A Study on English-speaking Learners' Acquisition of Three Chinese Modal Auxiliary Verbs: NENG, HUI ,And KEYI
Creators: name: Li, Anqi
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: This study aims to investigate the acquisition of three Chinese modal auxiliary verbs: NENG, HUI, and KEYI by English-speaking learners who study Chinese as a foreign language and attempts to examine the following issues. 1) Are English-speaking learners able to distinguish the semantic difference between NENG, HUI and KEYI and realize their corresponding syntactic constraints? Does leaner’s acquisition of these three auxiliary verbs increase with the improvement of their Chinese proficiency level? Can these three auxiliary verbs be mastered completely by English-speaking leaners? 2) What is the acquisition order when they are learning NENG, HUI and KEYI? Furthermore, what is the acquisition order of the multiple semantic meanings within one single Chinese modal auxiliary verb? 3)What is the relationship between English-speaking learners’ comprehension and production, in regard to their performance on learning these three auxiliary verbs? 4) whatpedagogical implication does this study reveal?
This research is composed of a comprehension test and production analysis. A questionnaire is designed to test English-speaking learners’ comprehension of NENG, HUI and KEYI, including fourteenmultiple choices questions. In addition, 275 essays from the participants are collected anonymously as production database to be analyzed.
In total, 90 English-speaking learners who enrolled in Chinese courses at University of Massachusetts Amherst in Spring 2019 were participated, and they were divided into three experimental groups: beginning level, intermediate level, and advanced level. 60 native Chinese speakers were also invited into this research, served as a control group.
The result in this research shows that 1) English-speaking leaners’ acquisition of NENG, HUI and KEYI do not always increase with the improvement of their Chinese proficiency level. Both HUI and KEYI present the same trend, which rises rapidly and significantly after experiencing a relatively flat stage, while the development of NENG is shown by U-shape learning curve. 2) For English-speaking learners, the acquisition order is(from the easiest to hardest): HUI > KEYI > NENG. 3) English-speaking learners’ production of NENG, HUI, and KEYI is not always parallel to their comprehension. Also, some implications for teaching NENG, HUI and KEYI are discussed in this thesis.

description: At small x, the effects of finite transverse momenta of partons inside a hadron become increasingly important, especially in analyses of jets and heavy-quark production. These effects can be systematically accounted for in a formalism based on kT-factorization and unintegrated distribution functions. We present results for the unintegrated distribution function, together with the corresponding integrated one, obtained within the framework of the Linked Dipole Chain model. Comparisons are made to results obtained within other approaches.
The Promise of VR Headsets: Validation of a Virtual Reality Headset-Based Driving Simulator for Measuring Drivers’ Hazard Anticipation Performance
Creators: name: Pai Mangalore, Ganesh
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: The objective of the current study is to evaluate the use of virtual reality (VR) headsets to measure driving performance. This is desirable because they are several orders of magnitude less expensive and, if validated, could greatly extend the powers of simulation. Out of several possible measures of performance that could be considered for evaluating VR headsets, the current study specifically examines drivers’ latent hazard anticipation behavior both because it has been linked to crashes and because it has been shown to be significantly poorer in young drivers compared to their experienced counterparts in traditional driving simulators and in open road studies. The total time middle-aged drivers spend glancing at a latent hazard and the average duration of each glance was also compared to these same times for younger drivers using a VR headset and fixed-based driving simulator. In a between-subject design, forty-eight participants were equally and randomly assigned to one out of four experimental conditions – two young driver cohorts (18 – 21 years) and two middle-aged driver cohorts (30 – 55 years) navigating either a fixed-based driving simulator or a VR-headset-based simulator. All participants navigated six unique scenarios while their eyes were continually tracked. The proportion of latent hazards anticipated by participants which constituted the primary dependent measure was found to be greater for middle-aged drivers than young drivers across both platforms. Results also indicate that the middle-aged participants glanced longer than their younger counterparts on both platforms at latent hazards, as measured by the total glance duration but had no difference when measured by the average glance duration. Moreover, the difference in the magnitude of performance between middle-aged and younger drivers was the same across the two platforms. There were also no significant differences found for the severity of simulator sickness symptoms across the two platforms. The study provides some justification for the use of virtual reality headsets as a way of understanding drivers’ hazard anticipation behavior.

