description: This article presents findings with regard to mental models of the shape of the earth, location of people on earth and the day/night cycle, established on the basis of statements of 49 polish children aged from 5 to 8 years. During the interviews, the children made moving representations of the day and night sky and explained the position of and mutual relations between the earth, sun and moon using selfmade plasticine models. The article establishes a high degree of similarity with the Vosniadou and Brewer models and states that children’s astronomical knowledge mainly comes from extracurricular sources of information.
The Entrepreneurial Imperative: Advancing from Incremental to Radical Change in the Academic Library

description: "The future academic library will carry forward these network and digital revolutions and also integrate a more market-based, customized, and entrepreneurial approach to the packaging and delivery of information. Academic libraries will become centers for research and development in the application of technology to information creation and use. They will become aggregators and publishers, and not just consumers of scholarly information. They will function as campus hubs for working with faculty on the integration of technology and electronic resources into teaching and research. They will be regional and national centers for lifelong learning opportunities for information professionals, and they will be providers of information services to broader academic, research and business communities. This vision for the academic library predicts a significant moderation in the cost increases for knowledge, acquisition, and access as new models of scholarly publishing are successfully launched. It envisions massive expansion and diversification in new learning communities. The vision includes a redefinition of the library as a virtual resource not limited by time and space, and therefore not dependent on buildings for the housing, use, and servicing of information. The vision sees a repositioning of the academic library as a successful competitor in the information marketplace for new business, and for corporate, foundation, and federal investment. My objectives in this paper are to acknowledge the revolutionary environment in which academic libraries are developing, to outline the nature of entrepreneurship and innovation, and their relevance to library advancement. I will discuss the impact of changes in global learning and scholarly communication on library entrepreneurial opportunities, and relate recent experiences in the Libraries at Johns Hopkins University as a case study in entrepreneurial activity. I will then define several key elements for successful entrepreneurial development in the academic library." -- page 2
The substitution effects on electronic structure of iron selenide superconductors

description: The influence of a partial substitution with S, Te, Co, Ni and Cu atoms on the electronic structure of the FeSe superconductor has been investigated within the density functional theory. The results of the supercell calculations reveal distinct changes of electronic structures of the substituted FeSe systems, which can be responsible for their superconducting properties. The replacement of Se atoms by Te or S ones yields imperfect nesting between the holelike and electronlike Fermi surface (FS) sheets, which enhances magnetic fluctuations responsible for superconducting pairing, thus leading to higher values of the superconducting critical temperatures. Meanwhile, the substitutions with transition-metal atoms for iron sites make more substantial changes of the FSs topology, since the holelike cylinders shrink at the cost of an enlargement of the electronlike ones. Thus, the superconducting pairing, driven by the nesting between these sheets, weakens and superconductivity disappears for a small percentage of dopants. The results support the idea of spin-fluctuation mediated superconductivity in iron chalcogenides.

description: Based on multiyear INTEGRAL observations of SS433 in 2003-2011, a composite IBIS/ISGRI 18-60 keV orbital light curve is constructed around zero precessional phases psi_{pr}= 0 at the maximim accretion disk opening angle. It shows a peculiar shape with significant excess near the orbital phase phi_orb= 0.25, which is not seen in the softer 2-10 keV energy band. The 40-60 keV orbital light curve demonstrates two almost equal humps at phases \sim 0.25 and \sim 0.75, most likely due to nutation effects of the accretion disk. The nutational variability of SS433 in 15-50 keV with a period of 6.290 days is independently found from timing analysis of Swift/BAT data. The change of the off-eclipse 18-60 keV X-ray flux with the precessional phase shows a double-wave form with strong primary maximum at psi_{pr}= 0 and weak but significant secondary maximum at psi_{pr}= 0.6. A weak variability of the 18-60 keV flux in the middle of the orbital eclipse correlated with the disk precessional phase is also observed. The joint analysis of the broadband 18-60 keV orbital and precessional light curves confirms the presence of a hot extended corona in the central parts of the supercritical accretion disk and constrains the binary mass ratio in SS433 in the range 0.5>q>0.3, suggesting the black hole nature of the compact object.

