description: Perivascular epithelioid cell tumors (PEComas) form a family of rare mesenchymal neoplasms that typically display myomelanocytic differentiation. Upregulation of mTOR signaling due the inactivation of TSC1/2 (Tuberous Sclerosis 1 and 2) is believed to be a key oncogenic driver in this disease. Recently, a subgroup of PEComas harboring TFE3 (Transcription Factor E3) rearrangements and presenting with a distinctive morphology has been identified. TSC1/2 and TFE3 aberrations are deemed to be mutually exclusive in PEComa, with two different pathogenic mechanisms assumed to lead to tumorigenesis. Here, we challenge this dichotomy by presenting a case of a clinically aggressive TCS1-mutated PEComa displaying a TFE3-altered phenotype. FISH analysis was suggestive of a TFE3 inversion; however, RNA and whole genome sequencing was ultimately unable to identify a fusion involving the gene. However, a copy number increase of the chromosomal region encompassing TFE3 was detected and transcriptome analysis confirmed upregulation of TFE3, which was also seen at the protein level. Therefore, we believe that the TSC1/2-mTOR pathway and TFE3 overexpression can simultaneously contribute to tumorigenesis in PEComa. Our comprehensive genetic analyses add to the understanding of the complex pathogenic mechanisms underlying PEComa and harbor insights for clinical treatment options.

description: The myelocytomatosis oncogene (MYC) is an important driver in a subtype of pancreatic ductal adenocarcinoma (PDAC). However, MYC remains a challenging therapeutic target; therefore, identifying druggable synthetic lethal interactions in MYC-active PDAC may lead to novel precise therapies. First, to identify networks with hyperactive MYC, we profiled transcriptomes of established human cell lines, murine primary PDAC cell lines, and accessed publicly available repositories to analyze transcriptomes of primary human PDAC. Networks active in MYC-hyperactive subtypes were analyzed by gene set enrichment analysis. Next, we performed an unbiased pharmacological screen to define MYC-associated vulnerabilities. Hits were validated by analysis of drug response repositories and genetic gain- and loss-of-function experiments. In these experiments, we discovered that the proteasome inhibitor bortezomib triggers a MYC-associated vulnerability. In addition, by integrating publicly available data, we found the unfolded protein response as a signature connected to MYC. Furthermore, increased sensitivity of MYC-hyperactive PDACs to bortezomib was validated in genetically modified PDAC cells. In sum, we provide evidence that perturbing the ubiquitin-proteasome system (UPS) might be an option to target MYC-hyperactive PDAC cells. Our data provide the rationale to further develop precise targeting of the UPS as a subtype-specific therapeutic approach.

description: In 2020, the University of Tartu celebrated the 250th anniversary of the birth of Johann Karl Simon Karl Morgenstern, the first director of the University of Tartu/Dorpat Art Museum, which was founded in 1803. At first, the museum was housed in Morgenstern’s apartment at Town Hall Square, but in 1809 it was relocated to the newly erected main building of the university, to two rooms facing onto the street and next to the assembly hall. In 1839, Morgenstern drew up an inventory list for the museum. While the document adds little new knowledge about the history of the museum, it is important in helping us remember that the art museum has not always looked like it does today, complete with a colourful interior with Pompeii-style murals and white plaster copies of classical sculptures. Compared to the transforming and evolving museum spaces all over the world, the University of Tartu Art Museum has remained relatively unchanged over the past 150 years, but before that, the museum had a completely different appearance. The keywords describing the museum’s interior and collections in the first half of the 19th century are engravings and cabinets containing large prints as well as collections of coins and plaster casts of coins and gems packed in boxes, complemented by colourful ancient vases and Egyptian antiquities, as well as two mummies. The furniture from that time is still used in the museum. Some of the atmosphere of the Morgenstern-era art museum was brought back to life with the exhibition Morgenstern 250. The Enchanting Art of Glyptics, which was available to the public from June 2020 to March 2021.

Effective masses of electrons range from 6 to 18$m_e$, $m_e$ being the free electron mass. Remarkable discrepancies between the calculated and observed Fermi surface areas and the large mass enhancement ($\gtrsim 3$) highlight the importance of electronic correlations in determining the electronic structures of iron pnicitide superconductors.

