description: Findings from this study examining Australian optometrists’ insights into ocular stem cell (SC) therapies have capacity to inform continuing professional development (CPD) about these interventions. This study investigated Australian optometrists’ knowledge, views, experiences, and preferred education sources regarding ocular SC therapies. An online survey was distributed to optometrists via Optometry Australia, Mivision magazine, professional groups, and social media from August 2020 to March 2021. Data were collected on demographics, and SC knowledge, awareness and experience. Of 81 optometrists who completed the survey, many were metropolitan-based (85%), worked in independent practice (47%), female (56%) and >46 years of age (45%). Approximately one-fifth indicated awareness of ocular SC therapies used in standard practice; one-third had knowledge of SC clinical trials. The most noted SC therapies were for corneal disease in the United States [US] (72%) and Australia (44%). Respondents identified the availability of SC therapies for dry eye disease in Australia and the US (39% and 44% respectively), despite no regulatory-approved treatments for this indication. Clinical trials investigating inherited retinal and corneal diseases in Australia were the most commonly identified (44% and 36%, respectively). Half the respondents felt ‘unsure’ about the quality of evidence for treating eye conditions using SCs. One-fifth indicated concerns with these therapies; of these, most mentioned efficacy (82%), safety (76%) and/or cost (71%). About one-fifth reported being asked for advice about SCs by patients. Two-thirds felt neutral, uncomfortable, or very uncomfortable providing this advice, due to lack of knowledge or the topic being beyond their expertise. Over half (57%) were unsure if clinical management should change if patients received SC therapies. Respondents were receptive to face-to-face education. Some optometrists responding to this survey were aware of ocular SC therapies and/or clinical trials. CPD programs may assist with maintaining currency in this evolving field.

description: The support of students with a vision impairment throughout education could be enhanced by assessing the functional reading ability of the individual. This visual assessment could inform educators of individualised student needs and potentially improve the academic achievement for these students. Support for children with a vision impairment within a classroom is typically based on clinical findings of distance visual acuity and visual fields. Therefore, determining optimal print size for reading is essential to ensure best academic outcomes. Secondary aims were to investigate the possible impact of underlying pathology on reading ability. Forty-seven participants were recruited from a state-wide support service for children with a vision impairment in South Australia. Three visual acuity groups were formed based on World Health Organisation definitions of mild, moderate, and severe vision impairment. Correlation between clinical measures of distance visual acuity using the Freiburg Visual Acuity Test, were compared with reading acuity and critical print size (smallest font before reading speed reduced) using Minnesota low vision reading chart (MNREAD). No significant correlations were found for mild (0.20–0.49 logMAR) and severe (1.00–1.52 logMAR) vision impairment groups between distance visual acuity and reading acuity read (p = .64, CI [−.585, .395]/p = .82, CI [−.48, .58]) or critical print size (p = .78, CI [−.57, .45]/p = .43, CI [−.34, .68]. A significant correlation was found for the moderate vision impairment group: 0.50–0.99 logMAR for minimum reading acuity (p < .001, CI [.44, .91]) and critical print size (p = .03, CI [.05, .80]). Standard clinical measures of distance visual acuity are an unpredictable estimate of reading ability in children with mild and severe vision impairment. Additional measures of functional near reading ability could provide a more meaningful indicator of reading ability and help provide optimum support to students through education.

description: We introduce two information-theoretical invariants for the projective unitary group acting on a finite-dimensional complex Hilbert space: PVM- and POVM-dynamical (quantum) entropies. They quantify the randomness of the successive quantum measurement results in the case where the evolution of the system between each two consecutive measurements is described by a given unitary operator. We study the class of chaotic unitaries, i.e., the ones of maximal entropy or, equivalently, such that they can be represented by suitably rescaled complex Hadamard matrices in some orthonormal bases. We provide necessary conditions for a unitary operator to be chaotic, which become also sufficient for qubits and qutrits. These conditions are expressed in terms of the relation between the trace and the determinant of the operator. We also compute the volume of the set of chaotic unitaries in dimensions two and three, and the average PVM-dynamical entropy over the unitary group in dimension two. We prove that this mean value behaves as the logarithm of the dimension of the Hilbert space, which implies that the probability that the dynamical entropy of a unitary is almost as large as possible approaches unity as the dimension tends to infinity.

