Periodic and Periodic Phase-Reversal Broadside Scanning Leaky-Wave Antennas in Substrate Integrated Waveguide
Creators: name: Henry, Robert

Subjects: subject: Engineering--Electronics and Electrical
subject: Substrate Integrated Waveguide, Leaky Wave Antenna, Traveling Wave Array

description: In recent years the preferred solution for achieving broadside scanning LWA performance in substrate integrated waveguide (SIW) has been the composite right/left handed (CRLH) leaky wave antenna (LWA). This thesis offers an alternative approach by outlining the design and study of a new periodic LWA architecture that uses half-mode SIW (HMSIW) to feed an array of antipodal tapered slot antenna (ATSA) radiating elements. The new antenna was among the first SIW based periodic LWAs to address the open-stopband that typically hinders broadside radiation, and was the first to do so using a unit-cell matching technique. Additionally, a compact periodic phase-reversal architecture of the antenna is presented that allows the ATSA element spacing to be reduced, enabling design with a comparatively low substrate permittivity while maintaining grating lobe free scanning. This antenna was the first SIW based LWA to use the periodic phase-reversal technique.

description: Understanding the process of embryonic morphogenesis is one of the most important questions in developmental biology. Morphogenesis is an important process that allows an organism to develop its final body shape. In most organisms, embryos form a roughly spherical ball of cells, but its final shape requires precise morphogenic and molecular events that have several layers of regulation. In Caenorhabditis elegans, a smooth muscle-like contraction of an actin/myosin network in the epidermis mediates the elongation of a worm embryo from a ball of cells into a long, thin worm. In this system only the lateral epidermal cells contract, suggesting that a localized Rho GEF (guanine exchange factor), which is an activator of contraction, is involved in this process. The first project of this thesis focused on characterizing a previously identified Rho GEF encoded by RHo Guanine nucleotide exchange Factor 2 (rhgf-2) gene. Previous work has placed rhgf-2within the context of a genetic pathway, but further characterization during early embryogenesis has not been studied. I continued the characterization of RHGF-2 by determining its protein expression pattern during embryogenesis and found that although it is ubiquitously expressed, RHGF-2 expression in the lateral epidermal cells is both necessary and sufficient for morphogenesis. The maternal and zygotic expression of RHGF-2 was also determined. I found that maternal expression regulates the speed of cleavage furrows in the early embryo while zygotic expression mediates morphogenesis. Finally, I examined the actin dynamics and tissue specific activity of RHGF-2. A second project focused on identifying a new component of the elongation pathway. A suppressor screen performed by a previous lab member against a mel-11 elongation-defective mutant discovered many components of the embryonic elongation pathway as we know it today. However, one allele of an unknown gene that our lab has designated as sb89 was not identified. I identified the gene represented by the sb89 mutation as ZK185.1 by using a combination of traditional mapping techniques in combination with Whole Genome Sequencing (WGS).
Chemosensory context conditioning in Caenorhabditis elegans

Publisher: name: University of British Columbia
Year: 2010

description: These studies were designed to investigate how environmental cues are associated during a non-associative learning process by studying chemosensory context conditioning for habituation in the nematode Caenorhabditis elegans. In chemosensory context conditioning for habituation animals that are trained and tested in the presence of either a taste or smell context cue show greater retention of habituation to tap stimuli when compared to animals trained and tested in different environments. This thesis is based on the work of Rankin (2000), in which taste (sodium acetate) context conditioning of habituation, extinction and latent inhibition of the cue were demonstrated. Here, I have shown context conditioning for an olfactory chemosensory cue (diacetyl) and dissociated the taste and smell pathways for this form of learning. odr-7 worms, with non-functional AWA olfactory chemosensory neuron (that detects diacetyl), showed short-term context conditioning to the taste but not to smell; the reverse was true for osm-3 worms with non-functional taste chemosensory neurons. This dissociation allows me to distinguish learning genes from genes involved in the detection of taste or smell. I also demonstrated long-term associative memory (24h) for context conditioning; context conditioning did not enhance normal long-term habituation, however, it produced memory in a training procedure that normally does not produce memory. My results showed that glr-1 (an AMPA-type ionotropic glutamate receptor subunit) and nmr-1 (an NMDA-type ionotropic glutamate receptor subunit) mutant worms did not show either short- or long-term context conditioning. To identify one site of plasticity, I showed that NMR-1 in the RIM interneurons was critical to produce short-term olfactory context conditioning. These studies lay the foundation to elucidate the cellular mechanisms of non-associative and associative learning for both short- and long-term memory, and may provide insights into how interneurons integrate information from multiple sensory systems.