Density profiles and density oscillations of an interacting three-component normal Fermi gas
Creators: name: De Silva, Theja N.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: We use a semiclassical approximation to investigate density variations and dipole oscillations of an interacting three-component normal Fermi gas in a harmonic trap. We consider both attractive and repulsive interactions between different pairs of fermions and study the effect of population imbalance on densities. We find that the density profiles significantly deviate from those of non-interacting profiles and extremely sensitive to interactions and population imbalance. Unlike for a two-component Fermi system, we find density imbalance even for balanced populations. For some range of parameters, one component completely repels from the trap center giving rise a donut shape density profile. Further, we find that the in-phase dipole oscillation frequency is consistent with Kohn's theorem and other two dipole mode frequencies are strongly effected by the interactions and the number of atoms in the harmonic trap.

Some aspects of approximation and computation for Bayesian inference
Creators: name: Efstathiou, Maria
Publisher: name: Imperial College London
Year: 2021

description: This thesis studies efficient integration techniques for implementation in Bayesian inference. Specifically, analytic, computational and hybrid methods are considered, in order to obtain accurate approximations of posterior moments or marginal distributions of parameters of interest, when nuisance parameters are present. Analytic techniques play an important role in this area and a large part of this work is concerned with their application. The main methods considered are Laplace’s method for the approximation of marginal posterior densities and posterior expectations and approximations based on asymptotic expansions of signed roots of log-density ratios. A method for deriving a likelihood for a single parameter of interest, in the presence of nuisance parameters, based on inversion of confidence intervals, is also explored. Sufficient conditions under which Laplace approximations to marginal posterior densities yield exact answers are identified and these are applied in the case of natural exponential families with cuts. Computational methods and in particular the importance sampling and sampling-importance resampling algorithms are considered in conjunction with analytic methods, the results from the latter being used as starting points for the former. The aim of these hybrid schemes is to improve the accuracy of the analytic approximations on one hand and the efficiency of the sampling algorithm on the other. A further part of the thesis is concerned with the development of methods for the numerical evaluation of reference distributions. The theoretical background of reference analysis is outlined and the difficulties in its implementation illustrated. A sampling-based approach is adopted for the numerical approximation of reference distributions. The effect of reparameterizations in the accuracy and efficiency of these approximation methods is investigated throughout this work.

description: From 1930ies the graduates of Soviet facilities of higher education were appointed mandatorily for five years to employments prescribed by the state. In 1948 this period was diminished to three years. The process of distributing „young specialists“ was to be run by the universities and institutes themselves, an obligation demanding a lot of administrative energy. In 1946 the practice was introduced also in Estonia. Here under special scrutiny occurred the medical profession, as the Soviet state had grand plans concerning the rearrangement of the public health system of this recently annexed territory. The practice of mandatory appointment included controversies – on one hand there were positions and locations preferred by the graduates and on the other there were these preferred by the state. During the more than 40 years during which the system of mandatory appointments existed, the state practiced different methods to succumb the graduates under its will. These extended from the draconic measures taken during the Stalinist era to the rather loose atmosphere in the final years of the Soviet Empire. The practice ended in 1990 during the era of Perestroika.

Who's Agency? A Study of Burial Murals in Ancient China
Creators: name: Chen, Pengpeng
Publisher: name: The Ethnograph: Journal of Anthropological Studies
Year: 2023

description: After Chinese tombs shifted from vertical shaft tombs to horizontal chamber tombs, murals became popular to decorate burial chambers. The subjects of these murals usually include portraits of the living, as well as the universe, gardens, and landscapes of imaginary spaces. Past studies of tomb murals have been limited to the dualism of the living and the dead, suggesting that mural paintings were a reflection of wealth and status. This paper, however, proposes that Chinese tomb murals should not be limited to a single perspective of living or deceased, but should be restored in conjunction with the theme of the murals and the construction process of the tomb.

description: INTEGRAL monitoring of the Galactic Plane in the last 5 years revealed a new subclass of High Mass X-ray Binaries (HMXBs), the Supergiant Fast X-ray Transients (SFXTs). They display flares lasting from minutes to hours, with peak luminosity of 1E36-1E37 erg/s and a frequent long term flaring activity reaching an X-ray luminosity of 1E33-1E34 erg/s, as recently detected by the Swift satellite. The quiescent level is around 1E32 erg/s. We performed a systematic re-analysis of archival INTEGRAL data of four SFXTs: IGRJ16479-4514, XTEJ1739-302, IGRJ17544-2619, IGRJ18410-0535. This led to the discovery of previously unnoticed outbursts from IGRJ16479-4514 and IGRJ17544-2619. We discuss these results in the framework of the different structure of the supergiant wind proposed to explain the outburst from this new class of sources.

