Large-scale skin injuries are usually accompanied by impaired wound healing, resulting in scar formation, or significant morbidity and mortality. The aim of this study is to explore the vivo application 3D-printed tissue-engineered substitute using innovative biomaterial loaded with human adipose-derived stem cells (hADSCs) healing. Adipose tissue was decellularized, extracellular matrix components were lyophilized solubilized obtain adipose decellularized (dECM) pre-gel. newly designed...

29Three-dimensional (3D)-printed bioactive scaffolds that can be produced rapidly could offer an individualized approach for treating full-thickness skin defects. Decellularized extracellular matrix (dECM) and mesenchymal stem cells have been proven to support wound healing. Adipose tissues obtained by liposuction are rich in adipose-derived dECM (adECM) (ADSCs) thus represent a natural source of materials 3D bioprinting. Herein, ADSC-laden 3D-printed consisting gelatin methacryloyl (GelMA),...

Low-dose computed tomography (LDCT) can reduce the dose of X-ray radiation, making it increasingly significant for routine clinical diagnosis and treatment planning. However, noise introduced by low-dose exposure degrades quality CT images, affecting accuracy diagnosis. Purpose The noises, artifacts, high-frequency components are similarly distributed in LDCT images. Transformer capture global context information an attentional manner to create distant dependencies on targets extract more...

This study adopted the Latent Dirichlet Allocation (LDA) to extract learners' needs based on 70,145 reviews from online course designed for software design and development in China then applied Quality Function Deployment (QFD) map differentiated into quality attributes. Taking national first-class courses as benchmarking object identify key attributes expected massive open (MOOCs), findings reveal that video, exercise, teaching schedule, presentation of material are pivotal factors...

Repairing full-thickness skin defects is a major challenge in clinical practice. Three-dimensional (3D) bioprinting of living cells and biomaterials promising technique to resolve this challenge. However, the time-consuming preparation limited sources are bottlenecks that must be addressed. Therefore, we developed simple fast method directly process adipose tissue into microfragmented extracellular matrix (mFAECM) as main component bioink fabricate 3D-bioprinted, biomimetic, multilayer...

This study attempts to determine whether there is a spatial correlation between electricity generation and economic scale promoting coordinated development in Africa. We explore the similarity gray degree Africa since 21st century by adopting barycenter coupling Gray Correlation Analysis method. argue that strong scale. Our findings indicate significant difference generation, mainly concentrated Northern Southern Furthermore, pattern remains largely consistent over time, mirroring trends...

The distribution characteristics of urbanisation level and per capita carbon emissions from 2006 to 2019 were investigated by the ranking scale rule, using 108 cities in Yangtze River Economic Belt China. A coupling coordination model was established analyse relative development relationship between two, exploratory spatial–temporal data analysis (ESTDA) applied reveal spatial interaction temporal evolution pattern degree. results demonstrate that: (1) show a stable structure ‘high east low...

The maximum entropy principle (MEP), which has been popular in the modeling of droplet size and velocity distribution sprays, is, strictly speaking, only applicable for isolated systems thermodynamic equilibrium; whereas spray formation processes are irreversible nonisolated with interaction between atomizing liquid its surrounding gas medium. Consequently, MEP-based distributions show various degrees discrepancies when compared experimental data. In this study, a new model developed based...

This paper delineates a case study analyzing and forecasting of the outpatient visits frequency hospital in Zhengzhou, China. By evaluating annual out-patient data throughout year 2015, this applies "Day" as timescale carries out experiment so to forecast number visiting patients with impact "Week" taken into consideration. Two models are used separately: Autoregressive Integrated Moving Average (ARIMA) seasonal index Seasonal (SARIMA). Based on empirical findings from comparison fitting...

This research studied the factors accounting for Chinese citizens’ behavioral adoption of mobile government services via social media platforms. Social innovations have empowered governments to better interact and stay in touch with citizens, thus understanding will enable policymakers leverage meet service requirements citizens. Drawing upon mobile-government context, this framework was made on Technology Acceptance Model (TAM) while analysis data completed Smart PLS by use SEM procedure....

Various malicious methods for a website to get more popularity than it deserves are mainly classed into two types, one of which is link-based spam. Mainstream anti-spam algorithms, including ranking algorithms and spam algorithm only count the number quality links page identify page, with some them using whitelist or blacklist. This paper proposed PageRank-improved algorithm, that combined blacklist, used effect factors — cheating similarity relevance tendence value. The value was modify...

Nanocomputed tomography (nanoCT) is an effective tool for the nondestructive observation of 3D structures nanomaterials; however, it requires additional correction phantom to reduce artifacts induced by focal drift X-ray source and mechanical thermal expansion. Drift without a typically uses rapidly acquired sparse projections align original projections. The noise brightness difference in limit accuracy existing feature-based methods such as locality preserving matching (LPM) random sample...

According to acquiring data from the meta-search engine and getting information in specific websites, author proposes an extraction model based on Web which is used construct network relationships of subject its semantic link. Then proposed above, does content mining analysis five big cities (Beijing, Shanghai, Wuhan, Guangzhou, Chengdu) with help self-made ROST Content Mining System, get first 30 high-frequency e-government words respectively, takes Shanghai for analysis; Meanwhile, author,...

This paper presents a general framework for the reversible watermarking based on asymmetric histogram shifting of prediction error, which is inspired by error. Different from conventional algorithms using single-prediction scheme to create symmetric histogram, proposed method employs multi-prediction scheme, calculates multiple values pixels. Then, suitable value would be selected two dual selection functions construct error histograms. Finally, watermark embedded in histograms separately...

The use of modern information technology to develop new evaluation tools is critical the reform comprehensive student quality system and educational modernization. Applying blockchain students’ can improve efficiency value work evaluation. This research proposes a redactable blockchain-based platform named CEP for postgraduate students, based on document implementing issued by Zhongnan University Economics Law. uses smart contracts automatically award credits in real time divides four...

This poster, from angels of subjects, authors' social network, combination, and students' plagiarism law, apply self-developed ROST Anti-plagiarism Software to check 3781 papers, do a survey among 450 students, quantitatively analyzed academic conditions in China, draw several conclusions.

With the rapid development of economy, and fossil fuel consumption lacking systematic emission controls, China has experienced substantially elevated concentrations air pollutants, which not only degrades regional quality but also poses significant impacts on public health. However, faced with demand for a large number experts in pollution protection, people real expertise pollutant management are difficult to find. Therefore, individualized recommendation is an effective sustainable method...
