KGTN-ens: Few-Shot Image Classification with Knowledge Graph Ensembles

We propose KGTN-ens, a framework extending the recent Knowledge Graph Transfer Network (KGTN) in order to incorporate multiple knowledge graph embeddings at a small cost. We evaluate it with different combinations of embeddings in a few-shot image classification task. We also construct a new knowledge source - Wikidata embeddings - and evaluate it with KGTN and KGTN-ens. Our approach outperforms KGTN in terms of the top-5 accuracy on the ImageNet-FS dataset for the majority of tested settings

Extracting Maritime Traffic Networks from AIS Data Using Evolutionary Algorithm

The presented method reconstructs a network (a graph) from AIS data, which reflects vessel traffic and can be used for route planning. The approach consists of three main steps: maneuvering points detection, waypoints discovery, and edge construction. The maneuvering points detection uses the CUSUM method and reduces the amount of data for further processing. The genetic algorithm with spatial partitioning is used for waypoints discovery. Finally, edges connecting these waypoints form the final maritime traffic network. The approach aims at advancing the practice of maritime voyage planning, which is typically done manually by a ship’s navigation officer. The authors demonstrate the results of the implementation using Apache Spark, a popular distributed and parallel computing framework. The method is evaluated by comparing the results with an on-line voyage planning application. The evaluation shows that the approach has the capacity to generate a graph which resembles the real-world maritime traffic network

Polite Teacher: Semi-Supervised Instance Segmentation with Mutual Learning and Pseudo-Label Thresholding

We present Polite Teacher, a simple yet effective method for the task of semi-supervised instance segmentation. The proposed architecture relies on the Teacher-Student mutual learning framework. To filter out noisy pseudo-labels, we use confidence thresholding for bounding boxes and mask scoring for masks. The approach has been tested with CenterMask, a single-stage anchor-free detector. Tested on the COCO 2017 val dataset, our architecture significantly (approx. +8 pp. in mask AP) outperforms the baseline at different supervision regimes. To the best of our knowledge, this is one of the first works tackling the problem of semi-supervised instance segmentation and the first one devoted to an anchor-free detector

The Disappearance of Coal Seams Recorded in Associated Gangue Rocks in the SW Part of the Upper Silesian Coal Basin, Poland

Coal seams in the Upper Silesian Coal Basin vanish within the Carboniferous Upper Silesian Sandstone Series and below an unconformity marking the Carboniferous top surface. Changes in the geochemical, mineralogical, petrological and palynological characteristics of gangue rocks associated with the vanished seams record what happened. The observed changes could have been caused by (1) coal-seam paleofire, (2) peat combustion, (3) igneous intrusion, (4) metasomatism and/or (5) weathering. Multifaceted research on samples collected at the Jas-Mos mining area, a part of the operating Jastrz˛ebie-Bzie Coal Mine that are representative of different geological settings in the northern and southern parts of the mining area, point to intra-deposit paleofire as the most plausible reason for the disappearance. Biomarkers enabled recognition of differences in heating duration and oxygen access. Coal seams in the south burned quickly with abundant oxygen supply. Seams in the north pyrolyzed for an extended time under conditions of limited oxygen. Though other methods used proved less sensitive, all confirmed low (100–150 C) paleotemperature heating. Overall, the reason for the local disappearance of the coal seams, making their exploitation difficult and unprofitable, can be assigned to a variety of different processes in a complex overlapping history of variable weathering, heating due to local endogenic fires and, probably, earlier peat combustion

Industrie 4.0: Mitbestimmen - mitgestalten: Umsetzungsstand von Industrie 4.0 in nordrhein-westfälischen Industrieunternehmen

Der höchste Industrie-4.0-Umsetzungsstand ist im Hinblick auf die Nutzung mobiler Endgeräte sowie in den Branchen Elektronik/Elektrotechnik und Automotive festzustellen. Qualifizierungsmaßnahmen können ein wichtiger Baustein sein, wenn es darum geht, die Zunahme der psychischen Belastung bei den Beschäftigten zu vermeiden und Betriebsräte zu einer aktiven Rolle bei technologischen Veränderungen zu befähigen. Trotz einer hohen Bereitschaft zur Weiterbildung ist die Weiterbildungspraxis noch nicht umfangreich umgesetzt

Industrie 4.0: Mitbestimmen - mitgestalten: Umsetzungsstand von Industrie 4.0 in nordrhein-westfälischen Industrieunternehmen

