Endothelial derived vesicles mediate podocyte dysfunction
Creators: name: Hill, Nicola Rachel
Publisher: name: Imperial College London
Year: 2018

description: The transfer of intracellular components, such as mRNA and miRNA via extracellular vesicles (EVs) is thought to facilitate cell-to-cell communication and may play a role in modulation and progression of kidney disease. EVs can bind to or be incorporated into a recipient cell, where they deliver their functional intracellular content which can result in molecular changes to the recipient cell. Several miRNAs have important roles in the pathogenesis of different types of chronic kidney disease (CKD) including various types of glomerulonephritis (GN). The kidneys glomerular filtration barrier (GFB) is composed of podocytes, glomerular basement membrane (GBM) and endothelium with its glycocalyx. Podocytes are crucial in maintaining the integrity of the GBM, and a decline in renal function occurs when podocytes become damaged or are lost. Podocytes and glomerular endothelial cells can communicate during renal disease; however, very little is known about how extracellular signals from the microenvironment regulate podocyte activity. This study proposes that GEnCs secrete EVs; these small vesicles, approximately 100nm in diameter were visualised by LM10 NanoSight technology microscopy and purified by ultracentrifugation. As detected by western blotting, EVs expressed protein markers, CD63 and TSG101 and whether unstimulated or stimulated with glucose, LPS or puromycin aminonucleoside (PAN), glomerular endothelial cells secreted equivalent numbers of EVs. Upon incubation with activated glomerular endothelial cell EVs, podocyte miRNA and mRNA expression changed significantly. Podocyte function was modulated, including dysregulation of the actin cytoskeleton, increased OXPHOS, mitochondrial activation, ROS production, alongside a decrease in VEGF secretion. miR-200C-3p was upregulated in podocytes upon incubation with EVs isolated from glucose and PAN treated glomerular endothelial cells. Overexpression of miR-200C-3p caused a downregulation of podocyte VEGF production. From the data, I conclude that activated glomerular endothelial cell EVs cause podocyte functional changes including downregulation of VEGF and may deliver a variety of miRNA’s including miR-200C-3p.
Investigating the physiological role of glucokinase in the nucleus tractus solitarius and the paraventricular nucleus in the regulation of energy homeostasis
Creators: name: De Backer, Ivan
Publisher: name: Imperial College London
Year: 2017

description: Chronically high circulating glucose levels can lead to metabolic problems such as Type II Diabetes Mellitus (T2DM). Plasma glucose levels are constantly monitored by a process named glucose-sensing. Glucokinase (GK) is a key glucose-sensing enzyme and is expressed in various areas of the brain associated with the control of energy homeostasis. It has been detected in the nucleus tractus solitarius (NTS) and the paraventricular nucleus (PVN) but its physiological role in these nuclei in the regulation of energy homeostasis is unclear. GK’s function in the NTS and PVN was determined by both down-regulating and up-regulating its expression in these nuclei using a viral vector encoding glucokinase antisense or sense, respectively. Feeding studies demonstrated that GK knockdown had no effect on food intake. GK knockdown in both the NTS and PVN impaired glucose tolerance and disrupted glucose-stimulated insulin secretion. PVN GK knockdown also reduced glucose-stimulated glucagon-like peptide 1 (GLP-1) release. On the other hand, up-regulating GK expression in the PVN had the opposite effect and improved glucose tolerance by stimulating insulin and GLP-1 release. These effects were reproduced by iPVN injection of KATP channel modulators during an oral GTT. Evidence presented in this thesis suggests that NTS and PVN GK play an important role in glucose homeostasis by regulating insulin and GLP-1 (7-36) secretion during the initial insulin response to hyperglycaemia. GK in both the NTS and PVN appears important in restoring euglycaemia following a glucose challenge. In the PVN, this seems to be mediated by the inhibition of KATP channels. This study sheds light on the previously unexplored function of GK in the NTS and PVN. A role of PVN and NTS GK in modulating insulin and GLP-1 (7-36) release in the regulation of glucose homeostasis has not been suggested before.

