description: Gut microbes provide energy to the microbiota by digesting food residues and releasing metabolites for the gut, affecting the host if they enter the host's circulatory system. Conversely, intestinal metabolites can influence the composition, gene expression, and gut microbiota-derived metabolites. Structural changes and metabolic changes in the gut microbial community, as well as metabolic changes in the host's blood or tissues. tend to cause a variety of diseases, The point study of microbiome and metabolome can help discover microorganisms and metabolites that play key roles in the physiological and disease development processes and reveal related mechanisms.

description: Hierarchical assembly models predict a population of supermassive black hole (SMBH) binaries. These are not resolvable by direct imaging but may be detectable via periodic variability (or nanohertz frequency gravitational waves). Following our detection of a 5.2 year periodic signal in the quasar PG 1302-102 (Graham et al. 2015), we present a novel analysis of the optical variability of 243,500 known spectroscopically confirmed quasars using data from the Catalina Real-time Transient Survey (CRTS) to look for close (< 0.1 pc) SMBH systems. Looking for a strong Keplerian periodic signal with at least 1.5 cycles over a baseline of nine years, we find a sample of 111 candidate objects. This is in conservative agreement with theoretical predictions from models of binary SMBH populations. Simulated data sets, assuming stochastic variability, also produce no equivalent candidates implying a low likelihood of spurious detections. The periodicity seen is likely attributable to either jet precession, warped accretion disks or periodic accretion associated with a close SMBH binary system. We also consider how other SMBH binary candidates in the literature appear in CRTS data and show that none of these are equivalent to the identified objects. Finally, the distribution of objects found is consistent with that expected from a gravitational wave-driven population. This implies that circumbinary gas is present at small orbital radii and is being perturbed by the black holes. None of the sources is expected to merge within at least the next century. This study opens a new unique window to study a population of close SMBH binaries that must exist according to our current understanding of galaxy and SMBH evolution.

title: Produktion und Analyse eines Erklärvideos zum Thema Atombindung für die Sekundarstufe I
Creators: name: Kiebler, Margret Theres
Year: 2023

description: In der heutigen Zeit werden Erklärvideos immer häufiger von Schüler*innen zum eigenständigen Lernen, als auch von Lehrkräften im Unterricht verwendet. Die zahlreichen online auffindbaren Erklärvideos ermöglichen dies ohne große Schwierigkeiten. Allerdings existieren Erklärvideos, welche sich aus verschiedensten Gründen eher nicht zum Lernen eignen. Die Informationen können falsch dargestellt sein, fachdidaktische Aspekte werden vernachlässigt oder störende Inhalte verhindern einen reibungslosen Verarbeitungsprozess. Das Ziel dieser Masterarbeit ist es ein Erklärvideo über die Atombindung für die Sekundarstufe I zu konzipieren, welches die Lernprozesse von Schüler*innen unterstützt und flexibel im Unterricht eingesetzt werden kann. Dafür wurden Gestaltungsrichtlinien von Mayer (2014a) und Kulgemeyer (2020a) bei der Produktion des Erklärvideos berücksichtig. Bei den Gestaltungsrichtlinien handelt es sich um die Prinzipien der „Cognitive Theory of Multimedia Learning“ von Mayer (2014a) und um die „Qualitätskriterien zur Gestaltung für Erklärvideos“ von Kulgemeyer (2020a). Die Prinzipien von Mayer konzentrieren sich auf die Beziehung zwischen Text, Bildern und gesprochenem Inhalt und die Qualitätskriterien von Kulgemeyer fokussieren sich auf die didaktischen Aspekte einer Erklärung. Um ein fachwissenschaftlich angemessenes und fachdidaktisch fundiertes Erklärvideo zu produzieren wurde eine Sachanalyse und eine Schulbuchanalyse durchgeführt. Zusätzlich zum Erklärvideo wurde eine Lernaufgabe erstellt, in welcher Schüler*innen ihr neu erworbenes Wissen und Können festigen, vertiefen und erweitern sollen. Eine Evaluierung durch Fachkolleg*innen, welche sich das Erklärvideo und die Lernaufgabe angesehen haben, zeigte einen hohe Zuspruch. Alle Teilnehmer können sich vorstellen, das Erklärvideo in ihrem Chemieunterricht einzusetzen. Die freien Antworten der Teilnehmer zeigten auch, dass der Einsatz flexibel ist, da von ihnen Vorschläge zum eigenen Einsatz im Unterricht gemacht wurden, um den Nachteilen eines Erklärvideos entgegenzuwirken. Auf das erstellte Erklärvideo kann man auf Youtube mit folgendem Link: https://www.youtube.com/watch?v=qlqWZtAxgS0

