description: We investigate the collisional stability of a sample of 40K atoms immersed in a tunable spin mixture of 6Li atoms. In this three-component Fermi-Fermi mixture, we find very low loss rates in a wide range of interactions as long as molecule formation of 6Li is avoided. The stable fermionic mixture with two resonantly interacting spin states of one species together with another species is a promising system for a broad variety of phenomena in few- and many-body quantum physics.

description: We use two independent methods to forecast the dark energy measurements achievable by combining future galaxy redshift surveys based on the radio HI emission line with Cosmic Microwave Background (CMB) data from the {\sl Planck} satellite. In the first method we focus on the `standard ruler' provided by the baryon acoustic oscillation (BAO) length scale. In the second method we utilize additional information encoded in the galaxy power spectrum including galaxy bias from velocity-space distortions and the growth of cosmic structure. We find that a radio synthesis array with about 10 per cent of the collecting area of the Square Kilometre Array (SKA), equipped with a wide ($10-100 ~ {\rm deg}^2$) field-of-view, would have the capacity to perform a $20{,}000 ~ {\rm deg}^2$ redshift survey to a maximum redshift $z_{\rm max} \sim 0.8$ and thereby produce dark energy measurements that are competitive with surveys likely to be undertaken by optical telescopes around 2015. There would then be powerful arguments for adding collecting area to such a `Phase-1' SKA because of the square-law scaling of survey speed with telescope sensitivity for HI surveys, compared to the linear scaling for optical redshift surveys. The full SKA telescope should, by performing a $20{,}000 ~ {\rm deg}^2$ HI redshift survey to $z_{\rm max} \sim 2$ around 2020, yield an accurate measurement of cosmological parameters independent of CMB datasets. Combining CMB ({\sl Planck}) and galaxy power spectrum (SKA) measurements will drive errors in the dark energy equation-of-state parameter $w$ well below the 1 per cent level. The major systematic uncertainty in these forecasts is the lack of direct information about the mass function of high-redshift HI-emitting galaxies.

description: Single scale quantities, as anomalous dimensions and hard scattering cross sections, in renormalizable Quantum Field Theories are found to obey difference equations of finite order in Mellin space. It is often easier to calculate fixed moments for these quantities compared to a direct attempt to derive them in terms of harmonic sums and their generalizations involving the Mellin parameter $N$. Starting from a sufficiently large number of given moments, we establish linear recurrence relations of lowest possible order with polynomial coefficients of usually high degree. Then these recurrence equations are solved in terms of d'Alembertian solutions where the involved nested sums are represented in optimal nested depth. Given this representation, it is then an easy task to express the result in terms of harmonic sums. In this process we compactify the result such that no algebraic relations occur among the sums involved. We demonstrate the method for the QCD unpolarized anomalous dimensions and massless Wilson coefficients to 3--loop order treating the contributions for individual color coefficients. For the most complicated subproblem 5114 moments were needed in order to produce a recurrence of order 35 whose coefficients have degrees up to 938. About four months of CPU time were needed to establish and solve the recurrences for the anomalous dimensions and Wilson coefficients on a 2 GHz machine requiring less than 10 GB of memory. No algorithm is known yet to provide such a high number of moments for 3--loop quantities. Yet the method presented shows that it is possible to establish and solve recurrences of rather large order and and degree, occurring in physics problems, uniquely, fast and reliably with computer algebra.

description: Respiration in bacteria involves a sequence of energetically-coupled electron and proton transfers creating an electrochemical gradient of protons (a proton-motive force) across the inner bacterial membrane. With a simple kinetic model we analyze a redox loop mechanism of proton-motive force generation mediated by a molecular shuttle diffusing inside the membrane. This model, which includes six electron-binding and two proton-binding sites, reflects the main features of nitrate respiration in E. coli bacteria. We describe the time evolution of the proton translocation process. We find that the electron-proton electrostatic coupling on the shuttle plays a significant role in the process of energy conversion between electron and proton components. We determine the conditions where the redox loop mechanism is able to translocate protons against the transmembrane voltage gradient above 200 mV with a thermodynamic efficiency of about 37%, in the physiologically important range of temperatures from 250 to 350 K.

