Published: July 2023

AbstractThis paper proposes moving horizon estimation (MHE) to estimate the state variables of autonomous vehicle linear systems under measurement noises. To solve the MHE optimization problem, quadratic programming is employed. The steering angle, yaw angle, and global position constraints of an autonomous vehicle are considered in the estimation design. According to the simulation results, it can be observed that although the longer MHE step can give better results compared to the shorter MHE step, the difference in the MHE step only slightly affects the estimated results. However, the longer MHE step can increase the computational time. Additionally, the proposed MHE scheme is compared to the Kalman filter (KF) estimator. Based on the obtained results, the KF gives a better estimation than the MHE, but this notion must be verified for other case studies.Keywords: autonomous vehicle; Kalman filter; linear system; MHE; quadratic programming. AbstrakPaper ini mengusulkan moving horizon estimation (MHE) untuk mengestimasi variabel keadaan sistem linier kendaraan otonom karena pengaruh noise pengukuran. Untuk menyelesaikan masalah optimasi MHE, digunakan pemrograman kuadratik. Kendala sudut kemudi, sudut yaw dan posisi global dari kendaraan otonom dipertimbangkan dalam desain estimasi. Dari hasil simulasi dapat diketahui bahwa meskipun langkah MHE yang lebih panjang dapat memberikan hasil yang lebih baik dibandingkan dengan langkah MHE yang lebih pendek, perbedaan langkah MHE hanya sedikit mempengaruhi hasil estimasi. Namun, langkah MHE yang semakin panjang dapat meningkatkan waktu komputasi. Selain itu, skema MHE yang diusulkan dibandingkan dengan estimator Kalman filter (KF). Berdasarkan hasil yang diperoleh, KF memberikan estimasi yang lebih baik daripada MHE, tetapi gagasan ini harus diverifikasi untuk studi kasus lainnya.Kata Kunci: kendaraan otonom; Kalman filter; sistem linier; MHE; pemrograman kuadratik. 2020MSC: 62P35, 65D19

AbstractIn this paper, a new three-parameter distribution, which is a member of the Alpha Power Transformed Family of distributions, is introduced. The new distribution is a generalization of the logistic model called the alpha power transformed logistic (APTL) distribution. Some mathematical properties of the new distribution like moments, quantile function, median, skewness, kurtosis, Rényi entropy, and order statistics are discussed. The parameters of the distribution are estimated using the maximum likelihood estimation method and a simulation study is performed to investigate the effectiveness of the estimates. The usefulness and flexibility of the APTL distribution in modelling financial data are investigated using two portfolio stock indices, namely the NASDAQ and New York stock indices, both from the United States stock market. Based on the model selection criteria, we are able to establish empirically that the APTL distribution is the best for modelling the two data sets, among the various distributions compared in the study. For each of the data, the quantile value-at-risk estimates for the APTL distribution give the smaller expected portfolio loss at high confidence levels in comparison to those of the other distributions.Keywords: Alpha power transformed family of distributions; logistic distribution; maximum likelihood estimation; portfolio investments; value-at-risk.

AbstractIn this article, polymer-modified concrete was studied to present the effect of using additives on its mechanical properties. This will be achieved by employing a high-performance super plasticizing admixture that significantly enhances polymer-modified concrete mechanical capabilities. The study indicates that the polymer styrene-butadiene rubber (used increases concrete mechanical properties by 10% by weight. When the dosage exceeds 10% by weight of cement, the compressive, tensile, and flexural strengths of polymer-modified concrete are diminished. With the addition of a superplasticizer with a ratio of 1.2%, regular polymer-modified concrete compressive strength has increased from 34.3 to 42.9 MPa for a 10% polymer/cement ratio. Additionally, this superplasticizer enhanced the Material's flexural and tensile strength.