description: In this paper we focus on scattering amplitudes in maximally supersymmetric Yang-Mills theory and define a long sought-after geometry, the loop momentum amplituhedron, which we conjecture to encode tree and (the integrands of) loop amplitudes in spinor helicity variables. Motivated by the structure of amplitude singularities, we define an extended positive space, which enhances the Grassmannian space featuring at tree level, and a map which associates to each of its points tree-level kinematic variables and loop momenta. The image of this map is the loop momentum amplituhedron. Importantly, our formulation provides a global definition of the loop momenta. We conjecture that for all multiplicities and helicity sectors, there exists a canonical logarithmic differential form defined on this space, and provide its explicit form in a few examples.

description: The OPERA experiment aims at the direct confirmation of the leading oscillation mechanism in the atmospheric sector looking for the appearance of $ν_τ$ in an almost pure $ν_μ$ beam (the CERN CNGS beam). In five years of physics run the experiment collected $17.97 \times 10^{19}$ p.o.t. The detection of $τ$s produced in $ν_τ$ CC interactions and of their decays is accomplished exploiting the high spatial resolution of nuclear emulsions. Furthermore OPERA has good capabilities in detecting electron neutrino interactions, setting limits on the $ν_μ \rightarrow ν_{e}$ oscillation channel. In this talk the status of the analysis will be presented together with updated results on both oscillation channels.

REMARKS: Rondani (1857: 92) described both sexes of Eumerus lasiops without specifying the exact number of specimens and not giving a range of lengths. Two specimens in the MZUF are determined here to not belong to the type series: one from “ Etruria ” (= Tuscany), which is not the type locality, and one whose label bears a date of capture subsequent to the date of the original description. These are the only specimens labeled as Eumerus lasiops that we found in all the museums we visited.

title: Cognitive and clinical correlates of early-stage psychosis: Associations with functioning and the feasibility of a cognitive training intervention
Creators: name: Haining, Kate
Publisher: name: University of Glasgow
Year: 2022

description: Schizophrenia is associated with a broad range of adverse outcomes - including suicidality and self-harm and impairments in cognitive performance and functioning - that are already present during early stages, including in the clinical high-risk for psychosis (CHR-P) state and first-episode psychosis (FEP). This thesis sought to target several key gaps in existing research literature which limit our current understanding of early-stage psychosis. To this end, the overarching aim of this thesis was to investigate cognitive and clinical correlates of early-stage psychosis including associations with functioning and the feasibility of a computerised cognitive training intervention. This thesis presents four studies which provide insights with regard to early detection and intervention in the early stages of psychosis. Chapter 2 investigates the prevalence of suicidality and non-suicidal self-harm among community-recruited CHR-P and FEP participants as well as factors associated with current suicidal ideation in the CHR-P group. Meanwhile, Chapters 3 and 4 harness machine learning methods to study cognition in a sample of CHR-P participants primarily recruited from the community. Specifically, Chapter 3 leverages supervised machine learning methods to examine the relationship between cognitive impairment and functioning while Chapter 4 employs unsupervised machine learning methods to examine cognitive heterogeneity and its association with both clinical and functional outcome. Finally, Chapter 5 investigates whether neuroplasticity-based computerised cognitive training can improve cognition and enhance gamma-band activity in a small sample of CHR-P and FEP participants. Overall, these studies indicate that a considerable proportion of CHR-P and FEP participants experience adverse outcomes, emphasising the need for novel early detection and intervention strategies in the community. Findings are discussed in relation to the feasibility of digital detection and intervention strategies; the need for more tailored and personalised approaches to treatment; the need to develop more accurate models for effective clinical decision-making; and the importance of including psychiatric controls as a reference point. In sum, this thesis builds upon the existing literature and provides insights which have implications for both research and clinical practice.

description: Nonlinear complex network-coupled systems typically have multiple stable equilibrium states. Following perturbations or due to ambient noise, the system is pushed away from its initial equilibrium and, depending on the direction and the amplitude of the excursion, might undergo a transition to another equilibrium. It was recently demonstrated [M. Tyloo, J. Phys. Complex. 3 03LT01 (2022)], that layered complex networks may exhibit amplified fluctuations. Here I investigate how noise with system-specific correlations impacts the first escape time of nonlinearly coupled oscillators. Interestingly, I show that, not only the strong amplification of the fluctuations is a threat to the good functioning of the network, but also the spatial and temporal correlations of the noise along the lowest-lying eigenmodes of the Laplacian matrix. I analyze first escape times on synthetic networks and compare noise originating from layered dynamics, to uncorrelated noise.

