description: Using a careful choice of infrared (IR) subtraction scheme, we demonstrate the cancellation of all terms with transcendental weights 0,1,2 from the finite part of the full-color two-loop four-gluon $\mathcal{N}=2$ supersymmetric QCD amplitude, with $N_f$ massless supersymmetric quarks. This generalizes the previously observed cancellation of weight-2 terms in the superconformal theory, where $N_f=2N_c$ for gauge group SU$(N_c)$. The subtraction scheme follows naturally both from general IR factorization principles and from an integrand-level analysis of divergences in this amplitude. The divergences are written in terms of scalar triangle integrals whose expressions are known to all orders in the dimensional regulator $ε=(4-D)/2$. We also present integrated expressions for the full-color two-loop four-point amplitudes with both matter and vectors on external legs in which lower-weight terms also cancel using an appropriate IR scheme. This provides us with values for the two-loop cusp, gluonic, and quark anomalous dimensions in $\mathcal{N}=2$ supersymmetric QCD, which are cross-checked between the three different amplitudes.

description: We have developed a formalism suitable for calculation of the output spectrum of a detector continuously measuring quantum coherent oscillations in a solid-state qubit, starting from microscopic Bloch equations. The results coincide with that obtained using Bayesian and master equation approaches. The previous results are generalized to the cases of arbitrary detector response and finite detector temperature.

Navigating Toward Success: Black and Minority Ethnic Students in Postgraduate Science, Technology, Engineering and Mathematics Courses in England
Creators: name: Jackson-Cole, Dominik
Publisher: name: University of East London
Year: 2019

description: This thesis aims to address a paucity in the literature of the experiences of ‘home’ Black and Minority Ethnic (BME) students in postgraduate (PG) education in England, with a particular focus on Science, Technology, Engineering and Mathematics (STEM). This is done by (1) identifying institutional barriers to access to and progression through PG study, including the role of Widening Participation (WP) policy and (2) the factors facilitating educational success of BME students. This thesis uses a multi-faceted framework of intersectionality (Crenshaw, 1991), Critical Race Theory (CRT) (Gillborn, 2008), Bourdieusian thinking tools (Bourdieu 1997) and Yosso’s (2005) community cultural wealth (CCW) capitals (aspirational, linguistic, social, navigational, familial and resistant). It argues for the addition of what is theorised as perspective capital to the CCW framework, which can be seen as a resource that allows people of colour to make contributions to the field, stemming from a perspective which is not readily available to people from dominant groups. The data includes semi-structured initial (n=15) and follow up interviews (n=10) with BME students in PG STEM courses, semi-structured interviews with university staff (n=18), student survey (n=246) and various policy and marketing documents. The data suggests that the lack of intersectional thinking in the conceptualisation of WP policy has had negative impacts on BME students. Furthermore, BME students in this research experienced othering. This stemmed from academics’ discourses marking racial difference and from how the organisational structures of the PG field relegated these students to a category of needing support. This had negative impacts on their progression and mental wellbeing. However, students in this study had a range of capitals at their disposal, which allowed them to navigate the PG field. This thesis makes a significant contribution to knowledge by developing Yosso’s work to include a new notion of perspective capital and fine-tuning the conceptualisations of linguistic and social capitals within the CCW framework.

description: This study evaluates the impact of Heifer International’s livestock donation program in the Copperbelt Province in Zambia. Using a panel data of 300 households and 4 survey rounds, this analysis assesses the impact of dairy cow, meat goat, and draft cattle donation programs on poverty and food security measures. The impact on consumption expenditures and livestock revenue are estimated with a difference-in-difference method, and the impact on dairy/meat consumption frequency is estimated with a pooled poisson regression. A probit model is used to estimate the effects on subjective measures of poverty and food security. Results show that the impact of the program has increased significantly over time and animal recipients are relatively feeling better. By the fourth round, all animal recipients have seen a significant increase in consumption expenditure, livestock revenue, and frequency of dairy/meat consumption. However, no significant impact exists on household asset ownership and growth. Although all the animal recipients have increased milk consumption, meat consumption has gone up among the goat beneficiaries only. While all three animal species contribute to increase consumption expenditures among animal recipients, only the draft cattle and dairy cow programs help increase revenue from livestock products. Likewise, the meat goat and dairy cow programs have contributed to food security through improved dietary diversity.

