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.

Inclusion4eu: Towards A Framework Of Inclusive Software Design Processes And Practices, Damian Gordon, Andrea Curley, Emma Murphy, John Gilligan, Anna Becevel, Dympna O'Sullivan

Articles

This research is based on a trans-European research project aimed at enhancing software design and engineering practices to promote inclusivity, involving stakeholders from academia, industry, and disability advocacy services. To explore the nature and meaning of inclusion, a number of different approaches to inclusion are outlined, including models of equitable design (Accessible Design, Inclusive Design, Universal Design, and Design for All), User Design processes (Co-Production, Co-Creation, User-Centred Design, Co-Design, and Participatory Design), and Software Engineering Methodologies (Linear, Spiral, and Agile). These three categories of models are combined to form a three-dimensional environment in which software development projects can be mapped …

Designing Self-Management For And With Persons Living With Dementia Osullivan, Dympna, Dympna O'Sullivan, Michael Wilson, Damon Berry, Orla Moran, Siobhan O,Neill, Ciaran Nugent, Jonathan Turner, Julie Doyle

Articles

Promoting high quality of life for persons living with dementia has emerged as a central goal in global public health agendas. The emphasis has shifted from extending life to actively enhancing overall well-being by postponing or preventing additional disability. This represents a departure from traditional medical perspectives on dementia to a more socially-oriented approach, placing a strong focus on wellbeing.

In parallel, the concept of self-management for people with living dementia has emerged, where this is a person-centred approach in which the individual is empowered and has ownership over the management of their life and condition. Practice recommendations for person-centered …

Knowledge Held Hostage: What The British Library Ransomware Attack Can Teach Us, Moira Fiscus

Articles

The British Library hack and its response serve as a clear example of the vulnerability of institutions of higher learning to such attacks and the importance of maintaining an open dialogue with the public during recovery. This open dialogue is currently lacking as universities attempt to move on and cover up these attacks quickly. This paper aims to start the conversation by providing three examples of institutions that went through a hack that left their services down for a significant period, how it affected those they serve, how these institutions responded, and what information was made public.

Schrodinger's Dissent: The Hybrid Authority Of A Dissenting Opinion, Christina Frohock

Articles

A dissenting opinion is the Schrodinger's cat of authorities: both the law and not the law simultaneously. Courts and scholars often clarify that a dissenting opinion is not binding. Outside the universe of precedent, that authority defies easy description. Emerging from the pen of a judge wearing a black robe and acting in an official capacity, a dissenting opinion exhibits the form of the law. Yet, beneath that lofty sheen, a dissent exhibits the substance of commentary. A dissenting judge writes to undercut the law, providing a case law coda. This Article describes the traditional categories of authority, primary and …

Systemic Regulation Of Artificial Intelligence, Yonathan Arbel, Matthew Tokson, Albert Lin

Articles

Today's artificial intelligence ("AI") systems exhibit increasing capabilities across a remarkable variety of tasks. The rapid growth in AI ability has caught the attention of policymakers, parliaments, and the United Nations. These entities are increasingly looking towards regulating AI, not only in its particular applications, but as a technology. Yet legal scholarship has thus far offered little to this new and critical regulatory conversation, which has instead been dominated by computer scientists and technologists.

This Article begins the project of assessing AI's broader risks and law's role in addressing them. These risks are wide ranging -they span harms to vulnerable …

Microglial Piezo1 Mechanosensitive Channel As A Therapeutic Target In Alzheimer's Disease, Erol D Ikiz, Erin R Hascup, Chilman Bae, Kevin N Hascup

Articles

Microglia are the resident macrophages of the central nervous system (CNS) that control brain development, maintain neural environments, respond to injuries, and regulate neuroinflammation. Despite their significant impact on various physiological and pathological processes across mammalian biology, there remains a notable gap in our understanding of how microglia perceive and transmit mechanical signals in both normal and diseased states. Recent studies have revealed that microglia possess the ability to detect changes in the mechanical properties of their environment, such as alterations in stiffness or pressure. These changes may occur during development, aging, or in pathological conditions such as trauma or …

Investigation Of The Uv-Resistance Of Photopolymerisable Glass For Space Applications, Luca Sorridente, Tatsiana Mikulchyk, Izabela Naydenova, Kevin Murphy

