Discussion on social media and their contribution to democratisation is dominated by scholarship on the use of social media in mobilizing and coordinating grassroots opposition in contentious movements (e.g., the Arab Spring). Such approach, however, fails to recognize the power dynamics underlying everyday uses of social media. To fill this gap, this article provides one of the first studies on t
The interplay between cardiac sarcoplasmic Ca2+ATPase and phospholamban is a key regulating factor of contraction and relaxation in the cardiac muscle. In heart failure, aberrations in the inhibition of sarcoplasmic Ca2+ATPase by phospholamban are associated with anomalies in cardiac functions. In experimental heart failure models, modulation of the interaction between these two proteins has been
Manufacturing test specimens, testing them in the laboratory and evaluat- ing material parameters for finite element analysis is costly and time consum- ing. In order to simplify the hyperelastic characterisation of rubber materials an extension of the standard hardness test is here proposed. A number of indentation depths are chosen for the hardness test and the indentation forces for these depth
Next generation wireless systems have to be able to efficiently deal with fast fading environments in order to achieve high spectral efficiency. Using multiple-input multiple-output (MIMO) systems and exploiting receive diversity, their spectral efficiency can be greatly increased. Commonly, the channel is estimated via training symbols, before the data detection is carried out based on the previo
Exposure to aerosol nanoparticles has always been present in the evolution of humans, and thus has the human body developed ways of dealing with particles that enters the body. However with the emerging nanotech industry, new types of nanoparticles are being produced and used. Many of these particles have properties never seen before and this rise concern about how exposure to them might cause unw
Labeling of proteins with deuterium (2H) is often necessary for structural biology tech-niques, such as neutron crystallography, NMR spectroscopy, and small-angle neutron scattering. Perdeuteration in which all protium (1H) atoms are replaced by deuterium is a costly process. Typ-ically, expression hosts are grown in a defined medium with heavy water as the solvent, which is supplemented with a de
In the summer of 1993, two Russian scientists from the Institute of Physics in Nizhny Novgorod drove the 1, 934 km to Umeå, where I was based at that time, in their red Lada car loaded with a home-built Ti:Sa laser. Within a few days, the laser was put in operation, pumped by a small argon-ion laser, and produced stable -100 fs pulses at 790 nm. These pulses were applied to our favorite topic at t
In this paper, we present a side-channel attack on a first-order masked implementation of IND-CCA secure Saber KEM. We show how to recover both the session key and the long-term secret key from 24 traces using a deep neural network created at the profiling stage. The proposed message recovery approach learns a higher-order model directly, without explicitly extracting random masks at each executio
C4b-binding protein (C4BP) is an important component in the regulation of the complement system and also binds the anticoagulant vitamin K-dependent protein S. These activities are performed by distinct, although structurally related, polypeptides of 70 kDa (alpha chain) and 45 kDa (beta chain), respectively. In this report we have investigated the genetic relationships between these polypeptides.
Radiative transfer (RT) is a key component for investigating atmospheres of planetary bodies. With the 3D nature of exoplanet atmospheres being important in giving rise to their observable properties, accurate and fast 3D methods are required to be developed to meet future multidimensional and temporal data sets. We develop an open-source GPU RT code, gCMCRT, a Monte Carlo RT forward model for gen
The role of public transport in society is crucial, particularly for those who do not have access to alternative transport modes. For public transport to be able to fulfil its societal role, it should not be perceived as unsafe or unhealthy by its (potential) users. Several studies from all over the world have shown that anxiety has increased remarkably during the pandemic, and it is likely to las
Introduction: Further evidence is needed to support the use of plasma amyloid β (Aβ) biomarkers as Alzheimer's disease prescreening tools. This study evaluated the clinical performance and robustness of plasma Aβ42/Aβ40 for amyloid positivity prescreening. Methods: Data were collected from 333 BioFINDER and 121 Alzheimer's Disease Neuroimaging Initiative study participants. Risk and predictive val
For the proper water resources management of the Chikugo River basin, the prediction of both drought and heavy rainfall needs to be carried out by the conventional and engineering method which can be useful to for the practitioners who work on the water resources management and flood control. A relatively simple and efficient way to estimate local and regional rainfall, as well as other hydrometeo
In synchrotrons, nonuniform fill patterns, which give rise to beam phase transients and a spread in synchrotron tune between bunches, have been observed to damp longitudinal coupled-bunch instabilities driven by higher-order modes in rf cavities. The transients are especially large in the presence of Landau cavities, which are used commonly in storage-ring light sources and particularly in the new