description: This paper presents development of a model for arrangement of indirect costs in wine production with an aim to gain better information for decision making. Wine producing companies face with constantly growing share of indirect costs in comparison to all other costs. Consequently the importance of their redeployment is becoming even more important in order to gain better cost information about each particular product. The model has been developed on basis of existing business process which gives the model a key differentiation in comparison to the existing ways of cost allocation. Moreover, such an approach includes all key business factors that should be considered in wine industry and is therefore directly applicable to »Goriška Brda« Wine Cellar. By taking into account additional wine-trade related factors/variables the model could also be used for indirect cost-allocation in other wine-trading related businesses.
Modeling Dynamic Stall for a Free Vortex Wake Model of a Floating Offshore Wind Turbine
Creators: name: Gaertner, Evan M
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: Floating offshore wind turbines in deep waters offer significant advantages to onshore and near-shore wind turbines. However, due to the motion of floating platforms in response to wind and wave loading, the aerodynamics are substantially more complex. Traditional aerodynamic models and design codes do not adequately account for the floating platform dynamics to assess its effect on turbine loads and performance. Turbines must therefore be over designed due to loading uncertainty and are not fully optimized for their operating conditions. Previous research at the University of Massachusetts, Amherst developed the Wake Induced Dynamics Simulator, or WInDS, a free vortex wake model of wind turbines that explicitly includes the velocity components from platform motion. WInDS rigorously accounts for the unsteady interactions between the wind turbine rotor and its wake, however, as a potential flow model, the unsteady viscous response in the blade boundary layer is neglected. To address this concern, this thesis presents the development of a Leishman-Beddoes dynamic stall model integrated into WInDS. The stand-alone dynamic stall model was validated against two-dimensional unsteady data from the OSU pitch oscillation experiments and the coupled WInDS model was validated against three-dimensional data from NREL’s UAE Phase VI campaign. WInDS with dynamic stall shows substantial improvements in load predictions for both steady and unsteady conditions over the base version of WInDS. Furthermore, use of WInDS with the dynamic stall model should provide the necessary aerodynamic model fidelity for future research and design work on floating offshore wind turbines.

description: Using the canonical JSJ splitting, we describe the outer automorphism group $\Out(G)$ of a one-ended word hyperbolic group $G$. In particular, we discuss to what extent $\Out(G)$ is virtually a direct product of mapping class groups and a free abelian group, and we determine for which groups $\Out(G)$ is infinite. We also show that there are only finitely many conjugacy classes of torsion elements in $\Out(G)$, for $G$ any torsion-free hyperbolic group. More generally, let $Γ$ be a finite graph of groups decomposition of an arbitrary group $G$ such that edge groups $G_e$ are rigid (i.e\. $\Out(G_e)$ is finite). We describe the group of automorphisms of $G$ preserving $Γ$, by comparing it to direct products of suitably defined mapping class groups of vertex groups.

