description: Pair density wave superconductivity constitutes a novel electronic condensate proposed to be realized in certain unconventional superconductors. Establishing its potential existence is important for our fundamental understanding of superconductivity in correlated materials. Here we compute the dynamical magnetic susceptibility in the presence of a pair density wave ordered state, and study its fingerprints on the spin-wave spectrum including the neutron resonance. In contrast to the standard case of d-wave superconductivity, we show that the pair density wave phase exhibits neither a spin-gap nor a magnetic resonance peak, in agreement with a recent neutron scattering experiment on underdoped La$_{1.905}$Ba$_{0.095}$CuO$_4$ [Z. Xu et al., Phys. Rev. Lett. 113, 177002 (2014)].

description: The present study aims to explore the decision-making strategies that human operators use in an automation-aided signal detection task. While past research has demonstrated that human operators reach suboptimal levels of collaborative performance when assisted by automated decision aids, it is unclear what decision processes the operators are using, and what information is required to be presented by an aid to reach best possible performance. To inform automation design, it is of interest how human operators interact with an automated aid, either through simple heuristics or more deliberate integrative strategies.
GENETIC VARIATION FOR FRUIT DEVELOPMENT OF PISUM SATIVUM L., WITH SPECIAL REFERENCE TO THE EFFECTS OF THE RUGOSUS LOCUS
Creators: name: SMITH, CHRISTINE MARY
Publisher: name: University of Plymouth
Year: 1986

description: This study has compared various aspects of pea fruit development, using two green-podded lines near-isogenic except for the r locus and a yellow-podded mutant having the genotype gpgp. The gp gene is associated with reduced chlorophyll in the pod wall which then appears yellow. The r gene is associated with a wrinkled appearance of mature dried seed and cotyledonary starch grains which are small and fissured. An ultrastructural survey of tissues from pods, testas and cotyledons showed there to be no effect of the r locus on chloroplast structure. The structure of amyloplasts however, appeared to be affected by the r locus; starch grains in the cotyledons having a rugged outline in the wrinkled type. Chloroplasts from the inner tissues of the yellow pod were similar to those in leaves, green pods, green-podded testas and cotyledons. Chloroplasts in the yellow pod mesocarp and in the testa of yellow pods had dilated thylakoids, less starch and more lipid than the green-podded types. Growth analysis of the near-isogenic lines showed there to be no difference between the round (RR) and wrinkled (rr) lines in pod and testa growth, but embryo growth differed. The wrinkled embryo contained more water during development but had a lower final dry weight than the round embryos. Water potential (an indication of the osmotic regulation) was lower in the wrinkled embryos than in the round embryos, except very early in development when it was higher in the wrinkled embryos. In vitro culture of embryos showed that optimum growth was obtained in liquid media containing 10% sucrose as a carbon source. Replacing sucrose with mannitol determined that it was the sucrose which was important, not its resulting water potential. These gp and r gene effects and their relevance to future breeding programmes are discussed with other biochemical studies on similar genotypes.
Greening Africa-China Relations: African Agents Punching Below their Weight?

description: China is changing the global metabolism of goods and resources. In the last few decades, China has launched an unprecedented and unparalleled economic engagement with Africa. The level of Chinese investment on the continent is still very low relative to its investment in other regions whereas, for many African countries, China has already become the leading trading partner in terms of both import and export business. In fact, China has surpassed the U.S.A. as the single largest trading partner of Africa in 2009. One key area of debate in this evolving relationship has been the growing environmental footprint of the partnership. Unlike in the past, environmental issues have now taken center stage in world politics mainly due to the increasingly daunting challenges nations are confronted with in terms of environmental and climate change crises. It has taken China quite some time to realize that environmental protection is a matter of survival and not a luxury. Hence, the Government of China has been issuing rules, regulations, and guidelines to encourage more sustainable economic development. Corporate Social Responsibility (CSR) has been vigorously introduced to the business sector since the mid-2000s in an attempt to achieve this objective. The outcome of this policy direction has been positive in that many businesses have been forced to adhere to the strict guidelines; it also reflects burgeoning social activism against pollution and environmental destruction at home. This has, however, had its downside because companies started to expand to regions with poor governance and weak environmental regulations, notably Africa. There is already some evidence that Chinese investment in Africa, if not regulated properly, would repeat the history of pollution in China. This article argues that the limited success that CSR has registered in China could be repeated in Africa only when African states start to engage strategically with rising powers like China. African governments need to strictly enforce environmental policy and empower non-state actors, particularly civil society organizations (CSOs), to actively monitor developments and safeguard the environment.

