Publisher: name: E- Revista de Estudos Interculturais
Year: 2021

description: O presente artigo discute a partir das poesias de Baudelaire reunidas em Quadros Parisienses do livro As Flores do Mal, a modernidade imposta ao espaço urbano no século XIX. Esta modernização transformou profundamente não só os lugares, mas também as pessoas e as relações entre elas. Neste estudo vamos usar a edição bilíngue – francês/português – de As Flores do Mal. Nossa leitura de Baudelaire se pautará na necessidade apontada por Fredric Jameson (1992) de se "restaurar para a superfície do texto a realidade reprimida e soterrada da (...) história". Vamos, assim, ao encontro do que foi exposto na tese VII de Walter Benjamin, Sobre o conceito da história, em que ele afirma que "nunca houve um documento da cultura que não fosse também um documento da barbárie".

description: Efficient and truthful mechanisms to price resources on remote servers/machines has been the subject of much work in recent years due to the importance of the cloud market. This paper considers revenue maximization in the online stochastic setting with non-preemptive jobs and a unit capacity server. One agent/job arrives at every time step, with parameters drawn from an underlying unknown distribution.
 We design a posted-price mechanism which can be efficiently computed, and is revenue-optimal in expectation and in retrospect, up to additive error. The prices are posted prior to learning the agent's type, and the computed pricing scheme is deterministic, depending only on the length of the allotted time interval and on the earliest time the server is available. If the distribution of agent's type is only learned from observing the jobs that are executed, we prove that a polynomial number of samples is sufficient to obtain a near-optimal truthful pricing strategy.
Optical near-field dynamics of active 2D semiconductors
Creators: name: Guazzotti, Stefano
Publisher: name: Imperial College London
Year: 2018

description: When structures with a strong confinement of the electromagnetic fields are considered, the near-field dynamics becomes integral to the description of a semiconductor. Not only it provides feedback from the environment, as is the case in a laser system, but it further mediates the interaction between different, otherwise independent, positions. In such a context, a full-field spatio-temporal description is essential to faithfully describe the dynamics of either an extended semiconductor system or a set of spatially separated emitters. This thesis highlights the importance of combining a complex (many-body and band-resolved) model of semiconductor carrier dynamics with a full-field description of the electromagnetic fields by presenting some applications. With the recent rise in popularity of atomically thin materials, semiconductors can be embedded in increasingly smaller optical environments, whose properties can only be studied by self-consistently combining carrier and field dynamics. The ability to calculate the linear and non-linear response of a system under arbitrary excitation conditions is shown. This is performed without any prior knowledge of the electromagnetic environment and can thus be extended to complex geometries. By embedding active materials in a tailored environment, the complex interaction of the two can be exploited to engineer the optical response of the system by using a self-consistent modelling technique. The complex dynamical interaction between field and gain in a semiconductor laser is another example of a system in which a self-consistent model is required. Here, a set of one-dimensional simulations is reported showing how the output of a semiconductor laser is highly sensitive to perturbation arising from sub-wavelength dynamics of the gain medium. By introducing a random patterning of the laser cavity, a novel approach to the suppression of dynamical instabilities in a laser output is demonstrated. This scheme, based on complex wave interference, is introduced by spatially perturbing the optical environment.

description: A purely electronic mechanism is proposed for the unconventional superconductivity recently observed in twisted bilayer graphene (tBG) close to the magic angle. Using the Migdal-Eliashberg framework on a one parameter effective lattice model for tBG we show that a superconducting state can be achieved by means of collective electronic modes in tBG. We posit robust features of the theory, including an asymmetrical superconducting dome and the magnitude of the critical temperature that are in agreement with experiments.

description: We investigate the quantum correlation for tripartite entangled states in de Sitter space. First, we adopt the noisy quantum channel model. In this model, the expansion effect is represented by an operator sum representation with its corresponding Kraus operator. This map is shown to be trace-preserving and completely positive. Second, we analyze the quantum correlation by using the channel-state correspondence. For a large expansion rate, the tripartite mutual information has a large negative value, which corresponds to a small magnitude of bipartite mutual information. We relate this result with the challenge of recovering information from local measurements.

