description: We study Galois actions on $2+1$D topological quantum field theories (TQFTs), characterizing their interplay with theory factorization, gauging, the structure of gapped boundaries and dualities, 0-form symmetries, 1-form symmetries, and 2-groups. In order to gain a better physical understanding of Galois actions, we prove sufficient conditions for the preservation of unitarity. We then map out the Galois orbits of various classes of unitary TQFTs. The simplest such orbits are trivial (e.g., as in various theories of physical interest like the Toric Code, Double Semion, and 3-Fermion Model), and we refer to such theories as unitary "Galois fixed point TQFTs." Starting from these fixed point theories, we study conditions for preservation of Galois invariance under gauging 0-form and 1-form symmetries (as well as under more general anyon condensation). Assuming a conjecture in the literature, we prove that all unitary Galois fixed point TQFTs can be engineered by gauging 0-form symmetries of theories built from Deligne products of certain abelian TQFTs.

description: The LAMOST spectra and $\it{Kepler}$ light curves are combined to investigate the detached eclipsing binary KIC 8098300, which shows the O'Connell effect caused by spot/facula modulation. The radial velocity (RV) measurements are derived by using the tomographic spectra disentangling technology. The mass ratio $q = K_1/K_2 = 0.812 \pm 0.007$, and the orbital semi-major axis $a\mathrm{\sin}i = 14.984 \pm 0.048\ R_\odot$ are obtained by fitting the RV curves. We optimize the binary model concerning the spot/facula activity with the code PHOEBE and obtain precise parameters of the orbit including the eccentricity $e=0.0217 \pm 0.0008$, the inclination $i=87.71\pm 0.04^\circ$, and the angle of periastron $ω=284.1\pm 0.5^\circ$. The masses and radii of the primary and secondary star are determined as $M_1=1.3467 \pm 0.0001\ M_\odot$, $R_1=1.569 \pm 0.003\ R_\odot$, and $M_2=1.0940 \pm 0.0001\ M_\odot$, $R_2=1.078 \pm 0.002\ R_\odot$, respectively. The ratio of temperatures of the two component stars is $r_{teff}=0.924 \pm 0.001$. We also obtain the periastron precession speed of $0.000024\pm 0.000001\ \mathrm{d}\ cycle^{-1}$. The residuals of out-of-eclipse are analyzed using the Auto-Correlation Function (ACF) and the Discrete Fourier Transform (DFT). The spot/facula activity is relatively weaker, but the lifetime is longer than that of most single main sequence stars in the same temperature range. The average rotation period of the spots $P_{rot}=4.32\ d$ is slightly longer than the orbital period, which may be caused by either the migration of spots/faculae along the longitude or the latitudinal differential rotation. The activity may be spot-dominated for the secondary star and facula-dominated for the primary star.

description: Проблема снижения рисков является весьма актуальной для предприятий аграрной сферы, которые ежедневно, при осуществлении предпринимательской деятельности, сталкиваются с разнообразными рисками. В современных условиях некоторые сельскохозяйственные предприятия балансируют на грани выживания и вопросы оценки рисков и управления ими становятся первоочередными. Они ведут к снижению прибыли, возникновении убытков и, в худшем случае, к банкротству предприятия. Такая ситуация делает уязвимыми предприятия АПК, особенно в нынешней нестабильной экономической ситуации. Целью данной статьи является попытка оптимизации рисков на предприятии ООО «Искра», производящем сельхозпродукцию и реализующем ее в г. Красноярске и в Красноярском крае. С этой целью были изучены: финансовое состояние предприятия, основные показатели его деятельности, основные направления рисков для предприятия, предложены мероприятия по снижению рисков. В качестве информационной основы были использованы исследования российских ученых по изучаемому вопросу, статистическая отраслевая информация, отчетные материалы исследуемой организации.

