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

Four Dimensional Integrable Theories [PDF]

open access: yes, 1994
There exist many four dimensional integrable theories. They include self-dual gauge and gravity theories, all their extended supersymmetric generalisations, as well the full (non-self-dual) N=3 super Yang-Mills equations.

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.

On Information Geometrical Structures

open access: yesHittite Journal of Science and Engineering, 2018
Information geometry is a modern differential geometric approach to statistics, in particular theory of information. The main motivation for this expository survey article is the lack of compact material that mainly address to mathematical audience ...

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 ...

A Proof of Tarski’s Fixed Point Theorem by Application of Galois Connections [PDF]

open access: yes, 2014
Two examples of Galois connections and their dual forms are considered. One of them is applied to formulate a criterion when a given subset of a complete lattice forms a complete lattice.

Noncommutative connections on bimodules and Drinfeld twist deformation [PDF]

open access: yes, 2014
Given a Hopf algebra H, we study modules and bimodules over an algebra A that carry an H-action, as well as their morphisms and connections. Bimodules naturally arise when considering noncommutative analogues of tensor bundles.

Dual-hub connectivity: a case study on China Eastern Airlines in Shanghai

open access: yesEuropean Transport Research Review, 2019
To deal with slot constraints and insufficient capacity, emerging multi-airport systems have been under construction in China. This paper chose China Eastern Airlines as a case study, evaluating its hub connectivity under a dual-hub circumstance in ...
