description: We study the motion of pedestrians through an obscure tunnel where the lack of visibility hides the exits. Using a lattice model, we explore the effects of communication on the effective transport properties of the crowd of pedestrians. More precisely, we study the effect of two thresholds on the structure of the effective nonlinear diffusion coefficient. One threshold models pedestrians's communication efficiency in the dark, while the other one describes the tunnel capacity. Essentially, we note that if the evacuees show a maximum trust (leading to a fast communication), they tend to quickly find the exit and hence the collective action tends to prevent the occurrence of disasters.

description: Door from the front of the old university building? Egle Tamm, MA, Tartu City Government, Cultural Values Service The door discussed in the article served as the entrance to the building at Jaama Street 27 until 2000. The article examines the possibility of this door coming from the old building of the University of Tartu on Town Hall Square (Town Hall Square 6/Rüütli Street 6). The old university building was initially (late 18th century) constructed as a residential building, hence its appearance was not that of a grand temple of knowledge. The university purchased it in 1802, the year it was re-opened. An order was placed for an academically-themed entrance door to add appropriate and immediately visible meaning to the new content of the building – to demonstrate the boundary between the academic world and the mundane life of the city. Both door wings had a reliefed profile of a male head in the middle. The head on the left depicted an older man with a beard, slightly curled hair and a fringe. The head on the right side depicted a younger man with no beard, but again with slightly curled hair and a fringe. Generally speaking these two profiles should be interpreted as the professor and his student. This new iconography was based on typical antique male head styles: with curled hair and a fringe, younger men clean-shaven and older men bearded. The large university building by the market was referred to as the academic house or simply the academy, this reference harking back to the school of philosophy founded by Plato in Athens in the 4th century BC. This is why we can also assume that the two male heads on the door are Plato (who died in 347 BC) and Aristotle (384-322 BC), the most famous mentor/disciple pair of antiquity. Semantically this was a precise and suitable symbol for an academic building as it expressed the philosophical trends and the thoughts prevalent in that epoch. It is currently impossible to date the door. The timeframe in which the door could have been made starts in 1797 and ends in 1840. The most likely time is the first decade of the 19th century. The door was removed from the old university building at some point between the 1840s and the 1870s, probably when the building was no longer used for humanities, being allocated instead to the pharmaceutical institute. It is likely that the door was then installed in the building at Jaama Street 27.

MICROBIAL SOURCE TRACKING FOLLOWING EXTREME FLOODING IN AREAS OF DENSE SWINE PRODUCTION

description: Storm events are expected to increase with climate change and can present challenges to wastewater infrastructure including outdoor waste lagoons associated with food animal production facilities. We examined different land uses and their effect on the presence of host specific markers and antibiotic resistance Salmonella after a natural disaster. Using qPCR and antibiotic resistance testing we compared surface water sites proximal to swine confined animal feeding operations (CAFOs) and background sites and compared their microbial water quality after Hurricane Florence. We found that watersheds with swine CAFOs had a higher concentration of the swine-associated marker Pig-2-Bac, and a higher concentration of multi- drug resistant Salmonella compared to background sites. These results suggest that better infrastructure for managing swine manure may be needed, especially in areas prone to natural disasters, to limit fecal contamination of water resources and to prevent dissemination of antibiotic resistant bacteria.

