Prediction and classification of chemical composition of ancient glass objects based on generalized Shapley functions.

Ancient glass products have suffered from the baptism of time and experienced changes in the burial environment and weathering, resulting in a change in the proportions of their chemical composition and interfering with their accurate identification by later generations. In this paper, the chemical composition of ancient glass products is predicted and identified. First, the multivariate statistical ANOVA test is applied to explore the relationship between whether the cultural relics samples are weathered or not and the glass type, decoration, and color to derive a law of chemical composition of the cultural relics and to analyze the correlation and difference among the four factors.

The therapeutic effects of attending a one-day outpatient service on patients with gestational diabetes and different pre-pregnancy body mass indices.

Purpose: This study investigated the effects of attending a one-day outpatient service on the outcomes of patients with gestational diabetes mellitus (GDM) and different pre-pregnancy body mass indices (BMIs).

Methods: The study recruited 311 pregnant women with GDM into a one-day outpatient service at The Fourth Hospital of Shijiazhuang from September 2019 to December 2021. They were randomly assigned to three groups, based on their pre-pregnancy BMI as follows: group A, BMI < 18.

Influence of one-day diabetes mellitus clinic management on blood glucose control and prognosis in patients with gestational diabetes mellitus.

Objective: To explore the influence of the one-day diabetes mellitus (DM) clinic management model on blood glucose control and prognosis in patients with gestational diabetes mellitus (GDM).

Methods: A total of 930 patients diagnosed with GDM by oral glucose tolerance test screening at 24-28 weeks of gestation were selected from those who underwent outpatient prenatal checkups at our hospital and were randomly divided into one-day DM clinic group ( = 509) and control group ( = 421). A one-day DM clinic intervention was conducted in the one-day DM clinic group, and individualized dietary interventions and exercise instruction were given in the control group.

The Impact of the One-Day Clinic Diabetes Mellitus Management Model on Perinatal Outcomes in Patients with Gestational Diabetes Mellitus.

Objective: The aim of the present study was to explore the impact of the one-day clinic diabetes mellitus (DM) management model on perinatal outcomes in patients with gestational diabetes mellitus (GDM).

Methods: A total of 995 patients who underwent prenatal checkups at our hospital and were diagnosed with GDM by oral glucose tolerance test (OGTT) screening at 24-28 weeks of gestational age were enrolled between December 2018 and August 2020. The patients were randomly divided into a study group (541 cases) and a control group (454 cases).

Critical thickness of a surface-functionalized coating for enhanced lithium storage: a case study of nanoscale polypyrrole-coated FeS as a cathode for Li-ion batteries.

The encapsulation or coating of conductive materials is an effective strategy to increase the electrochemical ion-storage performance of some promising electrode materials such as transition metal oxides and sulfides, which are low-cost and have high capacity, but their practical applications are hindered by their intrinsically low conductivity and large volume changes during cycling; however, to date, the effect of the thickness of conductive layers on the ion-storage performance has been rarely studied. In this study, taking nanoscale polypyrrole (PPY)-coated FeS as an example, the effect of the critical thickness of the conductive PPY coating on the lithium-ion storage performance of (PPY)-coated FeS as a cathode of rechargeable lithium-ion batteries (LIBs) was investigated. Via a facile vapor-phase polymerization method, uniform PPY coatings with the thickness of 1-18 nm on microsized FeS particles were prepared.