description: Infrared Imaging Surveyor (IRIS) is a satellite which will be launched in the beginning of 2003. One of the main purposes of the IRIS mission is an all-sky survey at far-infrared (FIR) with a flux limit much deeper than that of IRAS. In order to examine the performance of the survey, we estimated the FIR galaxy counts in four (50, 70, 120, and 150 $μ$m) bands based on some models. We adopted a multicomponent model which consists of cirrus and starburst components for galaxy spectra, and the nearby FIR luminosity function derived from that of IRAS galaxies. We derived the number counts, redshift distributions, and infrared diffuse background radiation spectra for i) no evolution, ii) pure luminosity evolution, iii) pure density evolution with $q_0 = 0.1$ and 0.5. We found that a large number of galaxies ($\sim {\rm a few} \times 10^6$ in the whole sky) will be detected in this survey. With the aid of a vast number of detection, we will detect the effect of galaxy evolution, and evaluate the amplitude of evolution at least in the nearby universe in the IRIS survey, though it will be still difficult to constrain which type of evolution takes place from the number count alone. We also studied the estimation of redshifts of detected galaxies by their infrared colors alone. Although significant contamination takes place among nearby faint galaxies and high-$z$ ones, we found that rough estimation of galaxy redshift can be practicable by jointly using present and future optical surveys.

Developing and adopting complex health innovations – The case of genetically modified mosquitoes for malaria eradication
Creators: name: Cisnetto, Valentina
Publisher: name: Imperial College London
Year: 2016

description: Background: Malaria, a preventable and curable disease, is still one the primary causes of death worldwide. Around 90% of deaths occur in sub-Saharan Africa. Increased funding and new programmes by international agencies and national governments have led to significant progress in malaria control, but the improvement curve is levelling off. This is due to the limitations of current technologies and difficulties in deploying the interventions on the ground. There are calls for technological innovations which are able to provide interventions that are cost-effective, sustainable, area-wide and equitable. The development of selfsustaining genetically modified (GM) Anopheles mosquitoes is deemed to have these potential attributes, but this technology is not only innovative, but also highly complex and controversial. Using the introduction of GM mosquitoes for malaria eradication in Burkina Faso as an example this study helps to better understand how complex health technology innovations are adopted in low-income countries. Methods: The research uses a mixed methods approach and combines an in-depth analysis of the Burkinabé (Burkina Faso) health system and its wider context, qualitative system dynamics modelling and an econometric analysis in order to investigate the key barriers and enablers that influence the adoption of GM mosquito technology. Results: The research confirms the importance of community trust and acceptance, and health system readiness, in influencing the adoption process. It also emphasises the need for a perspective on the adoption of highly complex innovations which takes more account of the iterative nature of their development, the interrelationship between development and adoption, and the cognitive barriers in stakeholders’ understanding of the technology. Conclusions: The intrinsic complexity of the technology development and local adoption processes, and the fact that the nature of the technology itself means that adoption decisions are societal rather than individual, together have important implications for policy and practice. These need to be taken into consideration both by local policy makers and technology researchers.

description: The recent experimental observations of decaying energy oscillations in semiconductor-superconductor Majorana nanowires is in contrast with the typical expectations based on the presence of Majorana zero modes localized at the ends of the system, when the amplitude of the hybridization energy oscillations is predicted to increase with the applied magnetic field. These observations have been theoretically justified recently by considering a position-dependent, step-like spin-orbit coupling near end of the nanowire, which could arise due to the presence of tunnel gates in a standard tunneling conductance experiment. Here, we show that the window in parameter space where this phenomenology occurs is vanishingly small, when compared to the parameter region where Majorana oscillations increase in amplitude with the applied field. Further, including a position-dependent effective potential, which is also induced naturally near the end of the wire by, e.g., tunnel gates, practically removes the small window associated with decaying oscillations. Using extensive numerical calculations, we show that, as expected, increasing amplitude oscillations of the hybridization energy represent a generic property of topological Majorana zero modes, while decreasing amplitude oscillations are a generic property of low-energy trivial Andreev bound states that typically emerge in non-homogeneous systems. By averaging over several realistic parameter configurations, we identify robust features of the hybridization energy that can be observed in a typical differential conductance experiment without fine-tuning the control parameters.

