Frequency Regulation of Nonlinear Power Systems using Neural Network Observer-Based Optimized Resilient Controller
Authors: Patel Vivek , Guha Dipayan , Purwar Shubhi
Published: July 2022

This study introduces a resilient frequency controller for nonlinear interconnected power systems to counteract endogenous/exogenous system disturbances. A neural network-based observer (NNO) is intended to estimate lumped system disturbances, such as unmodelled dynamics and unknown disturbances. The estimated NNO’s output is incorporated with a second-order sliding mode controller (SOSMC) to minimize chattering in the control effort and improve the nominal performance of the undertaken plant. The design parameters of SOSMC have been optimally identified by applying Harris hawk optimization (HHO), exercising integral error-based objective function. HHO has demonstrated superior tuning capabilities than other well-known optimization methodologies in terms of convergence rate and transient measurements of system outputs. The asymptotic convergence of estimated error and overall stability of the system has been established employing the Lyapunov argument. System outputs are compared with the results reported in the literature to validate the efficacy of the proposed resilient frequency controller. Presented results showcase the mastery of the applied NNO-based SOSMC over its counterparts in weaker chattering, fast disturbance rejection, and a high degree of robustness against endogenous/exogenous disturbances.

Authors: Huang Ying , Chen Hong
Published: July 2022

The influence of the nursing safety management in nursing quality of hemodialysis room was deeply analyzed through the evaluation index study of nursing quality in hemodialysis room. Sixty-two patients were selected from hemodialysis rooms as study samples, and 31 patients who had not carried out nursing safety management from September 2018 to September 2019 were selected as control samples. Thirty-one patients who underwent nursing safety management from September 2019 to September 2020 were included in the observation group. By comparing the samples of the control group and the observation group, it was found that the comprehensive score of adverse reaction risk nursing quality and nursing satisfaction score between the groups were significantly improved; P < 0.05. Nursing safety management can effectively reduce the quality of nursing in hemodialysis room and greatly reduce the occurrence of adverse risks.

Authors: Kalaiyarasi M. , Rajaguru Harikumar
Published: July 2022

The most common gynecologic cancer, behind cervical and uterine, is ovarian cancer. Ovarian cancer is a severe concern for women. Abnormal cells form and spread throughout the body. Ovarian cancer microarray data can diagnose and prognosis. Typically, ovarian cancer microarray data contains tens of thousands of genes. In order to reduce computational complexity, selecting the most critical genes or attributes in the entire dataset is necessary. Because microarray datasets have limited samples and many characteristics, classifier detection lags. So, dimensionality reduction measures are essential to protect disease classification genes. In this research, initially the ANOVA method is used for gene selection and then two clustering‐based and three transform‐based feature extraction methods, namely, Fuzzy C Means, Softmax Discriminant Algorithm (SDA), Hilbert Transform, Fast Fourier Transform (FFT), and Discrete Cosine Transform (DCT), respectively, are used to select relevant genes further. Six classifiers further classify the features as normal and abnormal. The NLR classifier gives the highest accuracy for SDA features at 92%, and KNN gives the lowest accuracy of 55% for SDA, Hilbert, and DCT features. With correlation distance feature selection, the NLR classifier attains the lowest accuracy of 53%, and the highest accuracy of 88% is obtained by the GMM classifier.

In Ethiopia, some plants (Ethiopia kale, Swiss chard, and celery) remain underutilized for human consumption, as information on their nutritional potential remains limited. As a result, the purpose of this study was to determine the proximate, mineral, antinutrient, and phytochemical content of Ethiopia kale (Brassica carinata), Swiss chard (Beta vulgaris), carrot (Daucus carota), tomato (Lycopersicon esculentum), and cabbage (Brassica oleracea) using standard analytical methods. The moisture, crude protein, crude fiber, crude fat, total ash, total carbohydrate, and energy contents were found to be 6.44–16.62%, 6.76–33.64%, 9.19–54.86%, 0.50–4.00%, 1.00–2.75%, 7.28–68.73%, and 141.06–333.28 kcal/100 g, respectively. Ethiopia's kale had a high protein content, while celery had a high fat and fiber content. The calcium, magnesium, iron, phosphorous, potassium, zinc, and sodium content (mg/100 gdb) ranged between 8.00 and 306.00, 8.10–11.83, 0.64–4.85, 11.34–63.00, 2.83–810.00, 0.15–41.65, and 1.50–443.80 mg/100 g, respectively. Swiss chard contained magnesium, potassium, and sodium, whereas celery was high in calcium and iron. The total oxalate, condensed tannin, and phytate (mg/100 gdb) ranged as follows: 0.88–4.92, 138.27–892.19, and 69.14–265.99, respectively. Ethiopia’s kale recorded a comparatively low amount of tannin and phytate. High mineral bioavailability, such as calcium, iron, and zinc, was obtained in Ethiopia kale. The results also showed that Ethiopia's kale contained a good amount of total phenolic and flavonoid content. The findings indicated that Ethiopia kale was a significant source of protein, had low antinutrient content with high mineral bioavailability, and had the potential to formulate nutrient-rich infant and young child foods using staple cereals and pulse grains.