Published: July 2023

Background: Treatment of skin allergic diseases remains a challenging research topic.
Objective: To investigate the effect of Kushen recipe extractive (KS) gel on contact dermatitis (CD) of mouse.
Methods: Allergic contact dermatitis (ACD) model of mouse was established. Immunohistochemical method (ICH) and flow cytometry method (FCM) were used to detect CD4+ and CD8+ T lymphocytes and explore the regulation effect of KS on the immune status of the organism. The expression status of eotaxin tissue was evaluated by real-time polymerase chain reaction (RT-PCR), ICH, and western blotting method. The survival rates of HaCaT cell and Fibroblasts affected by KS were detected by methyl thiazolyl tetrazolium (MTT) method. The inhibitory effect of KS on eotaxin produced by HaCaT cell and FBs induced by TNF-α and interleukin (IL)-4 were evaluated using RT-PCR and enzyme-linked immunosorbent assay methods. The inhibitory effect of KS on nuclear factor-κB (NF-κB) and Signal transducers and activators of transcription 6 (STAT6) activation induced by TNF-α and IL-4 was detected by electrophoretic mobility shift assay and western blotting methods.
Results: We confirmed that KS shows favorable therapeutic effect on CD, which can obviously inhibit eotaxin expression and Eosinophils recruitment in allergic skin of mouse, as well as regulate the immune status of the organism. Furthermore, KS and its main effective components can inhibit TNF-α and IL-4 induced upregulation of eotaxin via the two signal transduction pathways, NF-κB and STAT6.
Conclusions: The great importance of traditional Chinese recipe KS is evidenced by its therapeutic effect and mechanism in ACD of mouse.
FoxO4 mediates macrophage M2 polarization by promoting LXA4R expression in an ovalbumin-induced allergic asthma model in mice
Authors: Yu Tong , Yu Yiping , Ma Yingyu , Chen Guoqing 
Published: July 2023

Background: Asthma imposes a heavy burden due to its high prevalence. Forkhead box O4 (FoxO4) proteins participate in the modulation of cell progression. However, the role and mechanism of FoxO4 in asthma remains uncharted.
Methods: An allergic asthma model was constructed by the induction of ovalbumin and interleukin (IL)-4 in mice and monocyte/macrophage-like Raw264.7 cells, respectively. The role and mechanism of FoxO4 in asthma was determined by pathological staining, immunofluorescence assay, measurement of inflammatory cells in the blood, reverse transcription quantitative polymerase chain reaction (RT-qPCR), Western blot analysis, and flow cytometry.
Results: Ovalbumin treatment triggered an obvious inflammatory cell infiltration with a prominent increase in F4/80+ cell numbers. The relative messenger RNA (mRNA) and protein expressions of FoxO4 were increased in both ovalbumin-induced mice and interleukin-4 (IL-4)-induced Raw264.7 cells. Inhibition of FoxO4 via AS1842856 reduced inflammatory cell infiltration, the number of Periodic Acid Schiff+ (PAS+) goblet cells, the numbers of inflammatory cells in the blood, and the airway resistance in ovalbumin-induced mice. Besides, interference of FoxO4 decreased the number of F4/80+CD206+ cells, and the relative protein expressions of CD163 and Arg1 in vivo and in vitro. Mechanically, suppression of FoxO4 diminished the relative mRNA and protein expressions of LXA4R in both ovalbumin-induced mice and IL-4-induced Raw264.7 cells. Overexpression of LXA4R reversed the outcomes caused by repression of FoxO4, including airway resistance, the number of F4/80+ cells, the proportion of CD206+ cells in ovalbumin-induced mice, and the proportion of F4/80+CD206+ cells in IL-4-induced Raw264.7 cells.
Conclusion: FoxO4/LXA4R axis mediated macrophage M2 polarization in allergic asthma.
Circulating Pentraxin-3 and its association with C-reactive protein levels and disease activity in patients with chronic spontaneous urticaria
Authors: Beyaz Şengül , Belkaya Serkan , Öztop Nida 
Published: July 2023