description: Abstract Background With the focus of global and national family planning initiatives on reaching “additional user” targets, it is increasingly important for programs to assess contraceptive method discontinuation and switching. This analysis calculated the discontinuation rate and method-specific discontinuation rates, examined reasons given for contraceptive discontinuation, and assessed characteristics associated with subsequent contraceptive switching and abandonment among women living in urban areas of Senegal. Methods Data came from the Measurement, Learning & Evaluation project’s 2015 survey of 6927 women of reproductive age living in six urban sites (Dakar, Pikine, Guédiawaye, Mbao, Kaolack and Mbour). Information on contraceptive use and discontinuation for the five years preceding the survey were recorded in a monthly calendar. Single decrement life tables were used to calculate discontinuation rates. Descriptive analyses were used to assess reasons for discontinuation and method switching after discontinuation. A multinomial logistic regression was used to estimate the likelihood of being a non-user in-need of contraception, a non-user not in-need of contraception, or a method switcher in the month after discontinuation, by sociodemographic and other characteristics. Results The 12-month discontinuation rate for all methods was 34.7%. Implants had the lowest one-year discontinuation rates (6.3%) followed by the intrauterine device (IUD) (18.4%) while higher rates were seen for daily pills (38%), injectables (32.7%), and condoms (62.9%). The most common reasons for discontinuation were reduced need (45.6%), method problems (30.1%), and becoming pregnant while using (10.0%). Only 17% of discontinuations were followed by use of another method; most often daily pills (5.2%) or injectables (4.2%). In the multivariate analysis, women with any formal education (primary, secondary or higher) were more than 50% more likely to switch methods than remain in need of contraception after discontinuation than women with no education or Koranic-only education (RRR = 1.59, p-value = 0.004; RRR = 1.55, p-value = 0.031). The likelihood of switching compared to being “in need” was also significantly higher for women who were married and who discontinued traditional methods. Conclusions To support increased contraceptive method use, women with no education and unmarried women are priorities for counseling and information about side effects and method switching at the time of method adoption.
Chinese and Western Interpretations of China's "Peaceful Development" Discourse: A Rule-Oriented Constructivist Perspective
Creators: name: Jing, Jing
Publisher: name: Journal of China and International Relations
Year: 2014

description: This paper offers a rule-oriented constructivist perspective on understanding the distinct Chinese and western interpretations of China's "peaceful development" discourse framework. It takes the correlations of discourse, rules and rule initiated by Nicolas Onuf as an analytical tool to identify the discrepancies between and within the Chinese and western patterns of discourse, rules and rule on this issue. Critical analyses of Chinese and western discourse are provided as a source for understanding the lack of trust between China and the West on China's "peaceful development". This methodology, which synthesizes the rule-oriented constructivist perspective and concrete discourse analysis, is an innovated attempt to implement the conventional positivist perspective on this issue.

description: We report on a multiwavelength observational campaign of the black hole X-ray binary Swift J1753.5-0127 that consists of an ESO/X-shooter spectrum supported by contemporaneous Swift/XRT+UVOT and ATCA data. ISM absorption lines in the X-shooter spectrum allows us to determine E(B-V)=0.45+/-0.02 along the line-of-sight to the source. We also report detection of emission signatures of He II at 4686 angstrom, H alpha, and, for the first time, H I at 10906 angstrom and Paschen Beta. The double-peaked morphology of these four lines is typical of the chromosphere of a rotating accretion disk. Nonetheless, the paucity of disk features points towards a low level of irradiation in the system. This is confirmed through spectral energy distribution modeling and we find that the UVOT+X-shooter continuum mostly stems from the thermal emission of a viscous disk. We speculate that the absence of reprocessing is due to the compactness of an illumination-induced envelope that fails to reflect enough incoming hard X-ray photons back to the outer regions. The disk also marginally contributes to the Compton-dominated X-ray emission and is strongly truncated, with an inner radius about a thousand times larger than the black hole's gravitational radius. A near-infrared excess is present, and we associate it with synchrotron radiation from a compact jet. However, the measured X-ray flux is significantly higher than what can be explained by the optically thin synchrotron jet component. We discuss these findings in the framework of the radio quiet versus X-ray bright hypothesis, favoring the presence of a residual disk, predicted by evaporation models, that contributes to the X-ray emission without enhancing the radio flux.

