Macro-glial specialization in the brain
Creators: name: Thompson, Sharleen Grace
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the evidence for glial cell specialization. It starts with an historical description of the development of ideas about glial cells, demonstrating how each technological advance allowed an increase in understanding of various morphologically different types of glial cells and how each technique provided more evidence for glial heterogeneity. The most spectacular recent development is the increasing evidence for biochemical heterogeneity in cells in vivo, in different cell lines and in primary cultures from various regions. These biochemical differences have been found both among cells that are morpholgically similar and between different cell types. The results of three experiments which provide direct or indirect evidence for glial cell heterogeneity are presented. The first experiment is an anatomical analysis of the cellular localization of hemosiderin in rat brain. The results show primary localization to oligodendrocytes but not all oligodendrocytes as there are distinct regional differences in both density and numbers of oligodendrocytes staining. In the second experiment, an alternate route of glutamate formation from proline or ornithine via 1-pyrroline dehydrogenase is demonstrated and shown to be present in only a small subset of glial cells and not in other cell types. In the third experiment the glial heterogeneity concept is used to provide an alternate interpretation of all data on biochemical effects of thiamine deficiency in rat brain. The conclusion summarizes the contribution of the experiments to the already strong evidence for glial heterogeneity and suggests ways that assumptions of glial heterogeneity rather than homogeneity could affect research the neurosciences.

description: We present radio observations and optical spectroscopy of the giant low surface brightness (LSB) galaxy PGC 045080 (or 1300+0144). PGC 045080 is a moderately distant galaxy having a highly inclined optical disk and massive HI gas content. Radio continuum observations of the galaxy were carried out at 320 MHz, 610 MHz and 1.4 GHz. Continuum emission was detected and mapped in the galaxy. The emission appears extended over the inner disk at all three frequencies. At 1.4 GHz and 610 MHz it appears to have two distinct lobes. We also did optical spectroscopy of the galaxy nucleus; the spectrum did not show any strong emission lines associated with AGN activity but the presence of a weak AGN cannot be ruled out. Furthermore, comparison of the H$α$ flux and radio continuum at 1.4 GHz suggests that a significant fraction of the emission is non-thermal in nature. Hence we conclude that a weak or hidden AGN may be present in PGC 045080. The extended radio emission represents lobes/jets from the AGN. These observations show that although LSB galaxies are metal poor and have very little star formation, their centers can host significant AGN activity. We also mapped the HI gas disk and velocity field in PGC 045080. The HI disk extends well beyond the optical disk and appears warped. In the HI intensity maps, the disk appears distinctly lopsided. The velocity field is disturbed on the lopsided side of the disk but is fairly uniform in the other half. We derived the HI rotation curve for the galaxy from the velocity field. The rotation curve has a flat rotation speed of ~ 190 km/s.

description: The partially-averaged Navier-Stokes (PANS) equations are used to predict the variable-density Rayleigh-Taylor (RT) flow at Atwood number 0.5 and maximum Reynolds number $500$. This is a prototypical problem of material mixing featuring laminar, transitional, and turbulent flow, instabilities and coherent structures, density fluctuations, and production of turbulence kinetic energy by both shear and buoyancy mechanisms. These features pose numerous challenges to modeling and simulation, making the RT flow ideal to develop the validation space of the recently proposed PANS BHR-LEVM closure. The numerical simulations are conducted at different levels of physical resolution and test three approaches to set the parameters $f_ϕ$ defining the range of physically resolved scales. The computations demonstrate the efficiency (accuracy vs. cost) of the PANS model predicting the spatio-temporal development of the RT flow. Results comparable to large-eddy simulations and direct numerical simulations are obtained, at significantly lower physical resolution without the limitations of the Reynolds-averaged Navier-Stokes equations in these transitional flows. The data also illustrate the importance of appropriate selection of the physical resolution and the resolved fraction of each dependent quantity $ϕ$ of the turbulent closure, $f_ϕ$. These two aspects determine the ability of the model to resolve the flow phenomena not amenable to modeling by the closure and, as such, the computations' fidelity.

