Subterranean termites live in underground colonies with a division of labor among castes (i.e., queens and kings, workers, and soldiers). The function of social colonies relies on sophisticated chemical communication. Olfaction, the sense of smell from food, pathogens, and colony members, plays an important role in their social life. Olfactory plasticity in insects can be induced by long- and short-term environmental perturbations, allowing adaptive responses to the chemical environment according to their physiological and behavioral state. However, there is a paucity of information on the molecular basis of olfaction in termites. In this study, we identified an ortholog encoding the …

A Nondestructive Method Of Calculating The Wing Area Of Insects, Kexin Yu, Gadi V.P. Reddy, Julian Schrader, Xuchen Guo, Yirong Li, Yabing Jiao, Peijian Shi
Faculty Publications
Most insects engage in winged flight. Wing loading, that is, the ratio of body mass to total wing area, has been demonstrated to reflect flight maneuverability. High maneuverability is an important survival trait, allowing insects to escape natural enemies and to compete for mates. In some ecological field experiments, there is a need to calculate the wing area of insects without killing them. However, fast, nondestructive estimation of wing area for insects is not available based on past work. The Montgomery equation (ME), which assumes a proportional relationship between leaf area and the product of leaf length and width, is …

The corn earworm/bollworm, Helicoverpa zea (Boddie), is a pest species that is targeted by both Bacillus thuringiensis (Bt) maize and cotton in the United States. Cry1Ab and Vip3Aa20 are two common Bt toxins that are expressed in transgenic maize. The objective of this study was to determine the resistance allele frequency (RAF) to Cry1Ab and Vip3Aa20 in H. zea populations that were collected during 2018 and 2019 from four southeastern U.S. states: Louisiana, Mississippi, Georgia, and South Carolina. By using a group-mating approach, 104 F2 iso-lines of H. zea were established from field collections with most iso-lines (85) from Louisiana. …

In streams, unionoid mussels and fish form aggregations that exert bottom-up and top-down effects on food webs, but the magnitude and spatial extent of their effects are controlled by species traits. Sedentary mussels live burrowed in the sediment in patchily distributed dense aggregations (mussel beds) where they filter seston and provide a local, relatively constant nutrient subsidy. In contrast, fish move on and off mussel beds, and thus comprise a transient nutrient subsidy. We asked how overlap between fish and mussels influences nutrient recycling and resource distribution in streams. We conducted an 8-week study in experimental streams where we created …

Beyond Appetite Regulation: Targeting Energy Expenditure, Fat Oxidation, And Lean Mass Preservation For Sustainable Weight Loss, Berit Østergaard Christoffersen, Guillermo Sanchez-Delgado, Linu Mary John, Donna H. Ryan, Kirsten Raun, Eric Ravussin
Clinical Research Faculty Publications
New appetite-regulating antiobesity treatments such as semaglutide and agents under investigation such as tirzepatide show promise in achieving weight loss of 15% or more. Energy expenditure, fat oxidation, and lean mass preservation are important determinants of weight loss and weight-loss maintenance beyond appetite regulation. This review discusses prior failures in clinical development of weight-loss drugs targeting energy expenditure and explores novel strategies for targeting energy expenditure: mitochondrial proton leak, uncoupling, dynamics, and biogenesis; futile calcium and substrate cycling; leptin for weight maintenance; increased sympathetic nervous system activity; and browning of white fat. Relevant targets for preserving lean mass are also …

The Separator for Capture Reactions (SECAR) is a next-generation recoil separator system at the Facility for Rare Isotope Beams (FRIB) designed for the direct measurement of capture reactions on unstable nuclei in inverse kinematics. To maximize the performance of this system, stringent requirements on the beam alignment to the central beam axis and on the ion-optical settings need to be achieved. These can be difficult to attain through manual tuning by human operators without potentially leaving the system in a suboptimal and irreproducible state. In this work, we present the first development of online Bayesian optimization with a Gaussian process …

Faculty Publications
Additively manufactured Inconel 718 parts fabricated in three build orientations (horizontal, vertical, and angled at 45 degrees) are tested in fully-reversed bending fatigue mode. Damping measurements via the Impulse Excitation technique are used to assess the defects content in the microstructure and fractography analysis is performed to detect the root cause of failure. Two micro- and macro-scale methodologies of fatigue damage estimation based on the dissipated heat per cycle and the statistical estimation of micro-plastic strain energies are used to assess fatigue damage. It is shown that at a given stress level, the vertically built specimens endure the most fatigue …