description: We propose an explicit model, where an axionic domain wall dynamically localizes a U(1)-component of a nonabelian gauge theory living in a 3+1 dimensional bulk. The effective theory on the wall is 2+1d Maxwell-Chern-Simons theory with a compact U(1) gauge group. This setup allows us to understand all key properties of MCS theory in terms of the dynamics of the underlying 3+1 dimensional gauge theory. Our findings can also shed some light on branes in supersymmetric gluodynamics.

description: We study flows and interface deformations produced by the scattering of a laser beam propagating through non-absorbing turbid fluids. Light scattering produces a force density resulting from the transfer of linear momentum from the laser to the scatterers. The flow induced in the direction of the beam propagation, called 'optical streaming', is also able to deform the interface separating the two liquid phases and to produce wide humps. The viscous flow taking place in these two liquid layers is solved analytically, in one of the two liquid layers with a stream function formulation, as well as numerically in both fluids using a boundary integral element method. Quantitative comparisons are shown between the numerical and analytical flow patterns. Moreover, we present predictive simulations regarding the effects of the geometry, of the scattering strength and of the viscosities, on both the flow pattern and the deformation of the interface. Finally, theoretical arguments are put forth to explain the robustness of the emergence of secondary flows in a two-layer fluid system.
A Hermeneutic Phenomenological Study: Understanding the Meaning of Hope for People with Medically Acquired Hepatitis C

description: The impact of hope on chronic illness has long been acknowledged, however the experiences of people with medically acquired hepatitis C have been neglected in the literature. The aim of this study was to understand the lived experience of the meaning of hope for people with medically acquired hepatitis C using Interpretive Phenomenological Analysis (Smith et al., 2009), a qualitative hermeneutic phenomenological methodology. Semi-structured interviews were conducted with three adults who acquired hepatitis C through blood transfusions and successfully completed antiviral treatment. Five overarching themes were identified and are presented. An interpretation of these Master themes revealed four sources of hope and three pathways to hope suggesting that the meaning of hope for people with medically acquired hepatitis C is a complex, dynamic, and personal process. Implications for future practice and future research are presented.

By applying a suitable transformation, we map the forced/damped Nonlinear Schrödinger (NLS) equation into the standard NLS with constant coefficients. The transformation is valid as long as |Γt| \ll 1, with Γ the growth/damping rate of the waves due to the wind/dissipation. Approximate rogue wave solutions of the equation are presented and discussed. The results shed some lights on the effects of wind and dissipation on the formation of rogue waves.

Continuity Through Change: Sustainability, Resilience and the Vocabulary of Paradox

Subjects: subject: Environmental Sciences

subject: paradox
subject: Implementation
subject: praxis

description: Sustainability and resilience face an implementation crisis. To address this I propose a vocabulary of paradox where the price of clarity is either paradoxical theory or thoughtless action. Praxis, understood as reflective practice and practical reflection, occurs in the ‘muddled middle’ as researchers and practitioners resolve experience into generalised paradox and dissolve it into specific action. In the vocabulary of paradox this is the paradox of praxis: knowledge gives action meaning and action gives knowledge meaning. Applying the vocabulary to sustainability and resilience, I propose that both can be understood as articulations of a paradoxical desire for both continuity and change in human social-ecological circumstances. I define sustainability as the continuity of valued attributes of human circumstances both by means of and in the midst of change. Sustainability is continuity through change. This definition emphasises values (what should continue and change), understanding (what does continue and change) and human agency (what can be influenced to continue and change). All three merge in the muddled middle of implementation and are paradoxical in theory; continuity requires change and change requires continuity. Implementation of sustainability and resilience initiatives necessarily invokes a first person perspective. Here I propose a third paradox, the paradox of people, whereby people both constrain and enable each other. I argue that paradoxical agency for sustainability and resilience can be articulated in terms of these three paradoxes of praxis, people and sustainability: knowing and doing, together and apart for continuity and change. Finally, I propose the role of a sustainability agent, understood as both a change agent and a continuity agent, to support the paradoxical agency of individuals and small groups as they implement sustainability and resilience initiatives. I argue that this approach to sustainability and resilience dissolves the implementation gap and provides a practical and empowering vocabulary to make sense of sustainability praxis. I support these arguments with examples drawn from experiential research and interviews with conservation and sustainability practitioners in the North East region of the small Caribbean island of Tobago, West Indies.