description: The present paper is meant as an update of the presentation given in a previous Resistive Plate Chamber (RPC) workshop, aimed at finding an eco-friendly gas mixture for streamer operation of RPCs. Indeed the streamer working regime is still suitable for building large RPC systems dedicated to low rate applications, such as cosmic ray and neutrino physics. In addition to other studies about gas mixtures for streamer mode operation, in this paper the replacement of R134a with CF4, a gas widely used in other gaseous detectors, has been investigated. The effect of the gas gap thickness on the discharge quenching has also been studied; this is an important check because thin gas gaps of 1 mm, one half of the typical used value, have been introduced for high rate applications. Finally preliminar results about the streamer formation timing are also reported.
The initial stellar mass function from random sampling in hierarchical clouds II: statistical fluctuations and a mass dependence for starbirth positions and times
Creators: name: Elmegreen, B. G.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Observed variations in the slope of the initial stellar mass function are shown to be consistent with a model in which the protostellar gas is randomly sampled from hierarchical clouds at a rate proportional to the square root of the local density. RMS variations in the IMF slope around the Salpeter value are +/- 0.4 when only 100 stars are observed, and +/- 0.1 when 1000 stars are observed. The hierarchical-sampling model also reproduces the tendency for massive stars to form closer to the center of a cloud, at a time somewhat later than the formation time of the lower mass stars. The assumed density dependence for the star formation rate is shown to be appropriate for turbulence compression, magnetic diffusion, gravitational collapse, and clump or wavepacket coalescence. The low mass flattening in the IMF comes from the inability of gas to form stars below the thermal Jeans mass at typical temperatures and pressures. Consideration of heating and cooling processes indicate why the thermal Jeans mass should be nearly constant in normal environments, and why it might increase in some starburst regions. The steep IMF in the extreme field is not explained by the model, but other origins are suggested.

Electromagnetic sensing of cell suspensions in microfluidic systems
Creators: name: Watts, Clare
Publisher: name: Imperial College London
Year: 2017

description: Cancer is one of the leading causes of death worldwide, and cancers which metastasise, the process of cancer spreading from one organ to another within the body, have the highest fatality rates. Although the mechanism of metastasis is not well understood, the study of cells in the circulatory system which are known to seed tumours is of great importance in cancer research. Current methods for detection of such cells, although specific and sensitive, result in their destruction, and have drawbacks associated with a bias towards specific cell markers. This work seeks to assess the feasibility of using dielectric spectroscopy and the variation in dielectric properties of different cells at microwave frequencies to characterise and separate circulating tumour cells (CTCs) and other abnormal cells from peripheral circulating blood. This technique is non-destructive and label free, and opens the door to a flow-cytometer system based purely on the physical properties of different cells, capable of measuring them in their natural state. A novel coupled-resonator sensor is introduced in this work, and used to make dielectric measurements of polystyrene microspheres as well as single, flowing, viable cells of three different types at ~10 GHz. The results have been compared to Raman spectroscopy analysis of the cultured cells, showing potential correlation between the water content of the cell types investigated, and the response of the novel system. This is of diagnostic value, with cell hydration linked to carcinogenesis.
Gravitational Lensing by Cold Dark Matter Catastrophes
Creators: name: Hogan, Craig J.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Intrinsically cold particle dark matter inevitably creates halos with sharp discontinuities in projected surface density caused by the projection of fold catastrophes onto the sky. In principle, these imperfections can be detected and measured with gravitational lensing through discontinuities in image magnification and image structure. Lens solutions are discussed for the most common universal classes of discontinuities. Edges caused by cold particles such as condensed axions and thermal WIMPs are very sharp, respectively about $10^{-12}$ and $10^{-7}$ of the halo scale. Their structure can be resolved by stellar and quasi-stellar sources which show sudden changes in brightness or even sudden disappearances (sometimes within hours) as edges are crossed. Images of extended objects such as edge-on galaxies or jets can show sudden bends at an edge, or stretched, parity-inverted reflection symmetry about a sharp line. Observational strategies and prospects are briefly discussed.

