When the COVID-19 pandemic hit in early 2020, a lot of research efforts were quickly redirected towards studies on SARS-CoV2 and COVID-19 disease, from the sequencing and assembly of viral genomes to the elaboration of robust testing methodologies and the development of treatment and vaccination strategies. At the same time, a flurry of scientific publications around SARS-CoV-2 and COVID-19 began to appear, making it increasingly difficult for researchers to stay up-to-date with latest trends and developments in this rapidly evolving field. The BioKB platform is a pipeline which, by exploiting text mining and semantic technologies, helps researchers easily access semantic content of thousands of abstracts and full text articles. The content of the articles is analysed and concepts from a range of contexts, including proteins, species, chemicals, diseases and biological processes are tagged based on existing dictionaries of controlled terms. Co-occurring concepts are classified based on their asserted relationship and the resulting subject-relation-object triples are stored in a publicly accessible human- and machine-readable knowledge base. All concepts in the BioKB dictionaries are linked to stable, persistent identifiers, either a resource accession such as an Ensembl, Uniprot or PubChem ID for genes, proteins and chemicals, or an ontology term ID for diseases, phenotypes and other ontology terms. In order to improve COVID-19 related text mining, we extended the underlying dictionaries to include many additional viral species (via NCBI Taxonomy identifiers), phenotypes from the Human Phenotype Ontology (HPO), COVID-related concepts including clinical and laboratory tests from the COVID-19 ontology, as well as additional diseases (DO) and biological processes (GO). We also added all viral proteins found in UniProt and gene entries from EntrezGene to increase the sensitivity of the text mining pipeline to viral data. To date, BioKB has indexed over 270’000 sentences from 21’935 publications relating to coronavirus infections, with publications dating from 1963 to 2021, 3’863 of which were published this year. We are currently working to further refine the text mining pipeline by training it on the extraction of increasingly complex relations such as protein-phenotype relationships. We are also regularly adding new terms to our dictionaries for areas where coverage is currently low, such as clinical and laboratory tests and procedures and novel drug treatments. [less ▲]

Cost-optimization through the minimization of hardware and processing costs with minimal loss in performance is an interesting design paradigm in evolving and emerging Multiple-Input-Multiple-Output (MIMO) radar systems. This optimization is a challenging task due to the increasing Radio Frequency (RF) hardware complexity as well as the signal design algorithm complexity in applications requiring high angular resolution. Towards addressing these, the paper proposes a low-complexity signal design framework, which incorporates a generalized time multiplex scheme for reducing the RF hardware complexity with a subsequent discrete phase modulation. The scheme further aims at achieving simultaneous transmit beamforming and maximum virtual MIMO aperture to enable better target detection and discrimination performance. Furthermore, the paper proposes a low-complexity signal design scheme for beampattern matching in the aforementioned setting. The conducted performance evaluation indicates that the listed design objectives are met. [less ▲]

Evidence on the time-varying effects of migration, remittances, and child education in African contexts remains scarce. This study employs panel data to examine educational outcomes – school enjoyment, and class ranking – of children whose parents migrated internally or internationally and who received in-kind remittances, monetary remittances, or both. The data were collected in 2013, 2014, and 2015 on a panel of school-going children and youths aged from 12 to 21 in two urban areas with high out-migration rates in Ghana: Kumasi and Sunyani (N = 741). The panel includes children of both migrant and non-migrant parents. Results indicate dynamic patterns of sending remittances over years, with preferences converging toward sending both in-kind and monetary remittances by internal and international migrant parents. Overall, the education of children benefits when they receive both in-kind and monetary remittances. The positive effects are further enhanced when remittances are directly invested in child education. The absence of remittances has more negative effects on child education, especially for girls. This study gives a more nuanced understanding of the dynamic and intertwined associations between parental migration, remittances, and the education of children in transnational families. [less ▲]

