description: We present spectroscopic observations of the remaining four candidate white dwarfs in Praesepe. All four candidates are quasars with redshifts between 0.8 and 2.8. One quasar, LB 6072, is observed to have a strong metal-line absorption system blueward of the quasar redshift. The lack of additional white dwarfs in Praesepe leaves the total known white-dwarf population of the cluster at five, well below the number expected from commonly-assumed initial mass functions, though several undiscovered cluster WDs may lie in the outer regions of the cluster. All known Praesepe member white dwarfs are concentrated within 0.6 deg of the cluster center, and the radial profile of cluster white dwarfs is quite similar to the profile of massive cluster stars. This profile is mildly inconsistent with that of ~1Mo cluster stars and suggests that the white dwarfs did not receive a velocity kick during the progenitor star's mass loss phases. If complete, the observed Praesepe white dwarf population is consistent with a steeper high-end initial-mass function than commonly assumed, though the calculated slopes are inconsistent with the present-day mass function of Praesepe. Searches for white dwarfs outside the core of Praesepe and further study of the white dwarf populations of additional open clusters is necessary to constrain further the underlying cause of the white dwarf deficit.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present a detailed analysis of the radio galaxy PKS 2250-351, a giant of 1.2 Mpc projected size, its host galaxy, and its environment. We use radio data from the Murchison Widefield Array, the upgraded Giant Metre-wavelength Radio Telescope, the Australian Square Kilometre Array Pathfinder, and the Australia Telescope Compact Array to model the jet power and age. Optical and infra-red data come from the Galaxy And Mass Assembly (GAMA) survey and provide information on the host galaxy and environment. GAMA spectroscopy confirms that PKS 2250-351 lies at z=0.2115 in the irregular, and likely unrelaxed, cluster Abell 3936. We find its host is a massive, `red and dead' elliptical galaxy with negligible star formation but with a highly obscured active galactic nucleus dominating the mid-infrared emission. Assuming it lies on the local M-sigma relation it has an Eddington accretion rate of lambda_EDD~0.014. We find that the lobe-derived jet power (a time-averaged measure) is an order of magnitude greater than the hotspot-derived jet power (an instantaneous measure). We propose that over the lifetime of the observed radio emission (~300 Myr) the accretion has switched from an inefficient advection dominated mode to a thin-disc efficient mode, consistent with the decrease in jet power. We also suggest that the asymmetric radio morphology is due to its environment, with the host of PKS 2250-351 lying to the west of the densest concentration of galaxies in Abell 3936.

Modeling non-linear effects in the redshift space two-point correlation function and its implications for the pairwise velocity dispersion

description: The anisotropies in the galaxy two-point correlation function measured from redshift surveys exhibits deviations from the predictions of the linear theory of redshift space distortion on scales as large 20 Mpc/h where we expect linear theory to hold in real space. Any attempt at analyzing the anisotropies in the redshift correlation function and determining the linear distortion parameter βrequires these deviations to be correctly modeled and taken into account. These deviations are usually attributed to galaxy random motions and these are incorporated in the analysis through a phenomenological model where the linear redshift correlation is convolved with the random pairwise velocity distribution function along the line of sight. We show that a substantial part of the deviations arise from non-linear effects in the mapping from real to redshift space caused by the coherent flows. Models which incorporate this effect provide a better fit to N-body results as compared to the phenomenological model which has only the effect of random motions. We find that the pairwise velocity dispersion predicted by all the models that we have considered are in excess of the values determined directly from the N-body simulations. This indicates a shortcoming in our understanding of the statistical properties of peculiar velocities and their relation to redshift distortion.

description: It is demonstrated that power-laws which are modified by logarithmic corrections arise in supercorrelated systems. Their characteristic feature is the energy attributed to a state (or value of a general cost function) which depends nonlinearly on the phase space distribution of the constituents. A onedimensional dissipative deterministic model is introduced which is attracted to a supercorrelated state (phase space entrainment). Extensions of this particular model may have applications in the study of transport and equilibration phenomena, particularly for supply and information networks, or for chemical and biological nonequilibrium systems, while the qualitative arguments presented here are believed to be of more general interest.

description: We present self-dual N=2 supergravity in superspace for Euclidean seven dimensions with the reduced holonomy G_2 \subset SO(7), including all higher-order terms. As its foundation, we first establish N=2 supergravity without self-duality in Euclidean seven dimensions. We next show how the generalized self-duality in terms of octonion structure constants can be consistently imposed on the superspace constraints. We found two self-dual N=2 supergravity theories possible in 7D, depending on the representations of the two spinor charges of N=2. The first formulation has both of the two spinor charges in the {\bf 7} of G_2 with 24 + 24 on-shell degrees of freedom. The second formulation has both charges in the {\bf 1} of G_2 with 16 + 16 on-shell degrees of freedom.