Deep component analysis: algorithms and applications
Creators: name: Trigeorgis, George
Publisher: name: Imperial College London
Year: 2017

description: Component Analysis (CA) methods have been crucial contributors for the large success of machine learning over the past decades. Although predominately all CA methods are linear models, depending on the formulation of the optimisation problem one can derive vastly different results tailored to different tasks. Such linear methods have the natural advantage of intepretability as they can easily be reasoned about, but also they are easy to fit onto the available data. Unfortunately, as they are mostly linear models they can not describe complex data distributions such as in-the-wild images of faces or, videos, or even auditory signals. On the other hand deep learning methodologies have excelled in modelling highly non-linear relations between highly heterogenious data distributions. Nonetheless, they were mostly used as black-boxes and usually required orders of magnitude more training samples than their linear counterparts to achieve similar performance. In this thesis we will aim to combine the best of both worlds. That is to incorporate the power of neural networks with the statistical intuition and the specially crafted ideas of component analysis methods. The result methodologies will have a diverse application set, solving problems from the areas of face clustering, timeseries alignment, domain adaptation, and face alignment in a mainly unsupervised way.
Parallel, hierarchical solution algorithms for diffusion synthetic Acceleration of the neutron transport equation
Creators: name: O'Malley, Benedict John
Publisher: name: Imperial College London
Year: 2017

description: The ability to obtain fast and accurate solutions of the neutron transport equation is of great importance for various reactor physics and radiation shielding applications. This thesis first presents an overview of the techniques used to solve the neutron transport equation using discontinuous Galerkin finite element methods. It then presents two sets of techniques which aim to improve the effectiveness of a neutron transport code and provides various computational results to support their effectiveness. The first methods studied are two preconditioners designed to accelerate the solution of the neutron diffusion equation which in turn is used to accelerate the neutron transport equation using diffusion synthetic acceleration. They are first presented in a form appropriate for solving finite element problems using first-order basis functions, and then expanded so that they may be used on problems containing second and higher-order basis functions. The second study is for sets of basis functions for pyramid finite elements used in the solution of neutron transport and neutron diffusion problems, demonstrating the effectiveness of these elements in comparison to other element types. This thesis provides substantial evidence for the effectiveness of the methods described alongside an analysis of where their use is appropriate. Numerous computational examples are used, including several reactor physics and radiation shielding benchmark problems obtained from benchmark specifications. These serve to demonstrate the strengths and in some cases the weaknesses of the techniques presented. The methods presented have significant practical applications in the fields of reactor physics and radiation shielding.

description: This study explores the space density and properties of active galaxies to z=0.8. We have investigated the frequency and nature of unresolved nuclei in galaxies at moderate redshift as indicators of nuclear activity such as Active Galactic Nuclei (AGN) or starbursts. Candidates are selected by fitting imaged galaxies with multi-component models using maximum likelihood estimate techniques to determine the best model fit. We select those galaxies requiring an unresolved, point source component in the galaxy nucleus, in addition to a disk and/or bulge component, to adequately model the galaxy light. We have searched 70 WFPC2 images primarily from the Medium Deep Survey for galaxies containing compact nuclei. In our survey of 1033 galaxies, the fraction containing an unresolved nuclear component greater than 3% of the total galaxy light is 16+/-3% corrected for incompleteness and 9+/-1% for nuclei greater than 5% of the galaxy light. Spectroscopic redshifts have been obtained for 35 of our AGN/starburst candidates and photometric redshifts are estimated to an accuracy of sigma_z=0.1 for the remaining sample. In this paper, the first of two in this series, we present the selected HST imaged galaxies having unresolved nuclei and discuss the selection procedure. We also present the ground-based spectroscopy for these galaxies as well as the photometric redshifts estimated for those galaxies without spectra.

Evolution of hydrothermal alteration facies at the Cerro Corona Cu-Au porphyry deposit, Northern Peru
Creators: name: Longridge, Jacob
Publisher: name: Imperial College London
Year: 2016

