Experimental and computational investigation of two-dimensional entities

description: Two-dimensional (2D) transition metal dichalcogenides and 2D entities (domain walls in 3D ferroelectric single crystals) were analysed throughout this work using a combination of experimental scanning transmission electron microscopy (STEM) techniques, and computational image simulation. Se implantation of molybdenum disulphide (MoS2) was investigated via high angle annular dark field (HAADF) STEM image simulation. Substitutional ions were accurately identified through comparison of experimental images with simulations. Further simulations of thicker 2D samples and various ion species found that as samples transition from thin to thick (from less than 1 nm to greater than 1 nm), the intensity margins become narrower. Simulation of different substitutional atoms found that image intensity can be similar between species, solidifying the need for spectroscopy to first identify all atomic species in the sample, before accurate simulations can be produced. Examination of 2D transition metal dichalcogenides (TMDCs) including MoS2, tungsten disulphide (WS2), and tungsten diselenide (WSe2), when deposited with various metals (gold, palladium, nickel), were completed via HAADF STEM under various conditions. Palladium exhibited different particle behaviour dependant on the substrate TMDC it was in contact with when heated ex-situ. The different behaviour suggests a difference in bonding dynamics. Pd-WSe2 was the most thermally stable pair, suggesting it would be a suitable bond to investigate for future metal-TMDC contacting. Nickel oxidised when left in the atmosphere, meaning unless nickel is put onto a TMDC under vacuum, and then encapsulated, it will oxidise immediately and be of little use for electrical contacting purposes. The nickel oxide particles had a size and shape independent of the 2D substrate beneath them, and the total nickel deposited amount. 4DSTEM was used to study the strain dynamics and properties of 2D WSe2 deposited with gold nanoparticles. A strain range of 7% was found, showing nanoparticles are an effective manner of creating regions of varying strain. Patterned deposition of nanoparticles may become a method to create regions of a different strain, tailoring regions with different electrical and optoelectrical properties in 2D TMDCs. 4DSTEM also found the strain in 2D domain walls in ferroelectric Cu3B7O13Cl to range between 0.4%. These minimal ranges show the mechanical strain induced in the material in its orthorhombic form. Changing the electron beam current resulted in domain walls moving to reduce internal stress caused by changes in charge carrier concentrations.

description: From the Library to Science and Researchers Development and Staff Members of the Department of Subject Librarians This is an overview of the work of the Department of Subject Librarians at the UT Library and their cooperation with the university in supporting teaching and research. Among the main tasks of the Department of Subject Librarians have for years been databases-related advisory activities, the selection of packages of databases and digital journals for subscription and the organisation of test periods for the packages. Tasks related to university teaching include the mediation of information about ordering publications, organisation of the deposition of publications to university subunits and the lending of materials to the university teaching staff, and the preparation of reserved course materials packs. Teaching of information literacy to university and gymnasium students is an important area of work. Since 2014, the department has been developing open science-related services, focussing on teaching research data management and consulting about data management plans. Another important field of activities includes user training and the raising of information knowledge awareness. Staff members developed an e-course for teaching information literacy for students. In cooperation with university institutes, the teaching of information literacy has been integrated into several curricula. Staff members of the department also participate in the creation of the Estonian Subject Thesaurus.

description: Part of a collection of correspondence from Kathleen Raine to Herbert Read. Raine was a British scholar and poet who was awarded the Queen’s Gold Medal for Poetry in 1992. The correspondence here follows Raine’s work on a book about William Blake’s mythology. Other topics include discussion of philosophical and metaphysical subjects, and references to acquaintances in literary and arts circles. In this letter Raine writes that she is still working to edit and shorten her William Blake manuscript, but vows that she will not leave Cambridge until the book is done. She also responds to Read's thoughts about metaphysical archetypes. At the end, Raine wonders how much of her Blake manuscript Read might disagree with.

