Abstract

Purpose
Prophylactic insertion of an external ventricular drainage (EVD) prior to the resection of posterior fossa metastases (PFMs) is a common approach to address postoperative transient and permanent hydrocephalus. However, predicting surgery-related hydrocephalus in the preoperative phase continues to be a challenge. This study aims to analyze the incidence, preoperatively collectable risk factors and necessity of perioperative external ventricular drainage placement after posterior fossa metastasis surgery.

Methods
All patients undergoing surgery for PFMs at the authors’ neuro-oncological center between 2015 and 2021 were identified and assessed for postoperative hydrocephalus occurrence. Tumour volume, edema volume, and 4th ventricle volume were assessed on preoperative magnetic resonance imaging scans using the IntelliSpace Portal 5.0. A multivariable logistic regression analysis was performed to identify possible predictors for postoperative hydrocephalus occurrence.

Results
Postoperative hydrocephalus occurred in 14 of the 130 identified PFM patients (11%). Multivariable analysis and receiver operating characteristic (ROC) analysis revealed a 4th -ventricle-to-tumor-volume ratio ≤ 0.02 (OR 33.1, 95% CI 3.8-284.3, p = 0.001), an edema-to- tumor-volume ratio ≤ 0.85 (OR 10.6, 95% CI 2.4–47.4, p = 0.002), an imaging-morphological contact to the 4th ventricle (OR 5, 95% CI 1.4–18, p = 0.013), and multiple intracranial metastases (OR 2.4, 95% CI 1-5.9, p = 0.045) as independent predictors for surgery-related postoperative hydrocephalus occurrence.

Conclusion
The present study identifies preoperatively detectable risk factors for the occurrence of postoperative hydrocephalus following surgery for PFMs. These findings may provide guidance in clinical decision-making regarding prophylactic EVD placement.

Published: November 2024

Abstract
The transformation of wüstite (FeO) in the oxide layer formed during high temperature oxidation (600 °C and 700 °C) on hot-worked tool steel was investigated. Wüstite plays an important role in the oxide layer of these steels used for hot working. However, understanding its transformation behavior during cooling is crucial for controlling the final oxide layer structure. Slow cooling rates have a significant influence on the final wüstite content, resulting in inaccurate representations of the composition of the oxide layer at temperatures above 570 °C. The aim of this study was to determine the influence of cooling rate on the wüstite content in the oxide layer after high temperature oxidation. It was found that for hot-worked steel samples oxidized at 700 °C or higher, a cooling rate of more than 1000 °C min−1 is required to suppress the eutectoid transformation and maintain the realistic wüstite content. At lower temperatures (570 °C–600 °C), a cooling rate of more than 100 °C min−1 is required to achieve the wüstite content observed at oxidation temperatures in the oxide layer. Overall, the hematite and magnetite contents also vart with the cooling rate, which is associated with changes in the wüstite content.
Microalgae as a source of carotenoids in foods, obstacles and solutions
Authors: Mostafa Heba Sayed , Hashem Marwa Mahmoud 
Published: November 2024

AbstractRecently, microalgae have attracted attention as a natural source of healthier bioactive molecules, especially carotenoids, because human bodies lack the ability to synthesize them, and their intake is necessary for human nutrition. Microalgae can produce various classes of these natural products, distinguished by their health benefits. In food sectors, microalgae are available as whole cells or as a source for extracting a specific carotenoid. This review summarizes recent knowledge of the biosynthesis pathway and the factors affecting carotenoid content, as well as strategies for increasing microalgae synthesis of various carotenoids. New uses of carotenoid-rich microalgae in food are highlighted, along with the main challenges and suggested solutions for using microalgal-carotenoids in the foodstuff. Carotenoids, particularly β-carotene and astaxanthin, face significant challenges in terms of bioavailability and stability when included in foods. Although many solutions were proposed, more research is required to determine the stability of other carotenoids under various food processing techniques. Furthermore, future studies should focus on improving bioavailability and accessibility after digestion in order to benefit from all added carotenoids. Modern technology and a fast-paced lifestyle necessitate the inclusion and acceptance of microalgal carotenoids, particularly for the most vulnerable populations, children, and pregnant women.
Lev Karsavin’s Dostoevsky
Authors: Dobieszewski Janusz 
Published: November 2024

