description: Based on a discussion of the theory experiment connection, it is proposed to tighten the connection by replacing the real and complex number basis of physical theories by sets R_{n},C_{n} of length 2n finite binary string numbers. The form of the numbers in R_{n} is based on the infinite hierarchy of 2n figure outputs from measurements of any physical quantity with an infinite range (distance, energy, etc.). A space and time based on these numbers is described. It corresponds to an infinite sequence of spherical scale sections R_{n,e} (e an integer). Each section has the same number of points but the size increases exponentially with increasing e. The sections converge towards an origin which is a space singularity. Iteration of an order preserving transformation, F_{>n_{0}. Here n_{I} is such that the outermost Δscale sections of R_{n_{0}} space, which are moving at velocities >c at time t_{I}, are contained in the scale section R_{n_{I},0} of R_{n_{I}} space. This is needed if R_{n_{I},0} space is to be similar to the usual R space. Hubble expansion and the redshift are accounted for by a continuing slow increase in n. Comparison with experimental data suggests that the rate of increase must be at least one n unit every 30-60 million years.

description: X-ray absorption near-edge spectroscopy (XANES) is used to study the N environment in bulk GaN and in GaN{y}As{1-y} epilayers on GaAs (001), for y \~5%. Density-functional optimized structures were used to predict XANES via multiple-scattering theory. We obtain striking agreement for pure GaN. An alloy model with nitrogen pairs on Ga accurately predicts the threshold energy, the width of the XANES ``white line'', and features above threshold, for the given X-ray polarization. The presence of N-pairs may point to a role for molecular N_2 in epitaxial growth kinetics.

description: Los cambios medioambientales globales hacen pensar en un aumento futuro de la aridez, por ello es necesario buscar alternativas que permitan un uso más eficiente del agua y reducir su consumo, teniendo en cuenta que es un recurso limitado. En la actualidad, aproximadamente el 59,7% del total de agua planificada para todos los usos en Cuba se utiliza en la agricultura, pero no más del 50% de esa agua se convierte directamente en productos agrícolas. El estudio de las funciones agua-rendimiento y su uso dentro de la planificación del agua para riego es una vía importante para trazar estrategias de manejo que contribuyan al incremento en la producción agrícola. Utilizando los datos de agua aplicada por riego y los rendimientos obtenidos en más de 100 experimentos de campo realizados fundamentalmente en suelo Ferralítico Rojo de la zona sur de La Habana y con ayuda de herramientas de análisis de regresión en este trabajo se estiman las funciones agua aplicada-rendimientos para algunos cultivos agrícolas y se analizan las posibles estrategias de optimización del riego a seguir en función de la disponibilidad de agua. Seleccionar una estrategia de máxima eficiencia del riego puede conducir a reducciones de agua a aplicar entre un 21,6 y 46,8%, incrementos de la productividad del agua entre 17 y 32% y de la relación beneficios/costo estimada de hasta un 3,4%. Lo anterior indica la importancia desde el punto de vista económico que puede llegar a alcanzar el uso de esta estrategia en condiciones de déficit hídrico. El conocimiento de las funciones agua aplicada por riego-rendimiento y el uso de la productividad del agua, resultan parámetros factibles de introducir como indicadores de eficiencia en el planeamiento del uso del agua en la agricultura, con lo cual es posible reducir los volúmenes de agua a aplicar y elevar la relación beneficio-costo actual.

description: We introduce the generalized spatial discretization of the Kardar-Parisi-Zhang (KPZ) equation in 1+1 dimensions. We solve exactly the steady state probability density function for the discrete heights of the interface, for any discretization scheme. We show that the discretization prescription is a consequence of each particular model. From the ballistic deposition model we derive the discretization prescription of the corresponding KPZ equation.