Published: July 2022

Malignant pleural mesothelioma (MPM), a fatal tumor, is mainly linked to the asbestos exposure. It has been reported that together with the inhalation of asbestos fibers, other factors are involved in the MPM onset, including simian virus 40 (SV40). SV40, a polyomavirus with oncogenic potential, induces (i) in vitro the mesenchymal cell transformation, whereas (ii) in vivo the MPM onset in experimental animals. The association between MPM and SV40 in humans remains to be elucidated. Sera (n = 415) from MPM-affected patients (MPM cohort 1; n = 152) and healthy subjects (HSs, n = 263) were investigated for their immunoglobulin G (IgG) against simian virus 40 large tumor antigen (Tag), which is the transforming protein. Sera were investigated with an indirect enzyme-linked immunosorbent assay (ELISA) using two synthetic peptides from SV40 Tag protein. SV40 Tag protein was evaluated by immunohistochemical (IHC) staining on MPM samples (MPM cohort 2; n = 20). Formalin-fixed and paraffin-embedded (FFPE) samples were obtained from MPM patients unrelated to MPM serum donors. The proportion of sera, from MPM patients, showing antibodies against SV40 Tag (34%) was significantly higher compared to HSs (20%) (odds ratio 2.049, CI 95% 1.32–3.224;

p
=
0.0026

). Immunohistochemical staining (IHS) assays showed SV40 Tag expression in 8/20, 40% of MPM specimens. These results indicate that SV40 is linked to a large fraction of MPM. It is worth noting that the prevalence of SV40 Tag antibodies detected in sera from cohort 1 of MPM patients is similar to the prevalence of SV40 Tag found to be expressed in FFPE tissues from MPM cohort 2.

Published: July 2022

Digital technology is so broad today as to encompass almost everything. It eases the difficulties of day-to day life with internet. E-commerce plays an important role in digital age of technology. Instead of many benefits of online system, it faces many types of threats. Sometime, choosing the best e-commerce security has a lot of uncertainties and ambiguities to reduce the effect of threats. To reduce these uncertainties, this article developed a new concept of complex cubic picture fuzzy set (CoCPFS) of fuzzy algebra that explains the positive effect, neutral effect, and negative effect of any object and additionally discussed the Cartesian product between two CoCPFSs, CoCPF relations, and their types. The relationship among the e-commerce securities and threats is investigated for the first time in the history of fuzzy algebra. These relations show the ways of disabling the effects of a threat by an effective security technique. Furthermore, the advantages and benefits of CoCPFS are explained through comparison tests with preexisting frameworks of fuzzy sets.

Published: July 2022

This work was to investigate mechanism by which mir-22 targeting nod-like receptor protein 3 (NLRP3) inflammasome affected activity of human skin malignant melanoma (MM) A375 cells. Twenty-four mice were rolled into a control group (Group X) and an experimental group (Group Y) randomly. Without treatment in Group X, Group Y established MM model. After cell transfection, the mice were divided into group A (blank group), group B (negative group), group C (miR-22 mimics group), group D (miR-22 inhibitor group), and group E (miR-22 inhibitor+siNLRP3 group). The results were summarized as follows. The level of miR-22 mRNA in Group Y was obviously lower than that in Group X, and levels of NLRP3 and caspase-1 mRNA and NLRP3 and caspase-1 protein in Group Y were greatly higher than those in Group X (

P
<
0.05

). The mRNA levels of miR-22 mRNA in group C were much higher in contrast to those in group A, and the mRNA levels of NLRP3 and caspase-1 were lower. The contrast results in group D and group A were the opposite,

P
<
0.05

. The levels of NLRP3 and caspase-1 proteins in group C were greatly elevated, and those in group D were decreased compared with those in group A (

P

0.05

). Therefore, miR-22 may target and inhibit the activation of the NLRP3 inflammasome to reduce the activity of cutaneous malignant melanoma A375 cells.