description: We study the morphology of the stellar periphery of the Magellanic Clouds in search of substructure using near-infrared imaging data from the VISTA Hemisphere Survey (VHS). Based on the selection of different stellar populations using the ($J-K_\mathrm{s}$, $K_\mathrm{s}$) colour-magnitude diagram, we confirm the presence of substructures related to the interaction history of the Clouds and find new substructures on the easter side of the LMC disc which may be owing to the influence of the Milky Way, and on the northern side of the SMC, which is probably associated to the ellipsoidal structure of the galaxy. We also study the luminosity function of red clump stars in the SMC and confirm the presence of a bi-modal distance distribution, in the form of a foreground population. We find that this bi-modality is still detectable in the eastern regions of the galaxy out to a 10 deg distance from its centre. Additionally, a background structure is detected in the North between 7 and 10 deg from the centre which might belong to the Counter Bridge, and a foreground structure is detected in the South between 6 and 8 deg from the centre which might be linked to the Old Bridge.

description: Data quality monitoring is critical to all experiments impacting the quality of any physics results. Traditionally, this is done through an alarm system, which detects low level faults, leaving higher level monitoring to human crews. Artificial Intelligence is beginning to find its way into scientific applications, but comes with difficulties, relying on the acquisition of new skill sets, either through education or acquisition, in data science. This paper will discuss the development and deployment of the Hydra monitoring system in production at Gluex. It will show how "off-the-shelf" technologies can be rapidly developed, as well as discuss what sociological hurdles must be overcome to successfully deploy such a system. Early results from production running of Hydra will also be shared as well as a future outlook for development of Hydra.

description: Self-gravitating astronomical objects often show a central plateau in the density profile (core) whose physical origin is hotly debated. Cores are theoretically expected in N-body systems of maximum entropy, however, they are not present in the canonical N-body numerical simulations of cold dark matter (CDM). Our work shows that despite this apparent contradiction between theory and numerical simulations, they are fully consistent. Simply put, cores are characteristic of systems in thermodynamic equilibrium, but thermalizing collisions are purposely suppressed in CDM simulations. When collisions are allowed, N-body numerical simulations develop cored density profiles, in perfect agreement with the theoretical expectation. We compare theory and two types of numerical simulations: (1) when DM particles are self-interacting (SIDM) with enough cross-section, then the effective two-body relaxation timescale becomes shorter than the Hubble time resulting in cored DM haloes. The haloes thus obtained, with masses from dwarf galaxies to galaxy clusters, collapse to a single shape after normalization, and this shape agrees with the polytropic density profile theoretically expected. (2) The inner radii in canonical N-body numerical simulations are always discarded because the use of finite-mass DM particles artificially increases the two-body collision rate. We show that the discarded radii develop cores that are larger than the employed numerical softening and have polytropic shapes independently of halo mass. Our work suggests that the presence of cores in simulated (or observed) density profiles can used as evidence for systems in thermodynamic equilibrium.

description: To evaluate whether small farmers are willing to accept the policy of sustainable use of cultivated land such as green manure planting, we analyze the payment preference and the source of heterogeneity of small farmer’s environmental attributes of leguminous green manure. A choice experiment method is conducted to learn about small farmer’s preference toward green manure. The results suggest that small farmers with planting confidence are willing to pay for different environmental attributes of leguminous green manure. Among them, the willingness to pay (WTP) for the quality and fertility of cultivated land is the highest, and the WTP for air quality is the lowest. Small farmers who do not have confidence in planting are only willing to pay for attribute of natural disaster days. We identify key factors that might influence small farmer’s payment preference, including gender, age, education level, degree of part-time employment, and the trend perception of environmental change.

