description: Resistor networks have recently been studied as analog computing platforms for machine learning, particularly due to their compatibility with the Equilibrium Propagation training framework. In this work, we explore the computational capabilities of these networks. We prove that electrical networks consisting of voltage sources, linear resistors, diodes, and voltage-controlled voltage sources (VCVSs) can approximate any continuous function to arbitrary precision. Central to our proof is a method for translating a neural network with rectified linear units into an approximately equivalent electrical network comprising these four elements. Our proof relies on two assumptions: (a) that circuit elements are ideal, and (b) that variable resistor conductances and VCVS amplification factors can take any value (arbitrarily small or large). Our findings provide insights that could guide the development of universal self-learning electrical networks.

Healing Village : Reconceptualizing the Rural Hospital
Creators: name: Benner, John
Publisher: name: The University of British Columbia
Year: 2022

description: An escalating factor affecting the fundamental ability for healthcare institutions to provide aid to their respective communities is the growing scarcity of available physicians and nurses. This problem becomes intensified when considering the geographical landscape of urban density, in which more rural communities experience increased difficulty in staff retention. Through the speculation on the digitization of healthcare and our dependency with future automated technologies, we will be able to address healthcare practitioner shortages in rural hospitals by encouraging a hybridization of both in-person and automated practices. By pursuing a hybridized approach, the existing perception of hospitals being cold and lifeless institutions can be challenged through creating better opportunities for higher staff retention and its redirection for more direct care activities.

description: In the economic history of the world, sugar is considered one of the first global products, and the supply-demand in the global market has had a major impact on the development of local markets. The Polish sugar sector has been under the influence of the world market for many years. The reform of the sugar market regulation system in the EU has made the EU and domestic markets increasingly dependent on the world market. The production potential of the domestic sugar industry is greater than the demand on the internal market and the excess supply is directed to exports. The global market is characterized by cyclical fluctuations, which are determined by the cyclical nature of sugar cane cultivation. The length of the business cycle has been reduced to 2-3 years. The world market prices affect domestic sales and export prices and the financial performance of the sugar industry. / Streszczenie. W historii gospodarczej świata cukier jest uznawany za jeden z pierwszych produktów globalnych, a sytuacja podażowo-popytowa na światowym rynku miała duży wpływ na rozwój rynków lokalnych. Polski sektor cukrowniczy od wielu lat pozostaje pod wpływem rynku światowego. Reforma systemu regulacji rynku cukru w UE spowodowała, że rynek unijny i krajowy w coraz większym stopniu są uzależnione od sytuacji na rynku światowym. Potencjał produkcyjny krajowego przemysłu cukrowniczego jest większy od zapotrzebowania na rynku wewnętrznym i nadwyżki podaży są kierowane na eksport. Światowy rynek charakteryzuje się wahaniami koniunkturalnymi, które są determinowane cyklicznością uprawy trzciny cukrowej. Długość cyklu koniunkturalnego skróciła się do 2-3 lat. Ceny rynku światowego wpływają na ceny zbytu i eksportowe w kraju i wyniki finansowe branży cukrowniczej.

description: The subtle interplay between competing degrees of freedom, anisotropy, and spin correlations in frustrated Kitaev quantum materials offers an ideal platform to host non-trivial quantum states with exotic fractional excitations. The signature of spin-freezing behavior of these spin-orbit-driven frustrated magnets is characterized by a bifurcation of zero-field-cooled and field-cooled magnetic susceptibility at low temperatures much below the characteristic interaction energy scale of spins. The temperature dependence of magnetic specific heat exhibits Cm~ T^2 dependence near the freezing temperature. The field-independent behavior of Cm below the freezing temperature implies the presence of exotic low-energy excitations. The aging and memory effect experiments in the Kitaev magnets suggest a non-hierarchical free energy distribution, which differs from the hierarchical organization of conventional spin-freezing. Furthermore, the NMR spin-lattice relaxation rate follows a power law behavior below the spin-freezing temperature, suggesting the persistence of unconventional spin excitation spectra. Herein, we demonstrate that the observed low-temperature spin-freezing phenomena in a few representative Kitaev quantum materials can be effectively explained by the Halperin and Saslow (HS) hydrodynamic modes relevant for non-trivial spin glass materials. The linearly dispersive HS modes are hypothesized to account for instigating non-abelian defect propagation, thereby inducing a spin jam state in the low-temperature regime in frustrated Kitaev magnets. Our investigation reveals that HS modes capture the essence of unconventional spin-freezing ascribed to topological origin in two-dimensional (2D) Kitaev magnets decorated on a honeycomb lattice and its 3D analog hyperhoneycomb that offers a viable ground to extend this framework to a large class of frustrated quantum materials.

