description: We study synchronization in populations of phase-coupled stochastic three-state oscillators characterized by a distribution of transition rates. We present results on an exactly solvable dimer as well as a systematic characterization of globally connected arrays of N types of oscillators (N=2, 3, 4) by exploring the linear stability of the nonsynchronous fixed point. We also provide results for globally coupled arrays where the transition rate of each unit is drawn from a uniform distribution of finite width. Even in the presence of transition rate disorder, numerical and analytical results point to a single phase transition to macroscopic synchrony at a critical value of the coupling strength. Numerical simulations make possible the further characterization of the synchronized arrays.

description: We investigate the spin-valley polarization in MoTe$_2$ monolayer on (111) and (001) surfaces of ferromagnetic semiconductor EuO based on first-principles calculations. We consider surface reconstructions for EuO(111). We find that there is no direct chemical bonding between the reconstructed EuO(111) and the MoTe$_2$ overlayer, in contrast to the case of the ideal EuO(111). However, there is a strong hybridization between the states of MoTe$_2$ and the substrate states, which has a substantial impact on the valleys. The valley polarization due to the magnetic proximity effect is dependent on the detail of the interface structure, which is in the range of a few meV to about 40 meV. These values are at least one order of magnitude smaller than that induced by the ideal EuO(111). When the MoTe$_2$ monolayer is interfaced with EuO(001), the valley polarization is about 3.2 meV, insensitive to the interface structure. By a low-energy effective Hamiltonian model, the effective Zeeman field induced by EuO(001) is about 27 T, comparable to that for WSe$_2$/EuS obtained by experiment.

Receptor and cellular mechanisms of antipsychotic drugs
Creators: name: Guo, Ningning
Publisher: name: University of British Columbia

description: The mechanisms contributing to the atypical clinical profile of clozapine remain uncertain. To address this question, Fos-immunostaining in combination with drug manipulation, brain lesions and in situ hybridization histochemistry were used to examine neurotransmitter systems involved in the effects of antipsychotic drugs. This research program employed these techniques (1) to determine receptor mechanisms mediating clozapine-induced c-fos expression in the forebrain and (2) to characterize the phenotypes of neurons targeted by clozapine and the typical antipsychotic haloperidol. In the first experiment, scopolamine, a muscarinic receptor antagonist, attenuated haloperidol-induced Fos immunoreactivity in the striatum. This suggests that haloperidolinduced Fos induction in the striatum is modulated by muscarinic cholinergic mechanisms, and that the antimuscarinic action of clozapine may contribute to its failure to increase Fos induction in the striatum. 5,7-dihydroxytryptamine lesions of the medial forebrain bundle or 6- hydroxydopamine lesions of the dorsal noradrenergic bundle produced extensive serotonin and noradrenaline depletions in the forebrain, respectively. However, neither type of lesion affected clozapine-induced c-fos expression in the rat forebrain, suggesting that neither serotonergic nor noradrenergic mechanisms are involved in this action of clozapine. 7-hydroxy-N,N-di-n-propyl-2-aminotetralin (7-OHDPAT), a D3 receptor-preferring agonist, attenuated clozapine-induced c-fos expression in the nucleus accumbens (NAc), lateral septum (LSN) and the major island of Calleja (ICjM), without affecting the medial prefrontal cortex (mPFC). Quinpirole, which has similar affinities for D3 and D4 receptors, produced a small but significant attenuation of clozapine's effects in the mPFC and blocked clozapine's actions in the ICjM, NAC and LSN. Given the different affinities of quinpirole and 7-OHDPAT for D2, D3 and D4 receptors, these data suggest that clozapine-induced c-fos expression in the ICjM, NAc and LSN is due to its antagonist actions at D3 receptors, while antagonist actions at D4 receptors may contribute, in part, to the Fos induction in the mPFC. In situ hybridization for D3 receptor mRNA confirmed that most of the clozapineinduced Fos positive neurons in the ICjM, and the majority in the NAc and LSN express D3 receptor mRNA. In contrast, haloperidol-induced Fos positive neurons rarely expressed D3 mRNA in any brain region. Further studies demonstrated that clozapine increased c-fos expression in both enkephalin (Enk) and dynorphin (Dyn) containing neurons in the NAc and LSN. Haloperidol also increased c-fos expression in Enk and Dyn neurons, albeit in a different pattern. This suggests that while some Enk and/or Dyn neurons targeted by clozapine express D3 receptors, others do not.

