The global Covid-19 pandemic has forced countries to impose strict lockdown restrictions and mandatory stay-at-home orders with varying impacts on individual’s health. Combining a data-driven machine learning paradigm and a statistical approach, our previous paper documented a U-shaped pattern in levels of self-perceived loneliness in both the UK and Greek populations during the first lockdown (17 April to 17 July 2020). The current paper aimed to test the robustness of these results by focusing on data from the first and second lockdown waves in the UK. We tested a) the impact of the chosen model on the identification of the …

Dataset Of Parent-Child Hyperscanning Functional Near-Infrared Spectroscopy Recordings, Andrea Bizzego, Giulio Gabrieli, Atiqah Azhari, Mengyu Lim, Gianluca Esposito

Research Outputs: 2025-Present

The term “hyperscanning” refers to the simultaneous recording of multiple individuals’ brain activity. As a methodology, hyperscanning allows the investigation of brain-to-brain synchrony. Despite being a promising technique, there is a limited number of publicly available functional Near-infrared Spectroscopy (fNIRS) hyperscanning recordings. In this paper, we report a dataset of fNIRS recordings from the prefrontal cortical (PFC) activity of 33 mother-child dyads and 29 father-child dyads. Data was recorded while the parent-child dyads participated in an experiment with two sessions: a passive video attention task and a free play session. Dyadic metadata, parental psychological traits, behavioural annotations of the play …

Biobanks are repositories of human biological samples and data. They are an important component of clinical research in many disease areas and often represent the first step toward innovative treatments. For biobanks to operate, researchers need human participants to give their samples and associated health data. In Ireland, research participants must provide their freely given informed consent for their samples and data to be taken and used for research purposes. Biobank staff are responsible for communicating the relevant information to participants prior to obtaining their consent, and this communication process is supported by the Participant Information Leaflets and Informed Consent …

Changes in the levels of circulating proteins are associated with Alzheimer’s disease (AD), whereas their pathogenic roles in AD are unclear. Here, we identified soluble ST2 (sST2), a decoy receptor of interleukin-33–ST2 signaling, as a new disease-causing factor in AD. Increased circulating sST2 level is associated with more severe pathological changes in female individuals with AD. Genome-wide association analysis and CRISPR–Cas9 genome editing identified rs1921622, a genetic variant in an enhancer element of IL1RL1, which downregulates gene and protein levels of sST2. Mendelian randomization analysis using genetic variants, including rs1921622, demonstrated that decreased sST2 levels lower AD …

Changes To The Gut Microbiome In Young Children Showing Early Behavioral Signs Of Autism, Jacquelyn Jones, Stacey N. Reinke, Mahsa Mousavi-Derazmahalleh, Debra J. Palmer, Claus T. Christophersen

Research outputs 2022 to 2026

The human gut microbiome has increasingly been associated with autism spectrum disorder (ASD), which is a neurological developmental disorder, characterized by impairments to social interaction. The ability of the gut microbiota to signal across the gut-brain-microbiota axis with metabolites, including short-chain fatty acids, impacts brain health and has been identified to play a role in the gastrointestinal and developmental symptoms affecting autistic children. The fecal microbiome of older children with ASD has repeatedly shown particular shifts in the bacterial and fungal microbial community, which are significantly different from age-matched neurotypical controls, but it is still unclear whether these characteristic shifts …

Tox And Detox: Are Teens' Smartphone Use And Non-Use Practices Fully Fungible?, Lelia Green, Debra Dudek, Lynne Cohen, Kjartan Ólafsson, Elisabeth Staksrud, Carmen Louise Jacques, Kelly Jaunzems

Research outputs 2022 to 2026

The public sphere includes a range of credible discourses asserting that a proportion of teenagers (“teens”) has an unhealthy dependence upon continuous connection with media devices, and especially smartphones. A review of media discourse (Jaunzems et al.) in Australia, and a critical review of public discourse in Australia and Belgium (Zaman et al.), reveal both positive and negative commentary around screentime. Despite the “emotionally laden, opposing views” expressed in the media, there appears to be a groundswell of concern around young people’s dependence upon digital devices (Zaman et al. 120). Concerns about ‘addiction’ to and dependency on digital media first …

