description: In this paper, we investigate the feature encoding process in a prototypical energy-based generative model, the Restricted Boltzmann Machine (RBM). We start with an analytical investigation using simplified architectures and data structures, and end with numerical analysis of real trainings on real datasets. Our study tracks the evolution of the model's weight matrix through its singular value decomposition, revealing a series of phase transitions associated to a progressive learning of the principal modes of the empirical probability distribution. The model first learns the center of mass of the modes and then progressively resolve all modes through a cascade of phase transitions. We first describe this process analytically in a controlled setup that allows us to study analytically the training dynamics. We then validate our theoretical results by training the Bernoulli-Bernoulli RBM on real data sets. By using data sets of increasing dimension, we show that learning indeed leads to sharp phase transitions in the high-dimensional limit. Moreover, we propose and test a mean-field finite-size scaling hypothesis. This shows that the first phase transition is in the same universality class of the one we studied analytically, and which is reminiscent of the mean-field paramagnetic-to-ferromagnetic phase transition.

description: We demonstrate that significant effects in the "superluminal propagation"of light-pulses cannot be observed without involving systems whose gain explodes outside the pulse spectrum. We explicitly determine the minimum norm of the gain to attain given superluminal effects and the transfer function of the corresponding optimal system. The gain-norms which would be required with the most efficient systems considered up to now (dispersive media, photonic barriers) to attain the same effects are shown to exceed the minimum by several orders of magnitude. We finally estimate the largest superluminal advances which could be attained in a realistic experiment.
Wittgenstein’s Picture Theory of Pictures

description: I rely on Frascolla's interpretation of the Tractatus ontology to develop an account of depiction in which a picture is conceived of as a visual structure constituted by pixels that are conceived of, in their turn, as elementary propositions. Then I argue that such an account is complementary to the considerations about «noticing aspects» in the Philosophical Investigations, to the extent that the visual structure constituted by pixels provides a design allowing the picture’s viewer to notice aspects. Finally I argue that a joint reading of the considerations about pictures in the Tractatus and in the Philosophical Investigations allows us to address some important issues in the contemporary philosophical debate about depiction.

description: A framework for understanding the determinants in the variation in the pricing of skills across countries and the model underlying the Mincer specification of wages that is used widely to estimate the relationship between schooling and wages are described. A method for identifying skill prices and for testing the Mincer model, using wages and the human capital attributes of workers located around the world, is discussed. A global wage equation that nests the Mincer specification is estimated that provides skill price estimates for 140 countries. The estimates reject the Mincer model. The skill price estimates indicate that variation in skill prices dominates the cross-country variation in schooling levels or rates of return to schooling in accounting for the global inequality in the earnings of workers worldwide. Variation in skill prices and GDP across countries has opposite and significant effects on the number and quality of migrants to the United States.

description: The quadratic low-temperature dependence of resistance in ordinary metals is determined by the momentum relaxation due to electron-electron scattering in the presence Umklapp processes and scattering on impurities. In metals without inversion center spin-orbit interaction of electrons with crystal lattice lifts spin degeneracy of electron states and splits each band on two bands. The temperature dependence of electron-electron collisions scattering rate is found using the matrix kinetic equation including the electron-impurity and electron-electron intra and inter band scattering. It is shown that in clean enough case when the energy of band splitting exceeds the electron-impurity scattering rate but at the same time it is much smaller than the Fermi energy the square low-temperature dependence of resistivity is still valid.