description: The University of Tartu Library - the Flag-bearer of Open Science Activities of the University of Tartu Library in promoting open science were started with the introduction of the possibilities offered by open access (2009). During the recent decade, the library has become a leading open science activities-related institution in Estonia and a good partner for international organisations and projects. The Library has created a matrix management-based trans-departmental Open Science Work Group, which cooperates with other units within the university (Grant Office, the Centre for Ethics, ETAIS and HPC) and without (Ministry of Education and Research, Estonian Research Council, other universities). UT Library is a member of a number of international organisations engaged in open science activities, such as DataCite, RDA and COAR; the library is the OpenAIRE Estonian National Open Access Desk (NOAD). The library participates in many international projects (OpenAIRE, EOSC-Nordic, Enlight Rise). The main open science-related activities involve different ways of supporting the UT researchers. The library offers repositories for publishing research data and different publications, an open access publication platform, and possibilities for creating subject databases and using text analysis tools. Another important area of activities is the teaching of junior researchers and doctoral students. For this purpose, several e-courses on data management were created at the library. The most exhausting course „Research data management and publication” was developed in cooperation with the team of the data management platform PlutoF. This course was awarded the e-course quality label in 2020. Teaching of researchers is also the objective of international seminars held at the library once or twice a year, inviting best specialists in their field from different areas. Open science is advertised and marketed via a number of different channels – the UT Library web page, and the DataCite Estonia Consortium’s web page for data centres, researchers and partner universities. The Estonian Open Science policy is still under development, but it would be good if its main information channel were the web page and logo of Open Science. Ideally, it could be the brand for all Estonian open science activities, known and used by all.

Nonparametric Detection of Geometric Structures over Networks

description: Nonparametric detection of existence of an anomalous structure over a network is investigated. Nodes corresponding to the anomalous structure (if one exists) receive samples generated by a distribution q, which is different from a distribution p generating samples for other nodes. If an anomalous structure does not exist, all nodes receive samples generated by p. It is assumed that the distributions p and q are arbitrary and unknown. The goal is to design statistically consistent tests with probability of errors converging to zero as the network size becomes asymptotically large. Kernel-based tests are proposed based on maximum mean discrepancy that measures the distance between mean embeddings of distributions into a reproducing kernel Hilbert space. Detection of an anomalous interval over a line network is first studied. Sufficient conditions on minimum and maximum sizes of candidate anomalous intervals are characterized in order to guarantee the proposed test to be consistent. It is also shown that certain necessary conditions must hold to guarantee any test to be universally consistent. Comparison of sufficient and necessary conditions yields that the proposed test is order-level optimal and nearly optimal respectively in terms of minimum and maximum sizes of candidate anomalous intervals. Generalization of the results to other networks is further developed. Numerical results are provided to demonstrate the performance of the proposed tests.

description: Changes and Movements in the Development of the University of Tartu Library Collections in 2010–2021 Regarding collections development, the years 2010–2021 were characterised by constantly shrinking sums for the acquisition of library materials, leading to the reduction in the number of copies acquired and causing the cancellation of subscriptions, as well as bringing about the reduction in the volume of publications exchange with research libraries in abroad. All in all, the collections development activities were seriously restricted by the scarcity of the acquisitions budget. Due to the completion of new university buildings and moving of university faculties and institutes to new locations, large amounts of older historical publications, periodicals and students’ research papers were handed over to the library. Processing of these materials has been extremely time and labour-consuming, since all the materials need checking against the catalogues and the library’s capacity in cleaning these materials and making necessary repairs is lacking. As several major library renovations fell into this period, excessive amounts of time and energy were spent in making all kinds of renovation-related preparations, reorganisations and tidying up.

Year: 2023
Subjects: Acute sub-massive pulmonary embolism, Balloon angioplasty, Simultaneous thrombolysis, Maceration

description: Background: Acute sub-massive pulmonary embolism is a common clinical condition, and it is associated with high mortality and morbidity. This condition is commonly associated with various co-morbidities and clinical circumstances. Methods: This is a case report series of four male patients, wherein the thrombolysis and balloon angioplasty was performed simultaneously using a Cordis 6F diagnostic catheter and later exchanged with a 6F guide catheter in the respective pulmonary artery when a larger balloon was required. Results: All these four patients achieved successful revascularization of the respective pulmonary artery. One patient expired 30 hours after the procedure with a significant reduction in the symptoms suddenly, which was likely a second episode of pulmonary embolism. No bleeding manifestations were observed in any of the patients. The other three patients are on follow-up. Conclusion: Simultaneous coronary balloon dilatation and thrombolysis is a useful method in the treatment of sub-massive acute pulmonary embolism. If needed, higher caliber balloons can be used for the same technique using guide catheters.
description: The images presented are from four patients who underwent catheter-related interventions, which included balloon angioplasty and simultaneous thrombolysis during the treatment of acute submissive pulmonary embolism.

