Rhizosphere microorganisms are considered an extension of plants, representing critical actors involved in the promotion of plant nutrient intake from the surrounding environment. Consequently, a great focus is being made on soil microorganisms since they are considered a promising source for crop resilience improvements under a global climate change scenario. To explore bacterial and fungal communities from arid soils in vineyards and their surroundings from two regions with very different climate and tillage histories, an amplicon sequencing analysis was performed. Specifically, Santa Rosa (SR) is in a region commonly known as the first zone, characterised by low altitude (607 m.a.s.l., Winkler V), while Gualtallary (G) is in the Uco Valley Zone, a region with high altitude (1245 m.a.s.l., Winkler III); both in the productive wine region of Mendoza. SR is characterised by its long cultivation history, while G is a recently cultivated region. Topsoil samples were collected and used for bacterial and fungal community profile characterisation. Ascomycota was the predominant phylum (38–97 %) in mycobiome composition, whereas Proteobacteria was the most abundant bacterial phylum (26–34 %) in both regions. Moreover, the main factor explaining microbiome differences between regions was the carbon-to-nitrogen ratio. Anaerolineae and Gammaproteobacteria were a distinctive bacterial class in SR-cultivated soils. Azospirillales were highly abundant in SR uncultivated soils, while Rhizobiales were differentially abundant in G uncultivated soils. Regarding functional analysis, soils from SR showed a higher denitrification activity of nitrifiers as well as glucose-related metabolism, while in G soils, bacterial photosynthesis activities were a differential trait. In addition, Actinobacteria abundance was lower in SR-cultivated soils, indicating a higher susceptibility of this phylum to grapevine crop practices. These results allow the development of hypothetical models of the local microbial resources and their contribution to grapevine nutrition, which is highly important to elaborate recommendations for grapevine management to preserve soil health in vine areas of Mendoza.

Hospital licensing is processed through the OSS-RBA system, in the OSS-RBA system private hospitals are included in KBLI 86103 where single purpose provisions apply. The application of single purpose to KBLI 86103 means that foundation legal entities as owners of private hospitals cannot have other business activities or can only have a single business activity. The problem raised in this study is how is the application of KBLI 86103 Single Purpose in the OSS-RBA system for hospital licensing with foundation legal entities (a study at the Yogyakarta PDHI Islamic Hospital)? The research method used is a normative juridical method with a statutory approach. The results of this study conclude that the application of single purpose provisions to KBLI 86103 in the OSS-RBA system is contrary to the provisions of the applicable laws and regulations.

Authors: Ulya Inayatul , Nurhadi Agus
Published: February 2023

Sufistic education and the rise of the tarekat community in Muslim middle class groups is a phenomenon that shows the rise of religion in the public sphere. The religious expression displayed by the Muslim middle class is a form of religious accommodation to current life which turns out to be able to work harmoniously. Even religion can be a solution to life on the problems experienced by modern society. This article explains that the sufistic education that was followed by the Muslim middle class became a medium to construct their religiousity. They make the tarekat an identity that distinguishes them from other Muslim communities. Sufistic education that is followed by Muslim middle class can be seen in two dimensions, First, the individual dimension that emphasizes the efforts of Muslim middle class to carry out  the practice of the tarekat in order to build piety, improve themselves, build better character, uphold the values moral and religious values in daily life. Second, the social dimension is about the needs of the Muslim middle class to join in the tarekat community in order to build a collective identity that functions strategically in a better social life

Then the data is analysed by means of data reduction, data presentation and drawing conclusions and verification. The results of this study indicate that love education contains five principles that must be realized by all educators, the fifth is that education is gradual and continuous; students' abilities are different; moral and then intellectual education; Mental and intellectual education must involve the community and students must always ask for God's grace. Meanwhile, in the pedagogical approach, the service-learning strategy is used to instill love and affection in education.
Multiple Representation Ability of High School Students in Physics: A Study of Modern Response Theory
Authors: AM Muh. Asriadi , Istiyono Edi
Published: February 2023

Physics education emphasizes students' ability to represent a problem and then choose alternative solutions from various perspectives. However, teachers still very rarely use this ability as the focus of assessment. The purpose of this study is to describe the results of an assessment of the ability to represent multiple physics in each of its components. This is survey research that takes a quantitative approach. This study's sample included 287 high school students from Yogyakartam using cluster sampling. The instrument used is a physics multiple representation ability test that has been tested for validity, reliability, and item quality using IRT 1 PL analysis. According to the measurement results, physics high school students' dual representation ability in all aspects, namely mathematical representation, graphic representation, image representation, and verbal representation, is in the low category. However, according to the four existing components, the mathematical component is the highest and the verbal component is the lowest. So this finding can be a reference for teachers in improving the quality of physics teaching.

