Underclosed Posets, Richard Ngo

McNair Summer Research Program

Underclosed complexes are a recent generalization of interval graphs to higher dimensions. Motivated by underclosed complexes, we define and study underclosed posets. Order ideals of these posets correspond to pure underclosed complexes. We classify which principal order ideals are rank-symmetric (and in fact are self-dual).

Disentangling The Hemodynamic Effects Of A-Wave Loss And Cardiac Output Reduction In Atrial Fibrillation, Hailey Labonte, Ahmad Bshennaty, Ghasaq Saleh, Salameh Al-Halaseh, Mohamad Alkhouli, Hoda Hatoum

Michigan Tech Publications

Purpose: Atrial fibrillation (AF) increases thromboembolic risk, yet the relative hemodynamic contributions of A-wave loss, cardiac output (CO) reduction, and patient-specific atrial geometry remain incompletely understood. This study aimed to isolate the hemodynamic consequences of A-wave removal and CO reduction on left atrial (LA) flow and stasis. Methods: Five patient-specific LA geometries were evaluated using transient laminar CFD simulations. For each geometry, the sinus rhythm transmitral waveform was used as the baseline and modified to represent AF with compromised and conserved CO. Hemodynamic endpoints included LA velocity, time-averaged wall shear stress (TAWSS), relative residence time (RRT), oscillatory shear index (OSI), …

The Use Of Machine Learning Models For Predicting The Dielectric Strength Of Gases, Matthew Mileski, Paul W. Groth, Timothy S. Wolfe, Adib J. Samin

Faculty Publications

Technological advancements in high voltage systems have pushed sulfur hexafluoride (SF6) to its operational limits. Furthermore, this gas has other drawbacks including a high liquefaction temperature and a high global warming potential. Therefore, there has been an urgent need to find alternative gases with high dielectric strength (DS). In this work, density functional theory (DFT) is used to calculate molecular descriptors that are fed into an artificial neural network (ANN) and a random forest (RF). These machine learning (ML) models are then used to predict the DS for hundreds of molecules. A finite element model (FEM) is also used to …

Recalibrating Risk: A Call For South Asian-Focused Heart Failure Prediction Models, Nandini Nair, Dongping Du, Aiswarya J. Pillai, Swarna Mahesh, Mrudula R. Munagala, Howard J. Eisen, Balakrishnan Mahesh

Division of Cardiology Faculty Papers

Background: Heart failure (HF) represents the final common pathway of diverse cardiovascular disorders, including coronary artery disease, primary myocardial pathology, and abnormalities of cardiac conduction. These conditions arise from an interplay of genetic, environmental, and psychosocial influences, making it essential to understand these determinants to improve risk prediction and prevention. Multiple biological pathways of inflammation, fibrosis, coagulation, oxidative stress, lipid dysregulation, endothelial dysfunction, and metabolic disturbances are shaped by inherited susceptibility and modifiable exposures. Together, these mechanisms drive HF development and progression, though their relative contributions vary across populations. Methods: PubMed and Google Scholar were searched for clinical, biomedical, and …

Effective Visibility In The Infrared Bands, Peter L. Dean-Erlander, Steven T. Fiorino, Ronald G. Driggers

Faculty Publications

Visibility is an atmospheric metric for the comparison of terrestrial imaging conditions and locations. A limitation of visibility is that it is defined for the visible spectrum only, and there is no simple infrared equivalent. This study compares three reflective infrared wavebands: near-IR (NIR), shortwave IR (SWIR), and extended shortwave IR (eSWIR), to the visible band across a global set of cities to develop three rule-of-thumb functions for IR effective visibility. To accomplish this, a radiometric sensor model is combined with the Laser Environmental Effects Definition and Reference (LEEDR) software package to calculate the visibility of a black-and-white contrast target …

An Atmospheric Optical Turbulence Structure Parameter Measurements System Based On Direct Ri Sensing Using High-Resolution Fiber-Optic Sensors, Matej Njegovec, Simon Pevec, Vedran Budinski, Boris Macuh, Melissa K. Beason, Denis Onlagic

Faculty Publications

The paper presents a method to characterize the refractive index structure parameter (C_n²) associated with optical turbulence directly. The characterization system is based on miniature, high‑resolution, all‑fiber refractive index (RI) sensors. The refractive index sensors employ open‑path, low‑finesse Fabry–Perot interferometers that are approximately 8 mm long and 200 μm in diameter. The active part of the interferometers is made of ultra‑low‑expansion glass, which eliminates the influence of thermal expansion on the refractive index measurements. The proposed refractive index sensor, operating in a differential configuration, achieved a resolution of 2×10^-9 RIU using a custom‑designed spectral interrogation system …

