In conventional MIMO, propagation conditions are often considered wide-sense stationary over the entire antenna array. In massive MIMO systems, where arrays can span over large physical dimensions, the situation is quite different. For instance, significant variations in signal strength, due to shadowing, can be experienced across a large array. These effects vary with propagation environment in w

Allergic asthma is characterized by eosinophilic inflammation and airway obstruction. There is also an increased risk of pulmonary infection caused by Streptococcus pneumoniae, in particular during severe asthma where high levels of the glycoprotein, osteopontin (OPN) are present in the airways. Eosinophils can be recruited by chemokines activating the receptor CCR3 including eotaxin-1/CCL11, eota

An experiment has been performed to study excited states in the neutron-deficient nucleus Ir175 via the use of the JUROGAM II high-purity germanium detector array and the RITU gas-filled separator at JYFL, Jyväskylä. By using isomer tagging, an isomeric state with a half-life of 6.58(15) μs has been observed in Ir175 for the first time. It has been established that the isomer decays via a 45.2 (E1

Do virtual representations, intended for teaching and learning, afford different constraints and affordances compared to their physical twins, and may this lead to different ways of interaction and understanding? In this line of inquiry, and with the perspective on learning as an extended activity, where learning can be mediated through the interaction with artefacts, the present study has transla

Design procedures of Jaumann and circuit analog absorbers are mostly formulated for normal angle of incidence. Only a few design methods considering oblique angle of incidence are published. The published methods are restricted to single resistive layer circuit analog absorbers or multilayered Jaumann absorbers with low permittivity spacers. General design procedures are developed in this paper fo

Supported Iridium pincer complexes were used to study gas-phase isopropanol dehydrogenation under continuous flow system at temperatures 200-260 °C with different flow rates. First supported catalyst was [Ir(C2H4)(p-tBu2PO-tBu4POCOP)] supported by covalent bonding to silica, the second one was [Ir(HCl)(p-HO2C- tBu4POCOP)] supported by adsorption to γ-Alumina. The highest activity of catalyst 1 w

ZONA – Music at the Threshold A Listening Room at the ThresholdZONA – Music at the Threshold (2021–24) is a one-hour suite of 14 pieces of electroacoustic music, born within the larger artistic journey Zonen – a long-term collaboration between artist, actor, and director Nina Jeppsson and composer Kent Olofsson. Out of this wide-reaching process have emerged a stage work, musical compositions, and
