description: A unique reconstruction of the image of a high redshift source galaxy responsible for multiple long arcs in the z = 0.4 cluster 0024+1654 is obtained by inverse lensing. Deep B and I imaging with the Hubble Space Telescope (Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by AURA, under NASA contract NAS 5-26555) enables high resolution of the arcs due to strong gravitational lensing of the background source. The gravitational lens in the foreground cluster is thus used to obtain a magnified view of the distant source. Four strongly lensed images of the source lead to a unique reconstruction. Each of the long arcs, when unlensed, leads to the same reconstructed source image exhibiting a beaded ring-like morphology. The U luminosity of the ring alone is equivalent to a normal galaxy. This is likely a galaxy in formation.

Detecting cells and cellular activity from two-photon calcium imaging data
Creators: name: Reynolds, Stephanie
Publisher: name: Imperial College London
Year: 2018

description: To understand how networks of neurons process information, it is essential to monitor their activity in living tissue. Information is transmitted between neurons by electrochemical impulses called action potentials or spikes. Calcium-sensitive fluorescent probes, which emit a characteristic pulse of fluorescence in response to a spike, are used to visualise spiking activity. Combined with two-photon microscopy, they enable the spiking activity of thousands of neurons to be monitored simultaneously at single-cell and single-spike resolution. In this thesis, we develop signal processing tools for detecting cells and cellular activity from two-photon calcium imaging data. Firstly, we present a method to detect the locations of cells within a video. In our framework, an active contour evolves guided by a model-based cost function to identify a cell boundary. We demonstrate that this method, which includes no assumptions about typical cell shape or temporal activity, is able to detect cells with varied properties from real imaging data. Once the location of a cell has been identified, its spiking activity must be inferred from the fluorescence signal. We present a metric that quantifies the similarity between inferred spikes and the ground truth. The proposed metric assesses the similarity of pulse trains obtained from convolution of the spike trains with a smoothing pulse, whose width is derived from the statistics of the data. We demonstrate that the proposed metric is more sensitive than existing metrics to the temporal and rate precision of inferred spike trains. Finally, we extend an existing framework for spike inference to accommodate a wider class of fluorescence signals. Our method, which is based on finite rate of innovation theory, exploits the known parametric structure of the signal to infer the unknown spike times. On in vitro imaging data, we demonstrate that the updated algorithm outperforms a state of the art approach.
Electrochemical generation-collection sensors for bioanalysis
Creators: name: Parinya, Seelanan
Publisher: name: Imperial College London
Year: 2018

description: Electrochemical generation-collection devices have potential for application in a wide range of analytical devices, both as free standing sensor systems and as components in analytical systems such as high performance liquid chromatography (HPLC) or flow injection analysis (FIA). The underlying principle is that an electrochemical reaction on one element is used to generate some chemical species which is then transported by diffusion or diffusion and convection to a second electrode where the electrochemical reaction is reversed. The fraction collected is a function of device geometry, operating conditions, any reaction of the generated species in bulk solution and mass transport. This thesis describes the construction of generation-collection sensors comprising coplanar inlaid microelectrodes of different size and shape: ring-disc and disc-disc in sizes ranging from 10 m to 100 m. Fabrication techniques including sputter-coating and embedding of wires were developed and are described. The sensors were characterised using scanning electron microscopy and their electrochemical characterisation was achieved using reversible outer sphere redox couples including ferrocene derivatives, ruthenium hexaammine (III/II) and ferro/ferricyanide. Experimental data are given for the effects of geometry, size and generator current density, particularly where this would affect the uniformity of the flux. Tests were also undertaken in specially built flow cells to assess their viability for application in FIA and LC detection. Where possible, performance in both the steady state and transient mode were compared with numerical and analytical models. Three specific bioanalytical applications were investigated and are described: (i) detection of peptides and amino acids using electrochemically generated bromine/ hypobromite (ii) electrochemical biuret detection and (iii) determination of titratable acidity and alkalinity (buffer capacity). Results for (i) showed more complex behaviour with the Pt-Pt dual microelectrode than that has been reported for macroelectrodes under similar system. Voltammetric results are reported. Electrochemical biuret systems showed less improvement in sensitivity with the generation-collection mode to small peptide molecules. For the buffer capacity sensor, both disc-disc and ring-disc geometries were investigated in a range of sizes 25 to 75 m for the disc and approximately 1 m for the ring. A pH sensitive surface was prepared by the deposition of hydrated iridium oxide on gold. Local pH changes were effect by electrolysis of the buffer solution. Experimental works emphasised the importance of controlling the current density to ensure that buffer capacity was not exceeded. An analytical model was of great use in optimising the device. Results are reported for various buffer systems comparing experiments with steady-state theory.
The Evolution of Viscous Inclined Disks in Axisymmetric and Triaxial Galaxies

