This paper addresses the question of whether anticipatory attention--i.e. attention directed towards an upcoming stimulus in order to facilitate its processing--is realized at the neurophysiological level by a pre-stimulus desynchronization of the sensory cortex corresponding to the modality of the anticipated stimulus, reflecting the opening of a thalamocortical gate in the relevant sensory mo...

In a canonical way we establish an AZ{identity (see [9]) and its consequences, the LYM{inequality and the Sperner{property, for the Boolean interval lattice. Further, the Bollobas{inequality for the Boolean interval lattice turns out to be just the LYM{ inequality for the Boolean lattice. We also present an Intersection Theorem for this lattice. Perhaps more surprising is that by our approach t...

The famous Erd˝ os-Heilbronn conjecture plays an important role in the development of additive combinatorics. In 2007 Z. W. Sun made the following further conjecture (which is the linear extension of the Erd˝ os-Heilbronn conjecture): For any finite subset A of a field F and nonzero elements a where p(F) is the additive order of the multiplicative identity of F , and δ ∈ {0, 1} takes the value ...

We present a new characterization of Erd?s space factors, and show that the $$\mathfrak{C}$$ is unstable in class almost zero-dimensional F??-spaces. The latter answers question by Dijkstra van Mill.

It is common knowledge among brain researchers that certain events, such as motor imagery, can elicit event-related synchronization/ desynchronization (ERD/ERS) of neurons in the brain, and that these phenomena manifest themselves in terms of band power changes in brain signals. There are, however, also important phase related changes in the brain signals associated with ERD/ERS which we invest...

In order to meet the increasing demand for high-performance and high-efficiency vehicles, this paper proposes a novel electromagnetic linear energy-reclaiming suspension technology based on McPherson independent suspension, analyzes its core component—ELA-ERD (Electromagnetic Linear Actuation Energy-Reclaiming Device). ELA-ERD, taking shock absorber piston rod as inner yoke, has compact structu...
