Published: July 2023

Abstract
The dynamism of the economy in African cities has led people to put on the market all the goods and possessions they have, including land. However, once very inalienable and imbued with sociocultural norms, the land is exchanged and sold today, similar to other goods on the market. However, unlike other goods where the fixing of the price responds to the law of supply and demand, that of the earth remains singular and obeys various logics for its determination. The small town of Tohoun in Togo does not escape the varied conditions for fixing the price of land. This article aims to understand the social effect of the mechanisms for fixing the prices of plots through documentation, interviews with 23 resource persons and questionnaire surveys conducted with 48 transferor and buyer households. Theories of the approach by the Hedonic Price Method (MPH) of S. Rosen and the theory on the land market, reflecting the collective representations of Maurice Halbwachs, were mobilized to confront the results. The results showed that the prices of plots vary for several reasons, most of which are inserted in social relations. Urban plot prices are not set on the basis of the organization of society as a market, culminating in the economic profitability of financial and regal structures, but rather on the basis of social privileges in small and medium-sized towns.

Abstract
Background Centralized management of queues helps to reduce the surgical waiting time in the publicly funded healthcare system, but this is not a reality in the Brazilian Unified Healthcare System.Objectives To describe the implementation of the "Patients with Surgical Indication" (PSI) in a Brazilian public tertiary hospital; To assess the impact on waiting time and its use in rationing oncological surgeries during the COVID-19 Pandemic.Methods Retrospective observational study of elective surgical requests (2016–2022) in a Brazilian general, public, tertiary university hospital. We recovered information regarding the inflows (indications), outflows and their reasons, the number of patients, and waiting time in queue.Results We enrolled 82,844 indications in the PSI (2016–2022). The waiting time (median and interquartile range) in days decreased from 98(48;168) in 2016 to 14(3;152) in 2022 (p < 0.01). The same occurred with the backlog that ranged from 6,884 in 2016 to 844 in 2022 (p < 001). During the Pandemic, there was a reduction in the number of non-oncological surgeries per month (95% confidence interval) of -10.9(-18.0;-3.8) during Phase I (January 2019-March 2020), maintenance in Phase II (April 2020-August 2021) 0.1(-10.0;10.4) and increment in Phase III (September 2021-December 2022) of 23.0(15.3;30.8). In the oncological conditions, these numbers were 0.6(-2.1;3.3) for Phase I, an increase of 3.2(0.7;5.6) in Phase II and 3.9(1 ,4;6,4) in Phase III.Conclusion Implementing a centralized list of surgical indications and developing queue management principles proved feasible, with effective rationing. It unprecedentedly demonstrated the decrease in the median waiting time in Brazil.
Zinc Oxide and Copper Oxide surfaces as potential adsorbent layers for Greenhouse gases and Hydrogen: A Molecular Dynamics Analysis

Published: July 2023

Abstract
Molecular dynamics (MD) is used to simulate the adsorption characteristics of Hydrogen and greenhouse gases like Methane and Carbon dioxide on Zinc oxide and Copper oxide surfaces at room temperature. The simulation based on the Reax-FF inter-atomic potential was used to quantify and illustrate the adsorption process of hydrogen on the chosen adsorbents at different incident energies. Our simulation results have shown that Zinc oxide is a more effective adsorbent for hydrogen than Copper oxide at room temperature. The adsorbent properties and adsorption mechanism remain relatively constant regardless of variations in the incident velocity of the adsorbate. The results of methane adsorption at 300 K indicate that Zinc oxide is a more effective adsorbent than Copper oxide. However, both adsorbents have equal efficiency in adsorbing carbon dioxide at the same temperature. Molecular dynamics simulation at different temperatures ranging from 50 K-450 K reveals that Copper oxide can adsorb methane molecules at low temperatures while Zinc oxide retains its adsorption properties regardless of temperature.

