Considering the stakeholders’ increasing demand for more information, the International Auditing and Assurance Standard Board, in its quest to bridge the expectation gap, introduced a new expanded audit report format. However, whether this new audit report format is effective in meeting stakeholders’ needs is a significant question that regulators, standard setters and academics are interested in evaluating. This paper aims to examine the impact of the expanded auditor’s reports on stakeholders. The study adopts a qualitative approach and is based on an assessment of previous research conducted on the new audit report standards and the audit report’s implications for stakeholders. The research findings suggest that the inclusion of enhanced information on auditor’s responsibility, understandability of audit report information and the addition of critical information and post- implementation experience are important aspects influencing the effectiveness of the auditor’s report. This study contributes with some key elements that can be helpful to standard setters, regulators, and academics who intend to develop recommendations to make auditor's reports more robust and effective for end-users.

Published: August 2022

Financial reporting literature indicates a research gap regarding the topic of auditor-client negotiation (ACN). Thus, the current paper seeks to present the concept of ACN from a literature review perspective. Further, the research is organized in two main sections, namely: (1) the qualitative analysis, based on previous studies in the field of ACN and (2) the quantitative analysis, which involves the use of specific indicators, such as: level of citations per year, region/ country, journal type etc. Then, the study evolves into new insights and discussions upon the impact of literature review on auditor-client negotiations. Overall, the authors used an extensive analysis of 37 publications collected from Web of Science, selecting the most relevant literature in the fields of business, finance, management, social sciences, and ethics, during the period 1975- 2022. Results show that the concept of ACN is being debated in top journals, totalizing no less than 602 citations, and recording an H- Index of 16. Further on, 8 top journals were identified with more than one publication in the sphere of auditor-client negotiation (ACN), 10 authors that have written at least two papers related to ACN, and not least 7 articles with top citation levels. All the 37 literature sources bring an extensive contribution to the development of ACN concept and represent the background for building new insights and prospective research. The present study has practical implications, as defining the background of ACN helps practitioners to find efficient solutions to their everyday challenges.

Digital technology impacts the 21st century, and it shapes our lifestyle, the way we think and the way we act. This paper presents aspects of the digital transformation of the workplace and how this process requires the creation and development of new skills and competencies for employees today but especially in the future. In this new context, an essential role is played by education, by educational systems that need to adapt to new requirements, precisely so that educators have the skills needed to be more productive. From this perspective, in the paper, the authors present a teaching and learning method called the TADEO method, which encourages learning the skills needed for Education 4.0. This method is based on a technology support software tool to help teachers build their teaching plan, teaching duration, teaching materials, and assessment method. Hybrid work is an opportunity that brings new challenges: the work environment is changing rapidly, and automation is replacing human tasks in order for organizations to thrive. Recruitment has become complicated with the digital transformation, and new challenges are emerging for employers as they need people with the skills needed to cope with a changing work environment. The study was conducted on a sample of respondents from a multinational service company based in western Romania, where the accounting department employees were interviewed to see what they think about artificial intelligence, the implications of robots, and the future at work. This research is based on four objectives that have been achieved and three hypotheses that have been tested. The study results showed that about half (43.7%) of the employees who answered this questionnaire worked in the office. Only 28.2% consider themselves very satisfied with the job, and 37.9% see themselves working at the same company for 10 years.
Dark times, enlightened people. Doctors of the Polish kings from the Wettin dynasty: August II, August III and Frederick August III
Authors: Początek Michał
Published: August 2022

Artykuł ma charakter przeglądowy, a zarazem posiada niektóre cechy eseju. Przedstawia kilkunastu lekarzy nadwornych polskich władców epoki saskiej: Fryderyka Augusta I (1670-1733), elektora saskiego w latach 1697-1733 (z przerwą od 1706 do 1709 r.) zasiadającego na tronie Rzeczypospolitej jako August II, Fryderyka Augusta II (1696-1763) panującego w Polsce w okresie 1733-1763 jako August III oraz księcia elektora Fryderyka Augusta III (1750-1827), który z woli Napoleona został królem Saksonii, a w latach 1807-1815 sprawującym władzę w Księstwie Warszawskim. Sześćdziesiąt lat panowania Wettynów w XVIII wieku uważane jest za ciemną kartę polskich dziejów i przyczynę utraty suwerenności poprzez rozbiory. Z drugiej strony, w tym czasie rozwijała się kultura, powstawały arcydzieła sztuki baroku. Celem artykułu jest wykazanie wysokiego poziomu biegłości zawodowej i wiedzy medycznej lekarzy królewskich.
Dr Leopold Goeppner’s (1766-1824) pioneering fight against smallpox
Authors: Parowcz Izabella
Published: August 2022