description: Collective motion by animal groups is affected by internal interactions, external constraints and the influx of information. A quantitative understanding of how these different factors give rise to different modes of collective motion is, at present, lacking.} Here, we study how ants that cooperatively transport a large food item react to an obstacle blocking their path. Combining experiments with a statistical physics model of mechanically coupled active agents, we show that the constraint induces a deterministic collective oscillatory mode that facilitates obstacle circumvention. We provide direct experimental evidence, backed by theory, that this motion is an emergent group effect that does not require any behavioral changes at the individual level. We trace these relaxation oscillations to the interplay between two forces; informed ants pull the load towards the nest while uninformed ants contribute to the motion's persistence along the tangential direction. The model's predictions that oscillations appear above a critical system size, that the group can spontaneously transition into its ordered phase, and that the system can exhibit complete rotations are all verified experimentally. We expect that similar oscillatory modes emerge in collective motion scenarios where the structure of the environment imposes conflicts between individually held information and the group's tendency for cohesiveness.

description: We present a machine-learning-based model of relativistic electron fluxes >1.8 MeV using a neural network approach in the Earth's outer radiation belt. The Outer RadIation belt Electron Neural net model for Relativistic electrons (ORIENT-R) uses only solar wind conditions and geomagnetic indices as input. For the first time, we show that the state of the outer radiation belt can be determined using only solar wind conditions and geomagnetic indices, without any initial and boundary conditions. The most important features for determining outer radiation belt dynamics are found to be AL, solar wind flow speed and density, and SYM-H indices. ORIENT-R reproduces out-of-sample relativistic electron fluxes with a correlation coefficient of 0.95 and an uncertainty factor of ~2. ORIENT-R reproduces radiation belt dynamics during an out-of-sample geomagnetic storm with good agreement to the observations. In addition, ORIENT-R was run for a completely out-of-sample period between March 2018 and October 2019 when the AL index ended and was replaced with the predicted AL index (lasp.colorado.edu/~lix). It reproduces electron fluxes with a correlation coefficient of 0.92 and an out-of-sample uncertainty factor of ~3. Furthermore, ORIENT-R captured the trend in the electron fluxes from low-earth-orbit (LEO) SAMPEX, which is a completely out-of-sample dataset both temporally and spatially. In sum, the ORIENT-R model can reproduce transport, acceleration, decay, and dropouts of the outer radiation belt anywhere from short timescales (i.e., geomagnetic storms) and very long timescales (i.e., solar cycle) variations.

description: We measure the spatial distribution and hard X-ray luminosity function of cataclysmic variables (CVs) using the INTEGRAL all-sky survey in the 17-60 keV energy band. The vast majority of the INTEGRAL detected CVs are intermediate polars with luminosities in the range 10^{32}-10^{34} erg/sec. The scale height of the Galactic disk population of CVs is found to be 130{+90}{-50} pc. The CV luminosity function measured with INTEGRAL in hard X-rays is compatible with that previously determined at lower energies (3--20 keV) using a largely independent sample of sources detected by RXTE (located at |b|>10deg as opposed to the INTEGRAL sample, strongly concentrated to the Galactic plane). The cumulative 17-60 keV luminosity density of CVs per unit stellar mass is found to be (1.3+/-0.3)x10^{27} erg/sec/Msun and is thus comparable to that of low-mass X-ray binaries in this energy band. Therefore, faint but numerous CVs are expected to provide an important contribution to the cumulative hard X-ray emission of galaxies.

description: To examine the associations between CYP2D6 and CYP3A4 polymorphisms, plasma oxycodone and metabolite concentrations, and oxycodone response (dose, pain scores, and adverse effects) in people with pain from advanced cancer. This multi-center prospective cohort study included clinical data, questionnaires (pain and adverse effects), and blood (pharmacokinetics, DNA). Negative binomial regression and logistic regression were used. Within 33 participants, there were no differences in oxycodone response between CYP2D6 intermediate/poor metabolisers compared to normal metabolisers. Higher plasma noroxycodone and noroxycodone/oxycodone concentration ratios had higher odds of uncontrolled average pain (OR 2.44 (95%CI 1.00–5.95), p = 0.05 and OR 10.48 (95%CI 1.42–77.15), p = 0.02, respectively). There was no observed benefit in CYP2D6 genotyping in oxycodone response, however monitoring noroxycodone and oxymorphone concentrations warrant further examination.

