The time dependent Maxwell system is supplemented with the constitutive relations of linear bianisotropc media and is treated as a neutral integro-differential equation in a Hilbert space. By using the theory of abstract Volterra equations and strongly continuous semigroups we obtain general well-posedness results for the corresponding mathematical problem.
The Universal Thermal Climate Index (UTCI) aimed for a one-dimensional quantity adequately reflecting the human physiological reaction to the multi-dimensionally defined actual outdoor thermal environment. The human reaction was simulated by the UTCI-Fiala multi-node model of human thermoregulation, which was integrated with an adaptive clothing model. Following the concept of an equivalent temper
The CALIFA calorimeter is an advanced detector for gamma rays and light charged particles, accordingly optimized for the demanding requirements of the physics programme proposed for the (RB)-B-3 facility at FAIR. The multipurpose character of CALIFA is required to fulfil challenging demands in energy resolution (5-6% at 1 MeV for gamma rays) and efficiency. Charged particles, e.g. protons of energ
Earlier work has derived the storage complexity of the bounded distance decoder (BDD) for binary-channel convolutional codes. We extend this work to the Gaussian noise channel and to partial-response codes. We show that the storage requirement similar to(2(1-R) - 1)(-t) paths for rate-R convolutional codes over the binary channel becomes similar to2(2Rt) over the Gaussian channel, where the decode
We report on large scale ab initio calculation for the 4s(2) S-1(0)-4s4p P-1,3(0,1,2) transitions in the zinc-like sequence, using the multiconfiguration Dirac Fock ( MCDF) method. Our attention is focused on the spin-forbidden transition 4s(2) S-1(0)-4s4p P-3(1) and the hyperfine- induced ( HPF) transition 4s(2) S-1(0)-4s4p P-3(0) for ions between Z = 30 ( Zn) and Z = 47 ( Ag). Our results provid
This paper explores the concept of Value-at-Risk (VaR) through a comparative study of nonparametric and parametric models in order to find the best risk model for banks’ trading portfolios. The non-parametric methods consist of three different approaches: Simple Historical Simulation, Age Weighted Historical Simulation and Volatility Weighted Historical Simulation by means of the EWMA and GARCH mo
Det kan inte ha undgått någon att USA drabbats av en mental växthuseffekt. Den politiska hettan är besvärande, debattklimatet minner om rötmånad och giftalgerna sipprar ut i omvärlden. Mot den bakgrunden är det intressant att följa den amerikanska högerns långsiktiga utveckling för att få perspektiv på hur det har kunnat gå så illa. Det finns förvisso redan en sån litteratur, även på svenska. Jag
Background and Hypothesis: To clarify whether the familial liability to psychosis associated with bipolar disorder (BD) is nonspecific or has a greater effect on risk for psychosis in cases with prominent mood symptoms and/or a remitting course. Study Design: We examined, in 984 809 offspring raised in intact families in Sweden, born 1980-1996 and followed-up through 2018, by multivariable Cox pro
We have developed a sampling method for beamline simulations for the proposed NNBAR experiment at the European Spallation Source. The method is based on probability density evaluation and duct source biasing and enables the simulations of the entire NNBAR beamline with high statistics while also preserving correlations of the neutron tracks. Future efforts will focus on employing these methods for
Cobalt (Co) nanoparticles (NPs) may be diffusely dispersed into natural ecosystems from various anthropogenic sources such as traffic settings and eventually end up in aquatic systems. As environmentally dispersed Co NPs may be transferred through an aquatic food web, this study investigated this transfer from algae (Scendesmus sp.) to zooplankton (Daphnia magna) to fish (Crucian carp, Carassius cCobalt (Co) nanoparticles (NPs) may be diffusely dispersed into natural ecosystems from various anthropogenic sources such as traffic settings and eventually end up in aquatic systems.

For the Phase-II Upgrade of the ATLAS Detector [1], its Inner Detector, consisting of silicon pixel, silicon strip and transition radiation sub-detectors, will be replaced with an all new 100% silicon tracker, composed of a pixel tracker at inner radii and a strip tracker at outer radii. The future ATLAS strip tracker will include 11,000 silicon sensor modules in the central region (barrel) and 7,
This chapter is centered on the importance of letting learners take the lead in their lifelong educational journey, meeting the challenges that they encounter. Additionally, the chapter focuses on new modes of learning in the digital era. The role transfers and professional development of managers, leaders, and academics are discussed, as well as the need for the development of digital academic sc
Several recent studies of solar twins in the solar neighbourhood have shown a tight correlation between various elemental abundances and age, in particular [Y/Mg]. If this relation is real and valid for other types of stars as well as elsewhere in the Galaxy, it would provide a very powerful tool to derive ages of stars without the need to resort to determining their masses (evolutionary stage) ve
