Geographic Difference-in-Discontinuities
Creators: name: Butts, Kyle
Publisher: name: arXiv
Year: 2021
Subjects: subject: Econometrics (econ.EM)
subject: FOS: Economics and business

description: A recent econometric literature has critiqued the use of regression discontinuities where administrative borders serves as the 'cutoff'. Identification in this context is difficult since multiple treatments can change at the cutoff and individuals can easily sort on either side of the border. This note extends the difference-in-discontinuities framework discussed in Grembi et. al. (2016) to a geographic setting. The paper formalizes the identifying assumptions in this context which will allow for the removal of time-invariant sorting and compound-treatments similar to the difference-in-differences methodology.

A minimal Little Higgs model
Creators: name: Barcelo, Roberto
name: Masip, Manuel
Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We discuss a Little Higgs scenario that introduces below the TeV scale just the two minimal ingredients of these models, a vectorlike T quark and a singlet component (implying anomalous couplings) in the Higgs field, together with a pseudoscalar singlet η. In the model, which is a variation of Schmaltz's simplest Little Higgs model, all the extra vector bosons are much heavier than the T quark. In the Yukawa sector the global symmetry is approximate, implying a single large coupling per flavour, whereas in the scalar sector it is only broken at the loop level. We obtain the one-loop effective potential and show that it provides acceptable masses for the Higgs h and for the singlet ηwith no need for an extra μterm. We find that m_ηcan be larger than m_h/2, which would forbid the (otherwise dominant) decay mode h -> ηη.

The illusion of influence : Soviet-Indian strategic relations in the 1970's
Creators: name: Robinson, Peter C.
Publisher: name: University of British Columbia
Year: 2010

description: This study is concerned with analyzing aspects of the influence relationship that has grown up between the U.S.S.R. and India since the late 1950's. Its chief concentration is upon the ability of the U.S.S.R. to exert constraining influence upon the direction of Indian foreign policy making in the present decade. In the past there has been a tendency for Western analysts to greatly overestimate the degree of Soviet influence on Third World countries. In large part, this has been a result of an undue concentration on the range of diplomatic tools available to the Soviet Union without sufficient attention being paid to the concrete returns from their usage. This study, utilizing a framework of enquiry in part suggested by Rubinstein in Red Star on the Nile, therefore, concentrates on an analysis of the effect of Soviet influence techniques on issues in the area of Indo-Soviet strategic interaction. The study proceeds through detailed analysis of a small number of the more significant contentious issues that have arisen in recent years between the two countries. It assumes that by tracing the development of these issues and the manner in which they were resolved (or otherwise), one can gain a very very real indication of the effectiveness of Soviet attempts at influence building. The substantive chapters of the study involve detailed analysis of Indo-Soviet interaction during the Bangladesh crisis of 1971, the Russian attempts to gain Indian endorsement of Brezhnev's plan for collective security in Asia, and recent trends in Indo-Soviet strategic relations, including analysis of India's military procurement policies and its diplomatic relations with Pakistan, China and the United States. This last case study is then supplemented by analysis of recent trends in Indo-Soviet economic cooperation. On the basis of the evidence provided by these case studies it is suggested that Soviet influence upon Indian foreign policy decision making in this decade has been, and will likely continue to be, very insubstantial.

title:  The Aesthetics of Suffering or Being Enchanted by Van Gogh’s Ear
Creators: name: Démuth, Andrej

Publisher: name: Roma TrE-Press
Year: 2021

description: The paper focuses on an analysis of the aesthetic appeal of suffering in the visual arts and literature with special regard to the problem of self-harm and its visual representation. The text is based on the assumption that suffering is part of our everyday life. However, the way it is expressed may lead to something that is not everyday – it is addressed to others – to try to change their perceptions and actions. On the contrary, self-torture or self-sacrifice is, in principle, considered to be uncommon, and their temporal domain is rather non-everydayness. This non-everydayness has attracted some attention from the days of Attis, through Christ, to the ear of van Gogh. Although self-harm and self-torture may and often have in principle a hidden and intimate character, they are nevertheless addressed to a certain audience that is supposed to see them and whom they affect. The paper considers selected reasons for the aesthetic appeal of (self-) suffering and focuses on the visual rhetoric of bodily self-harm as a means to make the inner world of the individual visible. It analyses some forms of self-harm, along with their aesthetic presentation in everyday life, as well as in an artistic environment. The authors thus aim to clarify the attractiveness of the suffering that is displayed as well as the various forms of the aesthetics of suffering and self-harm, which has both historical and modern forms.

