- Global impact models represent process-level understanding of how natural and human systems may be affected by climate change. Their projections are used in integrated assessments of climate change. Here we test, for the first time, systematically across many important systems, how well such impact models capture the impacts of extreme climate conditions. Using the 2003 European heat wave and drought as a historical analogue for comparable events in the future, we find that a majority of models underestimate the extremeness of impacts in important sectors such as agriculture, terrestrial ecosystems, and heat-related human mortality, while impacts on water resources and hydropower are overestimated in some river basins; and the spread across models is often large. This has important implications for economic assessments of climate change impacts that rely on these models. It also means that societal risks from future extreme events may be greater than previously thought.

- GRB 221009A is the brightest Gamma Ray Burst (GRB) ever observed. The observed extremelyhigh flux of high and very-high-energy photons provide a unique opportunity to probe the predictedneutrino counterpart to the electromagnetic emission. We have used a variety of methods to searchfor neutrinos in coincidence with the GRB over several time windows during the precursor, promptand afterglow phases of the GRB. MeV scale neutrinos are studied using photo-multiplier ratescalers which are normally used to search for galactic core-collapse supernovae neutrinos. GeVneutrinos are searched starting with DeepCore triggers. These events don’t have directionallocalization, but instead can indicate an excess in the rate of events. 10 GeV - 1 TeV and >TeVneutrinos are searched using traditional neutrino point source methods which take into accountthe direction and time of events with DeepCore and the entire IceCube detector respectively. The>TeV results include both a fast-response analysis conducted by IceCube in real-time with timewindows of T0 − 1 to T0 + 2 hours and T0 ± 1 day around the time of GRB 221009A, as well asan offline analysis with 3 new time windows up to a time window of T0 − 1 to T0 + 14 days, thelongest time period we consider. The combination of observations by IceCube covers 9 ordersof magnitude in neutrino energy, from MeV to PeV, placing upper limits across the range forpredicted neutrino emission.

- Progressive Web Apps (PWAs) are a promising approach for developing mobile apps, especially when developing apps for multiple mobile systems. As mobile devices are limited with respect to battery capacity, developers should keep the energy footprint of a mobile app as low as possible. The goal of this study is to analyze the difference in energy consumption of PWAs compared to other mobile development approaches. As mobile apps are primarily interactive in nature, we focus on UI rendering and interaction scenarios. For this, we implemented five versions of the same app with different development approaches and examined their energy footprint on two Android devices with four execution scenarios. Additionally, we extended our research by analyzing multiple real-world mobile apps to include a more practical perspective. Regarding execution environments, we also compared the energy consumption of PWAs executed in different web-browsers. The results based on sample and real-world apps show that the used development approach influences the energy footprint of a mobile app. Native development shows the lowest energy consumption. PWAs, albeit having a higher energy consumption than native apps, are a viable alternative to other mobile cross-platform development (MCPD) approaches. The experiments could not assert an inherent technological disadvantage of PWAs in contrast to other MCPD approaches when considering UI energy consumption. Moreover, the web-browser engine used to execute the PWA has a significant influence on the energy footprint of the app. © 2022 Elsevier Ltd

Dietary natural products and their potential to influence health and disease including animal model studies

Forskningsöversikt (refereegranskat)abstract
- Although biological and pharmacological effects of dietary natural products have been intensively studied, there has been no bibliometric analysis performed on this research field up to now. The current study has aimed to identify and analyze the manuscripts on dietary natural products and their potential to influence health and disease including studies using animal models. Data, including words from titles and abstracts, publication and citation data, have been extracted from Web of Science database and analyzed by the VOSviewer software. Our search has yielded 1,014 manuscripts. The ratio of original articles to reviews was identified to be 1.5:1. Over half of the manuscripts have been published since 2010. The manuscripts have been contributed by 4,301 authors from 1,445 organizations in 76 countries/territories and published in 499 journals. The results from the current study point out that scientific research focusing on the potential of dietary natural products to affect health and disease status (including animal model studies) is expanding, and suggests an increasing significance of this scientific area. With the progressive development and improvement of animal studies, it should be expected that animal models of different human diseases (especially civilization ones) would be an integral part of the research for the evaluation of pharmaceuticals originated from dietary natural products like plants or plant materials. Moreover, natural products can also be fed to animals to improve the quality of animal products, with numerous resulting functional effects.
