description: "Light as a Sign of the Existence of God in Liturgy on the basis of a chosen euchology of the Roman Missal". The article analyses chosen euchologies of the Roman Missal. Through a review of certain mass prayers, a picture of light (lux – lumen) emerges that is rich in deep theo- logical content. The light is a magnificent sign of the existence of God in the Liturgy of the Church as the Roman Missal testifies. First of all, we learn who is God as the Light and what is His activity towards the redemption of the human being. Secondly, a truth about the human being emerges from these prayers – who is the one living in the light of the Lord and what is his/her fate?; what is his/her path guided by the light which is a redeeming gift from God? There is also a strong reference to the Creation which is a work of the Light and serves the human being to reach the objective for which he/ she has been created. Those three levels of the engagement of the Light, which eventu- ally became the Body to live among us and give us the gift of the light of life, allow us to talk about the aspects of God’s existence whose sign in the Liturgy is the Light. It is a dogmatic aspect since it concerns the truths about God’s revelation, but also a historic- redemptive soteriological one, as it talks of God’s redemptive intervention, of the victory of light over darkness. But it is never abstract because the Holy Liturgy, where signs of God’s existence can be found in the symbol of light, is said in Church. Thus we are talking about the ecclesiastical aspect of this liturgical sign. Finally also, because of the life objective of the human being, we can talk of the eschatic aspect of that sign, because the aim is to achieve eternal life and light. This richness of theological content emerges from mass euchology. It is possible to find more of such examples, but the aim of this article was not to fully exploit the subject matter but to enhance the reader to deepen and develop his/her spiritual absorption of God’s light in his/her life.

description: A current challenge in atomistic machine learning is that of efficiently predicting the response of the electron density under electric fields. We address this challenge with symmetry-adapted kernel functions that are specifically derived to account for the rotational symmetry of a three-dimensional vector field. We demonstrate the equivariance of the method on a set of rotated water molecules and show its high efficiency with respect to number of training configurations and features for liquid water and naphthalene crystals. We conclude showcasing applications for relaxed configurations of gold nanoparticles, reproducing the scaling law of the electronic polarizability with size, up to systems with more than 2000 atoms. By deriving a natural extension to equivariant learning models of the electron density, our method provides an accurate and inexpensive strategy to predict the electrostatic response of molecules and materials.

description: We have launched a search for large-scale ($\gapprox$1 kpc) minor-axis outflows in edge-on Seyfert galaxies in order to assess their frequency of occurrence and study their properties. Here we present optical continuum and \han2 line images and/or minor-axis long-slit spectra of 22 edge-on Seyfert galaxies. Six of these galaxies show at least one of the following: (i) bi-symmetric H$α$ halos extending along the minor axis, (ii) bright emission-line complexes at distances $\gapprox$4 kpc (in projection) out of the disk, and (iii) double-peaked emission-line profiles from the gas along the minor-axis, suggesting that a wind-blown bubble is present. Our results indicate that $\gapprox$${{1}\over{4}}$ of Seyferts have good evidence for minor-axis galactic outflows. Kinetic luminosities of the galactic outflows in our sample Seyferts are $\sim$10$^{40}$$-$10$^{42}$ erg~s$^{-1}$, assuming all of the observed minor-axis emission is produced by the outflow. These values are, in general, $\sim$0.1 as large as those for well-studied cases of superwinds in starburst galaxies (Heckman, Armus \& Miley 1990). However, far-infrared luminosities of our sample Seyferts are also $\sim$0.1 as large. Both starburst-driven superwinds and wide-angled outflows from the active galactic nucleus are possible explanations for the observed large-scale outflows.