description: Despite persisting in popularity, email is still plagued with information overload, hindering the workflow of data handled by the user. Just as Semantic Web technologies promise to revolutionize the Web, we aspire to use the same technology to enhance electronic mail with useful semantics. Thus we will tackle one of the largest flaws of the email communication genre - the lack of shared expectations about the form and content of the interaction, which can be attributed to the lack of explicit semantics covering context and content of exchanged messages. Earlier research showed that email content can be captured by applying speech act theory. We will refine and extend this work to develop an email speech act ontology and outline a non-deterministic model that predicts the user¿s best course of action upon sending or receiving an email.

description: We present the ALMA detection of molecular outflowing gas in the central regions of NGC4945, one of the nearest starbursts and also one of the nearest hosts of an active galactic nucleus (AGN). We detect four outflow plumes in CO (3-2) at ~0.3" resolution that appear to correspond to molecular gas located near the edges of the known ionized outflow cone and its (unobserved) counterpart behind the disk. The fastest and brightest of these plumes has emission reaching observed line-of-sight projected velocities of over 450 km/s beyond systemic, equivalent to an estimated physical outflow velocity v>600 km/s for the fastest emission. Most of these plumes have corresponding emission in HCN or HCO+ (4-3). We discuss a kinematic model for the outflow emission where the molecular gas has the geometry of the ionized gas cone and shares the rotation velocity of the galaxy when ejected. We use this model to explain the velocities we observe, constrain the physical speed of the ejected material, and account for the fraction of outflowing gas that is not detected due to confusion with the galaxy disk. We estimate a total molecular mass outflow rate dMmol/dt~20 Msun/yr flowing through a surface within 100 pc of the disk midplane, likely driven by a combination of the central starburst and AGN.

description: We study conical square function estimates for Banach-valued functions, and introduce a vector-valued analogue of the Coifman-Meyer-Stein tent spaces. Following recent work of Auscher-McIntosh-Russ, the tent spaces in turn are used to construct a scale of vector-valued Hardy spaces associated with a given bisectorial operator (A) with certain off-diagonal bounds, such that (A) always has a bounded (H^{\infty})-functional calculus on these spaces. This provides a new way of proving functional calculus of (A) on the Bochner spaces (L^p(\R^n;X)) by checking appropriate conical square function estimates, and also a conical analogue of Bourgain's extension of the Littlewood-Paley theory to the UMD-valued context. Even when (X=\C), our approach gives refined (p)-dependent versions of known results.

Pressure and Ionization Balances in the Circum-Heliospheric Interstellar Medium and the Local Bubble
Creators: name: Jenkins, Edward B.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A disconcerting mismatch of thermal pressures for two media in contact with each other, (1) the warm, Circum-heliospheric Interstellar Medium (CHISM) and (2) the very hot material within a much larger region called the Local Bubble (LB), has troubled astronomers for over two decades. A possible resolution of this problem, at least in part, now seems possible. We now understand that earlier estimates for the average electron density in the very hot LB plasma were inflated by an unrecognized foreground contamination to the low energy diffuse X-ray background measurements. This foreground illumination arises from photons emitted by charge exchange reactions between solar wind ions and neutral atoms from the interstellar medium that enter into the heliosphere. However, with the resolution of this problem comes a new one. The high ionization fraction of helium in the CHISM, relative to that of hydrogen, could be understood in terms of the effects from a strong flux of EUV and X-ray radiation coming from both the Local Bubble and a conductive interface around the CHISM. A revision of this interpretation may now be in order, now that the photoionization rate from radiation emitted by hot gas the Local Bubble is lower than previously assumed.

description: Defined as the intentional or unintentional spread of false information (K et al., 2019) through context and/or content manipulation, fake news has become one of the most serious problems associated with online information (Waldrop, 2017). Consequently, it comes as no surprise that Fake News Detection has become one of the major foci of various fields of machine learning and while machine learning models have allowed individuals and companies to automate decision-based processes that were once thought to be only doable by humans, it is no secret that the real-life applications of such models are not viable without the existence of an adequate training dataset. In this paper we describe the Veritas Annotator, a web application for manually identifying the origin of a rumour. These rumours, often referred as claims, were previously checked for validity by Fact-Checking Agencies.

