description: An electron-phonon cavity consisting of a quantum dot embedded in a free-standing GaAs/AlGaAs membrane is characterized in Coulomb blockade measurements at low temperatures. We find a complete suppression of single electron tunneling around zero bias leading to the formation of an energy gap in the transport spectrum. The observed effect is induced by the excitation of a localized phonon mode confined in the cavity. This phonon blockade of transport is lifted at magnetic fields where higher electronic states with nonzero angular momentum are brought into resonance with the phonon energy.

description: We present a Hubble Space Telescope (HST) survey of extended [OIII] emission for a sample of 60 Seyfert galaxies (22 Seyfert 1's and 38 Seyfert 2's), selected based on their far infrared properties. The observations for 42 of these galaxies were done in a snapshot survey with WFPC2. The remaining 18 were obtained from the HST archive, most of which were observed with the same configuration. These observations cover 68% of the objects in the sample defined by Kinney et al. (2000), and create a valuable dataset for the study of the Narrow Line Region (NLR) properties of Seyfert galaxies. In this paper, we present the details of the observations, reductions, and measurements. We also discuss the extended structure of individual sources, and the relation of this emission to the radio and host galaxy morphology. We also address how representative the subsample of [O III]-imaged galaxies is of the entire sample, and possible selection effects that may affect this comparison of the properties of Seyfert 1 and Seyfert 2 galaxies.

Global 21-cm signal extraction from foreground and instrumental effects III: Utilizing drift-scan time dependence and full Stokes measurements

description: When using valid foreground and signal models, the uncertainties on extracted signals in global 21-cm signal experiments depend principally on the overlap between signal and foreground models. In this paper, we investigate two strategies for decreasing this overlap: (i) utilizing time dependence by fitting multiple drift-scan spectra simultaneously and (ii) measuring all four Stokes parameters instead of only the total power, Stokes I. Although measuring polarization requires different instruments than are used in most existing experiments, all existing experiments can utilize drift-scan measurements merely by averaging their data differently. In order to evaluate the increase in constraining power from using these two techniques, we define a method for connecting Root-Mean-Square (RMS) uncertainties to probabilistic confidence levels. Employing simulations, we find that fitting only one total power spectrum leads to RMS uncertainties at the few K level, while fitting multiple time-binned, drift-scan spectra yields uncertainties at the $\lesssim 10$ mK level. This significant improvement only appears if the spectra are modeled with one set of basis vectors, instead of using multiple sets of basis vectors that independently model each spectrum. Assuming that they are simulated accurately, measuring all four Stokes parameters also leads to lower uncertainties. These two strategies can be employed simultaneously and fitting multiple time bins of all four Stokes parameters yields the best precision measurements of the 21-cm signal, approaching the noise level in the data.

description: An H-mode plasma state free of edge-localized mode (ELM), close to the L-H transition with clear density and temperature pedestal has been observed both at the Joint European Torus (JET) and at the ASDEX Upgrade (AUG) tokamaks usually identified by a low frequency (LFO, 1-2 kHz), m=1, n=0 oscillation of the magnetics and the modulation of pedestal profiles. The regime at JET is referred to as M-mode while at AUG as intermediate phase or I-phase. This contribution aims at a comparative analysis of these phenomena in terms of the density and temperature pedestal properties, the magnetic oscillations and symmetries. Lithium beam emission spectroscopy (Li-BES) and reflectometer measurements at JET and AUG show that the M-mode and the I-phase modulates the plasma edge density. A high frequency oscillation of the magnetics and the density at the pedestal is also associated with both the M-mode and the I-phase, and its power is modulated with the LFO frequency. The power modulation happens simultaneously in every Mirnov coil signal where it can be detected. The bursts of the magnetic signals and the density at the pedestal region are followed by the flattening of the density profile, and by a radially outward propagating density pulse in the scrape-off layer (SOL). The analysis of the helium line ratio spectroscopy (He-BES) signals at AUG revealed that the electron temperature is modulated in phase with the density, thus the I-phase modulates the pressure profile gradient. This analysis gave opportunity to compare Li-BES and He-BES density profiles at different locations suggesting a toroidal and poloidal symmetry of the density modulation. The presented results indicate that the regimes, the AUG I-phase and the JET M-mode, exhibit similar characteristics, which leads to the conclusion that the regimes are likely the same.

