description: Phase transitions have recently been formulated in the time domain of quantum many-body systems, a phenomenon dubbed dynamical quantum phase transitions (DQPTs), whose phenomenology is often divided in two types. One refers to distinct phases according to long-time averaged order parameters, while the other is focused on the non-analytical behavior emerging in the rate function of the Loschmidt echo. Here we show that such DQPTs can be found in systems with few degrees of freedom, i.e. they can take place without resorting to the traditional thermodynamic limit. We illustrate this by showing the existence of the two types of DQPTs in a quantum Rabi model -- a system involving a spin-$\frac{1}{2}$ and a bosonic mode. The dynamical criticality appears in the limit of an infinitely large ratio of the spin frequency with respect to the bosonic one. We determine its dynamical phase diagram and study the long-time averaged order parameters, whose semiclassical approximation yields a jump at the transition point. We find the critical times at which the rate function becomes non-analytical, showing its associated critical exponent as well as the corrections introduced by a finite frequency ratio. Our results open the door for the study of DQPTs without the need to scale up the number of components, thus allowing for their investigation in well controllable systems.

description: The papers aims to present the results of the analysis of total value of expenditure on innovation activities in the field of product and process innovations related to the acquisition of knowledge in the food industry enterprises in Poland in the years 2008-2011. They indicates that there was a global decline in these expenditures by over 28%. The decrease in these expenditures was recorded in the companies producing food and tobacco products. The increase in these expenditures was recorded in enterprises producing beverages. The study suggests that the food industry largely acquires knowledge in the framework of direct trade relations, as well as from external companies. For most of the surveyed enterprises of food industry knowledge management in the years 2007-2011 improved their economic performance or operating conditions thus contributing to their development and competitiveness.
Conformal Field Theory at central charge c=0 and Two-Dimensional Critical Systems with Quenched Disorder

description: We examine two-dimensional conformal field theories (CFTs) at central charge c=0. These arise typically in the description of critical systems with quenched disorder, but also in other contexts including dilute self-avoiding polymers and percolation. We show that such CFTs must in general possess, in addition to their stress energy tensor T(z), an extra field whose holomorphic part, t(z), has conformal weight two. The singular part of the Operator Product Expansion (OPE) between T(z) and t(z) is uniquely fixed up to a single number b, defining a new `anomaly' which is a characteristic of any c=0 CFT, and which may be used to distinguish between different such CFTs. The extra field t(z) is not primary (unless b=0), and is a so-called `logarithmic operator' except in special cases which include affine (Kac-Moody) Lie-super current algebras. The number b controls the question of whether Virasoro null-vectors arising at certain conformal weights contained in the c=0 Kac table may be set to zero or not, in these nonunitary theories. This has, in the familiar manner, implications on the existence of differential equations satisfied by conformal blocks involving primary operators with Kac-table dimensions. It is shown that c=0 theories where t(z) is logarithmic, contain, besides T and t, additional fields with conformal weight two. If the latter are a fermionic pair, the OPEs between the holomorphic parts of all these conformal weight-two operators are automatically covariant under a global U(1|1) supersymmetry. A full extension of the Virasoro algebra by the Laurent modes of these extra conformal weight-two fields, including t(z), remains an interesting question for future work.

title: Optimising the Loading Diversity of Rail Passenger Crowding using On-Board Occupancy Data
Creators: name: Ball, Simon David
Publisher: name: The Open University
Year: 2016

description: Crowded conditions on trains can lead to lower passenger satisfaction, discourage rail travel, result in negative economic impacts and are a factor in a number of health and safety hazards. In the UK there is an annual survey of rail passenger crowding, although the measures used do not reflect coach-by-coach variations, nor do they reflect variations across the peak period. In this MPhil thesis I investigated the application of weight-based automatic passenger counting data to deliver more even loadings on trains through the provision of new real-time and static solutions. In addition I investigated the potential benefits of such solutions in terms of reduced dwell times and reduced crowding. The overall concept proposed was to make the most of the existing available capacity; for example, so that no-one is standing when seats are available. Through analysing a large sample of air suspension data, I identified station-specific trends where some coaches were over capacity while others had spare capacity. I also conducted a critical review of academic research into on-train crowding and solutions that seek to optimise ‘loading diversity’. This study contributes to this emerging subject area in several ways: I propose two new metrics to describe inter-coach loading diversity that, unlike existing metrics, contain information relative to the capacity; I have revealed a link between the inter-coach loading diversity metrics and estimated boarding times, with trains classified as ‘very uneven’ on departure typically having dwell times of approximately five to ten seconds greater than services that were classified as being ‘even’ with a similar total number of passengers on board; and finally I have applied classification supervised learning techniques to predict the load factor for a given service and these predictors were an improvement over taking the historical average.

