In mammals, trait variation is often reported to be greater among males than females. However, to date, mainly only morphological traits have been studied. Energy expenditure represents the metabolic costs of multiple physical, physiological, and behavioral traits. Energy expenditure could exhibit particularly high greater male variation through a cumulative effect if those traits mostly exhibit greater male variation, or a lack of greater male variation if many of them do not. Sex differences in energy expenditure variation have been little explored. We analyzed a large database on energy expenditure in adult humans (1494 males and 3108 females) to investigate whether …

Celebrity Politics In The American South: The Case Of Ben “Cooter” Jones, Richard T. Longoria

Political Science Faculty Publications

Celebrities get involved in American politics as activists and candidates for office. The literature suggests that celebrities have many advantages over traditional political candidates. However, the case of Ben Jones, “Cooter” from The Dukes of Hazzard, suggests that fame is not enough to win elections. The political environment is the decisive factor in determining whether a celebrity candidate wins or loses an election. The South’s realignment from Democrat to Republican made it difficult for Democrat Ben Jones to succeed in a changing South. Like other celebrities that lost the fundraising battle Jones lost several bids for office. Celebrities, like Fred …

Student Publications

Background: Epilepsy is one of the most common neurological disorders in childhood. However, classical antiepileptic drugs are linked with drug toxicity and cognitive function impairment in children. Hence, it is essential to develop a novel therapy to solve this problem. Currently, studies indicate regulating the nuclear factor-erythroid 2-related factor 2 (Nrf2)-mediated ferroptosis pathway represents a potential advanced therapy for seizures. Hence, the present study aimed to explore whether quercetin, a natural polyphenol, could alleviate seizure-induced neuron death and preserve cognitive function by inhibiting Nrf2-mediated ferroptosis.

Methods: Kainic acid-induced epileptic mice model, morris water maze (MWM) test, cell counting kit-8 (CCK-8) …

A Mesh-Free Method Using Piecewise Deep Neural Network For Elliptic Interface Problems, Cuiyu He, Xiaozhe Hu, Lin Mu

School of Mathematical & Statistical Sciences Faculty Publications

In this paper, we propose a novel mesh-free numerical method for solving the elliptic interface problems based on deep learning. We approximate the solution by the neural networks and, since the solution may change dramatically across the interface, we employ different neural networks for each sub-domain. By reformulating the interface problem as a least-squares problem, we discretize the objective function using mean squared error via sampling and solve the proposed deep least-squares method by standard training algorithms such as stochastic gradient descent. The discretized objective function utilizes only the point-wise information on the sampling points and thus no underlying mesh …

Superficial Solitary Fibrous Tumor Masquerading As A Dermoid Cyst: A Case Report, Michael Foss, Charles Dunn, Etan Marks, Rajiv Nathoo

GME Publications

Background: Solitary fibrous tumors (SFTs) are relatively rare spindle cell neoplasms uncommonly seen in dermatology practice. Initially discovered as a pleural tumor, SFTs have also been found in extra-pleural sites including the skin and soft tissues. When arising within the dermis or subcutis they are termed superficial SFTs, where they often present as solitary, unilateral, slow growing superficial masses. Histologically, they are composed of spindle cells arranged in a "patternless" pattern with hemangiopericytoma-like vessels dispersed throughout. Historically, CD34, CD99 and Bcl-2 immunohistochemical (IHC) stains were used to differentiate SFTs from other spindle cell neoplasms, however these markers are not entirely …

Police Vehicle Searches And Racial Profiling: An Empirical Study, Griffin Edwards, Stephen Rushin

Fordham Law Review

In 1981, the U.S. Supreme Court held in New York v. Belton that police officers could lawfully search virtually anywhere in a vehicle without a warrant after the arrest of any occupant in the vehicle. Then, in 2009, the Court reversed course in Arizona v. Gant, holding that police could only engage in vehicle searches after such arrests in a smaller number of extenuating circumstances. This series of cases became a flash point for the broader debate about the regulation of policing. Law enforcement groups argued that administratively complex rules, like those established in Gant, risk officer safety. …

Sources And Distribution Of Microplastics In The United Arab Emirates, Rana Zeeshan Habib

Dissertations

Microplastics (plastic pieces size) are an emerging environmental contaminant that is ubiquitously present in terrestrial, aquatic and aerial environments. United Arab Emirates (UAE) is categorized among the highest domestic waste producing countries (on per capita basis) in the world. A large portion of waste ends up in the environment and contains macro-, meso- and microplastics. No comprehensive study has been carried out in the UAE to investigate the abundance, sources, distribution and impact of microplastics on its environment. Therefore, a comprehensive study to analyze the sources and distribution of microplastics in the UAE was urgently needed. The objective of the …

