description: We present simulations of the cluster distribution in several dark matter models, using an optimized version of the truncated Zel'dovich approximation (TZA). We compare them with N-body cluster simulations and find that the TZA provides a very accurate description of the cluster distribution as long as fluctuations on the cluster mass scale are in the mildly non-linear regime. The simulated dark matter models are: Standard CDM (SCDM), Tilted CDM (TCDM) with n=0.7, Cold+Hot DM (CHDM) with 30% of hot component, low Hubble constant (h=0.3) CDM (LOWH) and a spatially flat low-density CDM model with Ω_0=0.2. We compare the simulations with a redshift sample of Abell/ACO clusters, using the integral of the 2-point correlation function and the probability density function. We find that the best models at reproducing the data are CHDM and LCDM. All the other models are ruled out. The reduced skewness S_3 is fairly constant with S_3=1.9, independent of the DM model and consistent with observational data. The abundances of clusters predicted using the Press--Schechter theory provide strong constraints: only the CHDM, LOWH and LCDM models appear to produce the correct number-density of clusters.

description:

Global Digital Elevation Models (DEMs) are widely employed in geoarchaeology. Usually, their adequacy for particular landscapes is not tested. We assessed 30m-resolution-DEMs (ASTER, SRTM, ALOS, EU-DEM, NASADEM, NEXTMap) with local precision datasets. Our results reveal considerable differences (ASTER unsuitable for the region, NEXTMap and EU-DEM fit most closely to our reference model). This outcome does not necessarily apply to all similar regions. It rather stresses the need for a check of DEMs’ quality in any given study area, and it encourages the use of detailed topographic visualisations of DEMs in absence of suitable reference data.

Dedication by Hieron of Syracuse in Olympia
Creators: name: Chies, Enrico
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description: The inscription, carved on a bronze Etruscan helmet, was found in 1817 among the ruins of Olympia. The text of the inscription is a dedication to Zeus made by Hieron, tyrant of Syracuse, after his naval victory over the Etruscans at Kyme (474-473 BC). The inscription provides scholars with informations about both Deinomenid’s communicative strategies in a Panhellenic context and Hieron’s politics at the beginning of the fifth century BC. A comparison between the inscription and Pindar’s Pythian I allows scholars to study two very different ways of celebration of the same military event.

description: Phosphor-converted LEDs (pc-LEDs) have been employed for solid-state lighting applications. The use of phosphor helped in achieving desirable properties such as good color rendition (CRI), coordinated color temperature (CCT), etc. White LED lamps have been fabricated using downshifting phosphors. However, few efforts have been made to develop ultraviolet (UV) emitting LEDs using downshifting phosphors. On the other hand, numerous reports are available in the literature on directly UV emitting LED. Such LEDs are available commercially. Cost and efficiencies of directly UV emitting LED chips vary. It could be useful to coat suitable phosphors of low cost, excitable by shorter wavelengths on UV emitting chips to obtain pc-LED emitting at longer wavelength UV region. This concept is demonstrated here by using suitable phosphors and a chip emitting at 275 nm to obtain pc-UVLED emitting in 300–340 nm range.
Polysemy as Hermeneutic Key in Ibn ʿArabī’s Fuṣūṣ al-Ḥikam
Creators: name: Salvaggio, Federico
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The present contribution discusses the role of polysemy within Ibn ʿArabī’s hermeneutic approach in the Fuṣūṣ al-Ḥikam. It argues that the Andalusian master’s conception of polysemy bears implications that stretch far beyond the field of Arabic linguistics, strictly understood, and that are tightly related to his vision of the polysemous and pansemiotic nature of existence. Thus, when investigated in the light of his metaphysical views, Ibn ʿArabī’s hermeneutic use of word polysemy, as arbitrary as it might appear at first sight, results perfectly consistent with his conception of the descent of language through multiple states of being and of the conjunction of form and meaning in the world of imagination. These metaphysical premises provide the epistemological foundations for Ibn ʿArabī’s linguistic and hermeneutic practices and build up one the finest and most complete metaphysical conceptions of language elaborated within the broader context of what might be defined the domain of ‘Islamic linguistics’.

