Prediction of post-operative clinical parameters in posterior scoliosis surgery through an adaptive neuro-fuzzy interface system
Authors: ABEDI Rasoul 
Published: April 2023

Abstract
Background and Objective: Postoperative clinical indices should be estimated accurately in scoliosis correction surgeries, which have been analyzed in various studies such as experimental (in vitro or in vivo) trials through different modeling methods (finite element or multibody analysis). These costly and time-consuming methods can only be conducted on a large number of scoliotic patients. An adaptive neuro-fuzzy interface system (ANFIS) is used in this study to estimate the postoperative cobb and thoracic kyphosis angles in adolescent idiopathic scoliosis patients undergoing posterior scoliosis correction surgeries.
Methods: Four groups of 55 patients with distinct preoperative clinical indices (thoracic cobb and pelvic incidence) were considered the ANFIS inputs, whereas postoperative thoracic cobb and kyphosis angles were used as the outputs. For robustness evaluation, the predicted values of postoperative angles were compared with measurements by calculating the root mean square errors and clinical correction deviation indices (the relative deviation of postoperative predicted angles from the real angles).
Results: The least root mean square errors (3.0º and 6.3° for the main thoracic cobb and thoracic kyphosis estimations, respectively) were recorded in the group with the main thoracic cobb, pelvic incidence, thoracic kyphosis, and T1 spinopelvic inclination used as inputs. The clinical correction deviation indices were calculated 0.0086 and 0.0641 for cobb angles in two cases and 0.0534 and 0.2879 for thoracic kyphosis in two other cases.
Conclusion: Greater differences between preoperative and postoperative cobb angles compared with those of thoracic kyphosis decreased the root-mean-square errors and clinical deviation indices but improved accuracy.

Published: April 2023

Abstract
Seasonal cycle of radio refractivity aloft the tropical region have been studied in relation to the migration of the Intertropical Convergence Zone (ITCZ). Radio refractivity values were calculated from meteorological parameters obtained from the archive of the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-Interim). ITCZ position is obtained using maritime and continental winds. Refractivity conditions of anomalous radio propagation were evaluated from refractivity using ITU-recommendation. Multilinear empirical model was developed from ITCZ position determinant factors and refractivity values. The performance of the model was evaluated against ITU-R values using standard metrics. The result showed that the values of refractivity gradient and the position of the ITCZ vary seasonally across Nigeria. ITCZ reached its maximum position northward in August with highest value of refractivity gradient ranges between − 100 N-units/km and − 50 N-units/km across the regions. with the movement of ITCZ across Nigeria. High values of refractivity gradient ranges between Southward position of ITCZ correlate with minimum position of refractivity gradient, which typified ducting. Ducting occurrence prevailed around the ITCZ position.

Abstract
The kinetics of the oxidation reaction of hydroxyzine hydrochloride with potassium hydrogen peroxomonosulfate was studied depending on the pH of the medium. It was established for the first time that the kinetics of the reaction of N-oxidation of hydroxyzine obeyed the general laws of the mechanism of specific acid-base catalysis, proceeded quantitatively and stoichiometrically according to the mechanism of nucleophilic substitution of the β-oxygen atom of the peroxyacid group of peroxomonosulfate ions. It was shown that quantitative oxidation was achieved in 1–1.5 minutes at pH 8.0–8.5. The only reaction product was hydroxyzine N-oxide. A scheme of the oxidation process was proposed. Techniques were developed and the possibility of quantitative determination of hydroxyzine hydrochloride in the substance and tablets of 25 mg by iodometry using Oxone as an analytical reagent was shown. A known excess of reagent was added, and after a predetermined time, the residual reagent was determined iodometrically. RSD ≤ 1.52%. (x̅ - µ)· 100 / µ < RSD. The procedures had several advantages such as speed, simplicity, accuracy, selectivity, and cost-effectiveness, and therefore could be easily adapted by quality control laboratories for routine analysis.

Published: April 2023

Abstract
To prevent corrosion damage in aggressive environments such as seawater, metallic surfaces are usually coated with corrosion inhibitors typically made of organic molecules. Unfortunately, these inhibitors generally exhibit environmental toxicity, affecting living organisms and leaving harmful chemicals in natural habitats. Thus, there is a strong need to develop greener corrosion inhibitors that are chemically and mechanically robust but do not leach toxic chemicals. Here, we show that the recombinant protein rMrCP20 from the adhesive cement protein of the barnacle Megabalanus rosa efficiently protects AH36 steel against corrosion under high salt conditions mimicking the marine environment. We reveal that these anti-corrosion properties are linked to the protein’s biophysical properties, namely its strong adsorption to surfaces combined with its interaction with free Fe ions released by steel substrates, which form a stable layer that increases the coating’s impedance and delays corrosion. Our findings highlight the synergistic action of rMrCP20 in preventing corrosion and provide molecular-level guidelines to develop alternative green corrosion inhibitor additives.

