Miniaturized Dual-Band Antenna Array With Double-Negative (Dng) Metamaterial For Wireless Applications, Abdulrahman Shueai Mohsen Alqadami, Mohd Faizal Jamlos, Ping Jack Soh, Sharul Kamal Abdul Rahim, Guy Vandenbosch, Adam Narbudowicz

Articles

A miniaturized dual-band antenna array using a negative index metamaterial is presented for WiMAX, LTE, and WLAN applications. This left-handed metamaterial plane is located behind the antenna array, and its unit cell is a combination of split-ring resonator, square electric ring resonator, and rectangular electrical coupled resonator. This enables the achievement of a metamaterial structure exhibiting both negative permittivity and permeability, which results in antenna size miniaturization, efficiency, and gain enhancement. Moreover, the proposed metamaterial antenna has realized dual-band operating frequencies compared to a single frequency for normal antenna. The measured reflection coefficient (S11) shows a 50.25% bandwidth in the …

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. …

Cohabiting With Property In Washington: Washington's Committed Intimate Relationship Doctrine, Tom Andrews

Articles

Washington has followed a community property system since at least 1869—twenty years prior to statehood. However, Washington rejected the doctrine of common law marriage quite early in 1892. For over one hundred years, in order to receive the advantages of the community property laws, a Washington couple has needed to have their relationship blessed with a ceremonial marriage or have a valid common law marriage in another state.

Accompanying these requirements for the formal establishment of a community property regime was the so-called "Creasman Presumption," which provided that "property acquired by a man and a woman not married to each …

The Taking Economy: Uber, Information, And Power, Ryan Calo, Alex Rosenblat

Articles

Sharing economy firms such as Uber and Airbnb facilitate trusted transactions between strangers on digital platforms. This creates economic and other value but raises concerns around racial bias, safety, and fairness to competitors and workers that legal scholarship has begun to address. Missing from the literature, however, is a fundamental critique of the sharing economy grounded in asymmetries of information and power.

This Essay, coauthored by a law professor and a technology ethnographer who studies work, labor, and technology, furnishes such a critique and proposes a meaningful response through updates to consumer protection law. Commercial firms have long used what …

Industry Lobbying And "Interest Blind" Access Norms At International Organizations, Melissa J. Durkee

Articles

The standard approach of international organizations (IOs) makes no formal distinctions between nonprofit private sector associations, known as trade or industry groups, and public interest groups like Amnesty International or Greenpeace. After all, these groups are all organized as nonprofits; they may all be characterized as nongovernmental organizations representing the interests of their memberships; and the groups all seek to advance the agendas of members by offering ideas and expertise to international officials or bodies—classic lobbying activity. Thus, most IOs offer accreditation and access to both private sector and public interest groups on equal terms, without differentiating between them. I …

Hacking Qualified Immunity: Camera Power And Civil Rights Settlements, Mary D. Fan

Articles

Excessive force cases are intensely fact-specific. Did the suspect resist, necessitating the use offorce? What threat did the suspect pose, if any? Was the use of force excessive in light of the situation? These are judgment calls based on myriad facts that differ from case to case. Establishing what really happened forces courts and juries to wade into a fact-bound morass filled with fiercely conflicting defendant-said, police-said battles.

Now an evidentiary transformation is underway. We are in an era where the probability of a police encounter being recorded has never been higher. With the rise of recording—by the public as …

Justice Visualized: Courts And The Body Camera Revolution, Mary D. Fan

Articles

What really happened? For centuries, courts have been magisterially blind, cloistered far away from the contested events that they adjudicate, relying primarily on testimony to get the story—or competing stories. Whether oral or written, this testimony is profoundly human, with all the passions, partisanship and imperfections of human perception.

Now a revolution is coming. Across the nation, police departments are deploying body cameras. Analyzing body camera policies from police departments across the nation, the article reveals an unfolding future where much of the main staple events of criminal procedure law will be recorded. Much of the current focus is on …

The Vested Rights Doctrine: How A Shield Against Injustice Became A Sword For Opportunistic Developers, Steve P. Calandrillo, Chryssa Deliganis, Christina Elles

Articles

In an era of pioneering environmental and land use laws, savvy developers are using the “vested rights” doctrine to circumvent and undermine critical public health, safety, and environmental regulations. This controversy pits two legitimate interests against each other: On the one hand, local governments must have the power to pass land use laws and regulations in the public interest to protect their community’s health, safety, welfare, and environment. On the other, developers who rely on the laws in existence at the time their project is approved should be protected from subsequent changes to the law that could increase transactional costs …

Standards Of Review In Law And Sports: How Instant Replay's Asymmetric Burdens Subvert Accuracy And Justice, Steve P. Calandrillo, Joseph Davison

Articles

A fundamental tension exists in both law and sports: on one hand, adjudicators must “get the decision right” in order to provide fairness to the parties involved, but on the other, they must issue speedy and certain rulings to avoid delaying justice. The certainty principle dictates that courts follow stare decisis in the law even if they believe that an earlier decision was wrong. However, it is often the case that there is a need to reverse earlier decisions or the law itself in order to make the correct call on appeal.