description: Transverse momentum spectra of different types of particles produced in mid-rapidity interval in central and peripheral gold-gold (Au-Au) collisions, central and peripheral deuteron-gold ($d$-Au) collisions, and inelastic (INEL) or non-single-diffractive (NSD) proton-proton ($pp$) collisions at the Relativistic Heavy Ion Collider (RHIC), as well as in central and peripheral lead-lead (Pb-Pb) collisions, central and peripheral proton-lead ($p$-Pb) collisions, and INEL or NSD $pp$ collisions at the Large Hadron Collider (LHC) are analyzed by the blast-wave model with Boltzmann-Gibbs statistics. The model results are largely consist with the experimental data in special transverse momentum ranges measured by the PHENIX, STAR, ALICE, and CMS Collaborations. It is showed that the kinetic freeze-out temperature of emission source is dependent on particle mass, which reveals the scenario for multiple kinetic freeze-out in collisions at the RHIC and LHC. The scenario for single or double kinetic freeze-out is not observed in this study.

The Evolution and Luminosity Function of Quasars from Complete Optical Surveys

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

description: We use several quasar samples to determine the density and luminosity evolution of quasars. Combining different samples and accounting for varying selection criteria require tests of correlation and the determination of distributions for multiply truncated data. We describe new non-parametric techniques for accomplishing these tasks, which have been developed recently by Efron and Petrosian (1998). We use matter dominated cosmological models with either zero cosmological constant or zero spatial curvature. Of the two most common models of luminosity evolution, L = exp(k t(z)) and L = (1+z)^k', we find the second model to be a better description of the data at all luminosities; we find k' = 2.58 ([2.14,2.91] one sigma region) for the Einstein - de Sitter model. Using this form of luminosity evolution we determine a global luminosity function and the evolution of the co-moving density for the two types of cosmological models. For the Einstein - de Sitter cosmological model we find a relatively strong increase in co-moving density up to a redshift of about 2, at which point the density peaks and begins to decrease rapidly. This is in agreement with results from high redshift surveys. We find some co-moving density evolution for all cosmological models, with the rate of evolution lower for models with lower matter density. We find that the local cumulative luminosity function exhibits the usual double power law behavior. The luminosity density (i.e. the total rate of energy output of quasars) is found to increase rapidly at low redshift and to peak at around z = 2. Our results for the luminosity density are compared to results from high redshift surveys and to the variation of the star formation rate with redshift.

Structure preserving reduced order modeling for gradient systems

description: Minimization of energy in gradient systems leads to formation of oscillatory and Turing patterns in reaction-diffusion systems. These patterns should be accurately computed using fine space and time meshes over long time horizons to reach the spatially inhomogeneous steady state. In this paper, a reduced order model (ROM) is developed which preserves the gradient dissipative structure. The coupled system of reaction-diffusion equations are discretized in space by the symmetric interior penalty discontinuous Galerkin (SIPG) method. The resulting system of ordinary differential equations (ODEs) are integrated in time by the average vector field (AVF) method, which preserves the energy dissipation of the gradient systems. The ROMs are constructed by the proper orthogonal decomposition (POD) with Galerkin projection. The nonlinear reaction terms are computed efficiently by discrete empirical interpolation method (DEIM). Preservation of the discrete energy of the FOMs and ROMs with POD-DEIM ensures the long term stability of the steady state solutions. Numerical simulations are performed for the gradient dissipative systems with two specific equations; real Ginzburg-Landau equation and Swift-Hohenberg equation. Numerical results demonstrate that the POD-DEIM reduced order solutions preserve well the energy dissipation over time and at the steady state.

description: A ROSAT HRI image of the hyperluminous infrared galaxy IRAS P09104+4109 shows extended X-ray emission peaked around the central galaxy in a profile characteristic of a cooling flow. The inferred soft X-ray luminosity is comparable to that detected with ASCA. The ASCA spectrum is well fit by a cooling flow spectrum, indicating a mass cooling rate of about 1000 Msunpyr. The cooling flow dominates the total luminosity of the surrounding cluster. Any contribution from a hidden AGN in the host galaxy to either the total ASCA spectrum or the HRI image is small.