Published: July 2022

Background. In our clinical practice, conventional radial access has been employed routinely for coronary procedures. The distal radial artery (DRA) access site has recently emerged as a novel technique in cardiac procedures. Objectives. This study compares distal radial access to standard forearm radial access (FRA) in terms of feasibility, outcomes, and complications. Method. This prospective, randomized trial was conducted at a single center. The patients were chosen from An-Najah National University Hospital’s catheterization laboratory between December 2019 and November 2020. A total of 209 patients were randomized into two groups: DRA group (n = 104) and FRA group (n = 105). Results. Access was successful in 98% of patients in both the groups. The DRA group had a longer puncture duration and a higher number of attempts (duration: 56.6 ± 61.1 s DRA vs. 20.0 ± 18.4 s FRA,

p
<
0.001

, attempts: 1.9 ± 1.3 DRA vs. 1.2 ± 0.60 FRA,

p
<
0.001

). Puncture-associated pain was greater in the DRA group (4 ± 2.2 DRA vs. 3 ± 2.1 FRA,

p
=
0.001

). There were two radial artery occlusions in the FRA group and none in the DRA group (

p
=
0.139

). Percutaneous coronary intervention (PCI) was performed in 26% of the DRA group and 37.1% of the FRA group. The DRA group had significantly shorter procedure times (

p
=
0.006

), fluoroscopy times (

p
=
0.002

), and hemostasis times (

p
=
0.002

). Over time, the learning curve demonstrated improved puncture duration and a decrease in the number of puncture attempts. Conclusions. DRA is a safe and practical alternative to FRA for coronary angiography and intervention. The overtime learning curve is expected to improve puncture-related outcomes.

Published: July 2022

Objective. To evaluate the feasibility of reducing the injection velocity and volume of contrast agent according to BMI, and the effect of body weight (BW), body surface area（BSA）, body mass index（BMI），and blood volume (BV) on aortic contrast enhancement when the voltage of third‐generation dual‐source CT is selected at 70 KV. Methods. A total of 280 patients selected at 70 KV were randomly divided into an experimental group and a control group. Each group was divided into 7 subgroups according to BMI ≤20, 20–21, 21‐22, 22‐23, 23‐24, 24‐25, and 25–26. The experimental group uses 2.3/2.4/2.5/2.6/2.7/2.8/2.9 ml/s injection speed with 350 mgI/ml contrast agents according to the subgroups; injection time was fixed at 10 s. In the control group, the fixed injection flow rate was 3.5 ml/s, time was 12 s with a total of 42 ml. Subjects in both groups were inspected to adaptive prospective ECG‐gating sequence scanning, and subjective and objective image quality of the two groups were compared using Student's t‐test. BMI, BSA, and BV were calculated from the patient’s body weight and height. We assess the relationship between aortic attenuation and BW, BMI, BV, and BSA using regression analysis or correlation analysis. Results. Significant differences exist in vascular enhancement between the two groups; SNR and CNR of objective image quality in the experimental group were lower than those in the control group (P < 0.05). Both groups had the same subjective image scores (P > 0.05). The number of vessels in the optimal enhancement range counts more in the experimental group than in the control group (χ2 value = 334.25, P ＜ 0.05). In the control group, a weak to medium correlation was seen between vascular enhancement and BMI (r = −0.20), BW (r = −0.42), BSA (r = −0.46), and BV (r = −0.48) (P ＜ 0.05 for all). Conclusions. Compared to BW, BSA, and BV, a weaker negative correlation exists between vascular enhancement and BMI when ATVS selects 70 KV. However, as a much easier way to operate, the stepped low flow and low‐contrast agent injection based on BMI was feasible, and the image quality was more homogenized than that of the control group.
A Nonlinear Controller for Neutral Point Piloted (T-Type) Multilevel Inverter-Based Three-Phase Four-Wire DSTATCOM
Authors: Swetha K. , Sivachidambaranathan V.
Published: July 2022

