Articles

A platinum coated singlemode-multimode (SM) structure is investigated in this paper as an optical fibre sensor (OFS) to monitor the phase transition of a phase change material (PCM). Paraffin wax has been used as an example to demonstrate the sensor's performance and operation. Most materials have the same temperature but different thermal energy levels during the phase change process, therefore, sole dependency on temperature measurement may lead to an incorrect estimation of the stored energy in PCM. The output spectrum of the reflected light from the OFS is very sensitive to the bend introduced by the PCM where both liquid …

A Comprehensive Experimental Study Of Whispering Gallery Modes In A Cylindrical Micro-Resonator Excited By A Tilted Fiber Taper, Vishnu Kavungal, Gerald Farrell, Qiang Wu, Arun Mallik, Yuliya Semenova

Articles

Whispering gallery modes (WGMs) excitation in a cylindrical microresonator formed by a section of silica optical fiber has been studied. Evanescent light coupling into the microresonator is realized using a tapered optical fiber, fabricated by a microheater brushing technique. Several types of silica fibers with different diameters are studied as microresonators, and the influence of the resonator's diameter on the excitation of WGMs is investigated. The excitation of WGMs in a cylindrical fiber resonator were studied with changes to the tilt angle between the microcylinder and the fiber taper in the range of angles from a perpendicular position (0 degrees) …

Formation And Development Of Nanometer-Sized Cybotactic Clusters In Bent-Core Nematic Liquid Crystalline Compounds, Yuri Panarin, Sithara P. Sreenilayam, Jagdish K. Vij, Anne Lehmann, Carsten Tschierske

Articles

Two homologue achiral bent-core liquid crystals (LCs), BCN66 and BCN84, in their nematic phases are studied by dielectric spectroscopy in the frequency range 10 Hz–10 MHz. In each of these compounds, two relaxation processes are identified and assigned to (i) collective dynamics of molecules in nanometer-sized cybotactic clusters and (ii) individual molecular relaxations, in the ascending order of frequency of the probe field. The temperature and the bias electric field dependence of the dielectric strength and relaxation frequency for these processes are shown to give rise to sharpness in cluster boundaries, increased size and volume fraction in the LC nematic …

Optical Fiber Fresnel Reflection Sensor For Direct Detection Of The Solid-Liquid Phase Change In N-Octadecane, Wei Han, Marek Rebow, Dejun Liu, Gerald Farrell, Yuliya Semenova, Qiang Wu

Articles

An all optical fiber Fresnel reflection sensor for detecting the solid–liquid phase change in n-octadecane is proposed and experimentally demonstrated. The sensor probe consists of a single-mode fiber with a cleaved end which is immersed in the material sample under test. As the n-octadecane changes from solid to liquid or from liquid to solid, its refractive index (RI) changes resulting in changes of the light power ratio reflected by the probe. Since the RI of n-octadecane during its phase transition changes discontinuously, inflection in the reflected light power ratio dependence indicates the phase change of the sample in the vicinity …

The Role Of The Dendritic Growth Models Dimensionality In Predicting The Columnar To Equiaxed Transition (Cet), M. Seredyński, Marek Rebow, J. Banaszek

Articles

The dendrite tip kinetics model accuracy relies on the reliability of the stability constant used, which is usually experimentally determined for 3D situations and applied to 2D models. The paper reports authors` attempts to cure the situation by deriving 2D dendritic tip scaling parameter for aluminium-based alloy: Al-4wt%Cu. The obtained parameter is then incorporated into the KGT dendritic growth model in order to compare it with the original 3D KGT counterpart and to derive two-dimensional and three-dimensional versions of the modified Hunt’s analytical model for the columnar-to-equiaxed transition (CET). The conclusions drawn from the above analysis are further confirmed through …

An Lcl-Filter Design With Optimum Total Inductance And Capacitance, Sampath Jayalath, Mohamed Moin Hanif

