Dual communities in spatial networks

open access: yesNature Communications, 2022
Here the authors introduce dual communities, characterized by strong connections at their boundaries, and show that they are formed as a trade-off between efficiency and resilience in supply networks.

F-Geometry and Amari’s α-Geometry on a Statistical Manifold

open access: yesEntropy, 2014
In this paper, we introduce a geometry called F-geometry on a statistical manifold S using an embedding F of S into the space RX of random variables. Amari’s α-geometry is a special case of F-geometry.

Topographical anatomy of the annulus of Zinn

open access: yesScientific Reports, 2022
The anatomy and even existence of a common tendinous origin of the extraocular eye muscles, or annulus of Zinn, has widely been debated in anatomical literature. This study explored the anatomical origins of the recti muscles, their course into the orbit

A Downlink and Uplink Alignment Scheme for Power Saving in IEEE 802.16 Protocol

open access: yesThe Scientific World Journal, 2014
This study shows the problem of power saving mechanism (PSM) that sleep intervals of uplink (UL) connections do not synchronize with sleep intervals of downlink (DL) connections.

The Relations between Residuated Frames and Residuated Connections

open access: yesMathematics, 2020
We introduce the notion of (dual) residuated frames as a viewpoint of relational semantics for a fuzzy logic. We investigate the relations between (dual) residuated frames and (dual) residuated connections as a topological viewpoint of fuzzy rough sets ...
