Combined Experimental And Modeling Analysis For Thedevelopment Of Optical Materials Suitable To Enhance Theimplementation Of Plasmonic-Enhanced Luminescent Down-Shifting Solutions On Existing Silicon-Based Photovoltaic Devices, James Walshe, Mihaela Girtan, Sarah Mccormack, John Doran, George Amarandei

Articles

The development of highly efficient solar collectors requires modulating the light interactions with the semiconducting materials. Incorporating luminescent species and metal nanoparticles within a semitransparent polymeric material (e.g., polymethyl methacrylate (PMMA)) leads to the formation of a plasmon-enhanced luminescent down-shifting (PLDS) layer, which offers a retrofittable approach toward expanding the wavelength range over which the conversion process can effectively occur. Adding antireflection coatings (ARCs) further controls the spectral response. However, with each additional component comes additional loss pathways. In this study, the losses related to light interactions with the PMMA and the ARCs have been investigated theoretically using a transfer …

Substance Use Disorder Discrimination And The Cares Act: Using Disability Law To Inform Part 2 Rulemaking, Kelly K. Dineen, Elizabeth Pendo

Articles

Substance use disorder (SUD) is a chronic health condition—like people with other chronic health conditions, people with SUDs experience periods of remission and periods of exacerbation or recurrence. Unlike people with most other chronic conditions, people with SUDs may be more likely to garner law enforcement attention than medical attention during a recurrence. They are also chronically disadvantaged by pervasive social stigma, discrimination, and structural inequities. The COVID-19 pandemic has had devastating consequences for people with SUDs, who are at higher risk for both contracting the SARS-CoV-19 virus and experiencing poorer outcomes. Meanwhile, there are early indications that pandemic conditions …

Homes, History, And Shadows: Select Criminal Law And Procedure Cases From The Supreme Court’S 2020-21 Term, Eve Brensike Primus, Lily Sawyer-Kaplan

Articles

The death of Justice Ruth Bader Ginsburg in September 2020 and the appointment of Justice Amy Coney Barrett to replace her solidified a 6-3 majority on the Court for Republican appointees and is already affecting how the Court approaches and decides its criminal law and procedure cases. Justice Ginsburg, a strong advocate for equality and fair treatment, generally construed criminal statutes narrowly and stressed the importance of defendants’ procedural rights. Justice Barrett is an originalist who will look to history to seek answers on the scope of criminal procedure amendments. The combined appointments of Justice Gorsuch and Justice Barrett mean …

Certain Effects Of Random Taxes, James R. Hines Jr., Michael J. Keen

Articles

This paper explores the implications of tax rate randomness, identifying circumstances in which revenue-neutral rate variability increases profitability, economic activity, and the efficiency of resource allocation. Furthermore, with heterogeneous taxpayers, tax rate variability is shown to perform an efficiency-enhancing screening function, imposing heavier expected tax burdens on less responsive taxpayers. And while efficient tax randomness enables governments to reduce average costs of taxation, it necessarily increases the marginal cost of taxation over some ranges of expected revenue, so may reduce efficient levels of government spending.

How Much Can Potential Jurors Tell Us About Liability For Medical Artificial Intelligence?, W. Nicholson Price Ii, Sara Gerke, I. Glenn Cohen

Articles

Artificial intelligence (AI) is rapidly entering medical practice, whether for risk prediction, diagnosis, or treatment recommendation. But a persistent question keeps arising: What happens when things go wrong? When patients are injured, and AI was involved, who will be liable and how? Liability is likely to influence the behavior of physicians who decide whether to follow AI advice, hospitals that implement AI tools for physician use, and developers who create those tools in the first place. If physicians are shielded from liability (typically medical malpractice liability) when they use AI tools, even if patient injury results, they are more likely …

Recollections Refreshed And Recorded, Leonard M. Niehoff

Articles

Witnesses forget stuff. When they do, the evidence rules give us two tools to help solve the problem. Lawyers call one "refreshed recollection" and the other "past recollection recorded," labels just similar enough to guarantee confusion. Nevertheless, these principles get at very different things and are well worth the effort necessary to distinguish and understand them.

So how do we get there?

