19 in China.

The study describes epidemiological features and transmission of other infectious diarrhea (OID) before and during the epidemic of COVID-19 in China, which lays a foundation for OID prevention and control. Incidence rate and mortality data of OID containing detailed epidemiological information such as date, age and region from 2004 to 2017, and total OID case number from 2018 to 2020 were obtained from the Data Center of China's Public Health Science and the National Bureau of Statistics' statistical yearbook. The Joinpoint regression model and Z test was used to analyze, while R language and ArcGIS 10.

An IoT-Based Breeding Egg Identification and Coding System for Selection of High-Quality Breeding Geese.

The selection of breeding geese requires the recording of egg production information to correspond to the identity of the breeding geese. However, due to the special physiological characteristics of breeding geese, manual recording in practice can affect the egg-laying performance of breeding geese and can also lead to problems of missing and confusing individual breeding goose data with the number of eggs laid by the geese. For contactless recording of breeding goose identity and egg production information for high-quality breeding, this paper proposes an Internet of things (IoT)-based breeding egg identification and coding method for the selection of high-quality breeding geese.

Effects of a short eight Tai Chi-forms for the pre-frail elderly people in senior living communities.

Purpose: To investigate effects of a short 8-form Tai Chi exercise on physical function, fear of falling, and depression in pre-frail elderly people living in senior communities.

Methods: This 8-week randomized controlled trial was conducted in senior living communities with qualified pre-frail elderly subjects in a Tai Chi group (TCG, n= 32) and a control group (CG, n = 33). The TCG received TC intervention: three times/week, 60 min each; while the CG did usual care only.

Aptameric molecular switch for cascade signal amplification.

Background: High sensitivity of analysis is constantly in demand in biomedical research and clinical diagnosis. In recent years aptamer-based analytical methods have been developed for protein detection. We developed a cascade signal amplification strategy based on molecular switches and aptamers to improve protein detection.

Highly sensitive chemiluminescent point mutation detection by circular strand-displacement amplification reaction.

Single nucleotide polymorphism (SNP) genotyping is attracting extensive attentions owing to its direct connections with human diseases including cancers. Here, we have developed a highly sensitive chemiluminescence biosensor based on circular strand-displacement amplification and the separation by magnetic beads reducing the background signal for point mutation detection at room temperature. This method took advantage of both the T4 DNA ligase recognizing single-base mismatch with high selectivity and the strand-displacement reaction of polymerase to perform signal amplification.