Articles

LCL-filter is among the best performing filters for grid-connected voltage source inverters. Designing of the filter parameters (grid-side and inverter-side inductors and capacitor), takes an iterative approach due to the coherence between the parameters and design requirements such as IEEE-519 Std for harmonic current limitations, reactive power compensation limit, and maximum allowable voltage drop across the filter to limit the switching losses. Most of the proposed LCL-filter optimization strategies emphasize on reducing the total inductance and losses of the filter while meeting the design requirements. There is less emphasis given on the capacitor selection and optimizing its value. Therefore, this …

Sarcopenia During Neoadjuvant Therapy For Oesophageal Cancer: Characterising The Impact On Muscle Strength And Physical Performance, E.M. Guinan, Suzanne Doyle, A.E. Bennett, L. O'Neill, J. Gannon, J.A. Elliott, J. O'Sullivan, J.V. Reynolds, J. Hussey

Articles

Purpose Preoperative chemo(radio)therapy for oesophageal cancer (OC) may have an attritional impact on body composition and functional status, impacting postoperative outcome. Physical decline with skeletal muscle loss has not been previously characterised in OC and may be amenable to physical rehabilitation. This study characterises skeletal muscle mass and physical performance from diagnosis to post-neoadjuvant therapy in patients undergoing preoperative chemo(radio)therapy for OC.

Methods Measures of body composition (axial computerised tomography), muscle strength (handgrip), functional capacity (walking distance), anthropometry (weight, height and waist circumference), physical activity, quality-of-life and nutritional status were captured prospectively. Sarcopenia status was defined as pre-sarcopenic (low muscle …

Lessons From Case Study Of Secured Transactions With Bitcoin, Xuan-Thao Nguyen

Articles

There has been some discussion about the flaws in using secured transactions law, Article 9 of the Uniform Commercial Code (U.C.C.), to govern commercial transactions involving Bitcoins as collateral. Flaws necessitate the urgency of immediately fixing of the existing law. In the case of Bitcoins there is still much to learn about the marketplace for secured transactions with Bitcoins as collateral. The rapid change in technology, the speed of new ideas proposed, the constant announcements of adoption and adaptation of smart contracts in transactions, the volatility in cryptocurrency value, the endless reports of scams, and the rise of dark pools …

Patent Aversion: An Empirical Study Of Patents Collateral In Bank Lending, Xuan-Thao Nguyen, Erik Hille

Articles

The most valuable assets of many companies today are patents. If patents are valuable, why do banks operating across the United States refuse to lend against patents in commercial lending to reduce their risks? Lending is the primary function of banks. Yet banks have a strong aversion to accept patents as collateral, rendering the vast number of patents as idle assets. This empirical study is the first to identify the patent aversion problem as contrary to the frequent headlines of how valuable patents are to the economy. By carefully extracting relevant patent and security interest filings data and examining the …

A Long-Standing Debate: Reflections On Risk And Anxiety: A Theory Of Data Breach Harms By Daniel Solove And Danielle Keats Citron, Ryan Calo

Articles

This jointly-authored Article contributes mightily to our understanding of a critical aspect of privacy: harm. As Professors Solove and Citron carefully evidence, courts are reticent to countenance the harms that flow from a violation of privacy, even as they compensate similar harms in other contexts. Thus while exposing a plaintiff to an environmental or health risk may be compensable, few decisions vindicate victims of a data breach unless or until they experience actual identity theft. Courts have recognized subjective harms such as fear since the night W de S threw his fateful axe at M de S. But courts seldom …

Visual Rulemaking, Elizabeth G. Porter, Kathryn A. Watts

Articles

Visual politics are seeping into the technocracy. Rulemaking stakeholders—including agencies, the President, and members of the public—are deploying politically tinged visuals to push their agendas at every stage of high-stakes, often virulently controversial, rulemakings. These images, GIFs, and videos usually do not make it into the official rulemaking record, so this new “visual rulemaking” world has not been discussed much by scholars or others.

