Power-to-X technologies that convert renewable electricity to chemically stored energy in “X” may provide a gaseous, liquid or solid fuel that can be used in winter to provide both, heat and electricity, and thus replace fossil fuels that are cur

The angiopoietins regulate vascular maturation, angiogenesis and lymphangiogenesis via their Tie receptors that were long believed to be endothelium-specific. Here the authors show that angiopoietins activate and control pericyte function through per

If D = (V, A) is a digraph, its niche hypergraph Nℋ(D) = (V, ℰ) has the edge set ℰ={e⊆V||e|≥2∧∃ υ∈V:e=ND−(υ)∨e=ND+(υ)}{\cal E} = \{ {e \subseteq V| | e | \ge 2 \wedge \exists \, \upsilon \in V:e = N_D^ - ( \upsilon ) \vee e = N

If \(D = (V,A)\) is a digraph, its domination hypergraph \(\mathcal{DH}(D) = (V,\mathcal{E})\) has the vertex set \(V\) and \(e \subseteq V\) is an edge of \(\mathcal{DH}(D)\) if and only if \(e\) is a minimal dominating set of \(D\). We investigate

The Tie receptors with their Angiopoietin ligands act as regulators of angiogenesis and vessel maturation. Tie2 exerts its functions through its supposed endothelial-specific expression. Yet, Tie2 is also expressed at lower levels by pericytes and it

If D = (V,A) is a digraph, its niche hypergraph NH(D) = (V, E) has the edge set ℇ = {e ⊆ V | |e| ≥ 2 ∧ ∃ v ∈ V : e = N−D(v) ∨ e = N+D(v)}. Niche hypergraphs generalize the well-known niche graphs (see [11]) and are closely related to

We generalize the concept of exclusive sum labelings of graphs (cf. Miller et al., JCMCC 55:137---148, 2005) and determine the exclusive sum number for several classes of hypergraphs. The results disclose a significant difference between graphs (i.e.

Let G = ( V , E ) be a simple undirected graph. The neighborhood hypergraph N ( G ) = ( V , E N ) of G has the edge set E N = { e ⊆ V ∣ | e | ≥ 1 ∧ ∃ x ∈ V : e = N G ( x ) } . In a certain sense, this is a generalization of the well-known

The mainstays of the clinical diagnosis of melanoma are asymmetry, border irregularity, color variegation, and a diameter >6 mm, and any major progress in diagnostic accuracy will probably be related to the development of additional criteria. Such in