Published: April 2023

Abstract
This work aims to analyze the performance of the transmission of wireless compressed-image over Discrete Sine Transform (DST)-Based OFDMA (DST-OFDMA) systems. When multimedia data, such as images, is sent over OFDMA it consumes a huge bandwidth during the transmission. Therefore, it is suitable to compress the transmitted images to reduce the required bandwidth. Research on image compression over wireless communication systems is necessitated by the need to improve the bandwidth utilization and energy efficiency of the systems. This work evaluates the performance of wireless compressed-image transmission over DST-OFDMA systems and considers different modulation schemes including 16QAM and QPSK, as well as different subcarriers mapping schemes (localized and interleaved) over vehicular A, SUI3 and uniform channels. The minimum Signal-to-Noise Ratio (SNR) required to recover the compressed image that was transmitted is computed. Nine standard compression techniques are used for analyzing the performance. Generally, the obtained results shown that the performance of DST-OFDMA is better than DFT-OFDMA especially when QPSK modulation is used over SUI3 channel model. Simulation results also demonstrate that the smallest value of SNR required to recover a compressed transmitted image obtained by the interleaved DST-OFDMA (DST-IOFDMA) system using the SPIHT_3D compression method and QPSK modulation over the SUI3 channel model is approximately 18 dB.

Published: April 2023

Abstract
Introduction
Perinatal anoxia remains an important public health problem as it can lead to hypoxic-ischaemic encephalopathy (HIE) and cause significant neonatal mortality and morbidity. The mechanisms of the fetal brain’s response to hypoxia are still unclear and current methods of in utero HIE prediction are not reliable. In this study, we directly analysed the brain response to hypoxia in fetal sheep using in utero EEG.
Methods
Near-term fetal sheep were subjected to progressive hypoxia induced by repeated umbilical cord occlusions (UCO) at increasing frequency. EEG changes during and between UCO were analysed visually and quantitatively, and related with gasometric and haemodynamic data.
Results
EEG signal was suppressed during occlusions and progressively slowed between occlusions with the increasing severity of the occlusions. Per-occlusion EEG suppression correlated with per-occlusion bradycardia and increased blood pressure, whereas EEG slowing and amplitude decreases correlated with arterial hypotension and respiratory acidosis.
Conclusion
The suppression of the EEG signal during cord occlusion in parallel with the cardiovascular adaptation appears to correspond to a rapid cerebral adaptation mechanism with a neuroprotective effect. The progressive alteration of the signal with the severity of the occlusions would reflect the cerebral hypoperfusion due to the failure of the cardiovascular adaptation mechanisms.

Abstract
Background
Postoperative delirium (POD) is considered as a relatively common and serious problem after major abdominal surgery procedures. It is presumed to be preventable in most of cases. The purpose of this study was to develop and evaluate a POD prediction model for patients undergoing abdominal surgery.
Methods
From July 2019 to December 2019, patients underwent elective abdominal surgery in our hospital were retrospectively analyzed, and their demographics, pre-operative evaluation, intra-operative and anesthesiologic factors were recorded. Based on the results of the multivariate regression analyzes using P < 0.05 and P < 0.001 as two significance level, we obtained 2 different prediction models comprising of 10 and 4 factors respectively. After factorizing the risk of overfitting and cross-validation, we proposed a final POD prediction model consisting of 4 predictors. From January 2021 to December 2021, 346 more qualifying patients were enrolled for the external validation of the 4-factor model. The study was retrospectively registered on the World Health Organization International Clinical Trials Registry Platform (WHO-ICTRP) with ID ChiCTR2100047405.
Results
After screening, 838 patients were included as the training cohort and 10.9% (91/838) of the patients manifested POD. Those patients who developed POD were more likely to be aged more than 60 years (OR = 1.345, P =0.005), with history of diazepam usage (OR = 3.622, P =0.003), history of cerebrovascular disease (OR = 2.150, P = 0.012) and intraoperative positive fluid balance (OR = 1.41, P <0 .001). The optimum cut-off point of the predicted probability that maximized the sum of sensitivity and specificity was 0.12. The fitting set AUC was 0.703 (95%CI: 0.637–0.753). The cross validation set AUC was 0.684 (SD = 0.068) and the external validation AUC of the model was 0.63 (95%CI: 0.511–0.758), quite closed to that of the fitting set, which indicated that the selected model was robust.
Conclusions
The 4-factor POD prediction model shows good prediction efficiency and can prompt for prophylactic intervention in patients at risk for POD.

