To better predict the timely variation of algal blooms and other vital factors for safer drinking water production, a new AI scanning–focusing process was investigated for improving the simulation and prediction of algae counts. With a feedforward neural network (FNN) as a base, nerve cell numbers in the hidden layer and the permutation and combination of factors, etc., were fully scanned to selec
Sivakumar et al. (2000a), by employing the correlation dimension method, provided preliminary evidence of the existence of chaos in the monthly rainfall-runoff process at the Göta basin in Sweden. The present study verifies and supports the earlier results and strengthens such evidence. The study analyses the monthly rainfall, runoff and runoff coefficient series using the nonlinear prediction met
To investigate the influence of gas injection timing (GIT) on the combustion instability of a premixed natural gas engine, experiments were conducted under low load conditions using various GITs. Multifractal and multiscale entropy analyses were employed to examine the fractal characteristics and complexity of the experimental time series for indicated mean effective pressure (IMEP) and heat relea
Lipid nanoparticles (LNPs) are the most versatile and successful gene delivery systems, notably highlighted by their use in vaccines against COVID-19. LNPs have a well-defined core–shell structure, each region with its own distinctive compositions, suited for a wide range of in vivo delivery applications. Here, we discuss how a detailed knowledge of LNP structure can guide LNP formulation to impro
The suitability of Hansen solubility parameters as descriptors for modelling analyte retention during reversed-phase chromatographic experiments was investigated. A novel theoretical model using Hansen solubility parameters as the basis for a complete mathematical derivation of the model was developed. The theoretical model also includes the cavitation volumes of the analytes, which were calculate
Aftershock rates seem to follow a power law decay, but the assessment of the aftershock frequency immediately after an earthquake, as well as during the evolution of a seismic excitation remains a demand for the imminent seismic hazard. The purpose of this work is to study the temporal distribution of triggered earthquakes in short time scales following a strong event, and thus a multiple seismic
Despite the recent experimental and theoretical progress in the investigation of the nuclear fission process, a complete description still represents a challenge in nuclear physics because it is a very complex dynamical process, whose description involves the coupling between intrinsic and collective degrees of freedom, as well as different quantum-mechanical phenomena. To improve on the existing
The Harmonized Parabolic Synthesis methodology is a further development of the Parabolic Synthesis methodology for approximation of unary functions such as trigonometric functions, logarithms and the square root with moderate accuracy for ASIC implementation. These functions are extensively used in computer graphics, communication systems and many other application areas. For these high-speed appl
Rheumatoid arthritis (RA) is an autoimmune disease of unknown etiology. A characteristic feature of RA is the presence of anti-citrullinated protein antibodies (ACPA). Since ACPAs are highly specific for RA and are often present before the onset of RA symptoms, they have become valuable diagnostic and prognostic. As a result, several assays for detection of ACPAs exist, which vary in sensitivity a
A new three-parameter (valency, ion size, and charge asymmetry) model, the asymmetric restricted primitive model (ARPM) of ionic liquids, has recently been proposed. Given that ionic liquids generally are composed of monovalent species, the ARPM effectively reduces to a two-parameter model. Monte Carlo (MC) simulations have demonstrated that the ARPM is able to reproduce key properties of room tem
Post-compression of (sub)-picosecond laser pulses down to sub-100 fs durations has become a standard approach for high-peak-power sources at a high average power [1]. Here, we propose a new post-compression geometry suited for extreme temporal compression of energetic narrowband lasers, such as diode or electrically pumped four-level systems which can deliver kW-average powers [2], but typically e
Re and Os concentrations and isotopic composition were analysed in four ultramafic cumulates from the Kedum tectonic lens within the Mylonite Zone, SW Sweden. An 1887±36 Ma isochron is obtained for six samples and interpreted to date the Kedum body. This is significantly older than the -1600-1700 Ma surrounding crust and the first rocks of Svecofennian age west of the Trans Scandinavian Igneous Be
This article presents and discusses results from an exercise in comparative content analysis of news articles about issues of conflict produced by Afghan journalists before and after participating in an internationally sponsored training and mentorship programme in Peace Journalism. The programme was part of a Preventing Violent Extremism (PVE) project, intended to create community resources for r
Denna avhandling utforskar möjligheter och utmaningar för bildandet av transnationell feministisk solidaritet i Mellanöstern, med fokus på Egypten och Tunisien. Avhandlingen fokuserar på feministiska organisationers arbete med att bygga transnationella allianser och stödnätverk. Mer konkret utforskas hur detta arbete balanseras med önskan om att förbli förankrade på lokal nivå och centrera lokala This dissertation explores possibilities and challenges to the formation of transnational feminist solidarity in the Middle Eastern context, focusing on Egypt and Tunisia. In particular, it asks how feminist organisations balance the work towards building transnational alliances and support networks with the imperative to remain grounded at the local level and centre local communities in their wor
We investigate the young stellar cluster population of M51 and how it is affected by encounters with giant molecular clouds (GMCs). We combine a galactic model with N-body simulations of 5000 unique clusters in the mass range [600-24000] M⊙. We simulate each cluster twice: with (CR) and without (CN) tidal perturbations from the GMCs. We are able to reproduce the majority of the observed mass- and
