Conversion Relationships And Three-Dimensional Storage And Utilization Modes Of Four Water Resources In An Open-Pit Mining Area, Chen Tianci, Xu Zhimin, Sun Yajun, Fang Jie, Wang Qiangmin, Xiong Xiaofeng, Zhu Yuhao, Lu Zihan, Wan Fei

Coal Geology & Exploration

Background Open-pit coal mines in China are primarily distributed in arid and semi-arid regions such as Xinjiang and Inner Mongolia. However, the contradiction between coal mining and groundwater resource conservation is increasingly prominent in these regions. Specifically, a substantial amount of mine water inflow produced during coal mining tends to lead to the further loss of groundwater resources within the influence range of a mining area. Concurrently, the failure of efficient mine water storage intensifies the regional water shortage.Methods This study investigated a typical open-pit coal mine in eastern Inner Mongolia. Using methods such as field survey and sampling, …

An Experimental Investigation Of Federal Messaging On Public Support For Enforcement- And Treatment-Based Approaches For Opioid Overdose Prevention In South Carolina, Lídia Gual-Gonzalez, Hunter M. Boehme, Peter Baker, Melissa Nolan Ph.D., Mph

Faculty Publications

Background

As the opioid overdose crisis continues to produce excessive morbidity and mortality in the United States, government agencies have applied various approaches to prevent overdoses, including law-enforcement efforts (e.g., arresting people who use drugs, interrupting drug traffickers, etc.) and treatment-based approaches (e.g., naloxone, medications for opioid use disorder, etc.). Public perception and support of these approaches are relevant for informing policy, allocating resources, and effectively implementing community interventions to prevent drug-related harms.

Methods

Using an embedded informational survey design, we experimentally assessed whether public support for strategies to prevent overdose in South Carolina is influenced by language from federal …

Towards Scalable Taxi Demand Prediction, Yifei Shen

Lingnan Theses (MPhil & PhD)

Accurate taxi demand prediction is essential for optimizing urban mobility systems across varying spatial-temporal resolutions and data conditions. Scalable taxi demand prediction refers to the capability of forecasting models to adapt to different granularities of spatial and temporal data while maintaining prediction accuracy, a critical requirement for practical urban applications ranging from fleet management to transportation planning. However, two fundamental challenges impede this scalability: data sparsity and multi-resolution forecasting requirements. Data sparsity, particularly pronounced in high-resolution predictions where numerous regions exhibit minimal activity, significantly compromises model performance. Concurrently, different urban applications necessitate predictions at varying temporal and spatial granularities, requiring …

Engagement, Motivation, And Interest In K-12 Science Education, Neil T M Bailie

Masters Projects

Interest, motivation, and engagement amongst science students is declining. This decline is primarily due to a loss of interest, motivation, self-efficacy, and perceived utility value (Bathgate & Schunn, 2017; Britner, 2008; Kraft, 2017). With crucial topics such as climate change and the legitimacy of vaccines coming under scrutiny, it is vital for our society that we keep our secondary students actively engaged and motivated with the science that they are learning in the classroom (Kolenatý et al., 2024; Schlopsna & Scheersoi, 2024). The main goal of this project was to create a complete unit curriculum covering the topics of the …

Mixed Galerkin- Implicit Differences Methods For Solving Couple Nonlinear Parabolic System With Constant Coefficients, Wafaa Abd Ibrahim, Jamil A. Ali Al-Hawasy

Baghdad Science Journal

In this paper, the mixed Galerkin- implicit difference method (MGIFDM) is used to solve a couple of nonlinear systems of parabolic partial differential equations with constant coefficients which are abbreviated by (CNPSCC). At first the weak form of the CNPSCC is formulated and then it is discretized using the proposed method, the method mixes the Galerkin finite element method (GFEM) in space variables with the implicit finite difference method (IFDM) in time variables, so the method was named by MGIFDM. At any discrete time tj the method transforms the CNPSCC into a couple Galerkin nonlinear algebraic system (CGNAS), which is …

