description: Conditional and Lie symmetries of semi-linear 1D Schrödinger and diffusion equations are studied if the mass (or the diffusion constant) is considered as an additional variable. In this way, dynamical symmetries of semi-linear Schrödinger equations become related to the parabolic and almost-parabolic subalgebras of a three-dimensional conformal Lie algebra conf_3. We consider non-hermitian representations and also include a dimensionful coupling constant of the non-linearity. The corresponding representations of the parabolic and almost-parabolic subalgebras of conf_3 are classified and the complete list of conditionally invariant semi-linear Schrödinger equations is obtained. Possible applications to the dynamical scaling behaviour of phase-ordering kinetics are discussed.

description: Export subsidies and price transparency will be areas of critical importance in the forthcoming round of World Trade Organization (WTO) negotiations. This paper provides a review and discussion of issues relating to export subsidies and transparency in international wheat trade. Among other topics, the paper addresses the escalation in U.S. and EU producer subsidy equivalents (PSEs) for wheat since 1996, EU export restitutions, export credit guarantee programs, and price transparency and price discrimination, specifically as they relate to State Trading Enterprises (STEs). As the United States develops its strategy for trade negotiations, several points should be considered. First, the European Union continues to subsidize its wheat much more intensively than other wheat exporters. EU export restitutions overshadow most of the other `policy distortions' which might be drawn into negotiations over wheat trade. Second, there will likely be pressure for new international disciplines on export credit guarantee programs. This is of critical significance for the United States, given the recent importance of sales under GSM programs, and features which may make these programs more effective than those employed by competing exporters. U.S. wheat producers would lose if the United States were forced to curtail its use of export credit guarantees. Conceptually, the topic of price transparency can be understood in the context of bidding games with asymmetric information. As such, it probably is not of great significance to international trade; for example, `lack of transparency' (e.g., by the Canadian Wheat Board) may impute an advantage of less than $1-2/mt in bidding competition. Lack of transparency is also linked to concerns about hidden subsidies and the potential for evading international disciplines. Past investigations of the Canadian Wheat Board have turned up little evidence of unfair pricing, while highlighting the difficulty of defining `cost of acquisition' where Board transactions are concerned. Finally, while an ability to practice price discrimination is an advantage enjoyed by STEs, that is not prohibited under the WTO.

description: High-frequency long-baseline experiments with the Atacama Large Millimeter/submillimeter Array were organized to test the high angular resolution imaging capabilities in the submillimeter wave regime using baselines up to 16 km. Four experiments were conducted, two Band 7 (289 GHz) and two Band 8 (405 GHz) observations. Phase correction using band-to-band (B2B) phase referencing was used with a phase calibrator only 0.7deg away observed in Band 3 (96 GHz) and Band 4 (135 GHz), respectively. In Band 8, we achieved the highest resolution of 14x11 mas. We compared the synthesis images of the target quasar using 20 and 60 s switching cycle times in the phase referencing. In Band 7, the atmosphere had good stability in phase rms (<0.5 rad over 2 minutes), and there was little difference in image coherence between the 20 and 60 s switching cycle times. One Band 8 experiment was conducted under a worse phase rms condition (>1 rad over 2 minutes), which led to a significantly reduced coherence when using the 60 s switching cycle time. One of our four experiments indicates that the residual phase rms error after phase referencing can be reduced to 0.16 rad at 289 GHz in using the 20 s switching cycle time. Such conditions would meet the phase correction requirement of image coherence of >70% in Band 10, assuming a similar phase calibrator separation angle, emphasizing the need for such B2B phase referencing observing at high frequencies.

description: The dynamics of accretion discs around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper we generalise the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz et al.(1978) by including strong toroidal magnetic field and construct analytic solutions for barotropic tori with constant angular momentum. This development is particularly important for the general relativistic computational magnetohydrodynamics that suffers from the lack of exact analytic solutions that are needed to test computer codes.