description: We study the arithmetic of Eisenstein cohomology classes (in the sense of G. Harder) for symmetric spaces associated to GL_2 over imaginary quadratic fields. We prove in many cases a lower bound on their denominator in terms of a special L-value of a Hecke character providing evidence for a conjecture of Harder that the denominator is given by this L-value. We also prove under some additional assumptions that the restriction of the classes to the boundary of the Borel-Serre compactification of the spaces is integral. Such classes are interesting for their use in congruences with cuspidal classes to prove connections between the special L-value and the size of the Selmer group of the Hecke character.

description: Although recent advances in simulating open quantum systems have lead to significant progress, the applicability of numerically exact methods is still restricted to rather small systems. Hence, more approximate methods remain relevant due to their computational efficiency, enabling simulations of larger systems over extended timescales. In this study, we present advances for one such method, namely the Numerical Integration of Schrödinger Equation (NISE). Firstly, we introduce a modified ensemble-averaging procedure that improves the long-time behavior of the thermalized variant of the NISE scheme, termed Thermalized NISE. Secondly, we demonstrate how to use the NISE in conjunction with (highly) structured spectral densities by utilizing a noise generating algorithm for arbitrary structured noise. This algorithm also serves as a tool for establishing best practices in determining spectral densities from excited state calculations along molecular dynamics or quantum mechanics/molecular mechanics trajectories. Finally, we assess the ability of the NISE approach to calculate absorption spectra and demonstrate the utility of the proposed modifications by determining population dynamics.

description: In this paper, we visit the thermodynamic criticality and thermodynamic curvature of the charged AdS black hole in a new phase space. It is shown that when the square of the total charge of the charged black hole is considered as a thermodynamic quantity, the charged AdS black hole also admits an van der Waals-type critical behavior without the help of thermodynamic pressure and thermodynamic volume. Based on this, we study the fine phase structures of the charged AdS black hole with fixed AdS background in the new framework. On the one hand, we give the phase diagram structures of the charged AdS black hole accurately and analytically, which fills up the gap in dealing with the phase transition of the charged AdS black holes by taking the square of the charge as a thermodynamic quantity. On the other hand, we analyse the thermodynamic curvature of the black hole in two coordinate spaces. The thermodynamic curvatures obtained in two different coordinate spaces are equivalent to each other and are also positive. Based on an empirical conclusion under the framework of thermodynamic geometry, we speculate that when the square of charge is treated as an independent thermodynamic quantity, the charged AdS black hole is likely to present a repulsive between its molecules. More importantly, based on the thermodynamic curvature, we obtain an universal exponent at the critical point of phase transition.

Supportive and unsupportive processes within the stress and coping context
Creators: name: Hemphill, Kenneth John
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation comprises three studies, and includes interview and questionnaire data from 446 people coping with different stressful life events, and 87 providers. Data were gathered from a community sample, undergraduates, and people with Myalgic Encephalomyelitis (M.E.) and their close others. The primary aims were to document exchanges between providers and recipients, and develop a framework within which to understand supportive and unsupportive behaviors. Five sets of antecedents were studied, including personality dimensions, need for assistance, symptoms, perceived causes of chronic illness, and constraints (attributions for unhelpful actions and factors that prevented more supportive exchanges). Three sets of consequences (number and type of responses, and awareness of unhelpful actions) and two moderating variables (stressor characteristics and source of support) were also investigated. Consistent with the traditional model of social support, different forms of emotional assistance were regarded as helpful across the three studies. Avoidance, provision of unwanted information, and minimization and maximization were considered to be universally unhelpful. In line with the specificity model, other forms of support, such as tangible and informational assistance, were mentioned as especially helpful or unhelpful depending upon characteristics of the stressor (such as physical incapacitation, controllability, or trajectory). Across the three studies, respondents mentioned attributions for unsupportive behaviors that emphasized causes that were benign such as ignorance/lack of knowledge or understanding, emotional difficulties, additional stressors, and overprotectiveness. Such benign attributions were offered to close others and relatives more often than to distant others, and were not specific to situations with which providers had little familiarity. Approximately half of recipients reported that they did not say or do anything in response to unwanted actions by providers, which is consistent with the notion that many people coping with stressful life events may be reluctant to share their negative feelings with others. When they were not reticent, participants' responses were consistent with maintenance of harmony or conflict avoidance perspectives. Thus, recipients said that they discussed the issue rationally, downplayed the problem, blocked communication, or agreed with providers. Few recipients indicated that they attempted to maintain freedom and autonomy through screaming or acting in a hostile manner toward providers. Limitations, practical implications, and areas for future research were discussed.

