Articles

Background: A rebound in myopia progression following cessation of atropine eyedrops has been reported, yet there is limited data on the effects of stopping 0.01% atropine compared to placebo control. This study tested the hypothesis that there is minimal rebound myopia progression after cessation of 0.01% atropine eyedrops, compared to a placebo. Methods: Children with myopia (n = 153) were randomised to receive 0.01% atropine eyedrops or a placebo (2:1 ratio) daily at bedtime during the 2-year treatment phase of the study. In the third year (wash-out phase), all participants ceased eyedrop instillation. Participants underwent an eye examination every 6 …

Comparing Thin And Volume Regimes Of Analog Holograms For Wavefront Sensing, Emma Branigan, Andreas Zepp, Suzanne Martin, Matthew Sheehan, Szymon Gladysz, Kevin Murphy

Articles

Two analog holographic wavefront sensors, for measurement of defocus, have been fabricated as both thin and volume phase transmission holograms in a self-developing photopolymer. This represents the first reported direct comparison of hologram regimes when designed for wavefront sensing. An analysis of the effect of crosstalk in the presence of one other aberration mode (astigmatism X (0/90°), coma X (horizontal), and primary spherical aberration) was carried out with each version of the sensor. The performance of thin and volume analog holographic wavefront sensors was characterized under emulated conditions associated with moderate atmospheric turbulence.

Structure-Function Relationship Of Oat Flour Fractions When Blended With Wheat Flour: Instrumental And Nutritional Quality Characterization Of Resulting Breads, Mahmoud Said Rashed, Milica Pojić, Ciara Mcdonagh, Eimear Gallagher, Jesus M. Frias, Shivani Pathania

Articles

Abstract: The present work investigated the structure-function relationship of dry fractionated oat flour (DFOF) as a techno-functional ingredient using bread as a model system. Mechanically, DFOF fractions (F), that is, F1: <224 µm, F2: 250–280 µm, F3: 280–500 µm, F4: 500–600 µm, and whole oat flour (F5) were blended with white wheat flour at 10%, 30%, and 50% substitution levels for bread making. The blended flours, doughs, and bread samples were assessed for their techno-functional, nutritional, and structural characteristics. The results of Mixolab and the Rapid Visco Analyzer show that the 50% substituted F3 fraction exhibits the highest water absorption properties (69.53%), whereas the 50% F1 fraction exhibits the highest peak viscosity of the past slurry. Analysis of bread samples revealed a lower particle size of DFOF fractions and higher supplementation levels, increased β-glucan levels (0.13–1.29 g/100 bread (db), reduced fermentable monosaccharides, that is, glucose (1.44–0.33 g/100 g), and fructose (1.06–0.28 g/100 g). The effect of particle size surpassed the substitution level effect on bread volume reduction. The lowest hardness value for F1 is 10%, and the highest value for F2 is 50%. The total number of cells in the bread slice decreased from the control to the F4 fraction (50%). Multi-criteria analysis indicated that DFOF fractions produced breads with similar structure and higher nutritional value developed from white wheat flour. Practical Application: The use of mechanically fractionated oat flours fractions in white wheat flour breads can improve the nutritional profile without affecting the physical properties of the bread product. Based on the oat flour fractions, bakers and food processing companies can tailor the bread formulations for high β-glucan, high fiber, and low reduced sugar claims.

Myopia Progression Patterns Among Paediatric Patients In A Clinical Setting, Michael Moore, Gareth Lingham, Daniel Ian Flitcroft, James Loughman

Articles

Purpose

This retrospective analysis of electronic medical record (EMR) data investigated the natural history of myopic progression in children from optometric practices in Ireland.

Methods

The analysis was of myopic patients aged 7–17 with multiple visits and not prescribed myopia control treatment. Sex- and age-specific population centiles for annual myopic progression were derived by fitting a weighted cubic spline to empirical quantiles. These were compared to progression rates derived from control group data obtained from 17 randomised clinical trials (RCTs) for myopia. Linear mixed models (LMMs) were used to allow comparison of myopia progression rates against outputs from a predictive …

Essel, K. Healion, H. Hersbach, S. Madden, Jack Marshall, L. Mcconnell, I. Mensah, N. Scroxton, S. Thiesen, Peter Thorne

Articles

The majority of available climate data in global digital archives consist of data only from the 1940s or 1950s onwards, and many of these series have gaps and/or are available for only a subset of the variables which were actually observed. However, there exist billions of historical weather observations from the 1700s, 1800s, and early 1900s that are still in hard‐copy form and are at risk of being lost forever due to deterioration. An assessment of changes in climate extremes in several IPCC regions was not possible in IPCC AR6 WGI owing, in many cases, to the lack of available …

Data Justice In Education: Toward A Research Agenda, Luci Pangrazio, Glenn Auld, Julianne Lynch, Carly Sawatzki, Gavin Duffy, Shelley Hannigan, Jo O'Mara

Articles

Educational institutions increasingly rely on digital platforms to deliver content and learning, monitor attendance, communicate with stakeholders, and evaluate institutional performance. Despite the efficiency and accessibility gains they offer, digital platforms are powered by personal data which, through a process of datafication, can be used to track, monitor, and profile staff and students. The insights drawn from this data can be used to shape educational and professional futures. This article examines how datafication has become a social justice issue in education, discussing the implications for well-being, decision-making, governance, and power in education. Using Hintz and colleagues framework for data justice, …

An Image Processing Approach For Real-Time Safety Assessment Of Autonomous Drone Delivery, Assem A. Abdelhak, Dan Moss, Alan Hicks, Susan Mckeever