CURRENT STATUS: junior synonym of Eumerus strigatus (Fallén, 1817) (Peck 1988: 163, Belcari et al. 1995a: 16).
REMARKS: Rondani (1857: 90) described Eumerus melanopus from one male and an unspecified number of females: “ Semel exemplar masculum … inveni. Foeminam in Etruria captam a D. Piccioli accepi [Once I found a male specimen … I received the female collected in Etruria by Dr. Piccioli]”. Only one of the two MZUF males belongs to the type series because Rondani mentioned just one male in his original description. These males did not have any label indicating their type status. We are unable to single out the male upon which Rondani based his description. We leave the recognition of the male syntype to a future specialist. Not included in the type series is an additional male in the MSNPV from “ Etruria (= Tuscany)”, which is not the male type locality. No female type material was found in this study and is presumed lost.

Frankenstein: Brightness profile reconstruction at super-resolution
Creators: name: Jennings, Jeff
Publisher: name: Zenodo
Year: 2020

description: Interferometric observations of the mm dust distribution in protoplanetary discs now show a ubiquity of annular gaps and rings, as well as a nontrivial occurrence rate of asymmetric substructures. The identification and accurate characterization of these features is critical to probing the physical processes responsible. This poster summarizes Frankenstein, an open source code that recovers the 1D brightness profile of a disc at super-resolution. The code uses a nonparametric, fast (<1 min) Gaussian process to directly fit the 1D visibility distribution, yielding an accurate match of the visibility amplitudes to longer baseline (typically by a factor of 2 - 5) than the Fourier equivalent of a CLEAN brightness profile. This yields a more accurate constraint on the widths and amplitudes of disc gaps and rings, and often an identification of substructures not seen in the source’s CLEAN image.

description: We present temperature dependent switching measurements of the Co/Ni multilayered free element of 75 nm diameter spin-valve nanopillars. Angular dependent hysteresis measurements as well as switching field measurements taken at low temperature are in agreement with a model of thermal activation over a perpendicular anisotropy barrier. However, the statistics of switching (mean switching field and switching variance) from 20 K up to 400 K are in disagreement with a Néel-Brown model that assumes a temperature independent barrier height and anisotropy field. We introduce a modified Néel-Brown model thats fit the experimental data in which we take a $T^{3/2}$ dependence to the barrier height and the anisotropy field due to the temperature dependent magnetization and anisotropy energy.

description: We construct a toy model for holographic superconductor with non linear Maxwell field in the frame of modified gravity. By probe the bulk background by non linear Maxwell fields we show that superconductivity happens under a specific critical temperature. The effect of the non linear Maxwell field and non linear curvature corrections have been studied by analytical matching methods. We conclude that the non linearity in Maxwell field and curvature coupling make condensation harder.

Opportunities for systematic change in the academic research library: elements of the post-digital library

description: This paper, based on a talk delivered at the University of Leeds on 19 April 2011, seeks to outline a series of important trends that are influencing the roles and responsibilities of the academic research library, and a program of radical collaboration that would enable deeper integration of resources and a more systemic approach to the critical collection and service challenges. The academic research library must sustain its core responsibilities, albeit in an increasingly digitized, networked and mobile condition, enrich fundamental relationships with its user communities, and assume powerful new roles in support of learning and scholarship. New measures of quality, impact, productivity, innovation and leadership must be advanced. The paper suggests that the evolution of the academic library will focus more on an evolving period of polygamy, parabiosis and particularism, as we think beyond the transition to electronic and more about a post-digital context.

description: q-Gaussians are probability distributions having their origin in the framework of Tsallis statistics. A continuous real parameter q is characterizing them so that, in the range 1 < q < 3, the q-functions pass from the usual Gaussian form, for q close to 1, to that of a heavy tailed distribution, at q close to 3. The value q=2 corresponds to the Cauchy-Lorentzian distribution. This behavior of q-Gaussian functions could be interesting for a specific application, that regarding the analysis of Raman spectra, where Lorentzian and Gaussian profiles are the line shapes most used to fit the spectral bands. Therefore, we will propose q-Gaussians with the aim of comparing the resulting fit analysis with data available in literature. As it will be clear from the discussion, this is a very sensitive issue. We will also provide a detailed discussion about Voigt and pseudo-Voigt functions and their role in the line shape modeling of Raman bands. We will show a successfully comparison of these functions with q-Gaussians. The role of q-Gaussians in EPR spectroscopy (Howarth et al., 2003), where the q-Gaussian is given as the "Tsallis lineshape function", will be reported. Two examples of fitting Raman D and G bands with q-Gaussians are proposed too.

