Continuous Ambient Microphone Calibration Via Opportunistic Broadband Auditory Icons, Rajeev Nongpiur, Chris Breithaupt

Defensive Publications Series

Performance drift in microphone arrays is often caused by environmental factors such as dust, moisture, and grime accumulating over time. This spectral mismatch degrades the performance of spatial audio algorithms that rely on precise array calibration. To address this limitation, a continuous calibration method is disclosed wherein broadband earcons are opportunistically played through device speakers. Audio responses are recorded by on-device microphones during defined user scenarios. A background model is generated to filter out environmental noise and room reverberation from these recordings. Subsequently, the filtered in-field measurement is compared against a reference factory template to estimate spectral deviation. A calibration …

3d Reconstruction Of Spatial Transcriptomics With Spatial Pattern Enhanced Graph Convolutional Neural Network, Chen Tang, Yuansheng Zhou, Xue Xiao, Lei Dong, Lei Yu, Guanghua Xiao

Faculty, Staff and Student Publications

Spatially resolved transcriptomics (SRT) is a promising new technology that enables simultaneous analysis of gene expression and spatial information for biomedical research. However, the existing statistical and deep learning algorithms used for analyzing SRT data rely solely on two-dimensional (2D) spatial coordinates, which limits their ability to accurately identify spatial domains, spatially variable genes (SVGs), cell-to-cell communications, and developmental trajectories in a three-dimensional (3D) spatial manner. To address these limitations, we introduced Spa3D, which utilized the anti-leakage Fourier transform and graph convolutional neural network model to reconstruct 3D-based spatial structures from multiple 2D SRT slices. We demonstrate that Spa3D is …

Examining The Impact Of Racial Microaggressions And Psychological Distress In Latine Individuals: A Focus On Ptsd, Anxiety, Depression, And Stress, Melanie Garcia, Yajairy Cabrales, Miguel A. Castano, Richard Chang, Gloria Wong-Padoongpatt

Spectra Undergraduate Research Journal

Latine individuals in the United States face distinct mental health challenges due to unique stressors, including systemic racism and discrimination. While research has established that racial microaggressions—such as daily slights, insults, and invalidations—negatively impact the psychological well-being of people of color, there remains limited scholarship specifically focused on Latine communities. This study examines different types of racial microaggressions—such as invisibility, criminality, and sexualization—as predictors of psychological distress among Latine individuals. A sample of 434 Latine participants completed measures assessing their experiences with racial microaggressions, as well as symptoms of depression, anxiety, stress, and trauma. Four multiple linear regression models were …

Quantitative Analysis Of Psychological Safety, Resilience, And Intraminority Solidarity As Predictors Of Racial Trauma Distress Among Bipoc College Students, Miguel A. Castano, Richard Chang, Gloria Wong-Padoongpatt

Spectra Undergraduate Research Journal

Racial trauma distress is when post-traumatic stress disorder symptoms occur due to repeated and cumulative experiences of racism and can negatively impact Black, Indigenous, and people of color (BIPOC). Consensus in research findings strongly suggests that BIPOC students are more likely to experience racism on university campuses than non-BIPOC students. To mitigate some of these negative outcomes, existing research has shown that psychological safety, resilience, and intraminority solidarity are protective factors for BIPOC students experiencing race-related distress. However, little is known about the frequency of racial trauma distress among BIPOC college students and how these variables may protect against racial …

Constitutional Time: The Temporal Dimension Of Precedent In Consitutional Jurisprudence, Laura A. Cisneros

University of Memphis Law Review

The role of time in constitutional precedent lies at the heart of judicial decision making. While there is a consensus on the importance of precedent, the modalities of its application remain a subject of intense debate within legal circles. At the core of this discourse lies a fundamental tension: the imperative to maintain fidelity to established precedent, thereby ensuring legal stability and predictability, versus the necessity to re-evaluate and potentially overturn precedent in response to evolving societal norms or innovative constitutional interpretations. This dichotomy presents a fundamental challenge to the Supreme Court, requiring a delicate balance between continuity and adaptability …

Data-Driven Prediction Of Superconducting Critical Temperature: A Linear And Regularized Linear Modeling Approach, Dipok Deb

Data Science and Data Mining

This study adopts a data-driven approach to estimate the critical temperature of superconducting materials using linear machine learning models. A comprehensive dataset derived from material physico-chemical properties was analyzed after systematic preprocessing and standardization. Three linear modeling strategies—Linear Regression, Ridge Regression, and Linear Regression with Subset Selection—were developed and evaluated using standard regression performance metrics. The findings demonstrate that both basic and regularized linear models can effectively capture the relationship between material features and superconducting behavior, offering robust and interpretable predictions. While feature selection enhances model transparency, it comes with a modest reduction in predictive capability. Overall, this work emphasizes …
