Background: Curative treatment for upper gastrointestinal (UGI) and hepatopancreaticobiliary (HPB) cancers, involves complex surgical resection often in combination with neoadjuvant/adjuvant chemo/chemoradiotherapy. With advancing survival rates, there is an emergent cohort of UGI and HPB cancer survivors with physical and nutritional deficits, resultant from both the cancer and its treatments. Therefore, rehabilitation to counteract these impairments is required to maximise health related quality of life (HRQOL) in survivorship. The initial feasibility of a multidisciplinary rehabilitation programme for UGI survivors was established in the Rehabilitation Strategies following Oesophago-gastric Cancer (ReStOre) feasibility study and pilot randomised controlled trial (RCT). ReStOre II will now …

Research outputs 2014 to 2021

Background: The importance of concurrent exercise order for improving endurance and resistance adaptations remains unclear, particularly when sessions are performed a few hours apart. We investigated the effects of concurrent training (in alternate orders, separated by ~3 hours) on endurance and resistance training adaptations, compared to resistance-only training. Materials and methods: Twenty-nine healthy, moderately-active men (mean ± SD; age 24.5 ± 4.7 y; body mass 74.9 ± 10.8 kg; height 179.7 ± 6.5 cm) performed either resistance-only training (RT, n = 9), or same-day concurrent training whereby high-intensity interval training was performed either 3 hours before (HIIT+RT, n = 10) …

Does Fibre-Fix Provided To People With Irritable Bowel Syndrome Who Are Consuming A Low Fodmap Diet Improve Their Gut Health, Gut Microbiome, Sleep And Mental Health? A Double-Blinded, Randomised Controlled Trial, Ran Yan, Mandy Murphy, Angela Genoni, Evania Marlow, Ian Dunican, Johnny Lo, Lesley Andrew, Amanda Devine, Claus T. Christophersen

Research outputs 2014 to 2021

Introduction:

A diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) is an effective way to reduce gut symptoms in people with irritable bowel syndrome (IBS). This diet reduces the intake of fermentable fibres, leading to changes of the gut microbiota and insufficient fermentation in the large bowel, resulting in reduced production of short-chain fatty acids (SCFAs), such as butyrate, which has unfavourable implications for gut health, sleep and mental health. This study will examine the effect of Fibre-fix, a supplement containing a mix of dietary fibres, on the human gut microbiome composition, fermentative capacity, sleep, quality of life …

Qualitative evidence that explores factors that influence adherence to treatment plans is limited.

Objective

This systematic review identified and synthesised the best available evidence on factors that influence adherence to treatment …

Which Dual-Band Infrared Indices Are Optimum For Identifying Aerosol Compositional Change Using Himawari-8 Data?, Miles Sowden, D Blake

Research outputs 2014 to 2021

Aerosol optical depth algorithms predominantly use the visible portion of the electromagnetic spectrum. However, quantifying sporadic dust events throughout the full 24-h period requires using continuous wavelengths such as infrared (IR). Identifying aerosols, using IR from geostationary data, has relied on subtraction indices rather than normalised differences. Limited attention has been given to determining which IR indices could be suitable for identifying aerosol compositional change. Suitable IR indices could potentially result in multi-spectral data from geostationary satellites, such as Himawari, being used to separate dust from other types of aerosols.

This study evaluated three index types: subtraction (brightness temperature difference …

A Novel Penalty-Based Wrapper Objective Function For Feature Selection In Big Data Using Cooperative Co-Evolution, A.N.M. Bazlur Rashid, Mohiuddin Ahmed, Leslie F. Sikos, Paul Haskell-Dowland

Research outputs 2014 to 2021

The rapid progress of modern technologies generates a massive amount of high-throughput data, called Big Data, which provides opportunities to find new insights using machine learning (ML) algorithms. Big Data consist of many features (also called attributes); however, not all these are necessary or relevant, and they may degrade the performance of ML algorithms. Feature selection (FS) is an essential preprocessing step to reduce the dimensionality of a dataset. Evolutionary algorithms (EAs) are widely used search algorithms for FS. Using classification accuracy as the objective function for FS, EAs, such as the cooperative co-evolutionary algorithm (CCEA), achieve higher accuracy, even …