description: A new parametrization of the multi-channel S-matrix is used to fit scattering data and then to locate the resonances as its poles. The S-matrix is written in terms of the corresponding "in" and "out" Jost matrices which are expanded in the Taylor series of the collision energy E around an appropriately chosen energy E0. In order to do this, the Jost matrices are written in a semi-analytic form where all the factors (involving the channel momenta and Sommerfeld parameters) responsible for their "bad behaviour" (i.e. responsible for the multi-valuedness of the Jost matrices and for branching of the Riemann surface of the energy) are given explicitly. The remaining unknown factors in the Jost matrices are analytic and single-valued functions of the variable E and are defined on a simple energy plane. The expansion is done for these analytic functions and the expansion coefficients are used as the fitting parameters. The method is tested on a two-channel model, using a set of artificially generated data points with typical error bars and a typical random noise in the positions of the points.

description: Small and Medium size Enterprises (SME) are considered as a backbone of many developing and developed economies of the world; they are the driving force to any major economy across the globe. Through Cloud Computing firms outsource their entire information technology (IT) process while concentrating more on their core business. It allows businesses to cut down heavy cost incurred over IT infrastructure without losing focus on customer needs. However, Cloud industry to an extent has struggled to grow among SMEs due to the reluctance and concerns expressed by them. Throughout the course of this study several interviews were conducted and the literature was reviewed to understand how cloud providers offer services and what challenges SMEs are facing. The study identified issues like cloud knowledge, interoperability, security and contractual concerns to be hindering SMEs adoption of cloud services. From the interviews common practices followed by cloud vendors and what concerns SMEs have were identified as a basis for a cloud framework which will bridge gaps between cloud vendors and SMEs. A stepwise framework for cloud adoption is formulated which identifies and provides recommendation to four most predominant challenges which are hurting cloud industry and taking SMEs away from cloud computing, as well as guide SMEs aiding in successful cloud adoption. Moreover, this framework streamlines the cloud adoption process for SMEs by removing ambiguity in regards to fundamentals associated with their organisation and cloud adoption process.

description: A Decade Full of Renovations at the University of Tartu Library The library building, which entered its 40th year of functioning on 22 February 2022, had already for many years been urgently needing renovation. Some partial renovations had been made a few years earlier. In 2012, under the CO2 emissions quotas project, the library ventilation system was renewed, all windows were replaced and the roof and the front of the building were provided with thermal insulation; in 2013, the renovation proceeded to the reading rooms of the humanities and social sciences and a lift was installed in the building. However, because of the poor safety situation of the collections and people and due to the regulations of the Rescue Board, it was necessary to undertake a major renovation of the whole building. Large-scale preparations for the renovation took several years. The process, planned to be done by stages which should have closed the library for users for only a few months, started in summer 2016. In reality, for different reasons it took two years and it was completed in August 2018. Although we were not able to get everything that we had wanted, for example, the 24/7 area, both the users and the staff members are all very happy with the renewed library.

description: Renewed Library – the Place, the Space, Technology and People In the past decade, the most important event and key word for the user services at our library was, without doubt, the renovation of the library building. Our preparations for the renovation were based on the understanding that the modern university library has to meet the academic needs and reflect the values, missions and objectives of its own and those of the university, as well as to host new knowledge and technology and offer ways for using them. Accordingly, we did not renovate only the building, redesigning the rooms and installing new flooring, shelving and furniture, but we changed some approaches to user services and to the user-library communication. This essay is an attempt to give some philosophical interpretations of these changes and to relate them with the needs of new generations of library users and new aspects of the information society.

description: We analyze two two-mode continuous variable separable states with the same marginal states. We adopt the definition of classicality in the form of well-defined positive Wigner function describing the state and find that although the states possess positive local Wigner functions, they exhibit negative Wigner functions for the global states. Using the negativity of Wigner function as an indicator of nonclassicality, we show that despite these states possess different negativities of the Wigner function, they do not reveal this difference as phase space nonclassicalities such as negativity of the Mandel $Q$ parameter or quadrature squeezing. We then concentrate on quantum correlation of these states and show that quantum discord and local quantum uncertainty, as two well-defined measures of quantum correlation, manifest the difference between negativity of the Wigner functions. The non-Gaussianity of these states is also examined and show that the difference in behavior of their non-Gaussianity is the same as the difference between negativity of their Wigner functions. We also investigate the influence of correlation rank criterion and find that when the states can be produced locally from classical states, the Wigner functions can not reveal their quantum correlations.