Authors: Vologina E.G. , Sturm M. , Vorob’eva S.S.
Published: February 2023

—The paper provides the results of experiments with sediment traps in the deep-water part of the South Basin of Lake Baikal (depth of 1366 m), installed from March 2015 to March 2016 in order to study recent sedimentation within the lake. We present new data on total fluxes of particulate matter and fluxes of biogenic components (SiO2biog, Сorg, and Ntot) at different depths of the water column both for the whole year and for individual periods of the year. Diatom analyses were carried out for all obtained samples. The total flux of sedimentary material averaged 94.9 g/m2/y; the average fluxes of SiO2biog, Сorg, and Ntot were 23.9, 11.6, and 0.94 g/m2/y, respectively. The molar C/N ratio varies from 11 to 21 and indicates a predominance of allochthonous material in almost all samples. Maximum fluxes of sedimentary matter were recorded from 20 June to 20 July 2015. This period corresponds to the bloom of diatoms of the species Synedra acus. This species amounts to >94% of the total diatom content in all samples taken during this year. The recent predominance of Synedra acus in the water column, as well as in the surface bottom sediments of South Baikal, is probably due to the climate warming.
Boosting Reaction Rate of Acids for Better Acid Fracturing Stimulation of Dolomite-Rich Formations
Authors: Sayed Mohammed A. , Cairns Amy J. , Chang Fakuen F.
Published: February 2023

Carbonate reservoirs can be stimulated by injecting acids to boost the rate of hydrocarbon production from low-permeability zones via the creation of conductive pathways. The reaction rate between the acidizing fluid and rock matrix is a key parameter in determining the success of stimulation treatments. Dolomite-rich formations are known to exhibit slower reaction kinetics as compared to calcite. As a result, some acid fracturing treatments fall short of creating an extended fracture or the desirable etching pattern on the fracture faces, thus limiting hydrocarbon flow. Accordingly, the development of an acid package to boost the dolomite dissolution rate will be advantageous to the efficiency of the stimulation treatment in dolomite-rich reservoirs.

Accelerating the reaction rate of dolomite with strong mineral acid (i.e., hydrochloric acid, HCl) can be achieved through an additive-driven chemical approach based on the addition of judiciously selected sulfonate-based surfactants. To pinpoint the optimal surfactant(s) type and concentration, static dissolution testing was performed under ambient conditions using outcrop dolomite core samples (Silurian and Guelph). Each core sample was reacted with 28 wt% HCl in the presence and absence of sulfonate-based surfactant additives for a predetermined time. Selected surfactants are used in comprehensive reaction kinetics studies at reservoir conditions using a rotating disk apparatus (RDA).

Based on the results of the ambient screening tests, three formulations were found to accelerate the reaction rate by up to 30% as compared to using 28 wt% HCl without the additive(s). The kinetics data collected at a pressure of 3,000 psi and temperatures of 175 up to 300°F showed that the reaction rate of Guelph dolomite can be accelerated by as much as 17–55% with one of the formulations. Coreflood experiments showed an increase in the acid PV to breakthrough (PVBT) when the surfactant package was added to the acid formulation pointing to a rise in the reaction rate of dolomite and the developed acid formulations. The acid formulations showed an improvement in the dolomite and acid reaction rate, which creates the opportunity to apply these formulations in the field to improve the outcome of acid fracturing treatments in dolomite-rich reservoirs.
Adherence enhancing interventions for pharmacological and oxygen therapy in patients with COPD: protocol for a systematic review and component network meta-analyses
Authors: Ammous Omar , Andreas Stefan , Friede Tim , Kampo Regina , Schwarz Sarah , Wollsching-Strobel Maximilian , Salem Susanna , Windisch Wolfram , Mathes Tim
Published: February 2023