title: Kolab: Improvising Nomadic Tangible User Interfaces in the Workplace for Co-Located Collaboration
Creators: name: Mackay, Gordon
Publisher: name: The Open University
Year: 2013

description: Tangible User Interfaces (TUIs) [Ishii 1997] offer an interface style that couples "digital information to everyday physical objects and environments" [Ishii 1997 page 2]. However this physicality may also be a limitation as the tendency to use iconic representations for tangibles can result in inflexible 'concrete and specialised objects' [Shaer 2009 page 107].

The current research investigates whether by reducing the dependence on specific tangible sets through the use of improvised tangibles we may begin to address the issue of tangible flexibility within TUIs. Improvised tangibles may be characterised by being potentially arbitrary and abstract, in that they may bear little or no resemblance to the underlying digital value. Core literature in the field (e. g. [Fitzmaurice 1996] [Ishii 2008] [Hornecker 2006] [Holmquist 1999]) suggests that a system based on improvised tangibles would suffer from impaired usability and so the research focuses on the impact on usability due to a lack of close representational significance [Ullmer 2000] during co-located collaboration.

Using a prototyping methodology a functional, shareable, TUI system was developed based on computer vision techniques using the Microsoft Kinect [Microsoft2011]. This prototype system ('Kolab') was used to explore an interaction design that supports the dynamic binding of improvised tangibles to digital values. A simple co-located collaborative task was developed using 'Kolab' and a user study was conducted to investigate the usability of the system in a collaborative context.

Within the limitations of the simple task the results of the study show that a) users appeared comfortable with improvising artefacts b) the high rate of task completion strongly suggests that a lack of close representational significance does not impair system usability and c) despite some temporary issues with users interfering with other's action an overall indication of equitable participation suggests that collaboration was not impaired by the 'Kolab' prototype.

description: O impacte ambiental causado pelos microplásticos tem sido alvo de investigação pela comunidade científica nos últimos anos. Devido à ubiquidade observada e aos efeitos adversos que provocam nos ecossistemas, torna-se imperativa uma avaliação ecotoxicológica e monitorização dos principais meios recetores destes poluentes emergentes. Neste contexto, este trabalho apresenta ensaios ecotoxicológicos com recurso a kits comerciais como ferramentas promissoras de avaliação ambiental de diferentes matrizes. De acordo com a literatura, verificou-se que estes kits apresentam um elevado grau de sensibilidade que é comparável com o de ensaios padronizados bem estabelecidos, podendo ser uma alternativa viável na identificação de efeitos nocivos causados pelos microplásticos. Por outro lado, por permitirem a obtenção de resultados de forma simples e célere, podem ser úteis em contexto escolar, contribuindo para o aumento da literacia científica.

description: In multiple antenna systems employing time-division duplexing, spatial precoder design at the base station (BS) leverages channel state information acquired through uplink pilot transmission, under the assumption of channel reciprocity. Malicious eavesdroppers can start pilot spoofing attacks to alter such design, so as to improve their eavesdropping performance in downlink. The aim of this paper is to study the effects of pilot spoofing attacks on uplink channel estimation, by assuming that the BS knows the angle of arrivals (AoAs) of the legitimate channels. Specifically, after assessing the performance of the simple least squares estimator (LSE), we consider more sophisticated estimators, such as the maximum likelihood estimator (MLE) and different versions of the minimum mean square error estimator (MMSEE), involving different degrees of a priori information about the pilot spoofing attacks. Theoretical analysis and numerical simulations are used to compare the performance of such estimators. In particular, we analytically demonstrate that the spoofing effects in the high signal-to-noise regime can be completely suppressed, under certain conditions involving the AoAs of the legitimate and spoofing channels. Moreover, we show that even an imperfect knowledge of the AoAs and of the average transmission power of the spoofing signals allows the MLE and MMSEE to achieve significant performance gains over the LSE.

