Authors: Veasaw Kassidy , Poltiyelova Elona , Lin Zilan , Kumar Anila , Pais Shireen 
Published: August 2024

ABSTRACT
Ectopic varices are portosystemic collaterals that form outside the esophagogastric region. If left untreated, they can carry a high mortality rate. Although ectopic variceal bleeding occurs rarely, it continues to pose both diagnostic and therapeutic challenges and remains an under-recognized source of gastrointestinal (GI) hemorrhage. We present a case of GI bleeding from varices formed at the choledochojejunosomy site in a post-Whipple patient. This case describes the rare finding of ectopic varices after pancreaticoduodenectomy, emphasizes the challenges in diagnosis and treatment, and highlights the need for a multidisciplinary approach managing GI bleeding in this patient population.

Effective Cynicism
Authors: Plueckhahn Rebekah 
Published: August 2024

In this article, I show how “effective cynicism” allows residents to decipher unequal power relations in Ulaanbaatar, Mongolia. Ethnographic analysis of the myriad ways residents hold onto dilapidated housing in a failed redevelopment scheme reveals how residents’ cynical reflections assist in their efforts to decipher and mobilize state authority. Residents undertake this while simultaneously negotiating the insidious decay of waste accumulated as a by-product of failed redevelopment processes. Throughout, I focus on the presence of waste and cynicism as phenomena that both foreclose and open possibilities. I argue that residents’ repurposing of cynicism as a diagnostic tool, rather than producing detachment, presents a reframing of Peter Sloterdijk’s (1987) discussions of cynical realism, where such realism holds generative potential. Considering the lived experience of urban decay through the three-pronged analytical framework of cynicism, power, and waste reveals subtle residential reconfigurations emerging within the materialities of for-profit redevelopment.

Media and policy legitimacy: A study of news coverage of the Flemish Human Rights Institute
Authors: Steeman Lise-Lore , d’Haenens Leen , Fobé Ellen 
Published: August 2024

Abstract
European countries are required to establish equality bodies to combat discrimination. For the success of such bodies, informing citizens about their existence and functioning is essential. Therefore, this study conducts a thematic content analysis of news coverage (N = 129 Flemish news articles) pertaining to the recently established Flemish Human Rights Institute (FHRI) in Belgium. The analysis focuses on the subjects addressed in the news articles, the individuals or groups involved, and the interpretation of the three components of the responsiveness triangle (policy system, social perspectives, and policy environment), which collectively determine the perception of a legitimate policy. The study’s findings reveal that the articles extensively feature varying viewpoints from politicians and civil society organizations regarding the FHRI’s policy system, including its competences, institutional formation, and operation, as well as its role in protecting citizens’ rights. However, the news articles refrain from offering a conclusive assessment of the institution’s legitimacy.
Optimization strategies for graphene-based protection coatings: a review
Authors: Han Qing , Wang Rongnan , Xue Yunzhou , Camilli Luca , Yu Gui , Luo Birong 
Published: August 2024

Abstract
Graphene has become an emerging and promising option in the field of protection coating for anti-corrosion due to its specific properties in chemical inertia and physical impermeability. It can be applied to metal protection coating in forms of either atomically thin films or composite materials, known, respectively, as pure chemical vapour deposition (CVD) graphene coatings and graphene composite coatings (GCCs). Nonetheless, various structure defects, synthesis imperfections and graphene’s positive potential to metals would make graphene-based protective coatings tend to exhibit corrosion promotion by arousing micro-galvanic corrosion, largely undermining its anti-corrosion efficiency. Based on this, many optimization strategies and methods have been conceived and applied to the graphene-based protection coatings in these two aspects for improving its anti-corrosion efficiency. For example, a good dispersion and orderly arrangement of graphene derivatives in the GCCs can largely optimize its anti-corrosion performance. Here, this paper separately reviews detailed optimization strategies, corresponding mechanisms and key factors for the use of representative graphene-based materials in these two aspects, with the aim of providing comprehensive knowledge and a roadmap of developing cheap, powerful and effective barrier technologies. Finally, perspectives on opportunities and challenges in improving the barrier coating efficiency of graphene-based materials are discussed.
Root cycles in Coxeter groups

Published: August 2024

Abstract
For an element 𝑤 of a Coxeter group 𝑊, there are two important attributes, namely its length, and its expression as a product of disjoint cycles in its action on Φ, the root system of 𝑊.
This paper investigates the interaction between these two features of 𝑤, introducing the notion of the crossing number of 𝑤,

Writing

Published: August 2024

Abstract
This article explores the dynamics of nanofluids consisting of copper (TiO2) nanoparticles suspended in water, as they interact with sensor surfaces between two parallel squeezing plates with porous characteristics. This research specifically targets applications involving enhanced heat transfer and magnetohydrodynamic (MHD) control in nanofluid systems. The primary aim is to analyze the effects of nanoparticle aggregation and non-aggregation on sensor surfaces, considering MHD formations and heat transfer in the energy and momentum equations. The research adopts a steady-state fluid condition and utilizes similarity transformations to convert partial differential equations into more manageable ordinary differential equations. The methodology involves shooting methods for solving these nonlinear ordinary differential equations and employs graphical analyses to study the impacts of various parameters such as permeability, magnetic influence, squeeze flow, and radiation on the temperature and velocity profiles of the nanofluid. The results reveal significant dependencies of temperature and velocity profiles on the studied parameters, illustrating varied behaviors in scenarios of both aggregation and non-aggregation of nanoparticles. The findings emphasize how each parameter distinctively influences the heat and flow characteristics of the nanofluid, offering insights into optimizing conditions for better performance and control in practical applications. Future research could focus on extending the model to include transient fluid states and exploring the effects of other nanoparticle materials and shapes. There is also potential to investigate the interactions under different environmental conditions and to incorporate more complex boundary conditions to simulate real-world applications more accurately. Further experimental validation of the theoretical predictions would be beneficial to enhance the reliability and applicability of the findings.