description: Due to the difficulty of replicating the real conditions during training, supervised algorithms for spacecraft pose estimation experience a drop in performance when trained on synthetic data and applied to real operational data. To address this issue, we propose a test-time adaptation approach that leverages the temporal redundancy between images acquired during close proximity operations. Our approach involves extracting features from sequential spacecraft images, estimating their poses, and then using this information to synthesise a reconstructed view. We establish a self-supervised learning objective by comparing the synthesised view with the actual one. During training, we supervise both pose estimation and image synthesis, while at test-time, we optimise the self-supervised objective. Additionally, we introduce a regularisation loss to prevent solutions that are not consistent with the keypoint structure of the spacecraft. Our code is available at: https://github.com/JotaBravo/spacecraft-tta.

description: By employing an expansion in terms of the inverse multipole number, we derive analytic expressions for the quasinormal modes (QNMs) of scalar, Dirac, and Maxwell perturbations in the Hayward black hole (BH) background. The metric has three interpretations: as a model for a radiating BH, as a quantum-corrected BH owing to the running gravitational coupling in the Asymptotically Safe Gravity, and as a BH solution in the Effective Field Theory. We show that the obtained compact analytical formulas approximate QNMs with remarkable accuracy for $\ell > 0$.

description: The constant increase of the plastic production over the world has become a serious problem, since most conventional plastic materials come from fossil resources and are not biodegradable. This causes significant plastics accumulation in the environment, whose end-life must be managed. An effective and eco-friendly approach to solve such problem is the use of biodegradable materials. Biopolymers such as poly(butylene succinate) (PBS), poly(butylene succinate-co-adipate) (PBSA), poly(caprolactone) (PCL), poly(lactic acid) (PLA) and poly(propylene carbonate) (PPC) are among the most promising biodegradable commercial polyesters thanks to their high susceptibility to hydrolytic enzymes and to many microorganisms naturally occurring in the environment. The current study is an investigation of the degradation ability of several hydrolytic enzymes (i.e. lipase, esterase, etc.) against some common aliphatic commercial polyesters. The degradation is studied through preliminary film opacity assay, then weight loss measurements were combined to other analyses (i.e., GPC, 1H NMR, FT-IR, DSC and TGA) performed on the residual solids of polyester films after treatment with the different enzymes, in order to understand molecular and chemical modifications induced at the surface and/or in the bulk of polymer materials over time. The results showed that the enzymatic degradation occurred homogenously from the surface through an erosion mechanism and involved both the amorphous and the crystalline regions. Cleaving action mode for each enzyme (endo- and/or exo-type) is also proposed.

description: We investigate the dependence of the fidelity of a Mach-Zehnder quantum interferometer on the prior information about the phase, for Fock state input and for maximally entangled (N00N) state input. For no prior information, the fidelity for Fock state input is greater than for N00N state input. In the limit of a narrow distribution describing the prior information, we find that both Fock and N00N state inputs lead to nearly equal fidelity.

description: Spatial light modulators (SLMs) are popular tools for generating structured light fields and have fostered numerous applications in optics and photonics. Here, we explore the limits of what fields these devices are capable of generating and detecting in the context of so-called vortex beams carrying orbital angular momentum (OAM). Our main contributions are to quantify (theoretically and experimentally) how the pixelation of the SLM screen affects the quality of the generated vortex mode and to offer useful heuristics on how to optimise the performance of the displayed digital hologram. In so doing, we successfully generate and detect a very high order optical vortex mode with topological charge $\ell = 600$, the highest achieved to date using SLMs. Since the OAM degree of freedom is frequently touted as offering a potentially unbounded state space, we hope that this work will inspire researchers to make more use of higher order vortex modes.

description: With increasing attention to skin health, research has shifted from plant extracts to probiotics. Lactiplantibacillus plantarum BGI-N6 shows significant potential in skin health. This study explores its probiotic properties through complete genome analysis and in vitro experiments. The BGI-N6 genome spans 3,257,641 bases with a 45% GC content and 3,030 CDSs. The carbon source fermentation, gastrointestinal tolerance, and environmental adaptability provide a basis for colonization in skin and gut. Additionally, the skin-beneficial properties of BGI-N6 stem from antioxidant and enzyme inhibition capabilities, involving the glutathione system, thioredoxins/thioredoxin peroxidase, NADH peroxidase, and catalase. Additionally, organic acids like L-(+)-lactic acid and phenyllactic acid may play roles in antioxidant and enzyme inhibition. Further, in vitro experiments confirm its antioxidant capacity and enzyme inhibition capabilities. In conclusion, BGI-N6 improves skin conditions through antioxidant stress and enzyme inhibition, with potential in skincare development and dermatological adjuvant therapy.

