description: We present high-contrast observations of the circumstellar environment of the Herbig Ae/Be star HD100546. The final 3.8 micron image reveals an emission source at a projected separation of 0.48"+-0.04" (corresponding to ~47+-4 AU at a position angle of 8.9+-0.9 degree. The emission appears slightly extended with a point source component with an apparent magnitude of 13.2+-0.4 mag. The position of the source coincides with a local deficit in polarization fraction in near-infrared polarimetric imaging data, which probes the surface of the well-studied circumstellar disk of HD100546. This suggests a possible physical link between the emission source and the disk. Assuming a disk inclination of ~47 degree the de-projected separation of the object is ~68 AU. Assessing the likelihood of various scenarios we favor an interpretation of the available high-contrast data with a planet in the process of forming. Follow-up observations in the coming years can easily distinguish between the different possible scenarios empirically. If confirmed, HD100546 "b" would be a unique laboratory to study the formation process of a new planetary system, with one giant planet currently forming in the disk and a second planet possibly orbiting in the disk gap at smaller separations.

description: We analyze the broadband photometric light curves of Seyfert 1 galaxies from the Sergeev et al. (2005) sample and find that a) perturbations propagating across the continuum emitting region are a general phenomenon securely detected in most cases, b) it is possible to obtain reliable time-delays between continuum emission in different wavebands, which are not biased by the contribution of broad emission lines to the signal, and that c) such lags are consistent with the predictions of standard irradiated accretion disk models, given the optical luminosity of the sources. These findings provide new and independent support for standard accretion disks being responsible for the bulk of the (rest) optical emission in low-luminosity active galactic nuclei (AGN). We interpret our lag measurements in individual objects within the framework of this model and estimate the typical mass accretion rate to be

Mapping beach plastics using drone-based (UAV) imaging systems, in conjunction with East Lothian Council.
Creators: name: Papachristos, Anna

Year: 2023

description: Beached plastic and litter are the most common components of marine waste, with wet wipes comprising of increasing concern. In automating the process of detection, unmanned aerial vehicles (UAVs) prove an efficient method for mapping beached litter. UAVs paired with multispectral sensors are an accessible option for councils for the semi-automation of mapping beached plastic litter. The method of classifying plastic on a coastal section of Tyninghame beach was evaluated through simple and complex classes. Detection methods of pixel- and object-based classification methods, using the supervised classification method of support vector machine (SVM) were compared across the UAV surveys. It was found that segmentation and training samples do not transfer across spatial resolutions, as their performance is variable. Additionally, object-based image analysis (OBIA) proves highly effective at 89-98 % overall accuracy, compared to the pixel-based image analysis (PBIA) across the UAV surveys conducted. This research demonstrates OBIA and SVM as an effective combination for mapping and detecting beach plastics for the beach environment in East Lothian, Scotland for the given plastic litter samples tested. Future suggestions include the further discrimination of the litter classes to improve the accuracy of detecting specific plastic litter categories, through multispectral UAV surveys.

description: The strong version of the Vafa-Witten theorem is shown may not to hold because the zero condensate from a direct computation of the order parameter is found to be a result on the symmetric vacuum. The validity of the Vafa-Witten theorem relies then on its weak version, that the Goldstone boson is absent in vector-like gauge theories with vanishing θ-angle. The existence of a charged ρ-meson condensate, which violates electromagnetic gauge symmetry, is consistent with this weak version of the Vafa-Witten theorem when applied to strong magnetic fields in QCD.

Exploring the accessibility of high-quality General Practices (GPs) in ageing communities in Scotland
Creators: name: Wang, Shiqi
Publisher: name: The University of Edinburgh
Year: 2023
Subjects: GP, ageing communities, Improved 3SFCA, Visualization