Authors: Chen Jie , Su Yuping , Zhang Yumei , Wu Xiaojun 
Published: July 2023

Abstract
Music emotion classification is becoming an important research direction due to its great significance for the music information retrieval (MIR). For the music emotion classification task, how to fully extract related features from the original music audio is the key to improve classification accuracy. In this paper, we propose a music feature fusion attention (MFFA) model to improve the efficiency of mining music emotional features. The proposed model combines a feature fusion attention (FFA) module and a Bi-directional Gated Recurrent Units (BiGRU) module to extract music emotional features from both spatial and temporal dimensions. Firstly, we use the FFA module as a feature extractor, feeding the log Mel-spectrogram of music audio into it, to obtain more comprehensive and effective feature information through multi-scale feature fusion and multi-layer attention mechanisms. At the same time, global residual connection and local residual connection in the FFA are used to learn features in all aspects. The BiGRU module is then used to further capture the temporal relationships of music sequences, and feature concatenation is used to fuse spatial and temporal features. The experimental results show that the proposed model has 1.2%~7.9% improvement over five other baselines. Also, the ablation experiments demonstrate the effectiveness of the combination of FFA module and BiGRU module of the proposed model.

As a helpful management approach in MPAs, community participation has received substantial attention from researchers worldwide. To identify the research status in the field of community participation in MPAs, 391 papers obtained from the Web of Science were reviewed with bibliometric methods and VOSviewer. The results showed that the number of publications had kept growing from 1994 to 2022. The USA having the most number of publications, followed by Australia. Environmental science was identified as the major thematic area. The studies concentrated on community-based marine resources management, the participation mode of communities and participatory planning and monitoring. Besides, we summarized the experience and lessons of community participation to illustrate the role of community involvement in the construction and management of MPAs. Finally, the outlook for future research was presented based on the analysis above. We recommend promoting cross-disciplinary cooperation and combining quantitative and qualitative methods to support this research. Meanwhile, it was critical to study further the specific path of community participation and fully utilize the local knowledge to supplement scientific data. The current study provided an overview of the characteristics of publications, research trends and primary research methods in the study of community participation in MPAs. The results will help to explore the ways to mitigate conflicts between MPAs and communities. We hope that our study could promote their coordinated and sustainable development and contribute to marine conservation and human well-being.

Authors: Pan Ke-Hao , Chen Ming 
Published: July 2023

Abstract
Objective: To establish the competitive endogenous RNA (ceRNA) regulatory network related to phosphatase and tensin homologue (PTEN) in prostate cancer (PCa), and screen messenger RNA (mRNA), microRNA (miRNA) and long noncoding RNA (lncRNA) related to the prognosis of PCa to provide a theoretical basis for the diagnosis and prognosis of PCa.
Methods: Transcriptome data of 498 prostate cancer samples and 52 normal prostate samples were extracted in Cancer Genome Atlas (TCGA) database and differential expression (DE) lncRNAs, miRNA and mRNA were screened. The CytoHubba plug-in was used to identify the triple regulatory network of hub genes. On this basis, the PTEN-related ceRNA regulatory network was constructed. Kaplan-Meyer method was used to explore the related factors about the prognosis of PRAD patients. The gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) were performed to explore functional annotation and enrichment pathways.
Results: Amount to 1918 DElncRNAs, 68 DEmiRNAs and 2920 DEmRNAs were screened. And 8 lncRNAs, 7 miRNAs and 525 mRNAs were incorporated to build the lncRNA-miRNA-mRNA triple regulatory network by Cytoscape software. The enrichment analysis of GO and KEGG showed that these interaction proteins function mainly enriched in chemotaxis, urogenital system development and cell morphogenesis involved in differentiation. Three lncRNAs (MEG3, AGAP11, and ADAMTS9-AS2), five miRNAs (miR-93-3p, miR-141-3p, miR-222-3p, miR-590-3p and miR-3619-5a) and six mRNAs (NRG1, SHH, TIMP3, CLVS2, NFAT5 and ADAM22) were identified by the Cytoscape plug-in cytoHubba. Kaplan-Meier analysis screened out 2 DEmRNAs(NRG1 and CLVS2), 1 DElncRNAs(MEG3) and 1 DEmiRNA(miR-222-3p), which were associated with the prognosis of PRAD (P<0.05). Finally, we established a PTEN-related MEG3-hsa-miR-222-3p-NRG1/CLVS2 ceRNA network in PRAD. NRG1 and CLVS2 were related with methylation and immune infiltration in PRAD, which were high expressssion in PRAD by Immunohistochemical analysis.
Conclusion: In this study, the key RNAs related to PRAD prognosis are screened out by constructing the PTEN-related ceRNA regulatory network of PRAD, which provides a theoretical basis for the diagnosis and treatment of PRAD.