description: We consider a single copy of a mixed state of two qubits and derive the optimal trace-preserving local operations assisted by classical communication (LOCC) such as to maximize the fidelity of teleportation that can be achieved with this state. These optimal local operations turn out to be implementable by one-way communication, and always yields a teleportation fidelity larger than 2/3 if the original state is entangled. This maximal achievable fidelity is an entanglement measure and turns out to quantify the minimal amount of mixing required to destroy the entanglement in a quantum state.

description: The aim of the paper is to present the main direction of change in global prices of farm and food products during 2000-2018, determination of the level of change and indication of the reasons for these phenomena. The main source for the data was average annual indices of food prices from the FAO. The analyses showed that in 2011 global food prices reached a level over two and a half times higher than in 2000, but during the period under investigation they increased by 85%. The greatest increase was in the price of vegetable oils due to the development of biofuels. The largest fluctuations in prices were noted in the sugar and dairy markets, and the smallest in the meat market. It was concluded that during longer periods demand had the greatest influence on global food prices, while during shorter periods it was drastic changes in supply. / Streszczenie. Celem artykułu jest przedstawienie głównych kierunków zmian światowych cen artykułów rolno-spożywczych w latach 2000-2018, określenie stopnia ich zmienności i wskazanie przyczyn tych zjawisk. Głównym źródłem danych były średnie roczne indeksy cen żywności FAO. Przeprowadzone analizy pokazały, że w 2011 r. światowe ceny żywności osiągnęły poziom ponad dwuipółkrotnie wyższy niż w 2000 r., a w całym badanym okresie zwiększyły się o 85%. Najbardziej wzrosły ceny olejów roślinnych na skutek rozwoju produkcji biopaliw. Największe fluktuacje cen odnotowano na rynkach cukru i produktów mlecznych, a najmniejsze na rynku mięsa. Stwierdzono, że w długim okresie decydujący wpływ na kształtowanie się światowych cen żywności miały uwarunkowania popytowe, natomiast w okresach krótkich – szoki podażowe.

description: GENIUS is a proposal for a large scale detector of rare events like double beta decay, cold dark matter and low-energy solar neutrinos in real time. The idea of GENIUS is to operate a large amount of ``naked'' Ge detectors in liquid nitrogen, with the aim of reducing the background down to a level of 10^(-3) counts/kg keV y. In this work we investigate the contribution to the background of GENIUS coming from argon (39Ar) and krypton (85Kr) contamination in the liquid nitrogen.

description: Abstract: Human functional magnetic resonance imaging (fMRI) typically employs the blood-oxygen-level-dependent (BOLD) contrast mechanism. In non-human primates (NHP), contrast enhancement is possible using monocrystalline iron-oxide nanoparticles (MION) contrast agent, which has a more temporally extended response function. However, using BOLD fMRI in NHP is desirable for interspecies comparison, and the BOLD signal’s faster response function promises to be beneficial for rapid event-related (rER) designs. Here, we used rER BOLD fMRI in macaque monkeys while viewing real-world images, and found visual responses and category selectivity consistent with previous studies. However, activity estimates were very noisy, suggesting that the lower contrast-to-noise ratio of BOLD, suboptimal behavioural performance, and motion artefacts, in combination, render rER BOLD fMRI challenging in NHP. Previous studies have shown that rER fMRI is possible in macaques with MION, despite MION’s prolonged response function. To understand this, we conducted simulations of the BOLD and MION response during rER, and found that no matter how fast the design, the greater amplitude of the MION response outweighs the contrast loss caused by greater temporal smoothing. We conclude that although any two of the three elements (rER, BOLD, NHP) have been shown to work well, the combination of all three is particularly challenging.
Fast-pairwise collective neutrino oscillations associated with asymmetric neutrino emissions in core-collapse supernova