description: General Practices (GPs) provide primary healthcare services and are the first stop for getting treatment and advice. Worryingly, Scotland's GP workforce is in short supply and decreasing yearly. Numerous studies have focused on the geospatial distribution of general practitioners (GPs) in the UK, including specific attention to the Scottish context. Understanding the spatial distribution of GP in Scotland is paramount as it offers valuable insights into healthcare accessibility and resource allocation within the region. In Scotland, the ageing process has been ongoing, and the population of pensionable age is predicted to be 22.9% by 2043, and population ageing is likely to increase the prevalence of age-related diseases in Scotland. This study aimed to investigate GP spatial accessibility and service quality in Scotland's ageing communities. The origin-destination pairs between 6976 data zones and 907 GPs were obtained using network analysis on ArcGIS. An improved 3SFCA algorithm was applied to calculate the spatial accessibility of all GP in Scotland. And refer to the Health and Care Experience Survey 2022 to count the service quality of GP. Finally, it was found that many data zones could not access GP within 10 minutes in walking and cycling modes. There were significant differences in GP accessibility and quality between data zones of different ages in different travel modes. The communities with the lowest levels of ageing differed from the communities with other groups of ageing in terms of GP accessibility as well as quality across all modes of travel. With the improved 3SFCA methodology, a researcher or policymaker can find out the accessibility and quality of facilities within 10 minutes and help assess the construction of 10-minute neighbourhoods.

description: Specification of the germ layers by Nodal signaling has long been regarded as an archetype of how graded morphogens induce different cell fates. However, this deterministic model cannot explain why only a subset of cells at the early zebrafish embryo margin adopt the endodermal fate, whereas their immediate neighbours, experiencing a similar signaling environment, become mesoderm. Combining pharmacology, quantitative imaging and single cell transcriptomics, we demonstrate that sustained Nodal signaling establishes a bipotential progenitor state from which cells can switch to an endodermal fate or differentiate into mesoderm. Switching is a random event, the likelihood of which is modulated by Fgf signaling. This inherently imprecise mechanism nevertheless leads to robust endoderm formation because of buffering at later stages. Thus, in contrast to previous deterministic models of morphogen action, Nodal signaling establishes a temporal window when cells are competent to undergo a stochastic cell fate switch, rather than determining fate itself.

description: Digital Retinal Fundus Images helps to detect various ophthalmic diseases by detecting morphological changes in optical cup, optical disc and macula. Present work proposes a method for the authentication of medical images based on Discrete Wavelet Transformation (DWT) and Spread Spectrum. Proper selection of the Non Region of Interest (NROI) for watermarking is crucial, as the area under concern has to be the least required portion conveying any medical information. Proposed method discusses both the selection of least impact area and the blind watermarking technique. Watermark is embedded within the High-High (HH) sub band. During embedding, watermarked image is dispersed within the band using a pseudo random sequence and a Session key. Watermarked image is extracted using the session key and the size of the image. In this approach the generated watermarked image having an acceptable level of imperceptibility and distortion is compared to the Original retinal image based on Peak Signal to Noise Ratio (PSNR) and correlation value.

description: Context. HD 172555 is a young A7 star belonging to the Beta Pictoris Moving Group that harbours a debris disc. The Spitzer IRS spectrum of the source showed mid-IR features such as silicates and glassy silica species, indicating the presence of a warm dust component with small grains, which places HD 172555 among the small group of debris discs with such properties. The IRS spectrum also shows a possible emission of SiO gas. Aims. We aim to study the dust distribution in the circumstellar disc of HD 172555 and to asses the presence of gas in the debris disc. Methods. As part of the GASPS Open Time Key Programme, we obtained Herschel-PACS photometric and spectroscopic observations of the source. We analysed PACS observations of HD 172555 and modelled the Spectral Energy Distribution (SED) with a modified blackbody and the gas emission with a two-level population model with no collisional de-excitation. Results. We report for the first time the detection of OI atomic gas emission at 63.18 microns in the HD 172555 circumstellar disc. We detect excesses due to circumstellar dust toward HD 172555 in the three photometric bands of PACS (70, 100, and 160 microns). We derive a large dust particle mass of 4.8e-4 Earth masses and an atomic oxygen mass of 2.5e-2*R^2 Earth masses, where R in AU is the separation between the star and the inner disc. Thus, most of the detected mass of the disc is in the gaseous phase.

