Cosmic Infrared Background and Early Galaxy Evolution

description: The Cosmic Infrared Background (CIB) reflects the sum total of galactic luminosities integrated over the entire age of the universe. From its measurements one can deduce information about objects at epochs currently inaccessible to telescopic studies. This review discusses the state of the current CIB measurements and the (mostly space-based) instruments with which these measurements have been made, the obstacles (the various foreground emissions)and the physics behind the CIB and its structure. Theoretical discussion of the CIB levels can now be normalized to the standard cosmological model narrowing down theoretical uncertainties. We review the information behind and theoretical modeling of both the mean (isotropic) levels of the CIB and their fluctuations. The CIB is divided into three broad bands: near-IR, mid-IR and far-IR. For each of the bands we review the main contributors to the CIB flux and the epochs at which the bulk of the flux originates. We also discuss the data on the various quantities relevant for correct interpretation of the CIB levels: the star-formation history, the present-day luminosity function measurements, resolving the various galaxy contributors to the CIB, etc. The integrated light of all galaxies in the deepest near-IR galaxy counts to date fails to match the observed mean level of the CIB, probably indicating a significant high-redshift contribution to the CIB. Additionally, Population III stars should have left a strong and measurable signature via their contribution to the cosmic infrared background (CIB) anisotropies for a wide range of their formation scenarios, and measuring the excess CIB anisotropies coming from high z would provide direct information on that epoch.

description: We combined scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS) experiments with density functional theory (DFT) calculations to study dispersed tungsta clusters on anatase TiO$_2$(101). Following two different preparation methods, we found that monomeric WO$_3$ species are the most stable configuration rather than WO$_3$ trimers, (WO$_3$)$_3$. The WO$_3$ monomers form tetrahedral WO$_4$ structures on anatase TiO$_2$(101), with one W$-$O bond and two W$-$O$-$Ti linkages per WO$_3$ monomer. Locally, the WO$_3$ monomers form well-ordered (2$\times$1) structures. The discovered geometric structure of WO$_3$ on anatase TiO$_2$(101) opens up numerous opportunities for fundamental studies addressing tungsta and accurate structure activity studies of WO$_3$/TiO$_2$ model catalysts.

A Note on T-duality in Heterotic String Theory

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We revisit the T-duality transformation rules in heterotic string theory, pointing out that the chiral structure of the world-sheet leads to a modification of the standard Buscher's transformation rules. The simplest instance of such modifications arises for toroidal compactifications, which are rederived by analyzing a bosonized version of the heterotic world-sheet Lagrangian. Our study indicates that the usual heterotic toroidal T-duality rules naively extended to the curved case cannot be correct, leading in particular to an incorrect Bianchi identity for the field strength H of the Kalb-Ramond field B. We explicitly show this problem and provide a specific example of dual models where we are able to get new T-duality rules which, contrary to the standard ones, lead to a correct T-dual Bianchi identity for H to all orders in α'.

description: In the present work we found the geodesic structure of an AdS black hole. By means of a detailed analyze of the corresponding effective potentials for particles and photon, we found all the possible motions which are allowed by the energy levels. Radial and non radial trajectories were exactly evaluated for both geodesics. The founded orbits were plotted in order to have a direct visualization of the allowed motions. We show that the geodesic structure of this black hole presents new type of motions not allowed by the Schwarzschild spacetime.

Simultaneous topology and fastener layout optimization of assemblies considering joint failure

Publisher: name: arXiv
Year: 2020
Subjects: subject: Computational Engineering, Finance, and Science (cs.CE)
subject: FOS: Computer and information sciences

description: This paper provides a method for the simultaneous topology optimization of parts and their corresponding joint locations in an assembly. Therein, the joint locations are not discrete and predefined, but continuously movable. The underlying coupling equations allow for connecting dissimilar meshes and avoid the need for remeshing when joint locations change. The presented method models the force transfer at a joint location not only by using single spring elements but accounts for the size and type of the joints. When considering riveted or bolted joints, the local part geometry at the joint location consists of holes that are surrounded by material. For spot welds, the joint locations are filled with material and may be smaller than for bolts. The presented method incorporates these material and clearance zones into the simultaneously running topology optimization of the parts. Furthermore, failure of joints may be taken into account at the optimization stage, yielding assemblies connected in a fail-safe manner.