Constraints On Dark Photon Dark Matter Using Data From Ligo's And Virgo's Third Observing Run, R. Abbott
Constraints On Dark Photon Dark Matter Using Data From Ligo's And Virgo's Third Observing Run, R. Abbott
Faculty Publications
We present a search for dark photon dark matter that could couple to gravitational-wave interferometers using data from Advanced LIGO and Virgo's third observing run. To perform this analysis, we use two methods, one based on cross-correlation of the strain channels in the two nearly aligned LIGO detectors, and one that looks for excess power in the strain channels of the LIGO and Virgo detectors. The excess power method optimizes the Fourier transform coherence time as a function of frequency, to account for the expected signal width due to Doppler modulations. We do not find any evidence of dark photon …

Are Long-Period Exoplants Around Cool Stars More Common Than We Thought?, Emily Jane Safron
LSU Doctoral Dissertations
The Kepler mission has been the catalyst for discovery of nearly 5,000 confirmed and candidate exoplanets. The majority of these candidates orbit Sun-like stars, and have orbital periods comparable to or shorter than that of the Earth, due to the selection bias inherent in the transit method and the limitations of automated transit search algorithms. We aim to develop a richer understanding of the population of exoplanets around the lowest-mass stars, the M spectral type. We are particularly interested in exoplanets with long orbital periods, which are difficult or impossible to find using standard transit search algorithms. In our study, …

Bipse: A Biomarker-Based Phase I/Ii Design For Immunotherapy Trials With Progression-Free Survival Endpoint, Beibei Guo, Yong Zang
Faculty Publications
A Bayesian biomarker-based phase I/II design (BIPSE) is presented for immunotherapy trials with a progression-free survival (PFS) endpoint. The objective is to identify the subgroup-specific optimal dose, defined as the dose with the best risk-benefit tradeoff in each biomarker subgroup. We jointly model the immune response, toxicity outcome, and PFS with information borrowing across subgroups. A plateau model is used to describe the marginal distribution of the immune response. Conditional on the immune response, we model toxicity using probit regression and model PFS using the mixture cure rate model. During the trial, based on the accumulating data, we continuously update …

Pharmakon In The Firelands: Connecting Historical Discourses And Small-Town Social Contexts With Substance Use Experience, Andrew Robert Burns
LSU Doctoral Dissertations
The ongoing increase in opioid and polysubstance-related overdoses and mortality in United States coincides with a shift in the ways substance use is understood. Once almost exclusively treated as a criminal problem, substance use, and overdose is increasingly viewed in terms of public health and from an urban to rural issue. The discourse surrounding the use of psychoactive substances largely omits the voices of the very people who use them. Likewise, the social context of small towns, at once not quite rural nor entirely urban, is generally given little consideration. To address these gaps in the research, I conduct two …
Essays On Intersection Of Economics And Judicial Decision-Making, Masoud Asadi
Essays On Intersection Of Economics And Judicial Decision-Making, Masoud Asadi
LSU Doctoral Dissertations
This dissertation consists of two chapters on the economics of judicial decision-making. In chapter 2, using the data from U.S. immigration courts and the Global Terrorism Dataset, I investigate the effect of terrorist attacks on asylum decisions. I find that terrorist attacks within the courts' states reduce the likelihood of granting asylums by 1.9 percent. This effect is driven by Islamic, Right-wing, and Lone-wolf terrorist attacks, and the magnitude of the effect is largest in the case of Islamic terrorist attacks (3.6 %) and smallest in the case of Lone-wolf attacks (1.9 %). Left-wing terrorist attacks have no impact on …

Synthesis Of Thiol-Acrylate Hydrogels For 3d Cell Culture And Microfluidic Applications, Anowar Hossain Khan
LSU Doctoral Dissertations
Globally cell culture is an $18.98 billion industry as of 2020, with an 11.6 percent annual growth rate. Drug discovery has an estimated worth of $69.8 billion in 2020 and is predicted to grow to $110.4 billion by 2025. Three-dimensional (3D) cell culture of cancer cells is one of the rapidly growing felids since it better recapitulates in vivo conditions compared to two-dimensional (2D) models. However, it is challenging to grow 3D tumor spheroids outside the body, and some of the existing technology can generate these spheroids outside the human body but poorly mimic in vivo tumor models. Therefore, there …