description: The stochastic dynamics of biochemical networks are usually modelled with the chemical master equation (CME). The stationary distributions of CMEs are seldom solvable analytically, and numerical methods typically produce estimates with uncontrolled errors. Here, we introduce mathematical programming approaches that yield approximations of these distributions with computable error bounds which enable the verification of their accuracy. First, we use semidefinite programming to compute increasingly tighter upper and lower bounds on the moments of the stationary distributions for networks with rational propensities. Second, we use these moment bounds to formulate linear programs that yield convergent upper and lower bounds on the stationary distributions themselves, their marginals and stationary averages. The bounds obtained also provide a computational test for the uniqueness of the distribution. In the unique case, the bounds form an approximation of the stationary distribution with a computable bound on its error. In the non-unique case, our approach yields converging approximations of the ergodic distributions. We illustrate our methodology through several biochemical examples taken from the literature: Schlögl's model for a chemical bifurcation, a two-dimensional toggle switch, a model for bursty gene expression, and a dimerisation model with multiple stationary distributions.

description: About 15 years ago, Bismut gave a natural construction of a Hodge theory for a hypoelliptic Laplacian acting on the total space of the cotangent bundle of a Riemannian manifold. This operator interpolates between the classical elliptic Laplacian on the base and the generator of the geodesic flow. We will describe recent developments of the theory of hypoelliptic Laplacians, in particular the explicit formula obtained by Bismut for orbital integrals and the recent solution by Shen of Fried's conjecture (dating back to 1986) for locally symmetric spaces. The conjecture predicts the equality of the analytic torsion and the value at 0 of the dynamic zeta function.

description: This study aims to develop a health behavior model for females with a history of gestational diabetes mellitus (GDM) to promote healthy dietary habits and glucose tolerance testing by identifying factors affecting the health behaviors of this population based on the framework of the Theory of Planned Behavior. A questionnaire survey was administered to females with a history of GDM who were raising infants, and 58 responses were analyzed. An exploratory factor analysis using Promax rotation was conducted to determine the factor structure of the influencing factors of each health behavior. Next, a structural analysis of covariance was conducted using each factor extracted from the factor analysis and "behavioral intention" and "behavior" as observed variables. The analyses identified six factors affecting health behaviors. Of these the following four factors affected “behavioral intentions” of healthy dietary habits: Having spare time in daily life, finding positive implications for healthy dietary habits, family understanding of postpartum healthcare, and feelings of ease about eating; also, feeling of ease about eating and “behavioral intentions” affect “behaviors.” For the factors affecting taking periodic glucose tolerance tests, four factors were identified, and of these the following three affected “behavioral intentions”: awareness of the necessity of taking the test, psychological burden of taking the test, and finding positive implications for taking the test. The “behavioral intentions” affected “behaviors.” These models yielded adequate goodness-of-fit indices, suggesting that interventions focusing on the factors affecting their respective health behaviors may contribute to the promotion of health behaviors

description: Answering queries over a federation of SPARQL endpoints requires combining data from more than one data source. Optimizing queries in such scenarios is particularly challenging not only because of (i) the large variety of possible query execution plans that correctly answer the query but also because (ii) there is only limited access to statistics about schema and instance data of remote sources. To overcome these challenges, most federated query engines rely on heuristics to reduce the space of possible query execution plans or on dynamic programming strategies to produce optimal plans. Nevertheless, these plans may still exhibit a high number of intermediate results or high execution times because of heuristics and inaccurate cost estimations. In this paper, we present Odyssey, an approach that uses statistics that allow for a more accurate cost estimation for federated queries and therefore enables Odyssey to produce better query execution plans. Our experimental results show that Odyssey produces query execution plans that are better in terms of data transfer and execution time than state-of-the-art optimizers. Our experiments using the FedBench benchmark show execution time gains of at least 25 times on average.

