Excitation of ionic solids with extreme ultraviolet pulses creates localized core-level excitons, which in some cases couple strongly to the lattice. Here, core-level-exciton states of magnesium oxide are studied in the time domain at the Mg L2,3 edge with attosecond transient reflectivity spectroscopy. Attosecond pulses trigger the excitation of these short-lived quasiparticles, whose decay is perturbed by time-delayed near-infrared pulses. Combined with a few-state theoretical model, this reveals that the infrared pulse shifts the energy of bright (dipole-allowed) core-level-exciton states as well as induces features arising from dark core-level excitons. We report coherence lifetimes for the two lowest core-level excitons …

Development Of A Surgical Procedure For Removal Of A Placentome From A Pregnant Ewe During Gestation, Colleen A. Lambo, Ashley K. Edwards, Fuller W. Bazer, Kathrin Dunlap, M. Carey Satterfield

Faculty Publications

Background: In recent decades, there has been a growing interest in the impact of insults during pregnancy on postnatal health and disease. It is known that changes in placental development can impact fetal growth and subsequent susceptibility to adult onset diseases; however, a method to collect sufficient placental tissues for both histological and gene expression analyses during gestation without compromising the pregnancy has not been described. The ewe is an established biomedical model for the study of fetal development. Due to its cotyledonary placental type, the sheep has potential for surgical removal of materno-fetal exchange tissues, i.e., placentomes. A novel …

Large volumes of temporal event data, such as online check-ins and electronic records of hospital admissions, are becoming increasingly available in a wide variety of applications including healthcare analytics, smart cities, and social network analysis. Those temporal events are often asynchronous, interdependent, and exhibiting self-exciting properties. For example, in the patient's diagnosis events, the elevated risk exists for a patient that has been recently at risk. Machine learning that leverages event sequence data can improve the prediction accuracy of future events and provide valuable services. For example, in e-commerce and network traffic diagnosis, the analysis of user activities can be …

Alternative Methods, Hunter Stabler

LSU Master's Theses

ABSTRACT

In the realm of precognitive artmaking, the artist’s role is that of an antenna. One must be receptive to the subtle, invisible flow of creative novelty in order to participate in the involuntary channeling of new ideas, new processes, and alternative methods of creative production. Carving out new territory within the realm of static art is a primary objective for my artistic process. By utilizing digital fabrication tools, paired with my affinity for intricate craft and optical metagrobolization, I have created a body of work that invents alternative processes and unique aesthetic languages.

© Copyright © 2020 Fu, Liu, Li, Li and Wang. Cardiac fibrosis is a common pathological change associated with cardiac injuries and diseases. Even though the accumulation of collagens and other extracellular matrix (ECM) proteins may have some protective effects in certain situations, prolonged fibrosis usually negatively affects cardiac function and often leads to deleterious consequences. While the development of cardiac fibrosis involves several cell types, the major source of ECM proteins is cardiac fibroblast. The high plasticity of cardiac fibroblasts enables them to quickly change their behaviors in response to injury and transition between several differentiation states. However, the …

Examining Relationships Between Early Childcare Teachers' Adult Attachment Orientations And Quality Of Interaction In The Infant Classroom, Alexandra Morris Benoit

LSU Doctoral Dissertations

Over the past several decades, women have entered the workforce in increasing numbers. This has led to the majority of infants and young children being cared for outside of the home by extra-familial caregivers. Research has shown the benefits that quality childcare can have on the developmental trajectories of children, as well as the detrimental effects that can be seen when children experience low quality care. Further, children are particularly vulnerable in the first year of life when they are establishing attachment bonds with their primary caregivers. With the long hours that many spend in the care of childcare workers, …

Promoter-Proximal Chromatin Domain Insulator Protein Beaf Mediates Local And Long-Range Communication With A Transcription Factor And Directly Activates A Housekeeping Promoter In Drosophila, Yuankai Dong, S. V. Satya Prakash Avva, Mukesh Maharjan, Janice Jacobi, Craig M. Hart

Faculty Publications

Copyright © 2020 by the Genetics Society of America BEAF (Boundary Element-Associated Factor) was originally identified as a Drosophila melanogaster chromatin domain insulator-binding protein, suggesting a role in gene regulation through chromatin organization and dynamics. Genome-wide mapping found that BEAF usually binds near transcription start sites, often of housekeeping genes, suggesting a role in promoter function. This would be a nontraditional role for an insulator-binding protein. To gain insight into molecular mechanisms of BEAF function, we identified interacting proteins using yeast two-hybrid assays. Here, we focus on the transcription factor Serendipity d (Sry-d). Interactions were confirmed in pull-down experiments using …
