description: I derive a second-order local relation between the REDSHIFT-space mass density field and the REAL-space velocity field. This relation can be useful for comparisons between the cosmic density and peculiar velocity fields, for a number of reasons. First, relating the real-space velocity directly to the redshift-space density enables one to avoid the Omega-dependent reconstruction of the density field in real space. Secondly, the reconstruction of the three-dimensional velocity field in redshift space, questionable because of its vorticity, is also unnecessary. Finally, a similar relation between the GALAXY density field and the velocity field offers a way to break the Omega-bias degeneracy in density--velocity comparisons, when combined with an additional measurement of the redshift-space galaxy skewness. I derive the latter relation under the assumption of nonlinear but local bias; accounting for stochasticity of bias is left for further study.

description: We have selected the seven most well-defined WR ring nebulae in the LMC (Br 2, Br 10, Br 13, Br 40a, Br 48, Br 52, and Br 100) to study their physical nature and evolutionary stages. New CCD imaging and echelle observations have been obtained for five of these nebulae; previous photographic imaging and echelle observations are available for the remaining two nebulae. Using the nebular dynamics and abundances, we find that the Br 13 nebula is a circumstellar bubble, and that the Br 2 nebula may represent a circumstellar bubble merging with a fossil main-sequence interstellar bubble. The nebulae around Br 10, Br 52, and Br 100 all show influence of the ambient interstellar medium. Their regular expansion patterns suggest that they still contain significant amounts of circumstellar material. Their nebular abundances would be extremely interesting, as their central stars are WC5 and WN3-4 stars whose nebular abundances have not been derived previously. Intriguing and tantalizing implications are obtained from comparisons of the LMC WR ring nebulae with ring nebulae around Galactic WR stars, Galactic LBVs, LMC LBVs, and LMC BSGs; however, these implications may be limited by small-number statistics. A SNR candidate close to Br 2 is diagnosed by its large expansion velocity and nonthermal radio emission. There is no indication that Br 2's ring nebula interacts dynamically with this SNR candidate.

description: One central problem in real algebraic geometry is to classify the real structures of a given complex manifold. We address this problem for compact hyperkähler manifolds by showing that any such manifold admits only finitely many real structures up to equivalence. We actually prove more generally that there are only finitely many, up to conjugacy, faithful finite group actions by holomorphic or anti-holomorphic automorphisms (the so-called Klein actions). In other words, the automorphism group and the Klein automorphism group of a compact hyperkähler manifold contain only finitely many conjugacy classes of finite subgroups. We furthermore answer a question of Oguiso by showing that the automorphism group of a compact hyperkähler manifold is finitely presented.

description: By accumulating all available radial velocity data and combining it with our own spectroscopy we present a new and improved ephemeris for Cygnus X-1 (V1357 Cygni/HDE226868). We initially calculate an orbital period of 5.599847+/-0.000018.days and then, by including the more recent radial velocities of LaSala et al. (1998) and Sowers et al.(1998) we refine this to 5.599829+/-0.000016 days. Using 27 years' worth of photometry, we also calculate a photometric period of 5.599836+/-0.000024 - remarkably similar to the spectroscopic one.

Molecular epidemiology of azole-resistant Aspergillus fumigatus in respiratory infections
Creators: name: Abdolrasouli, Alireza
Publisher: name: Imperial College London
Year: 2018