We show that TDGL have $t$-dependent and spatially uniform solutions that describe the order parameter with an oscillating part of the double frequency coexisting with an ac electric field. We evaluate the Ohmic losses (related neither to the flux flow nor to the phase slips) and show that the resistivity reduction on cooling through the critical temperature $T_c$ should behave as $(T_c-T)^2/ω^2$. If the channel is cut out of an anisotropic material in a direction other than the principal axes, the transverse phase difference and the Josephson voltage between the channel sides are generated.

description: This paper presents a posteriori error estimates for conforming numerical approximations of eigenvalue clusters of second-order self-adjoint elliptic linear operators with compact resolvent. Given a cluster of eigenvalues, we estimate the error in the sum of the eigenvalues, as well as the error in the eigenvectors represented through the density matrix, i.e., the orthogonal projector on the associated eigenspace. This allows us to deal with degenerate (multiple) eigenvalues within the framework. All the bounds are valid under the only assumption that the cluster is separated from the surrounding smaller and larger eigenvalues; we show how this assumption can be numerically checked. Our bounds are guaranteed and converge with the same speed as the exact errors. They can be turned into fully computable bounds as soon as an estimate on the dual norm of the residual is available, which is presented in two particular cases: the Laplace eigenvalue problem discretized with conforming finite elements, and a Schr{ö}dinger operator with periodic boundary conditions of the form $--$Δ$ + V$ discretized with planewaves. For these two cases, numerical illustrations are provided on a set of test problems.
On Satzklang: on the Sense and on the Nonsense
Creators: name: Distaso, Leonardo
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2013

description: The Wittgenstein’s notion of plain and patent nonsense is fertile because it shows the discovery of the ambiguity of the sense, in particular of the nonsense of contingency at the end of complete clarification. All the reflection of Wittgenstein’s philosophy is a question on the possibility of crossing, from the inside, language as it is to move from the hidden nonsense of the contingency of the language and of the reality to the patent nonsense of the philosophy. But since the clarity of the patent nonsense shows the paradoxical situation of our condition, the limits of the language, the patent nonsense is also the real discovery of the Philosophy that makes me capable of stopping doing philosophy when I want to. This is the aesthetical dimension of the sense, in which the patent nonsense makes a transition to the hidden and enigmatic nonsense. It is on the level of this hidden nonsense that we can find the notion of Satzklang: sound of proposition. When we grasp in a flash, when we hear and we pronounce a word or a proposition, we catch the sound of the word that has directly to do with its meaning or its application, and it brings us back to that preliminary dimension in which we belong to a language that guarantees the possibility of the meaning of what we say, a possibility that reveals itself only in a dimension of non-sense: the echo of the original sounds of the language as it stands as enigmatically senseless because it poses itself as a condition for any language, in a primitive and primeval dimension of language. The paradigmatic aesthetical experiences called understanding a musical theme and understanding a poem, the question about the meaning of the sounds and the meaning of a theme in music show are described from the transiction from patent nonsense to something which is hidden nonsense. The analysis of the sound of proposition shows the sense of nonsense moving toward the inaccessible original place of the language: the place of having the taking-place of language itself.

They obtained sharp regularity results for minimizers of such functionals. In this paper we treat the case that the exponents are functions of $x$ and partly generalize their regularity results.

The data disfavor these exotic possibilities even at a sub-dominant level, and stringent 90% C.L. limits are placed on the Lorentz invariance violation parameter |Delta v| < 6 * 10^(-24) at sin2theta_v = 0 and |Delta v| < 2.5--5 * 10^(-26) at sin2theta_v = +/-1. These limits can also be re-interpreted as upper bounds on the parameters describing violation of the Equivalence Principle.

description: Following a series of bilateral and multilateral agreements, the past two decades have seen increased trade and investment liberalization between Canada and the United States in the agri-food sector. Changes in trade policy are one of several paths by which farm structure can change. This increased liberalization, together with the largest drop in Canadian farm numbers recorded by the Census of Agriculture in thirty years, has provided the impetus to review some aspects of farm structure. In particular, this article presents the latest Canadian and U.S. data on the number of farms by sales class, the concentration of sales and other production-related variables, and the distribution of income and receipts. We explore whether significant changes in the latter two elements of farm structure have occurred during this period of trade and investment liberalization.

