Faculty, Staff and Student Publications

Introduction: List-learning tasks (LLTs) are important for characterizing memory in Alzheimer's disease and related dementias. However, as the Uniform Data Set Neuropsychological Battery (UDS-NB) historically did not require a specific LLT, centers have administered different LLTs. The newest UDS version (v4.0) requires one of two LLTs. To support harmonized UDS memory research, we developed a memory composite incorporating UDS memory tests and multiple LLTs.

Methods: Item-banking confirmatory factor analysis was applied to develop a memory composite in a diagnostically heterogeneous sample (n = 8716) that completed the UDS-NB and one of five LLTs. Construct validity was evaluated through associations with …

Air-Writing Recognition, Gaurang Shukla

Master’s Dissertations

Air-writing is the act of tracing characters or words in free space with a fingertip, recorded by a camera, giving a touch-free input modality for smart displays, augmented and virtual reality, and assistive interfaces. It is difficult because the finger never lifts: connecting strokes join adjacent letters with no pen-up signal to mark boundaries, and the same word varies widely in scale, position, and slant across writers. The WiTA benchmark of Kim et al. provides a large, person-disjoint dataset and a baseline that treats each clip as RGB video, recognised by a spatio-temporal 3D residual network trained with a CTC …

Simultaneous Tumor Delineation And Report Generation From Brain Mr Images, Adish Mallik

Master’s Dissertations

Brain tumor analysis is an important application of medical image computing, where accurate segmentation and interpretation of tumor regions can support diagnosis and treatment planning. However, existing methods often address tumor segmentation and radiology report generation as separate tasks. Moreover, one of the major challenges in report generation tasks from MRI is accurate tumor localization. Most models fail to locate the lobe and hemisphere in which the tumor is located, causing incorrect report generation. In this regard, a unified 3D vision-language framework is proposed for simultaneous brain tumor segmentation and report generation from multi-modal MRI. Given T1, T2, T1C, and …

Proteomic Analysis Of Ammonia-Induced Stress In Chinese Hamster Ovary (Cho) Cell Cultures, David Ryan, Michael Henry, Christiana Kondylo Sideri, Esen Efeoglu, Paula Meleady

Research Outputs: 2025-Present

Ammonia (NH₃) and its ionic form ammonium (NH₄⁺) are both metabolic waste products and essential nitrogen sources within Chinese hamster ovary (CHO) cell cultures. Although necessary for amino acid synthesis, excessive accumulation in the extracellular environment can exert stress, reducing cell proliferation and impairing the efficiency of recombinant protein production. Proper endoplasmic reticulum (ER) function is critical for CHO cells as biotherapeutic producers. Previous work has linked elevated ammonia concentrations to reduced productivity via altered N-glycosylation pathways, but its broader effects on ER biology remain unclear. In this study, we applied high-resolution mass spectrometry to perform a comprehensive …