Understanding the effects of glucagon and bile acids on metabolism
Creators: name: McGlone, Emma Rose
Publisher: name: Imperial College London
Year: 2019

description: Obesity and related diseases of type 2 diabetes mellitus and non-alcoholic fatty liver disease are highly prevalent and responsible for a huge burden of morbidity and mortality. Better understanding of the signalling properties of endogenous metabolic mediators is key to the development of new drugs to treat these conditions. Bile acids and glucagon both regulate post-prandial metabolism, with diverse effects on many tissues and organ systems. Bile acids stimulate gut hormone secretion from the gut and have direct effects on hepatic and peripheral glucose and lipid processing. Glucagon has a particular role in the liver, where it increases endogenous glucose production and decreases lipid storage. In this thesis I firstly investigated the acute effect of two species of bile acid, ursodeoxycholic acid and chenodeoxycholic acid, on glucose homeostasis and circulating hormone levels after a meal. Both bile acids increased secretion of the anorectic hormones glucagon-like peptide 1 and peptide tyrosine tyrosine. This was associated with an increase in indices of insulin sensitivity. These findings suggest that manipulation of circulating bile acid levels during a meal could be helpful for the treatment of obesity and related diseases. Secondly, I studied the effect of an allosteric protein, Receptor Activity Modifying Protein 2 (RAMP2) on signalling of the glucagon receptor (GCGR). In human hepatocytes, RAMP2 decreases surface expression of GCGR, and this is associated with an increase in responsiveness to glucagon stimulation. These findings were not translated to differences in glucagon responsiveness in a mouse model of hepatic RAMP2 upregulation. Further experiments in mouse hepatoma cells suggest that this discrepancy may be due to a species difference in activity of the GCGR and RAMP2 orthologs. This body of work improves our understanding of GCGR physiology and is relevant to the development of drugs that target the receptor.

description: A major obstacle in radar based methods for concealed object detection on humans and seamless integration into security and access control system is the difficulty in collecting high quality radar signal data. Generative adversarial networks (GAN) have shown promise in data generation application in the fields of image and audio processing. As such, this paper proposes the design of a GAN for application in radar signal generation. Data collected using the Finite-Difference Time-Domain (FDTD) method on three concealed object classes (no object, large object, and small object) were used as training data to train a GAN to generate radar signal samples for each class. The proposed GAN generated radar signal data which was indistinguishable from the training data by qualitative human observers.

description: The indirect effects of ethanol on land are a focus of recent US biofuel literature and policy. The experiments presented here highlight the sensitivity of land use changes to assumptions about the ability of land to be converted from one use to another and the ease with which decision makers can make these conversions. By varying parameters governing land use in a simulation model, indirect effects on land use can be varied no less widely. Extending this result, there is an inverse relationship between the responsiveness of land allocation, which is a key element of overall supply response in the medium-term, and the magnitude of price effects: for a given shock, greater land response dampens the scale of price changes and lower land response is associated with greater price effects. Moving beyond agricultural commodity markets alone, Brazilian ethanol markets may be as sensitive to prices as US markets are sometimes believed to be. If so, then changes in Brazilian trade may represent a substantial part of the market response to changes in US ethanol consumption at least over certain ranges. With uncertainties about area and ethanol market effects taken into account, a particular path of US imports may be associated with any number of land use effects.

description: Swift J0243.6+6124 was discovered during a giant X-ray outburst in October 2017. While there are numerous studies in the X-ray band, very little is known about the optical counterpart. We have performed an spectral and photometric analysis of the optical counterpart of this intriguing source. We find that the optical counterpart to Swift J0243.6+6124 is a V = 12.9, O9.5Ve star, located at a distance of $\sim5$ kpc. The optical extinction in the direction of the source is $A_V=3.6$ mag. The rotational velocity of the O-type star is 210 km s$^{-1}$. The long-term optical variability agrees with the growth and subsequent dissipation of the Be circumstellar disk after the giant X-ray outburst. The optical and X-ray luminosity are strongly correlated during the outburst, suggesting a common origin. We did not detect short-term periodic variability that could be associated with nonradial pulsations from the Be star photosphere.

