Memory Effects in Nonequilibrium Transport for Deterministic Hamiltonian Systems

description: We consider nonequilibrium transport in a simple chain of identical mechanical cells in which particles move around. In each cell, there is a rotating disc, with which these particles interact, and this is the only interaction in the model. It was shown in \cite{eckmann-young} that when the cells are weakly coupled, to a good approximation, the jump rates of particles and the energy-exchange rates from cell to cell follow linear profiles. Here, we refine that study by analyzing higher-order effects which are induced by the presence of external gradients for situations in which memory effects, typical of Hamiltonian dynamics, cannot be neglected. For the steady state we propose a set of balance equations for the particle number and energy in terms of the reflection probabilities of the cell and solve it phenomenologically. Using this approximate theory we explain how these asymmetries affect various aspects of heat and particle transport in systems of the general type described above and obtain in the infinite volume limit the deviation from the theory in \cite{eckmann-young} to first-order. We verify our assumptions with extensive numerical simulations.

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The acceleration of charged particles at astrophysical collisionless shock waves is one of the best studied processes for the energization of particles to ultrarelativistic energies, required by multifrequency observations in a variety of astrophysical situations. In this paper we discuss some work aimed at describing one of the main progresses made in the theory of shock acceleration, namely the introduction of the non-linear backreaction of the accelerated particles onto the shocked fluid. The implications for the investigation of the origin of ultra high energy cosmic rays will be discussed.

description: The shift of the farm subsidies toward programs classified as being decoupled income supports in the WTO’s URAA raises the question of their true impact on production and trade. In this study, we measured the acreage effects of the Canadian whole farm programs under uncertainty. Based on the theoretical discussions regarding the role of the insurance effect in acreage decisions, we extend the theoretical restrictions examined by Chavas and Holt (1990)which enables us to include this effect in our model specification. Hence, we modified the expected utility maximization framework (under the hypothesis that farmers are risk averse) developed by Chavas and Holt (1990) and derived three distinct effects: market effects, the wealth effect, and the insurance effect.

description: Excerpts from the article: Since 1970, fewer people have been moving to the city, and increased numbers have been moving to rural (nonmetropolitan) America. For a few decades, however, population policy has focused on the problems of city growth, suburban expansion, and rural decline. Now, this new growth is bringing changes in rural land use, infrastructural development, social and medical services, and impacts on rural environment and ecology. In this article, we review these changes and discuss social, economic, and attitudinal explanations. Next, we analyze the role of residential preferences in decisions to migrate and the resulting policy implications.

description: We present a mechanism for dark matter (DM) production involving a self-interacting sector that at early times is ultra-relativistic but far-underpopulated relative to thermal equilibrium (such initial conditions often arise, e.g., from inflaton decay). Although elastic scatterings can establish kinetic equilibrium we show that for a broad variety of self-interactions full equilibrium is never established despite the DM yield significantly evolving due to $2\to k$ ($k>2$) processes (the DM carries no conserved quantum number nor asymmetry). During the active phase of the process, the DM to Standard Model temperature ratio falls rapidly, with DM kinetic energy being converted to DM mass, the inverse of the recently-discussed `cannibal DM mechanism'. Potential observables and applications include self-interacting DM signatures in galaxies and clusters, dark acoustic oscillations, the alteration of free-streaming constraints, and possible easing of $σ_8$ and Hubble tensions.

description: Our study of the evolution of transmission eigenvalues, due to changes in various physical parameters in a disordered region of arbitrary dimensions, results in a generalization of the celebrated DMPK equation. The evolution is shown to be governed by a single complexity parameter which implies a deep level of universality of transport phenomena through a wide range of disordered regions. We also find that the interaction among eigenvalues is of many body type that has important consequences for the statistical behavior of transport properties.