We definitely live in an increasingly urban World for half of humanity now lives in cities. Cities provide wealth but also negatively impact the environment and the health of citizens. Arguably the benefits and costs of cities relate to both their size, in population terms, and their internal structure, in terms of the relative spatial arrangement of built-up and natural land. Much of urban research focusses on very large cities and urban cores. Yet 3 urban human out of 4 live in cities of less than 4 million inhabitants (according to the global GHSL dataset). Similarly, 3 out of 4 in a typical (European) city do not live in its core but beyond (using a 7-8km radius to define core for a city like London or Paris). To address urban sustainability issues and design adaptation policies, these 75% certainly count and, we can argue, also deserve specific attention because of the relative proximity between urban and non-urban (natural) use that smaller cities and suburban (non-core) areas may permit. In this respect, it is key to understand how the internal structure of cities, in particular the form and density of built-up areas and the interwoven green space emerge out of the core up until the fringe. It is also key to understand whether the form of cities, especially density gradients and the share of urbanised/non-urbanised land change with city size. In this talk we draw lessons from 2 research approaches to urban forms: one theoretical that uses spatial micro-economic simulations, and one empirical that uses spatially detailed land use datasets. Our theoretical simulations relate individual behaviour to urban forms while our empirics relate urban forms to city size. Both have in common a radial perspective to cities, i.e. explicitly or implicitly assuming that the accessibility trade-off to a given centre is a key determinant of locations and land uses. In both cases, we look at urbanisation and green space structures and at pollution exposure as an example of impact. [less ▲]

Objectives: Since video-assisted thoracic surgery (VATS) was first performed in the early 1990s, there have been many developments, and the conversion rate has decreased over the years. This article highlights the specific outcomes of patients undergoing conversion to thoracotomy despite initially scheduled VATS lung resection. Methods: We retrospectively reviewed 501 patients who underwent thoracoscopic anatomic lung resection (i.e. lobectomy, segmentectomy or bilobectomy) between 1 January 2012 and 1 August 2017 at our institution. We explored the risk factors for surgical conversion and adverse events occurring in patients who underwent conversion to thoracotomy. Results: A total of 44/501 patients underwent conversion during the procedure (global rate: 8.8%). The main reasons for conversion were (i) anatomical variation, adhesions or unexpected tumour extension (37%), followed by (ii) vascular causes (30%) and (iii) unexpected lymph node invasion (20%). The least common reason for conversion was technical failure (13%). We could not identify any specific risk factors for conversion. The global complication rate was significantly higher in converted patients (40.9%) than in complete VATS patients (16.8%) (P = 0.001). Postoperative atrial fibrillation was a major complication in converted patients (18.2%) [odds ratio (OR) 5.09, 95% confidence interval (CI) 1.80-13.27; P = 0.001]. Perioperative mortality was higher in the conversion group (6.8%) than in the VATS group (0.2%) (OR 33.3, 95% CI 3.4-328; P = 0.003). Conclusions: Through the years, the global conversion rate has dramatically decreased to <10%. Nevertheless, patients who undergo conversion represent a high-risk population in terms of complications (40.9% vs 16.8%) and perioperative mortality (6.8% vs 0.2%). [less ▲]

Functionally graded lattice structures (FGLS) were studied thoroughly for the past years, mostly focusing on specific synthetic tests in the context of additive manufacturing while rarely being actually applied outside of this specific domain. This paper examines a way to practically implement them in a commonly used appliance and study their potential for its improvement. A bicycle crank arm was chosen for this purpose, and a solid aluminium reference model (Shimano FC-R450-453) is used as a performance baseline. The novel design is composed of a hollow body containing a beam-based, non-stochastic, functionally graded lattice structure and is planned to be manufactured on a Markforged Metal X system using 17-4 PH stainless steel. It aims to increase the total stiffness under EN ISO 4210-8 norm loading conditions compared to the reference model while limiting mass and stress values to acceptable degrees. Two crank arm variants, containing a face-centred cubic (FCC) and re-entrant auxetic lattice respectively, are optimised by locally altering their beam radii in eight separate regions. The displacement at the load application point is minimised using Altair OptiStruct and HyperStudy. The reference crank, weighing 213g, exhibits a deflection magnitude of 7.1mm in the most demanding load case while the newly designed and optimised versions only showed displacements of 2.52mm (FCC lattice, 340g) and 2.58mm (re-entrant lattice, 339g) respectively. In addition, the stress distribution was significantly enhanced compared to the reference model, as the latter would not pass the fatigue tests required by the norm. This demonstrates that FGLS, in combination with high-strength materials and additive manufacturing, can increase the performance of many parts, although in this case, with a trade-off in terms of its mass. In future projects, it might be considerably reduced by utilising alternative lattice types lattices or other materials while preserving the benefits of FGLS. [less ▲]