description: A number of proposals with differing predictions (e.g. Borel group cohomology, oriented cobordism, group supercohomology, spin cobordism, etc.) have been made for the classification of symmetry protected topological (SPT) phases. Here we treat various proposals on an equal footing and present rigorous, general results that are independent of which proposal is correct. We do so by formulating a minimalist Generalized Cohomology Hypothesis, which is satisfied by existing proposals and captures essential aspects of SPT classification. From this Hypothesis alone, formulas relating classifications in different dimensions and/or protected by different symmetry groups are derived. Our formalism is expected to work for fermionic as well as bosonic phases, Floquet as well as stationary phases, and spatial as well as on-site symmetries. As an application, we predict that the complete classification of 3-dimensional bosonic SPT phases with space group symmetry $G$ is $H^4_{\rm Borel}\left(G;U(1)\right) \oplus H^1_{\rm group}\left(G;\mathbb Z\right)$, where the $H^1$ term classifies phases beyond the Borel group cohomology proposal.

description: Amblyopia is the most frequent cause of monocular vision loss. Transcranial Magnetic Stimulation (TMS) has been used to improve several vision parameters of the amblyopic eye in adulthood. This study is relevant in order to evaluate TMS effects and to raise awareness of the need for further research. Transcranial Magnetic Stimulation (TMS) is a neuromodulation technique capable of changing cortical excitability. In the last decade, it has been used to improve visual parameters in amblyopic patients. The main goal of this systematic review is to evaluate the influence of TMS in the amblyopic eye, in the visual parameters of amblyopic patients. Searches were done in PubMed and Embase databases, and a combined search strategy was performed using the following Mesh, EMBASE, and keywords: ‘Amblyopia’, ‘Transcranial Magnetic Stimulation’, and ‘theta burst stimulation’. This review included randomised controlled studies, descriptive cases, and clinical case studies with adult amblyopes. All articles that had any of the following characteristics were excluded: children or animal studies, reviews, pathologies other than amblyopia, and other techniques rather than repetitive TMS (rTMS), or Theta Burst Stimulation (TBS). A total of 42 articles were found, of which only four studies (46 amblyopes) meet the criteria above. Three of the articles found significant improvement after one session of continuous TBS (cTBS) in visual parameters like visual acuity, contrast sensitivity, suppressive imbalance, and stereoacuity. One study found a significant visual improvement with 10 Hz rTMS. Only one stimulation-related dropout was reported. The few existing studies found in this review seem to show that through the usage of high-frequency rTMS and cTBS, it is possible to re-balance the eyes of an adult amblyope. However, despite the promising results, further research with larger randomised double-blind studies is needed for a better understanding of this process.

description: The focus of this paper is on co-existence between a communication system and a pulsed radar sharing the same bandwidth. Based on the fact that the interference generated by the radar onto the communication receiver is intermittent and depends on the density of scattering objects (such as, e.g., targets), we first show that the communication system is equivalent to a set of independent parallel channels, whereby pre-coding on each channel can be introduced as a new degree of freedom. We introduce a new figure of merit, named the {\em compound rate}, which is a convex combination of rates with and without interference, to be optimized under constraints concerning the signal-to-interference-plus-noise ratio (including {\em signal-dependent} interference due to clutter) experienced by the radar and obviously the powers emitted by the two systems: the degrees of freedom are the radar waveform and the afore-mentioned encoding matrix for the communication symbols. We provide closed-form solutions for the optimum transmit policies for both systems under two basic models for the scattering produced by the radar onto the communication receiver, and account for possible correlation of the signal-independent fraction of the interference impinging on the radar. We also discuss the region of the achievable communication rates with and without interference. A thorough performance assessment shows the potentials and the limitations of the proposed co-existing architecture.

description: A game is rigid if a near-optimal score guarantees, under the sole assumption of the validity of quantum mechanics, that the players are using an approximately unique quantum strategy. Rigidity has a vital role in quantum cryptography as it permits a strictly classical user to trust behavior in the quantum realm. This property can be traced back as far as 1998 (Mayers and Yao) and has been proved for multiple classes of games. In this paper we prove ridigity for the magic pentagram game, a simple binary constraint satisfaction game involving two players, five clauses and ten variables. We show that all near-optimal strategies for the pentagram game are approximately equivalent to a unique strategy involving real Pauli measurements on three maximally-entangled qubit pairs.