description: We present a linear stability analysis of the fast-pairwise neutrino flavor conversion based on a result of our latest axisymmetric core-collapse supernova (CCSN) simulation with full Boltzmann neutrino transport. In the CCSN simulation, coherent asymmetric neutrino emissions of electron-type neutrinos ($ν_{\rm e}$) and their anti-particles ($\barν_{\rm e}$), in which the asymmetry of $ν_{\rm e}$ and $\barν_{\rm e}$ is anti-correlated with each other, occur at almost the same time as the onset of aspherical shock expansion. We find that the asymmetric neutrino emissions play a crucial role on occurrences of fast flavor conversions. The linear analysis shows that unstable modes appear in both pre- and post-shock flows; for the latter they appear only in the hemisphere of higher $\barν_{\rm e}$ emissions (the same hemisphere with stronger shock expansion). We analyze in depth the characteristics of electron-lepton-number (ELN) crossing by closely inspecting the angular distributions of neutrinos in momentum space. The ELN crossing happens in various ways, and the property depends on the radius: in the vicinity of neutron star, $\barν_{\rm e}$ ($ν_{\rm e}$) dominates over $ν_{\rm e}$ ($\barν_{\rm e}$) in the forward (backward) direction: at the larger radius the ELN crossing occurs in the opposite way. We also find that the non-radial ELN crossing occurs at the boundary between no ELN crossing and the radial one, which is an effect of genuine multi-D transport. Our findings indicate that the collective neutrino oscillation may occur more commonly in CCSNe and suggest that the CCSN community needs to accommodate these oscillations self-consistently in the modelling of CCSNe.

description: Abstract: While most testicular germ cell tumours (TGCTs) exhibit exquisite sensitivity to platinum chemotherapy, ~10% are platinum resistant. To gain insight into the underlying mechanisms, we undertake whole exome sequencing and copy number analysis in 40 tumours from 26 cases with platinum-resistant TGCT, and combine this with published genomic data on an additional 624 TGCTs. We integrate analyses for driver mutations, mutational burden, global, arm-level and focal copy number (CN) events, and SNV and CN signatures. Albeit preliminary and observational in nature, these analyses provide support for a possible mechanistic link between early driver mutations in RAS and KIT and the widespread copy number events by which TGCT is characterised.

Using localization formulae we compute the prepotential (and its gravitational corrections) for SU(N) supersymmetric ${\cal N}=2, 2^*$ gauge theories on ALE spaces of the $A_n$ type. Furthermore we derive the Poincaré polynomial describing the homologies of the corresponding moduli spaces of self-dual gauge connections. From these results we extract the ${\cal N}=4$ partition function which is a modular form in agreement with the expectations of $SL(2,\Z)$ duality.

