PLANCK-HFI : Performances of an optical concept for the cosmic microwave background anisotropies measurement
(2004)
Brossard, J.; Yurchenko, V.; Gleeson, E.; Longval, Y.; Maffei, B.; Murphy, J.Anthony; Ristorcelli, I.; Lamarre, J.-M.
Abstract:
PLANCK is a project of the European Space Agency to be launched in February 2007 by an Ariane V rocket with the Herschel Space Observatory. It is designed for imaging the temperature and polarization anisotropies of the millimetre and sub-millimetre radiation over the whole sky with unprecedented sensitivity, accuracy and angular resolution using 9 frequency channels ranging between 25 and 1000 GHz. The main source at these frequencies is the Cosmic Microwave Background (CMB), i.e. the radiation emitted by the early universe when, about 300000 years old, ionised hydrogen recombined and became transparent from the visible to radio frequencies of the electromagnetic spectrum. The main goal of the PLANCK mission is to retrieve the main cosmological parameters of the Universe with accuracies of a few percent from the observation and analysis of random small contrast (10-4) features in the CMB. The angular power spectrum of the CMB anisotropies is a function of the fundamental cosmologic...

Gaussian Fitting Parameters of the ESA PLANCK HFI Beams
(2004)
Yurchenko, V.; Murphy, J.Anthony; Lamarre, J.-M.; Brossard, J.
Abstract:
We present Gaussian fitting parameters of simulated beams of the High Frequency Instrument (HFI) of the ESA PLANCK mission. This space probe is designed for measuring the anisotropy of temperature and polarization of the Cosmic Microwave Background (CMB). The six HFI spectral bands cover the frequency range 0.1 - 1 THz with 52 bolometers. Their beams are computed by multi-mode physical optics propagation of the source field from the apertures of the horns simulated by the scattering matrix approach. Computed power patterns are fitted by the elliptical Gaussian beams minimizing the peak difference between the two power distributions within the beam. This approximation is generally considered as acceptable from the scientific viewpoint, although we show that induced errors are far from negligible.

How skilful are US fixed-income fund managers?
(2021)
Clare, Andrew; Cuthbertson, Keith; Nitzsche, Dirk; O'Sullivan, Niall
Abstract:
We develop a performance evaluation model that incorporates the factors proposed by Huij and Derwall (2008) and a fund-specific benchmark to analyse the performance of US fixed income funds. Using the full sample, and accounting for the possibility of false discoveries, we find that fund management companies extract most of any abnormal performance produced by their fund managers. Our sub-sample analysis indicates that after the Global Financial Crisis (GFC) there was a substantial increase in the number of bond funds with: both positive gross-of-fee alpha and positive net-of-fee alpha performance; and also a reduction in funds with negative-alpha performance. However, because the GFC was such a unique event, it would still be difficult to conclude that these managers offer value for money for investors compared to passive alternatives.

The effects of sequential heat treatment on microbial reduction and spore inactivation during milk processing
(2021)
Li, Fang; Hunt, Karen; Buggy, Aoife K.; Murphy, Kevin; Ho, Quang Tri; O'Callaghan, Tom; Butler, Francis; Jordan, Kieran; Tobin, John
Abstract:
Sequential heating processes are commonly applied to milk by the dairy industry as part of their microbiological control strategy. Often pasteurisation at 72 °C is followed by a sequential high heat treatment step of up to 125 °C; however, such severe heat treatment can lead to reduced protein quality. Nine temperature combinations (80–90 °C) were evaluated to assess microbial reduction and whey protein nitrogen index values during pilot scale milk processing. A total of 110 bacterial isolates were identified to species level by 16S rDNA sequencing, with Bacillus licheniformis identified as the dominant species. While the experimental treatments did not achieve microbial reductions comparable with the control heating process, the results of this study provide a benchmark for milk processors relative to the effects of sequential heat treatments on milk and their impact on the survival of both thermally resistant microbial populations and thermally labile milk components during proces...