description: Aspergillus fumigatus is a ubiquitous ascomycete mould and the primary cause of aspergillosis which varies in severity and clinical presentation. Triazoles have been the most widely used antifungal agents in prophylaxis and treatment of Aspergillus-related infections. Since the late 2000s there has been a steady increase in the number of reported resistance to azole antifungals in A. fumigatus, causing a major clinical concern with subsequent treatment failure among some patients. This PhD aimed to clarify the epidemiology of azole-resistant A. fumigatus at a regional level in West London. Firstly, the prevalence of azole-resistance in a large collection of clinical A. fumigatus isolates collected over a 17 year period (1998 - 2017) was determined, which surprisingly found a low level of resistance among mixed patient population. Conversely, a two-year (2015 - 2017) passive surveillance of isolates obtained from a specialist cardio-thoracic centre located in the same region, revealed an alarmingly high prevalence of resistance mostly among patients with cystic fibrosis. Secondly, to evaluate the application of whole-genome sequencing (WGS) in interrogation of azole-resistant A. fumigatus, a global panel of 24 isolates was analysed. WGS demonstrated that SNP analysis was able to accurately identify polymorphisms in the cyp51A gene conferring resistance to triazole antifungals. The WGS further associated to a globally panmictic population in A. fumigatus. In London, WGS revealed that environmentally-driven TR34/L98H, G54W and P216L were common alterations in cyp51A. A novel TR34/L98H/T289A/G448S polymorphism was discovered here causing a pan-azole-resistant phenotype. Phylogenomic analysis of sequenced genomes including London isolates, showed two novel major clades; one clade contains azole-resistant A. fumigatus with TR34/L98H allele, while the second clade consists of most azole-susceptible isolates. Finally, this PhD characterises the phenotypic heterogeneity of A. fumigatus and showed that acidic pH tolerance exists among some clinical A. fumigatus isolates. Furthermore, phenotypic switching accompanied with enhanced growth rate found in one azole-resistant isolate indicates that azole-resistant A. fumigatus has high fitness in azole-free environments and confirms that sexual reproduction leads to transmission of TR34/L98H allele in the absence of exposure to medical or fungicidal azole agents. Overall these findings indicate that prevalence of azole-resistance is linked to specific patient populations in regional level. Presence of TR34/L98H among azole-resistant isolates suggests a spillover of environmentally acquired antifungal resistance into susceptible patient cohorts.

description: Site-occupation embedding theory (SOET) is an in-principle-exact multi-determinantal extension of density-functional theory for model Hamiltonians. Various extensions of recent developments in SOET [Senjean et al., Phys. Rev. B 97, 235105 (2018)] are explored in this work. An important step forward is the generalization of the theory to multiple impurity sites. We also propose a new single-impurity density-functional approximation (DFA) where the density-functional impurity correlation energy of the two-level (2L) Hubbard system is combined with the Bethe ansatz local density approximation (BALDA) to the full correlation energy of the (infinite) Hubbard model. In order to test the new DFAs, the impurity-interacting wavefunction has been computed self-consistently with the density matrix renormalization group method (DMRG). Double occupation and per-site energy expressions have been derived and implemented in the one-dimensional case. A detailed analysis of the results is presented, with a particular focus on the errors induced either by the energy functionals solely or by the self-consistently converged densities. Among all the DFAs (including those previously proposed), the combined 2L-BALDA is the one that performs the best in all correlation and density regimes. Finally, extensions in new directions, like a partition-DFT-type reformulation of SOET, a projection-based SOET approach, or the combination of SOET with Green functions, are briefly discussed as a perspective.

High Angular Resolution JHK Imaging of the Centers of the Metal-Poor Globular Clusters NGC5272 (M3), NGC6205 (M13), NGC6287, and NGC6341 (M92)

description: The Canada-France-Hawaii Telescope (CFHT) Adaptive Optics Bonnette (AOB) has been used to obtain high angular resolution JHK images of the centers of the metal-poor globular clusters NGC5272 (M3), NGC6205 (M13), NGC6287, and NGC6341 (M92). The color-magnitude diagrams (CMDs) derived from these data include the upper main sequence and most of the red giant branch (RGB), and the cluster sequences agree with published photometric measurements of bright stars in these clusters. The photometric accuracy is limited by PSF variations, which introduce systematic errors of a few hundredths of a magnitude near the AO reference star. The clusters are paired according to metallicity, and the near-infrared CMDs and luminosity functions are used to investigate the relative ages within each pair. The near-infrared CMDs provide the tightest constraints on the relative ages of the classical second parameter pair NGC5272 and NGC6205, and indicate that these clusters have ages that differ by no more than +/- 1 Gyr. These results thus support the notion that age is not the second parameter. We tentatively conclude that NGC6287 and NGC6341 have ages that differ by no more than +/- 2 Gyr. However, the near-infrared spectral energy distributions of stars in NGC6287 appear to differ from those of stars in outer halo clusters, bringing into question the validity of this age estimate.

Quasi-thermal Comptonization and gamma-ray bursts
Creators: name: Ghisellini, G.