description: Transport of angular momentum is one of the thrust areas of astrophysical flows. Instabilities and hence the turbulence generated by it has been invoked to understand its role in angular momentum transport in hydrodynamic and magnetohydrodynamic regime. Investigation of an unexplored region described by the parameter space $Ω_e^2 < 0$, $Ω_e$ being the epicyclic frequency, resulted in a powerful magnetohydrodynamic instability. The growth rate of this instability is rather large and is found to depend on the wavenumber.

description: Similar to interactions between dipoles, or van der Waals interactions, quadrupole-quadrupole interactions are interactions between quadrupoles. In this article, we study the quadrupole interactions between highly excited atoms or Rydberg atoms. In addition, unlike many other calculations, in which the primary focus was on the one-dimensional two-body quadrupole-quadrupole interactions, the primary aim of this article is to study the two-dimensional few-body quadrupole-quadrupole interactions. Specifically, the two-dimensional three-body interactions are investigated. This research has many applications, such as quadrupole-blockade for quantum computing, creating molecules based on quadrupole interactions.

description: Recently, the European Commission supported by many European countries has announced large investments towards the commercialization of quantum technology (QT) to address and mitigate some of the biggest challenges facing today's digital era - e.g. secure communication and computing power. For more than two decades the QT community has been working on the development of QTs, which promise landmark breakthroughs leading to commercialization in various areas. The ambitious goals of the QT community and expectations of EU authorities cannot be met solely by individual initiatives of single countries, and therefore, require a combined European effort of large and unprecedented dimensions comparable only to the Galileo or Copernicus programs. Strong international competition calls for a coordinated European effort towards the development of QT in and for space, including research and development of technology in the areas of communication and sensing. Here, we aim at summarizing the state of the art in the development of quantum technologies which have an impact in the field of space applications. Our goal is to outline a complete framework for the design, development, implementation, and exploitation of quantum technology in space.

Spontaneous emission of atomic systems in the presence of incident fields

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We characterise the spontaneous emission time and direction from small numbers of dipole-coupled two-level atoms (2LAs) in the presence of incident fields. We show how to use adiabatic passage to admit population transfer between states in the one-quantum subspace for two and three 2LAs. Our method is a multi-atom generalisation of stimulated-Raman-adiabatic-passage (STIRAP) for a single multi-level atom. We use numerical results to justify an ansatz that enables us to give analytical expressions for the directional emission which depends on the incident fields. Our results admit a characterisation of the efficacy of population transfer in small numbers of dipole-coupled 2LAs, and are applicable to proof-of-principle experiments involving dipole-coupled 2LAs.

Microscopics of disordered two-dimensional electron gases under high magnetic fields: Equilibrium properties and dissipation in the hydrodynamic regime

Publisher: name: arXiv

description: We develop in detail a new formalism [as a sequel to the work of T. Champel and S. Florens, Phys. Rev. B 75, 245326 (2007)] that is well-suited for treating quantum problems involving slowly-varying potentials at high magnetic fields in two-dimensional electron gases. For an arbitrary smooth potential we show that electronic Green's function is fully determined by closed recursive expressions that take the form of a high magnetic field expansion in powers of the magnetic length l_B. For illustration we determine entirely Green's function at order l_B^3, which is then used to obtain quantum expressions for the local charge and current electronic densities at equilibrium. Such results are valid at high but finite magnetic fields and for arbitrary temperatures, as they take into account Landau level mixing processes and wave function broadening. We also check the accuracy of our general functionals against the exact solution of a one-dimensional parabolic confining potential, demonstrating the controlled character of the theory to get equilibrium properties. Finally, we show that transport in high magnetic fields can be described hydrodynamically by a local equilibrium regime and that dissipation mechanisms and quantum tunneling processes are intrinsically included at the microscopic level in our high magnetic field theory. We calculate microscopic expressions for the local conductivity tensor, which possesses both transverse and longitudinal components, providing a microscopic basis for the understanding of dissipative features in quantum Hall systems.

