Hybrid Modelling For Stroke Care: Review And Suggestions Of New Approaches For Risk Assessment And Simulation Of Scenarios, Tilda Herrgårdh, Vince I. Madai, John Kelleher, Rasmus Magnusson, Mika Gustafsson, Lili Milani, Peter Gennemark, Gunnar Cedersund

Articles

Stroke is an example of a complex and multi-factorial disease involving multiple organs, timescales, and disease mechanisms. To deal with this complexity, and to realize Precision Medicine of stroke, mathematical models are needed. Such approaches include: 1) machine learning, 2) bioinformatic network models, and 3) mechanistic models. Since these three approaches have complementary strengths and weaknesses, a hybrid modelling approach combining them would be the most beneficial. However, no concrete approach ready to be implemented for a specific disease has been presented to date. In this paper, we both review the strengths and weaknesses of the three approaches, and propose …

In Situ Water Quantification In Natural Deep Eutectic Solvents Using Portable Raman Spectroscopy, Suha Elderderi, Laura Wils, Charlotte Leman-Loubière, Hugh Byrne, Igor Chourpa, Cécile Enguehard-Gueiffier, Emilie Munnier, Abdalla A. Elbashir, Leslie Boudesocque-Delaye, Franck Bonnier

Articles

Raman spectroscopy is a cost-effective, label free and non-destructive analytical tool [1] that delivers specific molecular information to enable the determination of the chemical composition of samples within seconds, with minimum or no requirements for sample preparation. The technique is based on the illumination of samples with a monochromatic laser source, resulting in a fraction of the light being inelastically scattered (the Raman effect) which can be collected as spectral signatures [2]. Raman spectroscopy is considered as an approach well suited for the monitoring and control of chemical and pharmaceutical processes [3,4], end point prediction of chemical synthesis reactions [5] …

Praseodymium Mid-Infrared Emission In Alf3-Based Glass Sensitized By Ytterbium, Jiquan Zhang, Mo Liu, Jin Yu, Ruicong Wang, Shijie Jia, Zijun Liu, Gerald Farrell, Shunbin Wang, Pengfei Wang

Articles

Broadband emission was obtained over 2.6 to 4.1 μm (Pr3+: 1G4→3F4, 3F3) in AlF3-based glass samples doped with different concentrations of praseodymium and 1 mol% ytterbium using a 976 nm laser pump. An efficient energy transfer process from Yb3+: 2F5/2 to Pr3+: 1G4 was analyzed through emission spectra and fluorescence lifetime values. The absorption and emission cross-sections were calculated by Füchtbauer-Ladenburg and McCumber theories and a positive gain can be obtained when P>0.3. To the best of the authors’ knowledge, this work represents the first report of broadband mid-infrared emission of Pr3+ in an AlF3-based glass. The results show …

Social Mobilization In Partisan Spaces, Florian Foos, Peter John, Christian Muller, Kevin Cunningham

Articles

Three decades ago Huckfeldt and Sprague hypothesised that partisan context constrains information sharing between neighbours. We develop their theory to identify implications for campaign mobilisation in homogeneous and mixed-partisan contexts. We argue that GOTV spillover effects should vary with the proportion of rival party supporters in a neighbourhood. Based on two samples of households that were either included or excluded pre-random assignment from a street-level GOTV experiment, we test this expectation of differential spillover effects. We estimate neighbourhood party preferences based on targeting data made available by the UK Labour Party. We find that spillover effects on party supporters are …

An Investigation Into The Food Related Traditions Associated With The Christmas Period In Rural Ireland, Stephanie Byrne, Kathleen Farrell

Articles

The interdisciplinary nature of food studies lends itself to the study of food through many avenues, most notably in this research, through folklore and the oral history transcripts of the Schools’ Collection made by the Irish Folklore Commission in 1937–1938. Folklore can give us an insight into sometimes overlooked features of society and how people’s lives can be studied and highlighted through their relationship with food. The Christmas period was an extremely important time in Irish tradition, and food was a main aspect of that celebration. This paper, therefore, at first delves into the literature surrounding Christmas, folklore, and food; …

