A metadata model for authenticity in digital archival descriptions
Authors: Pacheco André , Da Silva Carlos Guardado , De Freitas Maria Cristina Vieira 
Published: July 2023

AbstractThe advent of the information paradigm has shaken many of the principles of archival theory and practice. One key issue is knowing to which extent can digital information be trusted. Digital resources are represented by metadata, and trust consists in demonstrating their authenticity. Since the traditional elements used to verify the authenticity of analog records are not suitable in the digital world, the field faces a major challenge. The use of abundant, pertinent and constantly captured metadata seems to one of the most relevant solutions. This article aims to contribute to tackle this issue by setting the goal of proposing a model that attempts to include the most relevant metadata elements to capture the information that contributes for ascertaining the authenticity of digital archival descriptions. To that end, mixed methods methodology are employed. A qualitative documentary research is used to collect, analyze and interpret a corpus of scientific literature. As a complement, the quantitative technique requirements engineering is used to extract from international description standards the metadata requirements that can assist in the presumption of authenticity. Both approaches are then combined through a critical lens into a single unifying model for authenticity that is deemed as complete as necessary but as simple as possible. The model can be used by organizations or as a contribution to the discussion of authenticity and trustworthiness in digital archival descriptions.
Cultivating criticality in a neoliberal system: a case study of an English literature curriculum at a mega distance university
Authors: Knoetze Retha 
Published: July 2023

AbstractNeoliberal practices such as managerialism and academic casualisation impact higher education systems globally. While these practices can constrain any curriculum aimed at enabling transformative learning, this paper shows that they place particular limitations on arts and humanities curricula intent on cultivating criticality and a sense of social responsibility. I draw on data from an English literature curriculum study at a mega distance education institution in South Africa and use Legitimation Code Theory to take a close-up look at how two neoliberal practices: managerialism and academic casualisation cause misalignments between the underpinning values of the curriculum and the kinds of pedagogic and formative assessment practices that are employed. I conclude that decisions regarding administration, enrolments and staffing based on neoliberal values can frustrate students’ epistemological and ontological access to humanities disciplines and limit the potential of humanities curricula to offer a higher education in service of the social good.

Abstract
Purpose
The Impact of Weight on Self-perception Questionnaire (IW-SP) is a three-item patient-reported outcome measure (PROM) instrument assessing the impact of body weight on self-perception. To date no published threshold for meaningful change exists. The objective of this study was to estimate the minimal important change (MIC) for the IW-SP among people with type 2 diabetes.

Methods
Responder analyses were conducted using anchor- and distribution-based approaches with existing clinical trial data (SURPASS-2). As SURPASS-2 did not include a priori anchors, a set of alternative exploratory anchors were identified based on the MICs and items from two conceptually related measures used in the trial as well as percent change in body weight. Exploratory anchors with change estimates that were sufficiently related to change in IW-SP (r ≥ 0.30) and were not redundant with other anchors were retained for the MIC analyses. The analyses were conducted in two stages (estimation = 2/3 of sample) to derive initial IW-SP MIC estimates, and a subsequent confirmation stage (remaining 1/3 of sample).

Results
While the most conceptually related anchors and items performed best in responsiveness analyses, all anchors resulted in a similar estimate of minimal meaningful change for the IW-SP total score: a 1-point change in raw units (1–5-point scale), corresponding to a 25-point change for transformed scores (0–100 scale). Distribution-based analyses supported these MIC estimates. Results were similar across both stages for all analyses.

Conclusion
The MIC for the IW-SP for patients with T2D is a 25-point change on the transformed score.

Published: July 2023

AbstractMultiple sclerosis (MS) is an autoimmune, demyelinating disorder of the central nervous system (CNS) affecting approximately 2.5 million people worldwide. The mechanisms underlying the pathogenesis of MS are still only partially elucidated. Galectins are a family of β-galactoside-binding lectins that are involved in the regulation of immune and inflammatory responses and have been shown to exert a role in the maintenance of central nervous system (CNS) homeostasis. There has been an increasing interest in the role of galectin-3 in neuroinflammation and neurodegeneration. In the current study, we have evaluated the expression levels of galectin-3 in different cellular populations involved in the etiopathogenesis of MS. We have observed dramatically higher transcriptomic levels of galectin-3 in encephalitogenic CD4+ T cells in a preclinical model of MS, the MOG-induced experimental allergic encephalomyelitis (EAE). Also, significantly higher levels of galectin-3 were found in microglial cells, astrocytes, and oligodendrocytes isolated from the spinal cord of EAE mice, as well as in human MS-related white matter lesions. Modular co-expression analysis revealed that galectin-3 is co-expressed with genes involved in the regulation of microglia, cytokine production, and chemotaxis. This is the first comprehensive analysis of the expression of galectin-3 in MS, further strengthening its potential pathogenetic role in the etiopathogenesis of this CNS autoimmune disorder.