Articles

The aim of producing self-driving drones has driven many researchers to automate various drone driving functions, such as take-off, navigation, and landing. However, despite the emergence of delivery as one of the most important uses of autonomous drones, there is still no automatic way to verify the safety of the delivery stage. One of the primary steps in the delivery operation is to ensure that the dropping zone is a safe area on arrival and during the dropping process. This paper proposes an image-processing-based classification approach for the delivery drone dropping process at a predefined destination. It employs live streaming …

A Global Model-Agnostic Rule-Based Xai Method Based On Parameterized Event Primitives For Time Series Classifiers, Ephrem Tibebe Mekonnen, Luca Longo, Pierpaolo Dondio

Articles

Time series classification is a challenging research area where machine learning and deep learning techniques have shown remarkable performance. However, often, these are seen as black boxes due to their minimal interpretability. On the one hand, there is a plethora of eXplainable AI (XAI) methods designed to elucidate the functioning of models trained on image and tabular data. On the other hand, adapting these methods to explain deep learning-based time series classifiers may not be straightforward due to the temporal nature of time series data. This research proposes a novel global post-hoc explainable method for unearthing the key time steps …

Pricing Corporate Governance, Albert Choi

Articles

Scholars and practitioners have long theorized that by penalizing firms with unattractive governance features, the stock market incentivizes firms to adopt the optimal governance structure at their initial public offerings (IPOs). This theory, however, does not seem to match with practice. Not only do many IPO firms offer putatively suboptimal governance arrangements, such as staggered boards and dual-class structures, but these arrangements have been gaining popularity among IPO firms. This Article argues that the IPO market is unlikely to provide the necessary discipline to incentivize companies to adopt the optimal governance package. In particular, when the optimal governance package differs …

The Need For Energy Storage On Renewable Energy Generator Outputs To Lessen The Geeth Effect, I.E. Short-Term Variations Mainly Associated With Wind Turbine Active Power Output, Tony Kealy

Articles

Many studies investigating the short-term variations associated with the power output from wind turbine generators utilise simulated or modelled data in the analysis. This current study uses short-term empirical data downloaded directly from operational wind turbines via electrical power quality meters. The empirical data shows that the short-term variations (one-second or sub-one-second timeframe) occur continuously over most of the power output range. A novel name is proposed, the Geeth Effect, for this variability phenomenon. The Geeth Effect is measured using the coefficient of variation mathematical expression and is likely contributing to (i) lower-than-expected financial and environmental benefits associated with …

Renormalized Stress-Energy Tensor For Scalar Fields In Hartle-Hawking, Boulware, And Unruh States In The Reissner-Nordström Spacetime, Julio Arrechea, Cormac Breen, Adrian Ottewill, Peter Taylor

Articles

In this paper, we consider a quantum scalar field propagating on the Reissner-Nordström black hole spacetime. We compute the renormalized stress-energy tensor for the field in the Hartle-Hawking, Boulware and Unruh states. When the field is in the Hartle-Hawking state, we renormalize using the recently developed “extended coordinate” prescription. This method, which relies on Euclidean techniques, is very fast and accurate. Once, we have renormalized in the Hartle-Hawking state, we compute the stress-energy tensor in the Boulware and Unruh states by leveraging the fact that the difference between stress-energy tensors in different quantum states is already finite. We consider a …

Up To Code: Lessons Learned In Evaluating And Improving Legacy Irs, Frances Chang Andreu

Articles

Not all repositories are created under ideal circumstances, and inheriting an institutional repository can present challenges distinct from building one from scratch. Changes in institutional vision, policies, and priorities can lead to inconsistent content and limited metadata. Lack of documentation and loss of institutional memory can result in uncertainty about previous decisions. This case study examines the process of auditing a legacy institutional repository in order to ensure the content best reflects the institution’s current goals and policies.

States’ Duty Under The Federal Elections Clause And A Federal Right To Education, Evan Caminker

Articles

Fifty years ago, in San Antonio Independent School District v. Rodriguez, the Supreme Court failed to address one of the preeminent civil rights issues of our generation—substandard and inequitable public education—by holding that the federal Constitution does not protect a general right to education. The Court didn’t completely close the door on a narrower argument that the Constitution guarantees “an opportunity to acquire the basic minimal skills necessary for the enjoyment of the rights of speech and of full participation in the political process.” Both litigants and scholars have been trying ever since to push that door open, pressing …

Consent Searches And Underestimation Of Compliance: Robustness To Type Of Search, Consequences Of Search, And Demographic Sample, Roseanna Sommers, Vanessa K. Bohns

Articles

Most police searches today are authorized by citizens' consent, rather than probable cause or reasonable suspicion. The main constitutional limitation on so-called “consent searches” is the voluntariness test: whether a reasonable person would have felt free to refuse the officer's request to conduct the search. We investigate whether this legal inquiry is subject to a systematic bias whereby uninvolved decision-makers overstate the voluntariness of consent and underestimate the psychological pressure individuals feel to comply. We find evidence for a robust bias extending to requests, tasks, and populations that have not been examined previously. Across three pre-registered experiments, we approached participants …

The Federal Reserve's Mandates, David T. Zaring, Jeffery Y. Zhang

Articles

Solutions to systemic problems such as climate change and racial inequities have eluded policymakers for decades. In searching for creative solutions, some policymakers have recently thought about expanding the Federal Reserve’s core set of macroeconomic mandates to tackle these issues. But there are real questions about whether that can be done from a legal perspective and whether that should be done from a policy perspective.