Evolution of the bovine milk fatty acid profile – From colostrum to milk five days post parturition
(2021)
O'Callaghan, Tom; O'Donovan, Michael; Murphy, John; Sugrue, Katie; Mannion, David; McCarthy, William P.; Timlin, Mark; Kilcawley, Kieran; Hickey, Rita M.; Tobin, John T.
Abstract:
Milk was collected from each of 18 cows (presenting an even spread of 1st, 2nd and 3rd lactation): colostrum on the day of calving and subsequent morning milk 1–5 days post parturition. Days post parturition significantly affected the fatty acid profile of colostrum and transition milk samples. The colostrum fatty acid profile was distinctly different from that of mature milk, with significantly higher levels of polyunsaturated and saturated fatty acids. Parity of the cow had a significant effect on the fatty acid profile of colostrum and transition milk samples; conjugated linoleic acid was significantly higher in cows entering their 1st lactation than in those in their 3rd lactation, while multiparous cows produced significantly higher concentrations of C16:0. The changing composition of the fatty acid profile can be classed into three distinct phases: colostrum (D0), transition milk (D1 and D2 post parturition) and mature milk (D3–D5).

Kumar, Ajay; Ramisetty, Kiran A.; Bordignon, Simone; Hodnett, Benjamin K.; Davern, Peter; Hudson, Sarah
Abstract:
This work investigated the technical feasibility of preparing, stabilizing and isolating poorly water-soluble drug nanoparticles via a small-scale antisolvent precipitation process operating in semi-continuous mode. Specifically, a novel semi-continuous process was demonstrated for the carrier particle mediated production, stabilization and isolation of valsartan nanoparticles into a solid form using montmorillonite clay particles as the carrier. The semi continuous process operated robustly for the full duration of the experiment (~16 min) and steady-state conditions were reached after ~5 min. Nanoparticles of valsartan (51 ± 1 nm) were successfully prepared, stabilized and isolated with the help of montmorillonite (MMT) or protamine functionalized montmorillonite (PA-MMT) into the dried form by this semi-continuous route. The dissolution profile of the isolated valsartan nanocomposite solids was similar to that of valsartan nanocomposite solids produced via the corresponding labor...

Putting the fox in charge? Political parties and the GDPR: An Irish perspective
(2020)
McDonagh, Maeve; Donnelly, Mary
Abstract:
In the wake of Cambridge Analytica, the use of personal data by political parties has been subject to increased scrutiny. Given the specific policy challenges which such use poses, this article examines the conditions for the lawful processing of personal data under the General Data Protection Regulation (GDPR), as it applies to political parties. It identifies the extensive flexibilities afforded by the GDPR to Member States and argues that granular Member State analysis is required if the GDPR regime is to be meaningfully evaluated in this context. Using Ireland as a detailed case study and referencing the equivalent provisions of the UK Data Protection Act 2018 (DPA UK) for comparison, the article examines the different ways in which these Member States responded to the flexibility afforded by the GDPR. Based on this, the article argues that closer engagement with the issue of political parties by the European Data Protection Board is needed in order to provide a more fine-graine...

A comparison between predictive modelling approaches for spirally reinforced composite catheter tubing using classical statistical DOE and a custom DOE design
(2020)
Lynn, Sean; Tanner, David A.; Ryan, Alan; O'Malley, Philip; Moore, Sean
Abstract:
The Medical Device industry lags other industries such as automotive and aerospace in terms of the use of predictive modeling as a design tool. This has started to change with growing experience being established with metal scaffold type structures (stents, Transcatheter aortic valve structures etc.). However, these computational methods are generally used with structures that are composed of a single material type as with Finite Element Analysis (FEA). Composite interventional catheters generally features 3-layer composite structures (polymer layer A/Metal reinforcement layer B/polymer layer C) which offer different challenges than single material structures in terms of predictive modeling. The results achieved with two different Experimental Design or Design of Experiments (DOE) based predictive modeling methodologies will be compared. The Classic DOE approach is based on a full factorial DOE with center points. The Custom DOE approach is based on the full factorial approach but i...

Dynamic in situ imaging of semi-hard cheese microstructure under large-strain tensile deformation: Understanding structure-fracture relationships
(2021)
Lamichhane, Prabin; Auty, Mark A.E.; Kelly, Alan L.; Sheehan, Diarmuid (JJ)
Abstract:
Changes in the microstructure of semi-hard cheeses were observed in situ under tensile deformation by placing a microtensile stage directly under a confocal scanning laser microscope, and recording force/displacement data simultaneously. On tensile deformation, detachment of fat globules and their subsequent release from the cheese matrix were observed, suggesting that they are weakly bonded to or entrapped within the cheese matrix. Moreover, an inherent micro-defect was observed at a curd granule junction within the cheese matrix, which fractured along the curd granule junction under tensile deformation, suggesting that such micro-defects could be a key to the formation of undesirable slits or cracks. Furthermore, the fracture behaviour of semi-hard cheese varied with ripening temperature, coagulant type, and inhibition of residual chymosin activity. Overall, this study demonstrated the potential of dynamic in situ imaging of cheese microstructure for developing a greater understan...