description: This study extends our research on the GameSense responsible gambling program at MGM's United States-based gaming properties. In the present study, we will: 1) examine population-based trends in responsible gambling program effectiveness over time across 24 land-based casinos and 2) investigate how different property types (i.e., regional casinos vs. metropolitan casinos vs. Las Vegas casinos) might have varying responsible gambling program effectiveness among customers. We will analyze three repeated cross-sectional survey datasets collected prior to (i.e., Year 1 data) and following (i.e., Year 2 and 3 data) the implementation of the GameSense program at MGM properties in the U.S. Specifically, we will examine how levels of awareness of and engagement with the GameSense responsible gambling program might have changed over the three-year period, whether GameSense awareness and engagement are associated with gambling beliefs and behaviors in Year 3, and if there are any differences in the relationships between GameSense engagement, and gambling beliefs and behaviors, across property types.

Year: 2019

description: Recent scholarship has examined the complicated relationship between law and images.  This task-based study provides an initial entry point into the law and image discourse for law librarians who are subject specialists in foreign law and international law (FIL).  This study asks, how do law librarians interpret aspects of foreign law and international law in representational works of art?  Using six artworks held in European and American cultural heritage institutions, the researcher collected quantitative and qualitative data from members of the American Association of Law Libraries’ Special Interest Section for Foreign, Comparative and International Law.  The researcher analyzed study participants’ results according to the following questions: How does one “see the law” in an image that was not created for the purpose of showing the law?  How might an image’s inscrutable elements be separately identified from its known elements?  How might this separation be documented and recorded?

Creators: name: Watzka, Stefan
Year: 2022

description: Zahlreiche neuere Erkenntnisse aus der Biomedizin bestätigen, dass neben dem materiellen Körper noch ein immaterielles Prinzip existieren muss, das mit dem materiellen Körper eine funktionelle Einheit bildet. In der christlichen Tradition wird das besondere Verhältnis zwischen materiellem Körper und immaterieller Seele mit dem Begriff Inkarnation beschrieben (Vgl. Joh 1, 14), womit eigentlich die Geburt Jesu Christi als Menschwerdung Gottes bzw. als Inkarnation des logos gemeint ist. Im Rahmen dieser Masterarbeit wird das Leib-Seele-Verständnis der christlichen Offenbarung mit den jeweiligen Positionen Aristoteles‘ und Descartes‘ verglichen. Die Reflexion über das grundsätzliche Verständnis der Beziehung von Körper und Seele beginnt nämlich nicht mit der christlichen Offenbarung, sondern wird bereits von Aristoteles angestellt, für den die Seele die Form des Körpers darstellt. Eine konträre Position dazu nimmt hingegen Descartes ein, für den Seele und Körper fast vollständig getrennt sind. Aus der Reflexion über den Begriff Inkarnation heraus werden folgende Fragen beantwortet: Was unterscheidet die Inkarnation Jesu Christi von der Inkarnation bzw. vom Leib-Seele-Verständnis bei Aristoteles und Descartes? Überwindet die Inkarnation des Johannes-Evangeliums den Leib-Seele-Dualismus des Menschen per se, und wenn ja, wie? Falls das Prinzip der Inkarnation keine Singularität in der Person Jesu Christi, sondern nichts Anderes als die Logifizierung des Menschen bezeichnet, kann es dann Abstufungen oder einen Fortschritt der Inkarnation geben? Zusammenfassend will diese Masterarbeit einen Weg weisen, wie das Leib-Seele- Verhältnis jenseits von Monismus und Dualismus sinnvoll gedacht werden kann. Die Implikationen für die aktuelle Trans- und Posthumanismusdebatte werden dabei ausführlich gewürdigt.
Obscuring Fraction of Active Galactic Nuclei: Implications from Radiation-driven Fountain Models
Creators: name: Wada, Keiichi
Publisher: name: arXiv
Year: 2015
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Active galactic nuclei (AGNs) are believed to be obscured by an optical thick "torus" that covers a large fraction of solid angles for the nuclei. However, the physical origin of the tori and the differences in the tori among AGNs are not clear. In a previous paper based on three-dimensional radiation-hydorodynamic calculations, we proposed a physics-based mechanism for the obscuration, called "radiation-driven fountains," in which the circulation of the gas driven by central radiation naturally forms a thick disk that partially obscures the nuclear emission. Here, we expand this mechanism and conduct a series of simulations to explore how obscuration depends on the properties of AGNs. We found that the obscuring fraction f_obs for a given column density toward the AGNs changes depending on both the AGN luminosity and the black hole mass. In particular, f_obs for N_H \geq 10^22 cm^-2 increases from ~0.2 to ~0.6 as a function of the X-ray luminosity L_X in the 10^{42-44} ergs/s range, but f_obs becomes small (~0.4) above a luminosity (~10^{45} ergs/s). The behaviors of f_obs can be understood by a simple analytic model and provide insight into the redshift evolution of the obscuration. The simulations also show that for a given L_AGN, f_obs is always smaller (~0.2-0.3) for a larger column density (N_H \geq 10^23 cm^-2). We also found cases that more than 70% of the solid angles can be covered by the fountain flows.

