PyCFTBoot: A flexible interface for the conformal bootstrap
Creators: name: Behan, Connor
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We introduce PyCFTBoot, a wrapper designed to reduce the barrier to entry in conformal bootstrap calculations that require semidefinite programming. Symengine and SDPB are used for the most intensive symbolic and numerical steps respectively. After reviewing the built-in algorithms for conformal blocks, we explain how to use the code through a number of examples that verify past results. As an application, we show that the multi-correlator bootstrap still appears to single out the Wilson-Fisher fixed points as special theories in dimensions between 3 and 4 despite the recent proof that they violate unitarity.

description: 1057 globular cluster candidates have been identified in a WFPC2 image of the inner region of M87. The Globular Cluster Luminosity Function (GCLF) can be well fit by a Gaussian profile with a mean value of m_V^0=23.67 +/- 0.07 mag and sigma=1.39 +/- 0.06 mag (compared to m_V^0=23.74 mag and sigma=1.44 mag from an earlier study using the same data by Whitmore it et al. 1995). The GCLF in five radial bins is found to be statistically the same at all points, showing no clear evidence of dynamical destruction processes based on the luminosity function (LF), in contradiction to the claim by Gnedin (1997). Similarly, there is no obvious correlation between the half light radius of the clusters and the galactocentric distance. The core radius of the globular cluster density distribution is R_c=56'', considerably larger than the core of the stellar component (R_c=6.8''). The mean color of the cluster candidates is V-I=1.09 mag which corresponds to an average metallicity of Fe/H = -0.74 dex. The color distribution is bimodal everywhere, with a blue peak at V-I=0.95 mag and a red peak at V-I=1.20 mag. The red population is only 0.1 magnitude bluer than the underlying galaxy, indicating that these clusters formed late in the metal enrichment history of the galaxy and were possibly created in a burst of star/cluster formation 3-6 Gyr after the blue population. We also find that both the red and the blue cluster distributions have a more elliptical shape (Hubble type E3.5) than the nearly spherical galaxy. The average half light radius of the clusters is ~2.5 pc which is comparable to the 3 pc average effective radius of the Milky Way clusters, though the red candidates are ~20% smaller than the blue ones.

Conformal symmetry wormholes and the null energy condition
Creators: name: Kuhfittig, Peter K. F.
Publisher: name: arXiv
Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper we seek a relationship between the assumption of conformal symmetry and the exotic matter needed to hold a wormhole open. By starting with a Morris-Thorne wormhole having a constant energy density, it is shown that the conformal factor provides the extra degree of freedom sufficient to account for the exotic matter. The same holds for Morris-Thorne wormholes in a noncommutative-geometry setting. Applied to thin shells, there would exist a radius that results in a wormhole with positive surface density and negative surface pressure and which violates the null energy condition on the thin shell.

The economics of crowding in urban rail transport
Creators: name: Hörcher, Daniel
Publisher: name: Imperial College London
Year: 2017

description: Crowding is a major source of inconvenience for public transport users in densely populated metropolitan areas globally, while eliminating crowding requires costly investments. Crowding can be considered as a cornerstone phenomenon of public transport theory, as the interaction between demand and supply side policies. This PhD thesis aims to improve our understanding of the mechanics behind crowding, using microeconomic modelling techniques. From a demand perspective, the crucial precondition of any objective economic analysis is to reliably quantify the inconvenience caused by crowding. In pursuit of this goal, the thesis develops a statistical model to infer the user cost of crowding from metro passengers' route choice decisions. As an important intermediate research outcome, the thesis delivers a novel passenger-to-train assignment algorithm that recovers the network-level crowding pattern of a metro system. Our method is a unique contribution in the sense that it is based on large-scale automated datasets: we use smart card and automated vehicle location data only. The theoretical part of the thesis provides new insights into crowding pricing and capacity optimisation. One of the key messages of the thesis is that crowding in certain time periods and network segments is an unavoidable feature of optimal public transport provision, when demand fluctuates by time and space, but capacity cannot be differentiated between jointly served markets. We show that pricing can be an efficient tool to tackle the deficiency caused by this technological constraint. The thesis devotes special attention to two policy relevant applications: (i) the external cost of seat occupancy, an externality inversely proportional to the density of crowding, and (ii) the inefficiency of unlimited-use travel passes. Our conclusions may assist researchers and practitioners in better understanding the true cost of public transport usage and the related aspects of optimal policy design, including pricing, subsidisation and capacity provision.

