description: Com mais de 5000 anos de história, o vidro faz parte do quotidiano. O plástico, com uma história muito mais recente, também é um material universal cuja produção ultrapassou outros mais antigos. Em Portugal, há indícios de que a indústria do plástico se desenvolveu a partir da indústria do vidro, com os seus trabalhadores e as suas competências. Atualmente, o plástico é muito visível devido ao seu impacto negativo no meio ambiente, enquanto o vidro, embora tenha sido amplamente utilizado e permitido avanços técnicos significativos, não recebeu tanta atenção do público. O termo Transição Vítrea, que dá o nome à exposição, é um intervalo específico de temperatura no qual, tanto os vidros quanto os plásticos, mudam de um estado sólido para um estado viscoso. A exposição HERIT-AGES: Transições Vítreas - que dá origem a este catálogo - teve como objetivo apresentar os resultados de uma pesquisa exploratória sobre as relações entre as indústrias do vidro e do plástico, além de refletir sobre como a presença desses materiais nos museus pode influenciar as perspetivas das futuras gerações sobre o nosso tempo atual.

description: The spread of modern rice varieties in different water regimes and the factors affecting adoption of modern varieties have been studied using information collected from farmers in the rainfed coastal Orissa. The coverage of modern varieties has been found to be only 37 per cent in mediumland plots and 11 per cent in lowland plots. A multivariable probit model has been used to study the factors affecting adoption of modern varieties. The important factors influencing adoption of a modern variety have been found as hydrology, tenurial status and irrigation. But, the most important factor emerged from the present study is ‘hydrology’. Therefore, a wider spread of modern rice varieties in these areas depends on the development of new varieties that are specifically adapted to these environments. The study has suggested that development of new varieties and irrigation along with adoption of land reform measures will facilitate a faster spread of modern rice varieties in the rainfed coastal Orissa.

MetaMuse : using metaphor to design and play expressive instruments
Creators: name: Gadd, Ashley
Publisher: name: University of British Columbia
Year: 2009

description: This thesis provides a framework for understanding and predicting the expressive nature of devices. We introduce transparency, or the ease with which a device's mapping can be understood, as the main pillar of this framework. Transparency is a predictor for expressivity, the ease with which meaning or emotion can be communicated through the device. We explore the role of metaphor for improving the amount of expression possible with a device, and examine its use as both a design aid and an affordance during use. To validate this theory we built MetaMuse, a controller for a rain-sound synthesiser that employs water metaphors to obviate its use. MetaMuse uses physical props to embody three metaphors: pouring, rainfall, and landscape. These metaphors acted as a guide during MetaMuse's design, and aid users in the prediction of system operation and sound output. We performed a series of experiments comparing MetaMuse to two other interfaces to test our claim that metaphor can be used to improve expressivity. The tests measured controllability with speed and accuracy of sound target acquisition, and expressivity with qualities such as creativity. Accuracy was similar across all interfaces, and speed slightly improved for MetaMuse, but the controllability results lacked significance. Results for expressivity were significant, however: users preferred MetaMuse as more creative than two more traditional controllers (F=6.0, p<0.01). From these results we conclude that metaphor is a worthy design approach to creating expressive devices. This thesis also presents a novel form of synthesis combining techniques from real-time stochastic synthesis and granular synthesis. Finally, it includes a software library for simplifying the use of the Polhemus Fastrak magnetic sensor used in the project.