description: Parton energy loss, quarkonium sequential melting and particle production from electromagnetic interactions are tools to study Quark Gluon Plasma properties. The STAR detector, with large acceptance at mid-rapidity, excellent particle identification and wide transverse momentum coverage, is able to study these probes in details. In Hard Probes 2015, the STAR collaboration reported measurements of reconstructed jets, heavy-flavor physics, di-lepton production and the performance of new detectors in seven presentations and one poster. Given the rich results from STAR, this overview report will focus on a few selected results on jets and $Υ$ measurements in Au+Au collisions at $\sqrt{s_{\rm NN}}=200\,$GeV, $J/ψ$ production in $p$+$p$ collisions at $\sqrt{s_{\rm NN}}=500\,$GeV, and the di-electron spectrum in the low mass region from the Beam Energy Scan - Phase I.

description: Abstract Background. It is well acknowledged that glucocorticoid (GC) replacement can unmask diabetes insipidus (DI) in subjects with hypopituitarism. Objective. To increase the awareness and monitoring for transient and symptomatic DI in children with partial hypopituitarism during periods in which increased GC needs are required. Methods/Case. A 2-month-old female infant with septo-optic dysplasia (SOD; on thyroid and maintenance GC replacement therapy at 8 mg/m2/day) developed transient DI during 2 separate episodes of stress (one hypothermia, one febrile) when stress dosing of GC (25 mg/m2/day) was instituted. Conclusion. Children not diagnosed with DI during initial evaluation for hypopituitarism may benefit from rescreening of serum sodium levels during acute periods of stress that demand "stress" GC dosing. This will permit treatment and/or increased vigilance for ensuing permanent DI.

In recent years Aalborg University has seen a progressive PBL development with regard to our many new continuing educational programs. The empirical data applied in the article is collected from two qualitative Ph.D. studies. Drawing on research findings from these studies, we discuss why the PBL model, in spite of the intentions of closing the gap between education and working life, seems to have some important challenges. The discussion concludes by suggesting some pedagogical guidelines for the design of future PBL organized academic activities within continuing education.

description: The joint project FAIR Data Spaces aims to build a common Data Space for industry and science. In doing so, it brings together the two initiatives Gaia-X and the National Research Data Infrastructure (NFDI). But how can these existing initiatives from both worlds be brought together to share data and knowledge across the boundaries of these different domains? How can synergies and fruitful collaborations emerge? FAIR Data Spaces aims to build a shared community by linking the initiatives organizationally, legally, technically, and practically. This enables the creation of building blocks for overarching data spaces based on the common FAIR principles, which will serve as nuclei for a fair data economy. Building on existing infrastructure and data services, the project develops use cases, also called demonstrators, for three data spaces: Biodiversity, Research Data Quality Assurance, and Cross-Platform Data Analysis. The data flows in the individual demonstrators are analysed in terms of data protection and intellectual property rights. The poster presents FAIR Data Spaces and the current project results with focus on the three demonstrators that are discussed in more detail in the following.

description: We reported the optical observations of GRB 121011A by 0.8-m TNT telescope at Xinglong observatory, China. The light curve of optical afterglow shows a smooth and featureless bump during the epoch of $\sim$130 sec and $\sim$5000 sec with a rising index of $1.57\pm0.28$ before the break time of $539\pm44$ sec, and a decaying index of about $1.29\pm0.07$ up to the end of our observations. Meanwhile, the X-ray light curve decays in a single power-law with a slop of about $1.51\pm0.03$ observed by $XRT$ onboard ${\rm} Swift$ from 100 sec to about 10000 sec after the burst trigger. The featureless optical light curve could be understood as an onset process under the external-shock model. The typical frequency has been below or near the optical one before the deceleration time, and the cooling frequency is located between the optical and X-ray wavelengths. The external medium density has a transition from a mixed stage of ISM and wind-type medium before the peak time to the ISM at the later phase. The joint-analysis of X-ray and optical light curves shows that the emission from both frequencies are consistent with the prediction of the standard afterglow model without any energy injections, indicating that the central engine has stopped its activity and does not restart anymore after the prompt phase.