Year: 1995
Subjects: subject: Astrophysics (astro-ph)

description: We have used a set of equations developed by Pringle (1992) to follow the evolution of a viscous twisted disk in a galaxy-like potential which is stationary or tumbling relative to inertial space. In an axisymmetric potential, the disk settles to the equatorial plane at a rate determined largely by the coefficient $ν_2$ associated with shear perpendicular to the local disk plane. If the disk is initially close to the galaxy equator, the rate at which the inclination decays is well described by the analytic formula of Steiman-Cameron and Durisen (1988); in a highly inclined disk, `breaking waves' of curvature steepen as they propagate through the disk, rendering the numerical treatment untrustworthy. In a triaxial potential which is stationary in inertial space, settling is faster than in an oblate or prolate galaxy, since the disk twists simultaneously about two perpendicular axes. If the figure of the potential tumbles about one of its principal axes, the viscous disk can settle into a warped state in which gas at each radius follows a stable tilted orbit which precesses so as to remain stationary relative to the underlying galaxy.

Searching for heavy neutral leptons at LHCb and SHiP
Creators: name: Redi, Federico Leo
Publisher: name: Imperial College London
Year: 2017

description: Heavy Neutral Leptons are very weakly interacting particles expected in many theories for the extension of the Standard Model. In this thesis two different studies are presented concerning Heavy Neutral Leptons. The first study presents details of the validation of the SHiP detector simulation software. Several models for the simulation of muon production at the beam dump are compared with data collected by the CHARM collaboration. The study shows that the simulation software gives a satisfactory simulation of the geometry of the muonic flux as well as of the energy deposition measurements. The second study is an inclusive search for a Heavy Neutral Lepton decaying at an isolated vertex. The search is performed using a $pp$-collision data sample collected at $\sqrt{s}=7$ and 8 TeV with the LHCb detector, corresponding to integrated luminosities of 1 and 2 fb$^{-1}$ respectively. No significant signal is observed in the mass range $2000 \le m_N \le 6200$ MeV, and therefore model independent limits are placed on the production cross-section times branching ratio as a function of the mass and lifetime of the Heavy Neutral Lepton. The limits are subsequently interpreted as model dependent limits on the mixing between the Heavy Neutral Lepton and the Standard Model muon neutrino as a function of the mass of the Heavy Neutral Lepton.
The role of neutrophil extracellular traps (NETs) in the pathogenesis of pulmonary hypertension (PH).
Creators: name: Aldabbous, Lulwah
Publisher: name: Imperial College London
Year: 2018