Ospa prawdziwa (łac. variola vera) przez stulecia uważana była za najgroźniejszą i najbardziej śmiercionośną chorobę zakaźną, odpowiedzialną za zgon, ślepotę i zniekształcenia ciała niezliczonych rzesz ludzi. Mimo wysiłków lekarzy próbujących zahamować rozprzestrzenianie się ospy lub przynajmniej znaleźć sposób pozwalający pacjentom możliwie łagodnie przebyć tę chorobę, przełomem okazało się dopiero odkrycie Edwarda Jennera, który w 1796 r. dowiódł, że zaszczepienie ludziom wirusa ospy krowiej uodparnia ich na działanie wirusa ospy prawdziwej. Nowa metoda szybko zyskała uznanie medyków w różnych miejscach kontynentu europejskiego i na całym świecie. Niniejszy artykuł przedstawia postać dr. Leopolda Goeppnera (1766-1824), fizyka powiatowego ze Świebodzina, pioniera wakcynacji zarówno w Prusach, jak i na obecnych terenach Polski, który już w 1801 r. rozpoczął szczepienia swoich pacjentów przeciwko ospie prawdziwej. Jego trud został ukazany w świetle niestrudzonych zmagań lekarzy w całej Europie, którzy – wyposażeni w nowy rodzaj broni – wypowiedzieli wojnę tak bardzo znienawidzonej, śmiercionośnej chorobie. Jednocześnie musieli walczyć z przeciwnikami nowej metody immunizacji i z szerzącymi się wśród ludzi przesądami.

Smart health applications have received significant attention in recent years. Novel applications hold significant promise to overcome many of the inconveniences faced by persons with disabilities throughout daily living. For people with blindness and low vision (BLV), environmental perception is compromised, creating myriad difficulties. Precise localization is still a gap in the field and is critical to safe navigation. Conventional GNSS positioning cannot provide satisfactory performance in urban canyons. 3D mapping-aided (3DMA) GNSS may serve as an urban GNSS solution, since the availability of 3D city models has widely increased. As a result, this study developed a real-time 3DMA GNSS-positioning system based on state-of-the-art 3DMA GNSS algorithms. Shadow matching was integrated with likelihood-based ranging 3DMA GNSS, generating positioning hypothesis candidates. To increase robustness, the 3DMA GNSS solution was then optimized with Doppler measurements using factor graph optimization (FGO) in a loosely-coupled fashion. This study also evaluated positioning performance using an advanced wearable system’s recorded data in New York City. The real-time forward processed FGO can provide a root-mean-square error (RMSE) with about 21 m. The RMSE drops to 16 m when the data is post-processed with FGO in a combined direction. Overall results show that the proposed loosely-coupled 3DMA FGO algorithm can provide a better and more robust positioning performance for the multi-sensor integration approach used by this wearable for persons with BLV.