A study of sensitivity gradients and spatial summation in the normal retina by static chromatic perimetry with photometrically-equated stimuli under fully-photopic and fully-scotopic conditions
Creators: name: Dunn, Patrice Mary
Publisher: name: University of British Columbia
Year: 2010

description: A study was conducted to investigate the sensitivity and spatial summation properties of the normal retina under fully-photopic and fully-scotopic conditions, using photometrically-equated chromatic stimuli of four sizes. Fully-photopic adaptation yielded equivalent sensitivity gradients extra-foveally but different foveal thresholds for the red, green and blue stimuli. The extra-foveal scotopic sensitivity gradients were similar in form but different in height for the chromatic stimuli, while all stimuli excepting the smaller red ones yielded "relative scotomata" at the fovea. Spatial summation was shown to increase with eccentricity and decrease with increasing stimulus size under fully-photopic but not under fully-scotopic conditions, but was found in general to be greater under scotopic adaptation.

description: Using previous results on the statistics of intersecting D6-brane models on T^6/Z_6' we analyse solutions that resemble the gauge group and matter content of the supersymmetric standard model. In particular the structure of the hidden sector, the gauge coupling constants and chiral exotic matter content are computed and classified for all possible standard model-like configurations on this background. It turns out that the number of chiral exotics, Higgses and values of gauge couplings are strongly correlated. Some examples with the chiral spectrum of the supersymmetric standard model plus vector-like states and a massless U(1) B-L are discussed in detail.

The formalism incorporates the Equivalence Principle. Newton-Hooke conformal symmetries, which are analogs of those of Schroedinger in the presence of a negative cosmological constant, are discussed in a similar way. Further examples include topologically massive gravity with negative cosmological constant and the Madelung hydrodynamical description.

Kurtosis and compressibility near the chiral phase transition

description: The properties of net quark number fluctuations in the vicinity of the QCD chiral phase transition are discussed in terms of an effective chiral model in the mean-field approximation. We focus on the ratio of the fourth- to second- order cumulants (kurtosis) and the compressibility of the system and discuss their dependence on the pion mass. It is shown that near the chiral phase transition, both observables are sensitive to the value of $m_π$. For physical $m_π$, the kurtosis exhibits a peak whereas the inverse compressibility shows a dip at the pseudocritical temperature. These structures disappear for large $m_π$. Our results, obtained in an effective model with two flavors, are qualitatively consistent with recent results of 2+1 flavor lattice gauge theory. We also discuss the high- and low-temperature properties of these observables and the role of the coupling of the quark degrees of freedom to the Polyakov loop.
A pen-tip pressure-based system for real-time handprinted character recognition
Creators: name: Willey, Stephen Raymond
Publisher: name: University of British Columbia
Year: 2010

description: An on-line handprinted character recognition scheme was developed, implemented, and tested. The selected symbol class included the numerics subset of the ANSI standard and nine special symbols defined for a proposed dedicated graphics editor system. A primary design objective was to provide an environment that would reflect the non-technical user's natural tendencies. A Xebec ball-point pen with a pressure-sensitive tip monitored drag forces generated in the plane of the paper. Force information was available to the processor by periodically sampling a strategically placed strain-gauge array. Data were analyzed in real-time to provide immediate inferences concerning stroke motion. Since positional information was not available no constraints were placed on the writing medium. The system is microprocessor compatible with total software comprising less than 1500 16-bit words. It is also very CPU efficient owing to a multi-level pre-processing scheme that significantly reduces the computing burden. Feature extraction is simple and effective. A hysteresis scheme is applied at all borders of the quantization plane to help eliminate redundant data. In the final stage input symbols are classified with the aid of a modified tree structure that is inherently tolerant to a large variety of local variations. The dictionary is compact and quickly traversed; provision for 19 symbols requires less than 250 words since only a fraction of all allowable forms need be explicitly specified. Extensive testing was conducted on the completed recognizer. A small amount of user training is required to ensure adequate performance. A total of more than 4000 characters obtained from 15 subjects were analyzed. Experienced users achieved a 96.3% average recognition rate and scores above 98% were not uncommon. Performance is independent of character size and position and users appear to retain skills acquired during training. Nontechnical and technical users perform equally well and are not distracted by the small amount of hardware involved. Efforts were directed to determine if the system could be dedicated to a particular user. In some cases, it was found that dictionary reconfiguration improved performance markedly. Optimal system parameter values were fairly robust, optimizing for a single subject yielded good results for all subjects. Exceptional writers, however, might benefit from some parameter fine-tuning. An automated personalization prototype designed to select optimal values was developed and tested.

