Published: February 2021

AbstractIn the present study, the lipid amount and fatty acid profile of different Sparidae species, including gilthead seabream, juvenile gilthead seabream, annular seabream, white seabream, common two‐banded seabream were evaluated. Fish were seasonally collected from Köyceğiz Lagoon (Muğla, South Western Turkey) from June 2018 to June 2019 and after collection, the sex of each specimen was recorded. According to the results of the study, the highest lipid amount was found in female annular seabream individuals as 8.09 ± 0.78% in November and the lowest lipid amount was found in male juvenile gilthead seabream as 0.98 ± 0.12% in March. Palmitic acid and oleic acid were determined as the most abundant SFA and MUFA for all species, respectively. The highest value of DHA, which was the predominant PUFA was assessed as 15.33 ± 0.26% in female white seabream in November whereas the lowest value (3.83 ± 0.36%) was found in gilthead seabream in December. The n‐6/n‐3 ratio was determined between 0.27 ± 0.00 (for male common two‐banded seabream in July)‐1.20 ± 0.03 (for male gilthead seabream in December) and it followed within the range of healthy values for all species. As a conclusion, it was found that values of lipid and fatty acid profiles among the examined Sparidae species vary among the season of collection. The results of the study gave the seasonal nutritional values of four economically‐important Sparidae species that being rich in healthy polyunsaturated fatty acids such as DHA, have beneficial in human nutrition.

AbstractA sensitive intensity modulation differential optical fiber angular displacement sensor has been developed. The influence of the distance between the end face of the emitting fiber and the reflecting surface, the tilt angle of receiving optical fiber and the surface reflectivity on the performance of the sensor was analyzed. The optimal geometric parameters of the sensor structure were obtained based on the simulation results and the response of the sensor to different angular displacement was investigated. The experimental results show the sensor has large linear range for micro angular displacement detection and the sensitivity can reach to 0.0377 V/° and 0.08104 V/° for positive and negative angle detection respectively.

PurposeProvide a direct, non‐invasive diagnostic measure of microscopic tissue texture in the size scale between tens of microns and the much larger scale measurable by clinical imaging. This paper presents a method and data demonstrating the ability to measure these microscopic pathologic tissue textures (histology) in the presence of subject motion in an MR scanner. This size range is vital to diagnosing a wide range of diseases.Theory/MethodsMR micro‐Texture (MRµT) resolves these textures by a combination of measuring a targeted set of k‐values to characterize texture—as in diffraction analysis of materials, performing a selective internal excitation to isolate a volume of interest (VOI), applying a high k‐value phase encode to the excited spins in the VOI, and acquiring each individual k‐value data point in a single excitation—providing motion immunity and extended acquisition time for maximizing signal‐to‐noise ratio. Additional k‐value measurements from the same tissue can be made to characterize the tissue texture in the VOI—there is no need for these additional measurements to be spatially coherent as there is no image to be reconstructed. This method was applied to phantoms and tissue specimens including human prostate tissue.ResultsData demonstrating resolution <50 µm, motion immunity, and clearly differentiating between normal and cancerous tissue textures are presented.ConclusionThe data reveal textural differences not resolvable by standard MR imaging. As MRµT is a pulse sequence, it is directly translatable to MRI scanners currently in clinical practice to meet the need for further improvement in cancer imaging.
Experimental, analytical, and finite element assessment of the shear strength of concrete‐rock interfaces at different scales
Authors: Renaud Sylvain , Bouaanani Najib , Miquel Benjamin 
Published: February 2021

AbstractThis paper presents an original analytical approach to assess the shear strength of concrete‐rock interfaces while accounting for the effects of scale, roughness and matching conditions. The technique proposed is based on experimental data obtained from small core samples extracted from existing dam sites, with diameters varying from 83 to 145 mm, and larger rectangular samples with side lengths comprised between 320 and 492 mm. The predictions of the analytical formulation are validated against results of direct shear tests, as well as 3D nonlinear finite element simulations. Sensitivity analyses are conducted to evaluate the influence of roughness and matching conditions on the shear behavior of concrete‐rock contacts at different scales. The main results show that: (i) roughness inhomogeneity is one of the main causes of scale effects on the shear strength of concrete‐rock interfaces; (ii) contact geometries proportional in both length and height are expected to present quite similar shear strengths; and (iii) geometry matching conditions must be accounted for as they might be the source of scale effects affecting the evaluation of the shear strength at concrete‐rock interfaces. New equations are also proposed to suggest values of apparent cohesion and friction angle for concrete‐rock contacts.
Superwettability‐based separation: From oil/water separation to polymer/water separation and bubble/water separation
Authors: Yong Jiale , Yang Qing , Huo Jinglan , Hou Xun , Chen Feng 
Published: February 2021