Beyond Plea Bargaining: A Theory Of Criminal Settlement, Richard Lorren Jolly, J.J. Prescott

Articles

Settlement is a term rarely used in criminal law. Instead, people speak almost exclusively of plea bargaining—i.e., enforceable agreements in which a defendant promises to plead guilty in exchange for a prosecutor’s promise to seek leniency in charging or at sentencing. But a traditional plea agreement is just the most visible instance of a much broader class of possible criminal settlement agreements. In terms of their fundamentals, criminal settlements are indistinguishable from their civil counterparts: through either an atomized or comprehensive bargain, parties exchange what they have for what they want, advancing their respective interests in cost minimization, risk mitigation, …

Is There A Delaware Effect For Controlled Firms?, Edward Fox

Articles

The impact of Delaware incorporation on firm value remains a central question in corporate law. Despite the difficulty scholars have had in agreeing on an answer to this question, there is a consensus that Delaware has long enjoyed stable and important advantages in the expertise of its judiciary and its extensive case law. These advantages are believed to be particularly important for firms with a controlling shareholder. This Article attempts to empirically measure the effect of Delaware incorporation on these controlled firms and thus helps us understand the market value of Delaware’s judiciary and case law. It finds, surprisingly, that …

Clearing Opacity Through Machine Learning, W. Nicholson Price Ii, Arti K. Rai

Articles

Artificial intelligence and machine learning represent powerful tools in many fields, ranging from criminal justice to human biology to climate change. Part of the power of these tools arises from their ability to make predictions and glean useful information about complex real-world systems without the need to understand the workings of those systems.

Geocoding Cryptosporidiosis Cases In Ireland (2008–2017)—Development Of A Reliable, Reproducible, Multiphase Geocoding Methodology, Lisa Domegan, Patricia Garvey, Paul Mckeown, Howard Johnson, Paul Hynds, Jean O'Dwyer, Coilín Óhaiseadha

Articles

Background: Geocoding (the process of converting a text address into spatial data) quality may affect geospatial epidemiological study findings. No national standards for best geocoding practice exist in Ireland. Irish postcodes (Eircodes) are not routinely recorded for infectious disease notifications and > 35% of dwellings have non-unique addresses. This may result in incomplete geocoding and introduce systematic errors into studies.

Aims: This study aimed to develop a reliable and reproducible methodology to geocode cryptosporidiosis notifications to fine-resolution spatial units (Census 2016 Small Areas), to enhance data validity and completeness, thus improving geospatial epidemiological studies.

Methods: A protocol was devised to utilise …

Franchisor Power As Employment Control, Andrew Elmore, Kati L. Griffith

Articles

Labor and employment laws are systematically underenforced in low-wage, franchised workplaces. Union contracts, and the benefits and protections they provide, are nonexistent. The Fight for Fifteen movement has brought attention to the low wages, systemic violations of workers' rights, and lack of collective representation in fast-food franchises. Given that franchisees can be judgment-proof and cannot set industry standards, the deterrence, remedial, and collective bargaining goals of labor and employment laws can depend on holding the franchisor (the brand) responsible under the joint employer doctrine. In a series of cases, however, a dominant approach has emerged that essentially foreclosed the possibility …

An Extracellular Lipase From Amycolatopsis Mediterannei Is A Cutinase With Plastic Degrading Activity, Yeqi Tan, Gary T. Henehan, Gemma K. Kinsella, Barry J. Ryan

Articles

An extracellular lipase from Amycolatopsis mediteranei (AML) with potential applications in process biotechnology was recently cloned and examined in this laboratory. In the present study, the 3D structure of AML was elucidated by comparative modelling. AML lacked the ‘lid’ structure observed in most true lipases and shared similarities with plastic degrading enzymes. Modelling and substrate specificity studies showed that AML was a cutinase with a relatively exposed active site and specificity for medium chain fatty acyl moieties.

AML rapidly hydrolysed the aliphatic plastics poly(ε-caprolactone) and poly(1,4-butylene succinate) extended with 1,6-diisocyanatohexane under mild conditions. These plastics are known to be slow …

The Rise Of Law And The Fall Of Circular 230: Tax Lawyer Professional Standards, 1985-2015, Michael Hatfield

Articles

This third article focuses on the two issues that dominated discussions of professional responsibility standards for tax lawyers in the 1985-2015 period: return position standards and tax shelter opinions. It opens with consideration of the ABA’s 1965 opinion providing “reasonable basis” as the standard for undisclosed return positions, and then traces the response to that opinion as the response prods the development of the 1985 replacement with its “realistic possibility of success” standard. The Article documents the extensive interaction between Congress, the Treasury Department, and the tax bar over the next 30 years during which penalties are studied and revised …