description: High-scale string inflationary models are in well-known tension with low-energy supersymmetry. A promising solution involves models where the inflaton is the volume of the extra dimensions so that the gravitino mass relaxes from large values during inflation to smaller values today. We describe a possible microscopic origin of the scalar potential of volume modulus inflation by exploiting non-perturbative effects, string loop and higher derivative perturbative corrections to the supergravity effective action together with contributions from anti-branes and charged hidden matter fields. We also analyse the relation between the size of the flux superpotential and the position of the late-time minimum and the inflection point around which inflation takes place. We perform a detailed study of the inflationary dynamics for a single modulus and a two moduli case where we also analyse the sensitivity of the cosmological observables on the choice of initial conditions.

description: We present results from a Hubble Space Telescope (HST) program characterizing the atmospheres of the outer two planets, in the HR8799 system. The images were taken over 15 orbits in three near-infrared medium-band filters - F098M, F127M and F139M - using the Wide Field Camera 3. One of the three filters is sensitive to water absorption band inaccessible from ground-based observations, providing a unique probe of the thermal emission from the atmospheres of these young giant planets. The observations were taken at 30 different spacecraft rolls to enable angular differential imaging, and the full data set was analyzed with the Karhunen-Loeve Image Projection (KLIP) routine, an advanced image processing algorithm adapted to work with HST data. To achieve the required high contrast at sub arcsecond resolution, we utilized the pointing accuracy of HST in combination with an improved pipeline designed to combine the dithered, angular differential imaging data with an algorithm designed to both improve the image resolution and accurately measure the photometry. The results include F127M ($J$) detections of the outer planets, HR8799 b and c and the first detection of HR8799 b in the water-band (F139M) filter. The F127M photometry for HR8799 c agrees well with fitted atmospheric models resolving a long standing difficulty to model the near-IR flux for the planet consistently

description: Abstract Background To evaluate the concordance between leisure-time sedentary behavior in adolescents assessed by an activity-based questionnaire and accelerometry. A convenience sample of 128 girls and 73 boys, 11-15 years of age (12.6 ± 1.1 years) from six states across the United States examined as part of the feasibility studies for the Trial of Activity in Adolescent Girls (TAAG). Three days of self-reported time spent watching TV/videos, using computers, playing video/computer games, and talking on the phone was assessed using a modified version of the Self-Administered Physical Activity Checklist (SAPAC). Criterion measure of sedentary behavior was via accelerometry over three days using a cut point of < 50 counts · 30 sec-1 epoch. Comparisons between sedentary behavior by the two instruments were made. Results Adolescents generally underestimated minutes of sedentary behavior compared to accelerometry-measured minutes. The overall correlation between minutes of sedentary behavior by self-report and accelerometry was weak (Spearman r = 0.14; 95% CI 0.05, 0.23). Adjustment of sedentary minutes of behavior for total minutes assessed using either percentages or the residuals method tended to increase correlations slightly. However, regression analyses showed no significant association between self-reported sedentary behavior and minutes of sedentary behavior captured via accelerometry. Discussion These findings suggest that the modified 3-day Self-Administered Physical Activity Checklist is not a reliable method for assessing sedentary behavior. It is recommended that until validation studies for self-report instruments of sedentary behavior demonstrate validity, objective measures should be used.

description: Motivated by several experimental efforts to understand spin diffusion and transport in ultracold fermionic gases, we study the spin dynamics of initially spin-polarized ensembles of harmonically trapped non-interacting spin-1/2 fermionic atoms, subjected to a magnetic field gradient. We obtain simple analytic expressions for spin observables in the presence of both constant and linear magnetic field gradients, with and without a spin-echo pulse, and at zero and finite temperatures. The analysis shows the relevance of spin-motional coupling in the non-interacting regime where the demagnetization decay rate at short times can be faster than the experimentally measured rates in the strongly interacting regime under similar trapping conditions. Our calculations also show that particle motion limits the ability of a spin-echo pulse to remove the effect of magnetic field inhomogeneity, and that a spin-echo pulse can instead lead to an increased decay of magnetization at times comparable to the trapping period.

