In this paper we study two major challenges in few-shot bioacoustic event detection: variable event lengths and false-positives. We use prototypical networks where the embedding function is trained using a multi-label sound event detection model instead of using episodic training as the proxy task on the provided training dataset. This is motivated by polyphonic sound events being present in the b

Most pretreatment risk-assessment models to predict biochemical recurrence (BCR) after radical prostatectomy (RP) for prostate cancer rely on total prostate-specific antigen (PSA), clinical stage, and biopsy Gleason grade. We investigated whether free PSA (fPSA) and human glandular kallikrein-2 (hK2) would enhance the predictive accuracy of this standard model. Preoperative serum samples and compl

The expansion of the European Union’s (EU) regulatory sphere creates conflicts of sovereignty between the EU and its member states, and third countries that lack a possibility to participate in the making of those laws and policies. The conflict is epitomised in the concept of the Union’s decision-making autonomy. Albeit stringently applied, the concept is ambiguous and undefined. This article end

Studying migrants from Sweden to the United States, we provide new evidence on return migration during the Age of Mass Migration. Focusing on a sample of migrants and stayers observed in childhood, we document limited effects on income and occupational upgrading, but large effects on wealth. Male returnees held about twice as much wealth as stayers and about 40 percent more than staying brothers.

The transformation of the energy systems will call for new turbomachinery designs for harvesting low-grade heat. The word “low-grade” has many definitions and ranges from levels where steam is the preferred selection to very low grades where specially adopted ORC technology is used. In this work, turbomachinery for cascading the steam cycle with a very low-temperature ORC technology is studied. Th

Background: The aims of this study are to 1) determine the scope of musculoskeletal (MSK)-related clinical research in Sweden; 2) collate the amount of first-tier funding received; 3) discuss strategies and infrastructure supporting future MSK clinical trials in Sweden. Methods: A systematic scoping review protocol was applied in PubMed, Scopus, and SweCRIS databases. The articles were examined, a

The distinction between primary and secondary iconic signs, which I first made with regard to pictures, has been applied by other scholars to language, gesture, and music. Taking stock of this process, it has become necessary to clarify the distinction, insisting on the fact that secondary iconicity is not conventionality, but a kind of iconicity which is in itself not sufficient to define a meani

Existing state-of-the-art estimation systems can detect 2d poses of multiple people in images quite reliably. In contrast, 3d pose estimation from a single image is ill-posed due to occlusion and depth ambiguities. Assuming access to multiple cameras, or given an active system able to position itself to observe the scene from multiple viewpoints, reconstructing 3d pose from 2d measurements becomes

The management and conservation of lakes should be conducted in the context of catchments because lakes collect water and materials from their upstream catchments. Thus, the datasets of catchment-level characteristics are essential for limnology studies. Lakes are widely spread on the Tibetan Plateau (TP), with a total lake area exceeding 50000km2, accounting for more than half of the total lake a

Background: Recent findings have shown that imaging voluntarily activated motor units (MUs) by decomposing ultrasound-based displacement images provides estimates of unfused tetanic signals evoked by spinal motoneurons’ neural discharges (spikes). Two methods have been suggested to estimate its spike trains: band-pass filter (BPM) and Haar wavelet transform (HWM). However, the methods’ optimal par

This paper shows that the socio-technical barriers that sustainable innovations face, may stem from global regimes. Existing transitions approaches like the Technological Innovation System (TIS), overlook the impact of global regimes on radical innovation. Building on institutional theory, we therefore develop a theoretical framework that captures TIS-regime interaction, allowing us to analyze the

Freshwater scarcity is a vital societal challenge related to climate change, population pressure, and agricultural and industrial demands. Therefore, sustainable desalination/purification of salty/contaminated water for human uses is particularly relevant. Membrane distillation is an emerging hybrid thermal-membrane technology with the potential to overcome the drawbacks of conventional desalinati

Membrane-based photothermal crystallization - a pioneering technology for mining valuable minerals from seawater and brines - exploits self-heating nanostructured interfaces to boost water evaporation, so achieving a controlled supersaturation environment that promotes the nucleation and growth of salts. This work explores, for the first time, the use of two-dimensional graphene thin films (2D-G)

The recovery of raw materials represents one of the greatest challenges for a circular economy. Especially, the increased demand for lithium in the last years for its critical role in Li-ion batteries implies the need for green technology for Li recovery able to address market requests. Here, we devise and implement a new technology exploiting excitons-based light-to-heat conversion promoted by WS

Dementia have substantial negative impact on the affected individual, their care partners and society. Persons living with Parkinson’s disease (PwP) are also to a large extent living with dementia. The aim of this study is to estimate time to dementia in PD using data from a large quality register with access to baseline clinical and patient reported data merged with Swedish national health regist

Background: Gangliogliomas are brain tumors associated with drug-resistant focal epilepsy. In most cases, seizures improve after surgical treatment. It is still not concluded to what extent the lesion itself or the perilesional area contributes to the epileptogenicity. Case presentation: In the case presented in this report, the patient, a 24-year-old Caucasian male, developed a refractory status

Postprandial insulinaemia, triglyceridaemia and measures of inflammation are thought to be more closely associated with cardiovascular risk than fasting measures. Although hypertension is associated with altered fasting metabolism, it is unknown as to what extent postprandial lipaemic and inflammatory metabolic responses differ between hypertensive and normotensive individuals. Linear models adjus
