Dynamic properties of the dynamical system SFnm(X), SFnm(f))

open access: yesApplied General Topology, 2020
Let X be a continuum and let n be a positive integer. We consider the hyperspaces Fn(X) and SFn(X). If m is an integer such that n > m ≥ 1, we consider the quotient space SFnm(X). For a given map f : X → X, we consider the induced maps Fn(f) : Fn(X) → Fn(

Hereditarily Irreducible Maps [PDF]

open access: yes, 2020
A map f:X→Y from a continuum X onto a continuum Y is said to be hereditarily irreducible, if f(A)⊊f(B) for any subcontinua A and B such that A⊊B. We investigate properties of hereditarily irreducible maps between continua.

Irreducible Radial Dislocation of the Proximal Interphalangeal Joint of a Finger

open access: yesJournal of Orthopaedics, Trauma and Rehabilitation, 2015
Dislocations of the proximal interphalangeal joint (PIPJ) are often easily reduced with closed reduction and manipulation. Irreducible PIPJ dislocations are rare.

Homomorphic images of finite subdirectly irreducible unary algebras [PDF]

open access: yes, 2007
summary:We prove that a finite unary algebra with at least two operation symbols is a homomorphic image of a (finite) subdirectly irreducible algebra if and only if the intersection of all its subalgebras which have at least two elements is ...

Irreducible Toeplitz and Hankel matrices [PDF]

open access: yes, 2006
An infinite matrix is called irreducible if its directed graph is strongly connected.It is proved that an infinite Toeplitz matrix is irreducible if and only if almost every finite leadingsubmatrix is irreducible.

Role of Posterior Interfacetal Distraction and Grafting in Complex Atlantoaxial Dislocation

open access: yesEgyptian Spine Journal, 2019
Background Data: Atlantoaxial fixation, unlike subaxial spine, is still challenging due to complex topographical anatomy. Nowadays, atlas lateral mass screws and transpedicular axis screws fixation is a well-accepted technique for the management of ...

Study on the evaluation method and application of logging irreducible water saturation in tight sandstone reservoirs

open access: yesOpen Geosciences, 2022
Taking into consideration the difficulties in predicting the properties of liquid production and evaluating the irreducible water saturation of low-porosity and ultra-low-permeability sandstone reservoirs, the relationships between the irreducible water ...