description: As CMOS scaling reaches its technological limits, a radical departure from traditional von Neumann systems, which involve separate processing and memory units, is needed in order to significantly extend the performance of today's computers. In-memory computing is a promising approach in which nanoscale resistive memory devices, organized in a computational memory unit, are used for both processing and memory. However, to reach the numerical accuracy typically required for data analytics and scientific computing, limitations arising from device variability and non-ideal device characteristics need to be addressed. Here we introduce the concept of mixed-precision in-memory computing, which combines a von Neumann machine with a computational memory unit. In this hybrid system, the computational memory unit performs the bulk of a computational task, while the von Neumann machine implements a backward method to iteratively improve the accuracy of the solution. The system therefore benefits from both the high precision of digital computing and the energy/areal efficiency of in-memory computing. We experimentally demonstrate the efficacy of the approach by accurately solving systems of linear equations, in particular, a system of 5,000 equations using 998,752 phase-change memory devices.
Coined Quantum Walks on Weighted Graphs

description: We define a discrete-time, coined quantum walk on weighted graphs that is inspired by Szegedy's quantum walk. Using this, we prove that many lackadaisical quantum walks, where each vertex has $l$ integer self-loops, can be generalized to a quantum walk where each vertex has a single self-loop of real-valued weight $l$. We apply this real-valued lackadaisical quantum walk to two problems. First, we analyze it on the line or one-dimensional lattice, showing that it is exactly equivalent to a continuous deformation of the three-state Grover walk with faster ballistic dispersion. Second, we generalize Grover's algorithm, or search on the complete graph, to have a weighted self-loop at each vertex, yielding an improved success probability when $l < 3 + 2\sqrt{2} \approx 5.828$.

description: The growing e-waste problem, fueled by high consumption of electronics and electrical equipment (EEE) and resource scarcity poses serious health, safety, and environmental risks. The circular economy (CE) is presented as a sustainable solution for these concerns, though some stakeholders may struggle with adapting to increased demands like supply chain transparency, materials traceability, and technological advancement. Operating predominantly in the Global South, informal workers manage significant amounts of e-waste, handing nearly 18 billion kg of e-waste in 2022. Current CE research often overlooks their impacts and fails to fully address the social implications of circularity. This gap prompts investigation in aligning CE principles with broader sustainability goals, especially regarding the role of the informal sector in the transition to CE. Formalization emerges as a potential strategy, involving regulation, collaboration, and capacity building to improve resource recovery, livelihoods, and mitigate associated risks while defining the role of the informal sector in circular e-waste management. A comprehensive literature review with seven semi-structured interviews were utilized to explore the formalization of the informal e-waste sector in the context of the global transition to circularity. The main findings reveal that formalization in e-waste management is a complex, multifaceted process requiring legal frameworks, regulatory enforcement, and integration strategies like capacity building and partnerships. The study underscores the importance of integrating informal workers into regulatory frameworks and CE policies to improve resource recovery, reduce environmental impacts, and enhance socio-economic outcomes. The study finds that including informal workers' perspectives may work to enhance effectiveness and adoption of formalization initiatives as part of a just transition to circularity in the EEE value chain and e-waste management.

description: A significant portion of recent Hegel scholarship has taken a primarily historical view on Hegel’s time-sense. Any primarily historical interpretation of Hegelian time, however, ignores the fundamental role immediacy (or the ‘eternal now’) plays in the text’s denouement: the reconciliation between Spirit and the Absolute Other. While the Hegelian time-sense does have a historical aspect – and this can be seen through Hegel’s development of Spirit – the ultimate reconciliation between knower and known must take place now if it is to truly have meaning and relevance now. Leading up to Absolute Knowing, each chapter of the Phenomenology contains at least one instance of temporal immediacy; these instances largely consist of repeated attempts at reconciliation between the knower and the known, instances which, up to Absolute Knowing, come up short for one reason or another. In Absolute Knowing itself, in order for this step to be successful, this reconciliation must be centred in the now, and not in the past.
A Class of Time-Energy Uncertainty Relations for Time-dependent Hamiltonians

description: A new class of time-energy uncertainty relations is directly derived from the Schrödinger equations for time-dependent Hamiltonians. Only the initial states and the Hamiltonians, but neither the instantaneous eigenstates nor the full time-dependent wave functions, which would demand a full solution for a time-dependent Hamiltonian, are required for our time-energy relations. Explicit results are then presented for particular subcases of interest for time-independent Hamiltonians and also for time-varying Hamiltonians employed in adiabatic quantum computation. Some estimates of the lower bounds on computational time are given for general adiabatic quantum algorithms, with Grover's search as an illustration. We particularly emphasise the role of required energy resources, besides the space and time complexity, for the physical process of (quantum) computation in general.