description: We report on deep VLT observations of the fields of two nearby, isolated millisecond pulsars PSR J1744-1134 and PSR J1024-0719. Both objects are old neutron stars with characteristic age $τ\ge 10^9$ yr and have relatively high spin-down flux. They have been detected earlier as X-ray sources by ROSAT HRI observations and were considered good candidates for non-thermal emission in the optical bands. Our observations set an upper limit of $B=26.9$, $V=26.3$ and $R=26.0$ for PSR J1744-1134. In the case of PSR J1024-0719, we find two faint objects near the radio position of the pulsar. Using multi-band photometry from the VLT and spectroscopy carried out with the Magellan I telescope, we discuss the nature of the brighter object and the possibility of the fainter one being the optical counterpart of PSR J1024-0719. We consider the implications of our findings for both pulsars in the context of theoretical models of high-energy emission from old pulsars.

description: Many markets include communication forums (e.g. Angie's List for services, Yelp for restaurants) to facilitate trading between buyers and sellers. Some market-makers go beyond creating forums and make investments to improve the quality of communication platforms, such as by recruiting “elite” yelp members or Amazon Vine Program reviewers, in order to introduce more truthful reviews. We conduct an experiment in order to examine who benefits from providing communication forums and under what conditions should a market-maker invest in better communication. When third-party enforcement for quality is unavailable, theory predicts that communication will be especially important to facilitate reputation incentives to substitute for lack of contract enforceability. In our control treatment, buyers and sellers trade using imperfectly enforced contracts with no communication between the parties. Then we introduce two treatments with structured communication where subjects can endogenously choose to send pre-selected messages about their transaction (e.g. “the seller did not deliver desired quality”). We allow for two different types of communication: (a) send any pre-selected message regardless of trading outcomes, or (b) only send truthful messages. Our results show that compared to the control treatment, the addition of unverified communication does not have a significant impact on efficiency or social surplus, perhaps due to seller dishonesty in the communication system. Income distribution becomes more equitable, however, suggesting that unverified communication is an overall beneficial tool for development. We also find that there is much to gain from investments in improving communication over simply providing an opportunity for communication. Verifiable communication yields large increases in efficiency, and social surplus. It also alleviates, albeit mildly, income inequalities between buyers and sellers.

description: Weak interactions form the core basis of a vast number of biological processes, in particular, those involving intrinsically disordered proteins. Here, we establish a new technique capable of probing these weak interactions between synthetic unfolded polypeptides using a convenient yet efficient, quantitative method based on single particle tracking of peptide-coated gold nanoparticles over peptide-coated surfaces. We demonstrate that our technique is sensitive enough to observe the influence of a single amino acid mutation on the transient peptide-peptide interactions. Furthermore, the effects of buffer salinity, expected to alter weak electrostatic interactions, are also readily detected and examined in detail. The method presented here has the potential to evaluate in a high throughput manner, weak interactions for a wide range of disordered proteins, polypeptides, and other biomolecules.

description: The macroscopic quantum tunneling between two coupled Bose-Einstein condensates (BEC) (radio-frequency coupled two-component BECs or two BECs confined in a double-well potential) is mapped onto the tunneling of an uniaxial spin with an applied magnetic field. The tunneling exponent is calculated with an imaginary-time path-integral method. In the limit of low barrier, the dependence of tunneling exponent on the system parameters is obtained, and the crossover temperature from thermal regime to quantum regime is estimated. The detailed information about the tunnelling will give help to control population conversion between coupled BECs and realize quantum computation with coupled BECs.

Exploring the Career Management Experiences of Female Middle Managers in the HR Profession through a Feminist Poststructuralist and Intersectional Lens
Creators: name: Yerby, Elaine
Publisher: name: University of East London
Year: 2019

