description: We describe a purely algebraic method for finding the best separable approximation to a mixed state of a composite 2x2 quantum system, consisting of a decomposition of the state into a linear combination of a mixed separable part and a pure entangled one. We prove that, in a generic case, the weight of the pure part in the decomposition equals the concurrence of the state.

description: Quantum trajectory theory, developed largely in the quantum optics community to describe open quantum systems subjected to continuous monitoring, has applications in many areas of quantum physics. In this paper I present a simple model, using two-level quantum systems (q-bits), to illustrate the essential physics of quantum trajectories and how different monitoring schemes correspond to different ``unravelings'' of a mixed state master equation. I also comment briefly on the relationship of the theory to the Consistent Histories formalism and to spontaneous collapse models.

The accretion/diffusion theory for lambda Bootis stars in the light of spectroscopic data

description: Most of the current theories suggest the lambda Bootis phenomenon to originate from an interaction between the stellar surface and its local environment. In this paper, we compare the abundance pattern of the lambda Bootis stars to that of the interstellar medium and find larger deficiencies for Mg, Si, Mn and Zn than in the interstellar medium. A comparison with metal poor post-AGB stars showing evidence for circumstellar material indicates a similar physical process possibly being at work for some of the lambda Bootis stars, but not for all of them. Despite the fact that the number of spectroscopically analysed lambda Bootis stars has considerably increased in the past, a test of predicted effects with observations shows current abundance and temperature data to be still controversial.

How Did That Interactive Make You Feel? Towards a framework for evaluating the emotional and sensory experience of next generation in-gallery technology.
Creators: name: Jingyu Peng
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: This thesis explores a different way of researching and analysing in-gallery digital media. It attempts to understand how visitors feel sensorily and emotionally during the experience of interacting with in-gallery digital media, and to provide the basis of a workable framework to measure these experiences. The work is inspired by both the ‘sensory turn’ in museum studies (that has aimed to uncover a comprehensive understanding of these feelings and sensory engagement), and the arrival of new emerging formats of in-gallery digital technology (that are more likely to involve multi-sensory, highly immersive and shared experience). The thesis investigates how to measure visitors’ experience with in-gallery technologies from a brand-new perspective, beyond the traditional models of usability and learning – and into, instead, emotion and sensation.The research was conducted at the National Space Centre, Leicester (UK), testing the effectiveness of traditional tools in visitor studies and exploring the appropriateness of new evaluative methods. A series of methods were tested in three evaluative design cycles, each including a combination of interviews, questionnaires, ‘think-aloud’ methods and physiological measurement. Based on the results of measuring sensation and emotion within three different settings within the case study museum (each representing a different format of digital technology), the thesis not only offers a practical guide to museums, but proposes six core principles on approaching this new framework for evaluative design: differentiate; expand; combine; extend; contextualise; and scale.The findings of the research are intended to highlight the importance of adopting a time-based, non-verbal and non-filtered understanding and measurement of experience. Ultimately, however, the thesis identifies not only the importance of understanding in sensory and emotional terms the impact of digitally created environments on visitor experience, but also the value of using a new set of theoretical informants and theoretical foundations for digital heritage and museum studies research.

description: Eclipsing post-common envelope binaries are highly important for resolving the poorly understood, very short-lived common envelope phase. Most hot subdwarfs (sdO/Bs) are the bare He-burning cores of red giants which have lost almost all of their hydrogen envelopes. This mass loss is often triggered by common envelope interactions with close stellar or even sub-stellar companions. In the recently published catalog of eclipsing binaries in the Galactic Bulge and in the ATLAS survey, we discovered 161 new eclipsing systems showing a reflection effect by visual inspection of the light curves and using a machine-learning algorithm. The EREBOS (Eclipsing Reflection Effect Binaries from Optical Surveys) project aims at analyzing all newly discovered eclipsing binaries with reflection effect based on a spectroscopic and photometric follow up. To constrain the nature of the primary we derived the absolute magnitude and the reduced proper motion of all our targets with the help of the parallaxes and proper motions measured by the Gaia mission and compared those to the Gaia white dwarf catalogue. For a sub-set of our targets with observed spectra the nature could be derived by measuring the atmospheric parameter of the primary confirming that less than 10\% of our systems are not sdO/Bs with cool companions but white dwarfs or central stars of planetary nebula. This large sample of eclipsing hot subdwarfs with cool companions allowed us to derive a significant period distribution for hot subdwarfs with cool companions for the first time showing that the period distribution is much broader than previously thought and ideally suited to find the lowest mass companions to hot subdwarf stars. In the future several new photometric surveys will be carried out, which will increase the sample of this project even more giving the potential to test many aspects of common envelope theory and binary evolution.