description: Advanced data augmentation strategies have widely been studied to improve the generalization ability of deep learning models. Regional dropout is one of the popular solutions that guides the model to focus on less discriminative parts by randomly removing image regions, resulting in improved regularization. However, such information removal is undesirable. On the other hand, recent strategies suggest to randomly cut and mix patches and their labels among training images, to enjoy the advantages of regional dropout without having any pointless pixel in the augmented images. We argue that such random selection strategies of the patches may not necessarily represent sufficient information about the corresponding object and thereby mixing the labels according to that uninformative patch enables the model to learn unexpected feature representation. Therefore, we propose SaliencyMix that carefully selects a representative image patch with the help of a saliency map and mixes this indicative patch with the target image, thus leading the model to learn more appropriate feature representation. SaliencyMix achieves the best known top-1 error of 21.26% and 20.09% for ResNet-50 and ResNet-101 architectures on ImageNet classification, respectively, and also improves the model robustness against adversarial perturbations. Furthermore, models that are trained with SaliencyMix help to improve the object detection performance. Source code is available at https://github.com/SaliencyMix/SaliencyMix.

description: Three different film systems have been systematically investigated to understand the effects of strain and substrate constraint on the phase transitions of perovskite films. In SrTiO$_3$ films, the phase transition temperature T$_C$ was determined by monitoring the superlattice peaks associated with rotations of TiO$_6$ octahedra. It is found that T$_C$ depends on both SrTiO$_3$ film thickness and SrRuO$_3$ buffer layer thickness. However, lattice parameter measurements showed no sign of the phase transitions, indicating that the tetragonality of the SrTiO$_3$ unit cells was no longer a good order parameter. This signals a change in the nature of this phase transition, the internal degree of freedom is decoupled from the external degree of freedom. The phase transitions occur even without lattice relaxation through domain formation. In NdNiO$_3$ thin films, it is found that the in-plane lattice parameters were clamped by the substrate, while out-of-plane lattice constant varied to accommodate the volume change across the phase transition. This shows that substrate constraint is an important parameter for epitaxial film systems, and is responsible for the suppression of external structural change in SrTiO$_3$ and NdNiO$_3$ films. However, in SrRuO$_3$ films we observed domain formation at elevated temperature through x-ray reciprocal space mapping. This indicated that internal strain energy within films also played an important role, and may dominate in some film systems. The final strain states within epitaxial films were the result of competition between multiple mechanisms and may not be described by a single parameter.

description: Rural Networks have been implemented as an instrument to enhance EU rural development policies in the funding period 2007-2013. Gaps in European programme documents concerning the networks’ purpose and their evaluation led to a survey of the National Network Units being conducted in 2010. Besides investigating how these gaps are bridged nationally, the survey aimed to provide an overview of the development of the networks, of the initial experiences and challenges faced in running the networks, and to assess their potential impact. Empirical findings show that the networks probably support rural development (policies) and create added value. However, ways of demonstrating this impact in quantitative terms are lacking. Member states tend to stick closely to the specifications provided by the Commission and rarely go beyond them even if they are inadequate – even though this is legally possible. As a result, one purpose originally envisaged for the networks, namely to contribute to improving governance, is neglected. The paper provides proposals for modifying EC Regulations so as to enhance rural networks’ impact and points to the need for further theoretical research corroborating the networks’ value and increasing their effectiveness.

description: A theory of fluctuations in two-band superconductor MgB$_{2}$ is developed. Since the standard Ginzburg-Landau (GL) approach fails in description of its properties, we generalize it basing on the microscopic theory of a two-band superconductor. Calculating the microscopic fluctuation propagator, we build up the nonlocal two-band GL functional and the corresponding time-dependent GL equations. This allows us to calculate the main fluctuation observables such as fluctuation specific heat and conductivity.

Evidence of crossover phenomena in wind speed data

Subjects: subject: Data Analysis, Statistics and Probability (physics.data-an)

description: In this report, a systematic analysis of hourly wind speed data obtained from three potential wind generation sites (in North Dakota) is analyzed. The power spectra of the data exhibited a power-law decay characteristic of $1/f^α$ processes with possible long-range correlations. Conventional analysis using Hurst exponent estimators proved to be inconclusive. Subsequent analysis using detrended fluctuation analysis (DFA) revealed a crossover in the scaling exponent ($α$). At short time scales, a scaling exponent of $α\sim 1.4$ indicated that the data resembled Brownian noise, whereas for larger time scales the data exhibited long range correlations ($α\sim 0.7$). The scaling exponents obtained were similar across the three locations. Our findings suggest the possibility of multiple scaling exponents characteristic of multifractal signals.

