Sensitivity analysis of models of gas exchange for lung hyperpolarised 129-Xe MRS and MRI
Authors: Taylor Yohn , Wilson Frederick J , Kim Mina , Parker Geoff J M 
Published: July 2023

AbstractPurposeSensitivity analysis enables the identification of influential parameters and the optimisation of model composition. Such methods have not previously been applied systematically to models describing hyperpolarised129Xe gas exchange in the lung. Here, we evaluate current129Xe gas exchange models to assess their precision for identifying alterations in pulmonary-vascular function and lung microstructure.MethodsWe assess sensitivity using established univariate methods and scatter plots for parameter interactions. We apply them to the model described by Patz and MOXEet al., examining their ability to measure: i) importance (rank), ii) temporal dependence, and iii) interaction effects of each parameter across healthy and diseased ranges.ResultsThe univariate methods and scatter plot analyses demonstrate consistently similar results for the importance of parameters common to both models evaluated. Alveolar surface area to volume ratio is identified as the parameter to which model signals are most sensitive. The alveolar-capillary barrier thickness is identified as a low-sensitivity parameter for the MOXE model. An acquisition window of at least 200 ms effectively demonstrates model sensitivity to most parameters. Scatter plots reveal interaction effects in both models, impacting output variability and sensitivity.ConclusionOur sensitivity analysis ranks the parameters within the model described by Patzet aland within the MOXE model. The MOXE model shows low sensitivity to alveolar-capillary barrier thickness, highlighting the need for designing acquisition protocols optimised for the measurement of this parameter. The presence of parameter interaction effects highlights the requirement for care in interpreting model outputs.

AbstractHuman endometrial receptivity is a critical determinant of pregnancy success; however, in vivo studies of its features and regulation are particularly challenging due to ethical restriction. Recently, the development of human endometrial organoids has provided a powerful model to examine this intricate biological process. In this study, we established a specialized human window-of-implantation (WOI) endometrial organoid system that mimics the in vivo receptive endometrium. The endometrial organoid recapitulates not only the structural attributes of glands and stroma, but also the in vivo endometrium’s cell types at the single-cell level. Furthermore, the WOI endometrial organoid exhibits the features of in vivo implantation endometrium such as hormone responsiveness, secretory functions, and distinctive implantation window hallmarks, including decidualization, extracellular matrix (ECM) remodeling, pinopode formation, cilia generation and metabolism. This in vitro model also effectively demonstrates the process of proliferation-secretory transformation, ciliary epithelium differentiation, and epithelial-mesenchymal transition (EMT). As such, WOI organoids hold great promise as an alternative platform to unravel the intricate mechanisms governing endometrial receptivity regulation, maternal-fetal interactions, and associated diseases, ultimately driving impactful advancements in the field.
Experimental investigation of NACA 4415 airfoil using vibration data for stall detection
Authors: Ayaz Ümütlü Hatice Cansu , Kiral Zeki , Karadeniz Ziya Haktan 
Published: July 2023

Purpose
The purpose of this study is to identify the possible relation between the vibration and the stall by using the vibration response of the airfoil. For this purpose, the root mean square values of the acceleration signals are evaluated to demonstrate the compatibility between the stall angles and the vibration levels.

Design/methodology/approach
An experimental study is conducted on NACA 4415 airfoil at Reynolds numbers 69e3, 77e3 and 85e3. Experiments are performed from 0° to 25° of the angles of attack (AoA) for each Reynolds number condition. To observe the change of the vibration values at the stall region clearly, experiments are performed with the AoA ranging from 10° to 25° in 1° increments. Three acceleration sensors are used to obtain the vibration data.

Findings
The results show that the increase in the amplitude of the vibration is directly related to the decrease in lift. These findings indicate that this approach could be beneficial in detecting stall on airfoil-type structures.

Originality/value
This study proposes a new approach for detecting stall over the airfoil using the vibration data.

