Abstract. Advances in high-performance parallel computing have significantly enhanced the speed of large-scale hydrological simulations. However, the diversity and rapid evolution of available computational systems and hardware devices limit model flexibility and increase code maintenance efforts. This paper introduces SERGHEI-RE, a three-dimensional, variably saturated subsurface flow simulator within the SERGHEI model framework. SERGHEI-RE adopts the Kokkos-based portable parallelization framework of SERGHEI, which facilitates scalability and ensures performance portability on various computational devices. Moreover, SERGHEI-RE provides options to solve the Richards equation (RE) with iterative or non-iterative numerical schemes, enhancing model flexibility under complex hydrogeological conditions. The solution accuracy of SERGHEI-RE is validated using a series of benchmark tests, ranging from simple infiltration problems to practical hydrological, geotechnical, and agricultural applications. The scalability and performance portability of SERGHEI-RE are demonstrated on a desktop workstation, as well as on multi-CPU and multi-GPU clusters, indicating that SERGHEI-RE is an efficient, scalable, and performance portable tool for large-scale subsurface flow simulations.

Published: January 2025

Abstract. With climate change expected to intensify the occurrence and severity of droughts, the impacts of the groundwater table (GWT) depth and capillary rise on topsoil moisture may become critical drivers of biological activity. Consequently, the GWT depth could influence topsoil carbon (C) mineralization. In this study, undisturbed 200 cm long soil columns with three different textures (loamy sand, sandy loam and silt loam) were subjected to two artificial GWT depths (−165 and −115 cm) in the laboratory. We examined (1) upward moisture flow by capillary action along the soil profile, specifically into the top 20 cm of soil, and (2) the effect of the GWT on the decomposition of an added 13C-enriched substrate (ryegrass) over a period of 10 weeks, with limited wetting events representing a dry summer. A 50 cm difference in the GWT depth (−165 vs. −115 cm) resulted in different topsoil moisture values for the sandy loam (31 % vs. 38 % water-filled pore space – WFPS) and silt loam (33 % vs. 43 % WFPS) soils. In the loamy sand soil, GWT-induced moisture differences appeared only up to 85 cm above the GWT. The expected acceleration of the mineralization of the added ryegrass under a shallower GWT was not confirmed. In contrast, CO2 efflux pulses after some of the wetting events were even higher for the drier −165 cm GWT than for the −115 cm GWT across all three soil textures. Additionally, a model fitted to cumulative ryegrass mineralization showed a lower mineralization rate for the stable Cryegrass pool in the silt loam soil with the shallowest GWT, where capillary rise contributed most significantly to topsoil moisture, compared with other combinations of soil texture and GWT depth. These findings suggest that the upward capillary moisture flow, along with the resulting increase in topsoil moisture and the anticipated enhancement of biological activity and ryegrass mineralization, might have been counteracted by other processes. One possible explanation could be that rewetting may have triggered a stronger mineralization response, commonly known as the Birch effect, in drier topsoils compared with conditions in which the soil remained consistently wetter with a shallower GWT level. Based on our findings, inclusion of the process of texture-specific capillary supply from the GWT is required to adequately simulate moisture in the topsoil during droughts as they occurred over the past summers in northwestern Europe, depending on the GWT–texture combination. However, the net effect on topsoil C mineralization is complex and warrants further investigation, including the integration of processes related to fluctuations in soil moisture following rewetting.
Frequency anomalies and characteristics of extratropical cyclones during extremely wet, dry, windy, and calm seasons in the extratropics
Authors: Binder Hanin , Wernli Heini 
Published: January 2025