Phenotypic And Biochemical Responses Of High-Yield Tomato Varieties To Salinity And Drought Stress, Shahida Ferdousee, Myung Hwangbo, Md Sakil Arman, Muhammad Abul Kalam Azad, Ajit Ghosh, Jongsun Kim

School of Earth, Environmental, & Marine Sciences Faculty Publications

Abiotic stresses can influence plant growth and productivity by causing physiological, biochemical, molecular, and morphological changes. Salinity and drought are increasing in frequency and intensity because of climate change. Therefore, this study assessed four high-yield tomato cultivars under 150 mM NaCl and 260 mM mannitol treatments to characterize physiological (i.e., chlorophyll level, root/shoot length, and relative water content) and biochemical responses (i.e., GLY I/II and DLDH enzyme activities, proline, and hydrogen peroxide). Results indicated that the four BARI tomato varieties showed genotype- and treatment-specific physiological and biochemical responses rather than a single uniform tolerance pattern. BARI tomato 2 maintained relatively …

A Case Report Of Myocardial Infarction Complicated With Blood Pressure Fluctuations Caused By Pheochromocytoma, Huiping Li, Wei Yang, Yu Feng, You Zhang, Gan-Xin Yan, Chuanyu Gao

Department of Medicine Faculty Papers

Pheochromocytoma typically presents with sustained or paroxysmal hypertension, but initial manifestation as acute non-ST-segment elevation myocardial infarction (NSTEMI) is rare. Peri-procedural hemodynamic fluctuations are often dramatic, making diagnosis and management challenging. We report a 51-year-old male admitted with chest tightness for 17 days. Elevated troponin and coronary angiography showing multivessel disease with total occlusion of the mid-left anterior descending artery (LAD) led to a preliminary diagnosis of NSTEMI. During percutaneous coronary intervention, blood pressure surged to 240/130 mmHg; intravenous nitroprusside caused an instantaneous drop to 95/55 mmHg, with rapid rebound to >200 mmHg upon withdrawal, showing no clear temporal relationship …

“Lost In Transcription?”: A Case Study Of Using Ai And Humans-In The Loop To Create Captions And Transcripts For A Library Symposium, Eva Lu, Sonya Panangaden, Mark Weiler, Michael R. Clark

Library Publications

In many regions, academic libraries are increasingly expected to generate recorded content as part of their services and operations, such as hosting public or academic events. These recordings require quality captions and transcripts to address the needs of users with disabilities as required by human rights legislation. Unfortunately, auto-generated captions cannot be relied upon to provide error-free outputs. This paper presents a case study of how we used AI and involved 35 volunteers from across North America to create captions and transcripts for recordings of a 3-day virtual accessibility symposium. This initiative was put in place to ensure all attendees …

E3 Ligase Rnf145 Regulates Airway Smooth Muscle Cell Proliferation Via The Pp2a-P70s6k Signaling Axis, Vijaya Kumar Gangipangi, Erin O. Curley, Deepak A. Deshpande, Pawan Sharma

Center for Translational Medicine Faculty Papers

Airway smooth muscle (ASM) is a key determinant of airway caliber and a major contributor to structural remodeling in obstructive lung diseases, including asthma and COPD. ASM proliferation is regulated by transcriptional and post-transcriptional mechanisms, including ubiquitin-dependent protein turnover mediated by E3 ubiquitin ligases. Here, we investigated the role of the RING-type E3 ligase RNF145 in mitogenic signaling and ASM cell proliferation. Human ASM cells were transfected with RNF145 shRNA or treated with the E3 ligase inhibitor SMER3, followed by stimulation with fetal bovine serum (FBS) or platelet-derived growth factor (PDGF). RNF145 knockdown or SMER3 treatment dose-dependently inhibited mitogen-induced ASM …

Grieving And Attentiveness: Perception As Flourishing In Ocean Vuong And Mary Oliver, Madison Smith

Supporting Graduate Student Flourishing: Development Of A Whole-Person Formation Framework Through A University-Wide Task Force, Elisa Greene, Amanda Grieme-Bradley, Maren Bishop

Papers

How do whole persons form for lives of character and flourishing within graduate schooling years? What steps could an institution take to move toward that end? This work describes the process of one institution’s use of a task force examining these questions using a combination of literature review and structured interviews with key stakeholders across campus. The context of the institution’s unique mission, vision, and virtue framework provided a foundation out of which four areas of focus emerged: 1) infrastructure and representation, 2) belonging and community, 3) communication, and 4) professional identity formation. Investment in these institutional themes supports formation …