AbstractThe separation of oil/water mixtures, polymer/water mixtures, or bubble/water mixtures has broad applications. In this paper, we aim at extending the well‐developed wettability‐based oil/water separation strategy to separate the mixtures of liquid polymers and water and separate bubbles from water. The micro/nanostructures are simply produced on a stainless steel mesh by femtosecond laser treatment to endow the mesh with superhydrophilicity in the air and superoleophobicity, superpolymphobicity, and superaerophobicity in water. The underwater superoleophobicity, superpolymphobicity, and superaerophobicity enable the structured mesh to have the ability of oil/water separation, polymer/water separation, and bubble/water separation. Water can pass through the mesh due to the superhydrophilicity of the laser‐structured mesh. Whereas, the oils, the liquid polymers, and the bubbles in water are intercepted by the structured mesh because such a water‐wetted mesh has strong repellence to oils (underwater superoleophobicity), liquid polymers (underwater superpolymphobicity), and bubbles (underwater superaerophobicity). As a result, the oil, the liquid polymer, and the bubble are successfully separated from water by using the as‐prepared superwetting mesh. We believe that the diversified wettability‐based separation processes will have wide potential applications in environmental protection, energy utilization, industrial manufacture, agricultural production, and so on.

Stochastic analysis of an age‐dependent mixture truncation model
Authors: Kayid Mohamed , Alrubian Anfal , Abouammoh Abdulrahman 
Published: February 2021

AbstractIn this article, a new mixture model is introduced to model randomly left truncated data. The likelihood ratio ordering of original random variable and resultant random variable in the model is established. It is shown that the increasing failure rate (IFR) property of the original random variable translates into the IFR property of the resultant random variable under an ordering property. In addition, the resultant random variable in the random truncation model is proved to be less than the resultant random variable in our model with respect to the likelihood ratio order. Possible extensions of the model to the multivariate case are considered. Finally, the model is applied to model the upper record values of a sequence of random variables and as another application the lifetime of a unit under burn‐in process is scrutinized.
Numerical solution of additive manufacturing problems using a two‐level method
Authors: Viguerie Alex , Auricchio Ferdinando 
Published: February 2021

AbstractAdditive manufacturing techniques have grown significantly in recent years due to their ability to produce designs almost impossible to obtain with standard production technologies. This growth has in turn led to increased demand for numerical simulation of additive processes. Unfortunately, such simulations are difficult from the computational point of view, since additive problems are characterized by the presence of highly local nonlinearities requiring fine mesh resolutions on small portions of the domain. These difficulties are compounded by the fact that such regions of local high nonlinearities move in the domain with time, and further, by the fact that the physical domain itself evolves with time. Accordingly, the present article addresses these complex computational issues by employing a two‐level technique. The two‐level method provides a natural framework for the resolution of localized nonlinearities while avoiding the need for complex meshing operations, such as refinement‐and‐derefinement algorithms. The proposed approach is validated on a series of one‐ and two‐dimensional problems to establish the viability of the introduced two‐level method for additive manufacturing problems.

AbstractAimThe study aimed to explore the association between diabetes‐related distress as a dependent variable and fear of hypoglycaemia as a independent variable in Chinese individuals with type 2 diabetes, which can provide a basis for the development of effective nursing interventions.DesignA cross‐sectional descriptive study.MethodsPre‐piloted scales were used to determine whether they experienced fear of hypoglycaemia and whether this impacted upon their management of the disease. From June–October 2019, participants were asked to complete the “hypoglycaemia fear survey” and “diabetes distress scales” to assess levels of fear and distress. Stepwise multivariate regression analysis was applied to reveal relationship between distress as a dependent variable and fear as a independent variable. Covariates included demographic, clinical or lifestyle factors.ResultsA total of 258 participants were recruited for the survey, and they were characterized by little or no distress (39.53%), moderate distress (45.35%) and high distress (15.12%). The prevalence of moderate to severe distress in patients was 60.47%. Increased diabetes‐related distress was strongly correlated with increased fear of hypoglycaemia and closely associated with the scores of the worry and behaviour subscales. These results indicated that 62.3% of diabetes‐related distress may be explained by fear of hypoglycaemia.ConclusionIncreased diabetes‐related distress is associated with increased fear of hypoglycaemia in individuals with type 2 diabetes.

Optimal H2 filtering for measurement‐delay systems with multiplicative noise and sampled data
Authors: Wang Wei , Han Chunyan , Wang Xiaohong 
Published: February 2021

AbstractThis paper is concerned with the optimal H2 filtering problem for continuous‐time systems with multiplicative noise and multiple sampled delay measurements. The reorganized observation technique is firstly applied for treating the sampled delay terms, and then an equivalent delay‐free sampled measurement is received. An optimal H2 filter is constructed by using a dynamic model with finite jumps, which can provide the state estimation of the measurement sampling interval as well as the measurement sampling moments. The filter gain is given in terms of the stabilizing solution to a set of specific Riccati differential equations. It should be pointed out that no state augmentation is required, and thus the Riccati equation developed in this paper remain the same dimension as that of the original system state. This is the clear distinction from the state augmentation method. A practical example is finally supplied to illustrate the efficiency of the proposed results.