Towards The Point Of Care And Noninvasive Classification Of Bladder Cancer From Urine Sediment Infrared Spectroscopy. Spectral Differentiation Of Normal, Abnormal And Cancer Patients, Monika Kujdowicz, David Perezguaita, Piotr Chłosta, Krzysztof Okon, Kamilla Malek

Articles

Bladder cancer (BC) is the 9th cancer cause of death and one of most cost-intensive in the world. The diagnostic tools are still not at all satisfactory. Herein we evaluated the potential of infrared spectroscopy to detect molecular changes that precede and accompany the carcinogenesis in voided urine sediment. We collected 165 samples from patients being diagnosed for BC and measured them with attenuated total reflectance Fourier transformed infrared spectroscopy (ATR FTIR). Samples were primarily divided into three groups according to cytology that indicated the presence of normal, abnormal and cancer cells. ATR FTIR spectra of sediments were analyzed with …

From Bench To Worktop: Rapid Evaluation Of Nutritional Parameters In Liquid Foodstuffs By Ir Spectroscopy, David Perezguaita

Articles

We evaluated the use of attenuated total reflectance infrared spectroscopy for simultaneous in situ quantification of the nutritional composition of liquid food stuffs in the industrial kitchen context. Different methodologies were compared, including dry and wet acquisition along with instrument parameters and measurement times of 4 and 60 s. The most effective technique was 1-minute measurement, with prediction errors of 2.6, 0.7, 1.0, 2.2, 0.8, 2.4 g/100 mL and 150 Kcal, for carbohydrates, proteins, fat, sugars, saturated fat, water and energy values, respectively.The 4-second method resulted in larger errors but was more applicable for inline measurements. Dry measurements successfully predicted …

Repercussions Of A Weak Ocean Governance And A Non-Existent Maritime Security Policy : The Resurgence Of Piracy And Armed Robbery In The Gulf Of Mexico, Adriana Avila-Zúñiga Nordfjeld, Dimitrios Dalaklis

Articles

Piracy and armed robbery attacks against vessels at anchoring areas of ports in the Southern Gulf of Mexico and oil platforms located in the region have increased significantly during the last three years. Only during the first seven months of 2020, research efforts have documented 14 piratical attacks, but only 3 of them were officially reported to the International Maritime Organization (IMO) by the attacked vessel’s flag jurisdiction and not by Mexico, the State where these incidents occurred.

Maritime Robotics And Autonomous Systems Operations : Exploring Pathways For Overcoming International Techno-Regulatory Data Barriers, Tafsir Martin Johansson, Dimitrios Dalaklis, Aspasia Pastra

Articles

The current regulatory landscape that applies to maritime service robotics, aptly termed as robotics and autonomous systems (RAS), is quite complex. When it comes to patents, there are multifarious considerations in relation to vessel survey, inspection, and maintenance processes under national and international law. Adherence is challenging, given that the traditional delivery methods are viewed as unsafe, strenuous, and laborious. Service robotics, namely micro aerial vehicles (MAVs) or drones, magnetic-wheeled crawlers (crawlers), and remotely operated vehicles (ROVs), function by relying on the architecture of the Internet of Robotic Things. The aforementioned are being introduced as time-saving apparatuses, accompanied by the …

The Right To Benefit From Big Data As A Public Resource, Mary D. Fan

Articles

The information that we reveal from interactions online and with electronic devices has massive value—for both private profit and public benefit, such as improving health, safety, and even commute times. Who owns the lucrative big data that we generate through the everyday necessity of interacting with technology? Calls for legal regulation regarding how companies use our data have spurred laws and proposals framed by the predominant lens of individual privacy and the right to control and delete data about oneself. By focusing on individual control over droplets of personal data, the major consumer privacy regimes overlook the important question of …

Public (Ai)Ccomodations, Jevan Hutson, Deepak George, Aj Kidd, Sulaf Al-Saif, Mandy (Meiyun) Ku, Devin Glaser, Devin Glaser

Articles

This Note discusses the use of Al surveillance in places of public accommodations and its implications for civil rights and antidiscrimination law. Part I documents the extensive Al surveillance employed in areas of public accommodation, where American antidiscrimination laws explicitly provide for elevated protection. Part II uses critical race theory to explore how contemporary antidiscrimination law marries two approaches to antidiscrimination in a way that undercuts its own ability to remedy injustice. Part III reveals how antidiscrimination law fails to address issues implicated by Al surveillance in areas of public accommodations, and Part IV proposes a simple solution: abolish it.

