Black Hole Spectroscopy And Tests Of General Relativity With Gw250114, Jaclyn (Jax) Sanders

Physics Faculty Research and Publications

The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein’s general relativity (GR) in the high-velocity, strong-gravity regime and probe whether the remnant conforms to the Kerr metric. Upon perturbation, black holes emit a spectrum of damped sinusoids with specific, complex frequencies. Our analysis of the postmerger signal shows that at least two quasinormal modes are required to explain the data, with the most damped remaining statistically significant for about one cycle. We probe the remnant’s Kerr nature by constraining the spectroscopic pattern of the dominant quadrupolar (ℓ=m=2) …

Artificial Intelligence And Mental Health: Promise, Pitfalls And Ethical Priorities, Maharaj Singh

College of Nursing Faculty Research and Publications

Mental health conditions are prevalent across the lifespan, yet workforce shortages, long waiting times, and fragmented systems mean many people never receive timely, evidence‑based care. Artificial intelligence (AI), including machine‑learning classifiers and large language models (LLMs), is being explored to support earlier detection, closer symptom monitoring and scalable psychoeducation. Early studies suggest AI can surface risk signals from language, sleep/activity traces and clinical notes; summarise complex records for clinicians; and deliver structured self‑help at scale. At the same time, safety, bias, privacy and accountability concerns remain salient.

Valuing Water Quality Using Benefit Transfer Methods, Robert Johnston, Klaus Moeltner, Stephen C. Newbold, Dennis Guignet

Economics

This article summarizes methods, prospects, and methodological questions for water quality benefit transfer. Benefit transfer is the use of welfare estimates from settings where original valuation research has been conducted to predict similar estimates for other settings, allowing quantification of benefits and costs when original valuation studies are infeasible. Water quality has been among the most researched areas of benefit transfer, in part due to requirements for benefit-cost analysis within policies and programs that affect surface and ground water. The article begins with a review of benefit transfer methods and characteristics of water quality that challenge transfer validity. We then …

Speaking Freedom: Black Liberation, Abolitionism, And Substantive Justice, Darren L. Hutchinson

Faculty Articles

Subordinate groups form social movements to contest societal norms and practices that sustain inequality. Social mobilization by subordinates can spark countermovements by privileged classes who perceive egalitarianism as a threat to their economic, political, and social power. Privileged-group countermovements often seek to suppress speech that challenges oppression, known as liberation speech. In the nineteenth century, defenders of enslavement suppressed “liberation speech” by legal and extralegal means in order to maintain Whites’ social dominance. Abolitionist resistance to speech suppression helped foster a culture of free speech that created a foundation for First Amendment doctrines developed in the twentieth century. Drawing from …

The Sequence (S) Index As A Marker Of Diminished Step-To-Step Transition Efficiency In Older Adults, Elham Alijanpour, Ashwini Kulkarni, Peter G. Adamczyk, Daniel M. Russell

Rehabilitation Sciences Faculty Publications

Introduction: Age-related declines in walking efficiency are often attributed to musculoskeletal and neuromuscular changes, yet the mechanisms underlying these inefficiencies remain poorly understood. One key contributor is the step-to-step transition (STST), during which the center of mass (CoM) is redirected between limbs. The Sequence (S) index quantifies the temporal overlap between push-off and collision forces during STST, with higher values indicating greater mechanical energy loss. This study investigated whether aging affects STST efficiency, as quantified by the S index, and examined the timing and impulse characteristics underlying observed differences.

Methods: Thirteen young and eleven older healthy adults walked at five …

Nonlinear Differences In Postural Sway Across Attentional Focus Conditions In Individuals With And Without Anterior Cruciate Ligament Reconstruction, Natalie L. Ferguson, Brian L. Cone, Christopher K. Rhea, Anne Beethe, Breanna Studenka

Rehabilitation Sciences Faculty Publications

BACKGROUND: The structure of variability in postural sway reflects the adaptability and health of the postural control system. Entropy quantifies this structure by measuring the regularity of repeated fluctuations over time. Although entropy has been used to examine sway in neurological populations, little is known about how sway complexity changes following anterior cruciate ligament reconstruction (ACLR). Attentional focus may also influence postural control, with external focus typically promoting more efficient and automatic regulation than internal focus.

AIM: To examine how attentional focus (internal vs. external) influences the structure of postural sway in individuals with and without ACLR.

