Acid chloride handles on various templates 49-51 were acylated with equimolar mixtures of 19 different appropriately protected amines to prepare non-peptidic polyamide libraries. The three templates possess different types of symmetry and offer varying degrees of 3D spatial diversity. Screening for trypsin inhibition employing a chromogenic assay identified the xanthane analog 52 (K, = 9.4 pM) as a moderately active, but structurally novel, inhibitor of trypsin (see Fig. 7) [37]. 

Spatial diversity—Reduction of interference by maintaining physical separation. 

In wireless communications system significant performance gains are achievable when Multi-Input Multi-Output (MIMO) architecture employing multiple transmit and receive antennas is used [6], Increased system capacity can be achieved in these systems due to efficient exploitation of spatial diversity available in MIMO channel. This architecture is particularly suitable for higher data rate multimedia communications [7]. 

This chapter contains one of the more diverse assortments of topics of any chapter in the volume. In it we discuss the viscosity of polymer solutions, especially the intrinsic viscosity the diffusion and sedimentation behavior of polymers, including the equilibrium between the two and the analysis of polymers by gel permeation chromatography (GPC). At first glance these seem to be rather unrelated topics, but features they all share are a dependence on the spatial extension of the molecules in solution and applicability to molecular weight determination. 

I he diverse range of phannacological actions of this structural class documents the belief that the naphthalene nucleus consists of a scaffold upon which vanous functional groups can be arranged tnd that the action elicited is a consequence of receptor response to the kind and spatial arrange ment of these functions... 

Disturbances that increase water scarcity promote the physical uniformity of river systems and the decrease of biological diversity in streams and rivers. The structure and functioning of heavily impacted river systems become mutually and strikingly similar, irrespective of the river s origin and the climate. The more intense and persistent the disturbance, the greater is the resemblance. On the other hand, river organisms use resources most efficiently in spatially heterogeneous chaimels, and under moderate disturbance frequencies, rather than in steady conditions, to which they are not adapted. 

The reasons for this are diverse and include the fact that models of cardiac cellular activity were among the first cell models ever developed. Analytical descriptions of virtually all cardiac cell types are now available. Also, the large-scale integration of cardiac organ activity is helped immensely by the high degree of spatial and temporal regularity of functionally relevant events and structures, as cells in the heart beat synchronously. 

The NMDA receptor has a heteromeric structure composed of two subunit types NRl and NR2, the latter having four subunits (NR2A-NR2D) (Fig. 10.2). Molecular genetic techniques have demonstrated that native NMDA receptors are likely to be composed of a combination of the NRl subunit (which can exist in eight different splice variants) and one or more of the four NR2 subunits which are the main determinants of functional diversity among the NMDA receptors (see Chapter 3 for further details). It has been shown that there are distinct developmental and spatial expression patterns of NMDA receptor NRl subunit splice variants and NR2 receptor subunits in the CNS.