description: The first Tartu Student Days owe a lot to the sports complex in Kääriku and the KVN show Toomas Alatalu Feodor Klement, Rector of the University of Tartu, and the university lecturers and students were all audaciously eager to use the “thaw” period in the Soviet regime’s policies following the revelations about Stalin’s personality cult and so they used the World Festival of Youth and Students in Moscow in 1957 as a pretext to organise in Tartu the Baltic Students’ Song Festival in the same year. As the political “thaw” peaked for the second time, the students became more politically minded and active and this development was called the “Tartu spirit”, denoting opposition to official politics and submission of proposals aimed at reforming the system. On the students’ initiative a circle on international relations and a sociology circle were established in 1963-64. The humour/skits competition format borrowed from the highly popular Soviet Central Television show called KVN (this Russian abbreviation stands for the “Club of the Merry and the Inventive”) and the public political debates allowed the students to discover a feeling of empowerment. Thus the idea took shape of organising special days for all students. The first such student days took place in October 1965 and the key motif of the event was removal of all the bad things from the university and from the city itself: thousands of students participated in the mock funeral of the “boring professor” and the “lazy student”. The university’s Young Communist League leaders, including Karl Adamson, Toomas Alatalu, Priit Järve, Jaak Kaarma and Mikk Titma, displayed a daring approach that engaged youth leaders in most cities and districts of Estonia. As a result, in February 1966 the XIII Congress of the Estonian Leninist Young Communist League approved the alternative action plan drawn up in Tartu for the purpose of enhancing youth rights and voted against the Central Committee Secretary sent from Moscow. At the university’s Young Communist League Conference in April 1966 a proposal was put forward to reduce to a minimum the volume of teaching of the doctrine of the Communist Party of the Soviet Union. The demand was made and met to increase tenfold the allocation of trips abroad to the students. These were the highest achievements of the Estonian student members of the Young Communist League who were oriented towards the stance taken by young people in Poland and Czechoslovakia. Moscow then implemented direct party control over Young Communist League activities, culminating in the relegation of the Tartu Student Days to the level of an official ideology tool in 1970.

description: Food processors spent nearly 5 cents for fuel per each dollar of value added by manufacture in 1977--double the amount spent in 1972 and 1967. This study suggests that measuring energy costs as a percentage of the value added by production or manufacture and as a percentage of labor and management earnings may be better than the commonly used measurement of energy costs as a percentage of cash sales or expenses.

description: In the real world, many complex systems are represented not by single networks but rather by sets of interdependent ones. In these specific networks, nodes in one network mutually interact with nodes in other networks. This paper focuses on a simple representative case of two-layer networks (the so-called duplex networks) with unidirectional inter-layer couplings. That is, each node in one network depends on a counterpart in the other network. Accordingly, the former network is called the response layer and the latter network is the drive layer. Specifically, synchronization between each node in the drive layer and its counterpart in the response layer (counterpart synchronization, or CS) of this sort of duplex networks with delayed nodes and noise perturbation is investigated. Based on the LaSalle-type invariance principle, a control technique is proposed and a sufficient condition is developed for realizing counterpart synchronization of duplex networks. Furthermore, two corollaries are derived as special cases. In addition, node dynamics within each layer can be various and topologies of the two layers are not necessarily identical. Therefore, the proposed synchronization method can be applied to a wide range of multiplex networks. Numerical examples are provided to illustrate the feasibility and effectiveness of the results.

description: The First Articles of Association of Livonian Public Welfare and Economic Society and its Ideological Sources In the autumn of 1795 Georg Friedrich Parrot, a young scientist, joined the Livonian Public Welfare and Economic Society (LS), and was soon appointed its secretary of science. Parrot started to develop the activity programme of the LS that evolved into the organisation’s first articles of association. Parrot’s main points included, among others, the improvement of the natives’ situation, facilitating their education and bettering their living conditions. Those proposals were worded as main purposes in the style of the French physiocrats, intended to guarantee the development of the society in its entirety, in the spirit of the Age of Enlightenment. The physiocratic principles worded by Parrot had a role in the emancipation of Estonian and Latvian peasants in the early 19th century. It is also interesting to view the visual output of the purposes set by Parrot and his fellow thinkers, realized by Johan Wilhelm Krause, who worked as a tutor in the home of Ludvig August Mellin, a founding member of LS. His designs reflect several ideological directions in creating the symbols of the future LS – one that pointed to the French enlightened thinkers, and other that relied on ancient authors and underlined the paternalistic care that the estate owner provided to the peasants. It is most likely significant that in the early 19th century the diploma of the LS was developed from the latter, which was probably not in accordance with Parrot’s programme.

description: In this article we show the convergence of a loop ensemble of interfaces in the FK Ising model at criticality, as the lattice mesh tends to zero, to a unique conformally invariant scaling limit. The discrete loop ensemble is described by a canonical tree glued from the interfaces, which then is shown to converge to a tree of branching SLEs. The loop ensemble contains unboundedly many loops and hence our result describes the joint law of infinitely many loops in terms of SLE type processes, and the result gives the full scaling limit of the FK Ising model in the sense of random geometry of the interfaces. Some other results in this article are convergence of the exploration process of the loop ensemble (or the branch of the exploration tree) to SLE$(κ,κ-6)$, $κ=16/3$, and convergence of a generalization of this process for $4$ marked points to SLE$[κ,Z]$, $κ=16/3$, where $Z$ refers to a partition function. The latter SLE process is a process that can't be written as a SLE$(κ,ρ_1,ρ_2,\ldots)$ process, which are the most commonly considered generalizations of SLEs.