description: The end-to-end speech translation (E2E-ST) model has gradually become a mainstream paradigm due to its low latency and less error propagation. However, it is non-trivial to train such a model well due to the task complexity and data scarcity. The speech-and-text modality differences result in the E2E-ST model performance usually inferior to the corresponding machine translation (MT) model. Based on the above observation, existing methods often use sharingmechanisms to carry out implicit knowledge transfer by imposing various constraints. However, the final model often performs worse on the MT task than the MT model trained alone, which means that the knowledge transfer ability of this method is also limited. To deal with these problems, we propose the FCCL (Fine- and Coarse- Granularity Contrastive Learning) approach for E2E-ST, which makes explicit knowledge transfer through cross-modal multi-grained contrastive learning. A key ingredient of our approach is applying contrastive learning at both sentence- and frame-level to give the comprehensive guide for extracting speech representations containing rich semantic information.In addition, we adopt a simple whitening method to alleviate the representation degeneration in the MT model, which adversely affects contrast learning. Experiments on the MuST-C benchmark show that our proposed approach significantly outperforms the state-of-the-art E2E-ST baselines on all eight language pairs. Further analysis indicates that FCCL can free up its capacity from learning grammatical structure information and force more layers to learn semantic information.

description: The categorical semantics of reversible computing must be a category which combines the concepts of partiality and the ability to reverse any map in the category. Inverse categories, restriction categories in which each map is a partial isomorphism, provide exactly this structure. This thesis explores inverse categories and relates them to both quantum computing and standard non-reversible computing. The former is achieved by showing that commutative Frobenius algebras form an inverse category. The latter is by establishing the equivalence of the category of discrete inverse categories to the category of discrete Cartesian restriction categories — this is the main result of this thesis. This allows one to transfer the formulation of computability given by Turing categories onto discrete inverse categories.

description: Automated augmentation is an emerging and effective technique to search for data augmentation policies to improve generalizability of deep neural network training. Most existing work focuses on constructing a unified policy applicable to all data samples in a given dataset, without considering sample or class variations. In this paper, we propose a novel two-stage data augmentation algorithm, named Label-Aware AutoAugment (LA3), which takes advantage of the label information, and learns augmentation policies separately for samples of different labels. LA3 consists of two learning stages, where in the first stage, individual augmentation methods are evaluated and ranked for each label via Bayesian Optimization aided by a neural predictor, which allows us to identify effective augmentation techniques for each label under a low search cost. And in the second stage, a composite augmentation policy is constructed out of a selection of effective as well as complementary augmentations, which produces significant performance boost and can be easily deployed in typical model training. Extensive experiments demonstrate that LA3 achieves excellent performance matching or surpassing existing methods on CIFAR-10 and CIFAR-100, and achieves a new state-of-the-art ImageNet accuracy of 79.97% on ResNet-50 among auto-augmentation methods, while maintaining a low computational cost.

description: PROBA-3 - PRoject for OnBoard Autonomy is an ESA mission to be launched in 2022 where a spacecraſt is used as an external occulter (OSC-Occulter Spacecraſt), to create an artificial solar eclipse as observed by a second spacecraſt, the coronagraph (CSC-Coronagraph Spacecraſt). The two spacecraſts (SCs) will orbit around the Earth, with an highly elliptic orbit (HEO), with the perigee at 600 Km, the apogee at about 60530 Km and an eccentricity of 0.81. The orbital period is of 19.7 hours and the precise formation flight (within 1 mm) will be maintainedforabout6hours overthe apogee, in ordertoguarantee the observation ofthe solarcoronawith the required spatial resolution. The relative alignment ofthe two spacecraſts is obtained bycombining information from several subsystems. One ofthe most accurate subsystem (with accuracy >0.5 mm) is the Shadow Position Sensors (SPS), composed by eight photomultipliers installed around the entrance pupil of the CSC. The SPS will monitor the penumbra generated by the occulter spacecraſt, whose intensity will change according to the relative position ofthe two satellites. A dedicated algorithm has been developed to retrieve the displacementof the spacecraſts fromthe measurements ofthe SPS. Several tests are requiredin ordertoevaluate the robustness of the algorithm and its performances/results for different possible configurations. A soſtware simulator has been developed for this purpose. The simulator includes the possibility to generate synthetic 2-D penumbra profile maps or analyze measured profiles and run different versions ofthe retrieving algorithms, including the “on-board” version. In order to import the “as built” algorithms, the soſtware is coded using Matlab.