A Tailored Occupational Therapist-Led Vocational Intervention For People With Stroke: Protocol For A Pilot Randomized Controlled Trial, Sophie O'Keefe, Kathryn Radford, Amanda Farrin, Jodi Oakman, Serena Alves-Stein, Geoffrey Cloud, Jacinta Douglas, Mandy Stanley, Natasha A. Lannin

Research outputs 2022 to 2026

Background: Resuming work after stroke is a common goal of working-age adults, yet there are few vocational rehabilitation programs designed to address the unique challenges faced following stroke. The Work intervention was developed to address these gaps. Objective: This paper presents a protocol that outlines the steps that will be undertaken to pilot both the intervention and trial processes for the Work trial. Methods: The Work trial is a 2-arm, prospective, randomized, blinded-assessor study with intention-to-treat analysis. A total of 54 adults of working age who have experienced a stroke <4 months prior will be randomized 1:1 to either (1) an experimental group who will receive a 12-week early vocational intervention (Work intervention) plus usual clinical rehabilitation or (2) a control group who will receive only their usual clinical rehabilitation. Results: Outcomes include study and intervention feasibility and intervention benefit. In addition to evaluating the feasibility of delivering vocational intervention early after stroke, benefit will be assessed by measuring rates of vocational participation and quality-of-life improvements at the 3- and 6-month follow-ups. Process evaluation using data collected during the study, as well as postintervention individual interviews with participants and surveys with trial therapists, will complement quantitative data. Conclusions: The results of the trial will provide details on the feasibility of delivering the Work intervention embedded within the clinical rehabilitation context and inform future trial processes. Pilot data will enable a future definitive trial to determine the clinical effectiveness of vocational rehabilitation when delivered in the early subacute phase of stroke recovery.

Exploring The Dynamics Of Primary Epsteinbarr Virus Infection Using A Novel Rabbit, Narendran Reguraman

Dissertations

Epstein-Barr virus (EBV) is a common herpesvirus asymptomatically carried by over 90% of the world population. However, in certain circumstances, the virus can lead to life-threatening diseases. Although the virus was isolated over 55 years ago, several fundamental aspects of the biology of EBV and the mechanism by which this virus induces pathology remain unknown. One major obstacle has been the lack of a suitable small animal model for EBV infection. We have recently shown that healthy rabbits are susceptible to EBV infection, and the virus establishes long-term latent infection typically seen in humans. The main objective of this dissertation …

Githaiga, J. L. Howard, D. Krause-Jensen, T. Kuwae, Paul S. Lavery, P. I. Macreadie, N. Marbà, Pere Masqué, I. Mazarrasa, T. Miyajima, Oscar Serrano, C. M. Duarte

Research outputs 2022 to 2026

Our knowledge of the factors that can influence the stock of organic carbon (OC) that is stored in the soil of seagrass meadows is evolving, and several causal effects have been used to explain the variation of stocks observed at local to national scales. To gain a global-scale appreciation of the drivers that cause variation in soil OC stocks, we compiled data on published species-specific traits and OC stocks from monospecific and mixed meadows at multiple geomorphological settings. Species identity was recognized as an influential driver of soil OC stocks, despite their large intraspecific variation. The most important seagrass species …

Children’S Identity Work In Daily Singing-Based Music Classes: A Case Study Of An Australian Boys’ School, Jason Goopy

Research outputs 2022 to 2026

Music can be a powerful activity and resource in a child’s ongoing identity construction. Rather than something that people have, musical identities are understood to be something people enact and continually work on. The correlation between musical identities and developing music skills raises serious questions regarding the possibilities and responsibilities for school music education and music teachers to positively contribute to children’s emerging identities. This study investigates how daily singing-based music classes at an Australian boys’ school shape and support children’s identity work. Research was conducted using one-on-one semistructured interviews incorporating a “draw and tell” artifact elicitation technique with seven …

Sohrabi, Manfred R. Raida, Kevin Taddei, Sam Gandy, Colin L. Masters, Pratishtha Chatterjee, Ralph N. Martins, Aibl Research Group

Research outputs 2022 to 2026

Cholesterol levels have been repeatedly linked to Alzheimer's Disease (AD), suggesting that high levels could be detrimental, but this effect is likely attributed to Low-Density Lipoprotein (LDL) cholesterol. On the other hand, High-Density Lipoproteins (HDL) cholesterol levels have been associated with reduced brain amyloidosis and improved cognitive function. However, recent findings have suggested that HDL-functionality, which depends upon the HDL-cargo proteins associated with HDL, rather than HDL levels, appears to be the key factor, suggesting a quality over quantity status. In this report, we have assessed the HDL-cargo (Cholesterol, ApoA-I, ApoA-II, ApoC-I, ApoC-III, ApoD, ApoE, ApoH, ApoJ, CRP, and SAA) …