Review of near-infrared spectroscopy as a process analytical technology for real-time product monitoring in dairy processing
(2021)
Pu, Yuan-Yuan; O'Donnell, Colm; Tobin, John T.; O'Shea, Norah
Abstract:
Real-time process/product monitoring can be achieved using suitable process analytical technologies (PAT) to improve process efficiencies and product quality. In the dairy industry, near infrared (NIR) spectroscopy has been utilised as a laboratory analytical method (off-line) for compositional analysis of dairy products since the 1970s. Recent advances in NIR technology and instrumentation have widened its applications from a bench-top analytical instrument to a promising PAT tool for on-line and in-line implementation. This review focuses on the use of NIR technology for real-time monitoring of dairy products, by briefly outlining the measurement principle, NIR instrument configurations, in-line sampling methods, calibration models development, some practical considerations for process installation, and current state of the art in on-line and in-line NIR applications (2012 to date) for continuous process monitoring in the production of dairy products. The challenges and additional...

Influence of sodium hexametaphosphate addition on the functional properties of milk protein concentrate solutions containing transglutaminase cross-linked proteins
(2021)
Power, Orla M.; Fenelon, Mark; O'Mahony, James A.; McCarthy, Noel
Abstract:
The functional properties of milk protein concentrate (MPC) powders are often hindered by their poor solubility. Calcium chelating salts have been shown to improve powder solubility, but generally their action contributes to higher viscosity due to disintegration of casein micelles and higher levels of serum-phase calcium. To help mitigate increases in viscosity associated with calcium chelation, transglutaminase (TGase), an enzyme that covalently crosslinks protein, was employed in an effort to stabilise the casein micelle structure. Sodium hexametaphosphate (SHMP) was added to control (C-MPC) and TGase crosslinked MPC (TG-MPC) dispersions at concentrations of 5, 12.5 and 25 mm prior to analysis. TG-MPC dispersions had lower viscosity than C-MPC dispersions across all SHMP concentrations studied. Crosslinking limited micelle dissociation on SHMP addition and led to greater retention of the white colour of the protein dispersions, while the turbidity of C-MPC dispersions decreased w...

Establishing nationally representative benchmarks of farm-gate nitrogen and phosphorus balances and use efficiencies on Irish farms to encourage improvements
(2021)
Thomas, I.A.; Buckley, C.; Kelly, E.; Dillon, E.; Lynch, J.; Moran, B.; Hennessy, T.; Murphy, P.N.C.
Abstract:
Agriculture faces considerable challenges of achieving more sustainable production that minimises nitrogen (N) and phosphorus (P) losses and meets international obligations for water quality and greenhouse gas emissions. This must involve reducing nutrient balance (NB) surpluses and increasing nutrient use efficiencies (NUEs), which could also improve farm profitability (a win-win). To set targets and motivate improvements in Ireland, nationally representative benchmarks were established for different farm categories (sector, soil group and production intensity). Annual farm-gate NBs (kg ha−1) and NUEs (%) for N and P were calculated for 1446 nationally representative farms from 2008 to 2015 using import and export data collected by the Teagasc National Farm Survey (part of the EU Farm Accountancy Data Network). Benchmarks for each category were established using quantile regression analysis and percentile rankings to identify farms with the lowest NB surplus per production intensit...

Reviving Rylands: how the doctrine could be used to claim compensation for environmental damages caused by fracking
(2014)
Costello, Róisín Áine
Abstract:
Contemporary societies are characterized by complex interdependence, with industrial activity increasingly having the potential to cause effects beyond local and national borders. Courts have previously illustrated that liability for injurious action must lie with the individual who created the risk of damage under the common law rule of Rylands v. Fletcher. Having fallen out of favour in the twentieth century, this article pro- poses a re-articulation of the rule to cover situations in modern society in which invasive methods are used in the extraction of volatile fuels from the earth, specifically in the case of ‘fracking’. The article examines recent rulings from the United States and the United Kingdom, as well as precedent from the United Kingdom and Ireland to establish the manner in which the rule of Rylands v. Fletcher might be successfully rearticulated in the context of contemporary common law jurisdictions – specifically focusing on Ireland – as a means for redressing env...

