Biological and Agricultural Engineering Faculty Publications and Presentations

Efficiently managing agricultural systems necessitates accurate data collection from crops to examine phenotypic characteristics and improve productivity. Traditional data collection processes for specialty horticultural crops are often subjective, labor-intensive, and may not provide accurate information for precise management decisions in phenotypic studies and crop production. Reliable and standardized techniques to record and evaluate crop features using agricultural technology are essential for improving agricultural systems. The objective of the research was to develop a methodology for accurate measurement of blackberry flowers and vegetation coverage using UAV remote sensing and image analysis. The UAV captured 20,812 images in the visible spectrum, and …

Structural Projections To The Nucleus Accumbens Link To Impulsive Components Of Human Risk Preference, Loreen Tisdall, Kelly H. Macniven, Josiah Leong, Renato Frey, Jörg Rieskamp, Ralph Hertwig, Brian Knutson, Rui Mata

Psychological Science Faculty Publications and Presentations

Functional responses in the Nucleus Accumbens (NAcc) to risk- and reward-related cues can predict real-life risk-taking behavior. Since NAcc activity depends on neurotransmission from connected brain regions, projections to the NAcc may also predict risk preference. To quantify risk preference, we employed latent variables previously derived in a comprehensive, independent study examining the psychometric structure of risk preference, which yielded a general risk preference factor as well as several specific factors, including a factor capturing impulsivity. Informed by previous work, we preregistered a set of hypotheses concerning the association between different risk preference factors and fractional anisotropy (or FA, which …

Gains In Soil Carbon Storage Under Anthropogenic Nitrogen Deposition Are Rapidly Lost Following Its Cessation, Brooke E. Propson, Donald R. Zak, Aimée T. Classen, Andrew J Burton, Zachary B. Freedman

Michigan Tech Publications

In the Northern Hemisphere, anthropogenic nitrogen (N) deposition contributed to the enhancement of the global terrestrial carbon (C) sink, partially offsetting CO2 emissions. Across several long-term field experiments, this ecosystem-level response was determined to be driven, in part, by the suppression of microbial activity associated with the breakdown of soil organic matter. However, since the implementation of emission abatement policies in the 1970s, atmospheric N deposition has declined globally, and the consequences of this decline are unknown. Here, we assessed the response of soil C storage and associated microbial activities, in a long-term field study that experimentally increased N deposition …

Diverse Pathways In Gpcr-Mediated Activation Of Ca2+ Mobilization In Hek293 Cells, Francesco De Pascali, Asuka Inoue, Jeffrey L. Benovic

Department of Biochemistry and Molecular Biology Faculty Papers

G protein-coupled receptors transduce extracellular stimuli into intracellular signaling. Ca²⁺ is a well-known second messenger that can be induced by G protein-coupled receptor activation through the primary canonical pathways involving Gα_q- and Gβγ-mediated activation of phospholipase C-β (PLCβ). While some G_s-coupled receptors are shown to trigger Ca²⁺ mobilization, underlying mechanisms remain elusive. Here, we evaluated whether G_s-coupled receptors including the β₂-adrenergic receptor (β₂AR) and the prostaglandin EP₂ and EP₄ receptors (EP₂R and EP₄R) that are endogenously expressed in human embryonic kidney 293 …

Engineering The Coherent Phonon Transport In Polar Ferromagnetic Oxide Superlattices, In Hyeok Choi, Seung Gyo Jeong, Do-Gyeom Jeong, Ambrose Seo, Woo Seok Choi, Jong Seok Lee

Chemical and Materials Engineering Faculty Publications

Artificial superlattices composed of perovskite oxides serves as an essential platform for engineering coherent phonon transport by redefining the lattice periodicity, which strongly influences the lattice-coupled phase transitions in charge and spin degrees of freedom. However, previous methods of manipulating phonons have been limited to controlling the periodicity of superlattice, rather than utilizing complex mutual interactions that are prominent in transition metal oxides. In this study on oxide superlattices composed of ferromagnetic metallic SrRuO3 and quantum paraelectric SrTiO3 , phonon modulation by controlling the geometry of superlattice in atomic-scale precision is realized, demonstrating the coherent phonon engineering using structural and …