Currently, studies are being conducted on the possible role of the cytoprotective effect of biologically active substances in conditions of cerebral hypoxia or cardiomyopathies. At the same time, oxidative stress is considered as one of the important mechanisms of cellular cytotoxicity and a target for the action of cytoprotectors. The aim of this study is to search for derivatives of 3-(arylmethyl)-6-methyl-4-phenylpyridin-2(1H)-ones. The probability of cytoprotective action was assessed by two tests by measuring cell viability (with neutral red dye and MTT test). It was found that some derivatives of 3-(arylmethyl)-6-methyl-4-phenylpyridin-2(1H)-ones under the conditions of our experiment have a pronounced cytoprotective activity, providing better cell survival in vitro, including the MTT test and conditions of blood hyperviscosity. To correlate the obtained results in vitro, molecular docking of the synthesized derivatives was also carried out. The standard drug omeprazole (co-crystallized with the enzyme) was used as a standard. It was shown that all synthesized derivatives of 3-(arylmethyl)-6-methyl-4-phenylpyridin-2(1H)-ones had higher affinity for the selected protein than the standard gastro-cytoprotector omeprazole. The studied derivatives of 3-(arylmethyl)-6-methyl-4-phenylpyridin-2(1H)-ones also fully satisfy Lipinski's rule of thumb of five (RO5), which increases their chances for possible use as orally active drugs with a good ability to absorption and moderate lipophilicity. Thus, the results obtained make it possible to evaluate derivatives of 3-(arylmethyl)-6-methyl-4-phenylpyridin-2(1H)-ones as having a relatively high cytoprotective potential.

Published: August 2022

Over the last few years, Earth Observation (EO) data has shifted towards increased use to produce official statistics, particularly in the agriculture sector. National statistics offices worldwide, including in Asia and the Pacific, are expanding their use of EO data to produce agricultural statistics such as crop classification, yield estimation, irrigation mapping, and crop loss estimation. The advances in image classification, such as pixel-based and phenology-based classifications, and machine learning create new opportunities for researchers to analyze EO data applied to agriculture statistics. However, it requires the ground truth (GT) data because classification result mainly depends on the quality of GT. Therefore, in this study, we introduced a random sampling approach to design and collect GT data using EO imagery and ancillary data. As a result of data collection, GT data improve the algorithms and validates classification results. Nevertheless, despite the importance of GT data, they are rarely disseminated as a data product in themselves. Thus, this results in an untapped opportunity to share GT data as a global public good, and improved use of survey and census data as a source of GT data.

Published: August 2022

Citron watermelon (Citrullus lanatus var. citroides) is an extremely drought-tolerant cucurbit crop widely grown in sub-Saharan Africa in arid and semi-arid environments characterized by drought. The species is a C3 xerophyte used for multiple purposes, including intercropping with maize and has a deep taproot system. The deep taproot system plays a key role in the species’ adaptation to dry conditions. Understanding root system development of this crop could be useful in identifying traits for breeding water-use efficient and drought-tolerant varieties. This study compared root system architecture of citron watermelon accessions under water-stress conditions. Nine selected and drought-tolerant citron watermelon accessions were grown under non-stress (NS) and water stress (WS) conditions using the root rhizotron procedure in a glasshouse. The following root system architecture (RSA) traits were measured, namely: root system width (RSW), root system depth (RSD), convex hull area (CHA), total root length (TRL), root branch count (RBC), total root volume (TRV), leaf area (LA), leaf number (LN), first seminal root length (FSRL), seminal root angle (SRA), root dry mass (RDM), shoot dry mass (SDM), root–shoot mass ratio (RSM), root mass ratio (RMR), shoot mass ratio (SMR) and root tissue density (RTD). The data collected on RSA traits were subjected to the analysis of variance (ANOVA), correlation and principal component analyses. ANOVA revealed a significant (p < 0.05) accession × water stress interaction effect for studied RSA traits. Under WS, RDM exhibited significant and positive correlations with RSM (r = 0.65), RMR (r = 0.66), RSD (r = 0.66), TRL (r = 0.60), RBC (r = 0.72), FSRL (r = 0.73) and LN (r = 0.70). Principal component analysis revealed high loading scores for the following RSA traits: RSW (0.89), RSD (0.97), TRL (0.99), TRV (0.90), TRL (0.99), RMR (0.96) and RDM (0.76). In conclusion, the study has shown that the identified RSA traits could be useful in crop improvement programmes for citron watermelon genotypes with enhanced drought adaptation for improved yield performance under drought-prone environments.