description: The Cerro Corona deposit is an active copper gold porphyry deposit, located in the Hualgayoc District, Northern Peru. Its magmatic evolution is conformable with the current regional model of crustal thickening, flat slab subduction and uplift. The deposit comprises of multiple mineralogically and chemically indistinguishable biotite quartz diorite porphyry intrusions, followed by intrusions of hornblende granodiorite and andesite dykes. Igneous amphibole chemistry of these later intrusions suggests an increasing input of deeper, mafic hydrous melts into a shallower magma chamber, similar to the paragenesis at the nearby Yanacocha district. Hydrothermal alteration is similar to other porphyry-type deposits, however the argillic alteration telescopes onto the entire deposit, with pervasive argillic alteration extending to a depth of 400m from the current surface. This suggests a significant uplift during hydrothermal alteration. Error is propagated through the mass transfer calculations, allowing for a more confident interpretation of mass transfer models. These models show large net transfer of major and minor components during potassic, propylitic and sericitic alteration, but less drastic changes during argillic alteration. A 3D net mass transfer models is done for the first time on a porphyry deposit, which reveals a previously unidentified zone of potassic alteration in the north. Infrared spectroscopy revealed the dominant clay mineral is smectite, with mixture of illite- and/or kaolinite. Kaolinite-dominant argillic alteration appears to be related to sulphide oxidation near the surface and telescopes down along preferentially permeable zones, whereas smectite-dominant argillic alteration occurs at near neutral conditions, deeper and peripheral to zones of sulphide mineralisation. Intracrystalline oxygen isotope fractionation indicates illite formed at temperatures of ~300°C and kaolinite >150°C. The calculated fluid compositions suggests illite-formation fluids are composed of >70% magmatic-derived fluids; kaolinite-formational fluids being an equal mix of meteoric and magmatic fluids and smectite-formational fluid being predominantly heated meteoric fluid.

description: Deep learning has enabled traditional reinforcement learning methods to deal with high-dimensional problems. However, one of the disadvantages of deep reinforcement learning methods is the limited exploration capacity of learning agents. In this paper, we introduce an approach that integrates human strategies to increase the exploration capacity of multiple deep reinforcement learning agents. We also report the development of our own multi-agent environment called Multiple Tank Defence to simulate the proposed approach. The results show the significant performance improvement of multiple agents that have learned cooperatively with human strategies. This implies that there is a critical need for human intellect teamed with machines to solve complex problems. In addition, the success of this simulation indicates that our multi-agent environment can be used as a testbed platform to develop and validate other multi-agent control algorithms.

description: This study focuses on the implementation of modern and intelligent logistics vehicles equipped with advanced tracking and security features. In response to the evolving landscape of logistics management, the proposed system integrates cutting edge technologies to enhance efficiency and ensure the security of the entire logistics process. The core component of this implementation is the incorporation of state-of-the art tracking mechanisms, enabling real-time monitoring of vehicle locations and movements. Furthermore, the system addresses the paramount concern of security by introducing advanced security measures. Through the utilization of sophisticated tracking technologies and security protocols, the proposed logistics vehicles aim to safeguard both customer and provider data. The implementation includes the integration of QR code concepts, creating a binary image system that conceals sensitive information and ensures access only to authorized users. In addition to tracking and security, the study delves into the realm of information mining, employing techniques such as classification, clustering, and recommendation to extract meaningful patterns from vast datasets. Collaborative filtering techniques are incorporated to enhance customer experience by recommending services based on user preferences and historical data. This abstract encapsulates the comprehensive approach of deploying modern logistics vehicles, emphasizing their intelligence through advanced tracking, robust security measures, and data-driven insights. The proposed system aims to revolutionize logistics management, providing a seamless and secure experience for both customers and service providers in the dynamic logistics landscape.

In this second of two papers in this series, we discuss the nature of the compact nuclei and their hosts. We present the upper limit luminosity function (LF) for low-luminosity AGN (LLAGN) in two redshift bins to z=0.8. Mild number density evolution is detected for nuclei at -18 < M_B < -14. The LFs appear to flatten at M_B > -16 and this flatness, combined with the increase in number density, is inconsistent with pure luminosity evolution. Based on the amount of density evolution observed for these objects, we find that almost all present-day spiral galaxies could have hosted a LLAGN at some point in their lives. We also comment on the likely contribution of these compact nuclei to the soft X-ray background.