description: We report the discovery in the Galactic Centre region of two hard X-ray sources, designated as XMM J174457-2850.3 and XMM J174544-2913.0, which exhibited flux variations in the 2--10 keV band in excess of a factor of 100 in observations spanning roughly a year. In both cases the observed hydrogen column density is consistent with a location near to the Galactic Centre, implying peak X-ray luminosities of ~5 x 10^34 erg/s. These objects may represent a new population of transient source with very different properties to the much more luminous Galactic Centre transients associated with neutron star and black-hole binary systems. Spectral analysis shows that XMM J174457-2850.3 has relatively weak iron-line emission set against a very hard continuum. XMM J174544-2913.0, on the other hand, has an extremely strong K-line from helium-like iron with an equivalent width of ~2.4keV. The nature of the latter source is of particular interest. Does it represent an entirely new class of object or does it correspond to a known class of source in a very extreme configuration?

description: In 1993, the Sasakawa/Global 2000 Program (SG) and the Ministry of Agriculture (MOA) began a joint program to demonstrate that substantial productivity increases could be achieved when farmers were given appropriate extension messages and agricultural inputs were delivered on time at reasonable prices. The program provided credit, inputs and extension assistance to participants willing to establish half-hectare demonstration plots on their own land. In 1995, the MOA/SG demonstration program reached more than 3,500 farmers. During the same year MOA launched the New Extension Program (NEP) based on SG principles but managed independently. By 1997, NEP was managing the bulk of the demonstration plots. Although the MOA/SG program is widely considered to be a success, no formal analysis had been carried out to determine its profitability. In September 1997 MOA/SG agreed to collaborate with MSU to answer the following questions: (1) Is improved technology financially profitable for farmers? (2) Is it economically profitable from a national perspective? (3) What factors limit crop response to improved technologies? and (4) What challenges does the government face as it scales up the NEP program?

description: We discuss the backreaction force exerted by quantum fluctuations in dilute Bose-Einstein condensates onto the motion of the classical background, derived by an ab initio approach from microscopic physics. It is shown that the effective-action method, widely employed in semiclassical quantum gravity, fails to give the full backreaction force. The failure of the effective-action method is traced back, inter alia, to the problem of the correct choice of the fundamental variables and the related operator ordering issues.

Ground motion selection for generalised conditional intensity measure targets and the target construction
Creators: name: Shi, Yuan
Publisher: name: Imperial College London
Year: 2019

description: A record selection algorithm aims to select a set of ground motion records whose statistics match a target distribution which is consistent with seismological properties of interest for a given site. Thus, the selected records are implicitly consistent with the seismological properties of interest and the subsequent estimations of responses are decided by the seismological properties of interest. This thesis addresses several issues related to ground motion selection in terms of selection algorithms and the definition and construction of target distributions. Two new algorithms for efficiently selecting suites of ground motions that match a Generalized Conditional Intensity Measure (GCIM) target are firstly generated. These algorithms utilize advance sampling methods which allows for a high chance of generating samples consistent with a target continuous distribution and/or allows for additional constrains are priorities for some important properties of interest. A new algorithm for efficiently selecting a suite of records matching to multiple targets as closely as possible is then developed. This algorithm is able to be adopted in the Incremental Dynamic Analysis to reduce biases to a minimum level when there are the significant changes in terms of the distribution of causal parameters among different intensity measure levels. The investigation is subsequently conducted for whether all features of interest for a give site can be well represented by the use of one target distribution constructed following the “Exact” Conditional Spectrum (CS) approach which is commonly regarded as an exact approach within the community. A framework to establish a CS-based target with the goal of accounting for spectral accelerations at multiple damping ratios is finally introduced.