In this article, we explore the new visual rulemaking culture that emerged in Obama’s presidency, providing examples and discussing relevant policy implications. Although we recognize some risks, we argue that, on balance, visual rulemaking is a …

Amending Codes Of Judicial Conduct To Impose Campaign Contribution And Expenditure Limits On Judicial Campaigns, Hugh D. Spitzer, Philip A. Talmadge

Articles

Every judicial campaign year, millions of dollars pour into individual court races around the country. The bulk of that money is donated by lawyers, businesses, and others with financial interests in how judges, especially appellate judges, decide cases. United States Supreme Court rulings on political contributions and spending have hamstrung the ability of states to control larges-cale expenditures in judicial races. This essay reviews empirical research by political scientists who have documented the effect of large campaign donations on how judges decide cases and on the public's perception of court impartiality. It describes how legislatures and courts have addressed (or …

Shipping Company Ordered To Pay Almost $1m For Demoting Whistleblower, Craig H. Allen

Articles

The US Department of Labor's (DOL) Administrative Review Board recently affirmed a DOL administrative law judge (ALJ) decision in favor of the former master of the Horizon Trader who had filed a complaint alleging that the Horizon violated the Seaman's Protection Act by discharging him in retaliation for making protected safety reports to the US Coast Guard and American Bureau of Shipping. In Loftus v. Horizon Lines, Inc. (DOL ARB Case No. 16-082), the board upheld the ALJ's award of $655,1998.90 in back pay plus interest; $10,000 in compensatory damages for emotional distress; $225,000 in punitive damages, and an unspecified …

Catching Disruption: Regulating Corporate Venture Capital, Jennifer S. Fan

Articles

Sesame Street, Walgreens, 7-Eleven, General Motors, Campbell Soup—these are not the names of companies that come to mind when thinking about the startup world. Yet, each of these companies started its own corporate venture capital arm in the last eight years. Corporate venture capital (“CVC”)—equity investments in external startups made by corporations or investment entities designated by corporations—no longer play a minor role in venture capital: they have become an influential force in the field. Business scholars have been at the forefront of studying this newly powerful phenomenon. Thus far, however, legal scholars have overlooked CVCs. Legal scholars—and many in …

Democratizing Proof: Pooling Public And Police Body-Camera Videos, Mary D. Fan

Articles

There are two cultural revolutions in recording the police. From the vantage of police departments, there is the rapidly spreading uptake of police-worn body cameras. On the public side, community members are increasingly using their cell phone cameras to record the police. Together, these dual recording revolutions are generating important new questions and possibilities regarding the balance of power in producing proof and illuminating contested encounters. This Essay is about how pooling police body camera and public videos can address three emerging challenges in the police recording revolution. The first challenge is the controversy over failures to record contested encounters …

“And Yet It Moves”—The First Amendment And Certainty, Ronald K.L. Collins

Articles

Surprisingly few, if any, works on the First Amendment have explored the relation between free speech and certainty. The same holds true for decisional law. While this relationship is inherent in much free speech theory and doctrine, its treatment has nonetheless been rather opaque. In what follows, the author teases out— philosophically, textually, and operationally—the significance of that relationship and what it means for our First Amendment jurisprudence. In the process, he examines how the First Amendment operates to counter claims of certainty and likewise how it is employed to demand a degree of certainty from those who wish to …

The Flipside Of Michigan V. Epa: Are Cumulative Impacts Centrally Relevant?, Sanne H. Knudsen

Articles

This Article explores the flipside of Michigan--where the Court's logic can just as well support agencies in their public health and environmental protection efforts. In particular, taking Michigan as a blueprint, this Article argues that cumulative impacts are centrally relevant to environmental regulation and--like cost--deserve a systemic and meaningful role in agency decisionmaking, including in the threshold decision of when to regulate.

In doing so, this Article serves as a counterbalance to the weight of cost benefit rhetoric that would reduce environmental law off to a line item in a strained budget. In support of that thesis, this Article …

Socioeconomic Status Discrimination, Danieli Evans

Articles

This Article makes the case for protecting socioeconomic status (SES) under discrimination statutes that govern employment, housing, education, voting, public accommodations, and credit/lending. While others have argued that poverty should be a protected class under the Fourteenth Amendment, the courts have rejected this idea. The possibility of protecting SES under discrimination statutes has received little consideration. I argue that this idea deserves more serious attention. I advance four arguments in favor of adding SES to the list of protected traits. Two moral, one political, and one legal.