Stochastic epidemic models featuring contact tracing with delays

description: This paper is concerned with a stochastic model for the spread of an SEIR (susceptible -> exposed (=latent) -> infective -> removed) epidemic with a contact tracing scheme, in which removed individuals may name some of their infectious contacts, who are then removed if they have not been already after some tracing delay. The epidemic is analysed via an approximating, modified birth-death process, for which a type-reproduction number is derived in terms of unnamed individuals, that is shown to be infinite when the contact rate is sufficiently large. We obtain explicit results under the assumption of either constant or exponentially distributed infectious periods, including the epidemic extinction probability in the former case. Numerical illustrations show that, while the distributions of latent periods and delays have an effect on the spread of the epidemic, the assumption of whether the delays experienced by individuals infected by the same individual are of the same or independent length makes little difference.

description: Erasure codes are increasingly being studied in the context of implementing atomic memory objects in large scale asynchronous distributed storage systems. When compared with the traditional replication based schemes, erasure codes have the potential of significantly lowering storage and communication costs while simultaneously guaranteeing the desired resiliency levels. In this work, we propose the Storage-Optimized Data-Atomic (SODA) algorithm for implementing atomic memory objects in the multi-writer multi-reader setting. SODA uses Maximum Distance Separable (MDS) codes, and is specifically designed to optimize the total storage cost for a given fault-tolerance requirement. For tolerating $f$ server crashes in an $n$-server system, SODA uses an $[n, k]$ MDS code with $k=n-f$, and incurs a total storage cost of $\frac{n}{n-f}$. SODA is designed under the assumption of reliable point-to-point communication channels. The communication cost of a write and a read operation are respectively given by $O(f^2)$ and $\frac{n}{n-f}(δ_w+1)$, where $δ_w$ denotes the number of writes that are concurrent with the particular read. In comparison with the recent CASGC algorithm, which also uses MDS codes, SODA offers lower storage cost while pays more on the communication cost. We also present a modification of SODA, called SODA$_{\text{err}}$, to handle the case where some of the servers can return erroneous coded elements during a read operation. Specifically, in order to tolerate $f$ server failures and $e$ error-prone coded elements, the SODA$_{\text{err}}$ algorithm uses an $[n, k]$ MDS code such that $k=n-2e-f$. SODA$_{\text{err}}$ also guarantees liveness and atomicity, while maintaining an optimized total storage cost of $\frac{n}{n-f-2e}$.

description: Measurements of current-voltage (I-V) characteristics of a high quality Al/Al$_2$O$_3$/Al junction at temperatures ranging from 3.5 K to 300 K have been used to extract the barrier properties. Fitting results using Simmons' model led to a constant value of barrier width $s$$\sim$20.8~$\textrmÅ$ and a continuous increase in the barrier height with decreasing temperature. The latter is used to determine the energy band gap temperature dependence and average phonon frequency $ω$ = 2.05 $\times$ 10$^{13}$ sec$^{-1}$ in Al$_2$O$_3$, which adds confidence to the precision of our measurements. The barrier parameters are used to extract the temperature dependent dwell times in tunneling ($τ_D$ = 3.6 $\times$ 10$^{-16}$ sec at mid-barrier energies) and locate resonances above the barrier.

In particular, we design a simple and efficient algorithm for computing slope factorizations, based on Newton iteration. One of its main features is that we avoid working with fractional exponents. We pay particular attention to stability, and analyze the behavior of the algorithm using several precision models.

description: In this paper we present a new robust sound source localization and tracking method using an array of eight microphones (US patent pending) . The method uses a steered beamformer based on the reliability-weighted phase transform (RWPHAT) along with a particle filter-based tracking algorithm. The proposed system is able to estimate both the direction and the distance of the sources. In a videoconferencing context, the direction was estimated with an accuracy better than one degree while the distance was accurate within 10% RMS. Tracking of up to three simultaneous moving speakers is demonstrated in a noisy environment.