A Global Model-Agnostic Xai Method For The Automatic Formation Of An Abstract Argumentation Framework And Its Objective Evaluation, Giulia Vilone, Luca Longo Jan 2022

A Global Model-Agnostic Xai Method For The Automatic Formation Of An Abstract Argumentation Framework And Its Objective Evaluation, Giulia Vilone, Luca Longo

Conference papers

Explainable Artificial Intelligence (XAI) aims to train data-driven, machine learning (ML) models possessing both high predictive accuracy and a high degree of explainability for humans. Comprehending and explaining the inferences of a model can be seen as a defeasible reasoning process which is expected to be non-monotonic meaning that a conclusion, linked to a set of premises, can be withdrawn when new information becomes available. Computational argumentation, a paradigm within Artificial Intelligence (AI), focuses on modeling defeasible reasoning. This research study explored a new way for the automatic formation of an argument-based representation of the inference process of a data-driven …

Quantitative Raman Analysis Of Carotenoid Protein Complexes In Aqueous Solution, Joy Udensi, Ekaterina Loskutova, James Loughman, Hugh Byrne

Datasets

Carotenoids are naturally abundant fat-soluble pigmented compounds, with dietary, antioxidant and vision protection advantages. The dietary carotenoids, Beta Carotene, Lutein and Zeaxanthin, complexed with in bovine serum albumin (BSA) in aqueous solution, were explored using Raman spectroscopy to differentiate and quantify their spectral signatures. UV visible absorption spectroscopy was employed to confirm the linearity of responses over the concentration range employed (0.05-1mg/ml) and, of the 4 source wavelengths, 785nm, 660nm, 532nm, 473nm, 532nm was chosen to provide the optimal response. After preprocessing to remove water and BSA contributions, and correct for self-absorption, a partial least squares model with R2 …

Robert Rauschenberg And Modernism’S (Other) Masculinity, Harry Trepess Jan 2022

Robert Rauschenberg And Modernism’S (Other) Masculinity, Harry Trepess

School of Law, Humanities and Social Sciences Theses

My project is concerned with understanding and identifying the possibility of self-censorship, within a queer theory framework, in Robert Rauschenberg's series of Combine works. Starting out by understanding ideas and theoretical concepts behind censorship (specifically Self-censorship, whether subliminal or acknowledged), through the work of previous scholars. Helping to differentiate the various forms censorship can take, to better establish a definition of what it means to self-censor. Which is vital for the ability of identifying the possible presence of this within Rauschenberg’s practice during the period he created the Combines. Previous iconographical readings, within a queer theory framework, should form a …

The 100 M Composite Ship?, Michael John Lowde, Henry George Arthur Peters, Ruadan Geraghty, Jasper Graham-Jones, Richard Pemberton, John Summerscales Jan 2022

The 100 M Composite Ship?, Michael John Lowde, Henry George Arthur Peters, Ruadan Geraghty, Jasper Graham-Jones, Richard Pemberton, John Summerscales

School of Engineering, Computing and Mathematics

Fibre-reinforced polymer (FRP) matrix composites are widely used in large marine struc-tures, and in wind turbines where blade lengths are now over 100 m. Composites are the material of choice for small vessels due to ease of manufacture, high hull girder stiffness, buckling resistance, corrosion resistance and underwater shock resistance. Ships over 100 m are still built using traditional steel and/or aluminium, but so far not FRP. Composite ship lengths have increased over the past 50 years, but fundamental technical challenges remain for the 100 m composite ship. Prelimi-nary studies suggest a possible 30% saving in structural weight, a 7–21% …

‘A Platform For Goodness, Not For Badness’: The Heuristics Of Hope In Patients' Evaluations Of Online Health Information, Alan Petersen, Allegra Schermuly, Alison Anderson

School of Law, Humanities and Social Sciences

Patient advocates and activists are increasingly relying on online health information that can assist them to manage their health condition. Yet once online, they will confront diverse information whose veracity and utility are difficult to determine. This article offers a sociological analysis of the practical methods, or heuristics, that patient advocates and activists use when making judgements about the credibility and utility of online information. Drawing on the findings from interviews with fifty Australian patient advocates and activists, it is argued that these individuals' use of these heuristics reflects their hopes that information can help them manage their condition which …

