Let \(V\) be a left vector space over a skew field \(K\) and let \( PG(V,K)\) be the projective geometry of the \(K\)-subspaces of \(V\). A spread of \(PG(V,K)\) is a family of mutually skew isomorphic subspaces that is a partition of the point set. The authors give a complete and self-contained proof of the characterization of desarguesian spreads of ...

Perineural spread (PNS) refers to the extent of tumor cells or other nonneoplastic lesions along the tissues of the nerve sheath, its overall incidence ranges from 2.5% to 5%. PNS is more frequently associated with carcinoma arising from minor or major salivary glands (more often adenoid cystic carcinoma), mucosal or cutaneous squamous cell carcinoma ...

Spreads which are Not Dual Spreads
Canadian Mathematical Bulletin, 1969In this note we show the existence of a spread which is not a dual spread, thus answering a question in [1]. We also obtain some related results on spreads and partial spreads.Let ∑ = PG(2t-l, F) be a projective space of odd dimension (2t-l, ≥2) over the field F. In accordance with [1] we make the following definitions.

A \((t - 1)\)-spread in \(\Sigma = PG(n - 1, q)\) is a family \({\mathcal S}\) of mutually disjoint subspaces of dimension \(t - 1\) which partition the points of \(\Sigma\). A necessary and sufficient condition for the existence of a spread is \(t |n\), and so we assume \(n = rt\) for some integer \(r\) from now on. There is a natural \(2 - (q^{rt}, q^

In most Lepidoptera, plasmatocytes and granulocytes are the two hemocyte classes capable of adhering to foreign targets. Previously, we identified plasmatocyte spreading peptide (PSP1) from the moth Pseudoplusia includens and reported that it induced plasmatocytes to rapidly spread on foreign surfaces.

SPREAD UNIFORMITIES AND UNIFORM SPREADS
Quaestiones Mathematicae, 2001We discuss a point free analog of the topological fact that every uniformly continuous function on a dense subspace of a uniform space into a complete uniform space has a unique continuous extension. It is shown that a uniform frame homomorphism h : L → M from a complete uniform frame L into a uniform frame M (not necessarily ...

The main conceptual and terminological issues related to lateral spreading as an extension of a cohesive and fractured rock or soil mass over a softer underlying material are presented and accompanied by a brief outline of the state-of-the-art on the topic. Then the geomorphic features related to the two main types of spreading (rock spreading and soil

Abstract This chapter deals with how parthenium weed (Parthenium hysterophorus), with a humble origin in the neotropics, has ended up as a global weed with a pantropical distribution spreading across about 48 countries in the last five to six decades.