description: Boundaries strongly affect the behavior of quantized vortices in Bose-Einstein condensates, a phenomenon particularly evident in elongated cigar-shaped traps where vortices tend to orient along a short direction to minimize energy. Remarkably, contributions to the angular momentum of these vortices are tightly confined to the region surrounding the core, in stark contrast to untrapped condensates where all atoms contribute $\hbar$. We develop a theoretical model and use this, in combination with numerical simulations, to show that such localized vortices precess in an analogous manner to that of a classical spinning top. We experimentally verify this spinning-top behavior with our real-time imaging technique that allows for the tracking of position and orientation of vortices as they dynamically evolve. Finally, we perform an in-depth numerical investigation of our real-time expansion and imaging method, with the aim of guiding future experimental implementation, as well as outlining directions for its improvement.

description: El uso intensivo de agroquímicos en la agricultura tiene un grave impacto en la salud de los seres humanos y del ambiente; al causar deterioro de los suelos, favorecer la propagación de enfermedades agrícolas, aumentar contaminación (cultivos, aguas y suelos), y estar asociado con el 70% de las pérdidas de especies vegetales. Por lo anterior, es necesario buscar nuevas alternativas, como productos a base de sustancias naturales que sean más accesibles, no generen riesgo para los organismos y puedan ser degradados más fácilmente. Un ejemplo de este tipo de sustancias son las especies del género Piper, que han demostrado propiedades antifúngicas, y por lo tanto podrían ser empleadas en el sector agrícola. Sin embargo, es necesario la implementación de ensayos ecotoxicológicos que demuestran la baja toxicidad de estos extractos para poder ser utilizados. Este proyecto tuvo como objetivo evaluar el efecto de cuatro extractos etanólicos del género Piper (P. peltatum (hojas y tallos), P. eriopodon, y P. pesaresanum) en la germinación y crecimiento de lechuga, tomate y cacao; así como establecer la relación de estos resultados con el contenido de fenoles y flavonoides. En este estudio, se realizaron bioensayos ecotoxicológicos a cuatro extractos etanolicos de Piper a 1000 ppm y 500 ppm, para observar su efecto sobre la germinación y crecimiento de raíces, tallos y brotes de lechuga, tomate y cacao. Adicionalmente, se llevó a cabo la cuantificación de fenoles y flavonoides de los extractos por los métodos de Folin-Ciocalteu y de tricloruro de aluminio. Se encontró que los cuatro extractos a 500 ppm no tuvieron un efecto significativo en la germinación. Sin embargo, los cuatro extractos a 1000 ppm inhibieron la germinación y el crecimiento de las plántulas. Los extractos de P. eriopodon y P. peltatum fueron los que presentaron mayor contenido de fenoles con valores de 251 y 152 mg AG/g extracto, respectivamente, y P. peltatum presentó los mayores valores de flavonoides con valores de 66 y 76 mg QE/g para los extractos de tallos y hojas, respectivamente. Para las tres especies, el extracto de P. eriopodon a 500 ppm destacó por su presentar el menor efecto tóxico en el crecimiento en raíz, tallos y brotes. Así mismo, se determinó que el efecto ecotoxicológico de los extractos puede estar relacionado con el contenido de fenoles y flavonoides presentes en estos, sin embargo, los resultados sugieren que otros factores pudieron influir. Es posible proponer el extracto de P. eriopodon a 500 ppm como posible objetivo de estudio y postularlo como futuro principio activo para la realización de un bioproducto, debido a su bajo nivel tóxico frente a las tres especies evaluadas.

description: In a multidimensional Kaluza-Klein model with Ricci-flat internal space, we study the gravitational field in the weak-field limit. This field is created by two coupled sources. First, this is a point-like massive body which has a dust-like equation of state in the external space and an arbitrary parameter $Ω$ of equation of state in the internal space. The second source is a static spherically symmetric massive scalar field centered at the origin where the point-like massive body is. The found perturbed metric coefficients are used to calculate the parameterized post-Newtonian (PPN) parameter $γ$. We define under which conditions $γ$ can be very close to unity in accordance with the relativistic gravitational tests in the Solar system. This can take place for both massive or massless scalar fields. For example, to have $γ\approx 1$ in the Solar system, the mass of scalar field should be $μ\gtrsim 5.05\times 10^{-49}$g $\sim 2.83\times 10^{-16}$eV. In all cases, we arrive at the same conclusion that to be in agreement with the relativistic gravitational tests, the gravitating mass should have tension: $Ω=-1/2$.