description: The consequences for youth with mental illness are particularly acute and many experience crises that precipitate admission to hospital. When these youth are discharged, continuity of care is a key factor in a positive transition experience. Following discharge, youth require a form of social scaffolding to help them transfer their adaptive coping and self-regulation skills from the cool cognition of the hospital to the potentially hot cognition of their community. Recent research on the brain has demonstrated the importance of neuroplasticity during the period between the onset of puberty and adulthood. This period may be viewed as a window of both risk and opportunity. Risk, because the young person’s ability to make rational decisions is often adversely affected by his or her intense emotions. Opportunity, because the rapid growth of the brain during adolescence is strongly affected by the youth’s social environment, and this growth does not wane until after young adulthood. Thus, an understanding of the process of self-regulation of youth with mental illness in the context of discharge is essential for a successful discharge transition program. And yet, literature on the process of self-regulation in the context of discharge from the perspective of youth with mental illness is lacking. Using a grounded theory approach, this research study revealed the challenges and strengths experienced by youth in this process. Potential implications for practice included identifying and implementing strategies for addressing gaps in current programs, and directions for future research were discussed.

description: We extend our investigation of backgrounds to new physics signals, following CMS's data-driven search for supersymmetry at the LHC. The aim is to use different sets of cuts in gamma + 3-jet production to predict the irreducible Z + 3-jet background (with the Z boson decaying to neutrinos) to searches with missing transverse energy + 3-jet signal topologies. We compute ratios of Z + 3-jet to gamma + 3-jet production cross sections and kinematic distributions at next-to-leading order (NLO) in alpha_s. We compare these ratios with those obtained using a parton shower matched to leading-order matrix elements (ME+PS). This study extends our previous work [arXiv:1106.1423 [hep-ph]] on the Z + 2-jet to gamma + 2-jet ratio. We find excellent agreement with the ratio determined from the earlier NLO results involving two instead of three jets, and agreement to within 10% between the NLO and ME+PS results for the ratios. We also examine the possibility of large QCD logarithms in these processes. Ratios of Z + n-jet to gamma + n-jet cross sections are plausibly less sensitive to such corrections than the cross sections themselves. Their effect on estimates of Z + 3-jet to gamma + 3-jet ratios can be assessed experimentally by measuring the gamma + 3-jet to gamma + 2-jet production ratio in search regions. We partially address the question of potentially large electroweak logarithms by computing the real-emission part of the electroweak corrections to the ratio using ME+PS, and find that it is 1% or less. Our estimate of the remaining theoretical uncertainties in the Z to gamma ratio is in agreement with our earlier study.

description: Motivated by recent logarithmic entropy of Ho$\check{r}$ava-Lifshitz gravity, we investigate Hawking radiation for Kehagias-Sfetsos black hole from tunneling perspective. After considering the effect of self-gravitation, we calculate the emission rate and entropy of quantum tunneling by using Kraus-Parikh-Wilczek method. Meanwhile, both massless and massive particles are considered in this letter. Interestingly, two types tunneling particles have the same emission rate $Γ$ and entropy $S_b$ whose analytical formulae are $Γ= \exp{[π(r_{in}^2 - r_{out}^2t)/2 + π/α\ln r_{in}/r_{out}]}$ and $S_b = A/4 + π/α\ln (A/4)$, respectively. Here, $α$ is the Ho$\check{r}$ava-Lifshitz field parameter. The results show that the logarithmic entropy of Ho$\check{r}$ava-Lifshitz gravity could be explained well by the self-gravitation, which is totally different from other methods. The study of this semiclassical tunneling process may shed light on the understand of Ho$\check{r}$ava-Lifshitz gravity.