Authors: Yin Chunran , Zhang Xiaojing 
Published: April 2023

Abstract
Building a livable rural environment is the main process to achieve rural revitalization. An ideal rural environment contains many factors, such as health, safety, convenience and comfort. On the basis of livability, it can also be transformed into a livable ecological environment by promoting harmony between man and nature, thus responding to the policies and calls for sustainable development. At present, the research on ecological and livable environment mainly focuses on environmental improvement and ecological regulation, thus neglecting the research on space environment itself. Under this background, this paper completes the optimization of rural environment public space by introducing data simulation technology and combining high-precision real-time digital images, and then uses HLA to design the system to complete the simulation. The system can receive the data and configuration parameter information of each subsystem, and also can apply the system entity data and information of both sides of space confrontation to complete the target processing. The system itself is mainly divided into three parts: visual display, visual representation and data analysis modules. It can effectively complete the population calculation, building area calculation, living area calculation and proportion analysis of the target rural areas, so as to facilitate decision-makers to conduct reasonable regulation on the design of public space environment by studying data characteristics. This paper analyzes the transformation of rural public space environment by combining data simulation technology with high-precision digital real-time images.

Published: April 2023

Abstract
Purpose: To investigate the association between transvaginal cervical length (TVCL) and delivery latency in pregnancies with preterm premature rupture of membranes (PPROM).
Methods: A prospective study was conducted with a total of 72 pregnancies diagnosed with PPROM between 24 and 34 weeks' gestation. Maternal characteristics, TVCL, time between diagnosis of PPROM and delivery, obstetric outcomes were documented. Multiple logistic regression was used to evaluate the independent prediction of significant parameters for delivery within 7 days. Patients were divided into two groups with a cutoff of 25 mm TVCL. The two groups were compared for maternal characteristics and neonatal outcome. Sensitivity, specificity, and predictive values were calculated for the combination of TVCL, presence of a cervical funneling and maternal BMI to show the predictive effect of the risk of delivery within 7 days
Results: Overall, 44% of the 72 PPROM cases delivered within the first 7 days after PPROM. The median gestational age at diagnosis of PPROM and median body mass index (BMI) were significantly higher in the group who delivered within 7 days after PPROM (p= 0.021, p=0.002, respectively). Presence of cervical funneling and short TVCL were associated with shorter latency (p= 0.001 and p=0.000). In logistic regression analysis, gestational week of PPROM and TVCL were found to be the parameters affecting the risk of delivery with a latency of ≤7 days. (OR =1.402, p=0.039; OR=0.46, p=0.045 respectively). The combination of < 25 mm TVCL and presence of cervical funneling had a sensitivity of 38% and a specificity of 97.5% in predicting latency ≤7 days with an accuracy of %71. The PPV was 92% and the NPV was 66%. When BMI was added to the combination, the PPV reached 100% in predicting latency ≤7 days with 18% sensitivity and 100% specificity.
Conclusion: Higher gestational age at diagnosis of PPROM and a short TVCL might help predict delivery within 7 days in pregnancies with PPROM. The combination of the presence of a cervical funneling, TVCL < 25 mm, and maternal obesity clearly demonstrated the potential for delivery within 7 days of PPROM. These findings may be useful for counseling and optimizing maternal and neonatal care in women with PPROM.

Published: April 2023

Abstract
In recent years, research on electrode materials of sodium-ion hybrid capacitors (SIHCs) that contain the advantages of batteries and capacitors have begun to emerge. And the transition metal oxides with high specific capacity that can be used as anodes for SIHCs have attracted great attention. Herein, one-step facile hydrothermal synthesis of the CoMoO4 nanorods as the transition metal oxides were successfully obtained. Due to the well bear to the volume change, the SIHCs exhibit superior electrochemical performance and stability with CoMoO4 nanorods anode during charge and discharge. At a current density of 0.05 A g-1, with an expanded potential from 0 to 3.0 V, the specific capacitance and the high energy density of CoMoO4//AC are 37.2 F g-1 and 63.3 Wh kg-1, respectively. Meanwhile, the stability of the CoMoO4//AC in the long cycle is as expected. After 6000 cycles, the capacity retention of the CoMoO4//AC SIHC is 90% while the coulombic efficiency is always around 99%.
Application of English education big data system based on multi-source information fusion and machine learning
Authors: DU Kehan 
Published: April 2023