Distribution and taxonomy of planktonic marine diatoms in the Strait of Georgia, B.C.
Creators: name: Shim, Jae Hyung
Publisher: name: University of British Columbia
Year: 2010

description: The primary objectives of this study were the identification and measurement of diatom genera and species making up the diatom communities in the plankton of the Strait of Georgia/Juan de Fuca Strait system, and factors influencing their distributional ecology. The planktonic diatom communities at depths of one, 25, 50, and 75 meters in the area were studied and measured over a fifteen month period. Measurements of environmental factors included temperature , salinity and algal nutrients such as phosphate, silicate, nitrate, nitrite and ammonia. Attempts were made to establish relationships between environmental factors measured and marine planktonic diatoms through the use of multiple regression analyses. The results indicate that the total abundances of diatom communities and the species population changes were strongly correlated with season and location parameters (in which the exact regulating parameters are unknown) as well as specific nutrient concentrations and hydrographic factors. Major influences on population distributions varied with the principal species responsible for the observed species successions. Two distinct distributional patterns in total diatom standing crop were observed in the study area. Maximum standing crops observed during spring and/or summer did not usually result in the depletion of critical nutrients (such as silicate, nitrate) to levels which might be growth limiting. In a few instances phosphorus concentration was undetectable. On a small scale, the distribution of total diatom standing crop was significantly correlated with both season/location factors and with hydrographic parameters. Vertical stratification of diatoms was observed only in the presence of the thermocline/halocline in the water column. The distribution of recurrent groups of diatoms was related primarily to the physical conditions. Within the study area there was some seasonal consistency in the composition of the species groups. There were radical changes in community structure with different seasons, as was expected. Two hundred and nineteen taxa have been identified as a results of light and scanning electron microscope observations. These taxa are attributed to 66 genera within 16 families. Of the total number of taxa three appear to be new species and five are new infraspecific taxa. Sixty-eight taxa are new records for western Canada. Some changes in the previous classification system were made using new information which has been accumulated through better technical facilities, especially through the scanning electron microscope. The diatom classification system used here was based on the present state of knowledege of diatoms and the author's own observations.

description: Excited states of Bose--Einstein condensates are considered in the semi-classical (Thomas-Fermi) limit of the Gross--Pitaevskii equation with repulsive inter-atomic interactions and a harmonic potential. The relative dynamics of dark solitons (density dips on the localized condensate) with respect to the harmonic potential and to each other is approximated using the averaged Lagrangian method. This permits a complete characterization of the equilibrium positions of the dark solitons as a function of the chemical potential parameter. It also yields an analytical handle on the oscillation frequencies of dark solitons around such equilibria. The asymptotic predictions are generalized for an arbitrary number of dark solitons and are corroborated by numerical computations for 2- and 3-soliton configurations.

description: Johann Karl Simon Morgenstern (1770–1852) was a Professor of Aesthetics, Rhetoric, Philology, and Art History at the University of Tartu/Dorpat. Besides coining the term Bildungsroman, Morgenstern was also a prolific art historian, creating and spreading knowledge about art. The reopening of the University of Tartu and Morgenstern’s deeds are a good example of the change in the knowledge regimes that occurred around 1800, where art played a crucial role (P. Burke, Circa 1808: Restructuring Knowledges. München; Berlin: Deutscher Kunstverlag, 2008, p. 50). From 1808 to 1810, Morgenstern travelled in Europe and later published some of his impressions from visiting various art galleries. In this article I focus on two of his texts: a booklet titled Über einige Gemälde (Of Some Paintings) from 1805 (K. Morgenstern, Über einige Gemälde. Dorpat: Universitätsbuchdrucker M. G. Grenzius, 1805), and a text about Raphael’s Transfiguration from 1822 (K. Morgenstern, Über Rafael Sanzio’s Verklärung. Dorpat: J. C. Schünmann; Leipzig: P. G. Kummer, 1822). I will analyse Morgenstern’s views in the context of Enlightenment ideas on art, and look at the proportion of knowledge and emotion present in his texts. Although Morgenstern’s main tool was description, he tried to provide some analysis as well, taking into consideration composition, characters, and anatomical correctness, for example. He wrote both about his contemporary artists and the Renaissance Masters. Morgenstern’s favourite was apparently Raphael, whom he admired greatly and to whom he devoted his longest texts. His emotions are the most unambiguously expressed namely in these writings where he shows Raphael as a true genius. It is also interesting how Morgenstern composed his longer texts. First, he described a picture as if he knew nothing about it. He viewed the expression of character through certain forms, such as hair or the folds of clothing. Second, Morgenstern identified and characterised the figures in a detailed manner. Third, he suggested parts of the picture held deeper symbolic meaning. He tried to show how the details of a painting contribute to its main emotion and emphasised how one has to look for and feel the influence of a painting, as it is hard to describe. In addition, Morgenstern gave a lot of thought to how his texts and the artworks (or their reproductions) would reach the audience. He emphasised the importance of viewing original artwork but worked diligently to mediate knowledge about it in his lectures at the university and his writings.