description: Rationale: Inflammation contributes to vasoconstriction and vascular remodelling in pulmonary hypertension (PH), but the mechanisms contributing to the disease are not fully understood. Recent data link neutrophil extracellular traps (NETs) and NET components with endothelial dysfunction, thrombosis, and lung injury. NETs, produced as a result of neutrophil cell death induced by inflammation or cytotoxic stress, comprise chromatin fibers associated with a number of proteins, including myeloperoxidase and neutrophil elastase. Hypothesis and Aims: I hypothesized that NETs may contribute to pulmonary vascular remodelling in PH. The aim of the present study was to measure the levels of NET markers in plasma of PH patients and to analyse the effects of NETs on human pulmonary artery endothelial cell (HPAEC) function in vitro. Methods and Results: Chronic thromboembolic pulmonary hypertension (CTEPH), patients and idiopathic pulmonary arterial hypertension (IPAH) patients showed increased plasma levels of NET components including myeloperoxidase, neutrophil elastase and circulating DNA, compared with healthy volunteers. Endarterectomy specimens from CTEPH patients and plexiform lesions in IPAH lungs showed accumulation of NET-forming peptidylarginine deiminase 4+ (PAD4) neutrophils and co-localization of NET markers, DNA, myeloperoxidase and citrullinated histone 3. Incubation of NETs with HPAECs in vitro activated transcription factor nuclear factor kappa B (NFκB), increased expression of pro-inflammatory and pro-angiogenic factors, compromised endothelial barrier function and induced endothelial angiogenesis. These effects depended on direct contact of NETs with the endothelial cell surface. NETs also increased Matrigel plug vascularization in mice, increased endothelin 1 (ET-1) release by endothelial cells and increased proliferation of pulmonary artery smooth muscle cells in vitro. Levels of ET-1 in plasma of CTEPH patients significantly correlated with the levels of NET markers in patient plasma. NETs-induced pro-angiogenic responses depended on myeloperoxidase/H2O2-induced activation of Toll-like receptor 4 (TLR4)/NFκB signalling. Conclusion: NETs- induced endothelial dysfunction is likely to play a contributory role in the pulmonary vascular remodelling in PH. Inhibition of NET components or NET formation in vivo may represent a new therapeutic approach in the treatment of PH.
A cross-sectional study to characterise young-onset diabetes in UK ethnic groups
Creators: name: Misra, Shivani
Publisher: name: Imperial College London
Year: 2017

description: Diabetes subtypes are challenging to differentiate, particularly in people who present at young age. Assigning the correct subtype of diabetes is critical as it informs treatment and misclassification can lead to erroneous management. The impact of ethnicity on diabetes phenotypes is poorly studied but recognition of diabetes subtypes within non-white ethnic groups, is increasingly problematic. Maturity onset diabetes of the young (MODY) is a monogenic form of diabetes that is frequently misdiagnosed in white populations and not widely studied in other ethnicities. The work in this thesis aims to investigate the phenotypes of young-onset diabetes across white, south Asian and African-Caribbean ethnic groups, with the aim of improving recognition of these phenotypes. Results from a retrospective analysis of referrals for MODY testing in the UK, showed a significantly lower detection rate of finding a positive MODY mutation in people referred from south Asian ethnicity compared to white European ethnicity. It was not clear if this significant disparity represented a lower prevalence of MODY in south Asian individuals or if there was a bias in testing referrals based on the traditional clinical criteria for MODY. To fully investigate this finding, the MY DIABETES study was initiated; a multi-centre cross-sectional study that systematically phenotypes young-onset diabetes across south Asian, African-Caribbean and white European ethnic groups. Fasting C-peptide and pancreatic auto-antibodies are used to stratify individuals for genetic testing of all known MODY genes. Results of the initial 728 participants recruited, showed an overall detection rate of 9.5% that was not significantly different by ethnicity and confirmed pathogenic MODY mutations were detected across all ethnic groups. These results suggest that a systematic approach to stratification in south Asian and African-Caribbean individuals may be warranted if clinical criteria are less sensitive due to the overlapping phenotypes of other types of diabetes in these groups.

