description: Let $K$ be a centrally-symmetric convex body in $\mathbb{R}^n$ and let $\|\cdot\|$ be its induced norm on ${\mathbb R}^n$. We show that if $K \supseteq r B_2^n$ then: \[ \sqrt{n} M(K) \leqslant C \sum_{k=1}^{n} \frac{1}{\sqrt{k}} \min\left(\frac{1}{r} , \frac{n}{k} \log\Big(e + \frac{n}{k}\Big) \frac{1}{v_{k}^{-}(K)}\right) . \] where $M(K)=\int_{S^{n-1}} \|x\|\, dσ(x)$ is the mean-norm, $C>0$ is a universal constant, and $v^{-}_k(K)$ denotes the minimal volume-radius of a $k$-dimensional orthogonal projection of $K$. We apply this result to the study of the mean-norm of an isotropic convex body $K$ in ${\mathbb R}^n$ and its $L_q$-centroid bodies. In particular, we show that if $K$ has isotropic constant $L_K$ then: \[ M(K) \leqslant \frac{C\log^{2/5}(e+ n)}{\sqrt[10]{n}L_K} . \]

description: We are interested in a variation of the SIR (Susceptible/Infected/Recovered) dynamics on the complete graph, in which infected individuals may only spread to neighboring susceptible individuals at fixed rate $λ>0$ while recovered individuals may only spread to neighboring infected individuals at fixed rate $1$. This is also a variant of the so-called chase-escape process introduced by Kordzakhia and then Bordenave & Ganesan. Our work is the first study of this dynamics on complete graphs. Starting with one infected and one recovered individuals on the complete graph with $N+2$ vertices, and stopping the process when one type of individuals disappears, we study the asymptotic behavior of the probability that the infection spreads to the whole graph as $N\rightarrow\infty$ and show that for $λ\in (0,1)$ (resp. for $λ>1$), the infection dies out (resp. does not die out) with probability tending to one as $N\rightarrow\infty$, and that the probability that the infection dies out tends to $1/2$ for $λ=1$. We also establish limit theorems concerning the asymptotic state of the system in all regimes and show that two additional phase transitions occur in the subcritical phase $λ\in (0,1)$: at $λ=1/2$ the behavior of the expected number of remaining infected individuals changes, while at $λ=(\sqrt {5}-1)/2$ the behavior of the expected number of remaining recovered individuals changes. We also study the outbreak sizes of the infection, and show that the outbreak sizes are small if $λ\in(0,1/2]$, exhibit a power-law behavior for $1/2

Year: 2023

description: This poster investigates social vulnerability, which measures resilience in the face of disasters such as floods and hurricanes. Vulnerability does not increase the likelihood of disasters, but rather influences a population or individual's ability to respond and recover from them. Factors influencing vulnerability include but are not limited to: income, race/ethnicity, disability, and education.

description: In a series of papers we proposed a model unifying general relativity and quantum mechanics. The idea was to deduce both general relativity and quantum mechanics from a noncommutative algebra ${\cal A}_Γ$ defined on a transformation groupoid $Γ$ determined by the action of the Lorentz group on the frame bundle $(E, π_M, M)$ over space-time $M$. In the present work, we construct a simplified version of the gravitational sector of this model in which the Lorentz group is replaced by a finite group $G$ and the frame bundle is trivial $E=M\times G$. The model is fully computable. We define the Einstein-Hilbert action, with the help of which we derive the generalized vacuum Einstein equations. When the equations are projected to space-time (giving the "general relativistic limit"), the extra terms that appear due to our generalization can be interpreted as "matter terms", as in Kaluza-Klein-type models. To illustrate this effect we further simplify the metric matrix to a block diagonal form, compute for it the generalized Einstein equations and find two of their "Friedmann-like" solutions for the special case when $G =\mathbb{Z}_2$. One of them gives the flat Minkowski space-time (which, however, is not static), another, a hyperbolic, linearly expanding universe.