Affiliated Issue With 2020 College Art Association Annual Conference, ‘Flesh And Circuit: Rethinking Performance And Technology’ (Chicago, Il, Usa), Conor Mcgarrigle Dr., E.L. Putnam

Articles

The live, embodied, material, and interactive qualities of performance have made it a notable means of exploring the creative potential of technological engagement, acting as a critical vector for revealing and resisting the technological colonisation of everyday life. The innovative collaborations of Experiments in Art and Technology (EAT) during the 1960’s with artists such as Yvonne Rainer and Robert Rauschenberg, Stelarc’s extreme body modifications, Dumb Type’s intermedia performance, and Guillermo Gomez-Pena and La Pocha Nostra’s poetic and speculative imaginings, have mapped the advances in technology and opened new creative fields to explore embodiment. However, there are still some significant oversights …

Articles

ompared with traditional methods for preparing dielectric elastomer (DE) films, electrohydrodynamic (EHD) 3D printing displays many advantages, notably full automation, computer control and flexible design. It also confers high printing resolution, high preparation efficiency with minimal probability of nozzle clogging. In this article, EHD 3D printing was employed to fabricate silicone rubber (SR) based DE films. In order to increase their dielectric constant, high dielectric copper phthalocyanine (CuPc) particles were added into the SR ink. Optimal printing conditions were determined by analyzing the effects of printing voltage and ink properties on the formation of liquid cone and the printed line …

Getting To Know You: An Expanded Approach To Capital Jury Selection, Samuel P. Newton

Articles

The Colorado Method of capital jury selection is a widely embraced strategy defense attorneys use to select jurors during voir dire, in which attorneys rank each juror exclusively on the likelihood that the juror will vote for death. The method could benefit from some expansion. Not all defense lawyers have access to Colorado-Method-based training. In innocence cases, defense lawyers should soften discussions of punishment prior to guilt since this tactic predisposes juries to vote for death. Nor do jurors' views or positions on the death penalty guarantee their eventual votes. While capital juries are already inclined to give death sentences …

A Practice Perspective On Knowledge, Learning And Innovation – Insights From An Eu Network Of Small Food Producers, Clare Rigg, Paul Coughlan, Denise O'Leary, David Coughlan

Articles

Drawing on insider research with a three-year EU network created to support innovation in geographically marginalized traditional food companies, this paper makes three contributions to discussions of innovation in small and micro-firms. First, we shift focus away from conceiving of knowledge as a discrete entity, and of knowledge sharing, transfer and exchange as the passing of objects. Applying a practice perspective that conceptualizes innovation as situated in the everyday activities of organizing, learning and working, we extend open innovation ideas and identify three distinct sets of knowledge-creating practices that small and micro-firm actors in this network context engage in as …

Articles

In this paper, we report on the first project on the promotion of urban geoheritage in Cagliari, the capital of the Autonomous Region of Sardinia (Italy). We briefly address the history of geo-palaeontological research in the city area and outline the main phases of development in the history of Cagliari’s geo-palaeontological museum. Geotourism is an efficient method of bringing geosciences to a wider audience. For this project, we compiled a geoitinerary of the main lithotypes and fossils present within the urban territory. Miocene lithotypes are the most important materials in the edification of the Cagliari’s old town, and in the …

Strain-, Curvature- And Twist-Independent Temperature Sensor Based On A Small Air Core Hollow Core Fiber Structure, Dejun Liu, Wei Li, Qiang Wu, Fengzi Ling, Ke Tian, Changyu Shen, Fangfang Wei, Gerald Farrell, Yuliya Semenova, Pengfei Wang