description: Women are underrepresented in Science, Technology, Engineering and Mathematics (STEM). There are many initiatives which have been implemented in efforts to change this imbalance, including in primary, secondary and third-level institutions. Some are supported by governments, for example, by Science Foundation Ireland in Ireland, by professional bodies, such as IEEE, and by companies. Initiatives are targeted at STEM in general, and at subsets of the discipline. In fact, there are many STEM intervention programmes worldwide from which we in software engineering can learn. The logistics around planning and implementing a STEM intervention programme are many. This is compounded when a programme must quickly pivot and change how it is provided due to external factors. While this paper presents our experience on one STEM intervention, the University of Limerick-Lero/Johnson & Johnson WiSTEM2 D (Women in STEM, Manufacturing and Design) programme, it also discusses and describes the challenges and the opportunities that became apparent when it had to completely change how it was deployed and implemented due to the COVID-19 pandemic.

description: Several coronal bright points identified in a quiet region of the Sun from SOHO/EIT Fe XII images are found to have a time evolution from birth to decay which is extremely well correlated with the rise and fall of magnetic flux as determined from photospheric magnetograms made with the SOHO/MDI instrument. Radiative losses of the bright points are found to be much less than conductive losses but the sum of the two is comparable with the available energy of the associated magnetic field. Several small `network flares' occur during the lifetimes of these bright points, emphasizing the strong connection of such events with the magnetic field.

description: NICMOS observations of the complex gravitational lens system B1933+503 reveal infrared counterparts to two of the inverted spectrum radio images. The infrared images have arc-like structures. The corresponding radio images are also detected in a VLBA map made at 1.7 GHz with a resolution of 6 mas. We fail to detect two of the four inverted radio spectrum components with the VLBA even though they are clearly visible in a MERLIN map at the same frequency at a different epoch. The absence of these two components could be due to rapid variability on a time-scale less than the time delay, or to broadening of the images during propagation of the radio waves through the ISM of the lensing galaxy to an extent that they fall below the surface brightness detectability threshold of the VLBA observations. The failure to detect the same two images with NICMOS is probably due to extinction in the ISM of the lensing galaxy.

description: A $(v,k,t)$ {\em covering design}, or {\em covering}, is a family of $k$-subsets, called blocks, chosen from a $v$-set, such that each $t$-subset is contained in at least one of the blocks. The number of blocks is the covering's {\em size}, and the minimum size of such a covering is denoted by $C(v,k,t)$. This paper gives three new methods for constructing good coverings: a greedy algorithm similar to Conway and Sloane's algorithm for lexicographic codes~\cite{lex}, and two methods that synthesize new coverings from preexisting ones. Using these new methods, together with results in the literature, we build tables of upper bounds on $C(v,k,t)$ for $v \leq 32$, $k \leq 16$, and $t \leq 8$.%

description: The data from the Nobeyama Radio Observatory 45 m telescope Galactic Center CO survey have been analyzed to generate a compilation of molecular clouds with intense CO emission in this region. Clouds are identified in an automated manner throughout the main part of the survey data for all CO emission peaks exceeding 10 K ($T_R^*$). Correlations between the size, velocity dispersion, virial mass, and the CO luminosity, for the molecular clouds in the Galactic center were shown. We diagnosed gravitational stabilities of identified clouds assuming that the disk clouds are nearly at the onset of gravitational instability. Most of the clouds and cloud complexes in the Galactic center are gravitationally stable, while some clouds with intense CO emission are gravitationally unstable.

Labos 1point5 : a collective action to reduce the carbon footprint of research at the scale of France
Creators: name: Berné, Olivier
Publisher: name: Zenodo
Year: 2021

description: Researchers have come to realize that research itself produces a carbon footprint. In the context of a global climate emergency, academia has a role in producing knowledge, teaching, and raising broad- based awareness about the issues - but not at the expense of exacerbating the underlying problems.
 In 2019, the Labos 1point5 project was launched in France to engage the academic community in a transformative path toward reducing carbon emissions in research activities. Today, working across disciplines, over 2000 members of the French academic community - including above 600 actively working in six project teams - are using the latest tools and data to evaluate, understand and decrease the carbon footprint of their own research activities. Since 2019, Labos 1point5 has reached several objectives : • Creating and sharing of the GES 1point5 online open-source tool [1] to estimate carbon footprints at the scale of an entire research lab. Currently, about 200 research labs are completing their carbon footprint estimates with GES 1point5, and about 20 are enrolled in an in-situ experiment to target the most efficient emission-reduction actions. GES 1point5 constitutes a unique database to asses the carbon footprint of research at the scale of a country. • Developing and disseminating a nationwide sociological survey to deepen understanding of the structural and practical issues involved in reducing carbon footprints. Over 7000 answers to the survey have been received so far and scientific analysis has started. • Negotiating with major public research institutions to facilitate access to data related to carbon emissions, and create an official structure (Groupement de recherche Labos 1point5) to support research activities on the subject. In this presentation, I present the status of the Labos 1point5 project and its first scientific results, as well as a number of perspectives. [1] Mariette, J., Blanchard, O., Berné, O., & Ari, T. B.