Research outputs 2014 to 2021

Immunoglobulin G (IgG) is the most abundant serum antibody which structural characteristics and effector functions are modulated through the attachment of various sugar moieties called glycans. Composition of the IgG N-glycome changes with age of an individual and in different diseases. Variability of IgG glycosylation within a population is well studied and is known to be affected by both genetic and environmental factors. However, global inter-population differences in IgG glycosylation have never been properly addressed. Here we present population-specific N-glycosylation patterns of IgG, analyzed in 5 different populations totaling 10,482 IgG glycomes, and of IgG’s fragment crystallizable region (Fc), analyzed …

The Influence Of The Government On Corporate Environmental Reporting In China: An Authoritarian Capitalism Perspective, Hui Situ, Carol Tilt, Pi-Shen Seet

Research outputs 2014 to 2021

This study uses panel data to investigate the different roles of the Chinese government in influencing companies’ decision making about corporate environmental reporting (CER) via a two-stage process. The results show that the Chinese government appears to mainly influence the decision whether to disclose or not, but has limited influence on how much firms disclose. The results also show that the traditional model of authoritarian capitalism (under which state-owned enterprises [SOEs] are the major governance arrangement) is transforming into a new model. In the new model of authoritarian capitalism, the Chinese government uses newer, more sophisticated tools to manage both …

Soul Food: [Re]Framing The African-American Farming Crisis Using The Culture-Centered Approach, Andrew Laurence Carter, Adam Alexander

Faculty Research, Scholarly, and Creative Activity

Historically, African-American farmers faced a long and challenging struggle to own land and operate independently. In recent years, several factors, including unfair policy legislation, institutionalized racism, the mechanization of agriculture, and increases in agricultural technology have exacerbated land loss and decreases in farm ownership. Currently, African-American farmers are vastly underrepresented, comprising just 2% of the nation's farmers, 0.5% of farmland and 0.2% of total agricultural sales. As a site for inquiry, this topic has been examined across many academic sub-disciplines, however, the literature has not yet explored how the erasure of the African-American farmer influences the conversation about broader diet-related …

Sharper Bounds And Structural Results For Minimally Nonlinear 0-1 Matrices, Jesse Geneson, Shen Fu Tsai

Faculty Research, Scholarly, and Creative Activity

The extremal function ex(n, P) is the maximum possible number of ones in any 0-1 matrix with n rows and n columns that avoids P. A 0-1 matrix P is called minimally nonlinear if ex(n, P) = ω(n) but ex(n, P′) = O(n) for every P′ that is contained in P but not equal to P. Bounds on the number of ones and the number of columns in a minimally non-linear 0-1 matrix with k rows were found in (CrowdMath, 2018). In this paper, we improve the upper bound on the number of ones in a minimally nonlinear 0-1 matrix …

Tcad-Machine Learning Framework For Device Variation And Operating Temperature Analysis With Experimental Demonstration, Hiu Yung Wong, Ming Xiao, Boyan Wang, Yan Ka Chiu, Xiaodong Yan, Jiahui Ma, Kohei Sasaki, Han Wang, Yuhao Zhang

Faculty Research, Scholarly, and Creative Activity

This work, for the first time, experimentally demonstrates a TCAD-Machine Learning (TCAD-ML) framework to assist the analysis of device-to-device variation and operating (ambient) temperature without the need of physical quantities extraction. The ML algorithm used in this work is the Principal Component Analysis (PCA) followed by third order polynomial regression. After calibrated to limited 'expensive' experimental data, 'low cost' TCAD simulation is used to generate a large amount of device data to train the ML model. The ML was then used to identify the root cause of device variation and operating temperature from any given experimental current-voltage (I-V) characteristics. We …

Navigating Refugee Subjecthood: Cambodian American Education, Identity, And Resilience, Yvonne Y. Kwan

Faculty Research, Scholarly, and Creative Activity

To investigate trauma formation associated with the intricacy of Cambodian-specific experiences, this study examines how refugee identities and daily diasporic experiences shape the larger subject positions of subsequent generations—particularly through the concept of refugee subjecthood. Cambodia American students’ navigation of ethnic and racial identity reveals that in comparison to the available discursive narratives about their history (given to them through multicultural education), the younger generations’ is an inexact fit. To draw out the relationships between collective feelings and social experiences, this article addresses how Cambodian American students not only come into recognition about their positions as refugee subjects but also …

Ecg Biometric Authentication: A Comparative Analysis, Mohit Ingale, Renato Cordeiro, Siddartha Thentu, Younghee Park, Nima Karimian

