Defining A Cyber Operations Performance Framework Via Computational Modeling, Briant Becote

Masters Theses & Doctoral Dissertations

Cyber operations are influenced by a wide range of environmental characteristics, strategic policies, organizational procedures, complex networks, and the individuals who attack and defend these cyber battlegrounds. While no two cyber operations are identical, leveraging the power of computational modeling will enable decision-makers to understand and evaluate the effect of these influences prior to their impact on mission success. Given the complexity of these influences, this research proposes an agent-based modeling framework that will result in an operational performance dashboard for user analysis. To account for cyber team behavioral characteristics, this research includes the development and validation of the Cyber …

Computer Information Systems Faculty Publications (Archived)

Lung cancer is a common type of cancer that causes death if not detected
early enough. Doctors use computed tomography (CT) images to diagnose
lung cancer. The accuracy of the diagnosis relies highly on the doctor's
expertise. Recently, clinical decision support systems based on deep learning
valuable recommendations to doctors in their diagnoses. In this paper, we
present several deep learning models to detect non-small cell lung cancer in
CT images and differentiate its main subtypes namely adenocarcinoma,
large cell carcinoma, and squamous cell carcinoma. We adopted standard
convolutional neural networks (CNN), visual geometry group-16 (VGG16),
and VGG19. Besides, we …

Quantum Copyright Law: Schrodinger's Cat, Banksy's Shredder, And Art On The Edge, Richard H. Chused

Articles & Chapters

An object has been assembled by artists I know that presents a fascinating set of conundrums about the relationships between quantum physics, shredders, random surprises, the value of art, and copyright law. Seems fantastical, right? And so it is. The object of concern is a metal box a little under four feet tall, about eighteen inches deep, and a bit less than three feet wide. The box is welded together along all twelve of its edges. It has an opening across one side. And there is a small control panel on top. Before the box was welded shut, a set …

Trauma Presentation Among Latinx/Hispanic Subgroups, Ana Paula Leao De Camargo

Theses and Dissertations

Hispanics/Latinos are the fastest-growing minority group in the United States and are estimated to compose half of the American population by 2060 if growing trends follow current levels. It has been suggested that Latinx/Hispanics perceive and react to adverse experiences with somatization, which is highly comorbid with Post-traumatic Stress Disorder (PTSD) symptoms (van der Kolk, et al 1996). This study surveyed 451 participants from which 88% identified as being Hispanic or Latinas, 2.7% identified as being Black Hispanic/Black Latina, and 9.3% identified as having mixed ethnicities including Hispanic/Latina. Regarding place of birth, 431 respondents (95.6%) identified being born in Continental …

Chiral Photocurrent In A Quasi-1d Tis3 (001) Phototransistor, Simeon J. Gilbert, Mingxing Li, Jia-Shiang Chen, Hemian Yi, Alexey Lipatov, Jose Avila, Alexander Sinitskii, Maria C. Asensio, Peter A. Dowben, Andrew J. Yost

Department of Physics and Astronomy: Faculty Publications

The presence of in-plane chiral effects, hence spin–orbit coupling, is evident in the changes in the photocurrent produced in a TiS₃(001) field-effect phototransistor with left versus right circularly polarized light. The direction of the photocurrent is protected by the presence of strong spin–orbit coupling and the anisotropy of the band structure as indicated in NanoARPES measurements. Dark electronic transport measurements indicate that TiS₃ is n-type and has an electron mobility in the range of 1–6 cm²V⁻¹s⁻¹. I–V measurements under laser illumination indicate the photocurrent exhibits a bias directionality dependence, reminiscent of …

The Role Of Teleradiology During Covid-19 Outbreak: Saudi Radiologists’ Perspectives, Shrooq T. Al-Dahery, Walaa M. Alsharif, Fatima H. Alamri, Shahad A. Nawawi, Wed K. Mofti, Fahad H. Alhazmi, Khalid M. Alshamrani, Awadia G. Suliman, Abdulaziz A. Qurashi