Layered Dynamical Conductivity for a Transfer Matrix Method -- Application to an N-layer Graphene

description: We calculated the optical properties of an $N$-layer graphene by formulating the dynamical conductivity of each layer. This is the conductivity when an electromagnetic field is localized at a particular layer and differs from the standard conductivity calculated assuming a uniform field throughout all layers. By combining these conductivities with a transfer matrix method, we took into account the spatial variation of the electromagnetic field caused by internal reflections. The results obtained from the two conductivities show that similar peak structures originating from the interlayer electronic interaction appear in reflectance of an $N$-layer graphene at any $N$. The peak is inherent to the AB stacking and is not seen for the AA stacking, and the peak corresponding to a sufficiently large $N$ is considered to the one observed for natural graphite. We also gave physical explanations of the existing experimental results on highly oriented pyrolytic graphite and natural graphite under high pressure. Although a layered conductivity underestimates the reflectance of graphite at photon energies below the peak, we will show that the disagreement is attributed to a nonlocal conductivity caused by interlayer interaction. The calculations with layered conductivity are useful in knowing the local response to light and may be further validated by an observation of a correction by interlayer electronic interaction to the universal layer number that we have discovered recently.

description: Breast cancer accounts for over 15% of cancer mortalities in women, and late-stage breast cancer is currently considered incurable. Peptide-drug conjugates were developed that specifically target the human Y1 receptor, a receptor that is overexpressed in breast cancer cells. These conjugates utilised the toxic drug camptothecin as well as radioactive lutetium-177 to treat cancer cells, with cellular assays finding that the conjugates were highly selective and effective at killing cancer cells in low concentrations, despite some issues with stability in cell media. These studies are encouraging for further development and testing in animal models.

description: In the present paper, we use the holographic approach to describe the early-time acceleration and the late-time acceleration eras of our Universe in a unified manner. Such ``holographic unification'' is found to have a correspondence with various higher curvature cosmological models with or without matter fields. The corresponding holographic cut-offs are determined in terms of the particle horizon and its derivatives, or the future horizon and its derivatives. As a result, the holographic energy density we propose is able to merge various cosmological epochs of the Universe from a holographic point of view. We find the holographic correspondence of several $F(R)$ gravity models, including axion-$F(R)$ gravity models, of several Gauss-Bonnet $F(G)$ models and finally of $F(T)$ models, and in each case we demonstrate that it is possible to describe in a unified way inflation and late-time acceleration in the context of the same holographic model.

description: There is a class of quantum Hamiltonians known as Rokhsar-Kivelson(RK)-Hamiltonians for which static ground state properties can be obtained by evaluating thermal expectation values for classical models. The ground state of an RK-Hamiltonian is known explicitly, and its dynamical properties can be obtained by performing a classical Monte Carlo simulation. We discuss the details of a Diffusion Monte Carlo method that is a good tool for studying statics and dynamics of perturbed RK-Hamiltonians without time discretization errors. As a general result we point out that the relation between the quantum dynamics and classical Monte Carlo simulations for RK-Hamiltonians follows from the known fact that the imaginary-time evolution operator that describes optimal importance sampling, in which the exact ground state is used as guiding function, is Markovian. Thus quantum dynamics can be studied by a classical Monte Carlo simulation for any Hamiltonian that is free of the sign problem provided its ground state is known explicitly.