$μ\to e γ$ selecting scalar leptoquark solutions for the $(g-2)_{e,μ}$ puzzles

description: We investigate all potentially viable scenarios that can produce the chiral enhancement required to simultaneously explain the $(g-2)_{e}$ and $(g-2)_μ$ data with either a single scalar leptoquark or a pair of scalar leptoquarks. We provide classification of these scenarios in terms of their ability to satisfy the existing limits on the branching ratio for the $μ\to e γ$ process. The simultaneous explanation of the $(g-2)_{e,μ}$ discrepancies, coupled with the current experimental data, implies that the $(g-2)_e$ loops are exclusively due to the charm quark propagation whereas the $(g-2)_μ$ loops are due to the top quark propagation. The scenarios where the $(g-2)_e$ loops are due to the top (bottom) quark propagation are, at best, approximately nine (three) orders of magnitude away from the experimental limit on the $μ\to e γ$ branching ratio. All in all, there are only three particular scenarios that can pass the $μ\to e γ$ test and simultaneously create large enough impact on the $(g-2)_{e,μ}$ discrepancies when the new physics is based on the Standard Model fermion content. These are the $S_1$, $R_2$, and $S_1 \& S_3$ scenarios, where the first two are already known to be phenomenologically viable candidates with respect to all other flavor and collider data constraints. We show that the third scenario, where the right-chiral couplings to charged leptons are due to $S_1$, the left-chiral couplings to charged leptons are due to $S_3$, and the two leptoquarks mix through the Standard Model Higgs field, cannot address the $(g-2)_{e}$ and $(g-2)_μ$ discrepancies at the $1σ$ level due to an interplay between $K_L^0 \to e^\pm μ^\mp$, $Z \to e^+ e^-$, and $Z \to μ^+ μ^-$ data despite the ability of that scenario to avoid the $μ\to e γ$ limit.

description: Two-dimensional transition metal dichalcogenides (TMDs) have been attracting significant interest due to a range of properties, such as layer-dependent inversion symmetry, valley-contrasted Berry curvatures, and strong spin-orbit coupling (SOC). Of particular interest is niobium diselenide (NbSe2), whose superconducting state in few-layer samples is profoundly affected by an unusual type of SOC called Ising SOC. Combined with the reduced dimensionality, the latter stabilizes the superconducting state against magnetic fields up to ~35 T and could lead to other exotic properties such as nodal and crystalline topological superconductivity. Here, we report transport measurements of few-layer NbSe$_2$ under in-plane external magnetic fields, revealing an unexpected two-fold rotational symmetry of the superconducting state. In contrast to the three-fold symmetry of the lattice, we observe that the magnetoresistance and critical field exhibit a two-fold oscillation with respect to an applied in-plane magnetic field. We find similar two-fold oscillations deep inside the superconducting state in differential conductance measurements on NbSe$_2$/CrBr$_3$ superconductor-magnet junctions. In both cases, the anisotropy vanishes in the normal state, demonstrating that it is an intrinsic property of the superconducting phase. We attribute the behavior to the mixing between two closely competing pairing instabilities, namely, the conventional s-wave instability typical of bulk NbSe$_2$ and an unconventional d- or p-wave channel that emerges in few-layer NbSe2. Our results thus demonstrate the unconventional character of the pairing interaction in a few-layer TMD, opening a new avenue to search for exotic superconductivity in this family of 2D materials.

description: Functioning and development of municipalities are usually based on their economic and social potentials. Further sustainable development of municipalities implies enhancing and perfecting the existing potentials. For this purpose, complex development programs for existing social-economic potentials are being elaborated in most municipalities. The next step will often be the formulating of certain tasks for the development of functioning potentials of the municipalities. Meanwhile, the set of certain tasks mostly depends on the state of certain components of the potentials, including labour forces, material and technical resources, the municipality’s ground environment, information and innovation flows, financial resources, and natural wealth and ecological resources. The management system aiming at raising efficiency of municipalities should include the economic interest balance mechanism. Today visions of the development of production and social potentials of municipalities in the current conditions imply the modernization of their tax system, and a significant increase of financing of certain investment projects as well.

description: This paper is about aging and the ability to perform under pressure on the PGA tour. Performance increases with golfing skill, but may first increase and then decrease with age as experience interacts with changes in physical condition. Similarly, mental fortitude or the ability of a golfer to perform under pressure may first increase and then decrease with age as experience interacts with changes in the ability to concentrate. Net performance on the tour is the result of both physical golfing skill and the ability to perform under pressure. We control for changes in physical skill and focus on the mental side of the game. The role of experience suggests an inverted U shaped relationship between age and mental performance that could vary significantly across golfers. We use Order-m FDH to calculate a measure of performance under pressure, and we confirm an inverted U-shaped curve with age. Along the way, we examine the ability to perform under pressure at the level of the individual golfer.

description: We describe a rigorous construction, using matched asymptotic expansions, which establishes under very general conditions that local terrestrial and solar-system experiments will measure the effects of varying `constants' of Nature occurring on cosmological scales to computable precision. In particular, `constants' driven by scalar fields will still be found to evolve in time when observed within virialised structures like clusters, galaxies, and planetary systems. This provides a justification for combining cosmological and terrestrial constraints on the possible time variation of many assumed `constants' of Nature, including the fine structure constant and Newton's gravitation constant.

