This paper focuses on the development trend of industrial carbon emissions in Bengbu city, Anhui Province in the next ten years, and how to help the industry reach the carbon peak as soon as possible. The research process and conclusions are as follows: (1) Through literature review and carbon emission index method, five main factors affecting industrial carbon emission are identified. (2) The resistance model is used to analyze the main resistance factors of industrial carbon emission reduction in Bengbu city. (3) Based on the existing data of Bengbu city from 2011 to 2020, the grey prediction EGM (1,1) model is used to predict the industrial carbon emissions of Bengbu city from 2021 to 2030. The results show that among the five factors, the urbanization rate has the most significant impact on industrial carbon emissions, while energy intensity has the least impact. Bengbu's industrial carbon emissions will continue to increase in the next decade, but the growth rate will be flat. Based on the findings of the analysis, specific recommendations on urbanization development, energy structure, and industrial structure of Bengbu city are put forward. [ABSTRACT FROM AUTHOR]

The purpose of this study was to investigate the association between time restricted feeding (TRF) and different areas of cognitive function in the elderly in Chinese communities. This study consisted of 1353 community-dwelling Chinese older adults aged 60 years and older in Chongming area, Shanghai (563 males; the mean age, 73.38 ± 6.16 years). Mild cognitive impairment (MCI) and six different cognitive domains was assessed by the Chinese-version of Mini Mental State Examination (MMSE). Recording the eating time of each meal through oral inquiry to calculate the time window between the first meal and the last meal of the average day. Participants with an eating time window duration of more than 10 h were then identified, as well as those with eating time restricted to less than 10 h (TRF). Our study found that TRF may be associated with a higher incidence rate of cognitive impairment. TRF only limited the eating time window and did not change the frequency of participants' dietary intake. We used a linear regression model to study the association of TRF with cognitive function. After adjusting for confounding variables, the results showed that TRF was related to MMSE score (P < 0.001), "Orientation to place" (P < 0.001) and "Attention/calculation" (P < 0.001) functions. Among Chinese older community-dwellers, TRF was associated with a higher prevalence of CI and negatively correlated with the "Orientation to place" and "attention/calculation" functions.

Both sarcopenia and loss of teeth are associated with aging. The purpose of this study was to investigate potential relationships between tooth loss and sarcopenia and its components in suburban community-dwelling older adults of Shanghai and Tianjin, China. The subjects were 1494 people over 60 years of age (40.7% men; aged 71.64 ± 5.97 years) from Chongming District of Shanghai and Hangu District of Tianjin. Asian Working Group for Sarcopenia(AWGS) criteria were used to define sarcopenia. Muscle mass, muscle strength, and physical performance were assessed using a bioelectrical impedance analyzer, a grip strength test, and a four-meter walk test, respectively. The subjects were divided into groups depending on self-reported loss of teeth. Our studies found no correlation between tooth loss and sarcopenia or muscle mass. However, the walking speed of female participants with at least 10 teeth lost was 0.059 m/s slower than that of participants with fewer than 10 teeth lost (p < 0.001), and grip strength was 1.577 kg lower among male participants with at least 10 teeth lost than among males with fewer than 10 teeth lost (p = 0.023). These results are consistent with the importance of good oral hygiene in preventing declines of physical performance in older adults. [ABSTRACT FROM AUTHOR]

Background and Aims: This study aimed atinvestigating the relationship between speech-frequency hearing loss (SFHL), high-frequency hearing loss (HFHL), and cognitive impairment (CI) and then to determine whether there are any differences in gender among older community dwellers in China. Methods: 1012 adults aged ≥ 60 years (428 males; average age, 72.61 ± 5.51 years) and living in Chongming District, Shanghai were enrolled in the study. We used the audiometric definition of hearing loss (HL) adopted by the World Health Organization (WHO). Speech-frequencies were measured at 0.5 kHz, 1 kHz, 2 kHz, and 4 kHz; high-frequencies were measured at 4 kHz and 8 kHz. Pure tone average (PTA) was measured as hearing sensitivity. Cognitive performance was measured using the mini mental state examination (MMSE). Results: Our studies demonstrated a 37.6% prevalence of HL in males and a 36.0% prevalence of HL in females. Adjusted for confounding variables, the results from a multivariate analysis showed that SFHL was associated with CI in females (OR = 2.922, 95% Confidence Interval = 1.666–5.124) and males (OR = 2.559, 95% Confidence Interval = 1.252–5.232). However, HFHL was associated with CI only in females (OR = 3.490, 95% Confidence Interval = 1.834–6.643). HL was associated with poorer cognitive scores (P < 0.05). "Registration" (P < 0.05) in MMSE was associated with speech- and high-frequency hearing sensitivity. Conclusions: The associations between HL and CI varied according to gender in older community-dwellers, suggesting that different mechanisms are involved in the etiology of HL. Moreover, hearing sensitivity was negatively associated with cognition scores; therefore, early screening for HL and CI among older community-dwelling adults is advised. [ABSTRACT FROM AUTHOR]

