Space plasma simulations have seen an increase in the use of magnetohydrodynamic (MHD) with embedded Particle-in-Cell (PIC) models. This combined MHD-EPIC algorithm simulates some regions interest using kinetic PIC method while employing MHD description rest domain. The models are highly efficient and their fluid descriptions valid for most part computational domain, thus making large-scale glo...

The explosion of scientific results about epigenetic and other parental effects appears bewilderingly diverse. An important distinction helps to bring order to the data. Firstly, parents can detect adaptively-relevant information and transmit it to their offspring who rely on it to set a plastic phenotype adaptively. Secondly, adaptively-relevant information may be generated by a process of sel...

This work presents an Adaptively Secure Broadcast Mechanism (ASBM) based on threats analytics. It defines the security intelligence of a broadcast system comprehensively with a novel concept of collective intelligence. The algorithmic mechanism is analyzed from the perspectives of security intelligence, communication complexity and computational intelligence. The security intelligence of ASBM i...

We introduce an unsupervised approach to efficiently discover the underlying features in a data set via crowdsourcing. Our queries ask crowd members to articulate a feature common to two out of three displayed examples. In addition, we ask the crowd to provide binary labels for these discovered features on the remaining examples. The triples are chosen adaptively based on the labels of the prev...

The sliding-mode control of nonlinear uncertain systems with un-modeled first-order actuator dynamics has been considered. A 2-SMC scheme with adaptive switching rule has been proposed, and its effectiveness has been shown for a class of systems encompassing non zero-input-stable (ZIS) systems and non-BIBS stable plants. The proposed algorithm is easy to implement and therefore suited to being ...

In the setting of multiparty computation a set of parties with private inputs wish to compute some joint function of their inputs, whilst preserving certain security properties (like privacy and correctness). An adaptively secure protocol is one in which the security properties are preserved even if an adversary can adaptively and dynamically corrupt parties during a computation. This provides ...

The approach of subset selection in polynomial regression model building assumes that the chosen fixed full set of predefined basis functions contains a subset that is sufficient to describe the target relation sufficiently well. However, in most cases the necessary set of basis functions is not known and needs to be guessed – a potentially non-trivial (and long) trial and error process. In our...