description: Rural areas are faced with the rising demographic, economic and social challenges such as aging society, migration due to the attraction of cities, centralization of services or loss of jobs, in part triggered by the increasing mobility. It is argued that social innovation can support rural development and, therefore, it has become a very popular concept. Yet, its definition and understanding remain a highly debated issue. The paper presents the concept of social innovation as a vital element for supporting rural areas in facing their developmental challenges. The example of social agriculture shows how social innovation works and how it can contribute to both meeting social needs and efficient use of local resources. The methodology applied in the study consisted of both literature review and a case study. The literature review deals with the concept of social innovations, social agriculture as well as the importance of social innovations in rural development and the role of public policy in supporting social innovations in rural areas. The case study is part of a local project done in 2016/17 in the province of Bolzano, whereby the potential of social agricultural practices was analysed through a comparison between already existing social agricultural practices in Europe and interviews conducted with local farmers in the province of Bolzano. The paper argues that social innovations can support rural development and rural development policy has an important role to play in catalysing social innovations by creating empowering settings for rural communities.

 Rhabdepyris luteipennis Evans, 1965: 114, 116, 117, 118–119; Gordh & Móczár, 1990: 148.
This species was known from Nicaragua, Panama, Trinidad and Brazil (Pará). Now, it is recorded for the first time from Amazonas of Brazil.
When Evans (1965) described this species he included two males, one from Panama and the other from Trinidad and Tobago, with the shape of mesopleural foveae very different from those of the allotype and rest of the series (state of Pará – Brazil and Nicaragua). In these specimens the upper foveae is long (Fig. 38), about 0.6x as long as the lower fovea and also wide, and the lower fovea is large and just slightly constricted medially, whereas most of the other males including the allotype has the upper foveae short (Fig. 39), about 0.25x as long as the lower fovea and triangular, and the lower fovea conspicuously constricted medially. Here we also observed these two patterns of mesopleural foveae in the specimens from Brazilian Amazon.
Besides, the specimens with large mesopleural foveae have mandible with four teeth (Fig. 40), propodeal disc with paramedian carinae converging posteriorly (Fig. 41) and notaulus very wide (Fig. 42), whereas the specimens with small mesopleural foveae as the allotype have mandible with five teeth (Fig. 43), propodeal disc with paramedian carinae diverging posteriorly (Fig. 44) and notaulus not wide (Fig. 45).
We believe that these patterns correspond to two different species as pointed out by Evans (1965), but it is not possible to know which one is the correct male for this species.

description: The hard X-ray source IGR J16318-4848 was recently discovered by the INTEGRAL observatory (Courvoisier et al.) and subsequently uncovered in archival data of ASCA observations in 1994 (Murakami et al.). We present results of a detailed analysis of the ASCA data. The spectrum of the source in the 0.5--10 keV band is extraordinarily hard and is virtually unobservable below 4 keV because of strong photoabsorption NHL L>4e23 cm^-2. The 4--10 keV emission is dominated by a Kalpha line of neutral or weakly ionized iron with an equivalent width of \~2.5 keV. There is also an indication for a second line at ~7 keV. Our analysis of archival observations of the IGR J16318-4848 infrared counterpart, discovered by Foschini et al., shows that the point source is detected at different wavelengths in the 1--15 micron range. The available data suggest that IGR J16318-4848 is an X-ray binary system enshrouded by a dense envelope. It is possible that the source is a wind-fed high-mass X-ray binary similar to GX 301-2. We argue that IGR J16318-4848 might be the first representative of a previously unknown population of highly absorbed galactic X-ray sources, which remained undetected with X-ray missions before INTEGRAL.

description: Space Charge (SC) distortions are some of the main issues for high-resolution Time Projection Chambers (TPC). The two main SC sources are those from primary ionizations and those that result from amplification stages. The gain stages are required to increase the electron signal above electronics noise levels, but this inevitably creates extra ions. These ions can enter the drift region and distort the electric field, and thus lower the detector performance. We will present a brief motivation for our Ion Back Flow (IBF) studies along with explanations of existing techniques and our simulation results to reduce IBF. We propose several mesh structures along with static bi-polar gating. Further, we discuss position distortions in electron trajectories due to a static bi-polar grid and use these distortions to compensate for non-linear responses of our Zig-Zag pad readout.