In der vorliegenden Studie wird der Umsetzungsstand von Industrie 4.0 anhand einer quantitativen Befragung von drei relevanten Ebenen (Geschäftsführung, Betriebsrat, Beschäftigte) in produzierenden Betrieben in Nordrhein-Westfalen untersucht. In enger Verzahnung mit der technischen Umsetzung werden dabei die Bereiche der Mitbestimmung und der Qualifizierung untersucht. Der Umsetzungsstand von Industrie 4.0 erweist sich empirisch als variabel. Dabei differenziert sich diese empirische Vielfalt sowohl über die unterschiedlichen Industrie 4.0-Szenarien als auch über die Zugehörigkeit zu konkreten Branchen aus. Aufseiten der Beschäftigten des Shopfloors wird zudem eine stärker werdende Digitalisierung mit einer erhöhten Arbeitsbelastung in Verbindung gebracht. Während eine hohe Bereitschaft besteht, den Herausforderungen durch die Digitalisierung positiv zu begegnen, zeigt sich gleichzeitig eine in nicht umfangreichem Maße umgesetzte Fortbildungs- und Schulungspraxis zu diesem Thema.In the present research study, the status of implementation of Industry 4.0 is investigated by a quantitative survey of three relevant company levels (management, works council, shopfloor) in manufacturing enterprises in North Rhine-Westphalia. Closely enmeshed with the technical implementation, the fields of participation and qualification will be empirically considered. The status of implementation of Industry 4.0 turns out to be empirically diverse. This empirical diversity ranges from different Industry 4.0 scenarios to the affiliation to certain industries. On the shopfloor, the increasing digitization is associated with an increased workload for the employees. On the one hand, there is a high willingness to face positively the challenges of digitization, but still, on the other hand, present trainings and the further education within the scope of Industry 4.0 prove not to be implemented to an appropriate extent

Variants of the FADS1 FADS2 Gene Cluster, Blood Levels of Polyunsaturated Fatty Acids and Eczema in Children within the First 2 Years of Life

Association of genetic-variants in the FADS1-FADS2-gene-cluster with fatty-acid-composition in blood of adult-populations is well established. We analyze this genetic-association in two children-cohort-studies. In addition, the association between variants in the FADS-gene-cluster and blood-fatty-acid-composition with eczema was studied. Data of two population-based-birth-cohorts in The Netherlands and Germany (KOALA, LISA) were pooled (n = 879) and analyzed by (logistic) regression regarding the mutual influence of single-nucleotide-polymorphisms (SNPs) in the FADS-gene-cluster (rs174545, rs174546, rs174556, rs174561, rs3834458), on polyunsaturated fatty acids (PUFA) in blood and parent-reported eczema until the age of 2 years. All SNPs were highly significantly associated with all PUFAs except for alpha-linolenic-acid and eicosapentaenoic-acid, also after correction for multiple-testing. All tested SNPs showed associations with eczema in the LISA-study, but not in the KOALA-study. None of the PUFAs was significantly associated with eczema neither in the pooled nor in the analyses stratified by study-cohort. PUFA-composition in young children's blood is under strong control of the FADS-gene-cluster. Inconsistent results were found for a link between these genetic-variants with eczema. PUFA in blood was not associated with eczema. Thus the hypothesis of an inflammatory-link between PUFA and eczema by the metabolic-pathway of LC-PUFAs as precursors for inflammatory prostaglandins and leukotrienes could not be confirmed by these data

Mapping of ImageNet and Wikidata for Knowledge Graphs Enabled Computer Vision

Knowledge graphs are used as a source of prior knowledge in numerous computer vision tasks. However, such an approach requires to have a mapping between ground truth data labels and the target knowledge graph. We linked the ILSVRC 2012 dataset (often simply referred to as ImageNet) labels to Wikidata entities. This enables using rich knowledge graph structure and contextual information for several computer vision tasks, traditionally benchmarked with ImageNet and its variations. For instance, in few-shot learning classification scenarios with neural networks, this mapping can be leveraged for weight initialisation, which can improve the final performance metrics value. We mapped all 1000 ImageNet labels – 461 were already directly linked with the exact match property (P2888), 467 have exact match candidates, and 72 cannot be matched directly. For these 72 labels, we discuss different problem categories stemming from the inability of finding an exact match. Semantically close non-exact match candidates are presented as well. The mapping is publicly available athttps://github.com/DominikFilipiak/imagenet-to-wikidata-mapping

KLINICZNE PODEJRZENIE ZAPALENIA MIĘŚNIA SERCOWEGO i OSIERDZIA. ROLA OZNACZEŃ BNP W SUROWICY KRWI Doniesienie wstępne

Background: Diagnosis of perimyocarditis is often very challenging. Clinical presentation includes chest pain and ECG changes which are difficult to interpret. Clinical course is usually mild, however, some patients develop heart failure symptoms and require aggressive treatment. Plasma b-type natriuretic peptide (BNP) is a marker of the heamodynamical impairment of the heart. Its diagnostic role in patients with acute perimyocarditis has not yet been examined.Aim: To assess the usefulness of BNP measurement in the diagnosis of perimyocarditis.Methods: The study group consisted of 14 consecutive patients (13 males, mean age 32.1±12.4 years) with suspected perimyocarditis (history of influenza, typical symptoms, ECG and echocardiographic results as well as myocardial necrotic markers). Plasma BNP was assessed at bedside at the time of admission.Results: Plasma BNP, measured in 12 patients, was 163±154 pg/mL (max. 519 pg/mL) and exceeded upper normal level in 6 (50%) patients. When normal levels were adjusted for age and gender, 9 (80%) patients had elevated BNP. One patient had heart failure symptoms and a BNP level of 205 pg/mL. In all 4 patients who had transient myocardial contractility disturbances, detected by echocardiography, BNP level exceeded 100 pg/mL.Conclusions: BNP level is increased in some patients with acute perimyocarditis. BNP elevation is probably associated with haemodynamical stress caused by transient contractility abnormalities. Diagnostic and prognostic role of BNP in acute perimyocarditis requires further studies