description: In this paper, we propose a novel framework for the smart healthcare system, where we employ the compressed sensing (CS) and the combination of the state-of-the-art machine learning based denoiser as well as the alternating direction of method of multipliers (ADMM) structure. This integration significantly simplifies the software implementation for the lowcomplexity encoder, thanks to the modular structure of ADMM. Furthermore, we focus on detecting fall down actions from image streams. Thus, teh primary purpose of thus study is to reconstruct the image as visibly clear as possible and hence it helps the detection step at the trained classifier. For this efficient smart health monitoring framework, we employ the trained binary convolutional neural network (CNN) classifier for the fall-action classifier, because this scheme is a part of surveillance scenario. In this scenario, we deal with the fallimages, thus, we compress, transmit and reconstruct the fallimages. Experimental results demonstrate the impacts of network parameters and the significant performance gain of the proposal compared to traditional methods.

description: We use discrete-event simulation on a digital computer to study two different models of experimentally realizable quantum walks. The simulation models comply with Einstein locality, are as "realistic" as the one of the simple random walk in that the particles follow well-defined trajectories, are void of concepts such as particle-wave duality and wave-function collapse, and reproduce the quantum-theoretical results by means of a cause-and-effect, event-by-event process. Our simulation model for the quantum walk experiment presented in [C. Robens et al., Phys. Rev. X 5, 011003 (2015)] reproduces the result of that experiment. Therefore, the claim that the result of the experiment "rigorously excludes (i.e., falsifies) any explanation of quantum transport based on classical, well-defined trajectories" needs to be revised.

description: El presente es un estudio de caso de la aglomeración productiva generada a raíz de la puesta en marcha del proyecto minero Yanacocha, ubicado en Cajamarca. El concepto de aglomeración o cluster industrial se basa sobre el supuesto de que las distintas actividades económicas no se desarrollan aisladamente, sino que, por el contrario el crecimiento de una de ellas impulsa el de actividades conexas. El análisis del cluster articulado alrededor de la empresa Minera Yanacocha S.A. revela que, debido a una serie de cuellos de botella en los ámbitos tecnológicos e institucional de Cajamarca, la transmisión de crecimiento económico generado por esta empresa hacia otros agentes locales es aún limitado. Minera Yanacocha S.A. mantiene escasaz relaciones productivas y comerciales con los agentes cajamarquinos, mientras que establece una mayor articulación con agentes productivos e institucionales limeños y con instituciones públicas y gremiales de la capital. Aún cuando las relaciones productivas se dan principalmente con empresas limeñas, la debilidad tecnológica de las mismas las limita a un rol comercializador. Sin embargo, las empresas cajamarquinas tienen una ventaja competitiva en la provisión de servicios no intensivos en conocimiento. Estos resultados resaltan la necesidad de políticas públicas que, por un lado, mejoran la infraestructura productiva y tecnológica cajamarquina, así como que coadyuven a elevar la capacidad de absorción tecnológica de las empresas de la zona; y por otro lado, que induzcan el establecimiento de productores nacionales de bienes, insumos y equipos mineros.

description: We present a 21cm line HI self-absorption (HISA) survey of cold atomic gas within Galactic longitudes 75 to 146 degrees and latitudes -3 to +5 degrees. We identify HISA as spatially and spectrally confined dark HI features and extract it from the surrounding HI emission in the arcminute-resolution Canadian Galactic Plane Survey (CGPS). We compile a catalog of the most significant features in our survey and compare our detections against those in the literature. Within the parameters of our search, we find nearly all previously detected features and identify many new ones. The CGPS shows HISA in much greater detail than any prior survey and allows both new and previously-discovered features to be placed into the larger context of Galactic structure. In space and radial velocity, faint HISA is detected virtually everywhere that the HI emission background is sufficiently bright. This ambient HISA population may arise from small turbulent fluctuations of temperature and velocity in the neutral interstellar medium. By contrast, stronger HISA is organized into discrete complexes, many of which follow a longitude-velocity distribution that suggests they have been made visible by the velocity reversal of the Perseus arm's spiral density wave. The cold HI revealed in this way may have recently passed through the spiral shock and be on its way to forming molecules and, eventually, new stars. This paper is the second in a series examining HISA at high angular resolution. A companion paper (Paper III) describes our HISA search and extraction algorithms in detail.