Schrems II: everything is illuminated?
(2020)
Costello, Róisín Áine
Abstract:
The decision in Schrems II delivered by the Court of Justice in July 2020 (judgment of 16 July 2020, case C-311/18, Data Protection Commissioner v. Facebook Ireland Ltd and Maximillian Schrems) was, in many ways, foreseeable given the scheme and recent history of the Union’s privacy and data protection jurisprudence. Despite this, the decision has significant and far-reaching implications both for the protective standards afforded to personal data which are the subject of international data transfers and the role and responsibilities of data controllers where such transfers take place. More fundamentally, the decision also raises a series of further questions about the scope and reach of European data protection standards, the interpretation of the general Data Protection Regulation (GDPR) and the prospects of the United Kingdom in seeking an adequacy decision as a third country following Brexit.

Artificial intelligence: a threat to strategic stability
(2020)
Johnson, James
Abstract:
AI-augmented conventional capabilities might affect strategic stability between great military powers. The nuanced, multifaceted possible intersections of this emerging technology with a range of advanced conventional weapons can compromise nuclear capabilities, thus amplifying the potentially destabilizing effects of these weapons. This article argues that a new generation of artificial intelligence—enhanced conventional capabilities will exacerbate the risk of inadvertent escalation caused by the commingling nuclear and nonnuclear weapons. The increasing speed of warfare will also undermine strategic stability and increase the risk of nuclear confrontation.

Artificial intelligence: drone swarming and escalation risks in future warfare
(2020)
Johnson, James
Abstract:
The rapid proliferation of a new generation of artificial intelligence (AI)-augmented and -enabled autonomous weapon systems (AWS), most notably drones used in swarming tactics, could have a significant impact on deterrence, nuclear security, escalation and strategic stability in future warfare. James Johnson argues that emerging iterations of AWS fused with AI systems will presage a powerful interplay of increased range, accuracy, mass, coordination, intelligence and speed in a future conflict. In turn, the risk of escalatory use-them-or-lose-them situations between nuclear-armed military powers and the attendant dangers posed by the use of unreliable, unverified and unsafe AWS will increase, with potentially catastrophic strategic outcomes.

Abstract:
Despite strong selection for athletic traits in Thoroughbred horses, there is marked variation in speed and aptitude for racing performance within the breed. Using global positioning system monitoring during exercise training, we measured speed variables and temporal changes in speed with age to derive phenotypes for GWAS. The aim of the study was to test the hypothesis that genetic variation contributes to variation in end‐point physiological traits, in this case galloping speed measured during field exercise tests. Standardisation of field‐measured phenotypes was attempted by assessing horses exercised on the same gallop track and managed under similar conditions by a single trainer. PCA of six key speed indices captured 73.9% of the variation with principal component 1 (PC1). Verifying the utility of the phenotype, we observed that PC1 (median) in 2‐year‐old horses was significantly different among elite, non‐elite and unraced horses (P < 0.001) and the temporal change with ag...

Locative reverb: Artistic practice, sound technology, and the grammatization of the listener in the city
(2021)
Putnam, El
Abstract:
There are various ways that artists use technology in exploring the relation of sound to the urban environment, which has different impacts on the listener in relation to place. The rising prominence of these works is connected to a broader sonic turn in urban studies and art, underscoring a rising emphasis on the influence of sound on multisensory experience. Using Bernard Stiegler’s consideration of technology as pharmakon (or the condition of duality in which something is both poison and cure, bringing both benefit and harm), and his definition of technological grammatization, how artistic use of technology mediates the relationship of the urban environment to the listener through sound is studied through a pharmacological approach in order to nuance the possibilities of artistic critical engagement, emphasising how this can include unintended consequences of re-enforcing certain listener behaviours. At the same time, considerations of how artistic repurposing of listening techno...