Published: August 2024

Abstract
Using rice husk ash (RHA) as a cement substitute in concrete production has potential benefits, including cement consumption and mitigating environmental effects. The feasibility of RHA on concrete strength was investigated in this research by predicting the split tensile strength (SPT) and flexural strength (FS) of RHA concrete (RHAC). The study used machine learning (ML) methods such as ensemble stacking and gene expression programming (GEP). The stacking model was improved using base learner configurations ML models, such as, random forest (RF), support vector regression, and gradient boosting regression. The proposed models were validated by statistical tests and external validation criteria. Moreover, the effect of input parameters was investigated using Shapley adaptive exPlanations (SHAP) for RF and parametric analysis for GEP-based models. The analysis revealed that the stacking ensemble integrates base learner predictions and demonstrated superior performance, with R values greater than 0.98 and 0.96. Mean absolute error and root mean square error values for both SPT and FS were 0.23, 0.3, 0.5, and 0.7 MPA, respectively. The SHAP analysis demonstrated water, cement, superplasticizer, and age as influential parameters for the RHAC strength. Furthermore, the SPT and FS of RHAC can be predicted with an acceptable error using the GEP expressions in the standard design procedure.

Wave Downscaling Approach with TCN model, Case Study in Bengkulu, Indonesia
Authors: Navialdy Dio , Adytia Didit 
Published: August 2024

When conducting marine operations that rely on wave conditions, such as maritime trade, the fishing industry, and ocean energy, accurate wave downscaling is important, especially in coastal locations with complicated geometries. Traditional approaches for wave downscaling are usually obtained by performing nested simulations on a high-resolution local grid from global grid information. However, this approach requires high computation resources. In this paper, to downscale global wave height data into a high-resolution local wave height with less computation resources, we propose a machine learning-based approach to downscaling using the Temporal Convolutional Network (TCN) model. To train the model, we obtain the wave dataset using the SWAN model in a local domain. The global datasets are taken from the ECMWF Reanalysis (ERA-5) and used to train the model. We choose the coastal area of Bengkulu, Indonesia, as a case study. The results of TCN are also compared with other models such as LSTM and Transformers. It showed that TCN demonstrated superior performance with a CC of 0.984, RMSE of 0.077, and MAPE of 4.638, outperforming the other models in terms of accuracy and computational efficiency. It proves that our TCN model can be alternative model to downscale in Bengkulu’s coastal area.
Probabilistic Programming for Transportable Source Characterization and Uncertainty Quantification of the North Korean Nuclear Tests 2006–2017
Authors: Alfaro-Diaz Richard , Kintner Jonas , Scott Phillips W. , Delbridge Brent , Carmichael Josh 
Published: August 2024

Abstract
We introduce a transportable technique to determine the yield and depth of burial (DOB) from seismic source spectra of underground nuclear explosions. We demonstrate this technique on the six declared North Korean nuclear tests. This approach derives source spectra in absolute units from regional phase (Pg) amplitudes by correcting the observations for geometric spreading, attenuation, and site amplification. We couple the source spectra and explosion source models with a probabilistic programming framework that integrates deep learning techniques and Bayesian modeling. This approach permits the exchange of information across various data categories to quantify both the data and model uncertainty. This technique stands out as an innovative use of broad-area propagation models, making it transportable across various geologic settings. This method proves to be effective in scenarios with diverse and/or limited observational data, even when the source depth is unknown. We present new independent estimates of absolute yield and DOB that are consistent with the prior assessments, underscoring the potential of this method in enhancing transportable nuclear explosion monitoring capabilities.

Published: August 2024

Nowadays, hybrid contracts are recognized as an adaptive form of contract in the implementation of Islamic business. However, the involvement of hybrid contracts in al-Rahn has risen numerous legal controversies in Islamic Sharia. Malaysia and Indonesia have diffferent approaches regarding the use of hybrid contracts in al-Rahn scheme. In the light of that, this article aims to lay out the two countries’ sides in responding to the issue at hand. This qualitative study relies on secondary data and employs conceptual and comparative approach. It investigates the policies relating to hybrid contract in the implementation of al-Rahn both in Malaysia and Indonesia. This study indicates that academics in both countries tend to state that the hybrid contracts in al-Rahn are not in accordance with the Sharia. The non-compliance with the Sharia prompted Malaysia to create a new policy, namely by utilising the concept of Tawaruq. Meanwhile, Indonesia recently still associates Ijārah contracts as part of the implementation of al-Rahn.