Articles

The progress of space based scientific research leads to an increasing demand for more efficient and less bulky instruments. Conventional refractive elements make up a critical part of many optical instruments launched into space; however, they can be bulky and heavy. Holographic optical elements are an efficient alternative to replace the conventional optical elements as they are lightweight and can be miniaturized. Current materials typically used for volume holographic optical elements are not robust enough for use in space environment. Recently a promising photopolymerisable glass has been developed using a sol-gel technique, which can provide dry layers suitable for holographic …

Photopolymer Material Durability And Safety In Holographic Diffusers For Visual Applications, Matthew Hellis, Alan Casey, Edoardo Splendi, Suzanne Martin, Matthew Sheehan, Kevin Murphy

Articles

This study introduces novel holographic diffuser applications employing acrylamide- or diacetone acrylamide-based photopolymers, patterned within the volume on a micron scale by a single-beam holographic recording process. These diffusers have previously been presented as potential treatments for amblyopia and diplopia. This work has now been extended to spectrometric analysis to determine their properties under broadband light. Diffusive elements with higher diffusion efficiencies exhibited a marginal reduction (< 5%) in diffusion efficiency across most of the visible spectrum. Given the intended application of these holographic diffusers, cytotoxicity assessments were also performed. This is significant as there is a difference in toxicity between the crystalline acrylamide (classified as a category 3 material) and diacetone acrylamide (classified as a category 4 material). The findings indicated substantially lower toxicity in holograms produced with diacetone acrylamide-based photopolymer. The accelerated ageing of both formulations of holographic diffusers indicated that the acrylamide-based holographic diffusers did not reduce efficacy in the 292 days of ageing. The diacetone acrylamide-based holographic diffusers exhibited reduced efficacy by day 182. Despite this, both formulations have been shown to perform for prolonged periods as the treatment modality would require. These results emphasise that holographic diffusers exhibit minimal spectral impact, and longevity on the scale of treatment regimes which are crucial considerations for their prospective use case as treatments for amblyopia and diplopia.

Digital Barter Taxes: A Legal Defense, Young Ran (Christine) Kim, Darien Shanske

This short essay, aimed at state legislators, defends digital barter taxes from the most common legal objections.

The Broader Lessons Of Privacy Law, Salome Viljoen

Articles

This Article explores the trend of privacy—and what kind of techno-social or legal effect ought to count as a “privacy harm”—expanding to encompass a growing set of social factors. This big-tent approach to privacy has several virtues. However, it also comes with a few costs. While others have explored the conceptual and doctrinal tradeoffs that an expansive approach to privacy may entail, this Article focuses on a secondary effect the trend toward expansiveness has had on the relationship between privacy scholarship and legal scholarship more broadly. This Article suggests that the internal expansiveness of privacy means that insights developed within …

The Myth Of Slavery Abolition, Jocelyn Getgen Kestenbaum

Articles

In many countries today, slavery and the slave trade continue with impunity. International human rights law prohibits both abuses, but states are rarely held accountable and people who are enslaved or slave traded rarely receive redress. This Article offers a novel account of why international human rights law advocacy neglects slavery and the slave trade. Specifically, this Article demonstrates that the abolition of the Transatlantic and East African slave trades was achieved through a legal framework that marginalized the human rights of enslaved persons while consolidating empire. In the wake of World War II, prohibitions on slavery and the slave …

All Roads Lead To Rome: Combating Impunity For Perpetration Of Slave Trade And Slavery Crimes, Jocelyn Getgen Kestenbaum

Articles

The Republic of Sierra Leone has proposed amendments to the Rome Statute of the International Criminal Court (ICC) to include, inter alia, provisions for the slave trade as a crime against humanity and has recommended that the General Assembly include the slave trade as an enumerated crime in the Draft articles on Prevention and Punishment of Crimes Against Humanity (CAH) (Draft articles). This declaration came nearly five years after Cardozo’s Benjamin B Ferencz Human Rights and Atrocity Prevention Clinic, on behalf of slavery crimes expert Patricia Viseur Sellers, sent commentaries to the United Nations International Law Commission (ILC) to revise …

Water Management And Conservation In India Fostering Water Justice: Arguing For Adopting Just Sustainability In Water Governance, Gayathri D Naik Dr, Sanjay Shenoi P