description: We present the lattice formulation of effective Lagrangians in which chiral symmetry is realized nonlinearly on the fermion fields. In this framework both the Wilson term removing unphysical doubler fermions and the fermion mass term do not break chiral symmetry. Our lattice formulation allows us to address non-perturbative questions in effective theories of baryons interacting with pions and in models involving constitutent quarks interacting with pions and gluons. With the presented methods, a system containing a non-zero density of static baryons interacting with pions can be studied on the lattice without encountering a complex action problem. This might lead to new insights into the phase diagram of strongly interacting matter at non-zero chemical potential.

description: Traditional farming systems and other activities such as craftsmanship (e.g. manufacturing activities, local food production), represent a sustainable example of human integration with the nature. Their maintenance and development, with opportune adaptations to the current socio-economic situation and cultural/technological advancements are, therefore, valuable (Gobattoni et al., 2015). Agriculture has long been one of the main driving forces shaping landscape. However, since the 1950s, the role played by the agricultural sector in society has changed as a consequence of mechanization and technological advances, globalisation processes and new social needs (Randelli et al., 2014; Van Eupen et al., 2012). In post-war Europe, industrialization and new demographic trends have led to the Urbanization phenomenon (Schewenius et al., 2014), with the rapid growth of cities, soil sealing through intensified construction and the depopulation of rural areas (Crafts and Toniolo, 1996). The deep transformations experienced by agriculture have impacted not only the rural community economy, employment and social dynamics, but also the nature and the environment (Schouten et al., 2013; Hanley et al., 2012; McManus et al., 2012) and, in general, on the supply of the so-called ecosystem and landscape services (De Groot et al., 2010; Hermann et al., 2011; Zanten et al., 2014). The paper deals with the presentation of the role of the National Rural Development Programme 2014-2020 in the development of rural regions of Slovakia. The number of supported projects, allocation of resources, and their efficiency will be evaluated with respect to regional dispersion and innovative potential of supported projects.
HI Imaging Observations of Superthin Galaxies. I. UGC7321

description: We have used the Very Large Array to image the isolated ``superthin'' galaxy UGC7321 in the HI line with a spatial resolution of 16'' and a spectral resolution of 24 kHz (5.2 km/s). We have reached a sensitivity of ~0.38 mJy/bm per channel, which corresponds to a column density of 8 x 10**{18} cm**{-2} (1 sigma). UGC7321 has a gas-rich disk with M_HI = (1.06 +/- 0.01) 10**9 Msun and MHI/LB = 1.0 (solar units), and no detectable radio continuum emission (F_CONT = 0.41 +/- 0.25 mJy). The global \HI distribution of UGC 7321 is rather symmetric and extends to ~1.5 times the optical radius (D_HI = 8.65' +/- 0.15') at n_HI = 3 x 10**{19} atoms cm**{-2}). An ``integral sign'' warp is observed in the HI disk, commencing near the edge of the stellar distribution, and twisting back toward the equatorial plane in the outermost regions. In addition, the position-velocity diagram suggests the presence of a bar or inner arm within ~40'' from the center. The rotation curve of UGC7321 is slowly rising; it reaches its asymptotic velocity of ~110 km/s ~2.5' from the center (about 0.9 optical radii) and declines near the edge of the HI disk. The ratio of the inferred dynamical mass to the mass in gas and stars is ~12, implying that UGC7321 is a highly dark-matter dominated galaxy.

description: The main aim of the study was an assessment of the strategic factors (goals, tasks) for local administrative units (LAU). To solve this problem, the authors used the fuzzy analytic hierarchy process (FAHP) based on experts’ opinions. The application of the FAHP extends the variety of the analytical tools used for constructing development strategies for administrative units and enables making more detailed plans for them. At the same time, it allows the assessed strategic factors to be arranged in a hierarchy of importance which should lead to a more realistic distribution of the planned activities over time, thus accelerating the development of the territorial units. The research was based on data from a survey with the councillors of the urban and rural municipality of Bogatynia in 2017.

description: Recently, superconductivity was discovered at very low densities in slightly misaligned graphene multilayers. Surprisingly, despite extremely low electronic density (about $10^{-4}$ electrons per unit cell), these systems realize strong-coupling superconductivity, with the transition temperature being a large fraction of the Fermi energy ($T_c\sim 0.1 ε_F$). Here we propose a qualitative explanation for this remarkable phenomenon, highlighting similarities and qualitative differences with the conventional uniform high-density superconductivity. Most importantly, we find that periodic superimposed potential generically enhances local interactions relative to nonlocal (for instance, Coulomb) interactions. In addition, the density of states is enhanced as well, exponentially in modulation strength for low lying bands in some cases. Combination of these two effects makes moiré systems natural intermediate or strong-coupled superconductors, with potential for very high transition temperatures.