description: This thesis explores the career management experiences of twenty-five female, middle managers in the HR profession working in a range of UK private, public and non-for-profit organisations. A feminist poststructuralist and intercategorical intersectional (McCall, 2005) lens of gender, ethnicity and class was applied to explore how gendered dominant discourses competed and were negotiated in the context of the career management experiences and outcomes of the women. The findings of this research contribute to what can be considered the relatively small body of academic literature that has examined the careers of HR managers and women in the HR profession. Arguably, surprisingly small due to the focus for continuing professional development and career management within the profession. The feminist poststructuralism and the intersectional lens applied here allowed for new insights into the career management experiences of the women from shifting and complex subject positions to be identified. In doing so, marginalised voices were foregrounded in the context of how gendered dominant professional discourses impacted their career management experiences in competing and affiliated ways, providing the opportunity for new reflections on the impact of discourses in profession. The key findings of the research revealed the gendered nature of mainstream HRM and diversity management discourses impacted the career management experiences of the women through the restricted opportunities for training, complex positioning of female role models within the profession, and restricted opportunities for career planning due to the pressures of managing in the middle and the HR generalist role. The intersectional lens of the research also allowed for counterintuitive localities of career management privilege to be identified from what initially could be considered marginalised positions.

description: The steady motion and deformation of a lipid-bilayer vesicle translating through a circular tube in low Reynolds number pressure-driven flow are investigated numerically using an axisymmetric boundary element method. This fluid-structure interaction problem is determined by three dimensionless parameters: reduced volume (a measure of the vesicle asphericity), geometric confinement (the ratio of the vesicle effective radius to the tube radius), and capillary number (the ratio of viscous to bending forces). The physical constraints of a vesicle -- fixed surface area and enclosed volume when it is confined in a tube -- determine critical confinement beyond which it cannot pass through without rupturing its membrane. The simulated results are presented in a wide range of reduced volumes [0.6, 0.98] for different degrees of confinement; the reduced volume of 0.6 mimics red blood cells. We draw a phase diagram of vesicle shapes and propose a shape transition line separating the parachute-like shape region from the bullet-like one in the reduced volume versus confinement phase space. We show that the shape transition marks a change in the behavior of vesicle mobility, especially for highly deflated vesicles. Most importantly, high-resolution simulations make it possible for us to examine the hydrodynamic interaction between the wall boundary and the vesicle surface at conditions of very high confinement, thus providing the limiting behavior of several quantities of interest, such as the thickness of lubrication film, vesicle mobility and its length, and the extra pressure drop due to the presence of the vesicle. This extra pressure drop holds implications for the rheology of dilute vesicle suspensions. Furthermore, we present various correlations and discuss a number of practical applications.

description: This paper surveys some of the key themes in European agricultural policy research in recent decades. It identifies three main drivers of this research: a gradual broadening of the scope of the discipline in response to changing political priorities and values; an enlarged toolbox of policy instruments that has raised new questions and required the development of new modes of analysis; and the availability of new data sources, increased computing power, as well as the introduction of new methodological advances from economics, statistics and psychology that have opened the way to new and more powerful analytical tools. Particular attention is paid to direct payments and agri-environment-climate measures as examples of new policy instruments that have driven the research agenda. The paper concludes by identifying requirements to ensure that agricultural policy research remains vibrant and relevant in the future.

description: In pursuit of understanding of the paradoxical success of the Adam-Gibbs equation in both experiment and computer simulation studies, we examine the relation between liquid behavior at constant pressure and constant volume and compare the inherent structures excitation profiles for the two cases. This allows us to extend qualitatively the recent correlation of kinetic and thermodynamic measures of fragility to constant volume systems. The decreased fragility at constant volume is understood in terms of the relation Cp >Cc(cp) > Cc(cv) > Cv. In the process, we find a parallel between the range of volumes, relative to the total excess volume, that are explored in the first few orders of magnitude of relaxation time increase, and the range of amorphous state inherent structure energies, relative to the total range, that are explored in ergodic computer simulations, which also cover only this limited range of relaxation time change. The question of whether or not fragile behavior is determined in the configurational or vibrational manifold of states is left unanswered in this work. However, the approximate proportionality of the configurational and total excess entropies that is needed to interpret the success of the Adam Gibbs equation (which has been questioned by other authors) is confirmed within the needed limits, using data from three different types of investigation: experiments (on Se), simulation (of water in the SPC-E model), and analytical models of both defect crystals and configurationally excited liquids. Some consequences of the abrupt increases in vibrational heat capacity at Tg implied by this proportionality, are discussed.

