Towards Characterizing And Quantifying Interpretability Of Knowledge Graph Embedding Models, Narayanan Asuri Krishnan
Towards Characterizing And Quantifying Interpretability Of Knowledge Graph Embedding Models, Narayanan Asuri Krishnan
Theses
Knowledge graphs are structured representations of real-world information, where entities are connected by edges with labels known as predicates. These graphs contain logical patterns, known as inference patterns, such as symmetry, transitivity and composition, to name a few. To leverage the information contained within a knowledge graph, embedding methods have been developed to encode entities and predicates as numerical vectors in a multi-dimensional space. These embeddings aim to capture the semantic and structural information of the graph, including the inference patterns. However, the sub-symbolic nature of these embeddings present significant challenges in terms of interpretability. Additionally, each embedding model utilizes …

It examines a broad range of CRs encountered in diverse manufacturing methods, such as laser powder bed fusion (LPBF), directed energy deposition …
Custom’S Pervasive Role In Law And The Boundaries Of Positivism, James Paul George
Custom’S Pervasive Role In Law And The Boundaries Of Positivism, James Paul George
Faculty Scholarship
Custom is law’s foundation, modulator, and occasional antithesis. This Article explores that relationship, starting with varying insights from some of the few legal philosophers who have examined the custom/law dynamic. The heart of this Article provides examples showing custom’s many influences on the law, set in five functional areas: origin, application, interstitial, rule-source, and oppositional. Although the custom/law interplay spans human behavior, these examples come from law practice where custom is exposed. Many are routine, some are significant, and all show our reliance on behaviors and norms that are not positive law. The conclusion addresses but does not resolve some …
We Need To Talk: Modernizing Attorney-Client Jail Communications, Cynthia Alkon
We Need To Talk: Modernizing Attorney-Client Jail Communications, Cynthia Alkon
Faculty Scholarship
Attorney-client jail phone calls, video calls, and emails are all routinely recorded and monitored by jails, with numerous examples of jails and private telecommunications providers giving those recordings and emails to law enforcement and prosecutors. This widespread failure to protect the confidentiality of attorney-client communications prevents lawyers from being able to enjoy easy, quick, and regular communications with their clients. In practice, and despite the ever-expanding communication methods in the outside world, those held in jails in this country while their criminal cases are pending are effectively stuck in the nineteenth century when the only way to communicate was in …
Water Reallocation In The West: Government And Markets, Vanessa Casado Pérez
Water Reallocation In The West: Government And Markets, Vanessa Casado Pérez
Faculty Scholarship
Water is multifaceted: it is a human right, a production input, a sacred element, an investment asset, public property, and a fugitive resource. Its reallocation is inherently difficult because of its natural characteristics and its hybrid nature that combines public ownership with private rights. The future of the U.S. West necessitates the reallocation of water resources, even with potential new water supplies. As climate change intensifies, reallocation will take various forms—all involving government intervention to some degree, from eminent domain to competitive markets. For water markets to function effectively, they require robust institutional infrastructure to prevent issues like imperfect information …

Feedbacks Between Fjord Circulation, Mélange Melt, And The Subglacial Discharge Plume At Kangerlussuaq Glacier, East Greenland, M. Wood, I. Fenty, A. Khazendar, J. K. Willis
Faculty Research, Scholarly, and Creative Activity
In recent decades, the Greenland ice sheet has been losing ice and contributing substantially to global sea level rise. Approximately half of this recent loss is due to glacier acceleration, increasing the calving of icebergs into the ocean. This process has been linked with increased ocean heat content on the continental shelf, yet the pathways delivering this heat into Greenland's fjords and its interactions with fjord-scale processes modulating glacier ice loss are still unclear. In this study, we use a series of numerical ocean model configurations to examine feedbacks between ocean circulation, subglacial discharge, submarine glacier melt, and ice mélange …