description: One of the primary objectives of the New Zealand Earth System Model (NZESM) is to reduce shortwave radiation biases over the Southern Ocean, which are related to deficiencies in representation of clouds and aerosols in this region. This is a subject of active research with multiple hypotheses being tested including cloud microphysics, cloud–aerosol interaction, horizontal homogeneity and differences in the frequency of cloud regimes related to different weather systems being examined. Comparison with observations is necessary for the identification and resolution of these deficiencies. Unfortunately, observations in the Southern Ocean are scarce, with satellites providing the most extensive spatial and temporal coverage, especially instruments such as MODIS and ISCCP and active instruments such as radar and lidar (laser lidar) on the CloudSat and CALIPSO satellites. However, these instruments lack the capability to observe low-level cloud when there is a higher-level overlapping cloud.

We present a multi-year dataset of shipborne and ground-based ceilometer, radar and aerosol observations in the Southern Ocean, which allows for cloud to be seen ‘from below’. In particular, we discuss the use the Cloud Feedback Model Intercomparison Project (CFMIP) Observation Simulator Package (COSP) to compare the ceilometer measurements with NZESM simulations. The COSP simulator currently does not support ground-based lidars with a matching wavelength, but the ACTSIM lidar simulator in COSP requires only a few modifications to support the analysis of ceilometer data. Using an instrument simulator such as COSP allows us to account for the limited view of the ceilometer and signal attenuation in the atmosphere.

We apply the newly developed ceilometer simulator to the NZESM atmospheric state output in the regions of the Southern Ocean where shipborne or ground-based observations are available, and compare the resulting backscatter distribution and algorithmically derived products such as cloud base between the model and observations.

Revisitando a linguagem mística: um contributo para um estudo sobre a natureza da sua identificação

description: The mystical language revisited: a contribution to the study of the nature of its identification. In this concise and programmatic essay – for further studies on the nature of the mystic language –, after a brief introduction on its objective – and an even more succinct reference to the common understanding of what is “mystic” and “language” –, the author makes an auxiliary mention to the typical elements that are recognized as essentials to “mystical language”. Then – in his more original contribution – he formulates an axiom, or hypothesis, which considers that “mystic language” has – as a proper intrinsic characteristic of its most nuclear nature – the virtue to be recognized as such because it communicates, somehow, a kind of “peak-experience” which – while establishing the reader in a mystagogical itinerary – allows him to identify previously unnoticed divine’s communications and, as a result of that, realize – due to a new “conceptual kit” – that what he has been reading, or rereading, is a typical way of translating, and shaping, those ineffable experiences.

description: As hydrogen is a renewable energy source, the studies for materials exhibiting fast hydrogen transport can have great potential to be used as electrolytes for electrochemical devices and as strong reducing agents for electrochemical conversion reactions. The alkaline earth metals, AeH₂, where Ae = Ca, Sr and Ba are of interest as they exhibit fast hydride ion conductivity which may enable them to be used as solid-state electrolytes in electrochemical devices. BaH₂ has a high hydride ion conductivity of 0.2 S cm⁻¹ at 630 °C, which is an order of magnitude higher than other oxide ion conductors at a similar temperature. The in-situ PDF and conductivity study of BaD₂ was performed to examine the local deviation from the average crystal structure. The technique using neutron total scattering helped to examine possible short-range correlations between atoms to understand the local structure of BaD₂. BaH₂ was doped with the monovalent ions Na or Li and its structural and electrical properties, were investigated. LiₓBa₁₋ₓH₂₋ₓ (x = 0.05, 0.10, 0.15 and 0.20) were synthesised by the solid-state reaction in which Li₀.₁₀Ba₀.₉₀H₁.₉₀ has achieved highest conductivity of 0.38 S cm⁻¹ at 600 °C. LiBaH₃ was synthesised by mechanochemical reaction at room temperature and solid-state reaction at high temperature, and their structural and electrical properties were analysed. LiBaH₃ has a conductivity of 0.01 S cm⁻¹ at 600 °C. NaₓLi₁₋ₓBaH₃ (x = 0.05, 0.15 and 0.20) were also synthesised by solid-state reaction and their structural and electrical properties were examined. Na₀.₁₅Li₀.₈₅BaH₃ has the highest conductivity of the Na-doped LiBaH₃ samples studied, exhibiting a conductivity of 0.03 S cm⁻¹ at 600 °C. Nitridation in LiₓBa₁₋ₓH₂₋ₓ (x = 0.05, 0.10, 0.15 and 0.20), NaₓBa₁₋ₓH₂₋ₓ (x = 0.01, 0.05 and 0.10), LiBaH₃ and NaₓLi₁₋ₓBaH₃ (x = 0.05, 0.15 and 0.20) increases their conductivity by 0.02 S cm⁻¹ initially due to exothermic reaction, except the nitridation of BaH₂ at 600 °C, where their conductivity decreases by 0.04 S cm⁻¹ upon nitridation due to endothermic reaction.