Published: July 2023

A main goal of current low background physics is the search for rare and novel phenomena beyond the Standard Model of particle physics, e.g. the scattering off of a potential Dark Matter particle inside a CaWO_44 crystal or the neutrinoless double beta decay of Ge nucleus. The success of such searches depends on a reliable background prediction via Monte Carlo simulations. A widely used toolkit to construct these simulations is GEANT4, which offers a wide choice of physics models, so-called physics lists. To facilitate the selection of physics lists for simulations of CaWO_44 and Ge targets, we quantify their impact on the total energy deposition for several test cases.

Abstract
The study estimated the risk due to Cryptosporidium, Giardia, and Ascaris, associated with non-potable water reuse in the city of Jaipur, India. The study first determined the exposure dose of Cryptosporidium, Giardia, and Ascaris based on various wastewater treatment technologies for various scenarios of reuse for six wastewater treatment plants (WWTPs) in the city. The exposure scenarios considered were (1) garden irrigation; (2) working and lounging in the garden; and (3) consumption of crops irrigated with recycled water. The estimated annual risk of infection varied between 8.57 × 10−7 and 1.0 for protozoa and helminths, respectively. The order of treatment processes, in decreasing order of annual risk of infection, was found to be: moving-bed bioreactor (MBBR) technology &gt; activated sludge process (ASP) technology &gt; sequencing batch reactor (SBR) technology. The estimated annual risk was found to be in this order: Ascaris &gt; Giardia &gt; Cryptosporidium. The study also estimated the maximum allowable concentration (Cmax) of pathogen in the effluent for a benchmark value of annual infection of risk equal to 1:10,000, the acceptable level of risk used for drinking water. The estimated Cmax values were found to be 6.54 × 10−5, 1.37 × 10−5, and 2.89 × 10−6 (oo) cysts/mL for Cryptosporidium, Giardia, and Ascaris, respectively.

Published: July 2023

Abstract

The tee structure is an integral part of the water distribution system, and pollutants diffuse in complex ways within the structure. In this paper, the diffusion pattern of contaminants in the tee structure was examined using a combination of numerical simulations and experiments. The coefficient of variation was chosen as an evaluation indicator, and the uniform diffusion length (LU) was defined to quantify the location of uniform diffusion of pollutants in the structure. Several factors were used to investigate pollutant diffusion in the pipe, including pipe diameter, break location, inlet Reynolds number, outlet flow ratio, brine flow rate, and brine density. Results show that the inlet Reynolds number, outlet flow ratio, and pipe diameter all significantly affect pollutant diffusion. The LU increased as the inlet Reynolds number, outlet flow coefficient, and pipe diameter increased. In addition, equations for calculating LU were fitted using dimensional analysis and can be used to predict LU under other conditions as well.

Abstract

Efficient degradation of uranium(VI) (U(VI)) in wastewater is an urgent problem because of the chemical toxicity and radiotoxicity. In this study, the Agx–SnS2 photocatalysts were compounded by a simple hydrothermal method, effectively removing U(VI) under visible light in water. Compared with SnS2, the results indicated that Agx–SnS2 would decrease the crystallinity without destroying the crystal structure. Moreover, it has excellent photocatalytic performance on the degradation rate of U(VI). Ag0.5–SnS2 exhibited a prominent photocatalytic reduction efficiency of UO22+ of about 86.4% under optical light for 75 min. This was attributed to Ag-doped catalysts, which can narrow the band gap and enhance absorption in visible light. Meanwhile, the doping of Ag promoted the separation of photoinduced carriers, so that more photogenerated charges participated in the photocatalytic reaction. The stability and reusability were verified by the cycle test and the potential photocatalytic mechanism was analyzed based on the experiment.