description: Polariton condensates propagation is strongly dependent on the particular energy landscape the particles are moving upon, in which the geometry of the pathway laid for their movement plays a crucial role. Bends in the circuits trajectories affect the condensates speed and oblique geometries introduce an additional discretization of the polaritons momenta due to the mixing of short and long axis wavevectors on the propagating eigenvalues. In this work, we study the nature of the propagation of condensates along the arms of a polariton coupler, by a combination of time-resolved micro-tomography measurements and a theoretical model based on a mean field approximation where condensed polaritons are described by an equation for the slow varying amplitude of the polariton field coupled to an equation for the density of incoherent excitons.
Efficient strategies for representing and evaluating the effect of propagation impairments on the performance of wireless communications systems
Creators: name: Liu, Xia
Publisher: name: University of British Columbia
Year: 2009

description: Current methods for assessing the effect of propagation impairments on the link-level performance of wireless communications systems either yield results that apply to certain specific channel conditions or only produce statistical summaries of system performance over a wider range of conditions. Here, we show that a polynomial response surface model can efficiently represent the bit error rate performance of a wireless communications system as a function of standard channel parameters. The result may be used as an complete yet compact equipment performance model useful in higher level system simulation or as an aid to visualization of system performance. When two channel parameters are considered, a fifth order polynomial is sufficient to model the bit error rate performance over a reasonable range of channel conditions. This implies that a complete description of system performance can be captured using just twenty-one parameters. Furthermore, compared to regular sampling, adaptive sampling of the response surface can significantly reduce the time and effort required to generate a response surface model from physical layer simulations. While the results presented here were generated by simulation, our response surface model and adaptive sampling method could also be applied to experimental methods that assess the link-level performance of wireless communications systems using RF channel emulators.

description: In this paper, a systematic analysis of hourly wind speed data obtained from four potential wind generation sites in North Dakota is conducted. The power spectra of the data exhibited a power law decay characteristic of $1/f^α$ processes with possible long range correlations. The temporal scaling properties of the records were studied using multifractal detrended fluctuation analysis {\em MFDFA}. It is seen that the records at all four locations exhibit similar scaling behavior which is also reflected in the multifractal spectrum determined under the assumption of a binomial multiplicative cascade model.

description: We consider the natural problem of counting isotopy classes of essential surfaces in 3-manifolds, focusing on closed essential surfaces in a broad class of hyperbolic 3-manifolds. Our main result is that the count of (possibly disconnected) essential surfaces in terms of their Euler characteristic always has a short generating function and hence has quasi-polynomial behavior. This gives remarkably concise formulae for the number of such surfaces, as well as detailed asymptotics. We give algorithms that allow us to compute these generating functions and the underlying surfaces, and apply these to almost 60,000 manifolds, providing a wealth of data about them. We use this data to explore the delicate question of counting only connected essential surfaces and propose some conjectures. Our methods involve normal and almost normal surfaces, especially the work of Tollefson and Oertel, combined with techniques pioneered by Ehrhart for counting lattice points in polyhedra with rational vertices. We also introduce a new way of testing if a normal surface in an ideal triangulation is essential that avoids cutting the manifold open along the surface; rather, we use almost normal surfaces in the original triangulation.