description: Cavity-polaritons in semiconductor microstructures have emerged as a promising system for exploring nonequilibrium dynamics of many-body systems. Key advances in this field, including the observation of polariton condensation, superfluidity, realization of topological photonic bands, and dissipative phase transitions, generically allow for a description based on a mean-field Gross-Pitaevskii formalism. While observation of polariton intensity squeezing and decoherence of a polarization entangled photon pair by a polariton condensate provide counter-examples, quantum effects in these experiments show up at high polariton occupancy. Going beyond into the regime of strongly correlated polaritons requires the observation of a photon blockade effect where interactions are strong enough to suppress double occupancy of a photonic lattice site. Here, we report the observation of quantum correlations between polaritons in a fiber cavity which spatially confines polaritons into an area of 3 $μ$m$^2$. Photon correlation measurements show that careful tuning of the coupled system allows for a modest photon blockade effect as evidenced by a reduction of simultaneous two-polariton generation probability by 5 %. Concurrently, our experiments provide an unequivocal measurement of the polariton interaction strength, thereby resolving the controversy stemming from recent experimental reports. Our findings constitute a first essential step towards the realization of strongly interacting photonic systems.

description: We perform a combined likelihood analysis of the latest cosmic microwave background anisotropy data and distant Type 1a Supernova data of Perlmutter etal (1998a). Our analysis is restricted to cosmological models where structure forms from adiabatic initial fluctuations characterised by a power-law spectrum with negligible tensor component. Marginalizing over other parameters, our best fit solution gives Omega_m = 0.25 (+0.18, -0.12) and Omega_Lambda = 0.63 (+0.17, -0.23) (95 % confidence errors) for the cosmic densities contributed by matter and a cosmological constant respectively. The results therefore strongly favour a nearly spatially flat Universe with a non-zero cosmological constant.

Experimental and computational modelling of collective cell migration in peripheral nerve repair
Creators: name: Whitby, Ariadne Melody
Publisher: name: Imperial College London
Year: 2017

description: A number of biological processes, such as embryonic development, cancer invasion and wound repair, rely on collective cell migration, a process of cells migrate together in sheets, strands or clusters. Peripheral nerves have a remarkable ability to regenerate and re-establish function after injury. Our lab has previously shown that this process depends on the collective migration of Schwann cell cords into the wound, which guide regrowing axons across the injury site to promote re-innervation. Cell-cell contact dependent signalling between Schwann cells and wound fibroblasts plays a critical role in this process by promoting cord formation and directional migration through Eph/ephrin-dependent cell sorting. However, how the interplay of homotypic and heterotypic cell-cell interactions regulates the coherent collective migration of Schwann cells or which molecular are effectors involved is not fully understood. We combine cell and molecular biology experiments with computational simulations to develop a novel computational model of peripheral nerve repair which simulates the interactions between Schwann cells and fibroblasts at the wound site. First, using methods from statistical physics we analyse experimental \emph{in vitro} data to parametrize our model. Then, we use the model to explore the theoretical requirements for an emerging coordination (i.e. formation of collectively migrating Schwann cell cords) in the system in order to better understand the mechanisms by which peripheral nerve repair occurs.

description: The Pandora's Box Problem, originally formalized by Weitzman in 1979, models selection from set of random, alternative options, when evaluation is costly. This includes, for example, the problem of hiring a skilled worker, where only one hire can be made, but the evaluation of each candidate is an expensive procedure. Weitzman showed that the Pandora's Box Problem admits an elegant, simple solution, where the options are considered in decreasing order of reservation value,i.e., the value that reduces to zero the expected marginal gain for opening the box. We study for the first time this problem when order - or precedence - constraints are imposed between the boxes. We show that, despite the difficulty of defining reservation values for the boxes which take into account both in-depth and in-breath exploration of the various options, greedy optimal strategies exist and can be efficiently computed for tree-like order constraints. We also prove that finding approximately optimal adaptive search strategies is NP-hard when certain matroid constraints are used to further restrict the set of boxes which may be opened, or when the order constraints are given as reachability constraints on a DAG. We complement the above result by giving approximate adaptive search strategies based on a connection between optimal adaptive strategies and non-adaptive strategies with bounded adaptivity gap for a carefully relaxed version of the problem.

