In earlier papers we studied direct limits (G,K) = lim −→ (Gn,Kn) of two types of Gelfand pairs. The first type was that in which the Gn/Kn are compact riemannian symmetric spaces. The second type was that in which Gn = Nn ⋊ Kn with Nn nilpotent, in other words pairs (Gn,Kn) for which Gn/Kn is a commutative nilmanifold. In each we worked out a method inspired by the Frobenius–Schur Orthogonalit...

Pyramidal neurons in layer 5 of the neocortex can be differentiated into 3 cell subtypes: 1) short regular spiking (SH), 2) tall regular spiking (TR), and 3) tall burst spiking (TB), based on their morphological and electrophysiological properties. We characterized the functional excitatory local input to these 3 cell subtypes in rat primary visual cortex using laser-scanning photostimulation. ...

The HIV-1 type dimerization initiation signal (DIS) loop was used as a starting point for the analysis of the stability of Watson-Crick (WC) base pairs in a tertiary structure context. We used ultraviolet melting to determine thermodynamic parameters for loop-loop tertiary interactions and compared them with regular secondary structure RNA helices of the same sequences. In 1 M Na+ the loop-loop...

In 2008, Vallentin made a conjecture involving the least distortion of an embedding distance-regular graph into Euclidean space. Vallentin’s implies that for diameter d, most contracted pairs vertices are those at distance d. this paper, we confirm several families graphs. We also provide counterexamples to conjecture, where largest contraction occurs between d−1. suggest three alternative conj...

Regular chest physiotherapy is advocated in non-cystic fibrosis bronchiectasis despite little evidence supporting its routine use. This study aimed to establish the efficacy of regular chest physiotherapy in non-cystic fibrosis bronchiectasis compared with no regular chest physiotherapy. 20 patients not practising regular chest physiotherapy were enrolled in a randomised crossover trial of 3 mo...

Objectives: Different treatment approaches have been introduced for children with Speech Sound Disorders (SSD). Minimal pair intervention, Metaphon therapy, and parents and children together approach as linguistically-based approaches are routinely utilized in this population and both of them shared minimal pairs as a common component. The purpose of the current study was to develop and investi...

Aims To investigate the role of measured risk factors and the influence of genetic and environmental factors on regular cigarette smoking. Design Members of monozygotic and dizygotic, including unlike-sex twin pairs ( n = 6257) from a young adult cohort from the Australian Twin Registry. Methods Cox proportional hazards models were used to determine whether putative risk factors were significan...
