Bundled Guidance Types And Changes In Expected Volatility, Thaddeus Neururer, George Papadakis

University Research

We examine how different types of bundled managerial guidance affect uncertainty levels around earnings announcements. To measure changes in uncertainty, we use both changes in implied volatilities and methods that decompose the implied volatility term structure. Unlike prior studies, we find little evidence that earnings guidance is associated with investor uncertainty. Our results instead indicate that other forms of bundled guidance are associated with lower uncertainty levels. Revenue, capital expenditure, and earnings before interest, taxes, depreciation, and amortization guidance are strongly associated with reductions in investor uncertainty, even when firms provide earnings guidance.

Improving Equity Within The Holistic Admission Process Through Race-Neutral Holistic Review: A Before And After Cross-Sectional Study, Megan Eikenberry, Kylie Scott, Jaime González, Josh Subialka, Lacey Frankland, Patrice Ayala, Mark Kargela, Byron Russell

Physical Therapy Faculty Publications

Introduction: The US Physical therapist (PT) workforce lacks racial and ethnic diversity, which may contribute to health disparities. Holistic review (HR) admission methods may improve workforce diversity by evaluating applicants' academic metrics, experiences, and personal attributes. Holistic review processes must adapt following the 2023 Supreme Court ruling prohibiting race-based admission criteria.

Review of literature: Holistic review criteria are program-specific and align with institutional and programmatic goals. While HR is shown to improve student body diversity, most PT education programs heavily emphasize academic metrics, which may disadvantage racial and ethnic minority (REM) applicants from acceptance. This study examines the racial and …

Improvements In The Thermal Stability And Mechanical Robustness Of Holograms Recorded In Acrylamide/Polyvinyl Alcohol-Based Photopolymers Through The Use Of D-Sorbitol As A Plasticizer, Michael Murray, Aaron Byrne, Izabela Naydenova, Suzanne Martin

Research Outputs: 2025-Present

In this work, a photopolymer formulation is presented that demonstrates significant improvements in layer hardness and temperature stability, while retaining the excellent holographic recording characteristics and ease of preparation associated with acrylamide (AA)/polyvinyl alcohol (PVA)-based photopolymers. This is achieved through the use of N-phenyl glycine as an electron donor and, for the first time, D-Sorbitol, a naturally occurring sugar-alcohol, as a plasticizer. The plasticizing effect of D-Sorbitol is demonstrated through the minimal loss of diffraction efficiency (η) observed upon UV bleaching (fixing) of 500 lines/mm gratings, which is evidence for effective mass transport during holographic recording. This solves a key …

Temperature Dependence Of The Imaging Properties Of Holographic Lenses, Tomás Lloret, Jorge Lasarte, Suzanne Martin, Izabela Naydenova, Inmaculada Pascual

Research Outputs: 2025-Present

The demand for advanced photonic technologies to enhance augmented reality (AR) devices has led to a significant interest in new optical materials suitable for operation in sometimes challenging environmental conditions, such as elevated temperatures levels. Holographic optical lenses (HOLs), fabricated using holographic recording, offer several advantages over traditional refractive lenses, including greater versatility, lower cost, lower weight, and increased adaptability. In this study, we investigated the optical and thermal performance of HOLs recorded on four different photosensitive materials: Bayfol HX200, Bayfol HX120, a PVA/acrylamide-based photopolymer (AA/PVA), and a photopolymerisable hybrid sol–gel (PHSG). The lenses were exposed to thermal cycles 20 …

Background: Blood-based biomarker panels, including GALAD, have been proposed as an alternative to abdominal ultrasound for hepatocellular carcinoma (HCC) surveillance. Studies suggest longitudinal evaluation of biomarkers can improve test performance; however, no large studies have validated these findings.

Methods: We leveraged the HCC Early Detection Strategy (HEDS) study (n=1019 patients with cirrhosis; 99 incident HCC) and Texas HCC Consortium (THCCC) (n=2345 patients with cirrhosis; 126 incident HCC) to compare the performance of fixed-threshold GALAD (cutoff of -1.36), and 4 longitudinal algorithms: longitudinal GALAD, PALAD, mFB-ALAD, and mPEB-ALAD. The HEDS cohort was used to derive longitudinal algorithms, and external validation was …

The Evolving Therapeutic Landscape Of Pcsk9 Inhibition, Frederick J Raal

Faculty, Staff and Students Publications

Cardiovascular disease remains the leading cause of death worldwide with low density lipoprotein being a major, yet modifiable, risk factor. Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays a central role in regulating low density lipoprotein (LDL) receptor expression. Naturally occurring loss-of-function variants in the PCSK9 gene result in lifelong lower LDL cholesterol (LDL-C) levels and significantly lower risk of atherosclerotic cardiovascular disease (ASCVD), providing strong genetic validation of PCSK9 as a therapeutic target. This insight has driven the development of therapies directed at PCSK9 for the management of hypercholesterolaemia, particularly in patients who fail to meet LDL-C targets despite maximally …

Results: In the 20 participants with APOB/LDLR variants and complete data, low-density lipoprotein cholesterol (LDL-C) was numerically lower but not significantly different before …

Toward Scientific Rigor: Setting Standards For Indirect Calorimetry Analysis And Reporting

Faculty, Staff and Students Publications

Indirect calorimetry determines energy expenditure by measuring respiratory gas exchange. The approach is based on the principle that nutrient metabolism consumes O2 and produces CO2 and water in predictable ratios that can be compared with heat production. Due to the impracticality and high cost of direct calorimetry, indirect calorimetry is the major approach for modern metabolic studies in preclinical models. Despite the broad adoption of this method in rodent phenotyping, the field has lacked standardized methods for analyzing, representing, and sharing these data, limiting scientific progress. The recent review in Nature Metabolism by the International Indirect Calorimetry Consensus Committee (IICCC) …
