Generalizing Parametrization Invariance In The Calculus Of Variations, Sanjay Dharmavaram, Basant Lal Sharma

Faculty Journal Articles

We revisit the notion of parametrization invariance while introducing certain weakened notions of invariance in the calculus of variations. In this work, we employ a straightforward approach in the classical setting and mostly restrict attention to functionals on one-dimensional domains. We establish a connection between parametrization invariant functionals and functionals embodying a weaker notion of invariance of their Lagrangian; we term this notion as T -Lagrangian analogous to the wellknown idea of null Lagrangian. However, the Euler-Lagrange operator of a T -Lagrangian vanishes only along the tangential direction in the configuration space. On one-dimensional domain and for first- and second-order …

Effectiveness Of A Postpartum Breastfeeding Protocol For Avoiding Pregnancy, Mary Schneider, Richard J. Fehring, Thomas Bouchard

College of Nursing Faculty Research and Publications

The uses of cervical mucus and basal body temperature as indicators of return to fertility postpartum have resulted in high unintended pregnancy rates. In 2013, a study found that when women used urine hormone signs in a postpartum/breastfeeding protocol this resulted in fewer pregnancies. To improve the original protocol's effectiveness, three revisions were made: (1) women were to increase the number of days tested with the Clearblue Fertility Monitor, (2) an optional second luteinizing hormone test could be done in the evening, and (3) instructions were given to manage the beginning of the fertile window for the first six cycles …

Scoping Review Of Early Toxic Stress And Epigenetic Alterations In The Neonatal Intensive Care Unit, Kathryn J. Malin, Kaboni W. Gondwe, Alissa V. Fial, Rachel Moore, Yvette P. Conley, Rosemary White-Traut, Thao Griffith

College of Nursing Faculty Research and Publications

Background

Preterm infants are uniquely vulnerable to early toxic stress exposure while in the neonatal intensive care unit (NICU) and also being at risk for suboptimal neurodevelopmental outcomes. However, the complex biological mechanisms responsible for variations in preterm infants’ neurodevelopmental outcomes because of early toxic stress exposure in the NICU remain unknown. Innovative preterm behavioral epigenetics research offers a possible mechanism and describes how early toxic stress exposure may lead to epigenetic alterations, potentially affecting short- and long-term outcomes.

Objective

The aim of this study was to review the relationships between early toxic stress exposures in the NICU and epigenetic …

The Texas Heart Institute Journal

BACKGROUND: Left ventricular diastolic dysfunction and nocturnal "nondipping" of blood pressure detected via ambulatory blood pressure monitoring are predictors of increased cardiovascular morbidity.

METHODS: A prospective cohort study including normotensive women with a history of preeclampsia in their current pregnancy was conducted. All cases were subjected to 24-hour ambulatory blood pressure monitoring and 2-dimensional transthoracic echocardiography 3 months after delivery.

RESULTS: This study included 128 women with a mean (SD) age of 28.6 (5.1) years and a mean (SD) basal blood pressure of 123.1 (6.4)/74.6 (5.9) mm Hg. Among the participants, 90 (70.3%) exhibited an ambulatory blood pressure monitoring profile …

Atrioventricular Nodal Ablation Is Not An Effective Treatment Strategy In Catecholaminergic Polymorphic Ventricular Tachycardia, S Yukiko Asaki, David Kessler, Aarushi Nayak, Jeffrey J Kim, Christina Y Miyake

The Texas Heart Institute Journal

Catecholaminergic polymorphic ventricular tachycardia is a rare but lethal heritable arrhythmia syndrome associated with both atrial and ventricular arrhythmias. Treatment includes antiarrhythmics, sympathetic denervation, and implantable cardioverter-defibrillators. The use of atrioventricular nodal ablation as a treatment strategy to prevent ventricular arrhythmias in catecholaminergic polymorphic ventricular tachycardia was not found in the literature. This report describes a teenager with a presenting rhythm of atrial and ventricular fibrillation and cardiac arrest. Her clinical arrhythmia was predominantly atrial dysrhythmias, which delayed her diagnosis of catecholaminergic polymorphic ventricular tachycardia. Before her diagnosis, she underwent atrioventricular nodal ablation in an effort to prevent ventricular arrhythmias, …

Assessment Of Meat Quality Attributes Of Four Commercial Broiler Strains Processed At Various Market Weights, A. J. Mueller, C. J. Maynard, A. R. Jackson, M. T. Kidd, S. J. Rochell, J. P. Caldas-Cueva, X. Sun, A. Giampietro-Ganeco, C. M. Owens

