Artificial Intelligence Policy: A Primer And Roadmap, Ryan Calo

Articles

Talk of artificial intelligence is everywhere. People marvel at the capacity of machines to translate any language and master any game. Others condemn the use of secret algorithms to sentence criminal defendants or recoil at the prospect of machines gunning for blue, pink, and white-collar jobs. Some worry aloud that artificial intelligence will be humankind’s “final invention.” This essay, prepared in connection with UC Davis Law Review's 50th anniversary symposium, explains why AI is suddenly on everyone's mind and provides a roadmap to the major policy questions AI raises. The essay is designed to help policymakers, investors, technologists, scholars, and …

Backdating Marriage, Peter Nicolas

Articles

Many same-sex couples have been in committed relationships for years, even decades. Yet until 2004 no same-sex couples in the United States had the right to marry in any state and until the U.S. Supreme Court's 2015 decision in Obergefell v. Hodges the right was unavailable to same-sex couples nationwide. Due to this longstanding denial of the right to marry, most same-sex relationships appear artificially short when measured solely by reference to the couple's civil marriage date.

This circumstance has important legal consequences for many same-sex couples, as a number of rights associated with marriage are tied not merely to …

A Transactional Theory Of The Reader In Copyright Law, Zahr K. Said

Articles

Copyright doctrine requires judges and juries to engage in some form of experiencing or “reading” artistic works to determine whether these works have been infringed. Despite the central role that this reading—or viewing, or listening—plays in copyright disputes, copyright law lacks a robust theory of reading, and of the proper role for the “reader.” Reading matters in copyright cases, first, because many courts rely on the “ordinary observer” standard to determine infringement, which requires figuring out or assuming how an ordinary observer would read the works at issue. Second, most courts characterize a key part of infringement analysis as a …

How Adverse Outcome Pathways Can Aid The Development And Use Of Computational Prediction Models For Regulatory Toxicology, Clemens Wittwehr, Hristo Aladjov, Gerald Ankley, Hugh Byrne, Joop Deknecht

Articles

Efforts are underway to transform regulatory toxicology and chemical safety assessment from a largely empirical science based on direct observation of apical toxicity outcomes in whole organism toxicity tests to a predictive one in which outcomes and risk are inferred from accumulated mechanistic understanding. The adverse outcome pathway (AOP) framework provides a systematic approach for organizing knowledge that may support such inference. Likewise, computational models of biological systems at various scales provide another means and platform to integrate current biological understanding to facilitate inference and extrapolation. We argue that the systematic organization of knowledge into AOP frameworks can inform and …

In Vitro Comparative Cytotoxicity Study Of Aminated Polystyrene, Zinc Oxide And Silver Nanoparticles On A Cervical Cancer Cell Line, Akash Sharma, Brian Gorey, Alan Casey

Articles

Nanoparticles use in nano-biotechnology applications have increased significantly with Aminated polystyrene amine (AmPs NP), Zinc oxide (ZnO NP), and Silver (Ag NP) nanoparticles utilized in wide variety of consumer products. This has presented a number of concerns due to their increased exposure risks and associated toxicity on living systems. Changes in the structural and physicochemical properties of nanoparticles can lead to changes in biological activities. This study investigates, compares, and contrasts the potential toxicity of AmPs, ZnO and Ag NPs on an in vitro model (HeLa cells) and assesses the associated mechanism for their corresponding cytotoxicity relative to the surface …

Carbon Nanomaterials And Their Application To Electrochemical Sensors: A Review, Aoife Power, Shaneel Chandra, Brian Gorey, James Chapman

Articles

Carbon has long been applied as an electrochemical sensing interface owing to its unique electrochemical properties. Moreover, recent advances in material design and synthesis, particularly nanomaterials, has produced robust electrochemical sensing systems that display superior analytical performance. Carbon nanotubes (CNTs) are one of the most extensively studied nanostructures because of their unique properties. In terms of electroanalysis, the ability of CNTs to augment the electrochemical reactivity of important biomolecules and promote electron transfer reactions of proteins is of particular interest. The remarkable sensitivity of CNTs to changes in surface conductivity due to the presence of adsorbates permits their application as …

A Natural Calcium-Rich Multi-Mineral Complex Preserves Bones Structure, Composition And Strength In An Ovariectomized Rat Model Of Osteoporosis, Orlaith Brennan, Joseph Sweeney, Brian O'Meara, Amro Widaa, Franck Bonnier, Hugh Byrne, Denise O'Gorman, Fergal O'Brien