Faculty Research, Scholarly, and Creative Activity

Robust authentication and identification methods become an indispensable urgent task to protect the integrity of the devices and the sensitive data. Passwords have provided access control and authentication, but have shown their inherent vulnerabilities. The speed and convenience factor are what makes biometrics the ideal authentication solution as they could have a low probability of circumvention. To overcome the limitations of the traditional biometric systems, electrocardiogram (ECG) has received the most attention from the biometrics community due to the highly individualized nature of the ECG signals and the fact that they are ubiquitous and difficult to counterfeit. However, one of …

Energy Filtering Effect At Source Contact On Ultra-Scaled Mosfets, Johan Saltin, Nguyen Cong Dao, Philip H.W. Leong, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

We postulate that in ultra-scaled Field Effect Transistors (FET), such as nanowires in sub-7nm technology, the source contact will act as an energy filter and increase the effective temperature of carriers arriving at the channel barrier. This is due to the absence of inelastic scattering in the short source-contact-to-channel region. As a result, the Sub-threshold Slope (SS) will increase substantially. In this paper, we verify this energy filtering effect through numerical calculations and Technology Computer-Aided-Design (TCAD) simulations calibrated to quantum solvers for electrostatics. It is found that SS degradation increases as the source metal workfunction increases. At 300K, in the …

Faculty Research, Scholarly, and Creative Activity

This study identifies how to screen for harmful alcohol use among gender minority (e.g., transgender and gender-expansive) people using brief screening methods and identifies which screening methods perform best among gender-expansive, transfeminine, and transmasculine subgroups, as screening recommendations are not currently available. Using 2018 Annual Questionnaire data from The PRIDE Study, area under the curve (AUC) values were compared to identify which screening methods (“4 or more” or “5 or more” drinks on one occasion in the past year, or one or more items from the Alcohol Use Disorders Identification Test [AUDIT]) best predicted (i) harmful alcohol use and (ii) …

Determination Of Demagnetizing Factors Using First-Order Reversal Curves And Ferromagnetic Resonance, K. S. Muster, R. Heindl

Faculty Research, Scholarly, and Creative Activity

We present a method to quantitatively analyze magnetizing or demagnetizing interactions in arrayed nano-magnets by combining first-order reversal curve (FORC) and ferromagnetic resonance (FMR) measurement data. We develop a function to predict the resulting FORC distribution given: (1) a Gaussian intrinsic distribution in terms of the internal field and (2) a mean interaction field proportional to the sample's magnetic moment. We then perform least-squares regression of our model on experimental FORC measurements of a nanowire array and of a thin film. Combining the obtained interaction field with an FMR fit result allows us to algebraically solve for the effective axial …

Research On Alcohol And Other Drug (Aod) Use Among Sexual Minority Women: A Global Scoping Review, Tonda L. Hughes, Cindy B. Veldhuis, Laurie A. Drabble, Sharon C. Wilsnack

Faculty Research, Scholarly, and Creative Activity

Until the 1980s, the limited research on alcohol and other drug (AOD) use among sexual minority women (SMW) focused on alcohol and used samples recruited from gay bars, resulting in inflated estimates of hazardous drinking. Over the past several decades the number of AOD studies with SMW has increased dramatically. To characterize this literature, we conducted a scoping review to answer the following questions: What do we know, and what are the gaps in research about AOD use among SMW? We searched multiple electronic databases (Medline [PubMed], CINAHL, PsycInfo, and Web of Science) for peer-reviewed research articles about AOD use …

The Relationship Between Workload, Performance And Fatigue In A Short-Haul Airline, Lucia Arsintescu, Ravi Chachad, Kevin B. Gregory, Jeffrey B. Mulligan, Erin E. Flynn-Evans

Faculty Research, Scholarly, and Creative Activity

The aim of this study was to determine the relationship between pilot workload, performance, subjective fatigue, sleep duration, number of sectors and flight duration during short-haul operations. Ninety pilots completed a NASA Task Load Index, Psychomotor Vigilance Task and a Samn-Perelli fatigue scale on top-of-descent of each flight and wore an activity monitor throughout the study. Weak, but significant, correlations were revealed between workload and all factors. Subjective fatigue, number of sectors and lapses were significant predictors of workload. Pilots reported higher workload when fatigue increased, the number of sectors were higher, and objective performance was worse.

Mitigating Fatigue On The Flight Deck: How Is Controlled Rest Used In Practice?, Cassie J. Hilditch, Lucia Arsintescu, Kevin B. Gregory, Erin E. Flynn-Evans