Magnetic monopole creation
Creators: name: Gould, Oliver
Publisher: name: Imperial College London
Year: 2017

description: Elementary magnetic monopoles have never been experimentally observed but there are credible theoretical reasons to believe that they may nonetheless exist. This thesis gives partial answers to the questions: if magnetic monopoles do exist, can we create them? And if so, how? Surprisingly little is known about the answers to these simple-sounding questions. The fundamental stumbling block is the strong coupling of magnetic monopoles. This prevents the usual arsenal of techniques from being used, which have proved so useful in understanding the creation of everything from electrons to Higgs particles to quarks. I consider magnetic monopole creation in strong magnetic fields and at high temperatures. I show that the semiclassical approximation is valid, despite the strong coupling, and calculate the rate using the worldline formalism. The leading order results suggest that magnetic monopoles will be created amply above a certain threshold magnetic field strength and temperature. This is independent of many details of the particles, in particular their spin and whether they are elementary or composite. Strong magnetic fields and high temperatures are present in neutron stars and in terrestrial heavy ion collisions. By comparison with known properties of neutron stars, and with a search for magnetic monopoles at CERN, I derive the strongest yet, model-independent bounds on the mass of any possible magnetic monopoles. However, investigating higher order corrections to my results, I encounter an instability in the equations which casts doubt on the validity of my approximations and hence the mass bounds. In answer to my questions: if magnetic monopoles do exist, we may be able to create them in sufficiently high energy heavy ion collisions. However, more theoretical work is needed to decide upon this, both to overcome the issue of the instability and to understand the effects of the spacetime evolution of such collisions.

description: The laws of thermodynamics require any initial macroscopic inhomogeneity in extended many-body systems to be smoothed out by the time evolution through the activation of transport processes. In generic, non-integrable quantum systems, transport is expected to be governed by a diffusion law, whereas a sufficiently strong quenched disorder can suppress it completely due to many-body localization of quantum excitations. Here we show that the confinement of quasi-particles can also lead to transport suppression even if the dynamics are generated by homogeneous Hamiltonians. We demonstrate this in the quantum Ising chain with transverse and longitudinal magnetic fields in the paradigmatic case of the evolution of domain-wall states. We perform extensive numerical simulations of the dynamics which turn out to be in excellent agreement with an effective analytical description valid within both weak and strong confinement regimes. Our results show that the energy flow from "hot" to "cold" regions of the chain is suppressed for all accessible times. We argue that this phenomenon is connected with the presence of atypical states in the many-body energy spectrum which violate the eigenstate thermalization hypothesis, as recently reported in the literature.

Dynamic subsidence, continental uplift and sedimentary deposition to West Africa’s passive margin
Creators: name: Lodhia, Bhavik Harish
Publisher: name: Imperial College London
Year: 2018

description: The relationship between offshore subsidence, continental uplift and sedimentary deposition to passive margins is poorly understood. A history of dynamic subsidence, continental uplift and sedimentary deposition to West Africa’s passive margin was synthesised to produce a framework for predicting patterns of sedimentary flux to the Mauritanian basin. Stratigraphy was mapped using seismic/well data and Cretaceous–Recent sedimentary flux was calculated. Clastic sedimentary flux to the centre of the basin increased significantly during Neogene times and accelerated across the basin at ~ 5 Ma. The origins of the Mauritanian basin were explored by backstripping wells from the study area to calculate subsidence histories. Seismic, well, gravity, magmatic and tomographic information was used to show that < 0:8 km of rapid Neogene– Recent subsidence occurred due to the initiation of shallow mantle convection. Neogene–Recent mantle draw-down caused the creation of accommodation within the Mauritanian basin that was subsequently filled by clastic sediments delivered by rivers draining West Africa’s passive margin. The causes of increased Neogene–Recent sedimentary flux were explored by inverting 14700 African longitudinal river profiles using a calibrated stream–power model to calculate a history of continental uplift and to predict the pattern of sedimentary flux to the Mauritanian basin. Results are consistent with independent stratigraphic observations which indicate that from ~ 30 Ma–Recent, sedimentary flux to Africa’s major deltas increased and induced a change from dominantly carbonate to clastic deposition. This pattern of sedimentary flux is consistent with calculations of offshore sedimentary volumes made using seismic and well data. I suggest Neogene clastic flux to the Mauritanian margin was generated by denudation of the uplifting Fouta-Djallon topographic swell and Mauritinides fold-belt, which appears to have accelerated during the last ~ 5 Ma. Results suggest that mantle-driven convective continental uplift exerts an important control on the sedimentary budget to Africa’s passive margins.