First and most straightforward, the values animating discrimination law apply to poverty: Existing …

Work Only We Can Do: Professional Responsibility In An Age Of Automation, Sherman J. Clark

Articles

Automation can help us do our work as lawyers; but in the process, it should also force us to be more thoughtful about what our work really is or ought to be.' The challenge for the profession, as I see it, is not simply to survive the advent of new technology, nor even merely to make effective use of new tools. While addressing those immediate concerns, we should also welcome the concomitant opportunity to develop and refine our understanding of what it means to be a good and ethical lawyer. As technological developments free us from and prevent us from …

Sodium Caprate Enables The Blood Pressure-Lowering Effect Of Ile- Pro-Pro And Leu-Lys-Pro In Spontaneously Hypertensive Rats By Indirectly Overcoming Pept1 Inhibition, John Gleeson, Jesus Maria Frias, Sinead Ryan, David J. Braydon

Articles

The tripeptides, Ile-Pro-Pro (IPP) and Leu-Lys-Pro (LKP), inhibit angiotensin-converting enzyme (ACE) resulting in lowered blood pressure. Our hypothesis was that the medium chain fatty acid permeation enhancer, sodium caprate (C10), may prevent the decrease in permeability of the tripeptides when PepT1 is inhibited by glycyl-sarcosine (Gly-Sar), a situation that may occur in the presence of food hydrolysates. Using Caco-2 monolayers and isolated rat jejunal tissue, the apparent permeability coefficients (Papp) of [3H]-IPP and [3H]- LKP were assessed in the presence of Gly-Sar with and without C10. Gly-Sar decreased the Papp of both tripeptides across monolayers and isolated jejunal tissue, but …

Articles

Infectious diseases remain one of the leading causes of morbidity and mortality worldwide. The WHO and CDC have expressed serious concern regarding the continued increase in the development of multidrug resistance among bacteria. Therefore, the antibiotic resistance crisis is one of the most pressing issues in global public health. Associated with the rise in antibiotic resistance is the lack of new antimicrobials. This has triggered initiatives worldwide to develop novel and more effective antimicrobial compounds as well as to develop novel delivery and targeting strategies. Bacteria have developed many ways by which they become resistant to antimicrobials. Among those are …

Impact Of Plasma Jet Geometry On Residence Times Of Radical Species, James Lalor, Laurence Scally, Patrick J. Cullen, Vladimir Milosavljevic

Articles

Numerous electrode geometries and power supplies, both commercial and in-house, have been employed for the generation of low-temperature atmospheric plasma jets. In this work, the development and operation of a 12 jet nonthermal atmospheric plasma system is presented. The study is based on optical spectroscopy as a diagnostic method due to its nonintrusive nature. A key focus of this study was the material selection (conductive and nonconductive), with several polymers screened for the jet design leading to polyacetal as the choice material. Their results are compared with other atmospheric plasma jet systems. The results show a significant increase in residence …

The Effects Of Varying Gas Concentrations And Exposure Times On Colour Stability And Shelf-Life Of Vacuum Packaged Beef Steaks Subjected To Carbon Monoxide Pretreatment, Lauren Anne Van Rooyen, Paul Allen, Caragh Kelly-Rees, David I. O'Connor

Articles

There is an emerging demand for more value-added meat packaging technologies which enhance meat quality. Overall, colour is the most important quality trait judged at point of purchase as sensory traits cannot be physically assessed prior to consumption (Carpenter, Cornforth, & Whittier, 2001; Van Rooyen, Allen, Crawley, & O’Connor, 2017). Consumers use colour as an indicator of freshness and wholesomeness and this influences perceived meat quality (Carpenter et al., 2001; Issanchou, 1996), while discoloration is associated with unwholesomeness (Faustman & Cassens, 1990) and leads to economic losses (Kropf, Hunt, & Piske, 1986) and food waste. Packaging directly affects the colour …