description: A noteworthy physical dependence of the hysteresis losses with the axial winding misalignment of superconducting racetrack coils made with commercial \textcolor{black}{Second Generation High Temperature Superconducting (2G-HTS)} tapes is reported. A comprehensive study on the influence of the turn-to-turn misalignment factor on the local electromagnetic properties of individual turns, is presented by considering six different coil arrangements and ten amplitudes for the applied alternating transport current, $I_{a}$, together with an experimentally determined function for the magneto-angular anisotropy properties of the critical current density, $J_{c}(B,θ)$, across the superconducting tape. It has been found that for moderate to low applied currents $I_{a} \leq 0.6~I_{c0}$, with $I_{c0}$ the self-field critical current of individual tapes, the resulting hysteretic losses under extreme winding deformations can lead to an increase in the energy losses of up to $25\%$ the losses generated by a perfectly wound coil. High level meshing considerations have been applied in order to get a realistic account of the local and global electromagnetic properties of racetrack coils, .... Our findings can be used as a practical benchmark to determine the relative losses for any 2G-HTS racetrack coil application, unveiling the physical fingerprints that possible coil winding misalignments could infer.

description: Order ACANTHOTHORACI Stensiö, 1944   EMENDED DIAGNOSIS (modified from Denison 1978). — The skull is moderately long and narrow with subparallel sides and a deep embayment on the posterior margin bounded by strongly projecting paranuchals. Dermal bones may be well developed and cover the cranial roof, or they may be separated or overlain by tesserae; two pairs of paranuchals are present. The orbits are lateral or dorso-lateral, and the nostrils are dorsal, bounded anteriorly by a premedian plate and surrounded postero-mesially by a small rostral plate. The suborbital plates are short and deep, without postorbital laminae. The lateral line sensory system occupies wide, open grooves or closed canals. An exoskeletal cranio-thoracic articulation is absent. The perichondraly ossified endocranium typically is moderately long and narrow with a rostrum projecting below and anterior to the rhinocapsular ossification. Dermal bones and scales are ornamented with tubercles that are commonly stellate.
REMARKS
 Like all members of this order, Arabosteus n. gen. shows a typical sigmoid skull roof occipital border with a medial deep symmetric embayment and the posterior projection of the posterior paranuchal plate; large orbits oriented laterodorsally and a narrow interorbital wall are also special features present in most Acanthothoraci.

description: We present a reliable scheme for engineering arbitrary motional ionic states through an adaptation of the projection synthesis technique for trapped-ion phenomena. Starting from a prepared coherent motional state, the Wigner function of the desired state is thus sculpted from a Gaussian distribution. The engineering process has also been developed to take into account the errors arising from intensity fluctuations in the exciting-laser pulses required for manipulating the electronic and vibrational states of the trapped ion. To this end, a recently developed phenomenological-operator approach that allows for the influence of noise will be applied. This approach furnishes a straightforward technique to estimate the fidelity of the prepared state in the presence of errors, precluding the usual extensive ab initio calculations. The results obtained here by the phenomenological approach, to account for the effects of noise in our engineering scheme, can be directly applied to any other process involving trapped-ion phenomena.

description: We use a Sobolev with Exact Integration model to analyze the winds lines of 25 LMC O stars. The data include FUSE profiles of C III, N III, S IV, P V, S VI, and O VI and IUE or HST data for Si IV, C IV, and N V. Several of the FUSE lines are unsaturated, so meaningful optical depths (equivalently, mass loss rate times ionization fractions), as a function of wind velocity can be determined. Ratios of these quantities give the relative ionization as a function of velocity and demonstrate that, except for O VI in all stars and S VI in the later stars, the wind ionization shifts toward lower stages at higher velocity. Because O VI and S VI do not behave like the other ions, they must be produced by a different mechanism. Using mass-loss rates determined from the Vink et al. relationships, we derive mean ionization fractions. Because these are all less than one, the derived mass loss rates cannot be too small. However, the ion fractions for P V (expected to be dominant in some winds), never exceed 0.20. This implies that either the calculated mass loss rates or the assumed P abundances are too large, or the winds are strongly clumped. We examine correlations between the mean ion fractions and stellar parameters, and find two significant relationships. First, as expected, the mean ionization fraction of lower ions decreases with increasing temperature. Second, the mean ionization fraction of S VI in the latest stars and O VI in all stars increases with terminal velocity, re-affirming Cassinelli and Olson's conjecture that O VI is produced non-radiatively. Finally, we discuss peculiar aspects of three stars, BI 272, BI 208, and Sk-67 166.