description: We present u'g'r'i'BV photometry and optical spectroscopy of the Type Ib/Ic SN 2005bf covering the first ~100 days following discovery. The u'g'BV light curves displayed a double-peaked morphology, which is among Type Ib/Ic supernovae. The bolometric light curve indicates that SN 2005bf was a remarkably luminous event. Spectroscopically, SN 2005bf underwent a unique transformation from a Type Ic-like event at early times to a typical Type Ib supernova at later phases. The initial maximum in u'g'BV was accompanied by the presence in the spectrum of high velocity absorption lines of Fe II, Ca II, and H I. The photospheric velocity derived from spectra at early epochs was unusually low compared with ordinary Type Ib supernovae. We describe one-dimensional computer simulations which attempt to account for these remarkable properties. The most favored model is that of a very energetic (2 x 10^{51} erg), asymmetric explosion of a massive (8.3 M_sun) Wolf-Rayet WN star that had lost most of its hydrogen envelope. We speculate that an unobserved relativistic jet was launched producing a two-component explosion consisting of 1) a polar explosion containing a small fraction of the total mass and moving at high velocity, and 2) the explosion of the rest of the star. At first, only the polar explosion is observed, producing the initial maximum and the high velocity absorption-line spectrum resembling a Type Ic event. At late times, this fast-moving component becomes optically-thin, revealing the slower-moving explosion of the rest of the star and transforming the observed spectrum to that of a typical Type Ib supernova. If this scenario is correct, then SN 2005bf is the best example to date of a transition object between normal Type Ib/Ic supernovae and gamma ray bursts.

description: We consider a toy model for glassy dynamics of colloidal suspensions: a single Brownian particle diffusing among immobile obstacles. If Gaussian factorization of static density fluctuations is assumed, this model can be solved without factorization approximation for any dynamic correlation function. The solution differs from that obtained from the ideal mode coupling theory (MCT). The latter is equivalent to including only some, positive definite terms in an expression for the memory function. An approximate re-summation of the complete expression suggests that, under the assumption of Gaussian factorization of static fluctuations, mobile particle's motion is always diffusive. In contrast, MCT predicts that the mobile particle becomes localized at a high enough obstacle density. We discuss the implications of these results for models for glassy dynamics.

The fermionic sector of this model is altered by the so called species doubling. We analyze the possibilities to cure this disease and propose an alternative formulation of the fermionic sector free from the above drawbacks. Also we propose a formulation of string bits with exact supersymmetry, which produces however an even number of continuous strings in the limit $J\to\infty$.

description: Most of the experiments on the quantum Hall effect (QHE) were made at approximately the same height above sea level. A future international comparison will determine whether the gravitational field $\mathbf{g}(x)$ influences the QHE. In the realm of (1 + 2)-dimensional phenomenological macroscopic electrodynamics, the Ohm-Hall law is metric independent (`topological'). This suggests that it does not couple to $\mathbf{g}(x)$. We corroborate this result by a microscopic calculation of the Hall conductance in the presence of a post-Newtonian gravitational field.

description: The present paper attempts to estimate the labour employment and resource use efficiency in rubber plantations of Dakshina Kannada district of Karnataka State. Labour employment ,was estimated by converting all the labour employed into mandays of 8 hours giving due weightage for the wage differences and then converting it back into manhours. Resource use efficiencies of labour, fertilizers, plant protection chemicals and capital employed in both small and large farm groups were estimated. The results of the study strengthen the case of rubber cultivation in Dakshina Kannada district with respect to the creation of employment opportunities. This being a new area, the suboptimal use of resources found in the study area may be due to the lack of proper knowhow of rubber cultivation among the farmers. Improved cultivation practices along with proper extension services would make rubber a more profitable enterprise in the locality.