Effectiveness of Mobile Wallet Promotions in Driving Customer Loyalty

Year: 2025

description: Due to the fast uptake of mobile wallets, they revolutionized the way we conduct online transactions, which forced many companies to implement their promotional offers like cashback, discounts, and rewards including loyalty programs for customer retention and engagement. This research aims a better understanding of the effectiveness of mobile wallet promotions in stimulating customer loyalty, the comparative influence of different promotional strategies, and the influence of trust and security concerns on user behaviour. Adopting quantitative research approach, survey data were collected from 100 mobile wallet users and analysed using regression, Chi-Square tests, and correlation analysis. However, the results revealed that promotions act as a positive driver of customer loyalty (R = 0.432, p = 0.000). Cashback was the most preferable incentive, but Chi-Square analysis (p = 0.057) did not find a statistically significant difference between cashback and discounts in lengthening long-term retention. Furthermore, security perception (i.e., how people view the security status of a place or offering) had no notable impact on promotional engagement (r = -0.024, p = 0.811), indicating that customers perceived security and promotional offers independently. These results highlight the need for a diverse promotional strategy which integrates: personalized incentive journeys, seamless transaction processes, and trust establishing devices. Such insights allow the mobile wallet providers to fine tune the marketing strategy so that they can maintain the user engagement even in this increasingly competitive digital payment ecosystem.

We also analyze the features of the baryonic matter in holographic QCD by investigating the system of single brane-induced Skyrmion on a three-dimensional closed manifold $S^3$. We propose a new interesting picture of ``pion dominance'' near the critical density.

 Material examined
Six specimens (adults and nymphs) (unfortunately, most specimens have fallen apart), small lake Nausori Highlands, Viti Levu, Fiji, 523 m a.s.l., 17º 48.596 S –177º 40.965 E, 23 October 2003.
 Description
Female: body approximately 2700 long, body colour red. Ocular plate 421 long. Capitulum 413 long. Genital field with two rows of 10 setae. Number of acetabula approximately 80. Lengths of PI–PV: 12, 62, 50, 68, 22. Lengths of I­leg­4­6: 116, 150, 140. Lengths of IV­leg­4­6: 266, 288, 246. For all other characters see Harvey (1990).
 Remarks
 Adults of Limnochares australica are virtually indistinguishable from the Indian and African specimens of L. crinita Koenike. However, Martin & Smit (2002) showed that the larvae of both species were quite different. Outside Australia, the species has been reported from New Zealand (Smit 1996) and New Caledonia (Smit 2002), so it is reported here for the first time from Fiji. All these specimens were tentatively assigned to L. australica, as larvae were unknown. The same applies to the specimens from Fiji, and therefore the assignment to L. australica must be considered as tentative. Leg segments from specimens from New Caledonia and Fiji are shorter than those given for Australian specimens by Harvey (1990), but there is a considerable variation in the morphology, both between and within populations.

description: An accurate modeling of neutrino flux attenuation and the distribution of leptons they produce in transit through the Earth is an essential component to determine neutrino flux sensitivities of underground, sub-orbital and space-based detectors. Through neutrino oscillations over cosmic distances, astrophysical neutrino sources are expected to produce nearly equal fluxes of electron, muon and tau neutrinos. Of particular interest are tau neutrinos that interact in the Earth at modest slant depths to produce $τ$-leptons. Some $τ$-leptons emerge from the Earth and decay in the atmosphere to produce extensive air showers. Future balloon-borne and satellite-based optical Cherenkov neutrino telescopes will be sensitive to upward air showers from tau neutrino induced $τ$-lepton decays. We present nuPyProp, a python code that is part of the nuSpaceSim package. nuPyProp generates look-up tables for exit probabilities and energy distributions for $ν_τ\to τ$ and $ν_μ\to μ$ propagation in the Earth. This flexible code runs with either stochastic or continuous electromagnetic energy losses for the lepton transit through the Earth. Current neutrino cross section models and energy loss models are included along with templates for user input of other models. Results from nuPyProp are compared with other recent simulation packages for neutrino and charged lepton propagation. Sources of modeling uncertainties are described and quantified.

These manifolds are generalizations or topological counterparts of nonsingular projective toric varieties. In this article we study structures and invariants of quasitoric orbifolds. In particular, we discuss equivalent definitions and determine the orbifold fundamental group, rational homology groups and cohomology ring of a quasitoric orbifold. We determine whether any quasitoric orbifold can be the quotient of a smooth manifold by a finite group action or not. We prove existence of stable almost complex structure and describe the Chen-Ruan cohomology groups of an almost complex quasitoric orbifold.