This allows us to discuss the semiclassical effective dynamics of the quantum universe, which resembles that of LQC. In particular, the regulator is identified with the third root of the inverse number of nodes within each homogeneous patch, while inverse-volume corrections are enhanced.

Spin susceptibility and effects of inhomogeneous strong pairing fluctuations in a trapped ultracold Fermi gas

description: We theoretically investigate magnetic properties of a unitary Fermi gas in a harmonic trap. Including strong pairing fluctuations within the framework of an extended $T$-matrix approximation (ETMA), as well as effects of a trap potential within the local density approximation (LDA), we calculate the local spin susceptibility $χ(T,r)$ above the superfluid phase transition temperature $T_{\rm c}$. We show that the formation of preformed singlet Cooper pairs anomalously suppresses $χ(T,r)$ in the trap center near $T_{\rm c}$. We also point out that, in the unitarity limit, the spin-gap temperature in a uniform Fermi gas can be evaluated from the observation of the spatial variation of $χ(T,r)$. Since a real ultracold Fermi gas is always in a trap potential, our results would be useful for the study of how this spatial inhomogeneity affects thermodynamic properties of an ultracold Fermi gas in the BCS-BEC crossover region.

description: Dark matter detectors with directional sensitivity have the capability to distinguish dark matter induced nuclear recoils from isotropic backgrounds, thus providing a smoking gun signature for dark matter in the Galactic halo. Motivated by recent progress in graphene and two-dimensional materials research, we propose a novel class of directional dark matter detectors utilizing graphene-based van der Waals heterostructures. A conceptual design of the detector based on graphene/hexagonal boron nitride and graphene/molybdenum disulfide heterostructures is developed and analyzed. The proposed detector has modular scalability, keV-scale detection threshold, nanometer position resolution, sensitivity down to 10 $\mathrm{GeV}/c^2$ dark matter mass, and intrinsic head-tail discrimination and background rejection capabilities.

description: We predict an existence of an new dissipation channel leading to attenuation of ultrasound in disordered conductors and superconductors with perfect electroneutrality. It is due to slow diffusion of thermal energy. We show that in doped silicon ultrasound attenuation may be enhanced by a factor about 100. Similar effect is also studied for s-wave and d-wave superconductors. The latter case is applied to BSCCO family where strong enhancement of ultrasound attenuation is predicted. For usual s-wave superconductors new dissipation channel might be important for very low-electron-density materials near the BCS-BEC crossover.

Jannseni Eesti Põllumees (1868-1880)
Creators: name: Salupere, Malle
Publisher: name: Tartu Ülikooli ajaloo küsimusi
Year: 2013

description: Jannsen’s “Eesti Põllumees” (1868-1880) Johan Voldemar Jannsen holds a special role in the cultural history of Estonia — until 1875 the vast majority of Estonian periodicals were founded by Jannsen. Perno Postimees (1857–1863) and Eesti Postimees (1864–1880) that he edited were responsible for all the explanation and organisation work during the national awakening. Jakobson’s newspaper “Sakala” did not come into circulation until only 1878, while it took over all Jannsen’s subjects but wrote of them in a sharper manner. Greatly to him do we owe the myth of his competitor Jannsen’s turncoat nature. Jannsen did receive support from the Estonian and Livonian knightage and Society in 1870–1879 but this was first and foremost connected to the gentry’s attempts to present themselves as a supporter of the native’s cultural endeavours in the eyes of the locals and administration. In addition to the song festival and the organisation of song and music societies Jannsen attempted to found agricultural societies for the development of farmers’ skills and knowledge, while he also established a respective journal—Eesti Põllomees—that was published as a monthly supplement to the Baltische Wochenschrift, a journal issued by the Society. Hermann v. Samson, a versatile and difficult man, who organised support for Jannsen’s publications in Livonia and Estonia, was the official editor and most likely also the censor of the journal for the first half-year (1869). The newspaper was published on the first day of every month, the content was quite versatile and the illustrations in the style of wood engraving (author: Eduard Magnus Jakobson). The Society supported the publication with both subscriptions and financial contributions. The newspaper introduced practical methods of agriculture and animal husbandry, using manure and artificial manure, tending pastures, construction of farmhouses, nature protection issues, often in the form of a dialogue with the exemplary farmer Tiit from the farm of Niidu. After some time the content and regularity of publication of the newspaper began to decline. Jannsen bowed out from editing the paper in 1877, Põllumees transferred to the ownership of agricultural societies and was published regularly at first, providing accounts of the activities of the societies. However, already the next year ended with only a double issue (5/6) having been published and in 1879, no new issues came. In 1880 Jannsen commented that Põllumees had so to say returned to its father and the journal was published twice a month as a supplement of the Eesti Postimees. At the end of the year Jannsen had a stroke and both Eesti Postimees as well as Põllumees went into decline. The last issue of the Põllumees was published in early 1889.