Saudi Medical Journal

Objectives: To evaluate the role of teleradiology during the COVID-19 pandemic from Saudi radiologists’ perspectives to improve the radiology quality service. Methods: A cross-sectional study was carried out in Saudi Arabia among radiologists working at local hospitals from October to November 2021. It contains 21 questions involved demographic information; general information on teleradiology services; and the impact of teleradiology during COVID-19. One-way ANOVA was used to compare demographic groups. Chi-square test was used to compare demographic groups regarding their distribution of responses. All tests were carried out <0.05 level of significance. Results: A total of 102 radiologists participated in this study (56% males, 44% females), 58.8% of them were sub-specialized in chest radiology. Regarding the general status of teleradiology, 69.6% of participants believed that teleradiology is a helpful tool for imaging interpretation. However, 44% of them were uncertain on the impact of teleradiology on patients’ confidentiality. Approximately 87% of participants agreed that there is a positive contribution of teleradiology during COVID-19, which enables decreasing risk of infection and workload. There was a significant difference between professional degrees and overall participant responses ( p <0.05). Academicians agreed that it enhances radiology departments’ work (mean=17.78, SD=1.86). Conclusion: Concerns raised on complicated cases that require physical presence of patients, cannot be performed by teleradiology. Additionally, it might provide insufficient communication with other professionals to discuss images.

Using Virtual Simulations Of Future Extreme Weather Events To Communicate Climate Change Risk, Terry Van Gevelt, Brian G. Mcadoo, Jie Yang, Linlin Li, Fiona Williamson, Alex Scollay, Aileen Lam, Kwan Nok Chan, Adam D. Switzer

Research Collection College of Integrative Studies

Virtual simulations of future extreme weather events may prove an effective vehicle for climate change risk communication. To test this, we created a 3D virtual simulation of a future tropical cyclone amplified by climate change. Using an experimental framework, we isolated the effect of our simulation on risk perceptions and individual mitigation behaviour for a representative sample (n = 1507) of the general public in Hong Kong. We find that exposure to our simulation is systematically associated with a relatively small decrease in risk perceptions and individual mitigation behaviour. We suggest that this is likely due to climate change scepticism, …

The City Never Sleeps: But When Will Investment Banks Wake Up To The Climate Crisis?, Theodor Florian Cojoianu, Andrea G. F. Hoepner, Fabiola I. Schneider, Michael Urban, Anh Vu, Dariusz Wojcik

Research Collection College of Integrative Studies

Using a global dataset of over 840,000 equity, bond and syndicated loan investment banking deals, we build the fossil fuel investment brokerage profile of financial centres worldwide between 2000 and 2018. We also study whether city-level fossil fuel divestment commitments and country-level green banking policies impact the profile of fossil fuel financial centres over our study timeframe. We find that several financial centres shift their fossil fuel investment brokerage profiles substantially, including the asset classes in which they are active. However, we do not find any evidence that this is driven by city-level divestment commitments. In contrast, we find that …

Research Collection College of Integrative Studies

This paper describes a dataset collected by infrared thermography, a non-contact, non-intrusive technique to acquire data and analyze the built environment in various aspects. While most studies focus on the city and building scales, an observatory installed on a rooftop provides high temporal and spatial resolution observations with dynamic interactions on the district scale. The rooftop infrared thermography observatory with a multi-modal platform capable of assessing a wide range of dynamic processes in urban systems was deployed in Singapore. It was placed on the top of two buildings that overlook the outdoor context of the National University of Singapore campus. …

Curcumin Release From Biomaterials For Enhanced Tissue Regeneration Following Injury Or Disease, Adelle E. Hamilton, Ryan J. Gilbert

Chemical and Biochemical Engineering Faculty Research & Creative Works

Curcumin, a bioactive phenol derived from turmeric, is an antioxidant, anti-inflammatory, and antibacterial molecule. Although curcumin exhibits beneficial effects in its innate form, it is highly hydrophobic, which leads to poor water solubility and, consequently, low bioavailability. The lack of bioavailability limits curcumin's effectiveness as a treatment and restricts its use in clinical applications. Furthermore, to achieve beneficial, clinically relevant results, high doses of curcumin are required for systemic administration. Many researchers have utilized biomaterial carriers, including electrospun fibers, nanoparticles, hydrogels, and composite scaffolds, to overcome curcumin's principle therapeutic limitation of low bioavailability. By using biomaterials to deliver curcumin directly …

Seeing Like A Chocolate City: Reimagining Detroit’S Future Through Its Past, Sheila R. Foster

Georgetown Law Faculty Publications and Other Works

This essay is part of an online symposium on Michelle Wilde Anderson's “The Fight to Save the Town.” In it, Anderson captures how the rise and fall of Detroit maps onto so many other important cultural, political, social, and economic moments of the twentieth century. As Anderson rightly notes, many of the ways in which the city’s history is commonly told represent a “white gaze on Detroit.” What this narrative often leaves out is the critical role of the Black middle and professional class in stabilizing or holding up the city during the period often associated with the city’s decline. …