description: In this paper we investigate the opportunities provided by the James Webb Space Telescope (JWST) for significant scientific advances in the study of solar system bodies and rings using stellar occultations. The strengths and weaknesses of the stellar occultation technique are evaluated in light of JWST's unique capabilities. We identify several possible JWST occultation events by minor bodies and rings, and evaluate their potential scientific value. These predictions depend critically on accurate a priori knowledge of the orbit of JWST near the Sun-Earth Lagrange-point 2 (L2). We also explore the possibility of serendipitous stellar occultations by very small minor bodies as a by-product of other JWST observing programs. Finally, to optimize the potential scientific return of stellar occultation observations, we identify several characteristics of JWST's orbit and instrumentation that should be taken into account during JWST's development.

COLLECTING HATE: COLLECTING, ARCHIVING, DISPLAYING, AND PROVIDING ACCESS TO HATE MATERIALS IN LIBRARIES AND CULTURAL HERITAGE INSTITUTIONS
Creators: name: Mahoney, Gillian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This study examines the history of hate materials in archives, libraries, and other cultural heritage institutions in the United States. This research was conducted to further understand how institutions collect, archive, preserve, and provide access to materials created by hate groups, in particular when these institutions serve populations against whom this hate is often directed. This study was most concerned with how institutions deal with hate materials in their collections policies. 

Six archivists or librarians at six institutions were interviewed, ranging from large university archives to small community based historical societies. The interviews were subsequently analyzed to assess whether archivists have considered the ethics and implications of collecting hate materials, and how they address these issues. This study found that archivists and other cultural heritage professionals believe strongly that hate materials can be important collection materials but did not have collections policies in place that explicitly mentioned hate materials.

description: Two concepts of centrality have been defined in complex networks. The first considers the centrality of a node and many different metrics for it has been defined (e.g. eigenvector centrality, PageRank, non-backtracking centrality, etc). The second is related to a large scale organization of the network, the core-periphery structure, composed by a dense core plus an outlying and loosely-connected periphery. In this paper we investigate the relation between these two concepts. We consider networks generated via the Stochastic Block Model, or its degree corrected version, with a strong core-periphery structure and we investigate the centrality properties of the core nodes and the ability of several centrality metrics to identify them. We find that the three measures with the best performance are marginals obtained with belief propagation, PageRank, and degree centrality, while non-backtracking and eigenvector centrality (or MINRES}, showed to be equivalent to the latter in the large network limit) perform worse in the investigated networks.