MYCN-amplification is a genetic hallmark of ~40% of high-risk neuroblastomas (NBs). Altered glycosylation is a common feature of adult cancer progression, but little is known about how genetic signatures such as MYCN-amplification alter glycosylation profiles. Herein, matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) revealed increased core fucosylated glycan abundance within neuroblast-rich regions of human MYCN-amplified NB tumors. GDP-mannose 4,6-dehydratase (GMDS) is responsible for the first-committed and rate-limiting step of de novo GDP-fucose synthesis. High GMDS expression was found to be associated with poor patient survival, advanced stage disease, and MYCN-amplification in human NB tumors. Chromatin immunoprecipitation and promoter reporter assays …

The rising incidence of advanced-stage colorectal cancer (CRC) and poor survival outcomes necessitate new and effective therapies. Immune checkpoint inhibitors (ICIs), specifically anti-PD-1 therapy, show promise, yet clinical determinants of a positive response are suboptimal. Here, we identify microRNA-155 (miR-155) as necessary for CD8 + T cell-infiltrated tumors through an unbiased in vivo CRISPR-Cas9 screen identifying functional tumor antigen-specific CD8+ T cell-expressed microRNAs. T cell miR-155 is required for anti-PD-1 responses and for a vital intratumor CD8 + T cell differentiation cascade by repressing Ship-1, inhibiting Tcf-1 and stemness, and subsequently enhancing Cxcr6 expression, anti-tumor immunity, and effector functions. Based …
Staying Sane In The Membrane: Neutral Sphingomyelinase 2 As A Master Regulator Of Plasma Membrane Ceramide, Zainuddin Quadri, Erhard Bieberich
Staying Sane In The Membrane: Neutral Sphingomyelinase 2 As A Master Regulator Of Plasma Membrane Ceramide, Zainuddin Quadri, Erhard Bieberich
Markey Cancer Center Faculty Publications
Ceramide, a key signaling sphingolipid in the plasma membrane, plays a pivotal role in fundamental cellular processes such as adhesion, polarity, and programmed cell death. The generation of plasma membrane ceramide is largely attributed to the activity of two types of sphingomyelinases: neutral sphingomyelinase 2 (nSMase2, Smpd3) and acid sphingomyelinase (aSMase, Smpd1). While many studies have explored ceramide generation following experimental activation of these enzymes, the mechanisms governing basal or steady- state ceramide levels have remained poorly understood. Using an innovative mass spectrometry approach developed in the Canals’ lab, the team has quantified the distinct contributions of nSMase2 and aSMase …

Bilirubin Bioconversion To Urobilin In The Gut-Liver-Kidney Axis: A Biomarker For Insulin Resistance In The Cardiovascular-Kidney-Metabolic (Ckm) Syndrome, Zachary A. Kipp, Olufunto O. Badmus, David E. Stec, Brantley Hall, Terry D. Hinds Jr.
Markey Cancer Center Faculty Publications
The rising rates of obesity worldwide have increased the incidence of cardiovascular disease (CVD), making it the number one cause of death. Higher plasma bilirubin levels have been shown to prevent metabolic dysfunction and CVD. However, reducing levels leads to deleterious outcomes, possibly due to reduced bilirubin half-life that escalates the production of its catabolized product, urobilinogen, produced by gut bacteria and naturally oxidized to urobilin. Recent findings suggest that the involvement of the microbiome catabolism of bilirubin to urobilin and its absorption via the hepatic portal vein contributes to CVD, suggesting a liver-gut axis involvement. We discuss the studies …