Chronologically Inappropriate Morphogenesis (Chinmo) Is Required For Maintenance Of Larval Stages Of Fall Armyworm, Xien Chen, Jinmo Koo, Surjeet Kumar Arya, Subba R. Palli

Entomology Faculty Publications

Broad complex (Br-C) and eip93F (E93) transcription factors promote insect metamorphosis from larva to pupa and from pupa to adult, respectively. Recently, chronologically inappropriate morphogenesis (Chinmo) has been proposed as a larval specifier in Drosophila melanogaster. However, whether Chinmo is required for larval maintenance in lepidopteran insects, the underlying mechanisms involved in maintaining the larval stage, and its interactions with the JH signaling pathway are not well understood. Here, we used a binary transgenic CRISPR/Cas9 system to knockout Chinmo and Kr-h1 (primary response gene in the JH signaling pathway) in the fall armyworm (FAW). Kr-h1 knockout induced premature metamorphosis only …

Repeated Shifts In Sociality Are Associated With Fine-Tuning Of Highly Conserved And Lineage-Specific Enhancers In A Socially Flexible Bee, Beryl M. Jones, Andrew E. Webb, Scott M. Geib, Sheina Sim, Rena M. Schweizer, Michael G. Branstetter, Jay D. Evans, Sarah D. Kocher

Entomology Faculty Publications

Comparative genomic studies of social insects suggest that changes in gene regulation are associated with evolutionary transitions in social behavior, but the activity of predicted regulatory regions has not been tested empirically. We used self-transcribing active regulatory region sequencing, a high-throughput enhancer discovery tool, to identify and measure the activity of enhancers in the socially variable sweat bee, Lasioglossum albipes. We identified over 36,000 enhancers in the L. albipes genome from 3 social and 3 solitary populations. Many enhancers were identified in only a subset of L. albipes populations, revealing rapid divergence in regulatory regions within this species. Population-specific enhancers …

Avulsion Of The Flexor Digitorum Profundus Tendon During The Curettage Of A Recurrent Enchondroma: A Case Report, Shunpei Hama, Masataka Yasuda, Makoto Fukuda, Katsuaki Onishi, Takaaki Chikugo

Children’s Nutrition Research Center Staff Publications

Enchondroma rarely occurs in the distal phalanx, and avulsion of the flexor digitorum profundus (FDP) tendon in this area is also rare. We report a case of recurrent enchondroma in the distal phalanx, which required reconstruction for an accidental FDP avulsion during surgery. A 36-year-old right-handed woman visited our hospital with a suspected recurrence of enchondroma and a planned surgery. Radiographs and computed tomography revealed three translucent lesions in the distal phalanx of her left index finger. We performed curettage and calcium phosphate bone cement (CPC) grafting. During the procedure, an avulsion of the FDP tendon was found. We reattached …

What Drives Gut Microbial Diversity And Community Structure Among Closely-Related Host Species?, Rylee Jensen

All NMU Master's Theses

The gut microbiome (GMB) of mammals hosts an important community of microbes that perform countless micro-ecosystem services for the host and are influenced by numerous factors including host physiology, environment, and phylogeny. Phylogeny may have a unique effect on GMB diversity and community structure (i.e., a GMB profile) via phylosymbiosis, a theory in which the evolution of hosts matches the evolution of their associated microbiota. Elucidating phylosymbiosis in mammals is difficult because multiple intrinsic and extrinsic factors collectively drive individual GMB variation. Thus, there is a need to simultaneously analyze the role of physiology, environment, and phylogeny on shaping host …

Determining The Impact Of Lethal Temperature And Relative Humidity When Combined With Various Insecticide Classes Against A Bed Bug (Cimex Lectularius) Population., Bandana Shrestha

LSU Master's Theses

Common bed bugs (Cimex lectularius) are obligatory blood-feeding pests that have adapted well to survive in challenging environmental conditions. Known for their high tolerance to dehydration, low water loss, and high critical thermal maximum, they have become difficult to manage. Environmental factors, particularly temperature and humidity, play a significant role in their survival. However, with growing resistance to insecticides, integrated pest management (IPM) strategies are now essential for effective bed bug control. A key strategy in IPM involves combining insecticides with heat treatments. This method aims to overcome the limitations of heat treatment alone, as bed bugs may …

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.

Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.