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

description: Quasi-thermal Comptonization in internal shocks formed between relativistic shells can account for the high energy emission of gamma-ray bursts. This is in fact the dominant cooling mechanism if the typical energy of the emitting particles is achieved either through the balance between heating and cooling or as a result of electron-positron pair production. Both processes yield sub or mildly relativistic energies. In this case the synchrotron spectrum is self-absorbed, providing the seed soft photons for the Comptonization process, whose spectrum is flat [F(v) ~ const], ending either in an exponential cutoff or a Wien peak, depending on the scattering optical depth of the emitting particles. Self-consistent particle energy and optical depth are estimated and found in agreement with the observed spectra.

Hubbard-like hamiltonians for interacting electrons in s, p and d orbitals
Creators: name: Coury, Marc
Publisher: name: Imperial College London
Year: 2019

description: Hubbard-like Hamiltonians are widely used to describe on-site Coulomb interactions in magnetic and strongly correlated solids, but there is much confusion in the literature surrounding the form of these Hamiltonians for shells of p and d orbitals. This thesis derives the most general s, p and d orbital Hubbard-like Hamiltonians consistent with the relevant symmetries, and presents them in ways convenient for many body and meanfield calculations. Analytical solutions are found for s orbital dimers using the full configuration interaction and tight binding methods. The tight binding programme Python Noncollinear Magnetic Tight Binding [1] (PyLATO), developed for this thesis, is introduced and explained. Computational results are found for s, p and d orbital dimers, using the full configuration interaction and tight binding methods, for the Hamiltonians derived herein and the vector Stoner Hamiltonian. Noticeable differences were found between the results of the Hamiltonians derived herein and the vector Stoner Hamiltonian for the magnetic correlation of the groundstate, the time evolution of excited states, and the electronic heat capacity.

Static analysis for facilitating secure and reliable software
Creators: name: Siavvas, Miltiadis
Publisher: name: Imperial College London
Year: 2019

description: Software security and reliability are aspects of major concern for software development enterprises that wish to deliver dependable software to their customers. Several static analysis-based approaches for facilitating the development of secure and reliable software have been proposed over the years. The purpose of the present thesis is to investigate these approaches and to extend their state of the art by addressing existing open issues that have not been sufficiently addressed yet. To this end, an empirical study was initially conducted with the purpose to investigate the ability of software metrics (e.g., complexity metrics) to discriminate between different types of vulnerabilities, and to examine whether potential interdependencies exist between different vulnerability types. The results of the analysis revealed that software metrics can be used only as weak indicators of specific security issues, while important interdependencies may exist between different types of vulnerabilities. The study also verified the capacity of software metrics (including previously uninvestigated metrics) to indicate the existence of vulnerabilities in general. Subsequently, a hierarchical security assessment model able to quantify the internal security level of software products, based on static analysis alerts and software metrics is proposed. The model is practical, since it is fully-automated and operationalized in the form of individual tools, while it is also sufficiently reliable since it was built based on data and well-accepted sources of information. An extensive evaluation of the model on a large volume of empirical data revealed that it is able to reliably assess software security both at product- and at class-level of granularity, with sufficient discretion power, while it may be also used for vulnerability prediction. The experimental results also provide further support regarding the ability of static analysis alerts and software metrics to indicate the existence of software vulnerabilities. Finally, a mathematical model for calculating the optimum checkpoint interval, i.e., the checkpoint interval that minimizes the execution time of software programs that adopt the application-level checkpoint and restart (ALCR) mechanism was proposed. The optimum checkpoint interval was found to depend on the failure rate of the application, the execution cost for establishing a checkpoint, and the execution cost for restarting a program after failure. Emphasis was given on programs with loops, while the results were illustrated through several numerical examples.

description: In this work we develop an innovative hierarchical clustering method to divide a sample of undirected weighted networks into groups. The methodology consists of two phases: the first phase is aimed at putting the single networks in a broader framework by including the characteristics of the population in the data, while the second phase creates a subdivision of the sample on the basis of the similarity between the community structures of the processed networks. Starting from the representation of the team's playing style as a network, we apply the method to group the Italian Serie A teams' performances and consequently detect the main 15 tactics shown during the 2015-2016 season. The information obtained is used to verify the effect of the styles of play on the number of goals scored, and we prove the key role of one of them by implementing an extension of the Dixon and Coles model (Dixon and Coles, 1997).