description: The psychology, the marketing consumer behavior and, to a much smaller extent, the economics literature have long reported evidence that decision makers utilize different decision strategies depending upon many factors (person-specific, task-specific, etc.). Such observations have generally failed to affect the specification of choice models in commercial practice and academic research, both of which still tend to assume an utility maximizing, full information, indefatigable decision maker. This is true whether the models deal with Stated Preference (SP - from hypothetical elicitations) or Revealed Preference (RP - from actual market decisions) choice data. This paper, which deals only with SP data, addresses the following issues: (1) does task complexity affect decision strategy selection in experimental choice tasks? (2) does the cumulative cognitive burden created by multiple choice scenarios done in sequence affect the selection of decision strategy by respondents? Our contribution is two-fold: (1) we introduce decision strategy selection as an explicit factor in aggregate choice models via the mechanism of latent classes, which are assumed to be a function of task complexity; (2) we demonstrate, for a particular set of data, that within the scope of an SP choice task, respondents did indeed make use of multiple decision strategies as choice set complexity changed and as the SP task progressed. We examine the import of our findings to current practice, model interpretation and future research needs.

description: Here we build some effective boundary conditions to be used in numerical calculations in order to avoid the thin meshing usually required in problems involving Hartmann layers near a locally plane wall. Wall model are provided for both tangential and normal electric current density and velocity. In particular, a condition on the normal derivative of the tangential velocity is derived. A wide variety of problems is covered as the only restriction is that the magnetic Reynolds number has to be large at the scale of the Hartmann layer. The cases of perfectly conducting or insulating wall are examined, as well as the case of a thin conducting wall. The newest result is a condition on the normal velocity accounting for inertial effects in the Hartmann layer.

description: Let $Φ(x,y)\in\mathbb{C}[x,y]$ be a symmetric polynomial of partial degree $d$. The graph $G(Φ)$ is defined by taking $\mathbb{C}$ as set of vertices and the points of $\mathbb{V}(Φ(x,y))$ as edges. We study the following problem: given a finite, connected, $d$-regular graph $H$, find the polynomials $Φ(x,y)$ such that $G(Φ)$ has some connected component isomorphic to $H$ and, in this case, if $G(Φ)$ has (almost) all components isomorphic to $H$. The problem is solved by associating to $H$ a characteristic ideal which offers a new perspective to the conjecture formulated in a previous paper, and allows to reduce its scope. In the second part, we determine the characteristic ideal for cycles of lengths $\le 5$ and for complete graphs of order $\le 6$. This results provide new evidence for the conjecture.

description: It has been a significant challenge to portray intraclass disparity precisely in the area of activity recognition, as it requires a robust representation of the correlation between subject-specific variation for each activity class. In this work, we propose a novel end-to-end knowledge directed adversarial learning framework, which portrays the class-conditioned intraclass disparity using two competitive encoding distributions and learns the purified latent codes by denoising learned disparity. Furthermore, the domain knowledge is incorporated in an unsupervised manner to guide the optimization and further boosts the performance. The experiments on four HAR benchmark datasets demonstrate the robustness and generalization of our proposed methods over a set of state-of-the-art. We further prove the effectiveness of automatic domain knowledge incorporation in performance enhancement.
Foreground Speech Robustness of DNN-based Acoustic Scene Classification
Creators: name: Song, Siyuan

Publisher: name: Zenodo
Year: 2023

description: The characterising sound of the Acoustic Scene Classification (ASC) system is background noise while the system performance is strongly affected by foreground speech. Previously, based on the iVector framework, we proposed different strategies to increase the system robustness when foreground speech is present. We, here, extend these methods to the deep learning based ASC system for improving foreground speech robustness. The ResNet system with low and high complexities is proposed as the baseline to explore the influence of proposed methods, in which the training dataset is adapted to multi-condition training with different signal-to-background ratios (SBRs). We investigate the noise-floor-based Mel-FilterBank Energies (NF-MFBE) as the input feature of the ResNet system, which brings different effects to models of different complexities. In addition, speech presence information is incorporated in ASC frameworks with the cooperation of a speech enhancement (SE) system - cruse-net. A frame-level speech mask is provided for each utterance in order to show the scene-related importance of each frame. For further improvement, ensemble methods to integrate classification scores from different models are introduced. Experiment results show that with the proposed meta-learner combining the results of ResNet models with different input features, the classification accuracy is improved in all tested SBRs.