description: A Raman study of a back gated bilayer graphene sample is presented. The changes in the Fermi level induced by charge transfer splits the Raman G-band, hardening its higher component and softening the lower one. These two components are associated with the symmetric (S) and anti-symmetric vibration (AS) of the atoms in the two layers, the later one becoming Raman active due to inversion symmetry breaking. The phonon hardening and softening are explained by considering the selective coupling of the S and AS phonons with interband and intraband electron-hole pairs.

description: Gegenstand der vorliegenden Masterarbeit ist die Realisierung eines EXIT-Puzzles mit integrierten AR- und VR-Elementen. Im Kontext der Wissensvermittlung im Fachgebiet Mathematik angewandt, wirken sowohl die Verwendung des Gesellschaftsspiels als auch der Gebrauch moderner Techniken motivierend auf die Schülerinnen und Schüler. Auf die theoretischen Erkenntnisse, welche mit Hilfe einer umfangreichen Literaturrecherche gesammelt wurden, baut die Analyse verwandter Arbeiten auf. Anhand von 11 semi-strukturierten Benutzerinterviews, konnten Information über die Zielgruppe, den Nutzungskontext und eventuelle Problempunkte des geplanten Puzzles zusammengetragen werden. Auf Grundlage dieses Wissens wurde ein Katalog der wichtigsten Anforderungen und Schwerpunkte aufgestellt. In der Konzeptionsphase wurde dieser Anforderungskatalog als Basis für die Planung des EXIT-Puzzles verwendet, welche anschließend prototypisch umgesetzt wurde. Dieser Prototyp wurde abschließend einer Evaluation anhand von zehn Benutzertests unterzogen, welche einerseits die Gebrauchstauglichkeit des Puzzles erfassen und andererseits Anregungen zur weiteren Verbesserung festhalten sollten. Diese abschließende Evaluation konnte sowohl die Gebrauchstauglichkeit des Puzzles bestätigen als auch Hinweise darauf liefern, dass die Applikation beim Anwenden und Verstehen des Unterrichtsstoffes unterstützend wirkt und unter gewissen Bedingungen für den Einsatz im Mathematikunterricht geeignet wäre.
description: The subject of this master thesis is the realization of an exit puzzle with integrated elements of AR and VR. Applied in the context of knowledge transfer in the subject area of mathematics, both the use of a board game and modern techniques have a motivating effect on the student body. The analysis of related work is based on theoretical insights, which were collected by literature research. On the foundation of eleven semi-structured interviews, information about the target group, the context of use, and possible problems of the scheduled puzzle could be gathered. Based on this knowledge, a catalog of the main requirements and priorities was made. In the conception phase, this accumulation used to be the groundwork for the development of the exit puzzle, which was implemented prototypically afterward. Finally, this prototype has undergone an evaluation with ten user trials, which on the one side should capture the usability of the puzzle and on the other side should record suggestions for further improvements. This concluding evaluation could confirm the usability of the puzzle as well as provide indications that the application has a supporting effect on the usage and understanding of the subject matters. Furthermore, the evaluation has shown that the application under certain conditions is suitable for use in mathematics class.
Fracture toughness of a carbon fibre-epoxy composite material
Creators: name: Radford, Donald W.
Publisher: name: University of British Columbia
Year: 2010

description: Testing has been undertaken to study the applicability of linear elastic fracture mechanics to a carbon fibre-epoxy laminate system. Hercules AS/3501-6 carbon fibre-epoxy prepreg was used to produce laminates which were subsequently cut into specimens of various geometries, sizes, and thicknesses. Plane strain equations were used to calculate values of fracture toughness as the notch proportion, specimen size, geometry, and thickness were varied. The results indicate that the toughness is independent of specimen geometry, size, and thickness; however, the toughness is seen to fall dramatically at increasing values of notch proportion. To substantiate these trends compliance calibrations were carried out for the various specimens. The trends arrived at through the compliance calibration show close agreement with those found using the plane strain method. Together these results indicate that for a narrow range of notch proportions (a/W = 0.2 to 0.5) linear elastic fracture mechanics can be applied, yielding a value of fracture toughness which behaves as a material constant comparable to K[sub 1C].