Published: February 2021

Abstract

Background
Both protracted irinotecan and antiangiogenesis therapy have shown promising efficacy against Ewing sarcoma (EWS).

Methods
Patients diagnosed with recurrent or refractory EWS were enrolled and further categorized into cohort A (≥16 years) or cohort B (&lt;16 years). In the dose-defining phase Ib portion, anlotinib was given daily at a fixed dose, while a 3+3 design with dose de-escalation was used to determine the dose of irinotecan. The next dose-expanding phase II portion employed a conventional two-stage study design model. The primary endpoint was objective response rate at 12 weeks (ORR12w).

Results
A total of 41 patients finally received the treatment regimen, including 29 in cohort A and 12 in cohort B. For cohort A, the first five patients were treated at the initial level of 20 mg/m2/d d × 5 × 2, and two of them subsequently a dose-limiting toxicity (DLT). An additional six patients were then treated at 15 mg/m2 without any DLT, and the RP2D was determined. Notably, 23 out of 24 patients in cohort A were available for response evaluation at 12 weeks. ORR12w was determined to be 62.5%. For cohort B, no DLT was observed in the first six patients at the initial dose level. At last, 12 patients were included in cohort B. The ORR12w was 83.3%. The most frequently observed grade 3/4 adverse events were leukopenia (28.5%), neutropenia (24.4%), anemia (8.7%), and diarrhea (3.7%).

Conclusion
The combination of vincristine, irinotecan, and anlotinib demonstrated an acceptable toxicity profile and promising clinical efficacy in patients with advanced EWS.

Implications for Practice
This is the first trial to evaluate an irinotecan-based regimen in combination with antiangiogenesis tyrosine kinase inhibitors in Ewing sarcoma (EWS). A 3+3 design with dose de-escalation was used to determine the most appropriate dose of irinotecan in each cohort. The next dose-expanding phase II portion employed a conventional two-stage study design model. The objective response rate was 62.5% for adults and 83.3% for children. Median overall survival was not matured. This study shows that the combination of vincristine, irinotecan, and anlotinib demonstrates an acceptable toxicity profile and promising clinical efficacy in patients with advanced EWS.

Published: February 2021

AbstractIn this investigation, hemp fibers were‐surface treated by ethylene polymerization grafting to determine the effect of high grafting level on the mechanical (tensile and impact) and dynamic mechanical properties of linear medium‐density polyethylene (L) composites (20%wt.) produced via melt compounding. The results showed that, comparing the treated hemp composite (L20PH) with the untreated hemp composite (L20H), the modification reduced by 44% the modified fibers composite water absorption, while increasing the elongation and tensile strength by about 197% and 14%, respectively. Moreover, due to better interfacial interactions with the matrix and the flexibility imparted by the presence of both grafted and ungrafted polyethylene (PE) onto modified hemp fibers, the corresponding composite exhibited lower density and significantly high impact resistance (about 57%) compared to the untreated hemp composite. These results were confirmed by the composites creep strain as L20PH and L maximum strain (εmax) was respectively 18% and 42% higher compared to that of L20H, showing that L20H has the high modulus followed by L20PH and then L. The significant improvement of the modified composite flexibility, impact resistance and the limited reduction of its modulus make this material not only suitable for building and construction applications, but also in the production of packaging and automotive parts.

Published: February 2021

AbstractStyrene butyl acrylate (SBA) copolymer latex nanoparticles which contain vinyltrimethoxysilane as binding agent were prepared using microemulsion polymerization and were used for coating sisal fiber. The structure of SBA and coated sisal fiber (CF) was confirmed by Fourier transform infrared spectroscopy. The effect of the surface coating of sisal fiber (SF) on the SF/natural rubber (NR) composite properties was systematically evaluated through curing characteristics, morphological properties, mechanical properties, water absorption resistance, biodegradability and dynamic mechanical analysis. As indicated from the morphological study, the coating of SF with SBA enhanced the interfacial adhesion between SF and the NR matrix. In addition, the tensile strength was improved by 26.9% and 43% after the addition of 5 and 10 phr (parts per hundred rubber), respectively, of CF to NR. The coating process improved the water resistance of SF/NR composite significantly especially at high SF loading level, where the composite that contained 30 phr CF absorbed 6.7% water compared to 13.2% for the composite containing uncoated sisal fiber (UF). Dynamic mechanical analysis confirmed that the coating process improved the interfacial adhesion between the SF and NR matrix as indicated from the higher values of storage modulus and lower values of maximum loss factor (tan δmax) recorded for composites containing CF compared to those containing UF. © 2021 Society of Industrial Chemistry.