Published: July 2023

Abstract

Microcystis aeruginosa is the dominant species in the blooms of eutrophic lakes such as Taihu Lake in China. Chlorophyll-a is one of the most common indicators to characterize its biomass. The nonlinearity and unsteadiness of the chlorophyll-a sequence decrease the prediction accuracy. In this paper, a secondary decomposition prediction method based on the integration of wavelet decomposition, variational modal decomposition, and gated recurrent unit (WD–VMD–GRU) is proposed. First, the original sequence is decomposed once using wavelet decomposition (WD). Then, the components with higher sample entropy values are decomposed using variational modal decomposition (VMD). Finally, each component is predicted using a gated recurrent unit (GRU), and the final prediction results are obtained by reconstructing each component result. The decomposition effect is ranked as VMD &gt; WD &gt; CEEMDAN &gt; EMD. The WD–VMD–GRU model has a significant advantage compared to the basic model, with an increase of over 6.5% in R2. The secondary decomposition reduces the difficulty of predicting GRU components and has better prediction performance. The RMSE, MAE, and R2 were 1.752, 1.450, 0.969 at 2-day prediction, and 3.169, 2.711, 0.908 at 6-day prediction. Therefore, the WD–VMD–GRU model is superior in accuracy to other methods and can provide a scientific basis for the growth prediction research of M. aeruginosa.

Published: July 2023

O presente artigo propõe uma análise da viabilidade do Espaço Latino-americano e Caribenho de Educação Superior (ENLACES), bem como de seu potencial como agente da regionalidade em face da conjuntura da educação superior na região. Pautou-se na perspectiva do novo regionalismo de Björn Hettne e na abordagem qualitativa, assim como na análise de documentos e na realização de entrevistas semiestruturadas com atores que estão ou estiveram vinculados ao processo de construção do ENLACES; e, para exploração dos dados, foi utilizada a técnica de análise de conteúdo. Constatou-se que, além da complexidade de articular os sistemas de educação superior tão distintos, o próprio ENLACES enfrenta o desafio de conseguir sua consolidação. Diante disso, apesar de haver expectativas quanto à viabilidade desse Espaço, há um grande desafio diante da diversidade acadêmica existente na região. Semelhantemente, seu possível papel como agente no fortalecimento da identidade regional fica comprometido em vista da dificuldade de consolidação.

Published: July 2023

Background:
Subchondral insufficiency fractures (SIF) of the knee joint are prevalent in osteoporosis patients over the age of 55. Early diagnosis of SIF fracture
of the medial femoral condyle is crucial for delaying disease progression, early therapy, and potential disease reversal. Magnetic resonance
imaging (MRI) is useful in detecting SIF, which is often undetectable on initial radiographs.

:
This study aimed at developing a grading system for subchondral insufficiency fractures (SIF) based on MRI to predict outcomes and evaluate risk
factors.

Methods:
In this study, MRI was used to examine SIF risk variables in the medial condyle of the femur to help clinicians diagnose, treat, and delay the condition. A total of 386 patients with SIF from 2019 to 2021 were retrospectively analyzed and divided into 106 patients in the disease group and 280 patients in the control group according to whether they had SIF. The lesion site, meniscus, ligament, and other parameters were evaluated and compared. At the same time, a grading system was introduced to stratify and statistically analyze the size of the lesion area, the degree of bone marrow edema (BME), meniscus tears, and other parameters in the patients.

Results:
Most SIF were low-grade (LG) fractures, and the predictors of LG and high-grade (HG) fractures included heel tear (P =0.031), degree of medial malleolus degeneration (P < 0.001), advanced age (P < 0.001), and lesion size (P < 0.001). The prognostic factors that showed significant differences between the two groups included age (P =0.027), gender (P =0.005), side (P =0.005), medial tibial plateau injury (P < 0.0001), femoral medullary bone marrow edema (P < 0.0001), medial tibial plateau bone marrow edema (P < 0.0001), meniscus body partial injury (P =0.016), heel tear (P =0.001), anterior cruciate ligament injury (P =0.002), and medial collateral ligament injury (P < 0.0001).

Conclusion:
This current study proposed an MRI-based grading system for inferior condylar fractures of the femur, in which HG inferior condylar fractures are associated with severe medial malleolus degeneration, advanced age, lesion size (correlation), and meniscus heel tears.