Published: August 2022

In the context of regional development in Indonesia, Special Economic Zones (SEZs) are designated to accommodate industrial and economic activities for regional acceleration. To date, Indonesia has 19 Special Economic Zones that have been designated, one of which is the Bitung SEZ. In its designation, the Bitung SEZ focused on the fishery and coconut processing industry, as well as its derivative products. The development of the Bitung SEZ as a government product in the plan is expected to give trickling down effects to the surrounding, but in the practice, it does not escape problems (in the spatial, institutional, and socio-economic aspects). Thus, this paper aims to explain how the establishment and operational dynamics of the Bitung SEZ are based on the physical, policy, and social dimensions as dualism in development. This research used mixed methods, with data sources and materials obtained from the research, news, and planning documents. The findings of this study, the dualism of development occurs in both theoretical and practical settings, instead of creating a new growth center, development can also cause some problems.

The Rise and Fall of Homegrown Concepts in Global IR: The Anatomy of ‘Strategic Depth’ in Turkish IR
Authors: BAKİR Ali , ERSOY Eyüp
Published: August 2022

Asymmetry of knowledge production in global international relations manifests
itself in a variety of forms. Concept cultivation is a foundational form that
conditions the epistemic hierarchies prevalent in scholarly encounters,
exchanges, and productions. The core represents the seemingly natural ecology
of concept cultivation, while the periphery appropriates the cultivated concepts,
relinquishing any claim of authenticity and indigeneity in the process. Nonetheless,
there have been cases of intellectual undertakings in the periphery to conceive,
formulate, and articulate conceptual frames of knowledge production. This paper,
first, discusses the fluctuating fortunes of homegrown concepts in the peripheral
epistemic ecologies. Second, it introduces the concept of ‘strategic depth’ as
articulated by the Turkish scholar Ahmet Davutoğlu and reviews its significance
for the formulation and implementation of recent Turkish foreign policy. Third,
it examines the causes of its recognition and acclaim in the local and global IR
communities subsequent to its inception. The paper contends that there have been
three fundamental sets of causes for the initial ascendancy of the concept. These
are categorized as contemplative causes, implementative causes, and evaluative
causes. Fourth, it traces the sources of its fall from scholarly grace. The paper
further asserts that the three fundamental sets of causes were also operational in
the eventual conceptual insolvency of strategic depth. The paper concludes by
addressing remedial measures to vivify concept cultivation in the periphery and
to conserve the cultivated concepts.

Authors: Desi Ariska  , Ahmad Diponegoro  , Fatwa Tentama
Published: August 2022

Research on self-efficacy is hotly discussed, especially in this time of pandemic. As for knowing the high or low self-efficacy, a valid and reliable measuring instrument is needed. The purpose of this study was to develop a teacher self-efficacy scale using SEM modeling based on Bandura's theory. The aspects of self-efficacy that are used as a reference for making measuring instruments consist of level, strength, and generality. The study was conducted on 100 Vocational High School teachers. The measuring instrument is arranged using the Likert model. The validity and reliability test used the confirmatory factor analysis (CFA) approach with the help of PLS ​​3.29 software. The results showed that the self-efficacy measurement tool was declared valid and reliable because all items from the dimensions were able to reflect the 110 constructs that were formed. This measuring instrument is also declared valid and reliable where there are 12 items that have fallen out of the 30 items submitted.
EL CONTROL FISCAL AL PRESUPUESTO PARTICIPATIVO DE MEDELLÍN. UN ABORDAJE DESDE LOS MODELOS DE ADMINISTRACIÓN PÚBLICA
Authors:   Universidad EAFIT, Franco Vargas María Helena , Ramírez Trujillo Julián
Published: August 2022

This paper explains how fiscal control operated on the participatory budget operated in Medellín, during the 2014-2018 period, under the vision of public administration models. Punctually, this text investigates the criteria followed by the General Comptroller of Medellín to carry out discretionary fiscal control of projects implemented through the Participatory Budget of Medellín. To achieve the above, a qualitative research was carried out; this research involved the use of different strategies. The findings show that fiscal control, activated by the entities of citizen control and the Medellín Council, demonstrate the coordinated work of different actors. But, on the other hand, the discretionary fiscal control exercised by the Comptroller’s Office does not respond to the guidelines of the law, typical of a bureaucratic legalistic model, which makes the selection procedure for such projects arbitrary and diffuse. It is observed that the current institutional design favors this situation.
EUTANASIA: UN CUERPO DICE NO, UNA VOLUNTAD QUE RECLAMA DIGNIDAD
Authors:   Universidad Libre, Mazuera Ayala Paula , Mazuera Ayala Andrea
Published: August 2022