Markey Cancer Center Faculty Publications
A challenge in viral vaccine development is to produce vaccines that generate both neutralizing antibodies to prevent infection and cytotoxic CD8+ T-cells that target conserved viral proteins and can eliminate infected cells to control virus spread. mRNA technology offers an opportunity to design vaccines based on conserved CD8-targeting epitopes, but achieving robust antigen-specific CD8+ T-cells remains a challenge. Here, we tested the viral-derived oligonucleotide DDO268 as an adjuvant in the context of a model influenza A virus (IAV) nucleoprotein (NP) mRNA vaccine in C57BL/6 mice. DDO268 when co-packaged with mRNA in lipid nanoparticles is sensed by RIG I-like receptors and …
The Mitochondria As An Emerging Target Of Self- Renewal In T-Cell Acute Lymphoblastic Leukemia, Majd Al-Hamaly, Evelyn Winter, Jessica S. Blackburn
The Mitochondria As An Emerging Target Of Self- Renewal In T-Cell Acute Lymphoblastic Leukemia, Majd Al-Hamaly, Evelyn Winter, Jessica S. Blackburn
Markey Cancer Center Faculty Publications
Acute lymphocytic leukemia (ALL) is the most common leukemia in children, with the T-cell subtype (T- ALL) accounting for 15% of those cases. Despite advancements in the treatment of T-ALL, patients still face a dismal prognosis following their first relapse. Relapse can be attributed to the inability of chemotherapy agents to eradicate leukemia stem cells (LSC), which possess self-renewal capabilities and are responsible for the long-term maintenance of the disease. Mitochondria have been recognized as a therapeutic vulnerability for cancer stem cells, including LSCs. Mitocans have shown promise in T-ALL both in vitro and in vivo, with some currently in …

Potential Mental Disorder Symptoms In The Prophet Elijah: An Exegetical And Psychological Analysis Of Selected Episodes From 1 Kings 18–19, Dariusz Iwański, Thomas G. Plante
Psychology
This interdisciplinary study examines the prophet Elijah’s experiences as depicted in 1 Kings 18–19 through a multidisciplinary lens, combining theological, literary, and psychological perspectives. Drawing on literary and historical–critical methods, a biblical scholar analyzes the narrative’s linguistic and cultural dimensions, while a psychologist evaluates these findings using contemporary mental health frameworks, including the DSM-5 and models of spiritual struggle. By synthesizing these approaches, the study explores Elijah’s emotional challenges, highlighting their resonance with modern understandings of mental health and spirituality. The findings suggest that Elijah’s profound struggles—marked by triumph, despair, and renewal—offer valuable insights into the interplay of faith, vulnerability, …

Kimmel Cancer Center Faculty Papers
The National Cancer Institute's (NCI) Cancer Center Support Grant mandates that NCI-designated cancer centers establish a Community Outreach and Engagement (COE) component to help direct efforts at reducing cancer burden within their catchment areas. Despite the critical role of COE offices, little is known about how they track and evaluate outreach activities and outcomes. We gathered information on current practices from representatives of 40 out of 65 COE offices using an online survey. Although nearly all responding centers (97.5%) tracked COE activities, no consensus existed on resources used, and satisfaction with current solutions was mixed (51.0% not satisfied). Respondents expressed …

Objectives: Approximately 80% of people with epilepsy live in low- and middle-income countries (LMICs), where limited resources and stigma hinder accurate diagnosis and treatment. Clinical machine learning models have demonstrated substantial promise in supporting the diagnostic process in LMICs by aiding in preliminary screening and detection of possible epilepsy cases without relying on specialised or trained personnel. How well these models generalise to naïve regions is, however, underexplored. Here, we use a novel approach to assess the suitability and applicability of such clinical tools to aid screening and diagnosis of active convulsive epilepsy in settings beyond their original training contexts. …

ABSTRACT Splanchnic artery aneurysms, particularly those involving the left gastric artery, are infrequent occurrences and often lack noticeable symptoms, but their rupture involves a significant risk of mortality. We present a case involving an unruptured left gastric artery aneurysm (LGAA) that extended into the right hemithorax. This case report outlines the categorization, clinical manifestations, and diagnostic challenges associated with such aneurysms. Our findings could offer valuable insights for clinicians and radiologists when adopting a systematic approach for the early detection and management of LGAA.