description: Increasing availability and quality of actual, as opposed to scheduled, open transport data offers new possibilities for capturing the spatiotemporal dynamics of the railway and other networks of social infrastructure. One way to describe such complex phenomena is in terms of stochastic processes. At its core, a stochastic model is domain-agnostic and algorithms discussed here have been successfully used in other applications, including Google's PageRank citation ranking. Our key assumption is that train routes constitute meaningful sequences analogous to sentences of literary text. A corpus of routes is thus susceptible to the same analytic tool-set as a corpus of sentences. With our experiment in Switzerland, we introduce a method for building Markov Chains from aggregated daily streams of railway traffic data. The stationary distributions under normal and perturbed conditions are used to define systemic risk measures with non-evident,valuable information about railway infrastructure.
Numerical solution of semidefinite constrained least squares problems
Creators: name: Krislock, Nathan Gavin Beauregard
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, we are concerned with computing the least squares solution of the linear matrix equation AX = B subject to the constraint that the matrix X is positive semidefinite. For symmetric X, this is the previously studied semidefinite least squares (SDLS) problem; for nonsymmetric X, we introduce the nonsymmetric semidefinite least squares (NS-SDLS) problem. An application of this second problem is the estimation of the compliance matrix at some location on a deformable object. This is an important step in the process of making interactive computer models of de-formable objects, a technique which is used in the area of medical simulation. We also introduce a third semidefinite constrained least squares problem called the linear matrix inequality least squares (LMI-LS) problem, which is a generalization of the first two problems. Sufficient conditions for the existence and uniquenss of solutions for each of these three problems is provided. These solutions are characterized as solutions of nonlinear systems of equations known as the Karush-Kuhn-Tucker (KKT) equations. It is shown that the KKT equations for each of these problems can be stated as a semidefinite linear complementarity problem (SDLCP). Interior-point methods are proposed for the numerical solution of each of these three problems. Computational experiments are conducted which indicate that predictor-corrector interior-point methods solve these semidefinite constrained least squares problems efficiently. A noticable improvement is made over the current computational methods used for solving the SDLS problem.
Economic Features of Canadian Organic Food at the Mass-market Retail Level

description: Over the past decade, Canada’s organic food industry has focused on the production of organic grains, oilseeds, fruits and vegetables and a limited amount of organic dairy products. Canadian organic grains and oilseeds are mostly destined for export, whereas Canadian organic fruits and vegetables and dairy products are mostly consumed domestically. With the exception of dairy products and a few other products such as breakfast cereal and fruit juice, Canadian companies have been mostly absent from the rapidly growing markets for processed organic foods. The extent to which these markets are currently being penetrated by Canadian organic food manufacturers and the size of the price premiums earned by these companies are worthy of investigation. Very little information exists about market structure and price premiums for processed organic foods sold in North American mass-market retail outlets. Market studies of Canada’s organic food market typically use a previously determined 30 percent price premium estimate for organic foods as a whole, and most studies are silent about specific characteristics of organic food manufacturers. In order for Canadian firms to increase their presence in the market for processed organic foods, more detailed information about market structure and the distribution of price premiums is needed.
Spectral functions and dynamic critical behavior of relativistic $Z_2$ theories

description: We investigate the dynamic critical behaviour of a relativistic scalar field theory with $Z_2$ symmetry by calculating spectral functions of the order parameter at zero and non-vanishing momenta from first-principles classical-statistical lattice simulations in real-time. We find that at temperatures above the critical point $(T > T_c)$, the spectral functions are well described by relativistic quasi-particle peaks. Close to the transition temperature $(T \sim T_c)$, we observe strong infrared contributions building up. In the ordered phase at low temperatures $(T < T_c)$, in addition to the quasi-particle peak, we observe a soft mode with a dispersion relation indicative of collective excitations. Investigating the spectral functions close to $T_c$, we demonstrate that the behavior in the vicinity of the critical point is controlled by dynamic scaling functions and the dynamic critical exponent $z$, which we determine from our simulations. By considering the equations of motion for a closed system and a system coupled to a heat bath, we extract the dynamic critical behavior for two different dynamic universality classes (Models A & C) in two and three spatial dimensions.