description: We consider decentralized Energy Markets whose underlining power grid topology consists of generators, consumers, and transmission lines, and which is divided into regions. In the absence of a central System Operator, the Market Location Prices should be computed with coordination between the regions. The local regions perform local Optimal Power Flow (OPF) steps which are subsequently clued together with respect to certain operational constraints using the Alternating Direction Method of Multipliers (ADMM). This problem leads itself to a decentralized coordination problem and the Blockchain Technology seems to be its proper and effective backbone. The regions communicate through an Ethereum distributed application (dApp). The Proof of Authority (PoA) consensus algorithm is used, and blocks are created when an optimal global solution has been found. The integration of the Blockchain Technology in the ADMM algorithm is the main contribution of this paper.
Effect of trailing edge shape on the flow characteristics around an airfoil at low Reynolds number
Creators: name: Thomareis, Nikitas
Publisher: name: Imperial College London
Year: 2017

description: DNS of the flow fi eld around a NACA 0012 airfoil at Re = 50,000 and angle of attack 5 degrees with 3 different trailing edge shapes (straight, blunt and serrated) have been performed. Initially the time-averaged flow characteristics of the 3 trailing edges are studied. The presence of serrations in the trailing edge is found to create a spanwise pressure gradient, which is responsible for the development of a secondary flow pattern in the spanwise direction, and for the reduction of the wake de cit downstream of the troughs. The dominant flow structures and their frequencies are investigated for the straight and blunt trailing edges, using the Dynamic Mode Decomposition method (DMD) and resolvent analysis. Using these techniques we are able to identify and analyse the interactions between the modes which characterize the dynamic behaviour of the flow fi eld. It is shown that for the straight trailing edge airfoil, the DMD can capture the fundamental as well as the subharmonic of the Kelvin-Helmholtz instability that develops naturally in the separating shear layer. The blunt trailing edge results in periodic vortex shedding, with frequency close to the subharmonic of the natural shear layer frequency, which is found to have an upstream effect and force the separating shear layer into a lock-in state. A set of optimal responses, calculated to maximize the energy of the response, were used to accurately estimate the spectra in the most energetic points in the flow field. Lastly, a tripping method is applied which keeps the boundary layer attached. The pressure and skin-friction coefficients as well as the boundary layer pro files were significantly modified. Furthermore, the selection of the domain used to optimise the response, used in the resolvent analysis, was found to have an important effect on the determination of the optimal modes.
The development of organic semiconductors for p- and n-type accumulation mode organic electrochemical transistors (OECTs)
Creators: name: Giovannitti, Alexander
Publisher: name: Imperial College London
Year: 2017

description: The thesis reports on the development of organic semiconductors for p- and n-type accumulation mode organic electrochemical transistors (OECTs). First, the development of a series of alkoxy benzodithiophene (alkoxy-BDT) copolymers is presented. The materials series were prepared and characterised for their electrochemical redox activity in aqueous electrolytes. In addition, the materials were tested in OECTs where the performance differences between the copolymers were related to their microstructure and redox stability. After the successful development of p-type OECT materials, the redox stability of alkoxy-BDT copolymers was investigated, where a strong dependence of the electrochemical redox stability was observed. It was found that alkoxy-BDT copolymers with a large ionisation potential (IP) formed a quinone side product whilst copolymers with small IPs were found to be redox stable. The formation of the quinone structure affects the performance copolymers in OECTs significantly and the formation of the quinone must be avoided for use of materials in OECTs. Based on the results of the alkoxy-BDT copolymer study, a new copolymer was developed showing a high performance in accumulation mode OECTs. It was shown that the choice of the side chain is highly important to facilitate the copolymer with a high ion mobility. Finally, the development of the first accumulation mode ambipolar OECT material is reported. The design strategy for the polymer is presented and it was observed that a large electron affinity (EA) is needed to operate the n-type polymer with a high stability. This demonstration opens the possibility to develop complementary circuits and enable sensing of biomolecules with the aid of enzymatic reactions.