description: Excerpts from the Foreword: An economic program of agricultural production that will contribute substantially to agricultural betterment must cope with three major problems: (1) The adjustment of supplies both in quantity and quality to world competition and market requirements, (2) increasing efficiency in production and resulting lower costs of production, and (3) the elimination of submarginal land from cultivation and the maintenance of an economic balance between agriculture on the one hand and other economic activities on the other. In the following brief summary the authors present, graphically and in a simple way, some of the high lights of existing conditions and tendencies in the use of land. No attempt is here made to formulate a concrete and specific policy of land utilization. The essential elements in such a policy are perhaps fairly well established, but there are many questions still to be answered. Are low farm incomes, tax delinquency, and farm abandonment in particular areas due to hopeless handicaps or can agriculture be restored through some form of reorganization? What lands now in farms are best adapted to supply the requirements of future agricultural expansion and under what conditions of utilization? What lands not adapted to crop production can be profitably reforested by private enterprise? What lands not adapted to crop production or to reforestation through private effort could advantageously be acquired by the public? We need a land policy that will yield greater economic and social values from the use of our lands, and at the same time stay soil erosion and wasteful depletion of our natural resources. The Nation should replace without further delay the present policy of planless agricultural development with a program of research, education, and legislation that will facilitate essential adjustments in our agriculture and help to eliminate submarginal lands from the production of crops.

The points are supposed independently randomly generated on a domain $Ω\subset\mathbb R^d$ with a given distribution $ρ(\mathbf x)$ on $Ω$. In particular, we derive a general expression for the correlation function and for the average optimal cost of the optimal matching. A previous ansatz for the matching problem on the flat hypertorus is obtained as particular case.

description: Livonian Public Welfare and Economic Society through the Eyes of an Archivist An extensive amount of materials is kept in the Estonian Historical Archives on the activities of the Livonian Public Welfare and Economic Society, its branches and affiliates; the materials have been widely used in the research on the Society. The fields of activity of the Society that have been more thoroughly researched are animal husbandry and breeding, forestry, land improvement, 19th century peasant reforms, and cartography. A number of articles and research papers on the various fields of activity of the Society have been published. At the same time, collections still retain quite a few archival documents that have not thus far engaged the attention of any researcher. Working through the Society’s correspondence systematically and thoroughly would probably take years but even a brief acquaintance with the fund documents proves to show that the material is versatile. The Society was a place where people turned to with a range of problems to receive advice, aid, and support. Thus, the surviving correspondence offers illimitable opportunities for finding material pertaining to individual questions from various walks of life, be they attempts of fertilizing fields with guano, new roofing materials, insuring animals or people, organising agricultural education, constructing waterways, and a thousand subjects more. There are subjects that are constantly present, e.g., construction of waterways or insurance issues. Some questions are discussed only once or twice, e.g. using wild chestnuts for feed, eye problems of the peasants, etc. The Society’s files from 1914–1918 are also interesting and would certainly offer more detailed information on, for example, the everyday life in Tartu during WW I. The plans and drawings in the files possess an individual value. In addition to the numerous plans on constructing waterways and channels, one is able to view the plan of the Tartu postal station and its location, and different example plans of domestic buildings. The archive of the Society is rich in publications. Since the Society had connections with many organisations, societies and institutions, the subjects of the publications are from very different walks of life. During the writing of this article, data on 400 publications was entered into the archive’s library catalogue URRAM while reviewing archive documents. Seven of the publications had no entry in the Estonian national bibliography.