description: The rural development plans in Europe, within the provisions of Axis Two of the Common Agricultural Policy, consider the opportunity to protect and enhance “environmental-friendly” farming systems. The present paper describes the role of organic farming measures in the promotion and safeguard of the High Nature Value in Tuscany. Using National Census of Agriculture data (2010) a Probit model was adopted, in order to estimate the probability of program enrolment. After that, both control and treatment groups were constructed implementing a Propensity Score Approach: selecting 13 explanatory variables which are presupposed to be independent from the outcome variable, the two groups were built on the basis of the propensity scores. The aim should be to have two similar groups, for which the only difference is the treatment itself. In our study the treatment variable is the total area under organic agriculture, while the outcome is the High nature Value. After having controlled and achieved a good balancing between the covariates, the mean effect of the program participation on the treated (ATT) was computed. It is obtained as a difference between the averages of the two groups. The result unexpectedly reveals that AES have not a statistically significant impact on both fauna and flora biodiversity. However, these results must be interpreted with caution because both the type of data (we used cross-sectional data) and the assumptions on which the methodology is based could have a relevant effect on the final outcome.

Artificial Intelligence and Machine Learning Approach to Measuring Energy Consumption in Data Centre Facilities
Creators: name: Jayathilake, Sanjeewa
Publisher: name: University of East London
Year: 2019

description: Data centres are at the heart of the modern digital world; However, at the same time it accounts for 10% of the world electricity supply. To improve energy efficiency, measuring energy consumption is an important step. However, it is a challenging task, especially in small to medium-sized data centres. Due to the setup of such facilities, it is not always feasible to measure the energy consumption (e.g. due to being positioned in mixed use buildings). This research project addresses this problem by providing the tools and models to help estimate the energy consumption of data centres, with particular emphasis on smaller facilities. The work made two main novel contributions. First, energy models along with a web-based user-friendly tool were developed. The tool is capable of calculating energy consumption of each DC equipment type to then approximate the overall energy consumption of the facility. This tool is available for DC managers and operators. It uses publicly available benchmark data as input for the calculations. One of the limitations of the first set of models is their reliance on pre-existing data for specific hardware. However, there are many ways hardware can be configured, meaning benchmark data was not available to all types of servers. As such, the second research contribution was the design of new machine learning algorithms capable of predicting energy consumption of servers based on a small number of features within 12% error rate. An open source software tool, MALEP, was also developed based on the machine learning algorithms to automate the prediction of the energy consumption of any servers, irrespective of the presence of benchmark data. The software is made available open source under the GNU General Public Licence and downloadable from GitHub. Although this work focused on servers which account for the largest part of energy consumption in data centres, in future, we hope to extend this work to create such models for storage and networking equipment.
Conceptualising Relational Normality in Psychoanalytically-Informed Couple Psychotherapy
Creators: name: Cachia, Pierre
Publisher: name: University of East London
Year: 2019

description: A review of the psychotherapy literature highlighted an absence of publications exploring the conceptualisation of relational normality in adult couple relationships. This research set out to address this gap in theoretical and clinical reflection. The central aim was to contribute to an enriched understanding of the manner in which explicit theory-derived concepts and implicit notions of relational normality are applied in couple psychotherapy. A qualitative design was adopted. Twenty-seven psychoanalytically-trained couple psychotherapists participated in one of the four focus groups used for data collection. Thematic Analysis led to the identification of three main themes namely: Political, Indigenous to psychoanalysis and Non-native paradigms. The ‘Political’ theme refers to the discernment of who carries the responsibility to define relational normality. It captures the weighting couple psychotherapists give to their role and expertise, patients’ views and experience as well as socio-cultural imperatives. Additionally, it highlights how their discernment is complicated by a degree of ambivalence. The second theme, ‘Indigenous’ denotes how psychoanalytic thinking is brought to bear in evaluating the quality of dynamic processes within and between partners, their psychic capacities and the genesis of difficulty. Participants concurrently maintained the view that sub-optimal states are normal. The third theme ‘Non-native paradigms’ refers to ideas sourced from outside the psychoanalytic tradition highlighting the contribution made by statistical and medico-legal models of normality. The main strength of this research lies in having recruited a sizable number of highly experienced couple psychotherapists. Limitations relate to the poor representation in terms of gender and ethnicity. This study recommends further research on factors influencing the consideration of the three identified themes. The research outcomes can also inform future training of professionals. This study identifies how couple psychotherapists seek to move away from their initial, potentially biased appraisal of normality towards a sophisticated reflexive position. Holding rigidly to normative theory and personal belief is considered ineffectual. Conceptualising normality is not simply about discerning facts but involves the attainment of a sense of dynamic equilibrium between the multiple perspectives couple therapists contemplate.