Zac: Efficient Zero-Knowledge Dynamic Universal Accumulator And Application To Zero-Knowledge Elementary Database, Hai Van Dang, Tran Viet Xuan Phuong, Thuc D. Nguyen, Thang Hoang

School of Engineering, Computing and Mathematics

—Zero-knowledge universal accumulator generates the succinct commitment to a set and produces the short (non) membership proof (universal) without leaking information about the set (zero-knowledge). In order to further support a generic set and zero-knowledge, existing techniques generally combine the zero-knowledge universal accumulator with other protocols, such as digital signatures and hashes to primes, which incur high overhead and may not be suitable for real-world use. It is desirable to commit a set of membership concealing the information with the optimal complexity. We devise ZAC, a new zero-knowledge Dynamic Universal Accumulator by taking the existing cryptographic primitives into account to …

A Novel Data-Driven Modeling Method For The Spatial-Temporal Correlated Complex Sea Clutter, Yanming Zhang, Lijun Jiang, Hong Tat Ewe Jan 2022

A Novel Data-Driven Modeling Method For The Spatial-Temporal Correlated Complex Sea Clutter, Yanming Zhang, Lijun Jiang, Hong Tat Ewe

Electrical and Computer Engineering Faculty Research & Creative Works

The sea clutter, referred to as the time-varying radar backscatter from the ocean surface, plays a significant role in marine radar development. The ocean's complex hydrodynamics cause it to exhibit non-Gaussian and nonstationary characteristics, which brings challenges in the sea clutter modeling, especially for establishing its spatial-temporal correlated and coherent model. In this article, a data-driven method based on the Koopman mode decomposition (KMD) is proposed for modeling spatial-temporal correlated complex sea clutter. The method decomposes the coherent sea clutter dynamic behavior in terms of Koopman modes and corresponding temporal patterns. Then, these spatiotemporal patterns are used to construct the …

Proportional Fair Clustered Federated Learning, Mohamed Nafea, Eugine Shin, Aylin Yener Jan 2022

Proportional Fair Clustered Federated Learning, Mohamed Nafea, Eugine Shin, Aylin Yener

Electrical and Computer Engineering Faculty Research & Creative Works

This paper studies federated learning (FL) with non-identical data generating distributions and under the notion of proportional fairness. Users are partitioned into disjoint clusters based on their data distributions, and a distinct model is learnt for each cluster. Different than previous work that considered clustering to optimize personalized learning performance, here clustering is inspected under the disparate impact doctrine which requires that protected classes (e.g., those of certain race or gender) have representations in every cluster that are approximately equal to their representation in the overall set of users. A family of iterative algorithms that balance the learning performance and …

Simulation Study Of A Probabilistic Measurement Terminator For Cloud Radar Systems Using Cloudsat Data, Jakob Delong, Joel T. Johnson Jan 2022

Simulation Study Of A Probabilistic Measurement Terminator For Cloud Radar Systems Using Cloudsat Data, Jakob Delong, Joel T. Johnson

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a novel probabilistic method that is used to identify low-SNR measurements in a cloud profiling radar application and terminate them before completion to save resources. The method uses a statistical model to predict the final SNR level of a measurement in progress and terminate it if it falls below a specified threshold at a specified level of confidence. The method is applied in a simulation study in which radar backscattered power profiles are obtained from CloudSat radar data, and is shown to achieve favorable performance.

Religious Affiliation’S Association With Suicidality Across Sexual Orientations And Gender Identities, W. Justin Dyer, Michael A. Goodman

Faculty Publications

The objective was to replicate and extend earlier findings examining the intersection of sexual orientation and religious affiliation predicting suicidality. Current analyses used updated data and extended prior work by examining how affiliation relates to suicidality for transgender individuals. Data were collected in 2021 from 46,562 adolescents and were representative of Utah adolescents in grades 8, 10, and 12. In regressions, affiliation predicted suicidality and subsequent models added demographics, family functioning, drug use, feeling socially integrated, and interaction terms between sexual orientation, gender identity, and affiliation. In baseline models, affiliation was related to fewer mental health difficulties. When including drug …