However, the application of bare neodymium thin film is limited due to the lack of information about its electrical and magnetic properties. We report synergistic study of Nd thin film using experimental and theoretical techniques of polarized neutron reflectometry, magnetoresistance measurement and density functional theory. Unlike bulk Nd, thin film specimen is a very poor electrical conductor. Also, as grown thin film on silicon substrate does not exhibit any magnetism in zero field. However, moderate inplane field application of $H$ = 1.2 T tends to induce weak magnetism in the system at low temperature of $T$ $

description: Commutative four dimensional supersymmetric Yang-Mills (SYM) is known to be renormalizable for ${\mathcal N} = 1, 2$, and finite for ${\mathcal N} = 4$. However, in the noncommutative version of the model the UV/IR mechanism gives rise to infrared divergences which may spoil the perturbative expansion. In this work we pursue the study of the consistency of the ${\cal N} = 1, 2, 4$ noncommutative supersymmetric Yang-Mills theory with gauge group U(N) (NCSYM). We employ the covariant superfield framework to compute the one-loop corrections to the two- and three-point functions of the gauge superfield $V$. It is found that the cancellation of the harmful UV/IR infrared divergences only takes place in the fundamental representation of the gauge group. We argue that this is in agreement with the low energy limit of the open superstring in the presence of an external magnetic field. As expected, the planar sector of the two-point function of the $V$ superfield exhibits UV divergences. They are found to cancel, in the Feynman gauge, for the maximally extended ${\cal N} = 4$ supersymmetric theory. This gives support to the belief that the ${\cal N} = 4$ NCSYM theory is UV finite.

description: Metal/Insulator/Metal nanocavities (MIMs) are highly versatile systems for nanometric light confinement and waveguiding, and their optical properties are mostly interpreted in terms of surface plasmon polaritons. Although classic electromagnetic theory accurately describes their behavior, it often lacks physical insight, letting some fundamental aspects of light interaction with these structures unexplored. In this work, we elaborate a quantum mechanical description of the MIM cavity as a double barrier quantum well. We identify the square of the imaginary part of the refractive index of the metal as the optical potential, and find that MIM cavity resonances are suppressed if the ratio n/\k{appa} exceeds a certain limit, which shows that low n and high \k{appa} are desired for strong and sharp cavity resonances. Interestingly, the spectral regions of cavity mode suppression correspond to the interband transitions of the metals, where the optical processes are intrinsically non-Hermitian. The quantum treatment allows to describe the tunnel effect for photons, and reveals that the MIM cavity resonances can be excited by resonant tunneling via illumination through the metal, without the need of momentum matching techniques such as prisms or grating couplers. By combining this analysis with spectroscopic ellipsometry on experimental MIM structures, and by developing a simple harmonic oscillator model of the MIM for the calculation of its effective permittivity, we show that the cavity eigenmodes coincide with low-loss zeros of the effective permittivity.

description: The effect of impurities on the grain boundary melting of ice is investigated through an extension of Derjaguin-Landau-Verwey-Overbeek theory, in which we include retarded potential effects in a calculation of the full frequency dependent van der Waals and Coulombic interactions within a grain boundary. At high dopant concentrations the classical solutal effect dominates the melting behavior. However, depending on the amount of impurity and the surface charge density, as temperature decreases, the attractive tail of the dispersion force interaction begins to compete effectively with the repulsive screened Coulomb interaction. This leads to a film-thickness/temperature curve that changes depending on the relative strengths of these interactions and exhibits a decrease in the film thickness with increasing impurity level. More striking is the fact that at very large film thicknesses, the repulsive Coulomb interaction can be effectively screened leading to an abrupt reduction to zero film thickness.

Threshold estimation using wavelets and curvelets on ground penetrating radar data for noise and clutter suppresion
Creators: name: Harrison, Dustin
Publisher: name: University of British Columbia
Year: 2009

description: This thesis provides an evaluation of the Redundant Discrete Wavelet Transform with application to the removal of additive white or colored Gaussian noise on a synthetic GPR signal. Special attention is given to the parameter that controls the number of decomposition levels. Evaluation is performed using a level-dependent threshold to estimate and remove noise. Results are presented using noisy synthetic Ground Penetrating Radar pulses to compare Wiener filtering and thresholding the Redundant and Non-redundant Discrete Wavelet transform. Additional results are presented on the effects of choosing a number of decomposition levels using signal-to-noise ratio measurements, which suggest the importance of choosing this parameter. Recommendations are made and supported which determine the order of thresholding before or after the practice of trace averaging. Using GPR images, an application of a novel 2D threshold model in the newly discovered curvelet domain is compared to average trace subtraction. Promising results are presented on both synthetic and actual landmine data, which shows thresholding as a viable method of clutter suppression.

