Dramatic Biases In Terrestrial Nitrogen Fixation In Earth System Models Revealed By Natural Isotope Signatures, Maoyuan Fang, Shushi Peng, Philippe Ciais, Daniel S. Goll, Benjamin Z. Houlton, Ying-Ping Wang, Yilong Wang, Pan Liu, Joshua B. Fisher, Pierre Regnier

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Biological nitrogen fixation (BNF) is the primary input of new reactive nitrogen to natural terrestrial ecosystems. However, this flux is poorly constrained due to its unclear drivers and associated control mechanisms. Here, we extend the existing theory of nitrogen (N) isotope mass balance to estimate BNF rates and then use a Bayesian approach to constrain the BNF rates in natural terrestrial ecosystems by using measurements of natural N-isotope ratios (δ¹⁵N) in plants (δ_P) and soil (δ_S). Together with pairwise δ_P and δ_S measurements from 18 forest sites covering diverse climates and thousands …

A New Scheme For Simple Asymmetric Bivariate Copulas And Applications, Rachid Bentoumi, Farid El Ktaibi, Christophe Chesneau

All Works

Bivariate copulas play a central role in modeling the dependence structure between two random variables and serve as a fundamental tool in various applied fields. In this article, we develop a new theoretical framework aimed at constructing simple asymmetric bivariate copulas of the form C(u, v) = uv [ϕ(v) + u(1 − ϕ(v))^], (u, v) ∈ [0, 1]². This framework relies on a tuning univariate function to achieve the desired asymmetry. We study this pioneering scheme, emphasizing its theoretical foundations, and illustrating it with several examples. More precisely, we establish important properties of the proposed copulas …

Meta Transfer Learning For Brain Tumor Segmentation Using Nnunet In Meningioma And Metastasis Cases, Mehnaz Tabassum, Antonio Di Ieva, Sidong Liu

Staff Scholarship - Australia & Dubai

In recent years, numerous algorithms have emerged for the segmentation of brain tumors, driven by advancements in deep learning techniques, where the objective is to identify and delineate various tumor sub-regions. While deep learning models like nnUNet have shown promising results in glioma segmentation, their effectiveness in segmenting other brain tumor subtypes, such as meningiomas and metastases, remains uncertain, especially when the available dataset lacks representative examples. To address this challenge, we propose a meta-transfer learning approach, which involves fine-tuning the nnUNet model on datasets containing meningiomas and metastases while leveraging the knowledge acquired from glioma segmentation. This approach aims …

Modeling Nutrient Functions: Strengthening The Reliability And Applicability Of Ecosystem Service Models For Land Use Decision-Making, Mariam Gabriela Valladares Castellanos

LSU Doctoral Dissertations

Effective water quality management requires a clear understanding of both the magnitude and spatial distribution of nutrient retention and export across dynamic landscapes, given their direct implications for drinking water supply, ecosystem integrity, fisheries, and recreational uses. Equally important is anticipating trade-offs from management actions, which can alter ecosystem functioning and the flow of services. Modeling tools provide a means to predict nutrient outcomes, evaluate these trade-offs, and support decision-making; however, their utility is often constrained by persistent challenges, including model uncertainty, limited applicability in data-scarce regions, and insufficient empirical foundations to inform scenario-driven decision-making. This dissertation addresses these gaps …

Impact Of Transplant Conditioning, Npm1 Mutations, And Measurable Residual Disease In Flt3-Itd Acute Myeloid Leukemia, Mark J Levis, Geoffrey L Uy, Et Al.