Abstract. Extreme meteorological seasons are highly relevant because of their severe impacts on many socioeconomic sectors. However, a global statistical characterisation of observed extreme seasons is challenging because at any specific location, very few such seasons occurred during the limited period with available reanalysis datasets. This study therefore uses 1050 years of present-day (1990–1999) climate simulations of the Community Earth System Model Large Ensemble (CESM-LE) and 71 years (1950–2020) of ERA5 reanalyses to systematically identify extremely wet, dry, windy, and calm seasons in the extratropics during winter and summer and to quantify the role of extratropical cyclones in their occurrence. Extreme seasons are defined as spatially coherent regions of extreme seasonal mean precipitation or near-surface wind. The results from the climate model and from ERA5 are mostly consistent, suggesting that the climate model captures the cyclone properties reasonably well. Compared to the climatology, extremely wet seasons are associated with positive anomalies in cyclone frequency in large parts of the extratropics. In the Southern Hemisphere (SH) storm track and at the downstream ends of the Northern Hemisphere (NH) storm tracks, cyclones contributing to wet winters are also anomalously intense and typically originate unusually far to the west and south, while in the subtropical North Atlantic and over the eastern Mediterranean, they are on average more stationary than in the climatology. Windy seasons are often associated with anomalously few but particularly intense cyclones, especially during winter. Positive anomalies in both cyclone frequency and intensity are found in the southern North Atlantic during winter, which suggests that windy winters in this region occur during southward shifts in the position of the main storm track. The patterns of dry and calm seasons mainly contrast with those of wet and windy seasons; i.e. they are often characterised by particularly few or weak cyclones or a combination thereof. In all four types of extreme seasons, there is remarkably large spatial and seasonal variability in the cyclone properties, especially over the continents. Overall, it can be concluded that (i) anomalies in the seasonal frequency and/or intensity distribution of extratropical cyclones are crucial for the occurrence of many extreme seasons in the extratropics and (ii) this link shows substantial geographical and seasonal variability.
Fuzzy Baer Subrings: A Fuzzified Extension of Baer Rings
Authors: Dinesh Kute  
Published: January 2025

In classical ring theory, a ring is classified as a Baer ring if, for any subset the left (or right) annihilator is generated by an idempotent element in This paper introduces the concept of fuzzy Baer subrings, extending the principles of Baer rings to the fuzzy setting by defining a fuzzy subset generated by an element and utilizing fuzzy left and right annihilators. Additionally, we develop the theory of fuzzy Rickart subrings by introducing the concept of fuzzy points, establishing that each fuzzy Baer subring inherently qualifies as a fuzzy Rickart subring. Further contributing to fuzzy algebra, we define fuzzy idempotent subrings, capturing broader generalizations in the fuzzy context. This research bridges classical and fuzzy set theories by adapting Baer rings, Rickart rings, and idempotent rings within the framework of fuzzy algebra.
Blockchain Technology Based Traceable and Safe Pharmaceutical Supply Chain Framework: An Effective Method for Searchable Pharma Chains
Authors: Vijay U. Rathod  
Published: January 2025

The paper explores the potential applications of emerging technologies to develop a blockchain-constructed pharmaceuticals supply chain traceability organization. In essence, a blockchain-based medication tracking system is vital for both government regulation and corporate operations. A reliable drug traceability system would make it simple for patients and those working in the drug supply chain to determine where the drug disappeared or has been. The drug traceability system is designed according to a number of concepts. First and foremost, the blockchain system for drug traceability must to accurately represent the supply chain's actual drug transaction logic, particularly with regard to drug-related data. Second, privacy and authenticity should be guaranteed by the drug traceability system. We propose Hyperledger Fabric, a potential blockchain-based decentralized architecture, to fulfill important medication traceability requirements, such as privacy, trust, openness, security, authorization and authentication, and scalability. We suggest, talk about, and contrast two possible drug traceability architectures: centralized and decentralized. We enumerate and discuss some open research questions related to medication tracking using blockchain technology. The pharmaceutical business can benefit from the suggested blockchain architectures.

Though helpful, traditional therapeutic approaches frequently have issues with participation and customized adaption This review systematically examines recent studies that utilize VR technology to address these limitations by providing interactive, immersive environments that can be tailored to each child's needs. Key findings from the literature indicate that VR-based interventions can significantly improve motor skills, coordination, and overall upper extremity function in these children. The review highlights various VR approaches, including game-based therapies and simulated tasksThe review concludes that while VR interventions show promising results Additional research is essential to enhance these therapies, comprehend their long-term effects, and tackle practical issues such as accessibility and affordability. The integration of VR into rehabilitation programs presents a progressive step forward in pediatric therapy, offering a dynamic tool to complement traditional methods and enhance the quality of life for children with hemiplegic cerebral palsy.
Power Dominator Coloring and Power Dominator Equitable coloring for Hierarchical Tree-Based Network Architecture
Authors: G. Navamani  
Published: January 2025