Using DDI3 in a Technology Based Assessment environment - opportunities and problems
Creators: name: Barkow, Ingo
Publisher: name: Zenodo
Year: 2011

description: The Technology Based Assessment (TBA) group at the German Institute for International Educational Research (DIPF) uses DDI3 in several settings to record metadata for paper pencil environments. Nevertheless, as the original aim of the group is to transit studies from paper pencil to computer based assessment it is planned to evolve electronic questionnaires (e.g. CAPI and CATI instruments) like they are used in studies like PISA or PIAAC to a common standard. At the moment TBA uses an own propriety XML structure to describe the items within the questionnaire, but is considering moving towards DDI3 also in the rendering engine which means the metadata and item development tool programmed for the pp instruments can be used as item editor for computer based questionnaires. This presentation will show the opportunities and also challenges for this process as well as introducing a workflow from the metadata editor to the rendering engine. Furthermore the newest version of Metadata Editor as well as a first prototype of the rendering engine will be shown. All tools in this presentation are open source software and can be requested for an own usage.

description: Physics informed neural networks (PINNs) are deep learning based techniques for solving partial differential equations (PDEs) encounted in computational science and engineering. Guided by data and physical laws, PINNs find a neural network that approximates the solution to a system of PDEs. Such a neural network is obtained by minimizing a loss function in which any prior knowledge of PDEs and data are encoded. Despite its remarkable empirical success in one, two or three dimensional problems, there is little theoretical justification for PINNs. As the number of data grows, PINNs generate a sequence of minimizers which correspond to a sequence of neural networks. We want to answer the question: Does the sequence of minimizers converge to the solution to the PDE? We consider two classes of PDEs: linear second-order elliptic and parabolic. By adapting the Schauder approach and the maximum principle, we show that the sequence of minimizers strongly converges to the PDE solution in $C^0$. Furthermore, we show that if each minimizer satisfies the initial/boundary conditions, the convergence mode becomes $H^1$. Computational examples are provided to illustrate our theoretical findings. To the best of our knowledge, this is the first theoretical work that shows the consistency of PINNs.

description: The article attempts to compare the importance of agribusiness in the economy in Ukraine and Poland. The analysis covered the years 2001-2015. The data came from official statistical sources. It was found that the importance of agribusiness to the Polish economy decreased over the entire period considered, its share in GVA in whole economy in 2015 was 6%, while in Ukraine it was as much as 15% and in recent years has been increasing. Agrobusiness also had a high share in exports. In Poland, it was 15, and in Ukraine as much as 38% in 2015. The employment structure in agribusiness was dominated by employment in agriculture with a share of about 80% in both countries. The internal structure of agribusiness was more modern in Poland, where as much as 58% of gross value added of agribusiness was generated in the food processing sector. In Ukraine, it was only 24%. The importance of agribusiness in the Ukrainian economy was higher than in Poland, it also has there a more raw character. The bigger potential for further development of agribusiness is in Ukraine, due to the large agricultural land resources and the large potential for increased production and processing of food and its exports. / Streszczenie.

Stwierdzono, że znaczenie agrobiznesu w Polsce w całym okresie zmniejszało się, a jego udział w wartości dodanej brutto w gospodarce wynosił w 2015 roku 6%, podczas, gdy na Ukrainie było to aż 15% i w ostatnich latach wzrastało. Agrobiznes miał też wysoki udział w eksporcie. W Polsce było to 15%, a na Ukrainie aż 38% w 2015 roku. W strukturze zatrudnienia w agrobiznesie dominowało rolnictwo z udziałem około 80% w obu krajach. Wewnętrzna struktura agrobiznesu była nowocześniejsza w Polsce, gdzie aż 58% wartości dodanej brutto było generowane w sektorze przetwórstwa żywności. Na Ukrainie było to tylko 24%. Znaczenie agrobiznesu w gospodarce ukraińskiej było wyższe niż w polskiej, ma on też tam bardziej surowcowy charakter. Na Ukrainie większy jest potencjał dalszego rozwoju wynikający z dużych zasobów ziemi rolniczej i możliwości wzrostu przetwórstwa żywności i jej eksportu.

description: Changepoint models enjoy a wide appeal in a variety of disciplines to model the heterogeneity of ordered data. Graphical influence diagnostics to characterize the influence of single observations on changepoint models are, however, lacking. We address this gap by developing a framework for investigating instabilities in changepoint segmentations and assessing the influence of single observations on various outputs of a changepoint analysis. We construct graphical diagnostic plots that allow practitioners to assess whether instabilities occur; how and where they occur; and to detect influential individual observations triggering instability. We analyze well-log data to illustrate how such influence diagnostic plots can be used in practice to reveal features of the data that may otherwise remain hidden. Supplementary materials for this article are available online.