description: We present results of near--IR long-slit spectroscopy in the J and K bands of the Seyfert 2 galaxies NGC 2110 and Circinus, investigating the gaseous distribution, excitation, reddening and kinematics. In NGC 2110, the emission line ratio [FeII]/Pa beta increases towards the nucleus (to ~ 7). The nuclear [Fe II]1.257 (microns) and Pa beta lines are broader (FWHM ~ 500 km/s) than the H2 (2.121) line (FWHM ~ 300 km/s). Both these results suggest that shocks, driven by the radio jet, are an important source of excitation of [Fe II]. The H2 excitation appears to be dominated by X-rays from the nucleus. In Circinus, both [FeII]/Pa beta and H2/Br gamma decrease from ~ 2 at 4 arcsec from the nucleus to nuclear values of ~ 0.6 and ~ 1, respectively, suggesting that the starburst dominates the nuclear excitation, while the AGN dominates the excitation further out (r > 2 arcsec). For both galaxies, the gaseous kinematics are consistent with circular rotation in the plane of the disk. Our rotation curves suggest that the nucleus (identified with the peak of the IR continuum) is displaced from the kinematic centre of the galaxies. This effect has been observed previously in NGC 2110 based on the kinematics of optical emission lines, but the displacement is smaller in the infrared, suggesting the effect is related to obscuration. The continuum J-K colours of the nuclear region indicate a red stellar population in NGC 2110 and a reddened young stellar population in Circinus. Right at the nucleus of both galaxies, the colours are redder, apparently a result of hot dust emission from the inner edge of a circumnuclear torus.

description: Using the space-time analogy, we compare the performance of quantum temporal imaging with its classical counterpart. We consider a temporal imaging scheme, based on the sum-frequency generation (SFG) time lens, but our results can be applied to other temporal imaging schemes such as, for instance, four-wave mixing. Extending the theory presented in our previous publications, in this paper we take into account the finite time aperture of the imaging system, characterized by its pupil function. Using the quantum theory, we obtain a unitary transformation of the quantum field from the input to the output of the imaging scheme and identify the contribution of the vacuum fluctuations missing in the classical theory. This contribution plays a key role in the quantum temporal imaging of nonclassical temporal waveforms, characterized by nonclassical fluctuations of the electromagnetic field. As an example, we consider quantum temporal imaging of broadband squeezed light and formulate the criteria for conservation of its squeezing properties at the output of the system.

description: For the large-scale linear discrete ill-posed problem $\min\|Ax-b\|$ or $Ax=b$ with $b$ contaminated by Gaussian white noise, the Lanczos bidiagonalization based Krylov solver LSQR and its mathematically equivalent CGLS, the Conjugate Gradient (CG) method implicitly applied to $A^TAx=A^Tb$, are most commonly used, and CGME, the CG method applied to $\min\|AA^Ty-b\|$ or $AA^Ty=b$ with $x=A^Ty$, and LSMR, which is equivalent to the minimal residual (MINRES) method applied to $A^TAx=A^Tb$, have also been choices. These methods exhibit typical semi-convergence feature, and the iteration number $k$ plays the role of the regularization parameter. However, there has been no definitive answer to the long-standing fundamental question: {\em Can LSQR and CGLS find 2-norm filtering best possible regularized solutions}? The same question is for CGME and LSMR too. At iteration $k$, LSQR, CGME and LSMR compute {\em different} iterates from the {\em same} $k$ dimensional Krylov subspace. A first and fundamental step towards to answering the above question is to {\em accurately} estimate the accuracy of the underlying $k$ dimensional Krylov subspace approximating the $k$ dimensional dominant right singular subspace of $A$. Assuming that the singular values of $A$ are simple, we present a general $\sinΘ$ theorem for the 2-norm distances between these two subspaces and derive accurate estimates on them for severely, moderately and mildly ill-posed problems. We also establish some relationships between the smallest Ritz values and these distances. Numerical experiments justify the sharpness of our results.

description: Understanding the normal-metal state transport in twisted bilayer graphene near magic angle is of fundamental importance as it provides insights into the mechanisms responsible for the observed strongly correlated insulating and superconducting phases. Here we provide a rigorous theory for phonon-dominated transport in twisted bilayer graphene describing its unusual signatures in the resistivity (including the variation with electron density, temperature, and twist angle) showing good quantitative agreement with recent experiments. We contrast this with the alternative Planckian dissipation mechanism that we show is incompatible with available experimental data. An accurate treatment of the electron-phonon scattering requires us to go well beyond the usual treatment, including both interband and intraband processes, considering the finite-temperature dynamical screening of the electron-phonon matrix element, and going beyond the linear Dirac dispersion. In addition to explaining the observations in currently available experimental data, we make concrete predictions that can be tested in ongoing experiments.