description: On the 27th of November 2015, at 10:43:45.526 UTC, a fireball was observed across South Australia by ten Desert Fireball Network observatories lasting 6.1 s. A $\sim37$ kg meteoroid entered the atmosphere with a speed of 13.68$\pm0.09\,\mbox{km s}^{-1}$ and was observed ablating from a height of 85 km down to 18 km, having slowed to 3.28$\pm0.21 \,\mbox{km s}^{-1}$. Despite the relatively steep 68.5$^\circ$ trajectory, strong atmospheric winds significantly influenced the darkfight phase and the predicted fall line, but the analysis put the fall site in the centre of Kati Thanda - Lake Eyre South. Kati Thanda has metres-deep mud under its salt-encrusted surface. Reconnaissance of the area where the meteorite landed from a low flying aircraft revealed a 60 cm circular feature in the muddy lake, less than 50 m from the predicted fall line. After a short search, which again employed light aircraft, the meteorite was recovered on the 31st December 2015 from a depth of 42 cm. Murrili is the first recovered observed fall by the digital Desert Fireball Network (DFN). In addition to its scientific value, connecting composition to solar system context via orbital data, the recover demonstrates and validates the capabilities of the DFN, with its next generation remote observatories and automated data reduction pipeline.

description: We discuss the results of the calculation of the photoionization with de-excitation of excited He and helium-like ions Li$^{+}$ and B$^{3+}$ at high but non-relativistic photon energies $ω$. Several lower $^{1}S$ and $^{3}S$ states are considered. We present and analyze the ratios $R_{d}^{+\ast}$ of the cross sections of photoionization with de-excitation, $σ_{(d)}^{+\ast}(ω)$, and of the photo-ionization with excitation, $σ^{+\ast}(ω)$. The dependence of $R_{d}^{+\ast}$ on the excitation of the target object and the charge of its nucleus is presented. Apart to theoretical interest, results obtained can be verified using such long living excited state as $2^{3}S$ of He.

Aromatic metamorphosis: the intramolecular Diels-Alder reaction
Creators: name: Shute, Jonathan
Publisher: name: Imperial College London
Year: 2019

description: This thesis details investigations into new Diels-Alder reactions primarily for the synthesis of pyridines, annulated pyridine derivatives (2,7-naphthyridin-1(2H)-ones), and oxidised pyridine derivatives (isoquinolin-1(2H)-ones). New methods for synthesis of highly substituted pyridines are in high demand because of their diverse pharmaceutical applications. In Chapter 2, investigations towards the synthesis of highly substituted pyridines involved a proposed ene-Diels-Alder cascade cyclisation. An oxazole dialkyne substrate was produced in a multistep synthesis involving early stage utilisation of the oxazole unit followed by novel metalation and allylation of the oxazole, hydroboration-oxidation, acetylide addition, protection and finally propargylation. Furan containing precursors were additionally synthesised and these were expected to undergo a related ene-Diels-Alder mechanism. However, cyclisation of this precursor led unexpectedly to the formation of a novel Diels-Alder adduct. In Chapter 3, a lithium iodide mediated intramolecular Diels-Alder reaction has been developed for the synthesis of substituted isoquinolones from both pyrrole and furan containing precursors (Scheme 2). In situ allene formation has been postulated to explain the formation of "abnormal" Diels-Alder adducts, and these could be synthesised in yields of 50–60%, despite their instability to fragmentation with prolonged heating to form isoquinolones. Molecules containing isoquinolone motifs are of interest because of their biological significance and their potential applications as medicinal drugs. Extension of the methodology to precursors containing oxazoles enabled the formation of annulated pyridines, and complementary conditions for the formation of annulated furans and pyridines were discovered. In conditions of an inert solvent (TCE), furans were exclusively synthesised via elimination of a nitrile component. Lithium iodide / pyridine conditions were utilised to override this inherent reactivity, and pyridines could be synthesised with both aliphatic and aromatic substituents. With an aromatic group in the 4-position, selectivity of the pyridine over the furan fragmentation products was especially high. The work in chapters 3 and 4 has been included in a patent application, which has been filed, application number 1815763.6 (I provided much of the data for the patent, I influenced the angle of the patent and the writing of the claims. My creative input was involved e.g. in proposing the direction of oxazoles to form pyridines.)