Both law and sports are constantly balancing the …

Electoral Evidence, Peter Nicolas

Articles

Each year, millions of Americans cast votes for specific candidates or on specific ballot measures. Each such vote generates potential "electoral evidence," the admissibility of which may be the subject of dispute in subsequent litigation. The evidence may take various forms, including the marked ballot itself, a voter's testimony regarding her vote, or her written or oral statements regarding her vote.

Electoral evidence is most commonly offered in litigation over the election outcome itself, with the parties seeking to determine how certain individuals voted to resolve a close election. However, its potential relevance is not limited to such proceedings. It …

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 …

The Other Securities Regulator: A Case Study In Regulatory Damage, Anita K. Krug

Articles

Although the Securities and Exchange Commission is the primary securities regulator in the United States, the Department of Labor also engages in securities regulation. It does so by virtue of its authority to administer the Employee Retirement Income Security Act (ERISA), the statute that governs the investment of retirement assets. In 2016, the DOL used its securities regulatory authority to adopt a rule that, for the first time, designates securities brokers who provide investment advice to retirement investors as fiduciaries subject to ERISA's stringent transaction prohibitions. The new rule's objective is salutary, to be sure. However this Article shows that, …

Quantification Of Rubidium As A Trace Element In Beef Using Laser Induced Breakdown Spectroscopy, Yash Dixit, Maria Piedad Casado-Gavalda, Raquel Cama-Moncunill, Xavier Cama-Moncunill, Patrick J. Cullen, Carl Sullivan

Articles

This study evaluates the potential of laser induced breakdown spectroscopy (LIBS) coupled with chemometrics to develop a quantification model for rubidium (Rb) in minced beef. A LIBSCAN 150 system was used to collect LIBS spectra of minced beef samples. Beef liver was used to spike the Rb levels in minced beef. All samples were dried, powdered and pelleted using a hydraulic press. Measurements were conducted by scanning 100 different locations with an automated XYZ sample chamber. Partial least squares regression (PLSR) was used to develop the calibration model, yielding a calibration coefficient of determination (Rc2) of 0.99 and a root …

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 …

Women derived pregnancy-related nutritional information from …

Extraction And Quantification Of Sinapinic Acid From Irish Rapeseed Meal And Assessment Of Angiotensin-I Converting Enzyme (Ace-I) Inhibitory Activity, Leah Quinn, Steven Gray, Steve Meaney, Stephen Finn, Padraig Mcloughlin, Maria Hayes

Articles

Phenolic compounds, including phenolic acids, are known to play a protective role against the development of cardiovascular disease. The aim of this work was to generate a phenolic acid extract from Irish rapeseed meal, to determine the quantity of sinapinic acid (SA) in this fraction and to assess the ability of this fraction to inhibit the enzyme angiotensin-I converting enzyme (ACE-I; EC 3.4.15.1). A crude phenolic extract (fraction 1), free phenolic acid containing extract (fraction 2), and an extract containing phenolic acids liberated from esters (fraction 3) were generated from Irish rapeseed meal using a methanol:acetone:water solvent mixture (7:7:6). The …

Assessment Of Mental Workload: A Comparison Of Machine Learning Methods And Subjective Assessment Techniques, Karim Moustafa, Saturnino Luz, Luca Longo

Articles

Mental workload (MWL) measurement is a complex multidisciplinary research field. In the last 50 years of research endeavour, MWL measurement has mainly produced theory-driven models. Some of the reasons for justifying this trend includes the omnipresent uncertainty about how to define the construct of MWL and the limited use of datadriven research methodologies. This work presents novel research focused on the investigation of the capability of a selection of supervised Machine Learning (ML) classification techniques to produce data-driven computational models of MWL for the prediction of objective performance. These are then compared to two state-of-the-art subjective techniques for the assessment …

A Software Development Process For Freshman Undergraduate Students, Catherine Higgins, Fredrick Mtenzi, Ciaran O'Leary, Orla Hanratty, Claire Mcavinia

Articles

This conceptual paper presents work which is part of an ongoing research project into the design of a software development process aimed at freshman, undergraduate computing students. The process of how to plan and develop a solution is a topic that is addressed very lightly in many freshman, undergraduate courses which can leave novices open to developing habit-forming, maladaptive cognitive practices. The conceptual software development process described in this paper has a learning process at its core which centres on declarative knowledge (in the form of threshold concepts) and procedural knowledge (in the form of computational thinking skills) scaffolding freshman …

