Optical Fiber Sensors Using Vernier Effect In Cascaded Fiber Interferometers, Zhouchen Wang Feb 2026

Optical Fiber Sensors Using Vernier Effect In Cascaded Fiber Interferometers, Zhouchen Wang

Dissertations

The optical Vernier effect has emerged as a powerful tool to enhance the sensitivity of optical fiber interferometer-based sensors, opening new opportunities for developing highly sensitive fiber sensing systems. Optical fiber interferometric sensors based on the Vernier effect are widely used for various applications due to their ultra-compact size, high sensitivity, immunity to electromagnetic interference, electrical isolation, resistance to harsh environments, flexibility, multiplexing capability, and remote operation. The aim of this doctoral thesis was to gain a deeper fundamental understanding of the Vernier effect in optical fiber structures and to develop and investigate a series of novel Vernier effect optical …


Recommendations For Developing A Regulatory Sandbox And A Comprehensive Legal Framework For Fintech In Vietnam - Part I, Sue M. Altmeyer, Phan Dang Hai Feb 2026

Recommendations For Developing A Regulatory Sandbox And A Comprehensive Legal Framework For Fintech In Vietnam - Part I, Sue M. Altmeyer, Phan Dang Hai

Akron Law Faculty Publications

Fintech, a product of the 4.0 revolution, has experienced rapid growth in Vietnam, attracting significant attention from investors and government agencies. In encouraging innovation, the authors write, the need for a practical legal framework to regulate fintech activities has become a critical issue. The authors believe that this new legal framework should include a regulatory sandbox, which would allow fintech startups to test their products in a controlled environment, helping to mitigate risks, foster creativity, and enhance regulatory oversight. This two-part article discusses challenges in creating and implementing a regulatory sandbox and provides recommendations for overcoming these hurdles. This first …

Juvenile hormone (JH) is essential for maintaining juvenile status and promoting reproduction in insects, yet the transcriptional regulation of JH biosynthesis remains poorly understood. Previous transcriptomic studies of the Drosophila ring gland—which is composed of the corpus allatum (CA), prothoracic gland (PG), and corpora cardiaca (CC)—have treated the ring gland as a single tissue. As a result, these approaches lacked the resolution necessary to dissect JH biosynthesis and its regulation in a cell-type-specific manner. To overcome this limitation, we performed single-cell RNA sequencing (scRNA-seq) of 7,919 cells isolated from the larval ring glands. This analysis resolved distinct transcriptional profiles for …

Dysregulated ribosome biogenesis and p53 mutations are known to play oncogenic roles in various cancers, including pancreatic cancer. In this study, we demonstrated the therapeutic potential of BMH-21, a pharmacologic inhibitor of RNA polymerase I, against pancreatic cancer by uncovering a novel molecular mechanism involving RPA194-mediated ubiquitination of mutant p53 without affecting the ubiquitination of wild-type p53. Our key findings are that (i) BMH-21 selectively induces apoptosis and cell growth inhibition of pancreatic cancer cells with no effect on normal human pancreatic ductal epithelial cells; (ii) BMH-21 degrades RPA194; (iii) BMH-21 inhibits recruitment of both RPA194 and RPA135 on rDNA …


Cellstaar: Incorporating Single-Cell-Sequencing-Based Functional Data To Boost Power In Rare Variant Association Testing Of Noncoding Regions, Eric Van Buren, Yi Zhang, Xihao Li, Margaret Sunitha Selvaraj, Zilin Li, Nicholette D.

Palmer, Donna K. Arnett, John Blangero, Eric Boerwinkle, Joanne E. Curran, Ravi Duggirala

School of Medicine Publications

Understanding how rare genetic variants influence complex traits remains a major challenge, particularly when these variants lie in noncoding regions of the genome. The effects of variants within candidate cis-regulatory elements (cCREs) often depend on the cell type, making interpretation difficult. Here we introduce cellSTAAR, which integrates whole-genome sequencing data with single-cell assay for transposase-accessible chromatin using sequencing data to capture variability in chromatin accessibility across cell types via the construction of cell-type-specific functional annotations and regulatory elements. To reflect the uncertainty in cCRE–gene linking, cellSTAAR uses a comprehensive strategy to link cCREs to their target genes. We applied …