description: In this study, we would like to follow a new research question that is possible to answer with data that will be collected in an already existing pre- registered experiment https://doi.org/10.17605/OSF.IO/MEJ6H. The current pre-registration is written after starting data collection, but prior to accessing or analysis of the data. We will use the data that will collect as specified in the above pre-registration to answer our new research question, as specified below. We would like to check for individual differences in the LBA’s DR parameter in perceptual and emotional tasks. Specifically, we hypothesize that participants who show relatively fast DR in the perceptual task, would also show relatively fast DR in the emotion task (and vice versa for relatively slow DR). We will use hierarchical Bayesian LBA model to model the data, using the ‘ggdmc’ R package (Lin & Strickland, 2020). This hierarchical method estimates parameters for each individual separately but constrain these estimations with the population distribution. To check the reliability of the model parameters, we will split each task data into two parts: odd numbered and even numbered trials. We will than crate the model parameters for each part separately and check the correlation between each pair of parameters (for example, in the emotional task we will estimate A twice, once for each part, and then check for the correlation between the two A estimated). The estimated reliabilities will be the Spearman-Brown boosted correlation (2*r/(1+r)). To answers our research question, we will use the LBA posterior parameters (averaged between the two parts) for each individual separately.

We expect to find that the correlation between DR for the emotional task and DR for the perceptual task will be the highest positive correlation. Bibliography Lin, Y.-S., & Strickland, L. (2020).

description: Interest in interindividual variation in intraindividual psychological patterns has increased substantially in the psychological sciences. However, relatively little is known about the longitudinal stability of these intraindividual patterns — that is, their stationarity — or the implications of stationarity or lack thereof for inferences about individuals. In a set of three samples from two ILL datasets, we have shown, using heterogeneity tests (Merkle & Zeileis, 2013) fit to individual person mood data, that measurement noninvariance over time is common at the level of individuals, even on relatively short time scales. Moreover, the degree of noninvariance, as reflected in heterogeneity test statistics, is associated with decreased intraindividual associations of these mood variables with each other and other criteria, such that individuals who are less invariant in their response processes over time show decreased predictability. We aim to replicate these analyses with a preregistered analytic plan using preexisting data from the COGITO study (Schmiedek, et al., 2010; West, 2018). Specifically, we plan to fit psychometric models to COGITO mood data on an individual-by-individual basis, conduct tests of temporal measurement invariance over the time span of the study for each individual, and then examine associations between the degree of noninvariance for each person and intraindividual correlations among the mood variables.

description: The $R_h = ct$ cosmological model has received considerable attention in recent years owing to claims that it is favoured over the standard $Λ$ cold dark matter ($Λ$CDM) model by most observational data. A key feature of the $R_h = ct$ model is that the zero active mass condition $ρ+ 3p = 0$ holds at all epochs. Most recently, Melia has claimed that this condition is a requirement of the symmetries of the Friedmann-Robertson-Walker (FRW) spacetime. We demonstrate that this claim is false and results from a flaw in the logic of Melia's argument.

description: The accelerator FLUTE (name abbreviation derived from its German name: Ferninfrarot Linac- und TestExperiment) has been set up in cooperation with DESY and PSI [1]. The electron source and diagnostics has commenced operation. General safety issues of FLUTE are covered in this paper. The activation of the accelerator and vacuum parts were predicted previously [2]. The attention is given to the activation of aluminum and impurities in the electron absorber of the beam dump. Potential air activation in the experimental hall is also discussed.

description: We will study the role of syntactic and lexical information in the real-time interpretation of doubly-quantified sentences using a visual world paradigm. Doubly-quantified sentences like "Each of the wolves spotted a log" are ambiguous in terms of scope assignment: The universal quantifier "each" can be assigned wide scope over the existential quantifier "a" (the universal-wide interpretation, in which each wolf spots a different log), but the existential quantifier "a" can also be assigned wide scope over the universal quantifier "each" (the existential-wide interpretation, in which each wolf spotted the same log). The interpretation of such scopally ambiguous sentences relies on syntactic information: The quantifier that is presented first in the surface structure of the sentence is more likely to be assigned wide scope. In addition, the assignment of scope depends on lexical information: Particularly relevant for this experiment is that the quantifier each (e.g., "Each of the wolves spotted a log") is more likely to be assigned wide scope than the quantifier all (e.g., "All of the wolves spotted a log"; e.g., Feiman & Snedeker, 2016; Ioup, 1975). Please see the pdf of the full preregistration for details on the materials, procedure, planned analyses, and sampling plan. Note that this preregistered study is very similar to our previous preregistration in this project. The main deviation from this earlier study is that Quantifier (all vs each) is now manipulated within participants, whereas this was manipulated between quantifiers in our previously preregistered study.
Physical origin of the large-scale conformity in the specific star formation rates of galaxies