description: A new family of models of flavour chiral symmetry breaking is proposed. The models are based on the embedding of a stack of D7-branes and a stack of anti D7-branes in the conifold background. This family of gravity models is dual to a field theory with spontaneous breaking of conformal invariance and chiral flavour symmetry. We identify the corresponding Goldstone bosons and compute the spectra of massive scalar and vector mesons. The dual quiver gauge theory is also discussed. We further analyse a model where chiral symmetry is not broken.

description: We use a series of high-resolution simulations of a `Milky-Way' halo coupled to semi-analytic methods to study the formation of our own Galaxy and of its stellar halo. The physical properties of our model Milky Way, as well as the age and metallicity distribution of stars in the different components, are in relatively good agreement with observational measurements. Assuming that the stellar halo builds up from the cores of the satellite galaxies that merged with the Milky Way over its life-time, we are able to study the physical and structural properties of this component. In agreement with previous work, we find that the largest contribution to the stellar halo should come from a few relatively massive (10^8 - 10^10 Msun) satellites, accreted at early times. Our "stellar halo" does not exhibit any clear metallicity gradient, but higher metallicity stars are more centrally concentrated than stars of lower abundance. This indicates that the probability of observing low-metallicity halo stars increases with distance from the Galactic centre. We find that the proposed "dual" nature of the Galactic stellar halo can be explained in our model as a result of a mass-metallicity relation imprinted in the building blocks of this component.

description: В статье анализируются феномены богатства и бедности в сочинениях апостольских отцов ранних апологетов. Основное внимание уделено специфике христианкой проповеди, которая позволяет выделить различные подходы к материальному состоянию верующего. В статье высказывается предположение, что эти различия продиктованы различиями в христианской антропологии в разных регионах Средиземноморья, и в зависимости от того, в какой степени человек физичен и принадлежит материальному миру, определяется влияние на него материальных благ. В свою очередь взгляд на человека у христианских авторов формируется исходя из их философских предпочтений, что, безусловно, не позволяет распространять их представления на всю региональную общину, но позволяет говорить о некоей господствующей тенденции. По мнению автора статьи, на этом основании можно говорить об изначальной разнице в отношении к богатству и бедности в западной и восточной частях христианского мира.
description: The article analyzes the phenomena of wealth and poverty in the writings of Apostolic Fathers and early apologists. The main attention is paid to the specifics of the Christian sermon, with different approaches to the material condition of the believer being highlighted. As suggested, these differences were caused by the specifics of Christian anthropology in different regions of the Mediterranean. Depending on the extent to which a person was seen as physical and a part of the material world, the influence of wealth on him was determined. In turn, the idea of a man was formed on the basis of the philosophical preferences of the Christian authors. This does not allow to extended their ideas on the entire regional community, but helps to understand some dominant trends. According to the author, the initial difference in attitudes towards wealth and poverty in the western and eastern parts of the Christian world should be admitted.

description: В статье мы обращаемся к тексту раннехристианского писателя Оригена «Против Цельса» с целью выявить характер употребления терминов «богатство» и «варварство» в рамках формирующегося христианского дискурса, а так же проанализировать то, как данные социальные категории использовались в первом из дошедших до нас антихристианском сочинении. «Правдивое слово» Цельса, написанное около 177 г., дошло до нас лишь обрывочно через посредство ответной работы Оригена.  Особое внимание мы уделим противопоставлению указанных понятий, которое стало возможно из-за добавления к ним контекста – в случае христианского автора позитивной коннотации, а в словах языческого критика отрицательной. У Оригена имеется особая стратегия противопоставлений привычных греко-римских идей и мировоззренческих установок между собой, а также и с текстом священных для него писаний.
description: In the article we turn to the text of the early Christian writer Origen «Against Celsus» in order to identify the nature of the use of the terms «wealth» and «barbarism» in the framework of the emerging Christian discourse, as well as to analyze how these social categories were used in the first anti-Christian writing that has come down to us. «The True Word» of Celsus, written about 177, has come down to us only in fragments through the medium of Origen's response work. We will pay special attention to the opposition of these concepts, which became possible due to the addition of context to them - in the case of a Christian author, a positive connotation, and in the words of a pagan critic, a negative one. Origen has a special strategy of contrasting the usual Greco-Roman ideas and worldviews with each other, as well as with the text of scriptures which were sacred to him.