In recent times, neutral point piloted (NPP) or half-leg T-type multilevel inverter (MLI) becomes a promising topology for medium-voltage high-power applications. This T-type MLI is the best substitute for diode clamped multilevel inverter (DCMLI) due to its simple structure and absence of clamping diodes. However, the neutral point voltage control or dc bus capacitors' balance of NPP T-type MLI is a challenging task. Therefore, this paper presents a nonlinear sliding mode controller (SMC) for dc-link voltage balance and reference current control in distribution static compensator (DSTATCOM). For this, a three-level T-type MLI-based three-phase four-wire DSTATCOM is considered to eliminate current-related power quality issues such as harmonics, reactive power, load unbalance, and neutral current. The proposed NPP T-type-based DSTATCOM is compared with DCMLI and active DCMLI-based DSTATCOMs in terms of switching losses and cost. Simulation studies are carried out in MATLAB Simulink environment and further corroborated with experimental studies. Furthermore, the ability of the proposed SMC-based controller is compared with the PI controller under different operating conditions.

Published: July 2022

To investigate the prognostic potential of serum aldehyde dehydrogenase isoform 1 (ALDH1) level in acute cerebral infarction, and the molecular mechanism in mediating neurological deficits, a total of 120 acute cerebral infarction cases within 72 h of onset were retrospectively analyzed. Serum ALDH1 level in them was detected by qRT‐PCR. Receiver operating characteristic (ROC) and Kaplan–Meier curves were depicted for assessing the diagnostic and prognostic potentials of ALDH1 in acute cerebral infarction, respectively. An in vivo acute cerebral infarction model in rats was established by performing MCAO, followed by evaluation of neurological deficits using mNSS and detection of relative levels of ALDH1, Smad2, Smad4, and p21 in rat brain tissues. Pearson’s correlation test was carried out to verify the correlation between ALDH1 and mNSS and relative levels of Smad2, Smad4, and p21. Serum ALDH1 level increased in acute cerebral infarction patients. A high level of ALDH1 predicted a poor prognosis of acute cerebral infarction patients. In addition, ALDH1 was sensitive and specific in distinguishing acute cerebral infarction cases, presenting a certain diagnostic potential. mNSS was remarkably higher in acute cerebral infarction rats than that of controls. Compared with sham operation group, relative levels of ALDH1, Smad2, and Smad4 were higher in brain tissues of modeling rats, whilst p21 level was lower. ALDH1 level in brain tissues of modeling rats was positively correlated to mNSS, and mRNA levels of Smad2 and Smad4, but negatively correlated to p21 level. Serum ALDH1 level is a promising prognostic and diagnostic factor of acute cerebral infarction, which is correlated to 90‐day mortality. Increased level of ALDH1 in the brain of cerebral infarction rats is closely linked to neurological function, which is associated with the small mothers against decapentaplegic (Smad) signaling and p21.

Published: July 2022

The rising need for lightweight and strong mechanical structures has contributed significantly towards the development of CNT macrostructures; however, the interplay of parameters and their discontinuous synthesis have obstructed their delivery to commercial level. Herein, floating catalyst chemical vapor deposition technique (FC‐CVD) has been employed for the fabrication of 90 cm long CNT sheet via continuous production of CNT aerogel. High degree of graphitization, thermal stability and purity have been indicated by Raman spectroscopy (IG/ID = 10.03), thermogravimetric analysis, and SEM studies. Continuous winding of CNT aerogel has increased the alignment into the sample which resulted into high electrical conductivity value of 21400 S/m. Furthermore, the alignment has been quantified by calculating optical anisotropic ratio via polarized Raman technique and conductivity anisotropic ratio κ‖ /κ⊥ which were calculated to be 4.63 and 3.4, respectively, and show reasonable agreement. These findings indicate that a well correlation of synthesis parameters results in highly aligned CNT sheet structure in a single step.