description: The pathogenicity of avian pathogenic Escherichia coli (APEC) can be reliably determined using a biological model with 1-day-old chicks. However, public concerns regarding the use of vertebrates in research have led to the exploration of other biological models. Alternative infection models, including Galleria mellonella larvae, have also been studied. This study aimed to evaluate whether G. mellonella larvae are a viable in vivo model for evaluating the pathogenicity of APEC isolates and to determine the best protocol for this model. First, the pathogenicity index (PI) in vivo was determined for 40 APEC isolates from 1-day-old chicks. The same isolates were then used to establish the best protocol for the determination of PI in larvae of G. mellonella by determining the LD50, melanization, cytotoxicity test, total haemocyte count, mortality rate, construction of survival curves, and larval disease score. Cytotoxicity tests and total haemocyte counts were not suitable for distinguishing the pathogenicity groups. LD50 was a useful tool for differentiating between high and low pathogenicity but not for intermediate pathogenicity. Similarly, melanization could be used as a variable to characterize the pathogenicity of APEC isolates but should be associated with other variables. Mortality rates and survival curves were useful tools for characterizing nonpathogenic and highly pathogenic isolates. In this study, G. mellonella larvae were a viable model, and the larval disease score was the main variable that determined the pathogenicity of APEC isolates in the G. mellonella model. Galleria mellonella larvae are a viable model for determining APEC pathogenicity.Larval disease score is the main variable for determining APEC pathogenicity.Response variables should be evaluated up to 24 h post-inoculation. Galleria mellonella larvae are a viable model for determining APEC pathogenicity. Larval disease score is the main variable for determining APEC pathogenicity.

description: Manual visual inspection performed by certified inspectors is still the main form of road pothole detection. This process is, however, not only tedious, time-consuming and costly, but also dangerous for the inspectors. Furthermore, the road pothole detection results are always subjective, because they depend entirely on the individual experience. Our recently introduced disparity (or inverse depth) transformation algorithm allows better discrimination between damaged and undamaged road areas, and it can be easily deployed to any semantic segmentation network for better road pothole detection results. To boost the performance, we propose a novel attention aggregation (AA) framework, which takes the advantages of different types of attention modules. In addition, we develop an effective training set augmentation technique based on adversarial domain adaptation, where the synthetic road RGB images and transformed road disparity (or inverse depth) images are generated to enhance the training of semantic segmentation networks. The experimental results demonstrate that, firstly, the transformed disparity (or inverse depth) images become more informative; secondly, AA-UNet and AA-RTFNet, our best performing implementations, respectively outperform all other state-of-the-art single-modal and data-fusion networks for road pothole detection; and finally, the training set augmentation technique based on adversarial domain adaptation not only improves the accuracy of the state-of-the-art semantic segmentation networks, but also accelerates their convergence.

description: The aim of this paper was to assess the joint productivity of groups of agricultural holdings specializing in field cultivation, taking into account modifications being the result of optimisation analysis and the DEA method. The results achieved by agricultural holdings operating in the Pomerania and Masuria region in the years 2004-2008 were researched based on data collected by Polish FADN (Farm Accountancy Data Network). Productivity function was measured using the three-factor Cobbs-Douglas production function, whereas changes in productivity were analysed using mathematical optimisation models, that is Lagrange’s method of undetermined multipliers, linear programming method and DEA non-parameter method. The results were compared with respect to farms’ productivity. The analysis indicates that the highest increase in productivity was achieved after implementation of changes suggested by Lagrange’s method of undetermined multipliers.

