Viral Diversity of Microbats within the South West Botanical Province of Western Australia

Abstract: Bats are known reservoirs of a wide variety of viruses that rarely result in overt clinical disease in the bat host. However, anthropogenic influences on the landscape and climate can change species assemblages and interactions, as well as undermine host-resilience. The cumulative result is a disturbance of bat–pathogen dynamics, which facilitate spillover events to sympatric species, and may threaten bat communities already facing synergistic stressors through ecological change. Therefore, characterisation of viral pathogens in bat communities provides important basal information to monitor and predict the emergence of diseases relevant to conservation and public health. This study used targeted molecular techniques, serological assays and next generation sequencing to characterise adenoviruses, coronaviruses and paramyxoviruses from 11 species of insectivorous bats within the South West Botanical Province of Western Australia. Phylogenetic analysis indicated complex ecological interactions including virus–host associations, cross-species infections, and multiple viral strains circulating concurrently within selected bat populations. Additionally, we describe the entire coding sequences for five alphacoronaviruses (representing four putative new species), and one novel adenovirus. Results indicate that viral burden (both prevalence and richness) is not homogeneous among species, with Chalinolobus gouldii identified as a key epidemiological element within the studied communities.

Imaging wool fiber surfaces with a scanning force microscope

Abstract: Surfaces of wool scales are imaged using a scanning force microscope (SFM) and a field emission scanning electron microscope (FESEM). Atomic force microscope (AFM) images of wool fiber surfaces can be correlated with FESEM micrographs to provide complementary views of surface features. The AFM images are analyzed for scale height; on average there is a 21% increase when changing from air to water. The variability of scale height changes is large, and a model involving both swelling and scale move ment has been proposed. Lateral force microscope (LFM) images show complementary information to topographic AFM images and reveal the effects of surface treatment not available with other imaging techniques. Such images of treated wool surfaces reveal major inhomogeneities in friction, which are interpreted as differences in chem ical composition.

Full-Order observer design for nonlinear complex large-scale systems with unknown time-varying delayed interactions

Abstract: This article is concerned with the problem of state observer for complex large-scale systems with unknown time-varying delayed interactions. The class of large-scale interconnected systems under consideration is subjected to interval time-varying delays and nonlinear perturbations. By introducing a set of argumented Lyapunov-Krasovskii functionals and using a new bounding estimation technique, novel delay-dependent conditions for existence of state observers with guaranteed exponential stability are derived in terms of linear matrix inequalities LMIs. In our design approach, the set of full-order Luenberger-type state observers are systematically derived via the use of an efficient LMI-based algorithm. Numerical examples are given to illustrate the effectiveness of the result. © 2014 Wiley Periodicals, Inc. Complexity 21: 123-133, 2015