Demonstrating Superresolution In Radar Range Estimation Using A Denoising Autoencoder, Robert Czupryniak, Abhishek Chakraborty, Andrew N. Jordan, John C. Howell

Mathematics, Physics, and Computer Science Faculty Articles and Research

We apply machine learning methods to demonstrate radar range superresolution using a denoising autoencoder trained without supervision. Focusing on the estimation of a single physical parameter, the separation between two scatterers in the subwavelength regime, we constrain the network to a one-dimensional bottleneck layer with its size matched to the parameter dimensionality. We find that the bottleneck layer forms a reproducible, monotonic mapping with the true separation, showing that the network learns a low-dimensional representation directly aligned with the underlying physical parameter. We further show that this representation preserves the Fisher information of the signal, indicating that the network recovers …

A Distinct Form Of Fat Fibrosis Is Linked To Insulin Resistance In People With Hiv, Diana L Alba, Alaa Abdellatif, Moon Kyung Choi, Stephen M Brown Mayfield, Thuy An T Pham, David I Berrios, Antonio E Rodriguez, Marin Ewing, Tony R Figueroa, Judy Gonzalez-Vargas, Ningyan Zhang, Zhiqiang An, Dawei Bu, Steven G Deeks, Philipp E Scherer, Peter W Hunt, Suneil K Koliwad

The Brown Foundation: Institute of Molecular Medicine

BACKGROUND

Despite antiretroviral therapy (ART), people with HIV (PWH) are at heightened risk for insulin resistance (IR) and type 2 diabetes (T2D). Subcutaneous adipose tissue (SAT) fibrosis contributes to metabolic disease, but its role in IR among PWH is unknown. We investigated the relationship between SAT fibrosis and IR in PWH, along with transcriptional signatures to distinguish it from SAT fibrosis due to obesity.

METHODS

We analyzed body composition and SAT fibrosis (hydroxyproline) in 46 PWH and 74 people without HIV (PWoH), excluding individuals with T2D. We examined fibrosis-related gene transcription in the SAT using a targeted panel and measured …

The Employment Situation Of Veterans: July 2026, Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

The July 2026 Employment Situation of Veterans report indicates that veteran unemployment increased slightly from 4.1% in June to 4.2% in July, while post-9/11 veteran unemployment improved marginally from 4.8% to 4.7%. Although overall veteran employment conditions remained relatively stable, notable differences emerged across demographic groups. Younger veterans (ages 18–24) experienced a significant decline in unemployment, while rates increased among veterans ages 45–54. Female veteran unemployment rose slightly but remained below that of nonveteran women. Sharp increases were reported among Black and Hispanic veterans, highlighting persistent disparities. Overall, the report reflects a generally resilient veteran labor market amid broader economic …

Reluctant Revolutionaries: Andor, Fallout, And Narrating The Shifting Moral Economy Of Armed Politics In The United States, Cheng Xu

Government: Faculty Publications

This contribution to the special issue of the Forum argues that mainstream science fiction can be an important site for narrating a nascent change in the moral economy of armed politics in the United States. While firearm politics remain durably partisan, I show that a narrower but significant norm change is emerging: the boundary between ordinary gun ownership and politically charged preparedness has become more permeable, even as overt political violence remains broadly stigmatized. I develop this argument through an interpretive comparative reading of Disney’s Andor and Amazon’s Fallout as widely circulating cultural texts that register changing understandings of legitimacy, …

All Decisions

In this illegal lockout proceeding, Petitioner's prior OSC had been dismissed when courts closed for a snowstorm. The court vacated the dismissal, finding the snowstorm a reasonable excuse, and denied Respondent's cross-motion to dismiss, holding that Petitioner's name on the lease, billing statements, and the landlord's prior 90-Day Notice established his occupancy, and that failure to join his father as a necessary party did not require dismissal.

Garcia V. Miller

All Decisions

In this proceeding that converted from a holdover to a nonpayment proceeding and settled by stipulation requiring Petitioner to offer Respondent a rent-stabilized lease at $2,145/month, Respondent moved to compel compliance with the stipulation. The court granted Respondent's motion, ordering Petitioner to provide the agreed rent-stabilized lease and comply with outstanding repair obligations.

West 147th Street Equities, Llc V. Castillo

All Decisions

In this holdover proceeding premised on non-renewal of Respondent's deregulated tenancy for repeated non-payment under the Good Cause Eviction Law, Respondent moved to consolidate with a related nonpayment proceeding and to conduct discovery on the apartment's rent regulatory status. The court granted discovery but denied consolidation, finding the apartments involved different regulatory statuses and that a DHCR rent history showing a large unexplained rent increase warranted discovery into potential improper deregulation.