description: The potential use of two commercial extractants, LIX 7950, a guanidine derivative, and LIX 7820, a solvent mixture of quaternary amine and nonylphenol, for recovery of copper and cyanide from waste cyanide solution has been investigated. Low equilibrium pH favors copper extraction while a high molar ratio of cyanide to copper depresses the copper loading. It is confirmed that Cu(CN)²⁻₃ is preferentially extracted over Cu(CN) ³⁻₄ and CN- by the extractants. Solvent extraction of the mixture of metal cyano complexes shows a selectivity order as follows: Zn > Ni > Cu > Fe. The presence of SO²⁻₄ or S₂O²⁻₃ shows an insignificant effect on copper extraction while SCN- ions may potentially compete for the available extractant with copper cyanide species and thus depress copper extraction significantly. Both extractants exhibit an affinity sequence as SCN- > CNO- > CN-> S₂O²⁻₃. The selectivity order of different anions with the extractants can be explained by the interrelated factors including anion hydration, charge density, compatibility of the formed complex with the organic phase and the geometry effect. The extraction of Cu(CN)²⁻₃ with LIX 7950 is exothermic with an enthalpy change (ΔH°) of -191 kJ/mol. The copper extraction with LIX 7820 has little change when the temperature is varied from 25 °C to 45 °C. For both extractants, the loaded copper and cyanide can be stripped efficiently by a moderately strong NaOH solution. Further increase in NaOH concentration results in the formation of a third phase. The presence of NaCN can facilitate stripping of the loaded copper and cyanide by favoring the formation of Cu(CN)³⁻₄ in the stripping solution. The important findings suggest a possible solution to the separation of metal cyanide species and free cyanide in the cyanide effluent. Both extractants can be used in a SX circuit for pre-concentrating copper into a small volume of strip solution which can be further treated by electrowinning, AVR, SART or similar processes to recover copper products and cyanide. The free cyanide will remain in the raffinate solution from solvent extraction circuit which allows for the potential recycling of the barren solution to the gold cyanidation process.

description: Measuring pain in non-human mammals such as rodents is challenging. Recently, spontaneous behaviours including facial expression and ultrasonic vocalisation have been proposed as novel, alternative measures of pain. The goal of this research was to evaluate the applicability of ultrasonic vocalisations, and the Rat Grimace Scale (a recently developed facial expression pain scale) during gas exposure (for euthanasia purposes) and in models of inflammatory and incisional pain. First, I found that ultrasonic vocalisations were emitted during carbon dioxide, but not during isoflurane exposure. Secondly, the Rat Grimace Scale was able to detect inflammatory and incisional pain in rats. Additionally, the pain score obtained using the Rat Grimace Scale corresponded with the findings of a conventional nociceptive test using von Frey filaments. My work contributes to the further understanding of ultrasonic communicative behaviour and facial expression of rats experiencing pain and the application of grimace scales in in-vivo biomedical research.

description: This thesis work provides a mixed integer programming model to help integrating the drilling operation and supplier selection in well drilling process of oil/gas production. The appropriate decisions on the services orders are taken based on three criteria including service duration, cost and timely deliverance. The schedule of drilling operation is based on regular working time and overtime. The research outcomes provide the optimal or rational solutions for the decisions on: supplier selection, regular working time vs. overtime planning for each activity, and the total project duration with the minimum total project cost. The two typical drilling operation project cases from a local oil/gas company are collected and conducted to validate the feasibility and effectiveness of the model. In the thesis, the conflicts and trade-offs on the business profits and project time control between the operator company and its suppliers are also discussed. To solve the problem resulted from divergent positions between the operator company and its suppliers, the sharing risk and incentive contract are suggested to be adopted by the operator companies in oil/gas production from other manufacturing research and applications. In short, this study is novel and beneficial for drilling project management as it could improve the performance of drilling operations and to integrate the activities of the suppliers.

description: We introduceDropDim, a structured dropout method designed for regularizing the self-attention mechanism, which is a key component of the transformer. In contrast to the general dropout method, which randomly drops neurons, DropDim drops part of the embedding dimensions. In this way, the semantic information can be completely discarded. Thus, the excessive coadapting between different embedding dimensions can be broken, and the self-attention is forced to encode meaningful featureswith a certain number of embedding dimensions erased. Experiments on a wide range of tasks executed on the MUST-C English-Germany dataset show that DropDim can effectively improve model performance, reduce over-fitting, and show complementary effects with other regularization methods. When combined with label smoothing, the WER can be reduced from 19.1% to 15.1% on the ASR task, and the BLEU value can be increased from26.90 to 28.38 on the MT task. On the ST task, the model can reach a BLEU score of 22.99, an increase by 1.86 BLEU points compared to the strong baseline.
The fractal bubble model with a cosmological constant