description: This work presents a 3D interactive gaming paradigm called Cyberball3D+ for the secluded space of an fMRI scanner.  The Cyberball3D+ game is a virtual ball-toss game where participant is either excluded or not from ball tossing played by three virtual players and the subject in the scanner. The game proposed was designed to render an interactive Virtual Environment (VE) on an fMRI display, enabling the conduct of formal neuroscientific experiments and investigating the effects of social exclusion, empathy and different level of anthropomorphism on human brain activity. Although this work focused on the technical implementation of the system, for the first time, we propose a validated neuroscientific fidelity metric of character believability and emotional engagement.
 	The system was developed in close collaboration between the Technical University of Crete where the technical implementation took place and the Brighton and Sussex Medical School where the initial fMRI experiments were conducted using the system proposed.
 	The results demonstrated that participating in a high anthropomorphism environment rather than a low anthropomorphism environment activated both frontal cortex and superior temporal gyrus.  This suggests that compared to more human like avatars, playing the non-anthropomorphic avatars is less subjectively rewarding and potentially anxiogenic. In addition, the results indicated that when studying complex emotional responses, a high level of anthropomorphism of synthetic characters engages neuroscientific patterns of brain activation as in real-world circumstances.
 	A broader aim of this work was to assess whether such powerful social-psychological studies could be usefully carried out within VEs advancing cognitive neuroscience and computer graphics research.

Detecting adversarial examples of text

description: Although deep neural networks have achieved state-of-the-art performance in various tasks, a lot of their decisions are non-interpretable because high dimensional feature vectors cause deep neural net functions to be extremely difficult to visualize, widely used gradient descent is an approximate solution, not an analytical solution, etc. Therefore, there are multiple counter-intuitive and intriguing phenomena in deep classifiers, such as adversarial examples. In natural language and image classification tasks, research on adversarial examples divides into two major categories: generating adversarial examples to attack neural networks and defence against adversaries to protect neural networks. Approaches to adversarial attacks for text classification tasks have boomed in the last three years using character-level, word-level, phrase-level, and sentence-level perturbations. However, as far as we know, textual adversarial defence, especially detecting textual adversarial instances from their normal and noise counterparts, does not have an effective method so far. In this thesis, we apply ensemble learning and sentence representations from different transformer models based on the comprehension of the graph of deep neural nets and the reason for adversarial examples to fill this gap. Our technique obtains state-of-the-art results on character-level and word-level attacks on both IMDB and MultiNLI datasets. For future research, we will publish our code.

description: Let claw be the graph $K_{1,3}$. A graph $G$ on $n\geq 3$ vertices is called \emph{o}-heavy if each induced claw of $G$ has a pair of end-vertices with degree sum at least $n$, and 1-heavy if at least one end-vertex of each induced claw of $G$ has degree at least $n/2$. In this note, we show that every 2-connected $o$-heavy or 3-connected 1-heavy graph is Hamiltonian if we restrict Fan-type degree condition or neighborhood intersection condition to certain pairs of vertices in some small induced subgraphs of the graph. Our results improve or extend previous results of Broersma et al., Chen et al., Fan, Goodman & Hedetniemi, Gould & Jacobson, and Shi on the existence of Hamilton cycles in graphs.

 The value of historical resources in Language Documentation and Description: Case Studies from the Enggano Project Charlotte Hemmings
 University of Oxford Abstract: This seminar discusses the value and limitations of historical resources in the context of Language Documentation and Description using case studies from the Enggano Project, an ongoing project to document the Enggano language, spoken on Enggano Island, off the south coast of Sumatra, Indonesia. Perhaps unusually for an endangered, minority language, Enggano has a rich history of documentation, with wordlists and texts going back to the 19th century (e.g. Helfrich 1916) as well as a systematic documentation conducted in the 1930s by Hans Kähler that comprises a grammar sketch (Kähler 1940), a text collection (Kähler 1955, 1957, 1958, 1960a, b, 1961, 1962, 1964, 1975) and a dictionary (Kähler 1987). In this seminar, I present examples of how these historical materials have helped in the description of contemporary Enggano morphosyntax, as well as facilitating analysis of both language-internal and contact induced change. Consequently, despite the limitations of historical materials, I will argue that they can be of great value to language documentation projects, and in this way contribute to linguistic theory and typology as well.

description: We compare the structural properties of the street networks of ten different European cities using their primal representation. We investigate the properties of the geometry of the networks and a set of centrality measures highlighting differences and similarities among cases. In particular, we found that cities share structural similarities due to their quasi planarity but that there are also several distinctive geometrical proprieties. A Principal Component Analysis is also performed on the distributions of centralities and their respective moments, which is used to find distinctive characteristics by which we can classify cities into families. We believe that, beyond the improvement of the empirical knowledge on streets network proprieties, our findings can open new perspectives in the scientific relation between city planning and complex networks, stimulating the debate on the effectiveness of the set of knowledge that statistical physics can contribute for city planning and urban morphology studies.