description: The planned CAP reform will determine the capacity of EU agriculture in facing challenges, especially those related to climate change and growing international competition. The aim of the paper is to assess the EC’s reform proposals in the context of globalisation and integration processes. The paper is based on the analysis of the EC’s proposals for the CAP 2021-2027. The results show that the proposed changes in the CAP are limited and they do not ensure significant support for the agricultural sector. They also are not adequately precise to evaluate them. Moreover, the proposed change in the CAP implementation model poses a serious risk of the CAP disintegration, which will not help the EU in its trade talks with other partners and thus can be detrimental to the future of the EU agri-food sector. It seems that the first step to make the CAP more effective is to strengthen its monitoring system.

Collaboration in Data Documentation: Developing STARDAT - The Data Archiving Suite
Creators: name: Zenk-Möltgen, Wolfgang
Publisher: name: Zenodo
Year: 2011

description: Providing high quality data and documentation is a major demand on archives and researchers in the field of survey research. GESIS has been developing tools to increase standardized documentation processes on study level and on dataset level (e.g. DBKEdit, a web-based editing system for bi-lingual study descriptions, or DSDM for language specific documentation on variable level). However, the challenges of the DDI Version 3 and the collaboration needs at different stages of the data life cycle leaded to the awareness that an integrated management system for metadata is needed. Therefore GESIS started a project to develop "STARDAT - The Data Archiving Suite". It will be based on DDI 3 and will contain modules for structured metadata capture, management, and administration. STARDAT will be integrated into the workflow between data depositors, data managers, and data users. For this reason, a web-based data ingest module will be provided, that allows researchers to deliver metadata already when the project starts. Requirements of data curation, data documentation, data publication, and long-term availability will be incorporated. STARDAT will allow multi-language documentation on study and variable level, as well as the inclusion of further information, e.g. about related publications, classifications, continuity guides, scales or trends.

description: The aim of the analysis is to identify the key changes that occurred on the Russian beef market in the years 1990-2017. The research covered all elements of the market. The basis for the assessment data were taken from the Russian Statistical Yearbooks and from the US Foreign Agricultural Service USDA. Dynamics were indexed on fixed and variable bases. The analysis allows to conclude that all elements of the market were reduced during the period under consideration. The beef population and production as well as its imports and consumption decreased. This happened despite the support from the state. This support (subsidies) is relatively small compared to the support of pig or poultry farming. However, it allowed to create the basis of beef cattle breeding and its development in the long term. / Streszczenie. Celem analizy jest zidentyfikowanie kluczowych zmian, jakie nastąpiły na rosyjskim rynku wołowiny w latach 1990-2017. Badaniem objęto wszystkie elementy rynku. Podstawę oceny stanowiły dane pochodzące z rosyjskich Roczników Statystycznych oraz z publikacji amerykańskich Foreign Agricultural Service USDA. Do pomiaru dynamiki wykorzystano indeksy o stałej i zmiennej podstawie. Analiza pozwoliła na stwierdzenie, że w badanym okresie wszystkie elementy rynku uległy redukcji. Zmniejszyło się pogłowie i produkcja wołowiny, a także jej import oraz spożycie. Nastąpiło to pomimo wsparcia ze strony państwa. Wsparcie (subsydia) są relatywnie małe w porównaniu ze wsparciem chowu trzody czy drobiu. Pozwala ono jednak na tworzenie podstaw chowu bydła mięsnego i jego rozwoju w dłuższej perspektywie.