An exact analysis of stable allocation

description: Shapley and Scarf introduced a notion of stable allocation between traders and indivisible goods, when each trader has rank-ordered each of the goods. The purpose of this note is to prove that the distribution of ranks after allocation is the same as the distribution of search distances in uniform hashing, when the rank-orderings are independent and uniformly random. Therefore the average sum of final ranks is just $(n+1)H_n-n$, and the standard deviation is O(n). The proof involves a family of interesting one-to-one correspondences between permutations of a special kind.

description: Saffron is considered a very valuable substance, containing vitamins B, C, A, PP, minerals such as iron, calcium, magnesium, sodium, fluoride, potassium, and essential oils. Many countries produce medicinal preparations and supplements based on saffron in traditional medicine: improving digestive activity, detoxifying the body, removing toxins, relieving pain and spasms, calming the nervous system, increasing skin elasticity, improving skin condition, enhancing the activity of the hematopoietic system, inhibiting the development of pathogenic flora in the body, and strengthening the immune system. Saffron acts as an antispasmodic, anticoagulant, diuretic, and anti-inflammatory agent. It enhances memory and improves digestion. Saffron is used to treat dry bronchitis, asthma, and coughs. Its medicinal infusion is used to heal deep wounds and burns. Its antimutagenic properties and ability to counteract the development of sarcoma tumors are actively being studied. Its pleasant aroma is recommended for treating respiratory tract infections.

description: Chemically peculiar stars present spectral and photometric variability with a single period. In the oblique rotator model, the non homogeneous distribution of elements on the stellar surface is at the origin of the observed variations. As to helium weak stars, it has been suggested that photometric and helium line equivalent width variations are out of phase. To understand the behaviour of helium in CP stars, we have obtained time resolved spectra of the HeI5876 A line for a sample of 16 chemically peculiar stars in the spectral range B3 -- A1 and belonging to different sub-groups. The HeI5876 A line is too weak to be measured in the spectra of the stars HD 24155, HD 41269, and HD 220825. No variation of the equivalent width of the selected He line has been revealed in the stars HD 22920, HD 24587, HD 36589, HD 49606, and HD 209515. The equivalent width variation of the HeI5876 A line is in phase with the photometric variability for the stars HD 43819, HD 171247 and HD 176582. On the contrary it is out of phase for the stars HD 28843, HD 182255 and HD 223640. No clear relation has been found for the stars HD 26571 and HD 177003.

PET-labelled phosphonium cations for mitochondria imaging
Creators: name: McCluskey, Stuart Paul
Publisher: name: Imperial College London
Year: 2017

description: This thesis details the characterisation of lipophilic cation radiotracers for biomedical imaging. The radiotracers discussed are based on triphenylphosphonium cations which can accumulate in the mitochondria and are radiolabelled with either [18F] or [11C]. Implementation of existing radiotracers and development of novel [11C] based di- phosphonium di-cation radiotracers is described in Chapter 3. The chemistry required to produce precursors, reference compounds and radiolabelling is discussed and resulted in implementation of three existing [18F] radiotracers and development of four novel [11C] radiotracers. The later chapters focus on assessment of biological properties of the tracers. This is achieved through studies carried out in vitro, including characterisation in cells and work carried out on an isolated perfused heart model, as well as in vivo studies. In all biological systems radiotracers were assessed under standard conditions and under challenge conditions. The challenge conditions included treatment with a mitochondrial membrane uncoupler, mitochondrial complex inhibitor and a chemotherapy agent. Alteration in radiotracer properties were compared between radiotracers. This work provides a strong foundation for justifying the translation of one of the investigated compounds into man.