description: In the present work, we investigate how single- and multi-vortex-ring states can emerge from a planar dark soliton in three-dimensional (3D) Bose-Einstein condensates (confined in isotropic or anisotropic traps) through bifurcations. We characterize such bifurcations quantitatively using a Galerkin-type approach, and find good qualitative and quantitative agreement with our Bogoliubov-de Gennes (BdG) analysis. We also systematically characterize the BdG spectrum of the dark solitons, using perturbation theory, and obtain a quantitative match with our 3D BdG numerical calculations. We then turn our attention to the emergence of single- and multi-vortex-ring states. We systematically capture these as stationary states of the system and quantify their BdG spectra numerically. We find that although the vortex ring may be unstable when bifurcating, its instabilities weaken and may even eventually disappear, for sufficiently large chemical potentials and suitable trap settings. For instance, we demonstrate the stability of the vortex ring for an isotropic trap in the large chemical potential regime.

description: The aim of this report is to review tsunami evacuation zone mapping approaches and develop considerations based on social science research methods for the effective number and communication of tsunami evacuation zones on public-facing maps. Tsunami evacuation maps are a key tool used to manage and communicate tsunami hazard in Aotearoa New Zealand’s coastal communities. We have built an evidence base from the literature, as well as from primary data collection through case studies, interviews and focus groups in Aotearoa New Zealand, to understand the public’s understanding of tsunami evacuation zones and map design preferences. Based on this evidence base, we present a set of considerations based on various aspects of tsunami evacuation mapping in Aotearoa New Zealand

description: This study employed a quantitative approach to evaluate the accuracy of Aeon’s reporting systems in Wilson Library. An analysis of 27,561 transaction requests, which were made between July 1, 2015 and May 10, 2016, determined that variations in item ‘Location’ fields prevented Aeon from generating accurate statistics for Wilson’s collections. I found that human error caused problems in 560 (2.03%) of the records; in 3,311 (12.01%) of the records named collections and size indicators also appeared in the ‘Location’ field; in 2,407 (8.73%) multiple copies of a title were imported from the catalog into the Aeon request; and 2,159 additional records (representing a 7.83% increase) needed to be added to account for multiple volumes or boxes being grouped in the same request. I discuss what these numbers indicate about staff and patron use of Aeon and suggest changes that could mitigate these problems.

An Investigation of Inmate Book Requests as a Collection Development Tool
Creators: name: Fieldsteel, Julie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This study describes a survey of prison librarians and volunteers who have worked for prison book collectives within the past six months. The survey was conducted to explore what popular fiction and nonfiction materials inmates have requested from prison librarians and volunteers from external organizations.

Although the study was unable to effectively connect inmate demographic information to the kinds of book requests made, it still collected some valuable insight on which the most popular fiction and nonfiction materials among inmates are. Suggestions made include keeping prison library collections as diverse as possible, since inmates are often unfamiliar with public libraries and don’t know what materials are available.

description: We present ten young ($\lesssim$10 Myr) late-K and M dwarf stars observed in K2 Campaign 2 that host protoplanetary disks and exhibit quasi-periodic or aperiodic dimming events. Their optical light curves show $\sim$10-20 dips in flux over the 80-day observing campaign with durations of $\sim$0.5-2 days and depths of up to $\sim$40%. These stars are all members of the $ρ$ Ophiuchus ($\sim$1 Myr) or Upper Scorpius ($\sim$10 Myr) star-forming regions. To investigate the nature of these "dippers" we obtained: optical and near-infrared spectra to determine stellar properties and identify accretion signatures; adaptive optics imaging to search for close companions that could cause optical variations and/or influence disk evolution; and millimeter-wavelength observations to constrain disk dust and gas masses. The spectra reveal Li I absorption and H$α$ emission consistent with stellar youth (<50 Myr), but also accretion rates spanning those of classical and weak-line T Tauri stars. Infrared excesses are consistent with protoplanetary disks extending to within $\sim$10 stellar radii in most cases; however, the sub-mm observations imply disk masses that are an order of magnitude below those of typical protoplanetary disks. We find a positive correlation between dip depth and WISE-2 excess, which we interpret as evidence that the dipper phenomenon is related to occulting structures in the inner disk, although this is difficult to reconcile with the weakly accreting aperiodic dippers. We consider three mechanisms to explain the dipper phenomenon: inner disk warps near the co-rotation radius related to accretion; vortices at the inner disk edge produced by the Rossby Wave Instability; and clumps of circumstellar material related to planetesimal formation.