description: Large companies have to deal with complex business processes involving a multitude
of tasks and participants. Such business processes are visualized in process models
by using modeling languages. In case of procedural processes, imperative modeling
languages are used like for example the Business Process Model and Notation (BPMN)
which is the recent standard for business process modeling. Process models can
contain hundreds of modeling elements to represent all details of large business processes.
Furthermore, process models are displayed to customers and domain experts
having only limited process modeling knowledge in the same way as modelled by the
process designer. Participants can hardly get the workflows of the underlying process
or extract the parts that are necessary for them, i.e. they are somehow involved in.
For this reason, personalized process views on the process model are needed. This
means that users need to be able to decide which parts of the process model are
contained in their view and how they are visualized by determining corresponding
parameters.
In this work we present an approach to construct different types of process views
based on BPMN models. Therefore we adapt parameterizable view operations
from related work for their application to BPMN models. Respective operations
enable users to reduce or aggregate process information in their desired way. We
extend these techniques by view-building mechanisms which enable perspectives on
the process model in different representation forms. Furthermore, we provide an
implementation based on the modeling tool BPMN.io. The evaluation of our implementation
with artificial and real-life models confirms their correct functionality and
flexible utilization. The performance tests with a large number of generated process
models show that the implemented aggregation procedure can even be used for
process models consisting of more than 500 elements. Ideas for further extensions
concerning the conceptual approach as well as the implementation are suggested.

description: {The selection of AGB C and M stars from NIR colours has been done in recent years using adjustable criteria that are in needs of standardization if one wants to compare, in a coherent manner, properties of various populations.} We intend to assess the NIR colour technique to identify C and M stars. We compare the NIR colours of several C stars previously identified from spectroscopy or narrow band techniques in WLM, IC 10 and NGC 6822. We demonstrate that very few M stars have $(J-K)_0 > 1.4$ but a non negligible number of C stars are bluer than this limit. Thus, counts of M and C stars based on such limit do not produce pure samples. C/M ratios determined from NIR colours must be regarded as underestimates mainly because the M numbers include many warm C stars and also K stars if no blue limit is considered.

description: We study the dynamics of strongly correlated one-dimensional Bose gases in a combined harmonic and optical lattice potential subjected to sudden displacement of the confining potential. Using the time-evolving block decimation method, we perform a first-principles quantum many-body simulation of the experiment of Fertig {\it et al.} [Phys. Rev. Lett. {\bf 94}, 120403 (2005)] across different values of the lattice depth ranging from the superfluid to the Mott insulator regimes. We find good quantitative agreement with this experiment: the damping of the dipole oscillations is significant even for shallow lattices, and the motion becomes overdamped with increasing lattice depth as observed. We show that the transition to overdamping is attributed to the decay of superfluid flow accelerated by quantum fluctuations, which occurs well before the emergence of Mott insulator domains.

description: Big data is no more "all just hype" but widely applied in nearly all aspects of our business, governments, and organizations with the technology stack of AI. Its influences are far beyond a simple technique innovation but involves all rears in the world. This chapter will first have historical review of big data; followed by discussion of characteristics of big data, i.e. from the 3V's to up 10V's of big data. The chapter then introduces technology stacks for an or-ganization to build a big data application, from infrastruc-ture/platform/ecosystem to constructional units and components. Finally, we provide some big data online resources for reference.