Computer-aided segmentation and quantification in contrast-enhanced echocardiography
Creators: name: Li, Yuanwei
Publisher: name: Imperial College London
Year: 2017

description: Myocardial contrast echocardiography (MCE) uses microbubble contrast agents and ultrasound to visualise myocardial vasculature and perfusion in the human body. MCE perfusion analysis can aid in the diagnosis of coronary artery disease (CAD). However, most analyses rely on human visual assessments which are subjective and operator-dependent. There is a strong need to develop automatic MCE quantification methods but this is hindered by 1) the high variabilities in MCE data and 2) the lack of robust and easy-to-use computerised quantification tools. The thesis aims to develop automatic segmentation and quantification methods for fast, accurate and operator-independent MCE perfusion assessment in order to aid the diagnosis of CAD. Firstly, a fully automatic approach is developed for fast and accurate myocardial segmentation in 2D MCE sequence. The method is primarily based on the random forest framework and is additionally constrained by a statistical shape model of the myocardium to improve the final segmentation. When evaluated on human MCE sequences, our proposed approach produces accurate segmentation results, outperforming the other state-of-the-art segmentation approaches. Secondly, a robust and easy-to-use software is developed specifically for MCE perfusion quantification. The software allows for semi-automatic myocardial segmentation, attenuation correction, automatic rejection of poor quality data and automatic perfusion quantification. The developed software demonstrates good CAD diagnostic performance comparable to that of MCE visual assessments and SPECT. Perfusion quantification using the software is also fast, reproducible and less operator-dependent. Finally, two advanced MCE quantification techniques are explored. The first involves developing more sophisticated perfusion models for MCE quantification based on knowledge of physiology and ultrasound physics. The second involves employing a support vector machine for CAD detection based on the perfusion parameters extracted from the various perfusion models. The combination of these two techniques has improved the accuracy of CAD diagnosis.

description: Recent advancements in stellar evolution modeling offer unprecedented accuracy in predicting the evolution and deaths of stars. We present new stellar evolutionary models computed with the updated PARSEC V2.0 code for a comprehensive and homogeneous grid of metallicities and initial masses. Nuclear reaction networks, mass loss prescriptions, and the treatment of elemental mixing have all been updated in PARSEC V2.0. We computed models for thirteen initial metallicities spanning $Z = 10^{-11}$ to $Z = 0.03$, with masses ranging from 2.0 M$_{\odot}$ to 2000 M$_{\odot}$, consisting of a library of over 1,100 ($\sim 2100$ tracks including pure-He models) full stellar evolution tracks. For each track, the evolution is followed from the pre-main-sequence to the most advanced early-asymptotic-giant-branch or the pre-supernova phases, depending on the stellar mass. Here, we describe the properties of the tracks and their chemical and structural evolution. We computed the final fates and the remnant masses and built the mass spectrum for each metallicity, finding that the combined black hole (BH) pair-instability mass gap spans just between 100 and 130 M$_{\odot}$. Moreover, the remnant masses provide models consistent with observed BH masses, such as those from the primaries of GW190521, Cygnus X-1, and $\textit{Gaia}$ BH3 binary systems. We computed and provided the chemical ejecta from stellar winds and explosive final fates, along with the ionizing photon rates. Our results show strong overall consistency with other tracks computed with different codes. A comparison with a large sample of observed massive stars in the Tarantula Nebula of the Large Magellanic Cloud shows that our tracks nicely reproduce the majority of stars that lie on the main sequence. All the models are publicly available and can be retrieved on the PARSEC database.