description: In this contribution, we consider the equivalence between $f(R)$ gravity and scalar-tensor theories to study the evolution of scalar cosmological perturbations in the $1 + 3$ covariant formalism for the classes of shear-free cosmological dust models with irrotational fluid flows. The $f(R)$ gravity is considered to be a subclass of Brans-Dicke models, we gave an overview on the equivalence between $f(R)$ gravity and scalar-tensor theories. We use the $1 + 3$ covariant formalism to present the covariant linearised evolution and constraint equations. We then derive the integrability conditions describing a consistent evolution of the linearised field equations of quasi-Newtonian universes in the scalar-tensor theories of gravity. Finally, we derive the evolution equations for the density and velocity perturbations of the quasi-Newtonian universe. We apply the harmonic decomposition and we explore the behaviour of the matter density contrast by considering $R^{n}$ models. We introduce the so-called quasi-static approximation to study the approximated solutions on small scales. The growth of the matter density contrast for both short- and long- wavelength modes has been examined by applying certain assumptions of the initial conditions.

description: All-sky observations of the Milky Way show both Galactic and non-Galactic diffuse emission, for example from interstellar matter or the cosmic microwave background (CMB). The different emitters are partly superimposed in the measurements, partly they obscure each other, and sometimes they dominate within a certain spectral range. The decomposition of the underlying radiative components from spectral data is a signal reconstruction problem and often associated with detailed physical modeling and substantial computational effort. We aim to build an effective and self-instructing algorithm detecting the essential spectral information contained Galactic all-sky data covering spectral bands from $γ$-ray to radio waves. Utilizing principles from information theory, we develop a state-of-the-art variational autoencoder specialized on the adaption to Gaussian noise statistics. We first derive a generic generative process that leads from a low-dimensional set of emission features to the observed high-dimensional data. We formulate a posterior distribution of these features using Bayesian methods and approximate this posterior with variational inference. The algorithm efficiently encodes the information of 35 Galactic emission data sets in ten latent feature maps. These contain the essential information required to reconstruct the initial data with high fidelity and are ranked by the algorithm according to their significance for data regeneration. The three most significant feature maps encode astrophysical components: (1) The dense interstellar medium (ISM), (2) the hot and dilute regions of the ISM and (3) the CMB. The machine-assisted and data-driven dimensionality reduction of spectral data is able to uncover the physical features encoding the input data. Our algorithm is able to extract the dense and dilute Galactic regions, as well as the CMB, from the sky brightness values only.

description: We have theoretically examined the size dependence of the equilibrium lattice constant of nanocrystals of Si, GaAs and CdSe. While deviations from the bulk lattice constant are as large as 1-2% for unpassivated nanocrystals of Si, the deviations drop to ~ 0.3%-0.4% once the surfaces are passivated. Inspite of the fact that the average equilibrium bond-lengths are bulk-like, we find that the nearest-neighbor bond-length exhibits an unusual strain profile with bulk like bond-lengths in the core and shorter (~ 1%) bonds at the surface.

description: From a sample of 32 GRBs with known redshift (Guidorzi et al. 2005) and then a sample of 551 BATSE GRBs with derived pseudo-redshift (Guidorzi 2005), the time variability/peak luminosity correlation (V vs. L) found by Reichart et al. (2001) was tested. For both samples the correlation is still found but less relevant due to a much higher spread of the data. Assuming a straight line in the logL-logV plane (logL = m logV + b), as done by Reichart et al., the slope was found lower than that derived by Reichart et al.: m = 1.3_{-0.4}^{+0.8} (Guidorzi et al. 2005), m = 0.85 +- 0.02 (Guidorzi 2005), to be compared with m = 3.3^{+1.1}_{-0.9} (Reichart et al. 2001). Reichart & Nysewander (2005) attribute the different slope to the fact we do not take into account in the fit the variance of the sample, and demonstrate that, using the method by Reichart (2001), the data set of Guidorzi et al. (2005) in logL-logV plane is still well described with slope m = 3.4^{+0.9}_{-0.6}. Here we compare the results of two methods accounting for the variance of the sample, that implemented by Reichart (2001) and that by D'Agostini (2005). We demonstrate that the method by Reichart (2001) provides an inconsistent estimate of the slope when the sample variance is comparable with the interval of values covered by the variability. We also show that, using the D'Agostini method, the slope is consistent with that derived by us earlier and inconsistent with that derived by Reichart & Nysewander (2005). Finally we discuss the implications on the interpretations and show that our results are in agreement with the peak energy/variability correlation found by Lloyd-Ronning & Ramirez-Ruiz (2002) and the peak energy/peak luminosity correlation (Yonetoku et al. 2004; Ghirlanda et al. 2005) [abridged].