Aging is a key risk factor for chronic diseases of the elderly. MicroRNAs regulate post-transcriptional gene silencing through base-pair binding on their target mRNAs. We identified nonlinear changes in age-related microRNAs by analyzing whole blood from 1334 healthy individuals. We observed a larger influence of the age as compared to the sex and provide evidence for a shift to the 5' mature form of miRNAs in healthy aging. The addition of 3059 diseased patients uncovered pan-disease and disease-specific alterations in aging profiles. Disease biomarker sets for all diseases were different between young and old patients. Computational deconvolution of whole-blood miRNAs into blood cell types suggests that cell intrinsic gene expression changes may impart greater significance than cell abundance changes to the whole blood miRNA profile. Altogether, these data provide a foundation for understanding the relationship between healthy aging and disease, and for the development of age-specific disease biomarkers. [less ▲]

This paper sets out to recontextualise the memory of rescue as it pertains to Dutch Jewry during the Holocaust, by focusing on the helpers of Anne Frank and the other Jews in hiding in the Secret Annex. Much in the same way as perceptions of Jews in hiding have been decisively shaped by the story of Anne Frank, not only in the Dutch public imagination but arguably globally, so too the image of help, at least in the Western European and Anglosaxon world, has been considerably shaped by the story of two of the five helpers, Miep and Jan Gies, even if the support they provided to the onderduikers in the Secret Annex could ultimately not prevent discovery. The question of help, as well as the ultimate betrayal, of the onderduikers are linked to the broader question of the role of the Dutch population during the Holocaust. Within that context the Anne Frank story can and has indeed been used to provide both a stereotypical image of Gentile betrayal as well as an idealized and, arguably, romanticized image of Gentile help. In this paper I will trace the ways in which the image of help and rescue of Dutch Jews was shaped by the story of, especially, Miep Gies and analyse the ways in which her story resonated in the Netherlands as well as abroad. Important moments in this regard were the recognition of Miep Gies and the other helpers as Righteous Among the Nations in 1972, and the global publication of Miep Gies’ memoirs in 1987. I will frame this analysis within the broader historical context of 1) help provided to Jews in hiding in the Netherlands and the question of how representative the ‘helpers of Anne Frank’ were, and 2) the extent to which a focus on a few key individuals obscures the more complex reality of how rescue functioned in the first place.

Structural health monitoring of concrete bridges can be achieved by tracking static load-testing results or dynamic properties as for example eigenfrequencies. Deviations from a healthy reference state can be used as damage indicators and even more, help to localize zones of stiffness reduction, i.e. cracking. However, outdoor temperature effects also lead to changes of monitored physical characteristics in the same order of magnitude as damage. Hence, temperature effects need to be removed prior to any condition analysis. The present paper presents a new two-step approach by applying physical compensation first, before using a statistical method based of Principal Component Analysis (PCA) or more exactly on principal vectors and singular values. This technique is here applied to eigenfrequencies, first of a new bridge without damage, but with extreme temperature variation due to thick asphalt layer and special bearing constraints, thus showing strong sensitivity along seasonal temperatures in the intact state. The second object is the Z24 Bridge in Switzerland, which is well documented in literature and where artificial damage was applied prior to demolition. The proposed techniques allow removing noise and temperature effects in a coherent and efficient way. The corrected measurement data can then be used in subsequent steps for its definite purpose, i.e. detection and localization of damage for instance by updating a numerical finite element model which allows assessing a stiffness loss.

Heiru gëtt kloer, dass déi un der Muecht sech dacks ouni Erfolleg ëm d’Gonscht vun der musizéierender Bevëlkerung beméit hunn a mat wéi engen drastesche Mëttelen si Veräiner begéint sinn, déi net noginn hunn. Am musekssoziologeschen Deel vun der Konferenz gëtt d’Museksveräinsliewen nom Zweete Weltkrich thematiséiert. Den Neiufank no de Krichsjoren huet de Veräiner eng nei Beléiftheet bruecht, déi souguer déi aus der Grënnungszäit iwwertraff huet. Dozou koum, dass d’Aarbechter aus den Industriegebidder am Süde vum Land an de Museken an de Chéier en intellektuellen Ausgläich zu hirer kierperlecher Aarbecht fonnt hunn. De kënschtlereschen Niveau vun de verschiddene Gesellschafte gouf zu engem iwwerregionale Virbild.