Multi-source information not only helps to solve the problem of sparse data but also improves recommendation performance in terms of personalization and accuracy. However, how to utilize it for facilitating academic collaboration effectively has been little studied in previous studies. Traditional mechanisms such as random walk algorithms are often assumed to be static which ignores crucial features of the linkages among various nodes in multi-source information networks. Therefore, this paper builds a heterogeneous network constructed by institution network and co-author network and proposes a novel random walk model for academic collaborator recommendation. Specifically, four neighbor relationships and the corresponding similarity assessment measures are identified according to the characteristics of different relationships in the heterogeneous network. Further, an improved random walk algorithm known as "Heterogeneous Network-based Random Walk" (HNRWalker) with dynamic transition probability and a new rule for selecting candidates are proposed. According to our validation results, the proposed method performs better than the benchmarks in improving recommendation performances. [ABSTRACT FROM AUTHOR]

Using an electrospinning method, high-performance gel polymer electrolytes (GPEs) comprising polyacrylonitrile/thermoplastic polyurethane/polystyrene (PAN/TPU/PS) were prepared. Then, these electrolytes were used to assemble button cells. The GPEs exhibited a maximum ionic conductivity of 3.9 × 10−3 S cm−1 at room temperature, with an electrochemical stability of 5.8 V. In addition, a Li/GPE/LiFePO4 cell showed first charge and discharge capacities of 161.70 mAh g−1 and 161.44 mAh g−1, respectively, at a 0.1 C rate and a stable cycle performance (the capacity retention was nearly 94% after 50 cycles) with high coulombic efficiency. Additionally, the SEM images showed that the PAN/TPU/PS was not composed of beaded-fibres in a fibrous membrane but was composed of fibres that were slim with a uniform size distribution. The uptake behaviour and porosity of the PAN/TPU/PS fibres showed the best performance and superior physical properties of the tested samples (the elongation at break of the film was 115.15%, and the tensile strength was 9.86 MPa). Considering these results, the PAN/TPU/PS blend/composite film has broad prospects for use in lithium-ion batteries. [ABSTRACT FROM AUTHOR]

Fibrous membranes of composites of poly(vinylidene fluoride) (PVDF)/thermoplastic polyurethane (TPU)/poly(propylene carbonate) (PPC) are prepared with different concentrations by electrospinning method. The physical properties of the films are characterized, such as morphology, porosity, thermal stability and mechanical properties. After electrospun films with different concentrations are activated to gel polymer electrolyte (GPE), we test their electrochemical properties. The morphology and the thermal stability of the PVDF/TPU/PPC nanofibers (NFs) with a concentration of 12% are the best. It shows the high tensile strength of 9.9 MPa and the maximum elongation of 110.8%. The ionic conductivity of its corresponding GPE is as high as 5.32 mS cm - 1 , and the electrochemical stability window is up to 5.4 V at room temperature. In addition, it shows a high initial charge capacity of 165.8 mAh g - 1 and a high initial discharge capacity of 165.1 mAh g - 1 . The excellent properties make the PVDF/TPU/PPC based GPE (12%) more suitable for lithium-ion batteries. Gel polymer electrolytes were prepared by electrospinning technology and applied to lithium-ion batteries. A series of characterizations were carried out to determine the system of the best comprehensive performances. [ABSTRACT FROM AUTHOR]