X-ray photoelectron spectroscopy for surface characterisation of the bio-stability of polyaniline Films
Creators: name: Mahat, Mohd
Publisher: name: Imperial College London
Year: 2016

description: This thesis explores the use of X-ray photoelectron spectroscopy (XPS) for characterising the bio-stability of polyaniline (PANI) films in biomedical applications. PANI has gained increasing interest in the literature due to its tuneable conductivity and variable oxidation states. There exist significant challenges for PANI. It is required to remain stable a high pHin order to avoid the loss of conductivity, due to the dopant leaching out from the polymer backbone. The first aspect of the thesis utilised XPS as an analytical technique to elucidate this phenomenon. Two types of dopant were selected to chemically dope the polyaniline-emeraldinebase (PANI-EB), followed by thin film fabrication by the spincoating technique. Results from XPS reveal that deprotonation occurs in response to the incubation in physiological conditions. The loss of dopant was observed, and is in agreement with previous findings. Additional methods of characterisation such as ToF-SIMS and UV-Vis were conducted, which support the findings of the XPS measurements. Since instability could lead to the impaired conductive function of PANI in biomedical applications, a suitable dopant ought to be explored. In the second project, a patch comprising of a bilayer film was fabricated. During the manufacturing process, a polymerised PANI was grown on a chitosan layer, with phytic acid (PA) as a dopant. XPS was again used to characterise the surface stability. The patch was found to be stable for up to 14 days, as the dopant signals remained detectable. Depth profile analysis showed that the PA not only works as the dopant, but also crosslinked the PANI and chitosan layers. High pressure XPS (HPXPS) has been performed as an advanced technique to reveal the surface chemistry of PANI film at elevated pressure, in a water environment, in an attempt to measure surface chemistry under realistic conditions. To the best of our knowledge this is the first report of a conducting polymer film specifically PANI, measured using HPXPS. Collectively, XPS has been used as a primary tool in understanding the surface chemistry of the PANI surfaces and the designated bilayer system.
The isotopic compositions of cadmium and other volatile trace metals in Earth and chondrites
Creators: name: Palk, Emeliana Maria
Publisher: name: Imperial College London
Year: 2016

description: The origin of Earth’s volatile elements is unresolved with different views on the extent to which volatiles were delivered during the main accretion stage or by a volatile-rich late veneer. This question is addressed here through isotopic investigations of the volatile element Cd. New Cd isotope data were obtained for both terrestrial rocks and carbonaceous chondrites, and these yield well-constrained estimates of ε114/110Cd = –0.9 ± 0.5 and +3.2 ± 0.8 for the Cd isotope compositions of the bulk silicate Earth and carbonaceous chondrites, respectively. Metal-silicate partitioning experiments conducted at elevated temperature and pressure, furthermore, demonstrate that partitioning of slightly siderophile Cd during segregation of Earth’s core was not accompanied by Cd isotope fractionation. Accretion modelling with these constraints suggests that Earth’s main accretionary component was characterised by ε114/110Cd ≈ –1.6 for a late veneer with 0.5% of Earth’s mass (ME) and by ε114/110Cd ≈ –5 for a larger late veneer with 1.7% ME. Volatiles condensed late in the inner solar nebula, and such material, contributing to the main accretion stage of Earth, probably featured a lighter Cd isotope composition than earlier condensates, as represented by carbonaceous chondrites. Notably, there is no evidence from meteorites that material with an unusually low ε114/110Cd of about –5 was ever common in the inner solar system. This renders scenarios where a large proportion of Earth’s Cd and other volatiles were delivered by a large late veneer with ≥ 1.7% ME much more unlikely than accretion models that encompass only a minor addition of volatile-rich material after cessation of core formation. An investigation into the application of the extinct 205Pb – 205Tl chronometer to enstatite and ordinary chondrites was also carried out and showed that such work is severely restricted by both terrestrial Pb contamination and Tl stable isotope fractionation from parent body processing.