Authors: Chakraborty Santonab , Raut Rakesh D. , Rofin T.M. , Chakraborty Shankar 
Published: July 2023

PurposeIncreasing public consciousness and demand for sustainable environment make selection of a safe location for effective disposal of healthcare waste (HCW) a challenging issue. This problem becomes more complicated due to involvement of multiple decision makers having varying knowledge and interest, conflicting quantitative and qualitative evaluation criteria, and presence of several alternative locations.Design/methodology/approachTo efficiently resolve the problem, the past researchers have already coupled different multi-criteria decision-making tools with uncertainty models and criteria weight measurement techniques, which are time-consuming and highly computationally complex. Based on involvement of a group of experts expressing their opinions with respect to relative importance of criteria and performance of alternative locations against each criterion, this paper proposes application of ordinal priority approach (OPA) integrated with grey numbers to solve an HCW disposal location selection problem.FindingsThe grey OPA can simultaneously estimate weights of the experts, criteria and locations relieving the decision makers from complicated computational steps. The potentiality of grey OPA in solving an HCW disposal location selection problem is demonstrated here using an illustrative example consisting of three experts, six criteria and four alternative locations.Originality/valueThe derived results show that it can be employed to deal with real-time HCW disposal location selection problems in uncertain environment providing acceptable and robust decisions. It relieves the experts from pair-wise comparisons of criteria, normalization of data, identification of ideal and anti-ideal solutions, aggregation of information and so on, while arriving at the most consistent decision with minimum computational effort.

The context and concept of higher education for sustainable development: the case of Nepal
Authors: Adhikari Dev Raj , Shrestha Prakash 
Published: July 2023

Purpose
The purpose of this paper is to explore and analyze the context and concept of higher education for sustainable development (HESD) in Nepalese higher educational institutions (HEIs).

Design/methodology/approach
The research gathers facts and information both from primary and secondary sources. Five open-ended questions were developed to interview university high-ranking officials, such as VCs, registrars, deans and the chief of the planning division.

Findings
The inclusion of 17 sustainable development goals in the country’s Fifteenth Plan, national policy documents, and the University Grants Commission-led higher education reform programme provides sufficient context for HESD. In the absence of HESD literacy and a persuasive strategy, university leadership is less active in lobbying for SDG 4.7 with the government and funding agencies, university faculties and trade unions. In fact, both insights and initiatives to conceptualize HESD are lacking.

Research limitations/implications
This study’s setting is distinct and the interpretation of the HESD concept is based on a small sample size. Thus, the generalization of its findings is intrinsically limited in the context of a country in the geographic region. However, the findings of this research provide practical insights to implement HESD in Nepalese HEIs.

Practical implications
This study is intended to inform and prepare the Nepalese academic community, urging HEIs to implement HESD with a well-defined plan of action. It contributes to the literature by considering how the current context and concept of HESD suites to promote sustainability in Nepalese HEIs, transforming the traditional academic structure and making academic leaders aware that HESD is only a means to an end.

Originality/value
This research is Nepal’s first study of its type with a broad understanding of the context and concept of HESD. It also provides information for HEI leaders on how to initiate the HESD acceleration process.
Finite element analysis of stress field and fatigue life prediction of notched specimens under multiaxial load
Authors: Pan Xuemei , Liu Jianhui , Li Youtang , Hua Feilong , Chen Xiaochuang , Zhang Zhen 
Published: July 2023

PurposeThe stress state near the notch affects fatigue damage directly, but quantifying the stress field is difficult. The purpose of this study is to provide a mathematical description method of the stress field near the notch to achieve a reliable assessment of the fatigue life of notched specimens.Design/methodology/approachFirstly, the stress distribution of notched specimens of different materials and shapes under different stress levels is investigated, and a method for calculating the stress gradient impact factor is presented. Then, the newly defined stress gradient impact factor is used to describe the stress field near the notch, and an expression for the stress at any point along a specified path is developed. Furthermore, by combining the mathematical expressions for the stress field near the notch, a multiaxial fatigue life prediction model for notched shaft specimens is established based on the damage mechanics theory and closed solution method.FindingsThe stress gradient factor for notched specimens with higher stress concentration factors (V60-notch, V90-notch) varies to a certain extent when the external load and material change, but for notched specimens with relatively lower stress concentration factors (C-notch, U-notch, stepped shaft), the stress gradient factor hardly varies with the change in load and material, indicating that the shape of the notch has a greater influence on the stress gradient. It is also found that the effect of size on the stress gradient factor is not obvious for notched specimens with different shapes, there is an obvious positive correlation between the normal stress gradient factor and the normal stress concentration factor compared with the relationship between the shear stress gradient factor and the stress concentration factor. Moreover, the predicted results of the proposed model are in better agreement with the experimental results of five kinds of materials compared with the FS model, the SWT model, and the Manson–Coffin equation.Originality/valueIn this paper, a new stress gradient factor is defined based on the stress distribution of a smooth specimen. Then, a mathematical description of the stress field near the notch is provided, which contains the nominal stress, notch size, and stress concentration factor which is calculated by the finite element method (FEM). In addition, a multiaxial fatigue life prediction model for shaft specimens with different notch shapes is established with the newly established expressions based on the theory of damage mechanics and the closed solution method.
A method for the estimation of oil film parameters in an asymmetric rotor-bearing system
Authors: Chen Yinsi , Liu Yi , Li Yuan , Liu Heng 
Published: July 2023