description: What is the probability that the number of triangles in $\mathcal{G}_{n,p}$, the Erdős-Rényi random graph with edge density $p$, is at least twice its mean? Writing it as $\exp[- r(n,p)]$, already the order of the rate function $r(n,p)$ was a longstanding open problem when $p=o(1)$, finally settled in 2012 by Chatterjee and by DeMarco and Kahn, who independently showed that $r(n,p)\asymp n^2p^2 \log (1/p)$ for $p \gtrsim \frac{\log n}n$; the exact asymptotics of $r(n,p)$ remained unknown. The following variational problem can be related to this large deviation question at $p\gtrsim \frac{\log n}n$: for $δ>0$ fixed, what is the minimum asymptotic $p$-relative entropy of a weighted graph on $n$ vertices with triangle density at least $(1+δ)p^3$? A beautiful large deviation framework of Chatterjee and Varadhan (2011) reduces upper tails for triangles to a limiting version of this problem for fixed $p$. A very recent breakthrough of Chatterjee and Dembo extended its validity to $n^{-α}\ll p \ll 1$ for an explicit $α>0$, and plausibly it holds in all of the above sparse regime. In this note we show that the solution to the variational problem is $\min\{\frac12 δ^{2/3}\,,\, \frac13 δ\}$ when $n^{-1/2}\ll p \ll 1$ vs. $\frac12 δ^{2/3}$ when $n^{-1} \ll p\ll n^{-1/2}$ (the transition between these regimes is expressed in the count of triangles minus an edge in the minimizer). From the results of Chatterjee and Dembo, this shows for instance that the probability that $\mathcal{G}_{n,p}$ for $ n^{-α} \leq p \ll 1$ has twice as many triangles as its expectation is $\exp[-r(n,p)]$ where $r(n,p)\sim \frac13 n^2 p^2\log(1/p)$. Our results further extend to $k$-cliques for any fixed $k$, as well as give the order of the upper tail rate function for an arbitrary fixed subgraph when $p\geq n^{-α}$.

description: A multianvil cell assembly with octahedral edge length 25 mm has been adapted for high pressure investigations involving water-rich environments up to 6.5 GPa and 400°C. Water-rich samples are confined in Teflon containers with a volume up to 300 mm3. Applicability tests were performed between 250 and 400°C by investigating the transformation of amorphous titania particles close to the rutile–TiO2-II (∼5 GPa) phase boundary, and the transformation of amorphous silica particles close to the quartz–coesite (∼2.5 GPa) and coesite–stishovite (∼7 GPa) phase boundaries. The performed experiments employed 25.4 mm tungsten carbide anvils with a truncation edge length of 15 mm. The sample pressure at loads approaching 820 t was estimated to be around 6.5 GPa. The large volume multianvil cell is expected to have broad and varied application areas, ranging from the simulation of geofluids to hydrothermal synthesis and conversion/crystal growth in aqueous environments at gigapascal pressures.

Our results show that the usual Eyring-Kramers law for asymmetric processes has to be corrected by a factor computable in terms of stabilisers of group orbits. Furthermore, the symmetry can produce additional Arrhenius exponents and modify the spectral gap. The results are based on representation theory of finite groups.

description: The present work provides an economic explanation of a well-known (seeming) violation of the expectations hypothesis of the term structure (EHT) - the frequent finding of unit roots in interest rate spreads. We derive from EHT that the nonstationarity stems from the holding premium, which is hence cointegrated with the spread. We model the premium as being proportional to the integrated variance of excess returns and further propose a cointegration test. Simulating the distribution of the test statistic we actually find cointegration relations between premia and spreads in US data. The EHT appears to perform better than previously thought.

description: We report short-time variations in the plasma tail of C/2013 R1(Lovejoy). A series of short (two to three minutes) exposure images with the 8.2-m Subaru telescope shows faint details of filaments and their motions over 24 minutes observing duration. We identified rapid movements of two knots in the plasma tail near the nucleus (~ 3 x 10^5 km). Their speeds are 20 and 25 km/s along the tail and 3.8 and 2.2 km/s across it, respectively. These measurements set a constraint on an acceleration model of plasma tail and knots as they set the initial speed just after their formation. We also found a rapid narrowing of the tail. After correcting the motion along the tail, the narrowing speed is estimated to be ~ 8 km/s. These rapid motions suggest the need for high time-resolution studies of comet plasma tails with a large telescope.