description: The rapid-neutron capture process ($r$ process) is identified as the producer of about 50\% of elements heavier than iron. This process requires an astrophysical environment with an extremely high neutron flux over a short amount of time ($\sim$ seconds), creating very neutron-rich nuclei that are subsequently transformed to stable nuclei via $β^-$ decay. One key ingredient to large-scale $r$-process reaction networks is radiative neutron-capture ($n,γ$) rates, for which there exist virtually no data for extremely neutron-rich nuclei involved in the $r$ process. Due to the current status of nuclear-reaction theory and our poor understanding of basic nuclear properties such as level densities and average $γ$-decay strengths, theoretically estimated ($n,γ$) rates may vary by orders of magnitude and represent a major source of uncertainty in any nuclear-reaction network calculation of $r$-process abundances. In this review, we discuss new approaches to provide information on neutron-capture cross sections and reaction rates relevant to the $r$ process. In particular, we focus on indirect, experimental techniques to measure radiative neutron-capture rates. While direct measurements are not available at present, but could possibly be realized in the future, the indirect approaches present a first step towards constraining neutron-capture rates of importance to the $r$ process.

description: In this study, the dependence of minimum ignition energies (MIE) on ignition geometry, ignition source radius and mixture composition is investigated numerically for methane/air and isooctane/air mixtures. Methane and isooctane are both important hydrocarbon fuels, but differ strongly with respect to their Lewis numbers. Lean isooctane air mixtures have particularly large Lewis numbers. The results show that within the flammability limits, the MIE for both mixtures stays almost constant, and increases rapidly at the limits. The MIEs for both fuels are also similar within the flammability limits. Furthermore, the MIEs of isooctane/air mixtures with a small spherical ignition source increase rapidly for lean mixtures. Here the Lewis number is above unity, and thus, the flame may quench because of flame curvature effects. The observations show a distinct difference between ignition and flame propagation for iso-octane. The minimum energy required for initiating a successful flame propagation can be considerably higher than that required for initiating an ignition in the ignition volume. For iso-octane with a small spherical ignition source, this effect was observed at all equivalence ratios. For iso-octane with cylindrical ignition sources, the phenomenon appeared at lower equivalence ratios only, where the mixture’s Lewis number is large. For methane fuel, the effect was negligible. The results highlight the significance of molecular transport properties on the decision whether or not an ignitable mixture can evolve into a propagating flame.

The properties of the candidate closed string state and the wedge state are also discussed, and the possibility of the non-GMS soliton in VSFT is commented.

description: We present an analysis of a large sample of moderate resolution Keck LRIS spectra of subgiant (V \sim 17.2) and fainter stars in the Galactic globular cluster M5 (NGC 5904) with the goal of deriving C and N abundances. Star-to-star stochastic variations with significant range in both [C/Fe] and [N/Fe] are found at all luminosities extending to the bottom of the RGB at M_V \sim +3. Similar variations in CH appear to be present in the main sequence turnoff spectra. There is no sign of a change in the behavior of C and N with evolutionary stage over the full range in luminosity of the RGB and SGB. The C and N abundances appear strongly anti-correlated, as would be expected from the CN-cycle processing of stellar material. Yet the present stars are considerably fainter than the RGB bump, the point at which deep mixing is believed to set in. On this basis, while the observed abundance pattern is consistent with proton capture nucleosynthesis, we infer that the site of the reactions is likely not within the present sample, but rather in a population of more massive (2 -- 5 M(Sun)) now defunct stars. The range of variation of the N abundances is very large and the sum of C+N increases as C decreases. To reproduce this requires the incorporation not only of CN but also of ON-processed material. Furthermore, the existence of this correlation is quite difficult to reproduce with an external mechanism such as ``pollution'' with material processed in a more massive AGB star, which mechanism is fundamentally stochastic in nature. We therefore suggest that although the internal mixing hypothesis has serious flaws,new theoretical insights are needed and it should not be ruled out yet. (abridged)