Introduction: Pentraxin-3 (PTX3) is a soluble long pentraxin molecule that regulates inflammatory responses. This study aimed to determine the plasma levels of plasma PTX-3 as an inflammation marker in chronic spontaneous urticaria (CSU) and whether the PTX3 levels correlate with disease activity and other clinical parameters, including acute phase reactants and biomarkers.
Methods: The study included 70 CSU patients and 30 healthy controls. Plasma PTX3 levels were measured by ELISA. CSU disease activity was evaluated with the urticaria activity score summed over 7 days. Complete blood count, C-reactive protein (CRP), transaminases, total IgE, antinuclear antibody, anti-thyroid peroxidase, anti-thyroglobulin, and D-dimer levels were recorded.
Results: Of the 70 patients, 52 (74.3%) were female, with a mean age of 37.51 ± 11.80 years. Disease activity was severe in 43, moderate in 15, and mild in 12 patients. Mean PTX3 levels were elevated in CSU patients compared to healthy controls (0.81 vs. 0.55 ng/mL, p = 0.031). The mean CRP levels were higher in patients than in the controls (4.26 vs. 1.57 mg/L, p = 0.023). Patients also had higher D-dimer levels than the controls (5.96 vs. 0.59 mg/L, p < 0.001). A significant positive correlation was found between PTX3 and CRP levels (r = 0.508, p < 0.001) and between D-dimer levels and UAS7 (r = 0.338, p = 0.004) and CRP (r = 0.213, p = 0.034) levels. A multivariable stepwise regression analysis showed that the one-unit increase in the CRP level increased to 38.19 units in the PTX3 level (95% confidence interval [17.40–58.98], p < 0.001).
Conclusion: Circulating levels of CRP and PTX3, two members of the pentraxin family, are significantly correlated and elevated in CSU patients with increasing disease activity, indicating their utility as inflammatory markers in CSU.

Intriduction. Hibernomas account for less than 2 % of all benign lipomatous tumors and 1 % of all lipomatous tumors. They are usually found in 20–40-year old adults (the average age of patients is 38 years). The clinical manifestations are painless soft tissue mass that are mostly slow growing; rapid growth is only found in a small number of patients. We present a case of successful surgical treatment of a pathologically confirmed rare lipomatous tumor of large size, which was located in the soft tissues of the thigh.Clinical case. A 46-year-old woman was admitted to the hospital due to a tumor 20 × 10 × 10 cm in size, that had developed 10 years ago in the anteromedial aspect of the proximal thigh. Furthermore, she had a history of hypoesthesia one month prior to her admission. During surgery, the femoral nerve was found to be compressed by the large tumor. The resultant symptoms probably caused the patient to seek medical care. Resection was performed by careful dissection, femoral nerve and vessels were spared. Histopathological examination and cytogenetics showed findings suggestive of a hibernoma. At the 6-month follow-up local tumor recurrence or metastasis was not found.Conclusions. Asymptomatic small-sized hibernoma does not require surgical resection or other treatment. When the tumor is too large and/or has the potential to compress the surrounding tissues, timely radical surgical intervention is reuired.

Hyperhomocysteinemia is a condition characterized by elevated levels of homocysteine in the blood, which has been linked to various cardiovascular and renal complications, including impaired renal function. , a widely used medicinal herb, has been shown to possess antioxidant, anti-inflammatory, and vasoprotective properties. However, its potential role in improving renal function in hyperhomocysteinemic conditions remains largely unexplored. Hyperhomocysteinemia is a metabolic disorder characterized by elevated levels of homocysteine in the blood, which is associated with impaired renal function. This study aimed to investigate the potential therapeutic effects of Panax Ginseng on renal function in hyperhomocysteinemic rats. Male Wistar rats There were five animals per group. Group 1 functioned as the control group, receiving a typical meal (chow feed) and unlimited water. L-methionine (1.7 g/kg/day, p.o.) was given to group 2 Hyperhomocysteinemia (HHCY Control) once daily. A modest dosage of Panax ginseng (50 mg/kg body weight) and L-methionine (1.7 g/kg/day, p.o.) was administered orally to the third group (test drug 1). The fourth group (test drug 2) got the same combination of L-methionine (1.7 g/kg/day, p.o.) and Panax ginseng (high dosage, 100 mg/kg body weight). In addition, the second, third, and fourth groups of rats received intraperitoneal doxorubicin injections at a dosage of 5 mg/kg after 1 hour of L-methionine administration at intervals of 15 days in order to produce Hyperhomocysteinemia-mediated nephrotoxicity. After 28 days of the trial, the animals were slaughtered, and the blood levels of homocysteine, creatinine, and urea were measured. We measured the amounts of urea, creatinine, and homocysteine in the serum. administration effectively improved renal function and attenuated histopathological changes in hyperhomocysteinemic rats. These findings suggest that Panax Ginseng may have a renoprotective effect in Hyperhomocysteinemia-induced renal dysfunction.