Soil Deal for Europe

description: The main objective of NATI00NS is to facilitate the deployment of the EU Soil Mission across EU Member States and Associated Countries regions, acting as a messenger of the Mission by raising awareness among national and regional stakeholders, providing access to quality-checked capacity-building materials and information, spurring the discussions on the best LL setups to address regional soil needs, and fostering early matchmaking for cross-regional LL clusters. This is done through two rounds of National Engagement Events, envisioned to take place in the first half of 2023 and the first half of 2024, accompanying the EC calls for proposals dedicated to the EU Soil Mission. The present deliverable provides guidelines and tips on the organisation of these events for the benefit of the NATI00NS consortium, and of the organisers of the different national engagement events.

description: जापानी बटेर एक छोटा, प्रवासी, गैलिनियस, जमीन पर रहने वाला खेल पक्षी है जो तीतर परिवार से संबंधित है। उन्हें पहली बार 1595 में जापान में पालतू बनाया गया था। भारत में बटेर की दो प्रजातियां हैं; काली छाती वाली बटेर जंगल में पाई जाती है (कॉटर्निक्स कोरोमैंडेलिका) और भूरे रंग की जापानी बटेर (कॉटर्निक्स कॉटर्निक्स जैपोनिका)। वर्ष 1974 के दौरान, सेंट्रल एवियन रिसर्च इंस्टीट्यूट ने भारत में विविधीकरण के लिए डेविस, कैलिफोर्निया से जापानी बटेर का आयात किया। तब से अनुसंधान के माध्यम से उनके आर्थिक लक्षणों और पशुपालन प्रथाओं में बहुत सुधार हुआ है। भारत में वाणिज्यिक बटेर का पालन अच्छी आय और रोजगार के अवसर का एक बड़ा स्रोत हो सकता है। आर्थिक महत्व के साथ-साथ बटेर की खेती भी बहुत आनंददायक और मनोरंजक है। बटेर बहुत छोटे आकार के कुक्कुट पक्षी होते हैं और उनकी पालन-पोषण प्रणाली बहुत आसान और सरल होती है। बटेर मांस और अंडे दोनों के व्यावसायिक उत्पादन के लिए बहुत उपयुक्त हैं। बटेर लगभग सभी प्रकार की जलवायु और पर्यावरण के साथ खुद को अपना सकते हैं और भारतीय जलवायु व्यावसायिक रूप से बटेर पालने के लिए बहुत उपयुक्त है। वर्तमान में बटेर देश में मुर्गियों और बत्तखों के बाद संख्या में तीसरी सबसे बड़ी एवियन प्रजाति बन गए हैं।
Galactic Shapiro Delay to the Crab Pulsar and limit on Einstein's Equivalence Principle Violation

description: We calculate the total galactic Shapiro delay to the Crab pulsar by including the contributions from the dark matter as well as baryonic matter along the line of sight. The total delay due to dark matter potential is about 3.4 days. For baryonic matter, we included the contributions from both the bulge and the disk, which are approximately 0.12 and 0.32 days respectively. The total delay from all the matter distribution is therefore 3.84 days. We also calculate the limit on violations of Einstein's equivalence principle by using observations of "nano-shot" giant pulses from the Crab pulsar with time-delay $<0.4$~ns as well as using time differences between radio and optical photons observed from this pulsar. Using the former, we obtain a limit on violation of Einstein's equivalence principle in terms of the PPN parameter $Δγ< 2.41\times 10^{-15}$. From the time-difference between simultaneous optical and radio observations, we get $Δγ< 1.54\times 10^{-9}$. We also point out differences in our calculation of Shapiro delay and that from two recent papers (arXiv:1612.00717 and arXiv:1608.07657), which used the same observations to obtain a corresponding limit on $Δγ$.

