Title: Gamification of Ultrasound Training for Prostate Brachytherapy using Physical Simulator Devices
Authors: Andrea Jane Doyle, Deirdre M King, Jacinta E Browne
Abstract
Prostate cancer is the most diagnosed invasive cancer in men in Ireland at 35.1%. Ultrasound-guided brachytherapy for prostate cancer was introduced in 2007 in Ireland and has since been accepted in a number of treatment centres throughout Ireland, largely due to its benefits for patient recovery, dose-localisation and conformity. The quality of an ultrasound image relies upon the user’s technical and clinical competency. The success of the procedure is based on the correct dose estimation and concise implantation of the radioactive seeds in the prostate.
Although ultrasound forms a critical component of prostate cancer planning and treatment, ultrasound training is not required as part of radiation oncology training programs, nor does any objective competency measure exist to independently assess clinical performance. Physical simulation training and objective competency testing can provide a structured approach to training but only if there are suitably challenging training devices available which replicate the complex anatomy of the male pelvis and prostate. The use of such training strategies allows trainees to track their performance over time, and relative to their peers; thereby, providing a structured and competitive approach to learning.
This study evaluates the specific requirements to develop such a high-quality training programme.

Title: Evaluation of Wind Energy Forecasts: the Overlooked Importanceof Data Cleaning
Authors: Gianni Goretti
Abstract
In electricity markets with high wind energy penetration, wind energy forecasts are increasingly employed for unit commitment and energy trading purposes. The forecast accuracy is evaluated by comparing predicted values against actual observations, which for a wind farm are the measurements of the energy output.
The energy output, however, can be affected by factors that are outside the forecast model’s scope (e.g., events like grid curtailment or turbine outages are generally not predictable). For a consistent evaluation of the forecast, periods affected by such factors should be identified and excluded from the dataset during the data cleaning phase.
The literature offers limited guidance in this regard and studies in this field regularly fail to describe this preliminary yet fundamental phase. As a result, researchers perform the cleaning task based mainly on their knowledge and experience.
The present work shows how the selection of the evaluation dataset changes the analysis results; this, in turn, highlights that if data cleaning criteria are not defined thoroughly, the scientific rigour of the study can be compromised. Finally, this work aims at filling the gap in both literature and industry best practice by defining a data cleaning procedure for the evaluation of wind energy forecasts.

Title: Development of Mechanism based Chemo-Sensitisation strategies to Enhance Anti-Cancer effects of Metal Based Drugs
Authors: Tadhg O’Leary, Steve Gray, Pauraic McCarron, Michael Devereux, Steve Meaney
Abstract
Recently Epigenetic Regulators (HDAC/DNMT inhibitors) have been investigated as potential chemo-sensitising agents of cancer cells towards anti-cancer drugs (e.g. Cisplatin). Novel metal-phenanthroline complexes (manganese, silver and copper based) are currently being developed as novel chemotherapeutics, and are thought to act in a similar manner to Cisplatin. This project aims to investigate chemo-sensitising potential of these regulators in isogenic cisplatin sensitive (CS) and resistant (CR) mesothelioma cell lines towards these novel manganese (i)[Mn2(oda)(phen)4(H2O)2][Mn2(oda)(phen)4(oda)2]4H2O, (ii)([Mn(3,6,9-tdda)(phen)2]3H2O, copper [Cu(3,6,9-tdda)(phen)2]3H2O and Silver [Ag2(phen)3(undecanedioic acid)]3H2O), complexes.
Positive control assays demonstrated modest reactivity of Cisplatin to HDACi valproic acid in CR cells but not CS cells. To date little to no reactivity has been observed in copper or manganese (i) compounds in either cell line, while cell specific reactivity has been observed in manganese (ii) and silver complexes with analogue HDACi Valproic acid and phenylbutyrate. Surprisingly, we noted that treatment with certain epigenetic regulators decreased the efficacy of some compounds in some cellular models. These results will be discussed in relation to both the potential therapeutic opportunities of epigenetic co-sensitisation for metal-based drugs and the possible mechanism underpinning the observed effects.