The obtained hyperfine constants, A_\parallel = -3826 MHz for the a(1) state and A_\parallel = 4887 MHz for the B(1) state, are in very good agreement with the experimental data, -4113 MHz and 5000 \pm 200 MHz, respectively. We find W_d = -(6.1 ^{+1.8}_{-0.6}) 10^{24} Hz/(e cm) for a(1), and W_d = (8.0 \pm 1.6) 10^{24} Hz/(e cm) for B(1). The obtained values are analyzed and compared to recent relativistic coupled cluster results and a semiempirical estimate of W_d for the a(1) state.

description: This article discusses some trends and concepts in developing new generation of future Artificial General Intelligence (AGI) systems which relate to complex facets and different types of human intelligence, especially social, emotional, attentional and ethical intelligence. We describe various aspects of multiple human intelligences and learning styles, which may impact on a variety of AI problem domains. Using the concept of 'multiple intelligences' rather than a single type of intelligence, we categorize and provide working definitions of various AGI depending on their cognitive skills or capacities. Future AI systems will be able not only to communicate with human users and each other, but also to efficiently exchange knowledge and wisdom with abilities of cooperation, collaboration and even co-creating something new and valuable and have meta-learning capacities. Multi-agent systems such as these can be used to solve problems that would be difficult to solve by any individual intelligent agent. Key words: Artificial General Intelligence (AGI), multiple intelligences, learning styles, physical intelligence, emotional intelligence, social intelligence, attentional intelligence, moral-ethical intelligence, responsible decision making, creative-innovative intelligence, cognitive functions, meta-learning of AI systems.

Whitewatching : cinema, race and regulation in the progressive-era United States
Creators: name: Olund, Eric Nicholas
Publisher: name: University of British Columbia
Year: 2010

description: Cinema emerged during a period of enormous social change in the United States. Gender relations were changing as the "New Woman" asserted her place in public life on more individualistic grounds, and ethnic relations were changing as vast numbers of Catholic and Jewish "New Immigrants" were changing the face of the growing industrial cities of the Northeast and Midwest. Urban reformers, many of whom were themselves New Women as well as professionals characteristic of the corporate capitalism emerging at the time, saw cinema as an opportunity to assimilate immigrants to the self-governing ideals of white, middle-class American subjectivity. They formed the unofficial National Board of Review of Motion Pictures in New York City to review films prior to distribution in voluntary cooperation with the manufacturers. While Progressive era reformers often advocated increasing state intervention in other spheres of activity, they sought to pursue what they termed a constructive agenda for cinema in order to develop its educational and artistic potential and limit the police power of the state to regulating exhibition conditions and prosecuting obscenity. This experiment in governmentality had a racialized geography that went well beyond either the New Immigrants or New York, however. African Americans were moving in large numbers to these same cities from the South, yet these reformers remained willfully ignorant of their new neighbors. Drawing on archival case studies of Atlanta, Minneapolis and New York, with their very different racial, class and sexual politics, this project explores the variable geography of Progressive era cinema regulation and its production of whiteness.
Robust Learning from Discriminative Feature Feedback

description: Recent work introduced the model of learning from discriminative feature feedback, in which a human annotator not only provides labels of instances, but also identifies discriminative features that highlight important differences between pairs of instances. It was shown that such feedback can be conducive to learning, and makes it possible to efficiently learn some concept classes that would otherwise be intractable. However, these results all relied upon perfect annotator feedback. In this paper, we introduce a more realistic, robust version of the framework, in which the annotator is allowed to make mistakes. We show how such errors can be handled algorithmically, in both an adversarial and a stochastic setting. In particular, we derive regret bounds in both settings that, as in the case of a perfect annotator, are independent of the number of features. We show that this result cannot be obtained by a naive reduction from the robust setting to the non-robust setting.

description: We construct a nonperturbative regularization for Euclidean noncommutative supersymmetric Yang-Mills theories with four (N= (2,2)), eight (N= (4,4)) and sixteen (N= (8,8)) supercharges in two dimensions. The construction relies on orbifolds with discrete torsion, which allows noncommuting space dimensions to be generated dynamically from zero dimensional matrix model in the deconstruction limit. We also nonperturbatively prove that the twisted topological sectors of ordinary supersymmetric Yang-Mills theory are equivalent to a noncommutative field theory on the topologically trivial sector with reduced rank and quantized noncommutativity parameter. The key point of the proof is to reinterpret 't Hooft's twisted boundary condition as an orbifold with discrete torsion by lifting the lattice theory to a zero dimensional matrix theory.