Background: Chronic Obstructive Pulmonary Disease (COPD) is characterised by hyperinflation and expiratory airflow limitation due to long-term exposure to irritants. The variety and complexity of COPD treatment and the possible added comorbidities may make the patients find it difficult to cope with the required medications. That’s why supporting patients' adherence is critical because not taking medications correctly increases the risk of complications and creates an additional financial burden. A range of interventions aiming to improve patient adherence were used, and most of them are complex since they involve a mix of elements. Furthermore, despite the variety of available tools, assessing adherence is challenging because clinicians usually don’t get a concrete judgement if their patients followed their treatment plan reliably.
Methods: We aim to evaluate the effectiveness of adherence-enhancing interventions for COPD patients, explore which intervention (component) works for which patients and check the factors influencing the implementation and participant responses. We will include all studies investigating the effect of adherence-enhancing intervention on patients with COPD. We plan to perform two patient interviews (one before and one after the systematic review) and follow a sequential approach to integrating qualitative and quantitative information. The first interview aims to understand patients’ needs and prioritise the selection of the outcomes. The second interview will be conducted after the evidence synthesis to present the results to patients. Two reviewers with complementary expertise will perform the screening, data extraction and risk of bias assessment. We will perform two meta-analyses: the first will be pair-wise random-effects meta-analyses to combine homogeneous studies. Secondly, we will perform random-effects component network meta-analyses to identify the most effective components and combinations of components. To determine the degree of complexity, we will use the iCAT_SR checklist, and then, following a logical model, we will group the interventions according to prespecified criteria.
Discussion: This systematic review aims to point out the most effective and implementable adherence-enhancing interventions by using methods for synthesising evidence on complex interventions and involving COPD patients all along with the review process.

Published: February 2023

Purpose: This study aimed to evaluate the comparison of the diagnostic performance of 18F-FDG PET/CT and 18F-NaF PET/CT in breast cancer patients with bone metastases.
Materials and Methods: The databases PubMed and Embase were used to search the English literature on the diagnostic performance of 18F-FDG PET/CT and 18F-NaF PET/CT for breast cancer bone metastases. Two authors independently extracted data. Studies were selected for analysis if the data presented in the study reports could be used to construct a 2×2 contingency table. The methodology quality of the enrolled studies was assessed by QUADAS-2, and forest plots were generated based on the sensitivity and specificity of 18F-FDG PET/CT versus 18F-NaF PET/CT in the diagnosis of breast cancer bone metastases. Stata Software Version 14.0 (Stata Corporation, College Station, TX, USA) was used for statistical processing.
Results: A total of 14 articles were identified, eight of which were about the analysis of 18F-FDG PET/CT in the diagnosis of breast cancer bone metastases, five of which were about 18F-NaF PET/CT, and one article was an analysis of the diagnostic performance of both them. The studies of 18F-FDG PET/CT and 18F-NaF PET/CT included 530 and 389 patients, respectively. The pooled sensitivities were 0.88 (95% CI: 0.80-0.99) for 18F-FDG PET/CT and 0.98 (95% CI: 0.92-1.00) for 18F-NaF PET/CT, respectively, and the pooled specificities were 0.99 (95% CI: 0.98-1.00) and 0.91 (95% CI: 0.76-0.97), respectively. The area under the SROC curve of both 18F-FDG PET/CT and 18F-NaF PET/CT were 0.99 (95%CI: 0.98-1.00),, of which 18F-FDG PET/CT 1038 lesions were included and a sensitivity of 0.84 (95% CI: 0.67-1.00) and specificity of 1.00 (95% CI: 0.98-1.00) were reported for lesion-based 18F-FDG PET/CT for BM. Compared with 18F-FDG PET/CT, 18F-NaF PET/CT showed higher sensitivity (98% vs 88%, p= 0.09), but lower specificity (91% vs 99%, p=0.13), both of which were not statistically significant.
Conclusions: The results showed that 18F-NaF PET/CT and 18F-FDG PET/CT are accurate methods for detecting bone metastases in breast cancer patients. The diagnostic accuracy of both is the same.

Published: February 2023

Note: Please see pdf for full abstract with equations.
This study investigated the in-situ chemical oxidation of the pharmaceutical compound carbamazepine (CBZ) using the combination of hydrodynamic cavitation (HC) and persulfate anion (S2O82-) and simultaneous activation of S2O82- anion by HC, UV–C irradiation and ZnO/ZnFe2O4 particles. Results show that the HC-based UV/persulfate / ZnO/ZnFe2O4 process effectively achieved 98.13 ± 1.03 % CBZ degradation. In binary oxidation system, viz. HC+UV, HC+S2O82-, HC+ZnO/ZnFe2O4, and UV+ZnO/ZnFe2O4, significantly higher 65.73% degradation was obtained using HC+S2O82- system. CBZ degradation profiles were analyzed using a mathematical kinetic model based on the reaction network. Experimental and simulated degradation profiles were matched with the initial [Fe2+]/[H2O2] ratio as a manipulation parameter. The closest match between experimental and simulated CBZ degradation profiles was obtained for the initial [Fe2+]/[H2O2] ratio = 10, which indicated enhanced leaching from the surface of ZnO/ZnFe2O4 particles. The results demonstrated that HC based persulfate oxidation system might prevent emergent pollutants like carbamazepine from polluting water.