description: AGE IDENTITY AND COGNITION IN OLD AGEWe read with great interest the research report by M.H. Schafer and T.P. Shippee in the January 2010 issue of The Journals of Gerontology: Social Sciences (Schafer & Shippee, 2010). The authors contribute several key findings to the literature on age identity in middle-aged to younger-old subjects (55-74 years), perhaps the most important being that younger age identities lead to more optimistic personal dispositions about cognitive aging. Over the past three years, we have anecdotally noted a similar phenomenon, in which subjects in our research program on healthy aging (O’Connor, et al., 2009; O’Connor, et al., 2015) report feeling much younger than their chronological age. We would like to use this commentary to report preliminary findings that compliment and extend the authors’ conclusions on age identity in healthy older individuals, those in their 80s, 90s, and 100s. In particular, we present new data about actual cognitive performance and age identity in our group of very old subjects (Leonard, et al.,. 2010).In summary, as with the Schafer and Shippee study, our preliminary data on age identity in the oldest of old individuals show that feeling much younger than one’s chronological age is related not only to one’s perceptions about one’s cognitive abilities but also to objectively measured cognitive function.
'Choose a Language Like a Wedding Ring': Polysystems, Norms and Pseudotranslation in Lea Goldberg’s Poetry & Prose
Creators: name: RANGELL, BENJAMIN
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Lea Goldberg [1911-1970] is one of modern Hebrew literature’s most significant poet/translators. This thesis approaches her early poetry and prose from the perspective of three theories of translation. ‘Polysystems’, ‘norms’, and ‘pseudotranslation’ grew from the scholarly and translation-lineage in Hebrew literary studies that Goldberg herself contributed to. Utilizing these three methods of reading, this thesis argues that translation’s thematization in Goldberg’s creative work is evidence for the poet’s ideal for a cosmopolitan, multilingual, national literature in the new Jewish State. This receptive stance to previous and concurrent literary traditions was met with much skepticism and criticism from Goldberg’s colleagues, and as a result, Goldberg’s oeuvre occupies a more peripheral position than several of her contemporaries.

description: Dark sector may couple to the Standard Model via one or more mediator particles. We discuss two types of mediators: the dark photon $A^{\prime}$ and the dark scalar mediator $ϕ$. The total cross-sections and various differential distributions of the processes $e^{+} e^{-} \rightarrow q \bar{q} A^{\prime}$ and $e^{+} e^{-} \rightarrow q \bar{q} ϕ$ ($q=u,~d,~c,~s$ and $b$ quarks) are discussed. We focus on the study of the invisible $A^{\prime}$ due to the cleaner background at future $e^{+} e^{-}$ colliders. It is found that the kinematic distributions of the two-jet system could be used to identify (or exclude) the dark photon and the dark scalar mediator, as well as to distinguish between them. We further study the possibility of a search for dark photons at a future CEPC experiment with $\sqrt{s}=$ 91.2 GeV and 240 GeV. With CEPC running at $\sqrt{s}=$ 91.2 GeV, it would be possible to perform a decisive measurement of the dark photon (20 GeV $< m_{A^{\prime}}

description: Large area catalogs of galaxy clusters constructed from ROSAT All Sky Survey provide the base for our knowledge on the population of clusters thanks to the long-term multiwavelength efforts on their follow-up. Advent of large area photometric surveys superseding in depth previous all-sky data allows us to revisit the construction of X-ray cluster catalogs, extending the study to lower cluster masses and to higher redshifts and to provide the modelling of the selection function. We perform a wavelet detection of X-ray sources and make extensive simulations of the detection of clusters in the RASS data. We assign an optical richness to each of the 24,788 detected X-ray sources in the 10,382 square degrees of SDSS BOSS area, using redMaPPer version 5.2. We name this survey COnstrain Dark Energy with X-ray (CODEX) clusters. We show that there is no obvious separation of sources on galaxy clusters and AGN, based on distribution of systems on their richness. This is a combination of increasing number of galaxy groups and their selection as identification of an X-ray sources either by chance or due to groups hosting an AGN. To clean the sample, we use a cut on the optical richness at the level corresponding to the 10\% completeness of the survey and include it into the modelling of cluster selection function. We present the X-ray catalog extending to a redshift of 0.6 down to X-ray fluxes of $10^{-13}$ ergs s$^{-1}$ cm$^{-2}$. We provide the modelling of the sample selection and discuss the redshift evolution of the high end of the X-ray luminosity function (XLF). Our results on $z<0.3$ XLF are in agreement with previous studies, while we provide new constraints on the $0.3

Prospects of measuring $\sin^2 2Θ_{13}$ and the sign of $Δm^2$ with a massive magnetized detector for atmospheric neutrinos