Poultry Science Faculty Publications and Presentations

As the demand for poultry meat continues to rise, industry production is constantly challenged with obtaining consumer needs. Integrators have answered this increasing demand by improving the growth rate of broilers allowing for increased production efficiently. The resulting broiler produces higher yields and a larger quantity of fresh poultry to satisfy consumer needs. However, this increase in efficiency has cost integrators as new quality issues continue to manifest through global production. Therefore, the objective of the current experiment was to evaluate the effect of genetic strain (standard and high yielding) and target weight on meat quality attributes such as pH, …

Grid Governance In The Energy-Trilemma Era: Remedying The Democracy Deficit, Daniel E. Walters, Andrew N. Kleit

Faculty Scholarship

Transforming the electric power grid is central to any viable scenario for addressing global climate change, but the process and politics of this transformation are complex. The desire to transform the grid creates an “energy trilemma” involving often conflicting desires for reliability, cost, and decarbonization; and, at least in the short run, it is difficult to avoid making tradeoffs between these different goals. It is somewhat shocking, then, that many crucial decisions about electric power service in the United States are made not by consumers or their utilities, nor by state public utilities commissions or federal regulators. Instead, for much …

(A)Woke Workplaces, Michael Z. Green

Faculty Scholarship

With heightened expectations for a reckoning in response to the broad support for the Black Lives Matter movement after the senseless murder of George Floyd in 2020, employers explored many options to improve racial understanding through discussions with workers. In rejecting any notions of the existence of structural or systemic discrimination, let alone the need to address the consequences of such discrimination, certain groups have begun to oppose BLM by seeking to diminish any social justice actions. One of those key resistance efforts includes labelling in pejorative terms any employers that pursue anti-racism objectives via social justice statements or internal …

Mass E-Carceration: Electronic Monitoring As A Bail Condition, Sara Zampierin

Faculty Scholarship

Over the past decade, the immigration and criminal legal systems have increasingly relied on electronic monitoring as a bail condition; hundreds of thousands of people live under this monitoring on any given day. Decisionmakers purport to impose these conditions to release more individuals from detention and to maintain control over individuals they perceive to pose some risk of flight or to public safety. But the data do not show that electronic monitoring successfully mitigates these risks or that it leads to fewer individuals in detention. Electronic monitoring also comes with severe restrictions on individual liberty and leads to harmful effects …

Immigration Law's Missing Presumption, Fatma Marouf

Faculty Scholarship

The presumption of innocence is a foundational concept in criminal law but is completely missing from quasi-criminal immigration proceedings. This Article explores the relevance of a presumption of innocence to removal proceedings, arguing that immigration law has been designed and interpreted in ways that disrupt formulating any such presumption to facilitate deportation. The Article examines the meaning of “innocence” in the immigration context, revealing how historically racialized perceptions of guilt eroded the notion of innocence early on and connecting the missing presumption to persistent associations between people of color and guilt. By analyzing how a presumption of innocence is impeded …

Cognitive Function Following Diabetic Ketoacidosis In Young Children With Type 1 Diabetes, Simona Ghetti, Kimberly S Quayle, Et Al.

2020-Current year OA Pubs

INTRODUCTION: Young children with type 1 diabetes (T1D) may be at particularly high risk of cognitive decline following diabetic ketoacidosis (DKA). However, studies of cognitive functioning in T1D typically examine school-age children. The goal of this study was to examine whether a single experience of DKA is associated with lower cognitive functioning in young children. We found that recently diagnosed 3- to 5-year-olds who experienced one DKA episode, regardless of its severity, exhibited lower IQ scores than those with no DKA exposure.

METHODS: We prospectively enrolled 46 3- to 5-year-old children, who presented with DKA at the onset of T1D, …

Symptomatic Benefit Of Momelotinib In Patients With Myelofibrosis: Results From The Simplify Phase Iii Studies, Ruben A Mesa, Stephen T Oh, Et Al.

2020-Current year OA Pubs

BACKGROUND: Myelofibrosis (MF)-associated constitutional symptoms can severely impact health-related quality of life. Clinical trials in MF traditionally measure symptom response to treatment as a landmark endpoint of total symptom score (TSS) reduction ≥50% from baseline. However, this dichotomous assessment provides a limited view of clinically relevant symptomatic changes. Herein we evaluated longitudinal change from baseline in TSS over the continuous 24-week period and individual symptom scores to obtain a more comprehensive understanding of symptom benefits experienced by patients with MF receiving therapy.

METHODS: Longitudinal symptom change was evaluated using mixed-effect model repeated measure (MMRM) methodology with individual item-level analyses to …
