Show moreRed sunflower seed weevil (RSSW) is a major insect pest of cultivated and wild common sunflowers in the Great Plains of North America. The extent of the sunflower damage due to RSSW infestation is too great for the natural sunflower defense mechanisms to protect the agriculture industry from losses. Pyrethroids are the only type of insecticide designated for the control of RSSW; however, instances of pyrethroid insecticide ineffectiveness against RSSW have been annually reported to entomologists at South Dakota State University since 2017. The biological bases of insecticide resistance are unknown but common mechanisms associated with pyrethroid resistance include general detoxification mechanism driven by cytochrome P450s (CYP450s) as well as mutations in the pyrethroid target, voltage-gated sodium channels (VGSCs). The goal of this study was to determine if the computational analysis of a low-coverage genome assembly is sufficient to identify and characterize genes associated with insecticide resistance which could contribute to pest control research efforts. By using a low-coverage genome assembly, RNA-Seq data, and bioinformatic tools, 40 complete and 33 partial gene models coding for CYP450 as well as a partial gene model coding for VGSC have been identified in the genome of RSSW. Twenty-seven mutation sites, previously associated with the pyrethroid resistance in other insects, have been identified in the VGSC gene of RSSW. The low-coverage genome proved to be a sufficient resource for preliminary studies of gene identification which could bring significant knowledge to subsequent research focusing on insecticide resistance and pest control.

Show moreThe Voxel Transformer (VoTr) is a prominent model in the field of 3D object detection, employing a transformer-based architecture to comprehend long-range voxel relationships through self-attention. However, despite its expanded receptive field, VoTr’s flexibility is constrained by its predefined receptive field. In this paper, we present a Voxel Transformer with Density-Aware Deformable Attention (VoTr-DADA), a novel approach to 3D object detection. VoTr-DADA leverages density-guided deformable attention for a more adaptable receptive field. It efficiently identifies key areas in the input using density features, combining the strengths of both VoTr and Deformable Attention. We introduce the Density-Aware Deformable Attention (DADA) module, which is specifically designed to focus on these crucial areas while adaptively extracting more informative features. Experimental results on the KITTI dataset and the Waymo Open dataset show that our proposed method outperforms the baseline VoTr model in 3D object detection while maintaining a fast inference speed.

Show moreMolecular imaging has revolutionized medical diagnostics by providing detailed insights into biological processes at the molecular level within the living subject. Ultrasound Molecular Imaging (USMI) has emerged as a promising diagnostic imaging modality by utilizing targeted contrast agents to unveil crucial molecular information, including vascular biomarkers associated with cancer and other diseases. Despite its potential, the transition of Ultrasound Contrast Agents (UCA) from preclinical evaluation to FDA-approved clinical use faces challenges due to the short in vivo half-life of Micro-Bubbles (MBs), necessitating repeated administrations for comprehensive assessments. Moreover, conventional ultrasound imaging methods suffer from limited scanning areas and single-target focus, leading to low throughput in preclinical evaluations.This thesis addresses these challenges by proposing a robot-assisted whole-body scanning pipeline for preclinical evaluations in Ultrasound Molecular Imaging. By integrating a robotic arm into the imaging setup, this approach enhances scanning flexibility and precision, enabling scans across the entire body of a mouse. This extension of the imaging time window allows for comprehensive assessments without the need for repeated contrast agent administrations. Additionally, the ability to simultaneously scan multiple targets within the same session significantly increases the throughput of preclinical assessments, thereby improving the efficiency and reliability of Ultrasound Molecular Imaging in clinical translation.