description: The relation between thermal fluctuations and the mechanical response of a free membrane has been explored in great detail, both theoretically and experimentally. However, understanding this relationship for membranes, locally pinned by proteins, is significantly more challenging. Given that the coupling of the membrane to the cell cytoskeleton, the extracellular matrix and to other internal structures is crucial for the regulation of a number of cellular processes, understanding the role of the pinning is of great interest. In this manuscript we consider a single protein (elastic spring of a finite rest length) pinning a membrane modelled in the Monge gauge. First, we determine the Green$'$s function for the system and complement this approach by the calculation of the mode coupling coefficients for the plane wave expansion, and the orthonormal fluctuation modes, in turn building a set of tools for numerical and analytic studies of a pinned membrane. Furthermore, we explore static correlations of the free and the pinned membrane, as well as the membrane shape, showing that all three are mutually interdependent and have an identical long-range behaviour characterised by the correlation length. Interestingly, the latter displays a non-monotonic behaviour as a function of membrane tension. Importantly, exploiting these relations allows for the experimental determination of the elastic parameters of the pinning. Last but not least, we calculate the interaction potential between two pinning sites and show that, even in the absence of the membrane deformation, the pinnings will be subject to an attractive force due to changes in membrane fluctuations.

description: It is suggested that the outflowing plasma in the jets of active galactic nuclei (AGNs) is inhomogeneous and consists of separate clouds. These clouds are strongly magnetized and move away from the central engine at relativistic speeds. The clouds interact with an ambient medium which is assumed to be at rest. In the process of this interaction, particles of the ambient medium are accelerated to high energies at the cloud front and flow ahead of the front. It is shown that the radiation of the accelerated particles may be responsible for the X-ray and $γ$-ray emission from AGN jets. TeV $γ$-ray emission is generated in the inner parts of AGN jets where the Lorentz factor of the cloud fronts is $Γ_0\geq 30$, while GeV $γ$-ray emission emanates from the outer parts of AGN jets where $Γ_0$ is $\sim 10$.

The effect of hydration and chemical treatments on natural fibres
Creators: name: Ali, Naima
Publisher: name: Imperial College London
Year: 2018

description: This Thesis reports on an investigation of the interaction of keratin fibres with different actives both in liquid and vapour phases. The extent and rate of small molecule uptake with the virgin human and chemically treated hair fibres via experimental sorption was studied with molecules designed to modify keratin chemistry, ammonia and mono-ethanol amine, as well as water vapour and selected organic molecules. Thermal, mechanical characterisation, protein loss and SEM were also performed. The diffusion kinetics of MEA into keratin fibres for 0.1-5% v/v MEA in water at 30 and 50oC exhibited two clear regimes of sorption behaviour. Single fibre tensile tests showed that the Young’s modulus and the tensile failure stress for 5% MEA treated fibres were 50% lower after 9 hours of treatment. SEM images and protein content analysis evidenced significant surface damage as well as high levels of protein loss, confirming for the first time this important damage process. The additives salicylic acid and isosteryl isosterate were shown to reverse the moisture losses associated with significant fibre damage e.g. 5% MEA. A range of hydrophobic and hydrophilic sorbates confirmed the hydrophilic sorption behaviour of hair. Gravimetric water sorption experiments confirmed that chemically induced damage affected levels of water and organic vapour sorption by hair. Non-polar sorbates exhibited low uptake for both damaged and virgin hair. The presence of hysteresis in all samples may be related to the swelling upon sorption. Ramped sorption experiments confirmed a potential transition event at 64% RH, which maybe the relative humidity glass transition of the fibres. A novel inverse gas chromatographic method for determining the surface area of virgin hair to be 0.22 m2/g and for damaged fibres 0.12 m2/g. The effect of humidity on the surface area of hair for the first time is also reported, showing clear humidity induced swelling of the fibres.