description: The shape of the primordial fluctuation spectrum is probed by cosmic microwave background fluctuations which measure density fluctuations at z~1000 on scales of hundreds of Mpc and from galaxy redshift surveys, which measure structure at low redshift out to several hundred Mpc. The currently acceptable library of cosmological models is inadequate to account for the current data, and more exotic models must be sought. New data sets such as SDSS and 2DF are urgently needed to verify whether the shape discrepancies in P(k) will persist.

description: The notion of commutativity of two normal states on a von Neumann algebra was defined some time ago by means of the Pedersen-Takesaki theorem. In this note we aim at generalizing this notion to an arbitrary number of states, and obtaining some results on so defined joint commutativity. Also relations between commutativity and broadcastability of states are investigated.

Publisher: name: Zenodo
Year: 2024

description: This paper studies the financial cooperation between China and Turkmenistan in the context of the "the Belt and Road" through quantitative analysis. First, the development status of financial cooperation between China and Turkmenistan in the context of the "the Belt and Road" is described through three parts: the current situation of macroeconomic development between China and Turkmenistan, the current situation of import and export trade in financial services, and the current situation of financial cooperation; Then, the analysis of the influencing factors on the development of financial cooperation between China and Turkmenistan is elaborated through three parts: indicator selection and data sources, empirical testing, and empirical analysis. The empirical analysis results show that the per capital financial wealth of Turkmenistan and the total financial wealth of Turkmenistan have a promoting effect on financial cooperation between China and Turkmenistan, while the per capital financial wealth of China has a relatively small impact on financial cooperation between China and Turkmenistan; The explanation of financial cooperation in China and Turkmenistan ranges from large to small: per capital financial wealth in Turkmenistan, financial cooperation in China and Turkmenistan, total financial wealth in Turkmenistan, and per capital financial wealth in China. Finally, this article proposes some policy suggestions: to improve the development of Turkmenistan's financial industry and promote the increase of total wealth; Improving the per capital financial wealth of Turkmenistan and focusing on per capital income development; Optimize the allocation ratio of investment financial assets in China and promote the growth of per capital financial wealth in China.

description: The recent Cherenkov telescope observations and detections of the BL Lac objects Mkn 421, Mkn 501, 1ES 2344+514, PKS 2155--304 and possibly 1ES 1959+658 have shown that there exists a subclass of BL Lac objects emitting a substantial fraction of their power between the GeV and the TeV bands. These are the sources whose synchrotron spectrum peaks, in a $ν$--$νF_ν$ representation, in the EUV or X-ray band. Here I suggest that even more extreme BL Lacs can exist, whose synchrotron spectrum peaks in the MeV band. These sources should emit a substantial fraction of their power in the TeV band by the inverse Compton process. Limits to the maximum possible emitted frequencies are discussed.