title: A sea of islands: tropes of travel and adventure in the Pacific 1846-1894
Creators: name: Rigby, Nigel
Publisher: name: University of Kent
Year: 2021

description: This thesis is concerned with images of the South Pacific that were built up in a variety of travel books and adventure stories in the second half of the nineteenth century. The thesis will read this literature alongside the explorer, castaway and missionary narratives that formed the body of Pacific writing up to the 1850s. It will argue that these images are informed by a set of recognisable tropes and narrative traditions, which the thesis will identify through imperial narratives from outside the Pacific. It will discuss the degree to which these tropes continued to dominate representation of the Pacific. Chapter 2 will examine the influence of images of the American Indians through Herman Melville's Typee. Secondary texts used are William Mariner's An Account of the Natives of the Tonga Islands, George Vason's An Authentic Narrative of Four Years' Residence at Tongataboo, and Puritan captivity narratives from New England. Chapter 3 discusses Polynesian sexuality and 'interracial' relationships through Pierre Loti's Tahiti: The Marriage of Loti, representations of the Mutiny on the Bounty and an imperial tradition of sentimental love stories. This chapter is also interested in links between images of the Orient and the Pacific. Chapter 4 looks at the children's adventure story writer, W.H.G. Kingston, alongside missionary and travel writing from Fiji, and is particularly interested in images of slavery and Africa, and the altering meaning of savagery in mid-Victorian Britain. Chapter 5 looks first at the writings of Charles Warren Stoddard, and then at the travel writing and adventure stories of Robert Louis Stevenson, and will explore the differences between the two types of writing, as Stevenson began to seriously challenge in his fiction the tropes that were dominating representations of the Pacific. This chapter will question whether it is ever fully possible to free oneself from these narrative traditions.

The relationship between separating sets and the geometry of the metric tangent cone of Bernig and Lytchak is described. Moreover, separating sets are used to show that the inner Lipschitz type need not be constant in a family of normal complex surface germs of constant topology.

description: Increasingly flexible and dynamic network infrastructures, due to softwarization, virtualization and increasing mobility (5G and 6G networks), challenge network management. To cope with the increasing dynamics and complexity, recent research focuses on autonomic network management solutions that do not require human intervention. However, autonomic network management solutions often require up-to-date topological information during network bootstrapping or to quickly react to dynamic events. Therefore, a fast, efficient, and scalable link-layer topology discovery, providing autonomic network management solutions with topological information in highly dynamic and large-scale networks, is required. This paper introduces KeLLy an efficient, scalable link layer topology discovery algorithm for large-scale networks (evaluated with up to 100 000 nodes). KeLLy is fast, discovering large topologies within a few seconds, guarantees discovery of all nodes and all links while inducing low, predictable overhead by querying only a subset (generally below 4 percent) of nodes. It achieves these properties regardless of the type of underlying topology.

description: Within the framework of an exact analytical solution of Maxwell equations in a space domain, it is shown that optical scheme based on a slab with negative refractive index ($n=-1$) (Veselago lens or Pendry lens) does not possess focusing properties in the usual sense . In fact, the energy in such systems does not go from object to its "image", but from object and its "image" to an intersection point inside a metamaterial layer, or vice versa. A possibility of applying this phenomenon to a creation of entangled states of two atoms is discussed.