Abstract
Background
Propofol is a common sedative-hypnotic drug used for general anesthesia. Recent studies have drawn attention to the antitumor effects of propofol, but the potential mechanism by which propofol suppresses colon cancer stemness and epithelial-mesenchymal transition (EMT) has not been fully elucidated.

Methods
For the in vitro experiments, we used propofol to treat LOVO and SW480 cells and Cell Counting Kit-8 (CCK-8) to detect proliferation. Self-renewal capacity, cell invasion and migration, flow cytometry analysis, qPCR and Western blotting were performed to detect the suppression of propofol to colon cancer cells and the underlying mechanism. Tumorigenicity and immunohistochemistry experiments were performed to confirm the role of propofol in vivo.

Result
We observed that propofol could suppressed stem cell-like characteristics and EMT-related behaviors, including self-renewal capacity, cell invasion and migration in colon cancer cells, and even suppressed tumorigenicity in vivo. Furthermore, investigations of the underlying mechanism revealed that propofol treatment downregulated SIRT1. SIRT1 overexpression or knockdown affected the stemness and EMT of colon cancer cells. Additionally, propofol reversed stemness and EMT in cells with overexpressing SIRT1 and subsequently inhibited the Wnt/β-catenin and PI3K/AKT/mTOR signaling pathways. Wnt/β-catenin pathway inhibitor and PI3K/AKT/mTOR pathway inhibitor blocked the propofol-induced reduction of sphere-formation and cell invasion-migration.

Conclusion
Propofol inhibits LOVO and SW480 cell stemness and EMT by regulating SIRT1 and the Wnt/β-catenin and PI3K/AKT/mTOR signaling pathways. Our findings indicate that propofol inhibits SIRT1 in cancer and is advantageous in colon cancer surgical treatment of patients with high SIRT1 expression.
Under the Veil of Uncertainty: Assessing the Greek Economy’s Resilience and Vulnerability in the Face of Different Uncertainty Types
Authors: Kafka Kyriaki I. 
Published: July 2023

AbstractThis study investigates the impact of uncertainty on sectoral gross value-added (GVA) in the Greek economy, using quarterly data from 1998 to 2022. Analyzing nine types of uncertainty using established indexes, including economic uncertainty and economic, fiscal, monetary, currency, banking, pension, tax, and debt policy uncertainty, the study aims to identify vulnerable and resilient sectors and provide policy recommendations for transforming the Greek economy. The findings contribute to understanding how uncertainty affects different sectors and offer insights into the relationship between uncertainty and sectoral GVA. The study highlights that each sector experiences distinct effects depending on the uncertainty type, with varying impact durations. The “real estate” sector is particularly susceptible to negative impacts, while the “professional, scientific, and technical activities sector, administrative and supportive activities,” the “construction,” and the “wholesale/retail trade” sectors demonstrate high sensitivity to uncertainty shocks. The currency policy and debt policy uncertainty indexes have the most adverse effects on sectoral GVA. This research provides valuable insights for policymakers and decision-makers in pursuing economic stability and growth.
Study of accelerated erosion of elbow-shaped connections with corrosion defects