description: We study a model for dynamical localization of topology using ideas from non-commutative geometry and topology in quantum mechanics. We consider a collection $X$ of $N$ one-dimensional manifolds and the corresponding set of boundary conditions (self-adjoint extensions) of the Dirac operator $D$. The set of boundary conditions encodes the topology and is parameterized by unitary matrices $g_N$. A particular geometry is described by a spectral triple $x(g_N)=(A_X,{\cal H}_X, D(g_N))$. We define a partition function for the sum over all $g_N$. In this model topology fluctuates but the dimension is kept fixed. We use the spectral principle to obtain an action for the set of boundary conditions. Together with invariance principles the procedure fixes the partition function for fluctuating topologies. In the simplest case the model has one free-parameter $β$ and it is equivalent to a one plaquette gauge theory. We argue that topology becomes localized at $β=\infty$ for any value of $N$. Moreover, the system undergoes a third-order phase transition at $β=1$ for large $N$. We give a topological interpretation of the phase transition by looking how it affects the topology.

description: The recent ALMA DSHARP survey provided illuminating results on the diversity of substructures in planet forming disks. These substructures trace pebble-sized grains accumulated at local pressure maxima, possibly due to planet-disk interactions or other planet formation processes. DSHARP sources are heavily biased to large and massive disks that only represent the high (dust flux) tail end of the disk population. Thus it is unclear whether similar substructures and corresponding physical processes also occur in the majority of disks which are fainter and more compact. Here we explore the presence and characteristics of features in a compact disk around GQ Lup A, the effective radius of which is 1.5 to 10 times smaller than those of DSHARP disks. We present our analysis of ALMA 1.3mm continuum observations of the GQ Lup system. By fitting visibility profiles of the continuum emission, we find substructures including a gap at ~ 10 au. The compact disk around GQ Lup exhibits similar substructures to those in the DSHARP sample, suggesting that mechanisms of trapping pebble-sized grains are at work in small disks as well. Characteristics of the feature at ~ 10 au, if due to a hidden planet, are evidence of planet formation at Saturnian distances. Our results hint at a rich world of substructures to be identified within the common population of compact disks, and subsequently a population of solar system analogs within these disks. Such study is critical to understanding the formation mechanisms and planet populations in the majority of protoplanetary disks.

description: We consider a new class of 5-dimensional dilatonic actions which are invariant under T-duality transformations along three compact coordinates, provided that an appropriate potential is chosen. We show that the invariance remains when we add a boundary term corresponding to a moving 3-brane, and we study the effects of the T-duality symmetry on the brane cosmological equations. We find that T-duality transformations in the bulk induce scale factor duality on the brane, together with a change of sign of the pressure of the brane cosmological matter. However, in a remarkable analogy with the Pre-Big Bang scenario, the cosmological equations are unchanged. Finally, we propose a model where the dual phases are connected through a scattering of the brane induced by an effective potential. We show how this model can realise a smooth, non-singular transition between a pre-Big Bang superinflationary Universe and a post-Big Bang accelerating Universe.