Przegląd systematyczny badań z wykorzystaniem kwestionariusza EQ-5D u pacjentów z chorobami sercowo-naczyniowymi w ośmiu państwach Europy Środkowo-Wschodniej

Background: The measurement of health-related quality of life (HRQoL) by validated generic instruments, such as EQ-5D, has become an increasingly important tool for the assessment of health care in a wide range of diagnoses. Aim: We aimed to systematically review EQ-5D literature on cardiovascular diseases in eight Central and Eastern European (CEE) countries. Methods: A structured literature search was conducted in MEDLINE, EMBASE, Web of Science, CINAHL, PsycINFO, Cochrane Library, and the EuroQol website up to November 2016. Original cardiovascular-related studies that reported EQ-5D results were included. Results: Of the 36 papers, 17 reported EQ-5D index scores. Most studies were performed in Poland (n = 24, 67%). The most common diagnosis regarding the number of publications and population size was ischaemic heart disease (n = 13, N = 6394), followed by atrial fibrillation (n = 4, N = 1052). The average EQ-5D index scores ranged from 0.61 to 0.88 and from 0.66 to 0.95 for patients before and after cardiac procedure/surgery, respectively (including angioplasty, coronary artery bypass grafting, ablation, surgical correction of septal defects, transcatheter aortic valve implantation [TAVI]). In all studies baseline scores were lower than the repeated assessments after the procedure, with the most substantial improvement of 0.24 in high-risk elderly patients after TAVI. Studies which did not assess invasive treatment reported mean EQ-5D index scores ranging from 0.18 to 0.80. Conclusions: The number of cardiovascular-related studies reporting HRQoL using EQ-5D has consistently increased in CEE countries over the past decade and is outstanding compared with other clinical fields. The EQ-5D index and EQ VAS scores varied based on the disease severity, patient characteristics, and treatment protocol.Wstęp: Pomiar jakości życia zależnej od zdrowia przy pomocy zwalidowanych instrumentów generycznych, takich jak kwestionariusz EQ-5D, staje się coraz ważniejszym narzędziem oceny opieki zdrowotnej w szerokim spektrum zróżnicowanych chorób. Cel: Przegląd systematyczny badań z wykorzystaniem kwestionariusza EQ-5D przeprowadzonych u pacjentów z chorobami sercowo-naczyniowymi w ośmiu wybranych państwach Europy Środkowo-Wschodniej.Metody: Przeprowadzono systematyczne wyszukiwanie badań w bazach danych MEDLINE, EMBASE, Web of Science, CINAHL, PsycINFO, Cochrane Library oraz na stronie internetowej Grupy EuroQol, opublikowanych do listopada 2016 roku. Włączano badania oryginalne dotyczące pacjentów z chorobami sercowo-naczyniowymi, w których wyniki raportowano z użyciem kwestionariusza EQ-5D.Wyniki: Spośród 36 włączonych badań, w 17 raportowano wyniki indeksu EQ-5D. Większość badań została zrealizowana w Polsce (n=24; 67%). Biorąc pod uwagę liczbę zidentyfikowanych badań oraz wielkość populacji badanych, najczęstszą diagnozę stanowiła choroba wieńcowa serca (n=13 badań, N=6394 pacjentów), zaś drugą najczęstszą – migotanie przedsionków (n=4, N=1052). Średni indeks EQ-5D raportowano w granicach od 0,61 do 0,88 oraz od 0,66 do 0,95, odpowiednio dla pacjentów przed oraz po zastosowaniu leczenia zabiegowego (włączając w to angioplastykę naczyń wieńcowych, pomostowanie tętnic wieńcowych, ablację, chirurgiczną korektę wad zastawkowych serca, przezskórną implantację zastawki aortalnej, TAVI). W obrębie powyższych badań, wyjściowe wyniki pacjentów były zawsze gorsze, niż wyniki po zastosowaniu leczenia zabiegowego, z najbardziej znaczącą zidentyfikowaną poprawą o 0,24 w populacji starszych pacjentów wysokiego ryzyka przechodzących procedurę TAVI. W badaniach dotyczących leczenia zachowawczego średni raportowany indeks EQ-5D mieścił się w granicach od 0,18 do 0,80.Wnioski: Liczba badań z państw Europy Środkowo-Wschodniej dotyczących chorób sercowo-naczyniowych, w których raportowano jakość życia zależną od zdrowia z wykorzystaniem kwestionariusza EQ-5D wzrosła znacząco w trakcie ostatniej dekady i wybija się na tle innych specjalności medycznych. Zgodnie z oczekiwaniami, w zidentyfikowanych badaniach, wartości indeksu EQ-5D oraz wizualnej skali analogowej (EQ VAS) różniły się w zależności od stopnia nasilenia choroby, charakterystyki pacjentów oraz przyjętego sposobu leczenia