description: We analyze the collective mode spectrum of graphene nanoribbons within the random phase approximation. In the undoped case, only metallic armchair nanoribbons support a propagating plasmon mode. Landau damping of this mode is shown to be suppressed through the chirality of the single particle wavefunctions. We argue that undoped zigzag nanoribbons should not support plasmon excitations because of a broad continuum of particle-hole excitations associated with surface states, into which collective modes may decay. Doped nanoribbons have properties similar to those of semiconductor nanowires, including a plasmon mode dispersing as $q\sqrt{-\ln qW}$ and a static dielectric response that is divergent at $q=2k_F$.

description: The late-stage ordering of interacting magnetic skyrmions is studied numerically through extensive Langevin molecular dynamics simulations. Defining skyrmion displacements that change the connectivity of cells obtained in a Voronoi tesselation as events, we investigate event histograms as a function of the time elapsed since preparing the system as well as the histograms of consecutive events as a function of the time separating these two events. These histograms, which provide unique insights into the transient properties during the ordering process of skyrmion matter, show a characteristic behavior that allows the Magnus-force dominated regime, where the Magnus force accelerates the relaxation process, to be distinguished from the noise-dominated regime, where the Magnus force enhances the effects of thermal noise. In the Magnus-force dominated regime the different histograms display power-law tails with exponents that depend on the strength of the Magnus force.

description: We analyze the structure of a particular higher derivative correction of five-dimensional ungauged and gauged supergravity with eight supercharges. Specifically, we determine all the purely bosonic terms which are connected by the supersymmetry transformation to the mixed gauge-gravitational Chern-Simons term, W wedge tr R wedge R. Our construction utilizes the superconformal formulation of supergravity. As an application, we determine the condition for the supersymmetric anti-de Sitter vacuum with this term. We check that it gives precisely the same condition as the a-maximization in four-dimensional superconformal field theory on the boundary, as predicted by the AdS/CFT correspondence.

description: Coexistence of topological bands and charge density wave (CDW) in topological materials has attracted immense attentions because of their fantastic properties, such as axionic-CDW, three-dimensional quantum Hall effect, etc. In this work, a nodal-line semimetal InxTaS2 characterized by CDW and superconductivity is successfully synthesized, whose structure and topological bands (two separated Wely rings) are similar to In0.58TaSe2. A 2 x 2 commensurate CDW is observed at low temperature in InxTaS2, identified by transport properties and STM measurements. Moreover, superconductivity emerges below 0.69 K, and the anisotropy ratio of upper critical field [Gamma = H||ab c2(0)=H||c c2(0)] is significantly enhanced compared to 2H-TaS2, which shares the same essential layer unit. According to the Lawrence-Doniach model, the enhanced Gamma may be explained by the reduced effective mass in kx-ky plane, where Weyl rings locate. Therefore, this type of layered topological systems may offer a platform to investigate highly anisotropic superconductivity and to understand the extremely large upper critical field in the bulk or in the two-dimensional limit.

Polarisation of mJy radio sources

description: Predictions of the number of faint polarised radio sources that can be detected by SKA pathfinder telescopes and the SKA depend on the polarisation properties of radio sources with a total flux density around 1 mJy. Total intensity source counts suggest a transition in the dominant population from AGN to galaxies around this flux density, and the properties of brighter radio sources may not be representative for this fainter population. We show that unresolved spiral galaxies can be highly polarised radio sources, up to ~ 20% polarised at 4.8 GHz. This result is partly based on observations of nearby galaxies, including galaxies with significant deviations from axial symmetry and other peculiarities. A first analysis of polarised source counts divided into steep-spectrum AGN, flat-spectrum AGN and star forming galaxies is presented, including a prediction of polarised source counts to microjansky levels.

description: Recent study suggests that there are natural connections between quantum information theory and the Yang--Baxter equation. In this paper, in terms of the generalized almost-complex structure and with the help of its algebra, we define the generalized Bell matrix to yield all the GHZ states from the product base, prove it to form a unitary braid representation and present a new type of solution of the quantum Yang--Baxter equation. We also study Yang-Baxterization, Hamiltonian, projectors, diagonalization, noncommutative geometry, quantum algebra and FRT dual algebra associated with this generalized Bell matrix.