description: Subfamily ZIPHIINAE Gray, 1850   TYPE GENUS. — Ziphius Cuvier, 1823.
 OTHER GENERA INCLUDED. — Choneziphius Duvernoy, 1851, Globicetus n. gen., Imocetus n. gen., Izikoziphius Bianucci, Lambert & Post, 2007, Tusciziphius Bianucci, 1997, and possibly Caviziphius Bianucci & Post, 2005.
 EMENDED DIAGNOSIS. — With the exception of Izikoziphius and Ziphius, members of the subfamily Ziphiinae differ from all other Ziphiidae in the dorsal closure of the mesorostral groove by medial sutural contact of the premaxillae extending posteriorly until the bony nares. With the exception of Choneziphius and Imocetus n. gen., they further differ from all other Ziphiidae in having very elongated nasals with the anterior tip of nasals located anterior to the premaxillary crests (ratio between length of medial suture of nasals and maximum width of nasals> 1.1). ffley further differ from all other Ziphiidae, with the exception of the clade formed by Africanacetus Bianucci, Lambert & Post, 2007, Hyperoodon, Ihlengesi Bianucci, Lambert & Post, 2007, and Mesoplodon Gervais, 1850, in having the ascending process of the premaxilla concave in lateral view, with the posterodorsal portion partly overhanging the bony nares (apart from Choneziphius planirostris (Cuvier, 1823), with bony nares still visible in dorsal view). ffley further differ from all other Ziphiidae, except Beneziphius, Messapicetus, and Ziphirostrum, in having the left premaxillary crest anterolaterally directed.

Swedish educational policy and the manifest and latent political socialization of final-year secondary students

Subjects: subject: Education and state Sweden
subject: Education Political aspects Sweden

description: Political socialization, the process of transferring political values, knowledge and orientations to new members of a society, is of fundamental importance to the future development of that society. Political socialization for a democratic society requires the nurture of individual capabilities which are consistent with an efficacious political self-image, that cannot be inculcated by indoctrination. Swedish educational policy seeks to provide for individual development in a schooling environment which is consistent with democratic values. It seeks to encourage social tolerance and a participative orientation to the political process. However, it is the individual's perceptions of his or her schooling experience and other socializing influences, including the perceived consistency between them, which determines the effects these influences have on the individual. This thesis studies whether the formation of political attitudes and self-images by a nationally representative sample of Swedish secondary school students has been influenced by their schooling experience and if so, in what ways. A key distinction is made between the manifest political socializing influence of the school courses, and the latent political socializing influence of the school environment, as it is perceived by the students. A path analysis finds that t h ere i s a moderate strength relationship between the student's perceptions of their school environment and their sense of political efficacy and government responsiveness. This establishes that the school environment has a latent political socializing influence. Detailed analysis confirms that the school not only has a · socializing influence on student's attitudes and political self-images, but that the schools are seen as a source of experience directly relevant to the students' anticipation of their relationship to the wider society and political order. The students have a generally positive view of their school environment, and the specific aspects of their schooling experience which are found to have significant associations with the students' political self-image and attitudes are given very strong positive ratings by the student respondents. Their perceptions of these aspects of their schooling experience appear to have contributed to the successful political socialization of the Swedish students, as people who see themselves as politically efficacious future citizens.

description: Searching for PD-1/PD-L1 inhibitor from medicinal plants has become a potential method to discover small molecular cancer immunotherapy drugs. Using PD-1/PD-L1 inhibitory activity assay in vitro, a bioactive fraction was obtained from the ethanol extract of Gymnadenia conopsea. A sensitive UPLC-HRMS/MS method was established for the rapid screening and identification of compositions from bioactive fraction. Based on the characteristic fragmentation patterns of standards analysis and extracted ion chromatogram (EIC) method, 46 compounds were rapidly screened and identified (including 35 succinic acid ester glycosides and 11 other compounds), among which 17 compounds were tentatively identified as new compounds.
Parametric estimation for convolutionally observed diffusion processes

description: We propose a new statistical observation scheme of diffusion processes named convolutional observation, where it is possible to deal with smoother observation than ordinary diffusion processes by considering convolution of diffusion processes and some kernel functions with respect to time parameter. We discuss the estimation and test theories for the parameter determining the smoothness of the observation, as well as the least-square-type estimation for the parameters in the diffusion coefficient and the drift one of the latent diffusion process. In addition to the theoretical discussion, we also examine the performance of the estimation and the test with computational simulation, and show an example of real data analysis for one EEG data whose observation can be regarded as smoother one than ordinary diffusion processes with statistical significance.

Unusual Phase Reversal of Superhumps in ER Ursae Majoris

Publisher: name: arXiv

description: We studied the evolution of superhumps in the peculiar SU UMa-type dwarf nova, ER UMa. Contrary to the canonical picture of the SU UMa-type superhump phenomena, the superhumps of ER UMa show an unexpected phase reversal during the very early stage (~5 d after the superoutburst maximum). We interpret that a sudden switch to so-called late superhumps occurs during the very early stage of a superoutburst. What had been believed to be (ordinary) superhumps during the superoutburst plateau of ER UMa were actually late superhumps. The implication of this discovery is briefly discussed.