description: We study the optical linear and circular polarisation in the optically-thin regime of the core and jet of M87. Observations were acquired two days before the Event Horizon Telescope (EHT) campaign in early April 2017. A high degree ($\sim 20$ per cent) of linear polarisation (P$_{\rm lin}$) is detected in the bright jet knots resolved at $\sim 10\, \rm{arcsec}$ to $23\, \rm{arcsec}$ ($0.8$-$1.8\, \rm{kpc}$) from the centre, whereas the nucleus and inner jet show P$_{\rm lin} \lesssim 5$ per cent. The position angle of the linear polarisation shifts by $\sim 90$ degrees from each knot to the adjacent ones, with the core angle perpendicular to the first knot. The nucleus was in a low level of activity (P$_{\rm lin} \sim 2$-$3$ per cent), and no emission was detected from HST-1. No circular polarisation was detected either in the nucleus or the jet above a $3σ$ level of P$_{\rm circ} \leq 1.5$ per cent, discarding the conversion of P$_{\rm lin}$ into P$_{\rm circ}$. A disordered magnetic field configuration or a mix of unresolved knots polarised along axes with different orientations could explain the low P$_{\rm lin}$. The latter implies a smaller size of the core knots, in line with current interferometric observations. Polarimetry with EHT can probe this scenario in the future. A steep increase of both P$_{\rm lin}$ and P$_{\rm circ}$ with increasing frequency is expected for the optically-thin domain, above the turnover point. This work describes the methodology to recover the four Stokes parameters using a $λ/4$ wave-plate polarimeter.

description: Asymmetric muscle strength can influence dynamic movement in a variety of tasks and across the lifespan. While asymmetric muscle strength can occur from continuous and repeated use, most studies focus on single rep, maximal effort tasks, often with high-performing athletes. Comparing tasks of varying difficulty may help characterize muscular and movement asymmetry. Net joint moments are useful to determine mechanical requirements of dynamic tasks and are largely a result of muscle strength. Therefore, this study aimed to compare lower limb joint moments between legs for single-leg and double-leg hopping tasks in young, healthy individuals. Nine participants (4M/5F, 22.1yrs ± 3.2yrs, 1.73m ± 0.09m, 66.98kg ± 11.94kg) completed a baseline double-leg hopping task and bilateral single-leg hopping tasks. Kinetic (2000hz) and full-body kinematic (200hz) data were collected at self-selected frequency, averaging 11.11 and 8.11 cycles over 15 seconds for double-leg and single-leg tasks, respectively. Each cycle was defined from ground contact to subsequent ground contact. A 12-segment dynamic model was used to compute sagittal-plane joint moments at the hip, knee and ankle. A paired t-test revealed a significant difference between legs in bilateral peak hip joint moment during double-leg hopping (p=0.015), but there were no differences between legs at the knee or ankle, or during single-leg hopping. F-tests found no difference in peak moment variance between legs for any joint for either task. These findings indicate symmetric joint moment variation and magnitude for tasks of differing mechanical demands in young, healthy participants. Future work will evaluate a broader population.

description: Im Rahmen einer Verbundstudie wurden in 14 deutschen Dörfern die Beziehungen zwischen Landwirtschaft und den Untersuchungsdörfern im Hinblick auf den Wirtschaftsstandort, die Wohn- und Erholungsfunktion, sowie die soziale Kohäsion auf ihre Wechselwirkungen hin exemplarisch evaluiert. Die Ergebnisse zeigen, dass sich der Charakter der Untersuchungsdörfer als ländliche Orte weiter von der Landwirtschaft löst. Die direkte Erfahrung von Landwirtschaft nimmt aufgrund von Betriebsaufgaben und geringerer Nähe der Nichtlandwirte zur Landwirtschaft und zur landwirtschaftlichen Bevölkerung ab. In Bezug auf Landschaftspflege, Landschaftserhalt und Umweltschutz können Landwirte besonders in landwirtschaftlichen Intensivregionen nicht allen Anforderungen der Nichtlandwirte gerecht werden. Landwirte reagieren mit unterschiedlichen Strategien auf die Anforderungen der Nichtlandwirte.