description: Although squamates are commonly found in Cenozoic South American deposits, most findings correspond to fragmentary cranial materials or isolated vertebrae. Among the known South American vertebrate fossil localities, the lower section of the Chichinales Formation (Early Miocene, Colhuehuapian South American Land Mammal Age [SALMA]), in Paso Córdoba Protected Natural Area, Río Negro Province, Argentina, recently yielded an almost complete skull of a previously unknown teiid lizard. Here, we provide a detailed description of this new fossil, based on stereoscopic and high-resolution X-ray computed tomography (CT scan) analyses. Our phylogenetic analysis recovered the new fossil within the monophyletic genus Callopistes, as the sister group of the fossil C. bicuspidatus from upper Miocene–lower Pliocene sediments (Montehermosan SALMA) of the Monte Hermoso Formation. The new species antedates the oldest previously known fossil record of the genus by at least 14 Ma, providing a minimum age of origin for the genus of approximately 20.1 Ma (based on recent revisions of the Cenozoic fossil record of SALMA). The current distribution of the two known extant species of Callopistes and the locality from which the new taxon was recovered indicate that this genus had a much broader distribution in the past that included cis-Andean areas of Patagonia during the Miocene. Our phylogenetic results further suggest that Tupinambis uruguaianensis should be allocated to the genus Dracaena. http://zoobank.org/urn:lsid:zoobank.org:pub:452C7D2A-6819-4488-9C28-1020EBD71F91 SUPPLEMENTAL DATA—Supplemental materials are available for this article for free at www.tandfonline.com/UJVP Citation for this article: Quadros, A.

description: We present the very first robust Bayesian Online Changepoint Detection algorithm through General Bayesian Inference (GBI) with $β$-divergences. The resulting inference procedure is doubly robust for both the parameter and the changepoint (CP) posterior, with linear time and constant space complexity. We provide a construction for exponential models and demonstrate it on the Bayesian Linear Regression model. In so doing, we make two additional contributions: Firstly, we make GBI scalable using Structural Variational approximations that are exact as $β\to 0$. Secondly, we give a principled way of choosing the divergence parameter $β$ by minimizing expected predictive loss on-line. Reducing False Discovery Rates of CPs from more than 90% to 0% on real world data, this offers the state of the art.

3D printing versus foaming of melt-derived bioactive glasses for bone regeneration
Creators: name: Nommeots-Nomm, Amy Elizabeth
Publisher: name: Imperial College London
Year: 2015

description: Bioactive glasses have the ability to regenerate bone defects as they form a rapid bond with bone and their dissolution products can stimulate new bone growth. The original Bioglass® 45S5 composition (46.1 mol% SiO2, 26.9 mol% CaO, 24.4 mol% Na2O, and 2.6 mol% P2O5) is available as a clinical product in a particulate form, but surgeons require scaffolds that can act as temporary templates for bone repair. Bioglass 45S5 cannot be made into porous scaffolds while maintaining an amorphous glass structure, due to its susceptibility to crystallise during sintering. New melt-derived glass compositions have recently been developed which avoid crystallisation, enabling bioactive glasses to be made into porous constructs. The aim of this thesis was to investigate the relationship between glass composition and scaffold production techniques. Three glasses compositions were used, ICIE16 (49.46 SiO2, 36.27 CaO, 6.6 Na2O, 1.07 P2O5 and 6.6 K2O, in mol%), 13-93 (54.6 SiO2, 22.1 CaO, 6.0 Na2O, 1.7 P2O5, 7.9 K2O, 7.7 MgO, in mol%) and SBP-3 (44.5 SiO2, 17.8 CaO, 4.0 Na2O, 4.5 P2O5, 4.0 K2O, 7.5 MgO, 17.8 SrO, in mol%), each with an extended thermal processing window. These glasses were made into 3D scaffolds utilising two processing techniques: an adapted gel-cast foaming and, for the first time, robocasting. Here we present the adaption and optimisation of these techniques. The three glass compositions, ICIE16, 13-93 and SBP-3, all have different modified network connectivities (mean number of bridging Si-O-Si bonds per silicon atom, NC’) of 2.13, 2.84 and 3.01 respectively. In vitro and in vivo analysis were completed to understand how the different glass chemistry affected their bioactivity and dissolution characteristics. The composition of ICIE16 chemistry was the most similar to the original 45S5 composition was shown to promote and sustain better bone ingrowth than comparable scaffolds produced from SBP-3.

