An Accountability Myth: A Critical Analysis On High-Stakes Testing In U.S. Schools, Noelle E. Haskell
An Accountability Myth: A Critical Analysis On High-Stakes Testing In U.S. Schools, Noelle E. Haskell
Journal of Multicultural Affairs
High-stakes testing has become synonymous with the United States (U.S.) education system. This began in the early 1900’s through the form of intelligence testing which was developed by several U.S. psychologists. Since then, high-stakes testing has taken on many forms. Popular policies such as No Child Left Behind (NCLB), Race to the Top, and the Every Student Succeeds Act (ESSA) have all taken aim at increasing academic achievement and holding schools accountable through high-stakes, standardized tests. Even through its varying forms, high-stakes tests have continued to perpetuate inequalities. Considering this, the current study examines how the rhetoric used in describing …

QPIE, SUBSTRATE COHERENCE, AND THE END OF PSYCHOLOGICAL DECOHERENCE
Humanity stands at an inflection—an energetic, cognitive, and civilizational hinge—where the old psychological architectures that governed the last ten thousand years are showing their limits. For millennia, societies relied on dualistic sorting mechanisms: good versus evil, winner versus loser, right versus wrong, gifted versus mediocre. These categories simplified administration, myth, and power. But simplicity came at a cost: chronic decoherence, adversarial internal narratives, fragmented social dynamics, and a deep systemic friction that progressively calcified into institutions, economies, and identities.

I. Introduction — What This Is and Why It Matters
The history of modern science is a story of disconnection: of separating objects from context, atoms from waves, systems from observers, and meaning from measurement. What was once referred to as “aether,” “field,” or “substrate” became fragmented language or metaphor — useful in calculation but forbidden in ontology.
This avoided question — what is the medium of reality itself? — created not clarity, but blind spots. Physics became powerful, yet incomplete. It described behavior …

Multipacking On Graphs And Euclidean Metric Space, Sk Samim Islam
Multipacking On Graphs And Euclidean Metric Space, Sk Samim Islam
Doctoral Theses
A multipacking in an undirected graph G = (V,E) is a set M ⊆ V such that for every vertex v ∈ V and for every integer r ≥ 1, the ball of radius r around v contains at most r vertices of M, that is, there are at most r vertices in M at a distance at most r from v in G. The multipacking number of G is the maximum cardinality of a multipacking of G and is denoted by mp(G). The MULTIPACKING problem asks whether a graph contains a multipacking of size at least k.

Fine-Tuning Llama2 For Summarizing Discharge Notes: Evaluating The Role Of Highlighted Information, Mahshad Koohi Habibi Dehkordi, Yehoshua Perl, Fadi P. Deek, Hao Liu
School of Computing Faculty Scholarship and Creative Works
This study investigates whether incorporating highlighted information in discharge notes improves the quality of the summaries generated by Large Language Models (LLMs). Specifically, it evaluates the effect of using highlighted versus unhighlighted inputs for fine-tuning LLaMA2-13B model for summarization tasks. We fine-tuned LlaMA2-13B in two variants using MIMIC-IV-Ext-BHC dataset: one variant fine-tuned with the highlighted discharge notes (H-LLaMA), and the other on the same set of notes without highlighting (U-LLaMA). Highlighting was performed automatically using a Cardiology Interface Terminology (CIT) presented in our previous work. H-LLaMA and U-LLaMA were evaluated on a randomly selected test set of 100 discharge notes …

Psoriasis is an inflammatory skin disorder driven by abnormal immune activation that promotes excessive proliferation and accelerated turnover of epidermal keratinocytes. IL-17 and TNF pathways are well known in psoriasis, but the other mechanisms that keep the disease active and link it to systemic comorbidities are not yet fully understood. A combined transcriptomic and systems biology framework was applied to map regulatory circuits in psoriatic lesions and to identify phytochemical candidates capable of multi-target modulation for topical intervention. Differential gene expressions between lesional and healthy skin was analyzed, followed by pathway enrichment, upstream regulator inference, protein-protein interaction network, and chemical-gene …

Advancements In Perfect Matchings Within Neutrosophic Fuzzy Graphs: Theory And Applications, Muhammad Saeed, Fatima Razaq
Advancements In Perfect Matchings Within Neutrosophic Fuzzy Graphs: Theory And Applications, Muhammad Saeed, Fatima Razaq
Neutrosophic Systems with Applications
Graph theory has been widely used in exemplifying relational structure, and a greater generalization to fuzzy and neutrosophic space enables the exemplification of uncertainty, indeterminacy, and inconsistency in complex systems. Some of these extensions include the neutrosophic fuzzy graphs that provide a more detailed description of the loose relations between the vertices and the edges. However, unlike in classical graph theory, where the concepts of matching and perfect matching are well developed, very little has been studied on how the two concepts can be extended to neutrosophic fuzzy graphs. To seal this gap, the current paper develops and defines the …