description: We study macroscopic quantum tunneling (MQT) in c-axis twist Josephson junctions made of high-T_c superconductors in order to clarify the influence of the anisotropic order parameter symmetry (OPS) on MQT. The dependence of the MQT rate on the twist angle $γ$ about the c-axis is calculated by using the functional integral and the bounce method. Due to the d-wave OPS, the $γ$ dependence of standard deviation of the switching current distribution and the crossover temperature from thermal activation to MQT are found to be given by $\cos2γ$ and $\sqrt{\cos2γ}$, respectively. We also show that a dissipative effect resulting from the nodal quasiparticle excitation on MQT is negligibly small, which is consistent with recent MQT experiments using Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8 + δ}$ intrinsic junctions. These results indicate that MQT in c-axis twist junctions becomes a useful experimental tool for testing the OPS of high-T_c materials at low temperature, and suggest high potential of such junctions for qubit applications.

description: The interplay between quadrupole and octupole degrees of freedom is discussed in a series of neutron-rich actinides and superheavy nuclei with $92 \le$ Z $\le 110$ and $186 \le$ N $\le 202$. In addition to the static Hartree-Fock-Bogoliubov approach, dynamical beyond-mean-field correlations are taken into account via both parity restoration and symmetry-conserving Generator Coordinate Method calculations based on the Gogny-D1M energy density functional. Physical properties such as correlation energies, negative-parity excitation energies as well as reduced transition probabilities $B(E1)$ and $B(E3)$ are discussed in detail. It is shown that, for the studied nuclei, the quadrupole-octupole coupling is weak and to a large extent the properties of negative parity states can be reasonably well described in terms of the octupole degree of freedom alone.

description: Fortified fruit juice represents a growing segment in the otherwise contracting juice industry. Health concerns and changing food policy have driven US consumers to demand fruit juice fortified with micronutrients. Fruit-juice manufacturers have responded by expanding their portfolio to include juice products fortified with vitamins and minerals. This study is the first to analyze determinants of US household expenditures on fortified fruit juice. Collectively, results indicate fruit-juice fortification is a viable strategy for improving public health among demographic subgroups that are disproportionately vulnerable or at-risk for nutrient deficiencies. Findings suggest that fruit-juice manufacturers’ fortification efforts are improving the nutritional intake of toddlers and children but are less effective at reaching other demographic subgroups (rural and minority-headed households) with high nutrient-deficiency incidence. Manufacturers should consider employing targeted marketing and outreach efforts to maximize improvement in dietary quality among fruit-juice consumers.

The study of the physics underlying the coincidence between the GZK energy and the clustering energy of UHECR ions favors a composition of > 60 EeV UHECRs in CNO group nucleons. This has interesting implications for the sources of UHECRs. We also comment on the Auger analysis.

Krankheitsbekaempfung bei Ackerbohnen
Creators: name: Roth, Philipp
Publisher: name: Zenodo
Year: 2021

description: Pilzkrankheiten sind im Ackerbohnenanbau in Mitteleuropa einer der Gründe für die relativ großen Ertragsschwankungen dieser Kultur. Insbesondere der Ackerbohnenrost (Uromyces viciae-fabae) sowie die Schokoladenfleckenkrankheit (Botrytis fabae) können teils deutliche Ertragsminderungen hervorrufen. Beide Krankheiten verursachen durch den Befall des Blattapparates der Ackerbohne eine Verringerung der photosynthetisch aktiven Pflanzenoberfläche, und, je nach Befallsstärke, auch ein früheres Absterben der Gesamtpflanze. Daraus resultiert letzten Endes eine reduzierte Bildung von Assimilaten, welche wiederum für den Aufbau der Samenkörner, und somit der Generierung von Ernteertrag, fehlen.
Influence of cutting block size on the efficiency of several 3-P sampling variations as compared to point sampling

description: For 3-P sampling, an ocular prediction of volume must be made on every tree in a cutting block, which casts doubt on its efficiency in larger blocks. However, it has three main advantages over the standard BCMF prism cruising procedures. First, individual trees are the sampling units, not plots of trees, so greater precision may result for a given sample size, second, no height/dbh regressions need be calculated, third, it potentially avoids volume equation biases when it is used in conjunction with dendrometry. A simpler sampling procedure, ratio estimation, differing from 3-P in that sample trees are selected with equal probability, may also prove advantageous. A study was conducted in the UBC research forest in which several blocks were cruised using all three of these methods. A volume equation, the wide-scale relaskop, and the Barr and Stroud dendrometer type FP-12 were tested as tree measurement methods for use with 3-P and ratio estimation. Results indicate that 3-P is more efficient than point sampling in blocks ranging in size up to between 5 and 14 hectares, depending on the tree measurement method chosen and the height/dbh regressions deemed necessary for use in the standard cruise. Ratio estimation is more efficient than point sampling in block sizes ranging up to 14 hectares depending on the same factors as 3-P.