description: The acceleration of polarized electrons, positrons, protons and ions in strong laser and plasma fields is a very attractive option to obtain polarized beams in the multi-MeV range. Recently, there has been substantial progress in the understanding of the dominant mechanisms leading to high degrees of polarization, in the numerical modelling of these processes and in their experimental implementation. This review article presents an overview on the current status of the field, on the concepts of polarized laser-plasma accelerators and of the beam polarimetry.

description: This study examined rural Ugandan women's lives to discover reasons why they may or may not practice agroforestry. These women are responsible for the triple roles of reproduction, production and community maintenance work, all carried out within the context of a gendered social environment. From the perspective of the social manifestations of gender, six key factors were identified. The findings were used to create a theoretical model of the interaction between rural women's lives and agroforestry systems. The model shows that agroforestry is not only a biophysical farming system; There is a human component in that interacts with other components to determine the success or failure of an agroforestry initiative. The model can be used to identify and understand the human component of the agroforestry system on an individual and community level.

In this way, we are able to obtain high quality audio source separation with limited number of floating point operations, memory requirements, number of parameters and latency. Our experiments on both speech and environmental sound separation datasets show that SuDoRMRF performs comparably and even surpasses various state-of-the-art approaches with significantly higher computational resource requirements.

description: Using archival data of low-redshift (z < 0.01) Type Ia supernovae (SN Ia) and recent observations of high-redshift (0.16 < z <0.64; Matheson et al. 2005) SN Ia, we study the "uniformity'' of the spectroscopic properties of nearby and distant SN Ia. We find no difference in the measures we describe here. In this paper, we base our analysis solely on line-profile morphology, focusing on measurements of the velocity location of maximum absorption (vabs) and peak emission (vpeak). We find that the evolution of vabs and vpeak for our sample lines (Ca II 3945, Si II 6355, and S II 5454, 5640) is similar for both the low- and high-redshift samples. We find that vabs for the weak S II 5454, 5640 lines, and vpeak for S II 5454, can be used to identify fast-declining [dm15 > 1.7] SN Ia, which are also subluminous. In addition, we give the first direct evidence in two high-z SN Ia spectra of a double-absorption feature in Ca II 3945, an event also observed, though infrequently, in low-redshift SN Ia spectra (6/22 SN Ia in our local sample). We report for the first time the unambiguous and systematic intrinsic blueshift of peak emission of optical P-Cygni line profiles in Type Ia spectra, by as much as 8000 km/s. All the high-z SN Ia analyzed in this paper were discovered and followed up by the ESSENCE collaboration, and are now publicly available.

description: A number of observations hints for the presence of an intermediate mass black hole (IMBH) in the core of three globular clusters: M15 and NGC 6752 in the Milky Way, and G1, in M31. However the existence of these IMBHs is far form being conclusive. In this paper, we review their main formation channels and explore possible observational signs that a single or binary IMBH can imprint on cluster stars. In particular we explore the role played by a binary IMBH in transferring angular momentum and energy to stars flying by.

description: The responses of a random sample of consumers to the use of bovine somatotrophin (BST) in milk production were elicited using a stated preference methodology. A multinomial logit model of consumer choice was developed and tested to analyse consumers' choices of milk with varying characteristics of fat content, price, freshness and BST treatment. Welfare calculations for a representative consumer indicate welfare losses with the introduction of BST which are not fully offset by preferred milk attributes such as reduced price or increased freshness levels. Welfare losses were slightly less for a male than a female consumer and were less for consumers with higher levels of income and education. Losses were greatest when a representative consumer was denied the option of choosing not to purchase milk. There was a small welfare gain when the representative consumer was offered a full range of "BST" and "non-BST" milks. The results suggest that making appropriately labelled "BST-free" milk available to consumers could decrease consumer welfare losses associated with the introduction of BST in Canada.

