Computational Tools For Protein Classification In Metagenomes, Fawad Ullah

Dissertations, Master's Theses and Master's Reports

Advances in genomic sequencing have dramatically increased the amount and the speed at which genomic data is being generated. These technological advances have enabled the ability to profile the genetic information of organisms and communities at unprecedented scales. Many methods have been developed to identify and classify genes within these datasets. However, many generic pipelines for gene annotation struggle to accurately predict specific protein classes that may not be represented in their databases. Two major challenges exist for classification of specific protein classes in metagenomic databases. The first is the fact that many metagenomic assemblies are highly fragmented with many …

Fine Root And Ectomycorrhizal Functional Traits Of Quercus Rubra Populations From Across A Latitudinal Gradient, Emma L. Shedd

Dissertations, Master's Theses and Master's Reports

Forests are increasingly considered for their carbon sequestration value, but their ability to store carbon is dependent on a close balance between carbon fluxes into and out of ecosystems. Nutrient uptake of roots and associated symbiotic communities results in respiratory carbon release, which is projected to increase with warming and represents a substantial uncertainty in earth system modeling. Traits that are functionally related to nutrient uptake can be used to estimate carbon fluxes, but our understanding of the trade-offs that govern root, and especially fungal, traits is limited. Fine roots in surface soils are responsible for the bulk of plant …

Empowering Young Learners From Diverse Economic Backgrounds, Tonya Wilson-Story

Graduate Research Papers

This paper explores the importance and benefits of empowering young learners from diverse economic backgrounds through goal setting, specifically focusing on students enrolled in an urban school serving a highly diverse population. Over time, students have changed neurologically and behaviorally—shaped in part by the influence of technology, which has affected how they process information and maintain attention. As a result, today’s students learn differently than in previous generations. Research shows that many young learners now enter school with only half the vocabulary of their middle-class peers (Wentzel, 2020), underscoring the urgent need for new instructional approaches that effectively engage and …

Walk In The Woods (2023) By Nikki Grimes, Maughn Rollins Gregory

Picture Books

An unnamed Black boy walks in the woods near his home a week after his father’s funeral. Because the boy knows how to be mindful in nature—to move slowly, step carefully, and pay close attention—he becomes more connected to the woods and the creatures in it. Rediscovering is his father’s legacy of ecstatic, aesthetic reverence for nature begins to assuage the boy's anger-tinged grief.

Big Tracks, Little Tracks: Following Animal Prints (1999) By Millicent E. Selsam, Maughn Rollins Gregory

Picture Books

Coming up with the most reasonable explanation of the available clues is something we all do on a daily basis. This book describes animal tracks as clues from which children can make inferences about what kind of animal left them and what they were doing when they did.

Possum That Didn't (1950/2016) By Arthur Frank Tashlin, Maughn Rollins Gregory, Peter Shea

Picture Books

The possum ‘that didn’t’ is a very contented animal who smiles in sunshine and rain, but when a group of human picnickers spot him hanging by his tail, they read his smile as a frown and call him stupid for insisting that he is happy. They decide to take him to the city to find amusement and, because he won’t climb down from the tree, they excavate it and transport tree and hanging possum together. Frank Tashlin's book goes philosophical in two different directions. One is the direction of satire: We laugh at humans taking a possum to a nightclub, …

How Beautiful (2021) By Antonella Capetti, Maughn Rollins Gregory

Picture Books

The question of what is and isn’t beautiful occurs to the caterpillar in this elaborate picture book when a giant Unknown Thing (human) lifts him out of his familiar leaf bed world and tells him, “You’re so beautiful.” The caterpillar wonders, “But what does beautiful mean?” The question leads him on a day-long trek through the forest, where other animals offer a variety of perplexing answers.

Depth Of The Lake And The Height Of The Sky (2017) By Kim Jihyun, Megan Jane Laverty

Picture Books

The Depth of the Lake and the Height of the Sky (2017) is KimJihyun’s first picture book; it is composed entirely of pictures. It “tells” the story of a young boy and his dog who spend a day swimming and sunbathing at a lake that is within walking distance from his grandparents' home, whom he is visiting with his parents. At first glance, the story might seem unremarkable, recounting an experience familiar to many. However, Kim’s illustrations challenge this assumption by drawing us into the boy’s encounter with nature. She creates a visual journey that guides us through a perceptual …

Elementary Teachers’ Experiences Of Implementing Culturally Responsive And Inclusive Education In New York State, Grace Pai

Publications and Research

Many states in the United States have adopted culturally responsive sustaining education (CRSE) as a pedagogical framework to promote inclusive education and positive student outcomes for all students, including those from marginalized groups. Yet there is a paucity of knowledge on teachers’ attitudes towards and experiences of implementing these initiatives. This study draws on survey data to explore how urban and rural/suburban elementary school teachers across the state of New York understand and implement the state’s CRSE framework. Results show that although CRSE is not necessarily a top priority of many schools across the state, teachers generally have positive perceptions …

Arithmetic Ramsey Theory In Algebraic Settings, Gauree Wathodkar

Electronic Theses and Dissertations

Arithmetic Ramsey theory is an area of combinatorics that deals with finding structures in large subsets of integers, dating back to at least Hilbert (1892). One of the early results in this area is Schur’s theorem (1917) that pioneered the concept of partition regularity. In 1933, Schur’s student Rado generalized his theorem and proposed a conjecture for partition regular equations. This was settled by Deuber in 1973. The first part of this dissertation is to generalize this conjecture in infinite integral domains.