Accurate diagnostics are essential for disease control and elimination efforts. However, access to diagnostics for neglected tropical diseases (NTDs) is hindered by limited healthcare infrastructure in many NTD-endemic regions, as well as by reliance on time- and labor-intensive diagnostic methods, such as smear microscopy. New diagnostic tools that are portable, rapid, low-cost, and meet World Health Organization (WHO) sensitivity and specificity targets are urgently needed to accelerate NTD control and elimination programs. Here, we introduce the NTDscope, a portable microscopy platform that enables point-of-care imaging and automated detection of parasites and other pathogens in patient samples. The NTDscope builds on …


Dna Stability In Aqueous Solutions: A Case Study On Poly A - Poly T Duplex Using Molecular Dynamics Simulations, Haripriya Chennuru Feb 2026

Dna Stability In Aqueous Solutions: A Case Study On Poly A - Poly T Duplex Using Molecular Dynamics Simulations, Haripriya Chennuru

Biochemistry and Molecular Biology

This thesis relies on molecular dynamics (MD) simulations, which apply the AMBER software package to analyze the structural stability, energetics, and dynamics of Poly A - Poly T DNA duplexes. This work is mainly concerned with testing configurations of non-bonded interaction cutoffs (12 Å and 15 Å) on the Generalized Born solvation models (IGB1 and IGB2) to determine the most appropriate conditions regarding computation time and physical reliability in DNA molecular dynamics. The solvation models enable effective simulation of solvent effects, facilitating the calculation of simulation parameters to evaluate structural stability within different environmental conditions. Overall, the performance indicates that …


Age And Sex Impact The Role Of Thrombospondin-2 And Thrombospondin-5 In Response To Hindlimb Ischemia, Irene Helenowski, Ashley Peters, Melissa Rangel, Corinne Bunn Md, Xuerong Wang, Kristopher Maier, Vivian Gahtan Feb 2026

Age And Sex Impact The Role Of Thrombospondin-2 And Thrombospondin-5 In Response To Hindlimb Ischemia, Irene Helenowski, Ashley Peters, Melissa Rangel, Corinne Bunn Md, Xuerong Wang, Kristopher Maier, Vivian Gahtan

Biostatistics Collaborative Core: Faculty Publications and Other Works

Peripheral arterial disease progression to critical limb ischemia remains a significant burden in the aged, necessitating revascularization. Therapies to enhance neovascularization, such as angiogenesis or arteriogenesis, may provide an option for patients not suitable for surgery. The thrombospondins (TSPs) are secreted matricellular glycoproteins, with TSP-1, TSP-2, and TSP-5 implicated in neovascularization. Currently, there is little data regarding the effects of TSP-2, TSP-5, sex, and aging on angiogenesis and arteriogenesis. In vitro, the effect of TSP-2 or TSP-5 on early or late passage endothelial cell (EC) tubule formation or disruption was assessed. In vivo, angiogenesis, and arteriogenesis in male and female, …

Species-Dependent Gazing Behavior Of Emotional Facial Expressions In Dogs (Canis Familiaris) And Adult Humans (Homo Sapiens)., Heini Törnqvist, Gray S. Atherton, Liam Cross, Sanni Somppi, Jarkko Hautala, Miiamaaria V. Kujala Feb 2026

Species-Dependent Gazing Behavior Of Emotional Facial Expressions In Dogs (Canis Familiaris) And Adult Humans (Homo Sapiens)., Heini Törnqvist, Gray S. Atherton, Liam Cross, Sanni Somppi, Jarkko Hautala, Miiamaaria V. Kujala

School of Psychology

Emotional expressions play an important part in social communication of dogs and humans, but comparative studies between dogs and humans are rare. In addition, little is known about how emotions are perceived across species and how attention is divided among different parts of faces. Here, we compared the gazing behavior of dogs and adult humans toward emotional dog and human facial expressions. Dogs mostly gazed at the eye and nose areas, whereas the humans’ focus also included the mouth area. The gazing behavior of both species was affected by the facial expressions and species presented, and they gazed at emotional …
