Non-wandering sets of the powers of maps of a tree
Let T be a tree and let Ω ( f ) be the set of non-wandering points of a continuous map f: T→ T. We prove that for a continuous map f: T→ T of a tree T: ( i) if x∈ Ω( f) has an infinite orbit, then x∈ Ω( fn) for e...

Effect of strain rate on the mechanical behaviors of SiC fiber
In the present paper, tensile experiments of SiC fiber bundles under different strain rates (quasi-static: 10−4–10−3 s−1, dynamic: 200–1200 s−1) are carried out and the corresponding stress-strain curves are obta...

Null Flows and Null Functions on \(\mathbb{R}\)
In this paper, we introduce the notion of null flows via sequence entropy. We study the structure of minimal null flows and show that such a flow is almost automorphic and uniquely ergodic. Moreover, minimal n...

A local variational relation and applications
In [BGH] the authors show that for a given topological dynamical system (X,T) and an open coveru there is an invariant measure μ such that infh μ(T,ℙ)≥h top(T,U) where infimum is taken over all partitions finer t...

Relative entropy tuples, relative u.p.e. and c.p.e. extensions
Relative entropy tuples both in topological and measure-theoretical settings, relative uniformly positive entropy (rel.-u.p.e.) and relative completely positive entropy (rel.-c.p.e.) are studied. It is shown t...

A local variational principle of pressure and its applications to equilibrium states
We prove a local variational principle of pressure for any given open cover. More precisely, for a given dynamical system (X, T), an open cover ...

Stable Sets and \(\epsilon\) -Stable Sets in Positive-Entropy Systems
In this paper, the chaoticity appearing in the stable and unstable sets of a dynamical system with positive entropy is investigated. It is shown that in any positive-entropy system, there is a measure-theoreti...

Metabolic Kinetics of tert-Butylhydroquinone and Its Metabolites in Rat Serum after Oral Administration by LC/ITMS
Liquid chromatography–ion trap mass spectrometry (LC/ITMS) was employed for a metabolic kinetics study of tert-butylhydroquinone (TBHQ) and its metabolites in rat serum after oral administration. The mean serum c...

Open AccessTranscriptomic profiling of bovine IVF embryos revealed candidate genes and pathways involved in early embryonic development
Early embryonic loss is a large contributor to infertility in cattle. Although genetic factors are known to affect early embryonic development, the discovery of such factors has been a serious challenge. The o...