description: The problem of influence maximization, i.e., finding the set of nodes having maximal influence on a network, is of great importance for several applications. In the past two decades, many heuristic metrics to spot influencers have been proposed. Here, we introduce a framework to boost the performance of any such metric. The framework consists in dividing the network into sectors of influence, and then selecting the most influential nodes within these sectors. We explore three different methodologies to find sectors in a network: graph partitioning, graph hyperbolic embedding, and community structure. The framework is validated with a systematic analysis of real and synthetic networks. We show that the gain in performance generated by dividing a network into sectors before selecting the influential spreaders increases as the modularity and heterogeneity of the network increase. Also, we show that the division of the network into sectors can be efficiently performed in a time that scales linearly with the network size, thus making the framework applicable to large-scale influence maximization problems.

The Structure and Stability of Extended Circumplanetary Disks (or Exorings)
Creators: name: Speedie, Jess
Publisher: name: Zenodo

description: Large dips in the brightness for a number of stars have been observed, for which the tentative explanation is occultation of the star by a transiting circumplanetary disc or ring system. In order for the circumplanetary disk/rings to block the host star's light, the disk must be tilted out of the planet's orbital plane, which poses stability problems due to the radial extent of the disk required to explain the brightness dip durations. This work uses N-body integrations to study the structure and stability of circumplanetary disk/ring systems tilted out of the planet's orbital plane by the spinning planet's mass quadrupole. Simulating the disk as a collection of test particles with orbits initialized near the Laplace surface (equilibrium between tidal force from host star and force from planet's mass quadrupole), we find that many extended, inclined circumplanetary disks remain stable over the duration of the integrations (~3-16 Myr). Two dynamical resonances/instabilities excite the particle eccentricities and inclinations: the Lidov-Kozai effect which occurs in the disk's outer regions, and ivection resonance which occurs in the disk's inner regions. Our work places constraints on the maximum radial extent of inclined circumplanetary disk/ring systems, and shows that gaps present in circumplanetary disks do not necessarily imply the presence of exomoons.

description: Blazar spectra are one of the most important windows into the physical processes occurring along jets. The spectrum, composed from the different emitting regions along the jet, allows us to constrain the physical conditions in the jet. I present my work modelling blazar spectra using an extended inhomogeneous jet model with an accelerating, magnetically dominated, parabolic base transitioning to a slowly decelerating, conical section motivated by observations, simulations and theory. We set the inner geometry of our multi-zone model using observations of the jet in M87 which transitions from parabolic to conical at 10^5 Schwarzschild radii. This model is able to reproduce quiescent blazar spectra very well across all wavelengths (including radio observations) for a sample of 42 BL Lacs and FSRQs. Using this inhomogeneous model we are able to constrain the location at which the synchrotron emission is brightest in these jets by fitting to the optically thick to thin synchrotron break. We find that the radius of the jet at which the synchrotron emission is brightest (where the jet first approaches equipartition) scales approximately linearly with the jet power. We also find a correlation between the length of the accelerating, parabolic section of the jet and the maximum bulk Lorentz factor. In agreement with previous work we find that BL Lacs are low power blazars whereas FSRQs are high power blazars. Together with our simple jet power-radius relation this leads us to a deeper understanding of the physics underlying the blazar sequence.