We examine the information sharing behavior of stakeholders in the sustainable supply chain of water transfer projects in the context of "Migrating to Cloud, Using Digital Tools and Enabling Intelligence". We explored the evolution of the information sharing behavior of supply chain stakeholders using the China South-North Water Transfer Project as an example, and conducted simulations using MATLAB software to verify the optimal path of the supply chain. The results show that the information sharing behavior of stakeholders in the sustainable supply chain of water transfer projects is influenced by the water consumption of each municipality, the payment strategy of the South-North Water Transfer Project Fund and the cost of updating big data technology. Whether to obtain downstream demand information from the cloud. The upstream and downstream water supply companies should integrate the use of big data and real-time cloud-based intelligent services to make themselves and their partners more profitable in both directions, and to promote the overall coordinated development of a sustainable supply chain for water transfer projects.
Unraveling mucolipidosis type III gamma through whole genome sequencing in late-onset retinitis pigmentosa: a case report
Authors: De Geer Karl , Mascianica Katarzyna , Naess Karin , Sardh Eliane , Lindstrand Anna , Björck Erik
Published: February 2023

Background: We describe the case of a 47-year-old man referred to a retinal clinic and diagnosed with late-onset retinitis pigmentosa. Surprisingly, genetic testing revealed compound heterozygous pathogenic variants in GNPTG, leading to the diagnosis of the autosomal recessive lysosomal storage disorder mucolipidosis type III gamma. Mucolipidosis type III gamma is typically diagnosed during childhood due to symptoms relating to skeletal dysplasia. Retinal dystrophy is not a common phenotypic feature.
Case presentation: Ophthalmologic examination was consistent with a mild form of retinitis pigmentosa and included fundus photography, measurement of best-corrected visual acuity, optical coherence tomography, electroretinogram and visual field testing. Extraocular findings included joint restriction and pains from an early age leading to bilateral hip replacement by age 30, aortic insufficiency, and hypertension. Genetic analysis was performed by whole genome sequencing filtered for a gene panel of 325 genes associated with retinal disease. Two compound heterozygous pathogenic variants were identified in GNPTG, c.347_349del and c.607dup. The diagnosis of mucolipidosis type III gamma was confirmed biochemically by measurement of increased activities of specific lysosomal enzymes in plasma.
Conclusion: To our knowledge this is the first description of retinitis pigmentosa caused by compound heterozygous variants in GNPTG, providing further indications that late-onset retinal dystrophy is part of the phenotypic spectrum of mucolipidosis type III gamma.

Authors: Deng Ruyue , Yan Shiyuan , Zhang Lin , Hou Yanjie , Wang Hao , Zhang Wenjing , Yao Jun
Published: February 2023

Background
Intergenerational relationships profoundly affect older parents’ mental health. However, few studies have shed light on its mechanisms in familistic cultures and migration contexts. The current study aimed to investigate the associations of intergenerational emotional cohesion (IEC) and depression among the Chinese older immigrants, and the mediating roles of loneliness and perceived stress.
Methods
Obtained from a cross-sectional survey conducted in Nanjing, China, the research data involved 654 older immigrants. Variables were measured using the intergenerational solidarity inventory, 3-item R-UCLA Loneliness Scale, Perceived Stress Scale, and 9-item Patient Health Questionnaire (PHQ-9).
Results
There is a negative correlation exists between IEC and depression. Through IEC, three significant mediation pathways were identified that directly affect depression: (1) loneliness (β=-0.063; Ratio = 18.21%), (2) perceived stress (β=-0.085; Ratio = 24.57%), and (3) loneliness and perceived stress (β=-0.033; Ratio = 9.53%).
Discussion
This study advances our understanding of the mechanism through which IEC influences depression in Chinese older immigrants. A strong IEC can reduce depressive symptoms by relieving loneliness and perceived stress.