description: The Livonian Public Welfare and Economic Society and Studies in the Estonian Relief in the 19th Century It is remarkable that the history of Estonian cartography is at the same time the history of Estonian agriculture, not that of military sciences with which the development of cartography is usually connected in many countries of the world. Military science did have a roll in mapping the western governorates of Russia, i.e., Estonia, Livonia and Courland, but the Estonian, Livonian and Curonian agricultural societies were more important in the early 19th century and its second half. The first detailed hypsographic map in Estonia was completed upon the initiative of the Estonian Agricultural Society in the years 1868–1869 with the purpose of determining the paludified areas in the governorate of Estonia. The Livonian Public Welfare and Economic Society did not want to fall behind its sister organisation. Carl Johann von Seidlitz, owner of the Meeri estate, physician and naturalist, was responsible for the general levelling of Livonia from the part of the Society. He headed the respective commission which determined the main principles of levelling by early 1874 and tasked that the measurements to be taken be more precise than in Estonia. They did achieve that purpose, although the work was prolonged and financially exhausting for the Society.

description: Ingliskeelne õppetöö Eesti rahvusülikoolis: üleilmastumine toetab järkjärgulist muutumist Virve-Anneli Vihman, Ülle Tensing Tartu Ülikool Käesolev ülevaateartikkel kirjeldab inglise keele kui õppekeele kasutamist Tartu Ülikoolis alates Eesti Vabariigi taasiseseisvumisest. Artikli esimeses pooles antakse kokkuvõtlik ülevaade ingliskeelsete ainekursuste ja semestriprogrammide loomisest 1990. aastatel. Artikli teine pool kirjeldab sellele järgnenud sotsiaalseid, poliitilisi ja hariduskorralduslikke muudatusi hõlmavat perioodi, mis mõjutas ülikoolis ingliskeelsete õppekavade kujunemise esimest etappi, aastatel 2005–2011. Artiklis heidetakse pilk Tartu Ülikooli rahvusvahelistumise hoogustumisele ja peatutakse küsimusel, kuidas keelepoliitika dokumentides ja ühiskonnas toimuvates aruteludes on käsitletud inglise keele rolli suurenemist viimase kahekümne aasta jooksul. Artikli autorid leiavad, et ülikooli akadeemilise ja tugipersonali hoiakud, põhimõtted ja tegevuste ulatus on oluliselt muutunud võrreldes ingliskeelse õppe arenduse esimese etapiga. Ingliskeelne õpe on jõudnud teise etappi, kus selle osakaal ülikooli õppetöös kasvab märgatavalt kiiremini ja see on suunatud kõigile õppijatele, mitte üksnes välisüliõpilastele. Kasvav kokkupuude välisüliõpilastega ja paremad võimalused kaasata välisõppejõude on andnud tõuke ingliskeelse õppe väärtustamisele teiste akadeemilist keskkonda mõjutavate eesmärkide kõrval, nagu õpetamisoskuste arendamine ja teadustegevuse konkurentsivõime suurendamine. Nii ülikoolis kui ühiskonnas arutatakse selle üle, millist mõju avaldab ingliskeelne õppetöö eestikeelsele haridusele ja teadusele ning kuidas parandada ja tagada inglise keeles toimuva õppetöö kvaliteeti. Arutelude lähemal uurimisel on näha, et inglise keele osatähtsuse kasv ärgitab tuliseid sõnavõtte ja hoiakud õppekeelte mitmekesisuse suhtes on vastandlikud. On oluline, et avalikud arutelud eesti ja inglise keele kasutusest ja nende tasakaalust Eesti kõrghariduses jätkuvad ka ingliskeelse õppe teises etapis, mida iseloomustab selle keele oluliselt ulatuslikum kasutamine õppetöös eesti keele kõrval.