description: Groundwater and surface water in the South Platte River basin of northeastern Colorado are hydraulically linked. Consequently, use of groundwater in the basin reduces surface water flows in the South Platte River. To avoid open-access problems in this situation, both surface water and groundwater in the basin are jointly administered under the prior appropriation doctrine. This gives preference to the earliest developed water rights relative to later rights when water supplies are insufficient to meet all demands. Groundwater development typically occurred after surface water development, so rights related to groundwater are generally sufficiently junior as to be exercised only in the wettest years. Historically, the state engineer has been empowered to allow groundwater pumping out of priority as long as the associated surface water depletion was replaced with a commensurate amount of water from an alternative source. During a severe drought in the summer of 2002, however, groundwater users pumped water in the expectation of alternative sources that never materialized. The Colorado Supreme Court later found that groundwater users were injuring senior water users by using water out of priority. Primary policy questions arise as to the impact this out-of-priority pumping had on farm failures during the drought and the role water allocation institutions in the region played in allowing out-of-priority pumping.
Obtaining alpha from B-->rho+- pi-+

description: We discuss how to extract the weak phase alpha from present data on B--> rho+- pi-+ decays. Introducing alpha_{eff} and constraining the difference from alpha using flavor SU(3), one arrives at alpha=(95+- 16) degrees, if a testable assumption of a small relative strong phase between the two relevant tree amplitudes is employed to distinguish between discrete ambiguities. On the long run we advocate the combined fit to B--> rho+- pi-+ and SU(3) related modes. The effect of SU(3) breaking in this approach is expected to be small, because of relatively small penguin pollution.

description: The discharge of elongated particles from a silo with rotating bottom is investigated numerically. The introduction of a slight transverse shear reduces the flow rate $Q$ by up to 70% compared to stationary bottom, but the flow rate shows a modest increase by further increasing the external shear. Focusing on the dependency of flow rate $Q$ on orifice diameter $D$, the spheres and rods show two distinct trends. For rods, in the small aperture limit $Q$ seems to follow an exponential trend, deviating from the classical power-law dependence. These macroscopic observations are in good agreement with our earlier experimental findings [Phys. Rev. E $\textbf{103}$, 062905 (2021)]. With the help of the coarse-graining methodology we obtain the spatial distribution of the macroscopic density, velocity, kinetic pressure, and orientation fields. This allows us detecting a transition from funnel to mass flow pattern, caused by the external shear. Additionally, averaging these fields in the region of the orifice reveals that the strong initial decrease in $Q$ is mostly attributed to changes in the flow velocity, while the weakly increasing trend at higher rotation rates is related to increasing packing fraction. Similar analysis of the grain orientation at the orifice suggests a correlation of the flow rate magnitude with the vertical orientation and the packing fraction at the orifice with the order of the grains. Lastly, the vertical profile of mean acceleration at the center of the silo denotes that the region where the acceleration is not negligible shrinks significantly due to the strong perturbation induced by the moving wall.

description: We observed electromagnetically induced transparency (EIT) and dark fluorescence in a cascade three-level diatomic Lithium system using Optical-Optical Double Resonance (OODR) spectroscopy. When a strong coupling laser couples the intermediate state $A^{1}Σ^{+}_{u}(v=13, J=14)$ to the upper state $G^{1}Π_{g}(v=11, J=14)$ of $^7Li_2$, the fluorescence from both $A^{1}Σ^{+}_{u}$ and $G^{1}Π_{g}$ states was drastically reduced as the weak probe laser was tuned through the resonance transition between the ground state $X^{1}Σ^{+}_{g}(v=4, J=15)$ and the excited state $A^{1}Σ^{+}_{u}(v=13, J=14)$. The strong coupling laser makes an optically thick medium transparent for the probe transition. In addition, The fact that fluorescence from the upper state $G^{1}Π_{g}(v=11, J=14)$ was also dark when both lasers were tuned at resonance implies that the molecules were trapped in the ground state. We used density matrix methods to simulate the response of an open molecular three-level system to the action of a strong coupling field and a weak probe field. The analytical solutions were obtained under the steady-state condition. We have incorporated the magnetic sublevel (M) degeneracy of the rotational levels in the lineshape analysis and report $|M|$ dependent lineshape splitting. The theoretical calculations are in excellent agreement with the observed fluorescence spectra. We show that the coherence is remarkably preserved even when the coupling field was detuned far from the resonance.

