Citizen Science has become a vital source for data collection when the spatial and temporal extent of a project makes it too expensive to send experts into the field. However, involving citizens can go further than that – participatory projects focusing on subjective parameters can fill in the gap between local community needs and stakeholder approaches to tackle key social and environmental issues. The Horizon 2020 project, LandSense, is building a modern citizen observatory for Land Use & Land Cover (LULC) monitoring, by engaging citizens to transform current approaches to environmental decision making. Citizen Observatories are community-driven mechanisms to complement existing environmental monitoring systems and can be fostered through mobile and web applications, allowing citizens to play a key role in environmental monitoring. Within this project, the City Oases mobile application, focused on the city of Vienna, has been developed that aims not only to stimulate civic engagement to monitor changes within the urban environment, but also to enable users to drive improvements by providing city planners with information about the public perception of urban spaces. City Oases was launched in March 2019. Where are the best places for a romantic date? Where can you skate? Where is it cool on a hot summer’s day? Open urban spaces can be used in many ways. Pick an activity in the CityOases app and we show the spots where you can do them, including the rating of previous users and pictures from the location. If you visit the spot you can rate it as well based on a few selected subjective criteria. If you know a cool spot that is openly accessible but not marked in our map yet? Just add it with a list of activities and some pictures. Additionally, you can input your perceptions including whether it is noisy, clean or if the infrastructure is attractive. The picture module within the application promotes you to take photos in the four cardinal directions. Users can search for specific activities, visit one of the points indicated on the map and then evaluate this point.

We investigate the wavelet spaces Wg(Hπ)⊂L2(G) arising from square integrable representations π:G→U(Hπ) of a locally compact group G. We show that the wavelet spaces are rigid in the sense that non-trivial intersection between them imposes strong restrictions. Moreover, we use this to derive consequences for wavelet transforms related to convexity and functions of positive type. Motivated by the reproducing kernel Hilbert space structure of wavelet spaces we examine an interpolation problem. In the setting of time–frequency analysis, this problem turns out to be equivalent to the HRT-conjecture. Finally, we consider the problem of whether all the wavelet spaces Wg(Hπ) of a locally compact group G collectively exhaust the ambient space L2(G). We show that the answer is affirmative for compact groups, while negative for the reduced Heisenberg group.

Promocijas darbs izstrādāts: Rīgas Stradiņa universitātē, Paula Stradiņa Klīniskās universitātes slimnīcas Neiroloģijas klīnikā, Asinsvadu ķirurģijas centrā un Latvijas Kardioloģijas centrā. Aizstāvēšana: 2020. gada 16. jūnijā plkst. 14.00 gan Rīgas Stradiņa universitātes Medicīnas promocijas padomes atklātā sēdē Rīgā, Dzirciema ielā 16, Hipokrāta auditorijā, gan attālināti Zoom tiešsaistes platformā. Miega artērijas stenoze ir nozīmīgs išēmiska insulta riska faktors. Aptuveni 10–15% gadījumu išēmisks insults rodas trombembolijas dēļ no iepriekš asimptomātiskas iekšējās miega artērijas > 50% stenozes. Pacientiem pēc pārciesta išēmiska insulta ir ne tikai fiziski funkcionāli ierobežojumi, bet bieži attīstās arī kognitīvi traucējumi un vaskulāra depresija. Tieši pēdējo desmit gadu laikā ir pieaugusi interese par nozīmīgas miega artērijas stenozes izraisītiem “neklasiskajiem” neiroloģiskajiem simptomiem un to saistību ar dzīves kvalitāti, kā arī revaskularizācijas ietekmi uz šo simptomu attīstību. Promocijas darbs “Ar veselību saistītas dzīves kvalitātes izmaiņas pēc nozīmīgas miega artērijas stenozes ārstēšanas” veltīts kopējās kognitīvās funkcijas, depresijas simptomu un dzīves kvalitātes izpētei, jo mūsdienīgas nozīmīgas miega artērijas stenozes ārstēšanas mērķis ir ne tikai samazināt išēmiska insulta risku un pagarināt dzīvildzi, bet arī nodrošināt pietiekoši labu ar veselību saistītu dzīves kvalitāti ilgtermiņā kopumā. Promocijas darba mērķis bija izpētīt kognitīvās funkcijas un ar veselību saistītas dzīves kvalitātes izmaiņas, depresijas simptomu dinamiku, kā arī precizēt cerebrovaskulāro notikumu un mirstības biežumu pacientiem, kuriem veikta nozīmīgas miega artērijas stenozes revaskularizācija vai pielietota tikai medikamentozā terapija. Pētniecības darbā tika iekļauti un analizēti 213 pacienti ar nozīmīgu miega artērijas stenozi, kuriem vai nu veica revaskularizāciju ķirurģiski vai endovaskulāri, vai arī tikai uzsāka optimālu medikamentozo terapiju bez miega artērijas revaskularizācijas. Visiem pacientiem atkārtoti novērtēja kognitīvās funkcijas, depresijas simptomu un ar veselību saistītas dzīves kvalitātes izmaiņas gada laikā. Pētījuma rezultāti liecina, ka nozīmīgas miega artērijas stenozes revaskularizācija varētu būt saistīta ar globālās kognitīvās funkcijas uzlabošanos. Savukārt depresijas simptomu izmaiņas pēc nozīmīgas miega artērijas stenozes revaskularizācijas un/vai medikamentozās ārstēšanas netika novērotas. Kopumā pacientiem gadu pēc miega artērijas endarterektomijas dzīves kvalitātes saglabājā tādā pašā līmenī kā pirms operācijas. Taču dzīves kvalitātes izmaiņu novērtēšanu pēc miega artērijas stentēšanas un medikamentozās ārstēšanas ietekmēja dažādi klīniskie parametri šajās grupās, tāpēc pārliecinošus secinājumus šobrīd veikt nav iespējams.

Background National Influenza Centers (NICs) have played a crucial role in the surveillance of SARS-CoV-2. The FluCov project, covering 22 countries, was initiated to monitor the impact of the SARS-CoV-2 pandemic on influenza activity. Methods This project consisted of an epidemiological bulletin and NIC survey. The survey, designed to assess the impact of the pandemic on the influenza surveillance system, was shared with 36 NICs located across 22 countries. NICs were invited to reply between November 2021 and March 2022. Results We received 18 responses from NICs in 14 countries. Most NICs (76%) indicated that the number of samples tested for influenza decreased. Yet, many NICs (60%) were able to increase their laboratory testing capacity and the "robustness" (e.g., number of sentinel sites) (59%) of their surveillance systems. In addition, sample sources (e.g., hospital or outpatient setting) shifted. All NICs reported a higher burden of work following the onset of the pandemic, with some NICs hiring additional staff or partial outsourcing to other institutes or departments. Many NICs anticipate the future integration of SARS-CoV-2 surveillance into the existing respiratory surveillance system. Discussion The survey shows the profound impact of SARS-CoV-2 on national influenza surveillance in the first 27 months of the pandemic. Surveillance activities were temporarily disrupted, whilst priority was given to SARS-CoV-2. However, most NICs have shown rapid adaptive capacity underlining the importance of strong national influenza surveillance systems. These developments have the potential to benefit global respiratory surveillance in the years to come; however, questions about sustainability remain.