description: Fault-tolerant distributed systems offer high reliability because even if faults in their components occur, they do not exhibit erroneous behavior. Depending on the fault model adopted, hardware and software errors that do not result in a process crashing are usually not tolerated. To tolerate these rather common failures the usual solution is to adopt a stronger fault model, such as the arbitrary or Byzantine fault model. Algorithms created for this fault model, however, are considerably more complex and require more system resources than the ones developed for less strict fault models. One approach to reach a middle ground is the non-malicious arbitrary fault model. This model assumes it is possible to detect and filter faults with a given probability, if these faults are not created with malicious intent, allowing the isolation and mapping of these faults to benign faults. In this paper we describe how we incremented an implementation of active replication in the non-malicious fault model with a basic type of distributed validation, where a deviation from the expected algorithm behavior will make a process crash. We experimentally evaluate this implementation using a fault injection framework showing that it is feasible to extend the concept of non-malicious failures beyond hardware failures.

title: TSC/mTOR Signalling Controls Thymocyte Development and Proliferation/Differentiation of T Lymphocytes and Nerve Cells
Creators: name: Tomasoni, Romana
Publisher: name: The Open University
Year: 2011

description: This thesis is focused on the role of the Tuberous Sclerosis Complex (TSC)/mammalian Target of Rapamycin (mTOR) pathway in the proliferation, survival and differentiation of T cells and PC12 nerve cells. TSC and mTOR play important roles in these cellular processes in different cell models. We wondered which could be the contribution of these pathways in T cells and in particular in thymic development and in another cellular model of differentiation like the PC12 cells. In the first part of the thesis the results of the studies on the differentiation of mature T cells are presented. The involvement of mTORCl and mTORC2 was analysed in these processes by pharmacological inhibition with Rapamycin. The mTOR complexes were found to affect cytokines expression by influencing DNA methylation of their promoters. The role of the TSC pathway in thymic development was then evaluated. TSC1 was genetically inactivated early on during thymic development. It was possible to observe an increase in proliferation and cell death of TSC1 deleted cells. The increased proliferation was due to increased mTORCl signalling, while the increased cell death results from increased FoxO activity, a consequence of defective mTORC2/Akt signalling. The last part of the thesis focuses on the study of the TSC pathway in PC12 cells, a model of neuronal differentiation. The TSC complex plays a critical role in balancing the processes of proliferation and neurosecretory functions in these cells by its ability to affect the β-catenin and REST pathways. The signalling loop that connects these three central players can alternatively control these important processes.

description: The study aimed to calculate the livelihood vulnerability of organic and non-organic rice farmers' households to climate change. The sample was determined by a census comprising 60 organic and 80 non-organic rice farmers who lived in Pematang Sawa Sub-district, Tanggamus Region, Lampung Province, Indonesia. The livelihood vulnerability index (LVI) was measured based on seven main indicators: natural disaster and climate variability, agriculture profile, food security, water security, food/rice consumption, educational attainment, and income. The results showed that organic rice farmers' households were more vulnerable in terms of natural disaster and climate variability, water security, food consumption, education, and income, while non-organic rice farmers' households were more vulnerable in terms of agriculture profile and food security. Using the LVI framework approach of the Intergovernmental Panel on Climate Change (LVI-IPCC), non-organic rice farmers’ households were found to be more vulnerable to climate change than organic rice farmers' households. To better observe the vulnerability of organic and non-organic rice farmers' households to climate change, future studies should be conducted in two distant locations (e.g., different regions or provinces) because different climate components could significantly influence the findings. Rice farmers' households could become less vulnerable by providing them with objective climate information that will encourage them to adopt the necessary climate change adaptation and mitigation strategies. Further support is needed in the form of resources aid programs, such as the provision of irrigation systems or pumping wells, as well as livestock aid to increase the farmers’ income.
Nonlinear evolution of pomeron and odderon in momentum space