description: We consider the process $e^+e^-\to\tiχ^+_i\tiχ^-_j$ at a linear collider with transverse $e^{\pm}$ beam polarization. We investigate the influence of the CP phases on azimuthal asymmetries in $e^+e^-\to\tiχ^+_i\tiχ^-_j$ with subsequent two-body decays $\tiχ^-_j\to \tiν_{\ell}\ell^-$ and $\tiχ^-_j\to W^-\tiχ^0_1$. We show that triple product correlations involving the transverse $e^{\pm}$ beam polarization vanish if at least one subsequent chargino decay is not observed. We derive this result within the Minimal Supersymmetric Standard Model (MSSM) with complex parameters, however, it holds also in the general MSSM with SUSY flavour violation.

description: This panel addresses recent developments in the DDI implementation landscape - new tools developments, and related developments in the standards. There has been much activity in the DDI community within the past year. Some of the existing tools have been extended with major new features; there are several new tools which support and use DDI 3, and there have been some developments for the DDI standards by the DDI Alliance itself, which will influence on-going tools support. Discussion covers both open-source and freely available tools, and also commercial tools which support DDI 3. This panel summarizes these recent developments, and highlights the points of interest. The panel is divided in three blocks A1, C1 and D1.

description: All known examples confirming the possibility of an exponential separation between classical simulation algorithms and stoquastic adiabatic quantum computing (AQC) exploit symmetries that constrain adiabatic dynamics to effective, symmetric subspaces. The symmetries produce large effective eigenvalue gaps, which in turn make adiabatic computation efficient. We present a classical algorithm to efficiently sample from the effective subspace of a $k$-local stoquastic Hamiltonian $H$, without a priori knowledge of its symmetries (or near-symmetries). Our algorithm maps any $k$-local Hamiltonian to a graph $G=(V,E)$ with $\lvert V \rvert = O\left(\mathrm{poly}(n)\right)$ where $n$ is the number of qubits. Given the well-known result of Babai, we exploit graph isomorphism to study the automorphisms of $G$ and arrive at an algorithm quasi-polynomial in $\lvert V\rvert$ for producing samples from the effective subspace eigenstates of $H$. Our results rule out exponential separations between stoquastic AQC and classical computation that arise from hidden symmetries in $k$-local Hamiltonians. Furthermore, our graph representation of $H$ is not limited to stoquastic Hamiltonians and may rule out corresponding obstructions in non-stoquastic cases, or be useful in studying additional properties of $k$-local Hamiltonians.

description: Mixed models are frequently used in social and economic analysis. Typically, the analyzed data are gathered through a survey sample from the population of interest. The underlying survey design may be non-ignorable, leading to possible bias in the regression parameters if not accounted for. To circumvent this problem, survey weights should be included in the estimation process. We propose a survey weighted generalized linear mixed model allowing for unit-specific survey weights and a flexible random effects structure. An estimation procedure is proposed and evaluated in two simulation studies under different scenarios. The first simulation study strongly encourages the use of survey weighted generalized linear mixed models if the survey design is non-ignorable. The second one replicates a previous simulation study in order to study the competitivity of the proposed method with established approaches and software. Further, the proposed method is used to re-estimate a regression on reading proficiency using US PISA data from 2000. Supplementary files for this article are available online.

description: We suggest an efficient scheme for quantum computation with linear optical elements utilizing "linked" photon states. The linked states are designed according to the particular quantum circuit one wishes to process. Once a linked-state has been successfully prepared, the computation is pursued deterministically by a sequence of teleportation steps. The present scheme enables a significant reduction of the average number of elementary gates per logical gate to about 20-30 CZ_{9/16} gates.

description: We introduce the `Joule stepping' technique, whereupon a constantly-biased bolometer has its bias voltage modified by a small additional step. We demonstrate this technique using a composite NTD semiconductor bolometer and a pulsing device which sends an extra step in voltage. We demonstrate the results of the technique over a range of bias voltages at 100, 200, and 300 mK. We find that Joule stepping allows us to directly measure long thermal tails with low amplitudes in the bolometer response, and could be a useful tool for quickly and easily understanding response functions of bolometric detectors. We also show that the derivative of the Joule step is equivalent to the bolometer response to a $δ$-pulse (or Joule pulse), which allows for greater understanding of fast transient behaviour.