The research was conducted within the area of 10 mountain communes within the region of the Carpathian Mountains in the territory of Poland and Ukraine. Multi-criteria method AHP was used for the purpose of the analysis and the author focused on the population’s mobility in three main areas: economic, environmental and agricultural, and social. The importance of migration processes were stressed in the transformations of the functioning of the affected mountain areas. Balancing adverse social effects with the economic activation of households in those areas may become a factor that helps reduce depopulation in the mountain areas and create an opportunity for the development of Carpathian villages as part of a multi-functional model.

All-optical versus electro-optical quantum-limited feedback

description: All-optical feedback can be effected by putting the output of a source cavity through a Faraday isolator and into a second cavity which is coupled to the source cavity by a nonlinear crystal. If the driven cavity is heavily damped, then it can be adiabatically eliminated and a master equation or quantum Langevin equation derived for the first cavity alone. This is done for an input bath in an arbitrary state, and for an arbitrary nonlinear coupling. If the intercavity coupling involves only the intensity (or one quadrature) of the driven cavity, then the effect on the source cavity is identical to that which can be obtained from electro-optical feedback using direct (or homodyne) detection. If the coupling involves both quadratures, this equivalence no longer holds, and a coupling linear in the source amplitude can produce a nonclassical state in the source cavity. The analogous electro-optic scheme using heterodyne detection introduces extra noise which prevents the production of nonclassical light. Unlike the electro-optic case, the all-optical feedback loop has an output beam (reflected from the second cavity). We show that this may be squeezed, even if the source cavity remains in a classical state.
description: 21 pages. This is an old (1994) paper, but one which I thought was worth posting because in addition to what is described in abstract it has: (1) the first formulation (to my knowledge) of quantum trajectories for an arbitrary (i.e. squeezed, thermal etc.) broadband bath; (2) the prediction of a periodic modification to the detuning and damping of an oscillator for the simplest sort of all-optical feedback (i.e. a mirror) as seen in the recent experiment "Forces between a Single Atom and Its Distant Mirror Image", P. Bushev et al, Phys. Rev. Lett. 92, 223602 (2004)

21 cm Tomography of the High-Redshift Universe with the Square Kilometer Array

description: We discuss the prospects for ``tomography'' of the intergalactic medium (IGM) at high redshifts using the 21 cm transition of neutral hydrogen. Existing observational constraints on the epoch of reionization imply a complex ionization history that may require multiple generations of sources. The 21 cm transition provides a unique tool to probe this era in detail, because it does not suffer from saturation effects, retains full redshift information, and directly probes the IGM gas. Observations in the redshifted 21cm line will allow one to study the history and morphology of reionization in detail. Depending on the characteristics of the first sources, they may also allow us to probe the era before reionization, when the first structures and luminous sources were forming. The construction of high signal-to-noise ratio maps on arcminute scales will require approximately one square kilometer of collecting area.

description: We revisit the consistency of torus partition functions in (1+1)$d$ fermionic conformal field theories, combining traditional ingredients of modular invariance/covariance with a modernized understanding of bosonization/fermionization dualities. Various lessons can be learned by simply examining the oft-ignored Ramond sector. For several extremal/kinky modular functions in the bootstrap literature, we can either rule out or identify the underlying theory. We also revisit the ${\cal N} = 1$ Maloney-Witten partition function by calculating the spectrum in the Ramond sector, and further extending it to include the modular sum of seed Ramond characters. Finally, we perform the full ${\cal N} = 1$ RNS modular bootstrap and obtain new universal results on the existence of relevant deformations preserving different amounts of supersymmetry.