description: The small x evolution of the QCD pomeron and the QCD odderon is investigated in the mean field limit of the Color Glass Condensate. The resulting system of coupled nonlinear evolution equations is transformed to the momentum space and analyzed at a very small momentum transfer. The main properties of the C-even and C-odd dipole densities in momentum space are obtained analytically. The critical scaling dimension is found for the odderon and the universal asymptotic behavior of the solutions is determined for small and large gluon momenta. We find that the same saturation scale characterizes both the pomeron and the odderon and both densities depend on the momentum only through the geometric scaling variable. The absorptive effects are found to cause a strong suppression of the odderon exchange amplitude for momenta below saturation scale and only a moderate suppression for larger momenta.

description: The influence of a spherical boundary on the vacuum fluctuations of a massive scalar field is investigated in background of $(D+1)$-dimensional Milne universe, assuming that the field obeys Robin boundary condition on the sphere. The normalized mode functions are derived for the regions inside and outside the sphere and different vacuum states are discussed. For the conformal vacuum, the Hadamard function is decomposed into boundary-free and sphere-induced contributions and an integral representation is obtained for the latter in both the interior and exterior regions. As important local characteristics of the vacuum state the vacuum expectation values (VEVs) of the field squared and of the energy-momentum tensor are investigated. It is shown that the vacuum energy-momentum tensor has an off-diagonal component that corresponds to the energy flux along the radial direction. Depending on the coefficient in Robin boundary condition the sphere-induced contribution to the vacuum energy and the energy flux can be either positive or negative. At late stages of the expansion and for a massive field the decay of the sphere-induced VEVs, as functions of time, is damping oscillatory. The geometry under consideration is conformally related to that for a static spacetime with negative constant curvature space and the sphere-induced contributions in the corresponding VEVs are compared.

Creators: name: Kennard, Harry Robert
Publisher: name: The Open University

description: This MPhil thesis explores two themes associated with the dynamics of inertial particles in turbulent fluids. Firstly, we consider an optimal partial covering of fractal sets in a two-dimensional space using ellipses which become increasingly anisotropic as their size is reduced. If the semi-minor axis is ϵ and the semi-major axis is δ, we set δ = ϵα, where 0 < α < 1 is an exponent characterizing the anisotropy of the ellipses. The optimization involves varying the angle of the principal axis to maximize the measure covered by each ellipse. For point set fractals, in most cases we find that the number of points N which can be covered by an ellipse centred on any given point has expectation value (N) ~ ϵβ, where β is a generalized of the fractal dimension. β(α) is investigated numerically for various sets, showing that it may be different for sets which have the same fractal dimension. Secondly, we examine an analytically solvable limit of a model for the alignment of microscopic rods in a random velocity field with isotropic statistics. The vorticity varies very slowly and the isotropic random flow is equivalent to a pure strain with statistics which are axisymmetric about the direction of the vorticity. We analyse the alignment in a weakly fluctuating uniaxial strain field, as a function of the product of the strain relaxation time τs and the angular velocity ω about the vorticity axis. We find that when τsω >> 1, the rods are predominantly either perpendicular or parallel to the vorticity. We also review the current literature on the dynamics of inertial particles in turbulent flows.