description: Through a comprehensive approach that combines ecological restoration, historic context, and sustainable design principles, this project aims to create a harmonious coexistence between urban development and the natural environment to set a precedent for ecologically sensitive urban planning. The ultimate goal is to transform an urban watershed into a thriving ecosystem that supports salmon populations while also enhancing the ambiguous edge between water and land. Central to the project is the reconciliation of intricate historical narratives that have shaped the Colquitz River Watershed and the Gorge Waterway. Simultaneously, the project also confronts pressing issues such as water contamination, the impact of marine infrastructure, invasive species, and rising sea levels. Emphasizing community stewardship and reconciliation, these interventions seek to engage the community in safeguarding and nurturing local aquatic ecologies for generations to come.

description: The rotation of the plane of polarization of light passing through a non-magnetic material is known as natural optical activity or optical gyrotropy. The behavior of this effect in thin chiral conductors is of current interest. For example, the low frequency limit of gyrotropy in chiral 3D crystals, known as the gyrotropic magnetic effect (GME), is controlled by the orbital magnetic moment of electrons, which has been proposed to be relevant to current-induced switching in twisted bilayer graphene. We show that the GME is not limited to bulk materials but also appears for quasi-2d systems with minimal structure incorporated in the third direction. Starting from multi-band Kubo formula, we derive a generic expression for GME current in quasi-2d materials induced by low-frequency light, and provide a Feynman-diagrammatic interpretation. The relations between the 2d finite layered formula and 3d bulk formula are also discussed.

description: Recent calls of society to farmers are more and more focused on the protection of nature and providing public goods. At the same time, the development of climatic change emphasizes a need for environmentally friendly farming. These requirements are reflecting in the numbers of new regulations and other restrictive and motivating measures. The farmers should be prepared to react to these challenges by acquiring an appropriate skill set and seeking for innovation. In order to support them, there is a need to provide a system where the farmer could get such skills and cooperate with research. This system has existed for years, and the EU started to call it the Agricultural Knowledge Information System. The quality of the services provided by the system depends on the innovation potential of each actor in this system. The Institute of Agricultural Economics and Information (IAEI) is one of the actors, and it is interesting for us to know: What is the innovation potential of the IAEI?. In this paper, we are mapping the current position and innovation potential of the IAEI by using desk research and semi-structured interviews. According to the desk research, the IAEI plays a significant role in the process of AKIS in the Czech Republic. It represents a position of a mediator and a coordinator in the whole range of activities. According to the semi-structured questionnaires, the description of the innovation potential of the IAEI is meaningful when it is divided into several categories. In general, the ability to react to actual challenges depends on the research interest of a few individual researchers. The Institute supports this ability by providing access to several information channels. The ability to use modern technologies is improving thanks to new young employees. The recently established set of changes is the encouraging shift towards higher flexibility. Unfortunately, the administrative burden is still the primary barrier to innovation potential of the IAEI.

description: We present a neutron diffraction study of the magnetic structure of single crystal PrO2 under applied fields of 0-6 T. As the field is increased, changes are observed in the magnetic Bragg intensities. These changes are found to be irreversible when the field is reduced, but the original intensities can be recovered by heating to T > 122 K, then re-cooling in zero field. The antiferromagnetic ordering temperature TN = 13.5 K and the magnetic periodicity are unaffected by the applied field. We also report measurements of the magnetic susceptibility of single crystal PrO2 under applied fields of 0-7 T. These show strong anisotropy, as well as an anomaly at T = 122 +/- 2 K which coincides with the temperature TD = 120 +/- 2 K at which a structural distortion occurs. For fields applied along the [100] direction the susceptibility increases irreversibly with field in the temperature range TN < T < TD. However, for fields along [110] the susceptibility is independent of field in this range. We propose structural domain alignment, which strongly influences the formation of magnetic domains below TN, as the mechanism behind these changes.

description: The aim of the research was to assess the changes of competitiveness of Polish agriculture compared to other European countries with similar structure of production: Denmark, Germany, the Czech Republic, Slovakia, Hungary, Estonia, Latvia and Lithuania. With Poland’s accession to the EU, these countries became the competitors for Polish food producers and exporters on the Single European Market. Competitiveness of agriculture was indicated by the potential of production (i.e. resources of factors of production, relations between them, area and economic structures of farms) and productivity of production factors. The research was conducted for the years 2005-2013 and was based on Eurostat data. The results showed the persistence of a relatively low competitiveness of Polish agriculture against the agriculture of the selected countries.