Title: The Influence of Social Media on the Identity Construction Process in Cross-Domain Identity Transitions – Coming Out as Transgender on Social Media in Ireland
Authors: Jade Kim
Abstract
As gender is a social construct, individuals are expected to enact their gender role according to social conventions. It is a characteristic taken into account when constructing one’s identity. As transgender individuals experience identity asymmetries because their self-view regarding their gender assigned at birth did not coincide with their cultural self, overcoming these asymmetries happen through their Coming-Out process. To counter the risk of abandonment and isolation through rejection linked to this process, learning about oneself and one’s community is crucial. While the access to information has been eased by the internet as it has created a place where anonymity and disembodiment meet, individuals could transcend gender questions and construct their desired identity. However, the rise of social media has made the internet evolve into a “nonymous” environment by re-anchoring the online self and the offline self. The internet of social media is subject to peer evaluation.
Thus, how do transgender individuals manage their Coming-Out process on social media?
This study, through the use of in-depth interviews with transgender individuals in Ireland, aims to give light to how individuals use social media as a tool for identity claims and explorations, and how individuals manage their anchored social sphere online.

Title: A discursive comparison on the models of surveillance in East Germany and Northern Ireland and examining their relevance to the contemporary securitisation of society.
Authors: Cliodhna Pierce
Abstract
With increasing awareness of the rise in the culture of surveillance resulting from the Snowden leaks and the subsequent revelations from Wikileaks, I believe the harms of this practice on the individual and the impact it has on the community has not been fully investigated.
The premise for this research project is to Compare the Community Surveillance state of Northern Ireland and the Governmental Surveillance State of East German Stasi and assess the influence and impact on the society as a whole. By looking at these two extremes through the eyes of both the victims of surveillance and the perpetrators we will get a better understanding of the harms this practice may have.
This research should influence the wider debate on the issue of unlawful surveillance. With the UK seeking to pass Investigatory Powers Bill, this legislation proposes to increase the surveilled powers of the police and intelligence services, and will be aimed at giving police and intelligence agencies the power to monitor online communications. Alongside the increasing terrorist threats many other European countries may follow suit. Looking at two of the most surveilled communities Northern Ireland and East Germany and using these comparisons to assess the harm this has on the wider community. As a result this research will investigate the impact of this breach on our civil liberties going forward.

Title: Exploring the relationship between depicting verbs, constructed actions and non-manual features in Irish Sign Language
Authors: Robert Smith
Abstract
Investigating the hypothesis: “Findings from linguistic analysis and categorisation of non-manual features will improve the performance and understandability of sign language generation systems.”, this work explores the form and function of non-manual features in Irish Sign Language (ISL). With a particular focus on how non-manuals correspond to the use of depicting verbs in the language.
An Initial, high level, statistical analysis identified depicting verbs as the most common grammatical class, in the corpus, to contain non-manual features. Work is currently underway to annotate grammatical class and constructed action in a demographically selected section of the signs of Ireland corpus (Leeson, 2006). The annotation stage is due for completion in January 2018. At which point, the dataset can be analysed based on the co-occurrence of various non-manual features with depicting verbs.
This talk presents a methodological approach and some intermediary findings of ongoing research. Its original contribution comes in the form of a novel linguistic analysis of Irish Sign Language based on contemporary theoretical approaches and a focus on the improvement of computer generated sign language performance quality. This work provides an additional, more practical contribution; in further developing the SOI corpus, such that, the resource is more comprehensively equipped for future research projects.

Title: Depression Diagnosis and Treatment through Speech (DDaTTS)Authors: Caroline De Pasquale, Brian Vaughan
Authors: Caroline De Pasquale, Brian Vaughan
Abstract
The research investigates the phenomenon of prosodic coordination in clinical interviews with depressed patient. In particular, it focuses on the effect of depressive disorder on coordinative behaviour, and the modification of prosodic parameters on the part of the clinician, in response to the parameters of the patient. The dyads are recorded in live clinical settings during clinical interviews, and several prosodic variables are analysed. Findings indicate that there is clear adaptation on the part of the medical doctor, even going so far as to have a reduced vowel-space ratio mirroring a reduced vowel-space ratio in the depressed patients. This could be an indication of sympathetic speaking style, and could be a measure of therapeutic alliance. Accommodation scores can potentially help the diagnosis of depression, and be used to evaluate therapeutic sessions.