In der vorliegenden Arbeit werden dieser Ansatz auf den Kontext inter-organisationaler landwirtschaftlicher Geschäftsbeziehungen übertragen. Auf Basis einer umfassenden standardisierten Online-Erhebung unter Schweizer Bio-Landwirten wird die Wirkung von Fairness Wahrnehmungen der Landwirte auf Ergebnisse und Leistungen der Geschäftsbeziehung in einem PLS-Strukturgleichungsmodell analysiert. Das Modell kann ca. 60% der Varianz des Konstruktes Leistung der Geschäftsbeziehung erklären. In weiteren Analysen könnte der Einfluss moderierender Variablen (z.B. Dauer der Geschäftsbeziehung; Betriebsstruktur) untersucht werden.

description: We consider Wilson's SU(N) lattice gauge theory (without fermions) at negative values of beta= 2N/g^2 and for N=2 or 3. We show that in the limit beta -> -infinity, the path integral is dominated by configurations where links variables are set to a nontrivial element of the center on selected non intersecting lines. For N=2, these configurations can be characterized by a unique gauge invariant set of variables, while for N=3 a multiplicity growing with the volume as the number of configurations of an Ising model is observed. In general, there is a discontinuity in the average plaquette when g^2 changes its sign which prevents us from having a convergent series in g^2 for this quantity. For N=2, a change of variables relates the gauge invariant observables at positive and negative values of beta. For N=3, we derive an identity relating the observables at beta with those at beta rotated by +- 2pi/3 in the complex plane and show numerical evidence for a Ising like first order phase transition near beta=-22. We discuss the possibility of having lines of first order phase transitions ending at a second order phase transition in an extended bare parameter space.

description: We investigate unconventional superfluidity in a gas of Fermi atoms with an anisotropic p-wave Feshbach resonance. Including the p-wave Feshbach resonance as well as the associated three kinds of quasi-molecules with finite orbital angular momenta $L_z=\pm1,0$, we calculate the transition temperature of the superfluid phase. As one passes through the p-wave Feshbach resonance, we find the usual BCS-BEC crossover phenomenon. The p-wave BCS state continuously changes into the BEC of bound molecules with L=1. Our calculation includes the effect of fluctuations associated with Cooper-pairs and molecules which are not Bose-condensed.

description: The iterative method recently proposed for determining the internal constitution of the outer crust of a nonaccreted neutron star is extended to magnetars by taking into account the Landau-Rabi quantization of electron motion induced by the presence of a very high magnetic field. It is shown that in the strongly quantizing regime, the method can be efficiently implemented using new analytical solutions for the transitions between adjacent crustal layers. Detailed numerical computations are performed to assess the performance and precision of the method.

title: Balancing privacy needs with location sharing in mobile computing
Creators: name: Adam, Karim Anthony
Publisher: name: The Open University
Year: 2009

description: Mobile phones are increasingly becoming tools for social interaction. As more phones come equipped with location tracking capabilities, capable of collecting and distributing personal information (including location) of their users, user control of location information and privacy for that matter, has become an important research issue. This research first explores various techniques of user control of location in location-based systems, and proposes the re-conceptualisation of deception (defined here as the deliberate withholding of location information) from information systems security to the field of location privacy. Previous work in this area considers techniques such as anonymisation, encryption, cloaking and blurring, among others. Since mobile devices have become social tools, this thesis takes a different approach by empirically investigating first the likelihood of the use of the proposed technique (deception) in protecting location privacy. We present empirical results (based on an online study) that show that people are willing to deliberately withhold their location information to protect their location privacy. However, our study shows that people feel uneasy in engaging in this type of deception if they believe this will be detected by their intended recipients. The results also suggest that the technique is popular in situations where it is very difficult to detect that there has been a deliberate withholding of location information during a location disclosure. Our findings are then presented in the form of initial design guidelines for the design of deception to control location privacy. Based on these initial guidelines, we propose and build a deception-based privacy control model. Two different evaluation approaches are employed in investigating the suitability of the model. These include; a field-based study of the techniques employed in the model and a laboratory-based usability study of the Mobile Client application upon which the DPC model is based, using HCI (Human Computer Interaction) professionals. Finally, we present guidelines for the design of deception in location disclosure, and lessons learned from the two evaluation approaches. We also propose a unified privacy preference framework implemented on the application layer of the mobile platform as a future direction of this thesis.

description: The Earth's high energy gamma-ray emission is caused by cosmic ray interactions with the atmosphere. The EGRET detector on-board the CGRO satellite is only the second experiment (after SAS-2) to provide a suitable dataset for the comprehensive study of this emission. Approximately 60% of the EGRET dataset consist of gamma photons from the Earth. This conference contribution presents the first results from the first analysis project to tackle this large dataset. Ultimate purpose is to develop an analytical model of the Earth's emission for use in the GLAST project. The results obtained so far confirm the earlier results from SAS-2 and extend them in terms of statistical precision and angular resolution.

