Hybrid Vision Transformer–Cnn Framework For Alzheimer’S Disease Cell Type Classification: A Comparative Study With Vision–Language Models, Md Easin Hasan, Md Tahmid Hasan Fuad, Omar Sharif, Amy Wagler

School of Mathematical & Statistical Sciences Faculty Publications

Accurate identification of Alzheimer’s disease (AD)-related cellular characteristics from microscopy images is essential for understanding neurodegenerative mechanisms at the cellular level. While most computational approaches focus on macroscopic neuroimaging modalities, cell type classification from microscopy remains relatively underexplored. In this study, we propose a hybrid vision transformer–convolutional neural network (ViT–CNN) framework that integrates DeiT-Small and EfficientNet-B7 to classify three AD-related cell types—astrocytes, cortical neurons, and SH-SY5Y neuroblastoma cells—from phase-contrast microscopy images. We perform a comparative evaluation against conventional CNN architectures (DenseNet, ResNet, InceptionNet, and MobileNet) and prompt-based multimodal vision–language models (GPT-5, GPT-4o, and Gemini 2.5-Flash) using zero-shot, few-shot, and chain-of-thought …

Staff Education To Reduce Compassion Fatigue In Acute Care Staff Nurses, Kamala C. Mcgee

Walden Dissertations and Doctoral Studies

Compassion fatigue (CF), burnout, and moral distress are common in high-acuity nursing environments, yet nurses are rarely taught how to recognize or manage these challenges. The guiding question for this staff education project was about whether education focused on CF and mindfulness-based coping strategies would improve nurses’ knowledge and attitudes in an acute care VA medical center. Posteducation results (n = 20) showed meaningful, statistically significant improvements. Familiarity with CF increased from baseline (M = 2.35; SD = 1.04) to post implementation (M = 3.75; SD = .91), t(19) = −5.085, p < .001. Confidence in recognizing CF in oneself improved from baseline (M = 2.6; SD = .875) to post implementation (M = 3.60; SD = .821), p = .004. Confidence in recognizing CF in colleagues increased from baseline (M = 2.40; SD = .821) to postimplementation (M = 3.15; SD = .671), p = .012. Agreement that seeking help is a sign of weakness decreased from baseline (M = 2.00; SD = .503) to postimplementation (M = 1.40; SD = .951), p = .024. Although perceptions of organizational support did not change, nurses reported greater use of mindfulness, peer support, and boundary setting, supporting nurse wellbeing and psychological safety. Several recommendations emerge from this project. CF education should be integrated into routine staff development, annual competencies, and onboarding for new nurses. By reducing stigma around seeking help and promoting peer awareness, this work supports fostering a workplace culture where all nurses feel safe, supported, and valued, a positive social change.

Anomalous Spontaneous Induction Of Magnetic And Electric Fields In Dense Quark Matter, Efrain J. Ferrer, Jose Miguel Perez-Fernandez

Physics & Astronomy Faculty Publications

In this paper, we will demonstrate that a dense quark-matter system in the dual chiral density wave (DCDW) phase behaves as a ferromagnet in the sense that its magnetic-field dependent magnetization remains different from zero even at 𝐵 →0. The corresponding permanent magnetization is a function of the baryonic chemical potential 𝜇, decreasing up to zero as 𝜇 increases in the range of intermediate densities (312  MeV⩽𝜇⩽342  MeV) and then increasing from zero in the higher density interval 490  MeV⩽𝜇⩽550  MeV. We will show that this system’s ability to generate permanent magnetization, together with the existence of the axial anomaly, …