Title: Harnessing the power of text mining for the detection of abusive content in social media
Authors: Hao Chen, Sarah Jane Delany, Susan McKeever
Abstract
Social media sites facilitate users in posting their own personal comments online. Most support free format user posting, with close to real-time publishing speeds. However, online posts generated by a public user audience carry the risk of containing inappropriate, potentially abusive content.
The aim of our project is to investigate both traditional and recent machine learning techniques for the automatic detection of abusive content across a range of social media sources include blogs, forums, media-sharing, Q&A and chat. Besides analysing the datasets from public recourses such as Twitter, YouTube, we presented our own labelled dataset. Based on these datasets, we carried out supervised classifiers and explored the various feature representations include bag of words, n-grams and newest approach – word embedding. We also performed feature engineering to extract useful syntactic and semantic feature in order to improve the detection accuracy.
The contributions of our work are proposing an aggregated mechanism for assessing different opinions from different labellers, and using machine learning to classifying abusive comments which would assist the moderators on social media sites to target abusive comments.

Title: In vitro comparative cytotoxicity study of Aminated Polystyrene, Zinc Oxide and Silver nanoparticles on cervical cancer cell line.
Authors: Akash Sharma, Brian Gorey, Alan Casey
Abstract
Nanoparticles use in nano-biotechnology applications have increased significantly with Aminated polystyrene amine (AmPs NP), Zinc oxide (ZnO NP) and Silver (Ag NP) nanoparticles utilized in wide variety of consumer products. This has presented a number of concerns due to their increased exposure risks and associated toxicity on living systems. Changes in the structural and physicochemical properties of nanoparticles can lead to changes in biological activities. This study investigates, compares and contrasts the potential toxicity of AmPs, ZnO and Ag NPs on an in vitro model (HeLa cells) and assesses the associated mechanism for their corresponding cytotoxicity relative to the surface material. It was noted that NPs exposure attributed to the reduction in cell viability and high-level induction of oxidative stress. All three test particles were noted to induce ROS to varying degrees which is irrespective of the attached surface group. Cell cycle analysis indicated a G2/M phase cell arrest, with the corresponding reduction in G0/G1 and S phase cells resulting in caspase-mediated apoptotic cell death. These findings suggest that all three NPs resulted in the decrease in cell viability, increase intracellular ROS production, induce cell cycle arrest at the G2/M phase and finally result in cell death by caspase-mediated apoptosis, which is irrespective of their differences in physiochemical properties and attached surface groups.

Title: Miniaturised solid state sensors containing ionic liquids for environmental analysis
Authors: Emma Brennan, Prof. John Cassidy, Dr Benjamin Schazmann
Abstract
Our group proposes solid state potentiometric sensors for diclofenac quantification in water. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) prescribed globally as an analgesic and antipyretic. Prophylactic use of diclofenac in cattle herds in South Asia has led to the drug’s biomagnification in scavenging bird populations across the region, resulting in significant population declines for these animals. Diclofenac features on the EPA’s recent lists of Contaminants of Emerging Concern, and has been banned for veterinary use in India, Pakistan and Nepal.
These sensors are prepared on planar carbon based electrodes, which are cost effective and facile to prepare, and feature an ion-selective sensing membrane prepared with novel ionic liquids. The sensors exhibit a near Nernstian response to diclofenac, with a high degree of reversibility between analyte activities and minimal response to prominent interferent anions such as chloride. The solid state, “dry” format negates the requirement for an inner reference solution, yielding a compact and flexible electrode. This, coupled with the passive (potentiometric) mode of measurement, infers electrode suitability for field analysis and continuous monitoring applications.

Title: Development of Hybrid Sol-Gel Microfluidic Devices for Medical Diagnostic Applications
Authors: Emma MacHugh, Brendan Duffy, Mohamed Oubaha
Abstract
Over the past decade, the development of point-of-care (POC) devices that can be used by unskilled operators has been investigated in order to reduce costs and diagnostic times.
Microfluidic devices are required in biosensors for the flowing of the analytes liquids (blood, saliva and urine) onto the sensor areas of the POC. To enable a rapid and efficient delivery of these analytes, the surface properties of the microchannels have to exhibit high surface energies.
In this study we propose to investigate the development of high surface energy hybrid sol-gel materials that can be simultaneously photoreactive for microstructuration of high resolution microchannels by standard photolithography processes. In order to achieve this, a series of hybrid sol-gel materials have been developed. These materials were deposited as thin films and the curing temperature of the coatings was investigated. The structure and the surface properties of the materials were characterised by DLS, DSC, FTIR and contact angle. It is shown that both the materials formulations and the curing temperature exhibit a significant effect on the condensation of the silicate network with a direct effect on the contact angle value. A correlation between the structure and the surface properties of the coatings is proposed.
