Coupling Mechanisms Of Fracture Propagation And Proppant Transport Indeep Coalbed Methane Reservoirs, Guo Xiaodong, Zhang Shicheng, Zhang Jingchen, Zhou Changjing, Zhang Chengsheng, Qiu Shixin, Xi Xiangrui

Coal Geology & Exploration

Objectives and Methods Deep coalbed methane (CBM) reservoirs commonly exhibit well-developed beddings, strong mechanical heterogeneity, and high in-situ stress gradients. These characteristics result in pronounced nonlinear fracture propagation and strong multi-field coupling effects during hydraulic fracturing. Consequently, it is challenging to accurately describe the mechanisms governing fracture complexity in deep coal reservoirs using conventional mechanical models for fractures. Using a super-large true triaxial system with dimensions of 2.0 m × 2.0 m × 1.0 m, this study conducted physical simulation experiments on hydraulic fracturing under varying injection rates and viscosities of fracturing fluids. In combination with fracture mechanics and energy …

The mechanisms behind both issues are associated with complex interplays between geological conditions and engineering disturbances. This study presents a systematic review of the current status of domestic and international research on the mechanisms of the solid-phase production, as well as relevant prevention and control methods. Furthermore, future research directions are proposed.Advances The solid-phase production in hydraulically fractured CBM wells essentially arises from flow-solid-chemical multi-field coupling processes under interplays between geological conditions and …

Predicting The Risk Of Water-Sand Inrushes From Coal Seam Roofs Based On A Small-Size Sample Dataset, Zhang Wenquan, Li Zixu, Zhu Xianxiang, Qiu Wei, Zhang Chengjie

Coal Geology & Exploration

Objective The eastern and northern regions of China exhibit thick unconsolidated layers and thin bedrocks, with water-sand inrush disasters occurring frequently. Therefore, accurately predicting the risk of water-sand inrushes from coal seam roofs holds great significance for safe coal mining. However, the water-sand inrushes in these regions exhibit complex disaster-causing mechanisms, which involve the coupling effects of multiple factors. Accordingly, the real-time prediction of the water-sand inrush risk in the field poses challenges including high risk and cost. These issues lead to difficult data acquisition and severely insufficient samples, limiting the accuracy and performance of traditional prediction models. Therefore, there …

A Dynamic Prediction Method For Coal Seam Thickness Based On The Kpca-Pso-Svr Model, Yang Tun, Ye Shugang, Ma Ming, Wang Qianyao

Coal Geology & Exploration

This will help ensure safe and efficient coal mining in coal mines. In coal seam thickness prediction, the comprehensive multi-attribute analysis method faces challenges such as the cumbersome selection of optimal seismic attributes and the low predictive accuracy of regression models. To address these challenges, this study proposed a support vector regression (SVR) prediction model based on kernel principal component analysis (KPCA) and particle swarm optimization …

Positive And Negative Pressure Distributions And Gas Migration Mechanisms Under Gas Drainage From Coal Seams Using Ultra-Long Directional Boreholes, Li Quanxin, Zhao Yuechen, Mou Quanbin, Wang Liang, Fang Jun, Wang Chenghao

Coal Geology & Exploration

Background Gas drainage via ultra-long directional boreholes plays a significant role in gas control in coal mines. To ensure safe and efficient gas drainage using these boreholes, it is critical to determine the mechanisms behind positive- negative pressure coupling, as well as the dominant mechanisms governing gas migration. However, the evolutionary patterns of positive-negative pressure zoning within the boreholes and the primary factors influencing gas drainage efficiency have yet to be accurately characterized. Methods Under the engineering background of the Shendong Baode Coal Mine, this study developed a multi-field coupling model integrating diffusion, seepage, and in-borehole flow fields based on …

Mechanical Performance Of Equilateral Triangular Lattices: The Role Of Nodal Fillets, Fakhreddin Emami, Andrew J. Gross