description: The current paper aimed to highlight the role of nutraceuticals rich in zinc and branched chain amino acids (BCAAs) for improving the quality of life (QoL) in patients with chronic liver disease (CLD), hepatic encephalopathy (HE), and geriatrics. Well-done works based on evidence-based approach were studied thoroughly in order to define the CLD and HE and extract an informative and concise report with valuable knowledge about the important role of zinc and BCAAs as an adjuvant nutraceutical therapy included in the treatment protocol of the CLD and HE, with many health benefits for geriatrics health. Novel nutraceutical formulations structured on scientific basis according to official guidelines were outlined as beneficial dietary supplements containing whey protein as a functional food of milk derivatives with proven health benefits and valuable content (18%) of BCAAs, fortified with a bunch of vitamins, minerals, steviol glycosides (SGs) and natural flavors. It could be concluded the valuable role of zinc and BCAAs in improving QoL in patients with CLD, HE, and geriatrics.
Electronic structure, transport properties and doping of wide-band gap semiconducting oxides NixMg1-xO and BaSnO3
Creators: name: Niedermeier, Christian Alexander
Publisher: name: Imperial College London
Year: 2016

description: Wide-band gap semiconducting oxides combine high electrical conductivity with optical transparency and find important applications as transparent contacts in solar cells, energy-efficient smart windows and thin film transistors used in flat-panel displays for smartphones and tablets. Among the material family of transparent conducting oxides, In2O3, SnO2, ZnO and CdO are the most prominent examples which all exhibit excellent n-type conductivity. Transition metal oxides such as Cu2O, CuAlO2 and NiO were investigated for their p-type conductivity, which remains a great challenge to achieve in oxide semiconductors. This thesis presents an investigation of the electronic structure and transport properties of NixMg1-xO, a fully miscible solid solution of NiO and MgO which allows for band gap tuning in the deep ultraviolet spectral region. Both materials crystallize in the cubic rock-salt structure with nearly identical lattice parameters, but their alloys exhibit an unusually large, non-parabolic band gap bowing which has led to controversial discussions in the literature. The second part of this thesis focusses on the thin film crystal growth, the electron transport properties and doping in the ideal cubic perovskite BaSnO3, which recently attracted significant interest as high-mobility electron transport material for oxide electronics composed of earth-abundant elements. An effective solid phase epitaxy method for preparation of high-mobility La:BaSnO3 films is developed, employing the room temperature-deposited nanocrystalline films as precursor. Furthermore, the first experimental report of interstitial H-doping of BaSnO3 films is demonstrated, presenting a promising n-type doping alternative for achieving excellent conductivity. Finally, the origin of the exceptionally high room temperature mobility is investigated through an in-depth characterization of the electron effective mass and carrier scattering mechanisms in epitaxial La:BaSnO3 thin films.

description: Using adaptive optics at the ESO 3.6m telescope, we obtained diffraction limited JHK-images of the region around the Herbig AeBe star NX Pup. We clearly resolved the close companion (sep. 0.128") to NX Pup -- originally discovered by HST -- and measured its JHK magnitudes. A third object at a separation of 7.0" from NX Pup was identified as a classical T Tauri star so that NX Pup may in fact form a hierarchical triple system. We discuss the evolutionary status of these stars and derive estimates for their spectral types, luminosities, masses and ages.

description: Using \emph{RXTE}, \emph{Chandra}, \emph{XMM-Newton} and \emph{Swift} observations, we for the first time construct the power spectra and torque noise strengths of magnetars. For some of the sources, we measure strong red noise on timescales months to years which might be a consequence of their outbursts. We compare noise strengths of magnetars with those of radio pulsars by investigating possible correlations of noise strengths with spin-down rate, magnetic field and age. Using these correlations, we find that magnetar noise strengths are obeying similar trends with radio pulsars. On the contrary, we do not find any correlation between noise strength and X-ray luminosity which was seen in accretion powered pulsars. Our findings suggest that the noise behaviour of magnetars resembles that of radio pulsars but they possess higher noise levels likely due to their stronger magnetic fields.