Normality and Gap Phenomena in Optimal Unbounded Control

description: Optimal unbounded control problems with affine control dependence may fail to have minimizers in the class of absolutely continuous state trajectories. For this reason, extended impulsive versions --which cannot be of measure-theoretical type-- have been investigated, in which the domain is enlarged to include discontinuous state trajectories of bounded variation, and for which existence of minimizers is guaranteed. It is of interest to know whether the passage from the original optimal control problem to its extension introduces an infimum gap. This paper provides sufficient conditions for the absence of an infimum gap based on normality of extremals. In certain cases, the normality conditions reduce to simple verifiable criteria, which improve on earlier, directly-derived sufficient conditions for no infimum gap.
Advanced computational modelling of large-scale tidal energy systems: optimising the trade-off between environmental impacts and power generation
Creators: name: Du Feu, Roan
Publisher: name: Imperial College London
Year: 2018

description: The future of the UK tidal industry is uncertain. The usefulness of tidal power is not in question, but, as a relatively untested energy source, its practicality and impacts are. In this thesis, the environmental impacts of tidal development are contrasted with the potential to produce power and profit. Initially, the interaction between power generation and alteration of the current is posed as a multi-objective optimisation problem. A methodology is presented to effectively optimise array formation for conflicting societal objectives. In the test cases presented, areas around a tidal array can at times be protected from change at minimal cost to an array’s power generation capacity. Habitat suitability modelling is then incorporated into the array design process and, by selecting two species sensitive to changes in the flow, both positive and negative interactions with tidal development are evaluated. Using the Pentland Firth as a test case, the trade-offs between profit generation and habitat extent of the chosen species are determined, and a Pareto set of optimal array designs is found. A coastal model of the whole UK is then produced, and all prospective areas of tidal development are identified. This ’maximum development’ tidal scenario aligns with the Crown Estate’s estimate of the UK’s theoretical resource. Large changes in the flow regime are seen within 10 km of farms, while small changes are seen up to 120 km away. The impact of these changes on UK marine habitat is assessed for a set of six habitat indicator species. The impact is generally low, but, in the vicinity of the farms themselves, up to 8 % of habitat is affected. Finally, aspects of the Ocean Health Index, a global measure of ocean health, are used to compare the profit- generating potential of the tidal industry with its potential impact on habitat. Under this measure, all impacts on ocean health are small, and, importantly, the overall impact is positive.
OEDIPUS: An Experiment Design Framework for Sparsity-Constrained MRI

description: This paper introduces a new estimation-theoretic framework for experiment design in the context of MR image reconstruction under sparsity constraints. The new framework is called OEDIPUS (Oracle-based Experiment Design for Imaging Parsimoniously Under Sparsity constraints), and is based on combining the constrained Cramér-Rao bound with classical experiment design techniques. Compared to popular random sampling approaches, OEDIPUS is fully deterministic and automatically tailors the sampling pattern to the specific imaging context of interest (i.e., accounting for coil geometry, anatomy, image contrast, etc.). OEDIPUS-based experiment designs are evaluated using retrospectively subsampled in vivo MRI data in several different contexts. Results demonstrate that OEDIPUS-based experiment designs have some desirable characteristics relative to conventional MRI sampling approaches.

A critique of scaling behaviour in non-linear structure formation scenarios
Creators: name: Kanekar, Nissim
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Moments of the BBGKY equations for spatial correlation functions of cosmological density perturbations are used to obtain a differential equation for the evolution of the dimensionless function, $h = - ({v/{\dot{a}x}})$, where $v$ is the mean relative pair velocity. The BBGKY equations are closed using a hierarchical scaling ansatz for the 3-point correlation function. Scale-invariant solutions derived earlier by Davis and Peebles are then used in the non-linear regime, along with the generalised stable clustering hypothesis ($h \to $ const.), to obtain an expression for the asymptotic value of $h$, in terms of the power law index of clustering, $γ$,and the tangential and radial velocity dispersions. The Davis-Peebles solution is found to require that tangential dispersions are larger than radial ones, in the non-linear regime; this can be understood on physical grounds. Finally, stability analysis of the solution demonstrates that the allowed asymptotic values of $h$, consistent with the stable clustering hypothesis, lie in the range $0 \leq h \leq 1/2$. Thus, if the Davis-Peebles scale-invariant solution (and the hierarchical model for the 3-pt function) is correct, the standard stable clustering picture ($h \to 1$ as $\barξ\to \infty$) is not allowed in the non-linear regime of structure formation.

