Discordant Alternans Mechanism For Initiation Of Ventricular Fibrillation In Vitro, Laura M. Muñoz, Anna R.M. Gelzer, Flavio H. Fenton, Wei Qian, Weiye Lin, Robert F. Gilmour Jr, Niels F. Otani

Articles

Background: Ventricular tachyarrhythmias are often preceded by short sequences of premature ventricular complexes. In a previous study, a restitution-based computational model predicted which sequences of stimulated premature complexes were most likely to induce ventricular fibrillation in canines in vivo. However, the underlying mechanism, based on discordant-alternans dynamics, could not be verified in that study. The current study seeks to elucidate the mechanism by determining whether the spatiotemporal evolution of action potentials and initiation of ventricular fibrillation in in vitro experiments are consistent with model predictions. Methods and Results: Optical mapping voltage signals from canine right-ventricular tissue (n=9) were obtained simultaneously …

Greenhouse Gas Sensors Fabricated With New Materials For Climatic Usage: A Review, Kalathur S.V. Santhanam, Nuzhet Nihaar Nasir Ahamed

Articles

With the increasing utilization of fossil fuels in today’s technological world, the atmosphere’s concentration of greenhouse gases is increasing and needs to be controlled. In order to achieve this goal, it is imperative to have sensors that can provide data on the greenhouse gases in the environment. The recent literature contains a few publications that detail the use of new methods and materials for sensing these gases. The first part of this review is focused on the possible effects of greenhouse gases in the atmosphere, and the second part surveys the developments of sensors for greenhouse gases with coverage on …

The Persistence Of The Probabilistic Perspective, Richard D. Friedman

Articles

The publication now of an essay written by Craig Callen nearly a decade ago is cause for wistful celebration. Even while we are reminded how suddenly and prematurely Craig’s life ended, it is good to have one more academic contribution from him, especially because it is marked by the erudition, thoroughness, gentleness, and humor that characterized him.

On The Nonexistence Of Some Generalized Folkman Numbers, Xiaodong Xu, Meilian Liang, Stanislaw Radziszowski

Articles

For an undirected simple graph $G$, we write $G \rightarrow (H_1, H_2)^v$ if and only if for every red-blue coloring of its vertices there exists a red $H_1$ or a blue $H_2$. The generalized vertex Folkman number $F_v(H_1, H_2; H)$ is defined as the smallest integer $n$ for which there exists an $H$-free graph $G$ of order $n$ such that $G \rightarrow (H_1, H_2)^v$. The generalized edge Folkman numbers $F_e(H_1, H_2; H)$ are defined similarly, when colorings of the edges are considered. We show that $F_e(K_{k+1},K_{k+1};K_{k+2}-e)$ and $F_v(K_k,K_k;K_{k+1}-e)$ are well defined for $k \geq 3$. We prove the nonexistence of …

Digital Ldo Modelling Techniques For Performance Estimation At Early Design Stage, Haibo Wang, Stefan Leitner

Articles

This work studies the transient responses and steady-state ripples of digital low dropout (LDO) voltage regulators. Simulation models as well as closed-form expressions are provided for estimating the LDO output settling behaviour after load current or reference voltage changes. Estimation equations for the magnitude and frequency of LDO output steady-state ripples are also presented. The accuracy of the developed models is verified by comparing estimation data with results obtained from circuit simulations. The use of the developed estimation equations in design space exploration is also demonstrated.

Sites Of Storytelling: Supreme Court Confirmation Hearings, Patrick Barry

Articles

Supreme Court confirmation hearings have an interesting biographical feature: before nominees even say a word, many words are said about them. This feature— which has been on prominent display in the confirmation hearings of Judge Brett Kavanaugh—is a product of how each senator on the confirmation committee is allowed to make an opening statement. Some of these statements are, as Robert Bork remembers from his own confirmation hearing, “lavish in their praise,” some are “lavish in their denunciations,” and some are “lavish in their equivocations.”1 The result is a disorienting kind of biography by committee, one which produces not one …

Paragraphing, Patrick Barry

Articles

Consider treating the word paragraph as a verb. Think of it as something you can do well or poorly, with major consequences for your readers. Good paragraphers, for example, help readers. They make it easy to navigate and absorb information. They don’t flit around, hastily moving on to the next point before fully supporting their first. Nor do they get stuck for too long in one place. Instead, they give a lot of thought not just to the ideas but also to their arrangement—their shape, their balance, their pace.

Show And Tell, Patrick Barry

Articles

“Show don’t tell.” Teachers preach these words. Style guides endorse them. And you’d be hard pressed to find any editor or law firm partner who hasn’t offered them as feedback in the last year, month, week, maybe even day. There’s only one problem: “Show don’t tell” is bad advice. Or at least, it is incomplete advice.