A power dominator coloring of a graph G is defined as a proper coloring where each vertex in V(G) power dominates every vertex within at least one color class. The minimum number of colors needed for a power dominator coloring of G is denoted as χ_pd (G). Furthermore, a proper coloring of a graph G is considered equitably k-colorable if the sizes of any two color classes differ by at most one, i.e. |(|C^i |-|C^j |)|≤1, 1≤i,j≤ k and the minimum number of colors needed for an equitable coloring of G is denoted as χ_e (G). The power dominator equitable coloring of a graph G defines a proper k-coloring where each vertex in V(G) power dominates all the vertices of at least one color class and also it satisfies the inequality |(|C^i |-|C^j |)|≤1, 1≤i,j≤ k and the minimum number of colors needed for a power dominator equitable coloring of G is denoted as χ_pde (G). In this study, we commence a research on this parameter and determine the power dominator equitable chromatic number χ_pde for certain hierarchical tree-based network architectures. The results are then compared with traditional domination concepts.

We explain a p – adic absolute value, non-archimedean axioms, after that we study their metric space and completion of X to XP.
Introduction: The p-adic numbers, where p is any prime number, originate from an alternate way of deﬁning the distance between two rational numbers. Kummer first discovered p-adic numbers in 1850. The p-adic numbers are useful because they provide another toolset for solving problems, one which is sometimes easier to work with than the real numbers.
Methods: the strong inequality of p-adic numbers, uniqueness theorem for p- adic number and also Ostrowski’s theorem for p-adic numbers.
Results: the absolute value p –adic metric is non-Archimedean, all triangles are isosceles in a non - Archimedean metric space, a non –Archimedean metric space theorem and completion of X to XP.
Conclusions: we have defined a p – adic number and p – adic metric. After that, we give their uniqueness and Ostrowski’s theorem.
Optimizing Crop Recommendations: A Novel IDCDMO-Enhanced ACGRU Approach for Advanced Agricultural Predictions
Authors: G.Rubia  
Published: January 2025

Agricultural productivity is maximised to a greater extent by crop recommendation. The traditional methods of crop recommendation are often rely on limited data, simple models, heuristic rules and expert knowledge which are less dynamic and not fully address the agricultural challenges. Deep Neural Networks (DNN) play an important role in crop recommendations by providing more accurate crops that are suited to the terrain. The research proposes a novel approach utilizing Attention based Convolutional Gated Recurrent Unit (ACGRU), neural network architecture for crop recommendation. Additionally it integrates Improved Distribution based Chaotic Dwarf Mongoose Optimization (IDCDMO) algorithm for feature selection. This study compares, for crop recommendation, to see the effectiveness of proposed approach. The performance of the IDCDMO¬¬-enhanced ACGRU is compared with ACGRU without feature selection and also with the conventional neural network models such as Feed Forward Neural Network (FNN) and Long Short Term Memory (LSTM). The IDCDMO-enhanced ACGRU significantly outperforming both the ACGRU without feature selection and conventional neural network models in terms of accuracy, precision, recall and f1 score. Therefore, the integration of IDCDMO with ACGRU efficiently enhances recommendation accuracy, improves soil health and adds greater agricultural productivity.

Authors: Zainab Abdulateef Rasheed  
Published: January 2025

Numerous scientific fields employ Kriging models (KMs) to study how physical systems behave. The computer code's response is interpreted by the KM as Gaussian process. A well-designed is an essential part of the KMs. Our study involves the design and analysis that is used in constructing KMs for computer experiments. Evaluating how design affects prediction accuracy is what we are interested in. Latin hypercube designs (LHDs) are commonly used for building KMs. We investigate many types of LHDs and assess their performances. We built many KMs based on different types of LHDs and the performance of each model is compared. The comparison is performed through some measures that test the KM performance. We apply KMs to the Robot Arm function as a real computer code.