description: The temperature inversion symmetry $R\to \frac{1}{T}$ is studied for the finite temperature effective potential of the N=1, $d=5$, supersymmetric $SU(3)_{c}{\times}SU(3)_{w}$ model, on the orbifold $S^{1}/Z_{2}$. For the value of the Wilson line parameter $α=1$ ($SU(2)_{L}$ breaks to a $U'(1)$), it is found that the effective potential contains a symmetric part and an anti-symmetric part under $ξ\to \frac{1}ξ$, with, $ξ=RT$. When $α=0$ (for which, $SU(2)_{L}$ remains unbroken) it is found that the only contribution to the effective potential that spoils the temperature inversion symmetry comes from the fermions in the fundamental representation of the gauge group, with $(+,+)$ or $(-,-)$, $Z_{2}$ parities. This is interesting since it implies that the bulk effective potential corresponding to models with orbifold fixed point localized fundamental fermions (and with no bulk fundamental fermions) has the temperature inversion symmetry.

description: Bad smells have been defined to describe potential problems in code, possibly pointing out refactoring opportunities. Several empirical studies have highlighted that smells have a negative impact on comprehension and maintainability. Consequently, several approaches have been proposed to detect and restructure them. However, studies on the inter-relationship of occurrence of different types of smells in source code are still lacking, especially those focused on the quantification of this inter-relationship. In this work, we aim at understand and quantify the possible the inter-relation of smells Large Class - LC, Complex Class - CC and Duplicate Code - DC. In particular, we investigate patterns of LC and CC regarding the presence or absence of duplicate code. We conduct a quantitative study on five open source projects, and also a qualitative analysis to measure and understand the association of specific smells. As one of the main results, we highlight that there are "occurrence patterns" among these smells, for example: either in Complex Class or in the co-occurrence of Large Class and Complex Class, clones tend to be more prevalent in highly complex classes than less complex classes. The found patterns could be used to improve the performance of detection tools or even help in refactoring tasks.

description: Calvera (1RXS J141256.0+792204) is an isolated neutron star detected only through its thermal X-ray emission. Its location at high Galactic latitude ($b=+37^\circ$) is unusual if Calvera is a relatively young pulsar, as suggested by its spin period (59 ms) and period derivative ($3.2 \times 10^{-15}$ Hz s$^{-1}$). Using the Neutron Star Interior Composition Explorer (NICER), we obtained a phase-connected timing solution spanning four years which allowed us to measure the second derivative of the frequency $\ddotν= -2.5 \times 10^{-23}$ Hz s$^{-2}$ and to reveal timing noise consistent with that of normal radio pulsars. A magnetized hydrogen atmosphere model, covering the entire star surface, provides a good description of the phase-resolved spectra and energy-dependent pulsed fraction. However, we find that a temperature map more anisotropic than that produced by a dipole field is required, with a hotter zone concentrated towards the poles. By adding two small polar caps, we find that the surface effective temperature and that of the caps are ~0.1 and ~0.36 keV, respectively. The inferred distance is ~3.3 kpc. We confirm the presence of an absorption line at 0.7 keV associated to the emission from the whole star surface, difficult to interpret as a cyclotron feature and more likely originating from atomic transitions. We searched for pulsed $γ$-ray emission by folding seven years of Fermi-LAT data using the X-ray ephemeris, but no evidence for pulsations was found. Our results favour the hypothesis that Calvera is a normal rotation-powered pulsar, with the only peculiarity of being born at a large height above the Galactic disk.

description: With the emergence of the SemanticWeb, encapsulating annotations and metadata into scientific documents became a widely used practice. But in the same time, we observed the lack of well established standard tools supporting this process. There exist a large number of tools used to create a posteriori an- notations for web pages and scientific documents, with the remark that none of them can be considered a de facto standard. When it comes to a priori annotations the number decreases significantly. Our paper describes the first steps taken towards a comprehensive and elaborated approach for sup- porting a priori annotation of LATEX documents with the goal of transforming the final result into a se- mantic document which could be used for different purposes.

