“Structural connections” in formal languages
Communications of the ACM, 1964This paper defines the concept of “structural connection” in a mechanical language in an attempt to classify various formal languages according to the complexity of parsing structures on strings in the languages. Languages discussed vary in complexity from those with essentially no structure at all to languages which are self-defining. The relationship

Structural connectivity in Parkinson's disease
Parkinsonism & Related Disorders, 2016In the last decades a rapid evolution of structural advanced MRI techniques has occurred supporting the diagnosis of idiopathic Parkinson's disease, allowing us to further investigate the disease progression from nigral to extra-nigral degeneration and finally to detect pre-manifest Parkinson's disease.

Partially connected structures for hybrid precoders have called attention because they reduce the number of phase shifters and eliminate the need for radio frequency (RF) adders. There are two categories of partial structures, fixed and dynamic. In fixed structures, each RF chain is connected to an antenna subarray, whereas in dynamic structures, the ...

Structure connectivity and substructure connectivity of Möbius cubes
The Computer JournalAbstract The connectivity is an important measurement for the fault-tolerance of networks. To provide more accurate measures for the fault-tolerance of networks than the connectivity, some generalizations of connectivity have been introduced.

Extra Connectivity and Structure Connectivity of 2-Dimensional Torus Networks
International Journal of Foundations of Computer Science, 2022The 2-dimensional torus networks, denoted by [Formula: see text], is a special case of the famous [Formula: see text]-dimensional torus network. The extra connectivity, structure connectivity and sub-structure connectivity are generalized connectivity to measure the fault-tolerance of the networks.

On the structure of cross connections and Galois connections
Korean Journal of Computational & Applied Mathematics, 1995We consider partially ordered set as passing from the set of ideals to the set of filters in Cartesian product of partially ordered sets. Lawson introduced the concept of cross connection with the ideal and filter. We show the relation between Galois connection and cross connection.

Structure of the tendon connective tissue
Scandinavian Journal of Medicine & Science in Sports, 2000Tendons consist of collagen (mostly type I collagen) and elastin embedded in a proteoglycan‐water matrix with collagen accounting for 65–80% and elastin approximately 1–2% of the dry mass of the tendon. These elements are produced by tenoblasts and tenocytes, which are the elongated fibroblasts and fibrocytes that lie between the collagen fibers, and ...

Structural connectivity in multiple sclerosis and modeling of disconnection
Multiple Sclerosis, 2019Background: Multiple sclerosis (MS) is characterized by focal white matter damage, and when the brain is modeled as a network, lesions can be treated as disconnection events.