Published: July 2023

AbstractIn the later stages of gas field development, corrosion and erosion wear often occur in elbow-shaped connections used for gas transportation. Combined with laboratory corrosion experiments, the paper is based on CFD to study the distribution characteristics of pressure and velocity in the flow field for the elbow with pre-set corrosion defects. Simultaneously, the specific procedure is designed to track the formation of Dean vortices, thereby revealing the impact patterns of different corrosion defect features on the erosion outcomes of the elbow. Accordingly, the effect of different arrangement, number and form of corrosion defects on erosion wear was systematically analyzed. The results show that: (1) A comparative analysis of the three different defect distribution forms indicates that erosion occurs mainly at the bend near the outlet Section (45° ~ 60°). Double corrosion defects in the radial distribution will significantly accelerate the rate of pipe erosion, changing the location of maximum erosion rate. (2) By controlling the number of corrosion defects to represent the size of the corroded area, the study reveals as the number of defects increases, the rate and area of erosion in surface of the target material increases significantly. Thus, the area of the corrosion will explicitly change the effect of erosion. (3) As the depth of the defects (corrosion rate) increase, the erosion rate around the radial and axial defects increases exponentially compared to the absence of corrosion, reaching a maximum of 7.8 × 10−6 kg/(m2·s). Corrosion and erosion are two complementary forms of damage to pipe in the production process. The presence of corrosion defects leads to faster erosion rates and changes in the overflow area, reducing service life. Hence, only a reasonable control of both types of wear can ensure the longevity of gas production and transportation.

AbstractZinc oxide nanoparticles, especially those with a high aspect ratio (i. e., nanorods and nanowires), are of great interest for many applications as they are piezoelectric, photocatalytic and antimicrobial. In the present study, a plasma flight-thru synthesis method was developed that allows controlling the particle size and shape of the zinc oxide nanoparticles. In a direct current thermal plasma reactor operated at atmospheric pressure, zinc powder injected into the plasma jet was molten, vaporized and oxidized, which allowed growing zinc oxide nanoparticles. The particle spectrum ranged from small nanospheres to nanorods, nanowires and multipodic nanoparticles such as tetrapods. The influence of the oxygen rate and the plasma power (correlated to the discharge current) on the particle morphology was studied, and the feasibility of the nanowire-like particles as piezoelectric sensor material was investigated. Piezoelectric test sensors, equipped with the plasma-synthesized zinc oxide nanowires, successfully responded to mechanical stimulation after poling.

Abstract
Background
Fluid loss during prolonged exercise in hot conditions poses thermoregulatory and cardiovascular challenges for athletes that can lead to impaired performance. Pre-exercise hyperhydration using nutritional aids is a strategy that may prevent or delay the adverse effects of dehydration and attenuate the impact of heat stress on exercise performance.

Objectives
The aim of this systematic review was to examine the current literature to determine the effect of pre-exercise hyperhydration on performance, key physiological responses and gastrointestinal symptoms.

Methods
English language, full-text articles that compared the intervention with a baseline or placebo condition were included. An electronic search of Medline Complete, SPORTDiscus and Embase were used to identify articles with the final search conducted on 11 October 2022. Studies were assessed using the American Dietetic Association Quality Criteria Checklist.

Results
Thirty-eight studies involving 403 participants (n = 361 males) were included in this review (n = 22 assessed exercise performance or capacity). Two studies reported an improvement in time-trial performance (range 5.7–11.4%), three studies reported an improvement in total work completed (kJ) (range 4–5%) and five studies reported an increase in exercise capacity (range 14.3–26.2%). During constant work rate exercise, nine studies observed a reduced mean heart rate (range 3–11 beats min−1), and eight studies reported a reduced mean core temperature (range 0.1–0.8 °C). Ten studies reported an increase in plasma volume (range 3.5–12.6%) compared with a control. Gastrointestinal symptoms were reported in 26 studies, with differences in severity potentially associated with factors within the ingestion protocol of each study (e.g. treatment, dose, ingestion rate).

Conclusions
Pre-exercise hyperhydration may improve exercise capacity during constant work rate exercise due to a reduced heart rate and core temperature, stemming from an acute increase in plasma volume. The combination of different osmotic aids (e.g. glycerol and sodium) may enhance fluid retention and this area should continue to be explored. Future research should utilise valid and reliable methods of assessing gastrointestinal symptoms. Furthermore, studies should investigate the effect of hyperhydration on different exercise modalities whilst implementing a strong level of blinding. Finally, females are vastly underrepresented, and this remains a key area of interest in this area.