SLAM and deep learning for 3D indoor scene understanding
Creators: name: McCormac, Brendan John
Publisher: name: Imperial College London
Year: 2018

description: We build upon research in the fields of Simultaneous Localisation and Mapping (SLAM) and Deep Learning to develop 3D maps of indoor scenes that not only describe where things are but what they are. We focus on real-time online methods suitable for applications such as domestic robotics and augmented reality. While early approaches to SLAM used sparse feature maps for localisation, recent years have seen the advent of real-time dense SLAM systems which enabled applications not possible with only sparse feature maps. Further augmenting dense maps with semantic information will in future enable more intelligent domestic robots and more intuitive human-map interactions not possible with map geometry alone. Early work presented here sought to combine recent advances in semantic segmentation using Convolutional Neural Networks (CNNs) with dense SLAM approaches to produce a semantically annotated dense 3D map. Although we found this combination improved segmentation performance, its inherent limitations subsequently led to a paradigm shift away from semantic annotation towards instance detection and 3D object-level mapping. We propose a new type of SLAM system consisting of discovered object instances that are reconstructed online in individual volumes. We develop a new approach to robustly combine multiple associated 2D instance mask detections into a fused 3D foreground segmentation for each object. The use of individual volumes allows the relative poses of objects to be optimised in a pose-graph, producing a consistent global map that allows objects to be reused on loopy trajectories, and which can improve reconstruction quality. A notable feature of CNNs is their ability to make use of large annotated datasets, and so we also explore methods to reduce the cost of indoor semantic dataset production. We explore SLAM as a means of mitigating labour intensive annotation of video data, but found that producing a large-scale dataset with such an approach would still require significant resources. We therefore explore automated methods to produce a large-scale photorealistic synthetic dataset of indoor trajectories at low cost, and we verify the benefits of the dataset on the task of semantic segmentation. To automate trajectory generation we present a novel two-body random trajectory method that mitigates issues of a completely random approach, and which has subsequently been used in other synthetic indoor datasets.

description: A substantial population of high redshift early-type galaxies is detected in very deep UBVRIJHK images towards the HDF-South. Four elliptical profile galaxies are identified in the redshift range z=1-2, all with very red SEDs, implying ages of >2 Gyrs for standard passive evolution. We also find later type IR-luminous galaxies at similarly high redshift, (10 objects with z>1, H<25), whose weak UV emission implies single burst ages of >1 Gyr. The number and luminosity-densities of these galaxies are comparable with the local E/SO-Sbc populations for Ω_m>0.2, and in the absence of a significant cosmological constant, we infer that the major fraction of luminous Hubble-sequence galaxies have evolved little since z~2. A highly complete photometric redshift distribution is constructed to H=25 (69 galaxies) showing a broad spread of redshift, peaking at z~1.5, in reasonable agreement with some analyses of the HDF. Five `dropout' galaxies are detected at z~3.8, which are compact in the IR, ~0.5 kpc/h at rest 3500Å. No example of a blue IR luminous elliptical is found, restricting the star-formation epoch of ellipticals to z>10 for a standard IMF and modest extinction.

Modelling ISO Galaxy Counts with Luminosity and Merger Rate Evolution

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We model galaxy evolution in the 6.75 and 15 micron passbands of the ISO satellite, by combining models of galaxy evolution at optical wavelengths (which are consistent with the optical galaxy counts) with observed spectral energy distributions in the infra-red. Our model is consistent with the local 12 micron galaxy luminosity, if 3.5 per cent of spirals at z=0 are in interacting pairs with mid-infra-red luminosities enhanced by major starbursts. Source counts from deep ISO surveys exceed non-evolving predictions but are more consistent with our evolving model. The steep number count of 6.75 micron sources appears to be explained primarily by evolving early-type galaxies, whereas at 15 microns the main contributors are star-forming spirals and starbursting interacting/merging galaxies. The 31 per cent of 15 micron sources which are visibly interacting galaxies have high mid-infra-red/optical flux ratios indicating major starbursts combined with dust extinction. The numbers and high mean redshift of these sources suggest the merger-starbursts are increasing in luminosity with redshift, approximately as (1+z)^2, in addition to undergoing (1+z)^2 number evolution reflecting the optically observed increase with redshift in the fraction of interacting galaxies.