description: Submarine debris flow can damage oil and gas transport pipelines with potentially adverse consequences to the environment and to the industrial activity itself. The deposition process of submarine debris flow, which is related to the flow viscosity, is complex due to the slurry diffusion process that happens during the interaction of water and slurry. In addition, a quantitative characterization of the characterize the flow mechanism as influenced by the material density during the deposition process remains a scientific challenge. To fundamentally understand the mechanisms of solid-fluid interactions in fast-flowing submarine debris flows, a series of three-dimensional (3D) numerical simulations using Computational Fluid Dynamics (CFD) were conducted. The Herschel- Bulkley (HB) model was used to define the submarine slurry’s rheological characterization as calibrate through simple rheological experiment. Results reveal that deposition is a mass diffusion process. Shear stress at the bottom and at the top of the slurry leads to velocity differences in the vertical direction which in turn generates a huge vortex, which contributed to a separation of slurry into two parts: the frontal head, and the tail. The velocity difference in vertical direction is helpful for hydroplaning. For higher slurry viscosity case, the flow profile is longer and thicker with a front head that has a lower averaged densities and sharper head angles. In addition, highly viscous slurries have lower average frontal velocities during the deposition process. The mixture density decreases in two stages: quick decreasing stage and stable decreasing stage. In the first stage, the slurry expands quicker than the second stage. Higher viscosities also lead to larger volume expansions which consequently leads to quicker density decrease.

description: We consider the observation of stellar-mass black holes binaries with the Laser Interferometer Space Antenna (LISA). Preliminary results based on Fisher information matrix analyses have suggested that gravitational waves from those sources could be very sensitive to possible deviations from the theory of general relativity and from the strong equivalence principle during the low-frequency binary inspiral. We perform a full Markov Chain Monte Carlo Bayesian analysis to quantify the sensitivity of these signals to two phenomenological modifications of general relativity, namely a putative gravitational dipole emission and a non-zero mass for the graviton, properly accounting for the detector's response. Moreover, we consider a scenario where those sources could be observed also with Earth-based detectors, which should measure the coalescence time with precision better than $1 \ {\rm ms}$. This constraint on the coalescence time further improves the bounds that we can set on those phenomenological deviations from general relativity. We show that tests of dipole radiation and the graviton's mass should improve respectively by seven and half an order(s) of magnitude over current bounds. Finally, we discuss under which conditions one may claim the detection of a modification to general relativity.

X-ray observations of 4 Draconis: symbiotic binary or cataclysmic triple?

description: We present the first X-ray observations of the 4 Draconis system, consisting of an M3III giant with a hot ultraviolet companion. It has been claimed that the companion is itself an AM Her-type binary system, an identification that places strong constraints on the evolution of cataclysmic variables. We find that the X-ray properties of 4 Draconis are consistent with the presence of an accreting white dwarf, but not consistent with the presence of an AM Her system. We conclude that 4 Dra is therefore most-likely a symbiotic binary containing a white dwarf accreting material from the wind of the red giant. The X-ray spectrum of 4 Dra is sometimes dominated by partially-ionised photoelectric absorption, presumably due to the wind of the red giant. We note that X-ray monitoring of such systems would provide a powerful probe of the wind and mass-loss rate of the giant, and would allow a detailed test of wind accretion models.

description: The aim of the study was an assessment of the quality of life in the urban-rural commune of Opalenica based on the opinion of its residents. The article makes references to local development dilemmas and presents the results of a questionnaire survey conducted in the commune. The respondents had the highest opinion about social aspects of life, especially the functioning of the private sector. They found the economic conditions, especially their salaries, to be the biggest drawbacks. The more concerned a particular issue was with the direct functioning of a household, the more unequivocal the respondents’ opinions were.

description: We apply the supersymmetry approach to one-dimensional quantum systems with spatially-dependent mass, by including their ordering ambiguities dependence. In this way we extend the results recently reported in the literature. Furthermore, we point out a connection between these systems and others with constant masses. This is done through convenient transformations in the coordinates and wavefunctions.

description: The main purpose of this paper was to identify the determinants of farm revenues in the EU-15 countries. The study was based on FADN regional data for 2011-2013. Factor analysis was used to address the above issue. Based on this study, it may be concluded that the key determinants of farming revenues in the EU-15 countries are as follows: size of the farm (measured both with the production potential and with the production value), operating subsidies, production intensity and plant production yields.