AbstractThe thought of Lev Karsavin—like all representatives of the Russian religious and philosophical renaissance—is deeply rooted in the work and ideas of Fyodor Dostoyevsky. However, instead of focusing on the broad relationship between the two thinkers, we focus here on a specific aspect of their connection: two significant articles by Karsavin on Dostoevsky. These are: Dostoevsky and Catholicism (1922) and—or rather primarily—Fyodor Pavlovich Karamazov as an ideologist of love (1921). After a short presentation of the first text, I will try to show the debatable, controversial, but also inspiring and even daring nature of the second text.
The price elasticity of natural gas demand of small consumers in Germany during the energy crisis 2022
Authors: Jamissen David , Vatne Johanne , Holz Franziska , Neumann Anne 
Published: November 2024

AbstractUnderstanding how consumers respond to turbulent market conditions is crucial for planning security of natural gas supply. This paper estimates the price elasticity of demand of small consumers in Germany in the period with both high price fluctuations and a fear of natural gas shortage in the aftermath of the Russian invasion of Ukraine. Using granular data between 2018 and 2023, we estimate an Auto Regressive Distributed Lag (ARDL) time series cointegrating model. We find a price elasticity of demand for natural gas of -0.01 for wholesale prices and -0.04 for retail prices. Additionally, we quantify the effects of weather conditions and public awareness on the energy crisis. The results suggest i) that extreme price changes would be required to trigger short-term demand adjustments, and ii) demonstrate the importance of public attention on the crisis situation.
Ecological Threats and Cultural Systems
Authors: Shapouri Soheil , Rafiee Yasaman 
Published: November 2024

Abstract
Considering the role of human interactions in infectious disease outbreaks and cooperation in mitigating natural disasters consequences, ecological threats to human survival have been among proposed drivers of collectivism. Utilizing established and novel measures of parasite stress and natural disasters, we investigated their association with collectivism in a large sample of countries (N = 188). Linear mixed-effect models indicated that after controlling for national wealth, neither natural disasters nor infectious disease can predict collectivism scores. Null results were consistent across different measures of threats, suggesting that previous findings can be attributed to small, non-representative samples of cultures. When universal patterns are a major concern, drawing conclusions based on small, nonrepresentative subsets of cultures risks promoting unreliable findings. Future cross-cultural research will benefit from data-driven exploratory methods to uncover factors previously unexamined in the theory-driven studies of collectivism.
Pathways to Integration and Language Acquisition: A Comparative Analysis of Refugee Children’s Social Integration and Foreign Language Difficulty in Lebanon and Australia
Authors: Hammoud Mohammad 
Published: November 2024

AbstractThis paper investigates the relationship between refugee children’s social integration and foreign language difficulty. It also examines how different legal settlements and their accompanying education paradigms impact refugee students’ integration and language difficulties in Lebanon and Australia, where short- and long-term legal settlements are provided. The study is based on a longitudinal survey data collected between the academic years 2018 and 2021, with 1565 observations. Our findings reveal that refugees who felt more welcome in the host country were less likely to have high language difficulties. Conversely, refugees who faced high language difficulties were less likely to feel welcome in the host country. Despite the aforementioned, refugees in Lebanon felt less welcomed in their host country, even though they faced lower language difficulties. Therefore, our study reveals that the successful integration of refugee students in the host country requires comprehensive efforts at various levels. This comprehensive approach includes creating inclusive educational environments and equitable policies that promote a sense of belonging while also addressing language comprehension challenges among refugee students.

Abstract
Although the prognosis of breast cancer has significantly improved compared to other types of cancer, there are still some patients who expire due to recurrence or metastasis. Therefore, it is necessary to develop a method to identify patients with poor prognosis at the early stages of cancer. In the process of discovering new prognostic markers from genes of unknown function, we found that the expression of C1orf50 determines the prognosis of breast cancer patients, especially for those with Luminal A breast cancer. This study aims to elucidate the molecular role of C1orf50 in breast cancer progression. Bioinformatic analyses of the breast cancer dataset of TCGA, and in vitro analyses, reveal the molecular pathways influenced by C1orf50 expression. C1orf50 knockdown suppressed the cell cycle of breast cancer cells and weakened their ability to maintain the undifferentiated state and self-renewal capacity. Interestingly, upregulation of C1orf50 increased sensitivity to CDK4/6 inhibition. In addition, C1orf50 was found to be more abundant in breast cancer cells than in normal breast epithelium, suggesting C1orf50’s involvement in breast cancer pathogenesis. Furthermore, the mRNA expression level of C1orf50 was positively correlated with the expression of PD-L1 and its related factors. These results suggest that C1orf50 promotes breast cancer progression through cell cycle upregulation, maintenance of cancer stemness, and immune evasion mechanisms. Our study uncovers the biological functions of C1orf50 in Luminal breast cancer progression, a finding not previously reported in any type of cancer.
Does Domestic Concentration Cancel the Potentially Beneficial Effect of International Competition on Firm Productivity? Evidence from Manufacturing Firms in Cameroon
Authors: Fambeu Ariel Herbert , Yomi Patricia Tchawa 
Published: November 2024