title: Studies on mouse gammaglobulins associated with Taenia crassiceps metacestodes
Creators: name: Morel, Anthony. M.
Publisher: name: The University of Edinburgh

Subjects: subject: Annexe MSc Digitisation Project 2022 Block 49
subject: Mouse gammaglobulins
subject: Taenia crassiceps metacestodes
subject: Immunoperoxidase technique
subject: DAS ELISA
subject: In vitro culture

description: The first objective of this project was to determine whether mouse gammaglobulins are associated with Taenia crassiceps metacestodes (Toi strain) removed from female CE1 mice and stored for up to eight weeks at l|°C, and to ascertain whether mouse gammaglobulins are detectable if the larvae are cultured in vitro at 37°C for eight days. The second was to show whether mouse gammaglobulins are detectable in the T. crassiceps metacestode in vitro culture medium. These evaluations were carried out using the immunoperoxidase technique with T. crassiceps metacestodes as the solid phase and the double antibody sandwich enzyme-linked immunosorbent assay (DAS ELISA) with T. crassiceps metacestode culture media as the test antigen. The immunoperoxidase tests using T_. crassiceps metacestodes were complicated by non-specific reaction between the rabbit antigoat garnmaglobul in conjugate and the metacestodes. ELISA tests were performed to show whether the non-specific reaction occurred between the conjugate and mouse serum products associated with the metacestodes. It was demonstrated that statistically significant amounts of mouse gammaglobulins were associated with T_. crassiceps metacestodes derived from female GF1 mice and stored for up to eight weeks at i|°C but that no statistically significant amounts of mouse gammaglobulin were detectable after the metacestodes had been cultured in vitro for eight days. Non-specific reaction was shown to occur between the rabbit anti—goat gammaglobulin conjugate and mouse serum products associated with T,. crassiceps metacestodes. Results from the DAS ELISA indicated that if T. crassiceps metacestodes were maintained in vitro culture at 37°C, significant amounts of mouse gammaglobulin could be detected in the culture medium collected two days after the culture was set up, but very little was detectable in the media collected I4, 6 and 8 days after culturing. It was concluded that this study provides evidence to suggest that mouse gammaglobulins are associated with mouse derived T. crassiceps metacestodes and that these gammaglobulins are liberated from the metacestodes when cultured in vitro at 37°C.

description: Densities of states for simple (sc) and base-centered (bcc) cubic lattices with account of nearest and next-nearest neighbour hopping integrals $t$ and $t'$ are investigated in detail. It is shown that at values of $τ\equiv t'/t = τ_\ast$, corresponding to the change of isoenergetic surface topology, the formation of van Hove $\bf k$ lines takes place. At small deviation from these special values, the weakly dispersive spectrum in the vicinity of van Hove lines is replaced by a weak $\bf k$-dependence in the vicinity of few van Hove points which possess huge masses proportional to $|τ- τ_\ast|^{-1}$. The singular contributions to the density of states originating from van Hove points and lines are considered, as well as the change in the topology of isoenergetic surfaces in the $\bf k$-space with the variation of $τ$. Closed analytical expressions for density of states as a function of energy and $τ$ in terms of elliptic integrals, and power-law asymptotics at $τ= τ_\ast$ are obtained. Besides the case of sc lattice with small $τ$ (maximum of density of states corresponds to energy level of X $\bf k$-point), maximal value of the density of states is always achieved at energies corresponding to \textit{inner} $\bf k$-points of the Brillouin zone positioned in high-symmetry directions, and not at zone faces.