description: Classic approaches to game AI require either a high quality of domain knowledge, or
a long time to generate effective AI behavior. Monte Carlo Tree Search (MCTS) is a
search method that combines the precision of tree search with the generality of
random sampling. The family of MCTS algorithms has achieved promising results
with perfect-information games such as Go. In our work, we apply Monte-Carlo Tree
Search to the non-deterministic game "Settlers of Catan", a multi-player board-turnedweb-
based game that necessitates strategic planning and negotiation skills. We
implemented an agent which takes into consideration all the aspects of the game for
the first time, using no domain knowledge.
In our work, we are experimenting using a reinforcement learning method Value of
Perfect Information (VPI) and two bandit methods, namely, the Upper Coefficient
Bound and Bayesian Upper Coefficient Bound methods. Such methods attempt to
strike a balance between exploitation and exploration when creating of the search
tree.
For first time, we implemented an agent that takes into consideration the complete
rules-set of the game and makes it possible to negotiate trading between all players.
Furthermore, we included in our agent an alternative initial placement found in the
literature, which is based on the analysis of human behavior in Settlers of Catan
games.
In our experiments we compare the performance of our methods against each other
and against appropriate benchmarks (e.g., JSettlers agents), and examine the effect
that the number of simulations and the simulation depth has on the algorithms’
performance. Our results suggests that VPI scores significantly better than bandit
based methods, even if these employ a much higher number of simulations. In
addition to this, the simulation depth of the algorithm needs to be calculated so the
method will neither get lost in deep simulations of improbable scenarios neither end
up shortly without given a proper estimation of the upcoming moves. Finally, our
results indicate that our agent performance is improved when the alternative, human
behavior-based, initial placement method.

description: We consider excitation of highly charged hydrogen-like ions by the impact of equivelocity electrons and protons. The kinetic energy of the protons is more than three orders of magnitude larger than that of the equivelocity electrons. It is shown, however, that despite this fact, the electrons can be much more effective in inducing excitation at collision velocities (slightly) above the threshold for electron impact excitation. The basic reason for this is the strong distortion of the motion of the electron by the attractive field of the nucleus of the highly charged ion.

description: Games have always been one of the main forms of entertainment for people. They combine fun, spiritual growth and skill development. For these reasons, games constitute one of the most important areas of research and application of Artificial Intelligence and Machine Learning. This thesis focuses on the board game “Turning Points”. This is a challenging two-player 4 Χ 4 square board game, in which each move corresponds to the placement of a directed arrow to an empty position, possibly causing some rotations of the existing arrows. The goal of the thesis is the design of an agent for the game Turning
Points, who will learn to play and improve against various opponents. The implementation of the agent combines the Minimax with alpha-beta Pruning search technique, an evaluation function and the reinforcement learning algorithm TD-Learning. The combination of these elements results in the extraction of several competitive players, as evidenced by the experimental evaluation procedure. These players faced human players competitively
and efficiently. Interestingly, they also remain competitive in larger boards compared to the basic one in which they have been trained. Finally, a graphical user interface was implemented to enable game playing with users.

description: The objective of this research is to design and implement a fully automated indoor greenhouse. This greenhouse will monitor and adjust the levels of humidity, lighting and temperature in order to maximize plants’ growth. A special feature of the designed greenhouse is its ability to connect wirelessly and to create a network of multiple greenhouses. Thereby, each individual greenhouse may contain plants of the same family, growing under different conditions. Users are also able to interact with each greenhouse and modify its settings through the internet. The next versions will allow users to monitor their plants via their smart phones.

description: The measurement of customer satisfaction is an important part of marketing research allowing the company to get in touch with the buyer and remodel its services in order to improve his experience. In this thesis we attempt to execute a comparative satisfaction analysis concerning the passengers of four major low cost airline companies, AirAsia, EasyJet, RyanAir and Southwest. The research is based on data extracted from the independent customer review site of Skytrax. The collected data are refined and processed using the MUlticriteria Satisfaction Analysis (MUSA) method. Furthermore, using an enhanced type of the analysis method (MUSA+) we compare the results of each company through different ways in order to conduct more enlightening conclusions about each company’s strong points and weaknesses according to the opinion of their passengers and evaluate their positioning against competition.