This article proposes to analyze euthanasia from a socio-legal angle, understanding that if there is a legal and medical framework in Colombia that addresses this practice, the evidence reveals that various cultural, institutional, political and social elements permeated the application, creating an authentic legal problem, with severe connotations in the relationship between individual freedoms and the social rule of law. To carry out this analysis, a joint interpretation of legal, theoretical, medical, scientific and journalistic elements was carried out that would contribute to the critical understanding of access to euthanasia and of the bodily reality of the patient as a subject of law.

Authors: Haehnel Robert , Wenren Yonghu , Allen Luke
Published: August 2022

Numerical modeling of snowdrifting is a useful tool for assessing the impact of building design on operations and facility maintenance. Here we outline the theory for the SAGE-PEDD snowdrift model that has application for determining snowdrift accumulation around buildings. This model uses the SAGE computational fluid dynamics code to determine the flow field in the computational domain. A particle entrainment, dispersion, and deposition (PEDD) model is coupled to SAGE to simulate the movement and deposition of the snow within the computational domain. The report also outlines areas of future development that upgrades to the SAGE-PEDD model should address.

Objective: To analyse the relationship between leadership styles, personal values ​​of nursing leaders and the Quality of Work Life of nurses who attend the Graduate Program in Nursing Management (PPGEn). Methods: This is a quantitative, cross-sectional study. Data were collected using the standardized instrument Quality of Working Life Questionnaire (QWLQ-bref), and an exploratory-descriptive analysis was performed. Results: Of the 123 nurses interviewed, 64.22% rated the Quality of Work Life as satisfactory and 31.7% as very satisfactory. Through these data, the relationship between the task leadership style and professional satisfaction in the nurse's quality of life was perceived. Conclusion: The results do not point to a relationship between the managerial style of the nurse leader and the perception of Quality of Work Life. However, it is noteworthy that the Quality of Work Life describes values ​​that go beyond the human.
Examining the role of biomass energy for sustainable environment in African countries
Authors: Raji Jimoh Olajide , Adeel-Farooq Rana Muhammad , Qamri Ghulam Muhammad
Published: August 2022

Purpose-
This paper investigates the influences of biomass energy use, fossil fuel, income, trade openness, and population growth on carbon dioxide (C02) emission in African countries over the 1980–2014 period.
Design/methodology/approach-
The study employs pool mean group (PMG), mean group (MG), and dynamic fixed effect (DFE) estimators that resolve the issue of heterogeneity bias. In addition, it employs weighted fully modified ordinary least squares, and weighted dynamic ordinary least squares to validate the robustness of PMG, MG, and DFE estimates.
Findings-
The results from each of these estimators complement one another and both suggest that the relation of fossil fuel use and population growth with CO2 emission is positively significant. Conversely, we find that trade openness and biomass energy use exert significant negative impact on carbon emission. Additionally, the dampening effect of biomass energy utilization on CO2 emission helps to validate Environmental Kuznets Curve (EKC) hypothesis for those countries.
Originality/value-
The role of biomass in determining environmental quality has been investigated by studies for a few developed economies and developing countries without reaching consensus in terms of their findings. As indicated by the literature, such study is wanting in African countries, and this motivates the present study. More so, with focus on the role of biomass in CO2 emission, this study first considers sixteen countries from all the regions on the African continent. The findings of this study will assist policy makers in making useful environmental and sustainable energy policy that can be embraced as regional policy.
Vibrational resonance in 100-kyr glacial cycles
Authors: Mitsui Takahito , Willeit Matteo , Boers Niklas
Published: August 2022

During the last one million years, ice ages occurred with a dominant periodicity of 100 kyr (1 kyr = 1,000 years), while the solar radiation variability resulting from astronomical forcing is concentrated at higher frequencies and shows negligibly small power around this time scale. Although many promising frameworks have been introduced to solve this 100-kyr problem, a comprehensive theory of glacial cycles remains elusive. Here we show, using an Earth System Model of intermediate complexity, that the 100-kyr glacial cycles can be explained via a phenomenon called vibrational resonance. We demonstrate that the Earth system's response to the climatic precession, whose amplitude is modulated by the eccentricity with 100-kyr and 400-kyr periodicities, is amplified at the 100-kyr time scale and suppressed at the 400-kyr time scale with the help of the 41-kyr obliquity forcing. Our results also suggest that the present interglacial would not have appeared without the vibrational resonance discovered here.