Year: 2002

description: The pattern of oscillation parameters emerging from current experimental data can be further elucidated by the observation of matter effects. In contrast to planned experiments with conventional neutrino beams, atmospheric neutrinos offer the possibility to search for Earth-induced matter effects with very long baselines. Resonant matter effects are asymmetric on neutrinos and anti-neutrinos, depending on the sign of $Δm^2$. In a three-generation oscillation scenario, this gives access to the mass hierarchy of neutrinos, while the size of the asymmetry would measure the admixture of electron neutrinos to muon/tau neutrino oscillations (the mixing angle $Θ_{13}$). The sensitivity to these effects is discussed after the detailed simulation of a realistic experiment based on a massive detector for atmospheric neutrinos with charge identification. We show how a detector, which measure and distinguish between $ν_μ$ and $\barν_μ$ charged current events, might be sensitive to matter effects using atmospheric neutrinos, provided the mixing angle $Θ_{13}$ is large enough.

description: The structure of the pseudo-binary mercury chalcogenide alloy HgSe0.7S0.3 has been studied by means of X-ray and neutron powder diffraction at pressures up to 8.5 GPa. A phase transition from the cubic zinc blende structure to the hexagonal cinnabar structure was observed at P ~ 1 GPa. A phenomenological model of this reconstructive phase transition based on the displacement mechanism is proposed. The analysis of the geometrical relationship between the zinc blende and the cinnabar phases has shown that the possible order parameter for the zinc blende - cinnabar structural transformation is the spontaneous strain e4. This assignment agrees with the previously observed high pressure behaviour of the elastic constants of some mercury chalcogenides.

The ways to optimize E853 are analyzed.

Sex Differences in Oligodendrocyte Development: Potential Implications for the Effect of Alcohol Drinking on Myelin.
Creators: name: Scott, Samuel
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Adolescence is a period of time when the brain undergoes profound development. Myelination is a maturational process in which oligodendroglia project out lipid-rich ramifications which wrap and insulate axons. This is crucial for effective neurotransmission between brain regions and, if compromised by pharmacological insults such as alcohol, can have long-term implications on behavior and cognition. We have previously shown that adolescent alcohol impacts males and females differentially, however it remains unknown how alcohol impacts oligodendroglia during development. The goal of this study was to determine the cellular dynamics of the oligodendroglia in male and female mice through development with and without alcohol exposure. Our results suggest that sexually dimorphic temporal dynamics exist within oligodendroglia. Specifically, this population of cells is notably dynamic during adolescence in males while stable in females. In addition, preliminary studies show that alcohol may cause a restriction on differentiation of oligodendroglia in male but not female mice. Further understanding of sex differences in the mechanisms of alcohol-induced change to oligodendroglia development could create the foundation for targeted, specific therapeutic agents and allow for individualized treatment of patients suffering from alcohol use disorders and potentially other addictions.
NEW WINE IN AN OLD BOTTLE: PROPAGANDA AND ADAPTATION OF THE WHITE-HAIRED GIRL IN POST-SOCIALIST CHINA
Creators: name: Shin, Ha Yeon
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: One of the well-known Chinese revolutionary classics The White-Haired Girl (baimaonü, 白毛女) has gone through different adaptations as a propaganda of Chinese Communist Party from the 1940s to the 1960s. In recent years, the 2011 and 2015 operas are presented by the Ministry of Culture. The 2015 opera became especially widely known for Xi Jinping’s wife, Peng Liyuan’s involvement as an artistic director. What is the purpose of remaking this outdated propaganda in post-socialist China? How can these new adaptations work effectively as a means of propaganda? My study on the new adaptations of the White-Haired Girl (hereafter WHG) can serve as an example of the changes of the propaganda in the age of post-socialism. To do so, this study will use the 2011 opera and the TV reportage program which analyzes the 2011 and 2015 opera in the following ways: examine the 2011 opera as a representative work of the 21stcentury adaptations and focus on the TV reportage program Cultural Focus (Wenhuashidian, 文化视点) which demonstrates the intention of the production through interviewing the main artists and staffs of the 2011 and 2015 operas, and the Chinese public. By doing so, I argue that the emphasis of propaganda is switched from class struggle to social harmony in the 2011 and 2015 operas compared to the film (1950) and the ballet film (1971). This social harmony is achieved by promotion of familial and generational harmony. Also, the heroine, Xi’er is represented as a female individual who can contribute to the unification of the nation instead of being presented as a class subject. In this regard, the endeavor of seeking social harmony through new adaptations reflects anxieties over social disintegration in contemporary China.