Published: July 2022

Relying on expert diagnosis, it solves the problem of fan failure efficiency and meets the needs of automatic inspection and intelligent operation monitoring of fans. In order to make up for the deficiency of intelligent diagnosis of bearing fault based on vibration signal detection, signal transformation, and convolution neural network identification and improve the ability of intelligent diagnosis, this study designs a deep convolution neural network model and diagnosis algorithm with three pairs of convolution pooling layers and two full connection layers. The experimental verification of the proposed method is carried out based on the public data set, and the effects of three different signal transformation methods based on vibration signal through vibration gray map, short-time Fourier transform time-frequency map, and continuous wavelet transform time-frequency map on the accuracy of diagnosis model are compared and analyzed. A very accurate guarantee is received, close to 100%. The final experimental results demonstrate the effectiveness of the information on the accuracy of diagnostic testing and provide new ideas for the verification and testing of wind turbine wind energy. Compared with other machine learning algorithms, the real-time recognition of machine learning based on time-domain statistical features is lower than that of convolutional neural network methods. The effect of the scale of the trained model on the accuracy of the algorithm is discussed. A sample ratio of 50% and 70% was found to be appropriate.

Authors: Yang Yongle , Dong Xiyuan , Bai Jian , Jin Lei , Huang Bo
Published: July 2022

The aim of this study was to assess the relationship between early developmental kinetics and the competence to result in a live birth as well as the impact of maternal age and the number of retrieved oocytes. This retrospective cohort study included 3,021 single‐embryo transfer cycles and assessed live birth outcomes paired with morphokinetic data; 1,412 transfers resulted in live births (LB), and 1,609 did not (NLB). Early morphokinetic parameters between LB and NLB embryos were compared from patients stratified into four age groups (20‐25, 26‐30, 31‐36, and ≥37 years) and between embryos in the same competence groups within the age groups. Early morphokinetic parameters were also compared between LB and NLB embryos from patients stratified into four groups based on the number of oocytes harvested (≤7, 8‐14, 15‐21, and ≥22). The association between morphokinetic parameters and LB was tested using univariate and multivariate analyses. This study indicated that embryos resulting in LB generally exhibit faster developmental dynamic parameters than embryos that do not. However, this difference decreased in the younger (20‐25 years) and older (≥37 years) age groups. In addition, when the number of harvested oocytes was low (≤7) or high (≥22), this difference was less obvious. The morphokinetic parameters of embryonic cleavage are an effective reference value for embryo selection strategies aimed at increasing live birth rates, especially for patients aged 26–36 years, with 8–21 harvested oocytes.

Authors: Wongthongsiri Supawat , Hirose Sohichi
Published: July 2022

This paper investigates the scattering behavior of guided shear horizontal (SH) waves in a two-dimensional, isotropic, and linear elastic layered plate with partially debonded interface by analyzing the reflection and transmission coefficients of scattered waves. The partial wave technique is established to form the displacement and stress of guided wave functions, and the boundary element method (BEM) is utilized to handle the numerical calculation with elastodynamic fundamental solutions in the frequency domain. After applying proper boundary conditions including continuity condition on the interface with traction-free debonding, the scattering coefficients can be obtained in terms of boundary element solutions. Two different materials (steel and aluminum) with various debonding lengths and locations in a 1 mm double-layered plate are considered. With several modes of the incident wave over a frequency range up to 4.5 MHz, the variations of scattering coefficients and scattering phenomena are numerically investigated as several parameters such as mode of the incident wave, materials, locations, and length of debonding are changed. The numerical results also suggest the potential of the suitable wave mode for the debonding detection, which can be useful for non-destructive inspection.

Objective. To investigate the effect of annular external fixator-assisted bone transport in the treatment of traumatic massive bone defect of tibia on clinical healing, pain stress, and joint function. Methods. From January 2018 to November 2021, 146 patients with traumatic massive bone defect of tibia were selected as the research objects, and they were divided into observation group (annular external fixator-assisted bone transport, 71 cases) and control group (unilateral external fixator bone lengthening, 75 cases) according to different surgical methods. The therapeutic efficacy, fracture healing-related indexes, and postoperative range of motion of the knee joint were compared between the two groups. Callus healing was evaluated by Fernandez-Esteve callus score, and joint function was evaluated by Paley score, American Knee society score (AKSS), and Baird-Jackson ankle score. The changes of pain mediator (serum substance P (SP), neuropeptide Y (NPY), prostaglandin E2 (PGE2), and tumor necrosis factor-α (TNF-α)) and stress indexes (adrenocorticotropic hormone (ACTH), cortisol (COR), and nor Epinephrine (NE)) were observed before and after treatment in two groups. The incidence of postoperative complications was analyzed. Results. There were no significant differences in total effective rate and bone lengthening between the two groups (