description: The availability of large diachronic corpora has provided the impetus for a growing body of quantitative research on language evolution and meaning change. The central quantities in this research are token frequencies of linguistic elements in texts, with changes in frequency taken to reflect the popularity or selective fitness of an element. However, corpus frequencies may change for a wide variety of reasons, including purely random sampling effects, or because corpora are composed of contemporary media and fiction texts within which the underlying topics ebb and flow with cultural and socio-political trends. In this work, we introduce a simple model for controlling for topical fluctuations in corpora - the topical-cultural advection model - and demonstrate how it provides a robust baseline of variability in word frequency changes over time. We validate the model on a diachronic corpus spanning two centuries, and a carefully-controlled artificial language change scenario, and then use it to correct for topical fluctuations in historical time series. Finally, we use the model to show that the emergence of new words typically corresponds with the rise of a trending topic. This suggests that some lexical innovations occur due to growing communicative need in a subspace of the lexicon, and that the topical-cultural advection model can be used to quantify this.

Implicit human-robot interfacing in robotic surgery
Creators: name: Gras, Gauthier
Publisher: name: Imperial College London
Year: 2018

description: The surgical environment presents a large number of challenges for surgeons, from the crucial planning and decision-making processes involved, to the technical skills required to complete a surgical task. To tackle these challenges, systems of increasing capabilities have been designed. Surgical robots provide enhanced dexterity under the restrictive conditions of minimally invasive surgery, and advanced imaging and registration modalities allow powerful planning and localisation capabilities for surgery. However, despite the increasing complexity and capability of modern surgical robot systems, human-robot interfaces have remained largely unchanged. Modern surgical robots possess many degrees of freedom and system-specific dexterous workspaces, yet are still mainly controlled using a static motion scaling master-slave scheme in Cartesian space. Likewise, image guidance information displayed on separate displays force interruptions of the surgical workflow when used, as the surgeon needs to take their attention away from the surgical scene. In order to fully utilise the capabilities provided by these systems, improved user-interfaces taking advantage of the context of the surgical scene need to be developed. This thesis explores the design of such human-user interfaces for two main cases: interfaces responsible for the control of robotic systems, and surgical navigation interfaces. A key motivation for this work is to generate methods for robotic control and navigation that feel transparent to the user. These interfaces should act implicitly based on the context of the surgical scene, as opposed to requiring explicit user input. Firstly, an implicit approach to control the surgical camera and a focussed energy delivery system is explored, using gaze information and no active gestures. This approach is then expanded for intention recognition, to dynamically adapt motion scaling of master-slave systems. Bayesian approaches to tune these interfaces are also studied, showing the importance of not relying on manual tuning. The methods previously developed for intention recognition are then expanded and applied to augmented reality, to provide optimal display behaviour in robotic applications. Finally, an approach is developed combining augmented reality and force feedback to provide implicit assistance for hand-held robotic instruments. Throughout this work, results from studies conducted for each of the proposed methods demonstrate the capabilities and potential clinical value of context-aware interfaces to improve performance.
Extending functions from isotropic Nikolskii-Besov spaces and their approximating with derivatives

description: The article examines isotropic Nikolskii and Besov spaces with norms defined using $L_p$-averaged modulus of continuity of functions of appropriate order, instead of modulus of continuity of known order for fixed-order partial derivative functions. The author builds continuous linear mappings of such spaces of functions defined in domains of $(1,\ldots,1)$-type (in a broad sense) to ordinary isotropic Nikolskii and Besov spaces in $ \mathbb R^d $ that are function extension operators, thus incurring coincidence of both kinds of spaces in the said domains. It is established that every bounded domain in $ \mathbb R^d $ with a Lipschitzian boundary is a $(1,\ldots,1)$-type domain (in a broad sense). The article also provides weak asymptotics of approximation characteristics related to the problem of reconstruction of functions with their derivatives from function values at a given number of points, the S.B.Stechkin's problem for differential operator, and the problem of width asymptotics for isotropic Nikolskii-Besov classes in those domains.