Emotional politics: the exploration of an occupy movement in Hong Kong

Publisher: name: University of Leicester

Subjects: Uncategorized

description: This thesis aims to explore the scale, duration, and intensity of the Umbrella Movement, which emerged in Hong Kong in 2014. Drawing from 60 in-depth interviews and related documentary analysis, this qualitative study examines why the participants decided to join a social movement that was defined by the government as illegal and how the movement maintained participants’ commitment so as to make it the longest-running and most intensive pro-democracy movement in Hong Kong history.The thesis demonstrates that collective identity functioned as a precondition explaining the large scale of participation. The study also showed that the occupied zone acted as a free space in constructing a new protest identity, which explained the participants’ intensive and long-lasting commitment in joining the movement. As a free space with culture and values opposed to the dominant ideology, the occupied zones generated emotional and relational transformative impacts on the participants, which led to the creation of a new protest identity. Their newly created collective identity transcended their diverse backgrounds, and they perceived the engagement as a pleasurable experience. This emotional benefit, together with the intensive interaction within the occupied zone, led to the formation of strong affective ties among the participants, which became an asset of the movement.My study demonstrates how the collective identity formed captured the emotional and spatial dimensions. It also enriches the analysis of the Occupy movements. This thesis argues that historical and cultural understanding of the occupied zones is undermined in most Occupy movement studies. Though the Umbrella Movement chose a financial hub as an occupied area, the reason was not to express opposition to economic inequality. Instead, it showed resistance to the policy of economic unification brought by decolonization. This thesis offers a new lens in understanding the symbolic meaning of free space created during the Occupy movement.

description: A celebrated impossibility result by Myerson and Satterthwaite (1983) shows that any truthful mechanism for two-sided markets that maximizes social welfare must run a deficit, resulting in a necessity to relax welfare efficiency and the use of approximation mechanisms. Such mechanisms in general make extensive use of the Bayesian priors. In this work, we investigate a question of increasing theoretical and practical importance: how much prior information is required to design mechanisms with near-optimal approximations?
 Our first contribution is a more general impossibility result stating that no meaningful approximation is possible without any prior information, expanding the famous impossibility result of Myerson and Satterthwaite.
 Our second contribution is that one {\em single sample} (one number per item), arguably a minimum-possible amount of prior information, from each seller distribution is sufficient for a large class of two-sided markets. We prove matching upper and lower bounds on the best approximation that can be obtained with one single sample for subadditive buyers and additive sellers, regardless of computational considerations.
 Our third contribution is the design of computationally efficient blackbox reductions that turn any one-sided mechanism into a two-sided mechanism with a small loss in the approximation, while using only one single sample from each seller. On the way, our blackbox-type mechanisms deliver several interesting positive results in their own right, often beating even the state of the art that uses full prior information.

description: The atmospheres of extrasolar giant planets are modeled with various effective temperatures and gravities, with and without clouds. Bond albedos are computed by calculating the ratio of the flux reflected by a planet (integrated over wavelength) to the total stellar flux incident on the planet. This quantity is useful for estimating the effective temperature and evolution of a planet. We find it is sensitive to the stellar type of the primary. For a 5 M_Jup planet the Bond albedo varies from 0.4 to 0.3 to 0.06 as the primary star varies from A5V to G2V to M2V in spectral type. It is relatively insensitive to the effective temperature and gravity for cloud--free planets. Water clouds increase the reflectivity of the planet in the red, which increases the Bond albedo. The Bond albedo increases by an order of magnitude for a 13 M_Jup planet with an M2V primary when water clouds are present. Silicate clouds, on the other hand, can either increase or decrease the Bond albedo, depending on whether there are many small grains (the former) or few large grains (the latter).

description: We define the Uhlmann number as an extension of the Chern number, and we use this quantity to describe the topology of 2D translational invariant Fermionic systems at finite temperature. We consider two paradigmatic systems and we study the changes in their topology through the Uhlmann number. Through the linear response theory we linked two geometrical quantities of the system, the mean Uhlmann curvature and the Uhlmann number, to directly measurable physical quantities, i.e. the dynamical susceptibility and to the dynamical conductivity, respectively.