description: ISO-SWS spectroscopy of the WR galaxy NGC5253 is presented, and analysed to provide estimates of its hot young star population. Our approach differs from previous investigations in that we are able to distinguish between the regions in which different infrared fine-structure lines form, using complementary ground-based observations. The high excitation nebular [SIV] emission is formed in a very compact region, which we attribute to the central super-star-nucleus, and lower excitation [NeII] nebular emission originates in the galactic core. We use photo-ionization modelling coupled with the latest theoretical O-star flux distributions to derive effective stellar temperatures and ionization parameters of Teff>38kK, logQ=8.25 for the compact nucleus, with Teff=35kK, logQ<8 for the larger core. Results are supported by more sophisticated calculations using evolutionary synthesis models. We assess the contribution that Wolf-Rayet stars may make to highly ionized nebular lines (e.g. [OIV]). From our Br(alpha) flux, the 2" nucleus contains the equivalent of approximately 1000 O7V star equivalents and the starburst there is 2-3Myr old; the 20" core contains about 2500 O7V star equivalents, with a representative age of 5Myr. The Lyman ionizing flux of the nucleus is equivalent to the 30 Doradus region. These quantities are in good agreement with the observed mid-IR dust luminosity of 7.8x10^8 L(sun) Since this structure of hot clusters embedded in cooler emission may be common in dwarf starbursts, observing a galaxy solely with a large aperture may result in confusion. Neglecting the spatial distribution of nebular emission in NGC5253, implies `global' stellar temperatures (or ages) of 36kK (4.8Myr) and 39kK (2.9 or 4.4Myr) from the observed [NeIII/II] and [SIV/III] line ratios, assuming logQ=8.

Optimal logistics for modular construction
Creators: name: Hsu, Pei-Yuan
Publisher: name: Imperial College London
Year: 2019

description: The construction sector is currently undergoing a shift from in-situ construction to modular building systems that take advantage of modern prefabrication techniques. Long established conventional on-site building construction practices are thus being replaced by processes imported from the manufacturing sector, where component fabrication takes place within a factory environment. In this context, similar to manufacturing industries, the productivity of building components fluctuates, owing to human error and machine malfunction. Since the site demand must always be met, outsourcing manufacturing is employed to supplement the uncertain self-production. As a result of these transformations, the current construction supply chains, which have focused on the delivery of raw materials to sites, are no longer apt and need to make way to new, strengthened, and time-critical logistics systems. Moreover, previous studies have indicated that construction site delays constitute the most significant cause of schedule deviations. Thus, the primary reasons for causing schedule deviation need to be identified. In reality, owing to the complex structure of construction projects and long execution time, non-conformance in schedules occurs by a chain of events. Therefore, this research intends to investigate the factors causing schedule deviation in construction projects and understand the cause-effect relationships between the events leading to delays by implementing fault tree analysis. The primary aim of this research is to develop mathematical models by mixed-integer linear programming, two-stage stochastic programming and robust optimisation for revealing optimal logistic configurations for modular construction projects under various prevalent site demand perturbations. The models’ outputs encompass the most favourable manufacturing, storage, transportation and outsourcing schemes, along with considerations of the best consolidation centre location for yielding the lowest modular construction supply chain operational cost. The applications of case studies demonstrate that the proposed models are effective and can serve as the foundation for a decision support system that optimises modular construction logistics under operational uncertainty.