description: In this paper, we introduce an approach to the protein folding problem from the point of view of statistical physics. Protein folding is a stochastic process by which a polypeptide folds into its characteristic and functional 3D structure from random coil. The process involves an intricate interplay between global geometry and local structure, and each protein seems to present special problems. We introduce CSAW (conditioned self-avoiding walk), a model of protein folding that combines the features of self-avoiding walk (SAW) and the Monte Carlo method. In this model, the unfolded protein chain is treated as a random coil described by SAW. Folding is induced by hydrophobic forces and other interactions, such as hydrogen bonding, which can be taken into account by imposing conditions on SAW. Conceptually, the mathematical basis is a generalized Langevin equation. To illustrate the flexibility and capabilities of the model, we consider several examples, including helix formation, elastic properties, and the transition in the folding of myoglobin. From the CSAW simulation and physical arguments, we find a universal elastic energy for proteins, which depends only on the radius of gyration $R_{g}$ and the residue number $N$. The elastic energy gives rise to scaling laws $R_{g}\sim N^ν$ in different regions with exponents $ν=3/5,3/7,2/5$, consistent with the observed unfolded stage, pre-globule, and molten globule, respectively. These results indicate that CSAW can serve as a theoretical laboratory to study universal principles in protein folding.

Production of a well collimated neutron beam using the associated particle technique
Creators: name: Tripard, Gerald Edward
Publisher: name: University of British Columbia
Year: 2011

description: An accurately colliraated monenergetic fast neutron beam of small angular width was produced by bombarding a deuterium target with 2 MeV deuterons. Background reduction was achieved by using the associated particle technique and extensive shielding. Dual parameter pulse height analysis was used to reduce the coincidence time resolution between the detected neutrons and the associated He³ recoil particle to 4.6 nanoseconds by taking into account the variations in flight times of the He³ particles. A rotating thin film deuterated polyethylene target was developed which enabled a substantial increase in the neutron flux to be made. The beam of 70 neutrons/second/millisteradian produced, was of sufficient intensity to perform a small angle scattering experiment. The technique was tested by a measurement of the angular distribution from 40 degrees to 10 degrees of neutrons elastically scattered from lead.

description: Higgs boson and massive-graviton productions in association with two jets via vector-boson fusion (VBF) processes and their decays into a vector-boson pair at hadron colliders are studied. They include scalar and tensor boson production processes via weak-boson fusion in quark-quark collisions, gluon fusion in quark-quark, quark-gluon and gluon-gluon collisions, as well as their decays into a pair of weak bosons or virtual gluons which subsequently decay into $\ell\bar\ell$, $q\bar q$ or $gg$. We give the helicity amplitudes explicitly for all the VBF subprocesses, and show that the VBF amplitudes dominate the exact matrix elements not only for the weak-boson fusion processes but also for all the gluon fusion processes when appropriate selection cuts are applied, such as a large rapidity separation between two jets and a slicing cut for the transverse momenta of the jets. We also show that our off-shell vector-boson current amplitudes reduce to the standard quark and gluon splitting amplitudes with appropriate gluon-polarization phases in the collinear limit. Nontrivial azimuthal angle correlations of the jets in the production and in the decay of massive spin-0 and -2 bosons are manifestly expressed as the quantum interference among different helicity states of the intermediate vector-bosons. Those correlations reflect the spin and the CP nature of the Higgs bosons and the massive gravitons.

description: This Policy Brief outlines the inception and proposed structure of the Health Research and Innovation Cloud (HRIC), stemming from a 2018 European Commission initiative aimed at addressing challenges in health research developed in the HealthyCloud Coordination and Support Action. The document emphasizes the vision of coordination over the creation of new infrastructures. The HRIC is envisioned as a federated organization utilizing existing European structures to provide specialised services for research, innovation, and policy-making using health-related data. It identifies five key services, ranging from monitoring research landscapes to facilitating interactions with initiatives like the European Open Science Cloud (EOSC) and the European Health Data Space (EHDS). These services cater to diverse stakeholders, including researchers, policymakers, and funders, with a focus on promoting effective health data use and re-use, interoperability and FAIR adoption, legal compliance, and integration with major European health data initiatives. The document advocates an incremental implementation approach to gauge requirements, pilot services, and ensure sustainability. Ultimately, HRIC aims to navigate the evolving European health data landscape to support research, innovation, and policymaking endeavors.