description: In this paper, we study the formation and chemical evolution of the Milky Way disc with particular focus on the abundance patterns ([$α$/Fe] vs. [Fe/H]) at different Galactocentric distances, the present-time abundance gradients along the disc and the time evolution of abundance gradients. We consider the chemical evolution models for the Galactic disc developed by Grisoni et al. (2017) for the solar neighborhood, both the two-infall and the one-infall ones, and we extend our analysis to the other Galactocentric distances. In particular, we examine the processes which mainly influence the formation of the abundance gradients: the inside-out scenario, a variable star formation efficiency, and radial gas flows. We compare our model results with recent abundance patterns obtained along the Galactic disc from the APOGEE survey and with abundance gradients observed from Cepheids, open clusters, HII regions and PNe. We conclude that the inside-out scenario is a key ingredient, but cannot be the only one to explain abundance patterns at different Galactocentric distances and abundance gradients. Further ingredients, such as radial gas flows and variable star formation efficiency, are needed to reproduce the observed features in the thin disc. The evolution of abundance gradients with time is also shown, although firm conclusions cannot still be drawn.

description: Jardiel Poncela orientó parte de sus esfuerzos literarios hacia la composición de sus acotaciones escénicas, aspecto fundamental de su teatro y dotadas de características tan peculiares que, a menudo, se convierten en piezas decisivas en la interpretación de la escritura dramática del autor. A pesar de que la crítica, en ocasiones, ha subrayado este factor, faltan estudios más pormenorizados sobre la cuestión, lo que es el objetivo de este artículo. Con este propósito, se analizan algunos ejemplos pertenecientes a cinco comedias de Jardiel, en los que destacan mecanismos retóricos, lingüísticos, estilísticos, con los que el autor parece manifestar su presencia en las acotaciones teatrales.

Publishing Complexity in the Digital Humanities

description:

When we talk about characteristics of Digital Humanities (DH), digital publishing certainly is a prominent domain to mention. Open access papers and books, blogging, collaborative writing, and digital editions have become deeply rooted in the DH, reflecting a self-confident culture of Open Science. The rational constitution of our writings, however, has received far less attention: How can we design digital publications that mirror epistemological implications of DH methods and the composition of our arguments and narratives better than current publishing formats? In this paper, I argue that the DH need formats that exceed traditional texts and their rather linear design. Digital publishing that provides (meta) data or remarks on applied methods as mere supplements would not be enough, too. Those elements are integral parts of a scholarly demonstration and they should be presented as such. They must be visible as constituents of our sense-making. We need media that depict the complex nature of data-driven research. Interlinked and multimodal digital publishing seems to lead in the right direction. I elaborate on this matter from a theoretical point of view by building on research on hypertext. I will also point to first successful attempts of implementation. Refining these approaches promises to facilitate the presentation of intricate sense-making in the DH.

Evidence For Recent Accretion in Nearby Galaxies

description: I discuss observations of magnitude residuals from the B-band Tully-Fisher relationship, B-V color, chemical abundance gradients, and asymmetries in the H I and stellar disks of nearby spiral galaxies within the context of a model in which small satellites or H I clouds are accreted onto the outer disks of spiral galaxies. Correlations between the various observables support the hypothesis that accretion dilutes the gas phase abundances in the outer disk, steepens the abundance gradient across the disk, increases the star formation rate, and creates asymmetries in the outer disk. By estimating the duration of steep abundance gradients, elevated rates of star formation, or outer disk asymmetries, constraints can be placed on the rate of accretion events. The data suggest that accretion events at the current time are common.

description: We extend previous calculations of leading-order correlation functions of spin-0 and spin-1 light quarkonium hybrids to include QCD condensates of dimensions five and six, with a view to improving the stability of QCD sum-rules analyses in previously unstable channels. Based on these calculations, prior analyses in the literature, and its phenomenological importance, we identify the exotic $J^{PC}=0^{+-}$ channel as the most promising for detailed study. Using Gaussian sum-rules constrained by the Hölder inequality, we calculate masses of light (nonstrange and strange) quarkonium hybrid mesons with $J^{PC}=0^{+-}$. We consider single narrow, single wide, and double narrow resonance models, and find that the double narrow resonance model yields the best agreement between QCD and phenomenology. In both non-strange and strange cases, we find hybrid masses of $2.60$ GeV and $3.57$ GeV.