For non-partition regular equations Rado gave a Boundedness conjecture in the integers. While this conjecture is still open, …

Foreign Object Detection System Development Using Edge Devices Integrated With Quadcopter Autonomous Tracking, Chi-Chia Huang, Ching-Hung Lee

Journal of Marine Science and Technology–Taiwan

This study proposes an all-weather autonomous foreign-object detection system capable of operating in low-light environments. We used a highly mobile quadcopter equipped with an edge-computing device as the inspection platform. On the software side, we integrated a low-light image enhancement model, a path-tracking algorithm, and a foreign object detection model to achieve rapid object detection. A lightweight, low-light image-enhancement model reduces the need for additional lighting equipment, thereby enabling reliable detection under low-light conditions. The path-tracking algorithm integrates a lightweight semantic segmentation model with traditional image-processing techniques to establish flight paths efficiently and reliably. The foreign-object detection component employs state-of-the-art …

Optimization Of Underactuated Ship Sliding Mode Controller Based On The Ddpg Algorithm, Lin Ma, Mingzhe Qi, Shicai Chen, Hongwei Bian, Jian Zhang

Journal of Marine Science and Technology–Taiwan

Due to the development of ship intelligence, the demand for precise controllers is increasing day by day. In traditional design, the trial-and-error method often leads to the use of inaccurate controller parameters, causing oscillations when environmental disturbances are present. To address these issues, this study introduces deep learning to optimize the controller parameters, particularly those used for sliding mode controllers in underactuated ships. We adopt the Deep Deterministic Policy Gradient (DDPG) algorithm based on the Actor Critic framework. By freely setting the reward function to match the control objective, the trained model can output more accurate controller parameters, with the …

Artificial Intelligence And Seeing The Invisible In Arts - From The Wane Of Axiality And Symmetry To The Wax Of Invisibility And Emptiness, M. Samir Abou El-Seoud

Computer Science

Function has been always an important driver in architectural design. It is the request to generate form directly from purpose and utility. In 1896, Louis Sullivan projected that ‘form follows function’ and that the beauty of a building derives directly from its function and not from references of the built heritage. The assumption was that beauty would naturally derive from design once functional requirements are met. Thus, fitness for purpose equals beauty. In 1908, Adolf Loos even went so far as to ask for the total abandonment of decoration. In 1947, Mies van der Rohe made his paradigm shift, function …

Heifer development on dormant rangelands offers a cost-effective alternative to feedlot or drylot systems. However, traditional bunk supplementation methods often result in uneven intake, inefficient feed use, and ecological degradation around static feeding sites. This thesis evaluated the integration of precision livestock technologies and a dynamic Range Supplementation Model to improve individual animal performance, weight uniformity, and rangeland sustainability in extensive heifer development systems in the Northern Great Plains. The first study involved a seven-month trial (November 2023–May 2024) with 50 yearling Angus heifers grazing dormant native rangelands at the SDSU Cottonwood Field Station. Heifers were stratified into two treatments: …

Functional Data Analysis And Spatial Analysis For On-Farm Strip Trials, Peter Claussen

Electronic Theses and Dissertations

Collaborative on-farm trials of agronomic practices have been an established method of interaction between researchers and their target audience (the farmers). With the advent of precision agriculture practices, the on-farm strip trial has become a popular method of collaborative research. Precision agriculture practices allows farmers to precisely control the application of an agronomic product or practice to specific strips in a cropland, and to leave as standard practice strips, or check strips, intermingled with the test strips. In spite of their popularity, there has been little development in the methods of analyzing strip trials. In this thesis, two examples of …

The "Not Seen" Effect Of International Financial Centers: Innovation In The Global Financial Ecosystem, Charlotte Ku, Andrew P. Morriss

South Carolina Journal of International Law and Business

International Financial Centers (IFCs) are hubs of legal and financial innovation, developing specialized frameworks that facilitate cross-border investment, enhance global capital mobility, and support economic growth. Through jurisdictional competition, professional clustering, and adaptive regulatory frameworks, IFCs have pioneered legal structures that enable enterprises of all sizes to participate in the global economy. Using case studies of the International Business Company, the Limited Liability Company, the Protected Cell Company, and advances in trust law and applying the theoretical frameworks of social scientist Richard Florida and psychologist Mihalyi Csikszentmihalyi, this article illustrates how IFCs serve as laboratories for financial experimentation, generating widely …

Navigating The Seas Of History In International Law, Valentina Vadi

South Carolina Journal of International Law and Business

Inquiries into questions of time, history, and international law have recently come to the fore. So far, however, many studies have only examined developments in international law from a temporally and thematically fragmented, brief, and narrow perspective. Due to international law’s growing normative and institutional fragmentation and emphasis on specific crises, episodes, and events, many analyses focus on transient trends and particular facets of international law. This study suggests an alternative to these constrained viewpoints: a thorough, multilayered, and broad perspective to questions of international law, drawing on Fernand Braudel’s tripartite theory of time.

Braudel’s theory of time provides valuable …