description: As philosophers we look-through a phenomenon and we see as it appears. The philosopher feels the sensation of dissatisfaction and lives in revolt against an instinctive dissatisfaction with the language. We see as the words are played, because they are source of confusion. He searches the liberating word, which liberates us from dissatisfaction or mental cramps: it subverts an idea, renews a thought, creates new knowledge and opens to the difference. The choice of words, based on the listening to the words, is an aesthetic analyse, in the sense that it is a pursuit of pleasure and an avoidance of pain.

description: Agricultural research has been a very important factor in enhancing the productivity and competitiveness of the Canadian agri-food sector. Science and innovation have been identified as together forming one of the five pillars in the Canadian Agri-food Policy Framework (APF). A major focus of the science and innovation section of the APF is to plan to realign public and private research efforts into a more comprehensive strategic approach for research and innovation in Canada. Despite the importance of research and the need for a strategic approach, however, assessment of critical strategic research policy issues for the Canadian agri-food sector has been limited.

description: We investigate the physical nature of blue cores in early-type galaxies through the first multi-wavelength analysis of a serendipitously discovered field blue-nucleated spheroid in the background of the deep ACS/WFC griz multicolor observations of the cluster Abell 1689. The resolved g-r, r-i and i-z color maps reveal a prominent blue core identifying this galaxy as a ``typical'' case study, exhibiting variations of 0.5-1.0 mag in color between the center and the outer regions, opposite to the expectations of reddened metallicity induced gradients in passively evolved ellipticals. From a Magellan-Clay spectrum we secure the galaxy redshift at $z=0.624$. We find a strong X-ray source coincident with the spheroid galaxy. Spectral features and a high X-ray luminosity indicate the presence of an AGN in the galaxy. However, a comparison of the X-ray luminosity to a sample derived from the Chandra Deep Field South displays Lx to be comparable to Type I/QSO galaxies while the optical flux is consistent with a normal star-forming galaxy. We conclude that the galaxy's non-thermal component dominates at high-energy wavelengths while we associate the spheroid blue light with the stellar spectrum of normal star-forming galaxies. We argue about a probable association between the presence of blue cores in spheroids and AGN activity.

description: Complementary metal oxide semiconductor (CMOS) logic circuits at the ultimate scaling limit place the utmost demands on the properties of all materials involved. The requirements for semiconductors are well explored and could possibly be satisfied by a number of layered two-dimensional (2D) materials, like for example transition-metal dichalcogenides or black phosphorus. The requirements for the gate insulator are arguably even more challenging and difficult to meet. In particular the combination of insulator to semiconductor which forms the central element of the metal oxide semiconductor field effect transistor (MOSFET) has to be of superior quality in order to build competitive devices. At the moment, hexagonal boron nitride (hBN) is the most common two-dimensional insulator and widely considered to be the most promising gate insulator in nanoscaled 2D material-based transistors. Here, we critically assess the material parameters of hBN and conclude that while its properties render hBN an ideal candidate for many applications in 2D nanoelectronics, hBN is most likely not suitable as a gate insulator for ultrascaled CMOS devices.

