Published: March 2020

Aims: 1. To evaluate the applicability of The Expert Assessment (EA) based on the algorithm developed by the authors in performance assessment of transient elastography by M-probe (TE-M) and XL-probe (TE-XL), Fibrotest® (FT), shear wave elastography (SWE) and liver biopsy (LB) in fibrosis staging in chronic hepatitis C (CHC) patients in an approach without a «gold» standard; 2. To evaluate the quality of the proposed model (EA efficacy) in comparison with the results of the Rasch Model (MR) being an extension of the Latent Variable Analysis.Material and methods. Using the five studied diagnostic methods liver fibrosis staging was performed in chronic hepatitis C patients. Based on the algorithm developed EA was applied to each patient of the cohort and as a result fibrosis stage was established. That fibrosis stage considered a virtual reference. Sensitivity and specificity estimation as well as AUC calculation for studied methods was performed against the reference standard. The quality of the model (EA efficacy) estimated in the Rasch Model (MR) being an extension of the Latent Variable Analysis.Results. 99 patients with reliable results of each of the five diagnostic methods were included into the study. The main characteristics of the cohort were: 59.6% individuals of male gender, average age of 37 years (21–63), median BMI of 25.8 kg / m2. As per the results of the EA in detecting of mild fibrosis (F1), the values of AUC, sensitivity and specificity were, respectively: 0,972; 94,3; 91,3 for TE-M; 0,964; 90,6; 91,3 for TE-XL; 0,806; 81,1; 73,9 for FT; 0,907; 88,7; 71,7 for SWE; 0,832; 92,5; 37,0 for LB. In detecting of moderate fibrosis (F2), the appropriate values were: 0,981; 93,8; 94,0 for TE-M; 0,967; 90,6; 97,0 for TE-XL; 0,873; 75,0; 80,6 for FT; 0,957; 84,4; 91,0 for SWE; 0,937; 90,6; 94,0 for LB. In detecting of significant fibrosis (F3), the corresponding values were: 0,994; 95,5; 96,1 for TE-M; 0,987; 90,9; 97,4 for TE-XL; 0,870; 63,6; 84,4 for FT; 0,961; 86,4; 97,4 for SWE; 0,990; 90,9; 98,7 for LB. In detecting cirrhosis (F4), the appropriate values were: 0,995; 92,3; 97,7 for TE-M; 0,994; 100,0; 98,8 for TE-XL; 0,874; 38,5; 93,0 for FT; 0,996; 92,3; 100,0 for SWE; 0,964; 69,2; 100,0 for LB. The EA was shown to have high degree of consistency (correlation coefficient = 0,923; p <0,05) when compared to the MR.Conclusion. The EA was shown as a highly informative approach, applicable for performance assessment of the diagnostic methods for liver fibrosis staging without using LB as the “gold” standard. Non-invasive methods have demonstrated higher diagnostic characteristics with changing the standard from the traditional (LB) to virtual (EA). The high degree of consistency of the results of EA and MR confirm the high quality of the algorithm developed by the authors.

A novel hybrid Harris hawks-simulated annealing algorithm and RBF-based metamodel for design optimization of highway guardrails

Abstract
In this paper, a novel hybrid optimization algorithm is introduced by hybridizing a Harris hawks optimization algorithm(HHO) and simulated annealing for the purpose of accelerating its global convergence performance and optimizing structural design problems. This paper is the first research study in which the hybrid Harris hawks simulated annealing algorithm (HHOSA) is used for the optimization of design parameters for highway guardrail systems. The HHOSA is evaluated using the well-known benchmark problems such as the three-bar truss problem, cantilever beam problem, and welded beam problem. Finally, a guardrail system that has an H1 containment level as a case study is optimized to investigate the performance of the HHOSA. The guardrail systems are designed with different cross-sections and distances between the posts. TB11 and TB42 crash analyses are performed according to EN 1317 standards. Twenty-five different designs are evaluated considering weight, the guardrail working width, and the acceleration severity index (ASI). As a result of this research, the optimum design of a guardrail is obtained, which has a minimum weight and acceleration severity index value (ASI). The results show that the HHOSA is a highly effective approach for optimizing real-world design problems.
Impact strength of cemented implant interfaces

Published: March 2020

Abstract
Bone cement is a polymer used as filler material for the attachment of bone to implants in cemented joint replacements. Stronger interdigitation of the bone cement with both the implant and the bone provides a more durable surgical intervention. In previous studies published in the literature to date, tensile, shear and multi-axial stress occurring on the interfaced surfaces of the cement due to static and dynamic loads acting on the femur have been tested. This study investigated the impact strength of both implant-cement and cement-bone interfaces in a cemented implant. The effects of different implant materials, blasting sand particle size and cement mantle thickness on impact strength were investigated. It was determined that the surface roughness values of the implant materials increased as larger blasting sand particles were applied. As the surface roughness increased, the interfacial impact strength also increased. The impact strength of the cement-bone interface was higher than that of the implant-cement interface. The optimum mantle thickness in terms of impact strength was found to be 2 mm. Under impact force, failure will occur at the implant-bone cement interface.
Stress corrosion cracking of a high strength steel in organic salt drilling fluids

Abstract
Two round bar tensile samples (without notch and with notch) and two temperatures, namely 100 °C and 150 °C, have been used to observe the effect of notch and temperature on stress corrosion cracking in steel. The stress corrosion cracking sensitivity index of the tensile strength and elongation was calculated by means of data from a stress-strain curve. The fracture surface of the high strength steel was analyzed by scanning electron microscopy (SEM). In this way, the effect of notch and temperature on stress corrosion crack of the steel was determined. The results of a constant load tensile stress corrosion test show that at the same stress level and temperature, the stress corrosion cracking performance of an unnotched round bar tensile specimen was better than that of the notched specimen, and the unnotched steel had better corrosion resistance. Simultaneously, it was observed that the samples at 100 °C exhibited a lower stress corrosion cracking sensitivity index at the same stress level compared to the higher temperature (150 °C), which means that the steel showed a better corrosion resistance at a temperature of 100 °C. The fracture morphology analysis shows that the fracture surface of the unnotched round bar tensile samples had a dimple fracture, but the notched round bar tensile samples had a characteristic intergranular fracture due to the combined action of stress and the corrosive solution. Temperature increased the corrosion's velocity and the stress concentration in the notch causing an increase in dislocation after plastic deformation were the main reasons for the increase in stress corrosion sensitivity of the steel. It can be seen that these two factors, the temperature and the notch both increased the stress corrosion cracking sensitivity of the steel in organic salt drilling fluid, but the notch had a greater influence.

Published: March 2020

Trong kết cấu sàn-dầm nhà bê tông cốt thép, dầm biên thường chịu tác động xoắn gây ra bởi mô men âm của dầm phụ và sàn được đỡ bởi các dầm biên này. Trong hai tiêu chuẩn thiết kế hiện hành ACI 318-19 (Mỹ) và EN 1992-1-1 (Châu Âu), các tính toán dự báo sức kháng xoắn của dầm là tương đối khác nhau. Sự khác nhau này gây ra những khó khăn nhất định cho các kỹ sư thiết kế trong thực hành tính toán. Nghiên cứu này thực hiện so sánh công thức dự báo sức kháng xoắn của hai tiêu chuẩn trên đây, đồng thời so sánh các kết quả dự báo với kết quả thí nghiệm trên 2 mẫu dầm thực chịu tác động xoắn cho đến khi phá hoại hoàn toàn. Dựa trên các so sánh này, các khuyến cáo về quy trình tính toán thiết kế dầm biên chịu mô men xoắn sẽ được thảo luận.