We describe the theoretical framework of our technique and apply it to a P$^3$M cosmological simulation performed on a cube of $100$ Mpc on a side, obtaining a new ``simulation'' of $800$ Mpc on a side. We study the effect of the power added by long waves by mean of several statistics of the density and velocity field, and suggest possible applications of our method to the study of the large-scale structure of the universe.

Damage due to liver disease occurs in the form of scarring of healthy liver tissue, a process known as fibrosis. Chronic fibrosis can lead to liver cirrhosis, a condition that is irreversible and often requires liver transplantation. Cirrhosis manifests itself in the form of increased tissue stiffness and decreased tissue permeability, which then leads to a marked decrease in blood perfusion and functioning of the liver tissue. As a homeostatic response, hepatic portal blood pressure also increases, which then leads to an increased outflow of excess interstitial fluid across the surface of the liver and into the surrounding peritoneal cavity. The abnormal accumulation of fluid in the peritoneal cavity is known as ascites and is characterised by large abdominal girth, abdominal pain and discomfort. The aim of this thesis was to model the microcirculation of blood and interstitial fluid in the liver, so as to investigate the changes in vasculature that lead to impaired blood perfusion and the formation of ascites. To that end, we have developed a dual-porosity, dual-permeability deformable model of the liver tissue using the Biot theory of poroelasticity. We then used the model as part of a compartmental model of the peritoneal cavity and investigated the effect of liver disease (fibrosis/cirrhosis) on the accumulation of fluid in the peritoneal cavity. By varying the degree of liver tissue stiffness, we simulated and compared different stages of liver fibrosis, as well as predicted the severity of the resulting ascites. This makes our model an improvement on the current literature, with the aim of future use in informing and improving disease treatment strategies.

description: We use UKIRT and ASCA observations to determine the nature of a high redshift (z=2.35) narrow-line AGN, previously discovered by Almaini et al. (1995). The UKIRT observations show a broad Halpha line while no Hbeta line is detected. This together with the red colour (B-K=5.4) suggest that our object is a moderately obscured QSO (Av>3), in optical wavelengths. The ASCA data suggest a hard spectrum, probably due to a large obscuring column, with a photon index of 1.93 (+0.62, -0.46), NH~10^23. The combined ASCA and ROSAT data again suggest a heavily obscured spectrum (NH~10^23 or Av~100). In this picture, the ROSAT soft X-ray emission may arise from electron scattering, in a similar fashion to local Seyfert 1.9. Then, there is a large discrepancy between the moderate reddening witnessed by the IR and the large X-ray absorbing column. This could be possibly explained on the basis of e.g. high gas metallicities or assuming that the X-ray absorbing column is inside the dust sublimation radius. An alternative explanation can be obtained when we allow for variability between the ROSAT and ASCA observations. Then the best fit spectrum is still flat, 1.35 (+0.16, -0.14), but with low intrinsic absorption in better agreement with the IR data, while the ROSAT normalization is a factor of two below the ASCA normalization. This object may be one of the bright examples of a type-II QSO population at high redshift, previously undetected in optical surveys. The hard X-ray spectrum of this object suggests that such a population could make a substantial contribution to the X-ray background.