Alliteration, Restraint, And A Mind At Work, Patrick Barry

Articles

Alliteration is great—until it’s not. You can pretty quickly overdo it, though I don’t think any major professional sports franchise has yet. The Boston Bruins, the Seattle Seahawks, the Cleveland Cavaliers: these names all have a nice ring to them. As do countless others, from the Washington Wizards to the Tennessee Titans to the Buffalo Bills. The sounds run quickly off your tongue and not unpleasantly into the air. They’re not irritating or obnoxious—unless maybe you’re a fan of the opposing team.

Serialised Holography For Brand Protection And Authentication, Dinesh Vather, Izabela Naydenova, Dervil Cody, Monika Zawadzka, Suzanne Martin, Emilia Mihaylova, Stephen Curran, Paul Duffy, Josune Portillo, Daniel Connell, Stephen Mcdonnell, Vincent Toal

Articles

The problems presented by counterfeit products and documentation are discussed. Limitations of existing holograms for anti-counterfeit applications are described. We describe the advantages of full holographic serialisation and the requirements in terms of materials and techniques for mass production of true serialised holograms. These requirements having been met, we report for the first time the mass production of fully serialised holograms. The novelty of approach consists of the direct use of product manufacturer’s information as the object in a holographic recording system along with a self-processing photopolymer and modular optical system to facilitate mass production of truly serialised volume holograms. …

Drug Approval In A Learning Health System, W. Nicholson Price

Articles

The current system of FDA approval seems to make few happy. Some argue FDA approves drugs too slowly; others too quickly. Many agree that FDA—and the health system generally—should gather information after drugs are approved to learn how well they work and how safe they are. This is hard to do. FDA has its own surveillance systems, but those systems face substantial limitations in practical use. Drug companies can also conduct their own studies, but have little incentive to do so, and often fail to fulfil study commitments made to FDA. Proposals to improve this dynamic often suggest gathering more …

The Rockingham Shoot And Other Dramatic Writings Review: Good But Not Great, Eamon Maher

Articles

John McGahern is rightly renowned for his carefully crafted prose, his skill at describing characters and situations that have a universal resonance and his uncannily accurate representation of the people and places associated with his native Roscommon and Leitrim. Author of six novels, two short story collections (many of which were brought together in The Collected Stories and the posthumously published Creatures of the Earth, which contains significant new material) and a highly successful memoir, McGahern won several literary prizes and warm critical acclaim. Faber has now brought out a collection of his dramatic writings, a genre in which, …

Residential solar PV Positive feedback cycle Panel data analysis

1. Introduction

Micro renewable energy systems are small scale energy systems which generate small amounts of energy when compared to traditional centralized power plants. Micro renewable energy systems have now made it possible for home owners to retrofit their premises to generate their own electricity and/or heat, thus becoming more self-sufficient. Allen et al. (2008) references a study where it was predicted that electrical micro renewable energy systems could provide 30–40% of the United Kingdoms’ electricity needs by 2050.

Governments worldwide have included strategies to stimulate the growth of micro renewable …

Alcohol, Self-Regulation, And Partner Physical Aggression: Actor-Partner Effects Over A Three Year Time Frame, Brian M. Quigley, Ash Levitt, Jaye L. Derrick, Maria Testa, Rebecca J. Houston, Kenneth E. Leonard

Articles

The question of how individual differences related to self-regulation interact with alcohol use patterns to predict intimate partner aggression (IPA) is examined. We hypothesized that excessive drinking will be related to partner aggression among those who have low self-regulation. In addition, we explored the extent to which differences in self-regulation in one partner may moderate the relationship between alcohol use and partner aggression. A sample of married or cohabitating community couples (N = 280) ages 18–45 was recruited according to their classification into four drinking groups: heavy drinking in both partners (n = 79), husband only (n = 80), wife …

Teaching And Learning Competencies Valued By Engineering Educators: A Pilot Study, Cormac H. Macmahon, Brian Bowe, Orla Mcconnell, Fiona Cranley

Articles

At the onset of this paper, it is important to provide context by highlighting two backdrop narratives, which have prompted and guided this research project:-(i) Since 2015, The National Forum for the Enhancement of Teaching & Learning in Ireland has undergone an extensive consultation process on professional development, resulting in a guiding document entitled the National Professional Development Framework (NPDF) for Staff Who Teach in Higher Education [1].(ii) The Technological University Alliance for Dublin has placed Dublin Institute of Technology (DIT), Institute of Technology Blanchardstown (ITB) and Institute of Technology Tallaght (ITT) on a merger trajectory towards technological university designation …

Performance Comparison Of Support Vector Machine, Random Forest, And Extreme Learning Machine For Intrusion Detection, Iftikhar Ahmad, Muhammad Javed Iqbal, Mohammad Basheri, Aneel Rahim

Articles

Intrusion detection is a fundamental part of security tools, such as adaptive security appliances, intrusion detection systems, intrusion prevention systems, and firewalls. Various intrusion detection techniques are used, but their performance is an issue. Intrusion detection performance depends on accuracy, which needs to improve to decrease false alarms and to increase the detection rate. To resolve concerns on performance, multilayer perceptron, support vector machine (SVM), and other techniques have been used in recent work. Such techniques indicate limitations and are not efficient for use in large data sets, such as system and network data. The intrusion detection system is used …