Equilibrium Multiplicity in Aiyagari and Krusell-Smith

description: Repeatedly solving the Aiyagari (1994) model with random parameters, we construct hundreds of examples with multiple stationary equilibria. We never find multiplicity with risk aversion less than ≈ 1.49, depreciation less than ≈ 0.19, or income persistence less than ≈ 0.47, and multiplicity requires a disaster state for income. In cases with multiplicity, the lowest rental rate occurs near depreciation times the capital share. It is possible for the economy, without a change in fundamentals, to transition rationally from a higher-rate equilibrium to one with a lower rental rate, lower inequality, and lower welfare (for most agents). We also construct the first Krusell and Smith (1998) examples with multiple recursive competitive equilibria.

description: When GM crops were first commercialized, science-based risk assessments and regulations were applied to ensure food (human and animal) and environmental safety. Early adopting countries were Argentina, Canada, China, Europe and the United States. Over the intervening 20 years, commercial production spread to an additional 25 countries. With 20 years of adoption history, it is possible to assess if the diffusion of regulations away from a primarily science-based approach has impacted not only the adoption of GM crops, but also the diffusion of specific GM traits. By assessing GM crop adoption patterns it is possible to gain insights into the relationship between regulatory systems and adoption. To do this an analysis of adoption patterns has been utilized. The objective of the analysis is to look for differences and trends in GM crop adoption across traits, countries and years of diffusion. Timelines of adoption are used to show the correlation between regulatory systems and adoption. This analysis provides insights into whether market saturation points are shortening or lengthening, whether familiarity with traits is reducing regulatory timelines and whether the diffusion curve plateaus or trails off over time. Determining the impact regulations have on GM crop adoption provides both regulators and industry development firms with valuable information on the efficiency of GM crop regulations over time.
Quantitative test of a quantum theory for the resistive transition in a superconducting single-walled carbon nanotube bundle

description: The phenomenon of superconductivity depends on the coherence of the phase of the superconducting order parameter. The resistive transition in quasi-one-dimensional (quasi-1D) superconductors is broad because of a large phase fluctuation. We show that the resistive transition of a superconducting single-walled carbon nanotube bundle is in quantitative agreement with the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory. We also demonstrate that the resistive transition below T^*_c = 0.89T_c0 is simply proportional to exp [-(3βT^*_c/T)(1-T/T^*_c)^3/2], where the barrier height has the same form as that predicted by the LAMH theory and T_c0 is the mean field superconducting transition temperature.

description: Beyond the Standard Model scenarios with extensions of the Higgs sector typically predict new resonances that can undergo a series of cascade decays to detectable Standard Model particles. On one hand, sensitivity to such signatures will contribute to the full reconstruction of the extended Higgs potential if a new physics discovery will be made. On the other hand, such cascade decays could be dominant decay channels, thus being potentially the best motivated signatures to achieve a new physics discovery in the first place. In this work, we show how the long short-term memory that is encoded in the cascade decays' phenomenology can be exploited in discriminating the signal from the background, where no such information is present. In parallel, we demonstrate for theoretically motivated scenarios that such an approach provides improved sensitivity compared to more standard analyses, where only information about the signal's final state kinematics is included.

description: The long-term trend and its spatio-temporal characteristics of dew formation over the Beijing-Tianjin-Hebei (BTH) region are still poorly understood. We examined dew and its climatic controls in BTH from 2008 to 2021 over China with the aid of model estimation based on the atmospheric data from the China Meteorological Administration Land Data Assimilation System (CLDAS). Besides, the relevance of dew to drought was also examined. Dew amount showed a decreasing tendency from northwest to southeast over BTH for the 14 years. The average monthly accumulative dew amount ranged from 0.56 mm to 15.87 mm. The annual dew amount was highest in Bashang and lowest in Plain area. Precipitation(P), air temperature (Ta) and relative humidity (RH) all showed positive correlation with dew over the three ecoregions, and among these, RH showed the most significant correlation with dew. The BTH showed a drier trend over the study period and dew exhibited higher over the dry area. Our study can not only provide a novel understanding of dew characteristics in the BTH, but also have an important potential effect on the water resources management in the context of climate change exacerbation.

description: We present the results of a radio variability study of the gravitational lens PMN J1838-3427. Our motivation was to determine the Hubble constant by measuring the time delay between variations of the two quasar images. We monitored the system for 4 months (approximately 5 times longer than the expected delay) using the Australia Telescope Compact Array at 9 GHz. Although both images were variable on a time scale of a few days, no correlated intrinsic variability could be identified, and therefore no time delay could be measured. Notably, the fractional variation of the fainter image (8%) was greater than that of the brighter image (4%), whereas lensed images of a point source would have the same fractional variation. This effect can be explained, at least in part, as the refractive scintillation of both images due to the turbulent interstellar medium of the Galaxy.
