The time-delay signature (TDS) suppression of semiconductor lasers with external optical feedback is necessary to ensure the security chaos-based secure communications. Here we numerically and experimentally demonstrate a technique effectively suppress TDS chaotic using quantum noise. dynamical complexity are quantified autocorrelation function normalized permutation entropy at delay time, resp...

Constructing a scheme that satisfies such a strong security notion is very involved, so we start with an easier goal: unforgeability under a one-time chosen-message attack (uf-1cma). The definition is syntactically identical to the one above, but F is restricted to make (at most) one query to its signing oracle. Here we describe Lamport’s one-time signature scheme OTS for messages of length ` =...

We formalize the problem of analog data compression and analyze the existence of a polynomial data compression function. Under relaxed conditions we explore the existence of a solution employing digital signature analysis in the analog domain.

Conventional supervised classification of satellite images uses a single multi-band image and coincident ground observations to construct spectral signatures of land cover classes. We compared this approach with three alternatives that derive signatures from multiple images and time periods: (1) signature generalization: spectral signatures are derived from multiple images within one season, bu...

We prove that the finite representation property holds for representation by partial functions for the signature consisting of composition, intersection, antidomain and range. It follows that the finite representation property holds for any expansion of this signature with the fixset, preferential union, maximum iterate and opposite operators. The proof shows that for all these signatures the s...

Gastric cancer (GC) is one of the most common types of cancer and the second leading cause of cancer-associated mortality. Identification of novel biomarkers is critical to prolonging patient survival. MicroRNAs (miRNAs) proved to play diverse roles in the physiological and pathological state in cancers including GC. Herein we were aimed at performing a meta-analysis on miRNA profiling studies ...

The Internet of Things will include many resource-constrained wireless sensing devices, hungry for energy, bandwidth and compute cycles. The sheer amount of devices involved will require new solutions to handle issues such as identification and power provisioning. In this contribution, we analyze the energy needs of several public-key based authentication protocols, taking into account the ener...

Superconformal algebras embedding space-time in any dimension and signature are considered. Different real forms of the R-symmetries arise both for usual space-time signature (one time) and for Euclidean or exotic signatures (more than one times). Application of these superalgebras are found in the context of supergravities with 32 supersymmetries, in any dimension D ≤ 11. These theories are re...