A novel analysis of Hopf bifurcation for a fractional-order neural network involving mixed delays
Authors: Zhang Yanxia , Li Long
Published: February 2023

This paper provides an extensive binary fractional-order neural network system with mixed delays consisting of two discrete delays and two distributed delays and emphasizes its bifurcating methods and theories. First, the original system is transformed into a five-neuron fractional-order neural network with four delays by introducing three virtual neurons. And then we select different delays as parameters inducing bifurcation to determine the ranges of guaranteeing the steady state response of the system. Some sufficient conditions for the occurrence of Hopf bifurcation are established. In the end, the correctness of the obtained conclusions is verified with the support of numerical simulations. It is found that both discrete and distributed delays play a key role in the Hopf bifurcation of fractional-order neural networks, especially the mean delay in distributed term has a great impact on the critical values controlling bifurcation.
How to compute suitable vicinity parameter and sampling time of recurrence analysis
Authors: Prado Thiago Lima , Machado Vandertone Santos , Corso Gilberto , Lima Gustavo Zampier dos Santos , Lopes Sergio Roberto
Published: February 2023

We show how the maximum of recurrence-mi\-cro\-states entropy configures a new way to properly compute appropriate recurrence vicinity parameter and time sampling to perform recurrence analysis of continuous data. For experimental data, we show the same procedure may be used to find the optimum sampling or to perform down-sampling of the data, preserving recurrence meaning and adjusting the ideal sampling. The new method retrieves results obtained using traditional methods with the advantage of being independent of any free parameter, since all parameter dependencies are automatically set. Our results are also less sensitive to noise when experimental data is used. Due to the automatized way to capture suitable recurrence parameters, the method is adequate for using in autonomous numerical algorithms, allowing the recovery of relevant recurrence information embedded in time series (including over-sampled data), rationalizing the process of data acquisition and allowing only relevant data to be collected.

Published: February 2023

Building code violations have negatively affected Tehran's spatial development significantly over the last three decades. This study was carried out to answer the question of what the status and factors of building violations and spatial changes were in Tehran's districts in the first decade 1990s and 2000s, when rapid urban development was at its peak. This study's statistical population included all buildings in the twenty-two districts of Tehran. In addition, the data and information for this study were gathered through library and documentary research. Furthermore, descriptive statistical methods were used to explain and interpret the data, and Geographic Information Systems (GIS) were used to represent the results. According to the findings, financial incentives were the most important motivators for committing these violations. One of the most important spatial developments in the Tehran metropolis during this time is the conflict between the Master Plan for the city and population growth, per-capita residential, commercial, and military land use. As a result, areas 1 to 7 and residential structures accounted for 56% of Tehran's total area of residential buildings and 41.8% of the city's population in 2001, respectively, a rise of 2.9% and 34.8%. Additionally, other public institutions increased the area of residential buildings and the population of this area by 46.5% and 42.5% during this time period, respectively, by violating building codes, particularly in area 4 of the city.

Authors: Lan Xiaoyi , Hua Chen
Published: February 2023

In response to the policy development, the manufacturing industry is undergoing intelligent technology transformation. Online orders are characterized by multiple varieties and small batches. Therefore, in order to meet the personalized needs of more customers, it is necessary to transform the traditional production mode into the intelligent factory mode. Intelligent factories can realize green and sustainable development. Using intelligent robot technology to complete programming to design and process is an important research direction in related fields. In this context, this study strives to design a unitary production scheduling algorithm, which is implemented based on artificial intelligence technology. After testing, this algorithm has the best performance, the shortest running time, relatively low power consumption and short product processing cycle. The system design framework includes three parts: the communication design between physical control equipment and PC, the interactive control software design of PC, and the virtual controlled object model design. From the research results, it can be concluded that the realization of production scheduling algorithm design for intelligent manufacturing cells can help enterprises to make rational allocation of order size and resources, so as to improve production efficiency while taking into account the low-carbon production concept widely promoted by the international community. In this paper, a kind of effective production scheduling algorithm is studied by introducing AI technology into the field of intelligent manufacturing cell.