Year: 2014

description: This paper presents the analysis of rolling contact fatigue damage due to cyclic axle load between wheel/rail and fatigue life comparison between experimental and ANSYS results. The purpose is to see the fatigue life of the rail and to protect it from failure. .For this analysis a three-dimensional finite element model of the wheel/rail interaction is used to investigate the effect of the applied contact loading force at the straight area of the wheel tread and railhead surface. For the experimental part, fatigue test is conducted by taking specimens from the rail material and the specimens are modeled by CATIA V5 and analysis the effect with ANSYS 12.0 by applying different loads for the comparison of the fatigue life.

description: We investigate the production and freeze-out of dark matter with a constant thermally averaged cross-section in a generic bouncing universe framework. Our result shows that, there is a novel avenue that dark matter is produced thermally and take a weakly freezing-out process, besides two previously known cases, the thermally production & strongly freezing-out case and the non-thermally production & weakly freezing-out case, in which the relic abundance of dark matter are inverse and proportional to its cross-section respectively. We calculated the relic abundance of dark matter for this new case, and find its relic abundance is independent of its cross-section. We also present the cosmological constraints on the cross-section and mass relation of dark matter for this new case.

description: The $1/Z$-expansion for the ground state energy of the Coulomb system of an infinitely massive center of charge Z and two electrons (two electron ionic sequence) is studied. A critical analysis of the $1/Z$ coefficients presented in Baker et al, {\em Phys. Rev. \bf A41}, 1247 (1990) is performed and its numerical deficiency is indicated, leading, in particular, to unreliable decimal digits beyond digits 11-12 of the first coefficients. We made a consistency check of the $1/Z$-expansion with accurate energies for $Z = 1 - 10$: the weighted partial sums of the $1/Z$-expansion with Baker et al. coefficients, reproduce systematically the ground state energies of two-electron ions with $Z \geq 2$ up to 12 decimal digits and for $Z=1$ up to 10 decimal digits. This rules out the presence of non-analytic terms at $Z=\infty$ contributing into the first 10-12 decimal digits in the ground state energy; it agrees with the Kato theorem about convergence of the $1/Z$-expansion within that accuracy. The ground state energy of two-electron ions $Z=11\ (Na^{9+})$ and $Z=12\ (Mg^{10+})$ is calculated with 12 decimal digits.

description: We consider a simple cubic array of metallic nanoparticles supporting extended collective plasmons that arise from the near-field dipolar interaction between localized surface plasmons in each nanoparticle. We develop a fully analytical quantum theory of the strong-coupling regime between these collective plasmons and photons resulting in plasmon polaritons in the nanoparticle array. Remarkably, we show that the polaritonic band gap and the dielectric function of the metamaterial can be significantly modulated by the polarization of light. We unveil how such an anisotropic behavior in the plasmonic metamaterial is crucially mediated by the dipolar interactions between the nanoparticles despite the symmetry of the underlying lattice. Our results thus pave the way towards the realization of tunable quantum plasmonic metamaterials presenting interaction-driven birefringence.