BackgroundData collection is a substantial part of trial workload for participants and staff alike. How these hours of work are spent is important because stakeholders are more interested in some outcomes than others. The ORINOCO study compared the time spent collecting primary outcome data to the time spent collecting secondary outcome data in a cohort of trials.MethodsWe searched PubMed for phase III trials indexed between 2015 and 2019. From these, we randomly selected 120 trials evaluating a therapeutic intervention plus an additional random selection of 20 trials evaluating a public health intervention. We also added eligible trials from a cohort of 189 trials in rheumatology that had used the same core outcome set.We then obtained the time taken to collect primary and secondary outcomes in each trial. We used a hierarchy of methods that included data in trial reports, contacting the trial team, and approaching individuals with experience of using the identified outcome measures. We calculated the primary:secondary data collection time ratio and notional data collection cost for each included trial.ResultsWe included 161 trials (120 Phase III; 21 Core outcome set; 20 Public health), which together collected 230 primary and 688 secondary outcomes. Full primary and secondary timing data were obtained for 134 trials. The median time spent on primaries was 56 hours (range 0.0 – 10,747) and the median time spent on secondaries was 191 hours (range 0.0 – 1,356,833). The median primary:secondary data collection time ratio was 1:3.0 (i.e. for every minute spent on primary outcomes, 3.0 were spent on secondaries. The ratio varied by trial type: Phase III trials were 1: 3.1, Core outcome set 1:3.4 and Public health trials 1:2.2. The median notional overall data collection cost was £8,016 (range £53 – £31,899,141).ConclusionsDepending on trial type, between two and three times as much time is spent collecting secondary outcome data than collecting primary outcome data. Trial teams should explicitly consider how long it will take to collect the data for an outcome and decide whether that time is worth it given importance of the outcome to the trial.

Objective: To investigate the effect and mechanism of breast cancer cell-derived extracellular vesicles (EVs) on the biological characteristics of Human umbilical vein endothelial cells (HUVECs). Methods: MDA-MB-231 and MCF-7 breast cancer cell-derived EVs were extracted to treat HUVECs with different concentrations (0, 10, 20 and 40 μg/mL) respectively for different times. The proliferation was detected by MTT assay and plate clone formation assay. Transwell assay was used to detect the migration and invasion，scratch wound assay was used to detect the migration and Western blotting was to detect related protein expression of JAK2/STAT3 signaling pathway. Results: Compared with 0μg/mL MDA-MB-231 and MCF-7 breast cancer cell-derived EVs, the specific concentration (10, 20 and 40 μg/mL ) of breast cancer cell-derived EVs improved the proliferation, plate cloning and migration of HUVECs significantly (P<0.05); there was no significant difference in total JAK2 and STAT3 protein expression (P<0.05), while the expression of p-JAK2 and p-STAT3 protein increased significantly (P<0.05).Conclusion: Breast cancer cell-derived EVs might promote the proliferation and migration of HUVECs by regulating the phosphorylation of JAK2/STAT3 signaling pathway.

In this work we used a new organic bio flocculant (BF), which we extracted from natural seeds of Lepidium Sativum (LS). This extract is known for it’s performance in various fields such as cosmetology, pharmacology and food products. Moreover, it does not present any danger to human health. The main purpose of our study is the exploitation of a new natural supports, as bio polymers in the treatment of water loaded with marl limestone suspended solids (SS) and trace elements, including Copper and zinc. We studied the effectiveness of this extract in comparison with other products usually used in the treatment and depollution of water; the preliminary tests were carried out on pseudo samples prepared at the laboratory level. The comparative study with a synthetic flocculant (Anionic polyacrylamide: APA), usually used in water treatment, provided a good competitiveness with an important flocculation power. The combination of the two steps of neutralization and coagulation by aluminum sulfate (AS), followed by a flocculation step by the new flocculant (LS), then a natural decantation, gave significant results, in the abatement of Cu2+, Zn2+ and (SS). For the solution rich in marl limestone, the turbidity passes from an average of 600 NTU to values close to 1 NTU. The sludge thus produced after treatment is submitted to an analysis by (SEM) and (XRD) and the retained chemical elements are detected. The study generally enters as a sustainable development strategy capable of improving long-term global water security and protecting the environment from synthetic products used excessively in water treatment.