P
>
0.05

). The bone healing time and callus formation time in the observation group were shorter than those in the control group, and the Fernandez-Esteve callus score was higher than that in the control group (

P
<
0.05

). The levels of SP, NPY, PGE2, TNF-α, ACTH, COR, and NE in the observation group were lower than those in the control group (

P
<
0.05

). AKSS and Baird-Jackson scores in the observation group after operation were higher than those in the control group (

P
<
0.05

). There was no significant difference in the incidence of postoperative complications between the two groups (

P

An Analysis of Antinuclear Thought in William Golding’s Literary Works from the Perspective of Ecoenvironmental Psychology: Taking “Lord of the Flies” as an Example
Authors: Jiang Kanshuai
Published: July 2022

In “Lord of the Flies,” William Golding integrates the living conditions of human beings into the relationship of the community of destiny between man and nature and reveals the neglect of ecological morality in the modern Western ethical value system with modernity as the core, showing a postmodern ecological ethics consciousness beyond modernity. The novel embodies the ecological integrity of the nonbinary opposition between man and nature, criticizes anthropocentrism and technological rationality that destroy the ecological integrity, and points out that modern science and technology have led to greater ecological disasters due to the lack of ecological ethics. Ecological morality that respects nature and the harmonious coexistence of man and nature is advocated. The forward‐looking ecological ethics consciousness contained in the novel is especially thought‐provoking in today’s serious ecological problems and lack of ecological ethics. This paper will use ecological psychology as a new interdisciplinary research field to study the relationship between man and nature and open up new horizons and research methods. In this way, we will solve the growing ecological and environmental crisis.

Authors: Xu Minming , Ouyang Yun
Published: July 2022

It is well known that flooding brings great losses to people’s production and life, just because it is unsuspected, is extremely extensive, and has high frequency. More than half of the people in China live in flood-prone areas, and their lives and properties are threatened. Flood risk assessment is one of the measures of flood management, and it is economically and socially important to assess flood risk. The scope of the traditional monitoring and forecasting early warning system is mainly limited to the area affected by flash floods, while the objective reality of real-time monitoring, forecasting, and early warning of flood disasters in the area affected by river floods and by the scheduling of riverine terrace power stations is not possible. The multiphysics remote sensing big data fusion analysis can divide the data into grids according to the grid method in the sliding time window, filter the normal data by information entropy in each grid, judge the remaining data that may be abnormal by using local abnormality factor, and eliminate the abnormal data according to the judgment result. This paper introduces the application of remote sensing in flood control field, proposes the framework of basin flood prediction based on multiphysics field remote sensing big data fusion analysis, and designs each functional module of the system according to the object-oriented idea to realize the functions of data management, image processing, spatial analysis, and simulation output. The method can change the problems of cumbersome data processing and basic parameter rate determination in traditional hydrological methods and can find certain regularity through the connection between all related factors. Meanwhile, the use of artificial intelligence and other technical means makes the calculation speed faster and the obtained results are closer to the actual measured values, which is beneficial to guide the practical work.

Authors: Wang Chaoyi
Published: July 2022

To assess students’ learning efficiency under different teaching modes, we used students’ facial expressions in the classroom as a study point. An enhanced generative adversarial network is presented. We designed a generator as an automatic coding-decoding combination in a cascade structure with a discriminator configuration. It can retain different expression intensity features to the maximum extent. We also added a new auxiliary classifier, which can classify different intensity features and improve the model’s recognition of detailed features of similar expressions, thus improving the comprehensive facial expression recognition accuracy. Our approach has a great advantage over the other facial expression recognition approaches on public datasets. Finally, we conduct experimental validation on the self-made student facial expression dataset in all cases. The experimental findings showed that our approach’s recognition accuracy is superior to that of other methods, demonstrating the method’s efficacy.
A Big Data Technique for Internet Financial Risk Control
Authors: Xie Hengxin , Shi Yufeng
Published: July 2022