Infinite-dimensional linear programming and model-independent hedging of contingent claims
Creators: name: Badikov, Sergey
Publisher: name: Imperial College London
Year: 2017

description: We consider model-independent pathwise hedging of contingent claims in discrete-time markets, in the framework of infinite-dimensional linear programmes (LP). The dual problem can be formulated as optimization over the set of martingale measures subject to market constraints. Absence of model-independent arbitrage plays a crucial role in ensuring that both the primal and the dual problems are well posed and there is no duality gap. In fact we show that different notions of model-independent arbitrage are required to prove duality results in various settings. We then specialize this duality theory to the situation where European Call options are traded on the market. In particular we consider hedging portfolios that consist of static positions in traded options and a dynamic trading strategy. The dual variables are then constrained to martingale measures consistent with prices of traded options. When only finitely many Call options are traded, the notion of weak arbitrage introduced in Davis and Hobson (2007) is sufficient to ensure absence of duality gap between the primal and the dual problems. In this case the set of feasible dual variables is not closed, and extrapolation of Call option prices (equivalently of the implied volatility smile) is required. We finally provide numerical examples to support our theoretical claims. By discretizing the infinite-dimensional LPs, we compute arbitrage-free price bounds for Forward-Start options. We further perform a sensitivity analysis of the aforementioned extrapolation and find that in the case of Forward- Start options it does not significantly influence arbitrage bounds obtained by numerically solving discretized problems.

description: Time domain interferometry is a promising method to characterizes spatial and temporal correlations at x-ray energies, via the so-called intermediate scattering function and the related dynamical couple correlations. However, so far, it has only been analyzed for classical target systems. Here, we provide a quantum analysis, and suggest a scheme which allows to access quantum dynamical correlations. We further show how TDI can be used to exclude classical models for the target dynamics, and illustrate our results using a single particle in a double well potential.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: In this article we have studied the transverse momentum distribution of the pseudo-scalar Higgs boson at the Large Hadron Collider (LHC). The small $\pt$ region which provides the bulk of the cross section is not accessible to fixed order perturbation theory due to the presence of large logarithms in the series. Using the universal infrared behaviour of the QCD we resum these large logarithms up to next-to-next-to-leading logarithmic (NNLL) accuracy. We observe a significant reduction in theoretical uncertainties due to the unphysical scales at NNLL level compared to the previous order. We present the $p_T$ distribution matched to NNLO$_A$+NNLL, valid for the whole $p_T$ region and provide a detailed phenomenological study in the context of both 14 TeV and 13 TeV LHC using different choices of masses, scales and parton distribution functions which will be useful for the search of such particle at the LHC in near future.

This leads to the profile broadening and polarization dependence on the wavelength shift as a function of the Thomson optical depth $τ_T$. We find that the polarization of the Thomson-scattered emission lines has a dip around the line center when $τ_T$ does not exceed a few. Various structures such as the polarization flip are also seen. An application to an ionized halo component surrounding the broad emission line region in active galactic nuclei is considered and it is found that the polarization structures may still persist. Brief discussions on observational implications are given.

description: Collective transport through channels shows surprising properties under one-dimensional confinement: particles in a single file exhibit sub-diffusive behavior, while liquid confinement causes distance-independent correlations between the particles. Such interactions in channels are well studied for passive Brownian motion, but driven transport remains largely unexplored. Here, we demonstrate gating of transport due to a speed-up effect for actively driven particle transport through microfluidic channels. We prove that particle velocity increases with particle density in the channel due to hydrodynamic interactions under electrophoretic and gravitational forces. Numerical models demonstrate that the observed speed-up of transport originates from a hydrodynamic piston-like effect. Our discovery is fundamentally important for understanding protein channels and transport through porous materials and for designing novel sensors and filters.

description: We report the most sensitive search yet made for solar-like oscillations. We observed the star alpha Cen A in Balmer-line equivalent widths over six nights with both the 3.9m Anglo-Australian Telescope and the ESO 3.6m telescope. We set an upper limit on oscillations of 1.4 times solar and found tentative evidence for p-mode oscillations. We also found a power excess at low frequencies which has the same slope and strength as the power seen from granulation in the Sun. We therefore suggest that we have made the first detection of temporal fluctuations due to granulation in a solar-like star.