Faculty Publications

Triangular lattices are widely employed for their high strength to weight ratios, yet their mechanical performance is sensitive to geometric features, particularly the nodal geometry. This study investigates the influence of nodal geometry on the mechanical behavior of equilateral triangular lattices across a broad range of relative densities using high fidelity finite element simulations. We characterize the elastic properties, and strength limits as functions of fillet radius. Our results confirm the expected trend that, in stretching-dominated lattices with low relative density, the introduction of fillets reduces both stiffness and buckling resistance. In contrast, at higher relative densities, filleted nodes can …

Panic Disorder Treated With Individualised Homoeopathic Medicines: A Case Series, Hima Bindu Ponnam, Gr Kiranmayee Rompicherla

Indian Journal of Research in Homoeopathy

Introduction: Panic disorder is one category of generalised anxiety disorder that is commonly reported in a majority of the outpatient departments of primary care hospitals, especially in the COVID-19 post-pandemic era. Although its prevalence is lower compared to other anxiety disorders, panic disorder remains a serious concern, as it often leads to cardiorespiratory emergencies; therefore, prompt recognition and timely management are crucial. Since the first-line pharmacological interventions of modern medicine are expensive and associated with certain undesirable side effects, the homoeopathic system of medicine appears to be a safer and more economical alternative in such cases. Keeping this in view, …

Multi-Modal Tensor Fusion For Alzheimer’S Disease Recognition, Mason Li, Tiffany Le, Jiajing Huang, Yuxin Wen

Engineering Faculty Articles and Research

Accurate and early diagnosis of Alzheimer’s disease (AD) is critical for effective intervention, disease monitoring, and patient care. Traditional diagnostic approaches rely on a single modality, such as clinical assessments, neuroimaging, or genetic markers, which may fail to capture the complex, multifaceted nature of AD. Multimodal learning has therefore been explored to integrate complementary information across data sources. However, conventional fusion strategies, including early feature concatenation and late decision-level fusion, often model modalities independently and fail to capture high-order cross-modal interactions. To address these limitations, we propose a multimodal tensor fusion network (MTFN) that integrates heterogeneous data sources, including visual …

The Evolution Of Self-Awareness In Conscious Organisms, Robert A. Dielenberg

Journal of Conscious Evolution

Self-awareness in conscious organisms remains an enduring puzzle for philosophers and neuroscientists. This paper proposes a tripartite evolutionary model tracing its emergence through three sequential types: the sensory self (primitive egocentric, valence-tagged awareness of sensory states), the bodily self (external objectification of the body as a distinct entity, evidenced by mirror self-recognition in select species), and the cognitive self (internal objectification of the mind enabling recursive self-transformation). Adopting a monist framework, the model treats consciousness as the biological substrate of delayed neural apperception (the “Delayed Present”), within which selves emerge as increasingly sophisticated models. It distinguishes non-human metacognition—implicit, online regulation—from …

Spatial Narrative Beyond The Proscenium: Set Design As A Tool For Wellness, Christina Griffey

LSU Master's Theses

Inspired by a health crisis that led to spending time in medical settings, this thesis examines how our surroundings impact our well-being. By developing a framework that explores the topics of storytelling, space, place, theatre, and expanded scenography, I propose that set design can be used as a tool for wellness. I explore several disciplines through the lens of set design and highlight the disciplines, professionals, and designers that are contributing to the creation of therapeutic environments using scenographic practices.

New Statistical Distribution Smart1, Saad Naji Al-Azzawi, Mahmood A. Shamran, Aseel H. Ali

Baghdad Science Journal

This paper introduces a new nonclassical statistical distribution, SMART1, derived from a nonpolynomial function. This function is used in ecology to model population growth rates, in medicine to classify the relationship between activity and tumor volume in cancer, and in economics to analyze the relationship between supply and demand. The proposed distribution differs from the Gompertz distribution, which is fundamentally based on the exponential function. By contrast, the SMART1 distribution is constructed on principles of mathematical analysis, specifically through the identification of local maximum endpoints of the Gompertz growth function and the subsequent verification that the resulting function satisfies the …
