Frailty As A Framework To Understand Tuberculosis Severity, Recovery, And Sequelae, Yoscelina Estrella Martinez-Lopez, Benjamin W. Black, Jessica Lee, Brian J. Buta, Lisa Y. Armitige, William A. Fountain, Rafael Samper, Aanand D. Naik, Joanne Turner, Blanca I. Restrepo

School of Medicine Publications

Tuberculosis (TB) causes profound systemic illness, and many survivors experience long-term sequelae associated with disability and premature mortality. Current TB severity indicators capture isolated aspects of disease and may not reflect the integrated physiological impact of infection on the host. Frailty, a multidimensional syndrome characterized by reduced physiological reserve and increased vulnerability to stressors, predicts adverse outcomes and guides clinical management in geriatrics. We propose frailty as an integrative framework for understanding the systemic effects of TB across the life course, encompassing disease severity, recovery, and long-term sequelae. We discuss biological mechanisms through which Mycobacterium tuberculosis infection may erode physiological …

Focused ultrasound can be delivered through the temporal window to modulate heterogeneously located brain areas. Acoustic simulations allow for safety assessments when dynamically targeting brain structures, but the mismatch between simulation and measured focal pressure can vary across the steerable range due to mechanically inaccurate assumptions made about the skull and transducer. Here, we describe efficient methods for simulation-measurement calibration using axisymmetric projections and sparse sampling across a 3D steerable subspace encompassing deep brain targets across 157 subjects. To address the simulation-reality mismatch in skull transmission, we used the measured and predicted pressure values through eight human temporal window fragments …

Duncan NRI Faculty and Staff Publications

The metabolic importance of brown adipose tissue (BAT) has been recognized, but its origins, particularly supraclavicular BAT (scBAT), remain unclear. Here, we traced scBAT to Mef2c-anterior heart field (AHF)-marked cells. Mef2c-AHF-marked cells isolated from scBAT can spontaneously differentiate into brown adipocytes, express mesenchymal stem cell markers, and can be isolated from the stromal-vascular fraction (SVF) of wild-type scBAT as [CD31

Palmnet: Confidence-Calibrated Edge-Cloud Ai For Field Diagnosis Of Date Palm Diseases, Muntadher Kareem, Raed Majeed

Beyond Screening: Using Multiple Sources Of Evidence To Inform Early Literacy Instruction, Cheryl Kahn

The Reading Professor

Educators today collect more literacy data than at any previous point in history, yet many students continue to experience reading difficulties that are identified far later than they should be. This article argues that the problem is not a lack of information but a failure to integrate available evidence to prompt timely instructional action. Drawing on research in reading development, early identification of reading difficulties, teacher knowledge, assessment literacy, instructional decision-making, and responsive literacy instruction, this article proposes the Multiple Sources of Evidence Framework to strengthen early literacy decision-making. Rather than relying on any single assessment or screening result, the …

Techniques For Handling Unstable Agents In Agent-Based Networks, Ashwini S Kulkarni, Sushmitha Vatsal, Priyanka Bansal, Vivek Kumar Singh, Ghulam Ghaus Arshi

Defensive Publications Series

Proposed herein are a system and techniques that facilitate stability-aware metadata synchronization in agent-based networks. The system includes a closed-loop adaptive stability orchestration layer that utilizes a time-sensitive exponential-decay mechanism and historical recovery telemetry to dynamically tune suppression and reuse thresholds, thereby reducing control-plane churn and cascading failures. Rather than relying on binary health checks, the system uses a time-weighted stability score to support granular, policy-driven agent lifecycle management.

The Everyday Monument: Architectural And Spatial Transformations Of Rome's Nasoni, 1874–Present, Sandra L. Santos

McNair Summer Research Program

Rome's nasoni are small public drinking fountains that have provided free water throughout the city since 1874. There are approximately 2,500–2,800 nasoni in Rome, actively supplying people with free drinking water. Although they are usually understood as ordinary and mundane hydraulic infrastructure, their persistence across different political periods makes them useful objects for examining the relationship between architecture, public service, and political meaning. This research asks how the forms, materials, and spatial contexts of late-nineteenth-century nasoni differed from fountains constructed or modified during the Fascist era.

Over my three weeks of fieldwork in Rome, I documented seventy-five public drinking fountains …