Articles

Calcium supplements are used as an aid in the prevention of osteopenia and osteoporosis and also for the treatment of patients when used along with medication. Many of these supplements are calcium carbonate based. This study compared a calcium-rich, marine multi-mineral complex (Aquamin) to calcium carbonate in an ovariectomised rat model of osteoporosis in order to assess Aquamin’s efficacy in preventing the onset of bone loss. Animals were randomly assigned to either non-ovariectomy control (Control), ovariectomy (OVX) plus calcium carbonate, ovariectomy plus Aquamin or ovariectomy plus Aquamin delay where Aquamin treatment started 8 weeks post OVX. At the end of …

Articles

Circulating tumor cells (CTCs) from peripheral blood account genetic information for cancer diagnosis and overall disease monitoring. Analysis of “liquid biopsy” holds immense promise as it may lead to new approaches for cancer treatment. The study reports effective and continuous flow microchannel system for isolating CTCs using transferrin conjugated 3D matrix synthesized by crosslinking polyethylene glycol-Fe3O4 nanostructures for rapid and efficient capturing of CTCs. The platform provides option of using multiple microchannel units in series that can influence higher cell-capture efficiency due to increasing cell-substrate contact frequency. CTCs are captured with high efficiency even at low concentration of target cells …

Integration Of Biological Effects, Fish Histopathology And Contaminant Measurements For The Assessment Of Fish Health: A Pilot Application In Irish Marine Waters, Michelle Giltrap, Jenny Ronan, John Bignell, Brett Lyons, Evelyn Collins, Heather Rochford, Brendan Mchugh, Evin Mcgovern, Lorraine Bull, James Wilson

Articles

This study investigates the use of a weight of evidence (WOE) approach to evaluate fish health status and biological effects (BEs) of contaminants for assessment of ecosystem health and discusses its potential application in support of the Marine Strategy Framework Directive (MSFD). External fish disease, liver histopathology and several BEs of contaminant exposure including 7-ethoxy resorufin O-de-ethylase (EROD), acetylcholinesterase (AChE), bile metabolites, vitellogenin (VTG) and alkali labile phosphates (ALP) were measured in two flatfish species from four locations in Ireland. Contaminant levels in fish were generally low with PCBs in fish liver below OSPAR environmental assessment criteria (EAC). There were …

An Enhanced Spring-Particle Model For Red Blood Cell Structural Mechanics: Application To The Stomatocyte–Discocyte– Echinocyte Transformation, Mingzhu Chen, Fergal Boyle

Articles

Red blood cells (RBCs) are the most abundant cellular element suspended in blood. Together with the usual biconcave-shaped RBCs, i.e., discocytes, unusual-shaped RBCs are also observed under physiological and experimental conditions, e.g., stomatocytes and echinocytes. Stomatocytes and echinocytes are formed from discocytes and in addition can revert back to being discocytes; this shape change is known as the stomatocyte–discocyte–echinocyte (SDE) transformation. To-date, limited research has been conducted on the numerical prediction of the full SDE transformation. Spring- particle RBC (SP-RBC) models are commonly used to numerically predict RBC mechanics and rheology. However, these models are incapable of predicting the full …

Articles

The top-performing linear poly(β-amino ester) (LPAE), poly(5-amino-1-pentanol-co-1,4-butanediol diacrylate) (C32), has demonstrated gene transfection efficiency comparable to viral-mediated gene delivery. Herein, we report the synthesis of a series of highly branched poly(5-amino-1-pentanol-co-1,4-butanediol diacrylate) (HC32) and explore how the branching structure influences the performance of C32 in gene transfection. HC32 were synthesized by an “A2 + B3 + C2” Michal addition strategy. Gaussia luciferase (Gluciferase) and green fluorescent protein (GFP) coding plasmid DNA were used as reporter genes and the gene transfection efficiency was evaluated in human cervical cancer cell line (HeLa) and human recessive dystrophic epidermolysis bullosa keratinocyte (RDEBK) cells. We …

The Potential Of Atmospheric Air Cold Plasma For Control Of Bacterial Contaminants Relevant To Cereal Grain Production, Agata Los, Dana Ziuzina, Daniela Boehm, Patrick J. Cullen, Paula Bourke

Articles

The aim of this work was to investigate the efficacy of dielectric barrier discharge atmospheric cold plasma (DBD ACP) against bacteria associated with grains quality and safety. ACP inactivation efficacy was tested against biofilms formed by different strains of E. coli, Bacillus and Lactobacillus in grain model media and against B. atrophaeus endospores either in grain media or attached on abiotic surfaces. Effects were dependent on bacterial strain, media composition and mode of ACP exposure. ACP treatment for 5min reduced E. coli spp., B. subtilis and Lactobacillus spp. biofilms by >3 log10, whereas insignificant reductions were achieved for B. atrophaeus. …

Facilitating Smart Haccp Strategies With Process Analytical Technology, Fintan Moran, Carl Sullivan, Kevin Keener, Patrick J. Cullen