Acknowledging home(s) and belonging(s) : border writing
Creators: name: Purru, Kadi
Publisher: name: University of British Columbia
Year: 2009

description: My dissertation is an inquiry into issues of home and belonging. For many people, the struggle to create a home in a "new" country, and the oscillation between a past "there" and present "here" have become ways of existence. Displacement challenges and raises questions regarding one's roots, affiliations, loyalty and belonging. The yearning for a place such as home becomes a site of inquiry for communities of displaced people. Destined to live between languages, cultures and national affiliations, im/migrants construct their homes in the particular place of "border." Acknowledging Home(s) and Belonging(s): Border Writing is "homeward" journeying through the discursive landscapes of nation, ethnicity, diaspora, and "race." It explores how border interrupts/initiates a discourse of home. I am an im/migrant researcher. The word "migrant" connotes impermanence, detachment and instability. From this positionality I introduce a slash into the word "immigrant" to transform these connotations into a permanence of migration. As autoethnographic and conversational inquiry, I explore im/migrant experiences from the position of "I," rather than "We." However, "I" is not a position of isolated individual(istic) exclusiveness, but a position of the personal articulation through the relationships with/in community. My research includes conversations with: theorists, colleagues from different disciplinary backgrounds, members of the "ethnic" communities to which I belong, and my daughter. I construct these conversations as borderzone arriculations where a "third space" emerges. The word dissertation stems etymologically from Greek dialegesthai, to converse, to dialogue; whereby dia- means "one with another," and legesthai means "to tell, talk." My dissertation endeavors to recognize - to know again, to know anew these deep layers of border as dialogue and conversation. As an im/migrant inquiry, my dissertation intends to create a different, mother knowing and culture of scholarship that broaden and deepen the space of academic researching/writing.

description: Over the recent years, various deep learning-based embedding methods have been proposed and have shown impressive performance in speaker verification. However, as in most of the classical embedding techniques, the deep learning-based methods are known to suffer from severe performance degradation when dealing with speech samples with different conditions (e.g., recording devices, emotional states). In this paper, we propose a novel fully supervised training method for extracting a speaker embedding vector disentangled from the variability caused by the nuisance attributes. The proposed framework was compared with the conventional deep learning-based embedding methods using the RSR2015 and VoxCeleb1 dataset. Experimental results show that the proposed approach can extract speaker embeddings robust to channel and emotional variability.

A saddle-point approximation is developed which relates this problem to a variational principle. Several examples are worked out in detail.

description: Strain at surfaces and interfaces play an important role in the optical and electronic properties of materials. MeV ion-induced strain determination in single crystal silicon substrates and in Ag (nanoisland)/Si(111) at surface and interfaces has been carried out using transmission electron microscopy (TEM) and surface-sensitive X-ray diffraction. Ag nanoislands are grown under various surface treatments using thermal evaporation in high vacuum conditions. Irradiation has been carried out with 1.5 MeV Au^{2+} ions at various fluences and impact angles. Selected area electron diffraction (SAED) and lattice imaging (using TEM) has been used to determine the strain at surface and interfaces. Preliminary results on the use of surface-sensitive asymmetric x-ray Bragg reflection method have been discussed. The TEM results directly indicate a contraction in the silicon lattice due to ion-induced effects. The nanoislands have shadowed the ion beam resulting in lesser strain beneath the island structures in silicon substrates. High-resolution lattice imaging has also been used to determine the strain in around amorphization zones caused by the ion irradiation.

description: The combination of high optical nonlinearity in the electromagnetically induced transparency (EIT) effect and strong electric dipole-dipole interaction (DDI) among the Rydberg-state atoms can lead to important applications in quantum information processing and many-body physics. One can utilize the Rydberg-EIT system in the strongly-interacting regime to mediate photon-photon interaction or qubit-qubit operation. One can also employ the Rydberg-EIT system in the weaklyinteracting regime to study the Bose-Einstein condensation of Rydberg polaritons. Most of the present theoretical models dealt with the strongly-interacting cases. Here, we consider the weaklyinteracting regime and develop a mean field model based on the nearest-neighbor distribution. Using the mean field model, we further derive the analytical formulas for the attenuation coefficient and phase shift of the output probe field. The predictions from the formulas are consistent with the experimental data in the weakly-interacting regime, verifying the validity of our model. As the DDI-induced phase shift and attenuation can be seen as the consequences of elastic and inelastic collisions among particles, this work provides a very useful tool for conceiving ideas relevant to the EIT system of weakly-interacting Rydberg polaritons, and for evaluating experimental feasibility.

