After their first appearance in the cryptographic community ten years ago, cryptographic accumulators have received a discontinuous attention from the researchers of the field. Although occasionally studied, there has been no systematic effort to organize the knowledge of the subject, abstracting away from the unnecessary details of specific proposals, so as to provide a reliable starting point...

Here, the authors report results of their study on key characteristics microscale periodic Ni-Mg-Ni-Mg film structures as metal-hydride hydrogen accumulators, namely, microstructure, phase state, operation temperatures and rate sorption/desorption processes, complete reversible mass content hydrogen, enthalpy metal hydrides’ phase-formation. The has shown that hydride-formation films can be sat...

We propose a linear ballistic accumulator (LBA) model of decision making and reaction time. The LBA is simpler than other models of choice response time, with independent accumulators that race towards a common response threshold. Activity in the accumulators increases in a linear and deterministic manner. The simplicity of the model allows complete analytic solutions for choices between any nu...

This study evaluated the ability and mechanisms of 19 Pteris and non-Pteris species to accumulate arsenic (As) in a hydroponic system spiked with 300 microM As. The study included four Pteris vittata accessions (China, India, Poland, and the United Kingdom), P. biaurita and 17 non-Pteris species. Among the accessions, P. vittata from China and UK were the most and the least efficient in terms o...

Drought stress reduces annual global wheat yields by 20%. Silicon (Si) fertilisation has been proposed to improve plant drought tolerance. However, it is currently unknown if and how Si affects different landraces, especially with respect their innate accumulation properties. In this study, significant consistent differences in between landraces were identified, allowing for the classification ...