description: We study the spin-orbit splitting ($ls$-splitting) for the proton d-orbits in 23F in the Hartree-Fock framework with the tensor force in the exchange channel. 23F has one more proton around the neutron-rich nucleus 22O. A recent experiment indicates that the ls-splitting for the proton d-orbits in 23F is reduced from that in 17F. Our calculation shows that the ls-splitting in 23F becomes smaller by about a few MeV due to the tensor force. This effect comes from the interaction between the valence proton and the occupied neutrons in the 0d5/2 orbit through the tensor force and makes the ls-splitting in 23F close to the experimental data.

description: [Context] Water fountain stars are very young post-AGB stars with high velocity water maser jets. They are the best objects to study the onset of bipolar jets from evolved stars due to their young dynamical ages. [Methods] We use the Arizona Radio Observatory 10m telescope to observe the CO J=2-1 line and compare the line parameters with that of masers. [Results] We report the detection of 12CO and 13COJ=2-1 lines from IRAS 16342-3814. The inferred 12CO mass loss rate is an order of magnitude lower than the infrared and OH mass loss rates, indicating a very cold and thick O-rich circumstellar envelope around the star. We also find a 12CO expansion velocity of Vexp = 46 +- 1 km/s that is too high for an AGB wind and confirm the systemic velocity of 44 +- 1 km/s. In addition we measure a very low 12CO/13CO line ratio of 1.7. [Conclusions] The first detection of CO lines has provided a new way to investigate the water fountain stars. Given the high expansion velocity of the CO gas and its relation to maser velocities, we infer that the CO emission region is co-located with the OH mainline masers in the warm base of the optical bipolar lobes, while the high velocity OH1612MHz and H2O masers are located in the side walls and at the farthest ends of the bipolar lobes, respectively. Further observations are highly desired to understand the very low 12CO/13CO line ratio.

Year: 2021

description: Die vorliegende Arbeit bearbeitet das Themenfeld Führungsverhalten und Unternehmenskultur im Kontext von BGM und psychischer Gesundheit. Anhand von Leitfadeninterviews mit BGM-Fachpersonen aus fünf Friendly Works Space zertifizierten Unternehmen aus dem Gesundheitssektor in der Schweiz sowie zwei Experten wird erörtert, inwiefern Führungsverhalten und Unternehmenskultur die psychische Gesundheit der Mitarbeitenden beeinflusst und welche Bestandteile des BGMs eine zentrale Rolle spielen. Der Fokus liegt dabei auf dem Wirkmodell von Gesundheitsförderung Schweiz und dem Friendly Works Space Lable. Die Resultate der Arbeit zeigen auf, dass, obwohl das Lable die Standards hoch setzt, das Potenzial der Wirkung von Führungsverhalten und Unternehmenskultur auf die psychische Gesundheit in den Tools von Gesundheitsförderung Schweiz noch nicht hinreichend erschlossen ist.

description: In this paper we compute the CMB bispectrum for bouncing models motivated by Loop Quantum Cosmology. Despite the fact that the primordial bispectrum of these models is decaying exponentially above a large pivot scale, we find that the cumulative signal-to-noise ratio of the bispectrum induced in the CMB from scales $\ell < 30$ is larger than $10$ in all cases of interest and therefore can, in principle, be detected in the Planck data.