The ecology of Raoiella indica (Hirst: Tenuipalpidae) in India and Trinidad: Host plant relations and predator: prey relationships
Creators: name: Taylor, Arabella Bryony Katharine
Publisher: name: Imperial College London
Year: 2017

description: Red Palm Mite, Raoiella indica (Acari:Tenuipalpidae) (RPM), an Old World species first recorded in India (1924), was reported historically on a small number of host species of Arecaceae (palms) throughout Asia and the Middle East. In 2004, the mite invaded the New World resulting in high population densities and apparent new host associations- including Musa spp. (bananas and plantains). Subsequently, RPM has become widely established in the tropical Americas. The aim of the work was to understand some of the factors underlying the differences in RPM population status between the two regions by comparing morphological and molecular characteristics, investigating Old World host relations and comparing predator–prey interactions in India and Trinidad. Field population densities on main host Cocos nucifera were significantly higher in Trinidad compared to India. Substantial RPM field densities and breeding colonies were confirmed on Musa spp. in Trinidad, but not India; although RPM was shown to survive and lay eggs on Musa spp. in vitro in India. Arthropod predator diversity in India was higher on C. nucifera and lower on Musa spp. compared to Trinidad. Surveys on both host species only recorded predatory mites in Trinidad, whereas predatory insects and mites were recorded in India. Although molecular studies were unsuccessful, morphological studies showed that, independent of host plant, RPM had significantly longer lateral setae in the Caribbean compared to India. Adventive range populations may have resulted from a genetic bottleneck upon introduction. Assays in Trinidad showed that RPM with droplets on dorsal setae were contacted and consumed by Amblyseius largoensis on fewer occasions than those without. Setae may also play a role in defence against A. largoensis. Studies confirmed differences in RPM severity and status on host plants between regions and suggest natural enemies play a role in maintaining a narrow host range in India.

description: Actualmente, como consequência da globalização, constata-se uma interpenetração nos vários carizes da realidade, de que o ensino superior não é alheio. De facto, as instituições de ensino superior, de diferentes países, intensificam cada vez mais a cooperação entre si. Verifica-se desta forma, um intensificar da internacionalização do ensino superior e da mobilidade de estudantes, bem como do pessoal académico e não académico. Esta partilha de ideias, culturas, identidades e competências levam também ao empreendedorismo, à inovação e à competitividade entre países. É objectivo deste artigo reflectir não só sobre a temática da internacionalização do ensino superior alemão mas também do empreendedorismo no ensino superior.

description: We use filtered modules over a Noetherian ring and fibred bounded control on homomorphisms to construct a new kind of controlled algebra with applications in geometric topology. The theory here can be thought of as a "pushout" of the bounded K-theory with fibred control and the controlled G-theory constructed and used by the authors. This paper contains the non-equivariant theory including controlled excision theorems crucial for computations.

Microlocal analysis of Doppler Synthetic Aperture Radar

description: We study the existence and suppression of artifacts for a Doppler-based Synthetic Aperture Radar (DSAR) system. The idealized air- or space-borne system transmits a continuous wave at a fixed frequency and a co-located receiver measures the resulting scattered waves; a windowed Fourier transform then converts the raw data into a function of two variables: slow time and frequency. Under simplifying assumptions, we analyze the linearized forward scattering map and the feasibility of inverting it via filtered backprojection, using techniques of microlocal analysis which robustly describe how sharp features in the target appear in the data. For DSAR with a straight flight path, there is, as with conventional SAR, a left-right ambiguity artifact in the DSAR image, which can be avoided via beam forming to the left or right. For a circular flight path, the artifact has a more complicated structure, but filtering out echoes coming from straight ahead or behind the transceiver, as well as those outside a critical range, allows one to obtain an artifact-free image. Initially derived under a start-stop approximation widely used in range-based SAR, we show that some of these results are robust and hold under a more realistic approximation.

description: In a globalized world, where almost everyone possesses a digital device and there’s Internet connection in every corner, social networks appear as people’s favorite web places to navigate and personalize. When social networks become a tool of influence and behavior change, as a result of being an all-time occupation for individuals, they change the operating mode of every organization as well as the way we interact inside our community and with others. The aim of this paper is to analyze how the current importance of social networks and their use influences different cultural areas and the individual in addition to his personal relationships.