description: The subject of sustainability has spread rapidly in recent years in the scientific literature and in publications of all kinds. It is one of those concepts that, obviously, are not explicit and can be found in justifications of all kinds, from the promotion of a project or its rejection, to marketing campaigns for a product, to the viability of companies or to the explanation of his failure.
The epidemic theory of William Goffman and Vaun A. Newill is proposed to explain the propagation pattern of this concept in the scientific field. To this end, the authors of articles of scientific publications on Ecology and Land Planning indexed in the Web of Science platform of information, from 1987 to 2015, which contain the concept of sustainability as a theme, are taken.
The epidemic theory is part of the bibliometric studies, in the area of Information Science and uses mathematical models to outline the dissemination of certain topics or lines of research. It arises as an attempt to obtain quantifiable and objective bases to improve information retrieval systems by providing data that allows understanding the development of a discipline and thus provide the type of documents that are most pertinent to the scientific community.
The aim is to demonstrate the relevance of the application of the epidemic theory to determine the existence of an epidemiological pattern in the growth of the number of authors of scientific literature on the topic of sustainability at an international level. In addition, the basic bibliometric indicators that characterize the authors and their articles are presented in an area of great importance and impact.
Among the main conclusions that are highlighted is the existence of an epidemic of the concept of sustainability in the area of Ecology and Territorial Planning, the growing trend of the topic at the international level and the relevance of the Goffman model as an indicator of high importance to determine the existance of an epidemic.
Gluon jet function at three loops in QCD

description: We present here the first result on the three-loop gluon jet function in perturbative QCD. Using the three-loop coefficient functions [1,2] for deep-inelastic scattering via the exchange of a virtual photon that couples to quarks or a scalar that couples to gluons and employing the KG equation, renormalization group invariance and factorization theorem, we obtain both the quark and the gluon jet functions up to the three-loop level. The former agrees with the recent result [3]. These jet functions being universal ingredients for many collider and decay processes, will play an important role in the phenomenological studies at the Large Hadron Collider.

description: We search for nuclear recoil signals of dark matter models with a light mediator using data taken from a p-type point-contact germanium detector of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on the DM-nucleon interaction cross section from 205.4 kg-day exposure data are derived, excluding new parameter space in 2~5 GeV DM mass when the mediator mass is comparable to or lighter than the typical momentum transfer. We further interpret our results to constrain a specific self-interacting dark matter model with a light mediator coupling to the photon through kinetic mixing, and set experimental limits on the model parameter region favored by astrophysical observations.
A COMPARISON OF ORDINARY LEAST SQUARES AND LEAST ABSOLUTE ERROR ESTIMATION

description: In a linear dynamic model with heteroscedastic errors, we compare some aspects of ordinary least squares and least absolute error estimation. After deriving the properties of the estimators and the Wald, Lagrange multiplier and Likelihood ratio tests under a local alternative, we derive the Hausman test comparing the estimators. From this, and the equivalent generalized method of moment tests, we obtain as special cases tests for specification and symmetry based on the signs of the residuals from ordinary least squares. We also show that in the presence of heteroscedasticity, asymmetry can affect the estimates of all the parameters, not just the constant term.

description: We present stellar evolutionary models covering the mass range from 0.4 to 1 Msun calculated for metallicities Z=0.020 and 0.001 with the MHD equation of state (Hummer & Mihalas, 1988; Mihalas et al. 1988; Däppen et al. 1988). A parallel calculation using the OPAL (Rogers et al. 1996) equation of state has been made to demonstrate the adequacy of the MHD equation of state in the range of 1.0 to 0.8 Msun (the lower end of the OPAL tables). Below, down to 0.4 Msun, we have justified the use of the MHD equation of state by theoretical arguments and the findings of Chabrier & Baraffe (1997). We use the radiative opacities by Iglesias & Rogers (1996), completed with the atomic and molecular opacities by Alexander & Fergusson (1994). We follow the evolution from the Hayashi fully convective configuration up to the red giant tip for the most massive stars, and up to an age of 20 Gyr for the less massive ones. We compare our solar-metallicity models with recent models computed by other groups and with observations. The present stellar models complete the set of grids computed with the same up-to-date input physics by the Geneva group [Z=0.020 and 0.001, Schaller et al. (1992), Bernasconi (1996), and Charbonnel et al. (1996); Z=0.008, Schaerer et al. (1992); Z=0.004, Charbonnel et al. (1993); Z=0.040, Schaerer et al. (1993); Z=0.10, Mowlavi et al. (1998); enhanced mass loss rate evolutionary tracks, Meynet et al. (1994)].
