Cerebellar volumetric changes are intricately linked to aging, with distinct patterns across its transverse zones, the functional subdivisions characterized by unique cytoarchitectural and connectivity profiles. Despite research efforts, the cerebellar aging process in health and neurological disorders remains poorly understood. In this study, we investigated the effects of age and sex on total cerebellum, transverse zone, and lobule volumes using MRI data from over 45,000 participants compiled from six neuroimaging datasets. We also propose a framework for estimating cerebellum age as an indicator of cerebellar health. Significant age‐dependent volume reductions were observed across transverse zones, with the …

The New Urban Agenda published by UN-Habitat establishes that SDG 11 urges governments to protect the world's urban and natural cultural heritage, setting forth soft measures aimed at culture and education. Among these, it promotes the safeguarding of tangible and intangible cultural heritage, including the use of new technologies, and emphasizes the preservation of local heritage in the face of the current process of global acculturation. Simultaneously, the European Commission’s Recommendation (EU) 2021/1970 states that heritage is a key element in building European identity and encourages Member States to continue their efforts to digitize and preserve Digital Cultural Heritage assets. …
Robust Inference For The Unification Of Confidence Intervals In Meta-Analysis, Wei Liang, Haicheng Huang, Hongsheng Dai, Yinghui Wei
Robust Inference For The Unification Of Confidence Intervals In Meta-Analysis, Wei Liang, Haicheng Huang, Hongsheng Dai, Yinghui Wei
School of Engineering, Computing and Mathematics
Traditional meta-analysis assumes that the effect sizes estimated in individual studies follow a Gaussian distribution. However, this distributional assumption is not always satisfied in practice, leading to potentially biased results. In the situation when the number of studies, denoted as K, is large, the cumulative Gaussian approximation errors from each study could make the final estimation unreliable. In the situation when K is small, it is not realistic to assume the random effect follows Gaussian distribution. In this paper, we present a novel empirical likelihood method for combining confidence intervals under the meta-analysis framework. This method is free of the …

Let’S Talk About It: Utilizing A Code Blue Debrief For Inpatient Resuscitation Events, Brooke Blair, Jennifer Rice
2025 Henry Ford Jackson Hospital Research Symposium
Background: There is evidence to support the use of implementing clinical debriefing programs in the hospital setting. Implementing a standard debriefing program for teams that care for patients in cardiac arrest is shown to improve outcomes, yet in practice most events are not debriefed. Many hospitals currently use a debriefing tool for traumatic clinical events. However, many of these debriefing programs are focused on the Emergency Departments and pediatric events. Hypothesis: Utilizing a standard debrief tool for inpatient clinical resuscitation (Code Blue) events can identify areas for quality improvement. Methods: A literature review was performed including articles that related to …

Development And Evaluation Of Canbench: A Testbed For Assessing The Security Of Automotive Can Buses, Trevor S. Mcclellan
Development And Evaluation Of Canbench: A Testbed For Assessing The Security Of Automotive Can Buses, Trevor S. Mcclellan
Theses and Dissertations
Modern vehicles rely heavily on electronic control units (ECUs) that communicate via the controller area network (CAN) bus, a protocol developed in the 1980s with minimal security considerations. The growing number of ECUs has heightened the risk of cyberattacks on vehicles. Although CAN bus security has been extensively researched, the CAN standard still lacks built-in security measures. Furthermore, testing proposed security mechanisms is challenging due to the proprietary nature of automotive systems. To address this, an open-source physical testbed was developed using inexpensive, off-the-shelf components to support automotive CAN bus security research. The testbed provides a controlled environment for simulating …

Reservoir Characterization And Basin Modeling Of Mesozoic Siliciclastic Strata For Sedimentary Geothermal Exploration, Iron County, Utah, Theodore L. Morgan
Theses and Dissertations
The transition zone between the Colorado Plateau and Basin and Range provinces of southwestern Utah provides excellent opportunities for future geothermal resource development. A combination of large fault-controlled extensional basins with outcrop analogs along basin margins, an elevated heat flow and thermal regime and the presence of porous and permeable sedimentary formations within extensional sedimentary basins allow for sedimentary geothermal exploration and development. Utilizing a reservoir-centered approach has the potential to dramatically expand the economic limits of geothermal plays in both established and frontier basins. This study characterizes a sedimentary geothermal system in Iron County Utah, centered on the Escalante …

An ultra-high temperature ceramic based on ZrB2, TiB2, and SiC was hot pressed to full density at 1850 °C. Addition of 5 vol% of different metal-compounds, in the form of HfC, VC, NbC or CrB2, increased the densification temperature to 1910 °C. The resulting compositionally complex ceramics had homogeneous microstructures with boride grains exhibiting core-shell features. The shell was a solid solution containing variable amounts of the three metals. Notably, TiB2 remained as a discrete phase in the reference material and in the presence of the V- and Cr- based additions, whilst it dissolved into the main ZrB2-based grains for …

The Future Of Public Service Loan Forgiveness (Pslf) Under The Trump Administration, Arrianne Bautista
The Future Of Public Service Loan Forgiveness (Pslf) Under The Trump Administration, Arrianne Bautista
Cardozo Journal of Equal Rights and Social Justice (ERSJ) Blog
The earnings of public sector employees trail behind those of their private sector counterparts, and this income disparity is continually increasing. Thus, the burden of repaying student loan debt weighs heavily on public servants. Lower earnings, and the resulting difficulty in repaying student loans, tend to dissuade individuals from pursuing or maintaining careers in public service, thereby leading to staffing shortages in essential workforce sectors, particularly since those positions often require highly educated candidates. In 2007, Congress sought to address these burdens by passing the College Cost Reduction and Access Act (“CCRAA”), which established the Public Service Loan Forgiveness (“PSLF”) …

Mapping And Assessing High-Resolution Typhoon Exposure And Vulnerability In The Philippines: A Scoping Review, J. Andres F. Ignacio
Mapping And Assessing High-Resolution Typhoon Exposure And Vulnerability In The Philippines: A Scoping Review, J. Andres F. Ignacio
Journal of Management for Global Sustainability
This scoping review synthesizes the extensive literature on mapping high‑resolution typhoon exposure and assessing household and housing vulnerability in the Philippines. With approximately 20 typhoons passing through the Philippine Area of Responsibility annually—and seven to eight making landfall—the country faces enormous challenges that demand localized and granular risk assessments. Early approaches typically employed fixed‑buffer techniques to delineate exposure; however, recent research has shifted toward dynamic, multi‑hazard models incorporating real‑time meteorological data, numerical wind field and storm surge simulations, and advanced remote sensing imagery. Concomitantly, vulnerability assessments have evolved from indicator‑based composite indices to hybrid approaches that integrate quantitative household survey …