Permission, Prohibition, And Dynamism, John Thrasher

Philosophy Faculty Books and Book Chapters

Modern, open societies are characterized by growth and dynamism. To many environmentalists, however, it is this very commitment to growth and change that put modern societies at odds with the values of environmental protection. Many argue that the uncertainty that comes from growth endangers the environment, with the implication being that we should adopt general prohibitions rules like the “Precautionary Principle,” which prohibits economic activity unless it can be proven to have no substantial environmental impact. I argue that this conclusion is largely mistaken. Dynamism is so important and in opposition to general prohibition rules that we should avoid them …

The Death Of The Legal Subject, Katrina Geddes

Vanderbilt Journal of Entertainment & Technology Law

The law is often engaged in prediction. In the calculation of tort damages, for example, a judge will consider what the tort victim’s likely future earnings would have been, but for their particular injury. Similarly, when considering injunctive relief, a judge will assess whether the plaintiff is likely to suffer irreparable harm if a preliminary injunction is not granted. And for the purposes of a child custody evaluation, a judge will consider which parent will provide an environment that is in the best interests of the child.

Relative to other areas of law, criminal law is oversaturated with prediction. Almost …

Co-Authorship Between Photographers And Portrait Subjects, Molly Torsen Stech

Vanderbilt Journal of Entertainment & Technology Law

work with the intent of merging their contributions into inseparable or interdependent parts of a unitary whole, the authors are considered joint authors. For photographic works, judicial precedent establishes that the creative contributions necessary to support a copyright claim include the author’s choices concerning elements such as lighting, pose, garments, background, facial expression, and angle. In many visual works, however, those creative elements are determined not solely by a photographer, but also by the subject, who can sulk or smile, stand with good posture or stoop, and be situated in full light or obfuscated by shadow, among many other options. …

The Data Trust Solution To Data Sharing Problems, Kimberly A. Houser, John W. Bagby

Vanderbilt Journal of Entertainment & Technology Law

A small number of large companies hold most of the world’s data. Once in the hands of these companies, data subjects have little control over the use and sharing of their data. Additionally, this data is not generally available to small and medium enterprises or organizations who seek to use it for social good. A number of solutions have been proposed to limit Big Tech “power,” including antitrust actions and stricter privacy laws, but these measures are not likely to address both the oversharing and under-sharing of personal data. Although the data trust concept is being actively explored in the …

Coming-Of-Age Of Teenage Female Arab Gothic Fiction: A Feminist Semiotic Study, Zoe Hurley, Zeina Hojeij

All Works

This feminist semiotic study explores the folkloric imaginary of the jinn in the context of children’s and young adults’ Arab Gothic literature. Across the Middle East, the jinn is a common trope in literature, folklore and oral storytelling who, in diegetic terms, can manifest as the Gothic figure of an aging female, deranged older woman or succubus (known as sa’lawwa in Arabic). In this study, a novel feminist semiotic framework is developed to explore the extent to which the Gothic female succubus either haunts or liberates Arab girls’ coming-of-age fictions. This issue is addressed via a feminist semiotic reading of …

Alignment-Enriched Tuning For Patch-Level Pre-Trained Document Image Models, Lei Wang, Jiabang He, Xing Xu, Ning Liu, Hui Liu

Research Collection School Of Computing and Information Systems

Alignment between image and text has shown promising im provements on patch-level pre-trained document image mod els. However, investigating more effective or finer-grained alignment techniques during pre-training requires a large amount of computation cost and time. Thus, a question natu rally arises: Could we fine-tune the pre-trained models adap tive to downstream tasks with alignment objectives and achieve comparable or better performance? In this paper, we pro pose a new model architecture with alignment-enriched tuning (dubbed AETNet) upon pre-trained document image models, to adapt downstream tasks with the joint task-specific super vised and alignment-aware contrastive objective. Specifically, weintroduce an extra …

Research Collection School Of Computing and Information Systems

With the increasing adoption of services-oriented computing and cloud computing technologies, web APIs have become the fundamental building blocks for constructing software applications. Web APIs are developed and published on the internet. The functionality of web APIs can be used to facilitate the development of software applications. There are numerous studies on retrieving and recommending candidate web APIs based on user requirements from a large set of web APIs. However, there are very limited studies on the features of web APIs that make them more likely to be used and the issues of using web APIs in practice. Moreover, users' …