description: We present photometric and kinematic evidence for the presence of stellar disks, seen practically edge-on, in two Fornax dwarf galaxies, FCC204 (dS0(6)) and FCC288 (dS0(7)). This is the first time such structures have been identified in Fornax dwarfs. FCC2088 has only a small bulge and a bright flaring and slightly warped disk that can be traced out to 23" from the center (2.05 kpc for H_0=75 km/s/Mpc). FCC204's disk can be traced out to 20" (1.78 kpc). This galaxy possesses a large bulge. These results can be compared to the findings of Jerjen et al. (2000) and Barazza et al. (2002) who discovered nucleated dEs with spiral and bar features in the Virgo Cluster.

Its canted antiferromagnetic phase can host exotic topological surface states with a Möbius twist that are protected by nonsymmorphic symmetry. Moreover, opposite surfaces hosting Möbius fermions are connected by one-dimensional chiral hinge modes, which offers the first material candidate of a higher-order topological Möbius insulator. We uncover a general mechanism to feasibly induce this exotic physics by applying a small in-plane magnetic field to the antiferromagnetic topological insulating phase of MnBi$_{2n}$Te$_{3n+1}$, as well as other proposed axion insulators. For other magnetic configurations, two classes of inversion-protected higher-order topological phases are ubiquitous in this system, which both manifest gapped surfaces and gapless chiral hinge modes. We systematically discuss their classification, microscopic mechanisms, and experimental signatures. Remarkably, the magnetic-field-induced transition between distinct chiral hinge mode configurations provides an effective "topological magnetic switch".

description: We introduce a massively parallel replica-exchange grand-canonical sampling algorithm to simulate materials at realistic conditions, in particular surfaces and clusters in reactive atmospheres. Its purpose is to determine in an automated fashion equilibrium phase diagrams for a given potential-energy surface (PES) and for any observable sampled in the grand-canonical ensemble. The approach enables an unbiased sampling of the phase space and is embarrassingly parallel. It is demonstrated for a model of Lennard-Jones system describing a surface in contact with a gas phase. Furthermore, the algorithm is applied to Si$_M$ clusters ($M=2, 4$) in contact with an H$_{2}$ atmosphere, with all interactions described at the \textit{ab initio} level, i.e., via density-functional theory, with the PBE gradient-corrected exchange-correlation functional. We identify the most thermodynamically stable phases at finite $T, p$(H$_{2}$) conditions.

description: We study associative memory neural networks based on the Hodgkin-Huxley type of spiking neurons. We introduce the spike-timing-dependent learning rule, in which the time window with the negative part as well as the positive part is used to describe the biologically plausible synaptic plasticity. The learning rule is applied to encode a number of periodical spatiotemporal patterns, which are successfully reproduced in the periodical firing pattern of spiking neurons in the process of memory retrieval. The global inhibition is incorporated into the model so as to induce the gamma oscillation. The occurrence of gamma oscillation turns out to give appropriate spike timings for memory retrieval of discrete type of spatiotemporal pattern. The theoretical analysis to elucidate the stationary properties of perfect retrieval state is conducted in the limit of an infinite number of neurons and shows the good agreement with the result of numerical simulations. The result of this analysis indicates that the presence of the negative and positive parts in the form of the time window contributes to reduce the size of crosstalk term, implying that the time window with the negative and positive parts is suitable to encode a number of spatiotemporal patterns. We draw some phase diagrams, in which we find various types of phase transitions with change of the intensity of global inhibition.

description: We estimate demand for food diversity in Central and Eastern Europe. Food diversity is a proxy for the quality of a diet and it is one of the measures of households’ food and nutritional security status. Using data from the Slovak Household Budget Survey, we estimate the impact of household’s income and other socio-economic and demographic characteristics on the demand for food diversity by standard OLS. To deal with the endogeneity problem as some important variables affecting demand for food diversity such as health status, preferences, etc. are not observed, we also apply 2SLS estimation method. Households’ expenditures on purchase of assets serve as a suitable instrumental variable in the 2SLS estimation. We find that households’ demand for food diversity has been increasing since 2004 reflecting mainly rising incomes in Slovakia in that period. Recent economic crisis had a negative impact on diversity of food consumption of the Slovak households’. We also find that the estimated income elasticities are understated by OLS approach and are greater when the income endogeneity issue is addressed. Demand for food diversity is significantly higher for urban households than for households living in rural areas. Demand for food diversity is also affected by individual characteristics of the household’s head, such as education level, age or employment status as well as by the regional characteristics.