A Conceptual Framework For A Software Development Process Based On Computational Thinking, Catherine Higgins, Ciaran O'Leary, Orla Hanratty, Fredrick Mtenzi

Articles

A software development process is a mechanism for problem solving to help software developers plan, design and structure the development of software to solve a problem. Without a process to guide the structured evolution of a solution, it is extremely likely that at least some aspect of the resulting software will be omitted or incorrectly implemented. Even though the importance of utilising a software process for solving problems is accepted in the business and academic communities, it is a topic that is addressed very lightly (if at all) in most freshman undergraduate computing courses with most courses focussing on programming …

Assessing Peer Review By Gauging The Fate Of Rejected Manuscripts: The Case Of The Journal Of Artificial Societies And Social Simulation, Niccolò Casnici, Francisco Grimaldo, Nigel Gilbert, Pierpaolo Dondio, Flaminio Squazzoni

Articles

This paper investigates the fate of manuscripts that were rejected from JASSS-The Journal of Artificial Societies and Social Simulation, the flagship journal of social simulation. We tracked 456 manuscripts that were rejected from 1997 to 2011 and traced their subsequent publication as journal articles, conference papers or working papers. We compared the impact factor of the publishing journal and the citations of those manuscripts that were eventually published against the yearly impact factor of JASSS and the number of citations achieved by the JASSS mean and top cited articles. Only 10% of the rejected manuscripts were eventually published in a …

Improved Protocols For Pre-Processing Raman Spectra Of Formalin Fixed Paraffin Preserved Tissue Sections, Hugh Byrne, Fiona Lyng, Ola Ibrahim, Adrian Maguire, Aidan Meade, Steven Flint, M. Toner

Articles

Although formalin fixed paraffin preserved (FFPP) tissues are a major resource for retrospective studies of disease progression, their use in vibrational spectroscopy studies has been undermined by issues of contributions of substrate and paraffin wax which persist in the spectra and can compromise spectral analysis. Recognising the microcrystalline nature of the wax in the tissue, which are inhomogeneously oriented with respect to the polarisation of the Raman source laser, in this study, we have developed a novel method for removing the paraffin wax contributions to the spectra using matrices of multiple wax spectra. FFPP tissue sections from the oral mucosa …

Development Of Methodology For Raman Microspectroscopic Analysis Of Oral Exfoliated Cells, Hugh Byrne, Fiona Lyng, Alison Malkin, Ola Ibrahim, Genecy Calado, Steven Flint, Isha Behl

Articles

Oral squamous cell carcinoma ranks as the 15th most common cancer worldwide. The present study was undertaken to standardise a protocol for the analysis of oral exfoliated cells using Raman microspectroscopy. For this purpose, samples were obtained from two different sites, based on prevalence of disease (ventral side of the tongue and buccal mucosa). Different oral rinsing agents were employed and it was concluded that non-alcoholic mouthwash adequately removes food debris. Samples were collected using various collection tools and compared. It was observed that endo-cervical brushes yielded cells from deeper layers of the epithelium. Furthermore, monolayer formation of cells was …

Articles

Heat waves of all definitions had significant cumulative associations with mortality in all countries, but varied by community. The higher the temperature threshold used to define heat waves, the higher heat wave associations on mortality. However, heat wave duration did not modify the impacts. The association between heat waves and mortality appeared acutely and lasted for 3 and 4 d. Heat waves had higher associations with mortality in moderate cold and moderate hot areas than cold and hot areas. There were no added effects of heat waves on mortality in all countries/regions, except for Brazil, Moldova, and Taiwan. Heat waves …

High-latitude ecosystems have the capacity to release large amounts of carbon dioxide (CO2) to the atmosphere in response to increasing temperatures, representing a potentially significant positive feedback within the climate system. Here, we combine aircraft and tower observations of atmospheric CO2 with remote sensing data and meteorological products to derive temporally and spatially resolved year-round CO2 fluxes across Alaska during 2012-2014. We find that tundra ecosystems were a net source of CO2 to the atmosphere annually, with especially high rates of respiration during early winter (October through December). Long-term records at Barrow, AK, suggest that CO2emission rates from North Slope …

Summary Background Climate change can directly affect human health by varying exposure to non-optimal outdoor temperature. However, evidence on this direct impact at a global scale is limited, mainly due to issues in modelling and projecting complex and highly heterogeneous epidemiological relationships across different populations and climates. Methods We collected observed daily time series of mean temperature and mortality counts for all causes or non-external causes only, in periods ranging from Jan 1, 1984, to Dec 31, 2015, from various locations across the globe through the Multi-Country Multi-City Collaborative Research Network. We estimated temperature–mortality relationships through a two-stage time series …