The danger of losing funds on an investment or business enterprise is referred to as financial risk. Credit risk, liquidity risk, and operational risk are some of the most prevalent and different financial hazards. Financial risk control is an organizational activity that seeks to detect, monitor, and manage exposure to different risks associated with the usage of financial services. Conventional accounting risk control has relatively great timeliness and unpredictability; therefore, traditional accounting risk identification has numerous difficulties, such as high error rate, low precision, lengthy time, and risk. As a result, this research provides a unique financial risk control strategy in the Internet environment based on big data. First, the decision tree algorithm is used to classify the users who can face financial risks. Simultaneously, the user’s personal credit information is established and represented mathematically, and the 5C mathematical model is obtained. In this way, the user’s credit degree can be judged more accurately, and the user’s credit rating can be obtained, allowing quantitative analysis of users to be realized. Second, construct and weight the financial risk system index of the Internet in accordance with the existing financial system. Finally, the Internet financial risk control model based on big data is built, and the financial risk early warning threshold range is determined to achieve Internet financial risk control. The experimental findings reveal that the method’s risk identification error rate is minimal, accuracy is high, and control time is quick. It can match the actual risk level, which shows that the control effect of this method is good.

Objective. To explore the effect of mosaic allograft osteochondral transplantation combined with corrective osteotomy in treating osteochondral lesions of the talus (OLT) on ankle and knee joint function and lower limb alignment. Methods. One hundred and thirty-three OLT patients treated in our hospital between July 2015 and October 2019 were enrolled. Regarding the various surgical approaches, they were categorized into two groups, namely, A and B including 69 and 64 cases, respectively. The patients in group A were processed with mosaic allograft osteochondral transplantation combined with corrective osteotomy, and the patients in group B were processed with microfracture surgery. The Baird ankle function score and visual analog scale (VAS) were employed for evaluating the surgical efficacy and the degree of pain prior to and following surgery. The pre- and postoperative surgery-related indicators, Ankle Hindfoot Scale (AOOFAS), HSS score, lower limb alignment, and range of motion of the ankle were compared between the two groups, and changes in growth factor levels prior to and following processing were observed. Results. Overall scores were better in group A than in group B (

P
<
0.05

). The operation length was longer in group A, the amount of intraoperative blood loss was greater, and the length of hospitalization was less than in group B. The VAS score 48 hours after surgery was also lower (

P
<
0.05

). Postoperative AOFAS scores in group A were better, and lower limb alignment was also less than in group B (

P
<
0.05

). The postoperative HSS score did not differ significantly between the two groups (

P
>
0.05

). The range of plantar flexion and dorsiflexion of the ankle joint was better in group A, and the levels of endothelial growth factor (VEGF), platelet-derived growth factor (PDG), and transforming growth factor β1 (TGF-β1) were lower than those in group B (

P
<
0.05

). The occurrence of postoperative problems did not differ between the groups (

P
>
0.05

). Conclusion. Mosaic allograft osteochondral transplantation combined with corrective osteotomy has a high effective rate in the treatment of OLT, which can promote the healing of articular cartilage and the recovery of ankle joint functions, improve the range of motions of the ankle, and improve the lower limb alignment.
The Mediating Role of Depression and Pain Catastrophizing in the Relationship between Functional Capacity and Pain Intensity in Patients with Fibromyalgia
Authors: Montoro Casandra I. , Galvez-Sánchez Carmen M.
Published: July 2022

Background. Fibromyalgia syndrome (FMS) is a chronic musculoskeletal pain condition characterized by widespread pain, sleep problems (i.e., insomnia and unrefreshing sleep), fatigue, cognitive, and emotional difficulties. Although pain has been proposed the factor mostly impacting in the FMS patients’ function, emotional and psychological FMS-associated factors are also known to exert a negative impact in quality of life and functional capacity. Nonetheless, the relationship between these factors and functional limitations in FMS patients is considered to be complex and not clearly defined. Therefore, the present study is aimed at assessing the associations between FMS functional capacity, FMS symptoms (pain, fatigue, insomnia, depression, and state and trait anxiety), and associated psychological factors such as pain catastrophizing, as well as the possible mediating role of these latter in the relationship between pain and FMS functional capacity. Method. 115 women diagnoses with FMS completed a set of self-administered questionnaires to evaluate the clinical and psychological variables of the study. Results. FMS functional capacity was positively associated with the majority of FMS symptoms except state anxiety. Regression analyses confirmed a greater prediction for FMS functional capacity by depression, fatigue, and pain catastrophizing, in this sequence. Both, pain catastrophizing and depression were important factors mediating the association between clinical pain (total and intensity) and FMS functional capacity. Conclusions. Findings support a key role of pain catastrophizing and depression in the disability associated to pain in FMS. Treatment goals directed to lessen depression and pain catastrophizing levels should be promoted to reduce the impact of pain in FMS patients’ daily function.