Partial Description of Quantum States

description: One of the most central and controversial element of quantum mechanics is the use of non zero vectors of a Hilbert space (or, more generally, of one dimension subspaces) for representing the state of a quantum system. In particular, the question whether such a representation is complete has been debated since almost the early days of quantum mechanics. In this article, we develop an alternate way to formalize knowledge about the state of quantum systems, based solely on experimentally accessible elements, namely on outcomes of finite measurements. We introduce what we call partial description which, given a feasible measurement, indicates some outcomes which are known to be impossible (i.e. known to have a probability equal to 0 to occur) and hence have to be discarded. Then, we introduce partial states (which are partial descriptions providing as much information as possible) and compare this way to describe quantum states to the orthodox one, using vector rays. Finally, we show that partial states allow to describe quantum states in a strictly more expressive way that the orthodox description does.

description: Статья посвящена рассмотрению восприятия богатства и бедности гностиками, принадлежавшими к различным течениям. Если среди церковных христиан нормой было восхваление бедности и простоты жизни, то последователи учеников Валентина Птолемея, Гераклеона, Марка гордились своим высоким положением и богатством, ведь оно было доказательством их духовной высшей природы. Но существовал и противоположный взгляд на богатство — энкратизм, проповедующий полный отказ от благ этого мира. Его влияние заметно в «Деяниях Иуды Фомы» и некоторых сочинениях из Наг-Хаммади.
description: The article is devoted to the consideration of the perception of wealth and poverty by Early Christian Gnostics. The norm among Church Christians was the praising of poverty and simplicity of life, but followers of the Valentinus’ disciples Ptolemaeus, Heracleon, and Marcus were proud of their high position and wealth, because it was proof of their spiritual higher nature. There was also an opposite view of wealth — Encratism, preaching a complete rejection of the benefits of this world. Its influence is noticeable in the "Acts of Thomas" and some Nag Hammadi writings.

description: Малоизученное собрание донатистских проповедей, обнаруженное в Вене, даёт возможность взглянуть на жизнь донатистских общин Северной Африки по-новому. В отличие от большинства источников по истории раскола, эти тексты были предназначены не для религиозной полемики, а для наставления оглашенных. Статья посвящена теме милостыни, точнее вопросу о том, как понималась и обосновывалась практика милостыни в донатистских проповедях. Поскольку как в истории раскола, так и в развитии представлений о милостыне в западном христианстве большую роль сыграл Киприан Карфагенский, в статье рассмотрена и проблема влияния трудов Отца Церкви на взгляды донатистских проповедников.
description: Still under-investigated collection of Donatist sermons from Vienna provides us with a possibility to see the life of North African Donatist communities in a new light. While almost all our sources are polemical in nature, those texts were used in the Donatist catechesis. The paper deals with the treatment of almsgiving, its understanding and justification, in the Donatist preaching. Furthermore, the subject is considered in relation to the legacy of Cyprian of Carthago, due to his great influence on both the history of the Donatist schism and the development of the concept of almsgiving in the Western Christianity.

Stellar evolution models with entropy-calibrated mixing-length parameter: application to red giants

description: We present evolutionary models for solar-like stars with an improved treatment of convection that results in a more accurate estimate of the radius and effective temperature. This is achieved by improving the calibration of the mixing-length parameter, which sets the length scale in the 1D convection model implemented in the stellar evolution code. Our calibration relies on the results of 2D and 3D radiation hydrodynamics simulations of convection to specify the value of the adiabatic specific entropy at the bottom of the convective envelope in stars as a function of their effective temperature, surface gravity and metallicity. For the first time, this calibration is fully integrated within the flow of a stellar evolution code, with the mixing-length parameter being continuously updated at run-time. This approach replaces the more common, but questionable, procedure of calibrating the length scale parameter on the Sun, and then applying the solar-calibrated value in modeling other stars, regardless of their mass, composition and evolutionary status. The internal consistency of our current implementation makes it suitable for application to evolved stars, in particular to red giants. We show that the entropy calibrated models yield a revised position of the red giant branch that is in better agreement with observational constraints than that of standard models.