Publisher: name: Universität Regensburg
Year: 2010
Subjects: subject: 004 Informatik

description: To avoid insider computer misuse, identity and authorization data referring to the legitimate users of the systems must be properly organized and constantly and systematically analyzed and evaluated. In order to support this, a methodology for structured Identity Management has been developed. This methodology includes gathering of identity data spread among different applications, systematic cleansing of user account data in order to detect semantic as well as syntactic errors, grouping of privileges and access rights, and semiautomatic engineering of user roles. Each of the steps involved includes quality criteria and comprehensive tool support. The focus of this paper is on the data cleansing phase leading to feedback where insider misuse may occur due to existing privileges which go beyond the scope of the users’ current need-to-know.

description: Ce travail de mémoire expose le cheminement parcouru par les auteurs et leurs justifications pour proposer une nouvelle séquence de droit aux élèves autour de la thématique de la responsabilité environnementale. En se basant notamment sur les recommandations du guide de l’éducation à la durabilité et PER, cette séquence a pour ambition d’amener les élèves à se questionner, à réaliser des démarches d’enquête et à favoriser leur créativité pour pouvoir développer des savoirs disciplinaires et transversaux sur le thème de la durabilité, avec en toile de fond l’utilisation d’approches multidimensionnelles à commencer par le modèle du « donut ». Dans la mise en place de cette séquence traitant de questions socialement vives, les auteurs sont partis de la problématique suivante : quelle influence une modalité d’enseignement en indoor et en « outdoor » a-t-elle sur la motivation et les apprentissages des élèves ? La méthodologie mise en place dans le cadre du déroulement de cette séquence en classe durant l’année scolaire 2021-2022 a permis aux auteurs de proposer une analyse tant sur la motivation que sur les apprentissages des élèves ainsi qu’une analyse métacognitive sur le travail réalisé. Les auteurs ont ainsi pu notamment constater que de nombreux liens avec les cadres théoriques proposés peuvent être faits dans le cadre de cette séquence, mais aussi que la complexité d’une approche multidimensionnelle peut avoir un impact non négligeable sur la motivation et les apprentissages des élèves. En effet, cette approche contribue à permettre aux élèves de développer des différents regards et de tendre vers un esprit critique. Forts de ces constats, les auteurs proposent des pistes d’actions afin d’améliorer encore à l’avenir le déroulement de cette séquence, spécialement en mélangeant davantage les modalités d’enseignement en « indoor » et en « outdoor » et en ouvrant une possibilité en vue de favoriser davantage d’interdisciplinarité.

Diffraction tomography on curved boundaries: A projection-based approach

description: An approach to diffraction tomography is investigated for two-dimensional image reconstruction of objects surrounded by an arbitrarily-shaped curve of sources and receivers. Based on the integral theorem of Helmholtz and Kirchhoff, the approach relies upon a valid choice of the Green's functions for selected conditions along the (possibly-irregular) boundary. This allows field projections from the receivers to an arbitrary external location. When performed over all source locations, it will be shown that the field caused by a hypothetical source at this external location is also known along the boundary. This field can then be projected to new external points that may serve as a virtual receiver. Under such a reformation, data may be put in a form suitable for image construction by synthetic aperture methods. Foundations of the approach are shown, followed by a mapping technique optimized for the approach. Examples formed from synthetic data are provided.

description: Le phénomène de l’indiscipline à l’école constitue aujourd’hui une problématique majeure impliquant aussi bien l’élève que l’enseignant, les parents et les autres acteurs de l’institution scolaire. Face à une montée de la critique au sein de notre société moderne qui exige à l’enseignant de justifier ses moindres actions, le rapport de ce dernier à l’élève et à sa pratique se modifie non sans impact sur la santé mentale. Ainsi, trouver des pistes d’action pour améliorer sa pratique et neutraliser les comportements problématiques de certains élèves considérés comme « difficiles » se présente comme une urgente nécessité. Ainsi, l’objectif principal de ce travail est de permettre une meilleure compréhension du phénomène de l’indiscipline à l’école, de ses causes et de ses conséquences sur les acteurs scolaires. Deux dimensions ont été prépondérantes pour comprendre les enjeux de cette problématique. Il s’agit de la complexité identitaire et le rapport des élèves au savoir. La démarche réflexive de mon travail est portée par l’écriture et l’analyse de récits d’expériences. Ma motivation pour cette approche réside dans le fait que, faisant revivre la mémoire, elle réveille ce qui peut être enfoui ou laissé pour compte et constitue une véritable source d’enseignement. Ainsi, le retour sur mes expériences vécues et plus particulièrement dans leur rapport aux langues étrangères m’a permis de constater concrètement l’impact de l’héritage socio-familial sur les apprentissages.
Lightweight Salient Object Detection in Optical Remote-Sensing Images via Semantic Matching and Edge Alignment