Articles

Cross-sensitivity (crosstalk) to multiple parameters is a serious but common issue for most sensors and can significantly decrease the usefulness and detection accuracy of sensors. In this work, a high sensitivity temperature sensor based on a small air core (10 µm) hollow core fiber (SACHCF) structure is proposed. Co-excitation of both anti-resonant reflecting optical waveguide (ARROW) and Mach-Zehnder interferometer (MZI) guiding mechanisms in transmission are demonstrated. It is found that the strain sensitivity of the proposed SACHCF structure is decreased over one order of magnitude when a double phase condition (destructive condition of MZI and resonant condition of ARROW) is …

Two-Party Structural Countermandering, Benjamin Plener Cover

Articles

The popular narrative surrounding gerrymandering frames it as a performative phenomenon—achieved through the intentional manipulations of malevolent partisan actors. Efforts to curb partisan gerrymandering —which I call countermandering—have been performative, in turn, focusing on constraining these bad actors through judicial review or mapmaker neutrality. Yet performative countermandering has had limited success. Judicial and institutional constraints are only sometimes available and are often cumbersome and costly. More important, their utility is inherently limited, because gerrymandering is not only performative. It is also structural—an inevitable product of the American electoral schema itself. This paper makes the case for structural countermandering. It explains …

Geographic Gerrymandering, Benjamin Plener Cover

Articles

The leading measures of gerrymandering reflect a party-centric theory of representation based on the statewide relationship between seats and votes. But electoral districting, a traditional practice that still predominates, reflects a geographic theory of representation focused on the district-based relationship between a representative and her constituents. We propose a new approach to gerrymandering that takes electoral districting on its own terms and defines fairness geographically without reference to the seats-votes relationship. Scholars, courts, and mapmakers recognize the representational interests advanced by geographic criteria, such as preservation of local political boundaries. We ask whether an electoral map fairly distributes these benefits. …

Cytotoxic Effects Of 5-Azacytidine On Primary Tumour Cells And Cancer Stem Cells From Oral Squamous Cell Carcinoma: An In Vitro Ftirm Analysis, Valentina Notarstefano, Alessia Belloni, Simona Sabbatini, Chiara Pro, Giulia Orilisi, Riccardo Monterubbianesi, Vincenzo Tosco, Hugh Byrne, Lisa Vaccari, Elisabetta Giorgini

Articles

In the present study, the cytotoxic effects of 5-azacytidine on primary Oral Squamous Cell Carcinoma cells (OSCCs) from human biopsies, and on Cancer Stem Cells (CSCs) from the same samples, were investigated by an in vitro Fourier Transform InfraRed Microscospectroscopy (FTIRM) approach coupled with multivariate analysis. OSCC is an aggressive tumoral lesion of the epithelium, accounting for ~90% of all oral cancers. It is usually diagnosed in advanced stages, and this causes a poor prognosis with low success rates of surgical, as well as radiation and chemotherapy treatments. OSCC is frequently characterised by recurrence after chemotherapy and by the development …

Multicomponent Fokas-Lenells Equations On Hermitian Symmetric Spaces, Vladimir Gerdjikov, Rossen Ivanov

Articles

Multi-component integrable generalizations of the Fokas-Lenells equation, associated with each irreducible Hermitian symmetric space are formulated. Description of the underlying structures associated to the integrability, such as the Lax representation and the bi-Hamiltonian formulation of the equations is provided. Two reductions are considered as well, one of which leads to a nonlocal integrable model. Examples with Hermitian symmetric spaces of all classical series of types A.III, BD.I, C.I and D.III are presented in details, as well as possibilities for further reductions in a general form.