description: Given $n$ real numbers $0\leq x_1,...,x_n<1$ and a permutation~$σ$ of $\{1,...,n\}$, we can always find $\xbar_1,...,\xbar_n\in\{0,1\}$ so that the partial sums $\xbar_1+... +\xbar_k$ and $\xbar_{σ1}+... +\xbar_{σk}$ differ from the unrounded values $x_1+... + x_k$ and $x_{σ1}+... +x_{σk}$ by at most $n/(n+1)$, for $1\leq k\leq n$. The latter bound is best possible. The proof uses an elementary argument about flows in a certain network, and leads to a simple algorithm that finds an optimum way to round.
Functionalised microbubbles for dual-modality imaging
Creators: name: Harriss, Bethany Ivy
Publisher: name: Imperial College London
Year: 2017

description: Medical imaging is ubiquitous in disease diagnosis and monitoring, with many different methods available. The aim of dual-modal contrast agents is to synergistically combine two of these into one probe in order to enhance the information obtained. Early and accurate detection of diseases is crucial in improving patient prognosis and survival rates. For this reason, this thesis aims to develop cancer-specific contrast agents which combine multiple imaging modalities into one probe. Ultrasound is a commonly used imaging modality as it is cheap, easy to use, portable and provides real-time images. It is frequently used to assess the abdominal organs and monitor foetus development, however cancerous tissues can be difficult to observe under normal conditions. Microbubbles are clinically used ultrasound contrast agents that can improve the visualisation of tumours. These are composed of a gas core stabilised by a surface coating such as a phospholipid and are the ideal platform for further functionalisation. During this project, phospholipids have been functionalised with the cancer-targeting peptide RGD and fully characterised using NMR, MALDI-TOF and UPC2-ES+. These were then formed into microbubbles and their selective binding proved through in vivo work. Phospholipids were then functionalised with moieties to allow for coordination to 68Ga, a PET isotope. Initial experiments involved the radiolabelling of a small molecule followed by functionalisation of the microbubble surface. Unfortunately this did not yield radiolabelled microbubbles, therefore latter experiments focussed on direct radiolabelling of a phospholipid and subsequent formation into microbubbles. This route resulted in radiolabelled microbubbles, with further development underway to improve this reaction. Phospholipid functionalisation with pH sensitive and pH insensitive fluorophores was also performed, their fluorescence properties assessed and incorporation of modified phospholipids into microbubbles proved by microscope visualisation under laser irradiation. These were then formed into nanodroplets, with the goal of using the optical absorbers to induce selective vaporisation into microbubbles. Further work will assess the vaporisation properties of these nanodroplets. Finally, small molecule fluorescence-MRI and fluorescence-PET probes were developed for use with microbubbles to mediate delivery across the blood-brain-barrier. Preliminary results indicate successful, selective delivery using this technique, with further testing underway.

description: A model of environmental regulation with interdependent production and pollution abatement costs and heterogeneous firms is developed. Firms have private information about costs which have a quadratic form. A budget-balancing problem is shown to—exist --- even with Bayes-Nash strategies. The full information optimum cannot be attained unless gains from trade in the product market net of external damages exceed the information rents earned by firms.

description: Large Language Models (LLMs) have made significant strides in mathematical reasoning, underscoring the need for a comprehensive and fair evaluation of their capabilities. However, existing benchmarks often fall short, either lacking extensive coverage of undergraduate-level mathematical problems or probably suffering from test-set contamination. To address these issues, we introduce UGMathBench, a diverse and dynamic benchmark specifically designed for evaluating undergraduate-level mathematical reasoning with LLMs. UGMathBench comprises 5,062 problems across 16 subjects and 111 topics, featuring 10 distinct answer types. Each problem includes three randomized versions, with additional versions planned for release as leading open-source LLMs become saturated in UGMathBench. Furthermore, we propose two key metrics: effective accuracy (EAcc), which measures the percentage of correctly solved problems across all three versions, and reasoning gap ($Δ$), which assesses reasoning robustness by calculating the difference between the average accuracy across all versions and EAcc. Our extensive evaluation of 23 leading LLMs reveals that the highest EAcc achieved is 56.3\% by OpenAI-o1-mini, with large $Δ$ values observed across different models. This highlights the need for future research aimed at developing "large reasoning models" with high EAcc and $Δ= 0$. We anticipate that the release of UGMathBench, along with its detailed evaluation codes, will serve as a valuable resource to advance the development of LLMs in solving mathematical problems.