Articles

The water sector is characterised by everyday water injustices where factors like social discrimination, economic disparities, and political preferences influence the determination of water resource access, allocation, and management. The increasing anthropogenic impacts on water resources and consequent threats to sustainability add to the water injustices, often impacting the poorer, socially downtrodden communities that bear the brunt of water scarcity and cannot afford alternatives. The current water governance patterns, prioritising equality over equity, fail to address the issues of water injustices created by social, political, and economic factors in water management and sideline the ecological impacts on water resources. Moving …

Modeling Redistribution Of Nanozeolites In Holographic Recording, Dana Mackey, Jack Lyons Dr, Izabela Naydenova

Articles

Zeolite doped photopolymers have been studied experimentally due to their potential application in the develop- ment of optical sensors. It has been shown that dopant redistribution can be achieved by holographic recording and has a direct influence on the sensitivity of the recorded grating. To achieve better theoretical understanding of these processes, this paper proposes an extended photopolymerization-diffusion mathematical model for describing the dynamics of nanozeolite redistribution during recording in an acrylamide-based photopolymer. Using numerical simulations of this model, we investigate how recording conditions, dopant transport parameters, and initial load affect the refractive index modulation of the resulting photonic structure.

Holographic Multiplexing In A Photopolymerisable Hybrid Sol-Gel, Pamela Stoeva, Tatsiana Mikulchyk, Izabela Naydenova, Kevin Murphy

Articles

Holographic multiplexing techniques enhance functionality and information storage by leveraging the inherent selectivity of holograms. This is crucial for advancing holographic sensors, which excel in simultaneously detecting multiple parameters from a single input signal. This study explores the potential of the recent photopolymerisable hybrid sol-gel (PHSG) material for application in Space sensing systems through the investigation of its holographic angular multiplexing capabilities. For the first time, to the best of our knowledge, we report the successful recording of up to five angularly multiplexed gratings with diffraction efficiencies (DE) ≥ 15% in 187 ± 18 µm PHSG layers. A 3 mW/cm2 …

Beyond The Human: Crossovers For An Onto-Epistemological Bifurcation, Ester Toribio-Roura

Articles

Building upon recent studies in new materialisms and feminist critical posthumanism with a focus on human and more-than-human relationships, this paper examines how the posthuman paradigm, by postulating the queering of identit(ies) via entanglement with the more-than-human (including technology), and by offering a critical examination of diverse modes of existence within a broader ecological context, can foster more inclusive and ethically sound ways of being in the world. Although posthumanism encompasses a wide range of perspectives and theories, including transhumanism, at its core, it challenges traditional notions of humanism, blurring the boundaries between what is human and what is more-than-human, …

Early Age Assessment Of A New Course Of Irish Fly Ash As A Cement Replacement, Niall Holmes Dr., Nikki Shaji, Mark Tyrer

Articles

This paper explores the potential of a new source of fly ash, deposited on the site of a coalfired power plant in Ireland dating from 1985 to 1995, as a cement replacement material. A series of X-ray diffraction (XRD) analyses on binder samples with cement replacement levels of 0, 10, 25 and 35% was undertaken to determine the fly ash’s mineralogical composition and to determine its suitability as a supplemental cementitious material (SCM). The XRD results reveal a unique mineral composition with promising characteristics for enhancing the strength and durability of concrete. The experimental results were used to calibrate a …

Dual-Systems And Fuzzy-Trace Theory Predictions Of Covid-19 Risk Taking In Young Adults, Sarah M. Edelson, Valerie F. Reyna, Bridget B. Hayes, David M. N. Garavito

Articles

Risk-reduction behaviors are the first line of defense in viral epidemics. Choosing to not engage in risk-reduction behaviors produced millions of preventable deaths from COVID-19. Understanding why this happens and how to predict it is important for theory development and public policy. We took four approaches to this problem: experimentally varying theory-driven predictors (social rewards, transmission risk, and mandatory/voluntary regulations) in choice scenarios, further probing choices in specific scenarios predicted to elicit risk taking, conducting hierarchical regressions with demographic and theory-driven predictors for both scenario types, and conducting corresponding regressions for self-reported protective behaviors. The sample consisted of 247 young …

A Central Limit Theorem For The Number Of Excursion Set Components Of Gaussian Fields, Dmitry Beliaev, Michael Mcauley, Stephen Muirhead