Religiosity From Age 12 To 20: Stability, Change, And Bidirectional Effects Of Attendance, Prayer, And Salience, W. Justin Dyer, Sam A. Hardy, Michael Goodman

Faculty Publications

Religiosity is a protective factor for adolescents, though research has indicated religiosity declines across adolescence. However, little research has examined how various dimensions of religiosity may change across time. With yearly data from a sample of 489 participants, the current study examined rank-order and mean level changes in religiosity from early adolescence (12 years-old) into late adolescence/emerging adulthood (20 years-old). Three dimensions of religiosity were examined, public religious practices (religious service attendance), private religious practices (prayer), and religious salience. Using cross-lagged models, reciprocal relationships between these dimensions were examined. There was significant rank-order stability, though stability was highest for attendance. …

“It Only Hurts When I Laugh”: Tolerating Bullying Humour In Order To Belong At Work, Barbara Plester, Tim Bentley, Emily Brewer Jan 2022

“It Only Hurts When I Laugh”: Tolerating Bullying Humour In Order To Belong At Work, Barbara Plester, Tim Bentley, Emily Brewer

Research outputs 2022 to 2026

Our study examines the impacts on workers when organisational humour is repeated, sustained, dominating, and potentially harmful, and thus can be considered to be bullying. In an ethnographic study of an idiosyncratic New Zealand IT company, we observed humour that was sexualised, dominating, and perpetrated by the most powerful organizational members. We argue that the compelling need for belonging in this extreme organizational culture influenced workers to accept bullying humour as just a joke and therefore acceptable and harmless even when it contravened societal workplace norms. Our contribution is in identifying and extending the significant theoretical relationship between workplace humour …

Improving Virtual Synchronous Generator Control In Microgrids Using Fuzzy Logic Control, Oroghene Oboreh-Snapps, Rui Bo, Buxin She, Fangxing Fran Li, Hantao Cui Jan 2022

Improving Virtual Synchronous Generator Control In Microgrids Using Fuzzy Logic Control, Oroghene Oboreh-Snapps, Rui Bo, Buxin She, Fangxing Fran Li, Hantao Cui

Electrical and Computer Engineering Faculty Research & Creative Works

Virtual synchronous generators (VSG) are designed to mimic the inertia and damping characteristics of synchronous generators (SG), which can improve the frequency response of a microgrid. Unlike synchronous generators whose inertia and damping are restricted by the physical characteristics of the SG, VSG parameters can be more flexibly controlled to adapt to different disturbances. This paper therefore proposes a fuzzy logic controller designed to adaptively set the parameters of the VSG during a frequency event to ensure an improved frequency nadir and rate of change of frequency (ROCOF) response. The proposed control method is implemented and tested on the power …

Practical Fixture Design For Passive Intermodulation Tests For Flexible Metallic Contacts, Shengxuan Xia, Yuchu He, Yansheng Wang, Hanfeng Wang, George Mankaruse, Danny Chan, Haicheng Zhou, Warren Lee, Nicholas Mcdonnell, Chulsoon Hwang

Electrical and Computer Engineering Faculty Research & Creative Works

Passive intermodulation (PIM) commonly exists in non-ideal metallic contacts. Since PIM typically represents an extremely low level of nonlinearity, it has not drawn enough attention over the years except for extremely high-power applications such as base stations. However, in recent years, the study on PIM has become essential in universally used consumer electronics design because of the higher requirement on the radio frequency (RF) sensitivity of wireless communications. The metal contacts caused PIM can create the sideband spectrum to interfere with the receiving band in the frequency divide duplex (FDD) mode. Therefore, the study on PIM for the frequently used …

3d Printed Multilayer Microwave Absorber, Wei Zhang, Rui Mi, Victor Khilkevich

Electrical and Computer Engineering Faculty Research & Creative Works

This paper explores the possibility to create 3D printed multilayer electromagnetic absorbers. The proposed design is similar to the thin-film filters used in optics and consists of interleaving high and low permittivity layers. Based on transmission line theory, the multilayer absorber can be designed in a circuit simulator. Analytical equations, circuit simulations, and measurements are used to analyze and validate the designed absorber. Multilayer absorbers based on 3D printed material can be an inexpensive option for engineering usage with great design flexibility and fast fabrication.