A relativistic toy model for back-reaction

description: We consider a quantized massless and minimally coupled scalar field on a circular closed string with a time-dependent radius $R(t)$, whose undisturbed dynamics is governed by the Nambu-Goto action. Within the semi-classical treatment, the back-reaction of the quantum field onto the string dynamics is taken into account in terms of the renormalized expectation value of the energy-momentum tensor including the trace anomaly. The results indicate that the back-reaction could prevent the collapse of the circle $R\downarrow0$ -- however, the semi-classical picture fails to describe the string dynamics at the turning point (i.e., possible bounce) at finite values of $R$ and $\dot R$. The fate of the closed string after that point (e.g., oscillation or eternal acceleration) cannot be determined within the semi-classical picture and thus probably requires the full quantum treatment.

description: We study the Dirac and the klein-Gordon oscillators in a noncommutative space. It is shown that the Klein-Gordon oscillator in a noncommutative space has a similar behaviour to the dynamics of a particle in a commutative space and in a constant magnetic field. The Dirac oscillator in a noncommutative space has a similar equation to the equation of motion for a relativistic fermion in a commutative space and in a magnetic field, however a new exotic term appears, which implies that a charged fermion in a noncommutative space has an electric dipole moment.

description: The grain handling sector in Canada and the United States is vital to agriculture and trade. In a typical year on the Canadian prairies, about 140,000 producers deliver some 20 to 30 mmt of grain for export to primary elevators. In the United States, about 2.1 million producers deliver about 300 mmt of grain to primary elevators. Canadian grain is moved to export position using more than 400,000 hopper cars and marine containers, where about 1,200 ships per year are loaded. In the United States, about 1.08 million rail carloads of grain are originated per year, and about 23 mmt of grain are shipped on barges per year. These U.S. figures are in addition to trucks, which, more so than in Canada, are also used to deliver grain to primary processors and to terminal and export markets. The volume of grain trade gives rise to concern about risks of terrorism in the sector.(1) From a security perspective, the grain, pulse and oilseed supply chain is noteworthy because much of it is characterized by relatively long-term, insecure, bulky storage (particularly on farms) along with numerous modal and inter-modal product transfers. These factors suggest there are many places where chemical or biological contaminants could be introduced into this supply chain. From the perspective of the United States, security throughout the Canadian system as well as the U.S. system is a concern, since cross-border traffic in these products is significant, with an average of about six million tonnes of grain products alone imported into the U.S. each year (USDA-FAS, 2003). Numerous interventions to enhance food safety and mitigate the risk of terrorism have been adopted or are in the process of being developed. Some of these are private initiatives and voluntary, as a component of firm-level security processes. Others are being adopted in response to legislated initiatives. The stakes are large, and there are likely to be substantial differences in costs and effectiveness of different approaches.

description: A safe and plentiful supply of surface water is crucial to the well-being of every resident of Alberta. The effective and efficient use of surface water is central to economic growth and environmental sustainability. As the necessary but competing demands on surface water intensify, the awareness of its limited supply increases. This is particularly evident in southern Alberta, which has experienced significant agricultural, industrial and population growth. In addition to its use for extensive irrigation, surface water in the South Saskatchewan River basin is vital to meet drinking and sanitation needs in rural and urban communities. Management of this key resource involves many researchable issues– water supply, water treatment, water distribution, wastewater collection and processing, flood control, navigation, hydropower production, aquatic recreation – which interact with each other and with government policies. The purpose of this article is to outline the priorities for socio-economic research on surface water resource issues in light of the ever-changing legal and policy frameworks in Alberta.

description: The neutron lifetime has been measured by comparing the decay rate with the reaction rate of $^3$He nuclei of a pulsed neutron beam from the spallation neutron source at the Japan Proton Accelerator Research Complex (J-PARC). The decay rate and the reaction rate were determined by simultaneously detecting electrons from the neutron decay and protons from the $^3$He(n,p)$^3$H reaction using a gas chamber of which working gas contains diluted $^3$He. The measured neutron lifetime was $898\,\pm\,10\,_{\rm stat}\,^{+15}_{-18}\,_{\rm sys}\,$s.