Articles

For a smooth stationary Gaussian field f on R^d and level ℓ ∈ R, we consider the number of connected components of the excursion set {f ≥ ℓ} (or level set {f = ℓ}) contained in large domains. The mean of this quantity is known to scale like the volume of the domain under general assumptions on the field. We prove that, assuming sufficient decay of correlations (e.g. the Bargmann-Fock field), a central limit theorem holds with volume-order scaling. Previously such a result had only been established for ‘additive’ geometric functionals of the excursion/level sets (e.g. the volume or …

Explainable Machine Learning For The Regulatory Environment: A Case Study In Micro-Droplet Printing, Elaine Harris, Darragh F. Ryan, Gerard M. O'Connor

Articles

Micro-droplet printing remains an invaluable tool for the additive manufacturing industry due to its versatility, efficiency and cost-effectiveness. The design and deployment of a disposable micro-droplet dispenser seeks to facilitate a quick and easy way to alternate between different printing materials (such as ink, metals, bio-materials, pharmaceuticals, etc.) without the need for thorough cleaning or separate delivery systems. While this works well in principle, in practice achieving consistent performance between dispensers can prove challenging. This paper aims to tackle this issue through the use of Machine Learning (ML) in order to (1) build a model that predicts dispenser performance from …

Rethinking Taxing Excess Profits, Reuven S. Avi-Yonah, Tamir Shanan

Articles

This article discusses the application of excess profit taxes (EPTs, also referred to as windfall taxes) that have gained renewed interest and popularity over the past several years. The revival of these windfall taxes gained renewed interest following the COVID-19 outbreak, which led to a sharp price increase in corporate revenues of medical equipment and within pharmaceutical industries. However, the revival of such taxes was also used following the recent rise in energy prices mainly in Europe, leading to a sharp increase in corporate revenues of energy corporations and the recent surge in borrowing interest rates that was not accompanied …

A History Of Corporate Law Federalism In The Twentieth Century, William Wilson Bratton

Articles

This Article describes the emergence of corporate law federalism across a long twentieth century. The period begins with New Jersey's successful initiation of charter competition in 1888 and ends with the enactment of the Sarbanes-Oxley Act in 2002. The federalism in question describes the interrelation of state and federal regulation of corporate internal affairs. This Article takes a positive approach, pursuing no normative bottom line. It makes six observations: (1) the federalism describes a division of subject matter, with internal affairs regulated by the states and securities issuance and trading regulated by the federal government; (2) the federalism is an …

Big Data Searches And The Future Of Criminal Procedure, Mary Fan

Articles

This Article proceeds in three parts. Part I illuminates the nostalgic Luddism that influences Fourth Amendment jurisprudence and the challenges posed by evolving technologies to this dominant lens. This Part explains the operation of geofence and keyword warrants and how their power to crack cold cases by unidentified perpetrators both tempt and terrify. The confusion in the courts over the constitutionality of geofence and keyword warrants is emblematic of the larger challenges of the Romantic Luddism in Fourth Amendment originalism that has grown in influence over the decades.

Part II frames and theorizes the concepts of collateral impact and collateral …

Liability Rules For Automated Vehicle: Definitions And Details, William H. Widen, Phillip Koopman

Articles

This paper explains how the law ought to assign liability for automated vehicle accidents by providing an example of a proposed statute. We advocate for the creation of the legal fiction of a "Computer Driver," which can have negligence liability, anytime a court or jury determines that the Computer Driver's behavior failed to imitate or exceed the level of care we would expect of an attentive and unimpaired Human Driver in similar circumstances. We then use this concept to explain how to determine contributory negligence and comparative fault when control of a vehicle is transferred from a Computer Driver to …

Taxing The Metaverse, Young Ran (Christine) Kim

Articles

The buzz surrounding the Metaverse has been growing steadily for the past couple of years, but the tax implications of this novel ecosystem remain fuzzy to most tax scholars. Such uncertainty is concerning, given the potential and momentum of this emerging technology. Although the Metaverse evolved from online video games focused only on user consumption, it now allows users to produce income and accumulate wealth entirely within the Metaverse. Current law seems to defer taxation of such until a realization or cash-out event. This Article challenges this approach and offers novel arguments justifying Metaverse taxation. Because economic activity within the …