description: Bars strongly influence the distribution of gas and stars within the central regions of their host galaxies. This is particularly pronounced in the star formation desert (SFD) which is defined as two symmetrical regions either side of the bar that show a deficit in young stars. Previous studies proposed that, if star formation is truncated because of the influence of the bar, then the age distribution of stars within the SFD could be used to determine the epoch of bar formation. To test this, we study the properties of SFDs in 6 galaxies from zoom-in cosmological re-simulations. Age maps reveal old regions on both sides of the bars, with a lack of stars younger than 10 Myr, confirming the SFD phenomenon. Local star formation is truncated in the SFDs because after the bar forms, gas in these regions is removed on 1 Gyr timescales. However, the overall age distribution of stars in the SFD does not show a sharp truncation after bar formation but rather a gradual downturn in comparison to that of the bar. This more subtle signature may still give information on bar formation epochs in observed galaxies, but the interpretation will be more difficult than originally hoped. The gradual drop in the SFD age distribution, instead of a truncation, is due to radial migration of stars born in the disk. The SFD is thus one of the only regions where an uncontaminated sample of stars only affected by radial migration can be studied.

description: Dynamics of an ensemble of $N$-unit FitzHugh-Nagumo (FN) neurons subject to white noises has been studied by using a semi-analytical dynamical mean-field (DMF) theory in which the original $2 N$-dimensional {\it stochastic} differential equations are replaced by 8-dimensional {\it deterministic} differential equations expressed in terms of moments of local and global variables. Our DMF theory, which assumes weak noises and the Gaussian distribution of state variables, goes beyond weak couplings among constituent neurons. By using the expression for the firing probability due to an applied single spike, we have discussed effects of noises, synaptic couplings and the size of the ensemble on the spike timing precision, which is shown to be improved by increasing the size of the neuron ensemble, even when there are no couplings among neurons. When the coupling is introduced, neurons in ensembles respond to an input spike with a partial synchronization. DMF theory is extended to a large cluster which can be divided into multiple sub-clusters according to their functions. A model calculation has shown that when the noise intensity is moderate, the spike propagation with a fairly precise timing is possible among noisy sub-clusters with feed-forward couplings, as in the synfire chain. Results calculated by our DMF theory are nicely compared to those obtained by direct simulations. A comparison of DMF theory with the conventional moment method is also discussed.

Propagation velocities of gas rings in collisional ring galaxies

description: The propagation velocity of the first gas ring in collisional ring galaxies, i.e. the velocity at which the maximum in the radial gas density profile propagates radially in the galactic disk, is usually inferred from the radial expansion velocity of gas in the first ring. Our numerical hydrodynamics modeling of ring galaxy formation however shows that the maximum radial expansion velocity of gas in the first ring ($v_{gas}$) is invariably below the propagation velocity of the first gas ring itself ($v_{ring}$). Modeling of the Cartwheel galaxy indicates that the outer ring is currently propagating at $v_{ring} \approx$ 100 km/s, while the maximum radial expansion velocity of gas in the outer ring is currently $v_{gas} \approx$ 65 km/s. Modeling of the radial B-V/V-K color gradients of the Cartwheel ring galaxy also indicates that the outer ring is propagating at $v_{ring} \ge $ 90 km/s. We show that a combined effect of inclination, finite thickness, and warping of the Cartwheel's disk might be responsible for the lack of angular difference in the peak positions found for the azimuthally averaged $Hα$, K and B surface brightness profiles of the Cartwheel's outer ring. Indeed, the radial $Hα$ surface brightness profiles obtained along the Cartwheel's major axis, where effects of inclination and finite thickness are minimized, do peak exterior to those at K- and B-bands. The angular difference in peak positions implies $v_{ring}$ = 110 km/s, which is in agreement with the model predictions. We briefly discuss the utility of radio continuum emission and spectral line equivalent widths for determining the propagation velocity of gas rings in collisional ring galaxies.