Purpose
Asymmetric rotating machinery supported by oil film bearings is relatively common in practical applications. The purpose of this study is to propose a method for estimating the oil film parameters of the bearings in an asymmetric rotor-bearing system.

Design/methodology/approach
The proposed method requires the finite element model and translational displacement responses at the center of mass and bearings locations to form a regression equation to estimate the unknown parameters. Due to the transverse stiffness of the asymmetric rotor is not symmetrical, the analysis and parameter estimation procedures are performed in a rotating coordinate. Numerical simulations were carried out to illustrate the vibration characteristics of the asymmetric rotor system. The proposed method is applied to the simulated responses to estimate the assumed oil film parameters. The influence of the estimated parameter deviations on the rotor dynamic characteristics is discussed.

Findings
The vibration characteristics of asymmetric rotors are different from those of symmetrical rotors. The bearing parameters estimated by the proposed method are close to the assumed values, within a maximum error of 9%. The deviations of the estimated parameters have little effect on the vibration characteristic of the rotor system.

Originality/value
The proposed method does not require changing the rotational speed or applying additional excitation force to the rotor, which is suitable for the field test.

Published: July 2023

PurposeThe decision to select one amongst many choices of higher education institutions (HEIs) is a complex process. At a theory-building level, this study investigates the determinants of students' decisions as they consider investing in a long-term credence service higher education (HE) contract in pre- and in-pandemic and the implications for education managers. The second aspect is how disruptive global events influence such choice-making.Design/methodology/approachThe study hypothesized that there would be significant differences in the driving factors and their weight in students' decisions seeking admission into B-schools (Business schools). Structural equation modeling (SEM) and t-test validate the determinants and test hypothesized differences.FindingsResults reveal that core faculty quality, industry exposure, institutional brand name, placement offered, return on investment and specializations offered are the preferred choice criteria. The results reveal that choice criteria in the pre-and in-pandemic differ significantly.Originality/valueThe application of the SEM approach on a large primary database of students during the pre and in-pandemic periods to understand the changes in the choice of B-school for admission is the original aspect of the paper. Insights from the four hypotheses which got rejected provide value to stakeholders. As the pandemic is rearing its head once again across the globe, this study would be able to inform admissions managers on how to navigate for admissions success.

Authors: Crisan Emil Lucian , Chis Diana Maria , Bodea Eniko Elisabeta , Buchmann Robert 
Published: July 2023

PurposeThis paper reviews existing research to understand when, how and with what results robotic process automation (RPA) is implemented by organizations.Design/methodology/approachThe authors have identified 84 sources across eight databases and have analyzed them through the lens of a context–intervention–mechanism–outcomes framework (CIMO). The CIMO analysis maps the contextual drivers, intervention approaches and value related outcomes associated with RPA implementation.FindingsThe result of the analysis is the identification of four mechanisms explaining the approach organizations take to implement RPA: digitizing business processes, performing knowledge work together with humans, replacing outsourcing with RPA robots and developing a new business model. Therefore, in this paper, in order to reduce RPA literature fragmentation, the authors take into account the digital transformation (DT) perspective, by considering RPA as one example of digital technology.Practical implicationsThis study sensitize organizational adopters to the different mechanisms they can deploy to conduct RPA implementations to achieve different desired outcomes in response to different drivers. Moreover, having a clear picture of the key enablers and associated barriers to the realization of these alternative paths serve as a useful map to guide the implementation process.Originality/valueThe findings contribute to DT research by conceptualizing these mechanisms through which organizations deploy automation tools—such as RPA.