Studies toward the chemistry of N-confused porphyrins
Creators: name: Xiao, Ziwei
Publisher: name: University of British Columbia
Year: 2009

description: The objectives of this work were to study the chemistry of N-confused porphyrins, which is a porphyrin isomer with an inverted pyrrole ring, and to develop new photosensitizers based on N-confused porphyrins for photodynamic therapy (PDT). Alkylation reactions of N-confused porphyrins were studied. N-confused tetraarylporphyrins reacted with CH₃ I in the presence of Na₂C0₃ to yield N,N'-dimethylated N - confused porphyrin salts 103 - 107, which are mixtures of structural isomers. The structures of the major isomers (III) were determined by X-ray diffraction and NMR spectroscopic analyses. These N,N'-dimethylated N-confused tetraarylporphyrin salts can generate singlet oxygen when irradiated with light of the appropriate wavelengths and are potential photosensitizers for PDT. The peripheral carbon-nitrogen double bonds of Ni(II) N-confused porphyrins are partially isolated from the 18 π conjugated aromatic system and reacted as dienophiles in Diels- Alder reactions with o-benzoquinodimethane yielding novel Ni(II) N-confused isoquinoporphyrins 133 (a-c). Ni(II) N-confused tetraphenylisoquinoporphyrin, 133a, was structurally characterized by X-ray diffraction analysis. Reaction of Ni(II) N-confused tetrakis(p-tolyl)porphyrin with NaOCH₃ and DDQ resulted in the inner C(21) cyanide addition product 146. Minor product 145 was presumably formed by subsequent nucleophilic addition of CH₃O⁻ to 146 at C(3) followed by oxidation with DDQ. Structures of both complexes 145 and 146 were determined by X-ray diffraction analyses. The Ni(III) complex of N-confused porphyrin inner C-oxide 153 was synthesized from oxidation of the precursor Ni(II) N-confused porphyrin using OSO₄. This Ni(III) complex has been structurally characterized.

description: We claim that crystal field (CEF) levels exist in UPd2Al3 in contrary to a recent claim of Hiess et al. (cond-mat/0411041) and Bernhoeft et al. (cond-mat/0411042), that there is no experimental evidence for discrete crystal field levels in this superconducting heavy-fermion antiferromagnet. We claim that excitations revealed by Krimmel et al. (J. Phys.: Condens. Matter 8 (1996) 1677 in inelastic-neutron-scattering (INS) studies are i) crystal-field excitations described by us within ii) the 5f3 (U3+) configuration. Moreover, our 5f3 (U3+) scheme, presented in Physica B 276-278 (2000) 803 and in Czech. J. Phys. 54 (2004) D295, provides a clear physical explanation for the 1.7 meV excitation (magnetic exciton) as associated to the removal of the Kramers-doublet ground state degeneracy in the antiferromagnetic state. The crystal-field theory completed by strong intra-atomic correlations and intersite spin-dependent interactions to the Quantum Atomistic Solid State Theory (QUASST), offers the meV energy scale needed for description of magnetic and electronic properties of compounds containing open-shell 3d, 4f, 5f atoms. The derived set of CEF parameters for the U3+ state reproduces both the INS excitations, temperature dependence of the heat capacity, large uranium magnetic moment as well as its direction.

description: It is customary for researchers and practitioners to fit linear models in order to predict NBA player's salary based on the players' performance on court. On the contrary, we focus on the players salary share (with regards to the team payroll) by first selecting the most important determinants or statistics (years of experience in the league, games played, etc.) and then utilise them to predict the player salaries by employing a non linear Random Forest machine learning algorithm. We externally evaluate our salary predictions, thus we avoid the phenomenon of over-fitting observed in most papers. Overall, using data from three distinct periods, 2017-2019 we identify the important factors that achieve very satisfactory salary predictions and we draw useful conclusions.