description: Recent studies that compare the efficiency and distributional impacts of alternative instruments to curb sprawl typically ignore what to do with the revenues from anti-sprawl policies, such as development taxes. This paper extends first-best analysis of development taxes aimed at preserving land at the urban fringe to account for interactions with other distortions within the urban system. By incorporating urban decline at the city core, which in turn, generates negative neighborhood spillover effects and extra pressure for development at the urban fringe, we provide a more complete framework to evaluate the efficiency and distributional impacts of development taxes. We consider three potential alternative schemes to recycle the revenues: lump sum recycling, earmarked revenues to purchase conservation easements that permanently save open space and earmarked revenues to subsidize a revitalization program at the city core. In this setting, when revenues from the development tax are earmarked to fund a conservation easement there is an additional welfare gain (relative to the lump sum case) because the threat of future conversation of open space is fully eliminated. Similarly, when revenues are earmarked to fund a revitalization program at the city core, there are additional sources of welfare that make this policy preferred relative to the lump-sum recycling scheme. Finally, we also explore the spatial distributional impacts of these three alternative recycling schemes.
Globalization, Growth and Distribution: Framing The Questions

description: In the last two decades, across a range of countries high growth rates have reduced poverty but have been accompanied by rising inequality. This paper is motivated by this stylized fact, and by the strong distributional concerns that persist among populations and policy makers alike, despite the poverty reduction observed in official statistics where growth has been sufficiently high. This seeming disconnect frames the questions posed in this paper. Why the disconnect, and what to do about it? It is argued that official poverty statistics may be missing key elements of the ground level reality of distributional evolution, of which rising inequality may be an indirect indicator. Heterogeneity of population means that there may be significant numbers of poor losers from technical change, economic reform and global integration, even when overall measured poverty falls. In terms of actions, attention is drawn to the role of safety nets as generalized compensation mechanisms, to address the ethical and political economy dimensions of such a pattern of distributional evolution. Addressing structural inequalities is also a long term answer with payoffs in terms of equitable growth. In terms of future analysis, diminishing returns have set in to the inequality-growth cross-country regressions literature. Further work to help policy makers should focus on (i) new information to illuminate the disconnect, (ii) analysis and assessment of safety nets as generalized compensation mechanisms, and (iii) addressing specific forms of structural inequality related to assets, gender, and social groupings like caste or ethnicity.

description: The eruption of V4332 Sgr discovered in February 1994 shows striking similarities to that of V838 Mon started in January 2002. The nature of these eruptions is, however, enigmatic and unclear. We present new photometric and spectroscopic data on V4332 Sgr obtained in April-May 2003 at the SAAO. The obtained spectrum shows an unusual emission-line component superimposed on an early M-type stellar spectrum. The emission-line spectrum is of very low excitation and is dominated by lines from neutral elemets (NaI, FeI, CaI) and molecular bands (TiO, ScO, AlO). We also analyse all the observational data, mainly photometric measurements, available for V4332 Sgr. This allows us to follow the evolution of the effective temperature, radius and luminosity of the object since February 1994 till 2003. We show that the observed decline of V4332 Sgr can be accounted for by a gravitational contraction of an inflated stellar envelope. The combined optical and infrared photometry in 2003 shows that apart from the M-type stellar component there is a strong infrared excess in the KLM bands. This excess was absent in the 2MASS measurements done in 1998 but was probably starting to appear in K in 1999 when the object was observed in the DENIS survey. We interpret the results in terms of a stellar merger scenario proposed by Soker & Tylenda. The infrared excess is likely to be due to a disc-like structure which is either of protostellar nature or has been produced during the 1994 eruption and stores angular momentum from the merger event.

description: The basic aim is to extend some results and concepts of non-autonomous second order differential systems with convex potentials to the new context of multi-time Poisson-gradient PDE systems with convex potential. In this sense, we prove that minimizers of a suitable action functional are multiple periodical solutions of a Dirichlet problem associated to the Euler-Lagrange equations. Automatically, these are solutions of the associated multi-time Hamiltonian equations.

description: The Banfi-Marchesini-Smye (BMS) equation accounts for non-global logarithms to all orders in perturbation theory in the large-Nc approximation. We show that the squared amplitudes for the emission of soft energy-ordered gluons are correctly embedded in this equation, and explicitly verify that they coincide with those derived in our previous work in the large-Nc limit up to sixth order in the strong coupling. We perform analytical calculations for the non-global logarithms up to fourth order for the specific hemisphere mass distribution in e+ e- collisions, thus confirming our previous semi-numerical results. We show that the solution to the BMS equation may be cast into a product of an infinite number of exponentials each of which resums a class of Feynman diagrams that manifest a symmetry pattern, and explicitly carry out the computation of the first of these exponentials.

