Streamflow estimation is important in hydrology, especially in drought and flood-prone areas. Accurate estimation of streamflow values is crucial for the sustainable management of water resources, the development of early warning systems for disasters, and for various applications such as irrigation, hydropower production, dam sizing, and siltation management. This study developed the ANN algorith

HIV-2 infection will progress to AIDS in most patients without treatment, albeit at approximately half the rate of HIV-1 infection. HIV-2 capsid (p26) amino acid polymorphisms are associated with lower viral loads and enhanced processing of T cell epitopes, which may lead to protective Gag-specific T cell responses common in slower progressors. Lower virus evolutionary rates, and positive selectio

Cities have an important role to play in implementing the UN Sustainable Development Goals (SDGs) and to mobilize sustainability at the urban level. Yet, municipalities encounter challenges in localizing the SDGs into their governance structures, and there is a need to advance our understanding of cities strengths and weaknesses in such processes. In this article we provide knowledge and reflectio

This chapter presents a synthesis of the entire edited collection. In doing so, three key themes are developed which emerged from the chapter contributions. These themes are as follows: planning for climate change, second home community responses to climate change, and second home impacts on climate change. These themes are elaborated in the context of the relevant supporting chapters before the a

Whole-genome duplication has shaped the evolution of angiosperms and other organisms, and is important for many crops. Structural reorganization of chromosomes and repatterning of gene expression are frequently observed in allopolyploids, with physiological and ecological consequences. Recurrent origins from different parental populations are widespread among polyploids, resulting in an array of l

It has been a mystery that the detected fluorescence intensity of single MEH-PPV molecules is much lower than expected based on their chain length. In this review, after re-evaluating of the literature data in the light of new specially designed experiments, we present a comprehensive explanation of this issue: The actual size of MEH-PPV molecules at single molecule level is much smaller than expe

Aggregated insoluble tau is one of two defining features of Alzheimer’s disease. Because clinical symptoms are strongly correlated with tau aggregates, drug development and clinical diagnosis need cost-effective and accessible specific fluid biomarkers of tau aggregates; however, recent studies suggest that the fluid biomarkers currently available cannot specifically track tau aggregates. We show

BACKGROUND: Both COVID-19 and its associated societal restrictions have affected individuals' health and everyday life. In Sweden, more lenient public health restrictions were implemented, with individuals asked to act responsibly in terms of reducing spread of disease. The majority of studies reporting on experiences of Covid-19 restrictions have been in the context of more substantial mandatory

Understanding the molecular mechanisms of osteoarthritis (OA) is critical for early diagnosis and effective treatment. OA is a leading cause of disability and poses an increasing burden on healthcare systems, particularly with an aging global population. Despite the potential of proteomics to elucidate the complex biology underlying OA, its application remains limited due to challenges including g

Tendons are collagen-based connective tissues where the composition, structure and mechanics respond and adapt to the local mechanical environment. Adaptation to prolonged inactivity can result in stiffer tendons that are more prone to injury. However, the complex relation between reduced loading, structure, and mechanical performance is still not fully understood. This study combines mechanical t

Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. It is thus of high importance to understand the characteristics of each

We have designed a [Fe(SH)4H]− model with the fifth proton binding either to Fe or S. We show that the energy difference between these two isomers (∆E) is hard to estimate with quantum-mechanical (QM) methods. For example, different density functional theory (DFT) methods give ∆E estimates that vary by almost 140 kJ/mol, mainly depending on the amount of exact Hartree–Fock included (0%–54%). The m

Under de senaste åren har Sverige upplevt en oroande ökning av våld, inte minst särskilt riktat mot anhöriga till dem som är involverade i gäng konflikter. Denna eskalering, som beskrivs i ett nytt blogginlägg, har nått en kritisk punkt och jämförs med den metaforiska öppningen av "Pandoras ask". Situationens allvar väcker frågor om de bredare konsekvenserna för det svenska samhället och om denna In recent years, Sweden has witnessed a concerning surge in violence, not least targeting relatives of those entangled in gang-related conflicts. This escalation, which is detailed in a new blog post, has reached a critical juncture, drawing comparisons to the metaphorical opening of "Pandora's box". The gravity of the situation raises questions about the broader implications for Swedish society a

The observation of a weak proton-emission branch in the decay of the 3174keV 53mCo isomeric state marked the discovery of proton radioactivity in atomic nuclei in 1970. Here we show, based on the partial half-lives and the decay energies of the possible proton-emission branches, that the exceptionally high angular momentum barriers, lp = 9 and lp = 7, play a key role in hindering the proton radioa
