Historically, the Australian Defence Force (ADF) has sourced all its blood supplies from the Australian Red Cross Blood Service. Recent ADF operations in the Middle East have highlighted a need to rely on other nations' blood supply systems. In 2008, the ADF embedded a surgical and intensive care team into the Netherlands-led forward health facility at the Uruzgan Medical Centre at Tarin Kowt i...
The Direction of Arrival (DOA) is regarded as the best initial sorting parameter for locating enemy radar. The Direction finding (DF) systems are employed for estimating the direction of arrival of radar installation. Among all the techniques Amplitude Comparison Direction Finding (ADF) technique is the simplest. The Amplitude Comparison DF compares amplitude of the signal at multiple receivers...
The effect of eight different alcohols including halogenols and alkanols on the structural transformation of aciddenatured ficin (ADF) at pH 2.5 was studied using farand near-UV circular dichroism (CD) and tryptophan fluorescence. Except methanol and ethanol, other alcohols induced α-helical structure in ADF, as revealed by the increase in MRE222nm values. The fluoro alcohols tested showed a hi...
The regulation of filopodial dynamics by neurotrophins and other guidance cues plays an integral role in growth cone pathfinding. Filopodia are F-actin-based structures that explore the local environment, generate forces and play a role in growth cone translocation. Here, we review recent research showing that the actin-depolymerizing factor (ADF)/cofilin family of proteins mediates changes in ...
Italian ryegrass (Lolium multiflorum) is an important cool-season, annual forage crop for the grassland rotation system in Southern China. The primary aim of breeding programs is always to seek to improve forage quality in the animal productivity system; however, it is time- and labor-consuming when analyzed excessive large number of samples. The main objectives of this study were to construct ...
Quantitative ADF-STEM imaging paired with image simulations has proven to be a powerful technique for determining the three dimensional location of substitutionally doped atoms in thin films. Expansion of this technique to lightly-doped nanocrystals requires an understanding of the influence of specimen mistilt on dopant visibility due to the difficulty of accurate orientation determination in ...
In this paper, we consider M-ary phase shifting keying (MPSK) and M-ary quadrature amplitude modulation (MQAM) data symbol burst transmission for adaptive decode-andforward (ADF) relay systems over quasi-static Rayleigh fading channels. A burst has pilot symbols and data symbols. From pilot symbols, we can estimate the channel gain and detect each relay node’s transmission mode for ADF schemes....
Neurites are the characteristic structural element of neurons that will initiate brain connectivity and elaborate information. Early in development, neurons are spherical cells but this symmetry is broken through the initial formation of neurites. This fundamental step is thought to rely on actin and microtubule dynamics. However, it is unclear which aspects of the complex actin behavior contro...
Adaptive infinite impulse response (IIR) digital filter implemented using a cascade of second order direct form allpass filters and a finite impulse response (FIR) filter, has the property of its poles converging to those of the unknown system. In this paper we implement the adaptive allpass-FIR digital filter using a lattice allpass filter with minimum number of multipliers. We then derive a s...
Right-tailed unit root tests have proved promising for detecting exuberance in economic and financial activities. Like left-tailed tests, the limit theory and test performance are sensitive to the null hypothesis and the model specification used in parameter estimation. This paper aims to provide some empirical guidelines for the practical implementation of right-tailed unit root tests, focussi...