description: We describe an experimental study of spin-projection noise in a high sensitivity alkali-metal magnetometer. We demonstrate a four-fold improvement in the measurement bandwidth of the magnetometer using continuous quantum non-demolition (QND) measurements. Operating in the scalar mode with a measurement volume of 2 cm^3 we achieve magnetic field sensitivity of 22 fT/Hz^(1/2) and a bandwidth of 1.9 kHz with a spin polarization of only 1%. Our experimental arrangement is naturally back-action evading and can be used to realize sub-fT sensitivity with a highly polarized spin-squeezed atomic vapor.

description: The foundation of the imperial University of Tartu/Dorpat has been described as being part of the rationalist Enlightenment movement, with a focus on the importance of the Rector and Professor of Physics Georg Friedrich Parrot, or Johann Wilhelm Krause (university architect and Professor of Architecture). Johann Karl Simon Morgenstern (director of the University Library and Museum, Professor of Rhetoric, Classical Philology, Aesthetics, Art History and History of Literature) has been studied from various aspects before, but his neo-humanist ideas have been mostly described from the perspective of classical scholarship. The goal of this paper is to review the sources of the humanist curricula of introductory subjects, which Morgenstern taught to all faculties during his activity, focussing on two examples. Friedrich August Wolf has often—with good reason—been described as Morgenstern’s main inspiration, but we also need to consider the influence of Julius Erduin Koch, whose Hodegetik offers recommendations for introductory subjects in all faculties. Almost all of these were taught by Morgenstern from 1803 to 1836.

The first accurate parallax distance to a black hole

description: Using astrometric VLBI observations, we have determined the parallax of the black hole X-ray binary V404 Cyg to be 0.418 +/- 0.024 milliarcseconds, corresponding to a distance of 2.39 +/- 0.14 kpc, significantly lower than the previously accepted value. This model-independent estimate is the most accurate distance to a Galactic stellar-mass black hole measured to date. With this new distance, we confirm that the source was not super-Eddington during its 1989 outburst. The fitted distance and proper motion imply that the black hole in this system likely formed in a supernova, with the peculiar velocity being consistent with a recoil (Blaauw) kick. The size of the quiescent jets inferred to exist in this system is less than 1.4 AU at 22 GHz. Astrometric observations of a larger sample of such systems would provide useful insights into the formation and properties of accreting stellar-mass black holes.

title: Studies on the fluorescent antibody test in the diagnosis of Toxoplasma gondii - induced ovine abortion

description: The work was carried out to look at a discrepancy between results from the immunofluorescent test and other diagnostic techniques in the diagnosis of Toxoplasma-induced abortion in lambs. Several Veterinary Investigation Centres, including the one at Edinburgh, had used the immunofluorsecent test for some years, but had become increasingly cautious in the interpretation of the results. An analysis of data accumulated by the Edinburgh Veterinary Investigation Centre was carried out to examine correlations between the immunofluorescent test, the indirect haemagglutination test and mouse inoculation. Toxoplasma was observed in sections of mouse tissues, using the immunofluorescent technique. This was followed by titration of test reagents using toxoplasmas as antigen, and, at the beginning of the lambing season, by titration using lamb spleen smear cells. The numbers and types of fluorescing spleen cells were examined both before and after counterstaining with Evan's blue. Finally, fluorescent spleen smear cells were examined after restaining with Giemsa and an attempt made to identify the cell types. Analysis of data revealed no correlation between results from the immunofluorescent test and those from serological and mouse inoculation techniques. The titration of reagents using Toxoplasma and spleen smear cells revealed that the fluorescence observed in the spleen cells could not be related to specific fluorescence caused by Toxoplasma. Further, spleen cells fluoresced under ultra-violet light without the addition of fluorescein-labelled conjugate. Although the fluorescing spleen smear cells appeared to be granular, attempts to identify them after restaining with Giemsa were unsuccessful. The conclusion is made that the immunofluorescent test described is not specific for Toxoplasma-induced ovine abortion.

description: We propose and test an algorithm to simulate a lattice system of interacting fermions in two spatial dimensions. The approach is an extension of the entanglement renormalization technique [Phys. Rev. Lett. 99, 220405 (2007)] and the related multi-scale entanglement renormalization ansatz. Benchmark calculations for free and interacting fermions on a lattice of $6\times 6$ sites and periodic boundary conditions confirm the validity of this proposal.