description: We compute the high frequency quasi-normal modes (QNM) for scalar perturbations of spherically symmetric single horizon black-holes in $(D+2)$-space-time dimensions with generic curvature singularities and having metrics of the form $ds^2 = ηx^p (dy^2-dx^2) + x^q dØ_D^2$ near the singularity $x=0$. The real part of the QN frequencies is shown to be proportional to $\log \le[ 1 + 2\cos \le(\p \le[ qD -2 \ri]/2 \ri) \ri]$ where the constant of proportionality is equal to the Hawking temperature for non-degenerate black-holes and inverse of horizon radius for degenerate black-holes. Apart from agreeing with the QN frequencies that have been computed earlier, our results imply that the horizon area spectrum for the general spherically symmetric black-holes is equispaced. Applying our results, we also find the QNM frequencies for extremal Reissner-Nordström and various stringy black-holes.

It is found that we can connect the resulting expression for a bivector formed with those fields, with the expression deduced from the Wigner transformation rules for spin-1 functions of massive particles. This mass parameter should be interpreted because the constancy of speed of light forbids the existence of the photon mass.

description: We show that the recently demonstrated technique for generating stationary pulses of light [Nature {\bf 426}, 638 (2003)] can be extended to localize optical pulses in all three spatial dimensions in a resonant atomic medium. This method can be used to dramatically enhance the nonlinear interaction between weak optical pulses. In particular, we show that an efficient Kerr-like interaction between two pulses can be implemented as a sequence of several purely linear optical processes. The resulting process may enable coherent interactions between single photon pulses.

description: We study on topological properties of global supply chain network in terms of degree distribution, hierarchical structure, and degree-degree correlation in the global supply chain network. The global supply chain data is constructed by collecting various company data from the web site of Standard & Poor's Capital IQ platform in 2018. The in- and out-degree distributions are characterized by a power law with in-degree exponent = 2.42 and out-degree exponent = 2.11. The clustering coefficient decays as power law with an exponent = 0.46. The nodal degree-degree correlation indicates the absence of assortativity. The Bow-tie structure of GWCC reveals that the OUT component is the largest and it consists 41.1% of total firms. The GSCC component comprises 16.4% of total firms. We observe that the firms in the upstream or downstream sides are mostly located a few steps away from the GSCC. Furthermore, we uncover the community structure of the network and characterize them according to their location and industry classification. We observe that the largest community consists of consumer discretionary sector mainly based in the US. These firms belong to the OUT component in the bow-tie structure of the global supply chain network. Finally, we confirm the validity for propositions S1 (short path length), S2 (power-law degree distribution), S3 (high clustering coefficient), S4 ("fit-gets-richer" growth mechanism), S5 (truncation of power-law degree distribution), and S7 (community structure with overlapping boundaries) in the global supply chain network.

description: The effect of Carbon isotope substitution on T_c in the intermetallic perovskite superconductor MgCNi_3 is reported. Four independent groups of samples were synthesized and characterized. The average T_c for the Carbon-12 samples was found to be 7.12(2) K and the average T_c for the Carbon-13 samples was found to be 6.82(2) K. The resulting carbon isotope effect coefficient is alfa_C = 0.54(3). This indicates that carbon-based phonons play a critical role in the presence of superconductivity in this compound.

title: The Mineralogy And Chemistry Of Micrometeorites
Creators: name: Graham, Giles Andrew
Publisher: name: The Open University