Articles

The critical feature to any food management system, be it safety or quality focused, is timely and accurate product and process data. The HACCP framework is one of a systematic preventive approach that addresses hazards as a means of prevention rather than finished product inspection. The PAT initiative is a framework which also aims to change product assurance from end-product testing to preventive control through timely measurements of critical product and process parameters. The continued emergence of sensitive yet affordable sensors capable of direct measurement of biological, chemical and physical risks associated with foods during production, processing or over their …

Articles

An all-fiber magnetic field sensor based on whispering-gallery modes (WGM) in a fiber micro-resonator infiltrated with ferronematic liquid crystal is proposed and experimentally demonstrated. The cylindrical microresonator is formed by a 1 cm-long section of a photonic crystal fiber infiltrated with ferronematic materials. Both ferronematics suspensions are prepared based on the nematic liquid crystal 1-(trans-4-Hexylcyclohexyl)-4-isothiocyanatobenzene (6CHBT) doped with rod-like magnetic particles in the first case and with spherical magnetic particles in the second case. WGMs are excited in the fiber microresonator by evanescent light coupling using a tapered fiber with a micron-size diameter. The Q-factor of the microresonator determined from …

An Equal Rights Amendment For The Twenty-First Century: Bringing Global Constitutionalism Home, Julie C. Suk

Articles

The last few years have seen a renewed push to constitutionalize sex equality in the United States. A generation after the federal Equal Rights Amendment (ERA) failed to be ratified by the requisite number of states, the ERA is on the platform of the 2017 Women's March on Washington. Oregon added a sex equality guarantee to its state constitution in 2014, joining 22 state constitutions and most constitutions around the world. Feminist coalitions, Hollywood celebrities, and members of Congress are vocally endorsing an ERA revival. Why is an ERA desired now, when judges have interpreted the Fourteenth Amendment to prohibit …

Impact Of Supplemental Home Enteral Feeding Postesophagectomy On Nutrition, Body Composition, Quality Of Life, And Patient Satisfaction, C.L. Donohoe, L.A. Healy, M. Fanning, Suzanne Doyle, A. Mchugh, J. Moore, N. Ravi, J.V. Reynolds

Articles

The aim of this prospective cohort study is to analyze the impact of supplemental home enteral nutrition (HEN) post-esophageal cancer surgery on nutritional parameters, quality of life (QL), and patient satisfaction. A systematic review reported that over 60% of patients lose >10% of both body weight and BMI by 6 months after esophagectomy. Enteral feeding (EF) is increasingly a modern standard postoperatively; however, the impact of extended HEN postdischarge has not been systematically studied. One hundred forty-nine consecutive patients [mean age 62 ± 9, 80% male,76% adenocarcinoma, 66% on multimodal protocols, and 69% with BMI ≥ 25 kg/m2] were studied. …

Articles

Aim This observational ecological study aims to compare Ireland’s age-specific cancer incidence rates (ASRs) with equivalent European and global data and to highlight possible dietary, nutritional and lifestyle contributors to cancer in Ireland.

Subjects and methods Using the International Agency for Research on Cancer’s (IARC) GLOBOCAN database, Irish ASRs for all-site cancer and for "lifestyle-related" cancers such as those of the colo-rectum, oesophagus, breast, lung and prostate were compared with European and global incidence data. Irish dietary and nutrient intake data were reviewed and evaluated in the context of these cancer incidence data and in relation to the established dietary, …

Pcr-Ribotype Distribution Of Clostridium Difficile In Irish Pigs, Katharina Stein, Sarah Egan, Helen Lynch, Celine Harmanus, Lorraine Kyne, Celine Herra, Sinead Mcdermott, Ed Kuijper, Fidelma Fitzpatrick, Susan Fitzgerald, Lynda Fenelon, Denise Drudy

Articles

Clostridium difficile is an important enteric pathogen in humans causing infections in the healthcare environment and the community. Carriage of C. difficile and C. difficile-related enterocolitis has been reported in piglets worldwide. The aim of this study was to investigate the rates of C. difficile isolation from pigs in Ireland. Faecal samples from piglet litters and sows were collected from six farms in 2015. The sows were non-diarrhoeal at the time of sampling. The diarrhoeal status of the piglets was unknown. C. difficile was isolated from 34/44 (77%) of piglet litter samples and from 33/156 (21%) of sow samples. The …

Regulating Cumulative Risk, Sanne H. Knudsen

Articles

This Article proceeds in four parts. Part I describes how cumulative risk assessments tackle the real-world exposure problems that lie at the heart of public health. It shows how risk science has evolved and why policy, not science, lags behind. Part II then examines why key public health concerns cannot be answered through information disclosure or consumer choice models alone.