description: Recently, relying on convolutional neural networks (CNNs), many methods for salient object detection in optical remote sensing images (ORSI-SOD) are proposed. However, most methods ignore the huge parameters and computational cost brought by CNNs, and only a few pay attention to the portability and mobility. To facilitate practical applications, in this paper, we propose a novel lightweight network for ORSI-SOD based on semantic matching and edge alignment, termed SeaNet. Specifically, SeaNet includes a lightweight MobileNet-V2 for feature extraction, a dynamic semantic matching module (DSMM) for high-level features, an edge self-alignment module (ESAM) for low-level features, and a portable decoder for inference. First, the high-level features are compressed into semantic kernels. Then, semantic kernels are used to activate salient object locations in two groups of high-level features through dynamic convolution operations in DSMM. Meanwhile, in ESAM, cross-scale edge information extracted from two groups of low-level features is self-aligned through L2 loss and used for detail enhancement. Finally, starting from the highest-level features, the decoder infers salient objects based on the accurate locations and fine details contained in the outputs of the two modules. Extensive experiments on two public datasets demonstrate that our lightweight SeaNet not only outperforms most state-of-the-art lightweight methods but also yields comparable accuracy with state-of-the-art conventional methods, while having only 2.76M parameters and running with 1.7G FLOPs for 288x288 inputs. Our code and results are available at https://github.com/MathLee/SeaNet.

description: Nekrotiseeriv pehmekoe infektsioon, mida rahvakeeles sageli ka lihasööjabakteri haiguseks nimetatakse, pakub ravimisel arstidele väljakutseid. Selle tekitajateks olevad toksiine produtseerivad bakterid, sagedamini Streptococcus pyogenes ja Staphylococcus aureus, põhjustavad nahaaluskoe põletikku, isheemiat ja nekroosi. Haigust iseloomustab väga kiire kulg ja raskematel juhtudel lõpeb see sepsise, elundipuudulikkuse või isegi surmaga. Periorbitaalses piirkonnas esineva haiguse puhune suremus varieerub 8,5–14,4% ning see suureneb kuni 30%-ni kaela ja näo alumise piirkonna haaratuse korral (1) ning ligikaudu 76%-ni süsteemsete tüsistuste esinemise korral (2, 3). Periorbitaalse nekrotiseeriva fastsiidi esinemissagedus Ühendkuningriigis on 0,24 juhtu 1 000 000 inimese kohta aastas (4). Kuna haiguse ravi tulemuslikkus sõltub otseselt sümptomite varajasest äratundmisest ja ravi kiirest alustamisest, on oluline jagada selle kohta kogemusi.

description: Ce travail de mémoire a été réalisé par deux enseignantes d’arts visuels en Secondaire I. Nous avons voulu explorer les liens entre didactique des arts visuels et éducation numérique. Dans ce travail, nous mettons en évidence les ponts entre les plans d’étude d’arts visuels et d’éducation numérique, notamment dans le domaine de l’éducation aux médias. Nous avons donc décidé de travailler sur l’éducation aux médias, par le biais de l’enseignement du cinéma. Ainsi, pour répondre à notre question de recherche (comment l’enseignement du cinéma en cours d’arts visuels peut-il permettre d’enrichir la littératie médiatique des élèves ?), un atelier a été créé : l’atelier MashUp. Dans cet atelier, les élèves sont amenés à créer la bande-son d’un film. A travers ce travail, ils expérimentent un outil cinématographique afin d’affiner leurs compétences numériques et médiatiques. Par cette activité, nous allions donc monde numérique et artistique. Dans ce mémoire, nous proposons un compte-rendu de l’expérience, et son analyse.