description: When two 2D electron gas layers, each at Landau level filling factor $ν=1/2$, are close together a condensate of interlayer excitons emerges at low temperature. Although the excitonic phase is qualitatively well understood, the incoherent phase just above the critical layer separation is not. Using a combination of interlayer tunneling spectroscopy and conventional transport, we explore the incoherent phase in samples both near the phase boundary and further from it. In the more closely spaced bilayers we find the electronic spectral functions narrower and the Fermi energy of the $ν= 1/2$ composite fermion metal smaller than in the more widely separated bilayers. We attribute these effects to a softening of the intralayer Coulomb interaction due to interlayer screening.

description: In models with colored particle $\mathcal{Q}$ that can decay into a dark matter candidate $X$, the relevant collider process $pp\to \mathcal{Q}\bar{\mathcal{Q}}\rightarrow X\bar{X}+$jets gives rise to events with significant transverse momentum imbalance. When the masses of $\mathcal{Q}$ and $X$ are very close, the relevant signature becomes monojet-like, and Large Hadron Collider (LHC) search limits become much less constraining. In this paper, we study the current and anticipated experimental sensitivity to such particles at the High-Luminosity LHC at $\sqrt{s}=14\,\mathrm{TeV}$ with $\mathcal{L}=3\,\mathrm{ab}^{-1}$ of data and the proposed High-Energy LHC at $\sqrt{s}=27\,\mathrm{TeV}$ with $\mathcal{L}=15\,\mathrm{ab}^{-1}$ of data. We estimate the reach for various Lorentz and QCD color representations of $\mathcal{Q}$. Identifying the nature of $\mathcal{Q}$ is very important to understanding the physics behind the monojet signature. Therefore, we also study the dependence of the observables built from the $pp\to\mathcal{Q}\bar{\mathcal{Q}} + j $ process on $\mathcal{Q}$ itself. Using the state-of-the-art Monte Carlo suites MadGraph5_aMC@NLO+Pythia8 and Sherpa, we find that when these observables are calculated at NLO in QCD with parton shower matching and multijet merging, the residual theoretical uncertainties are comparable to differences observed when varying the quantum numbers of $\mathcal{Q}$ itself. We find, however, that the precision achievable with NNLO calculations, where available, can resolve this dilemma.

Structural, surface and electrochemical studies of LaNbO4 based ionic conductors
Creators: name: Li, Cheng
Publisher: name: Imperial College London
Year: 2016

description: In the search for novel solid oxide fuel cell (SOFC) electrolytes, research focus has shifted from conventional materials with high symmetry fluorite and perovskite structures, to those structures with anisotropic conducting paths and defective local environment. Amongst the novel fast ion conductors are the hyperstoichiometric modulated CeNbO4+d phases, which have displayed remarkably oxygen diffusivity in the intermediate temperature region (500 °C to 750 °C). The oxidation of Ce3+ to Ce4+, however, leads to undesirable electronic conduction. In addition, the structure and conducting mechanism of the modulated fergusonite phases has been left unexplored due to the structural modulation. This work thus aims to investigate the crystal structure, phase evolution and transport properties of LaNb1-xWxO4+d, a structural analogue to CeNbO4.25. The hyperstoichiometric LaNb1-xWxO4+d phases (x = 0.08–0.16) adopt a (3 + 2)D modulated structure, with cation ordering at the Nb/W site. Using the superspace group I2/c(α1,0,γ1)00(α2,0,γ2)00, the room temperature crystal structure of LaNb0.88W0.12O4+d has been refined using the Rietveld method with powder synchrotron diffraction data. The refined structure model suggests extended B-site coordination numbers, ranging from 6 to 8 with a 3Å cut-off. The additional B-O bonds accommodate the variations in local environment and provide linkages between the NbOx slabs, forming a 3D network similar to that in CeNbO4.25. In situ neutron diffraction has revealed a sequence of structural transformations which has been overlooked in the literature. Compared with the undoped LaNbO4, the conductivity of LaNb1-xWxO4+d phases is much improved, reaching 8 × 10-3 S cm-1 at 863 °C for LaNb0.88W0.12O4+d. 18O tracer diffusivity measurements have confirmed oxygen ions being the major charge carriers, and an interstitial conducting mechanism has been proposed to explain the improved conductivity. Despite the huge interest of utilising LaNbO4 based materials for SOFC electrolyte application, their surface chemistry, which plays an important role in determining electrochemical performance, has been left unexplored. Surface chemistry of acceptor doped LaNbO4 is investigated using LEIS and SIMS. A Nb and Sr enriched surface layer, approximately 6–7 nm thick, has been identified after annealing La0.99Sr0.01NbO4-d at 1000 °C. Isotopic exchange experiments reveal a systematic decrease in isotopic surface concentration after the Sr enriched layer has developed at the surface, highlighting the impact of surface chemistry on the ion transport process.
The search for novel histone lysine methyltransferase inhibitors