description: This work presents a new recursive robust filtering approach for feature-based 3D registration. Unlike the common state-of-the-art alignment algorithms, the proposed method has four advantages that have not yet occurred altogether in any previous solution. For instance, it is able to deal with inherent noise contaminating sensory data; it is robust to uncertainties caused by noisy feature localisation; it also combines the advantages of both (Formula presented.) and (Formula presented.) norms for a higher performance and a more prospective prevention of local minima. The result is an accurate and stable rigid body transformation. The latter enables a thorough control over the convergence regarding the alignment as well as a correct assessment of the quality of registration. The mathematical rationale behind the proposed approach is explained, and the results are validated on physical and synthetic data.

description: Gas at high Galactic latitude is a relatively little-noticed component of the interstellar medium. In an effort to address this, forty-one Planck Galactic Cold Clumps at high Galactic latitude (HGal; $|b|>25^{\circ}$) were observed in $^{12}$CO, $^{13}$CO and C$^{18}$O J=1-0 lines, using the Purple Mountain Observatory 13.7-m telescope. $^{12}$CO (1-0) and $^{13}$CO (1-0) emission was detected in all clumps while C$^{18}$O (1-0) emission was only seen in sixteen clumps. The highest and average latitudes are $71.4^{\circ}$ and $37.8^{\circ}$, respectively. Fifty-one velocity components were obtained and then each was identified as a single clump. Thirty-three clumps were further mapped at 1$^\prime$ resolution and 54 dense cores were extracted. Among dense cores, the average excitation temperature $T_{\mathrm{ex}}$ of $^{12}$CO is 10.3 K. The average line widths of thermal and non-thermal velocity dispersions are $0.19$ km s$^{-1}$ and $0.46$ km s$^{-1}$ respectively, suggesting that these cores are dominated by turbulence. Distances of the HGal clumps given by Gaia dust reddening are about $120-360$ pc. The ratio of $X_{13}$/$X_{18}$ is significantly higher than that in the solar neighbourhood, implying that HGal gas has a different star formation history compared to the gas in the Galactic disk. HGal cores with sizes from $0.01-0.1$ pc show no notable Larson's relation and the turbulence remains supersonic down to a scale of slightly below $0.1$ pc. None of the HGal cores which bear masses from 0.01-1 $M_{\odot}$ are gravitationally bound and all appear to be confined by outer pressure.

description: В современных условиях птицефабрикам необходимо развиваться в улучшении технологий производства, маркетинга и повышения своего имиджа. Потребители выбирают качественный товар, все чаще интересуясь процессом производства и открытой информации о сертификации. Для предприятий птицеводство является выгодным, ведь птицы скороспелы и отличаются быстрым воспроизводством. В современных условиях деятельность, которую производят птицефабрики, является очень актуальной и востребованной на рынке продуктов питания. Благодаря технологиям производства, научным достижениям и поддержки государство птицеводство становится достаточно доступным видом деятельности для предприятий. Для правильного выращивания здорового паводка на убой должны соблюдаться правильные меры освещения, кормления, ухода. Эта тема особенно актуально в развитых промышленных странах Европы, так как граждане имеют высокую гражданскую позицию по вопросам правильного содержания животных в период их жизнедеятельности.

description: The conjugacy search problem in a group $G$ is the problem of recovering an $x \in G$ from given $g \in G$ and $h=x^{-1}gx$. The alleged computational hardness of this problem in some groups was used in several recently suggested public key exchange protocols, including the one due to Anshel, Anshel, and Goldfeld, and the one due to Ko, Lee et al. Sibert, Dehornoy, and Girault used this problem in their authentication scheme, which was inspired by the Fiat-Shamir scheme involving repeating several times a three-pass challenge-response step. In this paper, we offer an authentication scheme whose security is based on the apparent hardness of the twisted conjugacy search problem, which is: given a pair of endomorphisms (i.e., homomorphisms into itself) phi, ψof a group G and a pair of elements w, t \in G, find an element s \in G such that t = ψ(s^{-1}) w ϕ(s) provided at least one such s exists. This problem appears to be very non-trivial even for free groups. We offer here another platform, namely, the semigroup of all 2x2 matrices over truncated one-variable polynomials over F_2, the field of two elements, with transposition used instead of inversion in the equality above.