description: We study the formation of disks via the cooling flow of gas within galactic haloes using smoothed particle hydrodynamics simulations. These simulations resolve mass scales of a few thousand solar masses in the gas component for the first time. Thermal instabilities result in the formation of numerous warm clouds that are pressure confined by the hot ambient halo gas. The clouds fall slowly onto the disk through non-spherical accretion from material flowing preferentially down the angular momentum axis. The rotational velocity of the infalling cold gas decreases as a function of height above the disk, closely resembling that of the extra-planar gas recently observed around the spiral galaxy NGC 891.

description: Rates of aggregation of dodecane-in-water (d/w) nanoemulsions stabilized with 7.5 mM sodium dodecylsulfate (SDS) are evaluated beyond 500 mM NaCl. As in the case of hexadecane-in-water (h/w) emulsions, it is found that flocculation rates apparently decrease with the ionic strength, departing appreciably from theoretical predictions. Since many-particle simulations proved to be very time consuming, an accurate knowledge of experimental parameters is necessary prior to the realization of further evaluations. Here, the change in the viscosity of the aqueous solution due to the surfactant phase behavior is considered as a possible cause of referred phenomenon. The influence of the external viscosity on the outcome of the simulations is appraised using a quotient between the actual viscosity of the surfactant solution at a given salt concentration and its value in the absence of salt. For that purpose, the viscosity of 0.5 and 7.5 mM SDS solutions was measured between 300 an 900 mM NaCl for temperatures of 20 and 25 °C. It is concluded that the augment of the aqueous viscosity due to the formation of surfactant crystals diminish significantly the aggregation rate. Yet this decline seems insufficient to justify the observed reduction of kFC at 25 C. Nevertheless, it is noteworthy that a 5-degree change in the temperature of the surfactant solution causes a remarkable decrease of kFC . Additionally, a set of two-particle simulations is used here to illustrate the limitations of this methodology for the appraisal of the viscosity contribution. It is confirmed that such approach is only convenient to study the effect of the interaction potential on the aggregation rate, as it was formerly conceived by Fuchs [1936].

description: We show that thermalization of the motion of atoms at negative temperature is possible in an optical lattice, for conditions that are feasible in current experiments. We present a method for reversibly inverting the temperature of a trapped gas. Moreover, a negative-temperature ensemble can be cooled, reducing abs(T), by evaporation of the lowest-energy particles. This enables the attainment of the Bose-Einstein condensation phase transition at negative temperature.

description: Collisionless, cold dark matter in the form of weakly-interacting massive particles (WIMPs) is well-motivated in particle physics, naturally yields the observed relic density, and successfully explains structure formation on large scales. On small scales, however, it predicts too much power, leading to cuspy halos, dense cores, and large numbers of subhalos, in apparent conflict with observations. We consider superWIMP dark matter, produced with large velocity in late decays at times 10^5 s - 10^8 s. As analyzed by Kaplinghat in a more general setting, we find that superWIMPs have sufficiently large free-streaming lengths and low phase space densities to help resolve small scale structure problems while preserving all of the above-mentioned WIMP virtues.

description: To reduce the potential for response bias on the follow-up bid in multiple-bound discrete choice CVM questions while maintaining much of the efficiency gains of the multiple-bound approach, we introduce the one-and-one-half-bound (OOHB) approach. Despite the fact that the OOHB model uses less information than the double-bound (DB) approach, efficiency gains in moving from single-bound to OOHB capture a large portion of the gain associated with moving from single-bound to DB. In an analysis of survey data, our OOHB estimates demonstrated higher consistency with respect to the follow-up data than the DB estimates and were more efficient as well.