Structure of Disk Dominated Galaxies: II. Color Gradients and Stellar Population Models

description: (Abridged) We investigate optical and near-IR color gradients in a sample of 172 low-inclination galaxies spanning Hubble types S0--Irr. The colors are compared to stellar population synthesis models from which luminosity-weighted average ages and metallicities are determined. We explore the effects of different underlying star formation histories and additional bursts of star formation. Our results are robust in a relative sense under the assumption that our galaxies shared a similar underlying star formation history and that no bursts involving more than ~10% of the galaxy mass have occurred in the past 1-2 Gyr. We find strong correlations in age and metallicity with Hubble-type, rotational velocity, total magnitude, and central surface brightness in the sense that earlier-type, faster rotating, more luminous, and higher surface brightness galaxies are older and more metal-rich, suggesting an early and more rapid star formation history for these galaxies. The increasing trends with rotational velocity and total magnitude level off for V_rot > 120 km/s and M_K < -23 mag respectively. This effect is stronger for metallicity (than age) which could reflect a threshold potential above which all metals are retained and thus metallicity saturates at the yield. Trends in gradients with galaxy parameters are compared with model predictions: these trends do not agree with predictions of semi-analytic models of hierarchical galaxy formation, possibly due to the effect of bar-induced radial flows. The observed trends are in agreement with chemo-spectrophotometric models of spiral galaxy evolution based on CDM-motivated scaling laws but none of the hierarchical merging characteristics, implying a strong dependence of the star formation history of spiral galaxies on the galaxy potential and halo spin parameter.

description: This paper presents the challenges and opportunities of small-scale fisheries management in Misamis Occidental, especially in the coastal municipalities of Aloran, Jimenez, Lopez Jaena, Panaon, Plaridel, Sinacaban, Tudela, and Oroquieta City. A site diagnosis was conducted as part of the participatory diagnosis and adaptive management framework to characterize the governance of small-scale fisheries in the area and to determine the potential for adopting the ecosystem approach to fisheries. Stakeholders identified, in order of priority, the following issues affecting fisheries and coastal resource management in Iligan Bay: depleted fishery resources, lack of alternative livelihood, and limited institutional capabilities. In a united response, the local government units in the area formed the Iligan Bay Alliance of Misamis Occidental, through which they explore opportunities to address issues and to restore and sustain the fisheries in Iligan Bay.

description: Unraveling the 3D physical structure, the temperature and density distribution, of protoplanetary discs is an essential step if we are to confront simulations of embedded planets or dynamical instabilities. In this paper we focus on Submillimeter Array observations of the edge-on source, Gomez's Hamburger, believed to host an over-density hypothesised to be a product of gravitational instability in the disc, GoHam b. We demonstrate that, by leveraging the well characterised rotation of a Keplerian disc to deproject observations of molecular lines in position-position-velocity space into disc-centric coordinates, we are able to map out the emission distribution in the (r, z) plane and (x, y, z) space. We show that 12CO traces an elevated layer of $z\,/\,r \sim 0.3$, while 13CO traces deeper in the disc at $z\,/\,r \lesssim 0.2$. We localize emission associated with GoHam b, finding it at deprojected radius of approximately 500 au and at polar angle of +\- 30 degrees from the disc major axis. At the spatial resolution of $\sim 1.5^{\prime\prime}$, GoHam b is spatially unresolved, with an upper limit to its radius of $<190$~au.

description: The time-dependent scaling of the two-time autocorrelation function of spin systems without disorder undergoing phase-ordering kinetics is considered. Its form is shown to be determined by an extension of dynamical scaling to a local scale-invariance which turns out to be a new version of conformal invariance. The predicted autocorrelator is in agreement with Monte-Carlo data on the autocorrelation function of the 2D kinetic Ising model with Glauber dynamics quenched to a temperature below criticality.

description: In recent years, the Malaysian rice sector has experienced structural changes to improve its competitiveness within a dynamic environment that is influenced by political, technical, economic, and international trade challenges. Using a policy analysis matrix and a rich dataset on rice producing households in four of Malaysia’s granary areas, the competitiveness of rice production in Malaysia is analyzed. The empirical results show that rice production is competitive in three of the four granary areas, the exception being Ketara granary area. To fully understand the importance of the competitive farms, they must be identified and studied by further research using disaggregated data. The finding suggests that government policy should focus on encouraging structural changes capable of enabling the local farms to grow enough to earn sufficient income, generate social profits, and thus improve the sector's competitiveness.
