Chain Continuity & Multi-Master Keyframe Coverage- Two Methods For Edit-Ready Ai Filmmaking, John Trevino

Theatre Faculty Publications

Current AI video models generate short clips with inconsistent visual details across shots, preventing traditional film editing. A character may change clothing, lighting may shift, and spatial relationships may drift between angles—all of which break cinematic continuity (Bordwell, Thompson, & Smith, 2020). This paper formalizes Chain Continuity, a reproducible four-step method that eliminates these discontinuities by separating camera construction from performance generation. The method requires locking a single Master Key Frame taken from the first frame of the Master Shot, building all other camera angles as static Setup Frames derived only from that first-frame key, and then generating performances solely …

First-Principles Theory Of Five-And Six-Phonon Scattering, Yi Xia

Mechanical and Materials Engineering Faculty Publications and Presentations

igher-order phonon scatterings beyond fourth order remain largely unexplored despite their potential importance in strongly anharmonic materials at elevated temperatures. We develop a theoretical formalism for first-principles calculation of five- and six-phonon scatterings using Green’s function techniques based on a diagrammatic formalism, and systematically investigate multi-phonon interactions in Si, MgO, and BaO from room temperature to near melting points. Our calculations reveal dramatically different material-dependent behaviors: while five- and six-phonon processes remain negligible in Si even at high temperatures, they become increasingly important in MgO near its melting point (3100 K) and in BaO at intermediate temperatures (1200 K). Most …

Chronic Rhinosinusitis Is A Risk Factor For Interstitial Lung Disease In Sjogren’S Syndrome, Brian Schonewald, Christopher Xie, Andrew Engel, Ross Summer, Giorgos Loizidis

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

BACKGROUND: Interstitial lung disease (ILD) is a leading cause of morbidity and mortality in Sjögren's syndrome (SS), but its risk factors remain unclear. Although SS affects both the upper and lower respiratory epithelium, it is unknown whether this occurs simultaneously or separately. In other autoimmune conditions-such as eosinophilic granulomatosis with polyangiitis and granulomatosis with polyangiitis-upper airway disease precedes lower lung involvement by months or even years. We hypothesized that chronic rhinosinusitis (CRS), as an upper airway disease, may be a risk factor for ILD in SS.

METHODS: We analyzed the TriNetX Research Network database to compare incident ILD in SS …

Staff Education To Improve Phq-9 Depression Screening And Management In Primary Care, Elizabeth Ezeamaka

Walden Dissertations and Doctoral Studies

This Doctor of Nursing Practice staff education project aimed to improve staff knowledge and enhance the consistency in administering and interpreting the Patient Health Questionnaire-9 (PHQ-9) within a mental health clinical setting. The practice problem was significant because variability in PHQ-9 use resulted in unreliable depression screening data, potentially leading to missed detection of depression or suicidal ideation, which undermines patient safety and quality of care. The guiding practice-focused question was: Among healthcare staff administering the PHQ-9, what effect does an educational program have on their knowledge related to the administration, documentation, and interpretation of depression screening? The purpose of …

Quantifying The Seasonal Dynamics Of A Transitional Ice Cliff-Pond System On A Debris-Covered Glacier, Zhen He, Matthew Westoby, Shaoting Ren, Chuanxi Zhao, Yifei He, Tianzhao Zhang, Wei Yang

School of Geography, Earth and Environmental Sciences

Ice cliffs and supraglacial ponds are key drivers of mass loss on debris-covered glaciers. However, the relationship between melt ponds and adjacent ice cliffs has not been fully explored. We investigated the seasonal drainage patterns of a melt pond on the debris-covered Zhuxi Glacier in southeast Tibet and estimated the mass loss of its adjacent ice cliff during 2023-2024. Using hourly time-lapse photogrammetry we built a series of high-resolution point clouds to quantify the evolution of the ice cliff-pond system. Our findings indicate that subaerial melting and undercutting were the primary mechanisms of ice cliff mass loss during summer. In …

Use And Reporting Of Intervention Mapping For Adaptation: A Systematic Review Protocol, Eunyoung Kang, Hugo R Sánchez-Blas, Elizabeth O Obekpa, Maria E Fernandez

Faculty, Staff and Student Publications

Introduction: Intervention adaptation is likely to occur to some extent when implementing interventions in new implementation contexts. Using systematic frameworks can guide intentional and effective adaptation processes. Intervention Mapping for Adaptation (IM-ADAPT) is a framework that offers step-by-step guidance for systematic, theory-based intervention adaptation. Despite the increasing use of IM-ADAPT, there is limited understanding of the contexts in which it has been applied and how effectively it is used and reported. Addressing this knowledge gap can improve current adaptation practices and inform future enhancements of the IM-ADAPT framework and the broader science of intervention adaptation. This review aims to (1) …

Developing A High-Throughput Machine Learning Screening Platform For Genetic And Pharmacological Modulators On Caenorhabditis Elegans Seizure Behavior, Paul A. Scarpinato

Electronic Theses and Dissertations 2020 - Present

Epilepsy is a chronic neurological disorder characterized by recurrent seizures that affect over 50 million people worldwide, including more than 3.5 million in the United States. Seizures arise from a disrupted balance between excitation and inhibition. Although antiepileptic drugs (AEDs) remain the primary treatment to restore the excitation and inhibition balance, approximately 30% of patients experience drug-resistant epilepsy, highlighting the need for additional antiseizure medications. The Caenorhabditis elegans electroshock assay was developed in relative alignment with the rodent maximal electroshock seizure (MES) test, the gold standard for preclinical AED screening, provides a cost-effective platform for prescreening candidate AEDs.