Gender In The Context Of Same-Sex Divorce And Relationship Dissolution, Suzanne A. Kim, Edward D. Stein

Articles

This article identifies ways that judges, lawyers, researchers, and policy makers may attend to the role of gender and gender dynamics facing same-sex couples upon divorce or other relationship dissolution. When same-sex couples marry, the legal system and society at large may project conceptions of gender onto same-sex couples, often in a manner that conflicts with couples’ intentions and practices. Gender and gender dynamics may affect the bases for dissolution, the financial aspects of dissolution, and the determination of child custody. The article also suggests directions for future research on the impact of gender on the dissolution of same-sex relationships.

Check Clearing And Voidable Preference Law Under The Bankruptcy Code, David G. Carlson

Articles

Every business practice must withstand the critique of federal voidable preference law. This article surveys how well check clearing system fares under this adjunct to the principle that unsecured creditors should share equally in a bankruptcy proceeding. Check clearing involves extending short-term credit by depositary banks to their customers. Banks routinely extend unsecured and secured credit. The fate of a bank in its customer's bankruptcy differs, depending on what kind of credit is extended. In the case of an overdraft, banks have preference risk, but they also have powerful defenses to muster against liability. In the case credit is advanced …

Maintaining Condominiums And Homeowner Associations: How Much Of A Priority?, Stewart E. Sterk

Articles

During the recent real estate crisis, competition for scarce dollars pitted the holders of defaulted mortgages against condominiums and homeowner associations seeking to collect maintenance assessments. Statutes providing mortgagees with lien priority threatened association ability to provide services, and imposed a disproportionate burden on non-defaulting unit owners. Statutes enacted in other states gave associations a “super priority” lien for six months of assessments, but left uncertainty about the meaning of that super priority in an environment in which foreclosure delays became the norm.

The last five years have brought a spate of litigation over the relative rights of associations and …

Safety Implications Of Plasma-Induced Effects In Living Cells – A Review Of In Vitro And In Vivo Findings, Daniela Boehm, Paula Bourke

Articles

Cold atmospheric plasma is a versatile new tool in the biomedical field with applications ranging from disinfection, wound healing and tissue regeneration to blood coagulation, and cancer treatment. Along with improved insights into the underlying physical, chemical and biological principles, plasma medicine has also made important advances in the introduction into the clinic. However, in the absence of a standard plasma ‘dose’ definition, the diversity of the field poses certain difficulties in terms of comparability of plasma devices, treatment parameters and resulting biological effects, particularly with regards to the question of what constitutes a safe plasma application. Data from various …

An Immodest Proposal For Birth Registration In Donor-Assisted Reproduction, In The Interest Of Science And Human Rights, Elizabeth Samuels

Articles

Increasingly, an individual or a couple raising a newborn child may not be biologically related to the child. The child may be conceived with donated gametes -- a donated egg or sperm or both. A surrogate may gestate the child. The couple may be same-sex. Although we are aware of these developments, we are failing to collect information about them that is vital for medical, public health, and social science research as well as for protecting human rights. Information drawn from birth records is crucial for research, but it is becoming less accurate and less useful as parents who are …

Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, J. J. Prescott

Articles

More than forty U.S. states currently track at least some of their convicted sex offenders using GPS devices. Many offenders will be monitored for life. The burdens and expense of living indefinitely under constant technological monitoring have been well documented, but most commentators have assumed that these burdens were of no constitutional moment because states have characterized such surveillance as ‘‘civil’’ in character—and courts have seemed to agree. In 2015, however, the Supreme Court decided in Grady v. North Carolina that attaching a GPS monitoring device to a person was a Fourth Amendment search, notwithstanding the ostensibly civil character of …

Outcome Prediction In The Practice Of Law, Mark K. Osbeck, Michael Gilliland

Articles

Business forecasters typically use time-series models to predict future demands, the forecasts informing management decision making and guiding organizational planning. But this type of forecasting is merely a subset of the broader field of predictive analytics, models used by data scientists in all manner of applications, including credit approvals, fraud detection, product-purchase and music-listening recommendations, and even the real-time decisions made by self-driving vehicles. The practice of law requires decisions that must be based on predictions of future legal outcomes, and data scientists are now developing forecasting methods to support the process. In this article, Mark Osbeck and Mike Gilliland …

The Institutions Of Innocence Review: A Comparative Sociological Perspective, Jessica A. Roth

Articles

The last three decades have seen the rise of an international innocence movement that has forced participants in diverse criminal justice systems to confront their systems’ fallibility, previously thought more theoretical than real. The public acknowledgment of that fallibility has led to the creation of new institutional mechanisms to re-examine old convictions. This short essay prepared for a symposium issue of the Rutgers University Law Review on the theory of criminal law reform compares the error correction institutions created in the United Kingdom, Canada, and the United States, three English-speaking countries with common law roots and an adversarial structure, through …