Vpsl: Verifiable Privacy-Preserving Data Search For Cloud-Assisted Internet Of Things, Qiuyun Tong, Yinbin Miao, Ximeng Liu, Kim-Kwang Raymond Choo, Robert H. Deng

Research Collection School Of Computing and Information Systems

Cloud-assisted Internet of Things (IoT) is increasingly prevalent used in various fields, such as the healthcare system. While in such a scenario, sensitive data (e.g., personal electronic medical records) can be easily revealed, which incurs potential security challenges. Thus, Symmetric Searchable Encryption (SSE) has been extensively studied due to its capability of supporting efficient search on encrypted data. However, most SSE schemes require the data owner to share the complete key with query users and take malicious cloud servers out of consideration. Seeking to address these limitations, in this paper we propose a Verifiable Privacy-preserving data Search scheme with Limited …

Editing Out-Of-Domain Gan Inversion Via Differential Activations, Haorui Song, Yong Du, Tianyi Xiang, Junyu Dong, Jing Qin, Shengfeng He

Research Collection School Of Computing and Information Systems

Despite the demonstrated editing capacity in the latent space of a pretrained GAN model, inverting real-world images is stuck in a dilemma that the reconstruction cannot be faithful to the original input. The main reason for this is that the distributions between training and real-world data are misaligned, and because of that, it is unstable of GAN inversion for real image editing. In this paper, we propose a novel GAN prior based editing framework to tackle the out-of-domain inversion problem with a composition-decomposition paradigm. In particular, during the phase of composition, we introduce a differential activation module for detecting semantic …

This article explains how two AI systems have been incorporated into the everyday operations of two Singapore public healthcare nation-wide screening programs. The first example is embedded within the setting of a national level population health screening program for diabetes related eye diseases, targeting the rapidly increasing number of adults in the country with diabetes. In the second example, the AI assisted screening is done shortly after a person is admitted to one of the public hospitals to identify which inpatients—especially which elderly patients with complex conditions—have a high risk of being readmitted as an inpatient multiple times in the …

Qvip: An Ilp-Based Formal Verification Approach For Quantized Neural Networks, Yedi Zhang, Zhe Zhao, Guangke Chen, Fu Song, Min Zhang, Taolue Chen, Jun Sun

Research Collection School Of Computing and Information Systems

Deep learning has become a promising programming paradigm in software development, owing to its surprising performance in solving many challenging tasks. Deep neural networks (DNNs) are increasingly being deployed in practice, but are limited on resource-constrained devices owing to their demand for computational power. Quantization has emerged as a promising technique to reduce the size of DNNs with comparable accuracy as their floating-point numbered counterparts. The resulting quantized neural networks (QNNs) can be implemented energy-efficiently. Similar to their floating-point numbered counterparts, quality assurance techniques for QNNs, such as testing and formal verification, are essential but are currently less explored. In …

Guaranteeing Timed Opacity Using Parametric Timed Model Checking, Étienne André, Didier Lime, Dylan Marinho, Jun Sun

Research Collection School Of Computing and Information Systems

Information leakage can have dramatic consequences on systems security. Among harmful information leaks, the timing information leakage occurs whenever an attacker successfully deduces confidential internal information. In this work, we consider that the attacker has access (only) to the system execution time. We address the following timed opacity problem: given a timed system, a private location and a final location, synthesize the execution times from the initial location to the final location for which one cannot deduce whether the system went through the private location. We also consider the full timed opacity problem, asking whether the system is opaque for …

Pros: An Efficient Pattern-Driven Compressive Sensing Framework For Low-Power Biopotential-Based Wearable With On-Chip Intelligence, Nhat Pham, Hong Jia, Minh Tran, Tuan Dinh, Nam Bui, Young Kwon, Dong Ma, Phuc Nguyen, Cecilia Mascolo, Tam Vu

Research Collection School Of Computing and Information Systems

While the global healthcare market of wearable devices has been growing signi!cantly in recent years and is predicted to reach $60 billion by 2028, many important healthcare applications such as seizure monitoring, drowsiness detection, etc. have not been deployed due to the limited battery lifetime, slow response rate, and inadequate biosignal quality. This study proposes PROS, an e"cient pattern-driven compressive sensing framework for low-power biopotential-based wearables. PROS eliminates the conventional trade-o# between signal quality, response time, and power consumption by introducing tiny pattern recognition primitives and a pattern-driven compressive sensing technique that exploits the sparsity of biosignals. Specifically, we (i) …