2020-Current year OA Pubs

We conducted a post hoc analysis of data from Blood and Marrow Transplant Clinical Trials Network 1506 (MORPHO), a randomized trial of gilteritinib vs placebo as posttransplantation maintenance for patients with FLT3-ITD-mutated acute myeloid leukemia (AML) undergoing allogeneic hematopoietic cell transplantation (HCT), focusing the interactions between conditioning regimen intensity, measurable residual disease (MRD), and NPM1 comutation status reported from diagnosis. Comparing FLT3-ITD MRD before and after conditioning, there was no difference between myeloablative conditioning (MAC) and reduced-intensity conditioning (RIC) in eradication or reduction of FLT3-ITD MRD. For participants who were FLT3-ITD MRD negative before HCT, there was no difference in …

Faculty, Staff and Student Publications

Background/Objectives: Gene rearrangements involving oncogenes are major drivers in acute leukemia, influencing disease classification, prognosis, and therapeutic decision-making. Targeted RNA sequencing (RNA-Seq) panels capable of detecting intergenic and intragenic fusions across multiple genes are increasingly used in diagnostic settings. However, comparative evaluation with orthogonal technologies remains limited.

Material and Methods: We compared the performance of a 108-gene anchored multiplex PCR (AMP)-based RNA-Seq panel with that of Optical Genome Mapping (OGM) in 467 acute leukemia cases. The cohort included 360 cases of acute myeloid leukemia (AML), 89 B-lymphoblastic leukemia (B-ALL), 12 T-lymphoblastic leukemia (T-ALL), and 6 cases of mixed phenotype …

School of Geography, Earth and Environmental Sciences

Coastal boulder deposits provide vital information on extreme wave events. They are crucial for understanding storm and tsunami impacts on rocky coasts, and for understanding long-term hazard histories. But study of these deposits is still a young field, and growth in investigation has been rapid, without much contactbetween research groups. Therefore, inconsistencies in field data collection among different studies hinder crosssite comparisons and limit the applicability of findings across disciplines. This paper analyses field methodologiesfor coastal boulder deposit measurement based using an integrated database (ISROC-DB), and demonstrates inconsistencies in current approaches. We use the analysis as a basis for outlining …

Formation And Dramatic Significance Of The “Separation” System In Ming Dynasty Southern Opera Scripts, Zhiyong Chen

Theoretical Studies in Literature and Art

The practice of “fenchu” (separation) marks a pivotal development in the Ming dynasty's chuanqi playwriting system, manifesting as either “implicit” or “explicit” separation within early Southern Opera texts. The late Ming period saw enhancements in the separation methodologies within actors' performance manuscripts and reader-oriented printed editions, improving upon the character entry and exit strategies from the Song, Yuan, and early Ming operas. This led to the formulation of separation standards that reconcile character transitions, scene consistency, and narrative cohesion. The emergence of the separation mechanism in Southern Opera is attributed to multifaceted causes: for performance scripts, it facilitated …

The Movement For The Popularization Of Literature And Art: Development And Transformation, Yanqiu Zhao

Theoretical Studies in Literature and Art

The major issues and fundamental perspectives concerning the popularization of literature and art can be broadly categorized into six aspects: the direction of development, the object of service, the subject of creation, the content and form, the language, and the evaluation of the May Fourth and New Culture Movements. While the theory and practice of the popularizing literature and art hold positive significance, they are also subject to biases and limitations. Mao Zedong, rather than merely perpetuating the ideals and objectives of the movement, deconstructed, synthesized and reformed its content and issues. He proposed his own insights and solutions to …

The Use Of Firgun To Improve Burnout And Workplace Civility In A Pediatric Cancer Center, Karen Moody, Jerry Stein, Deena Levine, Arshia Madni, Clark R. Andersen, Amy Heaton, Alakh P. Rajan, Demetrios Petropoulos, Jian Wang, Deborah Kramer

Advances in Cancer Education and Quality Improvement

Burnout afflicts 35% to 44% of pediatric oncology physicians, nurses, and interprofessional staff and is related to excessive workloads and emotional exhaustion. Conversely, a healthy work environment is a protective factor for burnout among physicians and nurses. Meaningful recognition is a published standard necessary for creating a healthy work environment. This study aimed to reduce staff burnout through firgun, defined as a heartfelt way to express accomplishments of another person. Pediatric oncology staff completed a firgun educational module and logged acts of firgun during a 3-month study period. Validated measures assessing burnout, workplace civility, well-being, work-life balance, and perceived …
