Studying the reliability of complex systems using machine learning techniques involves facing a series of technical and practical challenges, ranging from the intrinsic nature of the system and data to the difficulties in modeling and effectively deploying models in real-world scenarios. This study compares the effectiveness of classical statistical techniques and machine learning methods for ...

The spectroscopic detection of gases and their stable isotopes holds significant value in bio-sciences and climate studies. However, achieving high precision has long been confined to bulky and costly equipment. In this work, we introduce a nanophotonic waveguide that is capable of detecting CO₂ gas down to 20 parts per billion, and for the first time perform accurate stable isotope ratio ...

På 1200-tallet ble to store mangeromsanlegg bygget mindre enn en dagsmarsj fra hverandre på nordvestkysten av Varangerhalvøya. Anleggene var i bruk samtidig over en periode på 150 år. Mye tyder på at de ble etablert av representanter for de to fremste rivaler i middelalderens maktspill om land og ressurser i nord.

Background - Fontan circulatory failure with impaired systolic function is well documented; however, its mechanisms are not fully understood. The aim of this study was to explore myocardial functional reserve in adolescent patients with Fontan circulation in response to exercise or acute preload increase.<p> <p>Methods - The study included 32 patients (median age, 16.7 years; range, 15.4–17.9 years; ...

Background During the recent years, emergency services in several countries have integrated video streaming into medical emergency calls, and research on the topic has gained increased focus. Video streaming during medical emergency calls may change dispatcher’s perspective of the call and can be a helpful tool for supervising bystanders’ first aid. Little research exists, however, about the ...

Artikkelen gir en analyse og kritisk vurdering av Høyesteretts resonnementer og standpunkter i Ramme-saken. Forfatterne er særlig kritiske til standpunktet om at også avkastning av egenkapital må dekkes av overskuddsevnen, og de mener at standpunktet har så problematiske konsekvenser på inntekts-/omset- ningssiden at spørsmålet neppe kan anses endelig avklart ved dommen. Forfat- terne mener at det ...

Within linguistic theory, the division of labour between syntax and the lexicon has been a central issue for debate among different architectures of grammar, roughly corresponding to the distinction between memorization and rule governed aspects of language competence. In this article, I give some historical context for these debates, concluding that differences in architectural assumptions are ...

Quality parameters and storage stability were evaluated through biochemical, textural, and microbial analyses of the Norwegian red sea cucumber Parastichopus tremulus at two different storage temperatures (0 °C and 4 °C) over 17 days. During storage, the pH decreased from 7 to 6.3, the texture became softer decreasing from 47.3 to 0.3 N, while K-value increased from 4 to 52 %, microbial counts ...

This study explores the thermal conductivity and viscosity of water-based nanofluids containing silicon dioxide, graphene oxide, titanium dioxide, and their hybrids across various concentrations (0 to 1 vol%) and temperatures (30 to 60 °C). The nanofluids, characterized using multiple methods, exhibited increased viscosity and thermal conductivity compared to water, with hybrid nanofluids ...

The proliferation of healthcare data has expanded opportunities for collaborative research, yet stringent privacy regulations hinder pooling sensitive patient records. We propose a \emph{multiparty homomorphic encryption-based} framework for \emph{privacy-preserving federated Kaplan--Meier survival analysis}, offering native floating-point support, a theoretical model, and explicit reconstruction-attack ...