description: We calculate correlation functions of the R-current or the stress-energy tensor T_{μν} with two non-protected operators dual to generic massive string states with rotation in S^5, in the context of the AdS/CFT correspondence. Field theory Ward identities make predictions about the all-loop behaviour of these correlators. In particular, they restrict the fusion coefficient to be proportional to the R-charge of the operators or to their dimension, respectively, with certain coefficients of proportionality. We reproduce these predictions, at strong coupling, using string theory. Furthermore, we point out that the recently observed strong coupling factorisation of 4-point correlators is consistent with conformal symmetry and puts constraints on the strong coupling expressions of 4-point correlators involving R-currents or the stress-energy tensor.

description: This paper proposed a DWT based Steganographic technique. Cover image is decomposed into four sub bands using DWT. Two secret images are embedded within the HL and HH sub bands respectively. During embedding secret images are dispersed within each band using a pseudo random sequence and a Session key. Secret images are extracted using the session key and the size of the images. In this approach the stego image generated is of acceptable level of imperceptibility and distortion compared to the cover image and the overall security is high.

description: Osseointegrated titanium implants to the cranial skeleton for retention of facial prostheses have proven to be a reliable replacement for adhesive systems. However, improper placement of the implants can jeopardize prosthetic outcomes, and long-term success of an implant-retained prosthesis. Three-dimensional (3D) computer imaging, virtual planning, and 3D printing have become accepted components of the preoperative planning and design phase of treatment. Computer-aided design and computer-assisted manufacture that employ cone-beam computed tomography data offer benefits to patient treatment by contributing to greater predictability and improved treatment efficiencies with more reliable outcomes in surgical and prosthetic reconstruction. 3D printing enables transfer of the virtual surgical plan to the operating room by fabrication of surgical guides. Previous studies have shown that accuracy improves considerably with guided implantation when compared to conventional template or freehand implant placement. This clinical case report demonstrates the use of a 3D technological pathway for preoperative virtual planning through prosthesis fabrication, utilizing 3D printing, for a patient with an acquired orbital defect that was restored with an implant-retained silicone orbital prosthesis.

description: In the field of spintronics the "conductivity mismatch" problem remains an important issue. Here the difference between the resistance of ferromagnetic electrodes and a (high resistive) transport channel causes injected spins to be backscattered into the leads and to lose their spin information. We study the effect of the resulting contact induced spin relaxation on spin transport, in particular on non-local Hanle precession measurements. As the Hanle line shape is modified by the contact induced effects, the fits to Hanle curves can result in incorrectly determined spin transport properties of the transport channel. We quantify this effect that mimics a decrease of the spin relaxation time of the channel reaching more than 4 orders of magnitude and a minor increase of the diffusion coefficient by less than a factor of 2. Then we compare the results to spin transport measurements on graphene from the literature. We further point out guidelines for a Hanle precession fitting procedure that allows to reliably extract spin transport properties from measurements.

description: The temperature and length scale dependence of solvation properties of spherical hard solvophobic solutes is investigated in the Jagla liquid, a simple liquid that consists of particles interacting via a spherically symmetric potential combining a hard core repulsion and a longer ranged soft core interaction, yet exhibits water-like anomalies. The results are compared with equivalent calculations for a model of a typical atomic liquid, the Lennard-Jones (LJ) potential, and with predictions for hydrophobic solvation in water using the cavity equation of state and the extended simple point charge (SPC/E) model. We find that the Jagla liquid captures the qualitative thermodynamic behavior of hydrophobic hydration as a function of temperature for both small and large length scale solutes. In particular, for both the Jagla liquid and water, we observe temperature-dependent enthalpy and entropy of solvation for all solute sizes as well as a negative solvation entropy for sufficiently small solutes at low temperature. The results suggest that, compared to a simple liquid, it is the presence of a second thermally accessible repulsive energy scale, acting to increasingly favor larger separations for decreasing temperature, that is the essential characteristic of a liquid that favors low-density, open structures and models hydrophobic hydration, and that it is the presence of this second energy scale that leads to the similarity in the behavior of water and the Jagla liquid. The implications of the temperature and length scale dependence of solvation free energies in water-like liquids are explored with a simple model for the aggregation of solvophobic solutes. We show how aggregate stability depends upon the size of the aggregate and the size of its constituent solutes, and we relate this dependence to cold-induced destabilization phenomena such as the cold-induced denaturation of proteins.