Published: July 2022

Chinese wheat-based foods have a long history and a wide range of varieties, which is representative of Chinese food culture. Pasta and bread are made of wheat flour, and the characteristics of pasta and bread are closely related to the quality of wheat flour. The quality of wheat is mainly affected by environmental conditions, and different varieties of wheat are suitable for planting in different regions, so the regionalization of wheat is formed. Due to the different quality of wheat and eating habits in different regions of China, the same kind of wheat-based foods has different flavors in different regions, such as steamed bread, noodles, and stuffed buns. The regional characteristics of food are also formed between different regions. For example, Naan. With the changes in Chinese people’s eating habits and consumption level, there are more and more types of wheat-based foods, which are developing in the direction of industrialization. This review clarifies the wheat planting regionalization in China, giving an insight into the relationship between different wheat quality and the variety of traditional wheat-based foods, describing the types and regional distribution of traditional wheat-based food products in China. Moreover, the types of wheat-based foods are classified and whose characteristics are introduced, and the consumption trend of wheat-based foods in China is elaborated.

An Assessment of Kwasi Wiredu’s Consensual Democracy: Towards a More Viable Alternative Political System
Authors: Adeyanju Olanshile Muideen
Published: July 2022

This paper undertakes a critical examination of Kwasi Wiredu’s argument for a non-party consensual democracy in contemporary African societies. Wiredu advocates for this as an alternative to majoritarian democracy which, he argues, shuts out the interests and aspirations of the minority and breeds political instability. The paper argues that the non-party consensual democracy does not fit into the complex needs of contemporary African societies. The paper also admits that majoritarian democracy, as it is currently practised in most African societies, is inadequate in achieving the socio-political ideals of a democratic setting. However, the paper maintains that majoritarian democracy has the features, which are lacking in non-party consensual democracy, that can be modified, broadened and developed to achieve the democratic ideals that can help address the challenges of contemporary African societies. Thus, outside the strict choice between a return to non-party consensual democracy and the currently-practised majoritarian democracy, the paper proposes a broadened but modified model of the majoritarian form of democracy which has roots in majoritarian democracy but differs on the grounds of its substantial incorporation of democratic standards lacking in majoritarian democracy.
Progressive failure analysis and taguchi-based optimisation of filament-wound composite tubes subjected to internal pressure using continuum damage mechanics approach

Published: July 2022

In this paper, a hybrid utilisation of the continuum damage mechanics approach and some novel techniques was employed for progressive failure analysis of internally pressurised filament-wound composite tubes. The constructed numerical model in Abaqus software, which is employed for prediction of functional and burst failure of the tubes, was validated with an experimental failure evaluation available in the literature. Results show the high accuracy and precision of the proposed model. Therefore, this model can be used as a cost-effective virtual failure exam prior to experimental tests or as their alternative. Then, this validated model has been used in the second part of this paper for optimisation. Due to some drawbacks of the previous optimisation methods, by using the Taguchi approach capabilities, a novel strategy is proposed for optimisation of the stacking sequence of tubes under various stress ratios with taking into account the manufacturing winding angle restrictions. Results reveal that the obtained optimal stacking sequences are asymmetric and highly dependent on calculation strategies and applied stress ratio.
Income Inequality and Population Health: Examining the Role of Social Policy
Authors: McFarland Michael J. , Hill Terrence D. , Montez Jennifer Karas
Published: July 2022

Studies of the relationship between income inequality and life expectancy often speculate about the role of policy, but direct empirical research is limited. Drawing on the neo-materialist perspective, we examine whether the longitudinal association between income inequality and life expectancy is mediated and moderated by policy liberalism in U.S. states (2000–2014). More liberal policy contexts are characterized by greater efforts to regulate the economy, redistribute income, and protect vulnerable groups and lesser efforts to penalize deviant social behavior. We find that state-level income inequality is inversely associated with policy liberalism and life expectancy. The association between income inequality and life expectancy was not mediated by policy liberalism but was moderated by it. The association is attenuated in states with more liberal policy contexts, supporting the neo-materialist perspective. This finding illustrates how states like New York and California (with liberal policy contexts) can exhibit high income inequality and high life expectancy.