description: The epidemic threshold of the susceptible-infected-susceptible (SIS) dynamics on random networks having a power law degree distribution with exponent $γ>3$ has been investigated using different mean-field approaches, which predict different outcomes. We performed extensive simulations in the quasistationary state for a comparison with these mean-field theories. We observed concomitant multiple transitions in individual networks presenting large gaps in the degree distribution and the obtained multiple epidemic thresholds are well described by different mean-field theories. We observed that the transitions involving thresholds which vanishes at the thermodynamic limit involve localized states, in which a vanishing fraction of the network effectively contribute to epidemic activity, whereas an endemic state, with a finite density of infected vertices, occurs at a finite threshold. The multiple transitions are related to the activations of distinct sub-domains of the network, which are not directly connected.

description: To identify the impact of kinematic limitations on hand osteoarthritis patients’ ability to perform daily living activities. An experiment was performed on 33 patients and 32 healthy subjects. Active ranges of motion (AROM) of 16 hand joint angles were measured, together with scores of different hand tests of dexterity (Box and Block, Nine Hole Peg, Kapandji) and function (Sollerman Hand Function Test, SHFT). Functional ranges of motion (FROM) were recorded during SHFT tasks. Results by task are also reported. Patients’ AROM is limited in flexion of thumb carpometacarpal and interphalangeal, and finger metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints, and in palmar arch. Patients scored worse in gross dexterity and opposition, but only Kapandji score was correlated with AROM limitations. Pain is mostly reported in patients with limited extension of finger MCP and PIP joints. Patients used significantly different FROM in almost all the joints, and needed more time to accomplish the SHFT tasks. AROM measurements can be used as indicators for early diagnosis. Patients use specific strategies to accomplish each task, arising from AROM limitations; some tasks with very extreme postures. The tasks where precision or force are required for thumb are the most affected ones.Implications for rehabilitationActive range of motion is an indicator for early hand osteoarthritis diagnosis.Patients' functional ranges are reduced, and thumb opposition and gross dexterity are hindered.Rehabilitation should focus especially on tasks requiring precision and thumb strength.Rehabilitation should favor the improvement of task completion times.

description: We show that, in the presence of massive neutrinos, the Galileon gravity model provides a very good fit to the current CMB temperature, CMB lensing and BAO data. This model, which we dub $ν \rm{Galileon}$, when assuming its stable attractor background solution, contains the same set of free parameters as $Λ\rm{CDM}$, although it leads to different expansion dynamics and nontrivial gravitational interactions. The data provide compelling evidence ($\gtrsim 6σ$) for nonzero neutrino masses, with $Σm_ν\gtrsim 0.4\ {\rm eV}$ at the $2σ$ level. Upcoming precision terrestrial measurements of the absolute neutrino mass scale therefore have the potential to test this model. We show that CMB lensing measurements at multipoles $l \lesssim 40$ will be able to discriminate between the $ν \rm{Galileon}$ and $Λ\rm{CDM}$ models. Unlike $Λ\rm{CDM}$, the $ν \rm{Galileon}$ model is consistent with local determinations of the Hubble parameter. The presence of massive neutrinos lowers the value of $σ_8$ substantially, despite of the enhanced gravitational strength on large scales. Unlike $Λ\rm{CDM}$, the $ν \rm{Galileon}$ model predicts a negative ISW effect, which is difficult to reconcile with current observational limits.