Delegating strategic decision-making to machines: Dr. Strangelove redux?
(2020)
Johnson, James
Abstract:
Will the use of artificial intelligence (AI) in strategic decision-making be stabilizing or destabilizing? What are the risks and trade-offs of pre-delegating military force (or automating escalation) to machines? How might non-nuclear state and non-state actors leverage AI to put pressure on nuclear states? This article analyzes the impact of strategic stability of the use of AI in the strategic decision-making process, in particular, the risks and trade-offs of pre-delegating military force (or automating escalation) to machines. It argues that AI-enabled decision support tools, by substituting the role of human critical thinking, empathy, creativity, and intuition in the strategic decision-making process, will be fundamentally destabilizing if defense planners come to view AI’s ‘support’ function as a panacea for the cognitive fallibilities and human analysis and decision-making. The article also considers the nefarious use of AI-enhanced fake news, deepfakes, bots, and other for...

Artificial intelligence in nuclear warfare: a perfect storm of instability?

Artificial intelligence in nuclear warfare: a perfect storm of instability?
(2020)
Johnson, James
Abstract:
A significant gap exists between the expectations and fears of public opinion, policymakers, and global defense communities about artificial intelligence (AI) and its actual military capabilities, particularly in the nuclear sphere. The misconceptions that exist today are largely caused by the hyperbolic depictions of AI in popular culture and science fiction, most prominently the Skynet system in The Terminator. Misrepresentations of the potential opportunities and risks in the military sphere (or “military AI”) can obscure constructive and crucial debate on these topics—specifically, the challenge of balancing the potential operational, tactical, and strategic benefits of leveraging AI, while managing the risks posed to stability and nuclear security. This article demystifies the hype surrounding AI in the context of nuclear weapons and, more broadly, future warfare. Specifically, it highlights the potential, multifaceted intersections of this disruptive technology with nuclear s...

Indian approaches to security and conflict resolution
(2019)
Doyle, John
Abstract:
This article analyses the inter-relationships between India’s approach to conflict resolution at the global, regional and domestic levels, with a view to clarifying the most consistent positions of the Indian state. At the global level, while there have been some strategic silences reflecting realpolitik, India remains a strong support of UN peacekeeping and critical of armed intervention for humanitarian purposes. At a regional level traditional security approaches dominate. There is a rhetorical commitment to regional integration as a means of building better relationships with neighbours, but India’s actions reflect a model of security and conflict resolution based on deterrence and military power-projection. At the domestic level India has a long tradition of managing internal conflicts through state formation and elite co-option. However, in the North East and in particular in Kashmir and in the Maoist conflicts there have been missed opportunities to de-escalate, when the posi...

Who produced this video, amateur or professional?

Guo, Jinlin; Gurrin, Cathal; Lao, Song-Yang
Abstract:
As the increasing affordability for capturing and storing video and the proliferation of Web 2.0 applications, video content is no longer necessarily created and supplied by a limited number of professional producers; any amateur can produce and publish his/her video quickly. Therefore, the amount of both professional-produced as well as amateur-produced video on the web is ever increasing. In this work, we propose a question; whether we can automatically classify an Internet video clip as being either professional-produced or amateur-produced? Hence, we investigate features and classification methods to answer this question. Based on the differences in the production processes of these two video categories, four features including camera motion, structure, audio feature and combined feature are adopted and studied along with with four popular classifiers KNN, SVM GMM and C4.5. Extensive experiments over carefully-constructed, representative datasets, evaluate these features and cla...

Stylistic pluralism and the experiences of classically trained teachers of singing in the Republic of Ireland.
(2021)
Fahey, Hannah
Abstract:
Throughout much of the 20th century, the Western classical vocal aesthetic dominated tertiary singing training in the Republic of Ireland. At the turn of the 21st century, and reflecting similar movements internationally, Irish institutions, examining boards and private teaching studios diversified to include musical theatre and popular styles of singing in degree programmes and syllabi. The purpose of this study was to further understand voice teacher perceptions of these shifts in pedagogical culture. This research questioned how classically trained teachers of singing negotiate teaching across styles in popular music genres, and also questioned if implicit, embodied cultural ideas about classical singing defined their educative approaches to popular music vocals. Data were collected through in-depth qualitative interviews with classically trained teachers of singing in the Republic of Ireland. Analysis of interview data revealed a number of themes which are discussed within a the...