Published: February 2023

Amaranths are dicotyledonous plants with high yield potential, a high mineral uptake rate, short days, and high adaptability. It has been extensively investigated as a model C4 plant. The objectives of the current study were to estimate genetic diversity, heritability, and genetic advance for yield and yield-contributing traits of amaranth genotypes based on agro-morphological traits. The study was done on one hundred twenty amaranth genotypes planted over two growing seasons using an alpha lattice design with two replications. The analysis of variance showed the presence of significant variation (P ≤ 0.001) between genotypes, years, and their interactions for most of the studied traits. Among the genotypes, based on their performance, promising genotypes KAZ-059, 225713, KAZ-058 and KEN-019, 242530, and 212890 exhibited higher leaf area, branch number, and plant height at maturity, and plant height at flowering. Selection based on these traits could be effective for amaranth leaf yield improvement. On the other hand, KEN-016, KEN-020, KAZ-060, KEN-010, KEN-018, and 22571 produced high grain yield along with better leaf area, axillary inflorescence length, terminal inflorescence lateral length, terminal inflorescence stalk length, grain sink filling rate, and thousand seed weight, indicating phenotypic-based selection on these traits might be reliable for grain yield improvement in amaranth genotypes. These genotypes were chosen as a result due to their high yield potential and good yield-related traits. Future selection efforts for amaranth should therefore continue to evaluate the genotypes under various environmental conditions. These genotypes were selected as a result because they had a high potential for yield and desirable traits that might boost yield.

Published: February 2023

The global high prevalence of COVID-19 is a major challenge for health professionals and patients. SARS-CoV-2 virus mutate predominantly in the spike proteins, whilst the other key viral components remain stable. Previous studies have shown that the human oral cavity can potentially act as reservoir of the SARS-CoV-2 virus. COVID-19 can cause severe oral mucosa lesions and is likely to be connected with poor periodontal conditions. However, the consequence of SARS-CoV-2 viral infection on human oral health has not been systematically examined. In this research, we aimed to study the pathogenicity of SARS-CoV-2 viral components on human periodontal tissues and cells. We found that by exposing to SARS-CoV-2, especially to the viral envelope and membrane proteins, the human periodontal fibroblasts could develop fibrotic pathogenic phenotypes, including hyperproliferation that was concomitant induced together with increased apoptosis and senescence. The fibrotic degeneration was mediated by a down-regulation of mitochondrial β-oxidation in the fibroblasts. Fatty acid β-oxidation inhibitor, etomoxir treatment could mirror the same pathological consequence on the cells, similar to SARS-CoV-2 infection. Our results therefore provide novel mechanistic insights into how SARS-CoV-2 infection can affect human periodontal health at the cell and molecular level with potential new therapeutic targets for COVID-19 induced fibrosis.

Published: February 2023

Background Uterine arteriovenous malformation(AVM) refers to the abnormal direct traffic between uterine arteries and veins, which can be characterized by the imaging examination, showing increased uterine vascularity and arteriovenous shunting. However, similar imaging manifestations can also be seen in a variety of conditions including retained production of conception, gestational trophoblastic disease, placental polyp, and vascular neoplasm.
Case presentation Here we present a case of a 42-year-old woman who was suspected of suffering uterine AVM indicated by Doppler sonography and magnetic resonance imaging but was finally diagnosed with a persistent ectopic pregnancy by pathology after laparoscopy. She recovered well after surgery.
Conclusion Uterine AVM is a rare and serious condition. In general, it presents special radiological manifestations. However, when complicated with other diseases it can also be distorting. Standardized diagnosis and management are important.

Based on the research and investigation of the psycho-educational development and assessment of college students, this paper designs an interactive system for automatic evaluation of the psychoeducation of college students, which is based on the KNN data classification model and the current technical and environmental conditions. Based on the data and personal information of a college student's psychological census, screen the students' psychological evaluation data, analyzes the key information of the data, obtains the association rules of each factor, analyzes the experimental results. Aiming at the problem that KNN algorithm has low classification accuracy on unbalanced data, we proposes a weighted KNN hybrid algorithm. The harmonic weighted KNN classifier is added to the SVM-KNN classifier for fitting, and the SVM-KNN hybrid algorithm is jointly established. Combined with the principle of SVM-KNN hybrid data classifier, the improved algorithm is applied to a wider range of data value areas, and the appropriate algorithm is selected for data classification and prediction by judging the threshold size. For the data classification calculation method, the Euclidean distance calculation method is generally used to calculate the point-to-point distance in the plane coordinate system, as for hyper plane high-dimensional data, the improved algorithm uses a more suitable kernel function calculation method. According to the designed experimental step program, a series of basic performance such as the calculation rate of the algorithm and the system are tested, and the results show that it can be satisfied, which proves that the interactive automatic evaluation system of College Students' psychological education designed in this paper can effectively understand the psychological status of college students at this stage, find the students who need to focus on psychological counseling, and carry out psychological health education, so as to provide reference for the actual college students' psychological health education.

