Recent detections of gravitational waves from mergers neutron stars (NSs) and black holes (BHs) in the low high-end mass gap regimes pose a puzzle to standard stellar binary evolution theory. Mass-gap may originate successive hierarchical systems such as quadruples. Here, we consider repeated NSs BHs 2+2 quadruple systems, which secular can accelerate merger one inner binaries. Subsequently, re...

Phylogenetics study the evolutionary history of organisms using an iterative process creating and evaluating phylogenetic trees. This is very computationally intensive; constructing a large tree requires hundreds to thousands CPU hours. In this article, we describe FPGA-based system that can be deployed on AWS EC2 F1 cloud instances accelerate analyses by boosting performance likelihood functio...

An asteroidal triple in a graph is a set of three non-adjacent vertices such that for any two of them there exists a path between them that does not intersect the neighborhood of the third. An asteroidal quadruple is a set of four non-adjacent vertices such that any three of them is an asteroidal triple. In this paper, we study a subclass of directed path graph, the class of extended star direc...

The pons controls crucial sensorimotor and autonomic functions. In humans, it grows sixfold postnatally and is a site of paediatric gliomas; however, the mechanisms of pontine growth remain poorly understood. We show that the murine pons quadruples in volume postnatally; growth is fastest during postnatal days 0-4 (P0-P4), preceding most myelination. We identify three postnatal proliferative co...

This paper introduces a novel scheme which works on symbolizing every line in an object image for object recognition. Symbolizing is accomplished in terms of angles of intersection with regard to a line under consideration. Spatial relationship existing among the symbolized lines is represented using the notion of Triangular Spatial Relationship (TSR). A set of quadruples which preserves the TS...

Base sequences BS n 1, n are quadruples of {±1}-sequences A;B;C;D , with A and B of length n 1 and C and D of length n, such that the sum of their nonperiodic autocor-relation functions is a δ-function. The base sequence conjecture, asserting that BS n 1, n exist for all n, is stronger than the famous Hadamard matrix conjecture. We introduce a new definition of equivalence for base sequences BS...

In this paper, we summarise the lessons learnt from the PhD Thesis Exploiting RDFS and OWL for Integrating Heterogeneous, Large-Scale, Linked Data Corpora where we looked at three use-cases for reasoning over Linked Data: (i) translating data between different vocabulary terms; (ii) identifying and repairing noise in the form of inconsistency; and (iii) detecting and processing coreferent ident...