description: The release of a gregarious parasitoid as a biological control agent in a relatively simple grassland ecosystem provides a rare opportunity to observe the outcomes of parasitoid density dependent oviposition behaviour in the field. A retrospective analysis was undertaken of monthly host population data collected over the three years following the release of a parthenogenetic and facultative gregarious Irish genotype of the endoparasitoid Microctonus aethiopoides Loan in New Zealand in 2006 for control of Sitona obsoletus Gmelin in pasture. Brood size ranged from one to seven parasitoids/host, with a mean of 1.63 ± 0.04, and was not influenced by locality, host gender or host weight. It was positively correlated with percent parasitism and to a lesser degree with host abundance. Scramble competition varied with brood size, but not host weight, and resulted in 33% larval mortality at prepupae emergence. Size and fecundity of adults from broods increased with increasing host weight up to a threshold of 4 mg host resources/parasitoid larva. Above this level, size and fecundity stabilised. A simple fitness model suggested that optimum brood size varies with host availability from 1, when the number of available hosts/ adult parasitoid is 65 or greater, to 3 when hosts/parasitoid is 29 or fewer. The ability to vary brood size with host abundance to maximise reproductive efficacy contributes to the observed efficacy of Irish M. aethiopoides as a biological control agent in New Zealand.

Modulation of sensorimotor and perceptual components of balance in disease
Creators: name: Lee, Pei-Yun
Publisher: name: Imperial College London
Year: 2013

description: Balance disorders are common in many neurological diseases. Well-controlled balance requires all balance systems, including visual, vestibular, and somatosensory system, providing specific information about position and motion of the body and the motor system executing appropriate strategies. The aim of the thesis is to apply modulation of visual, vestibular, and somatosensory systems in order to develop new treatments for balance disorders. In this thesis, two types of balance disorders were investigated separately: i) Parkinson’s disease (PD), caused by central nervous system neurodegeneration, and ii) vestibular disorders, caused by peripheral vestibular dysfunction. Both patients groups experience difficulties in postural control. In order to determine an efficient therapeutic method to improve their balance function, the efficacy of different assistive techniques, treatments, and physiotherapy on performance was examined in the two patients groups. First, characteristics of protective stepping response in healthy young and elderly adults were examined. Participants were tested on a moving platform prompting a protective step to characterise their forward and backward stepping responses. Second, characteristics of protective stepping response in PD patients were described. Use of vibrotactile feedback on protective stepping response was also tested to investigate its effect on enhancing the stepping response in PD patients via the somatosensory system. Third, non-invasive brain stimulation, transcranial direct current stimulation (tDCS), incorporated with physiotherapy was applied on PD patients to investigate its effect on protective stepping response via changing corticomotor excitability. The last part of the thesis, intensive visual motion stimulation incorporated within a customised exercise programme was provided to patients with peripheral vestibular disorders and visual vertigo, whereby patients experience symptom provocation or exacerbation when exposed to busy visual motion environments (i.e. crowds) to investigate whether this intensive programme could enhance improvement of subjective visual vertigo symptoms and objective perceptual and postural measures of visual dependency. In general, the efficacy of different assistive techniques and treatment schemes on balance control in patients with PD or vestibular disorders was studied. The outcome of different treatment techniques will be presented in the thesis.