description: By cothermolysis of [CpRFe(CO)2]2 [CpR = η5-C5(CH2Ph)5 (Cpbn) (1) and η5-C5Me4C2H4SMe (CpS) (2)] with P4 phosphorus two novel pentaphosphaferrocenes of the formula [CpRFe(η5-P5)] [CpR = CpS (3), Cpbn (4)] have been synthesised and comprehensively characterised. These two products represent the first derivatives of this class of compounds with a functionalised as well as a sterically bulky adjacent cyclopentadienyl ligand. The pentabenzylcyclopentadienyl derivative 4 as well as both of the starting materials [CpRFe(CO)2]2 1 and 2 have been additionally characterised by X-ray diffraction structure determinations. The pentaphosphaferrocene 4 represents in the crystal lattice highly aggregated units via intra- and intermolecular π-stacking interactions of the phenyl rings of the Cpbn ligand.

description: Spinaalne lihasatroofia on geneetiline haigus, mida iseloomustab α-motoneuronite degeneratsioon ja düsfunktsioon seljaajus ja ajutüve tuumades. Haigus on põhjustatud SMN1 (survival of motor neuron 1) geeni muutustest, mille tõttu ei ekspresseerita
motoneuronites närvirakkude tööks vajalikku SMN-valku. Kliiniliselt väljendub see progresseeruva lihasnõrkuse ja -atroofiana, millega võib kaasneda ka hingamispuudulikkus ning neelamis- ja kõnehäired.
Sclerosis multiplex (SM) on noorte täiskasvanute eas avalduv autoimmuunne kesknärvisüsteemi põletikuline haigus, mille tunnuseks on mitmed demüeliniseerivad kolded peaajus ja seljaajus. Kliiniliselt avalduvad ägenemistena tekkivad SMi sümptomid lihasnõrkusena ning häiritud tundlikkuse, tasakaalu- ja nägemishäiretena.

description: Meditsiin, tervishoid ja neid valdkondi reguleerivad poliitikad lähtuvad tõenduspõhisusest. Tõenduse loomiseks kasutatakse prospektiivsete juhuslikustatud kliiniliste uuringute kõrval järjest enam kliinilise ravitegevuse käigus tekkivaid päriselu terviseandmeid. See eeldab standardseid sõnastikke ja hästi struktureeritud andmeid. Üheks niisuguseks standardiks on tõusmas OMOP (Observational Medical Outcomes Partnership) andmemudel. OMOP-andmebaaside struktuurne ja semantiline ühetaolisus lihtsustab standardsete analüüside tegemist, mille abil saab uurimisküsimuste vastused kiiresti ja odavamalt. Rahvusvahelises koostöös OMOP-andmebaaside kasutamine tagab andmete kaitse, kuna teisele osapoolele väljastatakse üksnes isikustamata agregeeritud analüüsi tulemusi. Nüüdseks on 12% maailma rahvastiku terviseandmed viidud OMOP-kujule. Ka Eestil on võimalus seda kasutades olla päriselu andmete kasutamise arengu esirinnas ning suurendada riigisisese ja rahvusvahelise teaduskoostöö võimalusi.

description: Quantum spin Hall (QSH) insulators have gapless topological edge states inside the bulk band gap, which can serve as dissipationless spin current channels protected by the time-reversal symmetry. The major challenge currently is to find suitable materials for this topological state. Here, we predict a new large-gap QSH insulator with bulk direct band gap of $\sim$0.18 eV, in single-layer Bi$_{4}$Br$_{4}$, which could be exfoliated from its three-dimensional bulk material due to the weakly-bonded layered structure. The band gap of single-layer Bi$_{4}$Br$_{4}$ is tunable via strain engineering, and the QSH phase is robust against external strain. In particular, because this material consists of special one-dimensional molecular chain as its basic building block, the single layer Bi$_{4}$Br$_{4}$ could be easily torn to ribbons with clean and atomically sharp edges, which are much desired for the observation and application of topological edge states. Our work thus provides a new promising material for experimental studies and practical applications of QSH effect.
