Retained Placenta Removal Device (Womb-A), Savannah Fujimoto, Ciana Villar, Edward Barba

Biomedical Engineering

Womb-a aims to design a safe, minimally invasive, and effective product that solves the issue of removing retained placentas after childbirth reducing the risk of infection and uterine trauma. Womb-a brings a handheld motorized device that can be used at the bedside immediately after delivery of a baby. Retained placentas happen to approximately 1-3% of deliveries [1] which elevates the likelihood of postpartum infection and hemorrhaging. Current solutions include manual removal, windmill technique, and D&C which individually have severe issues such as elevating risk of infection, inconsistent removal of adhered placenta, and surgical complications. The Womb-a aims to mitigate these …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND AND AIM: Extracorporeal membrane oxygenation (ECMO) can help children survive severe cardiac and/or respiratory failure, but it is only provided in specialized centers. There are disparities in access by ground transport to ECMO services, but it is unknown to what extent interfacility transfer systems can expand access. Additionally, the number of children who live in proximity to centers that perform extracorporeal cardiopulmonary resuscitation (ECPR) to be potential candidates in case of out-of-hospital cardiac arrest (OHCA) is unknown. We conducted a geospatial analysis to answer these questions.

METHODS: We conducted a geospatial analysis of the Extracorporeal Life Support Organization (ELSO) …

Impact Of Cyp2d6 Genotype And Inhibitor Use On Risperidone Metabolism In Children: Functional Insights Into The *17 And *29 Alleles., Matthew H. Bennett, Ethan A. Poweleit, Samuel E. Vaughn, Brandon Retke, Paul C. Toren, Jeffrey R. Strawn, Laura Ramsey

Manuscripts, Articles, Book Chapters and Other Papers

Risperidone, an atypical antipsychotic, is increasingly prescribed in pediatric patients with psychiatric disorders. It is primarily metabolized by CYP2D6 to 9-hydroxyrisperidone, an active metabolite associated with a higher risk of adverse effects. The CYP2D6*17 and *29 alleles are prevalent in individuals of African ancestry and less studied than variants found in European ancestry individuals. This knowledge gap contributes to differences in health outcomes in individuals of non-European origin. The primary objective of this study is to replicate recently identified risperidone-specific activity for the CYP2D6*17 and *29 alleles. During psychiatric hospitalization, CYP2D6 was genotyped as part of routine care. Remnant plasma …

Stroke Increases Motor Output Variability During Maximal Voluntary Isometric Contractions Of Knee Extensor Muscles In Adults, Zhilun Zhou, Stephanie Christine Wolfe, Brian Schmit, Matthew J. Durand, Sandra Hunter, Allison Hyngstrom

Physical Therapy Faculty Research and Publications

Greater motor output variability (MOV, inconsistency and unsteadiness) during submaximal tasks post stroke is associated with poorer motor performance. However, little is known about MOV during maximal tasks and relationships with clinical measures of motor performance among stroke survivors. This study determined inconsistency (across discrete attempts) and unsteadiness (within a single attempt) during knee extension maximal voluntary isometric contractions (MVICs) in stroke survivors and neurotypical controls. Forty-three stroke survivors (28 female) and 31 age-matched neurotypical controls (15 female) performed a minimum of five knee extension MVICs with paretic and non-paretic legs (stroke) or dominant leg (controls). Inconsistency was calculated as …

Publications and Research

Context. An excess of soft X–ray emission (∼0.2 − 1 keV) above the contribution from the hot intracluster medium (ICM) has been detected in a number of galaxy clusters, including the Coma cluster. The physical origin of this emitting medium above the hot ICM has not yet been determined, in particular, it is unclear whether it is thermal or nonthermal.

Aims. We investigate the gas phase and gas structure that reproduce the soft excess radiation from the cluster core to the outskirts best using simulations.