Plasma-Treated Water Affects Listeria Monocytogenes Vitality And Biofilm Structure, Oliver Handorf

The first theme involved communication within the group and the group's approaches to working together. The second identified …

Visualizing The Impact Of Europe’S Slow Covid-19 Vaccine Rollout, Mathias Beck, Gail Sheppard

Articles

On 31 March 2021, the WHO Regional Office for Europe issued a formal statement of concern regarding the slow vaccine rollout across Europe [1]. The WHO noted that the “Region remains the second most affected by SARS-CoV-2 of all the world’s regions” which was worrying, especially because the more transmissible B.1.1.7 was now dominant in the region [1]. It further contrasted this with the experiences of the UK, by noting that according to data from Public Health England, “COVID-19 vaccines have saved, at the very least, over 6,000 lives among people over 70 since vaccination started in December 2020”. Beyond …

Label-Free Screening Of Biochemical Changes In Macrophage-Like Cells Following Mos2 Exposure Using Raman Micro-Spectroscopy, Caroline Moore, Andrew Harvety, Jonathan N. Coleman, Hugh Byrne, Jennifer Mcintyre

Articles

The emergence of large scale production techniques for 2D particulate materials has dramatically increased their applications potential. Understanding the interactions of biological cells with such particulate material is therefore of paramount importance, both for toxicological assessment and potential biomedical applications. Conventional in-vitro cytological assays commonly record only a single colorimetric end-point, and do not provide an in-depth analysis of how such materials are uptaken and processed within cells. To demonstrate its potential as an alternative, label free approach, confocal Raman micro-spectroscopy has been used to profile the cellular response of macrophage-like immune cells as a result of exposure to a …

Spatiotemporal Epidemiology Of Cryptosporidiosis In The Republic Of Ireland, 2008–2017: Development Of A Space–Time “Cluster Recurrence” Index, Martin Boudou

Articles

Approximately 1.5 million individuals in Ontario are supplied by private water wells (private groundwater supplies). Unlike municipal supplies, private well water quality remains unregulated, with owners responsible for testing, treating, and maintaining their own water supplies. The COVID-19 global pandemic and associated non-pharmaceutical interventions (NPIs) have impacted many environmental (e.g., surface water and air quality) and human (e.g., healthcare, transportation) systems over the past 15-months (January 2020 to March 2021). To date, the impact of these interventions on private groundwater systems remains largely unknown. Accordingly, the current study aimed to investigate the impact of a province-wide COVID-19 lockdown (late-March 2020) …

Articles

Multiantimicrobial-resistant Escherichia coli isolates are a global human health problem causing increasing morbidity and mortality. Genes encoding antimicrobial resistance are mainly harbored on mobile genetic elements (MGEs) such as transposons and plasmids as well as integrons, which enhance their rapid spread. The aim of this study was to characterize 83 multiantimicrobial-resistant E. coli isolates recovered from healthy broiler chickens. Among 78 tetracycline-resistant isolates, the tetA, tetB, and tetC genes were detected in 59 (75.6%), 14 (17.9%), and one (1.2%) isolates, respectively. The sul1, sul2, and sul3 genes were detected 31 (46.2%), 16 (23.8%), and 6 (8.9%) isolates, respectively, among 67 …

Carbon Futures Trading And Short-Term Price Prediction:An Analysis Using The Fractal Market Hypothesis And Evolutionary Computing, Marc Lamphiere, Jonathan Blackledge, Derek Kearney

Articles

This paper presents trend prediction results based on backtesting of the European UnionEmissions Trading Scheme futures market. This is based on the Intercontinental Exchange from 2005to 2019. An alternative trend prediction strategy is taken that is predicated on an application of theFractal Market Hypothesis (FMH) in order to develop an indicator that is predictive of short termfuture behaviour. To achieve this, we consider that a change in the polarity of the Lyapunov-to-Volatility Ratio precedes an associated change in the trend of the European Union Allowances (EUAs)price signal. The application of the FMH in this case is demonstrated to provide a …