Abstract
For administrators in the field of education, the data generated in the actual education process is difficult to achieve effective management due to its large amount of information, complex structure and multiple types. However, in the actual construction of education informatization, it is impossible to explore the laws and development trends of education information only by manual analysis, so it is difficult to obtain effective concepts and relevant views. College education administrators can not fully optimize the process of teaching diagnosis and reform through education informatization. Based on this background, this research introduces machine learning technology to achieve technical support for the integrated application of educational data. This paper focuses on the design and construction of an English teaching management data analysis system for college teaching, which combines machine learning technology with multi-source information technology. The system is mainly composed of hardware layer, data layer, service layer and application layer, which can assist teaching and realize learning career planning, faculty authority management, curriculum data modification, teaching resource allocation and scientific research review. The simulation results show that this big data system has high processing efficiency, and is superior to other algorithms in terms of mean value and FVDF extreme value, so it can effectively assist English teaching management. This paper completes the design of English education big data system by introducing machine learning and multi-source information fusion into the field of education.
Whole mitochondrial genomes reveal the relatedness of the browsing ant incursions in Australia

Published: April 2023

Abstract
Global trade and human movements outspread animal species, for example ants, from their native habitats to new areas. This causes biosecurity concerns because an exotic ant might have adverse impacts on agriculture, the environment, or health; thus, incurring economic losses. The browsing ant, Lepisiota frauenfeldi, was first detected in 2013 at the Perth Airport. Since then, more discrete browsing ant infestations have been found in Perth and at the Ports of Darwin and Brisbane. This exotic ant has been deemed a significant pest in Australia and eradication efforts are underway. However, tackling this invasion requires an understanding of how these infestations are related. Are they same or separate or a combination of both? Here, we carried out a phylogenetic analysis using high-throughput sequencing data to determine their relatedness. Our results showed that each interstate incursion was separate. Furthermore, the Western Australian incursions might have two introductions. These findings are critical in devising effective biosecurity measures. However, we discovered that this information could only be revealed by analysing the whole mitochondrial genome; not by a single mitochondrial gene as typically done for species identification. Here, we sequenced 51 whole mitogenomes including three of its congener L. incisa for the first time, for tracing future infestations.

Abstract
Background
Feed restriction occurs frequently during pig growth, either due to economic reasons or stressful environmental conditions. Local breeds are suggested to have better tolerance to periods of feed restriction. However, the mechanisms underlying the response to feed restriction in different breeds is largely unknown. The aims of the present study were 1) to compare the transcriptome profile in response to feed restriction and refeeding of two contrasted breeds, Large White (LW), which has been selected for high performance, and Creole (CR), which is adapted to tropical conditions, and 2) to investigate the effect of a moderate feed restriction and refeeding on whole blood transcriptome. Analysis of blood transcriptome allows to study the response to feed restriction and refeeding in a dynamic way. RNAseq was performed on blood samples of growing LW and CR pigs at two time points: after 3 weeks of feed restriction and after 3 weeks of refeeding. The data was compared with samples from control animals offered the same diet on an ad libitum basis throughout the whole experiment.
Results
In terms of performance (body weight and feed efficiency), CR pigs were less impacted by feed restriction than LW. The transcriptional response to feed restriction and refeeding between CR and LW was contrasted both in terms of number of DEGs and enriched pathways. CR demonstrated a stronger transcriptional response to feed restriction whereas LW had a stronger response to refeeding. Differences in the transcriptional response to feed restriction between CR and LW were related to cell stress response (Aldosterone Signalling, Protein ubiquitination, Unfolded Protein Signalling) whereas after refeeding, differences were linked to thermogenesis, metabolic pathways and cell proliferation (p38 MAPK, ERK/MAPK pathway). In both breeds, transcriptional changes related to the immune response were found after restriction and refeeding.
Conclusions
Altogether, the present study indicates that blood transcriptomics can be a useful tool to study differential genetic response to feed restriction in a dynamic way. The results indicate a differential response of blood gene expression to feed restriction and refeeding between breeds, affecting biological pathways that are in accordance with performance and thermoregulatory results.