description: The 6th generation (6G) wireless networks will likely to support a variety of capabilities beyond communication, such as sensing and localization, through the use of communication networks empowered by advanced technologies. Integrated sensing and communication (ISAC) has been recognized as a critical technology as well as an usage scenario for 6G, as widely agreed by leading global standardization bodies. ISAC utilizes communication infrastructure and devices to provide the capability of sensing the environment with high resolution, as well as tracking and localizing moving objects nearby. Meeting both the requirements for communication and sensing simultaneously, ISAC based approaches celebrate the advantages of higher spectral and energy efficiency compared to two separate systems to serve two purposes, and potentially lower costs and easy deployment. A key step towards the standardization and commercialization of ISAC is to carry out comprehensive field trials in practical networks, such as the 5th generation (5G) network, to demonstrate its true capacities in practical scenarios. In this paper, an ISAC based outdoor multi-target detection, tracking and localization approach is proposed and validated in 5G networks. The proposed system comprises of 5G base stations (BSs) which serve nearby mobile users normally, while accomplishing the task of detecting, tracking and localizing drones, vehicles and pedestrians simultaneously. Comprehensive trial results demonstrate the relatively high accuracy of the proposed method in practical outdoor environment when tracking and localizing single targets and multiple targets.

description: The SH0ES collaboration Hubble constant determination is in a ${\sim}5σ$ difference with the $Planck$ value, known as the Hubble tension. The accuracy of the Hubble constant measured with extragalactic Cepheids depends on robust stellar-crowding background estimation. Riess et al. (R20) compared the light curves amplitudes of extragalactic and MW Cepheids to constrain an unaccounted systematic blending bias, $γ=-0.029\pm0.037\,\rm{mag}$, which cannot explain the required, $γ=0.24\pm0.05\,\rm{mag}$, to resolve the Hubble tension. Further checks by Riess et al. demonstrate that a possible blending is not likely related to the size of the crowding correction. We repeat the R20 analysis, with the following main differences: (1) we limit the extragalactic and MW Cepheids comparison to periods $P\lesssim50\,\rm{d}$, since the number of MW Cepheids with longer periods is minimal; (2) we use publicly available data to recalibrate amplitude ratios of MW Cepheids in standard passbands; (3) we remeasure the amplitudes of Cepheids in NGC 5584 and NGC 4258 in two HST filters ($F555W$ and $F350LP$) to improve the empirical constraint on their amplitude ratio $A^{555}/A^{350}$. We show that the filter transformations introduce an ${\approx}0.04\,\rm{mag}$ uncertainty in determining $γ$, not included by R20. While our final estimate, $γ=0.013\pm0.057\,\rm{mag}$, is consistent with the value derived by R20 and is consistent with no bias, the error is somewhat larger, and the best fitting value is shifted by ${\approx}0.04\,\rm{mag}$ and closer to zero. Future observations, especially with JWST, would allow better calibration of $γ$.

Dynamic response of steel monolithic plated structures subjected to localised blast loads
Creators: name: Mehreganian, Navid
Publisher: name: Imperial College London
Year: 2018

description: This thesis investigates the nonlinear dynamic response of the steel monolithic square plated structures due to localised blast loads, such as those emanating from close-in charges. Such target plates are assumed to be made of novel high strength ARMOX steel material types manufactured by SSAB® as well as conventional mild steel. A detailed review of earlier works in the literature is presented on the experimental, numerical and theoretical methods of analysis to predict the response of beams, circular and quadrangular plates subject to blast and impact loads. The large scatter of data from the above analyses has been cast in dimensionless forms to correlate between the methods of predicting the response. The review concludes that, the choice of material type as well as the intrinsic complexity associated with the load type make the response of the structure inherently different to those of plated elements made of more conventional grade metals. Based on the state-of-the-art Digital Image Correlation experimental testing conducted in the Blast Impact and Survivability Research Unit in University of Cape Town, various proposed numerical models have been validated. These include advanced techniques to model the fluid structure interactions. This led to discerning the parameters that influence the plastic response. Empirical relations in dimensionless form have been proposed which pass through most scattered data from numerical and experimental results. A prompt observation is that assessing the plastic response of the structures to localised blasts necessitates understanding the underlying patterns and laws of plastic response. Such understanding is gained by theoretical methods with idealisations of the material or the structural response. This leads to theoretical studies using the principles of virtual velocities assuming constitutive framework of limit analysis, i.e. rigid, perfectly plastic behaviour. While appreciating the limitations of current theoretical models, a comprehensive approach is undertaken to explore the response of the plates of various boundary conditions, distinguished in terms of their thicknesses, i.e. thick, moderately thick and thin plates. Furthermore, the nonlinear elastic response of the plates has been examined, leading to a unified theoretical solution of elastic-perfectly plastic systems. On the basis of the existing work in the literature, a method to mathematically describe the parameters that characterise the blast load itself and the structure impacted whereupon with a given charge geometry, stand off and material type is presented and validated with numerical models. Based on the dimensionless study, single parameters to predict the rupture impulse has been determined.