Level density of a Fermion gas: average growth, fluctuations, universality

description: It has been shown by H. Bethe more than 70 years ago that the number of excited states of a Fermi gas grows, at high excitation energies $Q$, like the exponential of the square root of $Q$. This result takes into account only the average density of single particle (SP) levels near the Fermi energy. It ignores two important effects, namely the discreteness of the SP spectrum, and its fluctuations. We show that the discreteness of the SP spectrum gives rise to smooth finite--$Q$ corrections. Mathematically, these corrections are associated to the problem of partitions of an integer. On top of the smooth growth of the many--body density of states there are, generically, oscillations. An explicit expression of these oscillations is given. Their properties strongly depend on the regular or chaotic nature of the SP motion. In particular, we analyze their typical size, temperature dependence and probability distribution, with emphasis on their universal aspects.

description: A flexible, full rank two model of food consumption that is globally consistent with economic theory, aggregates across income, demographic variables, and variations in micro demand parameters, and accommodates tradeoffs between tastes and nutrition is derived. The econometric demand model is estimated with per capita U.S. consumption of 21 foods on the time period 1919-1994, excluding the World War II years 1942-1946. An approach for inferring the percentage of nutrients available from individual commodities in the U.S. food supply is derived and implemented empirically on the time period 1949-1995 for the nutrients energy, protein, total fat, carbohydrates, and cholesterol. The two sets of model results are combined to generate time paths for income and Hicksian compensated price elasticities of demand for individual foods and macronutrients.
Universal Properties of a Run-and-Tumble Particle in Arbitrary Dimension

description: We consider an active run-and-tumble particle (RTP) in $d$ dimensions, starting from the origin and evolving over a time interval $[0,t]$. We examine three different models for the dynamics of the RTP: the standard RTP model with instantaneous tumblings, a variant with instantaneous runs and a general model in which both the tumblings and the runs are non-instantaneous. For each of these models, we use the Sparre Andersen theorem for discrete-time random walks to compute exactly the probability that the $x$ component does not change sign up to time $t$, showing that it does not depend on $d$. As a consequence of this result, we compute exactly other $x$-component properties, namely the distribution of the time of the maximum and the record statistics, showing that they are universal, i.e. they do not depend on $d$. Moreover, we show that these universal results hold also if the speed $v$ of the particle after each tumbling is random, drawn from a generic probability distribution. Our findings are confirmed by numerical simulations. Some of these results have been announced in a recent Letter [Phys. Rev. Lett. 124, 090603 (2020)].

description: Modern economic growth models show that the equilibrium outcome may depend on agents' beliefs (expectations) rather than on economic fundamentals (history). In this situation, the equilibrium is indeterminate. However, if agents have "almost common knowledge" rather than common knowledge about the economic fundamentals, this indeterminacy vanishes in one of these models, under certain restrictions. In this situation, the unique competitive equilibrium can be influenced by government policy, just as in standard models.

description: We study the diffusive behavior of biased Brownian particles in a two dimensional confined geometry filled with the freezing obstacles. The transport properties of these particles are investigated for various values of the obstacles density $η$ and the scaling parameter $f$, which is the ratio of work done to the particles to available thermal energy. We show that, when the thermal fluctuations dominate over the external force, i.e., small $f$ regime, particles get trapped in the given environment when the system percolates at the critical obstacles density $η_c \approx 1.2$. However, as $f$ increases, we observe that particles trapping occurs prior to $η_c$. In particular, we find a relation between $η$ and $f$ which provides an estimate of the minimum $η$ up to a critical scaling parameter $f_c$ beyond which the Fick-Jacobs description is invalid. Prominent transport features like nonmonotonic behavior of the nonlinear mobility, anomalous diffusion, and greatly enhanced effective diffusion coefficient are explained for various strengths of $f$ and $η$. Also, it is interesting to observe that particles exhibit different kinds of diffusive behaviors, i.e., subdiffusion, normal diffusion, and superdiffusion. These findings, which are genuine to the confined and random Lorentz gas environment, can be useful to understand the transport of small particles or molecules in systems such as molecular sieves and porous media which have a complex heterogeneous environment of the freezing obstacles.