Polarization of electron impact light from helium
Creators: name: Whitteker, James Howard
Publisher: name: University of British Columbia
Year: 2011

description: The polarization of light from helium atoms excited by the impact of low energy electrons has been measured for the spectral lines 2³P - 2³S (10,829 Å) and 3³P - 2³S (3889 Å). An electron beam carrying a current of 10μA was directed into helium gas at a pressure of 4 x 10⁻³ torr or less. Polarization was measured as a function of electron energy in a range from the excitation threshold (approximately 23 electron volts) to 50 e.v. For the 2³T - 2³S line, this work represents the first reported measurement of this type. There is special interest in the value of polarization near the excitation threshold. The theoretical threshold polarization for both lines studied in this thesis is 36.6%. In the experiment of this thesis, the observed polarization of the 2³P line rises to 21% near threshold, and by means of a curve fitting procedure may be extrapolated to 32 ± 6%. The polarization of the 3³P - 2³S line rises to 11% and may be extrapolated to 15 ± 3%.

description: Agricultural pests cause huge loss to agricultural production. Their control using biopesticides is gaining importance. Entomopathogenic nematodes (EPNs) are most promising biopesticides in agriculture. EPN like other biopesticides has a very specific action on one species or related species as against chemical insecticides. In addition, the median lethal time for EPNs is also lower. Hence there is a need for novel virulent EPN which is effective against wide range of insects and has a low median lethal dose. In this study, we isolated different strains of EPN using modified insect bait method from 10 different soil samples. Six nematode strains were isolated and tested for pathogenicity against Spodoptera litura egg, larvae, and pupae. Agricultural corn field (AC) strain showed very high virulence against other strains. AC strain 18S rDNA sequencing was done and phylogenetic tree constructed to evaluate its relatedness to other species. The AC strains were identified as Panagrolaimus spp. and the sequence was submitted to Genbank. This species was found to be very effective against all the developmental stages of S. litura

description: Dichroplus maculipennis is one of the most damaging grasshoppers of wetlands. We investigated their feeding behavior in relation to the most abundant plants of Patagonian wetlands. Results showed that D. maculipennis was able to select its food resources and displayed a mixed diet. The most consumed plant was Taraxacum officinale, which contains a large amount of protein and water. However, consumption decreased when offered simultaneously with Juncus balticus and Holcus lanatus. Therefore, diet varied according to the supply of plants that were offered. In future studies, it would be interesting to analyze the influence of diet on performance.

description: The exclusive ability of acoustic waves to probe the structural, mechanical and fluidic properties of foams may offer novel approaches to characterise the porous scaffolds employed in tissue engineering. Motivated by this we conduct a preliminary investigation into the acoustic properties of a typical biopolymer and the feasibility of acoustic propagation within a foam scaffold thereof. Focussing on poly(lactic-co-glycolic acid), we use a pulse-echo method to determine the longitudinal speed of sound, whose temperature-dependence reveals the glass transition of the polymer. Finally, we demonstrate the first topographic and tomographic acoustic images of polymer foam tissue scaffolds.

description: We study spin accumulation and spin transfer torque in a domain wall by solving the Boltzmann equation with a diffusion approximation. We obtained the analytical expressions of spin accumulation and spin transfer torque. Both the adiabatic and the non-adiabatic components of the spin transfer torque oscillate with the thickness of the domain wall. We show that the oscillation plays a dominant role in the non-adiabatic torque when the domain wall thickness is less than the spin-flip length, which is defined by the product of the Fermi velocity and the spin-flip scattering time.