description: We perform a new calculation of the hadronic contributions, $a({\rm Hadronic})$ to the anomalous magnetic moment of the muon, $a_μ$. For the low energy contributions of order $α^2$ we carry over an analysis of the pion form factor $F_π(t)$ using recent data both on $e^+e^-\toπ^+π^-$ and $τ^+\to \barν_τπ^+π^0$. In this analysis we take into account that the phase of the form factor is equal to that of $ππ$ scattering. This allows us to profit fully from analyticity properties so we can use also experimental information on $F_π(t)$ at spacelike $t$. At higher energy we use QCD to supplement experimental data, including the recent measurements of $e^+e^-\to {\rm hadrons}$ both around 1 GeV and near the $\bar{c}c$ threshold. This yields a precise determination of the $O(α^2)$ and $O(α^2)+O(α^3)$ hadronic part of the photon vacuum polarization pieces, $$10^{11}\times a^{(2)}({\rm h.v.p.})=6 909\pm64;\quad 10^{11}\times a^{(2+3)}({\rm h.v.p.})=7 002\pm66$$ As byproducts we also get the masses and widths of the $ρ^0, ρ^+$, and very accurate values for the charge radius and second coefficient of the pion. Adding the remaining order $α^3$ hadronic contributions we find $$10^{11}\times a^{\rm theory}(\hbox{Hadronic})= 6 993\pm69\quad(e^+e^- + τ+ {\rm spacel.})$$ The figures given are obtained including $τ$ decay data. This is to be compared with the recent experimental value, $$10^{11}\times a^{\rm exp.}(\hbox{Hadronic})=7 174\pm150.$$

description: We calculate the $\mathcal{O}(α)$ weak corrections to top quark pair production at the LHC and include anomalous electroweak interactions from dimension-six operators. The loop calculation and renormalization are consistently done within the Standard Model Effective Field Theory. Sensitivity to the involved operators is exposed through the virtual corrections, which receive enhancement from electroweak Sudakov logarithms. We investigate the prospects of using this feature for probing New Physics at the LHC that so far has only been studied in final states with on-shell sensitivity such as $t\bar{t}+Z$ or $t \to b W$. We find that the large $t\bar{t}$ production rate and the excellent perturbative control allow compensating the loop suppression and yield remarkably strong constraints that are competitive with those from $t\bar{t}+Z$.

La valoracion multicriterio permite soslayar ambas cuestiones. Este trabajo propone la aplicacion de dicha metodologia para la valoracion de empresas, desarrollando un caso de estudio en el que se valora una empresa bodeguera espanola no cotizada en bolsa: Vinas del Vero. Ademas del ambito de aplicacion, entre las novedades del trabajo esta la modificacion del modelo de Programacion por Metas empleado en anteriores referencias sobre valoracion multicriterio, lo que permite obtener mejores ajustes, y el empleo de matrices incompletas en los cuestionarios utilizados en el Proceso Analitico Jerarquico, lo qu reduce el coste de obtencion de los mismos. One drawback in valuation models is the huge information required in order to be applied in real problems, as well as the difficult to include qualitative variables in the valuation process. Multicriteria valuation handles these two problems. This work proposes multicriterio methodology for the valuation of firms, and develops a case study for a non-quoted Spanish wine-producer firmL Vinas del Vero. We must emphasize some innovation aspects of our paper: the modification of the original Goal Programming model, which assures more adjusted results, and the use of incomplete matrices in the Analytic Hierarchy Process, very useful for cost reduction.
How Perception of Decision Environment and Future Information Affects Changes in Delay Discounting Rates: Differences Across U.S. and China, Differences Before and After the U.S. 2018 Midterm Elections
Creators: name: Walsh, Fran
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: In this thesis, I will explore the idea that choices between present, smaller value options and future, larger value options depend on how much individuals trust the future to deliver the reward. Due to this aspect of trust, the individual must build their estimate of trust based on information for their present environment and their future expectations. This estimate of future trust can change across different time points in the same environment (i.e., before and after a national election) and between environments in the same time point (i.e., between two countries experiencing different economic rates of change). In this set of presented experiments, I will explore the link between decision environment and delay discounting, as well as the relationship between the contents of future perception and delay discounting. These two experiments will test differences in delay discounting (a) across two economic systems (China and the U.S.), as well as (b) before and after a national election (2018 U.S. Midterms). The results of the different decision environments study show that the delay discounting rates are significantly different across the two countries, specifically within the framing of present and future. These differences are not explained by differences in culture effects or individual differences in personality traits, suggesting that difference in environment is driving the effect. The results from the Midterm election experiments show evidence for differences in delay discounting between political identities and income groups. There are also differences in how these two groups perceive the contents of their future before and after the election. Specifically with evidence that negative future projection corresponds with increased delay discounting. Overall, these experiments show that delay discounting can be affected by the way information is framed within an environment and how we expect our environments to change over time.