Synthesis and coordination chemistry of tridentate phosphine ligands: applications in homogeneous catalysis of levulinic acid
Creators: name: Omoruyi, Uwaila
Publisher: name: Imperial College London
Year: 2018

description: The work presented herein is concerned with the synthesis of polydentate phosphine ligands, their coordination chemistry and applications in homogenous catalysed hydrogenations of biomass derived levulinic acid (LA). Tripodal phosphine ligands, bearing a central nitrogen atom generally represented as NP3R and Py-NP2R (R = phenyl, cyclohexyl, tbutyl, Py = 2- or 4-picolylamine) were investigated along with the commercially available carbon centred CP3Ph ligand. The ligands were synthesized via a phosphorus based Mannich condensation reaction. The mixed arm ligand Py-NP2Ph coordinated to both Mo and W metal centres in a bidentate fashion. The study of the coordination behaviour of the symmetrical N-triphos ligand bearing phenyl substituent (NP3Ph) with Fe metal centre resulted in novel Fe(II), Fe(0) complexes in which the ligand is bidentate to the Fe metal centre. Additionally, an unexpected Ag(I) complex with κ3 coordinated mode was also isolated and characterised. The desired κ3 coordination of the symmetrical ligands (NP3Ph and CP3Ph) was achieved with Rh and Ru metal centres respectively. The novel [Rh(COD)(κ-NP3Ph)]BF4 and [Ru(CO3)CO(κ-CP3Ph)] complexes were evaluated for the hydrogenation of LA to gamma-valerolactone (GVL), 1,4-pentanediol (1,4-PDO) and 2-methyltetrahydrofuran (2-MTHF). The Rh complex [Rh(COD)(κ-NP3Ph)]BF4 was found to be inactive for LA hydrogenation. GVL and 1,4-PDO were successfully synthesized from LA using novel air stable ruthenium carbonate complex [Ru(CO3)CO(κ-CP3Ph)]. The complex achieved excellent GVL yields and a modest 1,4-PDO yield under the catalytic conditions employed. It was discovered to perform better than the commercially available Ru complex based on monodentate phosphine [RuH2(PPh3)4] under similar hydrogenation conditions.

description: Self-conscious emotions are fundamental to adaptive social behaviour. In contrast to basic emotions, they are thought to require cognitive representations of self and others to self-evaluative against social norms. Embarrassment, one self-conscious emotion, is experienced as an unpleasant emotional response to faux pas, social conspicuousness, and the like. Understanding the neural correlates of embarrassment plays a crucial role in expanding our knowledge of the brain basis of self-conscious emotions and their links to social cognition networks underpinning 'mentalizing' or 'theory of mind'. Neuroimaging meta-analysis allows us to synthesize available studies, providing a large sample, higher power, and more generalizable results. The current study aims to investigate the neural correlates of embarrassment using the coordinate based meta-analysis (CBMA) method and this registration records the state of the project before literature search started.

We extract the $M$-$c$ relation by measuring the density profiles of individual clusters instead of using stacked weak lensing signals. By performing Monte Carlo simulations, we demonstrate that although the signal-to-noise ratio for each individual cluster is low, the unbiased $M$-$c$ relation can still be reliably derived from a large sample of clusters by carefully taking into account the impacts of shape noise, cluster center offset, dilution effect from member or foreground galaxies, and the projection effect. Our results show that within error bars the derived $M$-$c$ relation for redMaPPer clusters is in agreement with simulation predictions. There is a weak deviation in that the halo concentrations calibrated by Monte Carlo simulations are somewhat higher than that predicted from ${\it Planck}$ cosmology.