Having established that regulatory drivers are needed, Part III begins to examine how to move forward. It does so by looking backward and examining how TSCA and FIFRA have failed historically to provide this critical public health focus despite room …

Expired Patents, Trade Secrets, And Stymied Competition, W. Nicholson Price Ii

Articles

Patents and trade secrecy have long been considered substitute incentives for innovation. When inventors create a new invention, they traditionally must choose between the two. And if inventors choose to patent their invention, society provides strong legal protection in exchange for disclosure, with the understanding that the protection has a limit: it expires twenty years from the date of filing. At that time, the invention is opened to the public and exposed to competition. This story is incomplete. Patent disclosure is weak and focuses on one technical piece of an invention—but that piece is often only a part of the …

The Constitution Of Mothers: Gender Equality And Social Reproduction In The United States And The World, Julie C. Suk

Articles

The article explores the resurgence of the Equal Rights Amendment (ERA) in the United States, highlighting its potential to address ongoing gender inequalities and the role of social reproduction in modern society. It argues that the ERA, if ratified, could move beyond symbolic significance by integrating lessons from global constitutionalism, particularly the synthesis of gender equality and motherhood protections seen in European constitutions.

What We Think, What We Know And What We Think We Know About False Convictions, Samuel Gross

Articles

False convictions are notoriously difficult to study because they can neither be observed when they occur nor identified after the fact by any plausible research strategy. Our best shot is to collect data on those that come to light in legal proceedings that result in the exoneration of the convicted defendants. In May 2012, the National Registry of Exonerations released its first report, covering 873 exonerations from January 1989 through February 2012. By October 15, 2016, we had added 1,027 cases: 599 exonerations since March 1, 2012, and 428 that had already happened when we issued our initial report but …

Addressing Cultural Bias In The Legal Profession, Debra Chopp

Articles

Over the past two decades, there has been an outpouring of scholarship that explores the problem of implicit bias. Through this work, commentators have taken pains to define the phenomenon and to describe the ways in which it contributes to misunderstanding, discrimination, inequality, and more. This article addresses the role of implicit cultural bias in the delivery of legal services. Lawyers routinely represent clients with backgrounds and experiences that are vastly different from their own, and the fact of these differences can impede understanding, communication, and, ultimately, effective representation. While other professions, such as medicine and social work, have adopted …

Design Of A Compact, Fully-Autonomous 433 Mhz Tunable Antenna For Wearable Wireless Sensor Applications, John Buckley, Kevin Mccarthy, Domenico Gaetano, Loizos Loizou, Brendan O'Flynn, Cian O'Mathuna

Articles

The authors present the design of a tunable 433 MHz antenna that is tailored for wearable wireless sensor applications. This study first presents a detailed analysis of the measured impedance characteristics of a chosen antenna under test (AUT) in varying proximity to a human test subject. Instead of limiting the analysis to the head and hand only, this analysis measures the AUT impedance at varying distances from 11 different body positions. A novel antenna equivalent circuit model is then developed that enables both the free-space and total on-body AUT impedance variation to be rapidly computed using a circuit simulator instead …

Disrupted Superior Collicular Activity May Reveal Cervical Dystonia Disease Pathomechanisms, Eavan M. Mcgovern, Owen Killian, Shruti Narashimham, Brendan Quinlivan, John Butler, Rebecca Beck, Ines Beiser, Laura W. Williams, Ronan P. Killeen, Michael Farrell, Sean O'Riordan, Richard B. Reilly, Michael Hutchinson

Articles

Cervical dystonia is a common neurological movement disorder characterised by muscle contractions causing abnormal movements and postures affecting the head and neck. The neural networks underpinning this condition are incompletely understood. While animal models suggest a role for the superior colliculus in its pathophysiology, this link has yet to be established in humans. The present experiment was designed to test the hypothesis that disrupted superior collicular processing is evident in affected patients and in relatives harbouring a disease-specific endophenotype (abnormal temporal discrimination). The study participants were 16 cervical dystonia patients, 16 unaffected first-degree relatives with abnormal temporal discrimination, 16 unaffected …

Humic Acid And Trihalomethane Breakdown With Potential By-Product Formations For Atmospheric Air Plasma Water Treatment, Chaitanya Sarangapani, Peng Lu, Patrice Behan, Paula Bourke, Patrick J. Cullen

Articles

Over the past century chlorine has been widely used as an oxidant in water and wastewater treatment. Chlorine’s efficacy is demonstrated for microbial inactivation of a wide variety of pathogens along with oxidation of various chemical contaminants. However, the potential formation of disinfection by-products (DBPs), such as trihalomethane, is a concern [1]. DBPs, including trihalomethanes, can be formed as a consequence of the reaction of chlorine with natural organic matter (NOM) present in both surface and ground water [2]. NOM comprises of two fractions; humic substances (HS), which are composed of humic acids, fulvic acids, and non-humic substances (non-HS), which …