description: "Academic libraries now hire an increasing number of individuals to fill professional librarian positions who do not have the master's degree in library science. Instead of appointing librarians with the traditional qualifying credential, they hire staff to fill librarian positions who hold a variety of qualifications, such as advanced degrees in subject disciplines, specialized language skills, teaching experience, or technology expertise. Academic libraries are also creating a wide range of new professional assignments in such areas as systems, human resources, fundraising, publishing, instructional technology, facilities management, and other specialties that demand diverse educational backgrounds. Additionally, responsibilities formerly carried out by librarians are frequently transferred to support staff and student employees. There is also a new cohort of MLS librarians who have received their degrees through distance rather than residential programs." -- page 42

description: Polycystic ovary syndrome (PCOS) and endometriosis are frequent diseases of the female reproductive tract causing high morbidity as they can significantly affect fertility and quality of life. Adipokines are pleiotropic signaling molecules secreted by white or brown adipose tissues with a central role in energy metabolism. More recently, their involvement in PCOS and endometriosis has been demonstrated. In this review article, we provide an update on the role of adipokines in both diseases and summarize previous findings. We also address the results of multi-omics approaches in adipokine research to examine the role of single nucleotide polymorphisms (SNPs) in genes coding for adipokines and their receptors, the secretome of adipocytes and to identify epigenetic alterations of adipokine genes that might be conferred from mother to child. Finally, we address novel data on the role of brown adipose tissue (BAT), which seems to have notable effects on PCOS. For this review, original research articles on adipokine actions in PCOS and endometriosis are considered, which are listed in the PubMed database.

description: Quantization of a toy model of a pseudointegrable Hamiltonian impact system is introduced, including EBK quantization conditions, a verification of Weyl's law, the study of their wavefunctions and a study of their energy levels properties. It is demonstrated that the energy levels statistics are similar to those of pseudointegrable billiards. Yet, here, the density of wavefunctions which concentrate on projections of classical level sets to the configuration space does not disappear at large energies, suggesting that there is no equidistribution in the configuration space in the large energy limit; this is shown analytically for some limit symmetric cases and is demonstrated numerically for some nonsymmetric cases.

description: Deterministic optical manipulation of fluorescent nanodiamonds (FNDs) in fluids has emerged as an experimental challenge in multimodal biological imaging. Designing and developing nano-optical trapping strategies to serve this purpose is an important task. In this letter, we show how chemically-prepared gold nanoparticles and silver nanowires can facilitate Opto-thermoelectric force to trap individual entities of FNDs using a long working distance lens, low power-density illumination (532 nm laser, 12 $μW/μm^2$). Our trapping configuration combines the thermoplasmonic fields generated by individual plasmonic nanoparticles and the opto-thermoelectric effect facilitated by the surfactant to realise a nano-optical trap down to a single FND 120 nm in diameter. We utilise the same trapping excitation source to capture the spectral signatures of single FNDs and track their position. By tracking the FND, we observe the differences in the dynamics of FND around different plasmonic structures. We envisage that our drop-casting platform can be extrapolated to perform targeted, low-power trapping, manipulation, and multimodal imaging of FNDs inside biological systems such as cells.

description: The key element in the Proton-Driven-Plasma-Wake-Field-Accelerator (AWAKE) project is the generation of highly uniform plasma from Rubidium vapor. The standard way to achieve full ionization is to use high power laser which can assure the over-barrier-ionization (OBI) along the 10 meters long active region. The Wigner-team in Budapest is investigating an alternative way of uniform plasma generation. The proposed Resonance Enhanced Multi Photon Ionization (REMPI) scheme probably can be realized by much less laser power. In the following the resonant pre-excitations of the Rb atoms are investigated, theoretically and the status report about the preparatory work on the experiment are presented.

description: By using first-principles calculations, we systematically investigated several observed phases of silicene on Ag(111) substrates and their electronic structures. We find that the original Dirac cone of silicene is about 1.5-1.7 eV deeply below the Fermi level and severely destroyed by the band hybridization between silicene and Ag in all the examined phases. Thus, silicene synthesized on Ag(111) substrates could not preserve its excellent electronic property and new method is needed to develop in synthesizing silicene with its Dirac cone surviving.

description: It is shown that each linear operator on a separable Hilbert space which generates a finite type I von Neumann algebra has, up to unitary equivalence, a unique representation as a direct integral of inflations of mutually unitary inequivalent irreducible matrices. This leads to a simplification of the so-called prime (or central) decomposition and the multiplicity theory for such operators. The concept of so-called p-isomorphisms between special classes of such operators is discussed. All results are formulated in more general settings; that is, for tuples of closed densely defined operators affiliated with finite type I von Neumann algebras.