description: Composites of flexible and rigid polymers are ubiquitous in biology and industry alike, yet the physical principles determining their mechanical properties are far from understood. Here, we couple force spectroscopy with large-scale Brownian Dynamics simulations to elucidate the unique viscoelastic properties of custom-engineered blends of entangled flexible DNA molecules and semiflexible actin filaments. We show that composites exhibit enhanced stress-stiffening and prolonged mechano-memory compared to systems of actin or DNA alone, and that these nonlinear features display a surprising non-monotonic dependence on the fraction of actin in the composite. Simulations reveal that these counterintuitive results arise from synergistic microscale interactions between the two biopolymers. Namely, DNA entropically drives actin filaments to form bundles that stiffen the network but reduce the entanglement density, while a percolating actin network is required to reinforce the DNA network against yielding and flow. The competition between bundling and percolation triggers an unexpected stress response that leads equal mass actin-DNA composites to exhibit the most pronounced stress-stiffening and the most long-lived entanglements.
A volume-preserving counterexample to the Seifert conjecture

description: We prove that every 3-manifold possesses a $C^1$, volume-preserving flow with no fixed points and no closed trajectories. The main construction is a volume-preserving version of the Schweitzer plug. We also prove that every 3-manifold possesses a volume-preserving, $C^\infty$ flow with discrete closed trajectories and no fixed points (as well as a PL flow with the same geometry), which is needed for the first result. The proof uses a Dehn-twisted Wilson-type plug which also preserves volume.
The Isolated Elliptical NGC 1132: Evidence For a Merged Group of Galaxies?

description: Numerical simulations predict that some poor groups of galaxies have merged by the present epoch into giant ellipticals (cf. Barnes 1989). To identify the possible remnants of such mergers, we have compiled a sample of nearby, isolated ellipticals (Colbert, Mulchaey, & Zabludoff 1998). ASCA observations of the first galaxy studied, NGC 1132 reveal an X-ray halo that extends out to at least 250 kpc. The temperature, metallicity and luminosity of NGC 1132's X-ray halo are comparable to those of poor group halos. The total mass inferred from the X-ray emission is also like that of an X-ray detected group. Optical imaging uncovers a dwarf galaxy population clustered about NGC 1132 that is consistent in number density and in projected radial distribution with that of an X-ray group. The similarities of NGC 1132 to poor groups in both the X-ray band and at the faint end of the galaxy luminosity function, combined with the deficit of luminous galaxies in the NGC 1132 field, are compatible with the merged group picture. Another possibility is that the NGC 1132 system is a `failed' group (i.e., a local overdensity in which other bright galaxies never formed).

description: Accessible epidemiological data are of great value for emergency preparedness and response, understanding disease progression through a population, and building statistical and mechanistic disease models that enable forecasting. The status quo, however, renders acquiring and using such data difficult in practice. In many cases, a primary way of obtaining epidemiological data is through the internet, but the methods by which the data are presented to the public often differ drastically among institutions. As a result, there is a strong need for better data sharing practices. This paper identifies, in detail and with examples, the three key challenges one encounters when attempting to acquire and use epidemiological data: 1) interfaces, 2) data formatting, and 3) reporting. These challenges are used to provide suggestions and guidance for improvement as these systems evolve in the future. If these suggested data and interface recommendations were adhered to, epidemiological and public health analysis, modeling, and informatics work would be significantly streamlined, which can in turn yield better public health decision-making capabilities.

Probabilistic species-driven gene mention normalisation
Creators: name: Harmston, Nathan
Publisher: name: Imperial College London
Year: 2013

description: The scientific literature is an important for source of knowledge about biological sys- tems and their constituent components. But the increase in the rate of new publications means that manual curation of the literature has become intractable. This has motivated the development and application of text mining methods to automatically extract the in- formation present in the scientific literature. Extracting information automatically from text is, however, an inherently noisy process and this uncertainty provides the rationale for the development of probabilistic methods for text mining. In this thesis, we concern ourselves with the task of identifying gene mentions in text and normalising these to unique Entrez gene identifiers, referred to as species-driven gene mention normalisation. We propose novel heuristics which improve the performance of species mention normalisation and reduce the number of ambiguous mentions found in the MEDLINE database. This directly impacts the performance down- stream components and we provide a novel probabilistic method for assigning a species to individual gene mentions. In order to avoid uncertainties and noise being propagated in text-mining approaches we develop a Bayesian network description of a text mining pipeline, which allows us to quantify uncertainties reliably and in an easily interpretable manner. Our results show the importance of incorporating as much information as possible into the text mining pipeline and the importance of viewing text mining as a noisy system.