description: Reversal of aberrant epigenetic silencing by small molecule inhibitors is of high interest in the fields of chemical biology and drug discovery. Full understanding of these processes is crucial for the development of truly epigenetic therapies. Histone lysine methyltransferases (HKMTs), including G9a and EZH2, are the key players in epigenetic regulation, and are involved in many diseases such as cancer. In 2009, the first substrate competitive G9a inhibitor, BIX-01294, was reported by screening a large chemical library, which paved the way for future HKMT drug discovery research. In our research, we aimed to develop a novel substrate competitive dual G9a and EZH2 inhibitor using BIX-01294 as a prototype. Initially, the refinement of the side chain modification of BIX-01294 allowed us to understand essential Structure Activity Relationships (SAR) of the active compounds in a cell-based assay and an enzymatic assay (Chapter 2). Furthermore, the replacement of the quinazoline ring of BIX-01294 by other heteroaromatic rings was investigated (Chapter 3). While maintaining similar side chains as thosed use within the active compounds, new analogues including thieno-pyrimidine, furo-pyrimidine, purine and quinolone rings, were synthesised. Together these efforts have resulted in new synthetic routes towards a range of di-substituted heteroaromatic analogues as well as novel quinazoline derivatives for biological assessment. Compound 35, 158, and 183 show inhibitory activities against EZH2 in the enzymatic assay and promising SAR for further optimisation. Quinoline 183 also inhibits G9a in the low nanomolar range. Several compounds show promising data in the cell-based assay. Further biological evaluation of novel heteroaromatic analogues is currently underway.
Developing biomechanical models for the lymphatic valve
Creators: name: Wilson, John Tyler
Publisher: name: Imperial College London
Year: 2016

description: Along with playing a vital role in immune processes, the lymphatic system is a vascular network that transports extravasated fluid from the interstitial spaces to the venous return and helps maintain fluid homeostasis within the body. Its dysfunction can result in lymphoedema, or swelling of fluid within the interstitial spaces due to lymphatic impairment. There is a clear and present lack of knowledge of the pumping and transport mechanisms of the lymphatics. If physicians and scientists had a better understanding of these, more effective treatments for lymphoedema and other diseases of the lymphatic system could be derived. Bi-leaflet valves are frequent throughout the lymphatic vessels and serve to prevent retrograde flow. These valves play a vital role in fluid transport and pumping within the lymphatic system, however they have been largely understudied. Through a series of computational studies, the transport of nitric oxide (NO) within the lymphatic valve, the geometrical effect of the leaflets on the valve fluid dynamics and the interaction between the leaflets and lymphatic fluid have been studied. Computational investigations of NO transport indicated high levels of NO within the valve region as a result of flow stagnation. While the valves serve to prevent retrograde flow, they also add resistance, which is balanced out by the expansion of the bulbous sinus that encapsulates the leaflets. Consistent with experimental findings, the valve showed hysteretic opening and closing resistance values. These results strongly suggest the vital role of the valve within the lymphatic network of vessels. The research documented herein is the first recorded series of three-dimensional computational studies of flow and transport within the lymphatic valve and significantly contributes to the body of knowledge of the lymphatic vasculature.

description: We present a stability analysis of the standard nonautonomous systems type for a recently introduced generalized Lane-Emden equation which is shown to explain the presence of some of the structures observed in the atomic spatial distributions of magnetically-trapped ultracold atomic clouds. A Lyapunov function is defined which helps us to prove that stable spatial structures in the atomic clouds exist only for the adiabatic index $γ=1+1/n$ with even $n$. In the case when $n$ is odd we provide an instability result indicating the divergence of the density function for the atoms. Several numerical solutions, which according to our stability analysis are stable, are also presented.