Liouville field theory for gluon saturation in QCD at high energy

description: We argue that quantum Liouville field theory supplemented with a suitable source term is the effective theory which describes the short-range correlations of the gluon saturation momentum in the two-dimensional impact-parameter space, at sufficiently high energy and for a large number of colors. This is motivated by recent developments concerning the stochastic aspects of the high-energy evolution in QCD, together with the manifest scale invariance of the respective evolution equations and general considerations on the uncertainty principle. The source term explicitly breaks down the conformal symmetry of the (pure) Liouville action, thus introducing a physical mass scale in the problem which is identified with the average saturation momentum. We construct this source term for the case of a homogeneous distribution and show that this leads to an interesting theory: the relevant correlation functions are ultraviolet finite (and not just renormalizable) when computed in perturbation theory, due to mutual cancellations of the tadpole divergences. Possible generalizations to inhomogeneous source terms are briefly discussed.

description: The Navier slip condition describes the motion of a liquid, relative to a neighboring solid surface, with its characteristic Navier slip length being a constitutive property of the solid-liquid interface. Measurement of this slip length is complicated by its small magnitude, expected in the nanometer range based on molecular simulations. Here, we report an experimental technique that interrogates the Navier slip length on individual nanoparticles immersed in liquid, with sub-nanometer precision. Proof-of-principle experiments on individual, citrate-stabilized, gold nanoparticles in water give a constant slip length of 2.7$\pm$0.6 nm (95% C.I.) - independent of particle size. Achieving this feature of size independence is central to any measurement of this constitutive property, which is facilitated through the use of individual particles of varying radii. This demonstration motivates studies that can now validate the wealth of existing molecular simulation data on slip.

Quasiperiodicity, band topology, and moiré graphene

description: A number of moiré graphene systems have nearly flat topological bands where electron motion is strongly correlated. Though microscopically these systems are only quasiperiodic, they can typically be treated as translation invariant to an excellent approximation. Here we reconsider this question for magic angle twisted bilayer graphene that is nearly aligned with a hexagonal boron nitride(h-BN) substrate. We carefully study the effect of the periodic potential induced by h-BN on the low energy physics. The combination of this potential and the moiré lattice produced by the twisted graphene generates a quasi-periodic term that depends on the alignment angle between h-BN and the moiré graphene. We find that the alignment angle has a significant impact on both the band gap near charge neutrality and the behavior of electrical transport. We also introduce and study toy models to illustrate how a quasi-periodic potential can give rise to localization and change in transport properties of topological bands.

Platelets : their exploitation and elimination

description: Platelets are cytoplasmic fragments present in large numbers within the bloodstream that contain a multitude of proteins. For a long time, platelet function was believed to be limited to the essential functions of haemostasis and thrombosis. However, it has become clear in the last decade that platelets play significant roles in both innate and adaptive immunity, inflammatory responses including leukocyte migration, tissue regeneration and angiogenesis. Parallelling the revelation of the diverse physiological functions of platelets, however, has been the association of exacerbated platelet function with numerous thrombotic and chronic inflammatory diseases. Until our knowledge of platelet biology is more comprehensive, the prevention of platelet-associated pathologies will remain a challenge of inhibiting pathology-associated platelet reactions whilst preserving those essential for normal function. The aims of this thesis, therefore, were to examine in detail the following three platelet-associated biological processes: (i) The role of platelets in tumour cell metastasis, in particular, the kinetics and interrelationship of the pro-metastatic role of platelets and the anti-metastatic role of NK cells, and the relevant contributions to the metastatic process of platelet P-selectin and endothelial P-selectin. (ii) The determinants and mechanisms of antibody-mediated platelet elimination, as seen in the medical condition known as immune thrombocytopenic purpura (ITP), and the role of inhibitory self-recognition systems in this process. (iii) The factors influencing platelet and erythrocyte lifespan by establishing appropriate experimental and analytical methodologies.