Efficiently learning efficient programs
Creators: name: Cropper, Andrew
Publisher: name: Imperial College London
Year: 2017

description: Discovering efficient algorithms is central to computer science. In this thesis, we aim to discover efficient programs (algorithms) using machine learning. Specifically, we claim we can efficiently learn programs (Claim 1), and learn efficient programs (Claim 2). In contrast to universal induction methods, which learn programs using only examples, we introduce program induction techniques which additionally use background knowledge to improve learning efficiency. We focus on inductive logic programming (ILP), a form of program induction which uses logic programming to represent examples, background knowledge, and learned programs. In the first part of this thesis, we support Claim 1 by using appropriate background knowledge to efficiently learn programs. Specifically, we use logical minimisation techniques to reduce the inductive bias of an ILP learner. In addition, we use higher-order background knowledge to extend ILP from learning first-order programs to learning higher-order programs, including the support for higher-order predicate invention. Both contributions reduce learning times and improve predictive accuracies. In the second part of this thesis, we support Claim 2 by introducing techniques to learn minimal cost logic programs. Specifically, we introduce Metaopt, an ILP system which, given sufficient training examples, is guaranteed to find minimal cost programs. We show that Metaopt can learn minimal cost robot strategies, such as quicksort, and minimal time complexity logic programs, including non-deterministic programs. Overall, the techniques introduced in this thesis open new avenues of research in computer science and raise the potential for algorithm designers to discover novel efficient algorithms, for software engineers to automate the building of efficient software, and for AI researchers to machine learn efficient robot strategies.

description: Our computations show that there is a total of $40$ pairs of degree six coprime polynomials $f,g$ where $f(x)=(x-1)^6$, $g$ is a product of cyclotomic polynomials, $g(0)=1$ and $f,g$ form a primitive pair. The aim of this article is to determine whether the corresponding $40$ symplectic hypergeometric groups with a maximally unipotent monodromy follow the same dichotomy between arithmeticity and thinness that holds for the $14$ symplectic hypergeometric groups corresponding to the pairs of degree four polynomials $f,g$ where $f(x)=(x-1)^4$ and $g$ is as described above. As a result we prove that at least $18$ of these $40$ groups are arithmetic in $\mathrm{Sp}(6)$.
 In addition, we extend our search to all degree six symplectic hypergeometric groups. We find that there is a total of $458$ pairs of polynomials (up to scalar shifts) corresponding to such groups. For $211$ of them, the absolute values of the leading coefficients of the difference polynomials $f-g$ are at most $2$ and the arithmeticity of the corresponding groups follows from Singh and Venkataramana, while the arithmeticity of one more hypergeometric group follows from Detinko, Flannery and Hulpke.
 In this article, we show the arithmeticity of $160$ of the remaining $246$ hypergeometric groups.

description: We study the equation of state of pure SU($2$) gauge theory using Monte Carlo simulations. The scale-setting of lattice parameters has been carried by using the gradient flow. We propose a reference scale $t_0$ for the SU($2$) gauge theory satisfying $t^2 \langle E \rangle|_{t=t_0} =0.1$, which is fixed by a natural scaling-down of the standard $t_0$-scale for the SU($3$) case based on perturbative analyses. We also show the thermodynamic quantities as a function of $T/T_c$, which are derived by the energy-momentum tensor using the small flow-time expansion of the gradient flow.

Novel methodologies for the synthesis of highly substituted aromatic rings: the development of a microwave mediated approach
Creators: name: Padgham, Alex
Publisher: name: Imperial College London
Year: 2017

description: An interesting transformation involving palladium was recently discovered by the Parsons group, which entailed the cyclisation and fragmentation of furan starting materials to afford highly substituted benzene compounds. The early aim of the project was to investigate the presence of intermediates in the reaction mixture, in an attempt to determine a possible mechanistic pathway. These results laid the foundation for future research; it was subsequently postulated that a similar reaction could be achieved under purely thermal conditions. Investigations led to the discovery that microwave irradiation could successfully initiate the thermal cyclisation of the designed precursors, resulting in moderate to good yields of highly substituted benzene products. Further studies found that, by replacing the terminal alkyne with a nitrile group, a highly substituted pyridine compound could be isolated, and other analogues were investigated, though ultimately unsuccessful. During investigations of the scope of the cyclisation, it was also found that the same conditions could thermally cyclise diyne compounds into furan products: a tricyclic furan was formed from a diyne ether furan precursor, and simple diynes were cyclised into aromatic products and simple bicycles.