description: Prior to their retrieval from low Earth orbit (LEO), the individual solar cells that make up the 'V2' solar array panel from the Huhble Space Telescope (HST) were prone to hypervelocity (>5 km/s ) impact damage from micrometeoroids and space debris. The analysis of such passive collector surfaces allows sampling of micrometeoroids that have not undergone any terrestrial atmospheric alteration and better defines the population of space debris particles below the 1mm size range. Herein a new approach has been taken to try and identify the nature and origin of impact derived residues generated in the individual solar cells from the HST. A total of 25 solar cells were selected on the basis that they contained impact craters (100-1000μm diameter) rather than larger impact holes (1-3mm diameter), as preliminary studies indicated that they were more likely to retain impact residues. These were subsequently analysed using digitised hack-scattered electron imaging, coupled with digitised x-ray elemental mapping and micro-spot analysis to locate, identify and classify the residues. 29 impact craters were located on solar cells. In the analysis of the residues; 3 were identified residues as space debris in origin, 6 unclassified and 20 as micrometeoroid. The space debris derived residues were identified as remnants of a paint fragment, a stainless steel particle and a fragment of a printed circuit board. The micrometeoroid derived residues were sub-classified in terms of mineral chemistry, with apparent mafic- and phyllo- silicates being the dominant components, with minor iron-nickel metal and iron sulfides, suggesting a broadly chondritic origin. Fe-Ni rich residue was also identified that would appear to belong to a group of non-chondritic particles previously unrecognised. Possible refractory or Ca/Al rich inclusions from a primitive micrometeoroid were also observed as near intact Ca-rich fragments, the textures of the individual grains suggested that they were not merely terrestrial contamination. Laboratory impact studies, using a light-gas-gun to accelerate small fragments (125- 250μm) of known meteorite mineralogies up to 5km/s, and then impact them into solar cells have generated a suite of residues that are analogues of those observed from LEO studies. The silicate minerals generated residues that were intimately associated with the host melt glass. Metallic sulfides and metals generated surface and sub-surface immiscible droplets. Several craters also contained near-intact fragments of minerals. Overall. despite the small sample set examined. the observed dominance of micrometeoroid to space debris residue chemistry (correlating to particle size range of 8-80μm) corresponds well to the accepted flux models.

description: Da es bisher wenig Erfahrung beim mehrjährigen Anbau von Holzbiomasse gibt, werden die Wirtschaftlichkeit und die Risiken des Anbaus von Pappeln und Weiden im Kurzumtrieb sowie von Miscanthus auf Ackerflächen für eine ausgewählte Region Baden-Württembergs untersucht. Hierzu wird eine stochastische Risikoanalyse (Monte-Carlo-Methode) durchgeführt. Es zeigt sich, dass der Anbau von Miscanthus die höchste Annuität sowie die geringste Streuung aufweist und im Gegensatz zu Pappeln und Weiden gegenüber einer gängigen Fruchtfolge konkurrenzfähig ist. Hauptursachen für die geringere Varianz der Annuität von Miscanthus sind die geringere Streuung seiner Erträge und die häufigeren Ernten.

description: Das deutsche Fleischerhandwerk steht vor der großen Herausforderung, sich im Konkurrenz-kampf mit dem Lebensmitteleinzelhandel behaupten und dem negativen Entwicklungstrend in der Branche entgegenwirken zu müssen. Dieser Beitrag untersucht den Einfluss von soziode-mographischen Merkmalen und Verbrauchereinstellungen auf die Wahl der Betriebsform ‚Fleischerfachgeschäft‘ mittels einer multiplen Regressionsanalyse. Die Ergebnisse deuten darauf hin, dass insbesondere das ausgeprägte Informationsbedürfnis der Fleischereikunden, die große Bedeutung der regionalen Herkunft der Produkte und die Vorliebe für eigenes Ko-chen und das Zubereiten von Fleisch Ansatzpunkte zur Differenzierung im Wettbewerb bie-ten. Nur begrenzte Möglichkeiten zur Segmentierung der Zielgruppe bieten dagegen die sozi-odemographischen Merkmale, von denen nur die „Haushaltgröße“ und die „Wohnortgröße“ einen signifikanten Einfluss auf die Einkaufshäufigkeit in Fleischerfachgeschäften aufweisen.

description: About ten years after the financial crisis, the awareness of counterparty credit risk still influences derivatives markets in terms of pricing. This thesis presents the impact on pricing derivatives using different valuation curves. Especially, the correct discounting curve should be chosen corresponding to the funding costs of a financial institution and is not necessarily the same as the curve used to calculate forward rates. Furthermore, different curve construction approaches in a multi-curve world are introduced.