METHODS: Forty-three participants …

Eeg Signatures Of Motor Development In Early Childhood: A Systematic Review, Sonia Khurana, Ashwini Kulkarni, Thomas C. Bulea, Hunter J. Bennett

Walking It Off: Habituation Of Gait At Virtual High Elevation, Kelly Poretti, Toby J. Ellmers, Christopher K. Rhea, Tiphanie Raffegeau

Rehabilitation Sciences Faculty Publications

Introduction: Fear and anxiety about falling can disrupt gait control, leading to activity restriction and increased fall risk in older adults. VR can be used to induce postural threat (e.g., by simulating high elevation settings) within a controlled environment, inducing fall-related anxiety and cautious gait (i.e. slower, shorter steps) in young and older adults. However, it is unknown how emotional and motor responses to VR postural threat habituate across time because existing studies feature short exposures (10 seconds or less). Before VR-induced postural threat can be translated into an intervention, it is critical to understand threat-related gait habituation across time. …

We-Making Through Technology: Social Cohesion And Virtual Adaptation In Community Arts Organizations For Artists With Idd During Covid-19 Pandemic, Yumi Shirai, Michelle Boulanger Thompson, Tamara Shetron

Rehabilitation Sciences Faculty Publications

COVID-19 public health restrictions disrupted in-person arts participation, increasing risks of social isolation and reduced community access. Prior research shows that many people engaged in home-based arts and cultural activities during lockdown, supporting emotional regulation, a sense of belonging, and social connection; however, little is known about how these shifts affected community arts organizations that serve artists with intellectual and/or developmental disabilities (IDD), a population disproportionately impacted by the pandemic and longstanding inequities. We examined how community-based arts organizations adapted programming for artists with IDD during the COVID-19 pandemic, including barriers and unanticipated outcomes relevant to equitable access and participation …

In Vivo Volumetric Visualization And Quantification Of Cumulus Expansion In Mice With Intravital Optical Coherence Tomography, Kohei Umezu, Frank J Brooks, Irina Larina

Faculty, Staff and Students Publications

Ovulation is preceded by a critical physiological process known as cumulus expansion, during which the cumulus cell layer surrounding the oocyte undergoes structural remodeling. Despite the recognized importance of this process for reproductive success, live quantitative imaging of cumulus expansion has not been previously achieved due to limitations of current imaging technologies for deeply located ovaries. In this study, we employed intravital optical coherence tomography for three-dimensional visualization of mouse follicles containing cumulus-oocyte complexes (COC) within the physiological context of the ovary, both ex vivo and in vivo. This method enabled time-lapse measurement of cumulus layer thickness and COC …

Eeg And Imu Gait Signal Processing: A Comparative Assessment Of The "Reza" Exponential Filter And Classic Filters, Reza Pousti, Daniel M. Russell, Derek C. Monroe, Christopher K. Rhea

Rehabilitation Sciences Faculty Publications

Noise degrades both EEG and gait signals, and classical IIR filters (Butterworth, Chebyshev, elliptic) involve trade-offs between passband flatness, ripple, and roll-off. This study compared a novel exponential "Reza" filter with these designs for neural and locomotor data. We analyzed an open-source mobile brain-body imaging dataset with EEG and gait data from 49 healthy adults (EEG: 256-channel, 512 Hz; IMUs: six APDM Opals, 128 Hz). EEG channels were grand-averaged and band-pass filtered at 0.5-50 Hz, while IMU axes were averaged and band-pass filtered at 0.5-5 Hz. The outcomes were signal-to-noise ratio SNR (dB) and band-integrated Welch PSD (EEG:0.5-50 Hz; IMU:0.5-5 …

Exposing The Work Of The Market Through The Case Of Alternative Provision For English School Students, Nick Pratt, Elizabeth Done, Sam Morahan

School of Law, Humanities and Social Sciences

Pupils in England who for some reason are not able to attend school often find themselves in Alternative Provision (AP). These are special arrangements designed to address their specific needs and help them return to mainstream schooling. AP involves a financial agreement between the provider and the organisation that commissions the provision and thus operates as an explicit form of education market in which educational services are traded directly for financial recompense. We report on a case study of one AP provider in the South-West of England undertaken over a one-year period which generated data through individual, semi-structured interviews and …

E-Profits: A Business-Aligned Evaluation Metric For Profit-Sensitive Customer Churn Prediction, Awais Manzoor, M. Atif Qureshi, Etain Kidney, Luca Longo

Research Outputs: 2025-Present

Retention campaigns in customer relationship management often rely on churn prediction models evaluated using traditional metrics such as AUC and F1-score. However, these metrics fail to reflect financial outcomes and may mislead strategic decisions. We introduce e-Profits, a novel business-aligned evaluation metric that quantifies model performance based on customer lifetime value, retention probability, and intervention costs. Unlike existing profit-based metrics such as Expected Maximum Profit, which assume fixed population-level parameters, e-Profits uses Kaplan–Meier survival analysis to estimate tenure-conditioned (customer-level) one-period retention probabilities and supports granular, per-customer profit evaluation. We benchmark six classifiers across two telecom datasets (IBM Telco and Maven …