Observing the central engine of GRB170817A
Creators: name: Van Putten, Maurice H.P.M.
Publisher: name: Zenodo
Year: 2018

description: GW170817/GRB170817A establishes a double neutron star merger as the progenitor of a short gamma-ray burst, starting 1.7 s post-coalescence. GRB170817A represents prompt or continuous emission from a newly formed hyper-massive neutron star or black hole. We report on a deep search for broadband extended gravitational-wave emission in spectrograms up to 700 Hz of LIGO O2 data covering this event produced by matched filtering. A detailed discussion is given of signal-to-noise ratios in χ-image analysis of spectrograms and a candidate signature of the central engine. This new pipeline is realized by heterogeneous computing with modern graphics processor units (GPUs). (Based on van Putten, M.H.PM., 2017, PTEP, 093F01; work in collaboration with M. Della Valle.)

description: The nuclei that constitute a crystalline lattice, oscillate relative to each other with a very low energy that is not sufficient to penetrate through the Coulomb barriers separating them. An additional energy, which is needed to tunnel through the barrier and fuse, can be supplied by external electromagnetic waves (X-rays or the synchrotron radiation). Exposing to the X-rays the solid compound LiD (lithium-deuteride) for the duration of 111 hours, we have detected 88 events of the nuclear fusion d+Li6 ---> Be8*. Our theoretical estimate agrees with what we observed. One of possible applications of the phenomenon we found, could be the measurements of the rates of various nuclear reactions (not necessarily fusion) at extremely low energies inaccessible in accelerator experiments.

Continuity of the Feynman-Kac formula for a generalized parabolic equation
Creators: name: Pardoux, Etienne

Publisher: name: arXiv
Year: 2016
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: It is well-known since the work of Pardoux and Peng [12] that Backward Stochastic Differential Equations provide probabilistic formulae for the solution of (systems of) second order elliptic and parabolic equations, thus providing an extension of the Feynman-Kac formula to semilinear PDEs, see also Pardoux and Rascanu [14]. This method was applied to the class of PDEs with a nonlinear Neumann boundary condition first by Pardoux and Zhang [15]. However, the proof of continuity of the extended Feynman-Kac formula with respect to x (resp. to (t,x)) is not correct in that paper. Here we consider a more general situation, where both the equation and the boundary condition involve the (possibly multivalued) gradient of a convex function. We prove the required continuity. The result for the class of equations studied in [15] is a Corollary of our main results.

Exploiting spatiotemporal degrees of freedom for far field subwavelength focusing using time reversal in fractals

description: Materials which possess a high local density of states varying at a subwavelength scale theoretically permit to focus waves onto focal spots much smaller than the free space wavelength. To do so metamaterials -manmade composite media exhibiting properties not available in nature- are usually considered. However this approach is limited to narrow bandwidths due to their resonant nature. Here, we prove that it is possible to use a fractal resonator alongside time reversal to focus microwaves onto $λ/15$ subwavelength focal spots from the far field, on extremely wide bandwidths. We first numerically prove that this approach can be realized using a multiple channel time reversal mirror, that utilizes all the degrees of freedom offered by the fractal resonator. Then we experimentally demonstrate that this approach can be drastically simplified by coupling the fractal resonator to a complex medium, here a cavity, that efficiently converts its spatial degrees of freedom into temporal ones. This allows to achieve deep subwavelength focusing of microwaves using a single channel time reversal. Our method can be generalized to other systems coupling complex media and fractal resonators.

title: The adaptive force as a potential biomechanical parameter in the recovery process of patients with long COVID
Creators: name: Schaefer, Laura

Publisher: name: Universität Potsdam

Subjects: subject: 610 Medizin und Gesundheit

description: Long COVID patients show symptoms, such as fatigue, muscle weakness and pain. Adequate diagnostics are still lacking. Investigating muscle function might be a beneficial approach. The holding capacity (maximal isometric Adaptive Force; AFisomax) was previously suggested to be especially sensitive for impairments. This longitudinal, non-clinical study aimed to investigate the AF in long COVID patients and their recovery process. AF parameters of elbow and hip flexors were assessed in 17 patients at three time points (pre: long COVID state, post: immediately after first treatment, end: recovery) by an objectified manual muscle test. The tester applied an increasing force on the limb of the patient, who had to resist isometrically for as long as possible. The intensity of 13 common symptoms were queried. At pre, patients started to lengthen their muscles at ~50% of the maximal AF (AFmax), which was then reached during eccentric motion, indicating unstable adaptation. At post and end, AFisomax increased significantly to ~99% and 100% of AFmax, respectively, reflecting stable adaptation. AFmax was statistically similar for all three time points. Symptom intensity decreased significantly from pre to end. The findings revealed a substantially impaired maximal holding capacity in long COVID patients, which returned to normal function with substantial health improvement. AFisomax might be a suitable sensitive functional parameter to assess long COVID patients and to support therapy process
