Background The extracellular matrix (ECM) can directly or indirectly influence on regulation of cell functions such as cell adhesion, migration, proliferation and differentiation. The cell derived ECM (CD-ECM) is a useful in vitro model for studying the comprehensive functions of CD-ECM because it maintains a native-like structure and composition. In this study, the CD-ECM is obtained and a tes...

It is shown that for each odd integer q, there is a complex WilliamsonHadamard matrix of order 2(q)+1 ·2n (q)+1 . q. In a recent paper Craigen, Holzmann and Kharaghani [1] showed that for every odd integer q) there is an integer N( q) which does not exceed twice the number of nonzero digits in the binary expansion of q, such that the existence of an Orthogonal Design (OD) of order 2N (q)-1 impl...

We present a new technique for the visual exploration of origins (O) and destinations (D) arranged in geographical space. Previous attempts to map the flows between origins and destinations have suffered from problems of occlusion usually requiring some form of generalisation, such as aggregation or flow density estimation before they can be visualized. This can lead to loss of detail or the in...

Despite progress in pain management, chronic non-cancer pain (CNCP) represents still a clinical challenge. The efficacy and safety profile of tramadol make it suitable as a long-term treatment in a variety of CNCP conditions. New once-daily (OD) formulations of tramadol have been marketed in various countries, in order to offer the advantage of a reduced dosing regimen and to improve patients' ...

It is true in the Solovay model that every countable ordinal-definable set of sets of reals contains only ordinal-definable elements.

This paper proposes a two-stage algorithm to simultaneously estimate origin-destination (OD) matrix, link choice proportion, and dispersion parameter using partial traffic counts in a congested network. A non-linear optimization model is developed which incorporates a dynamic dispersion parameter, followed by a two-stage algorithm in which Generalized Least Squares (GLS) estimation and a Stocha...