description: Increasing interest in securing the Android ecosystem has spawned numerous efforts to assist app developers in building secure apps. These efforts have resulted in tools and techniques capable of detecting vulnerabilities (and malicious behaviors) in apps. However, there has been no evaluation of the effectiveness of these tools and techniques in detecting known vulnerabilities. The absence of such evaluations puts app developers at a disadvantage when choosing security analysis tools to secure their apps. In this regard, we evaluated the effectiveness of vulnerability detection tools for Android apps. We reviewed 64 tools and empirically evaluated 14 vulnerability detection tools (incidentally along with five malicious behavior detection tools) against 42 known unique vulnerabilities captured by Ghera benchmarks, which are composed of both vulnerable and secure apps. Of the 24 observations from the evaluation, the main observation is existing vulnerability detection tools for Android apps are very limited in their ability to detect known vulnerabilities -- all of the evaluated tools together could only detect 30 of the 42 known unique vulnerabilities. More effort is required if security analysis tools are to help developers build secure apps. We hope the observations from this evaluation will help app developers choose appropriate security analysis tools and persuade tool developers and researchers to identify and address limitations in their tools and techniques. We also hope this evaluation will catalyze or spark a conversation in the software engineering and security communities to require a more rigorous and explicit evaluation of security analysis tools and techniques.

description: A major recent development in extragalactic astronomy has been the discovery of a population of galaxies that are luminous at submillimetre wavelengths. Estimates of their spectral energy distributions suggest that these galaxies are the high-redshift analogues of the ultraluminous infrared galaxies (ULIGs) observed locally. We identify plausible (but non-unique) redshift-dependent galaxy luminosity functions that are consistent with both source counts at 2800, 850, 450 and and 175 microns, and far-infrared background radiation intensities at 850, 240 and 140 microns. In all our models, most of the submillimetre-luminous sources are distant galaxies with high bolometric luminosities >= 10^12 L_sun. As for many local ULIGs it is not possible to determine whether these luminous galaxies are powered by starbursts, like the local galaxy Arp 220, or by active galactic nuclei (AGN), like the local galaxy Markarian 231. If the submillimetre-luminous galaxies are all starbursts, then we predict that the fraction of the cosmic star-formation rate in these objects is large, but but does not necessarily dominate the star-formation rate of the Universe at any redshift. Only a few per cent by mass of the present-epoch spheroidal stellar population would have been formed in such a population of star-forming galaxies, consistent with constraints on the number of galaxies with old stellar populations in the field at low and intermediate redshift derived from K-band surves. If the submillimetre-luminous galaxies are all powered by AGN, then the comoving density of supermassive black holes onto which material is accreting at high redshift probably equals no more than a few per cent of the local density of massive dark objects.

On the non-linear hydrodynamic stability of thin Keplerian disks

description: The non-linear hydrodynamic stability of thin, compressible, Keplerian disks is studied on the large two-dimensional compressible scale, using a high-order accuracy spectral method. We show that purely hydrodynamic perturbations, while developing initially into sheared disturbances or coherent vortices, do not evolve into a self-sustained turbulence. This is in complete agreement with the conclusions of Balbus and Hawley (1998). We demonstrate that, temporarily, energy is being transferred to the largest scale mode (before dissipating). In the case of an inner reflecting boundary condition it is found that the innermost disk is globally unstable to non-axisymmetric modes which can evolve into turbulence. However, this turbulence is not expected to play a major role in angular momentum transport in the disk.