Eigenmodal Analysis of Anderson Localization: Applications to Photonic Lattices and Bose-Einstein Condensates
Creators: name: Ying, Guanwen

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We present the eigenmodal analysis techniques enhanced towards calculations of optical and non-interacting Bose-Einstein condensate (BEC) modes formed by random potentials and localized by Anderson effect. The results are compared with the published measurements and verified additionally by the convergence criterion. In 2-D BECs captured in circular areas, the randomness shows edge localization of the high-order Tamm-modes. To avoid strong diffusive effect, which is typical for BECs trapped by speckle potentials, a 3-D-lattice potential with increased step magnitudes is proposed, and the BECs in these lattices are simulated and plotted.

description: Let $(R, \mathfrak{m}, k)$ denote a local Cohen-Macaulay ring such that the category of maximal Cohen-Macaulay $R$-modules $\textbf{mcm}\ R$ contains an $n$-cluster tilting object $L$. In this paper, we compute $G_1(R) := K_1(\textbf{mod}\ R)$ explicitly as a direct sum of a free group and a specified quotient of $\text{aut}_R(L)_{\text{ab}}$ when $R$ is a $k$-algebra and $k$ is algebraically closed (and $\text{char}(k)\neq 2$). Moreover, we give some explicit computations of $\text{aut}_R(L)_{\text{ab}}$ and $G_1(R)$ for certain hypersurface singularities.

Dark Matter Searches for Monoenergetic Neutrinos Arising from Stopped Meson Decay in the Sun

description: Dark matter can be gravitationally captured by the Sun after scattering off solar nuclei. Annihilations of the dark matter trapped and accumulated in the centre of the Sun could result in one of the most detectable and recognizable signals for dark matter. Searches for high-energy neutrinos produced in the decay of annihilation products have yielded extremely competitive constraints on the spin-dependent scattering cross sections of dark matter with nuclei. Recently, the low energy neutrino signal arising from dark-matter annihilation to quarks which then hadronize and shower has been suggested as a competitive and complementary search strategy. These high-multiplicity hadronic showers give rise to a large amount of pions which will come to rest in the Sun and decay, leading to a unique sub-GeV neutrino signal. We here improve on previous works by considering the monoenergetic neutrino signal arising from both pion and kaon decay. We consider searches at liquid scintillation, liquid argon, and water Cherenkov detectors and find very competitive sensitivities for few-GeV dark matter masses.

Kuidas portreteerida akadeemilist vaimu? Ülikoolimuuseumide identiteedimuutustest kahe viimase sajandi jooksul

description: HOW TO PORTRAY ACADEMIC SPIRIT. Identity changes in university museums over the last two centuries Mariann Raisma, MA, Director of the University of Tartu History Museum A university museum is like a window into the university. This statement is a concise characterisation of the essence of academic museums. This article examines the identity changes in university museums over the last two centuries and analyses the issues shaping the appearance and role of university museums today. University museums and collections are aggregates of the history of the social elite. Items for such museums are selected based on paradigm shifts and developments in perception of education and science. It is namely through the things preserved in university museums that we see clearly what humankind knows about nature, the universe and human beings. University-based museums are the oldest in Estonia, too: the University of Tartu’s Natural History Museum was established in 1802, while its sibling, the Art Museum, was born just a year later. Yet many of the university-owned museums in Estonia and worldwide are quite young and quite a few have the status of mere collections. For instance, the Museum of Tallinn University of Technology was reopened only in 2009. This article analyses types of university museums and the idea behind the concept of academic museums, using as an example the Ashmolean Museum of Oxford University. While the university museums existing in the 19th century focused on lecturing and research work, the 20th century saw the emergence of a new type of university-based museum that concentrated efforts on historically valuable science- and education-related collections and the history of their university. Two trends are discerned from analysis of such museums in Europe: the first stresses science (science museum/museum of history of science) and the second focuses on the university’s history (university museum), with historically valuable scientific materials serving the latter priority. This article highlights the typical issues of modern-day university museums, such as centralisation vs decentralisation, university history vs history of science and curator vs researcher, and discusses the public role of university museums.