Mixed Linear Equation–Inequality Systems Over The Pura Vida Neutrosophic Algebra, Muhammad Rayyanu Abdullahi, Abdulhadi Aminu
Neutrosophic Systems with Applications
This paper proposes a neutrosophic extension of max-plus algebra for solving mixed systems of linear equations and inequalities.Classical max-plus algebra is a powerful tool for modeling synchronization in discrete-event systems LastNatpreClose LastNatClose, but it assumes fully deterministic data.To incorporate uncertainty and indeterminacy, we reformulate the framework so that coefficients and variables are expressed as neutrosophic numbers
γ+λI,γ,λ∈ℝ,I∈[0,1],
where I quantifies the degree of indeterminacy.
We redefine the max-plus semiring in this neutrosophic setting, extend solvability and uniqueness results, and adapt the ONEMLP-EI algorithm LastNatpreClose LastNatClose to handle neutrosophic …

The Inconvenience Doctrine, Alexi Pfeffer-Gillett
BYU Law Review
In a nation of stark inequalities, the Roberts Court is often portrayed as siding with the wealthy and powerful. Many scholars argue that the Court has abandoned legal principles altogether and instead simply chooses winners and losers based on the conservative majority’s political agenda. Meanwhile, scholarly examinations of the legal reasoning underlying the Court’s most impactful decisions are largely confined to specific subject areas. Such compartmentalized analyses, though, overlook broader patterns in the Court’s rulings that transcend substantive legal boundaries.
This Article bridges the gap in these parallel conversations by connecting the Roberts Court’s reasoning across many legal fields with …

Neutrosophic Σ - Baire Spaces, R. Vijayalakshmi, F. Josephine Daisy, M. Simaringa
Neutrosophic Systems with Applications
A Neutrosophic Baire Space extends the concept of Baire Space from classical topology to the realm of neutrosophic topology which deals with sets and spaces where truth, falsehood and indeterminancy are explicitly considered. In this paper the concept of neutrosophic σ - baire spaces are introduced in Neutrosophic topological spaces. Also Neutrosophic σ - dense, Neutrosophic σ - nowhere dense, Neutrosophic σ -first category and Neutrosophic σ - second category sets are defined. Several characterizations of neutrosophic σ - baire spaces are investigated and explained using examples and the conditions under which a neutrosophic topological space becomes a neutrosophic σ …

Integrating Mcdm Techniques For Optimized Task Offloading In Multi-Uav- Enaled Mobile Edge Computing System, Amira Salam
Neutrosophic Systems with Applications
Carefully choosing a task offloading strategy is crucial for optimizing task scheduling and offloading strategies in a multi-UAV system. Regarding cost, responsiveness, scalability, and data security, each strategy has pros and cons. As a result, selecting the best offloading technique is essential to multi-UAV mobile edge computing task scheduling optimization. A methodical and well-informed decision-making process accomplishes this.
The current study introduces a new hybrid methodology for the multi-criteria decision-making (MCDM) model, known as IVNs-DEMATEL-ANP-VIKOR. The purpose of this model is to find and choose an efficient task offloading strategy. With this method, we use IVNs-DEMATEL to show how different …

An Algorithm For Extracting Bathymetry From Icesat-2 Data That Employs Structure And Density Using Concentric Ellipses, Yuri Rzhanov, Kim Lowell
Faculty Publications
The ICESat-2 satellite collects LiDAR data along linear orbital tracks using a photon-counting green wavelength (532.27 nm) instrument. The utility of combining ICESat-2 data with satellite imagery for training and subsequently applying satellite-derived bathymetry models to provide estimates of shallow water depth is well-established. However, automating and improving the accuracy of the identification of ICESat-2 photon events (PEs) representing bathymetry remains a challenge. This article presents an algorithm for automated extraction of PEs reflected from the ocean floor (rather than the ocean surface or noise in the water column). The algorithm is unique in examining both the density of PEs …

Cache-Conscious Sparse Matrix Dense Matrix Multiplication On Gpus, Haoqiang Guo
LSU Doctoral Dissertations
Over the past decade, high-performance deep learning has evolved into a critical research domain, driven by the demand for efficient models and high inference throughput. Deep learning architectures have shifted from stacked convolutional layers to transformer-based models, while pruning techniques and graph-structured data have established sparse matrix–dense matrix multiplication (SpMM) as a fundamental kernel—particularly in graph neural networks (GNNs). Modern GPUs, with their massive parallelism and high-bandwidth memory, offer immense potential for accelerating these workloads. While SpMM implementations using the compressed sparse row (CSR) format remain common to avoid conversion overhead, preprocessing-based methods have recently demonstrated superior potential. In GNN …

Before a drug can be widely used, it must go through a long development process, starting from the discovery of the active ingredient and continuing with tests to confirm its safety and effectiveness. In this study, new olsalazine derivatives were synthesized, containing a fused morpholine-3-one ring and two five-membered heterocyclic rings (thiadiazole and oxadiazole). Common and readily available materials, such as salicylic acid (to prepare 2-hydroxy-5-nitrobenzoic acid) and inexpensive catalysts, were used to synthesize compounds from the first, 5,5'-(diazene-1,2-diyl)bis(2-hydroxy-3-nitrobenzoic acid) (A1), to the seventh, 6,6'-(diazene-1,2-diyl)bis(N-(4-(5-amino-1,3,4-oxadiazol-2-yl)phenyl)-3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-8-carboxamide) (A7).
Each compound was characterized by FT-IR and ¹H-NMR spectroscopy, along with physical properties such …