description: Spectroscopic and photometric properties of low and high-z supernovae Ia (SNe Ia) have been analyzed in order to achieve a better understanding of their diversity and to identify possible SN Ia sub-types. We use wavelet transformed spectra in which one can easily measure spectral features. We investigate the \ion{Si}{II} 4000 equivalent width ($EW_w\lbrace\ion{Si}{II}\rbrace$). The ability and, especially, the ease in extending the method to SNe at high-$z$ is demonstrated. We applied the method to 110 SNe Ia and found correlations between $EW_w\lbrace\ion{Si}{II}\rbrace$ and parameters related to the light-curve shape for 88 supernovae with available photometry. No evidence for evolution of $EW_w\lbrace\ion{Si}{II}\rbrace$ with redshift is seen. Three sub-classes of SNe Ia were confirmed using an independent cluster analysis with only light-curve shape, colour, and $EW_w\lbrace\ion{Si}{II}\rbrace$. SNe from high-$z$ samples seem to follow a similar grouping to nearby objects. The $EW_w\lbrace\ion{Si}{II}\rbrace$ value measured on a single spectrum may point towards SN Ia sub-classification, avoiding the need for expansion velocity gradient calculations.

description: Sorting is an essential operation which is widely used and is fundamental to some very basic day to day utilities like searches, databases, social networks and much more. Optimizing this basic operation in terms of complexity as well as efficiency is cardinal. Optimization is achieved with respect to space and time complexities of the algorithm. In this paper, a novel left-field N-dimensional cartesian spaced sorting method is proposed by combining the best characteristics of bucket sort, counting sort and radix sort, in addition to employing hashing and dynamic programming for making the method more efficient. Comparison between the proposed sorting method and various existing sorting methods like bubble sort, insertion sort, selection sort, merge sort, heap sort, counting sort, bucket sort, etc., has also been performed. The time complexity of the proposed model is estimated to be linear i.e. O(n) for the best, average and worst cases, which is better than every sorting algorithm introduced till date.

description: Transverse entanglement between pairs of photons can be detected through intensity correlation measurements in the near and far fields. We show theoretically and experimentally that at intermediate zones, it is also possible to detect transverse entanglement performing only intensity correlation measurements.

description: Substructures, expected in cold dark matter haloes, have been proposed to explain the anomalous flux ratios in gravitational lenses. About 25% of lenses in the Cosmic Lens All-Sky Survey (CLASS) appear to have luminous satellites within ~ 5 kpc/h of the main lensing galaxies, which are usually at redshift z ~ 0.2-1. In this work we use the Millennium Simulation combined with galaxy catalogues from semi-analytical techniques to study the predicted frequency of such satellites in simulated haloes. The fraction of haloes that host bright satellites within the (projected) central regions is similar for red and blue hosts and is found to increase as a function of host halo mass and redshift. Specifically, at z = 1, about 11% of galaxy-sized haloes (with masses between 10^{12} M_sun/h and 10^{13} M_sun/h) host bright satellite galaxies within a projected radius of 5 kpc/h. This fraction increases to about 17% (25%) if we consider bright (all) satellites of only group-sized haloes (with masses between 10^{13} M_sun/h and 10^{14} M_sun/h). These results are roughly consistent with the fraction (~ 25%) of CLASS lensing galaxies observed to host luminous satellites. At z = 0, only ~ 3% of galaxy-sized haloes host bright satellite galaxies. The fraction rises to ~ 6%, (10%) if we consider bright (all) satellites of only group-sized haloes at z = 0. However, most of the satellites found in the inner regions are `orphan' galaxies where the dark matter haloes have been completely stripped. Thus the agreement crucially depends on the true survival rate of these `orphan' galaxies. We also discuss the effects of numerical resolution and cosmologies on our results.

description: In this paper, we introduce a reversible version of a genetically modified mode jumping Markov chain Monte Carlo algorithm (GMJMCMC) for inference on posterior model probabilities in complex model spaces, where the number of explanatory variables is prohibitively large for classical Markov Chain Monte Carlo methods. Unlike the earlier proposed GMJMCMC algorithm, the introduced algorithm is a proper MCMC and its limiting distribution corresponds to the posterior marginal model probabilities in the explored model space under reasonable regularity conditions.