A Study Of The Atangana Baleanu Fractional Differential Equation With An Application In Gas Dynamic Problem, Amjad Shaikh, Shashikant Waghule, Dinkar Patil, Kottakkaran Sooppy Nisar

Baghdad Science Journal

This article presents an analytical approximation for the nonlinearity of the fractional order gas dynamics equation in both homogeneous and nonhomogeneous cases, with a particular emphasis on shock fronts. The approach utilizes the fractional differentiation operator proposed by Atangana and Baleanu. By employing this operator, an approximate solution for the fractional order gas dynamic equations in scenarios involving shock fronts is derived. The solution process primarily involves an iterative procedure that leverages the Laplace transform for numerical computations. The use of the Laplace transform minimizes round-off errors, resulting in a solution that is both precise and straightforward to implement. The …

Perception Of Quality Of Life, Brain Regions, And Cognitive Performance In Hispanic Adults: A Canonical Correlation Approach, Juan C. Lopez-Alvarenga, Jesus D. Melgarejo, Jesus Rivera-Sanchez, Lorena Velazquez-Alvarez, Rosa V. Pirela, John Blangero, Jose E. Cavazos, Michael C. Mahaney, Joseph D. Terwilliger, Gladys E. Maestre

School of Medicine Publications

The quality of life (QoL) perception has been studied in neurological diseases; however, there is limited information linking brain morphological characteristics, QoL, and cognition. Human behavior and perception are associated with specific brain areas that interact through diffuse electrochemical networking. We used magnetic resonance imaging (MRI) to analyze the brain region volume (BRV) correlation with the scores of Rand’s 36-item Short Form Survey (SF-36) and cognitive domains (memory and dementia status). We analyzed data from 420 adult participants in the Maracaibo Aging Study (MAS). Principal component analysis with oblimin axis rotation was used to gather redundant information from brain parcels …

Custom Thin-Coat Designs For Reflective Waveguides In Augmented Reality Wearables, Jun Yang, Alexander Koshelev, Christophe Peroz

Defensive Publications Series

The use of reflective waveguides in augmented reality (AR) displays can reduce see-through transmission, such that a person facing the user can perceive an uneven brightness of the user’s face near the eye region. Uneven face brightness can cause some social and cosmetic discomfort. This disclosure describes a family of graded thin-film coats for reflective waveguides with multiple SKUs, each tailored to serve users of specific skin tone, color, and/or texture. The coating for the eye-pupil expander (EPE) and output coupler (OC) regions of the lens are tuned to achieve certain reflectance and wavelength-dependence criteria that render the prisms on …

Improving Large Language Models’ Summarization Accuracy By Adding Highlights To Discharge Notes: Comparative Evaluation, Mahshad Koohi Habibi Dehkordi, Yehoshua Perl, Fadi P. Deek, Zhe He, Vipina K. Keloth, Hao Liu, Gai Elhanan, Andrew J. Einstein

School of Computing Faculty Scholarship and Creative Works

Background: The American Medical Association recommends that electronic health record (EHR) notes, often dense and written in nuanced language, be made readable for patients and laypeople, a practice we refer to as the simplification of discharge notes. Our approach to achieving the simplification of discharge notes involves a process of incremental simplification steps to achieve the ideal note. In this paper, we present the first step of this process. Large language models (LLMs) have demonstrated considerable success in text summarization. Such LLM summaries represent the content of EHR notes in an easier-to-read language. However, LLM summaries can also introduce inaccuracies. …

Toups, Kevin E. Thorpe, Jiaxin Huang, Peng Huang

School of Medicine Faculty Publications

Background: Spinal cord injury (SCI) clinical trials typically rely on a single primary endpoint to assess drug efficacy. This strategy fails to adequately capture the full impact of treatment in heterogenous neurological conditions like SCI. A more patient-centric analysis requires assessment of neurological function, functional capacity, and quality of life, incorporating meaningful patient-reported outcomes. The global statistical test (GST) addresses this challenge using a unified statistical conclusion regarding the superiority of a treatment strategy over another by evaluating multiple trial endpoints simultaneously. Methods: The RISCIS trial (Safety and Efficacy of Riluzole in Acute Spinal Cord Injury Study) data was analysed …