Systems in tension : perceptions of business and education in partnership

description: The aim of this research project has been to map the range of perceptions that a small sample of educators, business representatives and students, drawn from communities situated around an urban center in western Canada, have of the nature of business and education as well as business-education partnerships. Through an analysis of these perceptions, this work is intended to develop a framework for the study of these partnerships in the future, and in the development or avoidance of such partnerships by the potential participants in them. From the range of perceptions held by the participants in this dissertation, we can conclude that partnering is not a simple matter of two parties agreeing to some workable union between them for mutual benefits. Yet, despite many benefits accrued, partnerships are troublesome arrangements. Business and education systems are comprised of factors, including participants' perceptions of the purposes, form and structure of education, that influence both the approach to, and the set up of, partnership arrangements. The difficulty of business-education partnerships is far more complex than questionable business motives and practices. From the perceptions of the participants in this study it is evident that education alone in partnerships is a matter interpreted differently by its various stakeholders and practitioners. I am not suggesting that these perceptions are generalizeable to a larger population, but the perceptions of this group present what I would argue are effective examples of how there can be points of divergence and convergence among the participants in business-education partnerships, and how the fundamental and significant nature of those points can provide the basis of a breakdown or the development of such partnerships. A greater understanding of these points of view and the factors highlighted by the participants arguably provide the best starting place for dialogue between business and education about partnering benefits, drawbacks and possibilities. And finally I suggest that systemic thinking principles be used to coordinate these viewpoints and make for collaboration, and not merely sufferance.

description: This paper addresses the potential effects of world agricultural trade liberalization on poverty and regional income distribution in Brazil, using an inter-regional applied general equilibrium (AGE) and a micro-simulation model of Brazil tailored for income distribution and poverty analysis by using a detailed representation of households. The model distinguishes 10 different labor types and has 270 different household expenditure patterns. Income can originate from 41 different production activities located in 27 different regions in the country. The AGE model communicates to a micro-simulation model that has around 112,000 Brazilian households and 264,000 adults. Poverty and income distribution indices are computed over the entire sample of households and persons, before and after the policy shocks. The simulated trade liberalization scenario causes agriculture to expand considerably and so, given the importance that agriculture still has for the poorest in Brazil, it has positive impacts on poverty in Brazil. The only states which show an increase in the number of poor households are Sao Paulo and Rio de Janeiro, where the bulk of the manufacturing activities in Brazil are concentrated. There is an even more positive impact on inequality. The higher fall in the poverty gap is shown to occur mainly on the poorest household groups, suggesting that the poorest among Brazil’s poor would benefit more from global trade liberalization.
ON A CLASS OF DERIVATIVE NONLINEAR SCHRODINGER-TYPE EQUATIONS IN TWO SPATIAL DIMENSIONS

description: We present analytical results and numerical simulations for a class of nonlinear dispersive equations in two spatial dimensions. These equations are of (derivative) nonlinear Schrödinger type and have recently been obtained by Dumaset al.in the context of nonlinear optics. In contrast to the usual nonlinear Schrödinger equation, this new model incorporates the additional effects of self-steepening and partial off-axis variations of the group velocity of the laser pulse. We prove global-in-time existence of the corresponding solution for various choices of parameters. In addition, we present a series of careful numerical simulations concerning the (in-)stability of stationary states and the possibility of finite-time blow-up.

description: Background: Professionals’ personal perceptions of sedated patients in the context of palliative care may influence their opinion on sedation as treatment option. However, little is known of palliative care professionals’ perception of patients dying under sedation. Aim: To explore German specialist palliative care team members’ views on and perception of the dying process under sedation. Design: Qualitative phenomenological study using semi-structured interviews (n = 59). Interviews took place in-person after recruitment via a contact person and were transcribed verbatim. Framework Analysis was used for analysis. Setting/participants: Physicians, nurses, psychologists, physical therapists, chaplains, and social workers from 10 palliative care units and 7 specialist palliative homecare teams across 12 German cities. Results: Participants’ views on patients dying under sedation can be grouped into: (i) those who perceived an influence of sedation on the dying process with and without positive and/or negative connotations and (ii) those who saw no difference between dying with or without sedation. Positive connotations referred to the perception of sedation providing an easier path. Concerns were mainly related to the deprivation of patients regarding a conscious dying. The metaphorical description of sedation as “sleep” was common among participants. Conclusions: The wide range of perceptions of patients dying under sedation may be rooted in different judgements regarding aspects of a good death. Clarifying ideals of a good death with professionals, patients, and relatives before sedation may support transparent decision-making and help avoid conflicts or moral distress.