description: Continuous measurements of health outcome data are often dichotomized into binary ( i.e. positive/negative) data for diagnosis and subsequent statistical analysis. The disadvantages of dichotomizing continuous data for statistical inference are well established in the literature, yet this practice is commonplace in health research. In this thesis, we investigate the impact of dichotomization of data when the aim of analysis is to determine disease prevalence and risk, and propose solutions to some of the main challenges introduced by dichotomization in the context of global heath research. First, using model-based geostatistics, we show how dichotomization reduces the predictive performance of geostatistical models through loss of information and by reducing the reliability of parameter estimates. We demonstrate this using a simulation study, as well as mapping prevalence and risk of anaemia in Ethiopia, and stunting in Ghana. We then explore the limitations dichotomization introduces to estimation of malaria transmission in serology models, and propose a novel flexible and unified modelling framework which uses continuous antibody measurements instead of dichotomized data to estimate transmission intensity. Using Western Kenya, we demonstrate the properties of this new approach. Finally, we address the use of thresholds for dichotomization of continuous antibody measurements when the goal is to estimate malaria seroprevalence. We utilize the principles of the unified modelling framework to develop a threshold-free approach to estimating seroprevalence. Using the same Western Kenyan data-set, we show how this new approach improves model fit and provides more consistent estimates than traditional methods. Together, these investigations demonstrate the significant impact dichotomization of continuous data has on statistical inference across different areas of health research, and that this practice should be avoided where possible.

description: Coronavirus is a large virus family consisting of diverse viruses, some of which disseminate among mammals and others cause sickness among humans. COVID-19 is highly contagious and is rapidly spreading, rendering its early diagnosis of preeminent status. Researchers, medical specialists and organizations all over the globe have been working tirelessly to combat this virus and help in its containment. In this paper, a novel neural network called WisdomNet has been proposed, for the diagnosis of COVID-19 using chest X-rays. The WisdomNet uses the concept of Wisdom of Crowds as its founding idea. It is a two-layered convolutional Neural Network (CNN), which takes chest x-ray images as input. Both layers of the proposed neural network consist of a number of neural networks each. The dataset used for this study consists of chest x-ray images of COVID-19 positive patients, compiled and shared by Dr. Cohen on GitHub, and the chest x-ray images of healthy lungs and lungs affected by viral and bacterial pneumonia were obtained from Kaggle. The network not only pinpoints the presence of COVID-19, but also gives the probability of the disease maturing into Acute Respiratory Distress Syndrome (ARDS). Thus, predicting the progression of the disease in the COVID-19 positive patients. The network also slender the occurrences of false negative cases by employing a high threshold value, thus aids in curbing the spread of the disease and gives an accuracy of 100% for successfully predicting COVID-19 among the chest x-rays of patients affected with COVID-19, bacterial and viral pneumonia.

description: Observations from the Hinode/XRT telescope and STEREO/SECCHI/EUVI are utilized to study polar coronal jets and plumes. The study focuses on the temporal evolution of both structures and their relationship. The data sample, spanning April 7-8 2007, shows that over 90% of the 28 observed jet events are associated with polar plumes. EUV images (STEREO/SECCHI) show plume haze rising from the location of approximately 70% of the polar X-ray (Hinode/XRT) and EUV jets, with the plume haze appearing minutes to hours after the jet was observed. The remaining jets occurred in areas where plume material previously existed causing a brightness enhancement of the latter after the jet event. Short-lived, jet-like events and small transient bright points are seen (one at a time) at different locations within the base of pre-existing long-lived plumes. X-ray images also show instances (at least two events) of collimated-thin jets rapidly evolving into significantly wider plume-like structures that are followed by the delayed appearance of plume haze in the EUV. These observations provide evidence that X-ray jets are precursors of polar plumes, and in some cases cause brightenings of plumes. Possible mechanisms to explain the observed jet and plume relationship are discussed.

description: We derive CP-violating transport equations for fermions for electroweak baryogenesis from the CTP-formalism including thermal corrections at the one-loop level. We consider both the VEV-insertion approximation (VIA) and the semiclassical (SC) formalism. We show that the VIA-method is based on an {\em assumption} that leads to an ill-defined source term containing a pinch singularity, whose regularisation by thermal effects leads to ambiguities including spurious ultraviolet and infrared divergences. We then carefully review the derivation of the semiclassical formalism and extend it to include thermal corrections. We present the semiclassical Boltzmann equations for thermal WKB-quasiparticles with source terms up to the second order in gradients that contain both dispersive and finite width corrections. We also show that the SC-method reproduces the current divergence equations and that a correct implementation of the Fick's law captures the semiclassical source term even with conserved total current $\partial_μj^μ= 0$. Our results show that the VIA-source term is not just ambiguous, but that it does not exist. Finally, we show that the collisional source terms reported earlier in the semiclassical literature are also spurious, and vanishes in a consistent calculation.