Reversal of Centrosome Amplification to Reduce Oncogenicity of Metastatic Uveal Melanoma
Creators: name: Fabian-Kolpanowicz, Kim
Publisher: name: Lancaster University
Year: 2023

description: Centrosome amplification (CA), whereby cells have more than the normal number of centrosomes, is a common feature amongst aggressive cancers with a poor prognosis. CA drives oncogenic phenotypes such as increased invasiveness (via both cell-autonomous and non-cell-autonomous mechanisms) and chromosomal instability. In addition, CA can initiate tumourigenesis in flies and mice, and can drive advanced tumourigenic traits early on that promote disease progression. We hypothesise that reversal of CA may reverse CA-driven oncogenic phenotypes and therefore might be a new way to target aggressive cancers with a poor prognosis. This thesis presents the use of three patient-matched uveal melanoma (UM) cell lines as a new model to study CA that has developed in a patient setting. Mel270 cells were derived from a primary tumour and have negligible CA. OMM2.3 and OMM2.5 cells were derived from distinct liver metastases from the same patient and have high levels of CA. Primary UM can be well managed, however ~50% patients develop metastatic disease, for which there is no curative treatment and 1 year survival rates are ~50%, so there is a need to develop new therapies to target metastatic UM. Using RNA-Seq, genes that were differentially expressed in metastasis versus primary derived cells were selected for an siRNA screen to identify genes with a role in CA. Knockdown of either Aurora A or HSP90B1 induced a consistent reduction of CA in OMM2.3 cells. It is believed that Aurora A and HSP090B1 have independent effects on CA, as depleting either Aurora A or HSP90B1 using siRNAs did not affect the RNA or protein levels of the other. A new assay combining live imaging of migrating cells and immunofluorescence was developed and used, which we call FUCCI-CLIF (Fluorescent Ubiquitination based Cell Cycle Indicator - Correlative Live imaging and Immunofluorescence). FUCCI-CLIF provides insight into cell migration, cell cycle and CA status. Knockdown of Aurora A or HSP90B1 reduced migration as calculated by mean straight line speed. Further investigation indicated this was a non-cell-autonomous effect on cell migration. Ultimately, the work presented suggests that depleting or inhibiting proteins required for CA in a cancer specific setting reverses CA and concomitantly reduces oncogenic properties of aggressive metastatic UM cells, and is therefore a much needed new potential therapeutic approach against metastatic UM.
Polarized Sunyaev Zel'dovich tomography

description: Secondary CMB polarization is induced by the late-time scattering of CMB photons by free electrons on our past light cone. This polarized Sunyaev Zel'dovich (pSZ) effect is sensitive to the electrons' locally observed CMB quadrupole, which is sourced primarily by long wavelength inhomogeneities. By combining the remote quadrupoles measured by free electrons throughout the Universe after reionization, the pSZ effect allows us to obtain additional information about large scale modes beyond what can be learned from our own last scattering surface. Here we determine the power of pSZ tomography, in which the pSZ effect is cross-correlated with the density field binned at several redshifts, to provide information about the long wavelength Universe. The signal we explore here is a power asymmetry in the cross-correlation between $E$ or $B$ mode CMB polarization and the density field. We compare this to the cosmic variance limited noise: the random chance to get a power asymmetry in the absence of a large scale quadrupole field. By computing the necessary transfer functions and cross-correlations, we compute the signal-to-noise ratio attainable by idealized next generation CMB experiments and galaxy surveys. We find that a signal-to-noise ratio of $\sim 1-10$ is in principle attainable over a significant range of power multipoles, with the strongest signal coming from the first multipoles in the lowest redshift bins. These results prompt further assessment of realistically measuring the pSZ signal and the potential impact for constraining cosmology on large scales.

description: Cardiovascular disease, also known as CVD, is the most common cause of mortality worldwide. The heart's arteries, blood vessels, and heart muscles become susceptible in the majority of CVD cases. The study focuses on the role which hypertension, as well as varying dense triglyceride and cholesterol levels, play in the onset and progression of cardiovascular disease. This review includes covers potential biomarkers such as homocysteine, fibrinogen, plex, the cytokines, and serum amyloid, along with the prognostic effects of thrombin/anti-thrombin III.