Dark matter haloes: an additional criterion for the choice of fitting density profiles

Subjects: subject: Astrophysics (astro-ph)

description: Simulated dark matter haloes are fitted by self-similar, universal density profiles, where the scaled parameters depend only on a scaled (truncation) radius which, in turn, is supposed to be independent on the mass and the formation redshift. A criterion for the choice of the best fitting density profile is proposed, with regard to a set of high-resolution simulations, where some averaging procedure on scaled density profiles has been performed, in connection with a number of fitting density profiles. An application is made to a pair of sets each made of a dozen of high-resolution simulations, which are available in literature, in connection with two currently used fitting density profiles, where the dependence of the scaled radius on the mass and the formation redshift, may be neglected to a first extent. Some features of the early evolution of dark matter haloes represented by fitting density profiles, are discussed in the limit of the spherical top-hat model.

description: The continuous down-scaling of transistors has been the key to the successful development of current information technology. However, with Moore's law reaching its limits, the development of alternative transistor architectures is urgently needed. Transistors require a switching voltage of at least 60 mV for each tenfold increase in current, that is, a subthreshold swing (SS) of 60 mV per decade (dec). Alternative tunnel field-effect transistors (TFETs) are widely studied to achieve a sub-thermionic SS and high I60 (the current where SS becomes 60 mV/dec). Heterojunction (HJ) TFETs show promise for delivering a high I60, but experimental results do not meet theoretical expectations due to interface problems in the HJs constructed from different materials. Here, we report a natural HJ-TFET with spatially varying layer thickness in black phosphorus without interface problems. We achieved record-low average SS values over 4-5 dec of current (SSave_4dec = ~22.9 mV/dec and SSave_5dec = ~26.0 mV/dec) with record-high I60 (I60 = 0.65-1 uA/um), paving the way for application in low-power switches.

Year: 2011

description: This paper is about how the xml-database eXist can store and index DDI-instances. Some of the technical advantages of the implementation is very fast full-text search in documents, fast and flexible indexing with the built-in indexing engine Lucene and fast development of xml-webservices directly within eXist. We will look at the implementation of Swedish National Data Service's DDI3 based question bank in eXist and show examples of indexing and accessing DDI using eXist.

description: Background: Geographical variations in the incidence and tumour stage distribution of oesophageal cancer in Sweden are not well characterised. Methods: Using data from the Swedish Cancer Registry over 45 years (1972–2016), we compared the age-standardised incidence rates of oesophageal cancer by histological type across all seven national areas (in five-year periods) and 21 counties (in 15-year periods) in Sweden, and assessed the geographical distribution of tumour stage at diagnosis since 2004. Results: The incidence rate of oesophageal adenocarcinoma increased in all national areas and counties and in both sexes over time, while the rate of oesophageal squamous cell carcinoma decreased from the 1980s onwards. In the latest period (2012– 2016), the incidence rate of adenocarcinoma in men ranged from 3.5/100,000 person-years in West Sweden to 6.2/100,000 person-years in North Middle Sweden. At the county level, the rate of adenocarcinoma in men was lowest in Jämtland (2.7/100,000 person-years) and highest in Gotland (6.2/100 000 person-years) in 2002–2016. The incidence rates of both adenocarcinoma and squamous cell carcinoma in women were below 2/100,000 person-years in all national areas and counties in the latest calendar periods, i.e., 2012–2016 and 2002–2016, respectively. The proportion of patents with tumour stage IV ranged from 22% in Stockholm area to 31% in Middle Norrland, while at the healthcare region level it was lowest in Stockholm healthcare region (23%) and highest in North (30%) and Uppsala-Örebro (29%) healthcare regions. Conclusion: There are considerable geographical variations in the incidence and tumour stage distribution of oesophageal cancer in Sweden.