Machine Learning In Sports Medicine: Need For Improvement, Kyle R. Martin, Ayoosh Pareek, Aaron J. Krych

Articles

The over-riding goal of a physician is to optimize the outcome for each individual patient. However, our ability to manipulate the end result at the individual level is limited by our inability to accurately predict the expected outcome of a given clinical scenario. In the age of big data, machine learning can make our predictive capability both easier and more accurate using existing registries and databases which hold the potential to dramatically change decision-making and to optimize individual outcome. The purpose of this editorial was to explore the possible uses of machine learning in sports medicine using existing knee ligament …

Polyesters With Main And Side Chain Phosphoesters As Structural Motives For Biocompatible Electrospun Fibres, André E. Polloni, Viviane Chiaradia, Ronaldo José F.C. Do Amaral, Cathal Kearney, Brian Gorey, Débora De Oliveira, José V. De Oliveira, Pedro H.H. De Araújo, Claudia Sayer, Andreas Heise

Articles

Phosphoester containing polymers are promising materials in biomedical applications due to their biocompatibility and biodegradability. Utilising thiol-ene chemistry, the synthesis of two novel structural polymer motives combining polyesters and phophoester groups was explored. The first polymer was obtained by coupling ene-functional poly(thioether-phosphoester) with thiol functional poly(pentadecalactone). While the coupling reaction was successful, yields remained low presumably due to inadequate endgroup stoichiometry. The second polymer comprised phosphoester side groups conjugated to unsaturated poly(globalide). Double bond conversions up to 84% were achieved depending of the type of phosphoester thiol and relative reactant ratios. The resulting polymers transitioned from solid semicrystaline to liquid …

Novel Coumarin-Thiadiazole Hybrids And Their Cu(Ii) And Zn(Ii) Complexes As Potential Antimicrobial Agents And Acetylcholinesterase Inhibitors, Dariusz Karcz, Karolina Starzak, Ewa Ciszkowicz, Katarzyna Lecka-Szlachta, Daniel Kaminski, Bernadette Creaven, Hollie Jenkins, Piotr Radomski, Anna Miło´S, Lidia Slusarczyk, Arkadiusz Matwijczuk

Articles

A series of coumarin-thiadiazole hybrids and their corresponding Cu(II) and Zn(II) complexes were synthesized and characterized with the use of spectroscopic techniques. The results obtained indicate that all the coumarin-thiadiazole hybrids act as bidentate chelators of Cu(II) and Zn(II) ions. The complexes isolated differ in their ligand:metal ratio depending on the central metal. In most cases, the Zn(II) complexes are characteristic of a 1:1 ligand:metal ratio, while in the Cu(II) complexes the ligand:metal ratio is 2:1. All compounds were tested as potential antibacterial agents against Gram-positive (Staphylococcus aureus, Staphylococcus epidermidis) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa) bacterial strains demonstrating activities …

An Iso/Iec 7816-4 Application Layer Approach To Mitigate Relay Attacks On Near Field Communication, Christina Thorpe, John Tobin, Liam Murphy

Articles

Near Field Communication (NFC) has become prevalent in access control and contactless payment systems, however, there is evidence in the literature to suggest that the technology possesses numerous vulnerabilities. Contactless bank cards are becoming commonplace in society; while there are many benefits from the use of contactless payments, there are also security issues present that could be exploited by a malicious third party. The inherently short operating distance of NFC (typically about 4 cm) is often relied upon as a means of ensuring intentional interaction on the user’s part and limiting attack vectors. However, NFC is particularly sensitive to relay …

Optimisation Of Retrofit Wall Insulation: An Irish Case Study, Rakshit D. Muddu, D M. Gowda, Anthony James Robinson, Aimee Byrne

Articles

Ireland has one of the highest rates of emissions per capita in the world and its residential sector is responsible for approximately 10% of total national CO2 emissions. Therefore, reducing the CO2 emissions in this sector will play a decisive role in achieving EU targets of reducing emissions by 40% by 2030. To better inform decisions regarding retrofit of the existing building stock, this study proposes Optimum Insulation Thicknesses (OIT) for typical walls in 25 regions in Ireland. The calculation of OIT includes annual heat energy expenditure, CO2 emissions, and material payback period. The approach taken is based on Heating …
