In a wireless communication system, the radio propagation channel is a complicated component to characterise. Channel sounding equipment thus has to meet specific criteria to extract the desired channel parameters. In this study, the authors outline the development and validation of a vector network analyser (VNA) based channel sounder for the frequency range from 1 to 50 GHz using radio-over-fibr
Patients with immune-mediated kidney diseases are at increased risk of severe coronavirus disease 2019 (COVID-19). The international rollout of COVID-19 vaccines has provided varying degrees of protection and enabled the understanding of vaccine efficacy and safety. The immune response to COVID-19 vaccines is lower in most patients with immune-mediated kidney diseases; either related to immunosupp
In this intervention, we call for extending the critical lens of intersectionality to the field of climate justice. We do so by identifying the theoretical and methodological links through which intersectionality can benefit climate change studies. These include common roots in radical theory, a focus on marginalized populations, challenging dominant epistemologies and ontologies, similar strategi
A simple and inexpensive amperometric biosensor for formate detection was obtained by immobilization of for-mate dehydrogenase (FDH) on graphite powder, modified with a new phenothiazine derivative (DDDP; 16H, 18H-dibenzo[c,l]-7,9-dithia-16,18-diazapentacene). Two different enzyme environments were used: FDH was adsorbed on DDDP-modified graphite powder in the presence of polyethylenimine (PEI) as
Preliminary results from the first experiment of the Stopped Beam RISING campaign are presented. The relativistic projectile fragmentation of a 750 MeV/u beam of Ag-107 populated isomeric states in very neutron deficient nuclei at the proton dripline around mass 80-90. Nuclei were unambiguously identified using the FRagment Separator (FRS) and its ancillary detectors located at GSI. The ions produ
Recently, the multiplexing efficiency metric is proposed for characterizing the MIMO performance of terminal antennas. Here, we show that it can also provide useful insights into the impact of user on MIMO terminal performance. In particular, the impact of user hand and head on the efficiency and correlation of a MIMO antenna can be conveniently quantified using the multiplexing efficiency metric.
The FIR function of the proposed filter is realized by integrating weighted signal currents in a given time window on a capacitor The input signal voltage is weighted into multiple voltages according to the FIR requirement through a resistor ladder. A switching network sequentially connects the weighted voltages to a linear transconductor which converts the voltage to current and charges the capac
Under efterkrigstiden har statliga verk utlokaliserats från Stockholm. I början av 1970-talet förlades flera av dem till Jönköping, bl.a. Lantbruksstyrelsen, Skogsstyrelsen, Statens jordbruksnämnd och Domstolsverket.
Utifrån en av Brenda Brasher (1998) gjord sociologisk undersökning av två amerikanska kristna fundamentalistiska församlingar diskuterar Appelros om det, som Brasher menar, är rimligt att förstå den där förekommande exklusivt kvinnliga verksamheten som ett befriande och bemyndigande forum för kvinnlig maktutövning. I artikeln argumenteras för att denna verksamhet snarare bör förstås som ett led i
Abstract in UndeterminedWarfare and legitimate violence have long been seen as key elements in state formation. Persistent Piracy brings into the picture the long missing component of maritime violence – and shows it to be of vital importance to the formation and, on occasion, disintegration, of states. Spanning from the Caribbean to East Asia and covering almost 3,000 years of history, from Class
