Formation and significance of black pebbles from the ota limestone (Upper Jurassic, Portugal)
1987
Black pebbles are a characteristic facies element of the Upper Jurassic Ota carbonate bank (Portugal). They occur both scattered or concentrated in two horizons, the upper of which is very widespread and may serve as a lithostratigraphic correlation level.
Long-term decrease in Asian monsoon rainfall and abrupt climate change events over the past 6,700 years
2021
Significance The variability of the Asian summer monsoon (ASM) is important for the functioning of ecological and societal systems at regional to continental scales, but the long-term evolution and interannual variability of this system is not well understood. Here, we present a stable isotope–based reconstruction of ASM variability covering 4680 BCE to 2011 CE. Superimposed on a gradual drying trend, a rapid drop in mean annual precipitation (>40%) toward persistently drier conditions occurred in ∼1675 BCE. This megadrought caused regional forest deterioration and enhanced aeolian activity affecting Chinese ecosystems. We argue that this abrupt aridification starting ∼2000 BCE triggered wa…
Critical Assessment of European Agenda for the Collaborative Economy, on behalf of European Parliament. In-Depth Analysis for the IMCO Committee
2017
The research paper describes the main legal challenges for regulating the collaborative economy and evaluates the definition of, and elucidates how the existing body of EU law applies to collaborative economy business models. In the last part, the paper elaborates on how a regulatory framework for non- professional provision of services and prosumers should look like and makes a few concrete proposals for future policies. This paper was commissioned by the Policy Department A for Economic, Scientific and Quality of Life Policies upon request of the European Parliament ́s Committee on the Internal Market and Consumer Protection.
Rinse, Repeat. Paratextual Poetics of Literary Twitter Collage Retweeted
2019
This essay studies what happens to the poetics of a text that was first written on or for a certain internet platform when it is later copy-pasted to a different literary medium – that of an edited and printed book. The main target of the discussion is Finnish author Karri Kokko’s conceptual literary work Retweeted (2016), a print-on-demand book, the roots of which are firmly in both the traditions of print media and the digital interfaces of the social media platform Twitter. The analysis pays close attention to the medial qualities of both Twitter and the conceptual novel that draws material from it. The essay aims to highlight the poetic qualities of the material produced and circulated …
Deregulated Splicing Is a Major Mechanism of RNA-Induced Toxicity in Huntington's Disease.
2019
Huntington's disease (HD) is caused by an expanded CAG repeat in the huntingtin (HTT) gene, translating into an elongated polyglutamine stretch. In addition to the neurotoxic mutant HTT protein, the mutant CAG repeat RNA can exert toxic functions by trapping RNA-binding proteins. While few examples of proteins that aberrantly bind to mutant HTT RNA and execute abnormal function in conjunction with the CAG repeat RNA have been described, an unbiased approach to identify the interactome of mutant HTT RNA is missing. Here, we describe the analysis of proteins that preferentially bind mutant HTT RNA using a mass spectrometry approach. We show that (I) the majority of proteins captured by mutant…
Corporate groups in platform companies

The article analyses the structure of groups of platform companies and, based on three cases, tries to demonstrate the inadequacy of their treatment in Labour and Social Security Law. The article was awarded by the organisation of the Asociación Española de Derecho del Traba…
Platforma czasopism Uniwersytetu Opolskiego przykładem synergii w budowaniu otwartego dostępu do publikacji uczelnianych
2020
Narodowe Centrum Nauki we wrześniu 2018 r. zadeklarowało udział w realizacji Planu S, który przewiduje, że od 1 stycznia 2020 r. wszystkie publikacje naukowe powstałe z udziałem finansowania ze środków publicznych muszą być publikowane w czasopismach Open Access lub na platformach Open Access. Na Uniwersytecie Opolskim trwały już wtedy prace nad uruchomieniem platformy, która zapewniłaby otwarty dostęp do uczelnianych czasopism naukowych. Docelowo umieszczono na niej trzynaście tytułów wydawanych przez uczelnię. Zadanie to powierzono do realizacji Bibliotece Głównej UO jako jednostce koordynującej wszelkie prace związane z jej powstaniem. Jest to kolejna – po repozytorium uczelnianym – form…
Datorspēļu ietekme uz cilvēka saikni ar realitāti
2022
“Just Think About It” ir starp-platformu datorspēle, kas parāda spēlētājam datorspēļu ietekmi uz cilvēka saikni ar realitāti ar biežām norādījumiem, cik ilgi spēlētājs atrodas datorspēlē, nedomājot par reālo dzīvi. Idejas pamātā ir likt spēlētājam aizdomāties, vai viņš/viņa izmanto savu laiku saprātīgi. Spēle piedāvā izmēģināt sevi divos datorspēļu dizaina žanros: 2D platformeris un 2D skatā no augšas uz lēju, jo tā sastāv no divām nodaļām, kuri ir nedaudz saistīti viens ar otru, un katrā nodaļā ir trīs apakšnodaļas ar bosu beigās. Kā arī abas nodaļas ir, tā saucamā, “roguelike” datorspēļu žanrā. Spēlē tika realizēta lokalizācija trīs valodās: Angļu, Latviešu un Krievu valodā, līdz ar to šo…
Adversarial Attack’s Impact on Machine Learning Model in Cyber-Physical Systems
2020
Deficiency of correctly implemented and robust defence leaves Internet of Things devices vulnerable to cyber threats, such as adversarial attacks. A perpetrator can utilize adversarial examples when attacking Machine Learning models used in a cloud data platform service. Adversarial examples are malicious inputs to ML-models that provide erroneous model outputs while appearing to be unmodified. This kind of attack can fool the classifier and can prevent ML-models from generalizing well and from learning high-level representation; instead, the ML-model learns superficial dataset regularity. This study focuses on investigating, detecting, and preventing adversarial attacks towards a cloud dat…
Pilsoņu likumdošanas digitālās platformas ManaBalss.lv izvērtējums
2018
Bakalaura darba temats ir “Pilsoņu likumdošanas digitālās platformas ManaBalss.lv izvērtējums”. Autors ar šī pētījuma mērķi vēlas noskaidrot, kāds ir bijis iemesls šādas kolektīvās inteliģences platformas izveidei un to, vai platforma ir sasniegusi savu dibināšanas mērķi. Darba gaitā tika noskaidrots, kas ir kolektīvā inteliģence un tās sniegtās iespējas. Ar interviju palīdzību, tika veikts ManaBalss.lv platformas izvērtējums – tās mērķis, vai mērķis ir sasniegts, vai platforma veicina pilsoņu līdzdalību demokrātiskajos procesos. Darba gaitā izvirzītā hipotēze apstiprinājās – kolektīvās inteliģences platforma ManaBalss.lv ir sasniegusi savus mērķus.