description: Introduction: COVID-19 vaccines were considered as the most effective mode to prevent morbidity and mortality from COVID-19. However, similar to other vaccines, adverse events post-vaccination is expected. This reactogenicity to vaccines varies by type of vaccine and vaccine dose and has primarily been studied in clinical trials with homologous dosing of vaccines. However, due to variation in vaccine availability and perceived and actual risk of serious adverse events within a few months of vaccine rollout, heterologous schedules were implemented in different countries worldwide, including Australia. This thesis aims to: 1) describe the vaccine reactogenicity profiles of the different homologous and heterologous schedules from published studies, and 2) determine the reactogenicity of Therapeutic Goods Administration approved homologous and heterologous schedules using the AusVaxSafety data. Methods: The first study is a systematic review and meta-analysis guided by the PRISMA framework, which included randomised controlled trials, open trials and cohort studies involving participants 18 years old above who have received at least 2 doses of any WHO validated for emergency use COVID-19 vaccines. The second study is a prospective cohort study using the AusVaxSafety active surveillance system to determine risks of adverse events following the second or third dose of COVID-19 vaccination in the different homologous and heterologous schedules. Results and Conclusion: Findings from the systematic review indicated higher local and systemic reactogenicity of homologous mRNA schedules, and heterologous schedules with mRNA vaccines as second or third dose. Similarly, the AusVaxSafety cohort study suggested higher risk of adverse events in homologous mRNA vaccine schedules as well as heterologous schedules utilising mRNA vaccines as a second dose. Further studies exploring the heterogeneity in reporting frequencies of AEFIs, and cohort studies including all the AusVaxSafety-linked survey tools are recommended to determine optimal COVID-19 schedules for future vaccine guidelines.
Университетские музеи Украины: стадия возрождения

description: University Museums of Ukraine: the revival stage Liliya Kazantseva PhD, Kyiv National Taras Shevchenko University Young Section UMAC in Ukraine, which was created only in 2011, set a goal to change societal attitudes towards university collections for their conservation. To do this we are exploring the world experience to overcome the problems of volume, typology and current savings of academic heritage, the basic needs of museums. In addition, we pay much attention to promotion of university museums and their educational work, looking for partners for interdisciplinary research in the collections. By the beginning of 2012 a total of 495 museums and collections housed in 147 educational establishments in Ukraine had been mapped. Just 96 of these also cover the history of the educational establishments, and only 180 have their own websites. The museums are also trying to raise the level of education of employees who are dealing with collections. Unfortunately, because we are confronted with mistrust, we have to unite ourselves as many preserved collections have the sad experience from the past with the collections of regional museums being scattered and most valuable exhibits removed from regional museums to the central museums. We hope that we will overcome temporary difficulties in the future and the collections of unique national university will become more accessible, understandable and useful not only to the Ukrainian community, but also the world community. It is important for a museum or collection to be widely known and frequented and influential because a combination of these factors makes its status more secure. And we have much to be proud of – the history of education in Ukraine dates back over a thousand years. Contact with Estonia and the University of Tartu dates back at least two hundred years.

description: The $AB_{N-1}$ chain is a system that consists of repeating a unit cell with $N$ sites, where between the $A$ and $B$ sites there is an energy difference of $λ$. We considered bosons in these special lattices and took into account the kinetic energy, the local two-body interaction, and the inhomogenous local energy in the Hamiltonian. We found the charge density wave (CDW) and superfluid and Mott insulator phases, and constructed the phase diagram for $N=2$ and $3$ at the thermodynamic limit. The system exhibited insulator phases for densities $ρ=α/N$, with $α$ being an integer. We obtained that superfluid regions separate the insulator phases for densities larger than one. For any $N$ value, we found that for integer densities $ρ$, the system shows $ρ+1$ insulator phases, a Mott insulator phase, and $ρ$ CDW phases. For non-integer densities larger than one, several CDW phases appear.