description: Die vorgestellte Untersuchung, die auf der aktuellen Sozioökonomischen Analyse für den ELER-Förderfonds der EU basiert, umfasst eine regional vergleichende Analyse des Strukturwandels in der Agrar- und Ernährungswirtschaft. Dieser hat sich im vergangenen Jahrzehnt in Deutschland wie auch in der EU insbesondere über eine weitere Abnahme der Zahl der landwirtschaftlichen Betriebe und eine Zunahme der durchschnittlichen Betriebsgrößen vollzogen. In der Ernährungswirtschaft erfolgte ebenfalls ein Wachstum der Betriebe, so etwa hinsichtlich der durchschnittlichen Jahresumsätze. Aus den Untersuchungsergebnissen zum Strukturwandel sollen im Rahmen des vorgestellten Posterbeitrags auch Überlegungen zur Marktmacht in der Agrarwirtschaft und in der Ernährungswirtschaft hergeleitet werden.

title: Multiwavelength behaviour of Cygnus X-3 and related objects
Creators: name: Fender, Robert P.
Publisher: name: The Open University
Year: 1996

description: I present a detailed study of the behaviour of the exotic X-ray binary Cygnus X-3 at radio, (sub)mm, infrared, red-optical and X-ray wavelengths. Further unusual properties of the system are unearthed and previously expounded models are refined by new observations. In order to address the broader picture, a multiwavelength comparison of Cygnus X-3 with other ‘radio-jet’ X-ray binaries is also undertaken. Infrared observations of Cyg X-3 at high time resolution reveal many rapid flare events superimposed upon the 4.8 hr (presumed) orbital motion. Photometry simultaneously in the H & K-bands allows strong constraints to be placed upon T & Nε for the flaring component. Dereddening of RI- J-H-K-L-L’ photometry places limits on the likely extinction to Cyg X-3 of 4.5 ≤ AJ ≤ 7.5 mag. Further infrared study, simultaneous with radio monitoring and observations with OSSE/GRO and the INT shed greater light on the source, including possible orbital colour changes and a longterm correlation between radio and infrared flux levels. Deep imaging of the field reveals many previously undiscovered infrared sources within a few arcsec of Cyg X-3. Simultaneous millimetre and radio observations of Cyg X-3 reveal anomalously strong mm fluxes. Interpreting this in terms of significant absorption of the cm fluxes during the passage outwards of the radio-emitting plasmons, strengthens the case for a dense stellar wind in the Cyg X-3 system. Further radio and sub(mm) observations of Cyg X-3 during outburst confirm previously observed phenomena such as quenched radio emission prior to outburst, and establish the importance of radiation loss mechanisms in the decay of radio plasmons ejected from the source. A model describing the qualitative behaviour of the source during outburst is presented.
On the chain-level intersection pairing for PL manifolds

description: Let M be a compact oriented PL manifold and let C_*M be its PL chain complex. The domain of the chain-level intersection pairing is a subcomplex G of C_*M\otimes C_*M. We prove that G is a "full" subcomplex, that is, the inclusion of G in C_*M \otimes C_*M is a quasi-isomorphism. An analogous result is true for the domain of the iterated intersection pairing. Using this, we show that the intersection pairing gives C_*M a structure of partially defined commutative DGA, which in particular implies that C_*M is canonically quasi-isomorphic to an E_\infty chain algebra. An erratum is attached which corrects sign errors pointed out by Greg Friedman.

description: The field of behavioural biometrics stands as an appealing alternative to more traditional biometric systems due to the ease of use from a user perspective and potential robustness to presentation attacks. This paper focuses its attention to a specific type of behavioural biometric utilising swipe dynamics, also referred to as touch gestures. In touch gesture authentication, a user swipes across the touchscreen of a mobile device to perform an authentication attempt. A key characteristic of touch gesture authentication and new behavioural biometrics in general is the lack of available data to train and validate models. From a machine learning perspective, this presents the classic curse of dimensionality problem and the methodology presented here focuses on Bayesian unsupervised models as they are well suited to such conditions. This paper presents results from a set of experiments consisting of 38 sessions with labelled victim as well as blind and over-the-shoulder presentation attacks. Three models are compared using this dataset; two single-mode models: a shrunk covariance estimate and a Bayesian Gaussian distribution, as well as a Bayesian non-parametric infinite mixture of Gaussians, modelled as a Dirichlet Process. Equal error rates (EER) for the three models are compared and attention is paid to how these vary across the two single-mode models at differing numbers of enrolment samples.