AbstractUsing manufacturing firm-level data from the World Bank Enterprise Surveys (WBES) in 2009 and 2016 and Cameroon’s general enterprise censuses, this paper empirically investigates the joint effect of domestic concentration and international competition on productivity. Instrumental variable estimates suggest that exports improve the productivity of firms operating only in industries where concentration is very low. Moreover, participation in the international market has no effect on the productivity of firms operating in the moderately and highly concentrated sectors. Thus, although concentration has no direct effect on productivity, it nevertheless reduces the positive effect of international competition (through exports). This study not only serves as a reference for future investigations but also carries significant theoretical and empirical implications.
Using Picturebooks as a Pedagogical Tool to Teach Drawing: A Case Study in a Preschool in China
Authors: Qiming Xia , Renganathan Sumathi 
Published: November 2024

AbstractThis study investigates the use of picturebooks as a pedagogical tool to teach drawing skills for preschoolers. Conducted in a public preschool in China, this study is part of a larger project aimed at implementing a learner-centred approach by utilising picturebooks in preschool lessons. Through classroom observations and interviews with teachers, the study explored how drawing lessons were planned, structured, and executed by incorporating picturebooks. It also examined teachers’ beliefs and attitudes in using this approach. While the findings indicated that picturebooks fostered children’s creativity and engagement, the lessons were still predominately teacher centred. Moreover, teachers reported challenges in selecting appropriate picturebooks and balancing the focus between literacy and drawing instruction. The study further revealed how parental expectations added pressure on teachers to deliver visually appealing results, which sometimes limited children’s creative freedom.

Published: November 2024

AbstractThis article and its Online Supplemental Material describe the development of the California School Wellness Index (CSWI), a tool to aid mental health research and practice in schools, specifically for wellness screening and monitoring. The CSWI is a 0–40 composite index derived from responses to the Brief Multidimensional Student Life Satisfaction Scale (BMSLSS) and the Social Emotional Distress Scale (SEDS) and rooted in the Dual-Factor Mental Health model. The development of the CSWI involved psychometric and normative analyses using data from 626,940 California secondary students during the 2021/22 and 2022/23 academic years. Analyses conducted with other independent samples examined concurrent validity with the Social Emotional Health Survey-Secondary (N = 78,769, collected in 2020/21) and stability and predictive validity with the Mental Health Continuum-Short Form (N = 1,828, collected in 2020/21 and 2021/22). Distribution and ranking information and clinical interpretation resources for the BMSLSS, SEDS, and CSWI are described. The discussion and Online Supplemental Material provide insights into strategies for using the CSWI within a Multi-Tiered Support System (MTSS) for various research and clinical applications. These applications include using it as a population-level global mental health index, identifying students needing more support, communicating with educators, guardians, and community members about student well-being, and evaluating the effectiveness of student support services. The Online Supplemental Material includes development, validation, and interpretation information and open-access resources for using the CSWI across MTSS levels.
Novel Hellinger clustering method for efficient ECG optimized classification
Authors: Rfys Rawaa R. , Al-Shammary Dhiah , Mahdi Ahmed M. , Sufi Fahim 
Published: November 2024

Abstract
This paper develops a new clustering technique based on Hellinger distance (HD) that can improve the Particle Swarm Optimization (PSO) search. Selection of features plays an important role in disease detection. Evidently, most machine learning algorithms are unable to accurately identify the optimal features in medical datasets due to the complexity of the data. The main objective of utilizing Hellinger distance is to partition dataset into two groups that are both highly similar and harmonious. Consequently, improve the accuracy of the proposed system by applying particle swarm optimization (PSO) to select more effective features. Technically, the extracted features from compiled MIT-BIH Arrhythmia dataset are applied to Minkowski classifier and several machine learning algorithms: KNN, DT, SVM, RF, and NB. The experiments demonstrated that the suggested model improves performance for classifying ECG signals by increasing accuracy, which reflects the importance of the modification made.
An empirical study of the well-being of older individuals in China, Japan, and Korea
Authors: İmrohoroğlu Selahattin , Yu Zhixiu 
Published: November 2024

