We analyze the structure of reduced expressions in the Coxeter groups An, Bn and Dn. Several special classes of elements are singled out for their connections with symmetric functions or the theory of P -partitions. Membership in these special classes is characterized in a variety of ways, including forbidden patterns, forbidden subwords, and by the form of canonically chosen reduced words.

We introduce and study a class of simplicial complexes, the orphan complexes, associated to simple graphs whose family of (open or closed) vertex-neighborhoods are anti-Sperner. Under suitable restrictions, we show that orphan complexes of such graphs are always shellable and provide a characterization of graphs in terms of induced forbidden subgraphs contained in this restricted subfamily.

In this paper we demonstrate that several theorems from [1] and [3] do not hold as they are stated. These are the theorems regarding forbidden subposet characterizations of certain classes of coverincomparability graphs. In this paper we correct a mistake in the main theorem of [1], reformulate the corresponding statements and present corrected proofs. We further characterize posets whose cover...

Venipuncture is one of the most often performed invasive clinical procedure. Nevertheless, complications still occur. One opportunity to counteract these indicate insertion by electrical impedance measurement, which bases on various properties different tissues. This paper presents evaluation and reproducible fabrication simple tissue-mimicking phantoms for investigation sensing techniques. Thr...

objective: because of the therapeutic application of stem cells (scs), isolation and characterization of different types of scs, especially mesenchymal stem cells (mscs), have gained considerable attention in recent studies. adipose tissue is an abundant and accessible source of mscs which can be used for tissue engineering and in particular for treatment of musculoskeletal disorders. this stud...

Take-home messages: • A broad range of cardiovascular conditions affect the myocardium. • The presence and extent to which the myocardium is affected can be estimated with magnetic resonance-based tissue characterization techniques. • The extent to which these techniques have been validated varies; the certainty with which a cardiac magnetic resonance (CMR)-based tissue characteristic is assign...

Chronic rhinosinusitis (CRS) is a heterogeneous disease. Possibilities for subclassification exist via the phenotype and by endotyping based on inflammatory infiltrate in local tissue. As an interesting component of innate immune defense, cytotoxic cytokine-producing natural killer cells (NK) as tissue-based can have direct influence pathogenesis. Thus, aim this work was precise characterizatio...