description: Lyman alpha blobs (LABs) are spatially extended lyman alpha nebulae seen at high redshift. The origin of Lyman alpha emission in the LABs is still unclear and under debate. To study their heating mechanism(s), we present Australia Telescope Compact Array (ATCA) observations of the 20 cm radio emission and Herschel PACS and SPIRE measurements of the far-infrared (FIR) emission towards the four LABs in the protocluster J2143-4423 at z=2.38. Among the four LABs, B6 and B7 are detected in the radio with fluxes of 67+/-17 microJy and 77+/-16 microJy, respectively, and B5 is marginally detected at 3 sigma (51+/-16 microJy). For all detected sources, their radio positions are consistent with the central positions of the LABs. B6 and B7 are obviously also detected in the FIR. By fitting the data with different templates, we obtained redshifts of 2.20$^{+0.30}_{-0.35}$ for B6 and 2.20$^{+0.45}_{-0.30}$ for B7 which are consistent with the redshift of the lyman alpha emission within uncertainties, indicating that both FIR sources are likely associated with the LABs. The associated FIR emission in B6 and B7 and high star formation rates strongly favor star formation in galaxies as an important powering source for the lyman alpha emission in both LABs. However, the other two, B1 and B5, are predominantly driven by the active galactic nuclei or other sources of energy still to be specified, but not mainly by star formation. In general, the LABs are powered by quite diverse sources of energy.

description: On language choices among Estonian doctoral students Eve-Liis Roosmaa, Triin Roosalu, Peep Nemvalts Tallinn University To explain language choices in Estonian doctoral theses we conducted a survey on the views of doctoral students regarding the usage of Estonian language in research and how this relates to their attitudes towards the usage of English language. We rely on the concept of intercultural strategies, introduced by John Berry (1997) as an extension of his earlier concept of acculturation strategies. In our study we consider Estonian doctoral students as members of small Estonian language research community embedded in large albeit diverse English language academic culture. We also assume that integration with academic world presumes in addition to understanding and knowledge building in English, wish to understand and express scientific thoughts in Estonian too. It appears that doing research in Estonian poses difficulties because doctoral students, especially those in natural sciences as compared to social sciences, cannot find right terms or concepts. However, doctoral students feel that scientific writing is easier, more logical and nuanced in mother tongue. Still, more than third of all respondents admit having problems with sentence construction. We find that doctoral students who have practiced different ways of doing science in Estonian (reading, writing, attending conferences), tend to assess their languages skills better. These are more likely social sciences doctoral students, as their research topics more often relate to studying Estonian specificity and thus overall scientific communication in Estonian is more intense in this field. Hence we find that doctoral students need systematic support in developing academic language in both Estonian and a foreign (often English) language.

Can prediction-based distributional semantic models predict typicality?
Creators: name: Heyman, Tom

Year: 2022
Subjects: subject: distribributional semantics
subject: predictive models
subject: typicality

description: Recent advances in the field of computational linguistics have led to the development of various prediction-based models of semantics. These models seek to infer word representations from large text collections by predicting target words from neighboring words (or vice versa). The resulting representations are vectors in a continuous space, collectively called word embeddings. Although psychological plausibility was not a primary concern for the developers of predictive models, it has been the topic of several recent studies in the field of psycholinguistics. That is, word embeddings have been linked to similarity ratings, word associations, semantic priming, word recognition latencies, etcetera. Here, we build on this work by investigating category structure. More specifically, we first obtained a prototype for a number of common categories (e.g., birds, fruit, vehicles,...) either by averaging across exemplar vectors (e.g., robin, dove, sparrow,...) or by relying on the representation of the label itself (e.g., bird). Then, we correlated the cosine similarity between an exemplar and its prototype with human typicality judgments. The resulting correlations turned out to be disappointingly low, especially given the enthusiasm surrounding predictive models.

description: To determine immune response to acute moderate-intensity aerobic exercise in breast cancer (BrCa) survivors compared with healthy controls. 15 sedentary females were age-matched to 21 BrCa survivors and performed 30 minutes of intermittent exercise at 60% wattage achieved at VO2peak. Hematological data was obtained, and immune cells were isolated from whole blood samples at rest and following exercise. All leukocyte populations significantly increased from pre to immediately post-exercise (P < 0.001) and returned to baseline values 1-hour post-exercise (P < 0.001). Exercise and recovery patterns from leukocytes, leukocyte subsets, and plasma volume shifts were similar between groups, except lymphocyte counts, which were significantly higher in controls (P < 0.001). BrCa survivors displayed similar immune responses to 30 minutes of moderate-intensity exercise to that of physically similar women without a history of cancer diagnosis. Although the results of this study are preliminary, they support findings from previous exercise immune-oncology studies.