AbstractIn this paper we present new empirical findings on the determinants of well-being of 54–75 year old individuals in China, Japan, and Korea. Using the harmonized Health and Retirement Surveys (HRS) that are designed to be similar to the Rand HRS, namely CHARLS in China, JSTAR in Japan and KLoSA in Korea, we run country- and gender-specific panel regressions using all available waves measures of subjective well-being (SWB) are associated with various economic, social, and demographic characteristics. Consistent with previous findings that highlight the role of education, health, employment status and social interactions in single wave studies, we find that these common factors continue to be important across countries and over time. In addition, we find that older Korean individuals in more recent waves have lower SWB than those in the first wave (2006). Finally, we find that there remain important differences across countries about the role of factors such as housing wealth, relative income and sources of life satisfaction, suggesting further country-specific research into the determinants of well-being.
More love troubles: Emma Gordon on biomedical enhancements and love relationships
Authors: Nyholm Sven 
Published: November 2024

Abstract
In my contribution to this book symposium on Emma Gordon’s book Human Enhancement and Well-Being, I discuss and respond to Gordon’s extensive discussion and criticisms of a skeptical argument regarding the desirability of love enhancements that I presented in a 2015 paper. I start by first explaining the overall project of Gordon’s book, make a general comment about her overall approach (which I am broadly sympathetic with), and then proceed to a detailed discussion of Gordon’s critical engagement with my 2015 argument. I defend my argument against Gordon’s interesting criticisms and argue that Gordon has not defused my skeptical challenge to the desirability of love enhancements, but I also end by identifying key points of agreement between me and Gordon. Specific topics discussed include the distinction between ways of loving and causes of loving, the value of ways of loving and the value of the causes of loving, and whether or not the ideal of robust love attachments can be seen as compatible attachments causally dependent on love enhancements.

Abstract
In order to improve the performance of

$k - \omega $

SST model in turbomachinery, previous studies have used the machine-learning (ML) technique to obtain turbulence models (for example, the ML-RANS EQ model). However, these models do not lead to satisfactory results in complex flows in turbomachinery. In this study, we use non-equilibrium training dataset to obtain a new turbulence model (i.e., the ML-RANS TR-NE-EQ model). Calculations in various cases of turbine cascade flows show that ML-RANS TR-NE-EQ model performs obviously better than ML-RANS EQ model as well as

Fundamental considerations in the design and performance assessment of propulsive fuselage aircraft concepts
Authors: Moirou N.G.M. , Mutangara N.E. , Sanders D.S. 
Published: November 2024

AbstractPropulsive fuselage aircraft complement the two under-wing turbofans of current aircraft with an embedded propulsion system within the airframe to ingest the energy-rich fuselage boundary layer. The key design features of this embedding are examined and related to an aero-propulsive performance assessment undertaken in the absolute reference frame which is believed to best evaluate these effects with intuitive physics-based interpretations. First, this study completes previous investigations on the potential for energy recovery for different fuselage slenderness ratios to characterise the aerodynamics sensitivity to morphed fuselage-tail design changes and potential performance before integrating fully circumferential propulsors. Its installation design space is then explored with macro design parameters (position, size and operating conditions) where an optimum suggests up to 11% fuel savings during cruise and up to 16% when introducing compact nacelles and re-scaling of the under-wing turbofans. Overall, this work provides valuable insights for designers and aerodynamicists on the potential performance of their concepts to meet the environmental targets of future aircraft.
Balancing Power: The Impact of Legal Review on Harmonising the European Electricity Market
Authors: Hancher Leigh , Rumpf Julius 
Published: November 2024

AbstractEuropean electricity regulation has evolved to include a novel category of binding sectoral rules known as terms, conditions, and methodologies (TCMs). These are created within a regulatory framework outlined in delegated Commission regulations by private electricity firms and approved by technocratic agencies, most notably the EU Agency for the Cooperation of Energy Regulators (ACER). Despite their technical nature, TCMs have significant economic impact. This prompts frequent appeals of ACER’s TCM decisions, questioning ACER’s role and the overall institutional equilibrium of the TCM procedure. ACER’s TCM decisions are subject to dual-level legal review – internal by ACER’s Board of Appeal and external by European Courts. This paper uses two case studies to examine how dual-level legal review impacts the institutional balance of the TCM procedure. We find that the two levels of review engage poorly, so that contrary to expectations, legal review creates uncertainty rather than clarity, allowing for considerable pragmatism. These findings show the importance of considering legal review when studying sectoral governance. Policy implications are also significant, as the identified issues inhibit innovation and problem-solving, the raison d’etre of the TCMs.