description: Als Sammlung eines Museums nehmen Museumsbibliotheken in der bibliotheks- und informationswissenschaftlichen Landschaft eine besondere Stellung mit dualer Funktion ein. Ihre Bestände dienen in der Regel nicht nur als Informationsträger für die wissenschaftliche Arbeit im Museum, sondern werden auch als potentielle Ausstellungsobjekte betrachtet. Zu Letztgenannten gehören u.a. wertvolle Altbestände, wie etwa Inkunabeln. Da Bibliotheken und Museen ihre Sammlungen unterschiedlich erschließen, steht der Vergleich zwischen bibliothekarischer Erschließung in einem Online-Katalog und musealer Dokumentation in einer Objektdatenbank von Inkunabeln im Zentrum der vorliegenden Arbeit. Hierfür werden eingangs die Erschließungskomponenten von Inkunabeln benannt, die Erschließungsvarianten in Bibliotheken und Museen dargelegt sowie wichtige Inkunabelverzeichnisse vorgestellt. Anhand von acht Beispielbibliotheken wird stellvertretend gezeigt, wie Museumsbibliotheken heute ihre Inkunabelbestände präsentieren. Ziel des darauffolgenden Vergleichs von Inkunabeln in Online-Katalogen und Museumsdatenbanken ist es darzustellen, wie man in hybriden Einrichtungen wie Museumsbibliotheken beide Methoden harmonisch miteinander verbinden kann, um die Sammlungen bestmöglich zu erschließen. Zuletzt wird illustriert, wofür die durch die Erschließung gewonnenen Metadaten beider Verfahren weitergenutzt werden können.
Symmetry-break, mixing, instability, and low frequency variability in a minimal Lorenz-like system

description: Starting from the classical Saltzman 2D convection equations, we derive via a severe spectral truncation a minimal 10 ODE system which includes the thermal effect of viscous dissipation. Neglecting this process leads to a dynamical system which includes a decoupled (generalized) Lorenz system. The consideration of this process breaks an important symmetry, couples the dynamics of fast and slow variables, ensuing modifications of the structural properties of the attractor and of the spectral features. When the relevant nondimensional number (Eckert number Ec) is different from zero, the system is ergodic and hyperbolic, the slow variables feature long term memory with 1/f 3/2 power spectra, and the fast variables feature amplitude modulation on time scale of 1/Ec. Increasing the strength of the thermal-viscous feedback has a stabilizing effect, as both the metric entropy and the Kaplan-Yorke attractor dimension decrease monotonically with Ec. The analyzed system features very rich dynamics: it overcomes some of the limitations of the Lorenz system and might have prototypical value in relevant processes in complex systems dynamics, such as the interaction between slow and fast variables. the presence of long term memory and the associated extreme value statistics. Analysis shows how, neglecting the coupling of slow and fast variables only on the basis of scale analysis can be catastrophic. In fact, this leads to spurious invariances that affect essential dynamical properties (ergodicity, hyperbolicity) and that cause the model losing ability in describing intrinsically multiscale processes.

description: Conformal many-body mechanics in Newton-Hooke spacetime is studied within the framework of the Lagrangian formalism. Global symmetries and Noether charges are given in a form convenient for analyzing the flat space limit. N=2 superconformal extension is built and a new class on N=2 models related to simple Lie algebras is presented. A decoupling similarity transformation on N=2 quantum mechanics in Newton-Hooke spacetime is discussed.

description: Single-scale quantities, like the QCD anomalous dimensions and Wilson coefficients, obey difference equations. Therefore their analytic form can be determined from a finite number of moments. We demonstrate this in an explicit calculation by establishing and solving large scale recursions by means of computer algebra for the anomalous dimensions and Wilson coefficients in unpolarized deeply inelastic scattering from their Mellin moments to 3-loop order.

The nature of pulsar radio emission

description: High-quality averaged radio profiles of some pulsars exhibit double, highly symmetric features both in emission and absorption. It is shown that both types of features are produced by a split-fan beam of extraordinary-mode curvature radiation (CR) that is emitted/absorbed by radially-extended streams of magnetospheric plasma. With no emissivity in the plane of the stream, such a beam produces bifurcated emission components (BFCs) when our line of sight passes through the plane. A distinct example of double component created in that way is present in averaged profile of the 5 ms pulsar J1012+5307. We show that the component can indeed be very well fitted by the textbook formula for the non-coherent beam of curvature radiation in the polarisation state that is orthogonal to the plane of electron trajectory. The observed width of the BFC decreases with increasing frequency at the rate that confirms the curvature origin. Likewise, the double absorption features (double notches) are produced by the same beam of the extraordinary-mode CR, when it is eclipsed by thin plasma streams. The intrinsic property of CR to create bifurcated fan beams explains the double features in terms of very natural geometry and implies the curvature origin of pulsar radio emission. (abbreviated)