Graph-Theoretical Techniques in Nuclear Decay Pathway Optimization
Creators: name: Francesco D'Agostino
Publisher: name: Zenodo
Year: 2025

description: This paper proposes a system for nuclear decay dynamics and synthesis pathway optimization is developed via spectral analysis and Galois symmetry constraints. Key results include spectral decompositions that respect algebraic symmetries, exponential convergence governed by the spectral gap, and an algebraic characterization of optimal synthesis costs. These findings yield precise, scale‐invariant predictions for nuclear stability and synthesis feasibility.
Classical rotational inertia of solid helium 4

description: The observation of reduced rotational inertia in a cell containing solid helium 4 has been interpreted as evidence for superfluidity of the solid. An alternative explanation is slippage of the solid at the container wall due to grain boundary premelting between the solid and dense adsorbed layers at the container wall. We calculate the range of film thickness and the viscous drag, and find that the slippage can account for the observations.

description: In view of the complexity and non-linearity of energy consumption system and the status quo of the development of energy in Qinghai province, the relations between energy consumption and industrial structure is analyzed by using the quantitative analysis of grey relation degree by using the grey system theory. The relevancy degree among the primary industry, the secondary industry and the tertiary industry and living energy consumption are obtained, and then the trend of energy consumption in the following several years can be predicted. The results show that the secondary industry has the largest relevancy degree to the total energy consumption. In the end, according to the results of the research, several suggestions on how to saving energy are put forward. Firstly, the government should improve the high-tech industry and restrict the development of high-consumption and high-pollution industries. Secondly, the government should promote the low-carbon way of life; promote energy saving and control the energy consumption of the department of life. Thirdly, clean production should be actively promoted in the tertiary industry and the circular economy should be vigorously expanded.

description: 4.3. HPLC isolation of GHQ (9) from G. thurberi
 Isolation of GHQ (9) was initially achieved from a G. thurberi extract [10 g tissue in CH 3 CN (10 mL)] on the Agilent HPLC instrument using a Scientific Glass Engineering ProteCol-GP-C18-125 (4.6 × 250 mm) column at 23–24 ° C and an isocratic mobile phase of 3:1 CH 3 CN:H 2 O with 0.1% HCO 2 H. The flow rate was 1.25 mL/ min and the run time was 20 min. The eluent was monitored at 272 ± 10 nm (referenced to 550 ± 50 nm) and spectra of detected peaks were stored over 210–600 nm. Multiple injections of 50 µL were carried out and the peak of interest was manually collected from the eluent from the DAD. The collected fractions were extracted three times with Et 2 O after the addition of an equal volume of H 2 O. Back washing with H 2 O (2×), drying over Na 2 SO 4 and final evaporation provided the compound of interest (>95% pure).

description: Marcasite class of compounds provide facile platform to explore novel phenomena of fundamental and technological importance, such as unconventional superconductivity or high performance electrocatalyst. We report the synthesis and experimental investigation of a new marcasite CoSeAs in this letter. Experimental investigation of the new material using neutron scattering measurements reveal weak magnetic correlation of cobalt ions below $T$ = 36.2 K. The modest isotropic exchange interaction between cobalt moments, inferred from random phase approximation analysis, hints of magnetically unstable environment. It is a desirable characteristic to induce unconventional superconductivity via chemical pressure application

description: For continuous γ, g:[0,1]\to(0,\infty), consider the degenerate stochastic differential equation dX_t=[1-|X_t|^2]^{1/2}γ(|X_t|) dB_t-g(|X_t|)X_t dt in the closed unit ball of R^n. We introduce a new idea to show pathwise uniqueness holds when γand g are Lipschitz and \frac{g(1)}{γ^2(1)}>\sqrt2-1. When specialized to a case studied by Swart [Stochastic Process. Appl. 98 (2002) 131-149] with γ=\sqrt2 and g\equiv c, this gives an improvement of his result. Our method applies to more general contexts as well. Let D be a bounded open set with C^3 boundary and suppose h:\barD\to R Lipschitz on \barD, as well as C^2 on a neighborhood of \partial D with Lipschitz second partials there. Also assume h>0 on D, h=0 on \partial D and |\nabla h|>0 on \partial D. An example of such a function is h(x)=d(x,\partial D). We give conditions which ensure pathwise uniqueness holds for dX_t=h(X_t)^{1/2}σ(X_t) dB_t+b(X_t) dt in \barD.