Background: Large datasets are required to ensure reliable non-invasive glioma assessment with radiomics-based machine learning methods. This can often only be achieved by pooling images from different centers. Moreover, trained models should perform with high accuracy when applied to data from different centers. In this study, the impact of reconstruction settings and segmentation methods on radiomic features derived from amino acid and TSPO PET images of glioma patients was examined. Additionally, the ability to model and thus reduce feature differences was investigated. [18F]FET and [18F]GE-180 PET data were acquired from 19 glioma patients. For each acquisition, 10 reconstruction settings and 9 segmentation methods were included to emulate multicentric data. Statistical robustness measures were calculated before and after ComBat harmonization. Differences between features due to setting variations were assessed using Friedman test, coefficient of variation (CV) and inter-rater reliability measures, including intraclass and Spearman’s rank correlation coefficients and Fleiss’ Kappa.Results: According to Friedman analyses, most features (> 60%) showed significant differences. Yet, CV and inter-rater reliability measures indicated higher robustness. ComBat resulted in almost complete harmonization (> 87%) according to Friedman test and little to no improvement according to CV and inter-rater reliability measures. [18F]GE-180 features displayed higher sensitivity to reconstruction settings than [18F]FET features.Conclusions: According to Friedman test, feature distributions could be successfully aligned using ComBat. However, depending on settings, changes in patient ranks were observed for some features and could not be eliminated by harmonization. Thus, for clinical utilization it is recommended to exclude affected features.

Protein disulfide isomerase (PDI) is an endoplasmic reticulum (ER) enzyme that mediates the formation of disulfide bonds, and is also a therapeutic target for cancer treatment. Our previous studies found that PDI mediates apoptotic signaling by inducing mitochondrial dysfunction. Considering that mitochondrial dysfunction is a major contributor to autophagy, how PDI regulates autophagy remains unclear. Here, we provide evidence that high expression of PDI in colorectal cancer (CRC) tumors significantly increases the risk of metastasis and poor prognosis of cancer patients. PDI inhibits radio/chemo-induced cell death by regulating autophagy signaling. Mechanistically, the combination of PDI and GRP78 was enhanced after endoplasmic reticulum stress (ERS), which inhibits the degradation of AKT by GRP78, and eventually activates the mTOR pathway to inhibit autophagy initiation. In parallel, PDI can directly interact with the mitophagy receptor PHB2 in mitochondrial, then competitively blocks the binding of LC3Ⅱ and PHB2 and inhibits the mitophagy signaling. Collectively, our results identify PDI can reduce radio/chemo-sensitivity by regulating autophagy, which provides credence to screening for PDI to guide therapeutic decisions.
Numerical evidence for a small-scale dynamo approaching solar magnetic Prandtl numbers

Magnetic fields on small scales are ubiquitous in the universe. Though they can often be observed in detail, their generation mechanisms are not fully understood. One possibility is the so-called small-scale dynamo (SSD). Prevailing numerical evidence, however, appears to indicate that an SSD is unlikely to exist at very low magnetic Prandtl numbers (PrM) such as are present in the Sun and other cool stars. We have performed high-resolution simulations of isothermal forced turbulence employing the lowest PrM values ever achieved. Contrary to earlier findings, the SSD turns out to be not only possible for PrM down to 0.0031, but to become even increasingly easier to excite for PrM below ≈0.05. We relate this behaviour to the known hydrodynamic phenomenon, referred to as the bottleneck effect. Extrapolating our results to solar values of PrM indicates that an SSD would be possible under such conditions.