Show moreThis thesis delves into the fascinating and intricate connection between sexual behaviour and architecture, offering a comprehensive exploration of the multifaceted factors that shape human sexuality within the context of built environments. The research is divided into six chapters, each providing a distinct perspective on the complex relationship between sexuality and the spaces we inhabit. Chapter 1 serves as an introduction, setting the stage for the study and highlighting the importance of understanding how architectural design and spatial arrangements can influence and be influenced by human sexual behaviours. Chapter 2, "Milieu and Sexed Bodies," delves into the impact of environmental stimuli on sexual arousal. By examining how architectural elements, aesthetics, and spatial configurations can elicit eroticism and arousal, this chapter sheds light on the subtle ways in which built environments interact with our intimate desires. Furthermore, it delves into the psychological aspects of fetishism and voyeurism, exploring how these sexual behaviours find expression within architectural settings. Chapter 3, titled "Sexual Behaviour," delves into the profound influence of history on human sexuality. It examines how cultural norms, religious beliefs, and social backgrounds have shaped and continue to shape sexual attitudes and behaviours across different societies and time periods. The chapter also explores the concept of polymorphous behaviour, emphasizing how architecture can create spaces that cater to diverse expressions of human sexuality. Additionally, it investigates the impact of queer spaces, highlighting the significance of inclusive design in fostering a sense of belonging and acceptance for individuals with diverse sexual identities. Chapter 4 turns its attention to "Mediated Sexuality," offering a historical analysis of how various forms of media have played a pivotal role in shaping sexual attitudes and behaviours. From ancient art to contemporary pornography, this chapter explores how media representations have influenced perceptions of sexuality, and it examines the emergence of pornomodernism, a cultural phenomenon impacting both media and architectural expressions of eroticism. Moreover, it investigates how architecture has incorporated and responded to the eroticized spaces depicted in media. Chapter 5 focuses on the "Coital Environment," a fascinating aspect of architecture that intertwines with sexual behaviour. This chapter delves into the realm of sex tourism, examining how certain destinations and spaces have become associated with sexual encounters. It analyses the design and function of dedicated places for sex within architectural contexts, providing insights into the factors that influence the creation and acceptance of such spaces in different societies. Finally, Chapter 6 presents a comprehensive "Conclusion," synthesizing the key findings from the preceding chapters. It emphasizes the critical role that architecture plays in shaping human sexual behaviours and highlights the social and cultural implications of design decisions in built environments. The chapter concludes with reflections on the significance of creating inclusive and supportive spaces that celebrate and embrace diverse sexual identities and experiences, paving the way for more empathetic and human-centric architectural design in the future. In conclusion, this thesis offers a profound exploration of sexual behaviour and architecture, shedding light on the intricate interplay of environmental stimuli, historical influences, and mediated sexuality in shaping our intimate experiences within the spaces we inhabit. It serves as a valuable resource for architects, urban planners, social scientists, and anyone interested in creating environments that foster a positive and inclusive approach to human sexuality.

Show moreArtificial Intelligence (AI) holds a great promise in the healthcare. It provides a variety of advantages with its application in clinical diagnosis, disease prediction, and treatment, with such interests intensifying in the medical image field. AI can automate various cumbersome data processing techniques in medical imaging such as segmentation of left ventricular chambers and image-based classification of diseases. However, full clinical implementation and adaptation of emerging AI-based tools face challenges due to the inherently opaque nature of such AI algorithms based on Deep Neural Networks (DNN), for which computer-trained bias is not only difficult to detect by physician users but is also difficult to safely design in software development. In this work, we examine AI application in Cardiac Magnetic Resonance (CMR) using an automated image classification task, and thereby propose an AI quality control framework design that differentially evaluates the black-box DNN via carefully prepared input data with shape and fidelity variations to probe system responses to these variations. Two variants of the Visual Geometric Graphics with 19 neural layers (VGG19) was used for classification, with a total of 60,000 CMR images. Findings from this work provides insights on the importance of quality training data preparation and demonstrates the importance of data shape variability. It also provides gateway for computation performance optimization in training and validation time.

Show moreThis study aimed to verify that whether a low-coverage genome can work as an effective approach to isolate Lepidopteran microsatellites. As microsatellites are useful tool to study population genetics, and there are many Lepidopteran agriculture pests which can cause huge economic damages every year, additionally, Lepidoptera have abundant similar flanking sequences making it difficult to develop reliable microsatellites. However, there are not enough published genomes of Lepidoptera species. If low-coverage Lepidopteran genomes can be used to isolate reliable microsatellites, the low-coverage genomes would be an effective and economical approach for microsatellites isolation, because low-coverage genome sequencing is much cheaper and less time-consuming than the published genome sequencing.