Background: Previous studies have shown that blockade of programmed cell death-1 (PD-1) or programmed cell death- Ligand-1 (PD-L1) may improve anti-HBV responses in vitro and woodchuck models. However, clinical data was limited on the role of PD-1 inhibitors in patients with chronic HBV infection. We aimed to observe the changes ofserum HBsAgand HBV-DNA levels in cancer patients under PD-1 inhibitor-based therapies and identify the risk factors associated with HBsAg fluctuations and HBV reactivation (HBVr).Methods: A retrospective study including HBsAg-positive cancer patients who received PD-1 inhibitors between July 2019 and December 2022 was undertaken. Serum HBsAg and HBV-DNA level changes, the incidence of HBsAg loss, HBVr and immune-related adverse events (irAEs) were investigated. Univariable and multivariable analysis were performed to identify the risk factors for significant HBsAg fluctuations and HBVr.Results: 121 patients were eligible to the study. With concurrent use of antiviral agents, patients with baseline HBsAg within [50 to 500) IU/ml mostly had HBsAg decrease, viral replication was inhibited effectively. HBsAg loss, HBVr and irAEs were developed in 6 patients (4.96%), 6 patients (4.96%) and 14 patients (11.57%), respectively. Multivariable analysis showed baseline HBsAg <100 IU/ml (P=0.01) was the only significant risk factor for HBsAg decrease, irAEs occurrence was the only significant risk factor for HBVr (P=0.03), while no factors were identified for HBsAg increase.Conclusions: PD-1 inhibitor combined with NAs may exert therapeutic potential for chronic HBV infection in cancer patients, attention also should be payed to its safety.

We infer the temporal changes in the pressure sources that induced crustal deformation during the 2018 Shinmoe-dake eruption using strain and tilt observations and discern that the deep magmatic activity associated with the early stage of this eruption began approximately 19 hours earlier than the previously defined onset of magmatic activity. Distinct tilt changes were observed from around 09:00 on 6 March to 12:00 on 8 March 2018 (JST), coincident with observed lava outflow into the crater and lava dome formation. Existing studies have attributed this tilt change to the onset of the deflation of a spherical pressure source located at ~ 7 km bsl (below sea level) to the northwest of Shinmoe-dake. Here we examine strain and tilt data that were acquired in the Kirishima volcanic group, and we find that the distinct changes in the measured strain at Isa-Yoshimatsu Observatory began at around 14:00 on 5 March. This change can be explained by the deflation of a spherical pressure source, thereby suggesting that the onset of magma ascent was earlier than previously thought. The time variation in the spherical pressure source is estimated using the time-dependent inversion of the Ensemble Kalman Filter; the deflation source ascended from ~ 11 to 7 km bsl during Phase 1 (14:00 on 5 March to 06:00 on 6 March) and descended from 7 to 8 km bsl during Phase 2 (06:00 on 6 March to 12:00 on 8 March). Interferometric synthetic aperture radar analysis suggests that a dike intrusion had occurred just below Shinmoe-dake crater until 5 March, and this inflatable crustal deformation is attributed to the emplacement of residual volcanic fluids from the 2011 eruption. It is also known that the surface eruptive activity increased during Phase 1, including an increase in ash venting from the night of 5 March. These strain and tilt observations therefore suggest that magma ascended from ~ 11 km bsl to the magma reservoir at 7 km bsl during Phase 1, followed by a deflation of the magma reservoir during Phase 2 due to the large magma supply to the surface.

Published: February 2023

It is vital to develop a quick and reliable approach for nitrobenzene in gas phase detection. In this work, the quartz crystal microbalance (QCM) platform was used to take advantage of the porphyrin-based metal-organic frameworks (MOFs) of PCN-224 as a novel sensing material for the sensitive and selective detection of nitrobenzene vapor. Besides, a quick response time of only 16 s was achieved. Meanwhile, the frequency shift in gas sensor could be proportionally quenched in correlation with the concentration of nitrobenzene vapor. Additionally, this PCN-224-based sensor demonstrated great stability to nitrobenzene vapor. This foreshadowed the huge potential of nitrobenzene detection in gas phase for practical applications in public security.