description: We report the phenomenon of frequency clustering in a network of Hodgkin-Huxley neurons with spike timing-dependent plasticity. The clustering leads to a splitting of a neural population into a few groups synchronized at different frequencies. In this regime, the amplitude of the mean field undergoes low-frequency modulations, which may contribute to the mechanism of the emergence of slow oscillations of neural activity observed in spectral power of local field potentials or electroencephalographic signals at high frequencies. In addition to numerical simulations of such multi-clusters, we investigate the mechanisms of the observed phenomena using the simplest case of two clusters. In particular, we propose a phenomenological model which describes the dynamics of two clusters taking into account the adaptation of coupling weights. We also determine the set of plasticity functions (update rules), which lead to multi-clustering.
Increased Body Weight in Adulthood Following a Peripubertal Stressor and Proposed Mechanism for Effects of Increased Adiposity on Estrogen-dependent Behaviors

description: Exposure to certain stressors during a sensitive period around puberty can lead to enduring effects on an animal’s response to estradiol. In estradiol-influenced behaviors, such as sexual receptivity, hippocampal-dependent learning and memory, depression-like behavior, and anxiety-like behaviors, exposure to a peripubertal stressor such as shipping stress or an injection of lipopolysaccharide (LPS) can eliminate or even reverse the normal response to estradiol. In addition to regulating these behaviors, estradiol play a role in the regulation of body weight. While some of the previous studies touched on short-term effects on body weight, no systemic long-term study of the effects of a peripubertal stressor on body weight, particularly without interruption by ovariectomy, have been undertaken. This paper introduces a hypothesis that proposes that increased adiposity following exposure to a peripubertal stressor leads to the changes to estrogen-dependent behaviors through altered levels of estrogens and changes to estrogen receptors. The first chapter examines body weight data collected during studies with other aims, and then proposes an experiment to test whether either of two peripubertal stressors results in increased weight gain and body weight. The following chapter proposes further experiments designed to determine the proximate mechanisms leading to weight gain following peripubertal stressors and the role of diet on weight gain. The final chapter proposes experiments to test the effects of adiposity on peripheral levels of testosterone, aromatase, estradiol, and estrone; central levels of estradiol and estrone; and estrogen receptors in the brain.

description: This thesis explores the extent to which the Holocaust shaped British antifascism in the period 1945-1967. It makes an original contribution in setting out the first dedicated analysis of the relationship between consciousness of the Nazi genocide and motivations for confronting fascism in Britain. The study has interrogated institutional archival records to assess the presence of the Holocaust in the private discourses, propaganda and campaign strategies of a wide variety of antifascist organisations. Personal motivations for antifascist activism have been engaged with through analysis of memoirs, autobiographies and oral histories. The thesis will demonstrate that the Holocaust was often absent from antifascist rhetoric, and so should be decentred from understandings that assume constant affinity between Holocaust remembrance and British antifascism. Instead, antifascism in this period was often conceptualised in a patriotic framework, as coda to the Second World War, or viewed through left-wing analyses of class struggle which obscured fascism’s ‘racial’ victims. However, the central importance of this study lies in its revealing that a Holocaust-inspired resistance to fascism was emerging in this period and beginning to co-exist with patriotic and other forms of antifascism. The ‘lessons’ of the Holocaust for antifascists were the subject of agonised internal disputes and became a point of open conflict between militant and establishment Anglo-Jewish organisations. The genocide was also politicised in a number of antifascist campaigns, including on the Left and in the name of civil liberties. The thesis therefore argues for 1945-67 as a vital transitional period when use of the Holocaust as a weapon against fascism was developing, albeit sometimes on the fringes of antifascist discourse. In this way, the period presaged the more confident later invocations of the genocide, including in activism against the National Front in the 1970s.