The geometry of second-order statistics - biases in common estimators
Creators: name: Kerscher, Martin
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Second-order measures, such as the two-point correlation function, are geometrical quantities describing the clustering properties of a point distribution. In this article well-known estimators for the correlation integral are reviewed and their relation to geometrical estimators for the two-point correlation function is put forward. Simulations illustrate the range of applicability of these estimators. The interpretation of the two-point correlation function as the excess of clustering with respect to Poisson distributed points has led to biases in common estimators. Comparing with the approximately unbiased geometrical estimators, we show how biases enter the estimators introduced by Davis and Peebles, Landy and Szalay, and Hamilton. We give recommendations for the application of the estimators, including details of the numerical implementation. The properties of the estimators of the correlation integral are illustrated in an application to a sample of IRAS galaxies. It is found that, due to the limitations of current galaxy catalogues in number and depth, no reliable determination of the correlation integral on large scales is possible. In the sample of IRAS galaxies considered, several estimators using different finite-size corrections yield different results on scales larger than 20 Mpc/h, while all of them agree on smaller scales.

Symmetry and degeneracy in nonconvex optimisation problems: Application to heat recovery networks
Creators: name: Kouyialis, Georgia
Publisher: name: Imperial College London
Year: 2018

description: Many optimisation problems are formulated with nonconvexities in the objective function and the set of constraints. Nonconvex optimisation has applications in a wide range of disciplines and this thesis examines scheduling and process network design problems. Two main solution approaches are used to deal with such problems: exact and approximation algorithms. Exact algorithms guarantee to solve a problem to global optimality but may require exponential time. On the other hand, approximation algorithms can generate near-optimal solutions in reasonable time. Both sets of algorithms could benefit from insights on the special structure of optimisation problems, e.g. symmetry and degeneracy. This thesis proposes novel structures i.e. matrices and graphs, for detecting symmetry in Quadratically Constrained Quadratic Programs. In several critically important engineering applications, such as Heat Exchanger Network Synthesis (HENS), symmetry and degeneracy have not been characterised yet. This work investigates the minimum number of matches, e.g. heat exchanger units, which is the current bottleneck in designing HENS. We classify special cases with many equivalent optimal solutions and define symmetry and degeneracy. Due to the aforementioned complexities, we report via computational results that state-of-the-art approaches cannot solve the minimum number of matches problem to global optimality for moderately-sized instances. Hence this thesis develops three classes of heuristics with performance guarantees to the minimum number of matches problem. Each of these heuristics is either novel or provably the best in its class. Our work has interesting implications for solving the problem exactly, e.g. the analysis into reducing big-M parameters or the possibility of quickly generating good primal feasible solutions. Detecting special structures in optimisation problems and dealing with instances of HENS is neither trivial nor easy. This thesis provides an in-depth analysis of these problems and develops fundamental tools to efficiently solve challenging optimisation problems via both exact and approximation approaches.

description: We present a procedure for assessing the urban exposure and seismic vulnerability that integrates LiDAR data with aerial and satellite images. It comprises three phases: first, we segment the satellite image to divide the study area into different urban patterns. Second, we extract building footprints and attributes that represent the type of building of each urban pattern. Finally, we assign the seismic vulnerability to each building using different machine-learning techniques: Decision trees, SVM, logistic regression and Bayesian networks. We apply the procedure to 826 buildings in the city of Lorca (SE Spain), where we count on a vulnerability database that we use as ground truth for the validation of results. The outcomes show that the machine learning techniques have similar performance, yielding vulnerability classification results with an accuracy of 77% - 80% (F1-Score). The procedure is scalable and can be replicated in different areas. It is especially interesting as a complement to conventional data gathering approaches for disaster risk applications in areas where field surveys need to be restricted to certain areas, dates or budget. Keywords LiDAR, satellite image, orthophoto, image segmentation, machine learning, earthquake vulnerability.
The origin of carbon, investigated by spectral analysis of solar-type stars in the Galactic Disk

description: Abundance analysis of carbon has been performed in a sample of 80 late F and early G type dwarf stars in the metallicity range -1.06 < [Fe/H] < 0.26 using the forbidden [C I] line at 8727 A. This line is presumably less sensitive to temperature, atmospheric structure and departures from LTE than alternative carbon criteria. We find that [C/Fe] decreases slowly with increasing [Fe/H] with an overall slope of -0.17 +- 0.03. Our results are consistent with carbon enrichment by superwinds of metal-rich massive stars but inconsistent with a main origin of carbon in low-mass stars. This follows in particular from a comparison between the relation of [C/O] with metallicity for the Galactic stars and the corresponding relation observed for dwarf irregular galaxies. The significance of intermediate-mass stars for the production of carbon in the Galaxy is still somewhat unclear.