description: Two explanations have been put forward to explain the observed conformity between the colours and specific star formation rates (SFR/$M_*$) of galaxies on large scales: 1) the formation times of their surrounding dark matter halos are correlated (commonly referred to as "assembly bias"), 2) gas is heated over large scales at early times, leading to coherent modulation of cooling and star formation between well-separated galaxies (commonly referred to as "pre-heating") . To distinguish between the pre-heating and assembly bias scenarios, we search for relics of energetic feedback events in the neighbourhood of central galaxies with different specific star formation rates. We find a significant excess of very high mass ($\log M_* > 11.3$) galaxies out to a distance of 2.5 Mpc around low SFR/$M_*$ central galaxies compared to control samples of higher SFR/$M_*$ central galaxies with the same stellar mass and redshift. We also find that very massive galaxies in the neighbourhood of low SFR/$M_*$ galaxies have much higher probability of hosting radio loud active galactic nuclei. The radio-loud AGN fraction in neighbours with $\log M_* > 11.3$ is four times higher around passive, non star-forming centrals at projected distances of 1 Mpc and two times higher at projected distances of 4 Mpc. Finally, we carry out an investigation of conformity effects in the recently publicly-released Illustris cosmological hydrodynamical simulation, which includes energetic input both from quasars and from radio mode accretion onto black holes. We do not find conformity effects of comparable amplitude on large scales in the simulations and we propose that gas needs to be pushed out of dark matter halos more efficiently at high redshifts.

From flexoelectricity to absolute deformation potentials: The case of SrTiO$_3$

description: Based on recent developments in the first-principles theory of flexoelectricity, we generalize the concept of absolute deformation potential to arbitrary nonpiezoelectric insulators and deformation fields. To demonstrate our formalism, we calculate the response of the band edges of SrTiO$_3$ to both dynamic (sound waves) and static (bending) mechanical loads, respectively at the bulk level and in a slab geometry. Our results have important implications for the understanding of strain-gradient-related phenomena in crystalline insulators, formally unifying the description of band-structure and electrostatic effects.

Pattern of neuropsychological performance among HIV positive patients in Uganda
Creators: name: Robertson, Kevin R
Publisher: name: BioMed Central Ltd
Year: 2007

description: Abstract Background Few studies have examined cognitive functioning of HIV positive patients in sub-Saharan Africa. It cannot be assumed that HIV positive patients in Africa exhibit the same declines as patients in high-resource settings, since there are differences that may influence cognitive functioning including nutrition, history of concomitant disease, and varying HIV strains, among other possibilities. Part of the difficulty of specifying abnormalities in neuropsychological functioning among African HIV positive patients is that there are no readily available African normative databases. The purpose of the current study was to evaluate the pattern of neuropsychological performance in a sample of HIV positive patients in comparison to HIV negative control subjects in Uganda. Methods The neuropsychological test scores of 110 HIV positive patients (WHO Stage 2, n = 21; WHO Stage 3, n = 69; WHO Stage 4, n = 20) were contrasted with those of 100 control subjects on measures of attention/concentration, mental flexibility, learning/memory, and motor functioning. Results Analysis of covariance (ANCOVA) revealed significant group differences on measures of verbal learning and memory, speed of processing, attention and executive functioning between HIV seropositive and seronegative subjects. Conclusion Ugandan patients with HIV demonstrated relative deficits on measures of verbal learning and memory, speed of processing, attention, and executive functioning compared to HIV negative controls. These results from a resource limited region where clades A and D are prevalent are consistent with previous findings in the developed world where clade B predominates.

description: We present a comparison of two methods to compute the momentum spectrum and the Schwinger pair creation rate for pulsed rotating electric fields: one based upon the real-time Dirac--Heisenberg--Wigner (DHW) formalism and a semiclassical approximation based on a scattering ansatz. For the semiclassical method we propose to either perform numerical calculations or an additional approximation based on an analytical solution for the constant rotating field. We find that both numerical methods are complementary with respect to computation time as well as accuracy. The approximate method shows the same qualitative features while being computationally much faster. We additionally find that the unequal production of pairs in different spin states reported for constant rotating fields with the scattering method is in agreement with the Wigner function method.