description: We study the phase space structure of exact quantum Wightman functions in spatially homogeneous, temporally varying systems. In addition to the usual mass shells, the Wightman functions display additional coherence shells around zero frequency $k_0=0$, which carry the information of the local quantum coherence of particle-antiparticle pairs. We find also other structures, which encode non-local correlations in time, and discuss their role and decoherence. We give a simple derivation of the cQPA formalism, a set of quantum transport equations, that can be used to study interacting systems including the local quantum coherence. We compute quantum currents created by a temporal change in a particle's mass, comparing the exact Wightman function approach, the cQPA and the semiclassical methods. We find that the semiclassical approximation, which is fully encompassed by the cQPA, works surprisingly well even for very sharp temporal features. This is encouraging for the application of semiclassical methods in electroweak baryogenesis with strong phase transitions.

 Female microptera. Body and legs brown to dark brown, all tarsi, apices of tibiae and median area of head paler; antennal segments I–II and V–IX brown, III–IV brownish-yellow. Head wider than long, with transverse sculpture behind eyes but none near ocelli (Fig. 109); ocelli reduced, ocellar setae III within or near anterior margins of triangle; eyes without pigmented facets. Antennae 9-segmented; III–IV with small forked sensorium; II without microtrichia; VI with base narrowed and weakly pedicellate (Fig. 111). Pronotum with transverse striae, but few small setae. Meso and metascutum transverse, campaniform sensilla present (Fig. 112). Fore wing lobe scarcely longer than metascutal length. Abdominal tergites I–VII with transverse sculpture lines medially, VIII almost without sculpture; VIII with posteromarginal comb of irregular, short and partially fused microtrichia, spiracles occupying half of lateral margin of tergite (Fig. 113); tergal setae S3 and S4 no longer than S1 and S2; setae on IX shorter than dorsal length of tergite X. Sternites with a few short microtrichia on sculpture lines laterally; setae S1 on VII close to posterior margin.

description: The action principle by Low [Proc. R. Soc. Lond. A 248, 282--287] for the classic Vlasov-Maxwell system contains a mix of Eulerian and Lagrangian variables. This renders the Noether analysis of reparametrization symmetries inconvenient, especially since the well-known energy- and momentum-conservation laws for the system are expressed in terms of Eulerian variables only. While an Euler-Poincaré formulation of Vlasov-Maxwell-type systems, effectively starting with Low's action and using constrained variations for the Eulerian description of particle motion, has been known for a while [J. Math. Phys., 39, 6, pp. 3138-3157], it is hard to come by a documented derivation of the related energy- and momentum-conservation laws in the spirit of the Euler-Poincaré machinery. To our knowledge only one such derivation exists in the literature so far, dealing with the so-called guiding-center Vlasov-Darwin system [Phys. Plasmas 25, 102506]. The present exposition discusses a generic class of local Vlasov-Maxwell-type systems, with a conscious choice of adopting the language of differential geometry to exploit the Euler-Poincaré framework to its full extent. After reviewing the transition from a Lagrangian picture to an Eulerian one, we demonstrate how symmetries generated by isometries in space lead to conservation laws for linear- and angular-momentum density and how symmetry by time translation produces a conservation law for energy density. We also discuss what happens if no symmetries exist. Finally, two explicit examples will be given -- the classic Vlasov-Maxwell and the drift-kinetic Vlasov-Maxwell -- and the results expressed in the language of regular vector calculus for familiarity.