Method. By using the IllustrisTNG simulation (TNG300), we predict the radial profile of thermodynamic properties …

Private Set Intersection: A Systematic Review, Yunbo Yang, Defan Zhu, Jianting Ning, Qi Feng, Xiaoguo Li, Yuejia Cheng, Guomin Yang, Kui Ren

Research Collection School Of Computing and Information Systems

Various services, such as search engines, are increasingly deployed in cloud-based and distributed systems. However, data are typically managed by trusted servers, making user privacy and data security critical concerns. Private set intersection (PSI) is a powerful cryptographic primitive that enables multiple parties to compute the intersection of their datasets without revealing private inputs. It has been extensively studied over the past two decades, leading to significant gains in computational and communication efficiency. Yet, in many real-world scenarios, revealing the raw intersection may still leak sensitive information. To address this, numerous PSI variants have been developed to meet different application …

Evaluating Carbon Risk And Benefit Under Improved Forest Management Prescriptions In A California Mixed Conifer Stand, Jonathan A. Garcia

Master's Theses

Improved forest management (IFM) prioritizes carbon accumulation through practices such as extended rotations and retention harvesting. These management strategies, increase fuel loads and elevate the potential fire intensity, may offset the benefits of carbon sequestration. Additionally, IFMs use spatially complex silvicultural treatments that may introduce prediction errors into the simulation processes used for long-term projections, and carbon accounting.

We evaluated the extent to which calibration in the Forest Vegetation Simulator (FVS) reduces error in aboveground carbon stock predictions and tested whether modeling approaches and calibration influence the magnitude and direction of basal area increment (BAI) prediction error using generalized mixed-effects …

The History Of Multi-Member Commissions At The Founding, 1789-1840: New Evidence On Independent Agencies, Victoria Frances Nourse

Georgetown Law Faculty Publications and Other Works

The executive removal power figures prominently on the Supreme Court’s current agenda. That agenda is beset, however, by a historical misunderstanding, when it comes to multi-member bodies, which too often are assumed to be modern creatures. This paper provides crucial new historical evidence showing that the Founders, indeed a who’s who list of Founders, approved and even sat on commissions in the Republic’s early years. In some cases, the Founders called these early commissions “independent,” deferred to their judgments as “final,” and demanded that the members be “impartial.” Given the vast discretion given these commissions, these characteristics are best described …

The Pro Bono Industrial Complex, Tanina Rostain

Georgetown Law Faculty Publications and Other Works

Recent settlements between corporate law firms and the Trump Administration, consisting of donations totaling nearly $1billion in free representation, have brought law firm pro bono to the fore. Pro bono has been institutionalized in corporate law firms since the turn of the 21^st century. Pro bono evangelists and corporate law firms contend that pro bono increases access to justice and protects individual rights. Scholarship on pro bono has not challenged these claims, focusing instead on managerial and organizational incentives that could increase the number of hours corporate firms devote to pro bono. Given the prominence of corporate law firm …

Feedback In Digital Game-Based Learning: A Taxonomy And The Design And Empirical Evaluation Of A Feedback System In A Mathematics Serious Game, André Almo

Dissertations

Digital Game-Based Learning (DGBL) is an active, student-centred pedagogical approach in which feedback plays a central role by informing learners’ actions, guiding decision-making and shaping motivation and engagement. Despite its importance, feedback in serious games is often described inconsistently and insufficiently in research, limiting comparability across studies and the accumulation of design knowledge, particularly for children. This thesis addresses these gaps through two complementary contributions: the development of a taxonomy for feedback design in digital serious games and the empirical evaluation of a taxonomy-informed feedback system in a mathematics game for primary school students. First, this work introduces the Taxonomy …

A Ghost Of Slavery: Osha’S De Facto Exclusion Of Incarcerated Workers, Jacqueline Glenn

The Business, Entrepreneurship & Tax Law Review

From chattel slavery to convict leasing to sharecropping to present-day prison work, exploitative labor has always had a place in the American economy. Incarcerated workers are compelled to perform long hours of dangerous work for mere pennies, often without adequate breaks and under the threat of solitary confinement, physical abuse, or other punitive measures if they refuse. Federal labor protections that shield free people from such conditions are largely unapplied to incarcerated workers, leaving them with little legal recourse. Tracing the development of involuntary labor through American history, this article contends that the Occupational Safety and Health Act of 1970 …

Sacbe 1 And Classic Maya Urban Culture, Traci Ardren, Scott R. Hutson, Travis W. Stanton, Patrick Rohrer, Justin P. Lowry

Anthropology Faculty Publications

One of the most significant engineering accomplishments of Maya civilization is Sacbe 1, a raised road connecting the ancient urban centers of Yaxuna and Coba. Using new lidar data in concert with excavation, epigraphic inscriptions, and landscape reconnaissance, we show that settlement and an urban experience emanated westward from Coba along the sacbe. The leaders of Coba - in particular, an ambitious seventh-century queen - used the sacbe to expand the political and cultural influence of their dynasty into the center of the peninsula while securing territory and resources. Gaps in the sacbe, precise delineation of its many curves, and …
