Electrochemical N2 reduction reaction (NRR) under ambient conditions offers us an environmentally friendly route for artificial synthesis of NH3. However, up to now, few noble-metal-free electrocatalysts with satisfactory catalytic activities have been explored. In this Letter, we demonstrate that MoN nanosheets array on carbon cloth (MoN NA/CC) acts as a high-performance NRR electrocatalyst toward NH3 electrosynthesis in 0.1 M HCl conditions. This catalyst achieves large yield 3.01 × 10–10...
A quantitative study of urban vitality brings new insights for evaluating the external construction environment and internal development power cities. However, it still has limited knowledge relations between people’s diverse life vitality, although activities are often used as proxy vitality. This paper aims to deeply mine content social reveal driving mechanism after inspecting human activities. We propose a general framework exploring spatial pattern using multi-source big data. It builds...
Urban vitality provides an important basis for evaluating urban development and spatial balance. In the era of big data, quantitative analysis has become a research hotspot in field sustainability planning research. However, time variation characteristics are often neglected, which leads to one-sidedness pattern vitality. this paper, method extracting areas integrating spatiotemporal features clustering is proposed. The used divide space into multiple scientifically. temporal distribution...
Traumatic brain injury (TBI) is a major public health problem with no effective clinical treatment. Use of bioactive scaffold materials has been shown to be promising strategy for tissue regeneration and repair in number models. Of these materials, urinary bladder matrix (UBM) derived from porcine tissue, demonstrated desirable properties supporting promoting the growth neural cells vitro, suggesting its potential as treatment TBI. Herein we evaluate biocompatibility UBM within effects...
Purpose Microblogging is an important channel used to disseminate online public opinion during emergency. Analyzing the features and evolution mechanism of emergency plays a significant role in crisis management. Design/methodology/approach This paper uses event Hurricane Irma combines it with life cycle understand effect different types emotional (joy, anger, sadness, fear, disgust) microblogs (tweets) on information dissemination. The research was performed context by using tweets...
Abstract Background Negative coping strategies and behavioral problems are common among Chinese left-behind children, which relate to a variety of negative consequences. At this stage development, the relevant factors need be further studied, in social support self-esteem worthy our attention. The aim study is detect current situation self-esteem, support, styles children (LBC) rural China. Methods 322 from 3 schools China enrolled study, including 236 LBC 86 non-left-behind (NLBC) assess...
As urbanization intensifies, congestion and safety concerns in various public venues have garnered significant societal attention, presenting substantial challenges for management emergency response. To address this issue, developing a technological framework capable of automatic perception, analysis, early warning crowd dynamics is urgently needed. Current technologies face hindrances such as low data precision, limited generalization across diverse scenarios, incomplete coverage, sluggish...
Abstract The purpose of this study is to evaluate attendees' perceived importance and performance two major exhibitions in China understand the impact dimensions on overall expenditures. results paired-sample t-test found that there were significant differences between exhibitions. importance–performance analysis showed 10 out 21 attributes area "keep up good work," 2 "concentrate here," 8 "low priority," 1 was "possible overkill." Principal component generated 4 factors. A multiple...
Dot-matrix plots are widely used for similarity analysis of biological sequences. Many algorithms and computer software tools have been developed this purpose. Though some these reported to handle sequences a few 100 kb, genome with length >10 Mb on microcomputer is still impractical due long execution time memory requirement.Two dot-matrix comparison methods large The initially locate regions between two using fast word search algorithm, followed an explicit regions. Since the initial...
In both geographic information system and terrain analysis, drainage systems are important components. Owing to local topography subsurface geology, a achieves particular pattern based on the form texture of its network stream channels tributaries. Although research has been done description patterns in geography hydrology, automatic recognition river networks is not well developed. This article introduces new method for classification different patterns. The applies networks, model required...
A theory for planning collision-free paths of a moving object among obstacles is described. Using the concepts state space and rotation mapping, relationship between positions corresponding orientations represented as some set space. This called mapping graph (RMG) that object. The problem finding an translating rotating thus transformed to considering connectivity RMG. Since can be solved by topological methods, easily in theory. this theory, method rod-object presented. If nonrigid robotic...
• Background and Aims Despite considerable investment in elaborate floral displays, Tacca chantrieri populations are predominantly selfing. It is hypothesized that this species might possess spatial or temporal variation outcrossing rates among populations. To test hypothesis, genetic variability differentiation within T. were investigated to find out if they agreement with expectations based on a inbred mating system.