description: We generalize the fractal bubble model (FB), recently proposed in the literature as an alternative to the standard $Λ$CDM cosmology, to include a non-zero cosmological constant. We retain the same volume partition of voids and walls as the original FB model, and the same matching conditions for null geodesics, but do not include effects associated with a nonuniform time flow arising from differences of quasilocal gravitational energy that may arise in the coarse-graining process. The Buchert equations are written and partially integrated and the asymptotic behaviour of the solutions is given. For a universe with $Λ=0$, as it is the case in the FB model, an initial void fraction with hyperbolic curvature evolves in such a way that it asymptotically fills completely our particle horizon. Conversely, in presence of a non vanishing $Λ$, we show that this does not happen and the voids fill a finite fraction $f_{v_{\infty}}<1$, where the value of $(1-f_{v_{\infty}})$ is expected to depend on $Λ$ and the initial fraction $f_{vi}$ and also to be small. For its determination, a numerical integration of the equations is necessary. Finally, an interesting prediction of our model is a formula giving a minimum allowed value of present day dark energy as a function of the age of the universe and of the matter and curvature density parameters at our time.

A Comparative Study Of The Efficiency Of Urban Junction Layouts With Particular Reference To The A24/A205 Junction At Clapham.
Creators: name: Saied, Payman Omer
Publisher: name: London South Bank University
Year: 1991

description: This thesis examines alternatives with a view to increase the capacity of urban road junction in general and A24/A205 junction in Clapham in particular. Data were analysed with relation to various parameters such as saturation flow, capacity. RFC ratio, queues and delays. Traffic signal management schemes and physical alterations to the existing road system were chosen as short term and long term solutions. These hypothetical schemes were tested using OSCADY and ARCADY 2 computer programs. A combination of schemes (increasing number of lanes and early cut-off, traffic signal at roundabout) was also examined. In examining ways of improving the capacity of the existing junction (A24/A205) special attention was paid to land use, safety and cost.

description: Introduction :
 Acute bilateral vision loss in the absence of organic cause may suggest visual conversion disorder. Case report :
 Herein, the authors present a rare case of dysthymic disorder complicated with visual conversion disorder, presented as painless acute bilateral loss of vision. A series of ophthalmologic diagnostic tests including the anterior and posterior segment ocular examination, RAPD, fogging test, menace reflex, computed tomography and magnetic resonance imaging of the brain, visual evoked potential (VEP), and electroretinography (ERG) were found to be normal, despite patient having no perception to light. Upon referral to a trained psychiatrist, identification of significant psychological stressors was addressed with supportive pharmacotherapy, psychotherapy, psychoeducation and cognitive behavioural therapy, which gradually restored functional visual acuity. Discussion / Conclusion :
 Therefore, multidisciplinary approach in functional vision loss should be reinstituted early in therapy to avoid delay in management and clinical outcome. Disclaimer: Abstract text might vary slightly from what is displayed in the e-poster.

The Relationships Among Compact Stellar Systems: A Fresh View of Ultra Compact Dwarfs

description: We use a combined imaging and spectroscopic survey of the nearby central cluster galaxy, M87, to assemble a sample of 34 confirmed ultra compact dwarfs (UCDs) with half-light radii of >~ 10 pc measured from Hubble Space Telescope images. This doubles the existing sample in M87, making it the largest such sample for any galaxy, while extending the detection of UCDs to unprecedentedly low luminosities (MV = -9). With this expanded sample, we find no correlation between size and luminosity, in contrast to previous suggestions, and no general correlation between size and galactocentric distance. We explore the relationships between UCDs, less luminous extended clusters (including faint fuzzies), globular clusters (GCs), as well as early-type galaxies and their nuclei, assembling an extensive new catalog of sizes and luminosities for stellar systems. Most of the M87 UCDs follow a tight color-magnitude relation, offset from the metal-poor GCs. This, along with kinematical differences, demonstrates that most UCDs are a distinct population from normal GCs, and not simply a continuation to larger sizes and higher luminosities. The UCD color-magnitude trend couples closely with that for Virgo dwarf elliptical nuclei. We conclude that the M87 UCDs are predominantly stripped nuclei. The brightest and reddest UCDs may be the remnant nuclei of more massive galaxies while a subset of the faintest UCDs may be tidally limited and related to more compact star clusters. In the broader context of galaxy assembly, blue UCDs may trace halo build-up by accretion of low-mass satellites, while red UCDs may be markers of metal-rich bulge formation in larger galaxies.