AbstractSecurity of Internet-of-Medical-Things (IoMT) networks has evolved as a vital issue in recent years. The IoMT networks are designed to link patients with caregivers. All reports, data, and medical signals are transferred over these networks. Hence, these networks require robust and secure access strategies for patients to send their vital data or reports. Hence, hacking of these networks may lead to harmful effects on patients. One of the vulnerable points to hacking in these networks is the access point. Access to these networks could be performed with biometrics. The popular biometric traits for this purpose are biomedical signals such as Electrocardiogram (ECG) signals, as they are continuously monitored and measured for patients. A common thread between all biometric authentication systems is the possibility of losing the biometric traits forever if hacking attempts manage to concur the biometric template storage. A new trend in the field of biometric authentication is to avoid the utilization of original biometrics in access control processes. A possible alternative is to use cancelable biometrics instead. Cancelable biometrics can be generated through encryption schemes or non-invertible transforms. This paper adopts both strategies in a unified framework for cancelable ECG signal recognition that can be used in the access step of IoMT networks. The proposed framework begins with applying a non-invertible transformation on the ECG signals through fuzzy logic to change the dynamic range of the signals. As this process is non-invertible in nature, it prevents the recovery of the original ECG signals from the processed versions, which is the main target of cancelable biometric systems. After that, lightweight encryption through XOR operation with user-specific patterns is implemented. Here, the high complexity of full encryption schemes that need a large processing burden is eliminated. The addition of the encryption stage enhances the security of cancelable biometric traits, allowing a hybrid nature of the proposed cancelable biometric framework through the merging of non-invertible transforms and encryption algorithms. Moreover, an FPGA hardware implementation is introduced for real implementation of the proposed ECG-based cancelable biometric recognition framework. This hardware can accompany the user to allow access of the IoMT network when requested. Experimental results show a promising performance of the proposed framework with a large Area under the Receiver Operating Characteristic curve (AROC) of 99.5% and an Equal Error Rate (EER) of 0.058%.
Uncertainty guided ensemble self-training for semi-supervised global field reconstruction
Authors: Zhang Yunyang , Gong Zhiqiang , Zhao Xiaoyu , Yao Wen 
Published: July 2023

AbstractRecovering the global accurate complex physics field from limited sensors is critical to the measurement and control of the engineering system. General reconstruction methods for recovering the field, especially the deep learning with more parameters and better representational ability, usually require large amounts of labeled data which is unaffordable in practice. To solve the problem, this paper proposes uncertainty guided ensemble self-training (UGE-ST), using plentiful unlabeled data to improve reconstruction performance and reduce the required labeled data. A novel self-training framework with the ensemble teacher and pre-training student designed to improve the accuracy of the pseudo-label and remedy the impact of noise is first proposed. On the other hand, uncertainty guided learning is proposed to encourage the model to focus on the highly confident regions of pseudo-labels and mitigate the effects of wrong pseudo-labeling in self-training, improving the performance of the reconstruction model. Experiments including the airfoil velocity and pressure field reconstruction and the electronic components’ temperature field reconstruction indicate that our UGE-ST can save up to 90% of the data with the same accuracy as supervised learning.

Published: July 2023

AbstractSeveral deficiencies exist in the present evaluation of land reclamation quality in mining areas. These include the absence of an established set of evaluation index systems and standard acceptance criteria, as well as the use of traditional sampling techniques, which are costly and in efficiency, and time-consuming. Compared with the traditional sampling survey methods, remote sensing has the advantages of a wide detection range, diverse information collection, multiple data-acquiring strategies, high speed, and short cycle. In this study, we used the Xinzhuang coal mining field in Yongcheng, Henan Province as an example to extract information and invert surface parameters using remote sensing techniques, based on national and local reclamation regulations and standards. Subsequently, using remote sensing, we constructed an index system for evaluating land reclamation quality in three aspects: reclaiming project quality, soil quality, and ecological benefits. Through the grading standards of evaluation indicators and quantitative remote sensing models, we determined the extracted information on the area of indicators, roads, ditches, soil moisture, organic matter, and ecological benefits after reclamation. Based on this, we established a quality evaluation model for mining land reclamation using an improved index and method. The evaluation units were divided, and the weight of the evaluation index was determined using the analytic hierarchy process and data envelopment analysis (AHP–DEA) method. The land reclamation quality in the study area was comprehensively evaluated, field accuracy was verified, and the results were analyzed. The results show that, except for the removal of roads, houses, and fishponds in the study area, all 13 evaluation units achieved a score of 60 points or higher. The quality of reclamation met the standards, and the evaluation results were consistent with the conclusions of the field investigation and project acceptance report, demonstrating the reliability and feasibility of the method developed in this study. The research results will provide technical support for the scientific evaluation of land reclamation quality.