description: Projective measurements in random quantum circuits lead to a rich breadth of entanglement phases and extend the realm of non-unitary quantum dynamics. Here we explore the connection between measurement-only quantum circuits in one spatial dimension and the statistical mechanics of loop models in two dimensions. While Gaussian Majorana circuits admit a microscopic mapping to loop models, for non-Gaussian, i.e., generic Clifford, circuits a corresponding mapping may emerge only on a coarse grained scale. We then focus on a fundamental symmetry of loop models: the orientability of world lines. We discuss how orientability enters in the measurement framework, acting as a separatrix for the universal long-wavelength behavior in a circuit. When orientability is broken, the circuit falls into the universality class of closely packed loops with crossings (CPLC) and features a Goldstone phase with a peculiar, universal $\log^2(L)$-scaling of the entanglement entropy. In turn, when orientability is preserved, the long-wavelength behavior of the circuit mimics that of (coupled) two-dimensional Potts models. We demonstrate the strength of the loop model approach by numerically simulating a variety of measurement-only Clifford circuits. Upon varying the set of measured operators, a rich circuit dynamics is observed, ranging from CPLC to the $1$-state Potts model (percolation), the $2$-state Potts model (Ising) and coupled Potts models (BKT) universality class. Loop models thus provide a handle to access a large class of measurement-only circuits and yield a blueprint on how to realize desired entanglement phases by measurement.

description: With the emergence of communication services with stringent requirements such as autonomous driving or on-flight Internet, the sixth-generation (6G) wireless network is envisaged to become an enabling technology for future transportation systems. In this paper, two ways of interactions between 6G networks and transportation are extensively investigated. On one hand, the new usage scenarios and capabilities of 6G over existing cellular networks are firstly highlighted. Then, its potential in seamless and ubiquitous connectivity across the heterogeneous space-air-ground transportation systems is demonstrated, where railways, airplanes, high-altitude platforms and satellites are investigated. On the other hand, we reveal that the introduction of 6G guarantees a more intelligent, efficient and secure transportation system. Specifically, technical analysis on how 6G can empower future transportation is provided, based on the latest research and standardization progresses in localization, integrated sensing and communications, and security. The technical challenges and insights for a road ahead are also summarized for possible inspirations on 6G enabled advanced transportation.

Regulation of GLP-1R signalling by endocytic membrane trafficking and its significance for pancreatic beta-cell insulin secretion
Creators: name: Buenaventura, Teresa
Publisher: name: Imperial College London
Year: 2019

description: The G protein-coupled glucagon-like peptide-1 receptor (GLP-1R) regulates glucose homeostasis by potentiating pancreatic insulin secretion, representing a key target for type 2 diabetes (T2D) treatment. Upon agonist-induced GLP-1R plasma membrane signalling, the GLP-1R enters the endocytic pathway where it is sorted to recycling and/or degradative compartments in a regulated manner. Since the endocytic pathway tightly regulates GPCR activity, understanding the mechanisms that control agonist-mediated GLP-1R trafficking might lead to identification of new T2D therapeutic targets and/or development of improved GLP-1R agonists. Herein, we have screened an siRNA library of GPCR trafficking regulators with the aim of identifying factors capable of controlling GLP-1R activity and pancreatic -cell responses. Based on their effect on exendin-4-induced insulin secretion, we have identified five factors [clathrin, dynamin1, AP2, and sorting nexins (SNXs) SNX27 and SNX1] that negatively regulate, and four [huntingtin-interacting protein 1 (HIP1), HIP14, G protein-coupled receptor associated sorting protein-1 (GASP-1), and Neural Precursor Cell Expressed, Developmentally Down-Regulated 4 (Nedd4)], that enhance GLP-1R activity. Amongst these, we selected three candidates (HIP1, SNX1 and SNX27) for further characterisation. HIP1 was found to modulate GLP-1R G protein coupling while concomitantly controlling GLP-1R internalisation, while the two SNXs were shown to control GLP-1R endosomal sorting, affecting GLP-1R recycling versus degradation rates and determining endosomal and cell surface responses. In parallel, we investigated the role of the plasma membrane lipid composition on GLP-1R signalling and trafficking. Upon ligand binding, GLP-1R was shown to undergo palmitoylation and partitioning into specific cholesterol-enriched plasma membrane nanodomains, leading to GLP-1R signal transduction and cholesterol-dependent internalisation. This process was controlled by specific agonist binding kinetics and positive allosteric modulation. We have therefore identified key endocytic factors that determine GLP-1R activity and -cell incretin responses. Furthermore, we have demonstrated that both GLP-1R activity and trafficking are modulated by interactions with the surrounding lipid bilayer.
